A mounting assembly includes a base; a post extending from the base, the post defining a vertical axis; a beam mounted on the post and being pivotable about the vertical axis, the beam comprising a first portion extending in a first horizontal direction and terminating in a first end, and a second portion extending in a second horizontal direction opposite of the first direction and terminating in a second end; an equipment mounting bracket at the first end; a latch along the beam and having an engaged position and release position, wherein in the engaged position the latch prevents the beam from pivoting; and a latch release along the second portion of the beam. A method of accessing equipment mounted on the mounting assembly includes actuating the latch release such that the latch moves from the engaged position to the release position; and rotating the beam about the vertical axis.

Disclosed is an automatic released foldable door having a two-way door structure, which foldable door comprises a first closing door device (11) and a second closing door device (13), wherein a first door leaf (2) is connected to one side of the first closing door device (11), the second closing door device has one side connected to the first door leaf (2) and the other side thereof connected to a second door leaf (6), the second door leaf (6) is a door-in-door and a two-way door structure; and the foldable door further comprises a plurality of fixing devices (3, 31, 7) and at least one hinge (4). The foldable door has a relatively small turning radius and can be folded for receiving, and the door-in-door can be rotated in different directions.

The invention relates to a door closer mechanism having a receptacle, countersunk in the door frame, for the deadbolt of a device, countersunk in the door, for controlling the deadbolt from the closing position to the opening position by means of a manually controllable actuation member. So that, without an additional key-actuated lock, the closing position can be locked in the closing position and fixed without making the ease of adjustment into the opening position more difficult, the invention provides that the actuation member of the device countersunk in the door is embodied as a handle recess, which in the closing position controls a slide via a rotatably supported angled control piece, and the slide, via a rotatably supported lever, secures the deadbolt in the receptacle in the door frame, and upon actuation of the recessed handle in the door, via the angled control piece and the slide, the deadbolt can be adjusted into the opening position of the door, and the door is enabled to open.

A lever-operated latch device includes an assembly of a case body, an actuation body mounted on the case body, a linking member and a slide body. The actuation body has a free end and a pivoted end pivotally connected with the case body in cooperation with elastic members. The free end of the actuation body is formed with two protruding arms and an opening section positioned between the protruding arms. An operation section is disposed in the opening section. The linking member has a first end pivotally connected with the free end of the actuation body (or the operation section) and a second end connected with the slide body. When an operator presses the operation section, the actuation body is permitted to move from a closed position to an opened position so as to drive the linking member and the slide body to move.

A toggle latch device translates a first push and release of a button to a locking pin translation from retracted to extended from within a housing. A second push and release of the button reverses the locking pin translation from extended to retracted back within the housing. The latch button remains desirably flush with the housing after each push and release. The translation of the latch button and that of the locking pin is angularly displaced by 90 degrees allowing the toggle latch device to employ a unique lever system which includes a buckling spring combined with a reversing hat which forces the locking pin in each of extension and retraction.

A latch having a support bracket having a guide slot formed in a bottom surface. A linkage at least partially received within the guide slot and a handle coupled to the linkage transitionable between an open position and a closed position. A pin releasably coupled to the linkage such that when the handle is in the closed position the pin is coupled to the linkage and in the open position the pin is removable from the linkage. As the handle transitions from the open position to the closed position, the linkage moves within the guide slot.
