Locking enclosure, stiffening ring, and vertical mounting stiffeners for securing components

摘要

A latchable enclosure in the form of a box having a base, four sidewalls, and an open top face which may be closed by a cover plate or lid over its open top for covering components stored in the enclosure. The enclosure may be stiffened by providing a removable or permanent stiffening ring around the inside surface of the open top. This stiffening ring may also provide locations for attachment of components or mounting tracks. The enclosure may also include vertical mounting stiffeners that act to further increase the stiffness of the enclosure while also acting as mounting tracks for direct or indirect (through separate mounting brackets) attachment of components. The vertical mounting stiffeners may include a plurality of holes for said attachment.

主权项

1. An enclosure assembly for enclosing electrical components, comprising:
a body including a base and a plurality of sidewalls integrally formed with the base, wherein the plurality of sidewalls define an opening and extend from the base in a first direction perpendicular to the base; a cover; one or more mounting stiffeners coupled to the body in a spaced relationship from corners of the body and comprising a main shaft including a plurality of generally parallel apertures spaced along a length of the main shaft in the first direction configured to receive fasteners for mounting components thereon, a platform extending laterally outward from both sides of the main shaft in a second direction perpendicular to the first direction and including one or more platform apertures configured to receive a platform fastener, and a head including a head aperture configured to receive a head fastener; a unitary stiffening ring including a generally annular top portion having a planar extent with an inner and outer periphery, the inner periphery defining an opening that corresponds with the opening of the body, a first side, a second side, and a plurality of spaced holes extending through the top portion configured to accept the head fasteners to secure the stiffening ring to the head of the one or more mounting stiffeners through at least one of the plurality of spaced holes, wherein the stiffening ring is configured to be secured at least partially within the opening and at or near the opening to provide structural support when coupled to the body; and one or more latches coupled to at least one of the apertures of the one or more mounting stiffeners and adjacent to the cover, wherein the cover includes respective locking members movable to engage with the one or more latches for locking the cover to the body, and wherein the one or more mounting stiffeners are rigid, thereby providing structural support when coupled to the body.
