Description

The invention relates to a sliding door fitting for a sliding door cabinet, wherein a first of at least two sliding leaves of a flushing position, in which the front side of the first sash substantially flush with the front of the second sash, via an offset position in which the front side of the first sash against the front of the second sliding leaf is offset transversely to the direction of displacement, in the direction of displacement over the second sliding sash in an open position is displaceable, with a control lever to from an initial displacement distance of the first sash in the initial phase of the opening movement or in the final phase of the closing movement of the first sliding sash to control an offset distance in the offset position or in the flush position, wherein the control lever displaceable transversely to the running rail extension on a displaceable along a running rail carriage Has carriage engaging output arm and a cooperating with a stop drive arm.

The DE 37 16 876 C2 describes a fitting for sliding doors. The fitting there is provided for a sliding door system, in which the doors are arranged in the closed state in a plane next to each other. To open a cabinet equipped with such a sliding door system, one of the doors from the flushing position must be brought into an offset position. For this purpose, the door must be displaced substantially transversely to its extension plane, so that it can be pushed from the offset position on the other door out into an open position. In the fitting described therein, a sliding holder is firmly connected to the sliding sash. This rests on a roller table, so that it can be displaced in a direction transverse to the extension direction of the track rail. To control two control levers are provided.

The EP 0195 880 also describes a sliding door fitting in which a sliding sash must be moved from a flushing position into an offset position before the sliding sash can be pushed into an open position. Here, an angle lever is provided to control the offset movement.

The DE 10 2010 016 040 describes a drive device with a toothed belt to shift a sliding door of a sliding door cabinet back and forth between an open position and a closed position.

In the prior art, the narrow sides of the sliding door wings facing each other must be chamfered so that the sliding sash placed in the offset position can be displaced past the sliding sash remaining stationary. This limits the visual appearance of the front of the cabinet.

The invention has for its object to provide a nutzsvorteilhafteren sliding door fitting.

The object is achieved by the invention specified in the claims.

First and essentially it is provided that the length of the drive arm and the length of the driven arm are each dimensioned so that the offset distance is at least twice as large as the initial displacement distance. According to this embodiment, it is possible, for example, on a displacement of about 15 mm to move the sliding sash by about 40 mm. In a preferred embodiment, the control lever is an angle lever with a pivoting lever mounted on the carcass or on the carriage. The drive arm can be half as long as the output arm. Is the angle lever on Carriage hinged, so the axis of its pivot bearing preferably passes through a slot of the carriage. The stop may be formed by a stop carrier. This can be attached at any point on the body or on a screwed onto the top floor of the carcass support profile. The attachment of the stop carrier on the body can be done by means of screws. The position of the stop carrier can be determined during assembly. For example, the sliding leaf can be brought into its closed position and secured in this position, the stop carrier on the body or support section. A development of the invention relates to a securing element. This securing element prevents the carriage from shifting in an open position of the sliding leaf relative to the carriage. In the closed position of the sliding leaf, the securing element assumes a non-operative position. In this position, the carriage can move relative to the carriage. Preferably, the securing element is acted upon by a spring. It can be brought, for example by the force of the spring after reaching the offset position of the non-operative position in the operative position. The return displacement of the securing element in the Nichtwirkstellung takes place when closing the sliding leaf, for example, characterized in that abuts a stop of the securing element on the stop carrier. The securing element is then controlled in the final phase of the closing of the sliding leaf from a securing position to a release position. The securing element can be attached to the carriage. It is preferably designed as a sliding cam. The sliding cam is displaceable parallel to the displacement direction of the carriage. The particular corpusfeste, namely sitting on the stop carrier stop, which controls the drive arm in the offset position, can form a control cam. The control cam can be designed such that the drive arm undergoes a specific movement curve during the initial displacement. For example, the control cam may be designed in such a way that at the beginning of the initial displacement the sliding sash makes a larger offset displacement per displacement path than to complete the initial shift. This has the consequence that the gap between the narrow sides of two sliding doors can occupy a minimum distance. In a preferred embodiment, the stop carrier tooth-like engages in a tooth gap formed between two output arms. The underbody is assigned a guide device. This has a hinged on the sliding leaf guide lever. Along the lower edge of the subfloor runs a guide bar. At least one, but preferably two guide rollers are supported there. There is a tax role provided. This is before the initial shift with the sliding sash closed in front of a web edge. The web edge can be bevelled. In the course of the initial displacement, the guide roller rolls off at the web edge and overflows the web edge, to then roll along the guide web, while holding the guide lever in a pivoted position.

The invention further forms a generic sliding door fitting further such that the sliding leaf can be opened or closed with a motor. For this purpose, a drive device engages the carriage in order to displace the carriage in the extension direction of the running rail. In a variant of the invention, the control lever is pivotable about a pivot bearing, which is assigned to the body stationary. The control lever should be pivoted by acting on the sliding sash. Such a transmission may be provided both on an upper guide and on a lower guide of the sliding leaf. The upper guide has a on the body, in particular attached to the ceiling plate of the cabinet running rail, along which a carriage is guided. The carriage carries a transversely displaceable to the displacement carriage on which the sliding sash is attached. In a lower guide, a guide rail may be provided to hold the sliding leaf in the sliding movement in a distance position to the second sliding sash. According to this embodiment, the displacement movement of the carriage along the running rail derived a transverse movement. In the initial phase of the opening movement, the carriage arranged displaceably on the carriage is initially displaced essentially transversely to the running-rail extension direction on the carriage. Along with this displacement, which is generated by an actuation of the pivot lever by the carriage, the sliding leaf is displaced into the offset position. This displacement is derived from a linear displacement of the carriage in the direction of extension of the running rail, so that the sliding leaf can be displaced with a drive device which is of the DE 10 2010 016 040 is described. In a lower guide the control lever is also acted upon by the sliding sash. When shifting from the offset position in the direction of the open position of the output arm is decoupled from the sliding sash. When shifting back from the open position to the offset position, the output arm is coupled to the sliding sash again. The coupling between the output arm and sliding sash is thus detachable when moving the sliding sash from the offset position into the open position. In a preferred embodiment, the end of the driven arm is designed as a fork. In the flush position or the offset position, the fork is coupled to a coupling element, for example a coupling roller of the sliding leaf. The coupling element may be arranged in the upper guide on a two carriages interconnecting traverse. On a lower guide, the coupling element may be attached to a support plate which is fixedly connected to the sliding leaf. The coupling element is in the coupling position in the fork mouth. The control lever is driven by a drive arm. The drive arm is preferably shorter than the output arm. The drive arm is at an angle to the output arm and cooperates with a stop of the carriage. In a preferred embodiment of the fitting, two drive arms are provided. A first drive arm is acted upon closing the sliding sash of a first stop of the carriage. A second drive arm is when opening the sliding sash of a second stop of the carriage applied. The stops are formed by a section of the carriage. To open the sliding leaf, the end of the drive arm slides or rolls along the stop, which moves in the extension direction of the running rail. While the carriage covers such a displacement about 10 to 15 mm in the extension direction of the running rail, the carriage is displaced about 40 mm along a guide rod of the carriage transversely to the direction of extension of the running rail. When the control lever has reached its pivot end position, an end portion of the stopper overruns the drive arm. The stop may be opposed by a control cam, which acts on the end of the drive arm in the final phase of the closing movement to displace the control lever. This is done after the coupling element has reached its coupling position to the output arm, so that the sliding leaf is controlled by the offset position in the flushing position. Stop and control cam can also be formed by wall sections of a control channel or a control slot. It is preferably provided a spring element which supports the control lever in its pivotal displacement from the closed position to the offset position. With this spring element, the control lever is also held in a Einfangstellung in which the coupling element retracts when closing the sliding sash in the fork. In a further development of the invention, a securing element is provided in the upper guide, which prevents the carriage moves in an operating position of the sliding sash between offset position and open position relative to the carriage. In this fuse element may be a locking pin, which passes through an opening of the running rail in the flush position. In the offset position and in any intermediate position between offset position and open position, the end of the pin is in front of a wall, for example, the running rail. As a result, the sliding sash in which the sliding sash is fixed can not be displaced transversely to the running-rail extension direction. Such a transverse displacement is possible only from the offset position, since then the pin in the

Opening the wall can occur. A driver with which the carriage can be displaced in the extension direction of the running rail can be driven by a toothed belt drive, as already cited above DE 10 2010 016 040 disclosed. Also, a lower guide may have a securing element. It may be one or more leadership roles that are firmly connected to the sliding panel at the bottom of the sliding sash, for example, are supported by a support plate. To one of these guide rollers correspond one or more guide rails, which may, for example, be L-profiles. The guide rails are firmly connected to the underbody of the body. The control lever is preferably pivotally mounted on a base plate which is screwed firmly on the top floor or under the bottom of a cabinet body. The carriage is preferably guided between two mutually parallel rails. In this case, the carriage can be moved between the two rails. The control lever is located between the two rails, the drive arm is directed away from the pivot bearing from the sliding sash. The output arm extends essentially in the direction of travel rail extension. The two drive arms extend transversely thereto. In principle, it is sufficient if only one drive arm is provided, on which a stop engages when opening the sliding leaf, which is overrun when leaving the offset position. When closing the sliding leaf engages on this drive arm another stop, which may also have a control cam, to pivot to the control lever. In one embodiment of the invention it is provided that each of the two sliding sash each pair of carriages can be assigned. The total of four carriages can run in the same rails. So that the two sliding sash can be pushed almost completely over each other, the two carriages each sit only in the region of a horizontal half of each sliding sash. While a carriage, for example, sits on the edge of the sliding sash, the second carriage sits approximately in the middle of the sliding sash. The carriages are arranged on the respectively facing away from each other halves of the sliding sash so that the sliding sash can almost completely overlap in an open position. The two carriages, which are assigned to the respective sliding leaf, are preferably assigned to the respectively halves of the wing facing away from one another. For example, the two carriages of the left sliding sash lie on the left half of the upper peripheral edge and the two carriages of the right sash on the right half of the upper peripheral edge. As a result of this embodiment, the sliding sash can optionally be pushed completely over each other.

The sliding door fitting is used on sliding door cabinets, for example. Bedroom cabinets, living room cabinets but also kitchen cabinets. For large, heavy sliding panels several carriages are used. For smaller, lighter sliding sashes, for example on kitchen cabinets, it is sufficient if the sliding sash hangs on a carriage. The track, which is mounted on the front edge of the top floor, can perform a shape-stabilizing function. It can have several horizontal webs. By means of a substantially rectangular hollow chamber, the running rail is stabilized against bending. The lower guide may consist of a guide channel, which consists of the space between two mutually parallel webs. The channel can form at the beginning of the front edge of the body obliquely rearwardly channel portion in the form of, for example, a bag. The pocket walls are inclined. In this bag is in the closed position a tax role. It may be provided a spring which loads a guide lever, so that the control roller is subjected to force in the pocket pulled. The invention relates in addition to the aforementioned development of the prior art and those sliding door fittings of the generic type, which is further developed with the characteristics of a single subclaim.

That in the FIGS. 1 to 13 illustrated embodiment shows a sliding door cabinet with two sliding leaves 21, 21 'and a topsoil 22 to which two rails 4 are attached. In the first embodiment, only one sliding leaf 21 can be brought from a closed position into an offset position by means of the sliding door fitting according to the invention, in the the sliding wing 21 brought into the offset position can be pushed over the other sliding leaf 21 'into an open position. In order to open the second sliding leaf 21 ', the sliding leaf 21 must first of the in Fig. 1 Flattening position shown are brought into an offset position. Then the sliding leaf 21 'can be displaced under the sliding leaf 21.

In the in the Fig. 14 illustrated embodiment, both sliding sash 21, 21 'in each case by a flushing position in an offset position can be brought and in the offset position on each of the other sliding sash 21', 21 displaced. Each of the two sliding leaves 21, 21 'is displaceable with a drive device, as shown in the DE 10 2010 016 040 is shown. The disclosure of this document is therefore incorporated in full in this application.

In the FIGS. 1 to 12 the different functional positions of the upper guide are shown. The two arranged on the top floor 22 rails 4 have a C-profile. From the Fig. 5 it can be seen that the C-shaped profile openings of the running rail 4 face each other. Rollers 18 of a carriage 1 run in the profile openings of the running rail 4. The rollers 18 are carried by roller carriers 17, which are connected to one another by means of a guide rod 19. The guide rod 19 extends in a direction transverse to the extension direction of the running rail 4, which extends in the direction of displacement of the sliding leaf 21, 21 '. In the first embodiment, two carriages 1 are attached to only one of the two sliding panels 21. At the in Fig. 14 illustrated embodiment, two carriages 1 are attached to two sliding panels 21, 21 'in each case. The two carriages are each mounted on only one half of the sliding leaf 21, 21 ', so that they can run in the same rails 4. They are attached to the halves facing away from each other on the sliding leaf 21, 21 '. From the Fig. 5 It can be seen that the non-displaceable sliding leaf 21 'is slidably guided by a roller 28 on a separate rail section.

On the guide rod 19, which is double in the embodiment, a carriage 2 is slidably mounted. On slide 2, the sliding wing 21 is attached via a bracket. The carriage 2 forms a guide block 20, which is penetrated by the two guide rods 19.

A section 11 of the roller carrier 17 forms a first stop 12 and a second stop 13. The second stop 13 forms the wall of a capture opening whose other wall 14 forms a control cam.

On one of the two carriages 1 is a securing element 26 in the form of a pin. In the closed position of the sliding sash 21 (FIG. Fig. 4 ) passes through the locking pin 26 has an opening 27 of the bottom of the C-profile of the running rail 4. The locking pin 26 has a length such that it in the in the Fig. 8 shown offset position is completely pulled out of the opening 27. He prevents the carriage 2, for example, in the in Fig. 10 shown operating position can be displaced so far in the direction of the body of the sliding door cabinet that brought into the offset position sliding sash 21 can abut against the not placed in the offset position sliding sash 21 '. He thus reduces the displacement path of the carriage 2 relative to the carriage. 1

On the top floor 22 of the cabinet, a base plate 10 is attached. This base plate 10 is firmly connected to the body of the cabinet. On the base plate 10, a control lever 5 is pivotally mounted about a pivot bearing 9. The control lever 5 has a short drive arm 7, which extends substantially transversely to the direction of displacement of the carriage 1. The control lever 5 also has an approximately four times as long output arm 6, which extends substantially in the direction of displacement of the carriage 1. At its free end, the output arm 6 has a fork 6 '.

Between the first drive arm 7 and the fork 6 'is a second drive arm 8. Both drive arms 7, 8 have at their ends rollers 7', 8 '. The roller 7 'cooperates with the stop 12. The roller 8 'is located in the receiving opening between the stop 13 and cam 14th

It is a spring element 16, for example. Provided in the form of an acted upon by a compression spring plunger, which provides the control lever 5 in a in the Fig. 10 shown Einfangstellung holds in which the control lever 5 is supported on an end stop 15 of the base plate 10.

Parallel to the running rail 4, a drive device 24 extends with a toothed belt, which can displace a driver 23 along the running rail 4. The driver 23 is connected to the carriage 1.

The two carriages 1 are connected to one another by a cross-member 3 which carries a coupling element 25, which in the exemplary embodiment is formed by a roller.

The bottom guide, in the FIGS. 15 to 20 He has a driven arm 6 and two drive arms 7, 8. The stop 13 and the control cam 14 are here by an angled End portion of a guide channel 29 is formed. The guide channel 29 is supported by a support plate 30 which is fixedly connected to the sliding leaf 21. The end of the drive arm 7 'carries a roller of a stop 12, of an angled portion of the Support plate 30 is formed, can be acted upon. The guide channel 29 forms together with the stop 13 and the control cam 14 a control slot, so that the stop 13 and the control cam 14 are formed by slot walls.

The coupling element 25 is also designed here as a role. The roller 25 is supported by a support plate 31 which is fixedly connected to the sliding leaf 21. The support plate 31 carries further guide rollers 32 which cooperate with the opening of the sliding leaf 21 with guide rails 33 which are fixed to the underside of the subfloor. When the sliding leaf is opened, the guide rollers 32 rest against the guide rails 33 in such a way that the sliding leaf 21 can not shift in the transverse direction to the displacement direction.

By means of a spring element 16, which may be a tensioned compression spring, the control lever 5 is acted upon by an end stop 15 when the sliding leaf 21 is in its open position.

The upper and the lower guide each have an identically designed and identically dimensioned control lever. 5

The fitting has the following function:

In the in the FIGS. 4 or 17 illustrated operating position, the two sliding leaves 21, 21 'in a flush position to each other. Their outward facing surfaces lie in a common plane. In this position, a coupling element 25 is in the form of a roller in the mouth of the fork 6 '. The end of the drive arm 7 is located on the stop 12 and the end 8 'of the drive arm 8 between stop 13 and cam 14. The spring element 16 is stretched. If the carriage 1, starting from the in Fig. 4 or 17 shown closed position to the right in the in Fig. 6 or displaced shown operating position, so the stopper 13 exerts a torque on the control lever 5 in the clockwise direction, which has the consequence that the control lever 5 and thus also the output arm 6 pivots. Along with the pivoting of the output arm 6, the coupling element 25 is displaced substantially transversely to the direction of displacement of the two carriages 1, so that the carriages 2 of the upper guide shift along the guide rods 19. Along with the pivoting of the output arm 6, the coupling element 25 is displaced substantially transversely to the running direction of the two carriages, so that the carriage 2 of the upper guide is displaced along the guide rod 19. The pivoting fork 6 'acts both on the underside and on the upper side of the sliding leaf 21 in one direction in front of the other sliding leaf 21.

In the course of further linear displacement of the carriage 1 in the FIGS. 7 and 8th achieved intermediate positions in which the end 7 'of the drive arm 7 from the stop 12 triggers. In the final phase of the shift of the sash 21 from the closed position into the offset position, the end 13 'of the stopper 13 overflows the end of the drive arm 8 formed by a roller 8'. The linear further displacement of the carriage 1 then results in that the coupling roller 25 Fork 6 'leaves.

In the course of this initial transverse displacement of the carriage 2 relative to the carriage 1, the locking pin 26 emerges from the opening 27.

In the lower guide over the end of the drive arm 8 forming roller 8 'also overflows the stop 13 and then passes through the guide channel 29. In the course of this linear displacement, the guide rollers 32 enter the guide rails 33 a. The sliding wing 21 can thus into the in Fig. 10 shown open position to be shifted. In this position, the distance position of the sliding leaf 21 relative to the second sliding leaf 21 'on the one hand by means of the locking pin 26 and on the other hand held by means of the guide rails 33 cooperating with the guide roller 32.

When closing the sliding leaf 21 occurs in the final phase of the linear displacement of the carriage 1, the coupling element 25 again in the fork 6 '. The end 7 'of the drive arm 7 and the end 8' of the drive arm 8 is acted upon by a stop 12 and the control cam 14. This has the consequence that on the control lever 5, a torque is applied. The latter has the consequence that the control lever 5 pivots in the counterclockwise direction and displaces the carriage 2 on the carriage 1 or controls the lower portion of the sliding leaf 21 in the direction of the body. This has the consequence that the sliding leaf 21 is displaced from the offset position back into the closed position. The locking pin 26 can immerse again in the opening 27.

In the in the Fig. 14 In the illustrated embodiment, the sliding leaf 21 'can be displaced in an analogous manner from a closed position initially into an offset position and then into an open position, in which case the sliding leaf 21' overflows the sliding leaf 21.

The Fig. 21 shows similar to the Fig. 14 a sliding door cabinet with two approximately identically designed sliding leaves 21, 21 ', which are fastened with an upper fitting to a top floor 22 of the body and with a lower fitting to a subfloor.

The in the FIGS. 22 to 27 and 31 to 33 illustrated upper fitting has a rail 4, which forms a running rail, which is located at the front edge of the upper floor 22. To the rear offset to parallel to the running rail 4, a further, a support profile 33 forming profile rail. The running rail 4 has a guide rib on which a plurality of rollers 18 of a carriage 1 can roll. The carriage 1 has a guide profile 19 and at the other end of the guide profile 19 further rollers 31, 31 ', with which the carriage 1 is supported on two legs of the support profile 33. The two rollers 31, 31 'extend in a C-shaped opening. The profile rib of the running rail 4, on which the roller 18 runs, is located in a U-profile. A roller 18 'is supported on the tread rib opposite profile leg. The running rail 4 is formed by a profile body, which is mounted along the front peripheral edge of the topsoil, resting on the topsoil. The running rail 4 has a plurality of horizontal webs, which form the running rail 4 a high bending stiffness. In particular, the profile forming the running rail 4 forms a hollow chamber 40. This prevents that bends due to the weight of the sliding sash of the topsoil.

The track 4 also has an upwardly projecting from the top floor 22 web 30. On the two web walls run horizontal rollers 29, which serve to stabilize. These stabilizing rollers 29 are located below the guide profile 19th

On the carriage 1, a carriage 2 is mounted displaceably transversely to the direction of extension of the running rail 4 and the support section 3. For this purpose serve rollers 28 which are mounted as guide rollers on a guide block 20 of the carriage 2 and can roll on profile webs of the guide profile 19.

From the FIGS. 22 to 27 it can be seen that the carriage 2 has a horizontal plate which forms a mounting bracket 48 to which the rear broad side of the sliding leaf 21 is attached.

The upper side of the mounting bracket 48 has a swept by a control lever 5 slot 27. The pivot bearing 9, by which the control lever 5 is pivotable in a horizontal plane, is assigned to the carriage 1 in a stationary manner. The control lever 5 has two shorter drive arms 7, 8 and at least twice as long a drive arm 6. About an elongated bearing eye and a pin 49 disposed therein, the end of the output arm 6 is fixedly connected to the carriage 2. The drive arm 8 is formed by a cam which protrudes from the output arm 6. The drive arm 7 protrudes from the pivot bearing 9 approximately at right angles to the output arm 6.

Between the ends of the drive arm 7 and drive arm 8, a gap extends. In this gap engages an end portion of a stop element 12. The stop element 12 is a tongue-like stop carrier, which is fastened by means of fastening screws on the support section 33 and projects over the base plate of the carriage 2. The attachment side of the stop member 12 opposite free end of the stop carrier 12 forms a stop 14 which is formed as a sloping edge and which cooperates with the drive arm 7. To this end, the free end of the stop carrier 12 forms a control cam 13, which cooperates with a counter-control cam of the drive arm 8.

An angular securing element 26 is provided. The securing element 26 is attached to the carriage 1 transversely to the direction of displacement of the carriage 2. The displacement direction of the securing element 26 is thus parallel to the direction of displacement of the carriage 1 along the running rail 4. A parallel to the direction of displacement of the securing element 26 extending leg has a longitudinal slot 38, engage by the fastening screws with which the securing element 26 is attached to the carriage 1. By means of a tension spring 37 is a transverse to the direction of displacement of the securing element 26 extending leg against the carriage 2 is applied. The end of this leg forms a support shoulder 35. The securing element 26 also forms a stop cam 34, which cooperates with the stop element 12.

The carriage 1 has two mutually parallel guide profiles 19. At one fixed end of the tension spring 37 is attached. The other guide profile 19 carries the securing element 26. Both guide profiles 19 each have stabilizing rollers 29. The two guide profiles 19 are connected to each other by means of roller carriers 17 which carry the rollers 18, 18 '. Further roller carriers carry the rollers 31.

The guide device fastened to the underbody 39 has a guide rail with a guide web 43. A guide lever 40 is articulated about an axis of rotation 47 at a mounting bracket 46, which is fastened to the rear broad side of the sliding leaf 21. The guide lever 40 carries at its free end two guide rollers 41, 42 which can roll 43 at the two sides facing away broad sides of the guide web. On the guide lever 40 also sits a control roller 45, which lies in the closed position of the sliding leaf 41 in front of a web edge 44 of the web 43. The web edge 44 is formed as a slope. In the open position ( FIG. 30 ) rolls the control roller 45 over a broad side of the web 43 and thus prevents pivoting back of the guide lever 40 in the in Fig. 28 illustrated closed position.

The functionality of the fitting is the following:

In the in the Figures 22 and 28 illustrated closed position are the front sides of the sliding sash 21, 21 'flush with each other. The mutually facing narrow edges of the sliding sash 21, 21 'are formed dull and are approximately at a distance of 10 to 15 mm. The inclined stop 14 is located on a stop edge of the drive arm 7. An edge of the control cam of the drive arm 8 abuts against an edge region of the control cam 13. The control roller 45 is located in front of the web edge 44.

Is starting from this in the Figures 22 and 28 shown position of the sliding leaf 21 in the displacement direction, that is acted upon in the direction of extension of the running rail 4, the control cam of the drive arm 8 slides on the control cam 13 along until the in the FIGS. 23 to 29 shown operating position is reached. The sliding leaf 21 has been spaced from the body 22 by a multiple of its displacement movement. He has moved only by 6 mm on the sliding leaf 21 ', but removed by 24 mm from the body 22.

If the sliding panel 21 continues in the in Fig. 24 displaced shown operating position, the sliding sash has a total of about 10 mm on the sliding sash 21 'to move, but a total of about 36 mm away from the body 22.

A further shift to the in the Figures 25 or 30 shown operating position leads to a complete offset position after a Initialverschiebestrecke of 15 mm. The offset distance here is 40 mm. During this displacement, the control roller 45 has rolled over the oblique web edge 44 and is now on the broad side of the web 34, so that the guide lever 40 can not swing back. The control cam 8 has overflowed the cam 13.

During the displacement of the carriage 2 along the carriage 1, the broad side of the base plate of the carriage 2 has moved along the peripheral edge of the transverse leg of the securing element 26 until the in Fig. 25 shown operating position is reached, in which the spring 37, the securing element 26 in the Relocated securing position in which the support shoulder 35 of the securing element 26, the peripheral edge 36 of the carriage 2 engages behind, so that the carriage 2 is secured in its offset position relative to the carriage 1.

In this secure offset position of the sliding sash over the intermediate position according to Fig. 26 be brought into the full open position in which the sliding leaf 21 is above the sliding sash 21 '.

Upon a return displacement of the sliding leaf 21 from the open position in the direction of the closed position, the drive arm 8 passes the free end of the stop element 12 until the drive arm 7 abuts against the stop 14. Previously, however, the stop cam 34 has entered against a peripheral edge of the stop element 12, so that the securing element 26 is displaced relative to the carriage 1, wherein the spring 37 is tensioned. In this case, the support shoulder 35 is displaced from the area of action of the peripheral edge 36. By acting on the drive arm 7 by the stop 14 of the stationary stop carrier 22, the control lever 5 rotates about its stationary on the carriage 1 fixed pivot bearing 9, so that the output arm 6 moves the carriage 2 back into the closed position of the sliding leaf 21.

The base plate of the carriage 2 has a slot 27 through which engages the axis of the pivot bearing 9.

According to the lengths of the levers 7, 8 and 6, the control lever 5 derives from a displacement movement at least twice as large offset movement transversely to the displacement direction. As a result of the dimensioning of the arms of the control lever, the mutually facing narrow edges of the sliding sash 21, 21 'need not be beveled, so that when moving the sliding sash moving past the non-moving sliding sash can pass. The narrow edges can be made blunt with the dimensioning according to the invention be and yet be arranged relatively close to each other, so that the gap width of the gap between the two sliding leaves is minimized in the closed position.

The FIGS. 34 to 37 show an alternative of a lower guide. On the underside of the lower floor 39, a two webs 43, 43 'having profiled rail is mounted. The two webs 43, 43 ', which run parallel to the front edge of the subfloor 39, form with their intermediate space a guide channel for a guide roller 41 and a control roller 45.

The control roller 45 and the guide roller 41 are disposed at both ends of a guide lever 40. The guide lever 40 is connected to the rotation axis 47, which coincides with the axis of rotation of the control roller 45, at a fixedly connected to the sliding panel 21 mounting bracket 46.

On a boom which protrudes transversely to the extension direction of the guide lever 40, a tension spring 52 engages, which exerts a torque on the guide lever 40. At the free end of the guide lever 40, the guide roller 41 sits.

In the closed position of the sash, which in the Figures 34 and 36 is shown, the guide roller 41 is located in a straight-line section of between the webs 43, 43 'arranged channel. The beginning of the channel is formed by a rearwardly projecting from the front edge of the subfloor pocket 52. The channel walls, ie the mutually facing surfaces of the webs 43, 43 'go to form a curvature or slope in a channel beginning section (pocket 52). In the closed position, the control roller 45 is located in the end portion of the pocket 52, so that the sliding wing 21 rests its position approximated to the carcass.

If the sliding sash 21 of the in the Figures 34 and 36 placed closed position shifted in the direction of the open position, so occurs in the course of the initial shift (see. Figures 35 and 37 ) the control roller 45 out of the pocket 52. Along with this shift, the sliding panel 21 is in the in the Figures 35 and 36 shown offset position brought. During this shift, the tension spring 51 is tensioned.

When the sliding leaf 21 is closed again, the tensioned spring 51 pulls the control roller 45 back into the pocket 52.
