Abstract
A system is disclosed for facilitating rotation of a mattress in
a horizontal plane carried by a box spring or a platform. In order
to facilitate rotation, slick surfaces between the mattress and the
box spring or platform are selectively placed in engagement with
each other, in one embodiment of the invention. The slick surfaces
may be provided by two (2) separate covers; one cover for the
mattress and one cover for the box spring, platform or bed skirt.
One cover is provided with a slick and non-slick surface. The other
cover may be the same as the first cover or may have sock surfaces
on two sides. In an alternate embodiment of the invention, one of
the covers may be provided as a protective cover that encapsulates
the entire mattress. In another alternate embodiment, one cover may
be provided that cooperates with a suck surface that is integrally
provided on one or the other of the mattress or box spring or
platform. In yet another alternate embodiment of the invention,
slick surfaces may be provided on both the mattress and the box
spring or platform. In this embodiment, in order to prevent
movement of the mattress with respect to the box spring or
platform, the mattress is secured relative to the box spring or

(hereinafter "mattress") may be placed on to of the box spring or
alternatively placed upon a platform forming a platform bed. In
both applications, the mattress is held in place by friction and
its weight.
[0005] Various types of mattresses are known. For example, U.S.
Pat. Nos. 7,617,556 and 7,644,671 disclose conventional mattresses.
Such conventional mattresses it a "casing" which is formed from
material for holding the internal components of the mattress. The
casing includes a bottom panel and four (4) vertical panels
connected to the periphery of the bottom panel forming an open top
container. In one such conventional mattress, a spring core is
disposed in the container and rests against the bottom floor and
fits snugly against the vertical panels. One or more layers of foam
padding is placed on top of the spring core and covered with a top
cover which is secured to the vertical panels.
[0006] In other known mattresses, a foam core is used in place of
the spring core. Other known mattresses are known to include a
so-called "pillow-top". The pillow top is generally formed as a
comforter secured to the top cover and filled with cotton or some
type of fibrous material.
[0007] A problem with the various types of mattresses, as discussed
above, is that over time the mattress materials lose their
resiliency causing body depressions to develop. In order to even
out the wear in the mattress, it is known to rotate the mattress in
the horizontal plane to relocate the body depressions, as shown for
example, in FIGS. 1 and 2. Depending on the size of the mattress,
one or two people may be required to rotate the mattress. For
example, king and queen size mattresses may likely require two
people to rotate the mattress, as shown in FIG. 1, while full and
twin size mattresses can likely be rotated by a single person, as
shown in FIG. 2.
[0008] Mattresses are relatively heavy items. The weight of a
mattress varies as a function of the coil core, the gauge of the
coil and the type of foam material used. An average king size
mattress weighs between 85 and 115 pounds. High end king size
mattresses with latex or memory foam can weigh as much as 300
pounds (http://www.mattressdirectonline.com).
[0009] In order to rotate a mattress, the mattress must first be
lifted and then rotated, As such, rotating a mattress is hard work.
Depending on the weight of the mattress, rotating a mattress can be
virtually impossible for some people, such as senior citizens, as
well as people that are handicapped or disabled and others.
[0010] In order to address this problem, mattresses with removable
pillow tops have been developed. An example of such a mattress is
disclosed in U.S. Pat. No. 5,414,882. The '882 patent discloses a
mattress with a pillow top that is secured to the top cover of the
mattress by way of a zipper. With such a configuration, the pillow
top can be relatively easily rotated by unzipping the pillow top,
rotating it and zipping the pillow top back in place. While such a
configuration enables body depressions in the pillow top to be
relocated, it has no affect on body depressions that result in the
mattress itself. Thus there is a need for a system to facilitate
rotation of a mattress.
SUMMARY OF THE INVENTION
[0011] Briefly, the present invention relates to a system for
facilitating rotation of a mattress in a horizontal plane carried
by a box spring or a platform. In order to facilitate rotation,
slick surfaces between the mattress and the box spring or platform
are selectively placed in engagement with each other. In one
embodiment of the invention, the slick surfaces may be provided by
two (2) separate covers; one for the mattress and one for the box
spring or platform. One cover is provided with a slick and
non-slick surface. The other cover is provided with at least one
slick side and may have two slick sides. In an alternate
embodiment, one cover may be a protective cover that encapsulates
the entire mattress and permanently exposes a slick surface
relative to the box spring or platform. Alternatively, one cover
may be provided that cooperates with a slick surface that is
integrally provided on one or the other of the mattress or box
spring or platform. In an alternate embodiment of the invention,
slick surfaces may be provided on both the mattress and the box
spring or platform. In this embodiment, in order, to prevent
movement of the mattress with respect to the box spring or
platform, the mattress is secured relative to the box spring or
platform by removable fasteners in a normal mode of operation.

DETAILED DESCRIPTION
[0040] The present invention relates to system for facilitating
rotation of a top mattress in a horizontal plane. In general, slick
surfaces between the mattress and the box spring or platform are
selectively placed in engagement with each other. In particular,
the invention relies on a reduced friction co-efficient between the
box spring or platform and the mattress to facilitate rotation of
the mattress in a horizontal plane. In one embodiment of the
invention, as illustrated in FIGS. 3-11, the slick surfaces may be
provided by two (2) separate covers; one cover for the mattress and
one cover for the box spring or platform. One cover is provided
with a suck and non-slick side. The other cover is provided with at
least one suck side and may have two suck sides. In an alternate
embodiment, as shown in FIGS. 21 and 22, one cover may be a
protective cover that encapsulates the entire mattress and
permanently exposes a slick surface relative to the box spring or
platform. In another alternate embodiment, one cover may be
provided that cooperates with a slick surface that is integrally
provided on one or the other of the mattress or box spring or
platform. In yet another alternate embodiment of the invention, as
shown in FIGS. 12-20, slick surfaces may be provided on both the
mattress and the box spring or platform. In this embodiment, in
order to prevent movement of the mattress with respect to the box
spring or platform, the mattress is secured relative to the box
spring or platform by removable fasteners in a normal mode of
operation.
[0041] in the embodiments illustrated in FIGS. 3-11 and 21-22, two
(2) covers are provided which enable slick surfaces between the
mattress and the box spring or platform to be selectively placed in
contact with each other to reduce the normal friction therebetween
to enable the mattress to be rotated in a horizontal plane without
lifting the mattress. Alternate embodiments, operate on the same
principle but require only one separate cover that cooperates with
a slick surface integrated into one or the other of the mattress or
box spring or mattress. In yet other embodiments of the invention,
as illustrated in FIGS. 13-20, the slick surfaces on the mattress
and box spring or platform are constantly in engagement with each
other when the mattress is placed on top of the box spring or
platform. In these embodiments, one or more fasteners are used to
secure the mattress to the box spring or platform to prevent
unintended movement therebetween in a normal mode of operation.
[0042] Referring first to FIGS. 3-5, the invention comprises a
first cover 20 and a second cover 22. The covers 20 and 22 each
include a rectangular panel 24 and 26, respectively, configured to
the size of a mattress 28 and a box spring 30. Each of the covers
20, 22 includes a stretchable band 32, 34, attached to the
periphery of the panels 24, 26 respectively. The bands 32, 34,
allow the covers 20, 22 be removably secured to the mattress 28 and
the box spring 30, as generally shown in FIG. 4.
[0043] The bands 32, 34 may be formed from an elastic material, for
example, spandex and other stretchable materials, such as mesh or
an elastic banding and attached to the panels 24, 26 respectively,
for example, by sewing. Alternatively, the bands 32, 34 can be
formed from a mesh or stretchable fabric. The bands 32, 34 can be
formed from the same material as the panels 24, 26 and secured to
the mattress 28 and box spring or platform 30 by way of a
drawstring (not shown) or other attachment method.
[0044] The bands 32 and 34 may also be formed by less labor
intensive methods, as illustrated in FIGS. 23a-23b and FIGS.
24a-24c The methods illustrated in these figures, reduce the amount
of sewing and thus the labor involved. For simplicity, only one
cover 20 is described and illustrated. Referring first to FIGS. 23a
and 23b, one corner of a cover blank, generally identified with the
reference numeral 21, is illustrated for simplicity. The cover
blank is formed as a generally rectangular piece of material with
fold lines, generally identified with the reference numeral 23,
adjacent to each edge of the rectangular piece of material. As
shown in FIG. 23a, a piece of material is cut out of each corner
defining, for example, an obtuse angle. The cut-out is identified
with the reference numeral 25. The bands 32' are folded down as
shown in FIG. 23b. A piece of flexible material, such as elastic,
identified with the reference number 27, is used to bridge the
cut-out 25. The flexible material 27 is secured to the ends of the
contiguous bands 32'. As will be appreciated by those of ordinary
skill in the art, the embodiment illustrated in FIGS. 23a and 23b
significantly reduces the labor costs.
[0045] A second technique to reduce labor costs is illustrated in
FIGS. 24a-24c. In this embodiment, the corners of the material
blank 21' are cut to form a cut-out 25' that is not an obtuse
angle. The exemplary cut-out 25' is shown at roughly a 90 degree
angle. In this embodiment, a fastener strip 29 is affixed to each
end of the band 32'', adjacent the cut-out 25'. A cooperating
removable fastener strip 31 may be attached to the fastener strips
29 to secure the adjacent bands 32'' together. The fastener strips
29 and 31 may be Velcro or other type of fastener. The embodiment
illustrated in FIGS. 24a-24c allows the material blank 21' to be
juxtaposed over the mattress 28 or box spring 30 with the removable
fastener strips 31, as least partially removed for example, as
shown in FIG. 24b. and secured to the exposed cooperating fastener
strip 29, once the cover 20 is in place, as shown in FIG. 24c.
[0046] In accordance with an important aspect of the invention, one
cover 20, 22 has a "slick" side having a relatively low
co-efficient of friction and a non-slick side having a relatively
higher co-efficient of friction. The other cover 20, 22 has at
least one slick side and may have two slick sides. As such, when
the slick surfaces of the two covers 20, 22 are selectively placed
in contact with each other, the mattress 28 can be rotated in a
horizontal plane with minimal effort by one person in a
configuration defining a rotate mode of operation, as discussed in
more detail below. The non-slick side is used to selectively be
placed in contact with an uncovered surface of the mattress 28 or
an uncovered surface of the box spring 30 or platform or bed skirt.
The non-slick side provides a relatively high co-efficient of
friction when in contact with either an uncovered surface of the
box spring 30 or an uncovered surface of the mattress 28 or bed
skirt (FIG. 6) or platform (FIG. 12) in order to reduce if not
prevent unintended rotation of the mattress in a normal
configuration.
[0047] Various materials, such as cloth, and other materials that
are bendable and amenable to being folded and stored in relatively
small packages, are suitable for the panels 24, 26 for the covers
20, 22. The material for one cover 20, 22 need only have a slick
side and a non-slick side. The non-slick side can be created on one
side of a slick material by way of a coating or sewing or fusing a
non-slick backing to one side of the non-slick material Various
conventionally available materials are suitable for the cover
having a slick side and a non-slick side. For example, "20 Denier
Heat Sealable (backside) 100% Nylon Rip Stop" material is suitable
for use with the present invention or other materials with similar
coefficients of friction on the slick and non-slick sides. Such
material may be nylon, for example, 100% nylon with a coating on
one side, for example, urethane or other thermal plastic or heat
sealable coating Such nylon rip stop material is known to come in
widths of 58-62 inches wide and weighs about 1.9 to 4.4 ounces per
square yard. Such material can easily be pieced together to
accommodate various mattress widths if necessary.
[0048] Nylon rip stop material suitable for use with the--present
invention is available from various sources, such as, Quest
Outfitters of Sarasota, Fla. (http://questoutfifters.com). Their
nylon taffeta material is described in detail at
http://questoutfitters.com/coated.html#HEAT SEALABLE, hereby
incorporated by reference. Suitable nylon taffeta material is also
available from Rockywoods in Loveland, Colo.
(http://www.rockywoods.com). Their nylon taffeta material is
described in detail at
http://www.rockywoods.com/Fabrics-Hardware-Patterns-Kits/Medium-
-Weight-Nylon-Fabrics/Heat-Sealable-70-Denier-Nylon-Taffeta, hereby
incorporated by reference.
[0049] Non-woven materials may also be used for the cover 20, 22
having a slick side and a non-slick side. For, example, Tyvek.RTM.
polyethylene non-woven fabric, as manufactured by the DuPont
Corporation and described in detail at
http://www2.duponts.com/Products and Services/en VN/nwn.html may be
used. Other materials having two slick sides can also be used, such
as, silicone impregnated nylon rip stop, for example, as available
from Seattle Fabrics, Inc.,
http://www.seattlefabrics.com/nylons/html. Other materials can also
be used with a coating applied to one side. Moreover, different
materials can be used for each cover in an application.
[0050] Referring to FIG. 4, a first cover 20 is attached to the
underside mattress 28 so that its non-slick side is in contact with
the mattress 28 and its slick side is facing downwardly. Similarly,
the cover 22 is attached to the box spring 30 so that its non-slick
side is in contact with the box spring 30 and its sack side is
facing upwardly. Alternatively, the covers 20, 22 may be provided
with two slick sides In such an embodiment, one slick side is in
contact with the mattress 28, box spring 30, respectively, and the
other slick side is facing downwardly or upwardly, respectively.
When the mattress 28 is then brought into contact with the box
spring 30, as generally illustrated in FIG. 5, the slick sides of
the covers 20 and 22 will be in contact with each other, enabling
the mattress 28 to be rotated in a horizontal position with reduced
effort by a single person defining a rotate mode of operation.
[0051] Once the mattress 28 has been rotated and is in the desired
position, the top cover 20 may be detached from the mattress 28 and
attached to the box spring 30 over the cover 22. This places the
non-slick side of the cover 20 in contact with an uncovered surface
of the mattress 28, thereby reducing unintended rotation of the
mattress 28 with respect to the box spring 30. In this
configuration, both covers 20 and 22 are attached to the box spring
30.Alternatively, in embodiments in which each of the covers has a
suck side and a non-suck side, once the mattress 28 is in the
desired position, the bottom cover 22 can be detached from the box
spring 30 and attached to the mattress 28 over the cover 20,
exposing the non-suck side of the cover 22 to the box spring 30. In
this configuration, both covers 20 and 22 are attached to the
mattress 30.
[0052] FIGS. 6-8 illustrate operation of the covers 20 and 22 in an
application in which a bed skirt 36 is draped over the box spring
30, as generally shown in FIG. 6. Heretofore rotation of a mattress
28 with a bed skirt 36 draped over the box spring 30 was a
relatively cumbersome task. The present invention greatly
simplifies rotation of the mattress 28 in such an application while
keeping the bed skirt 36 in place.
[0053] More specifically, in this application, the first cover 20
is attached to the underside of the mattress 28 so that its slick
side is facing downward and its non-slick side (or alternatively
its second slick side) is in contact with the mattress 28. The
second cover 22 is attached to the box spring 30 over the bed skirt
36 so that its non-slick side is in contact with the bed skirt 36
and its slick side is facing upward, thereby placing the slick
sides of the covers 20 and 22 in contact with each other, as shown
in FIG. 7. The mattress 28 can then be rotated with reduced effort,
as generally illustrated in FIG. 12. After the mattress 28 is
rotated to the desired position, the cover 22 is detached from the
box spring 30 and attached to the mattress 28 over the cover 20, as
shown in FIG. 8. This places the non-slick &de of the cover 22
in contact with the bed skirt 36 to reduce if not prevent
unintended rotation of the mattress 28. As shown in FIG. 8, the bed
skirt 36 is uncovered and undisturbed since the cover 22 holds the
bed skirt 36 in place during the rotation of the mattress 28.
[0054] FIGS. 9-11 are similar to FIGS. 6-8 and illustrate another
application in which the bed skirt is used to hide the first and
second covers 20 and 22 in a normal configuration. Referring to
FIG. 9, the bed skirt 36 is disposed around the mattress 28 so that
its finished side is in contact with the mattress 28 and its
unfinished side is facing outwardly. The first cover 20 is attached
to the mattress 28 over the bed skirt 36 so that its non-slick side
is in contact with the bed skirt 36 and its slick side is facing
downwardly. The second cover 22 is attached to the box spring 30 so
that its non-slick side is in contact with the box spring 30 and
its slick side is facing upwardly, thus placing the slick sides of
the first and second covers 20 and 22 in contact with each other.
The mattress 28 can then be rotated in a horizontal plane virtually
effortlessly by one person. Once the mattress 28 is in the desired
position, the first cover 20 is detached from the mattress 28 and
attached to the box spring 30, over the second cover 22, as shown
in FIGS. 10 and 11. This places the non-slick side of the first
cover 20 in contact with the mattress 28, thereby reducing
unintended rotation of the mattress 28. Once the first cover 20 is
attached to the box spring 30, the bed skirt 36 is folded down over
the box spring 30, thereby hiding both the first and second covers
20 and 22, as shown in FIGS. 10 and 11.
[0055] FIGS. 21 and 22 illustrate an embodiment in which the first
cover is replaced with a protective cover 40, such as a protective
cover, that encapsulates the mattress 28. The protective cover 40
is to size and shape of the mattress 28 to provide a relatively
snug fit. An opening 42 is provided along one edge of the
protective cover 40 to enable the mattress 28 to be placed inside
the protective cover 40. A conventional fastener, such as a zipper
44 may be used to dose the opening 42. In this embodiment, one
surface 46 of the cover 40 is provided with a slick surface 46. The
mattress 28 and cover 40 is configured so that the slick surface 46
faces the box spring 30. The slick surface 46 of the cover 40
cooperates with the cover 22 attached to the box spring 30 to
facilitate rotation of the covered mattress 28 in a rotate mode.
The cover 22 is as described above with a slick surface and a
non-slick surface. More particularly, in a rotate mode of
operation, the cover 22 is attached to the box spring 30 so that
its non-slick surface is in contact with the box spring 30 and the
slick surface faces upwardly in order to contact the slick surface
of the protective cover 40. In this mode, the mattress 28 can be
rotated with reduced effort in a horizontal plane. Once the
mattress 28 has been rotated to the desired position, the cover 22
is attached to the mattress 28 causing its non-slick surface to be
in contact with the box spring 30.
[0056] In addition to the embodiments discussed above which require
two covers, alternate embodiments are discussed below which require
only one cover. For example, one of the covers 20, 22 may be
eliminated and a slick surface incorporated into the mattress 28 or
box spring 30. For discussion, assume that the box spring 30
includes an integral suck surface facing upwardly and is configured
to contact the mattress 28. In this embodiment, a cover 20 as
described above is attached to the underside of the mattress 28
such that the slick surface faces downwardly and the non-slick
surface is in contact with the underside of the mattress 28. In a
rotate mode of operation, the slick surface of the cover 20 is in
contact with the slick surface integrally formed in the box spring
30. Once the mattress 28 is rotated and in the desired location,
the cover 20 is attached to the box spring 30 so that the two slick
surfaces are in contact with each other and the non-slick surface
is in contact with underside of the mattress 28 defining a normal
mode of operation.
[0057] The embodiments discussed above are based on the use of one
or more covers which can be selectively configured in a rotate mode
of operation or alternatively a normal mode of operation. In the
embodiments illustrated in FIGS. 13-20, there are no covers. In
these embodiments, slick surfaces 50 and 52 are integrally provided
on the mattress 28 and box spring 30, respectively. In particular,
as best shown in FIG. 13, the mattress 28 is formed with an
integral slick surface 50 on it is underside. Similarly, the box
spring 30 can be formed with integral slick surface 52 facing
upwardly. As such, when the mattress 28 is properly placed on the
box spring 30, the slick surfaces 50 and 52 are in contact with
each other. In such a configuration, the mattress 28 can be freely
rotated with respect to the box spring 30.
[0058] In order to prevent movement of the mattress 28 with respect
to the box spring 30 in a normal mode of operation, fastener
systems, for example, Velcro fasteners, may be provided on the
corners of both the mattress 28 and the box spring 30. In
particular, permanent fastener strips 54 are provided on the
corners of the mattress 28, as shown in FIGS. 13, 14 and 16.
Similarly, permanent fastener strips 56 are provided on the corners
of the box spring 30. As shown in FIGS. 13, 4 and 16, when the
mattress 28 is correctly aligned with the box spring 30, the
permanent fastener strips 54 are aligned with the permanent
fastener strips 56. In order to secure the mattress 28 relative to
the box spring 30, removable cooperating fastener strips 58 are
selectively attached to the permanent fastener strips 54 and 56 as
shown in FIGS. 15 and 17 defining a normal mode of operation. The
removable fastener strips 58 are simply removed in order to rotate
the mattress 28 and replaced once the mattress 28 has been
rotated.
[0059] Two alternate embodiments are illustrated in FIGS. 18-20. In
the embodiment illustrated in FIGS. 18 and 19, permanent fastener
strips 60 and 62 are located around the peripheries of the mattress
28 and the box spring 30, adjacent to the edges where the mattress
28 and the box spring 30 come together, as shown in FIG. 18. As
shown in FIG. 19, a cooperating removable fastener strip 64 is
attached to the permanent fastener strips 60 and 62 on the mattress
28 and box spring 30, respectively. In yet another alternate
embodiment as shown in FIG. 20, the cooperating removable fastener
strip 64 may be affixed to the inside of a bed skirt 66. With such
a configuration, not only are the mattress 28 and box spring 30
secured together, the configuration also allows a bed skirt 66 to
be easily installed.
[0060] Obviously, many modifications and variations of the present
invention are possible in light of the above teachings. For
example, for relatively light weight mattresses, a single cover can
be used with either two (2) slick sides or one slick side and one
non-slick side. In such an embodiment, the invention relies on the
inherent surface roughness of either the mattress 28 or box spring
30. In an embodiment with a cover having two suck surfaces, the
cover is attached to either the mattress 28 or the box spring 30
and remains in place during both a rotate mode and a normal mode.
In an embodiment of the invention with a cover having a slick side
and a non-slick side, the cover is attached to either the mattress
28 or the box spring 30 so that the slick side faces outwardly and
contacts the other of mattress 28 or the box spring 30 in a rotate
mode of operation. In a normal mode of operation, the cover is
attached to the other of the mattress 28 or the box spring 30 so
that its non-slick side faces outwardly and contacts the inherent
surface roughness of the mattress 28 or the box spring 30. Thus, it
is to be understood that, within the scope of the appended claims,
the invention may be practiced otherwise than as specifically
described above.
