A folding shelf may include a first shelving unit having first side frames, one or more shelving boards, a first retractable control unit; and a second shelving unit having second side frames, one or more second shelving boards, a second retractable control unit. The first/second retractable control unit may include a first/second main body; a first/second pole partially received in the first main body; and a first/second locking member. When the folding shelf is folded, the user can first twist a first/second locking element to untightened first/second main body and first/second pole. The user can then lift the side frames in the center portion as to collapse the shelf. More specifically, the sliding movement of the first pole and the second pole can bring two side frames toward the center portion of the folding shelf to significantly minimize the size thereof.

A display unit including a plurality of shelves and at least one collapsible support element, wherein the display unit is configured to be moveable between a compact state in which the at least one support element is in a collapsed position, and at least one assembled state in which the plurality of shelves are assembled whereby each assembled shelf is separated by, and supported by the at least one support element in an extended position.

An angle bar includes two longitudinal angled plate portions, and a corner portion connecting therebetween. The corner portion has an inner corner surface bounding an inner corner space and an outer corner surface. A stopper protrudes into the indented corner space, and has an abutment face extending across the indented corner space. A limiter protrudes into the indented corner space from the inner corner surface, and has a through hole opening in a direction along a bending line of the corner portion. A modular post assembly has at least two angle bars abutting each other, and a fixing rod extending through the through holes of the bars along the bending line and limited between the stoppers for fixing together the bars.

Various embodiments of the present disclosure provide a storage, shipping, and display unit that can be loaded with product, shipped after loading, and used as a display unit after shipment.

Electrical and electronic devices are often installed in so-called racks. Racks of this type are shelf-like frames into which the devices are inserted and can be fastened, for example by means of screws. The racks commonly provide a pair of support rails for each device, upon which rails the device can be placed and can be inserted into the rack. The device can be subsequently fixed to the rack, for example screwed in. Within the scope of the invention, a device arrangement (1) is disclosed comprising at least one stacking device (4), wherein the stacking device (4) has adjustable feet (15) on the bottom surface (11) for supporting on a placement surface, comprising a base device (3), wherein the at least one stacking device (4) is arranged on the base device (3) so that these form a device tower (13), wherein the adjustment feet (15) of the stacking device (4) stand on the base device (3), wherein the device arrangement (1) comprises a 19-inch frame (2) and the stacking device (4) and the base device (3) are designed as insert devices with front plates (6) for the 19-inch frame (2), wherein the base device (3) and the at least one stacking device (4) are arranged as a device tower (13) in the 19-inch frame (2), and wherein the front plates (6) are connected to the 19-inch frame (2).

A middle shelf installation tool is disclosed for use in combination with a pair of upstanding corner posts during the assembly of a boltless shelving system. Upper and lower sets of hingedly connected corner post surrounding members are spaced one above the other so as to extend across the top and bottom of the installation tool. The installation tool is wrapped in surrounding engagement around the bottom of an upper one of the pair of corner posts and the top of the lower one of the pair. The installation tool forms a splice to hold the upper and lower corner posts in axial alignment one above the other to facilitate the location by a single individual of a middle shelf at the intersection between the corner posts to lie between upper and lower shelves of the system. Once the middle shelf has been installed, the installation tool is pulled off and removed from the corner posts.

Various embodiments of the present disclosure provide a storage, shipping, and display unit that can be loaded with product, shipped after loading, and used as a display unit after shipment.

The invention relates to a display, a kit, and a method for displaying goods. The display has a compact and one or more built-up configurations. The display has shelves that can be supported by hingedly connected, slideably attached, and telescopic side walls. The kit has a display and an advertisement wall for the display. The method relates to the spacing of two shelves by means of two side walls by exerting a force on one of both shelves and hinging and sliding the side walls to a position in essence perpendicular to both shelves.

A cage for housing laboratory animals, said cage includes a bowl and a cap or cover which may be positioned on said bowl in a removable manner, wherein the cap and the bowl, with the cap positioned on the bowl, define an internal space which is closed and not accessible from the outside, wherein in the internal space a feeder is positioned, adapted to contain food adapted to feed the laboratory animals, wherein the cage is equipped with first means adapted to detect the presence and/or quantity of food in the feeder.

A hang harvesting system includes a plurality of stackable pods each including a platform, and a plurality of support shafts extending vertically from the platform. Each of the support shafts defines a plurality of notches configured for suspending a horizontal bar from the support shafts. Top ends of the support shafts of one pod are configured to support a platform of another pod thereon.
