연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

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.

1. 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. 2. The lock device of claim 1, wherein the transmission device further includes a gear wheel comprising a central region, a peripheral region, and an intermediate weakening region including the weakening structure. 3. The lock device of claim 1, wherein the weakening structure comprises a structural weakening. 4. The lock device of claim 2, wherein the weakening structure comprise an adhesive bond, releaseably bonding the central region to the peripheral region. 5. The lock device of claim 2, wherein the weakening structure comprises at least one structure extending radially between the central region and the peripheral region. 6. The lock device of claim 1, further comprising means for monitoring the current consumed by the electric motor. 7. The lock device of claim 6, further comprising means for evaluation of the monitored current and storage means for storing a preset value regarding the current. 8. The lock device of claim 7, wherein the lock device is capable of determining whether the lock device is in a locked state or not based on a comparison between the monitored current and the preset value. 9. 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, andmounting 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. 10. 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; andconnecting 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. 11. The method of claim 10, the door having a protective plate situated between the door leaf and a lock knob of the lock, wherein the method comprises replacing the protective plate with said circular fastening plate. 12. The method of claim 11, wherein the base plate is fastened to the circular fastening plate using pre-existing fastening screw openings used to fasten the protective plate to the door leaf. 13. The method of claim 11, comprising initially temporarily removing the lock knob from the lock. 14. The lock device of claim 1, wherein the electric motor includes a transmission axle and the transmission device is mounted on an end of the transmission axle. 15. The lock device of claim 1, wherein the weakening structure includes a frangible portion. 16. The lock device of claim 2, wherein the weakening structure comprises a structural weakening. 17. The lock device of claim 3, wherein the structural weakening includes apertures, recesses or cavities in the weakening region. 18. The lock device of claim 7, wherein the preset value is a threshold value or a reference curve. 19. The lock device of claim 16, wherein the structural weakening includes apertures, recesses or cavities in the intermediate weakening region. 20. The lock device of claim 16, wherein the weakening structure comprises at least one structure extending radially between the central region and the peripheral region. 21. The lock device of claim 19, wherein the weakening structure comprises at least one structure extending radially between the central region and the peripheral region. 22. 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. 23. The arrangement of claim 22, wherein the fastening plate comprises projections extending on the side facing, in a mounted position, the door leaf for increasing the friction between the fastening plate and the door leaf. 24. 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.
