Abstract
Description
- This application claims the benefit of the filing date of Chinese Patent Application No. 200720119852.8, filed on Apr. 30, 2007.
- The present invention relates to a foldable piece of furniture, and more particularly to an ottoman or footstool that can be readily disassembled and collapsed.
- A variety of shapes and sizes of furniture, and in particular ottomans, footstools, and the like, have been developed over the years to provide comfort and decoration. Many consumers prefer furniture that is relatively inexpensive, multi-functional, easy to assemble, and easy to store and transport.
- For those consumers who cannot afford many pieces of furniture, it is desirable to have furniture which can perform multiple functions. Although the primary function of an ottoman is as a footstool, it is desirable to have an ottoman that can serve additional functions, such as providing storage space.
- Consumers expect furniture that is already assembled or can be easily assembled. Once assembled, however, most furniture cannot be easily disassembled. Most furniture is assembled using nails, screws, staples, epoxy, or some other type of relatively permanent fastener or fastening mechanism. This presents a challenge for consumers, especially when the furniture needs to be stored or transported from one location to another.
- Shipping and packaging costs can substantially increase the cost of furniture to the consumer. In particular, an assembled piece of furniture typically has a non-solid shape that takes up a large amount of space during shipping and makes it difficult to maximize the space utilized in a truck or transport vehicle. The same physical features of furniture can make it difficult for a consumer to store and transport from location to location, for example when moving residences.
- Accordingly, it is an object of the present invention to provide an ottoman wherein the top cover is conveniently removable to access an interior storage space. It is another object of the present invention to provide an ottoman that is easily assembled and disassembled using only basic hand tools. It is yet another object of the present invention to provide an ottoman that can be collapsed into an efficient and small package for transport and storage.
- The present invention provides a foldable ottoman having a sidewall assembly, a bottom panel, and a top lid. The sidewall assembly comprises a number of sidewalls and a number of hinges, preferably an equal number, each hinge interconnecting adjacent sidewalls, enabling the sidewall assembly to be moved between a collapsed state and a deployed state. The sidewall assembly has a bottom end and a top end, and a plurality of support members disposed near the bottom end. The bottom panel is preferably removably supported within the sidewall assembly by the support members, and the top lid is preferably removably supported by the top end of the sidewall assembly. The foldable ottoman can have various geometric shapes, including any polygon, such as a square, rectangle, hexagon, octagon, or higher, or can have a large number of sides so as to simulate a circle.
- The present invention also provides a method of assembling a foldable ottoman having a sidewall assembly, a bottom panel, a top lid, and plurality of support members. The sidewall assembly has a number of sidewalls interconnected by flexible hinges, and is moved from a collapsed state to a deployed state by pivoting the adjacent sidewalls about the flexible hinges into the desired geometric shape corresponding to the number of sidewalls. The support members are removably installed near a bottom end of the sidewall assembly, the bottom panel is inserted into an interior space within the sidewall assembly to be removably supported by the support members, and the top lid is placed onto a top end of the sidewall assembly to be supported thereon.
- Other objects, advantages, and features of the present invention will become apparent to those skilled in the art upon reading the following detailed description, when considered in conjunction with the appended claims and the accompanying drawings briefly described below.
- The accompanying drawings, which are incorporated herein and constitute a part of this specification, illustrate preferred embodiments of the invention, and together with the general description given above and the detailed description given below, serve to explain features of the invention. However, it should be understood that this invention is not limited to the precise arrangements and instrumentalities shown in the drawings.

- As shown in
FIGS. 1 and 2 , an ottoman 10 comprises asidewall assembly 20, abottom panel 30, and atop lid 40. Thesidewall assembly 20 is adapted to be moved from a collapsed state to a deployed state, and comprises a plurality ofsidewalls 22. Eachsidewall 22 has aninner face 26, anouter face 28, abottom end 50, and atop end 52.Adjacent sidewalls 22 are hingedly interconnected to each other usinghinges 24, ahinge 24 being disposed between each pair ofadjacent sidewalls 22. Eachhinge 24 preferably has an operating range of at least approximately 90 degrees, and eachhinge 24 more preferably has an operating range of at least approximately 180 degrees. - In an example, as depicted in
FIG. 3A , a hinge 24 a can be adapted to flex between about 0 degrees, to enable a pair ofadjacent sidewalls 22 to be oriented such that the twosidewalls 22 are disposed substantially parallel to each other and aligned in the same plane, and about 90 degrees, to enable the pair ofadjacent sidewalls 22 to be oriented perpendicularly to each other. Further, a hinge 24 b can be adapted to flex between about 180 degrees, to enable a pair ofadjacent sidewalls 22 to be oriented such that thesidewalls 22 are disposed substantially parallel with their respectiveinner faces 26 directly opposite each other, and about 90 degrees, to enable the pair ofsidewalls 22 to be oriented perpendicularly to each other. It can be readily seen that in a generally square or rectangular embodiment of the ottoman, as shown inFIGS. 1-3B and 7, thesidewall assembly 22 may include two hinges 24 a (adapted to flex between about 0 degrees and about 90 degrees) and two hinges 24 b (adapted to flex between about 90 degrees and about 180 degrees). Alternatively, thesidewall assembly 22 may include fourhinges 24 each adapted to flex between about 0 degrees and about 180 degrees. - When the ottoman 10 is deployed for use, the
side assembly 20 in a first illustrated embodiment is configured into a generally square shape as shown inFIG. 1 , wherein eachsidewall 22 is disposed generally perpendicularly to twoadjacent sidewalls 22 and thehinges 24 are flexed at approximately 90 degrees. As is shown in the exemplary embodiments ofFIGS. 7-10 , an ottoman can be configured in a multitude of other geometric shapes, including but not limited to a rectangle, a pentagon, a hexagon, an octagon, and a multi-sided structure approximating a circle. When thesidewall assembly 20 is in a collapsed state, as depicted inFIG. 3B , thehinges 24 are alternately flexed to approximately 0 degrees and approximately 180 degrees, such that theinner faces 26 of one pair ofsidewalls 22 are disposed directly opposite to theinner faces 26 of another pair ofsidewalls 22, and theentire sidewall assembly 20 is essentially flat and has a thickness approximately equal to that of twosidewalls 22.FIG. 3A shows a partially collapsed transition during assembly or disassembly between the deployed and the collapsed states of thesidewall assembly 20. - The
hinges 24 can be made from any mechanism capable of providing sufficient flexing such as between 0 degrees and 180 degrees. In an embodiment, thehinges 24 are made from a fabric or web of material fastened to theinner face 26 of each of theadjacent sidewalls 22. Afabric hinge 24 has the advantages of full flexibility over its entire range, light weight, and resistance to fatigue failure over long-term use. In addition, fabric hinges 24 permit a small amount of flex in the overall dimensions of the deployedsidewall assembly 20 so as to permit a snug fit of thebottom panel 30 andtop lid 40 when theottoman 10 is assembled. Nevertheless, other hinges 24 may equivalently be used to join thesidewalls 22 together, including piano hinges and/or other mechanical hinges known in the art. - As depicted, particularly in
FIG. 2 , thehinges 24 extend along a middle portion of the junction between a pair ofadjacent sidewalls 22. In another embodiment, thehinges 24 can extend along the entire length of the junction between a pair ofadjacent sidewalls 22. In yet another embodiment, two or more hinges 24 can be used between each pair ofadjacent sidewalls 22, each hinge 24 extending along a portion of the junction between a pair ofadjacent sidewalls 22. Alternatively, a single fabric web can extend around the entire inner periphery of the sidewall assembly for interconnecting all of the sidewalls. - Each of the sidewalls can be solid, as shown for example in
FIGS. 3A-3B and 7-10, or can include an opening of any shape, as shown for example by theopening 54 inFIGS. 1 and 2 . When solid sidewalls are employed, the ottoman can be used for hidden storage, the items within remaining readily accessible by merely removing the top lid. When sidewalls having openings are employed, the bottom panel can be a functional shelf for stowing articles reading material, or other items that could be conveniently accessed in locations where the ottoman is used. A combination of sidewalls, including at least one solid sidewall and at least one sidewall having an opening, can be employed in the same ottoman. - The
bottom panel 30 preferably has a shape that closely matches the shape of thesidewall assembly 20 when deployed, having a number ofedges 36 matching the number ofsidewalls 22 in thesidewall assembly 20. In the illustrated embodiment, when theottoman 10 is deployed for use, thebottom panel 30 is inserted into aninterior space 56 within thesidewall assembly 20, with eachedge 36 in close proximity to theinner face 26 of a correspondingsidewall 22. As shown in detail inFIG. 6 , thebottom panel 30 is supported by a plurality ofsupport members 32. In one embodiment, the support members protrude inwardly from thesidewalls 22 of thesidewall assembly 20. In this embodiment,apertures 34 are disposed in the sidewalls 22 near the bottom ends 50 thereof, theapertures 34 extend at least partially into theinner face 26 of eachsidewall 22. Theapertures 34 may be blinded in thesidewalls 22, or may extend through thesidewalls 22 to theouter face 28. Eachsupport member 32 is inserted partially into anaperture 34 so that a portion of thesupport member 32 is snugly supported by thesidewall 22 and a remaining portion of thesupport member 32 protrudes inwardly from theinner face 26 of thesidewall 22 for supporting thebottom panel 30. Eachsidewall 22 preferably has at least oneaperture 34 adapted for receiving asupport member 32. - In the depicted embodiment, the
support members 32 are pegs having a stepped diameter including anarrower portion 36 for inserting into theaperture 34 and awider portion 38 for protruding inwardly from theinner face 26 of thesidewall 22. It is also contemplated that theapertures 34 can include an internal thread, and thenarrower portion 36 of each peg 32 can include a corresponding external thread for securing thepeg 32 within theaperture 34. Alternatively, thesupport members 32 can be other similar mechanical devices known in the art that can be removably secured to protrude from theinside face 26 of thesidewalls 22 by any reversible means known in the art, including but not limited to a compression fit, nails, screws, shelving supports, or hook and loop fasteners. Still further, thesupport members 32 can be a ledge or flange attached to or formed integrally with thesidewalls 22 and onto which thebottom panel 30 rests. While the illustrated embodiment shows thesupport members 32 attached to thesidewalls 22, it is also contemplated that thesupport members 32 could be outward protrusions formed on thebottom panel 30 that engage with recesses or ledges on theinner surfaces 26 of thesidewalls 22. - The
top lid 40 can have any shape and preferably includes a downwardly extendinglocator 44 that closely matches the shape of thesidewall assembly 20 when deployed, thelocator 44 having a number ofedges 46 matching the number ofsidewalls 22 in thesidewall assembly 20. Thelocator 44 can be a continuous extension formed on thelid 40, such as a downwardly projecting lip, or may be a plurality of flanges extending downwardly from thelid 40 to locate the lid with respect to thesidewall assembly 20. In the illustrated embodiment, thetop lid 40 includes abrim 46 extending outwardly from the periphery of thelocator 44 to rest on the top ends 52 of thesidewalls 22 when theottoman 10 is assembled. When theottoman 10 is deployed for use, thebrim 46 of thetop lid 40 is supported on the top ends 52 of thesidewalls 22 and thelocator 44 is inserted into thesidewall assembly 20, with eachedge 46 in close proximity to theinner face 26 of the correspondingsidewall 22, as shown in detail inFIG. 5 . As depicted, the shape of thetop lid 40 is the same as that of thelocator 44 and the deployedsidewall assembly 20, but thebrim 46 of thetop lid 40 can be of any shape, even a shape that does not correspond to the shape of the deployedsidewall assembly 20. While the illustrated embodiment depicts alocator 44 the conforms to the number ofsidewalls 22, it should be readily apparent that thelocator 44 can be downwardly projecting pins positioned to center thelid 40 on thesidewall assembly 20. In such a configuration, as little as two pins could be used, positioned near opposite bottom edges of thelid 40. It is also contemplated that thelocator 44 may be eliminated and, instead, a second set of support members can extend inwardly from thesidewall assembly 20 near itsupper end 52. In this alternate embodiment, thelid 40 would not include abrim 46, but instead would be sized to fit within thesidewall assembly 20 and be supported by the second set of support members. - To deploy the
ottoman 10 in the illustrated embodiment, beginning with the component parts in a disassembled state, the following steps are taken. Thesidewall assembly 20 is transitioned from its collapsed state, where pairs ofsidewalls 22 lie generally flat on one another, to a generally deployed state, where the foursidewalls 22 are disposed at angles of approximately 90 degrees as interconnected by thehinges 24. Thesidewall assembly 10 is placed on the floor or on another generally horizontal surface with the bottom ends 50 of the sidewalls 22 oriented downward and the top ends 52 oriented upward. Eachsidewall 22 has at least oneaperture 34, eachaperture 34 adapted for removably receiving apeg 32. Thepegs 32 are inserted into theapertures 34, and thebottom panel 30 is inserted into theinterior space 56 within thesidewall assembly 20 at the opentop end 52 thereof, until thebottom panel 30 is supported by the plurality ofpegs 32. The close fit between theedges 36 of thebottom panel 30 and the inner faces 26 of thesidewalls 22 provides stability to the structure and shape of theottoman 10. Finally, thetop lid 40 is positioned on thetop end 52 of thesidewall assembly 20 so that thelocator 44 sits inside thesidewall assembly 20 surrounded by the inner faces 26 of thesidewalls 22 and thebrim 46 rests on the top ends 52 of thesidewalls 22. To return theottoman 10 to a collapsed state, the preceding steps can simply be done in reverse order. - Although the
ottoman 10 described above comprises asidewall assembly 20 having foursidewalls 22 of approximately equal dimensions, other embodiments of an ottoman are envisioned. As depicted inFIG. 7 , anottoman 110 has a generally rectangular shape and comprises asidewall assembly 120, a bottom panel (not shown), and atop lid 140. Thesidewall assembly 120 has a pair ofopposed sidewalls 122 and a pair ofopposed sidewalls 123 having a width that is less than the width of thesidewalls 122. Eachsidewall 122 is interconnected by a hinge 124 to anadjacent sidewall 123 at either end thereof, and similarly, eachsidewall 123 is interconnected by ahinge 123 to anadjacent sidewall 122 at either end thereof. The manner of supporting the bottom panel and thetop lid 140 in theottoman 110 is the same as described above with regard to theottoman 10. - In general, an ottoman having any number of sides can be made that is readily assembled for use and is readily collapsed into generally flat component parts. As depicted in
FIG. 8 , anottoman 210 has a generally hexagonal shape and comprises a generallyhexagonal sidewall assembly 220 having sixsidewalls 222 interconnected by hinges 224, a bottom panel (not shown), and atop lid 240. As depicted inFIG. 9 , anottoman 310 has a generally octagonal shape and comprises a generallyoctagonal sidewall assembly 320 having eightsidewalls 322 interconnected by hinges 326, a bottom panel (not shown), and atop lid 340. - In addition, an ottoman having a large number of sides can be made to resemble a circular shape while still being readily assembled and collapsible into easily transportable and stowable component parts. As depicted in
FIG. 10 , anottoman 410 has a generally circular shape and comprises asidewall assembly 420 having a large number ofsidewalls 422, a generally circular bottom panel (not shown), and a generally circulartop lid 440. Thesidewall assembly 420 further comprises a fabric hinge 424 interconnecting each adjacent pair ofsidewalls 422. Alternatively, a single fabric web can extend around the entire inner periphery of thesidewall assembly 420 for interconnecting all of thesidewalls 422 into a ring. In a collapsed state, when thetop lid 440 and bottom panel have been removed, thesidewall assembly 420 can be folded flat, or can be rolled up due to the flexibility of the hinges 424 interconnecting thesidewalls 422. - Although the depicted embodiments each have all the sidewalls attached with a hinge, it is contemplated that one set of adjacent sidewalls may have a removable attachment, such as hook and loop fasteners. In this embodiment, the sidewalls would be arranged into to desired shape and the final sidewalls interconnected.
- While the invention has been disclosed with reference to certain preferred embodiments, numerous modifications, alterations, and changes to the described embodiments are possible without departing from the sphere and scope of the invention, as defined in the appended claims and equivalents thereof. Accordingly, it is intended that the invention not be limited to the described embodiments, but that it have the full scope defined by the language of the following claims.
