Abstract: In one aspect of the present disclosure, a rack system includes a pair of arm assemblies that include an arm with reversible brackets on either end of each arm. The arm assemblies attach to the rack rails and support a component such as a server. The brackets are formed to selectively rotate with respect to the arm between a first position and a second position. In the first position the brackets are operable to interface a rack system rails that have a first interface type. In the second position the brackets are operable to interface rack system rails that have a second interface type. This allows the arm assembly to be installed in different types of rack systems.

Abstract: An assembly and associated installation method for a server or other electronic equipment enclosure installable into a rack solves both the issues of a single person installation method, as well as tolerance stack-up problems. A mounting bracket is attached to each end of a sliding rail coupled to the server or other equipment enclosure. The mounting bracket includes pins which are inserted into mounting apertures in the posts of the rack to temporarily retain and hold the sliding rail in the rack. Subsequently, a single user can then insert screws or other mechanical fasteners to securely attach the mounting bracket and sliding rail coupled thereto to the rack. Advantageously, the mounting bracket is fixedly secured to the rack and the sliding rail is permitted to move, translate or pivot relative to the mounting bracket to account for tolerance stack-up issues or other abnormalities in the dimensional fit between the server and rack system.

Abstract: An angle bar rack formed of horizontal bars and vertical angle bars, the horizontal bars having hook holes and recessed retaining holes respectively disposed at the inner sidewall of each horizontal bar adjacent to the hook holes, the vertical angle bars having upward hooks respectively hooked in the hook holes of the horizontal bars, each upward hook having a retaining portion curved outwards and respectively engaged into the recessed retaining holes of the horizontal bars.

Abstract: A beam and tension rod arrangement is for use with a push back storage rack system. A front beam extends between two front vertical uprights across the loading position of one or more cart lanes. An interior structural cross support extends between two interior vertical uprights that are located at points along the length of each cart lane. Diagonal tension rods extend from each end of the interior structural cross support to points on the front beam's structural angles that are adjacent the middle portion of the front beam. When a loaded cart collides with the front beam, the majority of the collision forces are directed toward the middle portion of the front beam, which exerts diagonal tension forces on the tension rods between the front beam and the interior structural cross support. The diagonal tension rods serve to brace the front beam against flexing, transferring much of the impact strain to the interior structural cross support.

Abstract: A storage rack has a spaced apart upright frames or vertical columns. Load beams extend between the upright frames. The load beams have flattened or flared ends, allowing the load beams to be directly bolted onto the vertical upright frames.

Abstract: A metal deck is received on the front and rear beams of a conventional rack system and is specially configured to receive a conventional nine leg plastic pallet. Weight and cost efficiency in the deck is achieved by concentrating the deck mass in those segments of the deck which make contact with the legs of the plastic pallet, and more particularly by recognizing that the center row of pallet legs carries a greater fraction of the pallet load then each of the outside rows of pallet legs. Closely spaced parallel front to back wire sections define pallet leg row support segments for the three rows of posts or legs of a plastic pallet, distributing the load of each leg over multiple wire segments. Front to back wires with an upwardly opening v-section are connected by struts to the wires within each support segment. Thus a single truss is formed as a part of each side support segment, and two trusses are formed as a part of the center support segment.
