Description

The invention relates to a railing system for a shower enclosure with a holding rod, which is suitable for holding a movable shower door and / or for attaching a fixed wall element, and with at least one railing rod, which is attached to this holding rod with one of its ends and whose The end facing away from the support rod is equipped with a device which is suitable for attaching the railing rod to a wall or a side wall or to another railing rod.

Showers, shower enclosures and shower cubicles are known in a wide variety of forms. The term “shower enclosure” used here refers to all of these types of showers.

There is often a shower door in the entrance opening of a shower enclosure, which can close the entrance opening and then release it again. Fixed partitions can also be installed next to this shower door.

There is now often a desire to have one in the interior of a shower, which is shielded from the outside by a shower partition, for example Install a shower seat so that, for example, a person with limited mobility can sit on this shower seat and thus be supported in personal hygiene.

A shower bench, for example, is from the German utility model DE 298 16 224 U1 known. This shower bench is designed to be foldable.

A shower enclosure and a shower seat are also available DE 20 2007 008 505 U1 known. This shower enclosure is equipped with a shower seat that is removable and can be hung on a support rail. The shower seat described there is also foldable and equipped with a support leg for floor support.

Another shower seat is from the German utility model DE 20 2011 106 262 U1 known. This shower seat can be swiveled and is attached to a height-adjustable support. The carrier in turn is attached to a wall or something similar.

More shower seats are out EP 1958557 A2 and EP 1958558 A2 known.

What all of the shower seats mentioned above have in common is that they represent separate devices that are not connected to the shower enclosure or the supporting elements of the shower enclosure.

From the DE 31 04 222 A1 a shower cubicle with a frame-like holder is known, which essentially consists of approximately vertical pipes in the area of the access opening of the shower cubicle and cross rods connected to these pipes. The crossbars are connected to the pipes on the one hand and to the wall on the other. The scaffold-like holder provides support when using the shower cubicle by disabled people.

The US 2014/0124598A1 describes an adjustable device with a length-adjustable telescopic rod to which not only a shelf but also a shower head holder can be attached.

The teaching of the US 2015/0115119A1 is directed to a cantilever beam system that includes a horizontal beam and longitudinally extending upper and lower arm beams that can be attached to a wall. The support rod has an outer tube and an inner tube, which is telescopically accommodated in the outer tube. The support rod contains a tensioning device inside and is adjustable in length.

The practical and aesthetic requirements for shower rooms and shower cubicles have increased significantly in recent times in order to meet increased wellness demands. In addition, such shower rooms and shower cubicles should not only meet increased safety requirements, for example by providing handrails or handles or shower seats, but also offer better comfort by, for example, integrating facilities for shower utensils such as soap dishes, etc.

The one not pre-published EP 18190243.8 describes a shower enclosure with at least one shower door having a flat or curved pane, which is pivotable to at least partially close or reveal an entrance opening and which is supported by a support rod which has one end with a floor fastening which is suitable for a floor , to rest on the edge of a shower tray or the like, and is equipped at the other end with a wall holding device or a ceiling holding device.

This shower partition is characterized in that the holding rod has at least two spaced-apart cross bars, each of which is pivotally mounted on this holding rod by means of an articulation about the longitudinal axis of the holding rod and by means of a suspension on the pane of the shower door at a distance from a side edge of the pane are attached.

According to a preferred embodiment, at least one holding rod is connected to a railing rod extending perpendicularly thereto, the railing rod being connected to the holding rod at one end and having a wall bracket at the other end. A shower seat can be attached to this railing bar.

The revelation content of this EP 18190243.8 is hereby incorporated into the present application by reference thereto.

The object of the present invention is to provide a railing system for a shower enclosure. This railing system should be connected to the shower enclosure and have such mechanical stability that not only light shower accessories but also a shower seat can be attached to it and the safety of the people showering is increased.

This task is solved by a railing system according to the preamble of claim 1, which is characterized in that the railing rod is equipped with a tensioning device inside the railing rod, the tensioning device comprises a spindle, the spindle has an external thread at both ends, whereby an external thread is screwed into a corresponding threaded hole in or on the holding rod and the other external thread is screwed into a thread attached to the railing section facing away from the holding rod, and the tensioning device clamps the railing rod to the holding rod on the railing section of the railing rod facing away from the holding rod.

In the context of the present application, the term “railing rod” refers to a pipe or a rod of any cross-sectional shape and size. It is preferably a tube in the form of a hollow tube or a hollow rod with, in particular, a round or square cross-section. The diameter is preferably 5 to 12 cm and particularly preferably 3 cm.

The railing rod can be designed in one piece. In this case, the term “railing section” refers to an area of the one-piece railing rod, which is preferably a hollow tube. The railing section facing away from the holding rod is in particular the last third or quarter of the length of the railing rod facing away from the holding rod.

The railing rod preferably has a plurality of railing sections (7, 8, 9) which are arranged one behind the other in the axial direction, but are separate. The individual pipe sections are also expediently hollow pipes.

The tensioning device engages the railing rod at a point or area that is as far away as possible from the holding position. The other point of attack is in the handrail or on the handrail.

The clamping device thus comprises a spindle. The clamping device also includes those elements by means of which the spindle is connected to the holding rod or the railing rod.

The spindle has an external thread at both ends, with one external thread being screwed into a corresponding threaded hole in or on the holding rod and the other external thread being screwed into a thread attached to the railing section facing away from the holding rod.

Preferably, a connecting device for fastening the railing section of the railing rod facing the holding rod is arranged on the holding rod. The connecting device has a clamping shell that surrounds the holding rod. The clamping shell is equipped with a connecting pin. The connecting pin is inserted into the interior of the railing section facing the holding rod and has the threaded hole into which the external thread of the spindle is screwed.

The railing bar is preferably equipped with at least one crossbar which is attached to the railing bar and is suitable for attachment to a wall or side wall of the shower enclosure. Furthermore, the crossbar is attached to the railing rod between two railing sections. The railing sections are preferably pipe sections.

A further preferred embodiment is characterized in that the crossbar has a connecting sleeve at its free end, which extends perpendicular to the longitudinal axis of the crossbar, which protrudes beyond the crossbar on both sides, onto which the ends of the railing or pipe sections pointing towards the crossbar are pushed and which has a continuous opening through which the spindle extends, in particular two crossbars being present.

One or more shower accessories such as a soap dish, shelf, mirror, holder for a window squeegee or similar can preferably be attached to the railing rod and also to the holding rod. Preferably, a shower seat is attached to the railing bar, which is also preferably removably hung on the railing bar.

The railing system according to the invention can also include a further 2nd railing rod as well as a further 2nd holding rod. In this case, the shower enclosure has two pivoting shower doors or, instead of the second shower door, a fixed wall element attached to the second holding rod.

In the latter case, the free end of the second railing rod is preferably attached to the first railing rod.

The subject of the invention is therefore also a shower partition with a railing system as described above, with a shower door being pivotably attached to the 1 holding rod. There can also be a second holding rod and a second railing rod.

Detail A of the Fig. 6 .

At the in the Figure 1 In the corner shower with corner entry shown in a perspective view, the shower room is formed, among other things, by an approximately square floor 20 when viewed from above and a side wall 21 and a side wall 22, which form a corner of the shower room with their vertical, mutually pointing and abutting side edges.

The opposite corner is the corner entry. A shower door (not shown) in the form of a glass door is used to open and close the sides opposite the side walls 21 and 22. One of the glass doors is attached to a 1st support rod 4, while the other glass door is attached to the 2nd support rod 5. The attachment is such that the two shower doors or glass doors, not shown, are pivotably attached to the support rods 4 and 5, respectively. Cross bars 6, which have the same axial length and extend perpendicular to the longitudinal axis of the first holding rod 4 or the second holding rod 5, are used for this purpose.

The first holding rod 4 and also the second holding rod 5 are placed on the floor 20 using a floor fastening. At the other end of the two holding rods 4, 5, a wall holding device for fastening the holding rods 4, 5 to the side wall 21 and 22 is arranged. The support rods 4 and 5 each represent a rigid tube which is attached and fastened at its upper and lower ends in the shower niche or in the shower room.

This type of attachment and design of the holding rods 4, 5 and the glass doors as well as their pivotable articulation on the holding rods 4, 5 is in the above-mentioned EP 18190243.8 described in more detail. This disclosure is hereby incorporated by reference.

A first railing rod 2 extends from the approximately vertical first holding rod 4, which runs approximately perpendicular to it and thus horizontally when installed and which is attached at one of its ends to the first holding rod 4 is attached. The other end of the first railing rod 2 is attached to the side wall 22.

The 1st railing rod 2 is in the Figure 2 presented in more detail. The first railing rod 2 is attached to the first holding rod at one end using a clamping shell 10. The other end of the railing rod 2 is on the side wall 22 (compare Figure 1 ) attached.

The 1st railing rod 2 has three railing sections 7, 8 and 9, which are hollow pipe sections.

Two struts 11 are used to fasten the first railing rod 2 to the side wall 21, each of which has a connecting sleeve 12 arranged transversely to the strut 11 at its end facing the first railing rod 2, which is inserted into the opposite end of the associated pipe section 7, 8 or 9 can be plugged in. The outer diameter of the connecting sleeve 12 is such that it is slightly smaller than the inner diameter of the associated pipe section.

The connecting sleeves 12 extend approximately perpendicular to the associated strut 11 and protrude laterally beyond the strut 11.

How to do that in particular Figures 3 to 5 can be seen, a spindle 13 extends through the pipe sections 7, 8, 9 and the connecting sleeves 12, which has an external thread 33 and 32 at both ends.

A clamping shell 10 is used to fasten the pipe section 7 adjacent to the first holding rod 4, which has two half-shells 14, 15, which together form the clamping shell 10, positively surround the first holding rod 4 and, in the assembled state, on the outer surface of the first holding rod 4 issue.

On the half-shell 14 (compare in particular Figure 7 ) a cylindrical connecting pin 16 is attached to the outside, which can be inserted into the end of the pipe section 7 pointing towards the first holding rod 4 with approximately a precise fit.

The connecting pin 16 has a plurality of grooves 37 running in the longitudinal direction on its outer surface, in the corresponding grooves in the longitudinal direction extending ribs 38 come to rest on the inner lateral surface of the pipe section 7, so that the pipe section 7 is non-rotatable with respect to the connecting pin 16 in the assembled state.

Towards the half-shell 14, the connecting pin 16 merges into a flat, cuboid connecting tongue 35. The two largest longitudinal edges of the cuboid extend centrally in the direction of the diameter of the connecting pin 16. The longitudinal axis 36 runs within the connecting tongue 35, so that - to put it simply - the connecting pin 16 is virtually halved.

On the outside of the half-shells 14, 15, a half-jaw 39, 40 is attached and in particular formed, which, when assembled, enclose an approximately cuboid-shaped cavity in which the connecting tongue 35 comes to rest. The half jaws 39, 40 are designed to be congruent in shape and size so that they rest against the connecting tongue 35.

In the half jaw 40 of the half shell 15 there is a through hole 25 arranged perpendicularly (relative to the assembled one) to the longitudinal axis 36, through which a threaded screw 18 provided with a screw head in the form of an Allen screw extends in the assembled state. The threaded screw 18 also extends through a continuous hole 41 in the contracting tongue 35 and engages in a blind hole in the half jaw 39 with an internal thread that corresponds to the thread of the threaded screw 18. By tightening the threaded screw 18, the holding jaws 39, 40 are pressed with the connecting tongue 35. In addition, the two half-shells 14, 15 are pressed together and enclose the first holding rod 4.

Starting from the half jaw 40, an extension 28 extends parallel to the longitudinal axis 27 (refers to the assembled state), which thickens approximately cylindrically at its free end.

The pipe section 7 has at its end pointing towards the first holding rod 4 a recess 17 which extends in the axial direction and is open towards this end, into which the extension 28 can be inserted from the side and which is thus congruent in shape and size to the extension 28 is that the inserted extension 28 cannot be pulled out in the axial direction. On the inside of the half-shell 14, a radial guide nipple 29 is provided for engaging in a bore 41 in the first holding rod 4, which results in a fixation in the longitudinal direction of the clamping shell 10 and thus the first railing rod 2.

An O-ring 58 is used for sealing and is pushed onto the guide nipple 29.

The measures described create a positive and rotationally stable connection between the clamping shell 10 and the first holding rod 4 and the pipe section 7.

Like this in particular Figure 5 shows, there is an axial threaded hole 31 in the connecting pin 16, into which the spindle 13 can be screwed with its external thread 32. The spindle 13 runs in the interior of the pipe sections 7, 8 and 9 and through the connecting sleeves 12 to the pipe section 9.

Like in particular from the Figure 5 As can be seen, ribs 38 which extend in the longitudinal direction are also present in the tube section 9, but which end at a distance from the free end of the tube section 9 on the same axial length. An annular disk 42 is inserted into this pipe section 9 from its free end and rests against the ends of the ribs 38. An axially extending sleeve 43 is inserted into the central bore in the annular disk 42, which has an internal thread 44 in its interior, which can or is screwed onto the external thread 33 of the spindle 13.

At its edge pointing towards the free end of the pipe section 9, the sleeve 43 merges into an annular flange 44 which extends radially outwards and which is or comes into axial contact with the annular disk 42.

The annular flange 42 and thus the sleeve 43 are secured in the pipe section 9 in a rotationally fixed manner. When the pipe section 9 is rotated, the sleeve 43 is screwed onto the thread 33 of the spindle 13. This pipe cut 9 and thus the 1st railing rod 2 are braced with the 1st holding rod 4.

The bracing can also take place without a rotation-proof connection between pipe section 9 and sleeve 43. For example, the bracing can also take place from the side of the connecting pin 16, in which this bracing is carried out before the connecting pin 16 is attached to the first holding rod 4 by means of the clamping shell 10.

Used to attach the first railing rod 2 to the side wall 22 (compare Figures 1 and 5 ) a circular disk 46, which is attached to the side wall 22 with screws or the like and which has an axial pin 47 which projects into an expansion ring 48 arranged inside the pipe section 9 and thereby clamps this pin 47 with the pipe section 9.

Such a construction has more than sufficient mechanical stability to hold a folding shower seat 49 on it, as shown in the Figure 1 is shown. It is sufficient to simply hang such a shower seat 49 on the first railing rod 2. The hanging position of the shower seat 49 can be freely chosen in order to meet the needs of the user. The hanging position is expediently between two struts 11.

The shower seat 49 is detachably attached to the first railing rod 2 with the help of two holding bars 50 using a hook 51 and can be folded about an axis 52 so that it can be moved from the one in the Fig. 1 position shown can be brought into a vertical position. The shower seat 49 is supported on the side wall 21 by means of two support bars 53.

That in the Figure 1 The railing system shown has a second holding rod 5, which is connected to a second railing rod 3. The structural design of the 2nd handrail 5 and the 2nd railing bar 3 corresponds to that of the 1st handrail 4 along with the 1st railing bar 2.

However, the second railing rod 3 is not made up of three pipe sections but only of a one-piece pipe. However, the tension can correspond to that of the 1st railing rod 2. However, such tension is not absolutely necessary. The difference also lies in the attachment of the second railing rod 3 at its end facing away from the second holding rod 5. There the second railing rod is not attached to a side wall but to the first railing rod 2 using a clamp 54.

Shower accessories, for example a soap dish 55 or a shelf 56, can be attached to these railing rods 3, 4 and to the holding rods 4, 5 a holder for a disc puller 57 or similar. In addition, the railing bars can serve as a handrail and are also advantageous because they extend to the handrails and can be grabbed by a person immediately when entering the shower room.

Unless the material is specifically described, as in the case of the glass doors, the elements of the railing system can be made of any suitable material, for example a metal and/or a plastic material.

The handrails and railing rods of the railing system preferably have the same diameter and are made of the same material.
