The present invention is directed to a door latching device that can be deployed in emergency situations to lock down a classroom, business, church, home or any other building. The device comprises a backing plate, a hinge body, a jamb hook and a hinge shaft that can pivot, thereby moving the jamb hook from a stored position to a latched position and vice versa. When the device is in a latched position, the device prevents a door from opening. The device can be moved from the stored position to a latched position, and conversely from the latched position to the stored position, with the use of only one hand and without the use of a specialized key.

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.

A sash lock for a sash window assembly is disclosed. The sash window assembly includes an upper sash window and a lower sash window. Each of the sash windows is mounted within opposed guide rails on a master frame. At least one of the sash windows is slidable within the frame relative to the other sash window. The sash lock comprises either a keeper, with a keeper opening, for mounting on a rail of one of the sash windows or a recess in the lower rail of the upper sash. The sash lock disclosed herein includes a housing having a hole, an actuator arm, and a cam having a cam element for receipt into the keeper opening or the recess. The locking assembly also includes a shaft extending through the housing hole and operably coupling the actuator arm to the cam.

A device for securing a door including a rotatable handle affixed to the door, a rotatable member affixed to the door, a catch, and a protrusion from the rotatable handle that is configured to lift the member when the member is engaged with the catch and the rotatable handle is rotated. A device for securing a door including a member configured to be rotatably attached to the door, a catch configured to be attached to a wall adjacent to the door and to receive the member, and a protrusion configured to be attached to a handle on the door and to lift the member when the member is in a closed position and the handle is rotated. A method for installing a device for securing a door with a handle, the method including affixing a member to the door so that the member can rotate, affixing a catch to a wall adjacent the door, the catch configured to receive the member, and affixing a protrusion to the handle, the protrusion configured to lift the member when the member is engaged with the catch and the handle is rotated.

An aircraft trolley retention device may include a retention latch with a shaft including a first component of an interlocking assembly and a sleeve including a second component of the interlocking assembly and configured to receive the shaft, and an interlocking assembly. The retention latch may be configured to actuate between a closed position and an open position. The interlocking assembly may be configured to guide the retention latch during the actuation between the closed position and the open position. The retention latch may be configured to retain an aircraft trolley within an aircraft trolley bay when the retention latch is in the closed position. A portion of the retention latch may be configured to be positioned in front of a striker plate corresponding to a handle of an aircraft trolley bay door of the aircraft trolley bay when the retention latch is in the open position.

A wire crate latch apparatus having, in a first embodiment, a pivoting member that is continually drawn to a closed position by gravity and that is deflected into a catch when the door having the pivoting member is swung closed. The latch apparatus further includes upper and lower stops to contain a distal end of the pivoting member and to hold the distal end in the position to hit an oblique portion of the catch when the door is closed. In a second embodiment, a sliding latch apparatus is deflected by a catch and is relatively inaccessible from inside of the wire crate by back plates on the latch and catch.

A fastener structure is provided, including a hollow sleeve, a rod body, and a hook assembly. The hollow sleeve is assembled on a first plate, and the rod body is inserted into the hollow sleeve. The hook assembly is rotatably assembled on the first plate, and includes a hook component and an elastic component. The hook component is adapted for being fastened to a positioning opening portion of a second plate, where a first side of the rod body is adapted to lean against the hook component. A first end of the elastic component leans against the first plate, and a second end of the elastic component is fixed on the hook component.

The present disclosure provides for a securable pet door. The securable pet door may comprise at least one door, at least one knob, one or more windows, at least one frame, and/or at least one hinge. The knob may comprise a latch for secure closing. When the pet door comprises at least one hinge, the hinge(s) may be inserted into at least one hinge recess so that the door may be securely locked via at least one locking mechanism. The orientation of the one or more elements of the securable pet door may be predetermined, securable, or customizable. The door may open from, slide into, revolve within, or move in some other non-limiting equivalent way from or relative to the frame. The frame may comprise at least one sensor. When the frame comprises at least one sensor, the sensor(s) may interface with at least one external device, such as a computing device, to actuate the at least one locking mechanism from a remote location.

A locking system for a utility vault including an I-beam extending across an opening in utility vault, a two-piece lid positioned in the opening over the I-beam, brackets positioned on opposite ends of each piece of the two-piece utility lid for engaging an inside wall surface of the utility vault and the I-beam, and a three-tier locking system positioned at an end of one piece of the two-piece lid to lock the lid to the vault including a L-bolt lock, a padlock and a lockable door on an upper surface of the lid.

A fenestration assembly includes a low-profile screen assembly including a fenestration frame and a sash movably coupled with the fenestration frame. The sash includes a daylight opening having a daylight opening profile. The low-profile screen assembly is coupled with one or more of the fenestration frame or the sash. The low-profile screen assembly includes a screen panel having a screen frame coupled along one or more of the sash or the fenestration frame, and the screen frame includes a screen frame inner perimeter. A screen membrane spans the screen frame and is coupled with the screen frame. The screen frame inner perimeter is outside of the daylight opening profile.
