Description

The invention relates to a shower partition in the form of a folding door, in particular consisting of silicate safety glass, which can be pivotally attached to a wall with the aid of hinges, each consisting of a wall-side and a door-side element.

Shower partitions or shower doors of this type, with which shower niches can be locked to shower cubicles in the simplest technical way, have long been known. A problem often, especially in the case of hardened and therefore no longer workable silicate glass doors, is that deviations from the right angle between the upper edge of the shower base, which is mostly used as an alignment edge for the lower edge of the door, on the one hand, and the wall, on the other hand, can only be compensated for with difficulty, if at all can be. Even if one supports the contact surface of one of the two hinges on the wall so far that the lower edge of the folding door runs parallel to the upper edge of the shower tray with the necessary small distance, a wedge-shaped distance corresponding to the relining remains open between the hinged side edge of the folding door and the wall through which water can escape.

The invention is therefore primarily based on the task of designing the articulation of the folding door in such a way that the respective adaptation to structural conditions is possible without foregoing the shielding function of the folding door.

This object is achieved in that each wall-side hinge element consists of two mutually displaceable parts for changing the distance of the pivot axis from the wall plane, of which the first part receives the pivot pin and the second part has means for stationary attachment; that the second parts of the wall-side hinge elements are attached to a common wall strip; and that the first hinge parts have receiving means for a cover profile overlapping the wall strip.

With the help of the adjustable hinges, the lower edge of the folding door can be easily aligned with the respective cover component. With this orientation, the cover profile is carried along by the first hinge parts, so that its relative position relative to the folding door remains independent of the setting of the hinges. A closed in the _K lapptürstellung narrow, the passage of splashing preventive gap between the folding door and the cover profile is thus obtained. The overlap of the cover profile with the wall hinge common to the two hinges, which does not change their relative position to the second parts of the hinge, ensures that even when the cover profile is moved relative to the wall rail during the hinge adjustment, there is no gap between the wall and the hinges that allows splashing water.

Although - as I said - the distance between the hinged side edge of the folding door and the cover profile is very small can be held and does not change when the hinges are adjusted, an elastic lip profile is preferably additionally attached to the cover profile along its other longitudinal edge with its free longitudinal edge on the folding door.

In the closed state, the free edge of the folding door can engage in a fold provided by the customer or be bluntly opposed to a counter wall. If, however, a special stop bar is provided for the free edge of the folding door, then in a further development of the invention, which is not limited to this, it is part of a stop profile corresponding to the cover profile, which overlaps a wall bar and is adjustably attachable to it. In this case, the stop profile preferably has a section which engages in the wall strip and in which expansion bodies are guided which can be widened from the outside in positive engagement with toothed surfaces of the wall strip. Several such expansion bodies can be provided over the height of the wall strip of the stop profile, the accessibility of which from the outside is facilitated by releasable clamping of the stop strip in the stop profile.

Difficulties arise with shower enclosures _; Folding doors whenever they have to be opened to the outside - i.e. away from the shower - because then water running down the door drips onto the floor in the room outside the shower. On the other hand, a shower cubicle, which is closed off by an inward opening door, is difficult to enter and leave. In order to counter the above-mentioned difficulty with a folding door that opens outwards, according to another development of the invention, which is not is limited to the design of the hinged door linkage described above, it is provided that a water drainage channel is fastened on the inside to the lower edge of the hinged door, which is closed at the free edge of the hinged door and is open to the shower at the hinged edge. Water running off on the inside of the folding door does not drip, but gets into the water drainage channel and is discharged into the shower near the swivel axis.

Preferably, the water drainage channel is connected to at least one downward-extending, elastic splash-water deflection strip, which allows the lower edge of the hinged door to be spaced from the reference component (for example, an upper edge of the shower tray) for safe door function, without splash water being able to escape to the outside. This or one of the splash-water deflecting strips advantageously interacts with a rail which can be fastened on an edge of the shower base or the like and which bears sealingly on the shower base or the like with an integrally formed soft lip. The - essentially rigid - rail, which can be attached to the reference component, for example by gluing, offers a precise reference edge to the lower edge of the folding door, the soft lip covering and protecting the fastening of the rail to the underlying component.

1 consists of the folding door 1, the upper and lower hinges, of which only the parts 16 and 24 or 24a are visible, the hinge-side wall bar 4 with the cover profile 5 and the opposite wall bar 6 with the stop profile 7 and the stop bar 8. More details on the formation of the hinges and the various bars and profiles can be found in FIGS. 2 to 4.

The second part 11 of the upper wall-side hinge element 2 is fastened to the wall bar 4, which can be fastened to a wall for example by screws (fastening holes 10), using screws 12. It has an angular shape in the vertical section of FIG. 2 and is provided on its upward-facing surface 13 with a serration parallel to the wall plane 14 (= wall-side surface of the wall rail 4). A corresponding serration 15 is provided on the associated lower surface of the first part 16 of the hinge element 2, which extends like a cantilever from the wall plane 14 and is fastened to the second part 11 of the hinge element with the aid of a screw 17. The elongated hole 18 provided for the screw 17 in the first part 16 allows the parts 11, 16 to be adjusted relative to one another after the screw has been loosened, so that the distance between the pivot axis 19 and the wall plane 14 can be changed. A pivot pin 20 which is concentric with the pivot axis 19 is fastened by means of its screw section 21 in the first part 16 of the hinge element 2 and engages at 22 in a bearing part 24 fastened to the door leaf 23.

A corresponding to the cross section of the cover profile 5 (Fig. 3 and 4) shaped groove 25 in the lower surface of the first part 16 of the hinge element 2 forms a means for receiving and holding the cover profile 5, so that the cover profile with a relative adjustment of the hinge parts 11, 16 5 is taken with the second hinge part 16 and its position relative to the pivot axis 19 and thus to the articulated edge 26 of the folding door 1 does not change.

The design of the lower wall-side hinge element 3 is largely corresponding, and similar parts are designated by the same reference numerals. The only difference is essentially the screw 17a, which is inserted from above through the second part 11 and the elongated hole 18 of the first part 16 and is screwed to a nut 27. Furthermore, the hinge pin 20a is a simple pin which is pressed into the first part 16 of the hinge element 3 and is inserted into the bearing part 24a on the door leaf 23 of the folding door 1. But here, too, a groove 25 in the corresponding - here, of course, upward - surface of the first hinge part 16 for receiving and holding the cover profile 5, so that it maintains its overall position relative to the folding door 1 when the hinge elements 2, 3 through Relative adjustment of their parts 11, 16 to be adapted to the local installation conditions.

3 and 4 make it clear how the cover profile 5 overlaps the legs 28 of the wall strip 4, so that different adjustment of the hinge elements 2, 3 results in a shadow groove of different width between the wall and the edges of the cover profile 5 facing it, but not a gap permitting splash water. The important distance between the cover profile 5 and the articulated edge 26 of the folding door 1 remains unaffected by a hinge adjustment.

An elastic lip profile 29 is fastened on the inside along its longitudinal edge 30 to the cover profile 5, namely inserted into a groove 31. With its free longitudinal edge 32, it bears sealingly on the door leaf 23 of the folding door 1, but due to its elasticity and slight pretension easily follows its pivoting movements.

Fig. 3 also illustrates how the stop bar 8 is part of the stop profile 7, namely inserted into this clamping. An U-shaped section 40 of the stop profile 7 integrally formed on the inside engages between lateral jaws 41 of the wall strip 6, which have longitudinal grooves 42. Distributed over the height of the stop profile 7 in the U-shaped extension 40 (short) expansion body 43, which can be widened with the aid of the screw connection 44 and the wedge 45 in such a way that lateral extensions 46 are pressed into the longitudinal grooves 42 and form-fitting Establish connection between the stop profile 7 and the wall bar 6, in such a way that the stop bar 8 has the same relative position to the door leaf 23 of the folding door 1 over its entire height.

5 illustrates the further development described above in the area of the lower edge 50 of the folding door 23. A section 52, 53 of a plastic profile 51 encompasses the lower edge 50 and is glued to the door leaf 23. A further section 54 of the profile 51 forms a water drainage channel 55, which - in a manner not shown - is closed at its end adjacent to the free edge 33 of the folding door 1, while - also not shown - that adjacent to the hinged edge 26 of the folding door 1 Drained towards the shower interior. On the underside, elastic splash-proof strips 56, 57 extending downward are formed on the profile 51. These interact with a rail 58, the relatively rigid section 59 of which is attached to a base (for example the upper edge of a shower tray) with the aid of an adhesive strip 60. can be attached while a molded soft lip 61 provides the seal to the interior of the shower (on the right in FIG. 5) and at the same time covers the permanently elastic putty which is arranged in the cavity 62 between the section 59 and the lip 61 of the rail 58 can.

To the interior of the shower base, the profile 51 also continues in a lip 62, which prevents the impingement of splash water and large amounts of splash water on the edge seal formed by the deflecting strips 56, 57 with the rail 58 from the outset. The cross-hatching of certain sections of the profile 51 indicates that these are sections made of softer plastic than the other profile sections.

The modification of the hinge design shown in FIGS. 6-9 relates to the lower wall-side hinge element 3, and specifically to the interaction of its first part 16 with the pivot pin 20a and the bearing part 24a fastened to the door leaf 23 (FIG. 2). The modified design of the lower hinge element 3 provides that the door leaf 23 (which is not shown in Figures 6-9) is raised when the door is opened, remains in the open state (approximately 90 ° opening angle) and when the door is closed during the last part of the closing path (approximately from a remaining opening angle of 45 ° to 30 °) automatically completes the closing process and exerts a closing force on the stop bar 8. In order not to hinder the lifting of the door leaf 23, the upper hinge element 2 with its first part 16 must be at a distance from the door leaf 23; this is already provided in the embodiment shown in FIG. 2, so that when the door leaf 23 is lifted, the pivot pin 20 penetrates deeper into the bearing part 24.

Hinge elements which raise the door leaf when opening and release a closing force when closing are known per se. However, their constructive training has proven disadvantageous for a number of reasons. For example, the distribution of the closing force over the opening angle is unfavorable for optimal function (especially in the case of a shower partition), and the known hinge lifting devices also wear out too quickly. The hinge design described below avoids these disadvantages.

The pivot pin 20a is fastened in part 16 of the lower hinge element 3 (FIG. 2). In the bearing part 24a, which in turn is attached to the door leaf 23 (not shown), the pivot pin 20a is axial, i.e. vertically movable. The surface section 70 of the upper side of the hinge part 16 facing the bearing part 24a is beveled, as can be seen in particular from FIGS. 6-8.

A disk 71 is arranged between the surface section 70 and the underside of the bearing part 24a facing it. This engages around the pivot pin 20a with an essentially U-shaped cutout 72, the edge of the cutout 72 having the configuration which can best be seen in FIG. 6 for adaptation. Furthermore, in extension of the central axis of the U-shaped Cutout 72, a spherical socket 73 formed on the upper side in the disk 71, into which a spherical cap 74 engages, which forms the end of a pin 75 which projects vertically downward from the bearing part 24a and is fastened in the latter. Compared to the pivot axis determined by the pivot pin 20a, the central axis of the pin 75 is offset eccentrically by the dimension x (towards the free vertical edge 33 of the door leaf 23).

The weight of the door leaf 23 is supported by the bearing part 24a, the pin 75 and the washer 71 on the surface section 70 of the hinge part 16. In the opening state shown in FIGS. 6 and 7 (opening angle 90 °), the force resulting from the weight does not produce any torque about the pivot axis of the hinge pin 20a. Only the reduction in the opening angle when the door closes gives rise to such a torque, because then the horizontal force component generated by the slope of the surface section 70 no longer passes through the pivot axis, but passes it; the vertical distance of this component from the swivel axis represents the lever arm of the torque. Because this lever arm - starting from zero at an opening angle of 90 ° - is initially very small, only a small amount of torque is initially created. This increases after a sine function with a smaller opening angle and a correspondingly larger lever arm, so that when a remaining opening angle of approximately 45 to 30 ° is reached, the torque is sufficient to carry out the remaining closing automatically and the door leaf 23 to the stop bar 8 to press.

During this swiveling process, the spherical cap 74 of the pin 75 slides in the ball socket 73 of the disk 71, and its cutout 72 ensures, on the one hand, the general arrangement of the disk 71 on the surface section 70 and, on the other hand, allows the disk 71 to move relative to the swivel pin for geometric reasons 20a. Neither the movement of the spherical cap 74 in the ball socket 73 nor that of the disk 71 on the inclined surface section 70 is susceptible to wear, and the increase in the closing force after closing the door when the door is closed ensures that the shower partition is handled comfortably.

FIGS. 8 and 9 illustrate the relative position of the washer 71, which differs considerably from the open state, with respect to the inclined surface section 70 and the hinge pin 20a. In particular, FIG. 8 shows the expediency of the edge contour of the U-shaped cutout 72 in the disk 71.
