A table includes a table panel, first and second mounting members, and first and second leg assemblies. Each of the first and second mounting members is coupled or formed with the table panel. Each of the first and second leg assemblies includes a linking member having an end portion rotatably coupled with the first mounting member and another end portion rotatably coupled with the second mounting member. When the first or second leg assembly is unfolded, the linking member abuts one or more retainers of the table panel and forms interference fit with the first and second mounting members. This significantly reduces vibration when the table is in use.

A frame for sit-stand-tables comprising a longitudinal member (3), two height-adjustable legs (6, 7) with at least two telescopic profiles, namely an outer and an inner profile, and with a driving mechanism, driven by a motor unit (39), comprising an electric motor (46) and a gear. According to the invention the motor unit (39) is arranged in the longitudinal member (3) and connected to the driving mechanism in the height-adjustable legs (6, 7). Thus, a frame with a simplified construction is achieved. The construction of the legs (6, 7) can be simplified and at the same time the dimensions can be reduced, as it is not necessary to take the building-in of a motor into the legs into consideration. As both legs (6, 7) are driven by a joint motor unit (39), the electric control can also be simplified as it will not have to drive the two legs synchronously.

A foldable table includes a tabletop, first and second table leg assemblies, and first and second supporting assemblies. Each of the first and second table leg assemblies is pivotally coupled with the tabletop and rotatable with respect to the tabletop between a use position and a storage position. The first supporting assembly is pivotally coupled with the tabletop and first table leg assembly, and the second supporting assembly is pivotally coupled with the tabletop and second table leg assembly. Each of the first and second supporting assemblies includes first and second supporting members slidably and rotatably coupled with each other such that sliding and rotating movement between the first and second supporting members of a respective supporting assembly allows a corresponding table leg assembly to rotate with respect to the tabletop between the use and storage positions.

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.

A folding/unfolding mechanism includes first, second and third coupling pieces. Each of the first and second coupling pieces is configured to be fixed at an end of a bar and includes a hole and a slot with a closed bottom and an open top. The third coupling piece includes a slot with closed bottom and top. A first rod passes through the holes of the first and second coupling pieces and the slot of the third coupling piece. A second rod is integrally formed or coupled with a top portion of the third coupling piece, and movable together with the third coupling piece. The second rod is selectively inserted into the slots of the first and second coupling pieces, thereby selectively restricting the rotation of the first and second coupling pieces with respect to each other.

Disclosed are sliders, and frames and tables having sliders. A slider includes a sleeve, a pivoting portion and a controller. The sleeve is configured to slidably couple with a first bar, and a first hole and a pillar are formed at a first side wall of the sleeve. The pivoting portion is integrally formed or coupled with a second side wall of the sleeve, and configured to pivotally couple with a second bar. The controller is configured to control movement of the sleeve along the first bar. The controller includes a casing, a lever pivotally connected with the casing, a pin integrally formed or coupled with the lever, and an elastic member selectively pushing the pin into the first hole and a hole of the first bar, thereby restricting movement of the sleeve with respect to the first bar.
