Description

DESCRIPTION OF THE DRAWINGS

[0021] The invention is explained in greater detail below with reference to drawings. In the drawings:

[0022] FIG. 1: shows an elevator system with a guide rail arranged in the elevator shaft;

[0023] FIG. 2: shows a shaft door and an installation bracket arranged on a floor;

[0024] FIG. 3: shows an installation bracket, and

[0025] FIG. 4: shows an installation bracket fixed to the floor.

DETAILED DESCRIPTION

[0026] FIG. 1 shows an elevator system 1. The elevator system 1 comprises an elevator shaft 4. The elevator shaft 4 is bounded at its lower end by a shaft floor 4.1. The elevator shaft 4 is bounded laterally by a door-side shaft wall 6.1. Further shaft walls 6.2, 6.3 bounding the elevator shaft 4 can be present. The door-side shaft wall 6.1 has a plurality of shaft door openings 20.1, 20.2, 20.3, 20.4 or wall openings arranged one above the other by means of which the elevator shaft 4 is connected to floors 10.1, 10.2, 10.3, 10.4 located one above the other.

[0027] A guide rail 8, on which an elevator car 5 can be guided, is arranged along the orientation of the elevator shaft 4. This guide rail 8 is usually formed by a plurality of guide rail segments (not shown) arranged one above the other. In addition, further guide rails can be arranged in the elevator shaft 4 in order to be able to guide the elevator car 5 and, if applicable, also a counterweight (not shown) which is movable in the opposite direction to the elevator car 5.

[0028] An installation bracket 30 fixed in the elevator system 1 is shown in the region of the lowest of the floors 10.1. The installation bracket 30 makes it possible to fix the guide rail 8, in particular a lowermost of the guide rail segments belonging to the guide rail 8. The elevator system 1 can comprise further such installation brackets, wherein each of these installation brackets can be fixed separately to another of the floors 10.2, 10.3, 10.4 located above the lowest floor 10.1. To relieve the load on the installation bracket 30, the guide rail 8 or the guide rail segment fixed to the installation bracket 30 can be set on the shaft floor 4.1, in particular supported by this shaft floor 4.1.

[0029] FIG. 2 shows a shaft door opening 20 arranged on one of these floors 10. A shaft door 42 is arranged at this shaft door opening 20. The floor 10 comprises a concrete surface 10 and can comprise a walk-on surface 10 that can be walked on during conventional use of the floor 10, wherein the walk-on surface 10 can be formed for example by application of a screed.

[0030] The installation bracket 30 for fixing at least one guide rail 8 or at least one guide rail segment is accordingly fixed on the floor 10 by means of at least one floor fixing section 31, preferably before application of the exemplary screed to the concrete surface 10. A door sill 40 can be arranged above the at least one floor fixing section 31 so that with the walk-on surface 10 the door sill 40 forms a substantially flat area. In addition, the door sill 40 can be integrated in the walk-on surface 10 in such a way that the walk-on surface 10 does not form a shoulder or a groove or the like.

[0031] It can also be seen from FIG. 2 that the floor fixing section 31, formed for example by a crossmember 35, is closed by a stop denoted by 35.1. This stop 35.1 abuts the door-side shaft wall 6.1.

[0032] Substantial components of the shaft door 42 are arranged in the vertical alignment of the floor 10. This means that these substantial components of the shaft door 42 are arranged outside the cross-sectional area of the elevator shaft 4. The substantial components of the shaft door 42 comprise, for example, the door sill 40, a door leaf 44 and a guide rail 46 for guiding the door leaf 44. The shaft door 42 can moreover comprise further door leaves 44, wherein the shaft door 42 can be designed to close centrally or telescopically.

[0033] In addition, the shaft door 42 can comprise coupling elements 47 for mechanical coupling to a coupling unit arranged on the elevator car. The elevator car can accordingly comprise a car door having a door drive motor. This door drive motor is provided, for example, for a synchronous opening/closing of the shaft door coupled to the car door and, if applicable, also for unlocking the car door and/or the shaft door. With respect to the shaft door 42, the coupling unit accordingly fulfills the purpose of establishing an operative connection between the door drive motor and the shaft door 42. Such coupling elements 47 accordingly project into the cross-sectional area of the elevator shaft 4.

[0034] FIG. 3 shows such an installation bracket 30. The installation bracket 30 comprises a crossmember 35 and two side members 36.1, 36.2, preferably extending at right angles to the crossmember 35. A guide rail 8 is fastened or can be fastened in each case to the ends of these side members 36.1, 36.2.

[0035] The installation bracket 30 comprises two floor fixing sections 31.1, 31.2 which are arranged along the crossmember 35 for directly fixing the crossmember 35 to a floor. By way of example, the installation bracket 30 can be fixed with screws 32.1, 32.2 or similar fastening elements that are to be anchored in the floor.

[0036] The fixing sections 31.1, 31.2 are in each case formed by a through-opening 33.1, 33.2. By means of such a through-opening 33.1, 33.2, the installation bracket 30 can be fixed to the floor in an adjustable manner. Accordingly, a washer can be used for adjustable fixation. Adjustment points 37.1, 37.2 enable adjustability with respect to further installation brackets 30 arranged in the elevator shaft by means of exemplary plumb lines or comparable alignment elements such as laser beams suitable for aligning the installation bracket 30.

[0037] The installation bracket 30 can be adjustably fixed to the floor in the horizontal direction. This can be achieved for example by the floor fixing sections 31.1, 31.2 being designed as elongated holes or an oversized dimension in comparison with the corresponding dimension of the fastening elements 32.1, 32.2 used for fixing.

[0038] FIG. 4 shows an installation bracket 30 fixed to a floor. The installation bracket 30 is fixed directly to the concrete floor 10 by means of its crossmember 35. The crossmember 35 can have a rib or stop 35.1 which can be arranged at the end of the floor that bounds the elevator shaft 4. The rib 35.1 forms a stop towards the door-side shaft wall 6.1 and can close the crossmember towards the elevator shaft. The rib extends in a horizontal direction between the side members 36.1 and 36.2. When the installation bracket 30 is properly fixed to the floor, this rib 35.1 preferably projects vertically downward so that a minimum distance of the guide rail, which can be fixed on the installation bracket 30, from the floor can accordingly be maintained by means of this rib 35.1.

[0039] 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.
