Definitions

  • the invention relates to a stop device for preventing drift of an elevator car standing on a floor with car doors.
  • a disadvantage of the known device is that the pawls are magnetically swung out and in via a complicated linkage. This affects the reliability of the stop device provided as a safety device. With small car loads there is a risk of the elevator car drifting upwards. Upward drift cannot be avoided with the known device.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of avoiding the disadvantages of the known device and of providing a stopping device which meets the safety regulations relating to unauthorized car movements on the floor.
  • the advantages achieved by the invention can essentially be seen in the fact that the elevator car is protected against drift with the simplest means.
  • the stop device according to the invention is always switched on when the car doors are open and there is a direct danger to the elevator users.
  • the stop device can simultaneously serve to lock the car door when the car is outside a floor.
  • 1 denotes an elevator car with a car door consisting of at least one car door leaf 2 and a car door sill 3.
  • the elevator car 1 stands on a floor 4 and is secured against drift in the upward and downward direction by a stop device 5 arranged on the car door sill 3.
  • the stop device 5 is pivoted into the position shown in FIG. 1 by means of the car door leaf 3.
  • a floor door consisting of at least one floor door leaf 6 is also opened.
  • the cabin door leaf 2 is moved in a guided manner on the shaft door sill 3 or the floor door leaf 6 on a shaft element designed as a floor door sill 7 in FIGS. 1 to 5.
  • the floor door sill 7 projects into an elevator shaft 9, delimited by a shaft wall 8, in which the elevator car 1 is moved and represents a continuation of the floor slab.
  • the stop device 5 consists of an axis of rotation 10 penetrating the cabin door sill 3, a first load arm 11, a second load arm 12 and an actuating arm 13.
  • the first load arm 11 is at the lower end and the second
  • the load arm 12 is arranged at the upper end of the axis of rotation 13 in such a way that when the cabin door sill 3 is flush with the floor door sill 7, these can be freely pivoted by means of the axis of rotation 10.
  • the actuating arm 13 arranged at the upper end of the axis of rotation 10 projects into the path of the cabin door leaf 2 with an actuating cam 14 on the door side.
  • an actuating wheel can also be arranged that rolls on the surface of the cabin door leaf 2.
  • the cabin door leaf 2 pivots by means of the actuating arm 13 and the actuating cam 14 Load arms 11, 12 into the working position shown in FIGS. 1 and 3, in which the load arms 11, 12 project above the landing door sill 7 in the horizontal direction and thereby secure the elevator car 1 against drift in the upward and downward directions.
  • the second load arm 12 located above the landing door threshold 7 is loaded to a maximum by the weight of the elevator car 1 and the car load. If there is a drift in the upward direction, the first load arm 11 below the floor door sill 7 is loaded with a maximum of half the cabin load when the drive is switched off.
  • the return spring 15 can be a tension spring arranged on the car door sill 3 and on the second load arm 12 as shown in FIG. 2 or, as shown in FIG. 3, in each case a spiral spring arranged above and below the car door sill 3 and wrapping around the axis of rotation 10, this being between the car door sill 3 and a stop 16 is clamped.
  • the rotational position of the stop device 5 is monitored by a motion sensor 17, the signals of which are forwarded to the elevator control.
  • the stop device 5 consists of the actuating arm 13 and of the second load arm 12, which is connected to the actuating arm 13 and the axis of rotation 10 by means of a second deflecting arm 18.
  • the invisible first load arm 11 lying on the underside of the car door sill 3 is connected to the axis of rotation 10 by means of a first deflecting arm, so that when the actuating arm 13 is actuated by the car door leaf 2, both load arms 11, 12 are pivoted in the horizontal direction and protrude above the storey door sill 7.
  • FIG. 6 shows a variant of the arrangement of the stop device 5 according to the invention, which is arranged on the side of the elevator car 1 on a car platform 19 and, in the switched-on state shown, dips with the load arms 11, 12 into a shaft element arranged as a recess 20 on the shaft wall 8.
  • This arrangement variant is particularly suitable for multi-leaf telescopic doors that require more space in the door sill area.
  • a bracket arranged on the shaft wall 8 and projecting into the elevator shaft 9 can be provided, which in the switched-on state of the stop device 5 is towered above and below by the load arms 11, 12 in the horizontal direction.
  • the stop device 5 according to the invention is arranged on the car door sill 3 in such a way that the stop device 5 is switched on at the end of the opening process of the car door, that is to say shortly before the car door leaf 2 is opened.
  • the stop device 5 also serves to lock the door. It is designed in accordance with the first exemplary embodiment, but is arranged on the car door sill 3 in such a way that the stop device 5 is actuated at the beginning of the opening process of the car door, ie shortly after the opening movement of the car door leaf 2 begins.
  • a niche is arranged below the floor door sill 7, into which the first load arm 11, which is preferably extended in this embodiment variant, is immersed when the stop device 5 is switched on. When opened further, the actuating wheel 14 of the actuating arm 13 rolls off the front of the cabin door.
  • the actuating wheel 14 rolls again on the front of the cabin door until the actuating arm 13 swings in on the door edge opposite the door closing edge and switches off the stop device 5.
  • the first load arm 11 is pivoted out of the niche into the rest position, in which the elevator car 1 can be moved freely in the elevator shaft 9.
  • the car door can only be opened a gap width because the elongated first load arm 11 is pivoted at the beginning of the opening process and is in contact with the shaft wall 8 or the floor door. In this position, the further opening process of the cabin door is mechanically blocked by the stop device 5.
