Description

The invention relates to a roller carriage for guiding a displaceable wing in a guide rail, with a base body to which the wing is attached hanging, and with a bearing in the main body support roller unit with at least two support rollers, which are each rotatably mounted about a rotation axis and at least one Tread of the guide rail interact. Roller carriages of this type are used in particular for sliding door systems.

There are already known roller carriages of the aforementioned type, in which the vertical position of the wing is adjustable via eccentric. As a rule, these roller carriages have two individual carrying rollers, which are arranged next to one another via individual eccentric bolts. However, such roller carriages do not ensure that, in particular, even after a respective adjustment of the wing position, both support rollers always remain in the desired manner in the guide profile of the guide rail, which has an adverse effect on the function and the service life of the carriages.

The invention has for its object to provide a roller carriage of the type mentioned above, which not only has a very compact and robust construction, but in which it is also ensured that over the rollers always a uniform load transfer to the guide rail.

This object is achieved by a roller carriage with the features of claim 1. Preferred embodiments of the roller carriage according to the invention will become apparent from the dependent claims, the following description and the drawings.

The roller carriage according to the invention serves to guide a sliding wing in a guide rail and comprises a base body to which the wing is attached hanging, and mounted in the base support roller unit with at least two support rollers, which are each rotatably mounted about a rotation axis and with at least one tread Collaborate guide rail. The support rollers are rotatably mounted in the region of opposite ends of a support roller carrier of the support roller unit. The carrier is centered, i. in the central region between the two support rollers, oscillating about an eccentric axis, which is arranged eccentrically to a bearing axis, via which the support roller unit is mounted in the base body.

Due to this design results in an extremely compact and robust construction of the roller carriage, with which not only the wing vertically adjustable, but in particular it is ensured that on the rollers is always a uniform load transfer to the guide rail. Thus, the roller carriage according to the invention is particularly suitable for guiding wings of higher weight, in which the most uniform load transfer on the bearing rollers comes particularly to fruition.

A vertical adjustment of the wing can be done in particular by turning the bearing axis, which accordingly also the eccentric axis and the protective disk are rotated. After a respective setting of the desired wing position, the bearing axis can be set, for example via a nut for countering against the body.

Preferably, on the eccentric axis serving as Aushebeschutz serving to lift the wing from the running rail protection disc rotatably disposed, whereby always a reliable protection against lifting of the wing or the roller carriage is ensured from the running rail. After the protective disc is rotatably mounted on the eccentric axis, with a respective vertical adjustment of the wing by turning the bearing axis to ensure the Aushebeschutzes also the protective disk rotated accordingly.

In this case, the protective pane is preferably designed and dimensioned so that it is limited depending on the rotational position of the eccentric axis, which is adjustable in particular on the bearing axis, raising the support roller unit against a web or the like of the running rail or a lifting of the support roller unit from the running rail or allows the suspension of the support roller unit in the running rail in a defined mounting position. Conveniently, the protective disk for lifting or hanging the wing or the support roller unit is provided in a limited peripheral region with a recess.

The carrying rollers may in particular be provided in each case as a single or double roles. In particular, they can be recessed in a track of the track, wherein they can not be dug out of the track during normal operation due to the corresponding rotational position engaging protective disc, since the outer diameter of the protective disc lifting the support roller assembly, for example, against an upper horizontal web or the like the running rail limited.

In contrast, in a mounting position, a hanging and unhooking of the sliding leaf is possible by the protective screen is rotated to a position in which the recess of the protective disk opposite the respective upper web or the like of the running rail. As a result, the support roller carrier can be lifted with the support rollers to the web zoom, so that the support rollers can get out of the depression of the track and the support roller assembly taken out laterally or can be used in this setting.

The recess of the protective disk can be provided, for example, in the form of a straight section formed by a chord.

The combination of the Exzenterverstellung with the Aushebeschutz in the form of a protective plate with a provided only in a limited peripheral area recess is particularly advantageous because after mounting the support roller carrier in the mounting position of the protective disc already a small rotation of the eccentric axis for adjusting the vertical position of the wing immediately also causes a corresponding rotation of the protective plate, whereby its recess is rotated out of its position relative to the web of the track, so then immediately the web opposite peripheral portion of the protective disk larger outer diameter limits lifting of the support rollers and the support roller carrier and thus lifting the wing the guide rail is prevented.

The protective disk is preferably set on the eccentric axis such that the recess or the chord of the protective disk lies parallel to the plane through the center axes of the eccentric axis and the bearing axis.

It is particularly advantageous if the center axes of the support rollers and the center axis of the eccentric axis lie in a common plane.

The vertical distance of the chord of the circle to the central axis of the eccentric axis is expediently less than or equal to the radius of the support rollers. This ensures that the support rollers can be raised in the mounting position of the support roller carrier or the protective plate up to the upper web of the track.

As already mentioned, by means of a rotation of the bearing axis effected via a corresponding rotation or adjustment of the eccentric axis for adjusting the vertical position of the wing, it is preferably simultaneously possible to activate the lifting protection via the protective pane as well. According to an expedient practical embodiment of the roller carriage according to the invention, the eccentric axis and the bearing axis are made in one piece, which brings a simpler structure with it.

The bearing axis is expediently provided with a receptacle for a tool, for example an Allen wrench or the like, and, for example, with an external thread for a nut for countering the bearing axis on the base body. By means of the tool in question, the bearing axis and, correspondingly, the eccentric axis and thus simultaneously also the protective disk can be rotated or adjusted in the desired manner.
