Definitions
- the present invention relates to an arrangement for the locking of the door of an elevator car as defined in the introductory part of claim 1, said arrangement being designed to lock the car door so that it can never be opened when the elevator is moving or has stopped between landings e.g. due to a power failure.
- DE-A-598 407 which describes an arrangement for the locking of the shaft doors of an elevator according to the first part of claim 1.
- the known arrangement allows to keep the shaft doors locked at all times when the elevator is moving or when it is standing between landings, while allowing the doors to be freely opened even during power failures when the elevator car is standing at landing.
- the actuating lever for unlatching the locks is kept away from the guide surface of the elevator car and is moved to be against the guide surface only when the elevator car approaches to the destined landing. For effecting unlatching and latching of the locks certain geometrical relations in the connection between the actuating lever and the lock have to be obeyed and an additional spring is needed.
- GB-A-352 750 Another state of the art for a safety locking device for lift shaft doors is represented by GB-A-352 750.
- This known device consists mainly of three members: A rotatable locking member, the unlocking lever and a control lever actuated by a control gear of the lift.
- the locking member is coupled with the control lever over the unlocking lever which is controlled by the cage.
- a specific object of the invention is to produce an arrangement for the locking of the door of an elevator car that keeps the elevator doors locked at all times when the elevator is moving or when it is standing still between landings, while still allowing the doors to be freely opened even during power failures when the elevator car is standing at a landing.
- the arrangement of the invention for the locking of the door of an elevator car comprises a lock which locks the doors the construction of the lock being in no way defined by the invention.
- the arrangement may comprise guide surfaces or equivalent areas or zones provided at the landings, allowing the presence of the elevator car at the landing to be recognized using a suitable means.
- the arrangement comprises an actuating lever for unlatching the lock, said lever being supported by the frame of the arrangement via a linkage and its motions controlled by said guide surfaces, and a transmission means connecting the lock and the actuating lever.
- the transmission means may be a suitable lever or linkage or a suitable connection consisting of ropes, chains or wire ropes.
- the locking arrangement of the invention may comprise an electrically operated actuator designed to shift the fulcrum of the actuating lever in such a way that the part of the actuating lever which uses the guide surface as a bearing will remain at a distance from said surface. and a counter device which moves the fulcrum in the opposite direction when the actuator is not operating, so that the actuating lever, leaning against the guide surface, will unlatch the lock.
- the electrically operated actuator may consist e.g. of an electromagnet whose attraction is applied to a suitable spindle.
- the counter device is preferably a spring connected to the other end of this spindle, so that when the magnet releases, the spring will return the spindle to the opposite extreme position.
- the counter device may also consist of some other known structure or device that returns the spindle to its other extreme position when the magnet releases.
- the essential feature of the locking arrangement of the invention is that the actuating lever producing the unlocking thrust motion uses the guide surfaces at the landings as its bearings. Therefore, when the elevator car is between landings, the actuating lever motions produced by the actuator or the counter device will not cause any motion of that end of the actuating lever which is linked with the lock; instead, in this case the actuating lever will only pivot about its joint. However. when the elevator car enters a landing zone, one end of the actuating lever will lean against the corresponding guide surface, with the result that its other end will move, transmitting an unlatching motion to the lock.
- the locking arrangement of the invention is that the fulcrum of the actuating lever is shifted in a controlled fashion in such manner that in one of its extreme positions the actuating lever cannot turn so as to unlatch the lock, whereas in the other extreme position the actuating lever can be turned so as to unlatch the lock, but only on condition that one end of the actuating lever leans against a guide surface. in which case the other end will undergo a motion that results in the unlatching of the lock.
- a locking arrangement as provided by the invention and illustrated by the drawings comprises a lock 1 whose locking bar 13 latches the lock plates 14 mounted on the elevator doors so as to render them immovable.
- a lever mechanism 4 comprising a straight bar 15, one end of which is pivoted on one end 8 of an actuating lever 7, the other end 10 of this lever being provided with a bearing roller 16 which, in certain positions, leans against the guide surfaces 2 provided in the landing zones.
- the actualing lever 7 is pivoted at point 17 on a bell crank 9, which in turn is pivoted at point 18 (fig. 2) on the frame of the device.
- the arrangement comprises an electromagnet used as an actuator 5 and a spring used as a counter device 6, said components being connected by a connecting rod 19.
- the bell crank 9 is linked with the connecting rod 19 by a lever structure 12 consisting of a first arm rigidly joined with the bell crank and a second arm linking the free end of the first lever with the connecting rod 19, so that when the connecting rod is moved by the electromagnet or the counter spring, the lever structure 12 will cause the bell crank 9 to turn about its fulcrum 18.
- Fig. 4 illustrates the principle of the arrangement of the bell crank 9 and the lever structure 12.
- the bell crank 9 consists of a rigid angular body pivoted by its elbow 18 on the frame of the arrangement, one end 17 of the angular body being connected to the actuating lever 7 and the other end 22 to the lever structure 12 linking this end of the bell crank with the connecting rod 19.
- the motion of the connecting rod 19 will cause the bell crank to turn about point 18, thereby shifting the position of the fulcrum 17 of the actuating lever 7.
- the locking arrangement of the invention functions as follows.
- a voltage is supplied to the magnet 5, which therefore attracts the connecting rod 19, causing the lever structure 12 to turn the bell crank 9 to the position shown in fig. 1.
- a clearance is produced between the bearing roller 16 and the guide surface 5. Because of this clearance. the floors where the elevator will not stop can be passed by without the bearing roller 16 hitting the guide surfaces, resulting in a smoother and quieter elevator travel.
- the spring-loaded locking bar 13 of the lock 1 is in its lower position, locking both door leaves 24 by means of lock plates 14.
- Fig. 3 illustrates a situation where the magnet 5 has released, i.e. the spring 6 has drawn the connecting rod 19 to the lower position. Since the actuating lever 7 is outside the region of the guide surface 2, no bearing is provided for the actuating lever 7, which is why bar 15 receives no thrust that would open the lock 1. This corresponds to a situation where the elevator car has stopped between landings e.g. due to a power failure.
- the arrangement of the invention allows the fulcrum 17 of the actuating lever 7 to be shifted to different positions in different situations, so that the actuating lever 7 will act in the desired manner, i.e. the door lock will only unlatch when the car is at a landing, and even then only if desired.
