Definitions

  • the present invention relates to an elevator with a lowerable cabin ceiling part, an elevator car with a lowerable cabin ceiling part and an elevator car ceiling with a lowerable cabin ceiling part
  • Retractable cabin ceilings are used differently in an elevator. For example, trapped passengers can be freed from an elevator car via the lowered cabin ceiling, or service technicians can use the lowered cabin ceiling to gain access to components of the elevator that are to be maintained.
  • a cabin ceiling also serve to ensure a security space between the elevator car and the shaft end by the lowerable car ceiling is connected to an automatic triggering, which triggers in the unlawful presence of a person on the car roof.
  • Such a lowerable cabin ceiling usually consists of a ceiling frame and a lowerable cabin ceiling part.
  • the ceiling frame frames the cabin ceiling part.
  • the cabin ceiling part is suspended by a lowering mechanism on the ceiling frame.
  • the cabin ceiling part is held, for example by means of a bolt in its rest position at the height of the ceiling frame.
  • the patent DE 101 04 351 A1 shows a lowerable cabin ceiling part for maintenance, which is suspended on a lowering mechanism.
  • the lowering mechanism consists of two subsystems. Each of these subsystems, in turn, has two rod-shaped elements that form a scissors-like structure. Here are the two rod-shaped elements each rotatably connected to each other approximately at its center by means of a hinge.
  • the two subsystems are coupled at the ends of the rod-shaped elements with the ceiling frame and the cabin ceiling part.
  • the aim is to create the safest and most functional workplace for the service technician.
  • This includes, for example, a platform that is as stable as possible, good access to the components to be serviced in the shaft and on the cabin roof, as well as quick and easy lowering of the cabin ceiling.
  • an elevator has an elevator car, an elevator car ceiling covering the elevator car, a car ceiling part forming the elevator car ceiling, a ceiling frame framing the car ceiling part, a mechanism connecting the car ceiling part to the ceiling frame, and to the car ceiling part from an upper rest position to a lower position inside the elevator car, and at least two subsystems which are components of the mechanism.
  • a subsystem has at least two rod-shaped elements which prevent the cabin ceiling part from rotating about a horizontal axis of the cabin ceiling part and which are rotationally coupled to the cabin ceiling part and the ceiling frame.
  • First coupling points of the at least two rod-shaped elements of a first subsystem with the cabin ceiling part lie on a first straight line and second coupling points of at least two rod-shaped elements of a second subsystem with the cabin ceiling part lie on a second straight line.
  • the first and second straight lines intersect.
  • the advantage of such an elevator is that both tilting directions of the cabin ceiling part, which serves as a platform, are rotationally secured by the subsystems.
  • the cabin ceiling part thus remains in a horizontal position during the entire lowering process.
  • the cabin ceiling portion remains in its lower position upon entering the same in a stable position.
  • the cabin ceiling part not tilted thanks to the always horizontal position of the cabin ceiling part during lowering.
  • the lowering or lifting of the cabin ceiling part is independent of the point of attack of the service technician. The maintenance technician can thus easily move the cabin ceiling part from a position near the elevator car door comfortably and controlled vertically.
  • the rod-shaped elements of the subsystems underlying the ceiling frame leave a clearance which the cabin ceiling portion passes from the upper rest position to the lower position during the lowering operation during the lowering operation.
  • the cross section of the elevator car can be used optimally. Because the components of the Absenkmechanismus need no space outside the base of the cabin ceiling part or the ceiling frame, if necessary, the base of the cabin ceiling part can reach approximately the extent of the base of the cabin interior. Thus, the maintenance technician can easily and conveniently reach all the elements to be serviced in the shaft without having to lean far or even have to stand on the cabin roof or the ceiling frame.
  • At least one subsystem has a return element which assists the lowering movement to an upper equilibrium point, counteracts the lowering movement between the upper equilibrium point and a lower reversal point of force and assists the lowering movement from the lower point of force reversal.
  • the cabin ceiling part is automatically lowered from the upper rest position to the upper equilibrium point. In the upper equilibrium point of the cabin ceiling part is then held by the restoring element in suspension and prevents further rapid sagging of the cabin ceiling part in the cabin interior. In addition, the cabin ceiling part is automatically lowered from the lower equilibrium point in the lower position and prevents the cabin ceiling part from popping up when reaching the lower position. The handling of the lowerable cabin ceiling part is so much easier and safer.
  • FIGS. 1 to 3 show a first embodiment of a lowerable cabin ceiling.
  • the lowerable cabin ceiling has a ceiling frame 2, a lowerable cabin ceiling part 1 and a lowering mechanism.
  • the lowering mechanism in turn has two subsystems. Each of these subsystems is designed as a pivoting fork frame, which is composed of a base bar 14 and two fork legs 10, 11, 12, 13.
  • the show FIGS. 1 to 3 the cabin ceiling part 1 in an extended position, an intermediate position and a rest position. From the FIG. 3 It can be seen that the lowering mechanism takes up little space in its folded state.
  • FIG. 3 introduced an orthogonal reference system with the directions x, y and z, the also on the in the Figures 1 and 2 as well as in the FIGS. 4 to 16 shown embodiments finds application.
  • the two subsystems each have a pivoting fork frame, consisting of a base rod 14 and two rod-shaped fork legs 10, 11, 12, 13, which are each connected at right angles to the end of the base bar 14.
  • a base bar 14 of a first pivoting fork frame is rotatably mounted on the ceiling frame 2.
  • the free ends of the two rod-shaped fork legs 10, 11 are coupled by means of Drehlinear Inserten with the cabin ceiling part 1.
  • a basic rod of a second pivoting fork frame is rotatably mounted on the cabin ceiling part 1 and the free ends of the two fork legs 12, 13 are coupled by means of Drehlinear Inserten with the ceiling frame 2.
  • the two basic rods 14 are arranged at right angles to each other.
  • the first pivoting fork frame prevents the cabin ceiling part 1 from rotating around the x-axis of the in Figure 3 shown xyz coordinate system and the second pivoting fork frame prevents the cabin ceiling part 1 at a rotation about the y-axis, so that the cabin ceiling part 1 always remains aligned horizontally.
  • the first pivoting fork frame prevents displacement of the cabin ceiling part 1 in the y-direction and the second pivoting fork frame prevents a displacement of the cabin ceiling part 1 in the x-direction. Since the two pivoting fork frame a rotation of the cabin ceiling part 1 order To prevent the z-axis, the kinematic degrees of freedom of the lower cab lower part 1 reduce to a vertical mobility in the z-direction.
