A system for mounting to an underside of a work surface of an office furniture structure includes a storage structure and a bracket. The storage structure includes at least one storage chamber and at least one installation feature coupled to the at least one storage chamber. The bracket includes at least one securing feature configured to secure the bracket to the underside of the work surface of the office furniture structure. The bracket further includes at least one installation feature configured to couple the least one installation features of the storage structure. At least one of the storage structure and the bracket includes at least one restraining feature configured to engage the other of the storage structure and the bracket and inhibit the storage structure from being detached from the bracket.

A folding shelf includes a first sheet body and a second sheet body. The first sheet body has a first block, a second block, a third block, a fourth block, a fifth block and a sixth block. The first block is in a trapezoidal shape and the second block is in a trapezoidal shape and its upper bottom edge is connected to an upper bottom edge of the first block to define an engaged status. The third block is in a triangular shape and connected to one of the side edges of the first block, and the fourth block is in a triangular shape and connected to the other side edge of the first block and configured to be symmetrical to the second block. The fifth block is in a trapezoidal shape and its side edge is connected to one of the side edges of the second block, and the sixth block is in a trapezoidal shape and its side edge is connected to the other side edge of the second block and configured to be symmetrical to the fifth block. The arrangement of the first to sixth blocks allows the first sheet body to from a contour line of a rectangular sheet structure. The edges of the first to sixth blocks can be folded into a shelf. The second sheet body has an area smaller than the first sheet body, and a side of the first sheet body is partially disconnected from the first sheet body. Therefore, users can form the shelf by folding to facilitate the application of placing objects. When the shelf is not in use, the shelf can be maintained as a sheet body to facilitate storage and carrying.

An elevation working platform includes a lower support and an upper support. At least one group of X-type elevation mechanisms is provided between the lower support and the upper support. The elevation working platform further includes an elastic element. A first end of the elastic element is connected between two end points of a first support rod or a second support rod. A second end of the elastic element is connected to the lower support or a second hinging seat capable of sliding relative to the lower support. Using the X-type elevation mechanisms, the front and back positions of the upper support do not change in an elevating process of the upper support, the structure is simple and practical, and the cost is relatively low.

A tablet electronic product supporting frame includes an encapsulation box. The encapsulation box is rotatably coupled, at a front side thereof, with a carriage base. The carriage base has four fastening members to respectively couple with an upper clamp member, a lower clamp member, a left clamp member, and a right clamp member, so that the upper clamp member, the lower clamp member, the left clamp member, and the right clamp member are rotatably mounted to the carriage base and are allowed to adjust of the positions thereof for clamping. The carriage base is provided, on a front surface thereof, with a backing plate that is mounted thereto by an adjustment screw rod. As such, a supporting frame that is fit to carry and support tablet electronic products of various sizes and helps improve stability and burglary protection is provided.

A storage device coupleable to a structure includes a mounting plate and an external plate coupled to the mounting plate to define a receiving cavity. The storage device also includes a hinge plate received in the receiving cavity and coupled to the external plate, with the hinge plate pivotably moveable about a pivot axis between an open position and a closed position.

An adjustable supporting frame is disclosed for supporting a display. The adjustable supporting frame mainly comprises a base, a upright, a tilting unit, and a rotating unit, wherein the tilting unit pivotally rotates around an axial line of a connecting shaft, and the rotating unit rotates around a virtual axis, the axial line and the virtual axis intersect with each other.

A stand includes a base that is attached to a housing of an electronic device and extends between a mounting surface and the housing; and a shelf including a first wall facing the mounting surface, and a second wall extending from the first wall in a first direction crossing the first wall. The shelf is to be movably supported by the base between a first position and a second position. The first position is a position in which the first wall is accommodated in the base and the second wall is adjacent to the housing. The second position is a position in which the first wall protrudes from the first position in a second direction crossing the first direction and the second wall is spaced apart from the housing.
