Description

Guide rails are used in elevator systems to guide elevator cars along an elevator shaft.

In the case of long shaft lengths, guide rails are typically assembled from individual rail elements during assembly.

In elevator systems with linear motors, a large part of the electrics and electronics of an elevator system are accommodated in the space between the elevator rail and the shaft wall.

However, this compact design has the disadvantage that the guide rail has to be removed from the shaft wall for maintenance work, repairs or necessary replacement in the electrical and electronic systems. Due to the modular design of a guide rail composed of individual rail elements, in such a case often only individual rail elements need to be removed and not the entire guide rail. However, the rail elements must be readjusted each time these are removed and reassembled. This involves a considerable amount of work.

It is therefore desirable to be able to carry out maintenance and repair work on the elevator electronics and electronics without the guide rail or individual rail elements of the guide rail having to be completely removed and reassembled on the shaft wall.

The present invention solves this problem by means of a guide rail according to claim 1.

From the JP H06-48672 A Rail elements are known which can be rotated around their mounting, with which they are fastened to a shaft wall, so as to switch between a vertical direction and a horizontal direction in the elevator shaft and thus the direction of travel of a car at the upper and lower ends of the elevator shaft to change the vertical to the horizontal direction or vice versa. US 6 371 249 B1 discloses a guide rail according to the preamble of claim 1.

The present invention makes it possible for inspection purposes to move the entire space between the at least one rail element of the guide rail and the shaft wall, to which the rear side of the at least one rail element faces, by moving the at least one a rail element can be released with respect to the at least one shaft wall without the guide rail or individual rail elements of the guide rail having to be completely removed and reassembled on the shaft wall.

By using suitable fastening means, the at least one rail element can be pivoted, rotated, shifted or moved on at least one fastening means with respect to the at least one shaft wall.

For example, the at least one fastening element of the at least one rail element can have rails and the at least one rail element can be equipped with rollers with which the at least one rail element is mounted so as to be displaceable on the rails of the at least one fastening element with respect to the at least one shaft wall. The at least one rail element can be displaced thereon with respect to the shaft wall to which the rear side of the at least one rail element faces.

A storage of the rail element on rails on which the at least one rail element can be displaced by means of rollers has the advantage that the wear of the at least one fastening means when moving the at least one rail element in order to access the electrical and electronic components located behind it is very low . Instead of rollers, the at least one rail element can also be equipped with ball sockets in which balls are stored. When using rollers, the at least one rail element can be moved in a maximum of two spatial dimensions. The use of balls results in a further degree of freedom, so that the at least one rail element in the elevator shaft can be moved in up to three spatial dimensions. In this way, the at least one rail element can also be moved, for example, on curved or kinking rails with respect to the at least one shaft wall.

A further possibility is an embodiment of the at least one fastening means, which has at least one hinge, around which the at least one rail element is pivotably mounted with respect to the at least one shaft wall. The at least one rail element can be equipped on one or more sides with a large number of hinges.

In addition, the at least one fastening means of the at least one rail element has at least one lock with which the at least one hinge can be connected to the at least one shaft wall and / or the at least one rail element or can be released from the at least one rail element and / or the at least one shaft wall .

In this way, the at least one rail element can have hinges on several sides, so that by inserting or removing the at least one lock, the at least one rail element individually in a desired direction by means of one or more hinges on one of the sides of the at least one rail element with respect to the at least one shaft wall can be pivoted.

The at least one hinge can form a structural unit with the at least one lock.

The at least one lock can be designed, for example, as a pin that connects a hinge element on the rail element side and a hinge element on the shaft wall side. The at least one locking device, designed as a pin, also represents the axis of rotation about which the at least one rail element can be pivoted. By removing or inserting the pin, a hinge can be removed individually put into or out of operation. Thus, all the pins can be removed from the hinges, which are not required for the desired pivoting direction, and only the pins can be inserted which serve as the axis of rotation for the desired pivoting direction.

After maintenance has been completed, the at least one rail element can simply be pivoted back and anchored by reinserting the removed pins in its intended position as part of the guide rail without extensive adjustments, so that the at least one rail element does not inadvertently swerve out of the structure of the guide rail. However, the at least one lock can also be fitted between a hinge element and the at least one rail element or a hinge element and the at least one shaft wall. The at least one lock can also be in the form of screws with which the at least one hinge element is fastened to the at least one shaft wall and / or at least one further rail element. The screws can be removed or inserted as required, whether the at least one rail element should be pivotable with a particular hinge or not.

Another possibility would be to attach the hinges, for example with magnets, to the at least one rail element and / or the at least one shaft wall, so that the hinges that are not required for the desired pivoting direction can be temporarily put out of operation by loosening the magnets.

The assembly of the at least one rail element via at least one, at least one hinge, fastening means, which is fastened to a fixed position on at least one shaft wall, has the advantage that the at least one rail element is simply folded away from the at least one shaft wall for maintenance work and at Completion of the maintenance work can simply be folded back into its intended position without the at least one rail element having to be readjusted with regard to its position in the elevator shaft.

In a further possible embodiment, the at least one rail element can be pivoted with respect to the at least one shaft wall by means of at least one fastening means which has at least one pivotable swivel arm provided with joints. A swivel arm can have any number of hinge-like joints and / or ball joints.

The use of swivel arms as a component of the fastening means has the advantage that the at least one rail element on them, only limited by the length and mobility of the swivel arms, can be moved into any position in the elevator shaft and the at least one rail element can be adjusted into the intended position without laborious adjustment work Position can be pivoted back.

The at least one fastening means on which the at least one rail element is movably mounted can also have at least one telescopic, extendable construction.

By means of such a telescopic construction, the at least one rail element can either be moved orthogonally from the at least one shaft wall, towards which the rear side of the at least one rail element faces, into the elevator shaft or can be displaced parallel to this shaft wall.

With such a construction, the at least one rail element can be shifted steplessly in one plane, so as to free up the space behind it. In the same way it can at least a rail element can be moved back to its intended position in the elevator shaft.

However, the at least one rail element can also be fastened to at least one shaft wall via at least one fastening means such that the at least one rail element can be rotated about at least one axis. A variant represents a single anchor point, arranged on the at least one rail element in a central region, about which the at least one rail element can be rotated. When using a ball and socket joint at the anchor point, the at least one rail element can not only be rotated parallel with respect to the at least one shaft wall to which the rear side of the at least one rail element points, but can also be tilted with respect to the at least one shaft wall.

In order to free up the entire space located behind the at least one rail element, it is advantageous to design the at least one fastening means of the at least one rail element in such a way that the at least one rail element can not only experience a rotating movement by means of the at least one fastening means, but also can be moved, moved or pivoted.

For example, the at least one fastening means of the at least one rail element can have at least one telescopic construction with which the at least one rail element can be displaced, the at least one telescopic construction having an anchor point at its ends facing the at least one rail element, around which the at least one rail element can be rotated.

By combining different fastening means, the at least one rail element can be moved in any spatial direction with respect to the at least one shaft wall. For example, combinations are conceivable that allow the at least one rail element to be displaced parallel to the at least one shaft wall to which the rear side of the at least one rail element faces and can additionally be pivoted or rotated with respect to this by means of hinges.

In order to open up further possibilities for access to the space between the at least one rail element and the at least one shaft wall to which the rear side of the at least one rail element faces, the at least one rail element can be at least simply divided into segments in the vertical direction, wherein at least one segment of the at least one rail element divided in the vertical direction is movably mounted with respect to the at least one shaft wall. This means that each segment of the at least one rail element divided in the vertical direction has at least one fastening means with which the at least one segment is movably mounted with respect to the at least one shaft wall, or that only a subset of the segments of the at least one rail element divided in the vertical direction is movably mounted, while other segments of the same rail element are rigidly connected to the at least one shaft wall.

In order to reset the at least one rail element, which has been moved out of its guide rail position for maintenance or repair purposes, to its intended exact position, the at least one shaft wall, to which the rear side of the at least one rail element can be facing, have at least one anchor point. The at least one movably mounted rail element can be anchored to the at least one anchor point in a fixed position with the aid of at least one lock. The at least one locking device can be, for example, a hook, a screw, a pin or a magnetic holder. By anchoring the at least one movably mounted rail element, it can be prevented that it is inadvertently moved out of its guide rail position. Likewise, the at least one rail element can be anchored in the vertical direction with at least one further rail element. The at least one rail element is connected to the shaft floor and / or the shaft ceiling and / or to at least one other rail element via anchor points.

In addition, the shaft wall, towards which the rear side of the at least one movably mounted rail element faces, can have markings that simplify the exact positioning of the at least one rail element.

This in Figure 1 The exemplary embodiment shown shows a rail element 1, which is fastened movably with fastening means 2, which have hinges 3, on the shaft wall 4, which faces the rear side of the rail element 1. Two fasteners 2 are attached to the right and left of the rail element 1. The number of hinges 3 can be varied as required.

In the example shown, the rail element 1 is divided centrally into two segments 5 in the vertical direction. It follows from this that each of the two segments 5 is fastened on one side to the shaft wall 4 via two fastening means 2 equipped with hinges 3. The segments 5 of the rail element 1 thus form a type of double door and can be pivoted away separately from the shaft wall 4.

Figure 2 shows a plan view of a rail element 1. On its right and left side, the rail element 1 has fastening means 2, which in turn have hinges 3. The rail element 1 is fastened movably via the fastening means 2 to the shaft wall 4, which faces the rear of the rail element. The hinges 3 form a structural unit with locks 6, which in the exemplary embodiment shown are designed as pins. The latches 6 connect a hinge element on the shaft wall side and a hinge element on the rail element side. A hinge 3 can be put out of operation by removing a lock 6. In this way, by removing the latches 6, designed as pins, from the hinges 3 of the right-hand fastening means 2 of the rail element 1, the rail element 1 can be pivoted away from the shaft wall 4 by means of the hinges 3 of the left-hand fastening means 2 of the rail element 1. The locks 6 of the hinges 3 of the left-hand fastening means 2 of the rail element 1, which are designed as pins, form the axis of rotation about which the rail element 1 can be pivoted. Conversely, the locks 6 of the hinges 3 of the left-hand fastening means 2 of the rail element 1, designed as pins, can be removed and the rail element 1 can be pivoted away from the shaft wall 4 by means of the hinges 3 of the right-hand fastening means 2, the locks 6, which are designed as pins Hinges 3 of the right-hand fastening means 2 of the rail element 1 form the axis of rotation about which the rail element 1 can be pivoted. By reinserting the locks 6 into the hinges 3, the rail element can be firmly connected to the shaft wall 4 again in its intended position, so that the rail element 1 is prevented from inadvertently pivoting out.

Figure 3 shows that in Figure 2 shown rail element 1 in a state pivoted away from the shaft wall 4. Here, the locks 6 were removed from the hinges 3 of the right-hand fastening means 2 of the rail element 1 and the rail element 1 was pivoted by means of its fastening elements 2 on the left-hand side, which have hinges 3. The locks 6 of the hinges 3 of the left-hand fastening means 2 of the rail element 1 form the axis of rotation about which the rail element 1 is pivoted.

Figure 4 shows a rail element 1, the fastening means 2, with which the rail element 1 is movably attached to a shaft wall 4, has rollers 7 and rails 8. The rollers 7 are attached by means of locks 6 to the upper and lower ends of the rail element and are guided in the rails 8 which are mounted on the shaft wall 4. The rail element 1 can be moved laterally parallel to the shaft wall 4.

The locks 6, with which the rollers 7 are attached to the rail element 1, can be individually removed or reinserted. By removing the locks 6, which connect the right (left) side rollers 7 to the rail element 1, the rail element 1 can be pivoted when using suitable locks 6, such as pins. The locks 6 of the left (right) side rollers 7 of the rail element 1 form the axis of rotation about which the rail element 1 can be pivoted.

Figure 5 shows a modification of the embodiment of FIG Figure 4 , in which the rail element 1 is divided into segments 5 in the vertical direction. The segments 5 are equipped with rollers 7 and the segments 5 can be moved laterally separately from one another along rails 8 which are mounted on a shaft wall 4. The rollers 7 are attached by means of locks 6 at the upper and lower ends of the rail element. Just like in the embodiment of Figure 4 In this exemplary embodiment, too, the locks 6, with which the rollers 7 are fastened to the segments 5, can be individually removed or reinserted, which makes it possible for the individual segments 5 not only to be displaced along the rails 8, but also by removing them on one side the locks 6 can also be pivoted from a segment 5. By removing the locks 6, which connect the right (left) side rollers 7 of a segment 5 to the segment 5, the locks 6 of the left (right) side rollers 7 of the segment 5 form the axis of rotation about which the segment 5 can be pivoted .

In the Figures 6 and 7 The exemplary embodiments shown are a variation of the exemplary embodiments from the Figures 4 and 5 , wherein the fastening means 2 instead of rollers 7, balls 9, which are enclosed in ball sockets 10. With the help of the balls 9, a rail element 1 ( Fig. 6 ) or a segment 5 of a rail element ( Fig. 7 ) not only, as in the embodiments of the Figures 4 and 5 , are moved laterally over rails, but can also be moved on curved tracks, for example.

Figure 8 shows a possible embodiment (top view and side view) of a rail 8, as used for guiding in the Figures 6 and 7 illustrated embodiments can be used. The rail 8 has joints in which the balls 9 of the fastening means 2 are guided. In the variant shown, the rail 8 has two joints which extend parallel to one another and extend in the longitudinal direction of the rail 8 and which are connected to one another via further joints (connecting joints). To this A rail element 1 or a segment 5 of a rail element 1 can not only be moved sideways along one of the joints in the longitudinal direction of the rail 8, but can also switch back and forth between them by means of the connecting joints. The joints can be both straight, as in Figure 8 shown, or be curved.

Figures 9 and 10 (Top view of the embodiment of Figure 9 ) show a rail element 1, the fastening means 2 of which has a telescopic construction 12. With the fastening means 2, the rail element 1 is movably mounted on the shaft wall 4, to which the rail element 1 faces with its rear side. Thus, the rail element 1 can be moved away from the shaft wall 4 into the shaft interior by extending the telescopic structures 12 in the orthogonal direction.

The telescopic constructions 12 are each fastened to the rail element 1 and to the shaft wall 4 with releasable locks 6. In the Figures 9 and 10 shown embodiment can with the embodiment Figure 2 and 3 be combined. It is possible that the telescopic constructions 12 have hinges 3 at their shaft wall ends and / or at their ends near the rail element. By removing the locks 6 on one of the sides of the rail element 1, the rail element 1 can not only be moved by means of the telescopic structures 12, but can also be pivoted by means of hinges 3.

Accordingly, it would also be conceivable that in the Figures 9 and 10 shown rail element 1 is divided into segments 5 in the vertical direction. In this case, a combination with the exemplary embodiment is analogous Figure 1 possible.

The Figures 11 and 12 (Top view of the embodiment Figure 11 ) show a slight variation of the embodiment from the Figures 9 and 10 . Here too, the fastening means 2 have telescopic constructions 12. In this case, however, the rail element 1 is not fastened to the shaft wall 4 to which the rear of the rail element 1 faces, but to the two shaft walls 4 to which the right or left side wall of the rail element 1 points. The rail element 1 can be displaced in parallel with respect to the shaft wall 4, to which the rear of the rail element 1 points. When sliding the rail element 1, the telescopic structures 12 arranged on the left (right) side of the rail element 1 are extended, while the telescopic structures 12 arranged on the right (left) side of the rail element 1 are pushed together. The in the Figures 11 and 12 The embodiment shown can also be applied to a rail element 1 which is divided into two segments 5 in the vertical direction. The two segments 5 can be pushed out of their guide rail position separately from one another. The segments 5 can be moved by means of the telescopic constructions 12 in the same direction with one another or in the opposite direction away from one another.

The Figures 13 and 14 (Top view of the embodiment from Figure 13 ) show a further embodiment with which a rail element 1 can be movably mounted on a shaft wall 4. Here, the rail element 1 is fastened with fasteners 2, which have swivel arms 13, on the shaft wall 4, which is at the rear of the rail element 1. The joints of the swivel arms 13 can have hinges 3 and / or balls 9 and ball sockets 10. The swivel arms 13 can have any number of joints.

Instead of on the shaft wall 4 at the rear of the rail element, the swivel arms 13 having fastening means 2 can likewise, analogously to the exemplary embodiment from FIGS Figures 11 and 12 , are attached to the two shaft walls 4, to which the right and left side wall of the rail element 1 point.

By using releasable locks 6 on the shaft-like and / or the rail element ends of the fastening means 2, the rail element 1 can be analogous to that in FIGS Figures 2 and 3 illustrated embodiment can be pivoted even further.

If the rail element 1 is divided in the vertical direction, the individual segments 5 of the rail element 1 can be moved separately.

In Figure 15 have the fastening means 2, with which a rail element 1 is movably mounted on the shaft wall 4, to which the rail element 1 faces with its rear side, on telescopic structures 12, on the ends of which the rail element 1 can be rotated. The telescopic structures 12 have connecting elements 14 at their ends facing the rail element, the main direction of extension of the connecting elements 14 being oriented orthogonally to the main direction of extension of the telescopic structures 12. The connecting pieces 14 positioned between the ends of the telescopic constructions 12 and the rail element 1 form the axis of rotation about which the rail element 1 can be rotated.

Accordingly, by extending the telescopic constructions 12, the rail element 1 can first be moved into the interior of the shaft and then rotated about the axis of rotation formed by the connecting elements 14. In this way, better access to the space between the rail element 1 and the shaft wall 4, to which the rear side of the rail element 1 points when the rail element 1 is in its fixed position as part of the guide rail, is made possible.

Figure 16 shows a modification of the in Figure 15 illustrated embodiment, in which the rail element 1 is divided into segments 5 in the vertical direction. Each segment 5 is movably mounted on the shaft wall 4, to which the rear sides of the segments 5 face in their intended position as part of the guide rail, via fastening means 2, which have telescopic structures 12. The individual segments 5 are rotatably mounted on the telescopic structures 12 by means of connecting elements 14. The connecting elements 14 are arranged between the latter and the segments 5 in the orthogonal direction to the extension direction of the telescopic structures 12.

With fastening means 2 designed in this way, each segment 5 of the rail element 1 can be pushed into the interior of the shaft separately with the telescopic structures 12 and then rotated about the axis of rotation formed by the connecting elements 14.

In addition, the fastening means 2 in the exemplary embodiments from the Figures 15 and 16 have hinges 3 at their shaft wall ends, which can be put into operation individually as required by means of releasable locks 6. By removing the latches 6, the rail element 1 or the segments 5 of the rail element 1 can not only be displaced and rotated, but also pivoted by means of the hinges 3.

In the, in the Figures 15 and 16 The exemplary embodiments shown can also have the fastening means 2 with their ends facing the shaft wall on the shaft walls 4 to which the right and left side walls of the rail element 1 face (as in FIGS Figures 11 and 12 shown).
