Description

The present invention relates to a slide rail assembly for a door operator, with a slide rail and a lockable in the slide rail slider.

The term "door operator" is to be understood as meaning both door closers, servo door locks and door drives. Usually, door operators have an output shaft. By rotation of the output shaft, the door is moved or is moved by moving the door, the output shaft in rotation. The door operator can be mounted either on a wall or a frame and directly on the door leaf. If the door operator is attached to the wall or to the frame, a slide rail lever transmits the force from the output shaft to the sliding rail fastened to the door leaf. If the door operator is attached to the door leaf, the slide rail lever transmits the force from the output shaft to a sliding rail fastened to the wall or frame. The lever is connected slide rail side with a slider. This slider is linearly guided in the slide rail. There are several known ways to set the slider in the slide rail and thus to set the door leaf at a certain opening angle. However, these prior art arrangements are relatively weak or bulky and can hold door wings only a certain weight. In addition, it is often required that the blocking of the door leaf is automatically released, for example in case of fire, so that the door closes.

It is an object of the present invention to provide a slide rail assembly for a door operator, the cost-effective production and Mounting a secure setting and releasing the slider allows. At the same time a comfortable use of the door when opening and closing should be possible.

The object is achieved by the combination of features of claim 1. The dependent claims show preferred developments of the invention.

Thus, the object is achieved by a slide rail arrangement for a door operator, comprising a slide rail and a slider guided linearly in the slide. The slider is adapted to be connected by a lever to the output shaft of a door operator. As a door operator, for example, door closers, Servotürschlie-βer or door drives can be used. To set the slider in the slide and thus to set the door at a certain opening angle a ball lock pin mechanism for setting and releasing the slider is disposed within the slide. The ball lock pin is connected in the preferred variant with the slide rail. The slider is fixed to the balls of the ball locking pin, in particular form-fitting. By pressing the ball locking pin in the ball lock pin mechanism, the balls are released and thus released the slider. Alternatively, the slider may be firmly connected to the ball lock pin. Then the slide would enter into a positive connection with the balls when setting. Advantage of this ball lock pin mechanism within the slide rail assembly is that on the balls a very reliable form fit for holding the slider or for holding the door leaf is formed. At the same time, however, due to the ball lock bolt mechanism, the connection can be released again with relatively small forces. The arrangement according to the invention is therefore particularly suitable for very large doors, in which at the same time a relatively small size of the slide rail is required.

Preferably, the slide rail assembly comprises an electromagnet for actuating the ball lock pin mechanism. In particular, the electromagnet is arranged such that it sets the slider in the state in which the circuit is permanently energized. Thus, in case of power failure or in case of fire by Stromlosschalten the electromagnet, the slider will be released and thus the door will be closed. The electromagnet acts in particular on the ball lock pin of the ball lock pin mechanism, so that with relatively small electromagnet or relatively low voltage, the ball lock pin mechanism can be actuated.

In addition, the slide rail assembly particularly preferably comprises an electrical or electronic switch for detecting an initial movement of the fixed slider. The initial movement of the fixed slider is a slight displacement of the slider in the linear direction of the slide resulting from a user-carried movement on the door. Based on this initial movement, the switch can determine that a user wants to close the door. The electromagnet is adapted to actuate upon detection of this initial movement the ball lock pin mechanism and release the slider. It is particularly preferably provided that the fixed slider is slightly displaceable against a spring force in the slide, so that based on this slight displacement with the switch, the initial movement is detectable. This slight displacement is a displacement of the slider against the spring force by a few millimeters to, in particular, at most 5 cm.

In a particularly preferred embodiment, the ball lock pin mechanism comprises a sleeve for receiving at least one ball, a ball lock pin and a Umgriffselement. In particular, there are a plurality of balls distributed around the circumference of the sleeve in the sleeve. Includes the sleeve per ball a through hole in which the respective ball is arranged freely movable. The ball lock pin protrudes into this sleeve and includes two different diameters. With a first ball bearing diameter on the ball lock pin, the balls are pushed outward and thus are in an extended position. This first ball bearing diameter on the ball lock pin corresponds approximately to the inner diameter of the sleeve. Furthermore, the ball lock pin has a second ball bearing diameter, which is smaller than the first ball bearing diameter, for holding the at least one ball in a retracted position. This second ball bearing diameter is realized in particular by a taper or constriction on the ball lock pin. Thus, by a linear movement of the ball locking pin, the at least one ball can be held in the retracted or in the extended position. The Umgriffselement is located on the component to be fixed, in particular on the slider. This Umgriffselement engages behind the balls in their extended position, so that a positive connection between the balls and the Umgriffselement or the slider is formed. While the slider is fixed to the balls, acting on the ball lock pin no force in the linear direction, so that only a very small holding force must act on the ball lock pin to set an almost arbitrarily heavy door.

In a particularly preferred embodiment, it is provided that the ball lock pin comprises a restoring portion projecting beyond the sleeve. This return portion extends in the direction of the Umgriffselements or in the direction of the slider. In particular, the first ball bearing diameter is formed at this return portion or the first ball bearing diameter is between this return portion and the second ball bearing diameter. The return portion is arranged such that the ball lock pin at a driving of the slider is movable or resettable on the Rückstellanteil. In the non-fixed position of the slider, this slider moves when moving the door leaf linearly in the slide rail. In this case, the ball lock pin is in a position in which the balls are located on the second ball bearing diameter. Now, if the door is opened so far that the slider ascends on the ball lock pin mechanism, the slider or the Umgriffselement touches this reset portion. As a result, is displaced by linear displacement of the slider over the return portion of the ball lock pin. In this position, the Umgriffselement already engages behind the balls in the sleeve, so that the extending when moving the ball locking bolt balls can enter into positive engagement with the Umgriffselement.

Furthermore, it is preferably provided that the ball lock pin is designed as an armature and protrudes through the electromagnet. The anchor can be connected as a separate component with the ball lock pin or the armature or the ball lock pin are integrally formed. In particular, there is a plate or disc on the anchor. This plate or disc corresponds approximately to an end face of the electromagnet and serves to transmit the magnetic force from the electromagnet to the armature. In particular, this disk or plate is at the fixed end slider on the electromagnet on.

Furthermore, a biasing spring is preferably provided, which loads the ball lock pin in the release direction. The "release direction" is the direction in which the slider moves away from the ball lock pin mechanism. The opposite direction is called the reverse direction. As a rule, the release direction corresponds to a closing movement of the door. A "load in the release direction" means that a force acts on the ball lock pin in the release direction by the biasing spring. This biasing spring facilitates release of the locked ball lock pin mechanism. In the locked state, in particular, the plate or disc described above abuts the end face of the electromagnet. When the electromagnet is switched off, this plate would not easily come off the electromagnet. Therefore, this biasing spring is preferably provided which can not move the ball lock pin when energized electromagnet, but can move the ball lock pin linearly when Stromlosschalt the electromagnet, thus releasing the slider. The biasing spring is supported at one end against the ball lock pin or against the armature connected to the ball lock pin. At the other end, the biasing spring is particularly preferably supported against a driver device. This driver device is firmly connected to the sleeve of the ball lock mechanism. Thus, if the slider in the release direction, ie usually in the closing direction of the door, charged at fixed slider, so the wrench pulls on the balls and thus simultaneously on the sleeve. Due to the fixed connection between the sleeve and driver device, the driver device is simultaneously moved in the release direction. This initial movement is detected by the switch described above and the solenoid is de-energized. Then, the biasing spring can relax and the ball lock pin is moved in the release direction. This disengages the ball lock bolt mechanism and releases the slider.

Furthermore, a rod mounted linearly in the slide rail and a further spring loading the rod in the release direction are particularly preferably provided. This further spring causes an initial initial movement or a slight displacement of the fixed slider against the spring force, so that by means of the switch actuation of the fixed door by a user is detectable. The biasing spring is at one end against this rod and the other end against the ball lock pin or connected to the ball lock pin Anchor supported. The end of this rod, which bears against the biasing spring, is part of the driver device described above. In particular, this rod extends through a fixed in the slide block. On one side of the block, the biasing spring is arranged and on the other side of the block is the other spring. This additional spring is placed on the pole and is supported at one end against the block and at the other end against a spring-force adjustment unit.

Particularly preferably, it is further provided that the electromagnet and / or the sleeve during operation of the slide rail assembly, so not only when setting the desired blocking opening angle, are guided linearly movable in the slide rail. In particular, the solenoid and the sleeve are guided linearly so that they join the initial movement or the slight displacement of the fixed slider. The above-described block for guiding the rod is fixed in the slide rail and is linearly displaced only for setting the desired lock opening angle in the slide rail.

The following is based on the Fig. 1 to 6 the structure of the slide rail assembly according to the invention and the movement within the slide rail assembly when opening and closing the door explained. In each of the figures, the left-hand illustration shows a plan view of the slide rail arrangement 1. The right-hand illustration shows a section through the slide rail arrangement 1.

The structure of the slide rail assembly 1 is based on Fig. 1 explained in detail. The individual components are the same in all figures. The Fig. 1 to 6 differ only in the position of the respective components.

The slide rail assembly 1 comprises a slide rail 2 and a slider 3 linearly guided in the slider 3. If the door operator, for example, attached to a wall or a frame, the slide rail 2 is mounted on a door leaf. From the door operator, a slide rail lever extends to the slider 3. For blocking this slider 3 within the slide rail, the slide rail assembly 1 comprises a ball lock pin mechanism 4 between the slider 3 and the slide rail 2.

The ball lock pin mechanism 4 comprises a ball lock pin 5, a sleeve 8, a plurality of balls 9 and a wrapping element 10. The ball lock pin 5 comprises a first ball bearing surface 6 with a first ball bearing diameter and a second ball bearing surface 7 with a second ball bearing diameter. The second ball bearing diameter is made smaller here than the first ball bearing diameter. In particular, the second ball bearing surface 7 is formed as a taper or constriction of the ball locking pin 5. In the sleeve 8 a plurality of through holes are formed distributed on the circumference. In these through-holes sit several balls 9. In the in Fig. 1 shown position, the balls 9 are on the first ball support surface 6 and are thus in an extended position. This wraparound element 10 engages behind the balls 9 and thus leads to a positive connection between the balls 9 and the slider 3. At its right end, the ball lock pin 5 has a reset portion 33, the function in Fig. 5 will be explained in more detail.

The figures show only a section of the slide rail assembly 1. In particular, the slide rail 2 extends to the right. In this direction, the released slider moves when closing the door leaf. This direction is referred to as the release direction 31. The opposite direction is referred to as blocking direction 32.

The locking direction side of the sleeve 8 is an electromagnet 11 in the slide rail 2. The ball lock pin 5 here comprises an armature 12, wherein the armature 12 is coupled as a separate component with the ball lock pin 5. The armature 12 is arranged colinearly with the ball lock pin 5. The armature 12 extends through the electromagnet 11 therethrough. A first end 13 of the armature 12 is connected to the ball lock pin 5. A second end 14 of the armature 12 projects on the other side of the electromagnet 11 out of the electromagnet 11. Between the sleeve 8 and the electromagnet 11 is inserted on the armature 12, a plate 15. This plate 15 corresponds approximately to the frontal surface of the electromagnet 11. In the in Fig. 1 shown fixed position of the slider 3, the plate 12 is the front side of the electromagnet 11 at.

The locking direction side of the electromagnet 11 is a solid block 16 in the slide 3. This fixed block 16 may also be referred to as a guide device. The fixed block 16 is shifted only to set a desired blocking opening angle. Otherwise, this block 16 is stationary in the slide rail 2. In this block 16, a rod 17 is linearly guided. The rod 17 has a first, the electromagnet 11 facing rod end 18 and a second rod end 19. The second rod end 19 is located on the other side of the block 16. At the first rod end 18, a first stop 21 is formed on the rod 17. Against this first stop 21, a biasing spring 20 is supported. The other end of the biasing spring 20 is supported against a second stop 22. This second stop 22 is connected via a coupling 24 to the second end 14 of the armature 12. This coupling 24 is designed in particular as a linear freewheel. This means that the armature 14 rests on this second stop 22, so that the armature 12 and thus the ball lock pin 5 in the release direction 31 can lift off from the second stop 22 and thus from the biasing spring 20. In the blocking direction 23, the armature 12 in turn comes to rest on the second stop 22 or on the pretensioning spring 20.

This spring 25 is supported at one end against the block 16 and the other end against a Federkraftverstelleinheit 26. The Federkraftverstelleinheit 26 is screwed onto the second rod end 19. By Twisting this spring force adjuster 26 on the rod 17, the force of the other spring 25 can be adjusted.

The first stop 21 on the first rod end 18 is engaged behind the locking direction by a driver 27. This driver 27 is firmly connected to the sleeve 8. Thus, upon movement of the sleeve 8 in the release direction 31, the first stop 21 is pulled along. As a result, when the sleeve 8 moves in the release direction 31, the rod 17 and the electromagnet 11 simultaneously move in the release direction 31. The movement of the sleeve 8 in the release direction 31 takes place counter to the spring force of the further spring 25.

In particular, the ball lock pin 5 inserted linearly displaceable on the armature 12. It acts between the ball lock pin 5 and the armature 12, in particular the plate 15, an intermediate spring 23. This intermediate spring 23, the biasing spring 20 and the other spring 25, in particular as helical compression springs educated.

The slide rail assembly 1 further comprises a switch 28 with a probe element 29. This probe element 29 abuts on the driver 27 and thus detects a linear movement of the driver 27. Finally, the switch 28 can detect the linear motion at various positions. Thus, the probe element 29 could also rest on the rod 17 or, for example, on the sleeve 8 or directly on the slider 3.

In addition, the slide rail assembly 1 has a linear guide 30 for linear guidance of the electromagnet 11 and the sleeve 8.

The following is based on the Fig. 1 to 6 the movement within the slide rail assembly 1 when releasing and re-setting the slider 3 described.

Fig. 1 shows the slider 3 in fixed position. The electromagnet 11 is energized and holds on the plate 15, the armature 12 and the ball lock pin 5 in the position shown. The first ball bearing surface 6 with the first ball bearing diameter is located at the height of the balls 9. As a result, the balls 9 are in the extended position. The gripping element 3 engages behind the balls 9 and is thus fixed on the positive connection.

Fig. 2 shows the slide rail assembly 1 at an initial movement of the slider 3. Here, the door is closed by hand. As a result, the slider 3 moves in the release direction 31. About the wraparound element 10, the movement is transmitted to the balls 9 and thus to the sleeve 8. As a result, the rod 17 is displaced in the release direction 31 against the spring force of the other spring 25. Thus, the initial movement of the slider 3 is spring-loaded by the further spring 25. The movement of the driver 27 in the release direction 31 is detected by the probe element 29 and the switch 28. By means of the switch 28, the electromagnet 11 is switched de-energized.

Fig. 3 shows how due to the electroless circuit of the electromagnet 11 and due to the spring force of the biasing spring 20, the plate 12 is released from the electromagnet 11. Simultaneously with the plate 15, the armature 12 and the ball lock pin 5 shifts in the release direction 31. As a result, the balls 9 slide on the second ball bearing surface 7 with the second ball bearing diameter. In this retracted position, the balls 9 no longer protrude beyond the outer circumference of the sleeve 8. As a result the positive connection between the balls 9 and the gripping element 10 is released and the slider 3 is released. For example, in case of fire can be switched off without an initial movement on the slider 3, the electromagnet 11, so that the slider 3 is released.

Fig. 4 shows the released slider, which is freely movable in the entire area to the right of the ball lock pin mechanism 4 within the slide 3.

Fig. 5 shows the slider 3 when driving on the ball lock pin mechanism 4, ie when re-opening the door leaf up to the set blocking opening angle. At a position in which the Umgriffselement 10 already engages behind the through holes in the sleeve 8 and the balls 9, the Umgriffselement 10 and the slider 3 comes simultaneously in contact with the restoring portion 33 on the ball lock pin 5. As a result, by further displacement of the Slider 3 in the reverse direction 32 on the return portion 33 and he ball lock pin 5 in the reverse direction 32 moves. As a result, the balls 9 are again moved to the first ball bearing surface 6 and thus in the extended position. The driver 27 is here already retracted via the rod 17 and the further spring 25 in the locking direction 27, so that the switch 28 is closed and the electromagnet 11 is energized. With the driving of the slider 3 on the return portion 33, both the ball lock pin 5 and the armature 12 moves slightly in the reverse direction 32. This results in the renewed contact of the plate 15 on the front side of the electromagnet 11 and consequently for holding the armature 12 and the Ball lock pin 5 in the in Fig. 6 position shown.

In the in Fig. 6 shown position, the Umgriffselement 10 and thus the slider 3 are moved only a few millimeters in the release direction 31. Then it comes to the positive connection between the Umgriffselement 10 and the balls 9 and the in Fig. 1 illustrated starting position with fixed slider. 3

The present invention presented ball pin locking mechanism 4 in the slide rail assembly 1 allows a setting very heavy doors, at the same time the entire slide rail assembly 1 remains relatively kleinbauend. It is a release of the determination both manually by pulling on the door and in an emergency by Stromlosschalten the electromagnet 11 possible. The wear parts have been largely reduced, so that a low-maintenance operation is possible.
