Description

The invention relates to an arrangement for a shower enclosure with a sliding door system according to the preamble of claim 1.

For use in shower cubicle such arrangements must be designed so that the forces can be absorbed (eg housing made of metal, not plastic), at the same time the necessary tolerances must be maintained in the guide to ensure a backlash-free running or be appropriate Surface properties (surface texture, stainless) needed. Furthermore, the design freedom required in the shower cubicle construction must be ensured.

Commonly used aluminum extrusion profiles can not guarantee the necessary precision and surface properties, since they are often made of too soft aluminum and the often complex shapes negatively affect the precision. Furthermore, sliding doors or sliding doors are structurally almost exclusively equipped with plastic rollers or plastic-coated metal rollers or glides in the shower cubicle construction.

• Es ist nicht möglich, spielfreie Türen zu konstruieren, was sich letztendlich in der Bewegung durch Klappern und anderweitige unangenehme Geräusche äußert. Ferner neigt ein Duschenflügel im Moment des Anschlages immer zum Kippen. Daraus folgen noch höhere unangenehmere Geräuschentwicklungen, und auf Dauer eine unnötige Beanspruchung und/oder Verkürzung der Lebensdauer bzw. der Pflegeintervalle der Schiebeeinheit. Mit zunehmendem Alter der Duschkabine werden diese Geräusche immer lauter, weil die Kunststoffrollen verschleißen und in ihrer Rundheit abbauen, das Material verhärtet (Rollen brechen), eventuell verbaute Kugellager gehen kaputt. Vieler dieser Laufrollen müssen ausgetauscht werden, weil sie aus den verschiedensten oben genannten Gründen nicht mehr wunschgemäß funktionieren.

These designs are partly quite inexpensive, but also have disadvantages:

• It is not possible to construct backlash-free doors, which ultimately manifests itself in movement through rattling and other unpleasant noises. Furthermore, a shower wing always tilts at the moment of the stop. This results in even higher unpleasant noise developments, and in the long term an unnecessary stress and / or shortening of the service life or care intervals of the sliding unit. With increasing age of the shower cubicle, these noises become louder and louder, because the plastic rollers wear out and break down in their roundness, the material hardens (rolls break), possibly installed ball bearings are broken. Many of these rollers must be replaced because they do not function as desired for a variety of reasons above.

In the DE 94 18 019 U1 discloses a curved shower stall wall sliding on adjustable castors. The rollers are adjustable so that they can better follow the shape of the rail during their sliding movement. For this purpose, the rollers are pivotable about a vertical axis during the sliding movement. The rollers are connected via a pin directly to the sliding door.

From the FR 2 333 926 A1 is a partition wall for shower cubicles known. The partition wall comprises three sliding wall panels which are suspended in an upper sliding or roller guide rail and are guided freely suspended with guide rails on a lower guide body, wherein each wall panel is held by magnetic force transverse to the board plane at an associated surface of the guide body and guided thereon ,

Out DE 296 18 205 U1 For example, a shower enclosure is known with at least one fixed wing or vertically mounted wing and at least one horizontally mounted, second wing connected thereto, which can perform a relative movement to the first wing by force. Here cooperating guide rails with support and guide rollers are used, which lead to the disadvantages described above.

Out DE 20 2011 003 596 U1 is a sliding door system with a wall element and a first sliding door, which is displaceable in a movement parallel to the plane of the wall element is known. In the upper part, the weight of the wall and door elements are absorbed by suspensions and in the lower part of the sliding door system, a guide rail is provided. In this case, a carriage of a first linear guide is fixedly arranged on the wall element and a rail of the first linear guide is fixedly arranged on the first sliding door. The fixed carriage comprises a base, on the upper side of which at least one rotatable roller is arranged, the axis of rotation of which runs in the plane of movement of the sliding door to be guided. The rail of the leading sliding door has a flank, by means of which, when placed against the cylinder surface of the roller, the guidance in the movement is made possible.

Out DE 171979 a suspension device for sliding doors is known, in which the sliding door is suspended on a slidably disposed between two fixed rails, mediation of balls or the like. Slides. It is therefore disclosed a bearing on balls for a carriage, wherein the balls are kept stationary in holes provided in rods, resulting in considerable friction and corresponding noise.

Out DE 10 2006 062 287 A1 an arrangement for a shower enclosure is known, which includes all the features of the preamble of claim 1.

The object of the present invention is therefore to present a further arrangement of the above-mentioned type, which is suitable to avoid the disadvantages of some of the arrangements described above.

According to the invention, this object is solved by the features of claim 1. Advantageous developments of the invention are contained in the subclaims. Accordingly, the present invention relates to an arrangement for a shower enclosure with a sliding door system with at least one wall element and at least one sliding door, wherein the wall element and the sliding door between an upper and a lower carrier profile are arranged and in the upper and lower carrier profile rails for a guide Sliding door are provided in the displacement. It is provided that in each case at least one ball carriage is slidably mounted in the rails and the sliding door is connected directly or indirectly with the ball rolling carriage. The sliding door is directly or indirectly connected to the ball track carriage in the area of the upper running rail and floating in the area of the lower running track with the ball rolling carriage. In this case, the floating attachment of the sliding door with the ball carriage in the lower region of the running rail via a connection with magnetic force. In the region of the lower running rail, the sliding door has at least one magnet which is in an operative relationship with the ball-rolling carriage provided in the lower region of the running rail for displacing and / or pivoting the sliding door.

An advantageous feature of the invention describes the design of the ball rolling cart, which is preferably formed from a molded part with two circulating in guides ball chains. The ball chains are circumferentially arranged in guides and occur at least partially free in the area of the top and bottom of the molding, with a guide in the movement is made possible by contact with the rails provided in the support rails.

In the Fig. 1 an arrangement for a shower enclosure 1 with a sliding door system with a wall element 2 and a sliding door 3 is shown. The wall element and the sliding door are arranged between an upper and a lower carrier profile 4, 5 between the vertical profiles 10, 20. Wall and door elements have vertical frame profiles in this example. In the upper and lower support profiles 4, 5 each rails 6, 6 'are integrated for a guide of the sliding door 3 during its displacement. In the rails 6, 6 'are each a ball carriage 7, 7' slidably mounted, wherein the sliding door 3 with the ball carriage 7, 7 'is connected. It is preferably provided that an already prefabricated track from a suitable aluminum alloy or other suitable metal (eg stainless steel rail) is introduced into a shower tray carrier profile, so that on the one hand the necessary Designfreit retains, as well as the necessary degree of accuracy for a durable, backlash-free Functioning of the ball carriage.

The ball slide or the rail guide can be made of a variety of materials and shapes, if they have the necessary characteristics described (precision and surface finish).

In the present embodiment ( Fig. 3 to 5 ), the connection of the sliding door 3 with the upper ball carriage 7 via a provided on the upper ball carriage 7 suspension 7.5 and the screws 7.6 and a pivot mechanism 3.2, with the door 3 itself or a fitting (not shown) or the vertical frame profile 3.1 of the door 3 is connected. The ball carriage 7 is in a front view in the Fig. 2 shown. The sliding door (above), is screwed directly or indirectly to the respective ball truck, hung and secured or clamped and secured, there can also take place a height adjustment, for example on the slots 7.8.

The ball carriage 7 consists of a molded part with circulating in the molded part between guides ball chains 7.1, 7.2. The ball chains 7.1, 7.2 occur in sections at the top and bottom of the molding sections and are free to move in the rails 6, 6 'formed.

In the Fig. 6 to 8 Views are shown in the region of the lower carrier profile of the arrangement. The connection of the sliding door 3 with the ball carriage 7 'in the lower region of the running rail 6' is done here "floating" via a connection by means of magnetic force. For this purpose, it is provided that the sliding door 3 in the region of the lower running rail 6 'has at least one magnet 8 which is in an operative relationship with the sliding carriage 7' provided in the lower region of the running rail 6 'for moving and pivoting the sliding door 3. This can advantageously compensate for changing tolerances when opening and closing noiseless. The prerequisite is that the magnet and a responsive material for the magnet act in interaction.

On the one hand, the magnet keeps the door free of play on the ball carriage, on the other hand the shear forces of the connection (for example magnet / metal) are not so great that no displacement can take place between the carriage and the door wing and thus tolerances in all directions can be compensated.

The magnetic holding forces are to be chosen so that a folding away of the door leaf for cleaning purposes, for example, by hand is possible and the door in the utility function (back and forth) does not solve. But this can also be done by a holder with spring force in an equivalent manner, which is not explicitly shown in the present example. Advantageously, the swinging away of the wing or the door 3 is also solved for cleaning purposes on the "floating" connection ( FIGS. 7 and 8 ).

It is also possible not, as described above, to work with metal balls, but with appropriate plastic glides, but the precision of the metal ball unit is not achieved, if only because sliders wear much faster and thereby "air" (= tolerance extension) arises between glider and leadership.
