DETAILED DESCRIPTION

[0024] FIG. 1 shows an elevator shaft 2 of an elevator installation 1 during a phase of installing the elevator installation 1, wherein the elevator shaft 2 is illustrated in dashed lines. The elevator shaft 2 has at least one wall 4.1, 4.2, 4.3, 4.4 and a shaft floor 7. The elevator shaft 2 is bounded by the shaft floor 7 and the at least one wall 4.1, 4.2, 4.3, 4.4. In addition, the elevator shaft can be bounded by a shaft ceiling 6. The elevator shaft 2 has a plurality of shaft door openings. Only a lowermost one of the shaft door openings 8a and an uppermost one of the shaft door openings 8b are illustrated in correspondence with the arrangement thereof in the elevator shaft 2.

[0025] A device 20 for aligning components 10 of the elevator installation 1 is arranged in this elevator shaft 2. The device 20 comprises a positioning frame 22 and at least one guide line 28. The guide line 28 serves for the usual vertical alignment of the component 10 of the elevator installation 1, for example of a guide rail. The positioning frame 22 is fixed with respect to the wall 4.2 having the shaft door openings 8a, 8b. The positioning frame 22 comprises, for example, positioning aids 24.1, 24.2, 24.3, 24.4, 25.1, 25.2. A first pair 24.1, 24.2 and a second pair 24.3, 24.4 of the illustrating positioning aids 24.1, 24.2, 24.3, 24.4, 25.1, 25.2 are provided for alignment of guide rails for guidance of an elevator car of the elevator installation. A third pair 25.1, 25.2 of the illustrated positioning aids 24.1, 24.2, 24.3, 24.4, 25.1, 25.2 is provided for alignment of guide rails for guidance of a counterweight of the elevator installation 1. The at least one guide line 28 is fixed to the shaft ceiling 6 by way of fastening means 32.1, 32.2, 32.3, 32.4. Each of these guide lines 28 is aligned in the elevator shaft 2 by means of the positioning aids 24.1, 24.2, 24.3, 24.4, 25.1, 25.2. In the illustrated example the positioning aids 24.1, 24.2, 24.3, 24.4, 25.1, 25.2 are formed by bores formed in the positioning frame 22, wherein at least one guide line 28 is associated with an individual one of these bores and is guided therethrough. The guide lines 28 each have a plumb-bob 30. This plumb-bob 30 enables perpendicular orientation of the guide line 28 in the elevator shaft 2.

[0026] FIG. 2 shows two regions of an elevator shaft 2. The illustrated lower region shows a shaft pit, which is arranged above a shaft floor 7, of the elevator shaft 2. The elevator shaft 2 is additionally bounded by walls 4.1, 4.2, 4.3 along the elevator shaft 2. A lowermost shaft door opening 8a is arranged above the shaft floor 7 in a first one of the walls 4.2.

[0027] The components 10 which need alignment by means of a device 20 for alignment of these components 10 in the elevator shaft are already installed in the lower region of the elevator installation. The device 20 comprising a positioning frame 22 and at least one guide line 28 (28.1, 28.2) is partly shown above these already installed components 10 in the illustrated upper region. An alternative variant (not illustrated) consists of arranging the device 20 in the immediate vicinity of the shaft floor 7 so as to align the entire guide rail 10 by means of the guide line 28.

[0028] The positioning frame 22 is fastened in the elevator shaft 2. The positioning frame 22 is fixed with respect to the wall 4.2, which has the shaft door opening 8a, of the elevator shaft 2. That also means that the positioning frame 22 is fixed with respect to the wall 4.1 illustrated on the left and also the wall 4.3 illustrated on the right of the elevator shaft 2.

[0029] The detail, which is illustrated on the right-hand side in FIG. 2, of the device 20 comprising the positioning frame 22 is constructed in accordance with the known prior art. Accordingly, a first guide line 28.1 of the device 20 is fixed by means of a fastening 31 to the positioning frame 22 itself. By virtue of the fixing of the first guide line 28.1 directly to the positioning frame 22 an increased capability of loading of the positioning frame 22 is necessary. Accordingly, the positioning frame 22 is of a stronger construction at the fastening means 31, which is recognizable in FIG. 2 by a thickness, which is increased by comparison with the positioning frame 22 illustrated on the left-hand side, of the positioning frame 22 illustrated on the right-hand side.

[0030] The detail, which is illustrated on the left-hand side in FIG. 2, of the device 20 comprising the positioning frame 22 is constructed in accordance with a form of embodiment of the present invention. A second one of the guide lines 28.2 is fixed to the wall 4.1 by way of a fastening means 32. The fastening means 32 comprises a base 41, which is fastened directly to the wall 4.1, and an arm 40 pivotable at the base 41. The pivotable arm 40 is pivotably mounted on the base 41 in such a way that the second guide line 28.2, which is fastened to the pivotable arm 40, can be aligned with respect to the positioning frame 22. This means that the second guide line 28.2 is only slightly deflected in the immediate vicinity of the positioning aid 24.2 of the positioning frame 22. The second guide line 28.2 is fastened to the pivotable arm 40 at the point 29.

[0031] The section B, which is provided for alignment of the component 10, of the second guide line 28.2 is arranged above the positioning frame 22 as indicated by the arrow. Accordingly, not only the first 28.1, but also the second guide line 28.2 can be aligned above the positioning frame 22 by means of a further positioning frame (not illustrated) of the device 20.

[0032] FIG. 3 shows the fastening means 32, which is illustrated in FIG. 2, of the second guide line 28.2 from a view (A-A) from above in the direction of the shaft pit of the elevator shaft. The arm 40 is pivotable about the axis S by means of the pivot movement P. The guide line 28.2 is not vertically guided from the point 29, for example, to the positioning aid 24.2. From the positioning aid 24.2 the guide line 28.2 runs substantially vertically upwardly along the section B illustrated in FIG. 2.

[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.
