Description

Alignment device and method for aligning a

Guide rail of an elevator system

The present invention relates to an alignment device for aligning a guide rail of an elevator installation. The invention also relates to a method for aligning a guide rail of an elevator installation and to one with the

Alignment device equipped elevator system.

In elevator systems, elevator cabins are usually vertical within a

Relocated elevator shaft between different levels or floors. The elevator car is usually guided by one or more guide rails during its displacement movement. A guide rail is anchored to a side wall of the guide shaft. The guide rail must be able to absorb the forces exerted on it by the elevator car, mainly in the horizontal direction, and to transfer them to the elevator shaft wall. The same guide rails or additional guide rails can be used to guide one or more counterweights during their displacement movement through the elevator shaft.

In order to be able to guide the elevator car and / or the counterweight precisely, the guide rails must generally be aligned very precisely. As a rule, the guide rails should be exactly vertical, i.e. perpendicular to the

Lift shaft walls are attached. Deviations from a precise one

The positioning or orientation of the guide rails should be as small as possible, for example less than a few millimeters, in order to be able to keep wear-promoting loads on components of the elevator system low when moving the elevator car and / or the counterweight and / or to be caused by the guidance on the guide rails To minimize vibrations on the elevator car while it is traveling and thus improve the comfort of the elevator system.

Conventionally, guide rails are attached to shaft walls with the help of so-called rail bracket parts (English: brackets). Typically a The lower part of the rail bracket is attached directly to one of the shaft walls, for example by screwing it to dowels or counterparts that have been concreted in beforehand. One

Upper rail bracket part is then attached to the lower rail bracket part. The rails should then be able to be attached to the upper part of the rail bracket. Before the upper rail bracket part is firmly fixed to the lower rail bracket part, for example with the aid of screws, the two parts can be displaced relative to one another. By displacing the two rail bracket parts in relation to one another, the rail bracket upper part can be brought into such a position and / or orientation that the guide rail attached or to be attached to it can be arranged with a desired positioning within the elevator shaft.

So far, within the scope of assembling an elevator system, the rail bracket lower parts are usually attached to suitable positions within the elevator shaft, then the rail bracket upper parts are loosely attached to the rail bracket lower parts and the guide rails are fixed to the rail bracket upper parts. The upper rail bracket parts can then be shifted laterally relative to the lower rail bracket parts, for example by a few millimeters or even a few centimeters, for example by shaking the guide rail attached to it or moving the guide rail in the desired direction with hammer blows from the side.

In WO 2018/095739 A1, a method and an alignment device for mounting or aligning a guide rail in an elevator shaft are described. In JP 2829194 (corresponds to JPH06024667) a device and a method for aligning and fixing elevator guide rails are described.

Aligning guide rails in a guide shaft was previously difficult to implement with high precision and / or required an experienced installer.

Among other things, there may be a need for an alignment device and a method for aligning a guide rail of an elevator system, with the aid of which the guide rail can be positioned easily and / or with high precision and / or orientation can be aligned. Furthermore, there may be a need for an elevator installation with such an alignment device.

Such a need can be met by the objects according to one of the independent claims. Advantageous embodiments are defined in the dependent claims and the description below.

According to a first aspect of the invention, an alignment device for

Proposed alignment of a guide rail of an elevator system. The

Alignment device has at least two rail bracket parts in the form of a

Rail bracket lower part and a rail bracket upper part and at least a first and a second displacement element. The lower part of the rail bracket is configured to be fixed to a shaft wall of an elevator shaft. The

The upper part of the rail bracket is configured to hold a guide rail of the elevator system that is fixed to it. The lower rail bracket part and the upper rail bracket part each have a connection area and are above the respective

Connection areas can be fixed to one another. The displacement elements are configured to displace the lower rail bracket part relative to the upper rail bracket part. Each of the displacement elements interacts both with the connection area of the rail bracket lower part and with the connection area of the rail bracket upper part, the displacement element being rotatable about an axis of rotation and interacting with at least one of the rail bracket parts eccentrically with respect to the axis of rotation on mutually opposite contact surfaces in the connection area of this rail bracket part.

According to a second aspect of the invention, an elevator system is proposed with an elevator car guided in its vertical movement by a guide rail and an alignment device according to an embodiment of the first aspect of the invention. The lower rail bracket part is attached to a shaft wall and the guide rail is attached to the upper rail bracket part.

According to a third aspect of the invention, a method for aligning a guide rail of an elevator system is proposed, wherein the guide rail is attached to the upper rail bracket part of an alignment device according to an embodiment of First aspect of the invention is attached. The method here comprises aligning the guide rail by displacing the upper part of the rail bracket relative to the

Lower rail bracket part of the alignment device by rotating at least one of the displacement elements of the alignment device.

Possible features and advantages of embodiments of the invention can be viewed, inter alia and without restricting the invention, as being based on the ideas and findings described below.

As already indicated in the introduction, the alignment of a guide rail of an elevator system is intended to be simplified and / or carried out more precisely, for example in the context of assembly or maintenance.

To summarize briefly, an alignment device is proposed for this purpose, in which two rail bracket parts with the aid of two as eccentrics

trained displacement elements can be displaced relative to each other. The displacement elements interact with the two connecting areas of each of the rail bracket parts and can be rotated about an axis of rotation. At least one eccentrically designed part of a displacement element rests laterally on a contact surface in the connection area of one of the rail bracket parts, so that when the displacement element is rotated about its axis of rotation, the eccentrically designed part of the displacement element laterally moves the contact surface and thus the connection area of the respective rail bracket part. The displacement element can be rotated simply and precisely with the aid of a tool, for example, and the rotational movement can be converted simply and intuitively into a lateral displacement movement of the two rail bracket parts relative to one another.

The two rail bracket parts can be mechanically highly resilient components in order to be able to absorb the forces exerted on the guide rail held on it by the elevator car to be guided or the counterweight to be guided without damage and to be able to divert them to an elevator shaft wall, for example. The rail bracket parts can, for example, be made of metal, in particular steel. Each of the rail bracket parts can be in one piece. For example, a rail bracket part can be formed from a sheet metal, in particular a thick steel sheet. The rail bracket parts can as a rail bracket lower part on the one hand and as

On the other hand, the upper part of the rail bracket may be formed. The two rail bracket parts can have the same, similar or different configuration. The lower part of the rail bracket is designed to be fixed to a shaft wall of an elevator shaft. The lower part of the rail bracket can be attached directly to the shaft wall. Alternatively, the lower part of the rail bracket can also be fastened to the shaft wall by means of additional components such as intermediate pieces, holders or the like. For this purpose, the lower part of the rail bracket can, for example, have recesses through which screws or other fastening elements can extend. In a similar way, the upper part of the rail bracket can be designed in such a way that a guide rail of the elevator system can be fixed and held on it. Here, too, direct or indirect attachment is possible and, for example, recesses can be provided through which screws or similar fastening elements used for fastening can be received. No predetermined arrangement of the two rail bracket parts with respect to one another can be derived from the terms rail bracket lower part and rail bracket upper part. These designations are only used to distinguish the two rail bracket parts.

Each of the two rail bracket parts has a connection area. The two rail bracket parts are to be fixed to one another via their two connecting areas. The connection areas have sufficient mechanical strength to be able to absorb and transmit the forces acting on the rail bracket parts. In particular, the connection areas can be designed in one piece with the rest of the associated rail bracket part. For example, a connection area can be a partial area of a sheet metal from which the rail bracket part is formed. According to one embodiment, the connection area can be plate-like, i.e. extend along a plane. In particular, a rail bracket part can be used as an angle component, i.e. with an L-shaped cross section. In this case, the

Connection area can be formed by a leg of this angle component.

When the two rail bracket parts are fixed to one another, their respective connecting areas can extend parallel to one another. This applies in particular to plate-like connecting areas. Both of them can Adjacent connection areas directly to one another, ie touching one another. Alternatively, an intermediate layer, a supplementary component or the like can be interposed between the two connection areas. The two connection areas should be designed in such a way that the two rail bracket parts can be displaced relative to one another parallel to a surface of their connection areas.

In order to be able to fix the two rail bracket parts to one another, recesses can be provided in each of their connecting areas through which they extend

Fixing elements can extend. With the aid of such fixing elements, the two connection areas can be mechanically pressed against one another or mechanically braced with one another and thus fixed to one another. For example, screws, bolts or the like can be used as fixing elements. The fixing elements can, for example, with a thread or the like directly in one of the

Intervene connection areas or interact with this. Alternatively, the fixing elements can be equipped with suitable counterparts such as nuts, cotter pins, quick-release fasteners or the like in order to be able to mechanically brace connecting areas extending between them against one another. In a possible embodiment, a fixing element can also be formed in one piece with one of the connecting areas or on one of the rail bracket parts. As a further possible embodiment, one of the displacement elements can also be designed in such a way that it can also act as a fixing element in addition.

A main task of the relocation elements is to support the two

To be able to move rail bracket parts relative to one another. This has an effect

Displacement element both with the connection area of the rail bracket lower part and with the connection area of the rail bracket upper part. The displacement element can be rotated hemm about an axis of rotation. In the assembled state, the axis of rotation is preferably orthogonal to one

Extension plane of one of the connecting areas aligned.

Here, the displacement element is designed at least in partial areas in such a way that it interacts eccentrically with at least one of the rail bracket parts. That is to say, when the displacement element is rotated about its axis of rotation relative to the rail bracket part, it rests with the lateral surfaces of the eccentrically formed partial area laterally opposite contact surfaces in the connection area of the rail bracket part. Since the eccentrically formed partial area is displaced laterally due to the rotation of the displacement element, a laterally acting force is exerted on the contact surfaces of the respective element by its lateral surfaces

Rail bracket part exercised. Due to this laterally acting force, the two rail bracket parts are displaced relative to one another.

Ultimately, a linear displacement of the two rail bracket parts relative to one another can be brought about by a simple and precise rotary movement of the displacement element.

According to one specific embodiment, a round hole can be formed in the connection area of a first of the rail bracket parts and in the

Connection area of a second of the rail bracket parts can be formed as an elongated hole. The displacement element can have a cylindrical first engagement region centered around the axis of rotation and a cylindrical second engagement region which is arranged eccentrically around the axis of rotation. The displacement element can then with the first engagement area through the round hole of the first

Running rail bracket part and be arranged to run with the second engagement area through the elongated hole of the second rail bracket part.

In other words, a round hole, i. E. a substantially cylindrical through-opening, and at a position corresponding thereto, an elongated hole, i.e. an elongated hole, can be formed in the other rail bracket part. a through opening with an elongated cross section can be formed. Both an inner circumference of the round hole and at least parts of an inner circumference of the elongated hole form contact surfaces via which forces acting in the lateral direction can be exerted on the rail bracket parts or their connection areas.

One of the displacement elements can then have a first and a second

Have engagement area. Both engagement areas can be essentially cylindrical. The engagement areas can possibly have structures close to the surface, such as threads, for example, the dimensions of which are, however, negligible compared to the overall dimensions of the engagement areas, and only represent insignificant deviations from the cylindrical shape of these engagement areas.

The first engagement area extends centered around the axis of rotation of the

Displacement element. A cross section of the first engagement area can essentially be a cross section of the round hole in the connecting area of the

Correspond to the upper part of the rail bracket. The first engagement area can thus be received within the round hole and rotate about the axis of rotation in it.

The second engagement area is arranged eccentrically with respect to the axis of rotation.

A diameter of the second engagement area can essentially correspond to a distance between the opposing contact surfaces, as they are formed by the inner sides of the elongated hole in the connection area of the associated rail bracket part. The second engagement area can thus be received within the elongated hole.

While oppositely directed areas of a surface on the outer circumference of the second engagement area rest against the opposing contact surfaces of the elongated hole in the connection area and can exert forces on them in order to displace the associated rail bracket laterally in a direction transverse to the longitudinal direction of the elongated hole, the second engagement area can move along the longitudinal direction of the elongated hole can be moved within the elongated hole without significant forces being exerted on the associated rail bending part.

According to a specific embodiment, for each of the

Displacement elements can be formed in the connecting area of the first of the rail bracket parts several round holes. The round holes can preferably be arranged along a straight line.

For example, corresponding to each of the displacement elements, two, three, four, five or more round holes in the connecting area of the first of the

Rail bending parts can be provided. The associated displacement element can accordingly run through one of these round holes. Thus, the relative positioning between the first and the second connection area and so that between the two rail bracket parts can be varied as required. The round holes can be arranged adjacent to one another. The round holes can be arranged next to one another along a line, in particular along a straight line. Distances can be provided between the round holes. The distances can be larger, equal to or smaller than a diameter of the round holes. Alternatively, the round holes can overlap along the straight line, so that a kind of elongated hole with locally varying widths results.

According to one embodiment, the first displacement element can interact with at least one of the rail bracket parts eccentrically with respect to the axis of rotation and abut against mutually parallel first contact surfaces, and the second

Displacement element with at least one of the rail bracket parts resting eccentrically with respect to the axis of rotation on mutually parallel second contact surfaces

Working together. The first contact surfaces can extend in a first direction and the second contact surfaces can extend in a second direction. The first and second directions can be non-parallel to each other, i.e. run at a non-zero angle to each other. In particular, the first and second directions can be orthogonal to one another, i.e. run at right angles to each other.

In other words, the at least two displacement elements can

Alignment device be designed eccentrically that each of the

Displacement elements interacts, for example, with its eccentrically arranged second engagement area with contact surfaces on the connecting area of the associated displacement element. In this case, however, the contact surfaces with which the first displacement element interacts and the contact surfaces with which the second displacement element interacts are not arranged parallel, but at an angle to one another.

Correspondingly, forces can be exerted in different lateral directions on the associated contact surfaces and thus on the associated rail bracket part from the displacement elements via their respective eccentric engagement areas by rotating the respective displacement element. Preferably they are first contact surfaces and the second contact surfaces are arranged orthogonally to one another.

Due to the alignment of the first and second contact surfaces running at an angle to one another, forces can be exerted on the first contact surfaces by rotating one displacement element in a first direction and forces can be exerted on the second contact surfaces by turning the other displacement element in a second direction, which is transverse, in particular orthogonal to the first direction. The rail bracket parts can thus be displaced relative to one another in a plane parallel to the surfaces of their connection areas in two spatial directions running perpendicular to one another.

According to one embodiment, the alignment device can also have a third one

Have displacement element.

The third displacement element can be designed the same or similar to the other two displacement elements and interact in the same or a similar way with the connecting areas of the rail bracket parts. In particular, like the other two displacement elements, the third displacement element can have first and second engagement areas and extend through additional round and elongated holes provided for this purpose in the connecting areas of the rail bracket parts.

With the aid of the third displacement element, further forces can be exerted on the rail bracket parts in order to displace them relative to one another. These further forces can in particular be directed and used to thus the

Not only to be able to displace rail bracket parts linearly relative to one another, but also to be able to reorient them relative to one another with a rotary movement.

In this case, according to one embodiment, the third displacement element can interact with at least one of the rail bracket parts eccentrically with respect to the axis of rotation, resting against third contact surfaces that are parallel to one another. The first and third contact surfaces can extend in mutually parallel directions. In other words, two elongated holes can be formed in one of the connecting areas of the two rail bracket parts, the inner surfaces of which form the first and third contact surfaces. These two elongated holes can extend with their respective longitudinal direction in the same direction or in mutually parallel directions. Thus, by rotating the first and the third

Displacement element are exerted on the respective eccentrically arranged engagement areas forces in mutually parallel directions transversely to each of the first and the third contact surface on the corresponding connection area.

Since the two elongated holes are preferably arranged at mutually offset positions with respect to their longitudinal direction, such forces can be used to produce a torque on the corresponding connection area. As a result of such a generated torque, the two rail bracket parts can be reoriented relative to one another by appropriately rotating the first and the third displacement element.

In principle, this can also be achieved if the first and third

Contact surfaces are not arranged in mutually parallel directions. In the event that the first and third contact surfaces are arranged in mutually parallel directions, a rotation of the rail bracket parts relative to one another can, however, be effected in a manner that is particularly intuitive for a technician by the laterally spaced apart first and third

Displacement elements are suitably rotated around their respective axes of rotation.

According to one embodiment, each of the displacement elements has a screw head with which a tool can interact in order to rotate the displacement element about its axis of rotation.

In other words, a structure can be provided at one end of one of the displacement elements with which a tool can engage in order to be able to exert a torque on the displacement element about the axis of rotation of the displacement element. For example, the screw head can be designed as a polygon, for example a hexagon, with which a correspondingly angular tool wrench can interact. With the help of the tool, a technician can easily, precisely and if necessary exert a torque on the respective displacement element with high forces.

According to one embodiment, the displacement element is centered around the

The axis of rotation has a thread.

In other words, a thread can be provided at one end of the displacement element, for example. The thread can extend spirally around the axis of rotation of the displacement element. A nut, for example, can be screwed onto the thread, with the aid of which the displacement element can be held on one of the connecting areas of the rail bracket parts or can be supported on this. Alternatively, the displacement element with this thread can be screwed into a thread that is provided on one of the connecting areas of the rail bracket parts.

According to one embodiment, the alignment device also has an actuator system which is configured to rotate the displacement elements independently of one another about their respective axis of rotation.

In other words, the alignment device can have an actuator system with one or more actuators. An actuator can interact with one of the displacement elements. Alternatively, an actuator can selectively interact with various of the displacement elements via a transmission. The actuator or the actuators can each interact with one of the displacement elements in order to rotate it about its axis of rotation in order to effect a displacement of the two rail bracket parts relative to one another in this way.

Since the actuator system is configured to be able to rotate the displacement elements independently of one another, and since the displacement elements preferably interact with the connecting areas of the rail bracket parts in such a way that rotating each displacement element causes a relative displacement of the two connecting areas in a different direction than that caused by other displacement elements is, by targeted actuation of the actuators and thus targeted rotation of the various displacement elements, a desired displacement of the two Rail bracket parts are effected relative to each other.

According to one specific embodiment, the actuator system has one or more electric motors to rotate the displacement elements independently of one another about their respective axis of rotation. Each electric motor can act as an actuator in order to rotate one or more of the displacement elements. Preferably, a number of electric motors can be equal to a number of the displacement elements and each

Shift element be assigned to an electric motor.

According to a further specific embodiment, the actuator system has a control to control a rotation of the displacement elements in such a way that the

Upper rail bracket part relative to the lower rail bracket part to a

Reference position is moved.

In other words, a controller can be provided for the actuator system, with the aid of which an operation of the actuator or actuators can be controlled. The controller can know the reference position at which, for example, the guide rail held on the upper part of the rail bracket should be arranged. Based on the information about the reference position, the control can then determine the displacement elements of the

Rotate the alignment device by suitably controlling the actuators in such a way that the upper part of the rail bracket, possibly together with the guide rail attached to it, is moved towards the reference position. The reference position can be determined, for example, by measuring a lateral distance to a previously clamped perpendicular.

Embodiments of the alignment device described herein can be used for an elevator installation according to an embodiment of the second aspect of the invention. The elevator system has an elevator car which, when it moves vertically through an elevator shaft, is guided laterally by at least one guide rail. In this case, the lower rail bracket part of the alignment device is used to attach it to a shaft wall, whereas the

Guide rail is attached to the rail bracket upper part.

Accordingly, using embodiments of the also herein

described method according to the third aspect of the invention a position and / or orientation of the guide rail by suitable alignment of the

Rail bracket upper part can be adjusted by turning one or more of the displacement elements of the alignment device.

In particular, it is possible for more than one alignment device with actuators to be arranged on push bar parts at the same time. In particular, at least three alignment devices with actuators on the push bar parts are one

Guide rail arranged. It is particularly advantageous if an alignment device with actuators is arranged on each pair of rail bracket parts of a guide rail.

The arrangement of several alignment devices with actuators on a guide rail enables a particularly precise automated alignment of the guide rail, since an alignment on one rail bracket part can influence a previous alignment of the guide rail on another rail bracket part. The arrangement of several alignment devices with actuators on different rail bracket parts of a guide rail enables either simultaneous alignment on different guide rail parts or a quick check of the

Effects of an alignment on one rail bracket part on the previous alignment on another rail bracket part. The alignment of the guide rail can, for example, take place automatically in an iterative process in which a repeated alignment on different rail bracket parts takes place one after the other.

It is pointed out that some of the possible features and advantages of the invention herein with reference to different embodiments of the

Alignment device, the elevator system equipped with it or the with it

alignment process to be carried out are described. A person skilled in the art will recognize that the features can be combined, adapted, transferred or exchanged in a suitable manner in order to arrive at further embodiments of the invention. Embodiments of the invention are described below with reference to the accompanying drawings, neither the drawings nor the description being to be interpreted as restricting the invention.

Embodiment of the present invention. In the elevator installation 1, an elevator cage 5 can move vertically within an elevator shaft 7. In doing so, it is displaced by means of a rope-like suspension element 9 which is driven by a drive machine 11.

In particular, in order to prevent the elevator car 5 from lateral movements such as, for example, swinging within the elevator shaft 7, it is guided by guide rails 13 during its vertical displacement. The elevator car 5 is supported on the guide rails 13 via guide shoes 14 or the like. The guide rails 13 are each anchored on a shaft wall 15. In order to simplify correct positioning of the guide rails 13 or to be able to change them later, the guide rails 13 are not attached directly to the shaft wall 15, but rather are connected to it via one of the alignment devices 3.

In Figures 2 to 5, an embodiment of an alignment device 3 is shown in different views. The alignment device 3 has two rail bracket parts 17.

One of the rail bracket parts 17 serves as the rail bracket lower part 19 to be fixed to the shaft wall 15. For this purpose, the rail bracket lower part 19 has suitable recesses 21 in the form of elongated holes 23 and / or round holes 25. Fastening elements, such as screws, for example, with which the lower rail bracket part 19 can be anchored to the shaft wall 15, can run through these recesses 21.

The other rail bracket part 17 serves as the rail bracket upper part 27 to hold the guide rail 13 to be fixed thereon. For this purpose, the upper bracket part 27 can, for example, also have suitable recesses 29 in the form of

Long holes 31 and / or round holes (not shown) may be provided.

Each of the rail bracket parts 17 can be designed as a component with an L-shaped cross section. For example, the rail bracket parts 17 can be designed as curved and thick steel sheets provided with the recesses 21, 29. The recesses 21, 29 each extend through one of the legs of such an L-shaped component. The other leg of the component forms a connecting area 33, 35. The lower rail bracket part 19 can be connected with its connecting area 33 to the connecting area 35 of the upper rail bracket part 27, so that both rail bracket parts 17 are fixed to one another.

A plurality of displacement elements 37 ', 37 ", 37"' extend between the rail bracket lower part 19 and the rail bracket upper part 27. The displacement elements 37 ', 37 ",

37 '"are configured to the rail bracket lower part 19 relative to the

Upper rail bracket part 27 to be displaced laterally, that is to say parallel to the planes of extension of their connecting areas 33, 35. Each of the displacement elements 37 ′, 37 ″, 37 ′ ″ interacts both with the connection area 33 of the rail bracket lower part 19 and with the connection area 35 of the rail bracket upper part 27. As described in more detail below with reference to FIG. 6, the displacement elements 37 ', 37 ", 37'" are designed as components which are eccentrically designed at least in partial areas. A displacement element 37 ', 37 ", 37'" is rotatable about an axis of rotation 39 and acts with at least one of the rail bracket parts 17 eccentrically with respect to the axis of rotation 39 against laterally opposite contact surfaces 4G, 41 ", 4G" in the connection area 35 of this rail bracket part 17 together.

In the example shown, a round hole 43 des, 43 is in the connection area 33 of the rail bracket lower part 19 for each of three displacement elements 37, 37 ″, 37 ‘″. 43 provided. Corresponding positions are in the

Connection area 35 of the rail bracket upper part 27 elongated holes 45 ‘, 45“, 45 are provided. The round holes 43, 43 ", 43" ‘and elongated holes 45‘, 45 ", 45" ‘are arranged next to one another and laterally spaced from one another.

As illustrated in FIGS. 6 (a) - (c), each of the displacement elements 37 has a cylindrical first engagement region 47 and a preferably likewise cylindrical second engagement region 49. The first engagement region 47 extends centered around the axis of rotation 39, whereas the second engagement region 49 is formed eccentrically with respect to the axis of rotation 39. A diameter of the second engagement region 49 is considerably larger than a diameter of the first engagement region 47. The first engagement region 47 is provided with a thread 51. One of the first

On the opposite side of the engagement region 47, a stop region 55 is located adjacent to the second engagement region 49. This stop region 55 can likewise be cylindrical. The stop area 55 can have a significantly larger diameter than the second engagement area 49

Displacement element 47 via a screw head 53 with which a tool

Can cooperate in order to be able to rotate the displacement element 37 about its axis of rotation 39.

In the assembled state (as shown in FIGS. 2-4), each of the

Displacement elements 37 ', 37 ", 37"' arranged such that it is with its first

Engaging area 47 through an associated round hole 43 ', 43 ", 43'" in the

Connecting area 33 of the rail bracket lower part 19 runs and with its second engagement area 49 through an associated elongated hole 45 ', 45 ", 45'" in the

Upper rail bracket part 27 runs. A diameter of the round hole 43 ', 43 ", 43'" corresponds essentially to a diameter of the first engagement area 47, so that the displacement element 37 with its first engagement area 47 in relation to the extension plane of the connection area 33 positively into the round hole 4G, 41 ", 4G "intervenes. A width of the elongated hole 45 ', 45 ", 45'" corresponds essentially to a diameter of the second engagement area 49. Inner longitudinal sides of the elongated hole 45 ', 45 ", 45'" form the contact surfaces 4G, 41 ", 4G" on which the displacement element 37 rests laterally with its second engagement area 49. A length of the elongated hole 45 ', 45 ", 45'" is significantly greater than its width, so that the second engagement area 49 together with the entire displacement element 37 ', 37 ", 37'" within the elongated hole 45 ', 45 ", 45'" along its respective

The direction of longitudinal extent and thus can be shifted parallel to the respective contact surfaces 4G, 41 ", 4G".

By rotating one of the displacement elements 37 ', 37 ", 37'" about its axis of rotation 39, a force can be exerted on the contact surface 4G, 41 ", 4G" of the associated elongated hole 45, which interacts with this second engagement region 49, due to the laterally displaced second engagement region 49 ', 45 ", 45'" can be effected. In other words, by rotating the displacement element 37, a laterally acting force between the two connecting regions 33, 35 of the

Rail bracket parts 17 are generated. With the help of this power, the

Rail bending parts 17 are displaced relative to one another. A direction and a measure of such a relative displacement can be influenced, depending on which of the three displacement elements 37 ', 37 ", 37"' how much is twisted. The rail bracket parts 27 can be displaced linearly in different spatial directions parallel to an interface between their connecting areas 33, 35. In addition, the rail bracket parts 27 can be rotated relative to one another with suitable actuation of displacement elements 37 ', 37 ", 37'".

After the rail bracket parts 17 have been brought into a desired position by suitable rotation of the displacement elements 37 ', 37 ", 37'", they can be fixed to one another. For this purpose, for example, a nut 57 on the thread 51 of the

Displacement element 37 ', 37 ", 37'" are screwed and tightened. Alternatively or in addition, in the two connecting areas 33, 35 additional

Recesses can be provided, for example in the form of round holes 59, 61 through which fixing elements such as screws can extend. With the help of the nuts 57 and / or fixing elements, the two connection areas 33, 35 can be mechanically pressed against one another and thus fixed relative to one another.

In the embodiment shown in FIGS. 2-5, the three elongated holes 45 ', 45 ", 45'" are aligned such that the contact surfaces 4G, 41 ", 4G" of adjacent elongated holes 45 ', 45 ", 45'" are in relation to one another non-parallel directions.

For example, the contact surfaces 41 of the first elongated hole 45 ‘run perpendicular to the contact surfaces 41 ″ of the adjacent second elongated hole 45 ″. The contact surfaces 4L, 4L ″ of the two outer and thus not directly adjacent elongated holes 45 ‘, 45 ″ extend in mutually parallel directions.

With such an arrangement of elongated holes 45 ', 45 ", 45'" and displacement elements 37 ', 37 ", 37'" running through them, the upper rail bracket part 27 can be aligned relative to the lower bracket bracket part 19, for example by a technician, in a particularly intuitive manner . For example

To move the upper rail bracket part 27 to the left or right (based on the illustration in FIG. 4), the middle displacement element 37 ″ must be rotated accordingly. If the upper part of the rail bracket 27 is to be moved up or down, both external displacement elements 37 ‘, 37 ″‘ should be rotated in the same way.

If the upper rail bracket part 27 is to be reoriented, ie in its orientation relative are rotated to the rail bracket lower part 19, the two outwardly lying displacement elements 37 ', 37 "' should be rotated in opposite directions.

7 shows a perspective view of connection areas 33, 35 of an alternative embodiment of an alignment device 3. Several pins 63 are coupled to the connection area 33 of the rail bracket lower part 19. At least three of these pins 63 are rotatably held relative to the connection area 33 of the rail bracket lower part 19. These pegs 63 can either interact directly with the connecting area 33 of the rail bracket lower part 19 by, for example, engaging in round holes provided there (not shown in FIG. 7). Alternatively, the pegs 63 cannot themselves engage in the connecting area 33 of the lower part 19 of the rail bracket, but they can do so indirectly

Connection area 33 interaction. For example, these pegs 63 can interact mechanically with others 63 of the pegs 63 which engage in the connection area 33 of the rail bracket lower part 19.

In the example shown in FIG. 7, two elongated holes 45, 45 ″ run in mutually perpendicular directions, whereas a third elongated hole 45 ″ ″ runs obliquely, in particular at a 45 ° angle to the other two elongated holes 45 ‘, 45 ″.

In FIG. 8, an embodiment of an alignment device 3 is shown schematically, which has an actuator 65. The actuator 65 has a

Electric motor 67 which is controlled by a controller 69. The electric motor 67 interacts with a tool 73 via a gear 71. The tool 73 in turn interacts with the screw head 53 of the displacement element 37.

With the aid of the electric motor 67 and controlled by the controller 69, the displacement element 37 can thus be rotated automatically by means of the actuator system 65. A separate electric motor 67 can be provided for each of the displacement elements 37, so that the displacement elements 37 move independently of one another around their respective

Rotation axis can be rotated. Alternatively, a single electric motor 67 can be sufficient to be able to selectively rotate individual ones of the displacement elements 37 with the aid of a gear arrangement likewise to be controlled by the controller 69, for example. If necessary, the controller 69 can have information regarding a reference position to be reached in the course of an alignment process. In this case, the controller can possibly automatically control the rotation of the displacement elements 37 with the aid of the electric motors 67. An alignment process can thus be largely or even completely automated.

It is possible for more than one alignment device with actuators to be arranged on push bracket parts at the same time. In particular, every pair of

Rail bracket parts of a guide rail arranged an alignment device with actuators. This enables either simultaneous alignment

different guide rail parts or a quick check of the

Effects of an alignment on one rail bracket part on the previous alignment on another rail bracket part. The alignment of the guide rail can then take place automatically in an iterative process in which a repeated alignment on different rail bracket parts takes place one after the other.

The round holes 43 provided for a displacement element 37 are arranged adjacent to one another along a straight line. The straight lines relating to round holes 43 for neighboring

Displacement elements 37 run essentially parallel to one another. in the

In the illustrated example, the round holes 43 are laterally spaced from one another. Alternatively, adjacent round holes 43 could partially overlap one another, i. a center-to-center distance between adjacent round holes 43 could be smaller than their diameter. Due to the several round holes 43 available, this can

Upper rail bracket part 27 and the lower bracket bracket part 19 are arranged roughly pre-positioned relative to one another at different positions, depending on which of the round holes 43 the associated displacement element 37 is guided through.

By way of example only, the dimensions of the rail bracket parts 17 can be in a range of a few centimeters or a few decimeters in the lateral direction and a few millimeters in a thickness direction. For example, in the example 9 shows a length of the sheet metal used for the rail bracket lower part 19 being 250 mm ± 30 mm and a width 110 mm ± 20 mm and a thickness of the sheet metal in the range of 5 mm ± 2 mm.
