The drawings are intended to be read together with the specification and are to be construed as a portion of the entire “written description” of this invention as required by 35 U.S.C. §112.

(22) In one embodiment of the present invention presented in FIGS. 1-12, a collapsible support apparatus 100 with hinged multi-tier shelves and separable buckle hinges provides a television support structure having multiple tiers of shelves, including a folding upper shelf 102 that is designed to support a television and a middle and lower shelf that support other objects pertinent to the television or shelf related materials known in the art.

(23) As referenced in FIG. 1, the collapsible support apparatus 100, hereafter “apparatus 100”, is also configured to collapse and expand through pivotal articulation about at least one separable buckle hinge 124a-f and at least one simple hinge 138a-h. Various crossbars, support members, and sloped dispositions work to enhance lateral stability and structural integrity for support of a television or similarly weighted object.

(24) Looking now at FIG. 2, the apparatus 100 provides a rigid, multi-configurable support structure for supporting a television or other entertainment device, such as a flat screen television, a stereo, a computer, or a video system. The apparatus 100 easily collapses for stowage, but also reversibly and easily expands for use without requiring tools or special skill. In some embodiments, the apparatus 100 is a folding television stand that can be assembled with minimal tools or skill set.

(25) As referenced in FIG. 3, the apparatus 100 utilizes variously disposed and sized shelves and elongated supportive bars and members that interconnect about hinges to construct the laterally stable and pivotally detachable configurations described below. In one possible embodiment, the apparatus 100 may have a generally trapezoidal shape when viewed from above, and a wide base for supporting the weight of the television. Though in other embodiments, the apparatus 100 may also take other shapes when viewed from above, such as, a rhombus, a cube, a pyramid, an oval, or a rectangle. Suitable materials for the apparatus 100 may include, without limitation, wood, metal, fiberglass, rigid polymers, bamboo, and cardboard.

(26) The apparatus 100 comprises an upper shelf 102 that supports the television, or similar object. The apparatus 100 further comprises a middle shelf 104 and lower shelf 106 disposed in a stacked arrangement beneath the upper shelf 102. The apparatus 100 further comprises strategically positioned separable buckle hinges 124a-f that pivot up to 90° and separate, so as to enable both pivotal articulation and detachable attachments between the components of the apparatus 100. This capacity to separate hinged connection points facilitates collapsibility and assemblage of the apparatus 100.

(27) Further, at least one simple hinge 138a-h may also be used to enable pivotal articulation, solely for pivotal articulation. The apparatus 100 further comprises elongated crossbars, support members, connecting bars, and a rectangular frame that hingedly interconnect through the separable buckle hinge and the simple hinge 138a-h to easily move between an expanded position 174 for supporting the television, and a collapsed position 172 for stowage and portability.

(28) As referenced in FIG. 4A, the apparatus 100 comprises an upper shelf 102, a middle shelf 104, and a lower shelf 106 that are arranged in a stacked, spaced-apart relationship. The upper shelf 102 is arranged generally above the middle shelf 104 and the lower shelf 106. The upper shelf 102, the middle shelf 104, and the lower shelf 106 are generally flat and elongated, so as to support objects, such as a television. In one embodiment, the shelves are elongated and flat. The upper shelf 102 may be fabricated from glass. Though any of the shelves 102, 104, 106 may be fabricated from materials, including, without limitation, glass, wood, metal, plastic, granite, and fiberglass.

(29) Looking now at FIGS. 4A and 4C, the apparatus 100 may include an upper crossbar 108 defined by a pair of upper ends 110a, 110b. The upper crossbar 108 is configured to at least partially support the upper shelf 102. In some embodiments, a pair of protruding members 168a, 168b extend from the upper crossbar 108 to help support the upper shelf 102. The apparatus 100 further provides a middle crossbar 112 defined by a pair of middle ends 114a, 114b. The middle crossbar 112 configured to at least partially support the middle shelf 104. The apparatus 100 further provides a lower crossbar 116 defined by a pair of lower ends 118a, 118b. The lower crossbar 116 is configured to at least partially support the lower shelf 106. The crossbars 108, 112, 116 are disposed in a generally horizontal, spaced-apart relationship.

(30) Looking now at FIGS. 5A, 5B, and 5C, the apparatus 100 includes a first vertical support member 120 that fixedly attaches in a generally perpendicular disposition to a respective end of the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116. The first vertical support member 120 is disposed to slope between the upper crossbar 108 and the lower crossbar 116, whereby the sloped disposition helps support the upper shelf 102. The slope of the first vertical support member 120 extends at an outward angle towards the upper shelf 102. This sloped disposition reduces direct axial forces on the first vertical support member 120 from the weight of the television on the upper shelf 102.

(31) Across from the first vertical support member 120 is a second vertical support member 122 that fixedly attaches in a generally perpendicular disposition to a respective end of the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116. The second vertical support member 122 is disposed to slope between the upper crossbar 108 and the lower crossbar 116, whereby the sloped disposition helps support the upper shelf 102. The slope of the second vertical support member 122 extends at an outward angle towards the upper shelf 102. This sloped disposition reduces direct axial forces on the second vertical support member 122 from the weight of the television on the upper shelf 102.

(32) Looking now at FIG. 8A, the apparatus 100 may include at least one separable buckle hinge 124a-f configured to enable hinged and detachable connections. Specifically, the separable buckle hinge 124a-f is used to fasten, connect, and pivot multiple sections of the apparatus 100 relative to each other. The separable buckle hinge 124a-f is configured to separate into two sections that enable both pivotal articulation and separation by the apparatus 100. In one embodiment, the at least one separable buckle hinge comprises six separable buckle hinges 124a, 124b, 124c, 124d, 124e, 124f.

(33) As shown in FIG. 8B, the separable buckle hinge 124a-f may include a lip 126 and a latching member 128. In one exemplary embodiment, the lip 126 is attached to the middle crossbar 112, and the latching member 128 is fastened to the frame 156. The latching member 128 pivotally fastens and detaches from the lip 126 in a secure but adjustable manner. In one embodiment, the lip 126 enables passage of at least one screw 136a, 136b for fastening the lip 126 to the apparatus 100.

(34) Furthermore, the latching member 128 comprises a mounting panel 130, a lever 132, and a catch 134. The lever 132 of the latching member 128 is configured to pivot on a fulcrum, so as to pivotally move the catch 134 and engage the lip 126. In this manner, the lip 126 retains and holds the latching member 128 for detachable fastening. In one embodiment, the separable buckle hinge 124a-f pivots up to 90°. In one embodiment, the mounting panel 130 of the latching member 128 enables passage of the at least one screw 136a, 136b for fastening the mounting panel 130 to the apparatus 100. In another embodiment, the latching member 128 pivots on a fulcrum. In yet another embodiment, the catch 134 is defined by a generally square shape.

(35) In operation of the separable buckle hinge 124a-f, the lever 132 is configured to pivot on the fulcrum selectively, to and from the lip 126, such that the catch 134 engages and disengages from the lip 126. Once the catch 134 clasps onto the generally protruding lip 126, a force is applied to the lever 132 away from the lip to forcibly clamp the respective sections of the apparatus 100 together. The direction of the lever 132 may then be reversed to disengage the catch 134 from the lip 126, and thereby enable separation of the respective sections of the separable buckle hinge 124a-f.

(36) In another type of hinging mechanism shown in FIG. 7A, the apparatus 100 utilizes at least one simple hinge 138a-h that is configured to enable hinged connections between the frame 156 and the connecting bars 144a-b, 150a-b of the apparatus 100. However, unlike the separable buckle hinge 124a-f, the simple hinge 138a-h does not separate. The simple hinge 138a-h comprises a first hinge side 140 that pivotally joins a second hinge side 142, as illustrated in FIG. 7B. In one embodiment, the simple hinge 138a-h pivots up to 90°. In one embodiment, the at least one simple hinge 138a-h comprises eight simple hinges 138a, 138b, 138c, 138d, 138e, 138f, 138g, 138h.

(37) In some embodiments, the apparatus 100 may include a pair of first connecting bars 144a, 144b disposed in a generally parallel, spaced apart relationship. The first connecting bars 144a, 144b are defined by a first front end 146 and a first rear end 148. The first front end 146 for the first connecting bars 144a, 144b is pivotally carried by the upper crossbar 108 and the lower crossbar 116. The first connecting bars 144a, 144b are coupled to the upper crossbar 108 and the lower crossbar 116 about the simple hinge 138a-h.

(38) As illustrated in FIGS. 6A and 6B, the hinging upper shelf 102 fixedly joins a welded metal panel 166 at the upper crossbar 108 and the first front end 146 of the first connecting member 144a, 144b. In another embodiment, a first reinforcement bar 170a extends between the first front end 146 of the pair of first connecting bars 144a, 144b. In the expanded position 174, the first reinforcement bar 170a runs parallel, and hingedly joined with the first frame member 162 of the frame 156. The first reinforcement bar 170a enhances the structural integrity of the apparatus 100, especially in the expanded position 174.

(39) Similarly, the apparatus 100 comprises a pair of second connecting bars 150a, 150b disposed in a generally parallel, spaced apart relationship. The second connecting bars 150a, 150b are defined by a second front end 152 and a second rear end 154. The second front end 152 for the pair of second connecting bars 150a, 150b is pivotally carried by the upper crossbar 108 and the lower crossbar 116. The pair of second connecting bars 150a, 150b are coupled to the upper crossbar 108 and the lower crossbar 116 about the at least one simple hinge 138a-h.

(40) In one embodiment, a welded metal panel 166 fixedly joins the upper crossbar 108 with the second front end 152 of the second connecting bar 150a, 150b. In another embodiment, a second reinforcement bar 170b extends between the second front end 152 of the pair of second connecting bars 150a, 150b. In the expanded position 174, the second reinforcement bar 170b runs parallel, and hingedly joined with the second frame member 164 of the frame 156. The second reinforcement bar 170b enhances the structural integrity of the apparatus 100, especially in the expanded position 174.

(41) Looking ahead to FIG. 7A, the apparatus 100 may include a generally rectangular frame 156. The frame 156 provides structural integrity to the apparatus 100 and is defined by an upper frame member 158, a lower frame member 160, a first frame member 162, and a second frame member 164 that form the rectangular shape. The first frame member 162 is pivotally carried by the pair of first connecting bars 144a, 144b about the separable buckle hinge 124a. In this manner, the frame 156 may pivot up to 90°, and separate from the first connecting bars 144a, 144b while moving to the collapsed position 172. The second frame member 164 is pivotally carried by the pair of second connecting bars 150a, 150b about the simple hinge 138a-h. In this manner, the frame 156 may pivot up to 90°, yet simple separation is not possible with the simple hinge 138a-h.

(42) In this manner, pivotal articulation of the apparatus 100 between a collapsed position 172 and an expanded position involves pivoting the first connecting bars 144a, 144b and the frame 156 between extended and coplanar configurations against the crossbars 108, 112, 116. The separable buckle hinge 124a-f also works to detach the first connecting bars 144a, 144b from the first frame member 162 of the frame 156. The shelves 102, 104, 106 are also detached and attached as needed.

(43) As shown in FIG. 4B, the pair of first connecting bars 144a, 144b pivot about the separable buckle hinge 124a-f to extend at an angle between the first vertical support member 120 and the first frame member 162 while in an expanded position 174. Conversely, the pair of first connecting bars 144a, 144b are pivoted coplanar to the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 while in a collapsed position 172.

(44) Similarly, the pair of second connecting bars 150a, 150b pivotally articulate about the simple hinge 138a-h to extend at an angle between the second vertical support member 122 and the second frame member 164 while in an expanded position 174. The pair of second connecting bars 150a, 150b are pivoted coplanar to the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 while in a collapsed position 172.

(45) Looking back at FIG. FIG. 4C, the pair of first connecting bars 144a, 144b and the pair of second connecting bars 150a, 150b extend at an outward angle from the frame 156 to the upper crossbar 108 and the lower crossbar 116. This sloped disposition creates lateral stability for the apparatus 100, as torque and axial forces are dispersed along the slope. The capacity to provide lateral stability is especially significant since the apparatus 100 supports generally heavy televisions and entertainment devices. The transverse crossing of the connecting bars fills a space in the central region of the apparatus 100, which restricts undesirable torqueing, bending, and warping of the frame and crossbars that make up the apparatus 100.

(46) Further, the pair of connecting bars 144a-b, 150a-b pivot towards the crossbars 108, 112, 116 and thereby form a coplanar arrangement with the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 in the collapsed position 172. In the collapsed position 172, structural integrity is not as primary a concern. However, the compactness of the coplanar configuration enhances stowage and portability of the apparatus 100.

(47) Additionally, the frame 156 is pivoted to a coplanar, spaced-apart relationship with the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 while in the expanded position 174. To achieve the collapsed position 172, the frame 156 is pivoted between the pair of first connecting bars 144a, 144b and the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116. Further, the second frame member 164 detaches from the pair of second connecting bars 150a, 150b through the separable buckle hinge 124a-f while pivoting to the collapsed position 172 (FIG. 9).

(48) In one exemplary configuration shown in FIG. 10, the pair of first connecting bars 144a, 144b are disposed to extend at an angle between the upper crossbar 108 and the first frame member 162 while in an expanded position 174. Conversely, the pair of first connecting bars 144a, 144b move coplanar to the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 in the collapsed position 172. This forms a substantially flat configuration that is useful for stowage and portability of the apparatus 100.

(49) In another exemplary configuration shown in FIG. 11, the pair of second connecting bars 150a, 150b are disposed to extend at an angle between the middle crossbar 112 and the second frame member 164 while in an expanded position 174. Conversely, the pair of second connecting bars 150a, 150b move coplanar to the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 while in the collapsed position 172. This forms a substantially flat configuration that is efficacious for stowage and portability of the apparatus 100.

(50) In another exemplary configuration shown in FIG. 12, the frame 156 is disposed in a coplanar, spaced-apart relationship with the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 while in the expanded position 174. Conversely, the frame 156 is disposed between the pair of first connecting bars 144a, 144b and the upper crossbar 108, the middle crossbar 112, and the lower crossbar 116 while in the collapsed position 172. This forms a substantially flat configuration that is efficacious for stowage and portability of the apparatus 100.

(51) Thus, the apparatus 100 is specially configured so that the connecting bars 108, 112, 116, 144a-b, 150a-b and frame ends 162, 164 are hingedly and detachably connected together so that they may be quickly assembled and also disassembled and returned to the collapsed position 172. The collapsed position 172 is useful for stowage and portability of the apparatus 100.

(52) Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
