A shelving system includes a plurality of horizontal support members, each horizontal support member having a length; a plurality of wall supports, each wall support including a first surface on which at least a portion of a horizontal support member rests; a plurality of brackets, each bracket attachable to the horizontal support members at different positions along the length of the horizontal support member; a plurality of vertical support members, each vertical support member coupled to at least one bracket; and a shelf attached to at least two of the plurality of vertical support members.

A shelf support for leveling a shelf of a laboratory climatic cabinet is provided. The shelf support includes a shelf support body configured to be secured to a wall of the laboratory climatic cabinet and to support the shelf and at least one shelf leveling mechanism associated with the shelf support body. When the shelf is supported by the shelf support, the at least one shelf leveling mechanism is configured to adjust a distance between the shelf and a floor of the laboratory climatic cabinet. A laboratory climatic cabinet is provided and includes a shelf support, which includes a shelf support body configured to support the shelf and a shelf leveling mechanism, secured to a first wall of the cabinet. When a shelf is supported by the shelf support, the shelf leveling mechanism is configured to adjust a distance between the shelf and a floor of the cabinet.

Provided are rack systems including at least one support rail configured with a plurality of axially extending bracket arresting slots and a plurality of corresponding locking locations, and at least one support bracket including at least two axially disposed engaging hooks readily detachably attachable with any two or more of the bracket arresting slots of the support rail, said support bracket further including a locking mechanism including a locking plunger configured for engaging with a locking location at the support rail.

An adjustable support rack includes a mounting base, a bracket and a support mount that are assembled to form a four-link mechanism, so that once the support mount is rotated, a lower supporting frame of the bracket is displaced, causing a bearing plate of the lower supporting frame to press against a pressure relief valve of a pneumatic cylinder of the bracket for allowing adjustment of the height of the support mount rapidly and smoothly.

A support frame includes a column, a rocker arm, a tray, an adjustment shaft and a fixing block. The column is vertically arranged, the rocker arm is horizontally arranged, and the column and the rocker arm are connected by a hinge. The rocker arm includes a transverse support tube connected to the hinge, and the adjustment shaft is arranged inside the transverse support tube. An elastic member has one end connected to the adjustment shaft and another end connected to the column or the hinge. The transverse support tube is provided with multiple U-shaped grooves, and the fixing block is arranged outside the transverse support tube, and the tray is connected to the fixing block. The fixing block passes through the U-shaped groove to be connected to the adjustment shaft; or, a screw passes through the U-shaped groove, to connect the fixing block to the adjustment shaft.

A suction-attached shelving system and method is provided. The system includes a suction-based attachment structure including a releasable suction disc, a suction housing, and a suction lever arm. The suction-based attachment structure may be attached to a vertical surface such as a window by using the suction lever arm to establish a suctional engagement of the releasable suction disc and suction housing with the vertical surface. The suction-based attachment structure is connected to a shelf structure by a shelf rotation axle. The shelf structure includes a front portion that may be folded relative to a back portion for ease of transport.

A shelving system is provided. The shelving system includes an upper rail, and optionally a lower rail, from which one or more upright supports extend. The upright supports are slidable within the upper and lower rails so that a user may vary their location. A shelf mounts to the upright supports. The shelf includes interlocking deck panels and selectively removable support bars so that it may be assembled onto the upright supports.
