A latch system has a latch hook pivotably mounted in the housing between a closed position and an open position. It further includes an actuating lever pivotably mounted in the housing between a locked position and an unlocked position. When the actuating lever is in the locked position and the latch hook is in the closed position, the actuating lever maintains the latch hook in the closed position, and when the actuating lever is in the unlocked position, the actuating lever does not interfere with movement of the latch hook between the open position and the closed position. The system can further include a mechanical indicator, and when the actuating lever is in the locked position, the indicator provides a locked indication, and when the actuating lever is in the unlocked indication position, the indicator provides an unlocked indication.

The present invention discloses an electronic key storage case, comprising a housing, a cavity defined in the housing and configured for storage, a front panel configured for password input and disposed on the front of the housing, a locking mechanism and a control circuit disposed on an inner side of the front panel, characterized in that, the locking mechanism is an electronic lock, and comprises a driving circuit, a lock tongue, and a mounting assembly connected with the lock tongue, the driving circuit is configured to receive unlocking information from the control circuit and control an action on the lock tongue, the mounting assembly comprises a lock bracket, a rotating shaft located on the lock bracket, and a locking hook spring disposed on the rotating shaft, a locking hook groove is provided on the lock tongue, and the lock tongue is matched with the locking hook spring through the driving circuit, to obtain a degree of freedom of rotating forward or reverse rotation with the rotating shaft as a central axis to form two states of the locking hook groove engaged with or separated from the locking pin. In the present invention, the key case is opened automatically in an electronic lock manner, thereby being easier to use, providing a securer lock structure, and avoiding undesirably opening.

An apparatus for latching a door having a latching member; a retention cam wherein the retention cam further comprises an extended face and is rotatable about its axis; a spring; a locking member; an actuator; a push out member; and a driving member; wherein the actuator drives the driving member to remove the locking member from contact with the retention cam and the driving member drives the push out member to push the latching member away from the retention cam. The apparatus is capable of assisting both in the latching and unlatching of the device.

The invention relates to a locking device for the controlled locking and unlocking of authorized objects, meant to be used in particular within bicycle clamping and securing mechanisms of automatic systems, such as automatic bicycle rental stations. According to the invention, the device comprises a housing (1) consisting of a base plate (2) and a top plate (3), a rotary latch (5) which can move between an unlocked position and a locked position and an actuator controlled by an electronic control circuit, the device also comprising an anti-locking lever (8) which may rotate inside the locking device in the horizontal plane and which has a free end (8c) that can enter an anti-locking shoulder (5b) of the said rotary latch (5) for securing the locking device in the unlocked position, as well as an anti-unlocking lever (9) which may rotate inside the locking device in the horizontal plane and which has a free end (9c) that can enter an anti-unlocking shoulder (5d) of the said latch (5), for securing the locking device in the locked position, the said anti-locking lever (8) and anti-unlocking lever (9) being linked to each other by a traction spring (11) ensuring pulling of the two levers towards each other and maintaining them in this position, so that, in any moment, the end (8c or 9c) of only one of the said securing levers (8 or 9) is accommodated inside of the said blocking shoulder (5b or 5d) of the said rotary latch (5), while the respective free end (9c or 8c) of the other respective securing lever (9 or 8) is located outside the respective securing shoulder (5d or 5b) of the said latch (5), these positioning options making impossible the locking device to unlock or lock.

A latch (202) includes a catch jaw (210) which is operative to releasably engage a post. A release pawl (212) is operative to hold the catch jaw in a latched jaw position, and upon movement of the release pawl, enables the catch jaw to move to an unlatched jaw position. In an unlocked condition of the latch, movement of a handle (206) is operative to enable the latch to change from the latched to unlatched condition. The latch includes a keylock (240) and an electrical actuator (308). Each of the keylock and the electrical actuator are operative to independently change the condition of the latch between locked and unlocked conditions.

A door latch for a domestic electrical appliance includes a latch assembly that includes a locking element arranged to be displaceable between an unlocking position and a locking position, and an arresting element which moves from its release position into the arresting position as the door is closed. The arresting element in the arresting position can be locked by means of the locking element against movement into the release position and in the locked state prevents the closed door from opening. The latch assembly further includes an electric switch which, when the door is closed, responds to a movement of the locking element from the unlocking position into the locking position, and a switch auxiliary control member which, as the door is closed, is urged by the closing body from an active position against a restoring spring force into an inactive position.
