Description

The present invention relates to a drainage device for a tile floor according to the preamble of claim 1.

A drainage device of the aforementioned type is known from European published patent application EP-A-0 763 634, which describes a support means which can be introduced into a drain pan, to which screed and tiles can be applied. This support means has a flange which can transition to the center in a falling portion, so that the support means can serve as a tilting means. The support means can be connected via snap fasteners with the drain pot.

Another drain device is known from German patent application DE 36 27 807 A1. In the drainage device described therein, the drainage unit consists of a drain pot made of plastic, which is poured into a concrete slab, which is square when installed in the plan view and has a side dimension of 90 cm. On its upper side, this concrete slab on inclined surfaces, which decrease from outside to inside, so to the inlet opening of the drain pot in height. The square concrete slab can serve as a foundation for the tile floor of a shower. The applied to the concrete slab tiles thus have the necessary slope to direct on the tiles incident water to the water inlet opening of the drain pot.

A disadvantage of such a prior art proves that the drain unit forms with the serving as a tilting concrete slab a factory-fixed unit, so that the attachment of the drainage device according to the invention is connected on site due to the weight and bulkiness of the concrete slab with considerable difficulties.

The problem underlying the present invention is to provide a drain device of the type mentioned, which is of variable construction and allow easier on-site assembly.

This is inventively achieved by a drain device of the type mentioned above with the characterizing features of claim 1. The subclaims relate to preferred developments of the invention.

According to the characterizing part of claim 1, it is provided that the inclination means comprise stand means, which allow a listing of inclination means in the bottom region of a room. These stand means can be designed as support feet. Suitable stand means allow that after the separate installation of the drain unit, the inclination means are placed around the drain unit, for example, in particular, without additional connecting means for the connection of drain unit and inclination means are required.

The subsequent connection of the inclination means with the drainage unit makes it possible that the drainage unit can be mounted separately first. Subsequently, the inclination means are connected to the drainage unit, whereupon the tiles can be arranged above the inclination means.

According to the invention, the drainage unit can have an inlet collar surrounding the water inlet opening.

Furthermore, gratings can be attached to this inlet collar at the side facing away from the water inlet opening outer sides, which extend from the inlet collar in the use position substantially horizontally outward. Advantageously, the inclination means on support strips, which can be placed on the grid. Here, the grid and the support strips serve as connecting means. By laying on the grid support strips results in a simple connection between the inclination means and the drain unit. In particular, the grids and the support strips can be provided with gaps in such a way that screed can be applied to the floor of a room through the grids.

According to a preferred embodiment of the present invention, the inclination means on honeycomb elements, which are preferably formed by at an angle of about 120 ° to each other standing strips. The honeycomb elements can also be shaped so that screed can be applied through the honeycomb elements to the bottom of a room in which the drainage device is to be attached. In particular, tiles can then be applied to the screed in such a way that the inclination of the honeycomb elements encompassed by the inclining means predetermines the desired inclination of the screed so that the tiles applied to the screed likewise have the desired inclination.

In an alternative embodiment it can be provided that the inclination means have gratings, which are preferably connectable to the inlet collar. Here, the grid can be omitted on the inlet collar.

According to the invention, there is the possibility that the drainage device comprises four inclination means. Here, the inlet collar may have a substantially square outline, in particular, the adjoining the inlet collar grid may have a square outer contour. This opens up the possibility that the four inclination means in the use position of the discharge device in each case abut at least on one of the sides of the inlet collar with a square outline. The inlet collar of the drainage unit is thus surrounded on all sides by the inclination means, so that inclination means are arranged on all sides surrounding the water inlet opening, which ensure the desired inclination of the tiles to be applied.

According to a preferred embodiment of the present invention, the inlet collar and / or the inclination means are designed to be height adjustable. It can be provided that height-adjustable support feet are mounted on the underside of the inlet collar, in particular four height-adjustable support legs substantially in the corners of a square. Furthermore, it can be provided that height-adjustable support feet are attached to the underside of the inclination means, in particular two support feet on each of the inclination means. The height adjustability of the inlet collar ensures that the drainage unit can be adapted to local conditions. The height adjustment of the inclination means ensures the optimum adjustment of the inclination in conjunction with the height adjustment of the inlet collar. The realization of the height adjustment by height-adjustable support legs is a simple and reliable measure.

Advantageously, the inlet collar has on its upper side an inlet region which surrounds the water inlet opening and is inclined in the direction of the water inlet opening such that water impinging on the inlet collar is caused to flow in the direction of the water inlet opening. Thus, the desired inclination of the surface surrounding the water inlet opening is ensured even in the region of the inlet collar.

It can be seen from FIGS. 1 and 3 that a drainage device according to the invention comprises a drainage unit 1 and tilting means 2 which can be connected to it. In this case, the drain unit 1 is surrounded by four inclination means 2 connected to it and one another.

The drain unit 1 comprises a drain pot 3, which has on its upper side a water inlet opening 4 with an inlet collar 5 surrounding this water inlet opening 4. The inlet collar 5 is a substantially flat part with a rectangular outline, which has on its upper side a flat, slightly funnel-shaped inlet region 6 concentrically the Water inlet opening 4 surrounds and in the inlet region 6 befindliches water to the water inlet opening 4 feeds.

The drain pot 3 has in its lower region on a lower drain opening 7, which can be fluidly connected to a drain pipe. In particular, the underside of the drain pot 3 can be sealingly introduced into a corresponding receptacle connected to a drain pipe.

In particular, from Fig. 2 and Fig. 3 it can be seen that on the underside of the inlet collar 5 four support feet 8 are mounted, which are adjustable in height. Furthermore, are connected to the inlet collar 5 of this outwardly projecting grid 9, which, as can be seen in particular in FIG. 3, surrounding the inlet collar circumferentially. The grids 9 have a width in the horizontal direction, which corresponds approximately to half the width of the inlet collar 5.

In the illustrated embodiment of the present invention, four inclination means 2 are provided, which are attached from each of the sides of the inlet collar 5 with a square outline and the surrounding grids 9. Each of the inclination means 2 in this case has two outer support feet 10 designed as a stand means, which are likewise height-adjustable. Furthermore, each of the tilting means 2 has an outer edge 11 to which honeycomb elements 12 extending inwardly from the outer edge are attached. The honeycomb elements 12 are formed by interconnected at an angle of about 120 ° web-shaped strips. From the inner edge of the honeycomb elements 12 extend from the outer edge 11 projecting away support strips 13 in the direction of the inlet collar 5. The support strips 13 form together with the grids 9 connecting means for the attachment of the inclination means 2 to the drain unit. 1

It is according to the invention the possibility that each of the inclination means 2 more than two, for example four support legs 10, so that the inclination means 2, without being attached by additional connecting means to the drain unit 1, placed on the floor of the room around the drain unit 1 around can be.

In the assembled state of the drain device are the support strips 13 on the gratings 9. In the illustrated embodiment, extending from each of the inclination means 2 three mutually parallel and spaced-apart support strips 13 in the direction of the inlet collar 5. Here, each of the two outer support strips at their inlet collar 5 facing the ends recesses 14, which partially serve to surround the corner of the inlet collar 5 and partly serve to surround the edges of the ends of support strips 13 adjacent inclination means 2.

A drainage device according to the invention can be installed such that first the drainage unit is mounted. For this purpose, for example, the lower end of the drain pot 3 is connected tightly with a drain pipe. In this case, the height of the support feet 8 connected to the inlet collar 5 can be adjusted in accordance with the spatial conditions in the room in which the drainage device is to be installed. Subsequently, the four inclination means 2 are placed with their support strips 13 on the grid 9 of the drain unit 1, in which case the corners of the inlet collar 5 each of two at an angle of 90 ° clashing support strips 13, the two go out adjacent inclination means 2, are embraced. Following this, the heights of the supporting feet 10 connected to the inclining means 2 can be adjusted such that the honeycomb elements 12 and the supporting strips 13 have an inclination in the direction of the inlet collar 5. Subsequently, for example, the floor of the room around the drain pot 3 around with screed or the like can be filled so that the screed partially protrudes through the grid 9 and the honeycomb elements 12 upwards. Subsequently, tiles can be applied to this screed in the area of the honeycomb elements 12 and the grid 9, the tiles guaranteeing drainage of water located on the tiles in the direction of the inlet collar 5 and the water inlet opening 4 due to the slope ensured by the inclination means 2.

FIG. 4 and FIG. 5 show a further embodiment of a discharge device according to the invention, in which the same parts are provided with the same reference numerals as in FIG. 1 to FIG. 3. In the embodiment according to FIG. 4 and FIG Inclination means 2 provided. However, these inclination means 2 have instead of honeycomb elements 12 grid 15. These gratings are fastened, for example, to the feet 10 or also to the outer edge 11 of the inclination means 2.

In the embodiment according to FIGS. 4 and 5, the inlet collar 5 does not have a grid attached to its outside. Rather, the grids 15 of the inclination means 2 are connected directly to the inlet collar 5. For this purpose, the inlet collar 5 has a circumferential upwardly open receiving groove 16, in the inside edges of the grid 15 can be inserted.

In the embodiment according to FIGS. 4 and 5, a slightly differently shaped drain pot 3 is depicted. However, in terms of its function relevant to the present invention, this drain pot corresponds to the drain pot depicted in FIGS. 1 to 3. The grids 15 may in particular be made of wire.

It is inventively possible to use instead of the grid 15 or the honeycomb elements 12 flat non-perforated or only slightly perforated elements. These flat elements could be formed in particular as Hartschaumviertel or halves. These hard foam quarters or halves could in particular also do without support feet or without height adjustment simply by having a corresponding thickness and a corresponding inclination towards the center. These hard foam quarters or hard foam halves could simply be placed on the screed surrounding the drain opening.

Furthermore, according to the invention, it is possible to use quick-setting cement or the like instead of screed. In particular, styrofoam balls or the like could also be included in the quick-setting cement for sound insulation.

According to the invention, there is also the possibility that the drain pot does not have a downwardly pointing discharge opening but rather a discharge opening which leads to the side.

Furthermore, according to the invention there is the possibility that the inlet collar 5 has no square outer contour but a differently shaped outer contour, for example a circular outer contour.
