Abstract
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.
Claims19
A table comprising:
- a tabletop;
- a frame attached to the tabletop;
- and
- a leg assembly comprising:
- a support element rotatably coupled to the frame;
- a translation mechanism retained relative to the support element and the frame, the translation mechanism configured to translate along a portion of the support element as the support element rotates relative to the frame
- a receiver disposed in the support element;
- and
- a two-stage lock assembly including a multi-element lock tab, the multi-element lock tab comprising:
- a body;
- a first element;
- and
- a second element;
- wherein, in a disengaged configuration, the translation mechanism is not fixed relative to the support element;
- wherein, in a first use configuration the support element is rotated away from the tabletop a first amount, the translation mechanism is fixed relative to the support element in a first position with the first element positioned in the receiver and the second element is not positioned in the receiver;
- wherein, in a second use configuration the support element is rotated away from the tabletop a second amount, the translation mechanism is fixed relative to the support element in a second position with the first element and the second element positioned in the receiver;
- wherein, in the first use configuration, the support element is rotated away from the tabletop a first angle of at least about seventy degrees;
- and
- wherein, in the second use configuration, the support element is rotated away from the tabletop a second angle of at least about eighty degrees.

A two-stage lock assembly configured to prevent structure collapse due to an insufficiently rotated leg assembly, 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 that includes an end on which a first element and a second element are disposed,
- 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 a 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;
- wherein, in the disengaged configuration, the leg is disposed between an angle of zero degrees to a first engagement angle of seventy degrees at which the first element is introduced to a receiver;
- wherein, in the first engaged configuration, the leg is disposed at or between the first engagement angle and a second engagement angle of ninety degrees;
- and
- wherein, in the second engaged configuration, the leg is disposed at the second engagement angle at which the second element enters 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 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 two-stage lock assembly including a disengaged configuration in which the translation mechanism is not fixed relative to the support element, a second engaged configuration in which the two-stage lock assembly fixes the translation mechanism relative to the support element, and a first engaged configuration in which the first element is positioned in a receiver in the support element and the second element is not positioned in the receiver;
- wherein, in the disengaged configuration, the leg is disposed between an angle of zero degrees to a first engagement angle of seventy degrees at which the first element is introduced to a receiver;
- wherein, in the first engaged configuration, the leg is disposed at or between the first engagement angle and a second engagement angle of ninety degrees;
- and
- wherein, in the second engaged configuration, the leg is disposed at the second engagement angle at which the second element enters the receiver.
