发明名称 TELESCOPICALLY COLLAPSIBLE TABLE LEG
摘要 An adjustable table leg structure includes an upper leg connected to the table top and a leg extension or lower leg portion which is telescopically reciprocable within the upper leg to afford height adjustment. The extension leg is held in the adjusted position by a spring biased pawl which is pivoted on the exterior of the upper leg and has a terminal tooth which projects through a slot in the upper leg for engagement with any one of a plurality of vertically spaced locking apertures in the leg extension. The tooth is released from engagement by manual pressure on an arm pivoted to the pawl. The tooth is locked in engagement by pivoting the arm to locate a blocking tab on the arm between the pawl and the upper leg to prevent movement of the pawl and thus provide secure support.
