DETAILED DESCRIPTION
The following description is not to be taken in a limiting sense, but is made for the purpose of describing the general principles of the present disclosure. The scope of the present disclosure should be determined with reference to any claims filed in the future, and with the understanding that other changes and modifications to the invention can be made.
The disclosed subject matter is a modular furniture system 100, see FIGS. 1 and 2, and, as shown in one embodiment, is comprised of basic components that may be multiplied, configured, and reconfigured to create different types of furniture, including but not limited to beds, tables, seating, shelving, and even simple structural shelters—all without requiring the use of tools. In an exemplary embodiment, the furniture system 100 comprises triangular frames 102, a leg support system 104, soft or hard surfaces (e.g., cushions 106 or table surfaces 118), frame hinges 108, and o-rails 116, as well as other hardware useful to interlock the furniture components together. A basic module of the furniture system 100 is a triangular frame 102 which can be used singularly, such as for a table or shelf 112, or in combination, such that multiple triangular frames are hinged together for seating (e.g., hexagonal seating) or larger tables or shelving.
The disclosed furniture system 100 is a modular construction such that pieces of furniture can be made as small or large, or as simple or complex as needed by assembling selected components in various configurations. The disassembled components can be light-weight, easily packaged and transported. Also, the flexibility of the modular design of the present furniture system gives it a universal appeal for residential use, e.g., homes, apartments, and dorm rooms, as well as for commercial use, e.g., hotels, schools, businesses, and public areas.
Further, the disclosed furniture system 100 is a solution to a chronic and pervasive problem: supplying large populations with basic human comforts in the wake of environmental or economic devastation. It is designed for easy assembly to provide furniture in disaster housing, a forest hut, or even the interior of a cave. It can be adapted to give comfort to people of different global cultures and styles. Disassembled, the components of the furniture system 100 can be carried easily through narrow spaces, elevators, or stairwells, hence solving a surprisingly common problem—that furniture and furniture components may be too large to transport to certain rooms and locations.
In embodiments, the furniture system 100 easily hinges together and due to its triangular design, distributes considerable weight, where each of the basic triangular frames 102, is supported by three leg support systems 104 to provide a stable platform. Further, the furniture system 100 can grow and evolve (with its users as demand grows) through the addition of components. There are dozens of additional modules which seamlessly add-on to the base components.
The frame components of the furniture system 100, such as the leg supports or portions of the triangular frames 102, can be made out of a variety of materials, including wood or metal. In an embodiment, such components are molded out of lightweight, inexpensive, renewable, and recyclable materials such as plastic or composite material. The use of lightweight, durable materials, combined with economical packaging could save enormous energy and resources during storage and transport.
In embodiments, the furniture system 100 is designed to use readily available materials. For example, the sizes of all hard and soft surface materials (cushion foam, plywood, recycled plastics, and composite resins) are generally available in 24-48′′ widths. Accordingly, in an embodiment, the interior of the standard triangular frame 102 may be scaled to conform to such standard sizes to conserve materials and reduce waste. The triangular frame 102 also may have either a hard surface (e.g., for a table or shelf 112) or a soft surface (e.g., cushion 106 used for seating). In another embodiment, an inflatable cushion can be used with a triangular frame 102 of the furniture system 100, providing multi-functionality with even fewer components and easier transport and storage.
The furniture system 100 may be produced as a high-end product or a low-end product, as well as an indoor or outdoor product. The target use of a particular furniture design dictates what types of materials are used. For example, a high-end, indoor furniture design may use chrome and leather, whereas a low-end, outdoor furniture design may use plastic and all-weather cushions. Further, the furniture system 100 allows for many different aesthetically pleasing and functional designs, which can conform to both residential and commercial settings. Cushions 106, shelves 112, and leg support systems 104 can be produced in a variety of colors, finishes and patterns.
The figures illustrate exemplary components of the furniture system 100 and certain possible designs and configurations that may be created using the furniture system 100. It should be understood that the illustrated furniture designs are for convenience only and should not be construed as the only possible designs that may be created using the components of the furniture system 100. For example, the height of the leg support system 104 can be increased by stacking multiple vertical supports 204. Leg support systems 104 that are only one vertical support 204 in height may be used for a coffee table. If a cushion 106 or soft surface is added the furniture can be a sofa or bed to which an upper support cushion 114 or a headboard could optionally be added. The upper support cushions 114 may be used to provide back support or optionally placed on the side of the configuration and used as a side cushion or arm rest. Leg support systems 104 that stack additional vertical supports 204 can increase the height of furniture to standard tabletop height. In another embodiment, stacking yet another vertical support 204 results in a leg support system 104 for bar height furniture. In other embodiments, the stacking of vertical supports 204 and triangular frames 102 creates modular shelving units as shown in FIG. 8.
FIG. 2 is an exploded view showing certain components of a chair 218 and table 220 of the furniture system 100. A principal component of the furniture system 100 is a triangular frame 102 having three frame rails 222, three vertices 224, and a frame surface being either a soft surface, e.g., a cushion 106, or a hard surface, e.g., a board 216. A hinge system including a plurality of frame hinges 108 interconnects the frame rails 222. A second principal component of the furniture system 100 is a leg support system 104 for supporting the furniture, such as the chair 218 and table 220 of FIG. 2. The leg support system 104 can include a plurality of vertical supports 204, bottom caps 202, spacer rings 206, spacer bars 210, and top caps 214, all of which can be slidably and removably interconnected, and which support the triangular frame 204 at its vertices 224. In an embodiment, a leg support system 104 is assembled to support a vertex 224 of a triangular frame 102, by inserting a bottom cap 202 into a bottom end of a vertical support 204. One or more spacer rings 206 can be inserted on the top end of the vertical support 204. A frame hinge 108 can be removably slid onto the top end of the vertical support 204, after which another spacer ring 206 may be slid onto the vertical support 204 as well as a top cap 214. Once the triangular frame 102 is assembled with its leg support system 104, the design can easily become a chair 218 by adding a cushion 106 to the triangular frame 102 or a table 220 by adding a board 216 to the triangular frame 102.
As also shown in FIG. 2, an upper support cushion 114 can be attached to the chair 218 to provide back support by adding a second level of vertical supports 204 to the top of spacer bars 210 (which were placed onto the top of the first level of vertical support 204). As depicted in the embodiment illustrated in FIG. 2, vertical supports 204 are stacked on top of two of the vertices 224 of the triangular frame 102 in place of top caps 214. This creates the second level of vertical supports 204. An o-rail 116 can be connected to the top of each vertical support 204 in the second level of vertical supports 204 to provide support to the upper support cushion 114. In another embodiment, the upper support cushion 114 is attached to the o-rail. For example, the upper support cushion 114 can be attached by simple loops in the fabric, Velcro or any other suitable means. The o-rail 116 is slidably removable onto the second level of vertical support 204, after which additional spacer rings 206 and top caps 214 can be added. A partial cutaway of a cross-sectional side view of the embodiment of an assembled chair 218 is shown in FIG. 3. Thus, because the frame hinges 108 of the furniture system 100 are uniform and hidden, they can be used in such a way that allows for endless customization of furniture designs.
FIGS. 4-9 illustrates various examples of furniture designs using the furniture system 100 of the present invention. The triangular frames 102, leg support system 104, frame hinges 108, and other components of the furniture system 100 are used in different configurations to achieve the desired piece of furniture. Also, because of the modular, easy-to-use component design, these pieces of furniture can be easily disassembled and reconfigured into a new design. FIG. 4 shows an exemplary hexagonal seating design 400; FIG. 5 shows an exemplary design 500 having a C-shaped seating design 502 with two end tables 504a, 504b and a center seating area 506. FIG. 6 shows an exemplary design 600 having a center table 602 with two bench seating arrangements 604a and 604b. FIG. 7 shows an exemplary design 700 having a large seating area 702 with upper support cushions and an attached table 704. FIG. 8 shows an exemplary stacked shelving design 800 having three tiers or levels of shelving 802a, 802b, and 802c, each level created using a set of triangular frames 102. FIG. 9 shows a second exemplary stacking shelving design 900 having four tiers or levels of shelving 902a, 902b, 902c, and 902d. 
FIG. 10 shows a disassembled triangular frame 102 having three frame rails 222 and three frame hinges 108. Each frame rail 222 has an exterior side 1112 and an interior side 1114, with a receiving mechanism within said interior side 1114. Each frame hinge 108 has a ring portion 1002 and a connecting mechanism for interconnecting the frame hinge 108 to the receiving mechanism of a frame rail 222. In one embodiment, the connecting mechanism is a flange portion 1004 and the receiving mechanism is an interior channel 1110 such that the flange portion 1004 of a frame hinge 108 slides into and is disposed within the interior channel 1110 of a frame rail 222, thereby interconnecting the frame rail 222 with the frame hinge 108. Also, in certain embodiments a hinge pin 1008 is used to further secure a frame rail 222 to the flange portion 1004 of a frame hinge 108. The flange portion 1004 may have two holes 1006a and 1006b such that a first hinge pin 1008 passes through a first hole 1006a in the flange portion 1004 and a hole in the interior side 1114 of a first frame rail 222, and a second hinge pin 1008 passes through a second hole 1006b in the flange portion 1004 and a hole in the interior side 1114 of a second frame rail 222. The use of hinge pins 1008 to secure a frame rail 222 to a flange portion 1004 of a frame hinge 108 is for convenience. It is understood to those of ordinary skill in the art that other means for securing two component parts of a frame work equally as well. Accordingly, FIG. 11 shows an exemplary design whereby three triangular frames 102 are joined together using the frame hinges 108 and hinge pins 1008 as described above.
FIG. 12 shows an exemplary embodiment of a frame rail 222 wherein the external side 1112 of the frame rail 222 has three channels 1202a, 1202b, and 1202c. These channels 1202a, 1202b, 1202c are useful to removably attach a decorative panel to the exterior side 1112 of the frame rail 222. Additionally, FIG. 12 shows an exemplary frame rail 222 wherein the internal side 1114 of the frame rail 222 has an interior channel 1204. Interior channel 1204 is useful to secure cushion 106, table surface 118, or other similar surfaces to the frame rails 222 that comprise the triangular frames 102. In one embodiment, interior side 1114 may have two holes 1206a and 1206b to further secure a frame rail 222 to the flange portions 1004 of a first frame hinge 108 and second frame hinge 108. The flange portion 1004 of the first frame hinge 108 may have a first hole 1006a such that a first hinge pin 1008 passes through a first hole 1006a in the flange portion 1004 and a hole 1206a in the interior side 1114 of a frame rail 222, and a second hinge pin 1008 passes through a second hole 1006b in the flange portion 1004 of the second frame hinge 108 and a hole 1026b in the interior side 1114 of the frame rail 222. As discussed above, the use of hinge pins 1008 to secure a frame rail 222 to a flange portion 1004 of a frame hinge 108 is for convenience. It is understood to those of ordinary skill in the art that other means for securing two component parts of a frame work equally as well.
In the embodiment illustrated in FIG. 12, the ends of the internal side 1114 of the frame rail 222 are tapered. In embodiments, each end of the of the internal side 1114 is cut or formed at a diagonal from the end of the frame rail 222, such that if two frame rails 222 meet at a vertex, they form a mitered joint, as can be seen in FIG. 10. In another embodiment, not shown, the ends of the internal side 1114 of the frame rail 222 may be notched, set back or removed from the ends of the frame rail 222 to facilitate manufacture and potentially to reduce material costs.
FIG. 13 shows three exemplary frame hinges 108. In certain embodiments the position of the flange portion 1004 varies relative to the ring portion 1002. For example, in an embodiment, the furniture system 100 includes three or more types of frame hinges 108 based upon the position of the flange portion 1004 relative to the ring portion 1002: a high flange frame hinge 1304, a mid-flange frame hinge 1302 and a lower flange frame hinge 1306. In the high flange frame hinge 1304, the flange portion 1004 is approximately aligned with the center of the ring portion 1002. In the mid-flange frame hinge 1302, the top surface of flange portion 1004 is approximately aligned with the lower edge of the ring portion 1002, and in the lower flange frame hinge 1306, the flange portion 1004 is located below the ring portion 1002. The high flange frame hinge 1304, mid-flange frame hinge 1302 and lower flange frame hinge 1306 are exemplary configurations and the flange portion 1004 can be positioned at numerous locations relative to the ring portion 1002.
As previously described, frame hinge 108 may have its flange portion 1004 located at various positions relative to the ring portion 1002. In an embodiment, the various flange portion positions allow the connection of frame hinges 108, to the same vertical support 204 while maintaining a level surface between connected triangular frames 102. In an embodiment, the various flange portion positions allow users to maintain a level surface between connecting triangular frames 102 when a corresponding vertical support 104 is also needed to connect a diagonal support rail 120, as depicted in FIG. 11n an embodiment, spacer rings 206 are used in combination with frame hinges 108 to achieve the desired level surface. Additionally, in an embodiment, spacer rings 206 may be used with spacer bars 210 and o-rails 116 to achieve the desired elevation to support an upper support cushion 114.
FIG. 13A depicts an alternative embodiment of a frame hinge 108a, formed from individual pieces. As depicted, this embodiment of the frame hinge 108a can be assembled from a ring portion 1002a, a hinge base 1308a, and one or more flange portions 1004a. Here, the ring portion 1002a, hinge base 1308a and flange portions 1004a are each machined separate and assembled to form a completed frame hinge. Separate machining and assembly may reduce manufacture costs. In other embodiments, the ring portion 1002a may be produced as a separate component, while the hinge base 1302a and flange portions 1004a are formed as a single component. Alternatively, the flange portions 1004a may be formed as separate components and the ring portion 1002a and hinge base 1308a may be formed as a single component.
When assembled, the ring portion 1002a can be formed with a tab 1310a that can be fitted into a ring channel 1312a of the hinge base 1308a. The ring portion 1002a can be secured to the hinge base 1308a using a bolt, cotter pin or any other suitable mechanism. The flange portion 1004a is fitted between hinge base projections 1314a. The flange portion or portions 1004a can be secured to the hinge base 1308a using a bolt, cotter pin or any other suitable mechanism. FIG. 13A depicts a frame hinge 108a with a flange portion 1004a and a ring portion 1002a associated with a single hinge base 1308a. However, in other embodiments, the ring portion 1002a can include one or more additional tabs 1310a, such that the ring portion 1002a can be assembled with two or more hinge bases 1308a. Each hinge base 1308a, can support a separate flange portion 1004a, such that the frame hinge 108a is capable of connecting multiple triangular frames 102 with a single ring portion 1002a.

The triple flange frame hinge 1702 is capable of supporting three triangular frames 102, allowing three triangular frames 102 to be connected using a single frame hinge of this type, rather than requiring a separate single flange frame hinge 108 to connect each of the triangular frames 102 at the vertex 224. Two triple flange frame hinges 1702 can be combined to support six triangular frames 102 in a triangular configuration as shown in FIG. 4. In certain embodiments, a triple flange frame hinge 1702 may be used to connect frame rails 222. The triple flange frame hinge 1702 is comprised of a ring portion 1002 and a triple flange portion 1704 having a first flange portion 1706, a second flange portion 1708, and a third flange portion 1710. In an embodiment, the first flange portion 1706, the second flange portion 1708, and the third flange portion 1710 each may function separately as a flange portion 1004 when connecting frame rails 222 as depicted in FIGS. 10-12.
FIG. 18 shows an exemplary triple flange twin ring frame hinge 1802 from various angles. Similar to the embodiment of the triple flange frame hinge 1702 shown in FIG. 17, the triple flange twin ring frame hinge 1602 allows a single frame hinge of this type to connect three triangular frames 102. In certain embodiments a triple flange twin ring frame hinge 1802 may be used to connect frame rails 222. The triple flange twin ring frame hinge 1802 is comprised of a triple flange portion 1704 having a first flange portion 1706, a second flange portion 1708, and a third flange portion 1710, and a twin ring portion 1404 having an upper ring portion 1406 and a lower ring portion 1408.
The vertical positioning of the flange portions relative to each other and to the ring portions as depicted in FIGS. 13-18 are examples. It is understood to those of ordinary skill in the art that the flange portions and the ring portions may be located in any number of vertical positions relative to each other, including having a means to adjust the vertical position of the flange portions relative to each other and to the ring portions. Furthermore, the distribution of the flange portions relative to each other depicted in FIGS. 15-18 are examples. It is understood to those of ordinary skill in the art that the flange portions may be distributed about the ring portions in any number of degrees relative to each other, including but not limited to adjacent and touching to each other to equally distributed around the ring portions.
FIG. 19 shows a disassembled exemplary o-rail 116. In an embodiment, each o-rail 116 is comprised of an o-rail member 1902 having a first end 1910 and a second end 1912, with a receiving mechanism within said first end 1910 and said second end 1912, and two o-rail frame hinges 1904. Each o-rail hinge 1904 has a ring portion 1002 and a connecting mechanism for interconnecting the o-rail hinge 1904 to the receiving mechanism of an o-rail member 1902.
