DETAILED DESCRIPTION

(7) FIG. 1 shows an elevator shaft 10 of an elevator system, in which a mounting device 26 is disposed. From elevator shaft 10, only a lower part 12 having a shaft pit 14, a middle part 16, and an upper part 18 including a shaft head 20 are shown. In the lower part 12 of elevator shaft 10, a lowermost door cutout 22 is disposed on a lowermost floor of a building, and in the middle part 16 an upper door cutout 24 is disposed on an upper floor. Door cutouts 22, 24 can be reached via the mentioned floors, and elevator shaft 10 is accessible via door cutouts 22, 24. For this reason, door cutouts 22, 24 are referred to as accessible door cutouts.

(8) Mounting device 26 has a carrier component 28 and a mechatronic installation component 30. Carrier component 28 is designed as a frame, at which mechatronic installation component 30 is mounted. This frame has dimensions that enable to vertically displace carrier component 28 within elevator shaft 10, meaning to travel to different vertical positions at different floors within a building, for example. In the shown example, mechatronic installation component 30 is designed as an industrial robot which, hanging downwards, is attached to the frame of carrier component 28. One arm of industrial robot 30 can be moved relative to carrier component 28 and, for example, be displaced in the direction of a shaft wall 32 of elevator shaft 10.

(9) Carrier component 28 is connected to a displacement component 36 in the shape of a motor-driven cable winch via a steel cable serving as suspension means 34, which is attached at the top of elevator shaft upper part 18 to the ceiling of elevator shaft 10. With the aid of displacement component 36, mounting device 26 can be vertically displaced inside elevator shaft 10 over an entire length of the elevator shaft 10.

(10) Furthermore, mounting device 26 has a fixing component, with the aid of which carrier component 28 can be fixed inside elevator shaft 10 in a lateral direction, meaning in the horizontal direction. The fixing component is made up of two extendable props 38 and an elongated support member 40, support member 40 on the side of door cutouts 22, 24 and extendable props 38 being situated on the opposite side at carrier component 28. By extending props 38, carrier component 28 can be wedged between shaft walls 32 of elevator shaft 10 during a fixing phase.

(11) At the bottom of carrier component 28, a magazine receiving device 42 is pivotably situated in the direction of door cutouts 22, 24. This magazine receiving device 42 serves to receive at least one, in particular two, magazine components not shown in FIG. 1. The magazine components may make mounting means, in particular in the form of rail brackets, also called brackets, and fastening means in the form of screws available to industrial robot 30 for installation on a shaft wall 32.

(12) At support component 28, a control device 44 is disposed, which controls industrial robot 30 and not-shown actuators of extendable props 38.

(13) As shown in FIG. 2, magazine receiving device 42 is designed as two parts, the two parts 45, 47 each being disposed on one side of carrier component 28. Since two parts 45, 47 are constructed identically, only first part 45 will be described. Part 45 of the magazine receiving device 42 has a U-shaped cross-section including a base 46 and side parts 48. Side parts 48 are situated pivotably on two holding arms 50 on a holding rod 52. The holding rod 52 is fixed to carrier component 28 and extends horizontally, so that part 45 of magazine receiving device 42 is pivotally situated in the direction of door cutouts 22, 24 on carrier component 28. Since the second part 47 is also disposed pivotably on carrier component 28 in the direction of the door cutouts 22, 24, this also applies to magazine receiving device 42.

(14) Moreover, a blocking device 54, which has an actuator in the form of an electric motor 56 and two bolts 58 extendable and retractable horizontally from electric motor 56 in the direction of holding arms 50 of two parts 45, 47 of magazine receiving device 42, is disposed on carrier component 28. In a resting position of blocking device 54, two bolts 58 are retracted, so that a pivoting of two parts 45, 47, and thus magazine receiving device 42, is possible. In a blocking position of blocking device 54, two bolts 58 are extended, so that a pivoting of two parts 45, 47, and thus magazine receiving device 42, is blocked. In FIG. 2, the blocking position of blocking device 54 is shown. The electric motor 56 is also controlled by control device 44.

(15) In FIG. 3, the magazine receiving device 42 is shown in a so-called mounting position. Starting from carrier component 28, holding arms 50 are aligned vertically downward. The blocking device is in the blocking position, bolts 58 are thus extended and magazine receiving device 42, for this reason, cannot pivot in the direction of upper door cutout 24. In the mounting position of magazine receiving device 42, industrial robot 30 can remove mounting means from a magazine component 60 disposed on magazine receiving device 42, and carrier component 28 can be displaced in elevator shaft 10.

(16) Between the carrier component 28 and the magazine receiving device 42 or the first part 45 of the magazine receiving device 42, an energy store in the form of a tension spring 62 is disposed in such a manner that a torque acts on magazine receiving device 42 or first part 45 of magazine receiving device 42, which from the mounting position shown in FIG. 3 is aligned in the direction of a loading position of magazine receiving device 42 shown in FIG. 4. Tension spring 62 thus exerts a force on magazine receiving device 42 or first part 45 of magazine receiving device 42, which has a component in the direction of door cutout 24. In an analogous manner, a second tension spring can be disposed between carrier component 28 and the second part of magazine receiving device 42.

(17) Tension spring 62 is designed in such a manner that it can move magazine receiving device 42 having an empty or at least almost empty magazine component 60 into the loading position. Although magazine component 60 is empty in FIG. 3, however, since bolt 58 of blocking device 54 is simultaneously extended, the pivoting of magazine receiving device 42 is thereby blocked, magazine receiving device 42 nevertheless remains in the mounting position.

(18) In FIG. 4, magazine receiving device 42 is shown in a so-called loading position. Starting from carrier component 28, holding arms 50 are pivoted in the direction of upper door cutout 24. The blocking device is in the resting position, bolts 58 are thus retracted so that magazine receiving device 42 could pivot in the direction of upper door cutout 24. In the loading position of magazine receiving device 42, a stocked magazine component 61 can be disposed on magazine receiving device 42 via upper door cutout 24.

(19) To get from the position shown in FIG. 3 of magazine receiving device 42 into the position shown in FIG. 4, the blocking device is first moved into the resting position, thus bolt 58 is retracted. As described, since magazine component 60 in FIG. 3 is empty, the force of tension spring 62 is sufficient to pivot magazine receiving device 42 in the direction of upper door cutout 24. Subsequently, carrier component 28 and thus also magazine receiving device 42 are lowered as far in the elevator shaft until base 46 of magazine receiving device 42 rests on a base 63 of the floor assigned to upper door cutout 24. Two bases 46 and 63 thus are at the same level.

(20) If two bases 46 and 63 are at the same level, first, carrier component 28 is fixed in the elevator shaft. Subsequently, empty magazine component 60 is removed from magazine receiving device 42 by an autonomous mobile robot 64. For this purpose, the autonomous mobile robot 64 couples to magazine component 60 having rollers and pulls it off base 46 of magazine receiving device 42. If more than one empty magazine component is present, the others are removed in the same way.

(21) Subsequently, autonomous mobile robot 64 couples with a stocked magazine component 61. In magazine component 61 having rollers, a plurality of rail brackets 66 and screws 68 are disposed, which are required for the following mounting steps. Mobile autonomous robot 64 pushes stocked magazine component 61 onto base 46 of magazine receiving device 42 and thus disposes it at carrier component 28. If more than one loaded magazine component is present, the others are disposed on carrier component 28 in the same manner. Base 46 of magazine receiving device 42 has a recess, not shown, in which two rollers of magazine component 61 situated on one axis are disposed. In this way, magazine component 61 is secured against rolling away.

(22) The empty magazine component can also be removed by an installer, possibly with the aid of suitable levers or rods, from the magazine receiving device. Likewise, the stocked magazine component can be pushed by an installer onto the base of the magazine receiving device.

(23) Tension spring 62 is configured in such a manner that a stocked magazine receiving device 42, that is to say a magazine receiving device 42 having a fitted magazine component 61, can independently move from the loading position into the mounting position. The force of tension spring 62 is therefore not sufficient to keep stocked magazine receiving device 42 in the loading position. In FIG. 4, however, this is prevented by the fact that base 46 of magazine receiving device 42 rests on base 63 of the floor and, in so doing, the pivoting of magazine receiving device 42 is blocked.

(24) The pivoting of magazine receiving device 42 is made possible only when the fixation of carrier component 28 is released and it is raised in the elevator shaft. This results in that the pivoting is no longer blocked and magazine receiving device 42 is pivoted against the force of tension spring 62 by its weight force into the mounting position.

(25) FIG. 5 shows magazine receiving device 42 after pivoting into the mounting position is completed. This position is identical to the position in FIG. 3. The difference between FIG. 3 and FIG. 5 is only that stocked magazine component 61 instead of empty magazine component 60 is disposed on carrier component 28. Mounting device 26 can now perform further installation steps and install mounting means in the form of rail brackets 66 and screws 68 on the shaft walls.

(26) For the installation of rail brackets 66 in an elevator shaft 10 of an elevator system, first, displacement component 36 is fixed in shaft head 20 and is provided with suspension means 34. Subsequently, mounting device 26 is disposed in elevator shaft 10 and connected via suspension means 34 to displacement component 36.

(27) Subsequently, magazine receiving device 42, as described in connection with FIGS. 3 and 4, is moved into the loading position at lower door cutout 22. After setting the loading position, carrier component 28 in a fixing phase is fixed laterally in elevator shaft 10. For this purpose, props 38 are extended and thus carrier component 28 is wedged in elevator shaft 10. After completion of the fixation phase, two stocked magazine components 61 are disposed on carrier component 28, as described in connection with FIGS. 4 and 5, thus a loading phase is carried out. The magazine components were either stocked outside the elevator shaft 10 in a stocking phase or were delivered already stocked to the building, in which the elevator shaft is located. The stocking phase then took place outside the building.

(28) After completion of the loading phase, props 38 are again retracted and thus the fixation of carrier component 28 is released in the lateral direction. Mounting device 26 can thus carry out a plurality of mounting steps. For this purpose, the mounting device is displaced in a plurality of displacement phases in relation to elevator shaft 10 and is positioned at different heights within elevator shaft 10. After a positioning, in each mounting phase, rail brackets 66 are installed to shaft walls 32 using screws 68 at different heights in elevator shaft 10.

(29) Since the two magazine components cannot accommodate all rail bracket 66 needed for entire elevator shaft 10 and screws 68, empty magazine components have to be replaced with stocked magazine components. In order to be able to execute this task as quickly as possible, the magazine components not always are exchanged via lowermost door cutout 22, but via an accessible door cutout of elevator shaft 10, which is directly adjacent to a position of carrier component 28 in the previous mounting phase.

(30) Since it is already known prior to the installation of rail brackets 66, at which positions in the elevator shaft how many rail brackets are installed using how many screws, it is planned in a planning phase, which takes place in particular before the onset of the installation, at which door cutouts a loading phase will be necessary. On the basis of this planning, stocked magazine components 61 in a supply phase are provided at door cutouts provided for a loading phase. The supply phase can in particular be carried out in one session before the onset of the installation. But it is also possible that the supply phase will be interrupted again and again. It merely has to be ensured that a stocked magazine component 61 is also provided at the time at which a loading phase is to be carried out via a door cutout.

(31) Finally, it should be noted that terms such as “comprising”, “including”, 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.

(32) 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.
