Abstract: A spring hinge construction for an overlay door for a metal cabinet or other enclosure where the hinge provides the door with a positive closed position and a positive holding 90* open position, with the hinge having a toggle with an overcenter position for both the 90* open and the closed positions. The hinge includes an L-shaped cabinet wing and a channel-shaped door wing joined at a pivotal axis, an elongated toggle having one end adapted to project through a wall of the door wing during opening or closing movement and an enlarged opposite end engaging the cabinet wing adjacent the pivot axis. A compression spring encompasses the toggle with one end engaging the enlarged end of the toggle and the opposite end abutting the above-mentioned wall of the door wing.

Abstract: An extruded thread-cutting nut for the forming of threads on an unthreaded post or stud which is a one-piece nut having an extruded body provided with internal threads therein, a body flange integral with and positioned at one end of the extruded body, and a face flange parallel to and joined to the body flange by a short sidewall. The face flange is provided with a central aperture aligned with the nut body and incorporates therein a helical thread provided with one or more cutting edges. An unthreaded stud first engages the cutting edge and thread in the face flange to form the thread and then engages the interior threads of the nut body.

Abstract: An improved spring latch is made of three components including a housing and a pawl serving as a latch which is adapted to nest within the housing. A single coil spring is positioned between a portion of the housing and a pocket formed in the pawl to pivot the pawl into a latching position. Tabs preformed in the housing serve as the pivot axis for the pawl. Portions of the pawl and the housing cooperatively engage to limit the rotational or pivotal travel of the pawl relative to the housing.
