In one embodiment, shelf 10 is an L-shaped configuration wherein bottom plate 20 extends from front surface 44 of back plate 18 at a first angle 48. In one embodiment, first angle 48 is approximately 90 degrees.

In one embodiment, holes 40 and 42 are provided through back plate 18, extending from front face 44 to back face 46. In one embodiment, two attachment holes 40 are located near top edge 19. In another embodiment, attachment holes 40 are located along side edges 22, between top edge 19 and bottom edge 17. In one embodiment, holes 40 provide for attaching a carrying strap, shoulder strap, or other transporting mechanism (illustrated in FIG. 11). In one embodiment, securing holes 42 are provided near bottom edge 17 of back plate 18. In one embodiment, securing holes 42 are used for securing other elements of portable stand 100, discussed below, to shelf 10 during transport or storage.

As illustrated in FIG. 4, a mounting element 50 is provided on back surface 46. In one embodiment, mounting element 50 is suitable for mating with first end 28 of tripod 16. In one embodiment, mounting element 50 includes nuts, bolts, pivot legs, brackets or other means to facilitate assembly with tripod 16 when the portable stand 100 is assembled for use. Mounting element 50 provides a pivotable connection to tripod 16. Mounting element 50 is configured to be suitable for attachment to the vertical post of any standard tripod. Any standard mounting configuration is acceptable.

FIGS. 5A and 5B illustrate side views of shelf extension 12 according to one embodiment. In one embodiment, each of the two elongated flanges 50 include a connection point 26 and bracket 24, respectively. In one embodiment, brackets 24 include sliding portion 60, stop 62, and fixed portion 64. Fixed portion 64 is fixedly coupled to flange 50. In one embodiment, stop 62 extends away from flange 50 and joins fixed portion 64 to sliding portion 60 in a z-shaped configuration. In one embodiment, connection point 26 is included on elongated flange 50. In one embodiment, connection point 26 is a hole positioned on the opposite end of elongated flange 50 with respect to brackets 24.

FIGS. 6A and 6B illustrate perspective views of shelf extension 12. Shelf extension 12 includes two elongated flanges 50 that are connected along elongated side 52 at an angle 54 equal to first angle 48 on shelf 10. In one embodiment, the corners 56 of elongated flanges 50 which are not connected along elongated side 52 are rounded or smoothed for safety in handling. FIG. 7 is an end view of shelf extension 12. In one embodiment, the width of brackets 34 extends to be approximately equal to the width of elongated flanges 50.

FIGS. 8-10 illustrate embodiments of arm 14. In one embodiment, arm 14 is an elongated plate including first end 70 and opposite second end 72. In one embodiment, first end 70 is flat and includes connection 76. In one embodiment, connection 76 is a hole which corresponds to, and is capable of connecting to at least one of connection point 26 of shelf extension 12. In one embodiment, beveled portion 74 extends from first end 70 and is slightly angled between horizontal planes of the first end 70 and second end 72. In one embodiment, extending from beveled portion 74, toward second end 72, sides 78 are bent slightly inward along center line or ridge 80.

FIG. 11 illustrates portable stand 200 configured for transport or storage according to one embodiment. In one embodiment, portable stand 200 includes shoulder strap 92 and flexible connectors 90. As discussed above, holes 40 are included in back plate 18 for attachment of a carrying strap as well as holes 42 for attachment of flexible connectors 90 which secure the shelf extension 12, arm 14, tripod 16 or other elements to the shelf 12 during transport or storage. In one embodiment, the portable stand 200 may be easily transported with or without the additional use of a carrying bag.

In one embodiment, flexible connectors 90 secure tripod 16 to back plate 18 by connecting to holes 42. In another embodiment, flexible connectors 90 are removably secured with one end at holes 42 and an opposing end removably secured at side edge 22. In one embodiment, flexible connectors 90 are extendable straps of elastic material with hooks at both ends, although other suitable attachment devices may be used. In one embodiment, holes 42 are positioned such that when tripod 16 is secured to back plate 18, tripod 16 is positioned on top of bottom plate 20. In one embodiment, tripod 16 is a collapsible stand and is secured to back plate 12 in its collapsed state. In one embodiment, legs 30 are collapsed or retracted parallel to telescoping rod 34. In another embodiment, additional items may be secured by flexible connectors 90 to back plate 18. In one embodiment, tripod 16 in a collapsed state, shelf extension 12 and arm 14 are each approximately the length of bottom edge 17.
