Abstract: A two-way caster bench comprises a front chair frame, a middle chair frame and a rear chair frame. The front chair frame is a U-shaped frame having a predetermined number of casters installed underneath, whose free ends are pivotally connected with the middle chair frame. The middle chair frame is composed of two U-shaped frames connected by a pair of connecting bars, with the free ends facing outwardly. One U-shaped frame is for a pivotal connection to the front chair frame, and another is for a pivotal connection to the rear chair frame. The rear chair frame is also a U-shaped frame having a predetermined number of casters installed underneath, the bottom of which is provided with a transverse bar for supporting the middle chair frame as it is folded toward the rear chair frame. Each of the chair frames is provided with a cushion.

Abstract: A slippage-preventing device for tubular jack handle consists of a jack handle stand that is provided with a movable bar extending into the inner wall of an insertion hole therein. A tubular handle has a front end, which is provided with a locking groove and an angled-rim tip. As the tubular handle is inserted into the insertion hole, the angled-rim tip at the front end firstly pushes the movable bar aside, and as the insertion is completed, the movable bar is driven back resiliently to lock the tubular handle at the locking groove thereon. The locking mechanism can be removed by pulling outward the movable bar. This mechanism facilitates the assembly and disassembly of the tubular handle and the jack handle stand.
