Definitions

  • the present invention relates to cam systems for the joint opening and closing of an elevator car door and an elevator shaft door associated with the elevator car, comprising a pair of first and second engaging elements which extend substantially parallel and vertically and which are positioned between an open position in in which they are spaced a first horizontal distance, and a closed position in which they are spaced a second horizontal distance apart, the first horizontal distance being greater than the second horizontal distance, and further at least first and second hinge members which support the pair of engagement members in a parallelogram configuration and are rotatable to displace the engagement members between the open position and the closed position.
  • such driver systems are used between the closed position, in which the engagement elements, also known as “swords", are brought closer together so that the elevator door can be moved together with the elevator car in the elevator shaft, and the open position to be transferred .
  • the open position in an intended operating sequence, in a state in which the elevator car is stationary in relation to a hoistway door in a predetermined orientation, the swords are removed from one another in the plane parallel to the planes of the two doors, in order finally to cooperate with counter-entrainers attached to the hoistway door are provided so as to allow the elevator car door and the hoistway door to be opened and closed together.
  • a drive device is assigned to the elevator car, which is coupled to the carrier system and interacts in such a way that that when the two doors are opened, in a first step the engagement elements are first transferred from their closed position to their open position and then a common displacement of the doors coupled in this way is effected, while a reverse sequence of movements takes place when the doors are closed.
  • the closed position corresponds to the state in which the elevator car is vertically movable in the hoistway
  • the open position corresponds to the state in which the elevator car door and the hoistway door can be opened and closed together, so that the elevator car of the hoistway door is vertical must face immobile.
  • Driver systems used to date for this purpose are relatively complete, however, since in addition to the two engagement elements, a locking mechanism must also be provided for safety reasons, which, when the drive device is de-energized, drives the joint opening and closing of the elevator car door and the elevator shaft door and for transferring the Engagement elements between their open and their closed position blocked the elevator car door against manual opening.
  • driver systems of the type described above which are characterized by a simplified design with consistently safe operation and consequently offer savings potential both with regard to their production and their maintenance and operation.
  • the first joint element comprises a stationary first joint half for carrying the first engagement element and a pivotable second joint half for carrying the second engagement element, which is restrained by an elastic element to pivot from a pivoted Orientation to a deployed orientation are biased away from each other with a predetermined biasing force, the biasing force of the resilient member being selected to be greater than a sum of the weight forces of the hinge members and the second engagement member in the open position.
  • the second joint half is also assigned a guide section on a side facing away from the first joint half and the driver system comprises a guide curve, on which the guide section of the second joint half of the first joint element in the closed position of the engagement elements and at the beginning of a transition into the open position in order to counteract the preloading force of the elastic element, and a locking element which is pivotable between a closed position in which it prevents opening of the elevator car door and an open position in which it allows opening of the elevator car door, wherein it is in the closed position in an unactuated state, wherein the second joint half of the first joint element or the second engagement element is also assigned a triggering element, which is aligned with the locking element in such a way that it is in the open position of the engagement elements when the pivoted-in orientation of the Joint halves pivots the locking element into the open position, while it leaves the locking element in the closed position in the pivoted-out orientation of the joint halves.
  • the provision of the two joint halves of the first joint element creates a further degree of freedom with regard to the relative orientation of the two engagement elements and thus of the triggering element, so that only in a state in which, when the engagement elements are in their open position, they are against corresponding counter-elements of the Act elevator shaft door and consequently the elastic element is compressed, pivoting of the locking element into the open position is possible.
  • the stationary position of the first half of the joint and the second joint half that can be pivoted relative thereto are to be understood in such a way that the first joint half is assigned a pivot axis, around which the second joint half can in turn be pivoted, so that the stationary position mentioned only relates to this pivot axis and a relative pivoting movement related to it.
  • the first half of the joint itself is also pivotable in order to allow the engagement elements to pass between their open and closed positions.
  • the provision of the elastic element can also be dispensed with.
  • the first joint element also comprises a stationary first joint half for carrying the first engagement element and a pivotable second joint half for carrying the second engagement element, which, however, already causes a pivoting of one can be pivoted away from each other from a pivoted-in orientation to a pivoted-out orientation, wherein the second joint half is also assigned a guide section on a side facing away from the first joint half.
  • the second variant also includes a guide curve, against which the guide section of the second joint half of the first joint element rests in the closed position of the engagement elements and at the beginning of a transition into the open position, a locking element, which between a closed position in which there is an opening of the elevator car door is prevented and is pivotable in an open position in which it allows opening of the elevator car door, being in the closed position in an unactuated state.
  • the second joint half of the first joint element or the second engagement element is also assigned a release element, which is aligned with the locking element in such a way that in the open position of the engagement elements, when the joint halves are in the pivoted-in orientation, the locking element pivots into the open position while it is in the pivoted-out orientation of the joint halves, the locking element remains in the closed position.
  • the pivoting of the second joint half relative to the first joint half can be achieved, for example, by a suitable choice of the relative position of the pivot axis between the two joint halves, so that the weight of the components of the driver system assigned to the second joint half prevents this pivoting in an otherwise force-free state drives.
  • the pivoted-out orientation is assumed by the second joint half and the locking element consequently cannot be released.
  • the driver system can also include a stop element which is set up and arranged to limit the pivoting of the second joint half with respect to the first joint half in the direction of the pivoted-out orientation. In this way it can be ensured be that the second half of the joint in the pivoted-out orientation only pivots up to a predetermined angle relative to the first half of the joint.
  • an elastic preloading element can also be assigned to the locking element, which preloads the locking element into its closed position, the force exerted by the preloading element being greater than the effect of the weight force of the components carried by the second joint half.
  • the first and second joint halves consequently do not yet move apart directly into the pivoted-out orientation as a result of the effect of the weight of the components carried by the second joint half. Instead, when the engagement member transitions to its open position, the trigger member contacts the latch member, but the force exerted is insufficient to release the latch member against the action of the resilient biasing member.
  • the release element slides off the locking element due to the effect of the weight of the components carried by the second joint half and changes to the pivoted-out orientation if no corresponding counter-elements of the elevator shaft door act on the engagement elements of the driver system in their open position.
  • the locking element can only be triggered when the engagement elements of the driver and the counter-elements of the elevator shaft door are in engagement with one another.
  • the locking element must be formed with a corresponding shape, which causes the second joint half to slide and pivot into its pivoted-out orientation.
  • the second joint element can, in the same way as the first joint element, also comprise a stationary first joint half for carrying the first engagement element and a pivotable second joint half for carrying the second engagement element, in order to ensure the parallelogram configuration already mentioned in each of the operating states already described to be able to
  • the joint opening and Closing the elevator car door and the elevator shaft door can be carried out safely in the intended manner.
  • a further elastic element can be dispensed with in the area of the second joint element, since the corresponding function described above in the driver system according to the invention can be accomplished solely by the elastic element of the first joint element.
  • the second joint halves of the first and second joint element can be coupled to one another via a strut element for joint pivoting between the pivoted in and pivoted out orientation in order to ensure the correct functioning of the relative pivoting of the respective joint halves of the two joint elements.
  • this can comprise, for example, a joint body which is pivotably mounted on a base plate of the driver system and to which the first joint half is permanently assigned or formed integrally with it, while the second joint half is again attached to this joint body via a pivot axis may be mounted to allow pivoting thereof according to the invention.
  • shifting the engagement elements between the open and the closed position means that the joint elements can pivot by about 55° to 57°.
  • the open position of the engagement elements is often also referred to as the horizontal position of the joint elements.
  • the triggering element can be provided on an angle element assigned to the second engagement element, but in principle other embodiments are also conceivable, as long as the triggering element enables the corresponding movement of the second engagement element or the second joint half of the first joint element relative to the first Engaging element or the first joint half of the first joint element will run.
  • the triggering element can be guided in a curved elongated hole, as a result of which the corresponding mechanism of the driver system is given additional stability. It is important to ensure that the width of this slot is large enough to allow the intended displacement of the triggering element relative to the locking element in the pivoted-in and pivoted-out orientation of the two joint halves in the open position of the two engagement elements.
  • the guide section of the second joint half of the first joint element can comprise a roller, which is set up to roll on the guide curve. This ensures a clean movement between these two components.
