Description

The present invention relates to a roller carriage for receiving a sliding door and a sliding door system, having at least one roller carriage according to the invention.

It is known that sliding doors are used to cover and open door openings in structurally cramped situations. Such sliding doors are usually provided with door leaves which are attached to a roller carriage. One or more roller carriages are provided in order to move the sliding door back and forth between a locking position and an opening position. For this movement, the roller carriage is mounted in a roller track and is received there in a movable manner, in particular with rotary bearing means. For the movement it is now necessary that at least a small movement gap remains, through which the door leaf of the sliding door extends downwards and thus the movement is released.

The disadvantage of the known solutions is that the open movement gap for the sliding door is visible from below as an open gap during the movement in different positions of the roller carriage or the sliding door. If, for example, the sliding door is in the closed position, the user can regularly see the technology of the sliding door system from the outside, which adversely affects the overall aesthetic character of such a sliding door system. In addition, one is in this position mechanical influence or a soiling influence on the internal technology of the sliding door system is possible. Also disclosed U.S. 4,424,605 a sliding door system with a roller carriage for receiving a sliding door and with a screen attached to the door which has a screen section with an extension along the direction of displacement of the roller module for covering the roller module, wherein the screen section extends along the direction of movement of the roller module over the roller module and the Base body also extends.

It is the object of the present invention to at least partially remedy the disadvantages described above. In particular, it is the object of the present invention to be able to provide better protection against soiling without impairing the function in a cost-effective and simple manner.

The above object is achieved by a roller carriage with the features of claim 1 and a sliding door system with the features of claim 10. Further features and details of the invention emerge from the subclaims, the description and the drawings. Features and details that are described in connection with the roller carriage according to the invention naturally also apply in connection with the sliding door system according to the invention and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is or can always be made to each other.

A roller carriage according to the invention is used to accommodate a sliding door and has a roller module for slidable attachment to a roller track. A base body is also provided for attachment to the sliding door. A roller carriage according to the invention is characterized in that this roller carriage has a screen for a joint movement with the roller module. The screen has a screen portion with an extension along the direction of displacement of the roller module for covering the Roller module and / or the base body, the panel section extending along the direction of displacement of the roller module beyond the roller module and the base body.

In this way, the screen is always in the desired position and thus leads to the movement gap being covered by the movement. The screen can cover both the area in which the sliding door is attached to the roller carriage and a surrounding area. For example, it is possible that the screen has corresponding cutouts through which the door leaves of the sliding door can extend to the roller carriage or in particular to the base body.

The screen now serves to prevent the sliding door system from being viewed from below, preferably in any position of the roller carriage. In addition, the screen prevents dust and other dirt from entering the different positions of the roller carriage. Also a mechanical action or Damage due to the penetration of solid components is effectively avoided by the screen, in particular by the corresponding alignment of the screen section. The extension along the direction of displacement is particularly flat. It is preferred if the diaphragm section is designed at least in sections as a flat surface. An extension along the direction of displacement of such a flat surface is therefore preferably aligned parallel to the direction of displacement.

It can be advantageous if, in a roller carriage according to the invention, the screen is designed as a separate component from the roller module and the base body and has a fastening section for fastening to the roller module and / or the base body. Subsequent attachment of this functional element designed as a separate component in the form of the screen is thus also possible. Last but not least, the assembly is simplified in this way, since this can be carried out in the usual way. Finally, the movement gap is closed or at least partially covered by fastening the screen with the aid of the fastening section. Last but not least, the attachment to the roller module and / or the base body is preferably reversible. For example, screws can be used to provide this fastening step. This makes it possible to ensure accessibility even after assembly, in order to be able to intervene in the sliding door system for maintenance work or repair work, for example.

It can be a further advantage if, in a roller carriage according to the invention, the fastening section has at least one fastening means for fastening the screen to the roller module and / or the Has base body. A fastening means can be designed, for example, in the shape of a pin, in particular with an external thread. However, plug-in systems or snap-lock devices can also be provided as fastening means within the meaning of the present invention. It is preferred if the at least one fastening means is designed as a reversibly acting fastening means for multiple fastening and loosening of the fastening. Two or more fastening means can preferably also be provided, which additionally fulfill a positioning functionality. The fastening section is thus positioned in an exact manner relative to the roller carriage in preferably all three orientations. Due to the fixed connection between the fastening section and the panel section, this positioning function accordingly also applies to the panel section and thus the function of this panel section.

A further advantage can be if, in a roller carriage according to the invention, the at least one fastening means has a fastening axis which extends transversely, in particular perpendicular, to the direction of displacement of the roller module. This is to be understood as the fact that the fastening means can be reached in particular from a front side and thus easily accessible in this way. If the fastening means is provided, for example, with a fastening axis in the form of a threaded axis or a screw axis, a corresponding assembly aid, for example in the form of a screwdriver, can simply be attached from the front. In this way, both the opening and the closing are reversibly simplified, so that the functionality of a separate design of the panel section or the screen becomes even more apparent.

Another advantage is when, in a roller carriage according to the invention, the fastening section and the panel section enclose an angle of less than 140 ° and more than 60 °, in particular in the range of 80 ° and 100 °. The fastening section and the panel section are preferably perpendicular to one another, in particular in the range of ± approximately 5 °. On the one hand, this facilitates attachment and use and, at the same time, improves the panel function. The dimensions for the required installation space are also significantly reduced. The fastening section and panel section are preferably flat, in particular in a planar manner.

It is also advantageous if, in a roller carriage according to the invention, the screen is formed in one piece with the roller module and / or with the base body. It is of course also conceivable that part of the screen can be formed in one piece and another part can be formed separately from the roller module and / or from the base body. The one-piece design with the roller module reduces the complexity of the assembly. In particular, an additional assembly step can be dispensed with. Production and storage are also reduced in terms of their complexity by reducing the number of components reduced in this way. Ultimately, further costs and assembly complexity can be saved in this way.

It is a further advantage if, in a roller carriage according to the invention, at least the screen section extends along the direction of displacement of the roller module beyond the roller module and the base body. In particular, this is the case on both sides of the roller module. If, for example, a plurality of two or more roller carriages are provided in order to fasten a sliding door, the panel section preferably extends over all of them Roller carriages in the direction of the shifting direction to ensure the screen function over the entire section of the sliding door. In addition to the basic protective effect for the movement gap in the sliding door system, this also provides an improved protective effect for the roller module or the roller carriage itself. In particular, this again relates to a flat, preferably flat panel section within the meaning of the present invention.

In the case of a roller carriage according to the preceding paragraph, it can be advantageous if a visual axis with a viewing angle between the visual axis and the diaphragm section of less than 45 ° is formed between a terminating edge of the screen section in the direction of displacement of the roller module and an upper terminating edge of the roller carriage. In other words, viewing from the side is made more difficult, the smaller this viewing angle is. From a structural point of view, the viewing angle is preferably above approximately 10 °, preferably above approximately 15 °. The viewing angle is preferably in the range between 25 ° and 35 °. The sight angle is in particular formed at an acute angle. The respective terminating edge can be understood to mean both a material-defined edge and a virtual edge which is defined by the furthest protruding extension of the respective component.

According to the invention, it is also advantageous if, in a roller carriage according to the invention, the panel section extends transversely to the direction of displacement of the roller module beyond the roller module and the base body. While in the embodiment described above, an extension along the direction of displacement was decisive, an extension transverse to the direction of displacement is now also advantageous, since in this way the Movement gap is covered in its width. An improvement similar to that in the embodiment according to the preceding paragraphs is therefore preferably produced. The correlation with a surrounding cladding of the roller track relates to a reduction in the remaining gap that forms. The remaining gap is preferably reduced to less than approx. 10 mm, in particular to less than approx. 5 mm. It can even be preferred if the screen section overlaps with a part of the lining of the roller track and in this way the remaining gap in this section is completely eliminated. The present invention also relates to a sliding door system, having a roller track and at least one roller carriage according to the present invention, which is slidably mounted in the roller track. The sliding door system according to the invention thus also brings the same advantages as have been explained in detail with reference to a roller carriage according to the invention.

A sliding door system according to the invention can be developed to the effect that at least one sliding door by means of at least two Roller carriage with the features of the present invention is slidably mounted in the roller track. Particularly in the case of heavy or wide door leaves of the sliding door, a secure fastening of the sliding door with little play can be ensured in this way.

It can also be advantageous if, in a sliding door system according to the invention, at least two door leaves of a sliding door are fastened to at least one roller carriage according to the present invention. The screens of the two roller carriages are spaced from one another perpendicular to the direction of displacement of the roller modules of the two roller carriages at least by the wall thickness of the screen section of one of the two screens. A design of a sliding door with two door leaves is also to be understood as a telescopic design. A door leaf is moved faster and can therefore be described as a fast runner. The slower door leaf can also be called a slow runner. Due to the offset in a vertical orientation, that is to say in the direction of gravity, for the two separate screens it is now possible for them to also move telescopically into an overlapping position. This ensures that the movement gap is covered even better, and at the same time the freedom of movement is not impaired by the telescopic design of the correlating screens. In particular, there is a movement gap between these two screens in order to avoid jamming or rubbing in contact with one another with a high probability.

Further advantages, features and details of the invention emerge from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings.

In Fig. 1 a situation is shown in which a sliding door system 100 with a sliding door 110 is equipped with a door leaf 112. The door leaf 112 is attached to two roller carriages 10 and is supported in this way in a roller track 120 (not shown). A screen 40 is attached to both roller carriages 10 via corresponding attachment sections 44 with attachment means 44a. The fastening axes BA of the fastening means 44a extend transversely to the displacement direction VR. In this way, there is improved, in particular frontal, accessibility. The fastening means 44a are designed here as fastening screws, so that the alignment according to the invention of the fastening axes BA enables easier access with an assembly aid, that is to say, for example, with a screwdriver.

For the movement of the sliding door 110 between an open and a closed position, a corresponding mounting of the roller carriage 10 is provided. Especially in Fig. 2 the division between the roller module 20 and the base body 30 can be clearly seen. The roller carriage 10 is equipped on the roller module 20 with rotatable bearing means 22 in the form of rollers. These rollers run in a roller track 120, which is part of the sliding door system 110 here.

As from the Fig. 2 As can also be seen clearly, the screen 40 is provided with a screen section 42 in addition to the fastening section 44. The screen section 42 and the fastening section 44 are essentially perpendicular to one another. By attaching the screen 40 to the two roller carriages 10, a joint movement with the two roller carriages 10 now takes place. If the sliding door 110 is moved along the displacement direction VR, the roller carriages 10 and thus the screen 40 also move due to the corresponding fastening options. Viewing from below, that is, against the direction of gravity SKR, is made more difficult or even avoided in this way. In particular, a direct influence of dust or other soiling on the roller carriages 10 is essentially excluded by the corresponding screen 40.

In Fig. 3 a situation is shown in which a second door leaf 114 is also provided. Here, both door leaves 112 and 114 of the sliding door 110 are preferably each attached to two roller carriages 10. Thus, in principle, the technical implementation doubles as it already has Fig. 1 shows. Preferably, each of the roller carriages 10 can have a corresponding screen 40, which, however, are arranged at a distance from one another in the direction of gravity SKR are in order to be able to carry out a correlation movement in an overlapping or telescoping manner.

Fig. 4 shows that it can be preferred if the screen section 42 of the screen 40 extends along the displacement direction VR beyond the respective roller carriage 10. This leads to an improved protective effect and reduced inspection. In particular, the extent is such that a viewing angle β according to the invention of less than approximately 45 ° is formed. In the execution of the Fig. 4 Different viewing angles β are provided for the two ends of the diaphragm section 42. It can be seen here that the respective terminating edge 42a of the panel section 42 can form a corresponding angle with the associated upper terminating edge 10a of the roller carriage 10, which according to the invention is defined as viewing angle β.

The above explanation of the embodiments describes the present invention exclusively in the context of examples. Of course, individual features of the embodiments can be freely combined with one another, provided that they are technically sensible, without departing from the scope of the present invention defined by the claims.
