INTERLOCK MEANS FOR ELEVATOR CAR ENCLOSURES

摘要

The invention relates to interlock means for elevator car enclosures which can be used to anchor the car at particular points in order for maintenance work to be carried out, the elevator frame and car being suspended from said points. The inventive means comprise a bolt housing (1) which is solidly connected to the car frame and which supports a safety electrical contact (2) and a safety bar (3) disposed on the top thereof. When the bar is moved, the contact (2) is activated, thereby preventing the car from being actuated. The bar (3) is securely fixed to a section (4.1), which is disposed in the lower part of the mount and connected to the lower arms of said mount, or to a similar section (4.2) which is disposed in the lower part of the pit and connected to the arm (7) of the first rail support (6).
