A plastic arrangement that includes a first plastic component, a second plastic component, and a plastic lock mechanism for fastening the second plastic component to the first plastic component. The plastic lock mechanism includes a first lock unit and a second lock unit. The first lock unit includes a U-shaped cantilever member, a catch element and a catch element retention part. The second lock unit includes a protruding member and a protruding member retention part. The plastic lock mechanism provides a locked position wherein the catch element retention part restricts movement of the catch element for preventing the second plastic component from separating from the first plastic component, and the protruding member retention part restricts movement of the protruding member for hindering the moving of the first lock unit to a released position.

There is disclosed a dead-latching slam bolt lock that includes a rotating dead-latching slam bolt which prevents attempts at breaking in without actuating the lock mechanism. A tongue or toggle acted on by the door jamb engages the bolt and initiates rotation thereof in the door closing direction, but is passive in the opening direction. The locking mechanism may be manual or electronic, and controls the position of a blocking element which alternately prevents and permits unlocking (rotation) of the rotating bolt. In a forward or blocking position, the blocking element prevents rotation of the bolt from a locked position, while in a retracted position the blocking element permits rotation of the bolt to an unlocked position. A spring detent plunger holds the rotating bolt in either its locked or unlocked positions.

The present gate handle includes a push button that is pushed before the gate handle is slid from a closed position to an open position on top of a support member. The support member includes a resilient button that extends into the gate handle and is pushable out of the gate handle by the push button. The support member further includes side slots that are engaged by side slides extending from the handle.

A rotatable window lock including a cam positioned within a housing and rotatably connected to a handle. The housing defines a vertical protrusion on the exterior surface sized and configured to be inserted within an aperture defined in the bottom surface of the handle. By positioning the protrusion closer to the housing edge than the housing center, the protrusion is able to rotatably refrain the handle, preventing inadvertent rotation of the handle and unauthorized window access.

A latch assembly for housing cover is provided. Latch assembly has switch, latch, elastic clamp, and pushbutton. Switch is disposed on first side of cover. Switch is slidable in first direction to unlocked position for unlocking latch assembly and slidable in second direction to locked position for locking latch assembly. Latch has projection for engaging and disengaging with latch slot in housing for releasably latching cover to housing. Elastic clamp has detent portion for releasable engagement with notch in second side of cover. Latch and elastic clamp are disposed on second side of cover opposite switch and coupled to switch. Pushbutton extends through aligned openings in switch, latch, and portion of elastic clamp. Latch assembly is unlocked by depressing pushbutton to impinge on elastic clamp portion, thereby disengaging detent portion from notch and by simultaneously moving the switch in the first direction.

A tamper-proof lock includes: a housing, shaft/handle, cam, lever, spring, and plate. The shaft is pivotally mounted in a housing orifice, with the cam pivotally mounted to the shaft. The cam has first and second shaped openings at first and second respective radial positions, and an arcuate recess. The lever is secured to the shaft, and has a protrusion that alternately engages each of first and second ends of the arcuate recess to respectively/selectively drive the cam to rotate/counter-rotate in first and second directions, into locked and unlocked cam positions. The spring biases the plate for a protrusion thereon to be respectively received within each of first and second shaped cam openings, when aligned therewith at those cam positions, and for a curved surface of the plate to be correspondingly received within first and second curved cam recesses, respectively, when aligned therewith, which facilitate withdrawal of the plate protrusion.

A camera housing comprises a four-sided frame. A first side of the four-sided frame includes a first segment, a second segment, and a latch mechanism with a first latch component and a second latch component. The first latch component and the second latch component are pivotally coupled such that in a closed position, the frame securely encloses a camera and in an open position, the first segment and the second segment are separable.

A camera housing includes a frame having sides configured to secure a camera along an outer perimeter of the camera, one of the sides of the frame including a split within the frame. The camera housing also includes a latch mechanism extending along the frame from a first side of the split to a second side of the split, the latch mechanism operable in a closed configuration and an open configuration. A first distance between the first side of the split and the second side of the split when the latch mechanism is in the closed configuration is less than a second distance between the first side of the split and the second side of the split when the latch mechanism is in the open configuration.

A camera housing comprises a four-sided frame. A first side of the four-sided frame includes a first segment, a second segment, and a latch mechanism with a first latch component and a second latch component. The first latch component and the second latch component are pivotally coupled such that in a closed position, the frame securely encloses a camera and in an open position, the first segment and the second segment are separable.

The present teachings provide a camera housing that includes a first housing portion, a second housing portion, a hinge, a latch mechanism, and protrusions. The first housing portion forms a first portion of a cavity. The second housing portion forms a second portion of the cavity The hinge is located within the first housing portion so that the first housing portion is divided into a first piece and a second piece. The hinge movably connects the first housing portion to the second housing portion so that the second housing portion is movable relative to the first housing. The latch mechanism is movable between an open position and a closed position. The protrusion extend from a third housing portion, and the third housing portion is located opposite the first housing portion with respect to the cavity.
