Description

DESCRIPTION OF THE DRAWINGS

[0016] The invention will be explained in more detail below by means of figures.

[0017] FIG. 1 shows an elevator installation comprising a door system;

[0018] FIG. 2 shows the door system in horizontal cross section; and

[0019] FIG. 3 shows a door of the door system.

DETAILED DESCRIPTION

[0020] FIG. 1 shows an elevator installation 2. The elevator installation 2 comprises an elevator shaft 1. The elevator shaft 1 has a plurality of shaft door openings arranged at floors. The elevator installation 2 comprises a plurality of shaft doors 6.1, 6.2, 6.3, wherein a first one of the shaft doors 6.1 is arranged at a first one of the shaft door openings and a second one of the shaft doors 6.2 is arranged at a second one of the shaft door openings. The elevator installation 2 has an elevator car 4 comprising a car door 7.

[0021] The elevator car 4 is movably arranged in the elevator shaft 1. To ensure sufficient safety while the elevator car 4 moves, the elevator car 4 is sufficiently spaced apart from the components, which are fixed in the elevator shaft 1, in particular the shaft doors 6.1, 6.2, 6.3. This distance is identified by a door sill gap S. It is prevented by means of the door sill gap S that components of the elevator car 4, for example the car door 7, touch the components fixed in the elevator shaft 1 or collide with them, respectively, while the elevator car 4 moves.

[0022] FIG. 2 shows a part of the elevator car 4 shown in FIG. 1, which is arranged at a floor, in a horizontal cross section. The car door 7 of the elevator car 4 comprises a first car door leaf 20 and can comprise a further car door leaf 21. The shaft door 6 arranged at the floor comprises a first shaft door leaf 22 and can comprise a further shaft door leaf 23.

[0023] The first car door leaf 20 is mounted at the elevator car 4 by means of a main pivot axis 24, which is preferably arranged vertically. The second car door leaf 21 is mounted at a secondary pivot axis 25 at the first car door leaf 20 in such a manner that the car door 7 is formed as folding door. The main and secondary pivot axis 24, 25 assigned to the car door 7 are preferably arranged in parallel. In a closed position of the car door 7, the at least one car door leaf 20, 21 is substantially arranged along a car door plane 10. This means that at least one car door leaf 20, 21, in the closed position of the car door 7, substantially forms this car door plane 10. The car door plane 10 is preferably arranged vertically in the elevator installation.

[0024] The second car door leaf 21 has a bearing shaft 28. This bearing shaft 28, which can be assigned to the car door 7, can be arranged along an end of the second car door leaf 21 or—as shown in FIG. 2—in the direct vicinity thereof. When the car door 7 is closed, this first end is formed by means of the end of the second car door leaf 21, which is spaced apart from the main pivot axis 24, which can be assigned to the car door 7. The bearing shaft 28, which can be assigned to the car door 7, can be displaced along the car door plane 10 during an opening or closing movement, respectively, of the car door 7.

[0025] The first shaft door leaf 22 is mounted at the floor side, preferably at a component of the shaft door 6, which is fixedly connected to the elevator shaft, by means of a main pivot axis 26. The main pivot axis 26, which can be assigned to the shaft door leaf 22, is preferably arranged in parallel to the main pivot axis 24, which can be assigned to the first car door leaf 20. The second shaft door leaf 23 is mounted at a secondary pivot axis 27 at the first shaft door leaf 22 in such a manner that the shaft door 6 is formed as folding door. In the closed position thereof, the at least one shaft door leaf 22, 23 is arranged along a shaft door plane 12.

[0026] The second shaft door leaf 23 has a bearing shaft 29. This bearing shaft 29, which can be assigned to the shaft door 6, can be arranged along an end of the second shaft door leaf 23 or—as shown in FIG. 2—in the direct vicinity thereof. When the shaft door 6 is closed, this end, which can be assigned to the second shaft door leaf 23, is formed by the end of the second shaft door leaf 23, which is spaced apart from the main pivot axis 26, which can be assigned to the shaft door 6. The bearing shaft 29, which can be assigned to the shaft door 6, can be displaced along the shaft door plane 12 during an opening or closing movement, respectively, of the shaft door 6.

[0027] To guide the second shaft or car door leaf 21, 23, respectively, the shaft or car door 6, 7, respectively, comprises a non-illustrated guide device. A guide shoe can in each case be arranged at the corresponding bearing shaft 28, 29 at and upper and/or lower end of the second shaft or car door leaf 21, 23, respectively. In an exemplary manner, the at least one guide shoe can in each case be guided by a guide groove, which is arranged at the upper and/or lower closure of the car or shaft door opening, respectively, along the car door or shaft door plane 10, 12, respectively.

[0028] The first and second car door leaf 20, 21, in the open position thereof, can form an opening angle a of 5-15 degrees, preferably 10 degrees. The first and the second shaft door leaf 22, 23, in the open position thereof, can form an opening angle b of 5-15 degrees, preferably 10 degrees. The door sill gap S is arranged between the car door plane 10 and the shaft door plane 12, wherein, vertically to the shaft or car door plane 10, 12, this door sill gap S can have a smaller dimension than the car door plane 10 is spaced apart from the shaft door plane 12.

[0029] According to FIG. 2, the first shaft door leaf 22 and the first car door leaf 20, in the open position thereof, are arranged so as to be stacked directly next to each other. The second shaft door leaf 23 and the second car door leaf 21, in the open position thereof, are likewise arranged so as to be stacked directly next to each other. A straight line formed in the horizontal cross section, which extends through both secondary pivot axes 25, 27, is thus arranged substantially vertically to the car door 10 or to the shaft door plane 12, respectively.

[0030] FIG. 3 shows a car door 7, which is arranged at a car door opening, of a door system in the closed position thereof. The car door opening has a door opening width B. In an exemplary manner, the car door 7 comprises a plurality of car door leaves 20, 21, 30, 31. The car door leaves 20, 21, 30, 31, in the closed position thereof, cover the car door opening substantially completely. This means that a first one of these car door leaves 20, 21, 30, 31 covers or closes, respectively, at least a part of the car door opening.

[0031] In the closed position thereof, a first one of the car door leaves 20, which is pivotably mounted at a main pivot axis 24, has a horizontally oriented width BK1 in the direction of the door opening width B. Spaced apart from the main pivot axis 24, a second one of the car door leaves 21 can be pivotably mounted at the first car door leaf 20 at a secondary pivot axis 25, wherein the first and the second car door leaf 20, 21 form a fold of a folding door. In the closed position thereof, the second car door leaf 21 has a horizontally oriented width BK2 in the direction of the door opening width B. Preferably, the widths BK1 and BK2 of the door leaves 20, 21 are largely identical. The car door leaves 30, 31 and the pivot axes 34, 35 correspond to the car door leaves 20, 21 and pivot axes 24, 25 respectively in mirror image.

[0032] FIG. 3 and the description provided thereto also apply to a shaft door of the door system.

[0033] In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
