DETAILED DESCRIPTION

[0032] FIG. 1 shows a schematic representation of an elevator system 2 comprising an elevator shaft 4. The elevator system 2 comprises an elevator car 6 and can comprise a counterweight 8, with the elevator car 6 being arranged such that it can be moved along the elevator shaft 4. The elevator car 6 and the counterweight 8 are connected by means of a suspension element 10. The suspension element 10 is guided in a shaft head of the elevator shaft 4 via deflection rollers 12. For example, one of these deflection rollers 12 can be designed as a drive roller of a drive unit of the elevator system 2.

[0033] If the counterweight 8 is present, the elevator car 6 and the counterweight 8 are therefore arranged to be movable in opposite directions within the elevator shaft 4. Guide rails 14, 16 for guiding the elevator car 6 or the counterweight 8 in the elevator shaft 4 are arranged along the movement path of the elevator car 6 or the counterweight 8. The elevator system 2 usually comprises two guide rails 14 for guiding the elevator car 6 or two guide rails 16 for guiding the counterweight 8.

[0034] Each of these guide rails 14, 16 usually comprises a plurality of short guide rail segments which, when fixed in a row on a shaft wall 18 of the elevator system 2, form the corresponding guide rail 14, 16. The guide rails 14, 16 extend along the movement path of the elevator car 6 and the counterweight 8. Therefore, the guide rails 14, 16 usually extend substantially along the entire extent of the elevator shaft 4. Each of the guide rails 14, 16 or each of their guide rail segments is fixed to the shaft wall 18 by means of a large number of rail brackets 20.

[0035] FIG. 2 shows a component, in particular such a rail bracket 20, of the elevator system 2 in cross section when it is fixed to the shaft wall 18. The guide rail 14, 16 can be fixed to this rail bracket 20 by means of fixing clips 19 provided for this purpose. The rail bracket 20 usually comprises at least two contact surfaces 34 for fixing the rail bracket 20 to the shaft wall 18. Each of these contact surfaces 34 is arranged on a rail bracket foot 41.

[0036] For example, such a rail bracket 20 can be fixed to the shaft wall 18 manually or by machine. In the case of machine fixation, the use of assembly devices is suitable. Such an assembly device is disclosed by way of example in WO2019063356. Such assembly devices prepare the elevator shaft 18 for the installation of further constituents of the elevator system 2.

[0037] FIG. 3 shows a detail A which was indicated in FIG. 2. A portion of the rail bracket 20 which has one of the at least one contact surfaces 34 and is fixed to the shaft wall 18 is shown. A self-adhesive element 30 is arranged between the contact surface 34 and the shaft wall 18. The self-adhesive element 30 has a dimension denoted as thickness D perpendicular to the surface of the shaft wall 18. By means of this thickness D of the self-adhesive element 30 which is used to prefix the rail bracket 20, a strength of the adhesive layer can be predetermined, which strength of the adhesive layer also corresponds to the dimension D.

[0038] The rail bracket foot 41 of the rail bracket 20 can have at least one through-hole 40, 42. The through-hole 40, 42 penetrates the rail bracket foot 41 and thus the contact surface 34 in such a way that the adhesive can be introduced into a space between the contact surface 34 and a fixing region of the shaft wall 18 when the rail bracket 20 is prefixed, or in such a way that it is possible for this space to be monitored. By means of this monitoring, when this space is filled with adhesive, it is possible to see whether or when enough adhesive has been introduced into the space.

[0039] The rail bracket foot 41 preferably has a first through-hole 40 which is adapted for applying the adhesive to the contact surface 34. The through-hole 40 is in particular adapted for introducing the adhesive into the space between the contact surface 34 and the fixing region of the shaft wall 18 by means of an adhesive pump.

[0040] Additionally or alternatively, the rail bracket foot 41 can have at least one through-hole 42 for visually monitoring the space between the contact surface 34 and the fixing region of the shaft wall 18 and/or for ventilating this space when the adhesive layer is applied. Accordingly, the air can be displaced into the interior of the elevator shaft 4 by applying the adhesive layer.

[0041] FIGS. 4 to 6 each show an embodiment according to a section B-B indicated in FIG. 3. The contact surface 34 of the rail bracket foot 41 is essentially shown as a constituent of the rail bracket 20. The contact surface 34 has a first part 50 and a second part 52. The first part 50 is provided for applying the self-adhesive element 30, 30′ which is provided for the prefixing. For example, the self-adhesive element 30, 30′ can be fixed to the fixing region of the shaft wall 18 and the rail bracket 20 can be pressed against the fixing region for prefixing, so that prefixing of the self-adhesive element 30, 30′ can take place. As an alternative to this, the self-adhesive element 30, 30′ can be fixed to the rail bracket 20 prior to being prefixed to the shaft wall 18.

[0042] The second part 52 is provided for applying the adhesive layer which is provided for curing and thus for the final fixing of the rail bracket 20 to the shaft wall 18. The first part 50 of the contact surface 34 is preferably formed in an edge region R of the contact surface 34. The second part 52 of the contact surface 34 is preferably formed inside the first part 50 of the contact surface 34.

[0043] The self-adhesive element 30 shown in FIG. 4 is formed continuously in the first part 50 formed along the edge region R. The self-adhesive element 30 formed continuously in the edge region can be porous in order to ventilate the space formed between the contact surface 34 and the fixing region of the shaft wall.

[0044] According to the embodiment shown in FIG. 4, the rail bracket foot 41 has at least one through-hole 42 for ventilating the space between the contact surface 34 and the fixing region of the shaft wall as well as the porous self-adhesive element 30 described above. It is also possible, for example, for such a self-adhesive element 30 having porosity to be used as an alternative to the through-hole 42 provided for ventilating the space between the contact surface 34 and the fixing region of the shaft wall 18.

[0045] The self-adhesive element 30′ shown in FIGS. 5 and 6 has breaks 44. Such breaks 44 in the self-adhesive element 30′ can be formed alternatively or in addition to the at least one through-hole 42 for ventilating the space between the contact surface 34 and the fixing region of the shaft wall 18 or the self-adhesive element 30′ having porosity.

[0046] According to FIG. 5, the breaks 44 can be distributed along the edge region R. According to the embodiment shown in FIG. 6, the contact surface 34 has an upper region 64 and a lower region 62. The upper region 64 is delimited directly on one side by an upper edge 63 and the lower region 62 is delimited directly on one side by a lower edge 61.

[0047] This lower edge 61 faces from the contact surface 34 in the direction of the bottom of the elevator shaft 4, and the upper edge 63 faces from the contact surface 34 in the opposite direction, preferably toward a shaft head of the elevator shaft 4. The through-hole 40 for applying the adhesive layer is arranged in the upper region 64 of the contact surface 34 so that filling the first part 52 with adhesive results in the adhesive flowing from the upper region 64 into the lower region 62 according to force of gravity. The through-hole 40 is preferably arranged largely centrally between the lateral boundaries of the first part 52 of the contact surface 34.

[0048] The breaks 44 shown in FIG. 6 are preferably arranged at the corners of the contact surface 34 or of the edge region R. This results in the largest possible distance between the breaks 44 for ventilating the space between the contact surface 34 and the fixing region of the shaft wall 18.

[0049] Correspondingly, if the component has previously been prefixed to the shaft wall 18, adhesive flows through the breaks 44 only when the space between the contact surface 34 and the fixing region of the shaft wall is largely filled with adhesive. Thus, if the adhesive flows out of the at least one break, it can be used as a criterion for stopping the application of the adhesive.

[0050] 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.
