Abstract
A collapsible, portable shelving unit that is useful within tents and the like when one is camping. The device is easy to pack and carry and is lightweight but will hold a fair amount of weight when in use. There is no requirement for supporting the shelving unit to posts or trees or the like, as the device is self-supportable, even when it contains various objects on the shelving. It is especially useful for tent camping.
Claims
1. A collapsible outdoor shelving unit, said unit comprising: at least one shelf, each said shelf having a back edge, a top surface, a side surface and two ends; a collapsible support shaft, said collapsible support shaft having a top end and a bottom end, said top end terminating in a handle, said bottom end terminating in a pointed tip; each said shelf having an opening near said back edge and essentially centered between said two ends of said shelf to allow entry of said shaft; a retainer for each said shelf consisting of a threaded compressible sleeve and a threaded nut for said compressible sleeve wherein the compressible sleeve is molded into a bottom of said shelf.
2. A collapsible outdoor shelving unit as claimed in claim 1, wherein said shaft consists of one piece.
3. A collapsible outdoor shelving unit as claimed in claim 1, wherein said shaft consists of at least two pieces.

DETAILED DESCRIPTION OF THE DRAWINGS
(9) FIG. 1 is a view in perspective of the collapsible outdoor shelving 2 of this invention showing two shelves 4 and friction grommets 28 as the retaining means for the shelves 4. The shelves 4 have a back surface 6, a top surface 8 and a side surface 10. The shelves 4 also have a first end 12 and a second end 14.
(10) There is also a support shaft 16 that has a top end 18 and a bottom end 20. The top end 18 terminates into a handle 22 and the bottom end terminates into a point 24.
(11) Each shelf 4 has an opening 26 through it, near the back edge 6, and is essentially centered between the two ends 12 and 14 of the shelf 4 to allow entry of the shaft 16. There are various embodiments for a means of retaining the shelves 4 on the shaft 16.
(12) FIG. 2 shows the shaft 16 as being threaded in predetermined positions and the retaining means are threaded nuts 32. The retaining means can be a threaded shaft with threaded nuts 32 that hold the shelves in place with respect to where the threaded nuts are positioned on the shaft 16.
(13) FIG. 3 is a partial view of a threaded insertable bolt 34 as the retaining means. Here the shelves 4 are retained by the insertable threaded bolt 34 that is tightened against the shaft 16.
(14) FIG. 4 is a partial view of a shaft collar 36 as the retaining means. The shelves 4 are retained by the shaft collar 36 that is tightened against the shaft 16.
(15) FIG. 5 shows a hex bolt 38 through the opening 50 through the side surface 10 of the shelf 4 to the shaft 16, as the retaining means. This embodiment also has openings 46 in the shaft and in the side surface of the shelf 4 to retain the shelf 4 with the hex bolt 38.
(16) FIG. 6 shows a hitch pin 40 through the opening 50 through the side surface 10 of the shelf 4 to the shaft 16 as the retaining means. The hitch pin 40 passes through the opening 50 through in the shelf side edge 10 to shaft 16 as the retaining means.
(17) Another form of fastening means for this invention is a compressible plastic post 51 shown in FIGS. 7A and 7B. Designation 3 is a threaded nut that fits the compressible plastic post 51 and compresses the post 51 as it is wound onto the compressible plastic post 51. This is possible because of the open slit 52 in the compressible plastic post 52. The compressible plastic post 52 can be molded in the bottom of the shelf 4 during molding of the shelf 4 or it can be a plug that is inserted in an opening prior to insertion of the post.
