Description

Elevator part holder and method for fixing an elevator part holder

The invention relates to an elevator part holder with the features of claim 1 and a method for fixing an elevator part holder with the features of claim 12.

US 2004/216963 A1 describes a method and a device for fastening a guide rail of an elevator installation at a so-called rail angle. The rail angle must be fastened to a shaft wall of an elevator shaft of the elevator system before the guide rail is fastened. The method and the device serve to enable a floating mounting of the guide rail with respect to the rail angle and thus with respect to the shaft wall. The device consists of a large number of individual components, which must be mounted in a fixed order. Among other things, it has a so-called ground support, which has an upper strip element and a lower strip element. The lower strip element has a slot which tapers slightly at both ends and thus forms so-called nub openings. When mounting the device, a projecting through the slot sleeve of a so-called side bracket is rotated by 90 ° and thus set a lateral bias on the guide rail. The sleeve has a knob on its underside, which can engage in the nub opening of said slot and so against a

Twist can be secured. Due to its construction, the device for attaching a guide rail can not be attached directly to the shaft wall of the elevator shaft.

WO 90/15009 AI describes an elevator part holder in the form of a

Rail bracket lower part, which is for fixing to a shaft wall of a

Elevator system is provided. At the rail bracket lower part can

Rail bracket shell are attached to which then a guide rail for a car of the elevator is attached. The lower rail part has two

Recesses in the form of elongated holes can protrude through these two fasteners in the form of screws that are mounted in the shaft wall. The screws may have a head, which the rail bracket lower against the Shaft wall presses. It is also possible that the screw is designed as a bolt on which a nut is screwed, which then presses the lower rail part against the shaft wall. Both when screwing a screw with a head, as well as when mounting and tightening a nut, it is necessary that

Hold the lower part of the bar and secure it against falling down. An installer who wants to fix the lower rail part to the shaft wall, therefore, requires two hands, so he can not fix the lower rail part with one hand on the shaft wall. If the assembly of the lower rail part is automated, for example by a mechatronic robot having a robot

Installation component to be executed, in addition to a manipulator for screwing the screw into the shaft wall or the tightening of the nut another manipulator for the simultaneous holding the rail bracket base is necessary.

In contrast, it is in particular the object of the invention, an elevator part holder, which can be easily and in particular one hand fixed to a shaft wall and to propose a method for fixing an elevator part holder, which can be easily and in particular one-handed. According to the invention, these objects are achieved with an elevator part holder with the features of claim 1 and a method with the features of claim 12.

The elevator part holder according to the invention is for fixing with a

Fastening provided on a shaft wall of an elevator system. The fixation provided for fastening element has a head and a shaft, wherein the head has a larger diameter than the shaft. Of the

Elevator part holder has a recess which has an insertion area and a fixation area. The insertion region of the recess is designed such that said fastening element can be introduced into the recess such that the head and at least part of the shaft of the fastening element are arranged on different sides of the recess. The head of the fastener can thus be guided in the insertion through the recess. The recess has, in particular, a shape deviating from a circular shape.

The elevator part holder is in particular provided directly on a shaft wall to be fixed. In this context, a direct fixation is to be understood as meaning that an intermediate part is not first mounted on the shaft wall and then the elevator part holder is fastened to the intermediate part, that is to say fixed to the shaft wall via the intermediate part. The elevator part holder is fixed for example by means of one or more screws or bolts on the shaft wall.

In addition, the fixation area is designed so that the head of the

Fastener can not be passed through the recess. Thus, the fixing element can initially be incompletely inserted into a mounting hole of the shaft wall for fixing the elevator part holder. Subsequently, the elevator part holder can be positioned opposite the shaft wall such that the head of the fastening element is arranged in the insertion region of the recess with respect to the recess on a side of the elevator part holder lying opposite the shaft wall. For this purpose, the screw head can be guided through the insertion region of the recess or an edge of the recess in the insertion region has an interruption and the elevator part holder can be moved along the shaft wall so that the head of the fastener occupies said position.

In a next step, the elevator part holder can be positioned by displacement relative to the shaft wall so that the head of the fastening element in the fixing region of the recess with respect to the recess on one of

Shaft wall opposite side of the elevator part holder is arranged. Since, as stated above, the head of the fastening element in the fixation area can not be guided through the recess, the elevator part holder can no longer be in the position thus achieved without an active and conscious displacement relative to the

Shaft wall to be removed from the shaft wall.

In a final step, the fastener can continue in the

Mounting hole are introduced in the shaft wall, at least until the head of the fastener comes to the elevator part holder to the plant.

Each of these steps can be performed by a fitter with one hand and thus also by a mechatronic installation component with only one manipulator. In contrast, according to the assembly of a rail bracket lower part WO 90/15009 AI two hands or in an automated assembly, for example, of a robot having mechatronic installation component, in addition to a manipulator for screwing the screw into the shaft wall or the tightening of the nut another manipulator for the simultaneous holding the rail bracket lower part necessary.

The elevator part holder is designed in particular as a rail lower part, to which a rail bracket upper part can be attached, to which then a guide rail for a car of the elevator is attached. But the elevator part holder can also for the support of other components, such as a guide rail of a

Counterweight be provided in a hoistway. The held with the elevator part holder component of a lift system can directly or as described under

Use of an intermediate part to be connected to the elevator part holder. An elevator part holder is to be understood here as a holder which can in particular be fixed directly to a shaft wall of an elevator installation and to which other components of the elevator installation can be fastened and thus also fixed to the shaft wall.

The elevator part holder is designed in particular in one piece. So it consists of only a single component and in particular of a single material. This allows a particularly simple and thus cost-effective construction of the elevator part holder.

The elevator part holder is made for example of a 2 to 8 mm thick sheet metal, which is brought by bending in the desired shape. The outer contour and said recess can be achieved, for example, prior to bending by punching.

The fastening element can be designed, for example, as a so-called screw anchor or screw plug, which can be screwed directly and thus without prior insertion of a dowel in a mounting hole. The fastening element may have a washer which is connected captively to the fastening element, in particular formed directly on the head. The fastener is not part of the elevator part holder according to the invention. The elevator part holder may, in particular, have two or more of the recesses described above, which in particular are each made the same. But it is also possible that the elevator part holder next to one or two of the recesses described additional circular recesses or slots has, through which as described in connection with WO 90/15009 AI, a

Fastener can be performed.

In an embodiment of the invention, the elevator part holder has a fastening region for fastening an elevator part. The attachment region is arranged such that it encloses an angle not equal to 180 ° with a bearing part containing the recess. This is a particularly simple attachment of an elevator part on

Elevator part holder possible. The elevator part holder can also have more than one system part, in particular two system parts and more than one mounting area.

The one or more plan especially executed system components are in the mounted state of the elevator part holder on the shaft wall. As a result of the described arrangement of the fastening region, it projects therefrom away from the shaft wall and thus makes it possible to fasten an elevator part, for example a railing upper part. The one or more plant parts are arranged in a plant level. The particular plan executed mounting area is mainly arranged in a mounting plane. The mounting area and thus the mounting plane include in particular an angle between 45 ° and 135 °, in particular 90 ° with the plant part and thus with the plant level. The mounting area in the assembled state can be mainly horizontal, as well as mainly vertical.

In an embodiment of the invention, the attachment region has a hole, which allows a particularly simple attachment of an elevator part to the elevator part holder. The hole is designed, for example, as a through hole with or without a thread or a blind hole, in particular with a thread. In the case of a non-threaded embodiment, the hole is designed in particular as a slot.

The elevator part holder is designed in particular as a rail bracket lower part.

In an embodiment of the invention, an edge of the recess in the insertion a Interruption on. The interruption is designed so that the shank of the fastener can be guided through the recess, so that after a partial introduction of the fastener into the shaft wall of the

Elevator part holder can be moved along the shaft wall so that the shank of the fastener is passed through the interruption and so the head of the fastener and the shaft wall are arranged on different sides of the recess of the elevator part holder. This will be a very simple one

Sliding the elevator part holder allows for the fastener.

In an embodiment of the invention, the recess has a closed edge and the recess has in the insertion over a width which is greater than a width of the recess in the fixation region. The elevator part holder thus has no open edge in the region of the recess, so that the elevator part holder is designed to be particularly rigid. In this context, a width is the distance between two diametrically opposite points on the edge of the

Recess understood. For example, is the edge in the lead-in and in

Fixing performed as a circular arc section, the width of the diameter of the respective circular arc. The edges may also have a shape deviating from a circular arc. The widths are chosen so that in the insertion of the head of the provided for fixing to the shaft wall fastener can be guided through the recess, but this is not possible in the fixation area.

In an embodiment of the invention, in a fixing position of the elevator part holder, the fixing area is arranged above the lead-in area, the term "above" being related to the geodetic height The fixing position of the elevator part holder means the position in which the elevator part holder is mounted on the shaft wall. Due to the above-mentioned arrangement of the fixation area above the introduction area, gravity prevents the

Attach fastener without applying a force from the outside of the fixation in the insertion and thus the elevator part holder can be solved by the fastener. It is thus ensured that the elevator part holder is secured after placing on the one or more fastener on the shaft wall so that it can not fall down without external influence. this makes possible a particularly secure mounting of the elevator part holder on the shaft wall and in particular allows a safe picking up a tool, in particular a screwdriver.

In an embodiment of the invention, a connecting line between the

Insertion and fixation a kink between 70 ° and 110 °, in particular 90 °. In this context, the connecting line is to be understood as the line along which the shaft of the fastening element is guided with respect to the recess from the insertion region into the fixing region, wherein the

Connecting line perpendicular to the direction of displacement on both sides has an equal distance from the edge of the recess. Starting from the introduction area, the connecting line in the fixing position of the elevator part holder initially runs mainly vertically from bottom to top and then to the side. Due to the mentioned kink inaccuracies in introducing the

Fixing element can be compensated in the shaft wall. such

Inaccuracies may arise, for example, when introducing a

Fixing hole is not possible because of a reinforcement in the shaft wall at the intended location.

The connecting line can also have no kink. In the fixing position of the elevator part holder, it then proceeds, starting from the introduction region, in particular mainly vertically or slightly inclined upwards.

In an embodiment of the invention, the connecting line to a first branch and a second branch, which enclose an angle between 160 ° and 180 °, in particular 180 °. Thus, the above inaccuracies when introducing the fastener into the shaft wall can be compensated particularly well.

In an embodiment of the invention, the edge of the recess between

Introductory area and fixation area a first and a second

Connecting portion and in the fixation region on a first circular arc portion, wherein the first circular arc portion extends in the fixation region, in particular over an angular range between 170 ° and 185 °, in particular over 180 °. This is in the fixation area as large a bearing surface of the head of the Fastening element on elevator part holder allows. This advantageously leads to a particularly secure fixing of the elevator part holder to the shaft wall and to a particularly low surface pressure on the elevator part holder. In this case, a diameter of the first circular arc is in particular only slightly, for example 1 to 2 mm, larger than the diameter of the shaft of the fastening element provided for fixing to the shaft wall. Thus, the above bearing surface of the head of the fastener becomes maximum. The two connecting sections can in particular be arranged parallel to one another and parallel to the mentioned

Connecting line run. In particular, they then have a spacing which corresponds to the diameter of the first circular arc section. If the connecting line has a kink, the connecting sections have a corresponding kink. If the connecting line has a first and a second branch, the recess has in particular a third circular arc section, which is designed in accordance with the first circular arc section. In this case, the recess has, in particular, a third and fourth connecting section, which extend in particular parallel to the second branch of the connecting line. The mentioned

However, connection sections do not have to run parallel to the connection line. It is also possible, for example, for a distance of the connecting sections in the direction of the first and / or third circular arc section to be reduced, that is to say the distance

Connecting portion conically narrows until it reaches a distance corresponding to the diameter of the first or third circular arc section.

In an embodiment of the invention, the edge of the recess in the insertion on a second arc section, which extends in particular over an angular range of more than 180 °, for example, between 280 ° and 320 °, in particular over 300 °. Thus, the head of the fastener in the insertion can be easily guided through the recess. In addition, the recess can thus be made easily and inexpensively.

The above object is also achieved by a method for fixing a

Elevator part holder with a recess, which has an insertion and a fixation area, solved to a shaft wall of an elevator installation, which has at least the following successive steps:

- Incomplete introduction of at least one fastener in a Attachment hole in the shaft wall, wherein the fastener has a head and a shaft and the head has a larger diameter than the shaft,

Positioning the elevator part holder with respect to the shaft wall, so that the head of the fastening element is arranged in the introduction region of the recess with respect to the recess on a side of the elevator part holder lying opposite the shaft wall,

Positioning of the elevator part holder with respect to the shaft wall, so that the head of the fastening element is arranged in the fixing region of the recess with respect to the recess on one side of the elevator part holder opposite the shaft wall and

- Further introduction of the fastener in the mounting hole in the shaft wall, at least until the head of the fastener on

Elevator part holder comes to the plant.

The elevator part holder is designed in particular according to the elevator part holders described above and below.

The fastener, for example in the form of a screw anchor can be screwed in particular with a screwdriver in the mounting hole in the shaft wall and thus introduced. During incomplete insertion of the fastener, the fastener is inserted only so far that between the head of the

Fastening element and the shaft wall is still so sufficient distance that the elevator part holder can be moved between the head and shaft wall.

For the subsequent positioning of the elevator part holder, the insertion region of the recess has in particular, for example, a diameter which is greater than the diameter of the head of the fastening element or the insertion region has an edge with an interruption. Thus, the elevator part holder can either be positioned so that the head of the fastener is guided in the insertion through the recess or the elevator part holder is moved along the shaft wall, that the shank of the fastener is guided by the interruption of the edge of the recess in the insertion. During subsequent positioning, the elevator part holder is displaced in particular along the shaft wall until the head of the fastening element in the

Fixing area is located. Since the head of the fastening element can not be guided through the recess in the fixing area, the elevator part holder can no longer be removed from the shaft wall in the position achieved with it without an active and conscious displacement relative to the shaft wall.

The final further introduction of the fastener at least until the head of the fastener on the elevator part holder comes to rest, takes place in particular again by means of a screwdriver. The head of the fastener does not have to rest directly on the elevator part holder, it can also be applied indirectly. For this purpose, for example, a washer can be arranged between the head and elevator part holder.

Each of these steps can be performed by a fitter with one hand and thus also by a mechatronic installation component with only one manipulator.

In addition to the above steps, before and after, as well as between the mentioned steps, further steps can be performed.

In an embodiment of the invention, said method steps are performed by a mechatronic installation component.

In particular, the mechatronic installation component can also introduce at least one fastening hole into the shaft wall, in particular drill it, before the said steps.

A mechatronic installation component is to be understood as meaning a component which has interacting mechanical, electronic and information technology elements or modules.

For example, the installation component may have suitable mechanics, in order, for example, to be able to handle tools within an assembly step. The Tools can be used by the mechanics, for example, suitable for a

Mounting position are brought and / or be performed during an assembly step suitable. Alternatively, the installation component itself may have a suitable mechanism that forms a tool.

Electronic elements or modules of the mechatronic installation component can serve, for example, mechanical elements or modules of the

Installation component suitable to control or control. Such

electronic elements or modules can thus serve, for example, as a control for the installation component.

Furthermore, the installation component may have information technology elements or modules with which, for example, it can be deduced to which position a tool is brought and / or how the tool is to be operated and / or guided there during an assembly step.

An interaction between the mechanical, electronic and

Information technology elements or modules should take place in such a way that, as part of the installation process, at least one assembly step can be performed semi-automatically or fully automatically by the mounting device.

The mechatronic installation component has in particular an industrial robot.

An industrial robot can be understood as a universal, generally programmable machine for handling, assembling and / or machining workpieces and components. Such robots are designed for use in an industrial environment and have previously been used, for example, in the industrial production of complex goods in large numbers, for example in automobile production.

Usually, an industrial robot has a so-called manipulator, a so-called effector and a controller. The manipulator may, for example, be a robot arm pivotable about one or more axes and / or displaceable along one or more directions. The effector may, for example, be Tool, a gripper or the like. The controller may serve to suitably control the manipulator and / or the effector, that is, for example, suitable to relocate and / or lead.

Often, industrial robots are also equipped with various sensors that enable them to identify information, for example, about their environment, working conditions, components to be processed or the like. For example, sensors, forces, pressures, accelerations, temperatures, etc. can be detected in order to subsequently evaluate them appropriately.

After initial programming, an industrial robot is typically able to perform a semi-automatic or fully automatic, ie largely autonomous, workflow. An execution of the workflow can be varied, for example, depending on sensor information within certain limits. Furthermore, a controller of an industrial robot may optionally be self-learning.

An industrial robot may thus be capable of performing various assembly steps as part of an installation operation in a single installation due to a way in which its components are mechanically and / or electrically configured, and a way in which these components can be controlled by the control of the industrial robot

To perform elevator shaft or adapt to different circumstances during such an assembly step.

In this context, advantageous properties can already be provided in large parts of finished industrial robots, as they are already in use in other fields of technology, and may need only special ones

Be adapted conditions during installation operations in elevator shafts elevator installations. To the industrial robot, for example, within the

To bring elevator shaft to a desired position, this is attached to a carrier component, wherein the carrier component together with the

Industrial robot and optionally other installation components can be moved to a desired position within the hoistway.

As an alternative to the design as an industrial robot, the mechatronic Installation component also be configured in other ways. Conceivable, inter alia, especially for the stated application in a (semi) automated elevator installation constructed mechatronic machines in which, for example, special drills, screwdrivers, feeding components, etc. are used. For example, linearly displaceable drilling tools, screwdriving tools and the like could be used here.

Further advantages, features and details of the invention will become apparent from the following description of exemplary embodiments and with reference to the drawings, in which the same or functionally identical elements are provided with identical reference numerals.

According to FIG. 1, an elevator part holder 10 in the form of a rail bracket lower part has a first system part 11, which rests on the shaft wall when fixed with a fastening element on a shaft wall of an elevator installation. The elevator part holder 10 also has a second system part 12, which is connected to the first system part 11 via a connecting part 13. The connecting part 13 does not have two in FIG. 1 shown oblong holes, by means of which a connection to a rail bracket upper part, not shown, can be produced. The connecting part 13 has a lower portion 14, which runs parallel to the system parts 11 and 12 and thus also bears against the shaft wall, and an upper portion 15 in the form of a mounting region, which is fixed in the shaft wall state, ie in the illustrated fixation position protrudes vertically away from the shaft wall. The upper portion 15 of the connecting part 13 has in the view shown in the direction of the shaft wall mainly an inverted U-shape, wherein the legs are connected to the system parts 11, 12.

The plan executed system parts 11, 12 are arranged or aligned in a plant level, which runs in the assembled state of the elevator part holder 10 along the shaft wall. The upper portion 15 in the form of

Mounting region is arranged or aligned in a mounting plane which is perpendicular to the contact plane and thus me an angle α of 90 ° includes (see Fig. 3).

As shown in Fig. 3, the upper portion 15 in the form of the mounting portion on two juxtaposed holes 40, 41, which as slots and

Through holes are made without thread. Through the holes 40, 41 fasteners, such as screws out and an elevator part, in particular a rail bracket shell are strengthened.

The elevator part holder 10 is made in one piece from a metal sheet, in particular by punching and bending.

The two system parts 11 and 12 are basically the same structure, which is why only the first system part 11 is described. The first plant part 11 has in the illustrated plan view a mainly rectangular basic shape and has a

Recess 16 with an insertion region 17 and a fixing region 18, wherein in the illustrated fixation position of the fixing region 18 above the

Insertion area 17 is arranged. On the shape of the recess 16 is in

Connection with the Fig. 6a received in more detail. The insertion region 17 of the recess 16 is designed so that a head 19 of a provided for fixing the elevator part holder 10 and shown in FIG. 2 fastener 20 in the form of a screw anchor through the

Recess 16 can be performed in the insertion area 17. The fastening element 20 is thus selected so that a maximum diameter Dl of the head 19 of the

Fastener 20 is smaller than a width D2 of the insertion portion 17 of the recess 16 (see Fig. 6a). The fastening element 20 is also chosen such that the head 19 of the fastening element 20 in the fixing region 18 can not be guided through the recess 16.

The fastening element 20 shown in FIG. 2 has, in addition to the head 19, a mainly cylindrical shaft 21 with a thread (not shown). The shaft 21 has a diameter D3 which is smaller than that

Diameter Dl of the head 19 of the fastener 20. To the head 19, a washer 22 is firmly formed, which forms the above-mentioned maximum diameter Dl of the head 19. The fastener 20 is intended to be screwed into a mounting hole in the shaft wall without the use of a dowel. But it is also possible that a dowel is used and / or that the washer is not formed on the head. The maximum diameter of the head should be understood in this case as the larger diameter of the head and washer.

In FIGS. 3, 4 and 5, three successive mounting positions of the elevator part holder 10 during fixation on a shaft wall are shown. Before the

Elevator part holder 10 can be brought into the first mounting position shown in FIG. 3, two mounting holes are introduced into the shaft wall by means of a drill. The arrangement of the two mounting holes corresponds to the arrangement of the fixing regions 18 of the recesses 16 of the two system parts 11 and 12. After the introduction of the mounting holes is ever a

Fastener 20 incompletely screwed into the mounting holes and thus introduced. A remaining distance between the head 19 of the fastener 20 and the shaft wall is greater than a thickness of the plant parts 11, 12th

Subsequently, the elevator part holder 10 is in the first shown in FIG Mounting position brought. For this purpose, the elevator part holder 10 is positioned relative to the shaft wall, that in each case the head 19 of the two fasteners 20 in the insertion region 17 with respect to the recess 16 on one of the shaft wall opposite side of the system parts 11, 12 of the elevator part holder 10 is arranged. For this purpose, the head 19 of the fastening element 20 is guided in the insertion region 17 through the recess 16 and the elevator part holder 10 brought to bear against the shaft wall.

In order to bring the elevator part holder 10 from the first mounting position according to FIG. 3 into the second mounting position according to FIG. 4, the elevator part holder 10 is pushed down along the shaft wall so that the shaft 21 of the fastening elements 20 is guided within the recess 16 to the fixing area 18 becomes. Thus, in each case the head 19 of the fastening element 20 in the fixing region 18 with respect to the recess 16 on one of the shaft wall opposite side of the system parts 11, 12 of the elevator part holder 10 of the elevator part holder 10 is arranged. Since the maximum diameter D1 of the head 19 of the fastening element 20 is greater than a width D4 in the form of the diameter of the first circular arc section 24 of the fixing region 18, the head 19 of the fastening element 20 can not be guided through the recess 16 in the fixing region 18 of the recess 16. Thus, the elevator part holder 10 is at least secured in the second mounting position so that it can not solve by itself from the shaft wall and thus fall down.

In order to achieve the third mounting position of the elevator part holder 10 shown in FIG. 5, the fastener 20 is at least as far further screwed and thus introduced until the head 19 and the integrally formed on the head 19 Washer 22 of the fastener 20 on the elevator part holder 10 for Plant comes and thus the elevator part holder 10 is firmly fixed to the shaft wall.

The steps described may be performed by a fitter by hand or by a mechatronic installation component. Mixed forms are also possible, ie some steps are performed by a fitter and some steps by a mechatronic installation component. The execution of the steps with a mechatronic installation component will be discussed in more detail below. In Fig. 6a, the recess 16 of the in Figs. 1, 3, 4 and 5 is shown

Elevator part holder 10 shown in more detail. The recess 16 has a

Insertion region 17 and a fixation region 18 arranged in the illustrated fixation position above the insertion region 17. The recess 16 has a closed edge 23, which has a first circular arc section 24 in the

Fixing portion 18, a second circular arc portion 25 in the insertion region 17 and two parallel connecting portions 26 and 27, wherein the two connecting portions 26, 27, the two arc sections 24, 25 connect. The recess 16 thus has, like all the corresponding recesses described below, a form deviating from a circular shape. The first circular arc section 24 in the fixation region 18 extends over 180 °, the second circular arc section 25 extends around the insertion region 17 over 300 °. A width D2 of the

Insertion area 17 is determined by the diameter of the second circular arc portion 25. The fastener 20 is particularly chosen so that a

Diameter D3 of the shaft 21 (see Fig. 2) is only minimally smaller than a width D4 in the form of the diameter of the first circular arc portion 24 of the fixing portion 18. This results in a so-called connecting line 28, ie the line along the shaft 21 of the fastener 20 with respect to the recess 16 of

Inserting portion 17 is guided in the fixing region 18, wherein the shaft 21 and thus the connecting line 28 perpendicular to the direction of displacement on both sides an equal distance from the edge 23 of the recess 16, as a connecting line between the center M2 of the second circular arc portion 25 in the insertion region 17 and Center point M4 of the first circular arc portion 24 in the fixing area 18. In the illustrated fixing position of the elevator part holder 10 runs

Connecting line 28 vertically from bottom to top.

In the following, various embodiments of recess are described, which sometimes differ only slightly from each other. It is therefore mainly on the differences between the recesses with each other. The same or similar parts are provided with a reference number increased by 100 in each case.

The recess 116 according to FIG. 6b has an edge 123 which is identical to the edge 23 of the recess 16 from FIG. 6a. The recess 116 differs from the recess 16 in that the connecting line 128 is inclined by 45 ° to the left. The inclination can also be to the right and be more or less than 45 °, for example 10 ° to 80 °.

The recess 216 according to FIG. 6c differs from the recess 16 from FIG. 6a in that the connecting line 228 has a bend through 90 ° to the left and thus over a first branch 229. The recess 216 between insertion region 217 and fixation region 218 has the same width. But it is also possible that the

Recess in the region of the first branch 229 has a smaller width. This can be compensated for inaccuracies in the wells particularly well. This applies to all recesses which have a kink in the connecting line.

The recess 316 according to FIG. 6d differs from the recess 216 from FIG. 6c in that the connecting line 328 has a bend through 90 ° to the left and a bend by 90 ° to the right and thus a first branch 329 to the left and a second branch 330 to the right. The recess 316 thus has a first fixing area 318a and a second fixing area 318b.

The recess 416 according to FIG. 7a has, in contrast to the recesses 16, 116, 216 and 317, no closed but an open edge 423. The edge 423 thus has an interruption 431, which is designed so that the shaft 21 of the fastening element 20 can be guided through the interruption 431. Thus, the elevator part holder can be moved along the shaft wall, that the shaft 21 of the fastener 20 is guided through the interruption 431 that the head 19 of the fastener 20 is disposed on one side of the recess 416 opposite the shaft wall. From the design of the

Apart from insertion region 417, the recess 416 is basically the same as the recess 16 according to FIG. 6a.

The recesses 516 according to FIGS. 7b, 616 according to FIGS. 7c and 716 according to FIG. 7d have lead-in areas 517, 617, 717 corresponding to the lead-in area 417 according to FIG. 7a, otherwise they are analogous to the recesses 116, 216 and 316 according to FIG. 6b, 6c and 6d executed. The recess 816 according to FIG. 8 a has a significantly wider interruption 831 in comparison to the recess 416 according to FIG. 7 a. The edge 823 tapers from the interruption 831 in the direction of the first circular arc section 824 and directly adjoins the first circular arc section 824.

The recess 916 according to FIG. 8b differs from the recess 816 of FIG. 8a in that the edge 923 has two parallel sections before reaching the first circular arc section 924.

The recesses 1016 and 1116 according to FIGS. 8c and 8d have interruptions 1031 and 1131 corresponding to the interruption 831 according to FIG. 8a and two parallel sections corresponding to FIG. 8b in the fixing area, otherwise they are analogous to the recesses 616 and 716 according to FIG 7c and 7d

In Fig. 9 is arranged in a hoistway 51 of an elevator 52

Mounting device 53 shown by means of which the above-described

Elevator part holder can be fixed to a shaft wall 54, for example in the form of lower rail members. The mounting device 53 has a

Carrier component 55 and a mechatronic installation component 56. The carrier component 55 is designed as a frame on which the mechatronic

Installation component 56 is mounted. This frame has dimensions which make it possible to displace the carrier component 55 vertically within the elevator shaft 51, that is, for example, to move to different vertical positions on different floors within a building. In the example shown, the mechatronic installation component 56 is designed as an industrial robot 57, which is attached to the frame of the carrier component 55 so as to hang downwards. One arm of the industrial robot 57 can be moved relative to the carrier component 55 and, for example, be shifted toward the shaft wall 54 of the elevator shaft 51.

The carrier component 55 is connected via a serving as a support means 58 steel cable with a displacement component 59 in the form of a motor-driven winch, which at the top of the elevator shaft 51 at a stop 60 on the ceiling the elevator shaft 51 is attached. By means of the displacement component 59, the mounting device 53 can be displaced vertically within the elevator shaft 51 over an entire length of the elevator shaft 51.

The mounting device 53 also has a fixing component 61, by means of which the carrier component 55 can be fixed within the elevator shaft 51 in the lateral direction, that is to say in the horizontal direction.

10 shows an enlarged view of a mounting device 53.

The carrier component 55 is designed as a cage-like frame in which a plurality of horizontally and vertically extending spars form a mechanically loadable structure.

At the top of the cage-like support component 55 tethers 62 are attached, which can be connected to the support means 58.

In the illustrated embodiment, the mechatronic installation component 56 is implemented using an industrial robot 57. It should be noted, however, that the mechatronic installation component 56 can also be realized in other ways, for example with differently shaped actuators, manipulators, effectors, etc. In particular, the installation component could be a specially designed for use in an installation process within a hoistway 51 of a

Elevator installation 52 have adapted mechatronics or robotics.

In the illustrated example, the industrial robot 57 with several order

Swivel axes equipped with pivoting robot arms. For example, the industrial robot may have at least six degrees of freedom, that is, an assembly tool 63 guided by the industrial robot 57 may be moved in six degrees of freedom, that is, for example, three rotational degrees of freedom and three translational degrees of freedom. For example, the industrial robot can be designed as a vertical articulated robot, as a horizontal articulated robot or as a SCARA robot or as a Cartesian robot or gantry robot.

The robot can at its cantilever end with various assembly tools 63 are coupled. The assembly tools 63 may be in terms of their

Design and its intended purpose. The mounting tools 63 may be held to the carrier component 55 such that the cantilevered end of the industrial robot 57 can be approached and coupled to one of them. The industrial robot 57 can do this for example via a

Have tool change system, which is designed so that it allows at least the handling of several such assembly tools 63.

One of the assembly tools 63 may be configured as a drilling tool, similar to a drill. By coupling the industrial robot 57 with such

Drilling tool, the installation component 56 may be configured to allow at least partially automated controlled drilling of mounting holes in one of the shaft walls 54 of the elevator shaft 51. The drilling tool can be moved and manipulated by the industrial robot 57 in such a way that the drilling tool drills holes with a drill at a designated position, for example in concrete of the shaft wall 54 of the hoistway 51, in the later example fasteners in the form of screw anchors for fixing elevator part holders can be screwed.

Another assembly tool 63 may be configured as a screwdriver to at least partially screw screw anchor in previously drilled mounting holes in a wall 54 of the elevator shaft 51.

Furthermore, a magazine component 64 may be provided on the carrier component 55. The magazine component 64 may serve to store elevator part holders 10 to be installed and to provide the installation component 56. In the magazine component 64 and screw anchors can be stored and provided using the

Installation component 56 can be screwed into prefabricated mounting holes in the shaft wall 54.

In the example shown, the industrial robot 57 can, for example, automatically grasp a screw anchor from the magazine component 64 and incompletely drilled, for example, with a mounting tool 63 designed as a screwdriver

Screw in fixing holes in the shaft wall 54. Subsequently, a Assembly tool 63 are changed at the industrial robot 57 and, for example, an elevator part holder 10 are gripped from the magazine component 64. The elevator part holder 10 has the recesses 16 described. Of the

Elevator part holder 10 is then fixed as described in connection with FIGS. 3 to 5 on the shaft wall 54, which is in turn reconfigured before the further insertion of the screw anchor on the trained as a screwdriver mounting tool 63.

In the illustrated example, it can be seen that by means of the mounting device 53, an installation process in which elevator part holders 10 are mounted on a shaft wall 54 can be completely or at least partially automated by the installation component 56 first drilling mounting holes in the shaft wall 54 and then lift part holders 10 fastened by means of screw anchors in these mounting holes.

Such an automated installation process can be carried out relatively quickly and can, in particular, help with considerable repetitive installation work to be carried out several times within a hoistway

Installation effort and thus save time and costs. Since the mounting device can perform the installation process largely automated, can

Interactions with human installation personnel are avoided or at least reduced to a low level, so that otherwise typically occurring risks in the context of such installation processes, in particular accident risks, can be significantly reduced for installation personnel.
