Description
[0001] The present invention claims priority on U.S. Provisional
Patent Application Ser. No. 60/961,315 filed Jul. 20, 2007 entitled
"Attachment System," which is incorporated herein by reference.
[0002] The present invention is directed to transport devices, and
particularly to transport devices that carry fragile materials, and
even more particularly to a glass transportation cart that is used
to transport glass panes, assembled glass units, IGU's, framed
glass, glass window frames, etc. The glass transportation cart of
the present invention includes an arrangement and method for
holding a cushioning media on the glass transportation cart, which
arrangement and method for holding does not require the use of
traditional fasteners or adhesives, thereby protecting the glass
panes, glass frames, etc. glass panes, assembled glass units, IGUs,
framed glass, etc. in the glass transportation cart from accidental
contact with hard substances and subsequent breakage. The holding
arrangement and method for holding also can be designed to allow
for easy replacement of the cushioning media.
BACKGROUND OF THE INVENTION
[0003] Glass transportation carts have traditionally been used to
transport glass to the customers. All of these carts have some sort
of cushioning material attached to them to provide separation of
the glass from the cart and to insulate the glass from the
vibration of the cart as the glass is transported on the cart.
[0004] A common cushioning material that is used on glass
transportation carts is Homasote. The standard method of attaching
Homasote to the glass transportation cart is to use mechanical
fasteners (e.g., nails, staples, rivets, screws, etc.) and/or
adhesives. One or more of these methods of attachment are used by
each of the major cart manufacturers (e.g., GED, HMS, ESCP, Gregory
Manufacturing and Bromer).
[0005] Each of these attachment methods for Homasote has its
inherent drawbacks. The adhesive, when used, tends to not wick into
the Homasote, thus only provides a light surface bond between the
Homasote and the cart. Given the nature of Homasote, this bond is
short lived because the material of the Homasote flakes away at the
bond surface, thus the Homasote disengages from the cart after a
short period of use. The mechanical fasteners, when used, generally
fail in one or two ways. Homasote is formed of an absorbent
material. As such, the Homasote can absorb moisture during use,
which moisture absorption can cause the Homasote to expand and then
contract when the Homasote is exposed to wet and dry environments.
The repeated expansion and contraction of the Homasote can result
in the mechanical fastener being pulled off and/or loosened from
the Homasote. When the mechanical fastener is pulled partially out
of the Homasote, there is an increased chance the mechanical
fastener will contact the glass panes, glass frames, etc. on the
cart, thus potentially causing damage or breakage to the glass
panes, glass frames, etc. while the glass panes, glass frames, etc.
are being transported on the cart. Another failure mode for
mechanical fasteners is that the location of the mechanical
fastener provides only local support to the Homasote; generally at
the location that the mechanical fastener secures the Homasote to
the cart. As such, as the glass panes, glass frames, etc. are
dragged across the surface of the Homasote as the glass panes,
glass frames, etc. are inserted onto and/or removed from the cart,
the drag force on the Homasote surface creates bending moments in
the Homasote, which bending moments can lead to the shearing of the
Homasote and the ultimate disengagement of the Homasote from the
cart. Historically, users attempted to overcome this second mode of
failure by increasing the number of mechanical fasteners; however,
the increased number of mechanical fasteners increased the
likelihood of glass/metal contact with the mechanical fasteners.
When either or both of the attachment methods fail, the glass
panes, glass frames, etc. on the cart is exposed to a more
hazardous environment during transport, thereby resulting in a
higher tendency of breakage or damage to the glass panes, glass
frames, etc. The use of Homasote on glass transportation carts has
resulted in a large and ongoing expense of both material and labor
to keep the Homasote in a serviceable condition on the glass
transportation carts.
[0006] There have been attempts by manufacturers to find
alternatives to the use of Homasote on glass transportation carts.
One alternative material is the use of a plastic material. There
have been some attempts to substitute a UHMW plastic strip for the
Homasote. The plastic strip is generally more cut-resistant to
glass than Homasote; however, it was found that sealants commonly
used on glass frames have a tendency to adhere to the plastic
surface when the glass frames were placed in the carts. As such,
some of the glass frames were difficult to remove from the cart
and/or resulted in damage or breakage to the glass frame when
removed from the cart. Consequently, even though the plastic
material was more durable material than Homasote, and was also
found to better adhere to the cart as compared to Homasote, the use
of the plastic strip caused increased damage to the glass frames
when the glass frames were removed from the cart. The ability of
the Homasote to flake off when adhesive from a glass frame adheres
to the top surface of the Homasote enables the glass frame to be
easily removed from a cart using Homasote without damaging the
glass frame.
[0007] Some manufacturers have attempted to use mechanical
fasteners to secure Homasote to the top surface of the plastic
strip that was in turn secured to the cart. Such an arrangement
resulted in added cost, and also resumed the high maintenance costs
of Homasote repairs, and also increased the risk of the mechanical
fasteners contacting the glass panes, glass frames, etc. and
damaging the glass panes, glass frames, etc. on the cart.
[0008] On some glass transportation carts, there is an upright side
frame upon which the glass panes, glass frames, etc. are leaned
against during transport of the glass panes, glass frames, etc. on
the cart. Traditionally, Homasote was used on the upright side
frame of these carts to prevent damage to the glass panes, glass
frames, etc. The traditional methods of securing Homasote were used
to secure the Homasote on the upright side frame of the cart.
Because the forces exerted on the upright side frame of the cart
were generally less than the forces on the base of the cart when
glass panes, glass frames, etc. were inserted and removed from the
cart, the shearing off of the Homasote was less of a problem.
However, some manufacturers attempted to use plastic strips in the
place of Homasote. As with use of the plastic strip on the base of
the cart, the plastic strips on the upright side frame of the cart
resulted in the glass frames sticking to the plastic strips.
Silicone tape was used on the surface of the plastic strip to
prevent or reduce the sticking problem. Since less force was
applied to the upright side frame of the cart, the silicone tape
was believed to be durable enough for use on the cart. However, it
was found that the sharp edges of the glass frames resulted in the
tape being cut and damaged.
[0009] In view of the current state of the art of glass
transportation carts, there is a need for an improved glass
transportation cart that includes a fastening arrangement for
Homasote that overcomes the problem of prior glass transportation
carts.
SUMMARY OF THE INVENTION
[0010] The present invention is directed to glass transportation
carts that are used to transport glass panes, glass frames, etc.
glass panes, assembled glass units, IGUs, framed glass, etc. The
glass transportation cart of the present invention includes an
improved attachment arrangement for a cushioning media (e.g.,
Homasote, etc.) used on the glass transportation cart. The glass
transportation cart of the present invention may also include an
improved stacking arrangement for multiple glass transportation
carts; however, this is not required. The improved attachment
arrangement for the cushioning media is generally designed to
reduce the incidence of shearing of the cushioning media. The
improved attachment arrangement of the present invention is also
generally designed to reduce the incidence of damage or breakage of
the glass panes, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. on the glass transportation cart
that can result from contact of the attachment arrangement with the
glass panes, glass frames, etc. glass panes, assembled glass units,
IGUs, framed glass, etc. when the glass panes, glass frames, etc.
glass panes, assembled glass units, IGUs, framed glass, etc. are
positioned on and/or removed from the glass transportation cart.
The improved attachment arrangement of the present invention is
also generally designed to attach the cushioning media by an
arrangement that does not require traditional fasteners or
adhesives; however, this is not required. The improved attachment
arrangement of the present invention is also generally designed to
allow for easy replacement of the cushioning media; however, this
is not required.
[0011] In one non-limiting aspect of the present invention, the
improved attachment arrangement of the present invention includes a
hook arrangement. The hook arrangement is particularly directed to
securing a cushioning media (e.g., Homasote, etc.) to a glass
transportation cart that has an upright side frame on a dual frame
cart; however, it can be appreciated that the hook arrangement can
be used to secure the cushioning media to other locations on the
dual frame cart and/or on other types of glass transportation
carts. The hook arrangement is designed to provide an efficient and
effective arrangement to hang the cushioning media on one or more
regions of the glass transportation cart. The hook arrangement is
designed to secure the cushioning media to the glass transportation
cart in a manner that limits or prevents contact of the hook
arrangement with one or more glass panes, glass frames, etc. glass
panes, assembled glass units, IGUs, framed glass, etc. that are
positioned on the glass transportation cart. As such, by at least
partially isolating the hooking arrangement from the glass panes,
glass frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. on the glass transportation cart, the incidence of
damage to the glass panes, glass frames, etc. glass panes,
assembled glass units, IGUs, framed glass, etc. on the glass
transportation cart by the hook arrangement is significantly
reduced. In one non-limiting embodiment of the invention, the hook
arrangement is in the form of a specially configured hook. The
front portion of the hook includes an insertion section that is
designed to be inserted into and/or penetrate into the cushioning
media (e.g., Homasote, plastic, rubber, foam, wood, etc.). The
insertion section of the hook can include a sharpened end portion
to facilitate in the insertion into the cushioning media; however,
this is not required. The hook is generally designed such that the
insertion section engages a bottom region of the cushioning media
so that the hook at least partially supports the weight of the
cushioning media at the bottom region of the cushioning media;
however, this is not required. In one non-limiting aspect of this
embodiment, the thickness of the insertion section is less than
about 50% the thickness of the cushioning media. In another and/or
alternative non-limiting aspect of this embodiment, the thickness
of the insertion section is less than about 30% the thickness of
the cushioning media. In one non-limiting example, the thickness of
the cushioning media is about 0.2-1.5 inches, and generally about
0.25-0.5 inches and the thickness of the insertion section is about
0.05-0.1 inches; however, it can be appreciated that other
thickness of the cushioning media and/or the insertion section can
be used. In still another and/or alternative non-limiting aspect of
this embodiment, the insertion section is designed and has a
thickness such that when the insertion section is at least
partially inserted into the cushioning media, the insertion section
is located closer to the back wall of the cushioning media than to
the front wall of the cushioning media. In still another and/or
alternative non-limiting aspect of this embodiment, the insertion
section is designed and has a length such that when the insertion
section is inserted into the cushioning media, the insertion
section does not extend through the full width of the cushioning
media, thus the end of the insertion section is located inside the
cushioning media. In another and/or alternative non-limiting
embodiment of the invention, the hook includes a front transition
section that connects the bottom of the insertion section to the
bottom of the intermediate section of the hook. The front
transition section can be curved in shape; however, this is not
required. The intermediate section of the hook is designed to
extend along the back face of the cushioning media when the
insertion section engages the cushioning media. In one non-limiting
aspect of this embodiment, the intermediate section has a length
such that the intermediate section extends at least 50% the width
of the cushioning media when the insertion section is fully
inserted in the cushioning media. In another and/or alternative
non-limiting aspect of this embodiment, the intermediate section
has a length such that the intermediate section extends at least
75% of the width of the cushioning media when the insertion section
is fully inserted in the cushioning media. In one non-limiting
example, at least about 40% of the length of the insertion section
is generally parallel to a portion of the intermediate section;
however, this is not required. In still another and/or alternative
non-limiting embodiment of the invention, the hook includes a back
transition section that connects the top of the intermediate
section of the hook to the top of the arm section of the hook. The
back transition section can be curved in shape; however, this is
not required. The arm section of the hook is designed to secure the
hook to the glass transportation cart. The arm section is designed
to extend downwardly from the front transition section. The length
of the arm section is generally less than the length of the
intermediate section; however, this is not required. In one
non-limiting example, the length of the arm section is no more than
about 85% the length of the intermediate section. In another and/or
alternative non-limiting example, at least about 30% the length of
the arm section is generally parallel to a portion of the
intermediate section; however, this is not required. A portion of
the arm section can include a tension arrangement; however, this is
not required. Generally, the tension arrangement, when used, is
positioned at or near the bottom end of the arm section; however,
this is not required. The tension arrangement is generally designed
to facilitate in maintaining the hook on the glass transportation
cart. The hook is generally formed of a durable material (e.g.,
metal, plastic, etc.). In one non-limiting application of the hook
of the present invention, there is provided a dual frame glass
transportation cart having an upright side frame. Mounted in spaced
relationship to the front face of the upright side frame is a
durable strip of material (e.g., metal strip, plastic strip, etc.).
The spaced relationship between the front face of the upright side
frame and the durable strip forms a slot that enables the arm
section of the hook to be inserted therein. The durable strip can
be mounted to the upright side frame of the glass transportation
cart in a variety of ways (e.g., bolt, nail, screw, rivet,
adhesive, etc.). As can be appreciated, many other arrangements can
be used to form a slot or opening for the arm section of the hook
(e.g., the upright side frame of the glass transportation cart can
include openings and/or slots designed to receive the arm section;
the upright side frame and/or connected strip can include openings,
slots, ribs, etc. so as to form openings or slots for the arm
section, etc.). The tension arrangement on the arm section includes
an elbow portion that causes friction between the arm section and
the slot between the mounted durable strip and upright side frame
of the glass transportation cart so as to hold the arm section of
the hook in the slot. As can be appreciated, the arm portion can
have many other shapes and configurations that are used to secure
the arm section in the slot. The arm section is positioned in the
slot until the back transition section engages the top of the
durable strip. A cushioning media such as a strip of Homasote can
be inserted onto the insertion portion of the hook prior to or
after the arm section of the hook is inserted into the slot. The
hook is designed such that the back surface of the strip of
cushioning media is generally parallel to the front face of the
durable strip; however, this is not required. The arrangement for
the novel hook enables the cushioning media to be easily secured to
the upright side frame of the glass transportation cart. The
arrangement for the novel hook also enables the cushioning media to
be easily removed from the glass transportation cart. The removal
of the cushioning media from the glass transportation cart can be
accomplished by simply removing the arm section from the slot that
is formed between the durable strip and upright side frame of the
glass transportation cart, and/or by removing the cushioning media
from the insertion section on the hook.
[0012] In another and/or alternative non-limiting aspect of the
present invention, there is provided an attachment arrangement that
includes a base portion and two side walls that form a channel used
to at least partially secure a cushioning media therein. One of the
major problems associated with prior art attachment arrangements
for Homasote was that the use in the prior art attachment
arrangements provided only localized support for the Homasote. As
such, the Homasote was thus only held in place where the prior art
fastener is located. As glass panes, glass frames, etc. glass
panes, assembled glass units, IGUs, framed glass, etc. were dragged
over the surface of the Homasote, the glass panes, glass frames,
etc. glass panes, assembled glass units, IGUs, framed glass, etc.
pulled on and created a bending moment on the Homasote. This
bending moment could cause shearing of the Homasote, thereby
resulting in the Homasote being pulled off the glass transportation
cart. The weight of the glass panes, glass frames, etc. glass
panes, assembled glass units, IGUs, framed glass, etc. and/or the
vibration caused by the movement of the glass panes, glass frames,
etc. glass panes, assembled glass units, IGUs, framed glass, etc.
on the top surface of the Homasote caused the prior art fasteners
to become loose and/or run-out or lift out from the Homasote. Such
movement of the prior art fasteners resulted in increasing the
incidence of contact of the fasteners with the glass panes, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc., which contact could result in damage to the glass
panes, glass frames, etc. glass panes, assembled glass units, IGUs,
framed glass, etc. and/or cause the Homasote to premature release
from the glass transportation cart. The attachment arrangement of
the present invention overcomes these past problems associated with
prior art fasteners. The attachment arrangement can be formed of a
variety of materials (e.g., metal, plastic, composite material,
etc.). Typically, the attachment arrangement is formed of
non-corrosive materials (e.g., galvanized steel, tin-plated steel,
stainless steel, plastic, brass, aluminum, painted materials,
sealed materials, etc.); however, this is not required. In one
non-limiting embodiment of the present invention, the attachment
arrangement of the present invention includes a channel that is
designed to support the cushioning media along at least a majority
of the longitudinal length of the cushioning media that is exposed
to the glass panes, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc.; thereby inhibiting or preventing
the shearing of the cushioning media when the glass panes, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. are inserted on and/or removed from the glass
transportation cart. In another and/or alternative non-limiting
embodiment of the invention, the attachment arrangement that
includes a rail having a channel is designed to support the
cushioning media along at least about 60% of the longitudinal
length of the cushioning media. In still another and/or alternative
non-limiting embodiment of the invention, the attachment
arrangement that includes a rail having a channel is designed to
support the cushioning media along at least about 80% of the
longitudinal length of the cushioning media. In yet another and/or
alternative non-limiting embodiment of the invention, the
attachment arrangement that includes a rail having a channel is
designed to support the cushioning media along at least about 90%
of the longitudinal length of the cushioning media. In one
non-limiting embodiment of the invention, the rail includes two
side walls that at least partially form a channel. The channel can
have a generally U-shaped, cross-sectional shape; however, this is
not required. The size and shape of the two side walls are
generally the same along the longitudinal length of the rail;
however, this is not required. The two side walls extend generally
perpendicular to the plane of the base portion of the rail;
however, this is not required. If one or more of the side walls are
not extending generally perpendicular to the plane of the base
portion, one or both of the side walls can be angled inwardly into
the channel and/or outwardly from the channel at an angle of about
1-40.degree.. In another and/or alternative one non-limiting
embodiment of the invention, the side walls have a height that is
less than the thickness of the cushioning media so as to limit or
prevent contact of the top surface of the side walls with the glass
panes, glass frames, etc. glass panes, assembled glass units, IGUs,
framed glass, etc. that are positioned on the glass transportation
cart. Generally, the height of each side wall is less than about
90% the thickness of the cushioning media, typically less than
about 70% the thickness of the cushioning media, more typically
less than about 50% of the thickness of the cushioning media, and
even more typically about 5-35% of the thickness of the cushioning
media. In still another and/or alternative one non-limiting
embodiment of the invention, the base portion of the rail can
include one or more teeth, barbs and/or other or additional
non-smooth and/or gripping surfaces; however, the use of non-smooth
and/or gripping surfaces is not required. The use of the non-smooth
and/or gripping surfaces, when used, can be used to inhibit
movement of the cushioning media in the channel of the rail. As can
be appreciated, an adhesive alternatively or additionally can be
used to inhibit movement of the cushioning media in the channel of
the rail. The height of the non-smooth and/or gripping surfaces,
when used, is generally less than the height of the side walls. In
one non-limiting example, the height of the non-smooth and/or
gripping surfaces, when used, is less than about 90% of the height
of the side walls. In another non-limiting example, the height of
the non-smooth and/or gripping surfaces, when used, is less than
about 80% of the height of the side walls. In still another
non-limiting example, the height of the non-smooth and/or gripping
surfaces, when used, is less than about 70% of the height of the
side walls. In yet another and/or alternative one non-limiting
embodiment of the invention, the base portion and/or one or more of
the side walls of the rail can have a generally flat surface;
however, this is not required. In one non-limiting aspect of this
embodiment, a majority of the upper face of the base portion that
is designed to face the cushioning media lies in the same flat
planar plane. In another and/or alternative non-limiting aspect of
this embodiment, a majority of the inside face of the side walls
that are designed to face the cushioning media lie in the same flat
planar plane. In still another and/or alternative non-limiting
aspect of this embodiment, one or both side walls can include one
or more opening, slots, and/or non-smooth surfaces on one or more
portions of the side wall; however, this is not required. In still
yet another and/or alternative one non-limiting embodiment of the
invention, the spacing of the two side walls from one another can
be less than the width of the cushioning media, equal to the width
of the cushioning media, and/or greater than the width of the
cushioning media along one or more portions of the longitudinal
length of the attachment arrangement. In one non-limiting example,
the spacing of the inner surface of the two side walls from one
another is equal to the width of the cushioning media. In another
non-limiting example, the spacing of the inner surface of the two
side walls from one another is up to about 99.99% of the width of
the cushioning media. In still another non-limiting example, the
spacing of the inner surface of the two side walls from one another
is up to about 99.95% of the width of the cushioning media. In
still another non-limiting example, the spacing of inner surface of
the two side walls from one another is about 90-99.95% of the width
of the cushioning media. In yet another non-limiting example, the
spacing of the inner surface of the two side walls from one another
is about 95-99.9% of the width of the cushioning media. In still
yet another non-limiting example, the spacing of the inner surface
of the two side walls from one another is about 97.5-99.5% of the
width of the cushioning media. In still yet another and/or
alternative one non-limiting embodiment of the invention, the rail
can be secured to the glass transportation cart and/or to another
material that is in turn directly or indirectly connected to the
cart in a variety of ways. For example, the following non-limiting
connectors can be used individually or in some combination to
secure the rail: adhesive, clamp, wire, solder, weld, mechanical
fastener (e.g., rivet, bolt, nail, screw, staple, rope, string,
Velcro, etc.), etc. The rail can be designed to be removably
connected to the glass transportation cart or permanently connected
to the glass transportation cart. The base portion of the rail can
include one or more slots and/or openings. The one or more openings
and/or slots can be used to secure the rail to the glass
transportation cart; however, this is not required. One or more
rails can be used to secure the cushioning media along the
longitudinal length of the cushioning media to the glass
transportation cart.
[0013] In still another and/or alternative non-limiting aspect of
the present invention, there is provided an attachment arrangement
that includes a rail that has a base portion and two side walls
that form a channel that is used to at least partially secure a
cushioning media therein, which one or both of the side walls
include a non-planar wall configuration. In one non-limiting
embodiment of the invention, one or both of the side walls has a
cross-sectional shape that enables one or both side walls to at
least partially retract when the cushioning media is inserted into
the channel. Many different cross-sectional shapes of the one or
both side walls can be used to accomplish this side wall feature
(e.g., C-shaped cross-sectional shape, V-shaped cross-sectional
shape, 7-shaped cross-sectional shape, U-shaped cross-sectional
shape, L-shaped cross-sectional shaped, J-shaped cross-sectional
shape, etc.). The one or both side walls can also be designed to at
least partially spring back during and/or after the cushioning
media has been inserted in the channel; however, this is not
required. In one non-limiting arrangement, at least one of the side
walls has a generally C-shaped configuration. Various types of
C-shaped configurations can be used for one or both side walls. The
C-shaped configuration and/or other cross-sectional shapes of one
or more of the side walls can be used to facilitate in better
maintaining the cushioning media in the channel. When the
cushioning media is inserted into the channel, and the distance
between the top or front edges of the two side walls is less than
the width of the cushioning media, the insertion of the cushioning
media into the channel will cause the one or more C-shaped and/or
other cross-sectional shaped side walls to slightly spring backward
to enable the cushioning media to be inserted into the channel.
Once the cushioning media is inserted into the channel, one or both
of the C-shaped and/or other cross-sectional shaped side walls will
attempt to spring back into place resulting in the top or front
edges of the C-shaped and/or other cross-sectional shaped side
walls to dig slightly into one or both sides of the cushioning
media. The springing back of the one or more C-shaped and/or other
cross-sectional shaped side walls also can create a downward force
on the cushioning media to facilitate in causing the cushioning
media to move further into the channel. The front edge or lip of
the C-shaped and/or other cross-sectional shaped side walls also
provides lateral support to the cushioning media that is positioned
in the channel. One or more of these effects of the springing back
of the C-shaped and/or other cross-sectional shaped side walls
facilitate in securing the cushioning media in the channel. The one
or two C-shaped and/or other cross-sectional shaped side walls can
result in the cushioning media being able to be pushed and inserted
into the channel, yet still inhibit or prevent the cushioning media
from being easily lifted out of the channel. The "spring effect" of
the one or more C-shaped and/or other cross-sectional shaped side
walls allows the one or two side walls to move apart from one
another when the cushioning media is inserted into the channel, and
also causes the front edge of the C-shaped and/or other
cross-sectional shaped side wall to spring back and then grab into
the side of the cushioning media to thereby facilitate in securing
the cushioning media in the channel. Any force applied to the
cushioning media which tries to pull the cushioning media up and
out of the channel causes the front edges of the C-shaped and/or
other cross-sectional shaped side walls to bite deeper into the
side of the cushioning media, thereby further securing the
cushioning media in the channel. The C-shaped and/or other
cross-sectional shaped profile of one or both of the side walls
also provided an easy way for the cushioning media to be pushed out
along the longitudinal length of the channel when replacing and/or
removing the cushioning media from the channel. In another and/or
alternative non-limiting embodiment of the invention, when both
side walls include a C-shape and/or other cross-sectional shape,
the size and shape of the two side walls are generally the same
along the longitudinal length of the attachment arrangement;
however, this is not required. In still another and/or alternative
non-limiting embodiment of the invention, the height of the one or
both side walls that include a C-shape and/or other cross-sectional
shape is generally less than the thickness of the cushioning media.
In one non-limiting aspect of this embodiment, the height of the
C-shaped and/or other cross-sectional shaped side wall is less than
about 95% of the thickness of the cushioning media. In another one
non-limiting aspect of this embodiment, the height of the C-shaped
and/or other cross-sectional shaped side wall is less than about
90% the thickness of the cushioning media. In still another
non-limiting aspect of this embodiment, the height of the C-shaped
and/or other cross-sectional shaped side wall is less than about
75% the thickness of the cushioning media. In yet another
non-limiting aspect of this embodiment, the height of the C-shaped
and/or other cross-sectional shaped side wall is less than about
60% the thickness of the cushioning media. In still yet another
non-limiting aspect of this embodiment, the height of the C-shaped
and/or other cross-sectional shaped side wall is less than about
50% the thickness of the cushioning media. In another non-limiting
aspect of this embodiment, the height of the C-shaped and/or other
cross-sectional shaped side wall is about 5-35% the thickness of
the cushioning media. In yet another and/or alternative
non-limiting embodiment of the invention, the spacing of the top
edges of the two side walls from one another can be less than the
width of the cushioning media, equal to the width of the cushioning
media, and/or greater than the width of the cushioning media along
one or more portions of the longitudinal length of the side walls.
In one non-limiting example, the spacing of the top or front edges
of the two side walls from one another is equal to the width of the
cushioning media. In another non-limiting example, the spacing of
the top of front edges of the two side walls from one another is up
to about 99.99% the width of the cushioning media. In still another
non-limiting example, the spacing of the top or front edges of the
two side walls from one another is up to about 99.95% the width of
the cushioning media. In still another non-limiting example, the
spacing of the top or front edges of the two side walls from one
another is about 90-99.95% the width of the cushioning media. In
yet another non-limiting example, the spacing of the top or front
edges of the two side walls from one another is about 95-99.9% the
width of the cushioning media. In still yet another non-limiting
example, the spacing of the top or front edges of the two side
walls from one another is about 97.5-99.5% the width of the
cushioning media.
[0014] In yet another and/or alternative non-limiting aspect of the
present invention, there is provided an attachment arrangement that
includes a rail having a base portion and two side walls that form
a channel for at least partially securing a cushioning media
therein, which one or both of the side walls include one or more
slots so that the side wall is at least partially segmented along
the longitudinal length of the side wall. The one or more slots,
when used, allow the side wall to accommodate more variation along
the width of the cushioning media. The slots can have the same or
different size, configuration and/or spacing from one another. When
both side walls include one or more slots, the slots on the two
side walls can have the same or different size, configuration,
spacing from one another, and/or location along the length of the
side wall; however, this is not required.
[0015] Several non-limiting features of the attachment arrangement
that include a rail that having a channel are as follows: [0016] No
mechanical fasteners (staples/nails) are used to hold the
cushioning media in place. This feature inhibits or prevents
glass/metal contact which is common when the fasteners work loose
from the cushioning media. As such, the incidence of damage or
breakage to the glass panes, glass frames, etc. glass panes,
assembled glass units, IGUs, framed glass, etc. on the glass
transportation cart is reduced. [0017] No other known cart
manufacturer uses the attachment arrangement of the present
invention. [0018] The cushioning media can be installed without
tools. [0019] The strip of cushioning media can be quickly and
easily replaced when damaged without tools, thus reducing repair
time and labor requirements. [0020] The attachment arrangement can
accommodate different thicknesses of cushioning media without
changes to the attachment arrangement. [0021] The attachment
arrangement can accommodate different hardnesses of cushioning
media without changes to the attachment arrangement. [0022] The
attachment arrangement can accommodate physical changes in the
cushioning media (e.g., swelling and/or contraction of cushioning
media due to moisture content changes in the cushioning media,
etc.) without loss of holding strength of the attachment
arrangement to the cushioning media. [0023] The attachment
arrangement can provide excellent lateral support for the edges of
the strip of cushioning media, thereby reducing strip breakage
which can result in timely repairs. [0024] The attachment
arrangement can be made of a non-corroding or corrosion-resistant
material. [0025] The attachment arrangement can have a simple,
lightweight, and/or inexpensive design. [0026] The attachment
arrangement has a low profile that reduces or prevents incidences
of contact with the glass panes, glass frames, etc. glass panes,
assembled glass units, IGUs, framed glass, etc. on the glass
transportation cart. [0027] The inherent "spring design" of the one
or more C-shaped and/or other cross-sectional shaped side walls
holds the cushioning media in place and inhibits or prevents the
cushioning media from being lifted from the channel in the rail
when the glass panes, glass frames, etc. are moved onto and/or off
of the glass transportation cart and/or are lifted out of the glass
transportation cart. [0028] The attachment arrangement can be used
on a wide variety of different types and/or sizes of glass
transportation carts. [0029] The attachment arrangement can be
connected to the glass transportation cart using a variety of
connection arrangements (e.g., adhesive, nail, screw, rivet, bolt,
solder, welding, etc.). [0030] The attachment arrangement can be
connected vertically, horizontally, or at some other orientation on
the glass transportation cart and still hold and support the
cushioning media without having to modify the attachment
arrangement.
[0031] In still yet another and/or alternative non-limiting aspect
of the present invention, there is provided an improved flat bed
movable cart that is designed to transport glass panes, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. The flat bed movable cart has a main frame having a top
surface, a bottom surface, and a plurality of wheels. The top
surface of the main frame is generally parallel to a ground surface
upon which the wheels roll upon; however, this is not required. The
flat bed movable cart generally has two or more wheels. In one
non-limiting configuration, the flat bed movable cart includes four
wheels that are generally positioned on or about the four corners
of the frame. As can be appreciated, the wheels can be positioned
on or about other locations on the frame. In one non-limiting
embodiment of the invention, at least one wheel is generally
pivotally mounted to the frame so that the flat bed cart can be
easily turned when being moved on the ground surface; however, this
is not required. In another and/or alternative non-limiting
embodiment of the invention, the main frame has a generally
rectangular shape, however, it can be appreciated that other frame
shapes can be used. In still another and/or alternative
non-limiting embodiment of the invention, the main frame includes a
plurality of spacer bars that are positioned across the width of
the main frame; however, this is not required. The spacer bars,
when used, allow broken glass to easily fall to a ground surface.
As such, when glass inadvertently breaks, the glass falls to the
floor and does not accumulate on the top surface of the flat bed
cart. This spacer bar arrangement for the main frame makes the
cleanup of the glass much easier. This spacer bar arrangement for
the main frame also enables continued use of the flat bed cart for
transport of the remaining glass without having to unload the
remaining glass and then clean the broken glass off of the top
surface of the flat bed cart. In still another and/or alternative
non-limiting embodiment of the invention, the one or more spacer
bars on the main frame can be designed such that the top surface
and/or bottom surface of the one or more spacer bars are generally
parallel to the ground surface when the flat bed cart is positioned
on a ground surface; however, this is not required.
[0032] In another and/or alternative non-limiting aspect of the
present invention, there is provided an improved dual frame movable
cart that is designed to transport glass panes, glass frames, etc.
glass panes, assembled glass units, IGUs, framed glass, etc. The
dual frame cart includes a main frame and an upright side frame.
The main frame includes a top surface, a bottom surface, and a
plurality of wheels. The top surface of the main frame is generally
in a parallel relationship to a ground surface upon which the
wheels roll upon; however, this is not required. The dual frame
cart generally has two or more wheels. In one non-limiting
configuration, the dual frame cart includes four wheels that are
generally positioned on or about the four corners of the main
frame. As can be appreciated, the wheels can be positioned on or
about other locations on the main frame. In one non-limiting
embodiment of the invention, at least one wheel is generally
pivotally mounted to the main frame so that the dual frame cart can
be easily turned when being moved on the ground surface; however,
this is not required. In another and/or alternative non-limiting
embodiment of the invention, the main frame has a generally
rectangular shape, shape; however, it can be appreciated that other
frame shapes can be used. In still another and/or alternative
non-limiting embodiment of the invention, the main frame includes a
plurality of spacer bars that are positioned across the
longitudinal length of the main frame; however, this is not
required. The spacer bars, when used, allow broken glass to easily
fall to a ground surface. As such, when glass inadvertently breaks,
the glass falls to the floor and does not accumulate on the top
surface of the dual frame cart. This spacer bar arrangement for the
main frame makes the cleanup of the glass much easier. This spacer
bar arrangement for the main frame also enables continued use of
the dual frame cart for transport of the remaining glass without
having to unload the remaining glass and then clean the broken
glass off of the top surface of the dual frame cart. In still
another and/or alternative non-limiting embodiment of the
invention, a plurality of spacer bars on the main frame are mounted
in generally a parallel relationship to one another; however, this
is not required. In yet another and/or alternative non-limiting
embodiment of the invention, a plurality of spacer bars on the main
frame are mounted so that the top surface and/or bottom surface of
the spacer bars lie in generally the same plane as one another;
however, this is not required. In still another and/or alternative
non-limiting embodiment of the invention, the one or more spacer
bars on the main frame can be designed to such that the top surface
and/or bottom surface of the one or more spacer bars are generally
in a nonparallel relationship to the ground surface when the dual
frame cart is positioned on a ground surface; however, this is not
required. In one aspect of this embodiment, the one or more spacer
bars angle downwardly from one side of the main frame to the other
side of the main frame that has the upright side frame connected or
interconnected thereto. In one non-limiting arrangement, the one or
more spacer bars angle downwardly at a generally uniform angle;
however, this is not required. In another and/or alternative
non-limiting arrangement, a plurality of spacer bars angle
downwardly at generally the same angle; however, this is not
required. In still another and/or alternative non-limiting
arrangement, a plurality of spacer bars angle downwardly at an
angle of about 0.5-45.degree.. In yet another and/or alternative
non-limiting arrangement, a plurality of spacer bars angle
downwardly at an angle of about 1-40.degree.. In yet another and/or
alternative non-limiting arrangement, a plurality of spacer bars
angle downwardly at an angle of about 5-20.degree.; however, other
smaller or greater angles can be used in the dual frame cart. The
angular orientation of the space bars on the main frame result in
the glass panes, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. that are positioned on the dual
frame cart to tilt toward the upright side frame of the dual frame
cart. This angular positioning of the glass panes, glass frames,
etc. glass panes, assembled glass units, IGUs, framed glass, etc.
facilitates in maintaining the glass panes, glass frames, etc.
glass panes, assembled glass units, IGUs, framed glass, etc. in the
dual frame cart when the dual frame cart is moved. The angular
positioning of the glass panes, glass frames, etc. glass panes,
assembled glass units, IGUs, framed glass, etc. also enables the
dual frame cart to face in any direction in a truck or other type
of transport vehicle. As such, the angular positioning of the glass
panes, glass frames, etc. glass panes, assembled glass units, IGUs,
framed glass, etc. in the dual frame cart inhibits or prevents
sliding of the glass panes, glass frames, etc. glass panes,
assembled glass units, IGUs, framed glass, etc. off the dual frame
cart and/or rotation or flipping of the glass panes, glass frames,
etc. glass panes, assembled glass units, IGUs, framed glass, etc.
in the dual frame cart during movement of the dual frame cart. In
yet another and/or alternative non-limiting embodiment of the
invention, the upright side frame includes a front face and a back
face. In one non-limiting aspect of this embodiment, the upright
side frame has a generally rectangular shape, shape; however, it
can be appreciated that other frame shapes can be used. In another
and/or alternative non-limiting aspect of this embodiment, the
upright side frame includes a plurality of spacer bars that are
positioned across the longitudinal length of the upright side
frame; however, this is not required. The spacer bars, when used,
allow broken glass to easily fall to a ground surface. As such,
when glass inadvertently breaks, the glass falls to the floor and
does not accumulate on the upright side frame of the dual frame
cart. This spacer bar arrangement for the upright side frame makes
the cleanup of the glass much easier. This spacer bar arrangement
for the upright side frame also enables continued use of the dual
frame cart for transport of the remaining glass without having to
unload the remaining glass and then clean the broken glass off of
the dual frame cart. In one non-limiting arrangement, the spacer
bars on the upright side frame are mounted in generally a parallel
relationship to one another; however, this is not required. In
another and/or alternative non-limiting arrangement, the spacer
bars on the upright side frame are mounted so that the top surface
and/or bottom surface of the spacer bars lie in generally the same
plane as one another; however, this is not required. In still
another and/or alternative non-limiting embodiment of the present
invention, the angular relationship between the top surface of one
or more spacer bars on the main frame and the top surface of one or
more spacer bars on the upright side frame is about 70-120.degree.,
typically about 80-100.degree., and more typically about
90.degree..
[0033] In another and/or alternative non-limiting aspect of the
present invention, there is provided an improved configuration for
a glass transportation cart used to transport glass panes, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc., which glass transportation cart include one or more
spacer mounting arrangements that are used to mount one or more
glass separators on the glass transportation cart. The spacer
mounting arrangements can be designed to releasably secure the
glass separators to the glass transportation cart; however, this is
not required. In one non-limiting embodiment of the invention, one
or more spacer mounting arrangements are positioned in and/or
secured to one or more spacer bars on the main frame of the flat
bed cart or dual frame cart. As can be appreciated, one or more
spacer mounting arrangements can be positioned on and/or secured to
one or more other or additional locations on the flat bed cart or
dual frame cart. In one non-limiting configuration, the one or more
spacer mounting arrangements are designed to mount one or more of
the glass separators at an angle of about 45-90.degree. relative to
the top surface of one or more of the spacer bars on a flat bed
cart, typically at an angle of about 60-90.degree. relative to the
top surface of one or more of the spacer bars on a flat bed cart,
and more typically at an angle of about 80-90.degree. relative to
the top surface of one or more of the spacer bars on a flat bed
cart. In another and/or additional non-limiting embodiment of the
invention, one or more glass separators are secured to both the
main frame and upright side frame of the dual frame cart by a
spacer mounting arrangement. The one or more glass separators can
be mounted so as to be releasably connected to the main frame and
upright side frame of the dual frame cart or be permanently
connected to the main frame and upright side frame of the dual
frame cart. In one non-limiting configuration, the one or more
glass separators are mounted on the dual frame cart at an angle of
about 5-80.degree. relative to the top surface of one or more of
the spacer bars on the main frame, typically at an angle of about
15-70.degree. relative to the top surface of one or more of the
spacer bars on the main frame, and more typically at an angle of
about 30-50.degree. relative to the top surface of one or more of
the spacer bars on the main frame. In still another and/or
alternative non-limiting embodiment of the invention, the
cross-section of the spacer mounting arrangement is generally
selected to have a similar cross-sectional shape to the base
portion of the glass separator when the spacer mounting arrangement
is designed to at least telescopically receive at least a portion
of a glass separator; however, this is not required. In one
non-limiting arrangement, one or more of the spacer mounting
arrangements have a generally circular cross-sectional shape;
however, it can be appreciated that other cross-sectional shapes
can be used. In another and/or additional non-limiting embodiment
of the invention, the one or more glass separators have a rod-shape
configuration; however, it can be appreciated that one or more of
the glass separators can have other forms. The glass separators are
generally formed of a durable material (e.g., plastic, steel,
plastic coated steel, etc.). The glass separators can also or
alternatively be formed of a material and/or include a coating
material that is used to reduce damage to the glass panes, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. on the glass transportation cart; however, this is not
required. In yet another and/or alternative non-limiting embodiment
of the invention, the top surface of the one or more spacer
mounting arrangements is positioned below the level of the top
surface of the cushioning media so that the spacer mounting
arrangements do not contact the glass panes, glass frames, etc.
glass panes, assembled glass units, IGUs, framed glass, etc. that
are positioned on the glass transportation cart.
[0034] In still another and/or alternative non-limiting aspect of
the present invention, there is provided an improved configuration
for a glass transportation cart used to transport glass panes,
glass frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc., which glass transportation cart includes one or more
gates at the front and/or back end of the glass transportation
cart; however, this is not required. The use of one or more gates
is generally on the flat bed cart; however, it can be appreciated
that one or more gates can be used on a dual frame cart. The one or
more gates can be used to reduce damage to glass panes, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. that are positioned on the top surface of the glass
transportation cart by providing additional space between the glass
panes, glass frames, etc. glass panes, assembled glass units, IGUs,
framed glass, etc. on the glass transportation cart at one or both
ends of the glass transportation cart. The front end of the one or
more gates can include a shock absorbing material; however, this is
not required. In one non-limiting embodiment of the invention, the
one or more gates can be designed to slide and/or be repositioned
on the main frame of the glass transportation cart so as to
lengthen the top surface of the glass transportation cart to
thereby accommodate longer glass panes, glass frames, etc. glass
panes, assembled glass units, IGUs, framed glass, etc. In one
non-limiting configuration of the glass transportation cart, the
main frame and/or upright side frame of the glass transportation
cart includes one or more gate cavities to telescopically receive
at least a portion of the gate; however, this is not required. In
another and/or alternative non-limiting embodiment of the
invention, the one or more gates can include a locking arrangement
(e.g., pin, clip, bolt, latch, etc.) used to secure and/or lock the
one or more of the gates in position on the main frame and/or
upright side frame of the glass transportation cart; however, this
is not required. In still another and/or alternative non-limiting
embodiment of the invention, the one or more gates can be used to
stack two or more glass transportation carts on top of one another
to facilitate in the storage and/or transport of a plurality of
glass transportation carts. When the one or more gates are used for
stacking the glass transportation carts, one or more of the glass
transportation carts include one or more gate mounting
arrangements. In yet another and/or alternative non-limiting
embodiment of the invention, the one or more gate mounting
arrangements are generally positioned on the main frame portion of
the frame; however, it can be appreciated that the one or more gate
mounting arrangement can be also or alternatively positioned on one
or more of the spacer bars of the main frame. In still yet another
and/or alternative non-limiting embodiment of the invention, the
cross-section of the gate mounting arrangement is generally
selected to have a similar cross-sectional shape to the base
portion of the one or more gates; however, this is not required. In
one non-limiting arrangement, one or more of the gate mounting
arrangements have a generally polygonal cross-sectional shape
(e.g., rectangular, square, etc.); however, it can be appreciated
that other cross-sectional shapes can be used. In another and/or
alternative non-limiting embodiment of the invention, the top
surface of the one or more gate mounting arrangements is positioned
below the level of the top surface of the cushioning media on the
main frame so that the gate mounting arrangements do not contact
the glass panes, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. that are positioned on the glass
transportation cart; however, this is not required. In still
another and/or alternative non-limiting embodiment of the
invention, the one or more gate mounting arrangements can include a
locking arrangement (e.g., pin, clip, bolt, latch, etc.) used to
secure and/or lock the one or more of the gates in position in the
gate mounting arrangement; however, this is not required.
[0035] In yet another and/or alternative non-limiting aspect of the
present invention, there is provided an improved configuration for
a glass transportation cart used to transport glass panes, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc., which glass transportation cart includes one or more
guide mount arrangements designed to mount and/or connect to a
safety indicator and/or pull pole. In one non-limiting embodiment
of the invention, the safety indicator, when used, is designed to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0080] Referring now to the drawings wherein the showings are for
the purpose of illustrating preferred embodiments of the invention
only and not for the purpose of limiting same, FIG. 1A illustrates
a novel flat bed movable glass transportation cart 100 in
accordance with the present invention. The flat bed cart 100
includes a main frame 110 that has a top surface 112, a bottom
surface 114, two outside side surfaces 116, 118, two inside side
surfaces 120, 122, a front end surface 124, and a back end surface
126. The main frame has a generally rectangular shape; however, it
can be appreciated that other frame shapes can be used. The main
frame 110 is formed of two side rails 130, 132 and two end rails
134, 136. The main frame can be formed of a variety of durable
materials (e.g., metal, composite materials, plastic, reinforced
plastic, etc.). Four wheels 140 are mounted to the frame 110 to
enable the frame to be moved over a ground surface G. The wheels
are mounted on the frame and the frame is configured such that the
top surface 112 of the frame is generally parallel to the ground
surface G upon when the wheels 140 are in contact with the ground.
The four wheels are illustrated as positioned on the four corners
of main frame 110; however, this is not required. At least one
wheel is generally pivotally mounted to the frame so that the flat
bed cart can be easily turned when being moved on ground surface
G.
[0081] Main frame 110 includes a plurality of spacer bars 150 that
extend across the width of the main frame. The spacer bars are
illustrated as positioned about the same distance from one another
along the longitudinal axis of the main frame of the flat bed cart;
however, this is not required. The spacer bars can have the same
shape and size; however, this is not required. As illustrated in
FIG. 1B, the spacer bars can have different cross-sectional shapes.
The spacer bars are generally made of the same material as the main
frame; however, this is not required. The spacer bars 150 are
spaced from one another so as to allow broken glass to easily fall
to a ground surface. As such, when glass inadvertently breaks, the
glass falls to the ground surface and does not stay on the top
surface 112 of the flat bed cart. This novel arrangement makes
cleanup of broken glass much easier. This novel arrangement also
enables continued use of the flat bed cart for transport of the
remaining glass, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. that is still located on the flat
bed cart without having to unload the remaining glass, glass
frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. and then clean the broken glass off of the top surface
of the flat bed cart.
[0082] A plurality of spacer mounting arrangements 160 are mounted
on a plurality of spacer bars 150. The spacer mounting arrangements
are illustrated as in the form of cylindrically shaped tubes that
have a generally circular opening, and a generally cylindrical
cavity. As can be appreciated, the spacer mounting arrangements can
have other shapes. The spacer mounting arrangements are designed to
support glass separators 170. The glass separators are illustrated
as having a rod-like shape; however, it can be appreciated that the
glass separators can have other shapes. The glass separators can be
formed of a material and/or include a coating material to reduce
damage to the glass, glass frames, etc. glass panes, assembled
glass units, IGUs, framed glass, etc. on the flat bed cart;
however, this is not required. The glass separators are generally
designed to be releasably secured to the spacer mounting
arrangement; however, this is not required. As illustrated in FIG.
1A, a plurality of glass separators are inserted into the spacer
mounting arrangements so as to separate glass frames F and/or other
glass objects that are located on the flat bed cart so as to
inhibit or prevent the glass frames, etc. from contacting one
another while on the flat bed cart, thereby reducing the incidence
of damage to the glass frames, etc. while on the flat bed cart.
[0083] The flat bed cart is illustrated as including two stacking
gates 180 that are positioned at the front and back of the main
frame. The use of the stacking gates is optional. The stacking
gates are illustrated as including two legs 182, 184 and a cross
bar 186 attached therebetween. Each of the stacking gates is
illustrated as slidably extendable along the longitudinal axis of
the main frame; however, this is not required. The two legs of the
stacking gate are illustrated as telescopically received in a gate
cavity 190. The gate cavity has a generally tubular configuration
with an opening and cavity that is designed to enable the legs of
the stacking gate to slide into the cavity. The stacking gates are
generally locked or otherwise secured in the gate cavity by use of
a mechanical securing arrangement; however, this is not required.
When the stacking gates are positioned in the gate cavity, the
front end of the gate cavity can function as an abutment or bumper
that can be used to reduce damage to glass, glass frames, etc.
glass panes, assembled glass units, IGUs, framed glass, etc. that
are positioned in the flat bed cart. The front ends of the stacking
gates can include a shock absorbing material, not shown; however,
this is not required. The ability to slide the stacking gate along
the longitudinal axis of the main frame of the flat bed cart can be
used to provide additional space at the ends of the flat bed cart
to accommodate larger glass panes, glass frames, etc. glass panes,
assembled glass units, IGUs, framed glass, etc. that are positioned
on the flat bed cart.
[0084] A cushioning media 200 is illustrated as attached to the top
surface of the spacer bars. The cushioning media is designed to
function as a sliding and cushioning system used to reduce damage
to the glass panes, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. as the glass panes, glass frames,
etc. glass panes, assembled glass units, IGUs, framed glass, etc.
are positioned on the main frame, removed from the main frame,
and/or transported on the flat bed cart. The cushioning media can
be formed of many different materials such as, but not limited to,
Homasote, plastic strip, rubber strip, etc. One type of material
that works well with the flat bed cart of the present invention is
Homasote. The cushioning media can be mounted to the spacer bars by
a variety of arrangements. As will be discussed in more detail
below, several novel attachment arrangements in accordance with the
present invention can be used to secure the cushioning media to the
spacer bars.
[0085] The flat bed cart 100 can include one or more guide mount
arrangements 210 on the main frame; however, this is not required.
The guide mount arrangements are designed to support a pull pole
230 and/or safety indicator. The guide mount arrangements are
secure to the outside side surfaces 116, 118 of the main frame;
however, it can be appreciated that the guide mount arrangement can
be located in other or additional locations on the main frame. The
guide mount arrangements are illustrated as generally tubular
shaped and having a circular opening and a generally cylindrically
shaped cavity; however, it can be appreciated that the guide mount
arrangement can have other configurations. The guide mounting
arrangements are illustrated as secured at or near the corners of
the main frame; however, it can be appreciated that the guide
mounting arrangements can be located at other or additional
locations on the main frame. Pull pole 230 can be used by a user to
move and direct the flat bed cart to various locations. The pull
pole can also or alternatively be used to inhibit another glass
transportation cart, person, etc. from bumping the glass panes,
glass frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. on the flat bed cart. The pull pole is illustrated as
having a rod-like shape; however, it will be appreciated that the
pull pole can have other shapes.
[0086] The main frame can also include a plurality of gate mounting
arrangements 220; however, this is not required. The gate mounting
arrangements are used to support stacking gates 180 in a manner to
enable a plurality of flat bed carts to be stacked together as
illustrated in FIG. 1B. As illustrated in FIG. 1A, the gate
mounting arrangements are secured to the inside side surfaces 120,
122 of the main frame; however, it can be appreciated that the gate
mounting arrangement can be located in other or additional
locations on the main frame. The gate mounting arrangements are
illustrated as generally cuboid-shaped and have a generally square
opening designed to telescopically receive a portion of one leg of
the stacking gate; however, it can be appreciated that the gate
mounting arrangement can have other configurations. The gate
mounting arrangements are illustrated as secured at a location
spaced from the corners of the main frame; however, it can be
appreciated that the gate mounting arrangements can be located at
other or additional locations on the main frame. As illustrated in
FIG. 1B, the interior of the cavity of the gate mounting
arrangement can include a stop flange 222 or other device or
another type of internal configuration (e.g., narrowing of the
cavity, etc.) that prevents the leg of the stacking gate from
sliding fully through the cavity of the gate mounting arrangement;
however, this is not required. Referring to FIG. 1B, three flat bed
carts 100 are shown to be stacked on top of one another. Four of
the stacking gates 180 from the bottom two flat bed carts have been
removed from gate cavities 190 on the front and back portions of
the main frame and repositioned in the gate mounting arrangements
220 on the two lower flat bed carts.
[0087] Referring again to FIG. 1A, the outside surface of the main
frame can include a connector 240 that can be used to facilitate in
connecting the flat bed cart in a transport vehicle; however, this
is not required. Although not shown, the main frame of the flat bed
cart can include an information receptacle; however, this is not
required.
[0088] Referring now to FIGS. 2A, 2B, 2C and 3, there is
illustrated a dual frame glass transportation cart 300 in
accordance with the present invention. The dual frame cart 300
includes a main frame 310 that includes a top surface 312, a bottom
surface 314, two outside side surfaces 316, 318, two inside side
surfaces 320, 322, a front end surface 324, and a back end surface
326. The main frame has a generally rectangular shape; however, it
can be appreciated that other frame shapes can be used. The main
frame 310 is formed of two side rails 330, 332 and two end rails
334, 336. The main frame can be formed of a variety of durable
materials (e.g., metal, composite materials, plastic, reinforced
plastic, etc.). Four wheels 340 are mounted to main frame 310 to
enable the main frame to be moved over a ground surface G. The
wheels are mounted on the main frame and the main frame is
configured in a manner such that the top surface 312 of the frame
is generally parallel to the ground surface G when wheels 340 are
in contact with the ground. The four wheels are illustrated as
positioned on the four corners of main frame 310; however, this is
not required. At least one wheel is generally pivotally mounted to
the main frame so that the dual frame cart can be easily turned
when being moved on ground surface G.
[0089] Main frame 310 includes a plurality of spacer bars 350 that
extend across the longitudinal length of the main frame. The spacer
bars are illustrated as positioned about the same distance from one
another along the longitudinal axis of the main frame of the dual
frame cart; however, this is not required. The spacer bars can have
the same shape and size; however, this is not required. As
illustrated in FIG. 2A, the spacer bars can have different
cross-sectional shapes. The spacer bars are generally made of the
same material as the main frame; however, this is not required. The
spacer bars 350 are spaced from one another so as to allow broken
glass to easily fall to a ground surface. As such, when glass
inadvertently breaks, the glass falls to the ground surface and
does not stay on the top surface 312 of the dual frame cart. This
novel arrangement makes cleanup of broken glass much easier. This
novel arrangement also enables continued use of the dual frame cart
for transport of the remaining glass, glass frames, etc. glass
panes, assembled glass units, IGUs, framed glass, etc. that is
still located on the dual frame cart without having to unload the
remaining glass, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. and then clean the broken glass off
of the top surface of the dual frame cart.
[0090] The dual frame cart includes an upright side frame 500 that
is connected to one side of main frame 310. The upright side frame
can be connected to the main frame in a variety of ways (e.g.,
bolts, rivets, screws, weld, solder, adhesive, hinge, pins, etc.).
The upright side frame includes a top surface 502, a bottom surface
504, two outside side surfaces 506, 508, two inside side surfaces
510, 512, a front surface 514, and a back surface 516. The upright
side frame has a generally rectangular shape; however, it can be
appreciated that other frame shapes can be used. The upright side
frame 500 is formed of two side rails 520, 522 and a plurality of
spacer bars 530 connected therebetween. The upright side can be
formed of a variety of durable materials (e.g., metal, composite
materials, plastic, reinforced plastic, etc.). The upright side
frame and the main frame can be formed of the same materials;
however, this is not required.
[0091] The plurality of spacer bars 530 that extend across the
longitudinal length of the upright side frame are illustrated as
positioned about the same distance from one another; however, this
is not required. The spacer bars can have the same shape and size;
however, this is not required. As illustrated in FIG. 2A, the
spacer bars can have generally the same cross-sectional shape. The
spacer bars are generally made of the same material as the upright
side frame; however, this is not required. The spacer bars 530 are
spaced from one another so as to allow broken glass to easily fall
to a ground surface. As such, when glass inadvertently breaks, the
glass falls to the ground surface and does not accumulate on the
upright side frame of the dual frame cart. This novel arrangement
makes cleanup of broken glass much easier. This novel arrangement
of the upright side frame enables continued use of the dual frame
cart for transport of the remaining glass, glass frames, etc. glass
panes, assembled glass units, IGUs, framed glass, etc. that is
still located on the dual frame cart without having to unload the
remaining glass, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. and then clean the broken glass off
of the surfaces of the dual frame cart.
[0092] At least one reinforcement bar 360 can be connected between
the main frame and the upright side frame to provide added
structural integrity and rigidity to the dual frame cart. The
reinforcement members, when used, are generally secured at or near
the front and/or back ends of the dual frame cart; however, this is
not required. The reinforcement bars can be formed of a material
and/or include a coating material to reduce damage to the glass,
glass frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. on the dual frame cart; however, this is not required.
As illustrated in FIG. 2B, the reinforcement bar is secure to a
spacer bar on the main frame and a spacer bar on the upright side
frame. Many different types of connections can be used to secure
the reinforcement bar to one or more spacer bars and/or to one or
more portions of the main frame and/or upright side frame (e.g.,
weld, solder, bolt, screw, rivet, adhesive, pin, hinge, etc.).
[0093] A plurality of glass separators 370 are illustrated as
connected between the main frame and the upright side frame. The
glass separators are illustrated as having a rod-like shape;
however, it can be appreciated that the glass separators can have
other shapes. The glass separators can be formed of a material
and/or include a coating material to reduce damage to the glass,
glass frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc. on the dual frame cart; however, this is not required.
As illustrated in FIG. 2B, the glass separators are secured to a
spacer bar on the main frame and a spacer bar on the upright side
frame. Many different types of connections can be used to secure
the spacer bars to one or more spacer bars and/or to one or more
portions of the main frame and/or upright side frame (e.g., weld,
solder, bolt, screw, rivet, adhesive, pin, hinge, etc.). As
illustrated in FIGS. 2A, 2B and 3, a plurality of glass separators
are used to separate glass frames F and/or other glass objects that
are located on the dual frame cart so as to inhibit or prevent the
glass frames, etc. from contacting one another while on the dual
frame cart, thereby reducing the incidence of damage to the glass
flames, etc. while on the dual frame cart. As illustrated in FIG.
3, a plurality of reinforcement bars 360 can also be used in
conjunction with a plurality of glass separators 370 to separate
glass frames F and/or other glass objects that are located on the
dual frame cart. When this arrangement is used, a plurality of
reinforcement bars 360 and a plurality of glass separators 370 are
lined up with on another along the width of the main frame as
illustrated in FIG. 3. In one non-limiting configuration, the same
number of reinforcement bars 360 and glass separators 370 are used
in the dual frame cart. As illustrated in FIG. 2B, the slope angle
of the reinforcement bars 360 relative to the top surface of the
main frame is less than the slope angle of the glass separators 360
relative to the top surface of the main frame; however, this is not
required.
[0094] Referring now to 2A-C and 3, the spacer bars on the main
frame are mounted such that the top surfaces of the spacer bars
angle downwardly toward the side of the main frame upon which the
upright side frame is mounted. In addition, the spacer bars are
mounted progressively lower on the main frame the closer the spacer
bar is mounted to the side of the main frame upon which the upright
side frame is mounted. As best illustrated in FIG. 3, the upright
side frame is tilted backwardly from a fully upright position. The
angle of tilt of the upright side frame is selected such that the
angle formed between the top surface of the spacer bars on the main
frame and the top surface of the spacer bars of the upright side
frame is about 90.degree.; however, other angles can be formed. The
angled relationship of the spacer bars on the main frame in
conjunction with the backward tilting of the upright side frame on
the dual frame cart results in the glass frames F on the dual frame
cart being tilt toward the upright side frame when the glass frames
F are placed in the dual frame cart. This angular relationship
facilitates in maintaining the glass frames in the dual frame cart
when the glass frames are being transported in the dual frame cart.
As such, the angular relationship inhibits sliding of the glass
frames off the dual frame cart and/or rotation or flipping of the
glass frame in the dual frame cart as the dual frame cart
transports the glass frames. The tilt angle relative to the top
surface of the main frame is at least about 2.degree., generally
less than about 60.degree., and typically about 410-105.degree.;
however, other tilt angles can be used.
[0095] A cushioning media 380 is illustrated as attached to the top
surface of the spacer bars that are located on both the main frame
and the upright side frame. The cushioning media is designed to
function as a sliding and cushioning system used to reduce damage
to the glass panes, glass frames, etc. glass panes, assembled glass
units, IGUs, framed glass, etc. as the glass panes, glass frames,
etc. glass panes, assembled glass units, IGUs, framed glass, etc.
are positioned on the main frame, removed from the main frame,
and/or transported on the dual frame cart. The cushioning media can
be formed of many different materials such as, but not limited to,
Homasote, plastic strip, rubber strip, etc. One type of material
that works well with the dual frame cart of the present invention
is Homasote. The cushioning media can be mounted to the spacer bars
by a variety of arrangements. As will be discussed in more detail
below, several novel attachment arrangements in accordance with the
present invention can be used to secure the cushioning media to the
spacer bars.
[0096] The dual frame cart 300 can include one or more guide mount
arrangements 390 on the main frame; however, this is not required.
The guide mount arrangements are designed to support a pull pole
400 and/or safety indicator. The guide mount arrangements are
secure to the outside side surfaces of the main frame; however, it
can be appreciated that the guide mount arrangement can be located
in other or additional locations on the main frame. The guide mount
arrangements are illustrated as generally tubular shaped and having
a circular opening and having a generally cylindrically shaped
cavity; however, it can be appreciated that the guide mount
arrangement can have other configurations. The guide mounting
arrangements are illustrated as secured at or near the corners of
the main frame; however, it can be appreciated that the guide
mounting arrangements can be located at other or additional
locations on the main frame. Pull pole 400 can be used by a user to
move and direct the dual frame cart to various locations. The pull
pole can also or alternatively be used to inhibit another cart,
person, etc. from bumping the glass panes, glass frames, etc. glass
panes, assembled glass units, IGUs, framed glass, etc. on the dual
frame cart. The pull pole is illustrated as having a rod-like
shape; however, it will be appreciated that the pull pole can have
other shapes.
[0097] The upright frame 500 can include one or more pull handles
420 that can be used by a user to move and direct the dual frame
cart to various locations. As illustrated in FIG. 2A, the pull
handle, when used, can be located on one or both side rails 520,
522 of the upright side frame. The handles can be connected to the
upright side frame in a variety of ways. As can be appreciated, one
or more handles can be connected to the main frame; however, this
is not required.
[0098] Referring now to FIGS. 2A-C, connected to the outside
surface 316 of rail 330 is a bumper arrangement 430. The bumper
arrangement includes two legs 432, 434 that are secured to the
outside surface 316 of rail 330. The two legs can be connected to
the outside surface of rail 330 in a variety of ways (e.g., weld,
solder, bolt, screw, rivet, adhesive, pin, etc.). A bumper rail 436
is secured to the other end of the two legs 432, 434. The bumper
arrangement can be used to reduce damage to glass frames F that are
positioned on the dual frame cart by providing additional space
between the glass frames on the outer side surface of the dual
frame cart. The side bumper arrangement can include a shock
absorbing material; however, this is not required. Although not
shown, the main frame and/or the upright side frame of the dual
frame cart can include an information receptacle; however, this is
not required.
[0099] Referring now to FIGS. 2A-C, the dual frame cart can include
an arrangement to enable two or more dual frame carts to be stacked
on top of one another. The stacking arrangement, when used, can
include a set of stacking rails 440, 450 that are secured to the
upright side frame and main frame. Connected between the set of
stacking rails is a support bar 460. The support bar is used to
provide structural strength and rigidity to the stacking
arrangement. As best illustrated in FIGS. 2B and 2C, the bottom of
each stacking rail is secured to the outside surface 318 of side
rail 332 of the main frame. The top of each stacking rail is
secured to a top rail that is connected between side rails 520, 522
of the upright side frame. The manner in which the stacking rails
are secured to the upright side frame and the main frame are
non-limiting. Generally a weld is used to secure the stacking rails
to the upright side frame and the main frame. The top of each
stacking rail includes a connection extension 442, 452. The bottom
of each stacking rail includes an extension opening 444, 454. As
illustrated in FIG. 2C, the connection extension on one dual frame
cart is designed to be inserted into the extension opening of
another dual frame cart when two dual frame carts are stacked on
top of one another.
[0100] Referring to FIGS. 2B and 2C, at least one stacking gate
support 470 is secured to support bar 460. The stacking gate
support is designed to support a stacking gate 480 when the
stacking gate is not in use as illustrated in FIG. 2B. The stacking
gate support has a generally L-shape configuration; however, it
will be appreciated that other shapes can be used.
[0101] The stacking gate 480 includes two posts 482, 484 and a
connection bar 486 connected therebetween. At each end of the post
is a connection extension 488, 490. The connection extensions are
designed to be insertable into an opening 496, 498 of gate mounts
492, 494 as best illustrated in FIG. 2C. As illustrated in FIG. 2A,
gate mounts 492, 494 are secured to the outside surface 316 of rail
330. Generally, the two gate mounts are positioned directly across
from stacking rails 440, 450; however, this is not required. The
interior cavity of the gate mounts can include an obstruction to
limit the distance the connection extension can be inserted into
the cavity of the gate mounts; however, this is not required. As
illustrated in FIG. 2C, the shape of the two posts on the stacking
gate and the shape of the gate mounts can be used to limit the
distance the connection extension can be inserted into the cavity
of the gate mounts; however, this is not required.
[0102] Referring now to FIG. 4, there is illustrated one
non-limiting attachment arrangement for a cushioning media 380
(e.g., Homasote, etc.). The attachment arrangement is designed to
connect a strip of cushioning media to a spacer bar on the upright
side frame of a dual frame cart; however, it can be appreciated
that the attachment arrangement can also or alternatively be used
to connect the strip of cushioning media to a spacer bar on the
main frame of a dual frame cart or a flat bed cart. The attachment
arrangement is in the form of a specially configured hook 600. The
front portion 610 of hook 600 includes an insertion section 612
that is designed to be inserted into and/or penetrate the
cushioning media. The insertion section 612 can include a sharpened
end portion to facilitate in the insertion into the cushioning
media; however, this is not required. The hook is generally
designed such that the insertion section engages a bottom region
382 of the cushioning media so that the hook at least partially
supports the weight of the cushioning media at the bottom region of
the cushioning media when the cushioning media is positioned on the
upright side frame; however, this is not required. The insertion
section of the hook has a length such that when the insertion
section is inserted into the cushioning media, the insertion
section does not extend completely through the cushioning media;
however, this is not required. The hook includes a front transition
section 620 that connects the bottom of the insertion section to
the bottom of the intermediate section 630 of the hook. The front
transition section can have a curved shape; however, this is not
required. The intermediate section 630 of the hook is designed to
extend up along the back face 384 of the cushioning media.
Generally, at least a portion of the insertion section is generally
parallel to a portion of the intermediate section; however, this is
not required. The hook includes a back transition section 640 that
connects the top of the intermediate section of the hook to the top
of the arm section 650 of the hook. The back transition section can
be curved in shape; however, this is not required. The arm section
650 of the hook is designed to secure the hook to the glass
transportation cart. A portion of the arm section can include a
tension arrangement 660; however, this is not required. Generally,
the tension arrangement is positioned at or near the bottom end of
the arm section; however, this is not required. The tension
arrangement is generally designed to facilitate in maintaining the
hook on the glass transportation cart. As illustrated in FIG. 4,
the tension section is a bent portion on the end of the arm
section. The hook has a generally S-shape; however, this is not
required. Several non-limiting the alternative hook configurations
are illustrated in FIGS. 5-7.
[0103] Referring again to FIG. 4, a durable strip of material 670
(e.g., metal strip, plastic strip, etc.) is shown to be connected
to spacer bar 530 in a spaced relationship from the spacer bar so
that a gap 680 exists between the front face of the space bar and
the back face of the durable strip. The durable strip is shown to
be connected to the spacer bar by at least one screw 690; however,
it can be appreciated that the durable strip can be connected to
the spacer bar in other or additional ways. Gap 680 has a width to
allow the arm section of the hook to be inserted therein. The
tension arrangement 660 on the arm section is designed to be
slightly compressed in the gap so as to help secure the hook in the
gap. As illustrated in FIG. 4, the arm section is inserted in the
gap until the back transition section 640 engages the top of the
durable strip 670; however, this is not required. The hook enables
the cushioning media to be easily secured to the upright side frame
of the glass transportation cart. The hook also enables the
cushioning media to be easily removed from the upright side frame
of the glass transportation cart. As such, the replacement of the
cushioning media is significantly simplified by use of hook
600.
[0104] As mentioned above, additional non-limiting hook
configurations are illustrated in FIGS. 5-7. FIGS. 5 and 6 also
illustrate the use of hook 600 to secure the cushioning media to
the spacer bars on the main frame of a flat bed cart or a dual
frame cart. Although hook 600 can be used to secure the cushioning
media to the main frame of a flat bed cart or a dual frame cart,
the larger forces that are exerted by the glass panes, glass frame,
etc. that are situated on the main frame of the flat bed cart or a
dual frame cart can cause the cushioning media to potentially
prematurely release from the main frame.
[0105] Referring now to FIGS. 8 and 12-20, there is illustrated
another type of attachment arrangement that can be used to connect
a strip of cushioning media to a spacer bar on the upright side
frame of a dual frame cart, and/or a spacer bar on the main frame
of a dual frame cart or a flat bed cart. The connection arrangement
is in the form of a rail 700 that has a channel designed to at
least partially receive a portion of the cushioning media.
[0106] One of the major problems of most of the prior art
attachment arrangements for Homasote is that such attachment
arrangements provide only localized support to the strip of
Homasote. As such, the strip of Homasote is only held in localized
regions where the prior art fastener S (e.g., staple, nail, rivet,
etc.) are located. When a glass frame F is dragged over the surface
of the Homasote, as illustrated in FIGS. 9-11, the glass frame
shifts and/or vibrates. As such, during transport of the glass
frame on the cart, and/or when the glass frame is pulled off of
and/or is inserted onto the glass transportation cart, the movement
and vibration of the glass frame creates a bending moment on the
cushioning media as illustrated in FIGS. 12 and 13 11. This bending
moment eventually results in the shearing B of the Homasote at or
near the location of the prior art fastener S as illustrated in
FIG. 11, thereby resulting in the Homasote prematurely releasing
from and/or falling off the glass transportation cart.
[0107] The attachment arrangements disclosed in FIGS. 8 and 12-20
are designed to support at least a majority of the longitudinal
length of the cushioning media that is exposed to the glass panes,
glass frames, etc. glass panes, assembled glass units, IGUs, framed
glass, etc.; thereby inhibiting or preventing the shearing of the
cushioning media when glass panes, glass frames, etc. glass panes,
assembled glass units, IGUs, framed glass, etc. are insert and/or
removed from the glass transportation cart, and/or are transported
on the glass transportation cart.
[0108] Referring now to FIG. 8, the attachment arrangement is the
form of a rail 700 that includes a base 710 and two side walls 720,
730 that form a channel C. The channel has a generally U-shaped
configuration; however, this is not required. The size and shape of
the two side walls 720, 730 are generally the same along the
longitudinal length of the rail; however, this is not required. The
two side walls extend generally perpendicular to the plane of base
710; however, this is not required. The base is shown to be
generally flat; however, this is not required. The side walls are
also illustrated as planar; however, this is not required. The side
walls 720, 730 have a height that is less than the thickness of the
cushioning media 380 so that the top edge of each side wall is
positioned below the top surface 386 of the cushioning media when
the cushioning media is fully positioned in channel C. The spacing
of the inner surface 722, 732 of the two side walls from one
another can be less than the width of the cushioning media, equal
to the width of the cushioning media, and/or greater than the width
of the cushioning media along one or more portions of the
longitudinal length of rail 700. As illustrated in FIG. 8, the
spacing of the inner surface 722, 732 of the two side walls from
one another is slightly greater than the width of the cushioning
media.
[0109] The cushioning media can be secured in the channel of the
rail in a variety of ways (e.g., adhesive, friction connection,
mechanical connection, etc.). As illustrated in FIG. 8, a plurality
of teeth or barbs 740 are positioned on the top surface 712 of the
base. The barbs are used to inhibit movement of the cushioning
media in the channel. As can be appreciated, an adhesive can be
used in conjunction with the barbs to secure the cushioning media
in the channel; however, this is not required. The height of the
barbs is shown to be less than the height of the side walls and the
thickness of the cushioning media. The bottom surface 714 of the
base can be secured to the glass transportation cart and/or to
another material that is in turn is directed or indirectly
connected to the glass transportation cart in a variety of ways. As
illustrated in FIG. 8, the rail is shown to be directly connected
to the spacer bar.
[0110] Referring now to FIGS. 12-17, there is illustrated another
non-limiting configuration of the attachment arrangement in the
form of rail 700. Rail 700 includes a base 710 and two side walls
720, 730 that form a channel C. The two side walls 720, 730 have a
curved configuration that results in a generally C-shaped
configuration. Various types of C-shaped configurations can be used
for one or both side walls. The C-shaped configuration of the side
walls can be used to facilitate in better maintaining the
cushioning media in the channel of the rail 700. As illustrated in
FIGS. 12-14, the front edge of the side walls slightly penetrates
into the sides of the cushioning media, thereby securing the
cushioning media in channel C. As illustrated in FIGS. 15-17, when
the cushioning media is inserted into channel C, and the distance
between the top or front edges of the two side walls is less than
the width of the cushioning media. As such, the insertion of the
cushioning media into the channel will cause the one or more
C-shaped walls to slightly spring backward as illustrated by the
arrow in FIG. 16 to allow the cushioning media to be inserted into
the channel C. Once the cushioning media is inserted into the
channel, one or both of the C-shaped walls will attempt to spring
back as illustrated by the arrows in FIG. 17, thereby resulting in
the front edge of the C-shaped walls to dig slightly into one or
both sides of the cushioning media. The springing back of the one
or more C-shaped walls also creates a downward force on the
cushioning media to facilitate in causing the cushioning media to
move further into the channel C of rail 700. The front edge of the
C-shaped side walls also provides lateral support to the cushioning
media that is positioned in channel C. The design of the C-shaped
side walls allows the cushioning media to be pushed out from the
channel along the longitudinal axis of the channel when the
cushioning media needs to be replaced, yet inhibits or prevents the
cushioning media from being easily lifted out of the channel. Any
force applied to the cushioning media which tries to pull the
cushioning media up and out of the channel causes the front edges
of the C-shaped side walls to bite deeper into the side of the
cushioning media, thereby further preventing the cushioning media
from being lifted out from the channel.
[0111] FIG. 12 illustrates rail 700 being secured to a spacer bar
350 on the main frame of a flat bed cart or a dual frame cart. FIG.
13 illustrates rail 700 being secured to a spacer bar 530 on the
upright side frame of a dual frame cart. FIG. 14 illustrates rail
700 being mounted on a durable strip 670, which in turn is mounted
on a spacer bar 530 on the upright side frame of a dual frame cart.
As can be appreciated, FIGS. 12-14 illustrate non-limiting
arrangements for securing rail 700 to a glass transportation
cart.
[0112] Referring now to FIGS. 18 and 19, another configuration for
rail 700 is illustrated wherein side walls 720, 730 have a
different C-shaped configuration from the side walls illustrated in
FIGS. 12-17. As can be appreciated, side walls 720, 730 can have
other types of C-shaped configurations. The top surface 712 of base
710 includes a plurality of barbs 740. These barbs can have the
same or similar features as the barbs illustrated in FIG. 8;
however, this is not required. The barbs are illustrated as having
a three and two barb staggered pattern; however, it can be
appreciated that other barb patterns can be used. Base 710 includes
a connection opening 760 that can be used to secure the rail to
spacer bar 350 by a screw 750 and/or other type of mechanical
connector (e.g., rivet, nail, bolt, etc.).
[0113] Referring now to FIG. 20, another configuration for rail 700
is illustrated wherein side walls 720, 730 includes a plurality of
slots 770 so that the side walls are at least partially segmented
along the longitudinal length of the side walls. The one or more
slots, when used, allow the side walls to accommodate more
variation of width along the longitudinal length of the cushioning
media. The slots can have the same or different size, configuration
and/or spacing from one another. The slots on both side walls can
have the same or different size, configuration, spacing from one
another, and/or location along the length of the side wall;
however, this is not required.
[0114] It will thus be seen that the objects set forth above, among
those made apparent from the preceding description, are efficiently
attained, and since certain changes may be made in the
constructions set forth without departing from the spirit and scope
of the invention, it is intended that all matter contained in the
above description and shown in the accompanying drawings shall be
interpreted as illustrative and not in a limiting sense. The
invention has been described with reference to preferred and
alternate embodiments. Modifications and alterations will become
apparent to those skilled in the art upon reading and understanding
the detailed discussion of the invention provided herein. This
