Abstract

At least one end of the holder bar (1) has an axially protruding coupling rod (4) of smaller cross-section and movable and fixable axially in relation to the holder bar. The coupling rod free end protruding beyond the holder bar has couplings, in the form of an external thread, or a smooth plug or clamping part, joining it to an adjacent bar and/or support (3) or wall attachment. A threaded sleeve (5) inside the holder bar has an inner opening matching the coupling rod outer section. A clamping, grub screw (6) fixes the holder bar to the coupling rod which goes through a hole (9) in a radially inner part of a cap (8) covering the holder bar end.

Description

The invention relates to a handrail to be arranged in a substantially horizontal plane for holding and / or stiffening partition walls for shower cubicles, the handrail having fastening elements with which fastening directly to the partition wall or its frame and / or indirectly to a support profile supporting the partition wall or a support is possible.

Handrails of this type are known and are generally provided in the upper edge region of partition walls for showers, where they can also carry the mounting rail for a sliding door for opening and closing a shower cubicle in a large number of cases. However, with these previously known handrails, it is difficult to compensate for dimensional deviations or tolerances, be it in relation to a solid building wall, be it at the connection points with vertical supports or support profiles or, finally, in the area of the connection of two horizontal handrails, for example on one Corner connection at an angle to each other and corresponding cabin walls should hold. In particular, a coupling in the corner area between two holding rods at an angle to one another has so far not allowed any adaptations to different dimensional deviations or to relatively large tolerances customary in construction.

The invention is therefore based on the object to provide a support rod of the type mentioned, which can be adapted to different dimensions or to dimensional deviations and tolerances in a simple manner without impairing its holding function.

This object is achieved in that the holding rod has on at least one of its end faces an axially projecting coupling rod, the cross section of which is smaller than that of the holding rod, and that this coupling rod is adjustable and fixable relative to the holding rod in the axial direction. With the help of this coupling rod, different dimensional deviations in the front area of the holding rod can be compensated for by adjusting the coupling rod accordingly.

It is useful if the coupling rod protruding from the holding rod has coupling means at its free projecting end for connection to a neighboring rod and / or to a support profile or a wall connection. This coupling means can be an external thread or a particularly smooth plug-in and clamping area. The support rod can thus be fixed with the help of the displaceable coupling rod by the relative adjustment of this coupling rod and its fastening on the one hand outside the holding rod and on the other hand in a desired position relative to the holding rod. Any existing dimensional deviations can therefore be bridged in a simple manner.

It is particularly advantageous if the coupling rod is displaceable and fixable in the longitudinal direction of the holding rod. Adaptation to different dimensions can be carried out correspondingly simply.

To bridge the cross-sectional or diameter differences between the holding rod and coupling rod, a sleeve can be molded or inserted in the inside of the holding rod, the inner opening of which approximately corresponds to the outer cross section of the coupling rod.

The sleeve can be a threaded sleeve, against which the coupling rod can be axially adjustable and fixed by screwing. In this case, for the axial adjustment, a relative rotation is to be carried out at the same time either by turning the coupling rod or by turning the holding rod.

However, the sleeve can also be a sliding sleeve, against which the coupling rod can be fixed in particular by means of clamping, for example with at least one clamping screw. This represents a particularly simple arrangement in which the mutual positioning of the holding rod and coupling rod is particularly simple when the clamping screw is loosened. This also applies in the event that the coupling rod already engages a counterpart with its coupling means. When the mutual positioning is finished, all that is required is to tighten the clamping screw.

The clamping screw or clamping screws for fixing the coupling rod to the holding rod can be one or more grub screws which engage in the holding rod, in particular vertically, from above in the use position. In this way, these clamping screws can be used especially in the upper area Shower cabin arranged handrail can be arranged practically invisible.

A further embodiment of the invention can consist in the coupling rod being angled and / or curved in its area located outside the holding rod. The curvature or bend can form an obtuse or right angle. Thus, partition walls for shower cubicles which are at an obtuse angle or at a right angle to one another can be held against one another, with dimensional deviations occurring on the mutually facing edges being easily compensated for by the corresponding coupling rod. Advantageously, a coupling rod can connect two support rods and engage with their two ends in the end faces of these two support rods. The support rods can have any cross-section, but are preferably circular, while the coupling rod also preferably has a circular cross-section.

On the end face of the holding rod, a cover cap can preferably be detachably arranged, which bridges the cross-sectional or diameter difference between the holding rod and coupling rod and shields the end face of the holding rod, in particular, against splash water. At the same time, this results in a more pleasing appearance than if the coupling rod protrudes directly from the holding rod.

The radially inner region of the cover cap, which has a perforation for the passage of the coupling rod, can be clamped or sealed against the coupling rod under prestress. Above all with a clamping area of this cover cap sealingly around, there is a good sealing of the front exit of the coupling rod from the holding rod.

It should be mentioned at this point that a significant additional advantage of the handrail with coupling rod is that the coupling rod is interchangeable, so any coupling rods of different shape and curvature or angle can be attached to a handrail.

It is possible that the coupling rod, in particular for coupling several cabins or for fixing branches or crossings, can have several legs, for example can have a T-shape or a cross-shape, each having a rod of the T-shaped or cruciform or possibly star-shaped coupling part fits in each case in the end face of a support rod or in the mating coupling of a support profile.

Overall, a combination of one or more of the features and measures described above results in a support rod, which can be adapted in a variety of forms on the one hand by its coupling rod on the other hand but also by its interchangeability to different requirements and dimensions in a simple manner. Elaborate adjustment devices or the waiver of an adaptation to dimensional deviations are avoided without a considerable design and manufacturing effort being required.

Different uses of handrails on different floor plans of shower cubicles or the like with correspondingly different angular positions to one another.

A holding rod, denoted by 1 in each of the exemplary embodiments, even with a different structural design, serves to hold and stiffen partition walls 2 for shower cubicles, examples of which are shown more or less clearly in FIGS. 1, 3, 9, 11 and 17 to 24. The support rod 1 has in each case still to be described fastening elements with which fastening directly to the partition wall 2 or its frame or indirectly to a support profile supporting the partition wall 2 or a support 3 is possible.

As such a fastening element, the holding rods 1 shown in the various exemplary embodiments each have an axially projecting coupling rod 4 on at least one of their end faces, the cross-section of which is smaller than that of the holding rod 1 and which can be adjusted and fixed in the axial direction relative to the holding rod 1. Different dimensions or dimensional deviations and tolerances can thus be easily compensated for and compensated for by this relative adjustability between coupling rod 4 and holding rod 1. This is not only advantageous in the case of a wall connection, but above all also at the transition from one to a neighboring partition 2 and above all when these partitions 2 according to FIGS. 1, 3, 11 or other examples, for example also FIG. 18, stand at different angles to each other. In the case of partition walls of this type which are at an angle to one another, the compensation of dimensional deviations has hitherto been difficult, but is now possible without problems due to the axial adjustability of the coupling rods 4.

The axial adjustability of the coupling rod 4 relative to the holding rod 1 can be realized in different ways:

According to Fig. 2, 4, 5, 7, 10, 12 and 13 to 16, ie the majority of cases, the coupling rod 4 can in the longitudinal direction Support rod 1 can be moved and fixed, wherein a sleeve 5 can be formed (Fig.12 and 14) or inserted in the interior of the support rod 1, the inner opening of which corresponds approximately to the outer cross section of the coupling rod 4 and enables a sliding fit. In these cases, the sleeve 5 is thus a sliding sleeve, against which the coupling rod 4 can be fixed by means of clamping, in the exemplary embodiments mentioned by means of clamping screws 6.

In the exemplary embodiment according to FIG. 8, the sleeve 5 is a threaded sleeve, against which the coupling rod 2 can be axially adjusted and fixed by screwing with an external thread located on it. The setting is made either by the thread itself or by locking with the coupling area or a lock nut not shown in the exemplary embodiment.

In an expedient and advantageous manner, the coupling rod 4 protruding from the holding rod 1 has, in all exemplary embodiments, at its free projecting end a coupling means which, depending on the exemplary embodiment, is designed differently for connection to an aligned or angled neighboring holding rod or with a supporting profile 3 or with a wall connection 3a. This coupling means according to FIGS. 2, 5, 7, 8 and 10 can be an external thread or, according to the other exemplary embodiments, a particularly smooth plug-in and clamping area, on which a corresponding clamping screw 7 can engage.

The clamping screws 6 and 7 for fixing the coupling rod 4 to the support rod 1 or another counterpart are expediently grub screws according to Figures 2, 5, 7, 10 and 12 to 16, which engage vertically from above in the support rods 1 in the use position so that they are arranged above the upper edges of the cabin walls 2 are practically invisible. Nevertheless, the support rods 1 with their coupling rods 4 can be exchanged or easily removed.

To adapt to different angular positions, for example of holding rods 1 relative to one another, as is indicated in FIG. 11, the coupling rods 4 can be curved and / or angled in their area located outside the holding rod 1. Examples of this can be seen in FIGS. 10 and 12 and also in FIG. 6, and applications of this principle in FIGS. 18, 21, 22 and 24. The curvature or angling can be an obtuse or a right angle (FIG .6, 21 and 22) form, in order to be able to set shower partition walls 2 at corresponding angles to one another with the aid of the support rods 1 and these correspondingly curved or angled coupling rods 4.

The support rod 1 can have any cross section, as can be seen above all from FIGS. 13 to 16. A circular cross section is preferred. The coupling rod 4 also expediently has a circular cross section, but could also have cross-sectional shapes that deviate therefrom, for example at least in some areas have flats or polygonal contours, in order to be able to screw the coupling rod 4 appropriately with the aid of a thread belonging to it. For example, in the case of an arrangement according to FIG. 8, a partial polygon in the course of the exposed area of the coupling rod 4 would be advantageous in order to be able to screw the coupling rod 4, which is threaded at both ends, accordingly using a corresponding tool.

A right-angled arrangement of coupling rods 4 can also be achieved in that two coupling rods 4 correspondingly at an angle to one another, starting from corresponding support rods 1 at a right angle to one another on a common one Hit support 3 and couple it in the holes provided there (see Fig. 4).

5, 7, 12 and 2, a cover cap 8 can in particular be detachably arranged on the end face of the holding rod 1, which bridges the cross-sectional or diameter difference between the holding rod 1 and the coupling rod 4 and also shields the end face of the holding rod 1 against splash water, for example . The radially inner region of this cover cap 8 has a perforation 9, the edges of which can rest against the coupling rod 4 in the manner of a sealing lip.

While it is shown in FIGS. 17 to 24 that a wide variety of floor plans of shower cubicles are possible, in which two corresponding support rods 1 are arranged above the cubicle walls, which connect coupling rods 4 that take account of the angular position of the cubicle walls 2 while compensating for dimensional tolerances, FIG. 25 the possibility that the coupling rod 4 for coupling several cabins or for fixing branches or crossings could have several legs, for example a T-shape or a cross-shape. In each case one rod of such a T-shaped or cross-shaped coupling part can then be inserted into the end face of a holding rod 1 or into a mating coupling of a support profile or a support 3 and anchored there.

In all of these cases, it can be clearly seen that dimensional deviations, particularly in the longitudinal direction of the support rods 1, can be easily and easily compensated for by a corresponding displaceability and adjustability of the coupling rods 4. Such deviations in size can be easily absorbed and shower cubicles can be created in which there are no unsightly deviations. Nevertheless, the individual parts used for this are simple, inexpensive and also easy to assemble.

In Fig. 5 you can see an arrangement that allows a height adjustment of the horizontal support rod relative to vertical supports 3. As in other exemplary embodiments, the coupling rod 4 enters through a slot 3b into a coupling piece 3c located inside the hollow holding rod 3, which can be fixed with the aid of a clamping screw 3d. After loosening the clamping screw 3d, the coupling piece 3c can be moved in the support, that is to say adjusted in height, the holding rod 4 being able to act on it or can be attached to it subsequently.

Such an embodiment is also possible in the exemplary embodiments according to FIGS. 2, 7, 8 and 10 if the wall connections 3a have a sufficient length. An adaptation to different dimensions, tolerances or even different dimensions of supports and cabin walls 2 is thus possible in a simple manner.

The holding rod 1 to be arranged in the use position in a substantially horizontal plane and orientation runs in a large number of cases above the edge of a partition wall 2 for shower cubicles, specifically in the plane of this partition wall 2. For connecting several partition walls, in particular at an angle to one another, via these holding rods 1 and Also for connecting the support rods 1 to supports 3 or support profiles, the support rod 1 has at least on one of its end faces, in many cases for a two-sided connection on its two end faces an axially projecting coupling rod 4, the cross-section of which is smaller than that of the support rod 1 is. These coupling rods 4 can be adjusted in the axial direction and relative to the respective holding rod 1 be set in order to be able to easily compensate for dimensional deviations.
