초록 ▼

The present invention in its preferred embodiment, is a collapsable and automatically assemblable shock corded tripod stand (10) constructed of a tetrahedral spider element (18) which acts as the interface between three support legs (12,14 and 16) and a vertical member (20). The legs (12, 14, and 16) and the vertical member (20) are formed from multiple first tubes (22) and second tubes (24). The force which holds the device in place and provides the impetus for the automatic assembly is tension provided by a first shock cord (48) and a second shock cord (50). The first shock cord (48) passes from the outermost tube (24) of the first leg (12), through the spider (18), and extends to the outermost tube (24) of the second leg (14). The second shock cord (50) passes from the outermost tube (24) of the third leg (16), through the spider (18), and extends to the uppermost tube (64 ) of the vertical member (20). When the stand (10) is disassembled, the tubes (22 and 24) are all in a position parallel to each other and bound by a strap (62). Assembly is accomplished by grasping the uppermost tube (64) and releasing the strap (62). Given sufficient clearance, gravity and the tension in the shock cords (48 and 50) will cause the vertical member (20) and the legs (12, 14, and 16) to serially assemble. Objects are attached to the stand (10) by means of one or more attachment clamps (68). The attachment clamps (68) can be affixed to either the vertical member (20) or the legs (12,14, and 16). The clamps (68) are held in place by a frictional gate lock, which is released by changing the positioned angle relative to the stand (10), which allows the positioning of the clamps (68) to be changed with one hand. The primary usage of the invention is as a photographic lightstand.
