Two-stage lock assembly

A two-stage lock assembly configured to prevent structure collapse due to an insufficiently rotated leg assembly, the leg assembly including a receiver, the leg assembly movable between a collapsed position, a first extended position, and a second extended position, the 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 including a body with an end, the end including a first outwardly extending element forming a first portion of the end and a second outwardly extending element forming a second portion of the end, the first portion of the end and the second portion of the end forming different portions of the end of the body,
• wherein:
• the multi-element lock tab is configurable in a disengaged configuration, a first engaged configuration, and a second engaged configuration;
• the first element extends from the body farther than the second element to enable the first element to be introduced into the receiver prior to the second element;
• and
• the disengaged configuration occurs when the first element and the second element are not positioned in the receiver, the first engaged configuration occurs when the first element is positioned in the receiver and the second element is not positioned in the receiver, and the second engaged configuration occurs when the first and the second elements are positioned in the receiver.

A table comprising:

• a tabletop;
• a frame attached to the tabletop;
• and
• a leg assembly connected to the frame, the leg assembly comprising:
• a support element rotatably coupled to the frame, the support element rotatable between a first position and a second position;
• a receiver disposed in the support element;
• a translation mechanism translating along a portion of the support element as the support element rotates between the first position and the second position;
• and
• a two-stage lock assembly including a lock tab with a first element and a second element, the first element and the second element extending in an outward direction from the body, the two-stage lock assembly including a disengaged configuration in which the translation mechanism is not fixed relative to the support element and the first element and the second element are not disposed in the receiver, a first engaged configuration when the support element is rotated away from the tabletop a first amount and the first element of the two-stage lock assembly is disposed in the receiver and the second element is not disposed in the receiver, and a second engaged configuration when the support element is rotated away from the tabletop a second amount and the first element and the second element of the two-stage lock assembly are disposed in the receiver;
• wherein the leg assembly is configured such that the disengaged configuration occurs when the leg and the end structure is disposed between an angle of about zero degrees to a first engagement angle of about seventy degrees at which the first element is introduced to the receiver;
• wherein the first engaged configuration occurs when the leg and the end structure are positioned in a range from the first engagement angle and a second engagement angle of about ninety degrees;
• and
• wherein the second engaged configuration occurs when the leg and the end structure are positioned at the second engagement angle at which the second element enters the receiver.
