DETAILED DESCRIPTION

(23) Turning now to the drawings, wherein like numbers denote like parts throughout the several views, embodiments consistent with the invention utilize one or more tensioning mechanisms to draw interlocking framing members of knock-down furniture, including transversely-oriented interlocking framing members, together between opposed anchor points using directed linear tension between the anchor points and applied by a tensioning device.

(24) FIG. 1, for example, illustrates an example embodiment of a tensioning mechanism 2 including a pair of opposed anchor points 10a, 10b separated along a linear axis 4 and a tensioning device 12 suitable for use in securing interlocking framing members together under tension. In this embodiment, anchor points 10a and 10b are configured to be integrally formed on a framing member, or otherwise mounted to a framing member in a semi-permanent or permanent manner, e.g., through the use of adhesives, screws, nails, rivets and/or other known fasteners or fastening mechanisms. Further, anchor points 10a and 10b in this embodiment are formed or mounted during manufacture, and thus already formed or mounted to a framing member prior to sale to a consumer, such that the consumer is not required to mount the anchor points to the framing members.

(25) For example, as illustrated in FIG. 2, anchor points 10a and 10b are illustrated as respectively mounted to a pair of framing members 14, 16. Framing members 14, 16 are both transversely-oriented relative to one another and interlocking. Framing member 14, for example, is a lateral-type framing member, e.g., a table top, shelf, desk top, seat top, stool top, mantle, ledge, rack, or other type of framing member that is generally horizontally-oriented after assembly, while framing member 16 is a vertical-type framing member such as a table leg, a chair leg, a support, a structural side, a structural wall, a riser, a pillar, a joist, or other type of framing member that is generally vertically-oriented after assembly. As such, at least portions of framing members 14, 16 extend in directions that are generally transverse or orthogonal to one another. In other embodiments, e.g., as illustrated by the bed frame embodiment discussed below, framing members can be transversely-oriented relative to one another without necessarily being horizontally or vertically-oriented after assembly, so the invention is not limited to the enumerated types of framing members discussed above, and may be used to secure together a multitude of different types of framing members.

(26) In addition, in some embodiments the framing members may be transversely-oriented without being specifically at a 90 degree orientation relative to one another. For example, two framing members that extended in directions that are 45 or 60 degrees relative to one another may, in some embodiments, be considered to be transversely-oriented relative to one another. Furthermore, it will be appreciated that in some embodiments more than two framing members may be secured together using a single tensioning mechanism, and as such, some framing members secured together by a tensioning mechanism may be parallel or coaxial relative to other framing members to which they are secured by a tensioning mechanism, e.g., as illustrated by the shelf embodiment discussed below.

(27) As noted above, at least a portion of the framing members secured together by a tensioning mechanism are also interlocking in nature, such that when the framing members are assembled together and secured by a tensioning mechanism, the framing members are generally restricted from movement relative to one another to provide a sturdy furniture component. The interlocking of framing members may generally be dictated by the structural design of each framing member, and may incorporate cooperating slots, tabs, apertures, sleeves, pins, dowels, keys and other types of cooperative joint structures, and in many cases based upon cooperative male and female members, each of which may be referred to herein as a feature. Features may incorporate various structures for keying framing members together, e.g., utilizing keying configurations such as slotting, joinery, pinning, notching, etc. In many embodiments, the interlocking nature of the framing elements is used to restrict movement in one or more directions other than a direction along which tension is applied by a tensioning mechanism.

(28) Collectively, the framing members that are secured together under tension by a tensioning mechanism may be considered to form an interlocking relationship when at least two of the framing members interlock with one another either directly (e.g., in the example shelf discussed below), or in some embodiments through an intermediate member, e.g., an anchor point (e.g., in the example table discussed below).

(29) As shown in FIG. 2, for example, a slot 17 in framing member 16 may be sized and configured to receive anchor point 10a, which is in turn integrally formed on framing member 14, such that when anchor point 10a is received in slot 17 (as illustrated in FIG. 3), movement of framing member 14 relative to framing member 16 is restricted, thereby interlocking framing members 14 and 16. Other structures suitable for providing an interlocking relationship between framing members are illustrated in the other embodiments discussed hereinafter and/or will be appreciated by one of ordinary skill in the art having the benefit of the instant disclosure.

(30) Framing members 14, 16 may be formed of a number of different materials used for furniture and other structures. In one embodiment, for example, the framing members may be constructed by laser cutting a detailed pattern from plywood, medium density fiberboard (“MDF”), or other manufactured lumber. Additionally, framing members may be manufactured by traditional carpentry methods, fabricated from stamped and/or bent sheet metal, molded from plastic material, etc. In some embodiments, anchor points 10a, 10b may also be integrally formed in a similar manner. Otherwise, anchor points 10a, 10b may be formed separately and mounted to the framing members through the use of adhesives and/or various fasteners, as discussed above.

(31) Returning to FIG. 1, tensioning mechanism 2 also includes a tensioning device 12, which generally includes at least one tensioning member configured to apply tension along a linear axis (e.g., linear axis 4) and between opposing anchor points, and a securing mechanism coupled to the at least one tensioning member and configured to control the tension applied through the at least one tensioning member, in some embodiments by controlling an effective length of the at least one tensioning member extending between the opposing anchor points. In the embodiment of FIG. 1, the securing mechanism is implemented as a ratchet 13a and the tensioning member is implemented as a strap or band 13b, with the ratchet 13a configured to adjust an effective length of strap 13b such that when strap 13b encircles anchor points 10a, 10b, the anchor points are drawn together under tension applied along the length of the strap. As such, anchor points 10a, 10b desirably are configured to receive strap 13b. While in some embodiments, anchor points 10a, 10b need not include any structure that restricts the movement of strap 13b when no tension is applied, in the illustrated embodiment of FIG. 1, anchor points 10a, 10b are specifically configured to retain strap 13b. Anchor point 10a, for example, is formed with three stacked cuboid portions 11a, 11b and 11c, with the dominant faces of the outer cuboid portions 11a, 11b being larger than that of the inner cuboid portion 11c such that a channel 15a is defined between the inner cuboid portion 11c and the underside of framing member 14 (see FIG. 2). As such, as illustrated in FIG. 3, strap 13b may be inserted in through channel 15a formed between inner cuboid portion 11c and the underside of framing member 14. Anchor point 10b may also be formed in a similar manner, and as shown in FIG. 2, channels 15b are defined between anchor point 10b and an inner wall of framing member 16, and further, channel 15a formed by anchor point 10a and the underside of framing member 14 extends around and between inner cuboid portion 11c of anchor point 10a and the inner wall of framing member 16 when framing members 14, 16 are interlocked together.

(32) Tensioning mechanism 2 is configured as a looped tensioning mechanism, as strap 13b forms a loop around anchor points 10a and 10b. In other embodiments, e.g., as illustrated in FIG. 8 below, a point-to-point tensioning mechanism may be used instead, whereby instead of forming a loop, a point-to-point coupling is made between the opposing anchor points, optionally with hooks, rings, karabiners, or other structures suitable for engaging with the anchor points to apply tension to the anchor points and thereby draw the anchor points together, in some embodiments generally along a single, linear axis or direction.

(33) Strap 13b is generally formed with a flexible and durable construction, may be woven to improve strength, and may be formed of various elastic or inelastic materials, including various plastics, rubber, metal, natural fibers, or synthetic fibers. In addition, rather than using a strap, a tensioning device 12 consistent with the invention may use another type of tensioning member, e.g., a cord, band, rope, belt, cable, wire, chain, rod or other construction (as well as combinations thereof) that permits tension to be applied to draw opposing anchor points together and apply tension along the length thereof.

(34) In addition, while tensioning mechanism 2 is illustrated with a tensioning device incorporating a securing mechanism implemented as a ratchet 13a, it will be appreciated that a tensioning mechanism consistent with the invention may utilize other types of tensioning devices, including hand winches, come-a-longs, turnbuckles, pressure clamps, tension rods, or other devices capable of applying tension along a direction extending between opposing anchor points to thereby draw the anchor points, and their associated and interlocked framing members, together under tension. Other securing mechanisms, e.g., other ratchets, winches, etc., may be used to apply tension to the band. The securing mechanisms are desirably, but not necessarily, capable of being released to enable easy disassembly and reassembly. Moreover, while the illustrated embodiments apply tension via a ratchet that engages both ends of the strap, in other embodiments, one or both ends of the strap may be secured, for example, to the anchor points themselves, e.g., via hooks. In yet other embodiments, a strap may be formed from multiple straps that are joined together in a tensioned relationship by a ratchet or other securing mechanism.

(35) Thus, with reference to FIGS. 2 and 3, to assemble framing members 14, 16 together, strap 13b of tensioning mechanism 2 may be inserted through channels 15a, 15b, and framing member 14 may be interlocked with framing member 16, e.g., with anchor point 10a received in slot 17 of framing member 16. Ratchet 13a may then be actuated to decrease the effective length of strap 13b, and once any slack in the strap 13b is taken up, further actuation of ratchet 13a applies increasing tension through strap 13b and along linear axis 4 to draw the anchor points together, effectively drawing or compressing framing members 14 and 16 together under tension in an interlocking relationship. Disassembly may then be achieved by releasing ratchet 13a to remove tension from strap 13b, enabling the framing members to be separated and the tensioning device to be removed.

(36) The herein-described functionality may be used in connection with a number of different types of furniture components consistent with the invention. A furniture component, in this regard, may be considered to be a piece or item of furniture, or in the least a structural component of a piece or item of furniture.

(37) As noted above, one residential application of this configuration of furniture component is to provide home furnishings, including knock-down furniture such as tables, chairs, stools, shelving units, desks, cabinets, beds, sofas, loveseats, storage units, dressers, and other types of un-upholstered or upholstered furniture, etc., that can be assembled and disassembled, in many instances without the use of hardware or special tools, as the tension applied by the tensioning mechanism coupled with the interlocking nature of the framing members secures the framing members together. When it is time to move, the tension may be removed, the framing members may be separated, and the furniture component can be moved in pieces rather than as a whole. This may allow in some embodiments for one individual to move an item that would traditionally require multiple people to be moved. Additionally, it allows in some embodiments for larger furniture components that would traditionally need to be moved in large vehicle, such as a truck or van, to be moved in a compact car. Another similar application is in corporate or other office environments, where it may be desirable to move furniture between offices and/or locations.

(38) Another commercial application of this configuration is a tradeshow application, wherein tradeshow furniture, e.g., displays, tables, and the like are moved into a particular location such as convention center, used only for a few days, and then moved to another location. In many tradeshow applications, an ability to disassemble and reassemble tradeshow furniture reduces drayage costs and allows disassembled furniture components to be crated with maximum efficiency and reduced drayage trips. In addition, the use of tensioning mechanisms for assembly rather than hardware and tools may also bypass the need for using unionized labor, thereby reducing additional costs associated with exhibiting at tradeshows.

(39) Now turning to FIG. 4, this figure illustrates an example table constructed and assembled in accordance with the techniques described above. In particular, a tabletop 18, configured as a lateral-type framing member, is shown secured to four table legs 16a-16d, configured as vertical-type framing members similar to framing member 16 of FIGS. 2-3. Tensioning devices 12a-12d, configured similar to tensioning device 12 of FIG. 1, utilize anchor points similar to anchor points 10a, 10b of FIG. 1 to form tensioning mechanisms that draw together tabletop 18 and table legs 16a-16d under tension into interlocking relationships. It should be noted that in this configuration each tensioning device 12a-12d is primarily encased within the respective framing members 16a-16d, and thus, as illustrated in FIG. 5, the tensioning devices are generally hidden from view in the assembled table.

(40) FIG. 6 next illustrates another type of anchor point, position (P) anchor 20, which may be used in some embodiments consistent with the invention. P anchor 20, in one embodiment, is not integrated into a framing member, but it is instead configured to interlock with a framing member at a pre-determined, structurally-beneficial position on the framing member. A P anchor may be molded or fabricated from a dense and/or durable material such as a metal or plastic material, and may be, for example, formed of a structurally stronger material than the framing member to which it is interlocked. In some embodiments, a P anchor may be received in a corresponding aperture in a framing element and further may be removable therefrom after disassembly.

(41) P anchor 20 includes a cleat point 24, e.g., incorporating a cylindrical bar extending between a pair of opposing supports. In addition, P anchor 20 includes a plate 21 that, as may be seen, for example, in FIG. 9, is sized and configured to interlock P anchor 20 with a framing member (e.g., framing member 26 of FIG. 9) such that tension applied to the cleat point 24 is likewise communicated to the associated framing member. In addition, as shown in FIG. 7, when used in a tensioning mechanism incorporating a looped tensioning device such as tensioning device 12, cleat point 24 serves to re-direct the force of the tensioning device 12 by turning cycled linear tension into compression between opposing P anchors 20a, 20b, generally along linear axis 4a, thereby drawing the P anchors 20a, 20b toward one another.

(42) P anchor 20 may also be used in connection with a point-to-point tensioning device. As shown in FIG. 8, for example, P anchors 20a, 20b may be secured to one another using a point-to-point tensioning device 22 including opposing hooks 23a that engage with cleat points 24 of P anchors 20a, 20b, and that are mounted at opposing ends of a cord 23b (which may be multi-part) coupled to a ratchet 23c, thereby applying tension or compression between P anchors 20a, 20b along linear axis 4a.

(43) FIGS. 9-21 next illustrate a number of different furniture components or items that may utilize the tensioning mechanisms described herein. For example, FIGS. 9-11 illustrate the construction and assembly of an example stool utilizing the P anchors of FIGS. 6-8. As shown, a pair of lateral-type framing members 26, 30, respectively representing the seat and base of the stool, are secured to opposing ends of a vertical-type framing member 28 by a tensioning mechanism including a tensioning device 12 and P anchors 20a, 20b.

(44) To assemble the sample stool, P anchor 20b may be interlocked with lateral-type framing member 30 through a slot 31, and may be sized and configured to project beyond the upper surface of framing member 30. As such, framing member 28 may be placed over P anchor 20b such that P anchor 20b projects into a slot 33 in framing member 28. Next, P anchor 20a may be interlocked with lateral-type framing member 26 through a slot 27, and may be sized and configured to project beyond the underside of framing member 26. As such, P anchor 20a may inserted into slot 29 of framing member 28 to set lateral-type framing member 26 on top of the entire assembly.

(45) Also, in this embodiment, framing member 28 includes an opening 32 through which tensioning device 12 may be inserted to loop the strap thereof around the cleat point of each P anchor 20a, 20b, and the ratchet of the tensioning device may be actuated to apply tension to the strap and thereby compression lock framing members 26, 28, and 30 together under tension in an interlocking relationship. As illustrated in FIG. 11, when the stool is assembled, tensioning device 12 is primarily encased in framing member 28, but may still be visible through opening 32. In other embodiments, however, a framing member similar to framing member 16 of FIGS. 2-3 may be used, whereby tensioning device 12 may be hidden from view.

(46) FIGS. 12-14 next illustrate an example shelf or bookcase that may utilize the P anchors of FIGS. 6-8. As shown in FIG. 12, the shelf may include four vertical-type framing members 36a, 36c, 40a, 40c, three lateral-type framing members 34, 38, and 42 (with framing members 34 and 38 serving as shelves and framing member 42 serving as a base), and two tensioning mechanisms, a first including two P anchors 20a and 20b and a tensioning device 22a to apply tension along a linear axis 4b, and a second including two P anchors 20c and 20d and a tensioning device 22c to apply tension along a linear axis 4c. Tensioning devices 22a and 22c are similar to tensioning device 22 of FIG. 8, although in other embodiments, a tensioning device similar to tensioning device 12 may be used.

(47) To assemble the example shelf, P anchors 20b and 20d may be interlocked to features 42a and 42c of lateral-type framing element 42, and vertical-type framing elements 40a and 40c may be placed on features 42a and 42c such that P anchors 20b and 20d and features 42a and 42c are received in cooperative slots 41a and 41c of framing elements 40a and 40c. Lateral-type framing element 38 may then be placed on top of framing elements 40a and 40c such that features 39a and 39c thereof project through slots 38a and 38c in framing member 38. Features 39a and 39c may be sized and configured to project beyond the upper surface of framing member 38 such that vertical-type framing members 36a and 36c may be placed on top of framing member 38 with slots 37a and 37c thereof receiving features 39a and 39c of framing members 40a and 40c.

(48) P anchors 20a and 20c may then be interlocked with slots 34a and 34c in lateral-type framing member 34, and framing member 34 may be placed on framing members 36a and 36c such that P anchors 20a and 20c interlock with slots 35a and 35c of framing members 36a and 36c.

(49) Framing members 40a and 40c respectively include openings 40b and 40d through which tensioning devices 22a and 22c may be inserted to respectively engage their hooks with P anchors 20a/20b and 20c/20d, and the ratchets of the tensioning devices 22a and 22c may be actuated to apply tension to the cords and thereby compression lock framing members 36a, 36c, 40a, 40c, 34, 38, and 42 together under tension in an interlocking relationship. As illustrated in FIG. 14, when the shelf is assembled, tensioning devices 22a and 22c are primarily encased in vertical-type framing members 36a, 36c, 40a and 40c, but may still be visible through openings 40b and 40d of framing members 40a and 40c. In other embodiments, however, a framing member similar to framing member 16 of FIGS. 2-3 may be used, whereby tensioning devices 22a and 22c may be hidden from view. In addition, it will be appreciated that framing members not in direct contact, but nonetheless in a linear or coaxial orientation with tensioning devices 22a and 22c are all pressure locked together under a common channel of compressing force.

(50) The shelf illustrated in FIGS. 12-14 also illustrates a number of different interlocking arrangements between framing elements. In some embodiments, for example, a furniture component may include at least one planar framing member, e.g., a table top, shelf, desk top, seat top, stool top, mantle, ledge, or rack and at least one elongated and at least partially hollow framing member, e.g., a table leg, a chair leg, a support, a structural side, a structural wall, a riser, a pillar, a joist that interlocks with the planar framing member proximate one end thereof and in a generally transverse orientation, e.g., with an axis of the elongated framing member being generally normal to a surface of the planar framing member, and that includes an interior channel disposed at least partially between the opposing ends of the elongated framing member through which at least a portion of a tensioning device may extend. The interlocking may be implemented, for example, via an aperture in the planar member through which a feature of the elongated framing member projects partially or completely (e.g., as is the case with framing members 38 and 40a), via a feature of the planar member or an anchor point coupled thereto that projects into a slot formed in the end of an elongated framing member (e.g., as is the case with framing members 42 and 40a, as well as in the arrangement illustrated in FIGS. 2-3). Opposing anchor points are defined along the axis of the elongated framing member such that the axis is substantially normal to the surface of the planar framing member, and such that at least a portion of the elongated framing member is interposed between the opposing anchor points.

(51) FIGS. 15-21 next illustrate an example bed frame utilizing tensioning mechanisms according to another embodiment of the invention. FIG. 15, in particular, illustrates another example anchor point configuration referred to herein as a corner (C) anchor 44 including two substantially perpendicular interlocking slots or features 44a, 44b set at about a 90 degree angle relative to one another, along with an interior slot 44c functioning as a tension cleat. FIG. 16 illustrates C anchor 44 being used as a common anchor point for two tensioning mechanisms, a first including C anchor 44 along with a similarly configured C anchor 46 and a tensioning device 12a (the strap of which is looped through slots or cleats 44c and 46c) to apply tension along a linear axis 4d, and a second including C anchor 44 along with a similarly configured C anchor 48 and a tensioning device 12b (the strap of which is looped through slots or cleats 44c and 48c) to apply tension along a linear axis 4e. C anchors 46, 48 are similar or identical to C anchor 44, and include similarly-configured slots 46a-c and 48a-c. It will be appreciated that C anchors may be manufactured to support intersecting angles other than 90 degrees, and thus may be suitable for use in constructing a wide variety of furniture configurations. C anchor 44, as shown in FIG. 16, provides opposition for opposing C anchors 46 and 48, and thereby provides two channels of compression from tensioning devices 12a and 12b.

(52) FIG. 17 next illustrates a framing member 52 interposed between C anchors 44 and 46. Framing member 52 includes a slot or feature 52a that interlocks with feature 44b of C anchor 44, as well as a slot or feature 52b that interlocks with feature 46b of C anchor 46. As shown in FIG. 18, when tensioning device 12 is looped through slots 44c and 46c of C anchors 44 and 46 while framing member 52 is interlocked with C anchors 44 and 46, a channel of compression is formed by tensioning device 12a to draw C anchors 44 and 46 and framing member 52 together in tension and in an interlocking relationship.

(53) As also illustrated in FIG. 17, it may be desirable in some embodiments to interlock a framing member 52 with multiple C anchors at each end thereof, e.g., using slots or features 52a-52d. Thus, two or more stacked C anchors may be disposed at each end of a framing member to provide additional support in some embodiments.

(54) It should be noted that, in this embodiment, a C anchor effectively serves a dual function as both a framing member and an anchor point. Thus, for example, C anchors 44, 46 and framing member 52 collectively engage one another in an interlocking relationship. Furthermore, framing member 52 is oriented in a generally transverse orientation relative to C anchors 44, 46. Moreover, opposing anchor points, taking the form of slots or tension cleats 44c, 46c, are respectively defined on or otherwise coupled to C anchors 44, 46, such that tensioning device 12 applies tension between these anchor points and draws the C anchors 44, 46 and framing member 52 together under tension in the interlocking relationship.

(55) Now turning to FIG. 19, a complete bed frame may be assembled from components similar to those described above in connection with FIGS. 15-18, including framing member 62 (serving as a headboard), framing members 64 and 66 (serving as side rails), framing member 68 (serving as a footboard), C anchors 44, 46, 48, 50, 54, 56, 58 and 60 and tensioning devices 12a-12h (configured similarly to tensioning device 12 of FIG. 1).

(56) To assemble the sample bed frame, C anchors 44 and 48 may be pressure locked onto framing member 62 using tensioning device 12c, C anchors 54 and 58 may be pressure locked onto framing member 62 using tensioning device 12d, C anchors 46 and 50 may be pressure locked onto framing member 68 using tensioning device 12g and C anchors 56 and 60 may be pressure locked onto framing member 68 using tensioning device 12h. C anchors 44 and 46, and C anchors 54 and 56, may be pressure locked onto framing member 64 using respective tensioning devices 12a and 12b, while C anchors 48 and 50, and C anchors 58 and 60, may be pressure locked onto framing member 66 using respective tensioning devices 12e and 12f, thereby completing assembly of the example bed frame, as illustrated in FIG. 20. In addition, as shown in FIG. 21, when a mattress 70 is placed on the bed frame, and supported by C anchors 44-50, tensioning devices: 12a-12h are all encased inside the interior space between the framing members, and thus effectively hidden from view.

(57) As such, it will be appreciated that the manner by which transversely-oriented framing members are secured to one another in an interlocking relationship and drawn together under tension by a tensioning mechanism are fundamentally similar for each of the example furniture components illustrated in FIGS. 1-21. Additional embodiments utilizing the principles discussed herein, as well as additional features such as bracing, alternate bed configurations and over-forking members, are discussed in greater detail in the aforementioned cross-referenced provisional application, and in particular in FIGS. 18-44 and the accompanying text describing the same, which are expressly incorporated by reference herein.
