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.

An apparatus including a chassis assembly having a housing, a spindle rotatably mounted to the housing, a spring collar rotatably mourned to the housing, a first biasing element rotationally urging the spindle toward a spindle home position, and a second biasing element rotationally urging the spring collar toward a spring collar home position. The apparatus may further include a handle mounted on the chassis such that the chassis biases the handle to a handle home position with a return torque. The handle is engaged with the spindle such that the first biasing element contributes to the return torque. In certain embodiments, the handle may further be engaged with the spring collar such that the second biasing element contributes to the return torque.

An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

An apparatus that at least assists in maintaining a lever or knob of a lock device in a relatively neutral and static position. The apparatus includes a biasing element that can be constructed from a compliant material that may at least assist in reducing impact forces between interfacing surfaces at least when the lever or knob is returns to the neutral, static position from one or more activated positions. The compliant nature of the damper can further alleviate issues relating to manufacturing tolerances and wear between interfacing surfaces.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, a trigger mounted rotatably to the housing, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The bolt is moveable between a first, closed position and a second open position. The trigger is moveable between a first position, in which the pin and roller are engaged with the bolt when the bolt is in its first position, and a second position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load is provided on the bolt, or manually by depressing the trigger to disengage the pin and roller from the bolt.

An electronic cabinet lock includes a lock housing, a lock body, a limiting member, a motor, and a main control board. The lock body and the limiting member are rotatably disposed in the lock housing, respectively. The motor is electrically connected to the main control board. The limiting member is driven by the motor through a transmission mechanism. The transmission mechanism includes a screw rod driven by the motor and a slider threadedly connected to the screw rod. The slider is slidably disposed in the lock housing, and is movably connected to the limiting member. The transmission mechanism has few components, which is a simple structure and convenient for assembly.

A lock with replaceable modules includes a first part and a second part which is connected to the first part. The lock has a latch bolt recess, a restriction recess and a deadbolt recess so as to selectively install a latch bolt, a restriction bolt and a deadbolt. A lock block is selectively installed in the restriction recess. The lock includes an installation slot which can be selectively oriented in different directions, and a core recess for receiving the deadbolt. The lock is selectively installed with different components by features of modularization and normalization so as to reduce inventory pressure. The customers may install the lock to entrance doors, gate doors, storage room doors, emergency doors, room doors, bathroom doors or the like.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, a trigger mounted rotatably to the housing, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The bolt is moveable between a first, closed position and a second open position. The trigger is moveable between a first position, in which the pin and roller are engaged with the bolt when the bolt is in its first position, and a second position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load is provided on the bolt, or manually by depressing the trigger to disengage the pin and roller from the bolt.

A lock trim assembly incorporates an escapement assembly comprising a control member and an escapement spring. The escapement assembly is movable between a locking position that blocks rotation of the spindle and an unlocking position that does not block rotation of the spindle. A coupling assembly that couples the handle to the spindle rotates between a default orientation and a blocking orientation. The default orientation allows the escapement assembly to move into the locking position. The blocking orientation blocks the escapement assembly from moving into the locking position. When the coupling assembly is in the blocking orientation, operation of the motor to drive the blocked escapement assembly into the locking position causes the escapement assembly to store energy in the escapement spring for forcing the escapement assembly into the locking position once the coupling assembly is reoriented back to the default orientation.

An apparatus including a chassis assembly having a housing, a spindle rotatably mounted to the housing, a spring collar rotatably mounted to the housing, a first biasing element rotationally urging the spindle toward a spindle home position, and a second biasing element rotationally urging the spring collar toward a spring collar home position. The apparatus may further include a handle mounted on the chassis such that the chassis biases the handle to a handle home position with a return torque. The handle is engaged with the spindle such that the first biasing element contributes to the return torque. In certain embodiments, the handle may further be engaged with the spring collar such that the second biasing element contributes to the return torque.
