Description

The present invention relates to a running rail for a lift and slide element according to the preamble of claim 1, as the type of essentially from FR 2 980 510 A3 is known.

The present invention also relates to a lift-and-slide element, in particular a lift-and-slide door or a lift-and-slide window, with a running rail that defines a running track, and a sash that can be moved on the running track by means of a running roller arrangement, the sash between a lowered fixing position and a raised travel position is adjustable.

Such lift-and-slide elements are becoming increasingly common, for example in the form of large patio doors or windows, but can also be used in the form of sliding walls to temporarily separate certain areas of a room. In general, with such lift-and-slide elements, the running rail is arranged below the sash, in particular on the floor, with a number of rollers arranged on the underside of the sash rolling directly on the running track of the lower running rail. The running rail can be designed as a threshold or be integrated into a frame. In principle, the roller arrangement could also be arranged on the upper side of the wing, with the rollers of the roller arrangement rolling on a hanging rail. In such a configuration, the running rail is arranged above the wing.

It can be provided that the underside of the wing sits on the track in the lowered fixing position, preferably immovably. In contrast For example, the underside of the wing may be spaced from the track by an air gap when the wing is in the raised travel position. Due to the air gap formed, the wing can be moved by means of the rollers when it is in the raised travel position. However, it is not mandatory for the underside of the wing to sit on the track in the lowered fixing position. That is, the wing can be carried in principle by the rollers in the lowered position, the fixation z. B. is caused by a blockage of the rollers. Likewise, it is not mandatory for the air gap to be recognizable as such from the outside. For example, the air gap could run like a labyrinth.

With conventional lift and slide elements, the sash is raised and lowered by operating a handle that is coupled to a lifting mechanism via a connecting rod gear. Many users find this annoying. In particular, in the case of large-area and correspondingly heavy wings, a considerable expenditure of force is also required in order to accomplish the manual lifting. For this reason, the handles in common Lift&Slide elements are often designed as relatively long levers, which spoil the appearance of the sash.

The DE 197 25 355 A1 discloses a sliding door whose door leaf is suspended from a support rail. An end area of the support rail on the closing edge side is lowered compared to the remaining area.

In the CH 408 697 A discloses a lift and slide window, the sash of which can be moved along a running rail by means of an arrangement of three running rollers. Indentations are provided in the running rail, into which the running rollers can move.

It is an object of the invention to simplify the raising and lowering of the sash in lift and slide elements.

The object is achieved by a running rail with the features of claim 1.

The running track of a running rail according to the invention has at least one recess into which a running roller of the running roller arrangement can be moved into the lowered fixing position while lowering the wing.

The indentation causes a displacement movement of the wing to be partially converted into a lowering movement of the wing. This enables the sash to be automatically lowered without operating a handle or the like. Since the roller can be extended out of the recess again while the wing is raised, the invention also enables the wing to be raised automatically without operating a handle or the like. The user therefore only has to move the wing into the position provided for fixing, for example into the closed position, in order to automatically bring about a lowering of the wing. With a lift and slide element according to the invention, it is therefore not absolutely necessary to provide a handle or the like on the sash. However, a handle can be provided on the wing to facilitate pushing. Such a handle does not have to be coupled to a connecting rod mechanism and can be designed accordingly in a simple manner.

By providing a suitable indentation a self raising and lowering wing can be made possible, which wing can in principle be a conventional wing. The position and the shape of the depression only have to be adapted to the roller arrangement of a given wing such as e.g. B. be adapted to a standard wing.

The running track of a running rail according to the invention has at least one ramp section, via which a roller of the roller arrangement can be extended out of the recess while raising the wing into the raised travel position and/or can be moved into the recess while lowering the wing into the lowered fixing position. The ramp section prevents the wing from dropping abruptly when the roller enters the recess. When the roller is extended from the recess, the ramp section partially converts the sliding movement of the wing into a lifting movement. By designing the ramp section appropriately, for example by providing a relatively long and slightly inclined ramp section, the effort required for lifting can be reduced.

According to the invention, at least one flap protruding into the depression is provided, which can be pivoted between a horizontal position, in which the flap covers the depression, and an inclined position and forms the at least one ramp section in the inclined position. The pivoting into the inclined position can be effected in an advantageous manner by the weight of the wing when the roller drives onto the flap. In this embodiment, the ramp section is therefore only provided as needed to a certain extent.

Provision is preferably made for the wing to be supported on the track in the raised travel position by at least two spaced-apart rollers or carriages having rollers, and for the track to have at least two correspondingly spaced depressions into which the at least two rollers or carriages can be moved at the same time. Due to the simultaneous retraction of the two supporting rollers or carriages, the sash is lowered without horizontal tilting, i.e. with the underside always parallel to the ground. By simultaneously extending the two supporting Rollers or carriages from the recess of the sash is raised in a corresponding manner without horizontal tilting.

According to a special embodiment, in the horizontal position, the flap covers the depression at least essentially completely. The indentation is therefore not visible to a user when the leaf is open, which gives the running rail an attractive appearance. In addition, the covering flap protects the recess from penetrating dirt.

The flap is preferably biased into the horizontal position by a spring device. In this way it is ensured that the depression is always partially or completely covered when the leaf is open. In addition, the spring device forms an energy accumulator that reduces the effort required to lift the wing.

A lift-and-slide element according to the invention can comprise a lever which is mounted on the sash or on a component fixedly connected to the sash so that it can pivot about a lever axis running transversely to a longitudinal axis of the running rail and has two lever arms which each carry at least one roller of the roller arrangement . When the front roller with respect to the closing direction of the wing enters the recess, the relevant lever arm pivots downwards. This can be done by swinging the other lever arm up accompanied, with a total of the wing lowers compared to the career. The lever is preferably designed in such a way that after the front roller has been moved into the recess, the rear roller remains on the base plane of the track. When the front roller is extended from the recess, the rear roller forms a support, the pivot axis of the lever forms the point of application for the weight of the wing and the front roller forms the point of application for the lifting force. The point of application for the lifting force is therefore further away from the support than the point of application for the weight force, so that the force required to lift the wing is reduced by the lever.

According to one embodiment of the invention, the effective lever lengths of the two lever arms are the same, resulting in a simple and space-saving construction. Only half the weight force has to be used to lift the wing.

Alternatively, it can be provided that the effective lever lengths of the two lever arms are in a ratio of at least two to one, preferably at least three to one, to one another. This further reduces the effort required to lift the sash, so that, for example, a sash weighing several hundred kilograms can be lifted by manual displacement.

The lever can be mounted on the carriage frame of a carriage, the carriage frame being attached to the wing. In particular, a lever axis running transversely to the displacement direction of the wing can be mounted on two opposite support sections of the carriage frame for mounting the lever.

One of the lever arms can be led out of the carriage frame in order to allow the lever arm to be of any length, in principle, for a given frame size.

Furthermore, a carriage with a carriage frame and at least two rollers can be mounted on one of the lever arms. This enables improved support, especially with heavy wings.

Further developments of the invention are also specified in the dependent claims, the description and the attached drawings.

are lateral cut-away partial representations of a lift and slide door, which has a wing Show lift and slide door in different successive phases of assembly.

1 and 2 show in simplified form the lower area of a lift and slide door, which includes a frame 13 and a wing, not shown here. The wing is by means of two carriages 15, one of which in the 1 and 2 only one is shown, in a horizontal displacement direction V relative to the frame 13 displaceable. The in the 1 and 2 left-pointing displacement direction V corresponds to the closing direction of the wing. Accordingly, the illustrated carriage 15 may be referred to as "front carriage". If necessary, more than two carriages 15 can be provided to move the wing.

Each of the carriages 15 has a carriage frame 17 which is fastened to the underside of the wing in a basically known manner. Rollers 19a, 19b mounted on the carriage frame 17 each roll on a running rail 21 arranged below the wing. According to the closing direction of the sash, the roller 19a on the left in the picture is referred to below as the "front roller", while the roller 19b on the right in the picture is referred to as the "rear roller".

In the exemplary embodiment shown, the running rail 21 forms part of the window frame 13. However, it could also be designed as a separate component, for example as a ground sill. The upper side of the running rail 21 forms a running track 25 along which the wing can be displaced by means of the running carriage 15 .

Like in particular 2 shows that the rollers 19a, 19b are not mounted directly on the carriage frame 17, but rather on a lever 27, which in turn is mounted on the carriage frame 17 such that it can pivot about a horizontal lever axis 29.

As shown, the lever 27 has two lever arms 30a, 30b each carrying a roller 19a, 19b. The axes of rotation 33 of the rollers 19a, 19b are located at the ends of the lever 27, although this is not mandatory.

The track 25 defines a base plane 37, which runs horizontally when the lift and slide door is installed and is provided for the horizontal movement of the wing by means of the two carriages 15. There are indentations 39 at two points on the track 25, but in 1 and 2 only the front of the two depressions 39 can be seen. This means that the track 25 is lowered in relation to the base plane 37 at these points when the lift-and-slide door is installed. The two indentations 39 are spaced apart from one another along the longitudinal axis 40 of the running rail 21 by an amount which corresponds to the spacing of the running carriages 15 . Otherwise, the two indentations 39 are designed identically with regard to the features that are essential to the invention, so that only the front indentation 39 shown is described below.

The recess 39 is provided with a cover flap 45, which lies between an in 1 horizontal position shown and one in 2 shown inclined position is pivotable. The cover flap 45 covers the recess 39 in the horizontal position. In 1 a gap is shown between the free end 47 of the cover flap 45 and the adjoining section of the raceway 25 in order to increase the visibility of the cover flap 45. However, it is preferred that the border of the cover flap 45 in the horizontal position adjoins the adjoining sections of the raceway 25 without a gap, so that the raceway 25 defines a continuous surface. A spring device 48 such. B. a compression spring ensures that the cover flap 45 is biased into the horizontal position.

In the inclined position, the cover flap 45 forms a ramp 49, which retracts the front roller 19a of the carriage 15 into the recess 39 and also allows the front roller 19a to be extended out of the recess 39 . When the front roller 19a enters the recess 39, the wing lowers automatically, as will be described in more detail below.

If the wing and with it the front carriage 15, starting from the in 1 shown position is shifted in the displacement direction V, the front roller 19a of the carriage 15 reaches the cover flap 45. Due to the weight of the wing resting on the roller 19a, the cover flap 45 is moved into the inclined position according to the force of the spring device 48 2 pivoted, with the front roller 19a drops accordingly. Since the rear roller 19b is still on the base plane 37, ie in a higher position than the front roller 19a, the lever 27 is inclined as shown. The carriage frame 17 remains in its horizontal orientation. However, as a result of the front roller 19a moving into the recess 39, the distance between the underside 55 of the carriage frame 17 and the base plane 37 has been reduced, as shown in FIG 1 and 2 is shown by the amounts D1 and D2. Since the front rollers 19a of both carriages 15 enter the respective depressions 39 at the same time, the retraction process results in a tilt-free lowering of the sash overall.

In the 2 shown lowered position of the carriage frame 17 is preferably connected to a fixing position of the wing. For example, the carriage frame 17 could be attached to the wing such that the underside of the wing rests on the track 25 when the carriage frame 17 is in the lowered position. Furthermore, it is preferred that there is an air gap between the underside of the wing and the track 25 when the carriage frame 17 is in the raised position according to FIG 1 located. The wing can then be moved essentially freely on the runway 25 . The front rollers 19a preferably reach the retracted position in the depressions 39 just when the wing has reached its closed position.

If the wing and with it the front carriage 15, starting from the in 2 shown position is displaced counter to the direction of displacement V, the front roller 19a rolls up the ramp 49 and thereby lifts the carriage frame 17 while pivoting the lever 27 until it is again in the 1 has reached the position shown. The spring device 48 causes the cover flap 45 to close again. Furthermore, the spring device 48 can support the lifting. The lever 27 causes the lifting force to be exerted on the front roller 19a to be reduced in relation to the weight of the wing. Overall, the simultaneous extension of the front rollers 19a of both carriages 15 from the respective depressions 39 results in the wing being lifted without tilting.

Because of the depressions 39, a displacement movement of the wing when the lift-and-slide door is closed is partially converted into a lowering movement of the wing. As a result, when the lift-and-slide door is closed, the sash can be automatically lowered without operating a handle or the like. Likewise, due to the depressions 39, a displacement movement of the wing when the lift-and-slide door is opened is partly converted into a lifting movement of the wing. This enables the sash to be raised automatically when the lift-and-slide door is opened.

While at the in 1 and 2 shown embodiment, the effective lever lengths of the two lever arms 30a, 30b are the same, show 3 and 4 an alternative embodiment with a modified lever 27', in which the effective lever lengths h1, h2 of the two lever arms 30'a, 30'b are in a ratio of four to one to one another. Lever 27' is like that previously referred to in FIG 1 and 2 Lever 27 described is mounted on the carriage frame 17 of the carriage 15 so as to be pivotable about a horizontal lever axis 29 . The lever axis 29 is therefore stationary with respect to the carriage frame 17 .

At the end of the shorter lever arm 30'b there is a bearing axle 95, by means of which an additional carriage 57 arranged inside the carriage frame 17 of the carriage 15 is mounted on the lever 27'. The additional carriage 57 comprises a carriage frame in the form of a base body 56 and two support rollers 58 mounted on the base body 56. The longer lever arm 30'a is arcuate and led out of the carriage frame 17 of the carriage 15. At the end of the bent lever arm 30'a is mounted a control roller 59 which, as shown, has a smaller diameter than the support rollers 58.

How out 4 shows, the running rail 21 'in the non-inventive embodiment according to 3 and 4 a depression 39' which is not covered by a flap. In principle, however, the depression 39' can also be covered by a flap as described above in an embodiment according to the invention. The base plane 37 transitions here via fixed ramp sections 60 of the track 25' into the recess 39'. The central area 61 of the depression 39' also has a cross-sectional shape which is adapted to the outer diameter of the control roller 59 mounted on the longer lever arm 30'a. The control roller 59 can be moved into and out of the recess 39' via the ramp sections 60, which are curved here.

The raising and lowering of the wing works in the embodiment according to FIG 3 and 4 as above with reference to 1 and 2 described. When the control roller 59 is extended out of the recess 39', the bearing axis 95 forms a support, the lever axis 29 forms the point of application for the weight of the wing and the control roller 59 forms the point of application for the lifting force. Since the distance between the control roller 59 and the bearing axis 95 is five times the distance between the lever axis 29 and the bearing axis 95, the force to be applied for lifting is only one-fifth of the weight.

The ratio of the lever lengths h1, h2 to one another is decisive for the distribution of the weight force acting on the carriage frame 17 to the control roller 59 on the one hand and the support rollers 58 on the other hand. In the embodiment according to 3 and 4 the proportion 91 of the weight force to be supported by the control roller 59 is only a quarter of the weight force 92 to be supported by the support rollers 58 and only one fifth of the total weight force 93 to be supported.

The Figures 5-7 show the upper part of the in Figures 1-2 shown lift-and-slide door. The attached to a ceiling 77 upper profile 69 of the frame 13 runs parallel to a lower rail - such. B. the rail 21 according to 1 and 2 or according to the running rail 21' 3 and 4 - And is designed to guide the upper edge 71 of the wing 75. For this purpose, the upper profile 69 has a seat 79 in which a guide rail 70 is received in a slidingly pivoting manner. The corresponding pivot axis 72 runs parallel to the displacement direction V ( 1 ). A longitudinal groove 76 is formed in the guide rail 70, into which an upper rib 80 of the wing 75 can be inserted or pushed.

Furthermore, a retaining edge 85 is formed on the upper profile 69, to which a sealing element 87 is attached. The retaining edge 85 is used to grip behind a side projection 86 of the wing profile.

To insert the sash 75 into the window frame 13, the sash 75 is first positioned as in figure 5 shown in the tilted position on the frame 13 and the upper rib 80 is inserted into the longitudinal groove 76. Due to the tilted position of the wing 75, the side projection 86 can be guided past the retaining edge 85. Then the wing 75 as in 6 shown tilted into the vertical position, the holding edge 85 engaging behind the side projection 86 . In a final step, the wing 75 is lowered, with the side projection 86 as in 7 recognizable comes into contact with the sealing element 87. The wing 75 can now be moved in the manner described above. Removing the wing 75 from the window frame 13, for example as part of a necessary repair, can be easily carried out by lifting the wing 75, tilting the wing 75 and then pulling the upper rib 80 out of the longitudinal groove 76.
