The invention involves a keeper (20) to interact with a bolt (16) of a lock (10);

The keeper includes a bracket (22) for attachment to a structure, and a keeper rod (24) secured to the bracket, the keeper rod extending from one surface (27) of the bracket.

In the keeper, a shaft (32) is attached to the bracket and can rotate freely relative to the bracket such that it extends in a longitudinal direction (X); a blade (40) is mounted on the shaft (32) on one side of the bracket near the keeper rod in such a way as to always rotate along with the shaft; an angular position indicator (46) is also mounted so as to always rotate along with the shaft; the blade being so positioned that it can be rotated by the latch when the latch hooks on to or releases from the keeper rod, and the angular position indicator (46) being capable of indicating the angular position of the blade.

The invention is for example intended to be used on an aircraft door such as that of a helicopter.

A portable door securement device is provided having a member extending from a first end engaged to a doorknob of a door to a second end engaged with a floor adjacent the door, to prevent opening of the door in a direction toward the engaged member. A slot at a first end of the member engages around a stem of the door handle thereby preventing disengagement of the member from the door, and preventing opening of the door.

The present invention relates to a locking mechanism for a magnetic lock and including a locking body assembly. The locking mechanism includes a lock latch and a slide bar switch that move between an active and non-active positions. The lock latch cannot move freely in the active position, but can in the non-active position. The lock latch receives a magnet, and can move freely through magnetic force action. The locking body assembly includes a locking body and a locking plate. The locking body has a housings that form a cavity. When the locking mechanism and lock latch are fixed in the cavity, a hook portion of the lock latch can extend out of or retract into the cavity as the lock latch pivots, thereby engaging or disengaging with the locking plate, and either locking or unlocking the latch. The magnetic lock includes a key and the locking body assembly.

A barn door strike assembly to receive a barn door lock bolt, the strike assembly including a main body having a first side to contact a door frame, the main body including a bolt receiving aperture disposed within a second side of the main body to receive the barn door lock bolt therein, and a strike base disposed at the first side of the main body, the strike base including a main body contacting portion connected to the main body to attach the main body to the door frame, and a plurality of connecting members to fasten the main body contacting portion to the door frame, and a plurality of apertures disposed within the main body contacting portion to receive the plurality of connecting members therethrough.

An electric strike assembly includes a housing formed with a recessed portion therein, a keeper assembly pivotably mounted in the recessed portion of the housing, a lock leg pivotably mounted in the recessed portion of the housing and configured to rotate independently of the rotation of the keeper assembly, a block assembly having a blocking element configured to engage and disengage the keeper assembly, and to control engagement and disengagement of the blocking element with the keeper assembly. A method of capturing and releasing a latch bolt mounted in a door includes mounting an electric strike assembly in an associated door jamb and controlling an actuator to rotate an, actuator paddle to engage a blocking element such that the blocking element is engaged or disengaged from a keeper assembly.

A preload mechanism for a memory alloy wire actuator is disclosed that includes a rotating element configured to rotate about a pivot. The rotating element has a first contact point that is configured to couple to the memory alloy wire actuator such that contraction of the memory alloy wire actuator displaces the first contact point such that the rotating element rotates from a first position to a second position. The preload mechanism also includes a bias element with a first end that is coupled to a second contact point of the rotating element and a second end configured to be pinned relative to the pivot. The bias element has a line of action extending from the second end through the first end. The line of action has an offset distance that is the minimum distance between the line of action and the pivot. The offset distance has a first value when the rotating element is in the first position and a second value when the rotating element is the second position, the second value being smaller than the first value.

The present invention discloses a one-side rotating arc lock which comprises an adjusting assembly arranged on a first shell and a strainer arranged on a second shell. The adjusting assembly comprises an arc adjuster rotatably connected with the first shell. The arc adjuster is provided with multiple protrusions in the circumferential direction, used for adjusting the angle between the first and the second shell. Groove is provided on the protrusion. The strainer comprises an adjusting rod which matches the groove for locking the first and the second shell. The angle between the first and the second shell is adjusted through the arc adjuster rotatably connected with the first shell, and locking of the first and the second shell is achieved through the strainer. The one-side rotating arc lock of the preset invention not only has a simple structure and easy to operate, but also facilitates adjustment of the angle.

Disclosed is a strike assembly comprising a strike plate, a back plate and a thermal bar. The thermal bar can be situated between the strike plate and the back plate. The thermal bar can have a resistivity greater than the resistivity of the strike plate. Also disclosed is a strike assembly comprising a strike plate and a thermal bar. The strike plate can define a circular hole and can comprise a protruding sleeve extending from the strike plate. The strike plate can define an elongated slot. The thermal bar can define a first elongated slot and a second elongated slot. The circular hole of the strike plate can be axially in-line with the first elongated slot of the thermal bar. The protruding sleeve of the strike plate can be situated in the second elongated slot of the thermal bar.

An electric strike assembly includes a housing formed with a recessed portion therein, a keeper assembly pivotably mounted in the recessed portion of the housing, a lock leg pivotably mounted in the recessed portion of the housing and configured to rotate independently of the rotation of the keeper assembly, a block assembly having a blocking element configured to engage and disengage the keeper assembly, and to control engagement and disengagement of the blocking element with the keeper assembly. A method of capturing and releasing a latch bolt mounted in a door includes mounting an electric strike assembly in an associated door jamb and controlling an actuator to rotate an actuator paddle to engage a blocking element such that the blocking element is engaged or disengaged from a keeper assembly.

The invention relates to a lock holder (1, 23) for a motor vehicle lock, comprising a locking bolt (3, 25) and a mounting plate (2, 24), wherein the locking bolt (3, 25) can be fastened together with the mounting plate (2, 24) to a motor vehicle body, a cover cap (4, 5, 28, 29), wherein at least the mounting plate (2, 24) can be covered at least in areas by means of the covering cap (4, 5, 28, 29), and wherein the covering cap (4, 5, 28, 29) can be connected in such a way to the mounting plate that the cover cap forms at least in regions a surface area (18, 19) with the mounting plate (2, 24).
