Description

The invention relates to a sanitary pipe, as used in particular as shower spout for a shower head.

A common type of shower arm is a hollow shower arm made of brass, whose hollow channel acts as a water-bearing channel to a mounted shower head. Such shower arms made of a brass housing have a relatively high weight. The water passed directly into contact with the brass housing material.

The invention is based on the technical problem of providing a sanitary pipe, which can be realized with comparatively low weight and with which a contact of water carried to a housing metal can be avoided.

The invention solves this problem by providing a sanitary pipe with the features of claim 1. This sanitary pipe has a rigid, hollow line housing with a base body and a housing wall attached thereto. In the hollow conduit housing at least one flexible conduit made of a bendable conduit material is inserted.

The insertion of the flexible conduit in the hollow conduit housing can be done easily before closing the conduit housing by attaching the housing wall to the body. The inserted line acts as a water-bearing channel and avoids any contact with the typically metallic material of the line housing for the water performed. Thus, the line housing can be made for example as a hollow zinc diecasting. Of particular advantage is the use of bendable material for the inserted line. Because of this, the line can flexibly follow any, for example, curved or angled course of the line housing, without having to be tuned exactly in advance in their shape and length to the shape of the line housing, as in an alternative conceivable use of a rigid pipe part Metal or plastic would be the case.

Advantageous alternative developments of the invention include the use of a bendable plastic hose line or a bendable metal line for the flexible line.

In a development of the invention, the sanitary conduit has means for fixing or lateral guiding of the respective flexible conduit. In this way, the line can be kept in a defined position in the line housing.

In a development of the invention, the sanitary pipe has at least one end of the flexible pipe to a connection nipple, which preferably consists of a rigid plastic or metal material.

In one embodiment of the invention, a plurality of flexible lines are fluidly arranged in parallel and juxtaposed in the line housing. As a result, hot water and cold water, for example, can be routed separately in the sanitary pipe, or shower water can be fed separately to separate shower jet areas of a coupled shower head. In a further embodiment, a multi-terminal nipple is provided, which has a plurality of connection openings, which are coupled to one end of each of the flexible lines. The connection openings are fluidically connected to a common outlet or inlet opening or alternatively to separate outlet or inlet openings of the multi-terminal nipple. In the former case, water supplied via the inlet opening can be split up onto the several connected flexible lines or can be brought together separately in the multi-terminal nipple via the flexible lines. In the latter case, separately separate shower spray areas can be supplied via the outlet openings.

In an advantageous embodiment of the invention, the sanitary pipe includes a shower spout for a shower head. In a further embodiment, in such an effervescent armature, the multi-terminal nipple forms a connection for the coupled flexible lines to a shower head of the shower head.

In one embodiment of the invention, of the plurality of fluidically parallel flexible lines, a first can be coupled to a first shower spray area of the shower head and a second to a second shower shower area which is separate from the first. This allows separate guidance of shower water in the sanitary pipe to the different shower jet areas. If the outlet side of the multi-terminal nipple is provided, the flexible lines can be coupled to the separate shower areas over this.

In a further embodiment of the invention, the sanitary line for use in a shower head on a shower-side section and an opposite this extending angled shower arm section. Thus, the shower-wall-side section may be e.g. be provided to be mounted substantially vertically extending on a solid wall of a shower, while the shower arm portion thereof projects substantially horizontally extending and carries the shower head.

This in Fig. 1 Shower system shown perspectively in an assembly exploded view includes a sanitary pipe according to the invention 1, which leads from a mixer 2 to a showerhead 3 and is composed in two parts of a wall-side portion 1a and one of them substantially perpendicular abracing shower arm portion 1b. The two sections 1a, 1b are coupled to each other via a wall bracket 4, with which the sanitary pipe 1 can be attached to a fixed wall of a shower room in a conventional manner, so that the wall-side portion 1a substantially vertically and the shower arm portion 1b substantially horizontally extends.

The only schematically indicated mixer 2 has in the usual way two separate water inlets 5, 6 for cold water or hot water and a quantity and temperature control, not shown, with which the user can set the amount of water and the water temperature. In a conventional manner, a hand shower 7 is additionally connected to the mixer 2.

In the embodiment of Fig. 1 If the mixing of cold water and hot water in the mixer 2 takes place, and the corresponding mixed water is passed to the hand shower 7 and the overhead shower 3. For this purpose, its wall-side portion 1a, for example, made of zinc die-cast, rigid, hollow wall section line housing 8, in which a single flexible Line 9 of a bendable conduit material, such as a bendable plastic tube material or a bendable metal material, is inserted. The wall section conduit housing 8 has a substantially rectangular cross-section and is open along its wall side in a width which allows insertion of the flexible conduit 9 into the housing cavity so that it does not need to be inserted axially from the housing face.

The shower arm pipe section 1b also includes a rigid hollow conduit housing 10 made, for example, as a zinc diecasting part, into which a flexible conduit, not shown, of a bendable conduit material is inserted. This flexible conduit discharges into the overhead shower 3 on the outlet side and is coupled on the inlet side by means of a customary line connection in the region of the wall mount 4 to the outlet-side end of the line 9 received in the wall line section 1a.

The line housing 10 of the shower arm section 1b consists of a main body 10a and a housing wall realized here as the upper-side housing cover 10b, which is detachably attached to the main body 10a by means of screw connections 11. When the housing cover 10b is removed, the flexble shower arm cable is inserted into the shower arm base body 10a, whereby it is correspondingly bent by approximately 90 ° in the bending area of the main body 10a. Through the use of bendable conduit material, the bend can be made with the insertion of the flexible conduit into the housing body 10a, so that it is not necessary to prefabricate a conduit with this bend. After inserting the flexible line of the housing cover 10b is placed on the base body 10a and fixed by means of the screw 11 to him. Depending on requirements, the inserted line can be fixed by means of appropriate fixing or guiding means on the housing base body 10a or at least guided laterally. The shower arm duct and the wall-side duct 9 may each be provided at the end with suitable connection nipples in order to connect them to one another and / or to provide suitable connections to the overhead shower 3 on the one hand and the mixer tap 2 on the other hand.

The FIGS. 2 and 3 illustrate a variant of the shower system of Fig. 1 with the components of interest here. In this system variant, shower water is led from a mixer tap to two different shower jet areas of an overhead shower 3 '. The shower system of the FIGS. 2 and 3 has for this purpose a sanitary pipe according to the invention 1 'in a two-channel design. Similar to the system of Fig. 1 the sanitary pipe 1 'consists of a wall-side section 1'a and an overhead shower-side shower arm section 1'b, which are coupled together mechanically and fluidically via a wall mount 4'. The wall-side section 1'a in turn includes a rigid, hollow conduit housing 8 ', which is designed to be open on its wall side, so that two parallel flexible lines 9a, 9b can be inserted from this side.

Analogously, the shower arm section 1'b comprises a rigid, hollow conduit housing 10 ', for example made of die-cast zinc, with a base body 10'a and a housing cover 10'b mounted thereon and fixed thereto. Fig. 3 shows the shower arm base body 10'a with mounted overhead shower 3 'in a merely design with respect to the system of Fig. 2 slightly modified version. In the view of Fig. 3 is the housing cover 10'b removed, which can be seen that and as in the shower arm housing main body 10'a two separate, parallel, flexible lines 12a, 12b are inserted. They are guided laterally by webs 13, which are formed on inner side walls of the housing body 10'a in pairs opposite each other and provide if necessary, screw openings, in which screws can be screwed, for example, for fastening the housing cover 10'b. Additionally or alternatively, the flexible lines 12a, 12b can be fixed by means of corresponding fixing means on the housing base body 10'a.

Since the flexible lines 12a, 12b are made of bendable plastic or metal material, they can easily follow a bend 14, with which the shower arm 10'a from a mounted state in a shower about vertical, entrance side course in an obliquely forward a horizontal main component. At the entrance end of the shower arm 10'a is in the in Fig. 3 variant shown, a connection element 15 is provided, with which the shower arm 10'a can be coupled to a wall-side line section or attached directly to a wall of a shower room. At this inlet-side end, the flexible lines 12a, 12b terminate with a respective connection nipple 16a, 16b. At the opposite, head-shower end, the flexible lines 12a, 12b open into a double connection nipple 17.

Fig. 4 shows a variant of the system of FIGS. 2 and 3 in which a sanitary line according to the invention 1 "is used, the two flexible lines 12a, 12b of bendable line material in one piece from a mixer not shown to are led to the overhead shower 3 ', wherein for better understanding of functionally equivalent, not necessarily identical elements, the same reference numerals are used as in the FIGS. 2 and 3 , In other words, the two flexible lines 12a, 12b extend for two separate spray jet areas along a wall-side section 1 "a and a subsequent shower arm section 1" b. For this purpose, the wall-side section 1 "a includes a rigid, hollow conduit housing 8" open on the wall side, which is connected to the housing base body 10'a of the shower arm section 1 "b via a connection element 15 ' Sanitary pipe 1 "on the wall of a shower room. Alternatively, the wall-side line housing 8 "may be formed integrally with the housing base body 10'a of the shower arm section 1" b.

At the inlet end, the two flexible lines 12a, 12b are again provided with a respective connection nipple 16'a, 16'b, via which they can be connected to the mixer tap, not shown. At the corresponding end region of the wall-side line housing 8 "means 18 for guiding or fixing the two connection nipples 16'a, 16'b are provided.

Out Fig. 5 It can be seen how the two parallel flexible lines 12a, 12b are accommodated closely adjacent one another and guided laterally by the webs 13 in the housing base body 10'a of the shower arm section. It shows Fig. 5 a cross-section at height just before the confluence of the two flexible lines 12a, 12b in the double connection nipple 17th

The two-channel version of the plumbing, as above to the Fig. 2 to 5 can therefore be used to separately supplied mixed shower water in a mixer tap two separate shower spray areas of a correspondingly configured shower head, which allows the establishment of different spray jet characteristics with these separate shower jet areas. Alternatively, it can be used to run cold or hot water separately or to run mixed shower water over the two ducts in a faucet parallel to a common shower jet area of the overhead shower. In the latter case, the water with twice the capacity can be compared with the use of only one line same flow cross-section lead to the shower head.

It is understood that the invention also includes multi-channel sanitary pipes with three or more fluidly parallel flexible conduits made of bendable cable material. These can be used, for example, to individually supply each of three or more separate shower spray areas of a correspondingly configured shower head with water. If necessary, corresponding multi-terminal nipples may be provided with three or more ports for the three or more flexible conduits instead of the aforementioned dual-port nipple.

Fig. 6 shows in longitudinal section a connection nipple 19, as it is usable for the sanitary pipe according to the invention, for example, as the inlet-side connection nipple 16a, 16b, 16'a, 16'b in the shower systems of Fig. 2 to 4 , The connection nipple 19 is in an in Fig. 6 provided right area with a fir-tree hose holding profile 20 and then has a stop ring 21 thereon. The connection nipple 19 is inserted with its line holding profile 20 to the stop ring 21 in an associated flexible line. On his in Fig. 6 left side, the connection nipple 19 has an annular groove 22 for a ring seal to be used and an outer profile 23, with which it can be performed or fixed, for example, to a housing portion of the relevant sanitary line.

How out Fig. 7 to recognize the nipple 19 'is inserted with a fir-tree-shaped retaining profile up to a stop ring 21' in the end of a flexible conduit 24. A surrounding ferrule member 25 secures the connection of flexible conduit 24 and nipple 19 '.

Fig. 8 shows an embodiment in which a wall support member 26 is fastened by means of screw 27 to a hollow conduit housing portion 28 which is part of a sanitary line according to the invention and in which in turn at least one associated flexible conduit 29 is inserted from a bendable conduit material. The flexible line 29 is plugged onto a connection nipple 30 at the end shown. The screw 27 serve this same time, as from Fig. 8 can be seen to keep the connection nipple 30 in the line housing 28 and secure the connection of the flexible line 29 and nipple 30.

The FIGS. 9 and 10 illustrate an advantageous embodiment of the aforementioned double connection nipple 17 through which the two separate flexible lines 12a, 12b in the two-channel shower arm in the shower head 3 'open and can be made of a rigid plastic material, for example. As can be seen, the double connection nipple has two essentially parallel connection openings 31 a, 31 b and two corresponding outlet openings 32 a, 32 b into which one of the two connection openings 31 a, 31 b opens and which is substantially perpendicular to the connection openings 31 a, 31 b out of the nipple 17. The outlet opening 32a forms a central channel and the outlet opening 32b forms an annular channel. At the double connection nipple 17, a substantially annular flange 33 is formed, through which the nipple 17 can be fixed to the associated shower head. The two separate outlet openings 32a, 32b then lead in the installed state of the nipple 17 to the various associated shower jet areas of the overhead shower.

The FIGS. 11 and 12 illustrate as a further embodiment of the invention a sanitary conduit formed as a directly wall-mountable shower arm 1 '"For this purpose, the shower arm 1'" in a rear end region on a mounting plate 34, with which it can be attached directly to a shower room wall to mounted state substantially horizontally projecting from this wall.
