An animal enclosure including a plurality of members defining an interior of the enclosure. One of the plurality of members includes a first member having a frame structure and door assembly formed by a plurality of interconnected horizontal and vertical wires. At least two of the horizontal wires of the frame structure form a hook positioned inside the defined opening. The door assembly is coupled to the frame and moves between an open and close positions. The door assembly includes a first door and a second door removably coupled to one another. The enclosure also includes a latch assembly for releasing the door assembly from the frame structure. In the close position, at least one horizontal wire of the first door and at least one horizontal wire of the second door are coupled to the hooks formed by the at least two horizontal wires of the frame structure.

Firearm associated electronic devices are provided. In one aspect a firearm associated device has a housing having a holding area and an opening through which a removable component may be positioned in the holding area, a door movable relative to the housing and having a door latch that moves along a path as the door moves and a housing latch movable between a first latch position where the housing latch is not in the path to a second latch position where the housing latch blocks movement of the door latch from a first range of positions where the door prevents the removable component from passing through the opening to a second range of positions where the door does not prevent the removable component from passing through the opening. A housing latch biasing member biases the housing latch into the second latch position. When the door latch is in the first range of positions and the housing latch is in the second latch position the door latch is movable along the path but is blocked by the housing latch from passing to the second range of positions.

Latching motion transfer arrangements may be used to raise an object up and out of the engagement with the ground or other support surface and to lower the object back onto the ground or other support surface. In one exemplary embodiment, the mechanism is caused to lift and latch by applying force in a first direction, a first time, and is caused to release and lower by applying force in the first direction, a second time.
