DETAILED DESCRIPTION

[0044] According to FIG. 1, an elevator shaft 10 for an elevator system (not shown) has a first, bottom door opening 12, to which a first, bottom floor 13 is assigned. This first, bottom floor 13 is followed at the top by a second floor 15 having a second door opening 14, a third floor 17 having a third door opening 16, a fourth floor 19 having a fourth door opening 18 and a fifth, top floor 21 having a fifth, top door opening 20.

[0045] At a threshold 22 of the third floor 17, an installation device 24, which is shown in a very simplified form in FIG. 1, is supported diagonally upward in the elevator shaft 10. The installation device 24 is also supported on a shaft wall 26 which is opposite the third shaft opening 16. The installation device 24 has a displacement device 48 in the form of an electric winch. An automated mounting device 30 is suspended from the displacement device 48 and thus from the installation device 24 via a suspension means 28 of the displacement device 48, for example in the form of a cable or a chain, by means of which mounting device assembly steps can be carried out in the elevator shaft 10 in an at least semi-automated manner. The mounting device 30 can be designed, for example, in accordance with a mounting device described in WO 2017/016783 A1. The mounting device 30 can be vertically displaced in the elevator shaft 10 by means of the displacement device 48 and the suspension means 28. In the position of the installation device 24 shown in FIG. 1, the mounting device 30 can carry out assembly work in the elevator shaft 10 at the height of the first and second floors 13, 15. The mounting device 30 is used when installing an elevator system in the elevator shaft 10 and can therefore be referred to as installation material.

[0046] In order to be able to carry out assembly work further up in the elevator shaft 10, the installation device 24 can be brought into the installation position on the fifth floor 21. Before the installation device 24 is removed from the third floor 17, the mounting device 30 can be temporarily stored on the second floor 15. When the installation device 24 has been brought back into the installation position on the fifth floor 21, the mounting device 30 can be brought back into the elevator shaft 10 from the second floor 15.

[0047] In reality, elevator shafts in which an installation device of this kind and an automated mounting device are used have significantly more than 5 floors, for example at least 15 floors. The installation device can move the mounting device in particular over more than 2 floors, for example 30 floors or approximately 100 m.

[0048] According to FIGS. 2 and 3, the installation device 24 has an elongate carrier 32 which extends in a carrier direction 31, at the first end 34 of which carrier a support element 36 is pivotably arranged. The pivot axis in FIG. 2 extends perpendicularly to the representation plane. The support element 36 has a first, flat contact element 38 which, in the installation position of the installation device 24, rests against the ground of a floor 17 and is fixed to the ground with screws. The support element 36 also has a second, flat contact element 40, which is arranged perpendicularly to the first contact element 38 and, in the installation position of the installation device 24, rests against the shaft wall 23, which forms the threshold 22 with the ground of the floor 17, and is fixed to this wall with screws.

[0049] The carrier 32 is supported at a second carrier end 42 opposite the first carrier end 34 on the shaft wall 26 of the elevator shaft 10. A first holder 44 is arranged at the second carrier end 42, to which holder a suspension cable (not shown) and a safety tether (not shown) for triggering a safety brake of the automated mounting device can be attached. The holder 44 is screwed to the carrier 32. It can also be clamped to the carrier using suitable brackets.

[0050] An adjustable support device 52 is arranged approximately centrally on the carrier 32 by means of two U-shaped holders 50 which encompass the carrier 32. The adjustable support device 52 has two longitudinal beams 56 which extend in the carrier direction 31 and are spaced apart from one another in a transverse direction 54 which extends perpendicularly to the carrier direction 31. The longitudinal beams 56 are firmly connected to the carrier 32 via the two holders 50 such that the adjustable support device 52 is supported on the carrier 32.

[0051] The adjustable support device 52 bears a receiving device 46 for receiving a displacement device (not shown in FIGS. 2 and 3). The receiving device 46 has a rectangular frame 58 made of metal profiles, which frame forms a support surface 60 of the receiving device 46. The frame 58 is open on the inside, such that the suspension means of the displacement device, which is also not shown in FIGS. 2 and 3, can extend downward unhindered. The receiving device 46 has a first side 62 which is oriented in the direction of the first carrier end 34 and a second side 64 which is opposite the first side in the carrier direction 31 and is therefore oriented in the direction of the second carrier end 42. Connection elements 66a, 66b, 66c, 66d which are arranged next to one another in the transverse direction 54 are arranged on the first side 62 of the receiving device 46. Connection elements 66e, 66f, 66g, 66h which are arranged next to one another in the transverse direction 54 are arranged on the second side 64 of the receiving device 46. The connection elements 66a, 66b, 66c, 66d, 66e, 66f, 66g, 66h are designed as tabs made of metal which extend downward away from the receiving device 46 and each have a through-opening.

[0052] The receiving device 46 is connected to the longitudinal beams 56 of the support device 52 via the connection elements 66f and 66g on the second side 64 of the receiving device 46. The connection is established by a bolt 68, which protrudes through a through-opening (not shown) in the longitudinal beam 56 and through the mentioned opening of the connection elements 66f and 66g and is secured. The receiving device 46 can thus be pivoted about the bolt 68 relative to the longitudinal beams 56 and thus relative to the carrier 32.

[0053] Via the connection elements 66a and 66d on the first side 62 of the receiving device 46, the receiving device 46 is connected via a multi-part arm 70 to a transverse beam 71 of the support device 52, which transverse beam extends in the transverse direction 54 and is fixed to the longitudinal beams 56. For this purpose, the transverse beam 71 has two tabs 72 with which the connection to the arms 70 is established. The connection between the arms 70 and the connection elements 66a and 66d is established by a bolt 74 which protrudes into the arms 70 and through the mentioned opening of the connection elements 66a and 66d through a through-opening (not shown) and is secured. The receiving device 46 can thus be pivoted about the bolt 74 relative to the arms 70. The connection between the arms 70 and the tabs 72 of the transverse beam 71 of the support device 52 is established by a bolt 76 which protrudes into the arms 70 and the tabs 72 of the transverse beam 71 of the support device 52 through a through-opening (not shown) and is secured. The arms 70 can thus be pivoted about the bolts 76 relative to the transverse beams 71 of the support device 52 and thus relative to the carrier 32.

[0054] The arms 70 consist of two arm parts that can be displaced relative to one another. A first arm part 78 which is connected to one of the connection elements 66a, 66b can be pushed into a second arm part 80 which is connected to one of the tabs 72 of the longitudinal beams 56 of the support device 52 and can be secured in different positions with a bolt 79. The arm parts 78, 80 are designed as metal profiles, a rectangular inner contour of the second arm part 80 being adjusted to an outer contour of the first arm part 78 such that the contour can receive the first arm part 78. The first arm part 78 has a plurality of through-holes indicated by dots, each of which can be brought into alignment with a through-hole of the second arm part 80, which through-hole is also indicated as a dot. The bolt 79 is inserted through the aligned recesses in the first arm part 78 and in the second arm part 80 and secured, whereby the two arm parts 78, 80 are fixed relative to one another.

[0055] By telescoping the two arm parts 78, 80 into one another or pulling them apart, the length of the arm 70 can be changed and the receiving device 46 can thus be pivoted about the bolt 68 relative to the longitudinal beams 46 and thus relative to the carrier 32. By fixing the two arm parts 78, 80 relative to one another with the bolt 79, a fixed position of the receiving device U.S. Pat. No. 8,646,224 B2 relative to the longitudinal beams 46 and thus relative to the carrier 32 can be set. An angle ? between a support plane 82, in which the support surface 60 of the receiving device 46 extends, and the carrier direction 31 of the carrier 32 can thus be changed. The mentioned angle ? is in particular adjusted such that the support plane 82 extends horizontally or at least approximately horizontally.

[0056] The receiving device 46 also has two side skirts 84 for securing a displacement device which is received by the receiving device 46 between the side skirts 84. The side skirts 84 extend upward perpendicularly from the support plane 82. The side skirts 84 have recesses 86 via which the displacement device can be secured by means of screws. The two side skirts can be designed to be the same or different. In particular, the side skirts can differ in the height thereof, i.e. in the extension thereof in the vertical upward direction in the mounted state.

[0057] The connection elements 66a, 66b, 66c, 66d, 66e, 66f, 66g, 66h are arranged in the transverse direction 54 such that the first side 62 of the receiving device 46 having the connection elements 66a, 66b, 66c, 66d can be oriented, as shown in FIG. 3, in the direction of the first carrier end 34 or, as shown in FIG. 5, in the direction of the second carrier end 42. Since the connection elements 66a, 66b, 66c, 66d and 66e, 66f, 66g, 66h are arranged offset along the first side 62 and the second side 64, respectively, in the two mentioned positions of the receiving device 46 in the transverse direction 54, different positions of the receiving device 46 relative to the carrier 32 result.

[0058] A second holder 88 is arranged between the second side 64 of the receiving device 46 and the second carrier end 42 and is screwed to the carrier 32. The second holder 88 has an eyelet 90 to which a cable (not shown) can be attached. This cable can be used to pivot the installation device into and out of the installation position in a controlled manner.

[0059] In FIGS. 4 and 5, the installation device 24 is shown in an elevator shaft 10 which is less deep in comparison to FIG. 2. The carrier direction 31 is therefore inclined upward to a greater extent in comparison to FIG. 2. So that the support plane 82 nevertheless extends horizontally, the first arm parts 78 of the arms 70 are pulled further out of the second arm parts 80 in comparison to FIG. 2. This leads to a larger angle ? between the support plane 82 and the carrier direction 31 in comparison to FIG. 2.

[0060] So that the suspension means of a displacement device which is received by the receiving device 46 also extends approximately in the center in the less deep elevator shaft 10, the combination of the support device 52 and the receiving device 46 was moved further in the direction of the second carrier end 42 on the carrier 32 by means of the holder 50 in comparison to FIG. 2. For this purpose, the mentioned combination was first removed from the carrier 32 and then remounted on the carrier 32 in the appropriate position. The combination of the support device 52 and the receiving device 46 thus forms an assembly 92 which can be removed from the carrier 32 and mounted on the carrier 32 at different positions in the carrier direction 31.

[0061] The assembly consisting of the receiving device and the adjustable support device in the carrier direction can also be arranged on the carrier such that it can be displaced relative to the carrier. In this way, the displacement device can already be arranged on the receiving device when the mentioned assembly is still in the vicinity of the first carrier end. The mentioned assembly can then be brought or pulled into the intended position thereof with the displacement device, for example with a chain hoist. The described displacement of the mentioned assembly relative to the carrier in the carrier direction is implemented in particular by designing the mentioned U-shaped holders and the carrier such that they are displaceable relative to one another.

[0062] As can be seen in FIG. 5, the carrier device 46 is arranged in a different position in the transverse direction 54 relative to the carrier 32 in comparison to FIG. 2. The first side 62 of the receiving device 46 is oriented in the direction of the second carrier end 42 and the second side 64 of the receiving device 46 is oriented in the direction of the first carrier end 34. The connection elements 66h, 66e of the second side 64 are thus connected to the arms 70 and the connection elements 66b, 66c are connected to the transverse beam 71 of the support device 52.

[0063] Finally, it should be noted that terms such as comprising, having, etc. do not preclude other elements or steps and terms such as a or an do not preclude a plurality. Furthermore, it should be noted that features or steps that have been described with reference to one of the above embodiments can also be used in combination with other features or steps of other embodiments described above.

[0064] 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.
