Disclosed are pivoting mechanisms, sliding mechanisms, frames and tables. A pivoting mechanism includes a first coupling piece, a second coupling piece and a rod. The first and second coupling pieces are pivotally coupled with each other. The rod is operated by gravity to automatically lock or unlock the first and second coupling pieces. A sliding mechanism generally includes a slider and a locking member. The slider includes a sleeve to be slidably coupled with a bar. The locking member includes a restriction piece, operated by an elastic piece to be disposed inside of the bar, to automatically lock the sleeve at a certain position of the bar.

A table has at least one table leg and a table top, the at least one table leg being pivotable relative to the table top, between an unfolded position and a folded position, about at least one first joint, wherein a strut is held on the table leg so that, at a first end, it is pivotable about a second joint, is provided for fixation of the table leg, and in the unfolded position of the table leg, it is operatively connected to the table top at a second end, opposite the first end. The table leg has a stop limiting the angle between the table leg and the table top in the unfolded position, such that the strut comes into frictional contact with the second end on a support surface held on the table top. In an unfolded direction of the strut, the support surface extends from a first end to a second end, and the distance from the first end of the support surface to the second joint in the unfolded position of the table leg is greater than the distance from the second end of the support surface to the second joint in the unfolded position of the table leg, so that, in the unfolded position, the strut is in self-locking frictional contact with the support surface.

A multi-position table includes a substructure for resting on a base, a superstructure pivotable between a first table position for use while sitting and a second table position for use while standing. The superstructure includes a first support associated with the first table position, the first support having a first top surface spaced a first distance from the base when the superstructure is in the first table position; a second support associated with the second table position, the second support having a second top surface spaced a second distance from the base when the superstructure is in the second table position, the second distance being different that the first distance. The table includes a locking member for locking a first and a second adjusting element together to prevent unintended movement from the first table position to the second table position or from the second table position to the first table position.

A variable height platform system comprises a frame assembly, at least two leg assemblies, a drive mechanism, and a sensor. The frame assembly is configured to support and be removably connected to a tabletop. The drive mechanism is configured to either extend or retract each leg assembly in a direction substantially perpendicular to the longitudinal axis to set a height of the frame assembly in an elevated position for use. The sensor is configured to sense position and movement of a user in a predetermined area including an area of the variable height platform system and an area proximate the variable height platform system. The controller is operatively connected to the sensor and drive mechanism. The controller is configured to operate the drive mechanism in response to the sensor sensing the position and movement of the user in the predetermined area.

Disclosed are pivoting mechanisms, sliding mechanisms, frames and tables. A pivoting mechanism includes a first coupling piece, a second coupling piece and a rod. The first and second coupling pieces are pivotally coupled with each other. The rod is operated by gravity to automatically lock or unlock the first and second coupling pieces. A sliding mechanism generally includes a slider and a locking member. The slider includes a sleeve to be slidably coupled with a bar. The locking member includes a restriction piece, operated by an elastic piece to be disposed inside of the bar, to automatically lock the sleeve at a certain position of the bar.

A folding table includes a support stand, a fold mechanism, and a table top. The support stand includes a top seat having a first engaging portion. The fold mechanism includes a fold seat pivoted to the top seat, a resilient unit, and an operating member having a second engaging portion. When the table top is at an unfolded position, the operating member is operable from a lock state, where the second engaging portion of the operating member is biased by the resilient unit to engage the first engaging portion of the top seat, to an unlock state, where the second engaging portion is disengaged from the first engaging portion against a resilient force of the resilient unit, thereby permitting pivot movement of the table top to the folded position.

A foldable table includes a table tops and legs mounted for movement relative to the table top.

A combination chair and desk apparatus includes a frame, a stationary member connected to the frame, a pivot member that is pivotable with respect to the stationary member between a chair position and a table position, and a latching device that latches the pivot member to the stationary member in the chair position and alternately in the table position. The pivot member includes a chair surface and a table surface that is transverse to the chair surface. When the pivot member is in the chair position, the chair surface is oriented for supporting a user, and when the pivot member is in the table position, the table surface is oriented for supporting an object.

A table that can be divided into separate sections, each section capable of being hung on a wall as a picture frame. When the sections are combined a table is defined that can be folded along a partition. The table further includes retractable, telescopic legs. A plurality of clamp members are used to hold a backing member in place, which provides support for a graphic mounted within the table top assembly.

A table may include a tabletop, a frame, and a leg assembly. The leg assembly may include a support element, a translation mechanism, and a lock device. The support element may include an end structure attached to an elongated structure. The end structure may be rotatably coupled to the frame such that the support element is rotatable relative to the frame between a first position and a second position. The translation mechanism may be retained relative to the support element and the frame. The translation mechanism may be configured to translate along the support element as the support element rotates. The lock device may be configurable in an engaged arrangement in which the lock device fixes the translation mechanism to the support element and in a disengaged arrangement in which the translation mechanism is not fixed relative to the support element.
