Roller carriage for the reception of a sliding door with a height adjusting device

Abstract

A roller carriage for the reception of a sliding door includes a roller module for the displaceable affixing at a roller running path and a basic body for the attachment to the sliding door. The basic body is supported at the roller module to be displaceable along a direction of gravity (SKR) for a fine-tuning movement, wherein a first adjusting component for an adjusting movement is supported at the basic body to be movable. For a movement of the basic body along a direction of gravity in relation to the roller module when performing the adjusting movement, the first adjusting component is in operative connection with a second adjusting component of the roller module.

DETAILED DESCRIPTION OF THE DRAWINGS

(10) An embodiment of a roller carriage 10 is illustrated in an isometric illustration in FIG. 1. Basically, said carriage includes two structural components. In this case, the components are on the one hand, the roller module 20 and, on the other hand, the basic body 30. In this case, both structural components, namely the roller module 20 and the basic body 30 include a plurality of individual parts. Said individual parts will be briefly explained in the following.

(11) Here, the roller module 20 is equipped with a bearing device 26. Said bearing device 26 is equipped in this case with two rollers 26a, which are supported to be rotatable at a basic body of the roller module 20. Said rollers 26a can be placed onto, respectively inserted into a roller running path 120, as can be clearly seen in FIG. 2 and FIG. 3. A part of a height adjustment device 70 is provided furthermore at the roller module 20. The detailed components of said height adjustment device 70 are in particular illustrated in the FIGS. 4 and 5. Thus, a first adjusting means 32 is provided, which by means of a manipulation interface 36 is able to perform an adjusting movement. As, in this case, the first adjusting means 32 is configured as a threaded bolt in an adjusting thread 32a, a rotary motion is performed at the manipulation interface 36, which motion simultaneously produces a linear translatory motion of the first adjusting means 32. Via a corresponding contacting portion 34, the first adjusting means 32 is in operative connection with a counter-contacting portion 24 of the second adjusting means 22. In this case, the explicit action of said adjusting device relates to transforming the adjusting movement into a fine-tuning movement along the direction of gravity SKR.

(12) As can be seen in FIG. 1, the roller carriage 10 is equipped with a plurality of different mounting devices 90, which are able to provide different mounting functions. In this case, the already described fine-tuning function of the height of the sliding door 110 is provided by means of the mounting device 90 in the shape of the height adjusting device 70. Furthermore, a mounting device 90 in the shape of a securing device 50 is provided, which, after completed fine-tuning of the height of the sliding door 110, provides a clamping fixing between the basic body 30 and the roller module 20.

(13) In this case, a further mounting device 90 is disposed in an accessory device 40, which is provided by means of a corresponding interface and an affixed accessory module 300. Moreover, a lift-off protection device 60 is provided as a mounting device 90, which provides a lift-off protection against unwanted removal of the roller carriage 10 out of the position in which it is inserted into the roller running path 120. Furthermore, an attachment device 80 is provided as a glass clamp for a mounting device 90, in order to affix the sliding door 110 in a clamping manner.

(14) All mounting devices have in common that they include at least one mounting means 92, in order to be able to perform a corresponding mounting movement. Moreover, a manipulation interface is provided, intended to allow for performing exactly said mounting movement with the mounting means.

(15) As moreover revealed in FIG. 1, the roller carriage 10 has different sides, namely the first side 12 and the second side 14. In this case with regard to their manipulation interface 96, all mounting devices are preferably aligned from the same side, namely the first side 12 opposite to the second side 14, on which the bearing device 26 is disposed. This arrangement offers a considerably simpler access.

(16) FIG. 2 reveals how a sliding door 110 is retained by means of two roller carriages 10 according to FIG. 1, and that the two roller carriages 10 are already inserted into the roller running path 120. In a lateral illustration according to FIG. 3, in particular the correlation of the rollers 26a with the roller running path 120 is well visible.

(17) FIGS. 6-8 illustrate details with regard to different embodiments of the height adjusting device 40. Said FIG. 6 shows a solution, in which the first adjusting means 32 performs a combination of rotary motion and linear motion. The first adjusting means 32, configured as a threaded bolt, is rotated in an adjusting thread 32a about an axis of movement BA and moves in this way in FIG. 6 from the right side to the left side. A contacting portion 34a slides thereby on a counter-contacting portion 24 and lifts the entire basic body 30 in relation to the roller module 20. And as the sliding door 110 is attached to the basic body 30, the sliding door 110 is thereby lifted as well. Instead of a spherically shaped head another embodiment, in particular conical or truncated is conceivable.

(18) FIG. 7 illustrates a solution, which exclusively provides a displacement, in particular in a linear way, as the adjusting movement. In this case, a linear guide is provided at the basic body 30, along which the first adjusting means 32 is pushed. The full contact between the contacting portion 34 and the counter-contacting portion 24 results in mutual sliding on each other and thereby likewise in a lifting of the basic body 30.

(19) FIG. 8 illustrates a purely rotary solution of the first adjusting means 32, which by means of an eccentric head and rotary sliding of the contacting portion 34 on the counter-contacting portion 24 likewise provides the lifting of the basic body 30 in relation to the roller module 20, as already described several times.

(20) The above explanation of the embodiments describes the present disclosure exclusively based on examples. Obviously, individual features of the embodiments, as long as technically reasonable, can be combined independently of each other without leaving the scope of the present disclosure.
