A foldable supporting frame includes an upper frame and a plurality of legs disposed below the upper frame when unfolded to support the upper frame. The upper frame includes a plurality of bars, with adjacent bars in the plurality of bars coupled to each other or integrally formed with each other at their adjacent end portions. Each of the plurality of legs is coupled with a corresponding bar in the plurality of bars and independently rotatable about an axis defined by the corresponding bar. When folded, the plurality of legs is disposed in an interior defined by the upper frame.

A worktop (1) comprising a leaf (3) hingedly coupled to a wall (6) about a hinge axis (7) by a pair of support mechanisms (91) between a usable state and a folded state. Each support mechanism (91) comprises a first mounting member (93) and a second mounting member (92) which are pivotally connected by a main pivot pin (94) which defines the hinge axis (7). A strut (15) extends between the first and second mounting members (93,92). A first pivot pin (19) at a first end (17) of the strut (15) is slideable and pivotal in an elongated first guide track (96) in the first mounting member (93) between first and second positions (73,74). A second pivot pin (20) at a second end (18) of the strut (15) is pivotal in a slideable element (25), which in turn is slideable in a second guide track (14) of the second mounting member (92) between first and second positions (26,27). A plunger (40) in the slideable element (25) engages a receiving opening (43) in the second guide track (14) for retaining the slideable element (25) in the first position (23) for retaining the leaf (3) in the usable state. On disengagement of the plunger (40) from the recess opening (43), the leaf (3) is pivoted downwardly in the direction of the arrow (A) from the usable state to the folded state, and the slideable element (25) slides to a second position (24) in the second guide track (14) while the first pivot pin (19) slides from the first position (73) to the second position (74) in the first guide track (96).

Disclosed are adjustment mechanisms and structures including one or more adjustment mechanisms. An adjustment mechanism comprising a casing, first and second arms, a second arm, a button, and an elastic member. The first and second arms are movably disposed in a channel of the casing. The button is operably coupled with the first and second arms and selectively pushes a first end of the first arm out of a first side of the casing and a second end of a second arm out of a second side of the casing. The elastic member abuts the casing and button such that the button is held at a desired position and consequently the first and second arms are held at a desired state under normal conditions. The adjustment mechanisms of the present disclosure provide an easy, convenient and safe means for height or length adjustment.

A folding table with increased seating space is provided. The table may include a tabletop and a plurality of legs affixed to an underside of the tabletop. The legs may be configured to be movable, bi-directionally, between an unfolded position and a folded position. The folding table may include two or more folding mechanisms for moving the legs between the unfolded position and the folded position. The folding table may include a plurality of bump brackets affixed to the underside of the tabletop. Each bump bracket may correspond to one of the plurality of legs. When the legs are in the unfolded position, each bump bracket may be configured to engage the corresponding leg and provide structural support for the corresponding leg.

A foldable frame with enhanced stability includes a mounting assembly, a first leg assembly and a second leg assembly. Each of the first and second leg assemblies are pivotally coupled with the mounting assembly and rotatable with respect to the mounting assembly between a use position and a storage position. Each of the first and second leg assemblies includes a substantially straight first leg and a substantially straight second leg. The first and second legs are slanted outwardly to increase the supporting area and thus enhance the stability of the foldable frame and stability of other structures supported by the foldable frame.

A travel case having features that allow the travel case to stand on four legs to form a horizontal surface suitable for use as a work table is disclosed. The travel case is adapted to operate in two modes including a default mode, and a props/table mode. In the default mode, the travel case is configured to function as a conventional travel case. In the props/table mode, the travel case is configured to stand on four legs, thereby allowing a case body to be used as an elevated horizontal support surface. The props/table mode is configured to facilitate ease of unpacking and packing of the travel case. The travel case comprises a flip switch to activate one of the default mode or props/table mode.
