Abstract: An assembly includes an elongated channel member, a clip and a leg. The clip includes a hook proximate the first end of the clip, a fastener proximate the second end of the clip, and a pivot protrusion disposed between the first and second ends of the clip. The clip is attached to the first end of the elongated channel member. The leg is oriented at a first angle to the elongated channel member and adjacent the first end of the elongated channel member. The leg includes an opening. The hook of the clip is configured for insertion into the opening of the leg. Using the fastener to move the second end of the clip toward a surface of the elongated channel member causes the hook of the clip to rotate about the pivot protrusion, thereby engaging a surface of the leg. A method is described for assembling a structure.

Abstract: An articulating locking mechanism for the locking and unlocking of a shaft member has a housing for mounting to any support surface, including an underside of a table. An operator pulls on a latch actuator to unlock the locking mechanism, thereby allowing a shaft member support to rotate within the housing between a first upright position and a second folded position. To lock the shaft member support into either position, the operator releases the latch actuator, whereby a finger on a latch member is urged by a spring into one of two grooves on the shaft member support, thereby locking the shaft member support into either its first upright position or its second folded position.
