EP2423394B1 - Drainage channel for showers flush with the floor - Google Patents

Description

The invention relates to a gutter for a floor-level shower, with a gutter body, at least one gutter end piece, which is releasably connectable to the gutter body, and with at least one rod-like body which extends in the mounted state along and within the inlet opening of the gutter body.

Drainage channels for floor-level showers are known. They usually comprise a gutter body made of stainless steel, on which a drain neck is formed or welded and in which a grid is inserted. The water from the shower flows over the floor, which is typically covered with tiles or natural stone slabs, and enters the gutter through the grate. The gutter of the channel body ultimately leads the water to a drain.

Such gutters are installed in the ground, with the grate up close to about the floor covering the shower. The installation of a shower tray or the like is not required, so that the peripheral edge of the shower tray, which often acts disturbing deleted.

Gullies for floor-level showers have to be adapted in a special way to the special installation site, since the substructure, the floor covering made of tiles or natural stone and the connection to the sewer can vary from case to case and usually only a low overall height is available. Above all, such Drain channels ensure a safe drainage of the water, in which the lower floor construction, consisting of screed and possibly thermal insulation, is not soaked. In addition, they should be aesthetically integrated into the ground.

Due to different customer requirements and different space in shower baths different lengths shower channel body are offered. Conventional shower tray bases are available, for example, with a uniform width of about 140 mm in stepped lengths of 750 mm, 800 mm, 900 mm, 1000 mm and 1200 mm. As a result, a large number of different shower channels are produced and kept in stock. The scope of a particular conventional shower channel is usually limited.

In addition, there is sometimes the customer request that the surface of the shower channel visible in the completely installed state, that is to say in particular its grate, is made as small or narrow as possible. The shower channel is then less noticeable or looks more elegant in its aesthetic appearance.

The DE 20 2010 002 011 U1 discloses a gutter in which the closest prior art can be seen. This document corresponds to the preamble of claim 1. The recess of the gutter is limited by opposing longitudinal walls and thus integrally formed transverse walls. On the longitudinal and transverse walls, a circumferential flange connects to the upper side, which rests in the region of the transverse walls on pedestal holders, which are detachably connected to the gutter. In the recess of the gutter several bridge-like insert parts are used. The respective insert part is provided with approximately vertical support surfaces to the approximately vertical support surfaces (longitudinal walls) of the gutter and inserted with inclined support surfaces on an upper portion of approximately V-shaped tapered support surfaces of the gutter. Furthermore, the gutter has a cross-sectionally U-shaped cover plate, which is slipped onto the bridge-like insert parts, so that in the assembled state on both sides of the cover plate to the edges of the recess of the gutter each a discharge gap remains open. The respective insert part has a thread into which a leveling screw with support head is screwed in as a height-adjustable support for the cover plate.

The DE 20 2008 003 009 U1 describes a shower floor element, which is formed from at least two superposed foam plate parts and has a marginal grading. Furthermore, the shower floor element comprises a drain housing and a film-like, sealing element attached at the edge. The drain housing is assigned to a corner region of the shower floor element. Furthermore, the shower tray element comprises elongated drainage channels, which are arranged on two intersecting edges of the shower tray element in the region of the peripheral graduation and are connected to the drainage housing. The drainage channels may be formed as a plastic part, in particular as plastic profiles and at its end facing away from the drain housing have a Endverschlussteil.

The EP 1 779 754 A1 discloses a shower board with a shower floor panel and a floor drainage system. The floor drainage system has one or more extruded parts of predetermined shape as a channel element (s).

The EP 1 630 309 A1 discloses a floor gutter for showers. The Bodenablaufrinne has a lower gutter body, which is provided at its lowest point with a drain neck. In addition, the floor drainage channel has a second (upper) channel body, in the channel-shaped depression of which a grate is inserted and which is inserted into the lower channel body. The upper channel body has at its lowest point also an outlet nozzle, said outlet nozzle is arranged so that it penetrates into the outlet nozzle of the lower channel body when the upper channel body is inserted into the lower channel body.

The present invention has for its object to provide a gutter for floor-level showers that can be produced more cost-effectively than conventional shower channels and in the fully installed state has a relatively small visible surface at high drainage capacity.

This object is achieved by a drainage channel (shower channel) with the features of claim 1.

The gutter according to the invention is characterized in that the at least one rod-like body has the function of a grate, that the at least one gutter end piece is provided with a groove associated with the gasket body, and that the at least one gutter end piece at least one recess or holder for supporting one end of the rod-like Body has.

The gutter according to the invention (shower channel) is based on the idea of their gutter arbitrarily long, for example in a length in the range of 1200 mm to 2000 mm, so that the gutter body shortened prior to installation of the gutter according to the customer request by means of a saw or other cutting tool can be. The gutter body or gutter can be optimally adapted in this way to a tile or Bodenplattenformat or a joint grid. Also, by appropriate cutting (shortening) of the gutter body of the gutter according to the invention an optimal adaptation to the horizontal extent of serving as a shower screen glass or to the width of a shower room niche possible. It must be produced by the manufacturer so no special lengths more. The open end of the suitably cut gutter body is sealed in each case liquid-tight by means of the associated gutter end piece and the associated seal.

By limiting the number of different gutter body lengths to one, two, three or at most four specific lengths, lower production costs and lower logistics costs can be achieved by the manufacturer of the shower channels. Likewise, an optimized storage logistics can be achieved in this case with dealers supplied with the shower channels according to the invention.

Furthermore, the gutter according to the invention is based on the idea of preferably providing a single rod-like body or as few, for example two or three, rod-like bodies (grate bars) at the top of the inlet opening of the gutter instead of a typically plate-shaped grate. The grate bar or the grate bars extend in the mounted state along and within the inlet opening of the channel body and are mounted in or on the gutter end piece. This idea takes into account and favors the variable length adaptability of the gutter according to the invention. The respective rod-shaped body (grate bar) is preferably longer than the channel body and can also be cut to the required length depending on the desired length of the gutter. In particular, the use of a single rod-like body or possibly less rod-like body (grate bars) promotes a reduction of visible in the fully installed state surface of the gutter. Preferably, only the single or the few rod-like bodies of the gutter (shower channel) are visible in the finished state of the floor-level shower substantially. When using several rod-like bodies (grate bars), the distance between adjacent grate bars is in particular at most 8 mm, preferably at most 6 mm and particularly preferably at most 4 mm. In particular, the solution according to the invention makes possible a very narrow design of a shower channel with nevertheless high drainage capacity in comparison to conventional shower channels having a plate-shaped grate. In addition, the solution according to the invention also enables a saving of material costs in relation to the otherwise conventional plate-shaped stainless steel grid.

In order to allow a flush fit to achieve a flush finish of the gutter to different thickness floor tiles or floor panels, a preferred embodiment of the drainage channel according to the invention provides that the storage of the rod-shaped body serving recess or holder is provided with an adjustment by means the height level of the rod-like body can be adjusted relative to the gutter body or its top.

In order to make the handling of the adjustment as simple as possible, preferably a tool-free handling of the adjustment is possible, provides a further embodiment that the adjustment is positively connected in the recess of the gutter end piece or positively connected to the holder of the gutter tail. A particularly preferred embodiment consists in the fact that the recess has a tooth-like profile for the positive reception of the adjusting element and gradual height adjustment of the rod-like body. The tooth-like profile may have a relatively fine pitch, so that if necessary, a correspondingly fine height adjustment of the rod-like body can be done.

A further advantageous embodiment of the gutter according to the invention is that the gutter end piece has a recess facing the gutter body into which an end portion of the gutter body can be inserted, wherein the seal associated with the gutter body is arranged in the recess. The recess of the gutter tail has in particular a the installation of the gutter tail facilitating leadership function. Furthermore, the arrangement of the seal in the recess makes it possible to ensure a reliable attachment of the seal to the end face of the channel body to be sealed.

The detachable connection of gutter body and gutter tail can be performed for example as a frictional connector. An additional fixation of the gutter end piece on the gutter body can be done after the connection of the gutter to a sewer pipe by introducing cement screed in the surrounding the gutter bottom area. However, an embodiment in which the gutter end piece is detachably connected to the gutter body by means of a screw connection is particularly preferred. This makes it possible to ensure an absolutely reliable sealing of the end of the gutter body.

An advantageous development of the gutter according to the invention provides in this context that the channel body has parallel to its longitudinal axis extending grooves, holes or channels for attachment of tapping screws. Preferably, these grooves or channels extend over the entire length of the channel body, so that regardless of where the channel body is optionally shortened for length adjustment of the gutter, the tapping screws can always be screwed into the grooves or channels cutting.

The tops of the flanges 2.3 are substantially planar. But you can also, as in particular Fig. 22 can be seen, a profiling or structure, in particular in the form of extending in the longitudinal direction of the gutter 1 grooves 2.31. This profiling or structure 2.31 improves the connection of the gutter 1 with sealing materials, such as liquid-applied sealing film (so-called liquid film) or tile or natural stone adhesives.

Below the flanges 2.3, the channel body 2 has grooves or channels 2.5, which extend over the entire length of the channel body 2 and parallel to its longitudinal axis. In the channels 2.5 or longitudinal grooves screws 8 are screwed to fix the gutter end pieces 3 on the gutter body (see. Fig. 19 ). For receiving the screws 8, the respective gutter end piece 3 has through holes 3.5 which are aligned with the channels 2.5 or longitudinal grooves of the gutter body 2. The screws 8 are preferably tapping screws.

The longitudinal grooves or channels 2.5 are preferably formed on the outer sides of hollow profile walls 2.10, which are each integrally formed on the underside of one of the flanges 2.3 and the outside of the U-shaped profile section 2.1 and thus define a tubular channel. This embodiment gives the inventive gutter 1 an advantageously high flexural rigidity.

The channels 2.5 are formed as open channels; they each have an outwardly directed, continuous longitudinal slot 2.51.
