Abstract
The present invention relates to a collapsing jack stand for lifting off road vehicles, heavy equipment, boats, recreational vehicles, trailers, etc. The invention has a saddle for receiving an axel of a piece of equipment that is to be lifted by the stand. The saddle is adjustable in height and is supported above the ground by an upright member mounted on a base, with a brace member helping to support the upright member on the base. The collapsing jack stand is designed to be pivoted downward and folded into a flattened configuration when not in use, making it easy to store in a limited space. Only one bolt must be removed to collapse the jack stand.

A collapsible jack stand for lifting vehicles and equipment, the jack stand comprising:
- (a) a base;
- (b) an adjustable height saddle for receiving therein an axel of a piece of equipment that is to be raised upon the jack stand;
- (c) an upright tube forming aligned holes and having an upper end for supporting the saddle and a lower end secured to the base via an upright tube bolt,
- said upright tube bolt maintaining said upright tube in a vertical orientation only so long as said upright tube is secured to said base by said upright tube bolt;
- (d) a height adjusting bolt that passes through the aligned holes formed in the upright tube;
- (e) a telescoping lower tube extending from the adjustable height saddle, wherein the height of the saddle can be adjusted by the height adjusting bolt that passes through aligned holes formed in the upright tube and also in the telescoping lower tube;
- and
- (f) a brace tube for supporting the upright tube on the base, the brace tube having an upper first end and a lower second end, wherein:
- (1) the upper first end of the brace tube pivotally attaches by an upper brace bolt to an upper brace bracket provided on a rear side of the upright tube;
- (2) the lower second end of the brace tube pivotally attaches by a lower brace bolt to a lower brace bracket provided on the rear end of the base;
- and
- (3) the jack stand may be collapsed by removing the upright tube bolt from the aligned hole in the upright tube.
A collapsible jack stand for supporting vehicles and equipment, the jack stand comprising:
- (a) a base, said base having a top containing a brace bracket;
- (b) a brace tube pivotally attached to said base at a first end;
- (c) an upright tube pivotally attached to said brace tube at a second end of said brace tube, said upright tube pivotable between a horizontal and a vertical orientation,
- said upright tube having an upper end and a lower end,
- said upper end of said upright tube having a pair of aligned height adjusting holes, and,
- said lower end of said upright tube having a pair of aligned locking holes;
- (d) a telescoping tube having a lower end sized to be slideable within said upright tube, said telescoping tube lower having a lower end with a plurality of pairs of aligned adjusting holes;
- (e) a saddle affixed to an upper end of said telescoping tube;
- (f) a height adjusting bolt sized to be passed through said pair of height adjusting holes in said upright tube and through one of said plurality of pairs of adjusting holes in said telescoping tube, thereby locking said saddle at a predetermined height above said upright tube;
- and
- (g) an upright tube bolt sized to pass through said aligned locking holes, said upright tube bolt
- engaging said brace bracket and locking said upright tube in a vertical orientation when said upright tube is pivoted into said vertical orientation and said upright tube bolt is passed through said aligned locking holes, and,
- allowing said upright tube to be rotated into said horizontal position for storage when said upright tube bolt is not engaged with said base bracket.
