摘要： A two-stage lock assembly comprising a multi-element lock tab configured for disposition in a lateral structure of a lock device. The multi-element lock tab may include a body that includes an end on which a first element and a second element are disposed. The first element may extend from the body farther than the second element to enable the first element to be introduced into a receiver prior to the second element. The multi-element lock tab may be configurable in a disengaged configuration in which the first element and the second element are not positioned in a receiver, a first engaged configuration in which the first element is positioned in the receiver and the second element is not, and a second engaged configuration in which the first and the second elements are positioned in the receiver.

摘要： A locking mechanism for a support leg hingedly attached to a support surface. The locking mechanism includes a base, attached to the support surface, with a plurality of angularly spaced, radial teeth, and a coupler, attached to the support leg, having a plurality of angularly spaced, radial teeth configured to mate with the teeth of the base. A selectively releasable engagement mechanism is configured to engage and disengage the teeth of the base with the teeth of the coupler, to allow selective rotation of the support leg between an extended position and a folded position, and to lock the leg in the extended or folded position.
