Abstract
In one embodiment of the present invention, a lock device is adapted to unlock a lock by transferring a lock catch from a locking position to a releasing position. The device includes an electric motor, which is mechanically connected to an axle via at least one transmission device, and rotation of the axle actuates the lock catch. In at least one embodiment, the transmission device includes a weakening structure adapted to break and disrupt the mechanical connection between the electric motor and the axle if a threshold force is exceeded.
Claims24
A lock device adapted to place a lock in an unlocked state by transferring a lock catch from a locking position to a releasing position, said lock device comprising:
- an electric motor of the lock device mechanically connected to an axle via a transmission device of the lock device, rotation of the axle actuating the lock catch, said transmission device including a gear, said gear including a weakening structure adapted to break and disrupt the mechanical connection between the electric motor and the axle upon a threshold force being exceeded such that the lock is placeable in the unlocked state by manual turning of a lock knob connected with said axle.
A method for mounting a lock device to a door leaf comprising:
- mounting a fastening plate having an annular projection that projects toward and is configured to receive the lock device at a plurality of positions, to the door leaf,
- selecting a mounting position from among the plurality of positions, and
- mounting the lock device to the fastening plate, wherein connection between the fastening plate and the lock device allows for positioning of the lock device at different angles relative to the fastening plate.
A method for mounting an electrically driven lock actuating device to a door leaf of a door, the door having a lock with an internal lock mechanism inside the door leaf, and a lock catch which is actuatable by rotation of an axle of said internal lock mechanism, the lock actuating device having an electric motor and a transmission for connection to said internal lock mechanism, the method comprising:
- providing a circular fastening plate;
- attaching a base plate of the lock actuating device to the door leaf next to the lock catch by fastening the base plate directly to the circular fastening plate, thereby allowing the base plate to be mounted in a plurality of angles around the periphery of the fastening plate;
- and
- connecting the transmission of the lock actuating device to said internal lock mechanism, wherein actuation of said electric motor will cause actuation of said lock catch.
An arrangement for mounting a lock device to a door leaf, comprising:
- a fastening plate adapted for fastening to the door leaf, wherein the fastening plate further comprises means for fastening the lock device to the fastening plate, and wherein said means for fastening the lock device to the fastening plate comprises an annular projection having a circumferential groove for mating cooperation with at least one fastening device of the lock device, wherein the lock device may be arranged at defined or optional angles relative to the fastening plate.
An arrangement for allowing mounting of a lock device in different directions to a door leaf having a lock catch, the arrangement comprising:
- a circular fastening plate adapted to be fastened directly against a surface of the door leaf, and for attaching a base plate of the lock device to the door leaf next to the lock catch by fastening the base plate directly to the circular fastening plate, thereby allowing the base plate to be mounted in a plurality of angles around the periphery of the fastening plate.
