Description
PRIORITY TO PENDING U.S. APPLICATION
[0001] This application claims priority to U.S. Provisional
Application 60/58,676 filing date Jul. 6, 2004, for the subject
matter contained therein.
FIELD OF THE INVENTION
[0002] The present invention relates to a device and method for
hanging and dispensing both spooled and non spooled products. In
particular, the present invention provides a device that a)
rotatingly engages a spool on first and second engagement means,
and provides a means for hanging the spool and distributing product
therefrom, and b) engages a container on first and second
engagement means and provides a means or hanging the container and
distributing product therefrom.
BACKGROUND OF THE INVENTION
[0003] Nails, screws, pins, clips and many other loose products are
shipped, stored, and distributed in containers such as bags, boxes,
buckets and pails. Flexible elongated products, such as wire,
tubing, rope, and chain, are commonly sold on spools made of rigid
material such as plastic, metal, or wood. Both loose and spooled
products are used extensively in building construction, automotive,
and many other industries. In the building industry alone, millions
of feet of electrical wire and millions of pounds of nails and
screws are dispensed each year. Problems associated with handling
and dispensing these products negatively impacts both safety and
productivity.
[0004] Spools can be heavy and difficult for a person to handle.
For example a single plastic spool of electrical wire can weigh
from twenty to one hundred fifty pounds or more. Many devices
currently exist to aid in dispensing such products from their
spools. Presently existing dispensing tools typically suspend the
spool from a shaft or axle which is inserted into a hole in the
center of the spool. The spool rotates about the shaft or axle as
product is pulled from the spool. However, suspending the spools
from a shaft presents safety and productivity problems that prior
art devices fail to overcome.
[0005] Many safety problems inherent in existing spooled product
dispensing designs can be demonstrated by examining U.S. Pat. No.
5,887,819 to Korn. The Korn patent shows the typical way in which
spooled products are supported for distribution: a wire spool rack
includes a left side member, a right side member, and a rod; the
ends of the rod are disposed in a slot defined in the left side
member, and a slot defined in the right side member; spools of
coiled wire are rotatingly mounted on the rod; more than one rod
may be mounted in the rack, and more or less than three spools may
be mounted on the rod(s). When distributing electrical wire four or
five spools are typically held on a single rod. To load or change
spools on the rods workers must support the weight of three or four
spools while loading another. This number of spools can weigh
hundreds of pounds, and often exceeds the maximum amount of weight
that can be safely handled by available manpower. Each time a spool
runs out of wire, each time a wire size needs to be changed, each
time a wire color needs to be changed, and each time the
distribution location needs to be changed, multiple spools need to
be unloaded and loaded on the rods.
[0006] The shape of a spool creates another safety problem which
prior art devices fail to overcome. While the spool shape may be
ideal for dispensing coiled products, it is less than ideal for a
worker to grip and carry. In order set up or change the
distribution location within a worksite, a worker must pick up each
individual spool of wire and carry it to the desired location. Each
time a worker carries an unsupported spool of wire he risks
physical injury. If a worker looses his grip on a spool and tries
to regain control he can easily suffer a muscular or skeletal
injury. If a spool falls on a worker's foot, a broken bone is
likely to occur. The primary way the prior art addresses the
problem of moving spools from one location to another is to adapt a
cart to carry spools of wire. U.S. Pat. No. 5,509,671 to Campbell
describes one such device wherein a cart includes racks for holding
spools. Each rack is sized to typically hold three of four spools.
Spools are secured to a main bracket by slipping a tube through
openings formed in the center of the spools. The spools and the
tube are then raised into position. The racks are releasably
secured to and selectively removable from the cart to enable the
spools on the racks to be carried to a site which is remote from
the cart. Devices such as that described by Campbell suffer from
many of the same safety disadvantages as U.S. Pat. No. 5,887,819 to
Korn described above: each time a spool runs out of wire, each time
a wire size needs to be changed, and each time a wire color needs
to be changed, an entire rack must be handled. A loaded rack can
easily exceed the amount of weight that can be safely handled with
available manpower. Additionally, a fully loaded cart can weigh six
hundred pounds or more, be unbalanced, unstable, and prone to
overturning. These problems make cart type spool carriers an
extreme safety hazard at any work site.
[0007] Devices which rely on a shaft to support multiple spools are
costly in terms of productivity. On devices such as U.S. Pat. No.
4,869,344 to Peterson, U.S. Pat. No. 5,887,819 to Korn, U.S. Pat.
No. 5,509,671 to Campbell and U.S. Pat. No. 4,533,091 to Knight,
multiple spools ride against one another on a single axle. Spools
tightly adjacent to each other on a single axle can lock together
making distribution difficult. The rate at which any individual
spool rotates will likely be different than the rotation rate of
any adjacent spool. When a heavy spool rotates faster than an
adjacent lighter spool, friction between the spools causes the
lighter spool to spin too fast. This can cause the product to loop
and tangle. Should excess wire become tangled about the axle, the
axle must be completely unloaded and reloaded to clear the problem.
Even when no problems occur, loading and unloading spools on shafts
is time consuming because multiple spools must be unloaded and
reloaded on a shaft whenever a single spool needs to be
changed.
[0008] Another productivity issue is related to spool breakage.
Spools are increasingly constructed of rigid plastic. When dropped
or banged these plastic spools tend to break. Most existing
distribution devices require the user to carry unsupported spools
of product to distribution locations. Because spools of wire are
heavy and difficult to handle they are frequently dropped and
broken. Spools are also frequently broken during transport to and
from a work site. Spools are typically transported in open bins in
the back of work trucks and vans. There is no way to position a
spool so that it will be stable during such transport. Existing
distribution tools do nothing to protect spools during transport.
Because wire can get hung up on broken spools entire spools of wire
are often discarded when the spool breaks. The cost of broken
spools adds significant expense to an electrician's overhead.
[0009] Another productivity related shortcoming of prior art
devices is that they provide no means of distributing wire in
multiple directions. In the building construction trade it is often
necessary to pull a long length of wire, such as romex wire, in one
direction from one location, and to later pull another length of
the same wire from the same location but in a different direction.
In order to change the direction of wire distribution on existing
devices, the spool must be unloaded, the distribution device
reoriented, and the spool reloaded on the device.
[0010] Workers frequently need to distribute wire, nails, screws,
and other products when working on a scaffold. In this situation
the worker is presented with a major safety problem. Loose products
such as nails and screws are typically distributed from containers
such as bags, boxes, buckets or pails which sit on the floor of the
scaffolding. Such containers create obstacles which the worker
might trip on, causing the products or the worker to fall from the
scaffold. There is currently no known product to keep nail, screw,
or other product packages secured off the scaffold floor.
[0011] When distributing wire from a scaffold, wire spools
typically remain on a distribution device on the ground. Wire is
then pulled up through the scaffold. Wire pulled in this manner is
prone to getting tangled in the scaffold, creating a danger to all
workers in the vicinity of the scaffold. Additionally, every time a
spool needs to be changed, the electrician must climb off the
scaffold, change the spools, and climb back up the scaffold. When
climbing up the scaffold, the electrician must pull the wire as he
climbs, creating an additional safety hazard. U.S. Pat. No.
6,688,550 to Mullins attempts to overcome problems associated with
pulling wire from remote locations by providing a portable supply
rack which is stabilized by hanging it at a desired work station.
The Mullins supply rack has at least one support rod having
opposite ends. Each of the opposite ends of the support rod is
insertable through corresponding aligned apertures in a pair of
side walls. Each of the opposite ends of the support rod includes
an aperture which receives a securing member such as a clip or pin
therein. In order to use such a device on a scaffold, the support
rod would have to be inserted through the center of a spool. The
support rod would then be mounted to the side walls of the supply
rack and the securing members secured to the support rod. The
supply rack would then be hung from the scaffold. This process
would create a safety hazard by causing the electrician to handle
pieces such as the support rod, securing members, supply rack, and
spool, while on the scaffold. If any one piece is dropped it
becomes a danger to those working below. If the supply rack is
loaded on the ground, its shape and weight would make it difficult
and dangerous to carry up the scaffold.
[0012] Space on any work vehicle is limited. Existing wire
distribution devices take up valuable space on these vehicles in
addition to the space that is used for the spools themselves.
Furthermore, current distribution devices are bulky and difficult
to handle and must be hauled to and from a work site.
[0013] It is therefore an object of the present invention to
provide a product hanger that overcomes the above mentioned
problems of prior art devices.
[0014] Another object of the present invention is to provide a
product hanger that allows distribution of product from a spool
without the use of a solid axle, shaft, or rod.
[0015] Another object of the present invention is to provide a
product hanger that is safe to use on scaffolding.
[0016] Another object of the present invention is to provide a
product hanger that provides omni-directional distribution from a

product hanger that can support a container.
[0018] Another object of the present invention is to provide a
product hanger that allows a single spool to be removed and
installed for distribution without removing and installing other
spools.
[0019] Another object of the present invention is to provide a
product hanger that can be safely handled, loaded, and unloaded by
a single person.
[0020] Another object of the present invention is to provide a
product hanger that provides a safe and convenient means for a
person to carry spools.
[0021] Another object of the present invention is to provide a
product hanger that protects spools during transport.
[0022] Another object of the present invention is to provide a

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0035] Referring now to the drawings where similar elements are
numbered the same, FIG. 1 depicts the product hanger 10 of the
present invention. The product hanger 10 comprises at least one
main support member 20 defining a longitudinal axis 11. The main
support member 20 comprises at least one hanging means 30 for
hanging the product hanger 10 from a support (not shown). A first
end 23 of the main support member 20 comprises a first vertical
support arm 40 which extends downwardly to a terminating end 43 of
the first vertical support arm 40. The terminating end 43 of the
first vertical support arm 40 comprises a first engagement member
60. A second end 25 of the main support member 20 comprises a
second vertical support arm 50 which extends downwardly to a
terminating end 53 of the second vertical support arm 50. The
terminating end 53 of the second vertical support arm 50 comprises
a second engagement member 70. The first and second engagement
members are designed to engage and support a product to be held
between the vertical support arms 40, 50 and may be any engagement
members known to those of average skill in the art.
[0036] In one embodiment of the invention, the two engagement
members 60, 70 engage a hole that resides in the center of a spool
without the need for a shaft or axle running through the center of
the spool. The spools are mounted and dismounted from the product
hanger 10 by flexing the vertical support arms 40, 50, sliding them
over the spools until the two engagement members 60, 70 are
adjacent to two ends of the hole disposed in the center of the
spool, and releasing the vertical support arms 40, 50 so that the
two engagement means 60, 70 enter the hole to engage the spool.
Alternatively, as seen in FIG. 2, a length of pipe or tubing 24 may
be inserted through the hole in the center of the spool, and
engaged by the two engagement members 60, 70. This is useful to
engage a spool that would otherwise be too narrow be engaged by the
two engagement members 60, 70. Because the hanger 10 hangs a single
spool, individual spools may be removed and replaced from within a
series of adjacent spools without removing any spools except the
one being changed, something impossible to accomplish using prior
art devices.
[0037] The hanging means 30 is any hanging means known to those of
average skill in the art, such as a closed loop section of the main
support member 20. A closed loop is used, for example, for
transporting large heavy spools: a pipe or rod is inserted through
the closed loop and one or more persons carry each end of the pipe
or rod. In a preferred embodiment of the invention as shown in FIG.
5, the hanging means 30 includes a rotating joint 31 which is any
rotating joint known to those of average skill in the art. The
rotating joint 31 is operable to allow the main support member 20
to rotate 360 degrees in relation to a support from which the
product hanger 10 is hung. A rotating hanging means is used, for
example, for hanging an individual spool of wire for omni
directional dispensing of the wire. The invention includes a
product guide 41 to facilitate omni directional rotation of the
product hanger by initiating rotation of the main support member
20. The product guide comprises at least one guide arm 42 pivotally
attached to the main support member 20. The guide arm 42 comprises
a guide opening 43 through which product being dispensed from the
spool is pulled. The lateral force of the product against the guide
opening initiates rotation of the main support member 20 about an
axis 44.
[0038] In a most preferred embodiment of the invention as shown in
FIGS. 2 and 3, the main support member 20 comprises a first hanging
means 21 and a second hanging means 22. The main support member 20,
the first and second hanging means 21, 22, the vertical support
arms 40, 50, and the first and second engagement members 60, 70 are
formed from a single length of rigid material. The first and second
hanging means 21, 22 are arcuately formed sections of the first and
second ends 23, 25 of the main support member 20 forming a
substantially identical pair of hooks extending perpendicular to
and from opposite ends of the longitudinal axis 11. The first and
second hanging means 21, 22 extend into the first and second
vertical support arms 40, 50. The first and second vertical support
arms 40, 50, are thus integral extensions of the first and second
hanging means 21, 22.
[0039] The open hook hanging means as shown in FIGS. 2-4 are
particularly useful in hanging a series of spools for distribution
from a single axle. In the construction trade, wire is generally
distributed off of four or five spools hung on a single axle. On
existing devices, a single axle runs through the center of the
spools necessitating the removal of several spools to change a
single spool. With the present invention, the product hanger is
mounted to an individual spool, and then hung from a support.
Because the hanging means can fit over a support which is too big
to pass through the center of a spool, stronger supports can be
used than previously possible. This prevents the support from
sagging, thus keeping the spools from binding and locking together.
The open hook hanging means also provides an alternative method of
changing an individual spool hanging adjacent to other spools on a
single axle. The product hanger is unhooked from the axle together
with the individual spool, the spool is changed, and the product
hanger is then hung back on the axle with the new spool in place.
Changing an individual spool hanging adjacent to other spools on a
single axle, without disturbing the other spools, is something
impossible to accomplish using existing devices.
[0040] FIG. 4 shows a most preferred embodiment of the present
invention wherein a first spacing means 100 and a second spacing
means 200 position the spools at an operable distance from adjacent
spools. In a most preferred embodiment of the invention, the first
and second spacing means 100, 200, are comprised of upper ends 110,
210 of the first and second vertical support arms 40, 50. This is
preferably accomplished by forming the first and second vertical
support arms 40, 50 to angle in towards each other. This angle will
vary depending on the length of the vertical support arms 40, 50,
and is easily determinable by those of average skill in the art
without the need of excessive experimentation. Alternatively, the
first and second spacing means 100, 200, may be formed into the
main support member or the first and second hanging means 21, 22
(FIG. 2).
[0041] Referring back to FIG. 1, the first and second engagement
members 60, 70 angle in towards each other. In one embodiment of
the invention, the first and second engagement member s 60, 70 form
an angle of between about 90 degrees and 45 degrees with respect to
the first and second vertical support arms 40, 50. In a preferred
embodiment of the invention, the first and second engagement member
s 60, 70 form an angle of about 70 degrees with respect to the
first and second vertical support arms 40, 50. The angle of the
engagement member s keeps the spool in place by engaging a lip on
the inside of the hole that extends through the spool. The shape
and angle of the engagement member s varies depending on the shape
of the spool, and will be easily discoverable by those of average
skill in the art. In another preferred embodiment of the invention
the first and second engagement member s 60, 70 are integral
extensions of the first and second vertical support arms 40, 50,
for example, if the first and second vertical support arms 40, 50
are formed of bent wire, the wire at the end of each support arm
40, 50 is bent in towards the other to form the engagement means
60, 70. For securely holding spools in place it is useful to form
the engagement means 60, 70 into a loop 61 (FIG. 2).
Experimentation has shown that the loop design is best suited for
keeping spools in place. The exact size and design of the loop
varies depending on spool design, and is easily discoverable by
those of ordinary skill in the art without undue experimentation.
In yet another preferred embodiment of the invention, the first and
second engagement members 60, 70 are rollers 71 (FIG. 6) rotatingly
attached to the first and second vertical support arms 40, 50. The
rollers 60, 70 are preferably angled as shown in FIG. 6 to help
keep the spools in place.
[0042] The product hanger of the present invention is constructed
of rigid material such as metal, pot metal, metal alloy, steel,
stainless steel, spring steel, steel wire, extruded plastic, and/or
pvc. The preferred material is spring steel or extruded plastic. In
a preferred embodiment of the present invention as shown in FIG. 2,
the main support member 20, the first and second hanging means 21,
22, the first and second vertical support arms 40, 50, and the
first and second engagement member s 60, 70, are formed from a
single piece of rigid material. In an alternative embodiment of the
present invention, the distance between the first vertical support
arm 40 and the second vertical support arm 50 is adjustable. As
shown in FIG. 6, a sectional main support member 300 provides an
adjustable distance between the first vertical support arms 40 and
the second vertical support arm (not shown). The sectional main
support member 300 is any sectional support member known to those
of average skill in the art, and preferably is a male section 320
which slides into a female section 310 and is secured by at least
one set screw 330. Other adjustable members contemplated by this
invention are track and slider type members.
[0043] In yet another preferred embodiment of the invention as
depicted in FIG. 7, the product hanger 10 is adapted to support a
container 400. The first and second engagement members 60 are
adapted to engage the container 400. The engagement members 60
engage the container by any means that would be known by a person
of average skill in the art. In one embodiment the engagement
members 60 point towards each other and form an angle of
approximately 90 degrees in relation to their respective vertical
support arms 50. The container may be any pail or bucket known to
those of average skill in the art, and preferably comprises first
and second channels 410, 415 vertically disposed in opposing
sidewalls of the container 400. The channels 410, 415 are adapted
to engage the vertical support arms 40, 50. A bottom section 420 of
the container 400 is any shape which would be consistent with the
container 400 being secured in the product hanger 10. In a
preferred embodiment the bottom section 420 comprises a
substantially flat surface. In a most preferred embodiment, the
bottom section 420 comprises at least one channel disposed therein
to engage the engagement members 60.
