The case forms a special axle (4) provided with a fixed permanent magnet having mechanical connection in the case. A key is fixed on the movable permanent magnet and transmits rotative movement to an unlocking system (11) of a lock (12) when the special key is applied on the male end part. The male end part and the axle are at cylindrical shaped ends in the case that includes housings for the key. #CMT#USE : #/CMT# Device for securing a lock of a lift. #CMT#ADVANTAGE : #/CMT# The device utilizes the special key to permit an authorized person to unlock the lock of a lift, thus ensuring safety of the user and normal operation of the lift, thus avoiding risk of partial or total deterioration of components of the device. The device can be manufactured in a simple manner, and can be maintained without need of labor. The device can be easily installed to the unlocking system or to the lock, and fitted in the lock during the fabrication, such that the device is miniaturized. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a general schematic view of a device for securing lock of a lift. 3 : Male end part 4 : Special axle 6 : Case 9 : Special key 11 : Unlocking system 12 : Lock #CMT#INDUSTRIAL STANDARDS : #/CMT# The male end part is defined according to NF EN 81-1 standard. |
