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 the activator.

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, the holding section can be rotated 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. Preferably the second edges are 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 or touch one of the second edges at an edge angle of more than 150 degrees and less than 175 degrees. 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 an adjusting screw can also be referred to as 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 space below the outer guide leg that can be used can, in order to arrange the intermediate section as flat as possible on the underside of the upper web, 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 end of the screw protrudes from an upper side of the intermediate section in front 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 hits 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 made in the driver be formed, wherein the nose in the disengaged position is out of engagement with the recess and in the engaged position in engagement with the recess. 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 Figures 1 to 11 there is shown a sliding door assembly in accordance with an embodiment of the present invention. The Figures 1 to 11 are described collectively below. The sliding door arrangement has a running rail 1 and a door leaf 2 which is guided displaceably along a longitudinal axis X defined by the running rail 1. The door leaf 2 can be parallel to a plane E, which is formed by the longitudinal axis X and a vertical axis Z aligned perpendicular to the longitudinal axis X, in the running rail 1, with a view of the Figure 1 , both to the left and to the right.

In the Figures 1 to 6 As well as 10 and 11, a Cartesian coordinate system with the longitudinal axis X, the transverse axis Y and a vertical axis Z is shown to illustrate the alignment of the sliding door arrangement in space. In the assembled state, in which the sliding door arrangement is attached to a stationary component, in particular the building wall, via the running rail 1, the vertical axis Z runs 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 web 3 and an upper web 4. The upper web 4 is arranged perpendicular to the side web 3 and extends along a transverse axis Y. Holes (not shown) can be formed in the side web 3 in order to screw the running rail 1 to a building wall (not shown) above a wall opening. Furthermore, the running rail 1 can have a cover web (not shown) which, for optical and safety reasons, can be attached to the upper web 4 from the outside and fastened to it. For this purpose, a longitudinal groove 5 can be formed on the upper web 4, in which, for example, a tongue formed on the cover web can be inserted, other types of connection also being conceivable and possible. Cover caps (not shown) can be placed on both longitudinal ends of the longitudinal rail 1.

In order to guide the door leaf 2 displaceably in the running rail 1, the sliding door arrangement comprises two carriages 6 spaced apart from one another, on which the door leaf 2 is fixed in a suspended manner. The carriages 6 are each supported by a roller 7 on a catwalk 8 protruding from the side web 3. The catwalk 8 has, here, a channel-like recess 9 which extends along the longitudinal axis X and in which the rollers 7 of the two carriages 6 are movably guided. The two carriages 6 can each have two side parts 10 ', 10 "which are screwed to one another by means of screws 11. Below the screws 11, the carriages 6 each have a clamping section 12 in which the door leaf 2 is suspended Side parts 10 ', 10 "of the respective carriage 6 in the clamping section 12 are spaced apart from one another in the transverse direction Y and hold an upper edge region of the door leaf 2 by clamping between them.

Furthermore, two dampers 13 are provided in order to brake the door leaf 2 in a controlled manner when the door leaf 2 is moved laterally to the left and to the right shortly before the respective end position is reached. The two dampers 13 are, here, constructed identically. The two dampers 13 are arranged between the two carriages 6, one of the two dampers 13 being attached to each of the carriages 6. Specifically, the respective damper 13 is attached at the end to the associated carriage 6 by means of a holder 14. Furthermore, the respective damper 13 is supported at its free end via a spacer 15 on the door leaf 2. In relation to the longitudinal axis X between the spacer 15 and the holder 14 of the respective damper 13, the latter has a driver 16 which can engage with one of two activators 17 fixed on the running rail 1. For controlled braking, a first of the two activators 17 is fixed shortly before the left end of the running rail 1 and a second of the two activators 17 is fixed shortly before the right end of the running rail 1. In the Figures 1 to 3 partial sections of the sliding door arrangement around the left end of the running rail 1 are shown by way of example. For the right end position (not shown), however, the comments on the left end position apply in an analogous manner.

In Figure 6 the damper 13 is shown as a single component to illustrate its structure. The driver 16 of the respective damper 13 is guided in a guide track 18 along the longitudinal axis X. The respective guide track 18 is arranged on a side of the damper 13 facing away from the side web 3 and has two L-shaped elongated holes 19 arranged one above the other along the vertical axis Z. On the respective driver 16, two of a total of four bolts 20 are arranged on two sides facing away from one another and engage in the two elongated holes 19 arranged one above the other to guide the respective driver 16. Furthermore, the respective damper 13 has an energy storage device 21 which acts on the associated driver 16 with force in order to brake the movement of the driver 16 in a controlled manner when the door leaf 2 approaches the associated end position.

To interact with the associated activator 17, the respective driver 16 has a recess 22 designed as a groove. The recess 22 extends along the vertical axis Z completely over the driver 16. Thus the recess 22 is designed to be open both upwards and downwards and also on a side facing away from the side web 3.

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

The activator 17 has an arm 24 which protrudes from the underside 23 of the upper web 4 and is arranged on a side of the carriage 6 opposite the side web 3, or between the cover web and the carriage 6. The arm 24 is aligned parallel to the side web 3. Looking at the activator 17 in the transverse direction Y, it can be seen that the arm 24 has the shape of a triangle, the tip of the triangle pointing downwards. A coupling element 25, which interacts with the driver 16, is formed on the arm 24. In the Figure 4 FIG. 13 is a sectional view taken along that of FIG Figure 1 shown line IV-IV. It can be seen that the coupling element 25 is in engagement with the recess 22 of the driver 16. The coupling element 25 is designed as a nose which protrudes from an inside of the arm 24 facing the carriage 6 towards the side web 3. The coupling element 25 extends over approximately 90 percent of a height H of a walkway 26, the height of which is limited between the walkway 8 and the upper bridge 4. To clarify the structure, the Figure 5 Another cross-sectional view of the sliding door arrangement is shown, the carriage 6 and the door leaf 2 fixed thereon being not shown for the sake of clarity.

The coupling element 25 is in a disengaged position out of engagement with the driver 16 and in an engaged position in engagement with the driver 16. In the Figure 2 the disengaged position is shown. The driver 16 is in its parking position, in which two of the bolts 20 of the driver 16 engage in the short L-web of the L-shaped elongated hole 19, whereby the driver 16 is tilted about the vertical axis Z towards the associated coupling element 25. The driver 16 is biased into the parking position by the associated energy storage device 21. In the Figures 3 and 4th the engaged position is shown. It can be seen that the coupling element 25 engages in the recess 22 of the driver 16. By sliding the door leaf 2, with a view of the Figure 3 , the driver 16 is moved to the left against the direction of force of the energy storage device 21, the door leaf 2 being braked in a controlled manner.

Furthermore, the activator 17 has a holding section 27 which is inserted in a guide recess 28 formed on the underside 23 of the upper web 4. The guide recess 28 runs along the longitudinal axis X and extends over the entire longitudinal extent of the running rail 1. Towards the bottom, the guide recess 28 is delimited by an inner guide leg 29 closest to the side web 3 and an outer guide leg 30. A longitudinal slot 31, which extends along the longitudinal axis X, is formed between the two guide legs 29, 30.

The holding section 27 can be inserted into the guide recess 28 from below. For this purpose, two projections 32, 33 are formed in the holding section 27 of the activator 17, which in a blocking position engage behind the guide legs 29, 30. In the Figures 1 to 5 and 11 the activator 17 is shown in the locked position. In FIG. 10, the projections 32, 33 are aligned in such a way that they overlap with the longitudinal slot 31. The activator 17 is then released with respect to the guide recess 28 and can be removed therefrom or inserted into it. This position is also referred to as the release position.

In the Figures 7 to 8 the activator 17 is shown as a single component to illustrate its structure. The projections 32, 33 protrude from two side walls 34 of the activator 17, the distance d _{34 of which from} one another corresponds at least approximately to a transverse extension, that is to say the width d _{31 of} the longitudinal slot 31. Furthermore, an outer surface 35 of the holding section 27 facing the upper web 4 has a hexagonal basic shape. Specifically, the outer surface 35 is delimited by two parallel first edges 36, two parallel second edges 37 and two parallel third edges 38. Each of the first edges 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 along the longitudinal axis arranged axially offset from one another. The third edges 38 are arranged perpendicular to the longitudinal axis X in the blocking position. The first edges 36 overlap one another along the longitudinal axis in an overlap region 39. In FIG Figure 7 it can be seen that an extension L _{39 of} the overlap region 39 along the longitudinal axis X, here, _{corresponds to approximately 26 percent of an edge length L 36 of} the respective first edges 36.

A distance d ₃₆ between the two first 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, which corresponds to a distance between two oppositely arranged inner walls 39 of the guide recess 28.

In order to be able to insert the guide recess 28 from below the holding section 27 of the activator 17, as in FIG Figure 10 shown, the activator 17 initially rotated into the release position. Specifically, the holding section 27 is aligned with the outer surface 35 facing the upper web 4 in such a way that the first edges 36 are arranged parallel to the longitudinal axis X. The transverse extension of the holding section 27, which is perpendicular to the longitudinal axis X, corresponds to the distance d ₃₆ between the two first edges 36 in the release position. The holding section 27 can then be inserted from below through the longitudinal slot 31 into the guide recess 28.

Then the activator 17, as in Figure 11 shown rotated 15 degrees until the second edges 37 are aligned parallel to the longitudinal axis X. The transverse extension of the holding section 27 in the blocking position now corresponds to the distance d37 between the two second edges 37. The projections 32, 33 of the activator 17 accordingly abut the inner walls 39 of the guide recess 28 laterally. Furthermore, the activator 17 is supported on the guide legs 29, 30 in a downward direction via the projections 32, 33. In the blocking position, the first edges 36 intersect the longitudinal axis X, forming the blocking angle σ, which, here, corresponds to 15 degrees.

In the locked position, the activator 17 can still be freely displaced along the longitudinal axis X. In order to be able to fix the activator 17 in a continuously adjustable manner along the longitudinal axis X, two fastening bores 40 with internal threads are formed in the holding section 27, into each of which a set screw (not shown) is screwed. For the clamping fixation of the holding section 27 on the running rail 1, the adjusting screws reach through the fastening bores 40 and press with their screw ends against a bottom 41 of the guide recess 28.

Furthermore, the activator 17 has an intermediate section 42 which connects the holding section 27 to the arm 24. The intermediate section 42, from which the holding section 27 protrudes, is flat. The arm 24 protrudes perpendicularly from the intermediate section 42. The arm 42 and the holding section 27 protrude from two opposite ends of the intermediate section 42 and are arranged on two sides of the intermediate section 42 facing away from one another.

In the inserted state, an upper side 43 of the intermediate section 42 rests flat against an underside 44 of the outer guide leg 30. So that an underside 45 of the intermediate section 42 facing away from the upper side 43 can end flush with an underside 46 of the inner guide leg 29, the lower side 44 of the outer guide leg 30 is set back from the underside 46 of the inner guide leg 29 by the thickness D of the intermediate section 42. In this way, the intermediate section 42 does not protrude into the path 26, so that the carriages 6 can travel along underneath the intermediate section 42 without hindrance.

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

The running rail 1 can have a further web 48 projecting perpendicularly from the side limb 3 below the catwalk 8. In the intermediate space delimited between the web 48 and the catwalk 8, a seal (not shown) can be accommodated in a manner known per se, which can rest against the door leaf 2. The web 48 can close the running rail 1 at the bottom. Likewise, the cover web (not shown) connected to the upper web 4 and arranged parallel to the side web 4, which can also be referred to as a diaphragm or cover, can have an interspace formed between two webs for a seal.
