A modular latch bar is formed from a first segment that is configured to be connected to a locker handle and one or more extension segments which are attached to the first segment. One of the segments has an elongated body having a front surface, a back surface, a first end and a second end; and a T-shaped locking tab extending from the first end. Another segment has an elongated body having a front surface, a back surface, a first end and a second end. This segment has a T-shaped recess on the back surface. The T-shaped recess is sized and configured to receive the T-shaped locking tab and create a friction fit between the T-shaped locking tab and segment having the T-shaped recess. A post may be provided in the recess that fits into a hole in the T-shaped locking tab to provide a snap fit connection.

A compact door barricade apparatus for use on doors is described. The apparatus is equipped with a protective inner case, outer case, door mount, an upper barricade, a lower barricade, barricade pivot links, handles, and barricade latches. Screws or lag bolts are used to mount the barricade latches to the door frame. The door mount connects the apparatus to the door. The barricade pivot links effectively link the movement of the upper barricade to that of the lower barricade. The movement of the handle disposed on the apparatus facilitates the synchronous movement of the upper and lower barricades across the width of the door and door frame, effectively securing individuals within a room.

A high security locking system can be used in a conventional pivot door adapted for use with a latch and deadbolt lock combination. The high security system can be a multi-point lock, received in a recess formed in a locking edge side of a door stile, cooperating with a linkage or other mechanism in a conventional deadbolt/location. The lock can be actuated with a keyed cylinder and thumb turn combination.

The present disclosure relates to a windows and doors assembly having a ventilation function and a horizontal contact function, and more particularly to a horizontal contact windows and doors assembly for crime prevention and security functions by preventing a window from being open even when the window is slightly open and it is possible to ventilate with the outside air. To achieve the objective of the present disclosure, the windows and doors assembly having a ventilation function and a horizontal contact function includes a window frame, and a windowsill in which the window frame is slidably installed, a handle rotatably installed on the window frame, an engagement unit provided on a lateral surface of the window frame, linked to movement of the handle, and moved in upward and downward directions, an engagement guide provided on the windowsill to face the engagement unit and configured to catch or not catch the engagement unit depending on a position of the engagement unit, and a horizontal moving device provided on at least one of a top surface or a bottom surface of the window frame, linked to the handle, and configured to make the window frame horizontally come into contact with the windowsill or to release horizontal contact depending on movement of the handle, and in this case, when a contact state of the window with respect to the windowsill by the horizontal contact device is released while a catching operation between the engagement unit and the engagement guide is performed, it is possible to ventilate through a gap between the window and the windowsill, the window is restrictly moved to form the gap, and the window is prevented from being freely open.

The present invention discloses a door lock structure for a pet cage. The door lock structure comprises a cage body on which at least one entrance and exit and a cage door matched with the entrance and exit are arranged. A plurality of pivot rings is arranged on one side of the cage door, sleeves a door frame on the edge of the entrance and is rotatable about the door frame. At least two limit sliding rods which are parallel to each other are arranged on the cage door, and a lock that is slidable on the limit sliding rods is installed on the limit sliding rods. The lock comprises a traveling mechanism that clamps the limit sliding rods, and a plurality of tension springs is installed on one side of the traveling mechanism close to the door frame. A plurality of lock bolt assemblies that moves synchronously with the traveling mechanism is also arranged on the traveling mechanism, and the lock bolt assemblies are matched with and locked with lock hole mechanisms provided on the corresponding door frame. The door lock structure is simple and exquisite in structure and design. Through the joint action of the traveling mechanism, the lock bolts and the tension springs, on the one hand, a plurality of lock bolts can be controlled at the same time; on the other hand, a plurality of parts of the cage door can be locked. The door block structure is simple and reliable and is easy to operate.

A fenestration hardware assembly includes a blade socket including a blade recess and an operator interface feature rotatably coupled with an operator housing. A latch blade is movably coupled with the operator housing. The latch blade is movable between deployed and withdrawn positions. In the deployed position at least a portion of the latch blade is received in the blade recess of the blade socket. In the withdrawn position the portion of the latch blade is recessed from the blade recess. The operator interface feature is rotatable between at least locked and unlocked configurations. In the locked configuration the latch blade is in the deployed position and received in the blade recess. In the unlocked configuration the latch blade is translated from the deployed position to the withdrawn position and withdrawn from the blade recess according to rotation of the operator interface feature.

An adjustable baffle includes a base having a room formed in its rear side, and a first through hole is defined through the base. A baffle is located in the room and movable in at least one movement direction within the room of the base. An elastic element is located to at least one side of the baffle that faces the at least one movement direction. The baffle includes a second through hole that is smaller than the first through hole. The baffle includes a guide face formed on one face thereof and located along the periphery of the second through hole. By the movable baffle, the lock latch of a door is guided by the guide face so that the lock latch can easily and smoothly insert into the recess of the doorframe.

Described is a device for constraining the opening of doors or windows comprising a guide body associated with a perimeter profile of a movable leaf and equipped with a slot; an operating arm articulated, at a first end, to a fixed frame, and a second end slidably connectable, by a pin, inside the slot of the guide body so as to allow a sliding stroke of the pin along the guide slot to define an open configuration with a limited angle of the leaf; the guide body is provided with two lateral openings facing each other made on the walls defining the slot to allow a free passage, through one of the openings, of the pin of the arm housed in the slot when the leaf is in a free open configuration; a locking lever or latch articulated to a base of the guide body and configured for locking the pin of the arm when it is positioned at an end of the slot of the guide body in the open configuration with a limited angle of the leaf; an operating rod slidably inserted along the body and having a pair of protruding walls configured to temporarily close, in use, the openings of the slot at least at the passage from the closed configuration to the open configuration at a limited angle of the leaf.

A lock indicator and a mechanical lock assembly, comprising: a switch; a transmitter coupled to a power source; and a bolt member moveable between a retracted position and an extended position with respect to the housing, wherein the switch is configured to engage the bolt member and is actuatable by the bolt member to determine the position of the bolt member, and the transmitter is configured to transmit a signal indicative of the position of the bolt member to a remote device.
