发明名称 Leg structure for a folding table
摘要 Disclosed is a leg structure for a folding table which prevents a small child from being dangerously clamped by the table legs when the table tilts over and the legs become folded to a table top of the table. The table legs include a first leg pair having two integrally formed legs and a second leg pair formed of a U-shape upper frame, a middle connecting frame, and a lower leg frame. Upper ends of the integrally formed legs and the U-shaped upper frame are pivotally connected to a bottom side of the table top. The lower leg frame is pivotally connected to the integrally formed legs. The middle connecting frame is pivotally connected at upper ends to the U-shaped upper frame and at lower ends to the lower leg frame. When the two leg pairs are extended from the table top, the middle connecting frame abuts against a lower crossbar on the U-shaped upper frame and an upper crossbar on the lower leg frame to define a maximum open angle to which the two leg pairs can be extended relative to one another.
