Cantilevered retention systems for architectural systems are provided herein. As one example, a cantilevered retention system may include a support structure, a cantilever structure comprising a threaded channel and an L-shaped hook structure, and one or more retention sources configured to bias the cantilever structure to a first position, the cantilever structure being moveable between the first position and a second position via a fastener that traverses the support structure and at least partially traverses the cantilever structure and the one or more retention sources.

A reinforced server sliding rail mounting structure for connection to a server rack and to a server includes an inner sliding rail, a first ball bushing, an intermediate sliding rail, a second ball bushing and an outer sliding rail. A front bracket has an upper reinforcing rib and a lower reinforcing rib respectively located on upper and lower bracket walls thereof such that when the intermediate sliding rail is moved outward into the front bracket, the upper and lower reinforcing ribs are respectively engaged into respective outer ball grooves of the intermediate sliding rail and reinforce the structural strength of the intermediate sliding rail. The structure may further include top and bottom reinforcing components respectively located on respective rear ends of the upper and lower reinforcing ribs.

A sliding rail fixing structure in a server includes a sliding rail, a fastening plate with a fastening seat, and a clip. The fastening plate defines a restriction hole. The fastening seat includes a supporting member. The supporting member passes through the restriction hole to be positioned at a side of the fastening seat. A size of the supporting member matches a size of an installing hole defined on a pillar. The supporting member is positioned in the installing hole when the pillar is positioned at the side of the fastening seat. The clip can rotate on the fastening seat and includes a hook portion. The hook portion hooks onto the pillar to assemble the pillar to the sliding rail fixing structure. When the clip rotates through a preset angle, the hook portion moves away from the pillar to disassemble the pillar.

A hanging bracket for the wall assembly of a wall-cupboard includes, in combination: a metallic base, an arm assembled and articulated on the base and protruding from it with a hook configured for anchoring to a plate (or other equivalent element) fixed to the wall, first and second regulation mechanisms regulating the position of the arm in height and in depth, respectively, and a flange integral with the base and equipped with at least one fixing unit of the hanging bracket to the wall-cupboard, wherein the fixing unit includes a shear-resistant element cooperating with a fixing peg of the hanging bracket to a shoulder of the cupboard. According to the invention, the peg is fitted onto a collar protruding from the flange, there also being a reciprocal fixing element between the collar and the peg, to make them integral with each other.

A bracket assembly for attaching a shelf to a support structure at different angles. The bracket assembly comprises a bracket, an adjustment structure, and a locking structure. The bracket comprises a shelf support surface and a projecting portion with a notch extending from an attachment side of the bracket. The adjustment structure comprises a number of sides that are moveable between a plurality of different positions to change the shape of the notch in the projecting portion for attaching the bracket to the support structure at different angles. Different sides of the adjustment structure may be positioned to change the size of the notch for attaching the bracket to support structures with different thicknesses of material. The locking structure is configured to prevent movement of the adjustment structure when the adjustment structure is in position.

A latch assembly includes a latch body having a longitudinal wall portion extending from a front wall portion to a rear hinge portion, first and second latch members assembled with the longitudinal wall portion and laterally movable between an extended position and a retracted position, and a hinge bracket. The hinge bracket defines a mounting surface and is hingedly attached to the rear hinge portion of the latch body for angular adjustment of the latch body with respect to the mounting surface. When the latch body is oriented at a first angle, first and second mounting apertures in the front wall portion align with first and second mounting apertures in the hinge bracket, such that installation of mounting fasteners through the corresponding first and second mounting apertures of the front wall portion and the hinge bracket secures the latch body at the first angle.

An adjustable shelf riser includes a shelf and a pair of legs supporting the shelf. In one version, the legs include an upper portion removably attachable to the shelf and extending vertically below the shelf when the upper portion is attached to the shelf. The legs also include a lower extension portion removably attachable to the upper portion, the lower extension portion having a selectable connecting surface, the selectable connecting surface having a plurality of attachment locations for attaching the upper portion to the lower extension portion. The upper portion and the lower extension portion combine to define a height of the shelf above a horizontal surface on which the adjustable shelf riser is placed when the adjustable shelf riser is resting on the horizontal surface.
