An expandable and contractable storage device comprised of a frame, X-bars, a leveler, a movable bar, rolling wheels and attachment guides. The frame includes at least one elongated support element having a support ledge. The leveler is connected to the moveable bar and a grooved shaft. The rolling wheels are attached to carriages and the movable bar are located inside elongated U-shaped channels and channels of the attachment guides. The X-bars are attached to the carriages and the attachment guides. Stoppers are movably located inside the elongated U-shaped channels and the channels of the attachment guides. The rotation of the leveler will rotate the grooved shaft and move the movable bar in a forward direction forcing the rolling wheels to rotate and translate forward along the channels and the X-bars will move in an upward or downward direction and the frame moves in a downward or upward direction.

A product displaying holder system is configured to be removably coupled to a surface of a component. The product displaying holder system includes a retaining bracket having a longitudinal main beam and one or more securing mounts. Holder channels are formed through the longitudinal main beam. One or more product holders are removably coupled to the retaining bracket. Each product holder includes a bracket-mating stud that is retained within one of holder channels. The holder channels allow the product holder(s) to be selectively positioned at different locations along the main beam. One or more securing assemblies are coupled to the securing mount(s). The securing assemblies are configured to securely couple the product displaying holder system to the surface of the component. In at least one embodiment, the securing mount(s) are perpendicular to the main beam.

A Self-Standing Merchandise Frame is provided for displaying merchandise items on a store and allowing the attachment of multiple racks of numerous sizes, for instance, 24 inches, 48 inches and 96 inches. The embodiment is configured of a sign plate, a first and a second vertical tubes, an upper and a lower support and a base plate which structurally support the self-standing of the frame. Depend on the particular application, Self-Standing Merchandise Frame could be assembled as a single stand or a double stand, without any limitation and restriction.

A combinative shelving unit includes two stand assemblies and a load tray. The two stand assemblies are arranged parallel to each other. Each stand assembly includes a pair of posts and a transverse link connected between the pair of posts. Each transverse link has a first assembling portion and a second assembling portion. One side of the load tray has a connecting portion and another side thereof has a second connecting portion. The first connecting portion and the second connecting portion are staggered in position. The first connecting portion engages with the first assembling portion of one of the transverse links, and the second connecting portion engages with the second assembling portion of another one of the transverse links.

This present disclosure is about an electric shelf which has at least one column to be installed on a wall, a slidable component arranged on the column to slide along the column vertically, at least one layer of shelf board component connected to the slidable component to move simultaneously with the slidable component, and a linear driving device connected to the slidable component and the column to actuate the slidable component to move relative to the column. Advantages of the present disclosure compared to prior arts include a simpler structure and less space occupied by the shelf board component.

The present disclosure provides lockable cover assemblies that can cover mounting fasteners used to secure network devices to mounting structures, including racks, rack-mounted enclosures, cabinets or other mounting enclosures used to mount network devices, or utility boxes used to mount network devices. The lockable cover assemblies can be configured to cover the mounting fasteners of one or more network devices or the lockable cover assemblies can be built into a mounting enclosure and lock each network device in the rack.

A utility storage system is provided, the system comprising a plurality of flat panels, the panels disposed atop one another. The system also comprises a plurality of vertically disposed support devices to provide support for panels disposed above. The system also comprises connectors disposed at corners of upward facing surfaces of the panels, the connectors providing seating for bases of the support devices. The supports are extensible and retractable. The panels comprise shelves that are positioned in one of a level manner and an angled manner. The shelves are disposed at one of uniform and non-uniform vertical distances from one another. The vertical distances are adjustable via one of extension and retraction of the support devices. Extension and retraction are effected via use of a telescoping feature of the support devices. Each support device contains a locking mechanism for securing height of associated support device.
