The invention relates to a motor vehicle lock, in particular a motor vehicle door lock, which is equipped with a locking mechanism (1, 2) composed, essentially, of a rotary latch (1) and a pawl (2). Furthermore, a securing device (5, 6, 7, 8) and and an emergency actuation element (9, 10, 11) for the securing device are realized. The securing device (5, 6, 7, 8) has at least one securing lever (5), which can be acted upon both by a first motor drive (7) and by an emergency actuation lever (10) as part of the emergency actuation element (9, 10, 11). According to the invention, the first securing lever (5) has a spring (5a) for positioning the first securing lever.

The door lock according to the invention comprises a lock body, a bolt, a follower, a driver on both sides of the follower, and a latch solution to connect at least one of the drivers in force transmission connection and out of force transmission connection with the follower. The door lock further comprises a baffle plate between the follower and the driver at least on one side of the follower. The baffle plate comprises at least one support surface, which is set against the lock body or against a part which is connected to the lock body in a fixed manner. The baffle plate can thus not be rotated in relation to the lock body. A baffle plate which cannot be rotated prevents turning force from being transmitted from the driver to the follower.

Personal restraints are described, including a user-accessible button that can be pushed in sliding a lock bar into a double lock position.

The proposed handcuff in the invention employs an innovative locking mechanism, which stops further tightening of the handcuff when the force applied on the wrist of hand or ankle of foot is greater than 1.5 lbs (or any preset value), and prevents physical injuries from over-tightening without compromising the restrain. The handcuff is 50% faster in restraining by automatically locking instead of manually push-to-locking. The handcuff has the same shape/size/cost of the handcuffs currently used by police officer, and is compatible with current training procedure or SOP.

An electronic cylinder lock has a main body. The main body is provided with a rotary cam. A first shaft is connected to the rotary cam. The first shaft has a first engaging portion. The main body is provided with a second shaft. The second shaft has a second engaging portion. A control lever is connected to the second shaft. A driving source is connected to the control lever. The driving source can drive the control lever to pull the second shaft to approach the first shaft, so that the second engaging portion is engaged with the first engaging portion, thereby improving the joint stability between the second engaging portion and the first engaging portion.

A lock for a lid of a receptacle such as a trash can comprises a gravity pin, a torsion spring, a lower pin, and a latch. The lock can be mounted to the receptacle and lid. The gravity pin and latch operate to substantially prevent the receptacle lid from inadvertently opening, while automatically allowing the lid to open when the receptacle is inverted. Also provided are lids and receptacles comprising lid locks as provided herein.

A lock device for a waste receiving device, and a waste receiving device having such a lock device, where the lock device includes an upper lock part to be fastened on a cover of the waste receiving device and a lower lock part to be fastened on a container of the waste receiving device. The upper lock part has an upper lock part housing, a locking mechanism and a first locking element. The lower lock part has a lower lock part housing and a second locking element. The second locking element is pivotable about a swivel axis between a blocking position and a release position, whereby in the blocking position the second locking element cooperates with the first locking element in such a way that the cover is blocked.

Discloses is a lock for releasably locking a first component to a second component. The lock includes a driving assembly, configured to be installed on the first component and including a rotatable cylinder housing; a transmission assembly, including a cylinder core which insertable by a key and is in torque-transmission connection with the driving assembly; and a locking assembly, connected with the transmission assembly and having a first position decoupled from the second component and a second position coupled with the second component, wherein the driving assembly can move relative to the first component and drive the locking assembly by means of the movement to complete the locking, and the locking includes: making the locking assembly move to the second position from the first position and be locked there.

A latch assembly comprising an elongated flat latch slider slidable along a first axis between a first position and a second position in relation to a main latch, wherein the latch slider is provided with a protruding lug; a lock arrangement comprising; a body moving between a locking position and an unlocking position, wherein in the locking position a portion of the body is preventing movement of the lug along a path in parallel with said first axis, and in the unlocking position the lug can be moved along said first axis; and an electrically powered device connected to the body for moving the body between the locking position and the unlocking position.

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.
