An animal enclosure includes a kennel body and a door assembly. The door assembly includes a door frame and a door pivotally attached to the door frame. The door frame is secured to the kennel body at an opening. The door is moveable between an open and a closed position. The door includes a first latch having a first latch bolt engaging the door frame at a first latch location. The door also includes a second latch having a second latch bolt engaging the door frame at a second latch location. The door also includes a third latch having a third latch bolt engaging the door frame at a third latch location. In some embodiments, the first latch bolt extends horizontally toward the door frame, and the second and third latch bolts extend substantially vertically from the door toward the door frame in opposite directions.

A cam lock for cabinets, drawers, drug cabinets, credenzas, sliding doors, lockers, mail boxes and other door type applications is compact in size, fits an existing cam lock opening and provides electronic access via a keypad or other electronic access. Using batteries, such as AAA size batteries or smaller, the lock has electronics that release a lock turn knob or handle when the correct code is entered. Preferably a set of electronic contacts is included at an accessible position on the lock housing to allow both master access and power jumping with a common manager's implement, for situations of lost codes and/or battery failure. In a particular embodiment the lock is long, narrow and low in profile so as to fit on the margin of a steel or wood file cabinet, compatible with the cam lock opening already provided. The locks, NFC-enabled, can be used in securing delivery boxes to enable delivery access, when authorized.

A locking piece assembly adapted for installation in a cylindrical lock and meant to engage a locking mechanism comprises a locking piece and a lock button. The locking piece has one end adapted to engage the locking mechanism and an opposite end with a connecting hook. The lock button has an aperture adapted for attachment to the locking piece connecting hook, and can be depressed to move the locking piece inward to engage the locking mechanism after the locking piece assembly is installed in the cylindrical lock. The lock button can be installed onto the locking piece by hand, specifically by inserting the connecting hook into the aperture on the lock button, pivoting the lock button with respect to the locking piece, and placing the locking piece and lock button into alignment. After installation, the connecting hook is held in place to prevent separation from the lock button aperture.

Systems, devices, and methods of locking a lockable volume. The lock may comprise a bolt and a slider. The slider moves linearly to move the bolt in position to engage a securement feature. The engagement of the bolt with the securement feature secures the securement feature, thereby locking the door to which the securement feature is attached.

The invention relates to a mechanical lock (37) for a plurality of keys (26) that can be authorized with a different code (39), with discriminated opening using a selection device (1) that can be activated manually from outside, a signaling element for displaying the selected code (2) (3), a manual closure (4) and locking (19) (15) mechanism, integrated with a modular set of lockers (FIG. 15) for delivery home and collection of parcels. The invention allows the use of a limited number of modular lockers for a larger set of users without requiring computer applications, electricity or an internet connection during the delivery, which is especially for common areas of communities of residents, building lobbies, housing estates, shared spaces or offices.

The invention relates to a door lock with a locking element (1) for locking the door (3) in a closed state and a fastening element (2) for fastening the locking element (1) to the door (3), wherein that the fastening element (2) has an adjustable adjustment device (4) to compensate for different door thicknesses.
