Description

The present invention relates to a carriage for a sliding door system of a shower and a component assembly with a carriage.

So-called carriages for sliding door systems of a shower are generally known in the prior art. Such carriages generally have a base body with a bearing section for storing a shower door clamp, on which a sliding door leaf, usually a glass sliding door leaf, is clamped. Carriages furthermore have a sliding section for slidably mounting the carriage on a holding body for holding the shower door clamp, including the sliding door leaf clamped therein, by means of the carriage. The holding body is mounted, for example, on a frame body or on a further holding body, on or with which the shower is to be installed.

US4611436 A describes a sliding door arrangement for bathtubs, shower cubicles and the like.

It is always difficult to provide a carriage or component assembly in which the carriage is slidably mounted on the holding body with as little friction as possible and nevertheless provides adequate protection against dirt that could penetrate into the carriage between the carriage and the holding body can be.

The object of the present invention is to at least partially remedy the disadvantages described above. In particular, it is an object of the present invention to provide a carriage and a component assembly for a sliding door system for a shower, the carriage being displaceably mountable on a holding body with as little friction as possible and nevertheless providing adequate protection against dirt which is between the carriage and the holding body could penetrate into the carriage, can be realized.

The above object is solved by the features of the independent claims. Advantageous configurations are described by the subclaims. Further features and details of the invention emerge from the description and the drawings. Features and details that are described in connection with the carriage also apply, of course, in connection with the component assembly according to the invention and vice versa, so that with respect to the disclosure of the individual aspects of the invention, reference can always be made to one another.

According to a first aspect of the present invention, a carriage for a component assembly for a sliding door system of a shower is provided. The carriage has a base body with a bearing section for storing a shower door clamp. In addition, the carriage has a sliding section for displaceably supporting the carriage on a holding body for holding the shower door clamp, including a sliding door leaf clamped therein, by means of the carriage. At least one first slide bearing, at least one second slide bearing and at least one roller are arranged along the slide section, the at least one Roller is arranged on the sliding section before the at least one first sliding bearing and after the at least one second sliding bearing.

The two slide bearings, which are arranged in front of and behind the at least one roller, or the roller, which is arranged between the two slide bearings, not only enable low-friction sliding of the carriage on the holding body, but also reliable protection against moisture and dirt or deposits that can adhere to the holding body can be realized. Moisture and dirt or deposits, which are located on the holding body, are always removed from the slide bearings, which are located in the respective direction of displacement of the sliding door leaf in front of the roller, before the dirt or deposits can reach the at least one roller.

An arrangement of the roller between the two sliding bearings is to be understood as an arrangement at least in a projection of the roller between the two sliding bearings. This means that the two plain bearings and the at least one roller do not have to be arranged in alignment with one another or, in practice, are not.

According to a development of the present invention, it is possible that in a carriage the at least one first slide bearing, the at least one second slide bearing, and / or the at least one roller consist of plastic or consist essentially of plastic. As a result, the carriage can be manufactured inexpensively. A plastic plain bearing can also be replaced easily and inexpensively. In addition, a plain bearing made of plastic makes it easy Realize press fit or at least a close contact between the encompassing surface and the tread. This allows the plain bearing serve as a kind of seal and / or dirt scraper on the tread. Furthermore, moisture and chemicals can be easily removed from a tread of the holding body. In addition, a particularly easy and safe running of the sliding door leaf or the carriage is achieved.

Furthermore, it is possible that, in a carriage according to the invention, the at least one first slide bearing and the at least one second slide bearing each have, at least in some areas, a C-shaped gripping surface for gripping around a running surface of a running profile of the holding body that is complementary or essentially complementary to the respective gripping surface, the gripping surfaces each have a gripping angle of more than 180 °. Due to the sliding section or the gripping surface with the gripping angle of more than 180 °, the trolley can be rotated or pivoted about its longitudinal axis so that the running profile is arranged in such a way that the trolley is prevented from being lifted out of the running profile. This results in simple assembly by rotating the carriage to the shower door clamp to be used, with the sliding door leaf clamped therein, which is designed, for example, as a glass pane, so that the bearing section and the shower door clamp on the sliding door are approximately at the same height. The sliding door, for example the glass pane in the form of a shower door, is then inserted into the bearing section on the carriage and pivoted back into a functional position by a rotating movement of the carriage. In addition, a particularly good sealing and stripping effect between the carriage and the holding body can be achieved by the gripping.

In the context of the present invention, it is furthermore possible for a rolling surface of the at least one running roller in a carriage has the same or substantially the same inner radius as the at least one first slide bearing or a gripping surface of the at least one first sliding bearing and the at least one second sliding bearing or a gripping surface of the at least one second sliding bearing. As a result, both the sealing or wiping effect and the low-friction displacement between the carriage and the holding body can be advantageously influenced. In addition, a quiet and correspondingly low-wear running of the carriage on or on the holding body can be achieved.

Furthermore, it can be advantageous if, in a carriage according to the invention, the bearing section is arranged on a first end region of the base body, which faces away from a second end region of the base body, on which the sliding section is located, and a recess for receiving and storing at least in sections the shower door clamp. As a result, the shower door clamp can be inserted particularly easily into the carriage or into the bearing section of the carriage.

Furthermore, in a carriage according to the invention it is possible for the bearing section to be a monolithic component of the base body. Since various individual parts that would have to be brought together are dispensed with with respect to the bearing section, a particularly inexpensive and reliably functioning bearing section can be provided

According to a further aspect of the present invention, a component assembly for a sliding door system of a shower is made available. The component assembly has a carriage as described in detail above. In addition, the component assembly has one Holding body for holding a shower door clamp including a sliding door leaf clamped therein by means of the carriage, the holding body having a running profile with a running surface and the C-shaped gripping surface of the first sliding bearing and the C-shaped gripping surface of the second sliding bearing the running surface, which is complementary or at least in sections is designed essentially complementary to the gripping surfaces, gripping each with a gripping angle of more than 180 °. A component assembly according to the invention thus brings with it the same advantages as have been described in detail with reference to the carriage according to the invention. In particular, the C-shaped gripping can achieve a high level of tightness or an advantageous dirt and moisture wiping effect. It is possible here that, in a component assembly according to the invention, the encompassing surface and the running surface are arranged and configured in a form-fitting manner, at least in sections, in particular in the form of an interference fit. As a result, moisture and / or dirt or deposits on the holding body or on the running surface of the holding body can be removed particularly effectively from the running surface when the carriage is moved on the running surface.
