  • Patent number: 11920392
    Abstract: A hinge assembly includes first and second hinge units and an electrically conductive pin. The first hinge unit is mounted to a frame structure of an enclosure and includes a pin support comprising a barrel, a knuckle, or both, a pin receptacle arranged in the pin support, and an electrically conductive structure disposed at least partly inside the pin support and adjacent the pin receptacle. The pin rotates in the pin receptacle. The second hinge unit is carried on the pin and is door mounted. The second hinge unit and door can be removed from the first. The electrically conductive structure is biased against the pin and remains in contact while the pin rotates, and is electrically connected to the enclosure when the first hinge unit is mounted to it such that the pin is electrically bonded to the enclosure while the pin rotates.

  • Patent number: 11678456
    Abstract: A hardware assembly for installation in a slide-type mounting rail of an electronic equipment enclosure includes a spring retainer and a hardware component received at least partially within the spring retainer. The spring retainer has a rear wall and a deflectable spring arm extending in a forward direction from each end of the rear wall. Each spring arm includes a distal end that extends inward toward the distal end of the other spring arm. The hardware component includes a generally oblong head and a plurality of cam bosses arranged at a front-facing side thereof. Each spring arm engages and is partially deflected outward by a respective one of the cam bosses, thereby clamping the hardware component within the spring retainer.

  • Patent number: 11678458
    Abstract: A method of securing a structure against a slide-type mounting rail of an electronic equipment enclosure includes: providing a hardware assembly having a spring retainer and bolt, a head of which is received at least partially within the spring retainer; positioning the hardware assembly within a T-slot channel of the slide-type mounting rail such that bent edges of deflectable spring arms engage ledges of the T-slot channel to prevent the retainer from rotation; configuring the bolt from an unlocked position to a locked position by rotating the bolt a quarter turn relative to the retainer to position the head transversely within the channel, thereby obstructing the hardware assembly from inadvertent removal from the slide-type mounting rail; placing the structure against the slide-type mounting rail such that a shaft extends through an aperture; and tightening a nut onto the shaft such that the nut is pressed firmly against the structure.
