DETAILED DESCRIPTION

(10) According to FIG. 1, an elevator shaft 10 for an elevator system (not shown) has a first bottom door opening 12, with which a first bottom floor 13 is associated. A second floor 15 comprising a second door opening 14, a third floor 17 comprising a third door opening 16, a fourth floor 19 comprising a fourth door opening 18 and a fifth top floor 21 comprising a fifth top door opening 20 are connected from above to said first bottom floor 13.

(11) An installation device 24 (shown in FIG. 1 in a simplified manner merely as a rectangle) is supported against a threshold 22 of the third floor 17 diagonally upward in the elevator shaft 10. The installation device 24 is also supported against a shaft wall 26 that is opposite the third shaft opening 16. By means of a lifting means 28, for example in the form of a cable or a chain, an automated mounting apparatus 30 is suspended from the installation device 24, by means of which mounting apparatus at least partially automated mounting steps can be carried out in the elevator shaft 10. The mounting apparatus 30 can be designed, for example, according to a mounting apparatus described in WO 2017/016783 A1. The mounting apparatus 30 can be displaced vertically in the elevator shaft 10 by means of a displacement apparatus (not shown in FIG. 1) of the installation device 24. The mounting apparatus 30 can thus perform mounting work at the level of the first and second floor 13, 15 when the installation device 24 is in the position in the elevator shaft 10 shown in FIG. 1.

(12) In order for it to be possible to carry out mounting 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 removing the installation device 24 on the third floor 17, the mounting apparatus 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 apparatus 30 can be brought back into the elevator shaft 10 from the second floor 15.

(13) In reality, elevator shafts in which an installation device of this kind and an automated mounting apparatus are used comprise significantly more than 5 floors, for example at least 15 floors. The installation device can also displace the mounting apparatus in particular over more than 2 floors, for example 30 floors or approximately 100 m.

(14) According to FIGS. 2 and 3, the installation device 24 has a first carrier 32, on the first end 34 of which a support element 36 is pivotably arranged. In FIG. 2, the pivot axis extends perpendicularly to the plane of the drawing. The support element 36 has a first flat abutment element 38 which abuts the bottom of a floor when the installation device 24 is in the installation position, and is secured to the bottom by means of screws. The support element 36 also has a second flat abutment element 40 which is arranged perpendicularly to the first abutment element 38 and abuts the shaft wall that forms the threshold together with the bottom of the floor when the installation device 24 is in the installation position, and is secured to said shaft wall by means of screws.

(15) A second carrier 33 is arranged in parallel with and at a distance from the first carrier 32, which second carrier is constructed so as to be identical to the first carrier 32. The distance between the two carriers 32, 33 may be, for example, between 400 mm and 800 mm.

(16) A first cross member 44 is arranged on the second carrier end 42 that is opposite the first carrier end 34, to which cross member a hanging cable (not shown) and a safety line (not shown) for actuating a safety brake of the automated mounting device can be fastened. The first cross member 44 is screwed to both carriers 32, 33 such that it ensures that there is the above-mentioned distance between the carriers 32, 33. The first cross member may also be clamped to the carriers by means of suitable fixtures in the same manner as the components of the installation device mentioned further below.

(17) A holding apparatus 46 is arranged in the region of the first carrier end 34, which apparatus holds a displacement apparatus 48 in the form of an electric winch. The holding apparatus 46 consists of a mainly flat plate made of metal, which is screwed to the carriers 32, 33 and thus also ensures that there is the above-mentioned distance between the carriers 32, 33. In FIG. 2, the holding apparatus 46 is arranged on an upper side 47 of the installation device 24 such that it is arranged on the upper side 47 of the installation device 24 when the installation device 24 is in the installation position. The displacement apparatus 48 is arranged on the holding apparatus 46 and the two carriers 32, 33 in FIG. 2, and is thus supported from above on the holding apparatus 46 and on the carriers 32, 33 in FIG. 2 and thus when the installation device 24 is in the installation position. The holding apparatus could also be designed such that the displacement apparatus is supported exclusively on the holding apparatus. A region 50 of the displacement apparatus 48 that is oriented toward the second carrier end 42 of the first carrier 32 is braced to the first and second carrier 32, 33 by means of a tensioning belt 52.

(18) A deflection roller 54 is arranged approximately centrally between the first carrier end 34 and the second carrier end 42. The deflection roller 54 is mounted in a housing 56 which is screwed to the two carriers 32, 33. The deflection roller 54 is arranged such that it is inserted between the two carriers 32, 33 and deflects a load-bearing means 28 coming from the displacement apparatus 48 such that said means extends vertically downward downstream of the deflection roller 54. The deflection roller 54 is arranged such that the load-bearing means 28 is arranged approximately in the center of the elevator shaft 10 when the installation device 24 is in the installation position.

(19) A second cross member 58 is arranged and screwed to the carriers 32, 33 between the deflection roller 54 and the second carrier end 42. The second cross member 58 has an eyelet 60 to which a cable (not shown) can be fastened. By means of this cable, the installation device can be pivoted into and out of the installation position in a controlled manner.

(20) The displacement apparatus 48 is not shown in FIG. 3 so that two first alignment elements 62 of the holding apparatus 46 can be seen, which elements are designed as openings. The two first alignment elements 62 interact with two second alignment elements 64 of a mounting plate 65 shown in FIGS. 4 and 5, which second alignment elements are designed as extensions. The mounting plate 65 is screwed to the displacement apparatus 48 from below such that it is arranged between the displacement apparatus 48 and the holding apparatus 46 or the carriers 32, 33 when the installation device 24 is in the mounted state. The mounting plate 65 has a mainly T-shaped basic shape and consists of a metal plate that is a few millimeters thick, the second alignment elements 64 having been formed by bending over corresponding parts of the metal plate. The first alignment elements 62 and the second alignment elements 64 are arranged such that the second alignment elements 64 are inserted into the first alignment elements 62 when the mounting plate 65, and thus the displacement apparatus 48, is positioned in a correct mounting position relative to the holding apparatus 46. The insertion may be referred to as an interaction between the alignment elements 62, 64. If said correct mounting position is reached, the holding apparatus 46 can be screwed to the mounting plate 65, and thus to the displacement apparatus 48.

(21) The mounting plate 65, and thus the displacement element 48, also has a guide element 66. The guide element 66 is also designed as an extension and is formed analogously to the second alignment elements 64 by bending over a corresponding part of the metal plate. The guide element 66 is designed and arranged such that it is inserted between the carriers 32, 33 and is supported laterally thereagainst when the displacement apparatus 48, and thus the mounting plate 65, is pushed onto the holding apparatus 46 and the carriers 32, 33. The two carriers 32, 33 thus form a guide 70 of the installation device 24, which cooperates with the guide element 66 when the displacement apparatus 48 is arranged on the installation device 24.

(22) The mounting plate 65, and thus the displacement apparatus 48, also has two sliding elements 72, which are arranged on the two outer ends of the T-shaped mounting plate 65. The sliding elements 72 are bent slightly upward such that they can slide effectively on the two carriers 32, 33 when the displacement apparatus 48 is arranged on the installation device 24.

(23) FIGS. 6, 7 and 8 show how the installation device 24 can be brought into its installation position inside the elevator shaft 10 in a particularly simple and safe manner.

(24) As shown in FIG. 6, a deflection element 74 in the form of a deflection roller is first secured, for example screwed, directly below the threshold 22 of the floor 17 and thus in the region of the threshold 22 of the door opening 16. Subsequently, the installation device 24 is suspended from a top 78 of the door opening 16 by means of two load-bearing elements 76 designed as chain pulleys such that the first carrier end 34 is arranged outside the elevator shaft 10 and the second carrier end 42 is arranged inside the elevator shaft. The two load-bearing elements 76 are secured to two suspension points 75, 77 of the installation device 24. The holding apparatus 46 acts as the first suspension point 75 and the eyelet 60 on the second cross member 58 acts as the second suspension point 77.

(25) A third load-bearing means 80 in the form of a cable is then fastened to the first carrier end 34 and guided around the deflection element 74. By pulling on an end of the third load-bearing element 80 that is opposite the first carrier end 34 in a direction 82 which is directed away from the elevator shaft 10, the installation device 24 is pivoted about the top 78 of the door opening 16. The first carrier end 34 is thus moved toward the elevator shaft 10.

(26) The installation device 24 is pivoted until the support element is arranged in a correct position for being secured to the threshold 22 of the door opening 16. If necessary, the length of one or both load-bearing elements 76 is also varied or adapted accordingly for this purpose.

(27) When the support element has reached the correct position, it is secured to the threshold 22 of the door opening 16 by means of screws. This position is shown in FIG. 7.

(28) After the support element has been secured, the installation device 24 is pivoted into the elevator shaft 10 about the threshold 22 of the door opening 16 until the second carrier end 42 is supported against the shaft wall 26 that is opposite the door opening 16, as a result of which the installation position of the installation device 24 shown in FIG. 8 is reached. Before this pivoting, the load-bearing elements 76, 80 are removed and a cable (not shown) is attached to the eyelet 60 of the installation device 24, by means of which cable the pivoting is carried out in a controlled manner.

(29) After the installation device 24 has reached its installation position, the displacement apparatus 48 is arranged on the installation device 24. For this purpose, the displacement apparatus 48 is first placed on the holding apparatus 46 from above by means of the screwed-on mounting plate 65. The tensioning belt 52 is then loosely guided around the displacement apparatus 48 and the two carriers 32, 33 and the tensioning belt 52 is closed. The displacement apparatus 48 is then pushed into the correct position. If the correct position is reached, the displacement apparatus 48 is screwed to the holding apparatus 46 and the tensioning belt 52 is tightened. The displacement apparatus 48 is thus firmly secured to the installation device 24.

(30) In order for it to be possible to guide the load-bearing means 28 around the deflection roller 54, the entire installation device 24 is pivoted toward the door opening 16 by means of the above-mentioned cable and then brought back into the installation position. The pivoting toward the door opening 16 can be repeated, for example if further parts which have been transported upward by means of the load-bearing means 28 from further down in the elevator shaft 10 are intended to be arranged on the installation device 24.

(31) If the installation device is to be removed from the elevator shaft again and detached from the threshold, this can be done in the reverse order of bringing the installation device into the installation position.

(32) 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 may also be used in combination with other features or steps of other embodiments described above.
