Description

The present invention relates to a fitting arrangement for a lift-slide element such as a lift-slide door or a lift-slide window, which has a fixed frame and a sash which can be moved in a raised position along a lower track in a direction of displacement relative to the frame includes. The invention further relates to a lifting and sliding element with such a fitting arrangement.

Fitting arrangements of the type mentioned at the beginning are known, for example, from the area of patio, balcony or winter garden doors. The fixed frame usually has a permanently attached running rail in the floor area. A pivotable handle lever is usually provided on the wing, by means of which the wing can be raised relative to a carriage arranged on the underside of the wing. In a raised state of the wing created in this way, it is possible to move the wing along the running rail with little friction.

Known fitting arrangements require a relatively large amount of space on the sash side and thereby cause the sash edge, i.e. the generally non-transparent area of the sash, to be relatively wide.

The document FR 2 244 366 A5 describes a fitting arrangement according to the preamble of claim 1. The documents DE 18 08 276 A1 and DE 15 59 725 B1 describe further state of the art.

The invention is based on the object of providing a fitting arrangement for a lift-slide element, which makes it possible to make the edge of the sash as narrow as possible and thus enlarge the transparent area of the sash and at the same time provide the required installation space for movement of the rail strip in a displacement direction to minimize.

The task is solved by a fitting arrangement according to claim 1. Since the parts causing the adjustment are arranged on the frame side, no adjustable element, i.e. no adjustable carriage, no longer needs to be provided on the sash. An adjustment mechanism required to adjust the adjustment element can also be installed in the frame, so that an adjustment mechanism is no longer required on the sash. The wing edge can therefore be made relatively narrow and the transparent wing surface can be enlarged relative to the wing edge surface.

The rail bar is adjustable in a rectilinear movement perpendicular to the direction of displacement between the lowered position and the raised position. In other words, the rail bar moves between the lowered position and the raised position along a straight line that is perpendicular to the direction of displacement. Since this does not result in any movement of the rail strip along the direction of displacement, no installation space needs to be provided for such a movement.

Advantageous embodiments of the invention can be found in the subclaims, the description and the drawings.

According to an advantageous embodiment, the deflection element comprises at least one lever. However, the deflection element can take any form of part or system that is designed to allow movement of the adjusting element to divert the rail bar into a transverse movement.

For example, a wedge can be formed on the adjusting element, on the sloping surface of which the rail bar rests and by moving the adjusting element, the rail bar can be slidably moved along the sloping surface from the lowered position to the raised position.

The lever can be rotatably coupled to the adjusting element and/or the rail bar. By coupling the lever with the adjusting element and the rail bar in this way, the rail bar can be easily moved from the lowered position to the raised position and back.

Alternatively, the lever can, for example, also be rotatably attached to the frame and only rest on the rail bar.

According to a preferred embodiment, the deflection element comprises a second lever which is effective between the frame and the adjusting element. For example, one end of the second lever can be rotatably attached to the adjusting element and the other end can be rotatably attached to the rail bar.

In order to be able to form a symmetrical lever arrangement, the first lever and the second lever are preferably of the same length.

In particular, the first lever can be rotatably mounted at a first coupling point with the adjusting element and at a second coupling point with the rail strip, and the second lever can be rotatably mounted at a third coupling point with the frame and at a fourth coupling point with the adjusting element.

In order to distribute the load of the wing over several levers, several first levers, in particular exactly two first levers, can be rotatable at the first coupling point with the adjusting element and at the second coupling point with the rail bar be mounted and / or several second levers, in particular two second levers, can be rotatably mounted at the third coupling point with the frame and at the fourth coupling point with the adjusting element. The plurality of first levers and/or the plurality of second levers of a deflection element can each be arranged on opposite sides of the adjusting element.

According to one embodiment, the first lever and the second lever together form an expanding lever lifting unit. This enables particularly good power transmission.

According to a special embodiment, the first coupling point and the fourth coupling point lie on an axis of rotation. This means that the formation of a coupling point on the adjusting element can be saved.

In order to ensure that the rail strip remains in the raised position through self-locking in the raised position of the rail strip and consequently the lifting position of the adjusting element, the at least one lever can be in the lifting position of the adjusting element perpendicular to the rail strip and/or the adjusting element, i.e. in mounted position State perpendicular to the floor surface. With two levers, it is advantageous if both levers are arranged perpendicular to the rail bar and/or the adjusting element in the raised position of the rail bar.

Since the wings to be lifted often have considerable weight, it is advantageous if the adjusting element extends along the rail strip in the direction of displacement and a plurality of deflection elements are formed or arranged along the adjusting element. In this way, the adjustment movement can be redirected via several deflection elements, whereby the individual deflection element is subjected to less stress. These are the deflection elements Lever, which together form an expansion lever lifting unit, the several deflection elements form a statically determined guide for the rail bar.

In order to minimize the friction when opening and closing the sash to a rolling friction, an exclusively rotatably mounted roller can be provided on the sash side, which is in contact with the raceway in an installed position - at least in the raised position of the rail strip. Preferably, the roller is rotatably mounted on an axle which is aligned perpendicular to the direction of displacement. The diameter of the roll should preferably be as large as possible in order to ensure smooth rolling. However, the diameter should only be as large as necessary, as this limits the minimum width of the sash frame.

The roller and the running rail preferably have corresponding running surfaces, by means of which the wing can be moved in a guided manner. For example, the roller has a particularly V-shaped groove on its peripheral surface and the running rail has a matching, particularly V-shaped elevation. The survey can then serve as a career path for the role.

The object is also achieved by a lift-slide element, which is designed, for example, as a lift-slide door or lift-slide window and includes a fitting arrangement according to the invention.

The invention is described below using a purely exemplary embodiment with reference to the accompanying drawings. Show it:

a side view of the frame-side components of the fitting arrangement Fig. 1 .

The figures show a fitting arrangement 10 of a lift-slide door 12 with a frame 14, a sliding door leaf 16 ( Fig. 1 ) and a fixed door leaf 18.

As in Fig. 1 shown, the movable door leaf 16 and the fixed door leaf 18 each have a transparent triple-glazed visible surface 20, 22 and a leaf edge 24, 26 made, for example, of plastic. The wing edge 24, 26 is designed to be as narrow as possible in order to enable a large, transparent viewing surface 20, 22. A width B of the wing edge 24 is limited primarily by a diameter of a roller 28 accommodated in the wing edge 24 of the displaceable door wing 16.

The roller 28 is completely arranged in a recess 30 and is rotatably mounted there about an axis of rotation 32. The roller 28 has a V-shaped groove 34 on its peripheral surface, into which a rail-like V-shaped elevation 36 of a rail strip 38 arranged on the frame side engages. In this way, several rollers 28 are brought into engagement with the V-shaped elevation 36 of the rail strip 38 along an underside 39 of the displaceable door leaf 16. The V-shaped elevation 36 protrudes from the profile of the frame 14 in that the V-shaped elevation 36 protrudes through an elongated slot-shaped recess 37 on the top of the frame 14.

In order to raise the displaceable door leaf 16 from a lowered position in which the door leaf 16 cannot be displaced to a raised position in which the door leaf 16 is displaceable, the rail strip 38 is between a lowered position (see Fig. 1 and 2 ) and adjustable to a raised position. To adjust the rail strip 38, an adjusting element 40 is provided, which can be controlled, for example, by means of an electric motor. The adjusting element 40 is designed in the form of a strip which extends along the rail strip 38 in the displacement direction 41.

The adjusting element 40 is rotatably coupled to a plurality of first levers 44 at first coupling points 42. The first levers 44 are in turn rotatably coupled to the rail strip 38 at second coupling points 46. Furthermore, the adjusting element 40 is rotatably coupled to second levers 50 at fourth coupling points 48, which correspond to the first coupling points 42. The second levers 50 are in turn rotatably coupled to the frame 14 at third coupling points 52. The first levers 44 and the second levers 50 are of the same length and the second coupling points 46 and the third coupling points 52 are as shown in Fig. 2 can be seen, in pairs on top of each other.

By adjusting the adjusting element 40 (in Fig. 2 to the left), the first levers 44 and the second levers 50 are spread and the rail bar 38 is thereby raised relative to the frame 14. When the rail strip 38 is lifted, it pushes the displaceable door leaf 16 upwards, so that the underside 39 of the displaceable door leaf 16 no longer rests on the frame 14, but only the roller 28 rests on the rail strip 38. In a raised position of the rail strip 38 (not shown), the displaceable door leaf 16 can thus be moved in the direction of the displacement direction 41 without significant friction losses, that is to say only under rolling friction. In this raised position, the first levers 44 and the second levers 50 are aligned parallel to one another and extend in the direction of gravity, that is to say perpendicular to the rail bar 38. As a result, no force is required to hold the adjusting element 40 in the lifting position, not shown, since this System is metastable and therefore self-locking.

As in Fig. 1 can be seen, two first levers 44 and two second levers 50 are provided per deflection element 54, that is, in the embodiment shown here, per first coupling point 42. The first levers 44 are always aligned parallel to one another and move synchronously with one another. The same applies to the second levers 50. The first levers 44 are arranged on diametrically opposite sides of the adjusting element 40 and are rotatably coupled to it. The first levers 44 are also rotatably coupled to both sides on the rail strip 38 by means of a first axis 56. Two second levers 50 are also provided per deflection element 54, which are each rotatably coupled to the frame 14 on both sides by means of a second axis 58. At the first coupling point 42, the rail bar 38 is rotatably mounted together with the two first levers 44, the two second levers 50 and the adjusting element 40 on a third axis 60. There are two arms of the rail bar 38 on the outside of the third axis 60, towards the middle first the two second levers 50, then the first two levers 44 and the adjusting element 40 in the middle.

By returning the adjusting element 40 from the raising position to the lowering position ( Fig. 1 and 2 ) the first levers 44 and the second levers 50 are brought back into an obtuse angle to one another until the rail strip 38 and/or the adjusting element 40 rest on a support surface of the frame 14.

On the underside 39 of the movable door leaf 16 and the fixed door leaf 18 there are two seals 62, 64 ( Fig. 1 ) arranged, which extend in the displacement direction 41. In the event that, for example, the seals 62, 64 are disabled due to an open door leaf 16 and water should penetrate through the recess 37 into the frame 14 when it rains, a drain 66 is provided, which directs the water into a drainage channel 68 .

To ensure barrier-free access through the door, the frame 14 is installed flush with a floor 70 on the inside and outside.

By means of the expansion lever lifting unit formed by the first and second levers 44, 50, large, heavy door leaves 16 can be lifted with relatively low forces.
