DETAILED DESCRIPTION

[0048] According to FIG. 1, an elevator system 10 has a hoistway 12 for a three-story building, which in the present exemplary embodiment is composed of a first basic module 14, a second basic module 16 and a top module 18. The hoistway 12 can comprise further second basic modules 16 depending on the number of floors. The shaft modules 14, 16, 18 are pre-produced in a factory and provided with elevator components. Subsequently, they are brought to the construction site and put on top of one another. The hoistway modules 14, 16, 18 all have a predominantly cuboid base shape. In particular, they are mainly made of wood. Of course, other materials such as concrete are also conceivable.

[0049] FIG. 2 shows how the top module 18 is placed on the second basic module 16 from above by means of a crane 20. The second basic module 16 was previously placed in the same way onto the first basic module 14. The basic module 14 stands on a foundation (not shown) of the hoistway 12. The basic modules 14, 16 form a hoistway which is open at the top and has not yet been completed and which is closed off at the top by placing the top module 18 on it.

[0050] Moreover, the elevator installation 10 according to FIG. 1 has a car 22 which can be moved vertically in the hoistway 12 along guide rails (not shown). For this purpose, the elevator installation 10 has lifting gear 24, the first end 26 of which is fixed in the top module 18. It then extends downward and around the car 22 and is guided via a drive machine 28 arranged in the top module 18 opposite the first end 26 of the lifting gear 24. From there, it runs through a suspension of a counterweight 30 to its second end 32, which is fixed in the region of the drive machine 28. The drive machine 28 can move the lifting gear 24 and thus the car 22 in the hoistway 12.

[0051] According to FIG. 3, the second base module 16, i.e., a hoistway module for forming a hoistway 12 of an elevator installation 10, has a first side wall 34 with a door opening 36 that opens downward. The first side wall 34 is mainly shaped as an upside-down U. In the illustration in FIG. 3, a second side wall 38 on the left side and a third side wall 40 on the right side each adjoin the first side wall 34 at an angle of 90, i.e., not 180.

[0052] A hoistway door 42 is arranged in the door opening 36. The first base module 14 and the top module 18 can be constructed in the same way as the second base module 16 described in detail below, at least with respect to the hoistway door. The hoistway door 42 is fixed, among other things, by means of an upper door mount module 44. The upper door mount module 44 has three metal tongues 48 by means of which an upper, horizontally extending part of a door frame 50, a so-called door transom 52, is screwed to a crossbeam 54 of the first side wall 34. Since the metal tongues 48 in FIG. 3 are arranged behind the door transom or jamb 52 and the crossbeam 54, they are shown by dashed lines.

[0053] The hoistway door 42 has a horizontally extending door sill 64, which closes off the hoistway door 42 at the bottom. It extends over almost the entire width of the door opening 36 of the first side wall 34 and is designed as a flat rail, in particular made of metal, elongated in a main direction of extension 65 of the door sill 64.

[0054] The door sill 64 is fixed or fastened by a final door sill mount 46 to the second side wall 38 and to the third side wall 40 and thus to the hoistway module 16. The door sill mount 46 has a first wall bracket 56 having two legs arranged perpendicularly to one another. A vertically extending leg (57 in FIGS. 4 and 5) of the first wall bracket 56 is screwed to the second side wall 38.

[0055] A second wall bracket 59 having the same design as the first wall bracket 56 is screwed to the third side wall 40 at the same height as the first wall bracket 56. A door sill support 62 of the final door sill mount 46, which in particular mainly consists of a metal profile, extends between the second side wall 38 and the third side wall 40. The door sill support 62 thus also extends in the main direction of extension 65 of the door sill 64. The door sill support 62 rests on the horizontally extending legs (61 in FIGS. 4 and 5) at its two ends and is thus supported on the two wall brackets 56, 59. The door sill 64 rests on the door sill support 62 and, during operation of the elevator installation 10, serves, among other things, to guide movable door segments of the hoistway door 42 (not visible in FIG. 3).

[0056] The above-mentioned movable door segments are arranged in FIG. 3 and thus behind a fixed door segment 60 in the transport state of the second base module 16 and are secured against movement by means of a transport lock 66 in the form of a Z-shaped safety catch 68. The safety catch 68 is screwed at its first end to the second side wall 38 and has a crosspiece 70 at its second end, which rests against the door segments in such a way that they cannot be moved away from the second side wall 38. The movable door segments are thus secured in their open position. Instead of the one Z-shaped safety catch, on each side of the door segments a Z-shaped safety catch or a U-shaped safety catch can be used.

[0057] The hoistway door 42 and thus also the door sill 64 must usually be aligned or adjusted after the base module 16 has been placed on top of the base module 14. The final door sill mount 46 offers different options, not all of which necessarily have to be implemented. What all options have in common is that the wall brackets do not have to be removed from the side walls for the purposes of alignment or adjustment, meaning that the final door sill mount does not have to be undone or removed. It is sufficient to loosen connections, for example screw connections between the wall brackets and the side walls, the wall brackets and the door sill support or the door sill support and the door sill, and tighten them again after the alignment or adjustment process.

[0058] A first way of aligning or adjusting the hoistway door 42 and thus the door sill 64 consists in changing the position of the wall brackets 56, 59 on the side walls 38, 40. As an example, according to FIG. 4, the vertical leg 57 of the first wall bracket 56, which rests on and is screwed to the second side wall 38, has an elongated hole 63. In the example shown in FIG. 4, the elongated hole 63 is vertical. It is also possible to provide a horizontal elongated hole. After loosening a screw 67 which projects through the elongated hole 63 and is screwed into the second side wall 38, the position of the first wall bracket 56 relative to the second side wall 38 can be changed within the frame defined by the elongated hole 63. The same applies to the second wall bracket 59.

[0059] Thus, the first wall bracket 56 and the second wall bracket 59 are designed and fastened to the second side wall 38 and the third side wall 40, respectively, in such a way that their position on the second side wall 38 and the third side wall 40, respectively, can be changed together with the door sill support 62. By changing the position of the first wall bracket 56 and/or the second wall bracket 59 as mentioned, the door sill 64 can be aligned or adjusted.

[0060] A second way of aligning or adjusting the hoistway door 42 and thus the door sill 64 consists in that the first wall bracket 56, the second wall bracket 59 and the door sill support 62 are designed and connected to one another in such a way that the position of the door sill support 62 relative to the first wall bracket 56 fastened to the second side wall 38 and relative to the second wall bracket 59 fastened to the third side wall 40 can be changed. As an example, according to FIG. 5, the door sill support 62 has a first T-slot 69 which is open downward in the direction of the horizontally extending leg 61 of the first wall bracket 56 and extends transversely to the main direction of extension 65 of the door sill support 62. A head of a screw 71 is arranged in the first T-slot 69, the position of which in the first T-slot 69 can be changed in the direction of extension of the first T-slot 69 and thus transversely to the main direction of extension 65 of the door sill support 62. The first wall bracket 56 has a through-hole 73 in its horizontally extending leg 61, which is aligned with the first T-slot 69 of the door sill support 62. The above-mentioned screw 71 projects through the through-hole 73 and, together with the nut 72 screwed onto the screw 71, clamps the door sill support 62 against the first wall bracket 56. The same applies to the connection of the door sill support 62 to the second wall bracket 59. The door sill 64 is arranged on the door sill support 62.

[0061] It is also possible that the first T-slot extends in the main direction of extension of the door sill support.

[0062] The through-hole 73 of the first wall bracket 56 has a diameter that is larger than the diameter of the screw 71 projecting through the through-hole 73. This allows the position of the door sill support 62 relative to the wall bracket 56 to also be changed transversely to the direction of extension of the first T-slot 69 and thus in the main direction of extension 65 of the door sill support 62. In addition, the first T-slot 69 is of such a width that the head of the screw 71 arranged in the first T-slot 69 can also be moved transversely to the direction of extension of the first T-slot 69 relative to the door sill support 62. The same applies to the connection of the door sill support to the second wall bracket.

[0063] A third way of aligning or adjusting the hoistway door 42 and thus the door sill 64 consists in that the door sill support 62 and the door sill 64 are designed and connected to one another in such a way that the position of the door sill 64 relative to the door sill support 62 can be changed. As an example, according to FIG. 6, the door sill 64 has a second T-slot 75 which is open in the direction of the door sill support 62 and runs in the main direction of extension 65 of the door sill support 62. The main direction of extension 65 of the door sill support 62 runs perpendicularly to the plane of the illustration in FIG. 6. A head of a screw 77 is arranged in the second T-slot 75, the position of which in the second T-slot 75 can be changed in the direction of extension of the second T-slot 75 and thus in the main direction of extension 65 of the door sill support 62 and the door sill 64. The door sill support 62 has a through-hole 79 which is aligned with the second T-slot 75 of the door sill 64. This allows the screw 77 to project through the through-hole 79 and, together with the nut 78 screwed onto the screw 77, to clamp the door sill 64 against the door sill holder 62.

[0064] It is also possible that the second T-slot runs transversely to the main direction of extension of the door sill support.

[0065] The through-hole 79 of the door sill support 62 has a diameter in width that is larger than the diameter of the screw 77 projecting through the through-hole 79. This allows the position of the door sill 64 relative to the door sill support 62 to also be changed transversely to the direction of extension of the second T-slot 75. In addition, the second T-slot 75 is of such a width that the head of the screw 77 arranged in the second T-slot 75 can also be moved relative to the door sill 64 transversely to the direction of extension of the second T-slot 75.

[0066] According to FIG. 6, the door sill 64 is fixed to the door sill support 62 by a plurality of connections distributed over the width of the hoistway door 42.

[0067] In addition, the hoistway door 42 can be adjusted by changing its position relative to the metal tongues 48 of the upper door mount module 44.
