  • Patent number: 4761092
    Abstract: A locking mechanism for a telescoping support, such as a tripod leg, which includes an outer tubular section and a slidable inner tubular section is disclosed. The locking mechanism includes a U-shaped mounting bracket conforming to the cross-sectional shape of the outer tubular section and is held against sliding movement along the outer section by lip portions bent outwardly on either side of the bracket. The bracket is further retained against separation from the outer tubular section by a camming lever pivotably mounted between the two arms of the bracket on the side of the leg section opposite the base portion of the bracket, thereby closing the opening of the bracket. The camming lever is pivotable for cammingly engaging the inner tubular section through a window opening formed in the outer tubular section, thereby to lock the two sections against telescoping movement.

  • Patent number: 4609174
    Abstract: A folding easel has three telescoping legs, leg locks for locking each of the legs at arbitrarily extended positions, two tie-bars each hinged at one end to an axle supported on a corresponding leg lock, one tie-bar being snap-engageable to an axle on a third leg lock, the remaining tie-bar being snap-engageable to an intermediate point of the first tie-bar to form a T tie-bar arrangement for maintaining the three legs in fixed spaced apart relationship and usable as a shelf for paint boxes or the like, the tie-bars being readily disengageable without removal of fasteners for folding together of the three legs.
