Abstract
A floor lamp tripod stand includes a socket fastened to a support arm of a floor lamp by a tightening up screw, three legs respectively and pivotably connected to said socket by a pivot pin and a clamp for supporting said support arm on a floor, and three locking plates for locking said legs in any of a series of angular positions on said socket relative to said support arm. Each leg has a top end pivoted to a respective pair of symmetrical wings on the socket and a round rod in an oval hole on the top end retained in either of a series of locating notches on each wing by a spring plate and the respective locking plate. Pressing a finger press portion on either locking plate causes the round rod to be moved from one locating notch to another for permitting the respective leg to be adjusted to any of a series of angular positions on the socket relative to the support arm of said floor lamp.
