CS218845B1 - Apparatus for emergency opening of lift doors of lift terminal stations - Google Patents

Abstract

The invention eliminates the so-called trapping of people in the elevator car in the event that the elevator car crosses the opening zone of the elevator terminal station during a malfunction and the elevator becomes uncontrollable for the user in the elevator car, for example when crossing the elevator limit switch, so that he cannot open the elevator shaft door and leave the car. The stated purpose is achieved by a device for emergency opening of the doors of the end stations of the elevator, which is connected by a rod to the door lock control lever itself, so that the deflection curve of the elevator car, which acts on the door lock control lever during normal stopping of the elevator car in the station, acts on the auxiliary control lever when crossing the opening zone of the end station, so that the door lock allows the shaft door to be opened.

Description

The present invention relates to a door lock for a door station of a terminal station. in the case of * ha-variation overrunning of the lift cage. the stopping zone is terminated by a stop station. Shaft doors are constructed in elevators; ,that; "They can only be opened if the cage is behind them in the station. The door leaf is secured against unwanted opening by a double shutter, which is controlled by a deflection curve placed on the elevator cage. The length of the working part of the deflection curve is selected according to the given length of the opening zone of the elevator station. The lift stops the lift from any cause outside the opening range, and the door cannot be opened. If it happens; thus, in the terminal station of the draft, when the cage goes off in the event of a failure, the electrical supply is automatically interrupted. ..proudu. .pr o i elevator. .the switch off and the elevator becomes uncontrollable until the operator arrives. Because in this case the lift cage is out of the level of the opening belt, the shaft door cannot be opened and the persons in the cage are imprisoned in a long time. The aforementioned serious drawback is eliminated by the modification of the shaft door of the terminal, the elevator in the part of the invention, the needle is essentially the use of an auxiliary control lever of the door closure, the deflection curve of the elevator cage will act upon the cage over the level opening zone of the lift terminal. The auxiliary door shutter control lever is coupled to the door shutter control lever itself, so that the movement of the lift curving curve that acts on the auxiliary control lever of the door shutter is transferred to the door shutter control lever itself. Thereby, the door closure is opened so that the persons traveling in the elevator will in this case be able to open the shaft door of the lift and leave the elevator car independently of the intervention of the elevator lifter.

Making an adjustment. door openings of the shutter doors of the lift stations according to the invention; in that, in the event of an elevator malfunction, when the elevator cage passes over the elevator end station, and the lift is uncontrollable for the 'User',! it will be possible for the user in the elevator car to leave the elevator car. The unwilling and very often long waiting times of people in the cabin, the tow, and the rescue are removed. In this case, the openings of the inventive 'undercover' are not changed in a flexible manner. the door, the door lock, or the security system itself, the elevator doors 1, is guaranteed; that sha-chetiriddape-ine can be opened during normal operation. the elevator, if there is no lift in the station. If the lift cage moves the elevator end station level, it will change. situafii'riIt is an elevator up to the ante® operation; this is signaled to the users of the lift by means of a signaling light in the elevator station by a permanently lit elevator car.

The drawing illustrates the use of an open-door elevator elevator of the present invention at a lower door shaft door. similar.

The door lock -1, which is fixed by the door shaft 17, is controlled by the door. curve 2, placed on the elevator, hu. When the elevator cage is stopped in the stationary manner, the deflection curve 2 acts on the door closure J via the control lever 3b of the container and is provided with a bracket 4 which is movably connected to the auxiliary control lever 8 on which it operates. diversion_of_your..2 at. the cages outside., the station's stop zone level. Both control levers 3, 6 are identical in design. It is attached to the chassis frame by means of a holder 8, on which a pin for the self-fastening of the auxiliary control lever 6 is rotatably mounted, which is carried out in the same manner as for the door closure. The distance between the levers 3, 6 is selected according to the working surface deflecting the control curve 2 of the lever, and in the case of the conductor, the conductor crosses the elevator; t OG OG af af (((((((((8 i i i i i i i i i i i i »» »» »» »» »» »» »» » the opening zone for safe protection of the case that is open to the door, in the case of a doorway, in the case of a doorstep, In the case of a stitching belt, the stitching and the stitching of the stitching of the twin-bandwidth bandwidth of the bandwidth of the bandwidth of the bandwidth of the bandwidth, the lever is provided with a cradle of the shape of the thread: 2 to .. pomoGK.-nou ;; and its movement by means of a control and control device in the case of a door, in which case it is possible to open the door by opening the door. t.
