Description

The present invention relates to a sliding door, in particular for shower enclosures, with a door segment, at least one upper side, an upper running bar assignable, rotatably mounted on a receiving unit roller, and a lower side of a lower running bar assignable rotatably mounted on a receiving unit role, wherein the receiving units with the Door segment are connectable. Such sliding doors for shower enclosures are known. They have at the top of several roles and in the lower area at least one, preferably also several roles, by means of which they are slidable along bars.

A disadvantage of the known sliding doors that the installation and removal is relatively complex and therefore time consuming and costly.

Such a sliding door with a shower door guide is in DE 103 36 026 A1 disclosed. On the sliding door, a lower roller is mounted resiliently, so that the roller can be brought out by applying a transverse force from the guide rail. In DE 32 09 768 A1 discloses a sliding door, wherein the sliding door is mounted vertically displaceable with respect to the running in a head rail roller.

Object of the present invention is therefore to provide a sliding door in particular for shower enclosures, which can be easily installed and removed and which is quickly exactly adjusted relative to the running rails.

The invention solves the problem with a sliding door of the type mentioned in that the upper and lower rollers are adjustable in height to provide a largely backlash-free lateral mobility of the door segment.

Advantages of the invention are that a quick installation and removal is made possible by the adjustable top and bottom rollers, because when Höhenverstellen at least one role, the complete sliding door by means of the rollers can positively engage with the rails, so that the sliding door the Installation securely fixed between the rails but can be moved. By simply adjusting at least one roller in height, ie in the mounted state in the vertical direction perpendicular to the longitudinal extent of one of the rails, the roller and thus the door segment can be pivoted, for example, from the running bar and then completely lifted by the other running track. In this way, a quick assembly and disassembly is possible.

Another advantage of the invention results from the play-free mobility of the door segment. The regularly occurring in conventional shower enclosures disadvantage that the door segments jam when opening or closing due to a slight tilt against the running rails and make further movement possible only with increased effort or must be solved by a slight shaking, is reduced by the sliding door according to the invention.

Various materials have proven themselves in use. Thus, it has proven to be advantageous to form the door segment with a glass or plastic disc, which is optionally covered by a frame made of metal or plastic. The rollers, runners and receiving units are suitably made of a material that the weight of the door segments and possibly occurring. briefly acting forces can be absorbed. With regard to the rollers and their associated runners, the wear resistance of the material must be taken into account. Suitable materials for the aforementioned parts metals such as aluminum or hard plastics have been found. Deviating from this, however, other materials can also be used, for example from renewable raw materials such as wood.

In a further embodiment of the present invention, at least one elastic element of the receiving unit is associated and adapted to eliminate as far as possible the movement play of the door segment relative to the running rails by generating a biasing force. The elastic element is in this case advantageously designed so that it deforms in a vertical deflection of the door segment or in a direction perpendicular to the direction of the running rails, wherein the elastic element is arranged between the roller and the receiving unit, that the position of the roller changes relative to the receiving unit due to the deformation of the elastic element. This happens in particular when a force is exerted in the vertical direction or in the direction perpendicular to the running rails on the door segment. After elimination of this deflection force causes by the Deformation of the elastic member resulting restoring force the return of the roller to its original position relative to the receiving unit.

In a further embodiment of the present invention, the elastic element is designed as a helical spring. The use of coil springs as elastic elements has been found to be advantageous because coil springs are inexpensive to produce, have a linear spring core line and can be interpreted relatively simple in terms of the weight of the door segment and the expected forces acting.

According to a further advantageous embodiment of the present invention, the rollers are infinitely height-adjustable by means of a substantially cylindrical adjusting screw relative to the door segment. By using the adjusting screw, the position of a roll to its associated recording unit can be set exactly and with good repeatability. This results in an easy to perform and exactly to be made adjustment of the position of the door segment relative to the running rails.

According to a further embodiment of the sliding door according to the invention, the cross-sectional profile of the rollers on a running surface on a circumferential, preferably bulbous recess which is engageable with a correspondingly shaped, preferably trapezoidal cross-sectional profile in the running bar substantially form-fitting manner. The development of such a profiled running surface of the rollers and the associated running bar has the advantage that the rollers are better guided in the running direction on the running bar, which results in a more uniform course of movement of the door segment. Another advantage is seen in addition to this leadership function in that the V-shaped recess assumes a centering function. The sliding door is thus always in a defined and constant level as soon as the rollers of the receiving units with their associated rail are engaged. Although it has been found to be advantageous that a V-shaped recess or groove on the running surface of the roller with a correspondingly formed projection in the tread of the mileage can be brought, deviating cross-sectional geometries of the roller or the running bar are also conceivable. For example, the groove or the projection in the two elements could also be semicircular.

According to a further embodiment of the present invention, the rollers are movable by means of a button counter to the direction of action of the biasing force to the To remove the intervention in the running bar. The button can in this case be designed so that the elastic elements which apply the biasing force transmitted to the rails by means of the rollers are further deformed by actuation of the button, whereby the position of the rollers is further changed relative to the receiving unit, and thus the rollers after sufficient deflection of the button, release it from the track. If the runners and rollers are formed with a corresponding "uneven" cross-sectional profile, can be solved in this way, the existing between the two elements engagement.

According to a further embodiment of the sliding door according to the invention, the button can be locked in an end position. By the lockability of the button in an end position, in particular in the end position in which the elastic elements are deformed so far that the engagement of the rollers is canceled in the running bar, it is ensured that the door are partially or completely removed from the shower enclosure can, without the individual roles hinder disassembly or assembly of the door segment on the shower enclosure. In particular, after the installation of the sliding door would have the advantage that by simply releasing the locking of the button, the rollers are brought by the restoring force of the elastic elements with the running bar in engagement and set the position of the door immediately unique.

According to a further embodiment of the present invention, the door segment is pivotable about a pivot axis parallel to the upper and / or lower running bar with the engagement of the rollers. The ability to swing the door segment out of the mounting position greatly simplifies the cleaning of the door segment as well as the shower enclosure as a whole. The release of the engagement between the lower rollers and the lower track bar allows the door segment to pivot upwardly, while disengaging the engagement between the upper roller and the upper track bar allows pivoting down. Another embodiment of the sliding door could be designed so that the door segment is pivotable about a vertical axis. This succeeds in particular when not both upper or both lower receiving units are released from the engagement, but in each case only one upper roller and a lower roller assigned to it, while the respective other rollers remain engaged. The pivotal movement of the sliding door in such a case is similar to the movement of a conventional door.

According to a further embodiment of the sliding door according to the invention, the receiving unit is formed substantially symmetrically to a horizontal center plane. The horizontal center plane extends through an axis of rotation of the roller.

This horizontal mirror-symmetrical design of the receiving unit makes it possible to use the same receiving unit as both upper and lower receiving unit and to attach to the door segment. This results in saving opportunities for the production of the receiving unit and the sliding door as a whole.

According to a further embodiment of the sliding door according to the invention, the rollers are designed as double rollers. Under double role here the arrangement of two roles in the direction of succession understood. It has been shown that the arrangement of two rollers on a receiving unit in the described orientation has an advantageous effect on the running behavior of the sliding door.

According to another embodiment of the present invention, a replaceable bumper is disposed on a side surface of the receiving unit. The bumper serves to prevent damage to the receiving unit by too energetic opening or closing the sliding door, especially when the sliding door in such an opening or closing operation abuts against another door segment or a frame part of the shower enclosure or the like. Due to the interchangeability of the bumper this can be easily changed when signs of wear and tear occur.

According to a further embodiment of the present invention, the sliding door is formed substantially symmetrically with respect to a central axis, so that the shower enclosure can be attached to the running rails in any vertical orientation. This symmetrical shape of the design of the sliding door is used to facilitate assembly. With a symmetrical design of the sliding door, it is no longer necessary to define an upper and a lower side of the door.

In a further embodiment of the sliding door according to the invention two upper receiving units and two lower receiving units for guiding the movement of the sliding door are arranged on the door segment, wherein the receiving units are each independently height adjustable. By attaching two upper or lower receiving units, it is possible to tilt the entire door segment and set in this way the angle between the vertical boundary of the door segment on the one hand and the shower wall and / or other door segments on the other. As a result, a nearly optimal closing behavior of the door segments can be achieved because angle errors can be compensated.

In a further embodiment of the sliding door according to the invention, a securing element can be fastened to an end section of the upper and / or lower running strip. The securing element allows additional securing of the receiving unit including roll or rollers against unintentional removal. The attachment of the securing element can be achieved by means of known fastening means.

According to a further embodiment of the present invention, the securing element can be locked on its associated running bar. Means for locking are inexpensive to produce and reduce assembly costs compared to alternative fasteners such as screw. The latching is advantageously designed as a clamping section with a barb on the securing element.

The invention solves the problem initially posed by a shower enclosure with a sliding door according to one of claims 1 to 13.

In FIG. 1 a sliding door 1 according to the present invention is shown in the mounted position in a shower separating device. The sliding door 1 has a door segment 3 which is displaceable along an upper running bar 5 and a lower running bar 7 parallel to the upper running bar 5. Upper receiving units 9 connect the door segment 3 in an upper portion 13 of the sliding door 1 with an upper bar 5. Lower receiving units 11 connect the door segment 3 of the sliding door 1 in a lower portion 15 with a lower running bar 7. The illustrated sliding door is to a horizontal axis 14 formed symmetrically.

In FIG. 2 the upper portion 13 and the lower portion 15 of the sliding door 1 according to the invention are shown in more detail. For reasons of clarity, the door segment 3 was shown only shortened. The upper receiving units 9 partially have a button 17, which can be actuated for unlocking or for releasing the connection between the sliding door 1 and the running bar 5. The lower receiving units 11 also partially have the button 17. The recording units 9 and 11 shown in the illustration on the right have no button. By pressing the two buttons 17 of the left receiving units 9 and 11, the compounds of these receiving units are solved with the running rails 5 and 7, so that a lateral pivoting of the entire sliding door 1 results, while the right receiving units 9 and 11 with the runners 5 and 7 stay in contact.

FIG. 3 shows the sliding door 1 according to the invention in a view from above. In this illustration, it can be seen that the receiving units 9 have fastening screws 6 in an illustrated upper section, which extend through the receiving units 9 and engage the door segment 3. Furthermore, in each case a pressure plate 21 and an adjusting screw 23 is arranged on the receiving units 9. The function of these elements will be explained later on the basis of FIGS. 5 to 7 explained in more detail.

A further preferred embodiment of a receiving unit 9 is shown in FIG FIG. 4 shown. According to this embodiment, the receiving unit 9 has a through hole 25, which is designed to receive the fastening screw 6. Furthermore, the receiving unit 9 has a recess 26, within which a roller mount 31 is partially arranged. The roller mount 31 is movable along an axis 30. The movement downwards along the axis 30 is limited by the receiving unit 9 itself, while the mobility upwards out of the recess 26 by a pressure plate 31 which is connected by means of an adjusting screw 23 with the receiving unit 9. The height of the mobility of the roller holder 31 is adjustable by the adjusting screw 23. The roller holder 31 has two, in cross section in FIG. 5 illustrated pin 37, which are designed to receive rollers 19. Furthermore, the in FIG. 4 shown receiving unit 9 recesses 29. The recesses 29 serve to save weight.

FIG. 5 shows a cross section through a sliding door according to the invention. A door segment 3 is connected in an upper portion 13 of the device 1 according to the invention with an upper receiving unit 9. In a lower section 15, the door segment 3 is connected to a lower receiving unit 111. In the receiving unit 9, a roller holder 31 is arranged, which is movable up and down. As already explained above, the adjustability of the height is limited by the recording on the one hand and a pressure plate 21 on the other. Between the roller holder 31 and the receiving unit 9, a coil spring 35 is arranged. The coil spring 35 is adapted to generate a biasing force when the adjusting screw 23 is turned down in the lock shown in the receiving unit 9. The same applies to the coil spring 35 in the receiving unit 11, but due to the orientation of the receiving unit 11 in the reverse direction. Increasing the biasing force causes the adjusting screw 23 to move upward in the direction shown. In the embodiment shown here, a roller 19 is pressed with integrated ball bearing 33 on the pin 37 of the roller holder 31. The roller 19 has a V-shaped recess 34 on its running surface. This V-shaped recess 34 is in positive contact with a correspondingly formed profile 36, which is formed on the running surface of the running bar 5 and 7 respectively. The upper receiving unit 9 and the lower receiving unit 11 each have a button 39, whose operation will be described below.

In the mounted position, the dead weight of the door segment 23 and the receiving unit 9 compress the upper coil spring 35, and the door segment 3 moves slightly downwards. As a result of the downward movement, the coil spring 35 of the lower receiving unit 11 is relieved. Unlike the door segment 3 and the lower receiving unit 11, the lower roller receiver 31 does not move downwards, but remains in the same position. In this way, the contact of the roller 19 of the lower receiving unit 11 with the lower running bar 7 is still guaranteed. Now, if a disassembly or pivoting of the sliding door 1 is necessary, the button 39 of the lower receiving unit 11 is pressed down. By this pressing counter to the direction of action of the coil spring 35 of the lower receiving unit 11, the roller holder 31, together with the attached to her and rotatably mounted roller 19 is moved downward. The engagement between the roller 19 and the running bar 7 is released. This operating state is in FIG. 6 shown.

After the button 39 has been moved to its end position, it is possible to fix it by means of a (not shown) locking in this position, so that the roller 19 together with the roller seat 31 of the lower receiving unit 11 is not automatically in engagement with the running bar. 7 can get. It is now easily possible from the in FIG. 6 shown operating state in the in FIG. 7 shown operating state in which the door segment 3 together with the receiving unit 11 is pivoted away to one side.

In FIG. 8 a fuse element 41 is shown, which serves to secure the (not shown) receiving unit 9 in the running bar 5 against unintentional removal. The securing element 41 is attached to an end portion 43 of the running bar 5. The securing element 41 is embodied such that two webs 47, 49 have to be elastically deformed for attaching the securing element 41. By elastic deformation restoring forces are applied, which act counter to the deformation direction and conditional upon the attachment of the securing element 41 on the running bar 5 a clamping action. In the embodiment shown, the securing element furthermore has a barb 45 on one of the clamping sections, which barb engages in a correspondingly formed recess 46 in the end section 43.
