A sliding bolt latch as disclosed herein is convenient to use and more reliable than counterpart door locking mechanisms of the prior art. A user may open and close a door with only one hand, but the present mechanism requires both a rotational movement and a translational movement of elements against a biasing force. Such requirement makes opening doors much more difficult for livestock confined to spaces by the closed doors. Also, the biasing of elements into the locking state makes embodiments of the invention less likely to unlock inadvertently in the presence of ambient vibrations.

A latch mechanism is provided that includes a housing, a cap, and at least one indicator. The cap may include a central axis and may be mounted for selective rotational movement relative to the housing about the central axis between a latched position and an unlatched position. The at least one indicator may be interposed between the cap and the housing, such that the cap is in covering relationship to at least a portion of the at least one indicator. The at least one indicator may also be mounted for radial movement outwardly from the central axis relative to the cap as the cap is rotated from the latched position to the unlatched position such that the cap is no longer in covering relationship to the portion of the at least one indicator.

A door assembly includes a frame having interconnected wires that define an opening for an animal to pass therethrough, and a door having interconnected wires and being coupled to the frame. A latch assembly has a handle structure and a pin. The handle structure is pivotable with respect to one of the door and the frame, and the pin is movable axially with respect to one of the door and the frame. A first wire of the plurality of wires of the frame forms a key hole assembly. The key hole assembly defines an aperture for receiving the pin when the door is in a latched position with respect to the frame. A tab assembly is formed by at least one wire of the door and is disposable behind at least one of the plurality of wires of the frame in the closed position.

A door assembly for an animal enclosure includes a frame having a plurality of interconnected horizontal and vertical wires that defines an opening for an animal to pass therethrough and a door having a plurality of interconnected horizontal and vertical wires and being coupled to the frame. The door is disposable between a closed position and an open position. A latch assembly is coupled to either the door or frame, and removably couples the door to the frame in the closed position. A blocking member is coupled to the door and located between at least two adjacent wires of the plurality of interconnected wires of the door. The blocking member is disposed adjacent to the latch member such that a portion of the latch member is in contact with the blocking member in a rest position.

A poultry cage door assembly includes a main body, a secondary body, and a bracket. The main body includes a main first lateral end extending from a main front side to a main rear side and from a main upper end to a main lower end. The main first lateral end includes a first keyed arrangement and a first bracket-receiving feature. The secondary body includes a secondary first lateral end extending from a secondary front side to a secondary rear side and from a secondary upper end to a secondary lower end. The secondary first lateral end includes a secondary keyed arrangement and a second bracket-receiving feature. The secondary keyed arrangement is configured to mate with the first keyed arrangement. The first bracket is mateable with the first bracket-receiving feature and the second bracket-receiving feature.

A fenestration system is disclosed. In some examples, the fenestration system includes one or more movable window sashes and a toggle assembly. In some examples, the toggle assembly operates to limit the degree to which the window sashes are opened or otherwise moved relative to one another. In some examples, a window sash may be opened a designated amount before the toggle assembly operates to obstruct it from being further opened.

An alarm system includes a latch assembly having a movable element mounted on one of an entry and a structural element, and a fixed element mounted on the other of the entry and the structural element, wherein the movable element is movable between an engaged position with the fixed element and a disengaged position from the fixed element. A magnet is provided in one of the movable element and the fixed element, and a coil is provided in the other of the moveable element and the fixed element. The magnet and the coil are positioned relative to each other so that an electric current is induced in the coil by the magnet when the movable element is moved between the engaged position and the disengaged position. An energy harvesting circuit connected to the coil converts the induced electric current into a supply voltage that powers the alarm system.
