Description

The invention relates to a drive for holding separating elements and a separator provided with such a drive.

Glass or wood walls, doors or shops are often used for separating or designing rooms or closing furniture.

Since a rotatably held separating element after opening a piece of furniture usually disturbing appears in appearance, solutions have been developed that allow the separating element after opening the piece of furniture in a space provided therein, optionally limited by an intermediate wall space to insert.

From [1], US 5'149'180 A, a piece of furniture with a displacement device is known, by means of which a rotatably held on a stop profile door from a use position is retractable into a door compartment, which has at least one side wall. The stop profile is held by a scissors cross, which has two mutually hinged scissor elements when entering the door compartment and when extending in a vertical position. One of the two scissors elements is rotatably supported by the upper end at the top of the stop profile on a scissor bearing and rotatably supported by the lower end within the door compartment in a guide device and vertically. The second scissor element is rotatable with the upper end within the door compartment in an anchorage and held rotatably and vertically displaceable with the lower end on the underside of the stop profile. When sinking and extending the door, therefore, the upper ends of the scissors elements always remain at the same height, while the lower ends are moved vertically. The pivot points Ideally, the ends of the scissor elements always form a rectangle. By releasing the scissor bearing from the stop profile, this can be moved vertically to position the door within the door compartment equidistant from the top and bottom of the cabinet.

Furthermore, in [1] an upper and a lower rail are provided, along which the stop profile is guided by means of guide plates to prevent twisting and jamming of the scissors cross.

However, especially with heavy separating elements, the use of guide straps is no longer satisfactory. In this case, a drive with wheels, which are guided on a running rail, is preferably mounted on the upper end of the stop profile. The weight of the separator is therefore carried by the drive, while the remaining torque is absorbed by the significantly relieved scissors cross.

The essential factor here is again the correct adjustment of the height of the stop profile held by the drive. The optimal function of the displacement device is namely guaranteed only if all elements are properly matched. It is therefore again of central importance that the height of the stop profile can be precisely adjusted relative to the running perpendicular to the running rail with simple measures. It should be avoided that the drive for the adjustment of the stop profile must be solved and moved, which would make a simple and precise adjustment practically impossible.

Even with other devices with separating elements, such as sliding doors, it is often necessary to adjust the height of the separating elements. If a sliding door is held with two guided in a rail drives, so it is also required that the sliding door through the Height adjustment for each drive is aligned horizontally.

From [2], US6418588B1 , It is known to adjust the height of a separating element by stepwise turning a connecting screw, the threaded shaft is screwed into a threaded bore in the body of the drive and the screw head is mounted in a fitting, which is provided at the upper edge of the separating element. However, this device requires a lot of space below the drive for accessing a tool by means of which the connecting screw is detected and rotated. The separator can therefore not be pulled arbitrarily close to the drive.

From [3], EP1460225A1 , a drive for a sliding door is known, which comprises a support body which is inserted into a suitable recess in the upper edge of the sliding door. A support bolt rotatably mounted in the supporting bolt, at its lower end a bevel gear is formed, can be rotated by a screwdriver, which is inserted into a recess in the support body, and so the sliding door with respect to the suspension are moved vertically. Even with this solution, enough space for the support body is provided below the drive. Furthermore, the top of the sliding doors to edit accordingly and provided with a recess, which is associated with the corresponding effort and hardly possible with different sliding doors, especially glass doors.

From document FR2903446A1 a sliding door drive is known, which has an inner housing provided with an impeller having inclined roof surfaces, along which wedge elements slidably to move the inner housing with impeller to the outside and adjust the height of the crashed onto the drive partition member accordingly. For hanging the separator on a track this drive is not provided.

From the documents FR2441042A3 . DE3338146A1 , and JP9021268A drives are known in which an actuating element is held in a guide profile and laterally displaceable.

From document WO9738198A1 a device is known in which two cylinders are displaceable by means of screws in opposite directions to each other along a mechanism support to adjust the height of a held by the device separating element.

Out DE2847578A1 is a guide device for linearly arranged on a carrier arranged objects known. This guide device allows in particular the parallel adjustment of furniture bays.

The present invention is therefore an object of the invention to provide an improved drive for suspending a sliding along a running rail and optionally rotatable separating element, which is adjustable in a simple manner, so that a vertical displacement of the separating element is easily and precisely adjustable.

In particular, a drive is to create, which is compact and takes up little space, so that the sliding door can be raised as far as possible against the running rail.

Furthermore, a slidable along a running rail and optionally rotatable separating element is provided, which is connected to such a drive.

This object is achieved with a drive and with a separator provided with this drive, which have the features specified in claim 1 or 9 features.

Advantageous embodiments of the invention are specified in further claims.

The drive, which serves to hold a displaceable separating element, has a drive body and at least one impeller, which rolls along a running rail during displacement of the separating element.

According to the invention, the drive body has a housing, in the interior of which an adjusting element, which projects outwardly through a housing opening and is displaceable at least approximately perpendicularly to the running direction of the drive, is displaceably mounted. The adjusting element is provided within the housing with a holding element which cooperates with an adjusting element which is displaceable relative to the holding element by means of a screw held by the drive body relative to the holding element, so that the adjusting element is held in a selected position. In this case, either the outwardly projecting from the housing part of the actuating element with the at least one impeller and the drive body is connected to the separating element. Alternatively, the outwardly projecting from the housing part of the actuating element with the separating element and the drive body is connected to the at least one impeller. By integrating an adjusting device into the body of the drive or into a housing provided therein, an extraordinarily more compact design of the drive succeeds. This drive allows dividers, such as glass or wood sliding doors, to be raised or even pulled close to the track. Disturbing gaps below the track, through which wind and sound pass through, can be avoided. On screens that cover these columns can normally be omitted. At least, small size panels can be used. Furthermore, the drive according to the invention can be adjusted in a simple manner. It is particularly advantageous that the required tool can be supplied laterally, so below the drive no space for manipulations of the installer must be kept free. According to the invention, the drive is adjusted from both sides, so that the installer can choose the appropriate page.

It is also important that the adjusting device is optimally protected within the drive against external influences, so that the drive after a long period of operation still works properly, even if it is installed in critical places that are exposed to the weather.

In a preferred embodiment, a support lever is rotatably supported on the outwardly projecting part of the actuating element, held on the on either side of each of the wheels by means of axles. By using a rotatable support lever results in optimal load distribution on both wheels. Regardless of the inclination of the recording profile relative to the track rail, the drive therefore always optimally performs its service. A one-sided load only one impeller, which could lead to early wear is avoided.

If the wheels, however, are provided on one side or on both sides of the drive body, so the actuator can be advantageously adapted to the fitting of the sliding door. For example, it is possible to provide an opening in the glass plate or wooden plate of the sliding door, in which the actuator is mounted. The actuating element has a holding rod, on the upper side of the support lever rotatably held by a central axis and on the underside of a retaining wedge is provided. The upper wedge surface of the retaining wedge, which is inclined relative to the running direction of the drive, cooperates with the lower wedge surface of a Justierkeils which is displaceable by means of a drive body held by the adjusting screw relative to the retaining wedge. With the displacement of the Justierkeils the retaining wedge will therefore be moved up or down. Typically, the setscrew in the drive cage is parallel to the drive direction.

According to the invention provided with a threaded shaft adjusting screw is used, which has at each end a screw head, which are each rotatably held in a bearing opening of the drive housing, but not displaceable. The bearing openings are provided in two opposite sides of the drive housing, which is why the set screw passes completely through the drive housing. The threaded shaft of the adjusting screw is held in a threaded channel of the Justierkeils, so this is moved with each rotation of the adjusting screw along this. The set screw can thus be accessed from both sides of the drive housing. An adjustment is thus possible from both sides.

The inventive drive can therefore be used advantageously in the displacement device described below and for the assembly of any separating elements. The invention will be explained in more detail with reference to drawings. Showing:

the drive 4 of FIG. 2 in a particularly preferred embodiment, in which the adjusting element 45 is connected to the fitting 111 of the sliding door 11 and the body 41 of the drive 4 is provided on one side or on both sides with wheel axles 441, of which wheels 44 are held.

FIG. 1 shows a displacement device 2 for a piece of furniture 1, which has a stop profile 21, are provided on the hinges 3, which serve to hold a separating element 11 (see FIG. 4 ). The stop profile 21 is typically held by a scissors cross in a vertical position, as described in [1]. The displacement device 2 makes it possible to move the separating element 11 into a door compartment 14, which is delimited by an outer side wall and an intermediate wall 13 of the piece of furniture 1.

The stop profile 21 is held by a drive 4 according to the invention and guided along an upper running rail 27. As a result, the load of the separating element 11 is received by the drive 4 and the optionally provided scissors cross relieved.

The inventive drive 4, which has a drive body 41 with a housing 411 in which an adjusting device is arranged, will be described below with reference to the FIGS. 1 . 2 and 3 explained in more detail.

FIG. 2 shows the drive 4 from FIG. 1 with open housing 411, in which the adjusting elements 45, or 451, 452 and 46 and 47 are provided.

FIG. 3 shows the drive 4 from FIG. 2 in an exploded view.

The drive 4 has a drive body 41 with a drive housing 411, in which an adjusting element 45 is mounted vertically displaceable, which consists of a vertically oriented holding bar 451 and a retaining wedge 452 attached to the underside thereof. On the upper side of the support rod 451, a bearing hole 451 is provided, into which a center shaft 431 is insertable, which rotatably supports a support lever 43 in the middle. The support lever 43 has on both sides depending on a receiving opening 432, in which the axes 441 are held by wheels 44. The support lever 43 therefore serves as a rocker, which follows the inclination of the track 27 and the load evenly distributed to both wheels 44.

The holding bar 451 is held vertically displaceably in the housing 411 of the drive body 41 between two guide bars 4114 and projects outwardly through a housing opening 4111. Between the two guide bars 4114, the holding rod 453 is held by means of a bearing block 421 which is arranged on the cover 42 of the drive housing 411. On the housing cover 42 receiving openings 422 are provided for end screws 423, which are screwed into threaded holes 4113 in the drive body 41. After attachment of the support rod 451 is therefore held vertically displaceable.

Further, in the drive housing 411, a set screw 46 is provided which has at both ends a screw head 461 and therebetween a screw shaft 462 with a thread. The two screw heads 461 are rotatably supported in bearing holes 4112 provided in opposite sides of the drive case 411. The bearing openings 4112 are at the same height, which is why the adjusting screw 46 is aligned horizontally and at the same time perpendicular to the direction of displacement of the retaining rod 451.

The screw shank 462 of the adjusting screw 46 is screwed into a threaded channel 471 which completely passes through an adjusting wedge 47. The Justierkeil 47 lies above the retaining wedge 452, wherein two inclined to the horizontal wedge surfaces abut each other, as soon as the retaining rod 451 is pulled upwards. By the rotation of the adjusting screw 46, the adjusting wedge 47 moves in the horizontal direction from one side of the drive housing 411 to the other side, whereby the retaining wedge 452 is displaced downwards or under load.

In this way, the height of the drive body 41 and the associated with the mounting part 412 stop profile 21 can be precisely adjusted. The adjusting screw 46 can be operated from two sides of the housing 411 and thus also from the front side of the piece of furniture 1. The height is adjusted so that the weight of the separating element 11 is preferably completely taken over by the drives 4 and the separating element 11 is held at the same time in the intended height.

FIG. 4 shows the drive 4 and the stop profile 21 of FIG. 1 with the assembled partition member 11. The mounting member 412 connected to the drive body 41 is inserted into a mounting channel 2111 provided in the abutment profile 21. The partition 11, ie the door of the piece of furniture, is oriented forwards, so that it can either be moved into the door compartment or turned to close the piece of furniture.

The inventive drive 4 with the described height adjustment can be used advantageously in other devices. It is not absolutely necessary that the holding rod 451 is connected via a rotatable support lever 43 with the wheels. The support lever 43 may also be fixedly connected to the support rod 451.

Further, the wheels 44 or rollers, which may be provided in any number, also be connected directly to the drive body 41, while the support rod 451 is connected to a partition member 11, such as a sliding door and can hold them in selectively adjustable height.

The holding bar 451 can be configured as desired. For example, the support rod 451 may be formed as a slender hook, by means of which the fitting 111 of a separating element 11, for example a wooden plate or a glass plate is detected. Screw connections between the drive and the fitting of the separating element, as shown for example in [4], US 6,052,867 can therefore be drastically simplified. The fitting connected to the separating element can be reduced in its dimensions to the minimum and no longer requires the storage of movable parts, such as screws.

Nevertheless, it is of course also possible to form the retaining bar as a screw, which is preferably rotatably connected to the retaining wedge. In this case, based on the rotation of the holding rod or the retaining screw a coarse adjustment and based on the adjusting a fine adjustment can be performed. In this case, a locking element, for example a locking screw is preferably provided in the drive body, by means of which the helical holding rod can be fixed. For example, a vertically extending groove is provided in the holding rod, in which the locking screw can be screwed to hold these rotationally fixed and only vertically displaceable.

The inventive drive 4 can therefore be connected in various ways with any separating elements 11. The separating elements can be made of any materials, such as glass, metal, wood or plastic.

FIG. 5 shows the drive 4 from FIG. 2 with a mounting part 412, which is connected to a fitting 111 of a sliding door 11.

FIG. 6 shows the drive 4 from FIG. 1 In a particularly preferred embodiment, in which the adjusting element 45 is connected by means of a connecting element 455 with the fitting 111 of the sliding door 11. The connecting element 455 has the shape of a screw head, which can be hooked into the fitting 111. The body 41 of the drive 4 is provided on one side or on both sides with wheel axles 441, which are each provided with an impeller 44. Advantageously, the drive 4 including the integrated in the housing 411 adjusting device is completely received in the track rail 27.

In FIG. 6a It is shown that any rails 27 can be used for the drives 4 according to the invention. For drives 4, which are only provided on one side with wheels 44, normally L-shaped rails 27 are used. For drives 4, which are provided on both sides with wheels 44, normally U-shaped rails 27 are used. The wheels 44 are guided on foot elements 271.

As the FIGS. 4 . 5 and 6 show, the inventive drive 4 can be used in many ways. It is therefore pointed out that various further configurations of the drive 4 can result from reversing the mode of operation, in particular kinematic reversal.
