A male pin attaches on lateral edges of shelves and respective female housings on lateral walls of display stands after gluing the shelves and lateral walls. The male pin and its coupling end have hinged rear flaps securable to each other by coupling pegs and recesses, and with coupling lugs and cradles. The female housing has a front track that incorporates a rear clip. The male pin and female housing are secured, respectively, in indentations near ends of front shelf edges and in indentations in lateral walls. For assembly, the pegs/recesses and lug/cradle of the male pin insert in the indentation, for securing by quick engagement at both ends of the front edge of the shelf and laterally exposing the coupling end. The female housing inserts by its rear clip in the lateral wall indentation, positioning the front track thereof to receive the coupling end of the male pin.

A fixing device for a safety screen includes a bracket, a support member and a locking member. The support member includes a plurality of openings, and two of the openings include keyhole slots that are spaced from one another along the support member. Each of the keyhole slots include an enlarged portion and a slot. The bracket includes at least one engagement member that has a shank portion and a head. The head is receivable through the enlarged portion thereof. The shank portion is receivable by the slot of any of the keyhole slots, and the locking member is attached to the bracket. The bracket is engageable with the support member by inserting the head through the enlarged portion. The locking member is engageable with the support member following translational movement of the engagement member along the slot, the locking member thereby locking the engagement member against translational movement.

An example apparatus includes a bracket having a rack attachment member and a guard attachment member, and upper and lower engagement tabs that are coupled to the rack attachment member and have a stem portion and a head portion. The rack attachment member has a lock pin hole above the lower rack engagement tab. The lock pin hole is sized and positioned to provide sufficient cross-sectional area within a rack engagement distance to allow passage of a bracket lock pin therethrough within the rack engagement distance. The apparatus further includes a bracket lock pin having a stabilizing leg coupled to a lock pin head, where the stabilizing leg fits through the lock pin hole and the lock pin head does not. The stabilizing leg urges the lock pin head toward the lock pin hole when the stabilizing leg is passed through the lock pin hole.

A nested vertical shelf mount system includes vertical bars having a first set of vertically spaced apart mounting features and a second set of vertically spaced apart mounting features spaced inside and behind the first set of vertically spaced apart mounting features. The mounting features may be any feature allowing a shelf, panel, or the like, to be attached to the vertical bars. A panel may be attached to the second set of vertically spaced apart mounting features and a shelf may be attached to the first set of vertically spaced apart mounting features residing over the panel to provide a finished appearance.

The locking member is engageable with the support member following translational movement of the engagement member along the slot, the locking member thereby locking the engagement member against translational movement.

A shelf device includes a plurality of support units and a plurality of shelf units. Each of the support units includes a plurality of mounting holes. Each of the shelf units includes a plurality of insertion units, and a plurality of positioning members that are cooperatively mounted to the support units. Each of the insertion units includes at least one insertion member inserted into a corresponding one of the mounting holes. Each of the positioning members is sleeved on a neck portion of the insertion member of a respective one of the insertion units, and abuts against a head portions of the insertion member of the respective one of the insertion units and one of the support units to prevent the head portion of the insertion member from passing through the corresponding one of the mounting holes.

Storage and grow rack systems include splice joints for stacking and joining upright posts, structural support beams with integral drainage, and studs or rivets providing releasable attachment of cross members to upright posts.

A disinfection or sterilization cabinet includes a cabinet frame defining an interior space, a door coupled to the cabinet frame, and an internal cabinet framework coupled to the cabinet frame and disposed within the interior space. The door is movable between a first position that substantially prevents access to the interior space and a second position that enables access to the interior space. The internal cabinet framework includes at least one bracket coupling structure. At least one bracket is removably coupled to the internal cabinet framework via the at least one bracket coupling structure. The at least one bracket includes a low contact object configured to reduce a contact area of an object supported by the at least one bracket and the at least one bracket. The cabinet includes a disinfectant or sterilization element configured to at least partially disinfect or sterilize the object.
