It is difficult or even impossible to exercise this task, depending on the friction in the gear or the screw drive.

Abstract
Description
- The invention is related to a clutch for coupling a car door of an elevator car with a landing door of an elevator system in accordance with the preamble of
claim 1. - A conventional elevator system comprises two different sets of doors, i. e. car doors and landing doors. In general, each car of the elevator system includes at least one car door. Within each landing zone of the elevator system, at least one landing door is installed. Each landing door is located such that, when the car is stopped within the corresponding landing zone, the landing door is adjacent to a car door so that the interior of the elevator is accessible through the landing door and the car door provided that both doors are open. Under normal conditions, the landing doors are kept closed whenever the car is not present in the related landing zones. Instead of having actuators for each of the landing doors, a particular landing door can be coupled with the car door by means of a clutch which is arranged at the car door. If access to the elevator car through a particular landing door and a particular car door is desired, the elevator car is moved into the landing zone corresponding to that landing door and stopped. In addition, the car door is mechanically coupled with the landing door by means of the clutch when the car enters the landing zone. Afterwards, the landing door and the car door can be opened or closed by means of an actuator that is linked to the car door. Prior to moving the car to another landing door, the clutch is released, thereby uncoupling the car door and the landing door.
- In general, the clutch is arranged at the car door and comprises at least one coupling element, which is movable with respect to the car door between a first position and a second position such that the coupling element engages with the landing door, when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door. For uncoupling the car door and the landing door, the coupling element is moved towards the first position.
- For actuating the clutch, two different concepts are known. In a first concept, the clutch is linked to the actuator which drives the car door. Thus, the coupling element of the clutch and the car door are simultaneously driven by means of a single actuator. In a second concept, two actuators are provided, one of said actuators being dedicated for driving the clutch and the other actuator being dedicated for driving the car door. The latter concept is advantageous in that it allows more freedom in the timing and synchronization of movement of the coupling element since the actuation of the clutch is independent of the actuator which drives the car door.
- In EP 0 676 360 A1, a clutch for coupling a car door of an elevator car with a landing door of an elevator system is disclosed. The car door is movable with respect to the elevator car by means of a first actuator. The clutch comprises a coupling element and a second actuator. The coupling element is movable with respect to the car door between a first position and a second position by means of a second actuator such that the coupling element engages with the landing door, when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door. In particular, the coupling element consists of two vanes which are connected by means of a movable linkage. By means of the second actuator, the vanes are movable with respect to each other for establishing a mechanical contact of the vanes with rollers, which rotate about horizontal axles disposed at the top of the landing door, and which provide rotationally stiff coupling. As second actuator, a solenoid acting on an armature against the bias of a spring is used. The armature is arranged in parallel with respect to the vanes and in a sliding contact with one of the vanes. By activating the solenoid, the armature can be moved, thereby causing a movement of the vanes perpendicular to the direction of movement of the armature so that the distance between the vanes is changed. In order to control the movement of the vanes, a bias is applied on the vanes by means of a compressed spring being connected with both vanes. This clutch has several disadvantages. The sliding contact between the armature and one of the vanes is subjected to wear, thus limiting the lifetime and the reliability of operation of the clutch. In addition, the actual position of the vanes is influenced by the balance of at least four forces, i.e. the forces being provided by the solenoid and two springs and the friction between the armature and one of the vanes. Thus, it is difficult to control the motion of the vanes precisely and to ensure a given accuracy of control over a long time. In addition, due to the bias of the springs, the operation of the second actuator is not very efficient since the force generated by means of the solenoid must compensate the spring forces.
- In FR 2827266, a clutch for coupling a car door of an elevator car with a landing door of an elevator system is disclosed, the clutch being independently driven by means of a DC motor whereas the car door is opened or closed by means of a separate actuator. The force provided by the DC motor is transmitted to movable parts of the clutch by means of a gear or a screw drive. Due to friction in the gear or in the screw drive, a major part of the energy provided by the DC motor is lost. Thus, the efficiency of the clutch is reduced. Furthermore, if electric power is not available for driving the DC motor, it is difficult to operate the gear or the screw drive and, thus, it becomes difficult to actuate any component of the clutch. This is disadvantageous during the installation of the clutch in the elevator system. In the case of a power failure during operation of the elevator system, it may be necessary to manually operate the clutch. It is difficult or even impossible to exercise this task, depending on the friction in the gear or the screw drive.
- In view of the disadvantages of known clutches, it is the objective of the invention to provide a clutch which can be independently actuated by means of a separate actuator with high efficiency and with high precision.
- This objective is achieved by means of a clutch in accordance with
claim 1. - Advantageous embodiments are defined in the dependent claims.
- The clutch is designed for coupling a car door of an elevator car with a landing door of an elevator system, wherein the car door is movable with respect to the elevator car by means of a first actuator. The clutch comprises at least one coupling element and a second actuator. The coupling element is movable with respect to the car door between a first position and a second position by means of the second actuator such that the coupling element engages with the landing door, when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door.
- According to the invention, the second actuator is a linear motor.
- In this context, the term "linear motor" designates any motor comprising a motor primary and a motor secondary, wherein the motor primary and/or the motor secondary are movable in one dimension with respect to each other under the influence of a traveling magnetic field provided by the motor primary and acting on the motor secondary.
- The use of a linear motor in accordance with the invention has several advantages.
- Linear motors usually provide a high force density since the distance between the motor primary and the motor secondary primary can be kept small. Therefore, optimized linear motors provide a high efficiency. In addition, in the clutch in accordance with the invention, the coupling element can be directly coupled with the linear motor. Thus, the coupling element of the clutch can be directly actuated by means of the linear motor. Consequently, components such as a gear or a screw drive are not necessary for coupling the linear motor with the coupling element. Thus, the coupling element can be actuated with low friction. Therefore, the clutch in accordance with the invention can be efficiently actuated. In addition, the second actuator does not require much space.
- The position and the motion of the movable parts of a linear motor and the force provided by the linear motor can be precisely controlled on the basis of known technologies. Therefore, any movement of the coupling element of the clutch in accordance with the invention can be controlled with high precision. On this basis, the clutch can be operated with high reliability and with low noise.
- If electric power is not supplied, the motor primary and the motor secondary of the linear motor can be easily moved with respect to each other with low friction, for example by hand. This makes it easier to install the motor during the assembly of the clutch and simplifies manual operation of the clutch during power failure.
- In one embodiment of the invention, the motor primary is arranged at the car door and the motor secondary is arranged for force transmission to the coupling element. Alternatively, the motor secondary may be arranged at the car door and the motor primary may be arranged for force transmission to the coupling element.
- In another embodiment of the invention, the motor secondary is linked to the coupling element by means of a first pivot and the motor primary is rotatable about a second pivot being stationary with respect to the car door. Alternatively, the motor primary may be linked to the coupling element by means of a first pivot and the motor secondary may be rotatable about a second pivot being stationary with respect to the car door. In particular, the coupling element may comprise two vanes which are connected by means of a movable linkage such that the vanes are movable with respect to each other for establishing a mechanical contact of the vanes with the landing door. In each case, the first pivot may be arranged at the linkage or at one of the vanes. On this basis, it is possible to establish a connection between the linear motor and the coupling element, which connection is resistant to wear and, therefore, long-lived.

linear motor 40 can be actuated, thus leading to a linear movement of the motor secondary 42 with respect to themotor primary 41, as indicated by anarrow 47 in Fig. 2. Since the motor secondary 42 is connected with thelever 28 at thefirst pivot 45, the connectingelements linear motor 40. In addition, since themotor primary 41 is pivotally connected with thesupport 11, themotor primary 41 is turned around thepivot 46 upon an actuation of thelinear motor 40, as indicated by anarrow 48 in Fig. 2. - The
support 11 is provided withholes 12. Fastening means 13 may be passed through these holes in order to fix the clutch 20 at a car door. - Referring now to Fig. 3, the clutch 10 is fixed at a
