Patent number: 6030063Abstract: A switchgear cabinet with a frame having frame members and corner connectors, and an open base closable by one or more bottom plates. A simple mounting of the bottom plates is achieved because the frame members serving as lower depth struts are covered from below by essentially U-shaped cover elements that have lateral arms and are connected to the depth struts and/or the corner connectors. The depth struts are chamfered in a region of their outer edges and form a seat for the outer lateral arms of the cover elements. The inner lateral arms of the cover elements have bearing flanges for the bottom plates folded toward the facing depth strut. U-shaped clamping elements with clamping screws can be used to join the bottom plates to the bearing flanges of the inner lateral arms of the cover elements.Type: GrantFiled: June 17, 1997Date of Patent: February 29, 2000Assignee: Rittal-Werk Rudolf Loh GmbH & Co.

Patent number: 5971511Abstract: A switchgear cabinet having a rack assembled from a plurality of frame legs bent at the side walls. The rack has open, vertical sides which are closed off by side walls and a rear wall fastened to facing frame legs of the rack. A cabinet door is hingedly connected to vertical frame legs of the rack front against which it is arrested in the closed position. The rear and side walls are covered by corresponding protective walls spaced apart from the rear and side walls and connected to facing vertical frame legs of the rack. The cabinet door is double-walled, an outer door wall of which is spaced apart from an inner door wall thereof and forms receptacle spaces for seals, hinges and locking elements free in the direction of vertical edges of the outer door wall. The protective walls of the side walls have beveled protective wall vertical edges which cover the free space between the protective wall of the rear wall and the receptacle space between the outer door wall and the rack.Type: GrantFiled: April 21, 1998Date of Patent: October 26, 1999Assignee: Rittal-Werk Rudolf Loh GmbH & Co.

Patent number: 5938461Abstract: A device adapter for pluggable connection to busbars of a busbar system with terminal connectors disposed in an oblong adapter housing and having catches for securing on a lower securing element and a section of a top hat rail for placing a device thereon. The adapter housing is divided into two halves in a longitudinal direction and parallel to an attachment direction. On their facing sides, the housing halves support securing elements distributed in the longitudinal direction over a separating plane, but offset in a step-like manner transversely thereto for securing, fixed against relative rotation, a plurality of U-shaped flat plug connectors, thereby enabling the pluggable connection. The housing halves are connected to each other and the U-shaped flat plug connectors are connected by conductors to terminal connectors housed in a contact block or directly to the device to be placed thereon.Type: GrantFiled: September 26, 1997Date of Patent: August 17, 1999Assignee: Rittal-Werk Rudolf Loh GmbH & Co.
