Description

The present invention relates to a sliding door arrangement comprising a running rail which defines a longitudinal axis and has a side web and an upper web, a door leaf which is displaceable parallel to a plane formed by the longitudinal axis and a vertical axis oriented perpendicular to the longitudinal axis, the door leaf on two is suspended in the running carriage guided carriage, a damper connected to the door leaf, which is arranged between the two carriages and has a driver, and an activator, which has a coupling element cooperating with the driver, which in a disengaged position disengaged from the Driver and is in a coupled position in engagement with the driver, wherein the activator has a holding portion which is received in a guide recess formed on an underside of the upper web, wherein the guide recess on a side facing the carriage by a n inner guide legs and an outer guide leg is limited, a longitudinal slot being formed between the two guide legs.

From the DE 10 2018 202 813 B3 such a sliding door arrangement is known. The known sliding door arrangement has a multi-part activator with a base body and an adjusting body, the adjusting body being adjustably fastened to the base body by means of screws. The main body of the activator is received in a guide recess formed on the underside of an upper web of the running rail and fixed therein by means of the screws. A coupling element is arranged on the adjustment body and interacts laterally with a driver of a damper.

From the DE 20 2010 013 034 U1 a sliding door arrangement is known which has a one-piece activator with a drop-like catch hook. The catch hook is arranged centrally over the path of the carriage and interacts from above with a driver of a damper held on the carriage. The activator is guided displaceably in a guide recess which is formed on the upper web of a running rail and can be fixed therein in a desired position by means of adjusting screws. In order to simplify both the insertion of the activator laterally into the guide recess and the displacement of the activator along the longitudinal axis of the running rail, a plate of the activator received in the guide recess has two beveled corners with transition radii. As a result, the activator should also be able to rotate to a limited extent within the guide recess in order to fix it therein.

A disadvantage of the prior art mentioned is that the known activators can only be inserted laterally into the guide recess on the upper web of the running rail. However, the side ends of the running rail are usually closed by cover caps, so that the cover caps, among other things, have to be removed when the activator is inserted for the first time or when it may be necessary to replace it.

The object of the present invention is therefore to provide a sliding door arrangement of the type mentioned at the beginning which is easier to assemble and more maintenance-friendly.

This object is achieved in a sliding door arrangement of the type mentioned at the outset in that the holding section is in a release position in which a transverse extension of the holding section oriented perpendicular to the longitudinal axis is less than or equal to a width of the longitudinal slot, and in a blocking position in which the perpendicular to the longitudinal axis aligned transverse extension of the holding section is greater than the width of the longitudinal slot and less than or equal to a clear width of the guide recess, is designed to be rotatable about the vertical axis at a limited angle, and that the holding section has projections which are arranged in the guide recess and which in the locking position Reach behind the guide leg.

The advantage is that the activator can be installed from below. Because in the release position, the transverse extension of the holding section, or its clear width, is narrower than or at most the same size as the width of the longitudinal slot, so that the holding section can be inserted into and removed from the guide recess along the vertical axis through the longitudinal slot. In the blocking position, the transverse extension of the holding section is greater than the width of the longitudinal slot, so that the holding section locks itself in the guide recess and accordingly cannot be removed through the longitudinal slot. The holding section can be rotated about the vertical axis by a limited angular range, for example of at least 5 degrees and a maximum of 45 degrees, in order to transfer the holding section from the locking position to the release position, and vice versa. In order to be able to provide a running rail with a particularly compact design, it is possible to rotate the holding section in the guide recess by a limited angular range of a maximum of 30 degrees. The fact that the holding section of the activator is received from below on the upper web, specifically in its guide recess, also provides a particularly stable connection between the activator and the running rail.

The vertical axis of the sliding door arrangement is aligned perpendicular to the longitudinal axis. In the assembled state of the sliding door arrangement, the vertical axis can run parallel to the direction of gravity. A transverse axis of the sliding door arrangement is perpendicular to the vertical axis and to the longitudinal axis. In the assembled state of the sliding door arrangement, the longitudinal axis spans a horizontal plane together with the transverse axis. The door leaf can be displaced parallel to a plane formed by the longitudinal axis and the vertical axis oriented perpendicular to the longitudinal axis.

The guide recess is delimited towards the carriage, i.e. towards the bottom, by the inner guide leg and the outer guide leg. In particular, the activator can have projections which are arranged in the guide recess and which engage behind the two guide legs in the blocking position. As a result, the holding section or the activator is supported downwards and cannot be removed from the guide recess in the blocking position.

The holding section of the activator preferably has two first edges aligned parallel to one another, which can be of the same length or are of the same length and are aligned parallel to one another, a distance between the two first edges corresponding to the transverse extent of the holding section in the release position. In particular, it is provided that the first edges are aligned parallel to the longitudinal axis in the release position and intersect the longitudinal axis in the blocking position to form a blocking angle, the blocking angle being in a range from 5 degrees to 30 degrees. The blocking angle can predetermine the maximum value of the angular range by which the holding section can be rotated in the guide recess between the release position and the blocking position. In order to simplify the rotation of the holding section in the guide recess, the first edges are arranged at least partially axially offset from one another along the longitudinal axis. It is preferably provided that the first edges overlap axially in an overlap area, an extension of the overlap area along the longitudinal axis corresponding to a maximum of 30 percent of an edge length of the respective first edges. In particular, the extent of the overlap area along the longitudinal axis corresponds to at least 10 percent of an edge length of the respective first edges and is preferably between 20 percent and 28 percent of the edge length of the respective first edges.

Furthermore, it can be provided that the holding section has two second edges, which can be of the same length or are of the same length and are aligned parallel to one another, a distance between the two second edges corresponding to the transverse extent of the holding section in the locking position. The second edges can expediently be outer edges of the projections. This results in a particularly compact structure of the holding section. In particular, the second edges can be aligned parallel to the longitudinal axis in the blocking position and intersect the longitudinal axis in the release position to form the blocking angle, the blocking angle being in a range from 5 degrees to 30 degrees. The blocking angle can predetermine the maximum value of the angular range by which the holding section can be rotated in the guide recess between the release position and the blocking position. The second edges can be arranged at least partially axially offset from one another along the longitudinal axis. The second edges are preferably arranged axially offset from one another along the longitudinal axis.

The guide recess can have two inner walls which extend along the longitudinal axis and which delimit the guide recess between them and define the clear width of the guide recess. In the blocking position, the second edges can be supported on the inner walls of the guide recess in the transverse direction. In this way, the holding section can initially be inserted from below through the longitudinal slot into the guide recess and rotated about the vertical axis by turning. The projections overlap with the inner guide web and the outer guide web and the second edges abut the inner walls of the guide recess. The holding section can then no longer be rotated in this direction of rotation. The direction of rotation preferably corresponds to the direction of rotation of a torque that is generated during the braking process of the door leaf in which the coupling element is in engagement with the driver. This results in a particularly stable support of the activator on the longitudinal rail. It can be provided that the holding section of an activator intended for the left end position and the holding section of an activator intended for the right end position can be designed to be mirrored about an axis, in particular the transverse axis, and can accordingly differ from one another. Alternatively, the activator can also be used on both the left and right end positions without any structural changes.

Preferably, the first edges and the second edges lie in a common plane. In each case one of the first edges can intersect exactly one of the second edges. In particular, one of the first edges can intersect one of the second edges at an edge angle of more than 150 degrees and less than 175 degrees, respectively touch. The edge angle is particularly preferably between 160 degrees and 170 degrees. In particular, the edge angle is 165 degrees. In this way, the holding section can be rotated by in particular 15 degrees to the longitudinal axis in order to transfer the holding section from the blocking position to the release position, and vice versa. Correspondingly, the angular range by which the holding section in the guide recess can be rotated about the vertical axis can be from 0 degrees to 15 degrees.

In one aspect, the first edges can be longer than the second edges.

Both the first edges and the second edges can be designed in a straight line. Furthermore, the holding section can have two third edges aligned parallel to one another, the third edges being shorter than the second edges. The third edges can be designed in a straight line. In order to simplify the rotation of the holding section in the guide recess, a distance between the third edges can be greater than the distance between the second edges. In particular, the third edges can be oriented perpendicular to the longitudinal axis in the blocking position and intersect the longitudinal axis in the release position to form the blocking angle, the blocking angle being able to be in a range from 5 degrees to 30 degrees. The blocking angle can predetermine the maximum value of the angular range by which the holding section can be rotated in the guide recess between the release position and the blocking position. The third edges can lie in a common plane together with the first edges and the second edges.

The holding section preferably has an outer surface facing the upper web, wherein the first edges, the second edges and the third edges can be outer edges of the outer surface. The outer surface can have the shape of a hexagon. As a result, a compact holding section can be provided, which in the release position can be easily inserted through the longitudinal slot, i.e. from below into the guide recess and removed from it again, and in the blocking position securely holds or locks the holding section in the guide recess.

According to one embodiment, the guide recess extends along the longitudinal axis of the running rail. The activator can be fixed displaceably in the guide recess, so that the position of the activator can be freely adjusted along the longitudinal axis during assembly of the sliding door arrangement in order to adapt the damper behavior. Furthermore, it can be provided that the holding section has at least one fastening bore penetrated by an adjusting screw, the holding section being fixed in the guide recess in a continuously adjustable manner by means of the at least one adjusting screw. Such a set screw can also be referred to as a grub screw or clamping screw. Preferably two of the fastening bores and correspondingly two of the adjusting screws are provided.

Furthermore, the guide recess can extend over the entire longitudinal extent of the running rail. In particular, the running rail can have a profile that is constant in cross section along the longitudinal extent. The running rail can for example be a drawn extruded profile, in particular made of a metal, for example aluminum. Such a running rail is easy to manufacture. The running rail preferably comprises a base part, which has the side web and the upper web, and a cover web, which can be placed on the base part from the outside for optical and safety reasons when the sliding door arrangement is installed. The running rail is preferably designed in two parts. The running rail can consist of the base part and the cover web. The activator can then be arranged between the cover web and the carriage in the running rail. The activator preferably ends flush with the upper limb in the transverse direction or is set back in relation to this towards the path of the carriages, in order to create space that may be required for the fascia bar.

In a further embodiment, it can be provided that the activator has an intermediate section which connects the holding section to an arm, the coupling element being arranged on the arm. In particular, the intermediate section is arranged outside the guide recess. The intermediate section can be designed to be particularly flat in order to provide a running rail that is particularly compact in height. The intermediate section can be plate-shaped or flat. In order to provide a compact running rail, an underside of the outer guide leg facing the carriage can be set back from an underside of the inner guide leg facing the carriage. An underside of the intermediate section can end flush with the underside of the inner guide leg or be set back with respect to this. This creates a free space below the outer guide leg, which can be used to arrange the intermediate section on the underside of the upper web so as to be as flat as possible, without structurally restricting the travel path of the carriages. In particular, an upper side of the intermediate section rests flat against the lower side of the outer guide leg.

The holding section and the arm preferably protrude from two sides of the intermediate section facing away from one another. In other words, starting from the intermediate section, the holding section can protrude upwards and the arm can protrude downwards. In order to provide a particularly stable activator, it can be formed from one piece. That is, the activator can be in one piece. In other words, the activator then has no individual parts that would have to be connected to one another during assembly or after its manufacture, in particular screwed to one another.

In particular, the arm with the coupling element is arranged on a side of the carriage on a side opposite the side web. In the locked position, the arm can be aligned parallel to the side web. When the coupling element is in engagement with the driver, the pivoting movement of the door leaf is braked. By engaging the coupling element in the driver on the side of the carriage opposite the side web, a torque is generated around the vertical axis of the door leaf, which presses the door leaf towards the side web. A catwalk, on which the carriages can be supported, preferably protrudes from the side web. In particular, the carriages each have at least one roller on a side facing the side web, which roller is supported on the catwalk. This ensures that the carriages cannot slip off the catwalk and are also safely guided on the catwalk during the braking process. The carriages preferably only have the rollers on the side facing the side web.

In order to secure the activator in the blocking position against rotation about the vertical axis, the intermediate section can have at least one securing hole with an internal thread through which an adjusting screw can penetrate. When the activator is in the inserted state, one screw end protrudes from an upper side of the intermediate section and is arranged in the longitudinal slot. To improve the anti-rotation lock, a distance between an outer circumference of the at least one locking hole or the adjusting screw and the outer guide web can be between 0.1 millimeters and 0.5 millimeters. In this way, the screw end of the at least one adjusting screw protruding from the securing hole strikes the external guide web when the activator is rotated about the vertical axis, which can be generated by the torque in the braking process, and prevents the activator from rotating about the vertical axis. The distance between the adjusting screw and the outer guide web is preferably 0.2 millimeters. Furthermore, the activator can have two of the securing bores with an internal thread, wherein the two securing bores can be arranged on a common straight line which, in the blocking position, runs parallel to the longitudinal axis. This means that the centers of the securing bores can be arranged on a common straight line. This additionally increases the security of the activator against twisting. In the non-rotatable position, the holding section cannot be transferred from the blocking position into the release position. For this purpose, the at least one set screw must first be loosened in the at least one securing hole.

In a preferred manner, the coupling element extends over at least 70 percent of the height of a path in which the carriages are displaceably guided along the longitudinal axis. The path is limited at the top by the upper walkway and at the bottom by the walkway. As a result, the coupling element preferably covers the entire height range in which the driver can move along the side of the arm, so that the coupling element can always safely come into engagement with the driver. In particular, the coupling element extends over at least 85 percent of the height of the path and can extend a maximum of 95 percent of the height of the path. The coupling element can extend over the entire height of the arm in order to provide a particularly stable coupling element. Likewise, the coupling element can also be longer than the height of the arm, so that the coupling element projects downward beyond a free end of the arm.

According to one aspect, the coupling element can be a nose protruding from the arm towards the side web. Furthermore, a recess can be formed in the driver, the nose being out of engagement with the recess in the disengaged position and in engagement with the recess in the coupled position. In this way, a stable and maintenance-friendly coupling connection between the activator and the driver is provided. Furthermore, it can be provided that the driver is guided in a guide track extending along the longitudinal axis. The guide track can have two elongated holes, which can in particular be L-shaped. The elongated holes can be arranged one above the other in relation to a vertical axis oriented perpendicular to the upper web. The driver can have bolts that can be guided in the elongated holes. As a result, the driver is guided displaceably along the longitudinal axis. When the driver engages with two of its bolts in the short hole sections of the two L-shaped elongated holes, the driver is in a parking position in which the driver is tilted about the vertical axis. In this way, the coupling element held to the side of the path can easily come into engagement with the recess of the driver moving along the arm.

Furthermore, the damper can optionally be attached to one of the two carriages. A direct attachment of the damper to the door leaf is not necessary. In particular, the damper can be attached to one of the two carriages in a height-adjustable manner. As a result, the height of the driver, in particular the recess, can be aligned on the coupling part of the activator. The damper can comprise an energy store which is coupled to the driver. In this way, the movement of the door leaf can be at least partially braked for reasons of safety and comfort during the closing process and / or the opening process. The damper brakes the door leaf before it reaches an end stop in order to prevent the door leaf from hitting the end stop hard. The damper absorbs the kinetic energy of the door leaf during the closing and / or opening movement at least partially. The sliding door arrangement preferably has two of the dampers, it being possible for one of the dampers to be attached to each of the two carriages. In this way, the sliding movement of the door leaf can be braked in both sliding directions in order to brake the door leaf before reaching an end stop.

The door leaf can, for example, have a laminated glass pane and can in particular be fully glazed. The door leaf can also comprise, for example, wood material or metallic material.

The sliding door arrangement can have fastening means in order to fasten the running rail to a stationary component, for example a building wall above a wall opening. The fastening means can comprise holes formed in the side web in order to be able to screw the running rail to the stationary component by means of screws. Due to the fact that in the embodiment in which the coupling element interacts laterally with the driver, when the door leaf is braked, the latter is pressed towards the side web, the forces act essentially perpendicularly on the side web during the braking process, whereby the service life of the screw connections can be increased. In principle, however, it is also possible for the running rail to have openings in the upper web in order to be able to screw the running rail to a ceiling. It is also possible for the running rail to be attached to stationary components at both of its longitudinal ends. For example, a running rail held in this way can be provided in a shower arrangement, wherein the two longitudinal ends can be fastened to a support structure for shower glazing or at least one of the two longitudinal ends can be fastened directly to a building wall.

In 1 to 11 there is shown a sliding door assembly in accordance with an embodiment of the present invention. The 1 to 11 are described collectively below. The sliding door assembly has a running rail 1 and a door leaf 2 on that along a through the running rail 1 defined longitudinal axis X is slidably guided. The door leaf 2 can be parallel to a plane E. passing through the longitudinal axis X and one perpendicular to the longitudinal axis X aligned vertical axis Z is formed in the running rail 1 , with view on 1 can be moved both to the left and to the right.

In the 1 to 6th as well as 10 and 11 is a Cartesian coordinate system with the longitudinal axis to illustrate the alignment of the sliding door arrangement in space X , the transverse axis Y and a vertical axis Z drawn. The vertical axis Z runs in the assembled state, in which the sliding door arrangement over the running rail 1 is attached to a stationary component, in particular the building wall, parallel to the direction of gravity. Terms such as "below" or "above" represent spatial information in relation to the sliding door arrangement in the assembled state.

The running rail 1 has a side bar 3 and an upper bridge 4th on. The upper bridge 4th is perpendicular to the side bar 3 arranged and extending along a transverse axis Y . In the side bridge 3 Holes (not shown) may be formed around the running track 1 to be screwed to a building wall (not shown) above a wall opening. Furthermore, the running rail 1 have a cover web (not shown) which, for optical and safety reasons, onto the upper web from the outside 4th can be attached and attached to this. This can be done on the upper web 4th a longitudinal groove 5 be formed, in which, for example, a spring formed on the cover web can be inserted, other types of connection are also conceivable and possible. On both longitudinal ends of the longitudinal rail 1 caps (not shown) can be fitted.

To the door leaf 2 in the track 1 To guide displaceably, the sliding door arrangement comprises two carriages spaced apart from one another 6th , on which the door leaf 2 is fixed hanging. The trolleys 6th are each supported by a roller 7th on one of the side walkways 3 protruding catwalk 8th from. The runway 8th points, here, one along the longitudinal axis X extending channel-like depression 9 on where the casters 7th of the two carriages 6th are movably guided. The two carriages 6th can each have two side parts 10 ', 10 ", which by means of screws 11 are screwed together. Below the screws 11 assign the carriages 6th each have a clamping section 12th on where the door leaf 2 is fixed hanging. Specifically, the two side parts 10 ', 10 "of the respective carriage 6th in the clamping section 12th in the transverse direction Y spaced from each other and hold an upper edge region of the door leaf 2 stuck between them.

There are also two dampers 13th provided to the door leaf 2 , with view on 1 both when moving the door leaf sideways 2 to the left and to the right shortly before reaching the respective end position to be braked in a controlled manner. The two dampers 13th are, here, constructed identically. The two dampers 13th are between the two carriages 6th arranged on each of the carriages 6th one of the two dampers 13th is attached. The respective damper is specific 13th end by means of a holder 14th on the assigned carriage 6th attached. Furthermore, the respective damper is 13th at its free end via a spacer 15th on the door leaf 2 supported. In relation to the longitudinal axis X between the spacer 15th and the bracket 14th of the respective damper 13th this has a driver 16 on, the one with one of two on the running rail 1 fixed activators 17th can come into engagement. A first of the two activators is used for controlled braking 17th just before the left end of the running rail 1 and a second of the two activators 17th just before the right end of the running rail 1 fixed. In the 1 to 3 are exemplary partial sections of the sliding door arrangement around the left end of the running rail 1 shown around. For the right end position (not shown), however, the comments on the left end position apply in an analogous manner.

In 6th is the damper 13th shown as a single component to illustrate its structure. The driver 16 of the respective damper 13th is in a guideway 18th along the longitudinal axis X guided. The respective guideway 18th is on one of the side walkways 3 remote side of the damper 13th arranged and has two along the vertical axis Z L-shaped elongated holes arranged one above the other 19th on. At the respective driver 16 are on two sides facing away from each other two of a total of four bolts 20th arranged to guide the respective driver 16 into the two elongated holes arranged one above the other 19th intervention. Furthermore, the respective damper 13th an energy store 21 on the assigned driver 16 force is applied to the movement of the driver 16 controlled braking when the door leaf 2 moves to the associated end position.

For interaction with the assigned activator 17th instructs the respective driver 16 a recess designed as a groove 22nd on. The recess 22nd extends along the vertical axis Z completely over the driver 16 . Thus is the recess 22nd both up and down as well as to one from the side bridge 3 facing away from the open side.

The two activators 17th are along the longitudinal axis X arranged at a distance from one another and on an underside 23 of the upper bridge 4th fixed. The activators 17th are, here, constructed identically. The following is the structure of the two activators 17th described in detail.

The activator 17th has one from the bottom 23 of the upper bridge 4th protruding arm 24 on, the one on one of the side walkways 3 opposite side of the carriage 6th , or between the fascia bar and the carriage 6th is arranged. The poor 24 is parallel to the side bridge 3 aligned. Looking across Y on the activator 17th can be seen that the arm 24 has the shape of a triangle with the tip of the triangle pointing downwards. On the arm 24 is a coupling element 25th trained that with the driver 16 cooperates. In the 4th FIG. 13 is a sectional view taken along that of FIG 1 shown line IV-IV. It can be seen that the coupling element 25th in engagement with the recess 22nd of the driver 16 is. The coupling element 25th is designed as a nose that is supported by one of the trolleys 6th facing inside of the arm 24 towards the side bridge 3 protrudes. The coupling element 25th extends over about 90 percent of a height H of a walking path 26th that is in height between the catwalk 8th and the upper bridge 4th is limited. To clarify the structure, the 5 Another cross-sectional view of the sliding door assembly is shown with the carriage 6th and the door leaf attached to it 2 are not shown for the sake of clarity.

The coupling element 25th is disengaged from the driver in a disengaged position 16 and in an engaged position in engagement with the driver 16 . In the 2 the disengaged position is shown. The driver 16 is in its parking position, in which two of the bolts 20th of the driver 16 in the short L-bar of the L-shaped elongated hole 19th intervene, causing the driver 16 around the vertical axis Z towards the assigned coupling element 25th tipped. The driver 16 is through the associated energy store 21 biased into the park position. In the 3 and 4th the engaged position is shown. It can be seen that the coupling element 25th into the recess 22nd of the driver 16 intervenes. By sliding the door leaf 2 , with view on 3 , to the left is the driver 16 against the direction of force of the energy store 21 moved, with the door leaf 2 is braked in a controlled manner.

Furthermore, the activator 17th a holding portion 27 on that in one at the bottom 23 of the upper bridge 4th trained guide recess 28 is used. The guide recess 28 runs along the longitudinal axis X and extends over the entire length of the running rail 1 . The guide recess is at the bottom 28 through one of the side walkways 3 nearest internal guide leg 29 and an outer guide leg 30th limited. Between the two guide legs 29 , 30th is a longitudinal slot 31 formed along the longitudinal axis X extends.

The holding section 27 can be inserted into the guide recess from below 28 can be used. For this purpose are in the holding section 27 of the activator 17th two protrusions 32 , 33 formed, the guide legs in a locking position 29 , 30th reach behind. In the 1 to 5 and 11 is the activator 17th shown in the locked position. In the 10 are the protrusions 32 , 33 aligned in such a way that this aligns with the longitudinal slot 31 cover. The activator 17th is then opposite the guide recess 28 released and can be removed from or inserted into it. This position is also referred to as the release position.

In the 7th to 8th is the activator 17th shown as a single component to illustrate its structure. The protrusions 32 , 33 protrude from two side walls 34 of the activator 17th from whose distance d _{34 from} one another at least approximately a transverse extent, i.e. width d _{31 of} the longitudinal slot 31 corresponds to. Furthermore, one has the upper web 4th facing outer surface 35 of the holding section 27 a hexagonal basic shape. The outside area is concrete 35 limited by two first edges aligned parallel to one another 36 , two parallel aligned second edges 37 and two third edges aligned parallel to one another 38 . One of the first edges each 36 touches one of the second edges 37 at an edge angle α of 165 degrees. The first edges 36 are longer than the second edges 37 and the second edges 37 are longer than the third edges 38 . The second edges 37 are arranged axially offset from one another along the longitudinal axis. The third edges 38 are in the locked position perpendicular to the longitudinal axis X arranged. The first edges 36 overlap each other along the longitudinal axis in an overlap area 39 . In the 7th it can be seen that an extension L _{39 of} the overlap area 39 along the longitudinal axis X , here, in about 26 percent of an edge length L _{36 of} the respective first edges 36 corresponds to.

A distance d ₃₆ between the first two edges 36 corresponds at least approximately to the width d _{31 of} the longitudinal slot 31 . A distance d ₃₇ between the two second edges 37 is greater than the width d _{31 of} the longitudinal slot 31 and corresponds at least approximately to a clear width d _{39 of} the guide recess 28 that are at a distance from two oppositely arranged inner walls 39 the guide recess 28 corresponds to.

Around the holding section 27 of the activator 17th the guide recess from below 28 to be able to use, as in the 10 shown the activator 17th first rotated into the release position. The holding section is concrete 27 with the outer surface 35 to the upper bridge 4th pointing aligned such that the first edges 36 parallel to the longitudinal axis X are arranged. This corresponds to the perpendicular to Longitudinal axis X aligned transverse extension of the holding section 27 in the release position the distance d ₃₆ between the two first edges 36 . Then the holding section 27 from below through the longitudinal slot 31 into the guide recess 28 can be used.

Then the activator 17th , like in the 11 shown rotated 15 degrees until the second edges 37 parallel to the longitudinal axis X are aligned. The transverse extent of the holding section 27 in the locked position now corresponds to the distance d37 between the two second edges 37 . The projections abut accordingly 32 , 33 of the activator 17th laterally on the inner walls 39 the guide recess 28 at. The activator is also supported 17th over the ledges 32 , 33 down on the guide legs 29 , 30th from. In the locked position, the first edges cut 36 the longitudinal axis X with formation of the locking angle σ which, here, corresponds to 15 degrees.

The activator is in the locked position 17th continue along the longitudinal axis X freely movable. To the activator 17th along the longitudinal axis X To be able to fix continuously adjustable, are in the holding section 27 two mounting holes 40 formed with an internal thread, into each of which a set screw (not shown) is screwed. For the clamping fixation of the holding section 27 on the track 1 the set screws reach through the mounting holes 40 and press their screw ends against a floor 41 the guide recess 28 .

Furthermore, the activator 17th an intermediate section 42 on the holding section 27 with the arm 24 connects. The intermediate section 42 , of which the holding section 27 protrudes, is formed flat. The poor 24 protrudes perpendicularly from the intermediate section 42 from. The poor 42 and the holding portion 27 protrude from two opposite ends of the intermediate section 42 from and are on two opposite sides of the intermediate section 42 arranged.

In the inserted state there is an upper side 43 of the intermediate section 42 flat on one underside 44 of the outer guide leg 30th at. So one from the top 43 averted underside 45 of the intermediate section 42 flush with a bottom 46 of the inner guide leg 29 can complete is the bottom 44 of the outer guide leg 30th opposite the bottom 46 of the inner guide leg 29 reset by the thickness D. of the intermediate section 42 . In this way the intermediate section protrudes 42 not in the walkway 26th into it so that the trolleys 6th under the intermediate section 42 can drive along unhindered.

Adjacent to the holding section 27 has the intermediate section 42 two locking holes 47 with an internal thread into which two further adjusting screws (not shown) are screwed. The two locking holes 47 are on a common straight line A. arranged in the inserted state, as in the 11 shown parallel to the longitudinal axis X runs. The screwed in set screws reach through the securing holes 47 and their screw ends protrude into the longitudinal slot 31 into it. A distance d ₄₇ between the outer circumference of the respective securing hole 47 and the outer guide leg 30th is at least about 0.2 millimeters. This is how the activator is 17th additionally against rotation around the vertical axis Z secured.

The running rail 1 can be below the catwalk 8th one perpendicular from the side thigh 3 protruding further web 48 exhibit. In the one between the bridge 48 and the catwalk 8th limited space can be added in a known manner, a seal (not shown) on the door leaf 2 can apply. The bridge 48 can the running rail 1 complete at the bottom. Likewise, the one with the upper web can also be used 4th connected and parallel to the side bridge 4th arranged blind web (not shown), which can also be referred to as a screen or cover, have an intermediate space formed between two webs for a seal.
