Trolley for a sliding door system of a shower and set of components

The present invention relates to a trolley for a sliding door system of a shower as well as to a set of components with a trolley.

So-called trolleys for shower sliding door systems are generally known in the state of the art. Trolleys of this type generally have a base body with a support section for supporting a shower door clamping element in which a sliding door leaf, generally a glass sliding door leaf, is clamped. . In addition, the trolleys have a sliding section for the sliding support of the trolley in a clamping body for clamping the shower door clamping element, including the clamping sliding door leaf, by means of the rolling carriage. The holding body is mounted for example on a frame body or on a further holding body, in or with which the shower is to be installed.

US4611436A describes a sliding door arrangement for bathtubs, shower stalls and the like.

It is always difficult to provide a trolley or a set of components in which the trolley is supported on the clamping body with as little friction as possible and yet sufficient protection can be realized against dirt entering the trolley. and the clamping body could enter the trolley.

The present invention has the object of eliminating at least in part the disadvantages described above. Especially, the present invention has the object of providing a trolley as well as a set of components for a sliding door system for a shower, the trolley being able to be supported on a clamping body with the least possible friction, and being able to be realized however sufficient protection against dirt that between the trolley and the clamping body could enter the trolley. The above-mentioned object is achieved by the features of the independent claims. Advantageous embodiments are described in the dependent claims. More characteristics and details of the invention appear from the description and the drawings. The characteristics and details described in relation to the trolley are obviously also valid in relation to the set of components according to the invention and vice versa respectively, so that with respect to the description relating to the various aspects of the invention it can be make or are referenced reciprocally.

According to a first aspect of the present invention there is provided a trolley for a set of components for a sliding door system of a shower. The trolley has a base body with a support section for supporting a shower door fastener. Furthermore, the trolley has a sliding section for the sliding support of the trolley in a clamping body for clamping the shower door clamping element, including a sliding door leaf clamped within it. , by means of the trolley. Along the slide section, at least one first slide bearing, at least one second slide bearing, at least one second slide bearing, as well as at least one track roller are arranged, the at least one roller being arranged of rolling in the slide section before the at least one first slide bearing and after the at least one second slide bearing.

By means of the two plain bearings which are arranged in front of and behind the at least one track roller and by means of the track roll which is arranged between the two plain bearings, it is possible to achieve not only low-friction sliding of the carriage on the clamping body, but also a reliable protection against moisture and dirt or deposits that can adhere to the clamping body. Moisture and dirt or deposits that are on the clamping body are always removed by the sliding bearings, which in the respective sliding direction of the sliding door leaf are respectively in front of the roller, before the dirt or deposits can reach at least one track roller.

By an arrangement of the roller between the two sliding bearings is meant an arrangement at least in one projection of the roller between the two sliding bearings. In other words, the two slide bearings and the at least one track roller do not have to be arranged in alignment with each other and in practice they are not either.

According to a variant of the present invention it is possible that in a rolling carriage, the at least one first sliding bearing, the at least one second sliding bearing and / or the at least one rolling roller are made of synthetic material or are composed substantially of synthetic matter. In this way, the trolley can be manufactured inexpensively. A plain bearing made of synthetic material can also easily and economically exchangeable. Furthermore, by means of a plain bearing made of synthetic material, a simple press fit or at least intimate contact between the gripping surface and the running surface can be realized. In this way, the plain bearing can serve as a kind of seal and / or dirt scraper on the running surface. Furthermore, moisture and chemicals can be easily removed from a running surface of the clamping body. Furthermore, in this way a particularly easy and safe rolling of the sliding door leaf or the trolley is achieved.

Furthermore, it is possible that in a rolling carriage according to the invention, the at least one first plain bearing and the at least one second plain bearing each have at least in areas a C-shaped gripping surface for gripping a bearing surface. rolling, carried out at least in sections complementary or substantially complementary to the respective gripping surface, of a rolling profile of the clamping body, the gripping surfaces respectively having a gripping angle of more than 180 °. By means of the sliding section or the gripping surface with the gripping angle of more than 180 °, the roller carriage is rotatably or pivotally arranged around its longitudinal axis wrapping the running profile in such a way as to prevent the trolley is lifted out of the running profile. In this way, a simple assembly results in such a way that the trolley is rotated towards the shower door grip fastening element with the sliding door leaf clamped inside it and realized for example as glass, of such that the support section and the shower door clamping element are on the sliding door at approximately the same height. Then, the sliding door, for example the glass in the form of a shower door, is inserted into the support section on the trolley and, by means of a turning movement of the trolley, it is pivoted backwards, at a functional position. Furthermore, by gripping, a particularly good sealing and scraping effect can be achieved between the carriage and the clamping body.

Within the framework of the present invention, it is furthermore possible that in a running gear, a running surface of the at least one running roller has the same or substantially the same inner radius as the at least one first sliding bearing or a surface grip of the at least one first slide bearing and that the at least one second slide bearing or a gripping surface of the at least one second slide bearing. In this way, both the sealing or scraping effect and the low-friction sliding between the carriage and the clamping body can be advantageously influenced. Furthermore, in this way, a smooth running and thus little wear of the running gear on or on the clamping body can be achieved.

Furthermore, it may be advantageous if, in a trolley according to the invention, the clamping section is arranged in a first front area of the base body, which is opposite a second front area of the base body in which the sliding section is located. , presenting a recess to receive and support the shower door clamping element at least in sections. In this way, the shower door clamping element can be inserted particularly easily into the trolley or into the carrier section of the trolley.

Furthermore, in a trolley according to the invention it is possible for the support section to be a monolithic integral part of the base body. Since various individual parts which would have to be assembled are dispensed with with respect to the support section, it is possible to provide a particularly economical and reliable operating support section.

According to another aspect of the present invention there is provided a set of components for a shower door system of a shower. The set of components has a trolley as described in detail above. Furthermore, the set of components has a clamping body for holding a shower door clamping element, including a sliding door leaf clamped therein, by means of the rolling carriage, where the clamping body has a tread profile with one running surface, and the C-shaped gripping surface of the first plain bearing as well as the C-shaped gripping surface of the second plain bearing grip, respectively with a gripping angle of more than 180 °, the rolling surface that is made at least in sections complementary or substantially complementary to the gripping surfaces. In this way, the set of components according to the invention offers the same advantages that have been described in detail with reference to the trolley according to the invention. In particular, the C-shaped grip can achieve high sealing or an advantageous scraping effect against dirt and moisture. It is possible that in a set of components according to the invention, the gripping surface and the running surface are made to be in contact with each other by geometric connection at least in sections, especially in the form of a press fit. In this way, by means of the running gear, moisture and / or dirt or deposits on the clamping body or the running surface of the clamping body can be removed particularly efficiently from the running surface during a sliding of the slide. bearing on the tread surface.
