Collapsible portable table

Abstract

An improved collapsible portable table suitable for use in both outdoor and indoor environments and on both regular and irregular surfaces, having a tabletop and a two-part support leg comprised of a main support shaft and a stake in telescopic relationship to each other, and an optional stabilization base removably attachable to the stake. The improved collapsible portable table is easily disassembled for transport and storage with components which can be conveniently stored within themselves, is both light weight and durable, comprises safety features to prevent injury to users, and is easy and inexpensive to manufacture.

1 . A table, comprising
 a tabletop, said tabletop being substantially planar and being constructed of a rigid material, said tabletop having any suitable size and shape;   a main support shaft, said main support shaft being substantially cylindrical and hollow, having a first end, a second end, an outer wall, and an inside diameter, said main support shaft being constructed of a rigid material;   a stub, said stub suitably adapted to removably secure the tabletop to the first end of the main support shaft;   a stake, said stake being substantially cylindrical and having a first end and a second end and an outside diameter, said outside diameter of said stake being just slightly less than the inside diameter of the main support shaft, said stake suitably adapted to be at least partially inserted into the main support shaft at the second end of the main support shaft and removably secured thereto, with the second end of said stake being tapered to a blunted point, with said stake being constructed of a rigid material;   a stabilization base, said stabilization base being substantially planar and being constructed of a rigid material, said stabilization base having a top surface and a bottom surface, said bottom surface of said stabilization base having a circumferential rim; and   a collar, said collar suitably adapted to removably secure the stabilization base to the stake;   whereby the main support shaft in combination with the stake inserted at least partially into the main support shaft and secured thereto, and optionally in combination with the stabilization base, is suitably adapted to support the table in a substantially upright orientation.   
   
   
       2 . The table of  claim 1  wherein
 the tabletop comprises a central threaded aperture; and   the stub is substantially cylindrical and has a first end, a second end, and an outside diameter,
 said first end being threaded and suitably adapted to be threaded into the central threaded aperture of the tabletop thereby removably securing said first end of the stub to the tabletop, and 
 said outside diameter of the stub being just slightly less than the inside diameter of the main support shaft, said second end of the stub suitably adapted to be at least partially inserted into the main support shaft at the first end of the main support shaft and removably secured thereto. 
   
   
   
       3 . The table of  claim 2  further comprising
 a first threaded set screw; and   the main support shaft further comprising an upper threaded aperture at the first end of the main support shaft, said upper threaded aperture being substantially perpendicular to the outer wall of the main support shaft and passing completely through the outer wall of the main support shaft;   wherein the first threaded set screw is suitably adapted to be threaded into the upper threaded aperture of the main support shaft completely through the outer wall of the main support shaft, such that the first threaded set screw when threaded into the upper threaded aperture of the main support shaft engages the stub proximate to the second end of the stub when the stub is at least partially inserted into the main support shaft, thereby removably securing the stub to the main support shaft.   
   
   
       4 . The table of  claim 1  further comprising
 a second threaded set screw; and   the main support shaft further comprising a lower threaded aperture at the second end of the main support shaft, said lower threaded aperture being substantially perpendicular to the outer wall of the main support shaft and passing completely through the outer wall of the main support shaft;   wherein the second threaded set screw is suitably adapted to be threaded into the lower threaded aperture of the main support shaft completely through the outer wall of the main support shaft, such that the second threaded set screw when threaded into the lower threaded aperture of the main support shaft engages the stake when the stake is at least partially inserted into the main support shaft, thereby removably securing the stake to the main support shaft.   
   
   
       5 . The table of  claim 1  wherein
 the stabilization base comprises a central threaded aperture; and   the collar is substantially cylindrical and hollow, having a first end, a second end, an outer wall, and an inside diameter,
 said first end of the collar being threaded and suitably adapted to be threaded into the central threaded aperture of the stabilization base thereby removably securing said first end of the collar to the stabilization base, and 
 said inside diameter of the collar being just slightly larger than the outside diameter of the stake; 
   whereby the stake is suitably adapted to be at least partially inserted into the collar and removably secured thereto.   
   
   
       6 . The table of  claim 5  further comprising
 a third threaded set screw; and   the collar further comprising a threaded aperture at the second end of the collar, said threaded aperture being substantially perpendicular to the outer wall of the collar and passing completely through the outer wall of the collar;   wherein the third threaded set screw is suitably adapted to be threaded into the threaded aperture of the collar completely through the outer wall of the collar, such that the third threaded set screw when threaded into the threaded aperture of the collar engages the stake when the stake is at least partially inserted into the collar, thereby removably securing the collar to the stake.   
   
   
       7 . The table of  claim 1  wherein the stake may be completely contained within the main support shaft and secured therein. 
   
   
       8 . The table of  claim 1  wherein
 the tabletop, the main support shaft, the stub, the stake, the stabilization base, and the collar are constructed of one of the following group of materials: aluminum, stainless steel, wood, plastic.
