A door rod assembly for multi-point latch uses. The desire in the use of this door rod assembly is to essentially air seal a cabinet or closing from exposure to the air. Such air can include dust, dirt, noxious chemical fumes and the like. The devices seal cabinets, rooms, or the like from such contaminants. Assembly of the rod assembly is facilitated by the novel rod guide utilized in the assembly.

The present disclosure relates to an interlock mechanism for automatically locking and unlocking a lock system of an electrical cabinet based on the state of bolted pressure contact switches housed within the electrical cabinet.

A locking apparatus for a pet cage is disclosed. The locking apparatus comprises a turntable rotatable about a central axis of rotation; at least one elongate metal lock bar, where elongate metal lock bar is configured to extend along a radial line originating from the axis of rotation of the turntable and a connecting member for operably connecting the elongate metal lock bar and the turntable. The connecting member comprises a forwardly extending portion for receiving a front section of the elongate metal lock bar and fixing a retained end of the elongate metal lock bar to the connecting member and a rearward extending portion which extends parallel with and is outwardly offset from the forwardly extending portion. The connecting member also includes a linear conversion mechanism arranged between the turntable and the rearward extending portion of the connecting member; the linear conversion mechanism configured to convert rotation of the turntable about the axis of rotation to linear movement of the connecting member in the same direction as a longitudinal direction of the elongate metal lock bar.

A lock for a pet transporter is provided. The lock includes a gear drive set, at least one pair of lock rods, and a chassis. Each lock rod includes an inner end including a rack portion having a structure for engaging with a transmission gear of the gear drive set, each transmission gear having a structure for engaging with a main gear of the gear drive set such that rotation of the main gear drives rotation of each engaged transmission gear. In use, rotation of the main gear in a first direction synchronously drives the first pair of lock rods into the corresponding lock holes to engage the lock, and rotation of the main gear in an opposite direction synchronously drives the first pair of lock rods out of the corresponding lock holes to disengage the lock.

A latch mechanism includes an operation unit, a connection unit extending in one direction and having one end connected to the operation unit, a restriction unit restricting the connection unit such that the other end of the connection unit moves to one side in the one direction, in a case where the operation unit is moved to one side in an intersecting direction intersecting with the one direction, a moving unit connected to the other end of the connection unit, extending in the one direction, and moving from a first position to a second position as the other end of the connection unit moves, and a meshing unit meshing with the moving unit arranged at the first position, and releasing meshing with the moving unit arranged at the second position.

A lock mechanism according to an embodiment includes an engaging portion, a hook, and a pressing portion. The engaging portion is provided in any one of a housing and a door that is configured to open and close a housing opening portion of the housing. The hook is provided in the other one of the housing and the door to be rotatable around a rotation axis, is engageable with the engaging portion, and is normally disengaged from the engaging portion by its own weight. The pressing portion is provided separately from the hook and is configured to press the hook. The hook includes a hook side engaging portion that is configured to engage with the engaging portion with the rotation axis interposed therebetween, and a hook side pressing portion that is configured to cause the engaging portion to engage with the hook side engaging portion by being pressed by the pressing portion.

A security reinforcement system for a door assembly having a door frame with first and second spaced-apart vertical structural supports and a door hinged thereto has first- and second-channel base plates respectively mountable to the first and second vertical structural support. Pivotally attached to the first and second base plates, respectively, are first and second opposed pluralities of security arms which rotate from a retracted position to an extended position in which security arms of the opposed pluralities extend toward each other across a portion of the door, reinforcing the door when first and second actuator arms operatively coupled to the first and second pluralities, respectively, are rotated from a vertical position to a horizontal position and are releasably coupled together by a sleeve.

A retention bracket configured for use with a latch mechanism including a laterally extending housing. The retention bracket includes a first wall, a second wall, a collar, and a deformable section. The first and second walls are longitudinally offset from one another and are structured to receive the housing therebetween. The collar extends longitudinally outward from one of the walls and defines an opening having an effective diameter. The deformable section has a natural state in which the effective diameter is a first diameter, and a deformed state in which the effective diameter is a second diameter greater than the first diameter.

A latch mechanism includes an operation unit, a connection unit extending in one direction and having one end connected to the operation unit, a restriction unit restricting the connection unit such that the other end of the connection unit moves to one side in the one direction, in a case where the operation unit is moved to one side in an intersecting direction intersecting with the one direction, a moving unit connected to the other end of the connection unit, extending in the one direction, and moving from a first position to a second position as the other end of the connection unit moves, and a meshing unit meshing with the moving unit arranged at the first position, and releasing meshing with the moving unit arranged at the second position.

An electric locking device for an operable/closable member attached to an opening portion, includes a biasing member which biases a pair of rods in a direction in which the rods are brought into engagement with a pair of locking portions, an actuator for sliding the rods to disengage from the locking portions, the actuator having a case having an opening portion, a motor disposed within the case, a worm rotated by the motor and a worm wheel supported rotatably on the case and interlocked with the worm for rotation. The worm wheel has a rotating portion projecting outwards of the case from the opening portion, and proximal end portions of the rods are assembled individually to the rotating portion so as to move in an associated fashion, causing the rods to slide in a synchronized fashion in opposite directions to each other.
