The electronic actuator of an electronic padlock according to the invention is arranged to turn the cam piece (5) to release the latch parts (7) from a locking state and to turn the cam piece (5) to hold the latch parts (7) in the locking state. The cam piece (5) comprises a cover part (5A) and a shaft part (5B). The cover part has a central hole (12) for the shaft part. The shaft part (5B) has a shaft pin (15), which is set into the central hole (12). The shaft part also has a connecting part 19, which is arranged to be in contact with the electronic actuator 4. The cam piece further comprises a spring (9) which is between the shaft pin (15) and the cover part (5A). The spring comprises a first end (9A) and a second end (9B). The first end 9A is arranged to be in contact with the cover part 5A. The second end 9B is arranged to be in contact with the shaft part 5B. The spring is arranged to transmit turning force of the electronic actuator from the shaft pin 15 to the cover part 5A in the direction of said locking state.

A vehicle hood lock device includes a base including a groove for entry of a striker, a latch that pivots between a restraining position and a release position, a locking lever engaging the latch, a torsion spring causing the latch to pivot in a direction toward the release position, and a sub-plate fixed to the base by a latch pin supporting the latch and a locking pin supporting the locking lever. The torsion spring includes a cylindrical portion. The sub-plate integrally includes a basal portion, a circumferential wall portion rising up from the basal portion in a pivot axis direction of the latch, facing the cylindrical portion in a radial direction thereof and restricting movement of the torsion spring in the radial direction, and a brim portion protruding outward in the radial direction from the circumferential wall portion and restricting movement of the torsion spring in the pivot axis direction.

The shaft part (5B) has a shaft pin (15), which is set into the central hole (12). The shaft part also has a connecting part 19, which is arranged to be in contact with the electronic actuator 4. The cam piece further comprises a spring (9,) which is between the shaft pin (15) and the cover part (5A). The spring comprises a first end (9A) and a second end (9B). The first end 9A is arranged to be in contact with the cover part 5A. The second end 9B is arranged to be in contact with the shaft part 5B. The spring is arranged to transmit turning force of the electronic actuator from the shaft pin 15 to the cover part 5A in the direction of said locking state.

A door lock, assembled in a door sheet, is provided, wherein the door lock has a latch, a first locking mechanism, and a second locking mechanism, wherein the door lock is adapted to be assembled on the door sheet through coupling the first locking mechanism and the second locking mechanism onto the latch. The first locking mechanism and the second locking mechanism have a spiral resilient member screw and abut on a bulge so as to lock the first locking mechanism and the second locking mechanism corresponding to the door sheet. At the same time, an engaging member of the second locking mechanism can both resiliently abut against an upper engaging member and a lower engaging member of the first locking mechanism, so as to limit the lateral movement of the first locking mechanism and the latch, which is not only assembled conveniently. Besides, the engaging and abutting structures among the engaging member, the upper engaging member, and the lower engaging member as well as the spiral resilient member and the bulge are very simple and effective.

A latch assembly includes a frame and a pawl including a surface for receiving a striker and being movably coupled to the frame between an open and a closed position. In the closed position, the pawl is positioned to retain the striker to the latch assembly, and, in the open position, the pawl is not positioned to retain the striker to the latch assembly. A spring guide is connected to the pawl and the frame, wherein, in the closed position of the pawl, the spring guide is configured to bias the pawl such that the pawl remains in the closed position, and in the open position of the pawl, the spring guide is configured to bias the pawl such that the pawl remains in the open position. One end of the spring guide is connected to the pawl, and the opposite end of the spring guide is unconstrained.

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.

The present invention relates to a mounting arrangement for fastening a shaft in a locking device, the mounting arrangement (1) comprising—a shaft (2) for insertion into a handle follower of a locking device; —a locking member (33) for fixating the shaft after insertion to prevent undesired removal from the handle follower, and—a release member (32) for releasing the locking member to enable desired removal of the shaft from the handle follower, wherein the locking member (33) is movable between a locking position for fixating the shaft in the handle follower and a release position, and wherein the release member (32) is operatively connected to the locking member for moving the locking member from the locking position to the release position. The invention also relates to a locking device (10) comprising such a mounting arrangement (1).

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.
