EP2392739B1 - Drain with height adjustable element - Google Patents

Description

The invention relates to a drainage sequence for installation in a bottom opening of a shower enclosure, comprising an inlet part to be inserted into the bottom opening with an upwardly open inlet opening into which a cover element is inserted which is height-adjustable relative to the inlet opening and covers the inlet opening, leaving at least one level opening.

An inlet grate with a height adjustment is off EP 1 782 721 (Figure 8). The document shows a grate with height-adjustable feet, via which it is supported in the shower channel. The feet are height-adjustable attached to the grate. On the underside of the grate threaded rods are fixed, on each of which a sleeve-shaped hex nut is screwed with support disc. The height adjustment is done by turning with the hexagon nut. The support of the feet on the shower channel requires a relatively large length of the threaded rod. The rust can slip inside the opening, as there is no connection with the other parts of the shower tray. A lock is not possible.

This document EP 1 782 721 is considered to be the closest prior art.

In DE 20 2006 009404 U1 is described a drainage channel with adjustment elements for balconies and terraces. It is not a cover element or rust, but the entire drainage channel in height adjustable. A threaded rod with foot is screwed into a arranged on the underside of the groove threaded sleeve and fixed with a located on the top of the groove locknut. The drainage channel is thus held together from below and from above and can not simply be raised and lowered like the gridiron. Also, the adjustment in height requires more work steps, namely the loosening or turning off the lock nut, turning the foot of the threaded rod and only then re-screwing the lock nut.

A drainage process according to US 4,694,513 A shows a round cover element (rust, reference numeral 90), which is to be connected via screws with an upper part of a three-piece inlet element. An adjustability in height is not provided. Below the inlet element are screwed together threaded sleeves with collar.

The font DE 20 2006 014959 U1 shows a shower channel, comprising a frame and in the frame from above usable support with glass plate, wherein the frame and the outer edge of the carrier form a circumferential inlet slot.

The carrier is mounted on height-adjustable spacers on the bottom of a channel-shaped base body.

The font DE 20 2008 003050 U1 describes a shower tray with shower channel having a gutter section for draining a shower area. The shower plate is supported on a support frame with height-adjustable foot elements, wherein at least one of the foot elements for the shower channel is attached to the support frame.

At the document DE 203 02 899 U1 it is a drainage rack for Drainage eaves for drainage of a balcony or a terrace, comprising a frame which is supported on height adjustable and distance adjustable support feet on a shell plate, wherein a shaft of the support leg is formed as a threaded shaft.

The font JP 203 253743 A describes a height-adjustable, placed on a concrete block via thread-like support legs block body. The support foot has a threaded shaft with differently shaped threaded sections.

For the invention, the task is to specify an adjustability of the cover member relative to the bottom opening and the inlet part, so that a variety of heights can be considered in a simple manner, with just a few parts an easy-to-see and also readjustable height adjustment and facilitates the lifting of the cover element is.

• das Deckelelement ist an seiner Unterseite mit mehreren Gewindehülsen fest verbunden, die ein Innengewinde aufweisen,
• in die Innengewinde der Gewindehülsen sind Gewindemuffen mit Aussengewinde und Innenhohlraum verstellbar auf einen Teil ihrer Länge eingedreht, die nach unten die Gewindehülsen überragen,
• das Einlaufteil ist mit Positionsbolzen versehen, die von dem Innenhohlraum der Gewindemuffen überstülpt sind,
• die Positionsbolzen sind zylindrisch gerundet und verjüngen sich nach oben, jedoch spielfrei von den Gewindemuffen überstülpt sind,
• wobei eine Gewindehülse, eine Gewindemuffe und ein Positionsbolzen zusammen ein Verstellelement bilden.

The object is achieved with a height-adjustable drainage process with the following features:

• the cover element is firmly connected on its underside with a plurality of threaded sleeves, which have an internal thread,
• into the internal threads of the threaded sleeves threaded sleeves with external thread and internal cavity are adjustably screwed on a part of their length, which project beyond the threaded sleeves,
• the inlet part is provided with position bolts that are slipped over from the internal cavity of the threaded sockets,
• the position bolts are rounded in a cylindrical shape and taper upwards, but are slipped over without play by the threaded sockets,
• wherein a threaded sleeve, a threaded sleeve and a position bolt together form an adjusting element.

The position bolts can be connected, for example, with a flange ring of the inlet part. Metals are particularly suitable as material for the position bolts, but plastic parts can also be used.

The cover element can be constructed, for example, as a grate with surface openings or as a closed cover element with an angled edge flange, the drainage water running between edge flange and surrounding parts.

The position bolt is preferably rounded cylindrical and tapers upwards in the tip area, so that no tilting can occur when pulling up, for example for readjusting.

In particular, it is advantageous that the lid element can be assigned to its length selectable removable threaded sleeves. So For example, a kit can be supplied, which contains two or more threaded sleeves without substantial cost increase, so that there is a greater margin for the required increase.

The threaded sleeve can additionally be locked with a nut.

In the case of a round inlet opening, at least three or four adjusting elements are arranged radially symmetrically peripherally on the insert part.

The inventive principle can also be used with an inlet opening in the form of a longitudinal channel with U-shaped, provided with a bottom channel-shaped inlet part, wherein at least two adjusting connect the bottom of the inlet part with the upper part of the elongated cover element or the channel.

Possibilities of adjustability, on average acc. Fig. 1 (Detail C);

FIG. 4 : a section through an adjustment.

The terms "top" and "bottom" used below are defined by the usual arrangement of an inlet in the drawn representation of the shower drains, namely with the Cover element "top" and the inlet opening "bottom". However, it should be noted that the parts of the adjustment described below can also be arranged in the reverse order from "bottom to top".

In FIG. 1 is a cross-section through an embodiment of a drainage outlet 100 for installation in a bottom opening 4 of a shower stall shown.

The drainage process 100 is constantly kept open. An inlet part 1 is embedded in the bottom opening 4 and rests with its Flanschkranz 2 on the widened upper edge of a pipe socket 3, in which an odor trap 40 and a side drain pipe (not shown) are located. The located below the bottom opening 4 part of the drainage flow 100 does not form part of the invention and can therefore be designed differently.

Above the flange ring 2, a cover element 5 is inserted into the stepped bottom opening 4. In the present case, the cover element is designed in the form of a round disc and provided with a flange edge 5.1. However, it is also possible to make such a cover element as a rust, the edge runs out flat. In both cases, there is a "level opening" 6, can flow into the water and run down.

Also, oval, rectangular or polygonal cover element arrangements can be provided in a corresponding manner with an adjusting device described below.

With the top of the Flanschkranzes 2 of the inlet part 1 four adjusting 7.1, 7.2, 7.3 and 7.4 are connected, with which the lid member 5 is height adjustable relative to the flange ring 2. As in the sectional drawing according to FIG. 4 shown, a plurality of position bolts 8 are mounted towering on a flange 2, for example, by welding or gluing. The position bolts 8 are made of brass or other corrosion-resistant materials and are designed to taper upwards; on the outside they are smooth.

The opposite bottom 5.2 of the cover element 5 is provided with four threaded sleeves 9, which have an internal thread 9.1. The threaded sleeve 9 has a height of h1. In the internal thread 9.1 of the threaded sleeve 9, a threaded sleeve 10 with external thread 10.2 and internal cavity 10.1 is screwed with part of its length. The threaded sleeve 10 has a length of I1> = h1 and thus surmounted the threaded sleeve 9 down even when partially turned. The inner cavity 10.1 of the partially screwed threaded sleeve 10 is pushed over a positioning bolt 8 until the lower edge of the threaded sleeve 10 abuts the flange ring 2. Thus, the height of the lid member 5 is fixed relative to the inlet part 1. In order to lock the position of the threaded sleeve 10 relative to the threaded sleeve 9, a nut 11 can additionally be turned onto the threaded sleeve 10. Preferably, nuts with a fixing property are selected for this purpose.

The cover element 5 can be lifted out of the bottom opening 4 as required, in particular for cleaning the drainage process. Also a readjustment of the height is easily possible. The lifting of the cover element is facilitated because tilting against the position pin 8 is prevented by their design.

In the FIGS. 3a to 3c is schematized the detail C according to Fig. 1 shown in different height adjustments. With the use of threaded sleeves 10, in particular those with different lengths, several height and distance ranges between cover element 5 and inlet part 1 can be adjusted. The adjustment is possible continuously.

FIG. 3a shows that the threaded sleeve 9 can be pushed with fully screwed threaded sleeve on the position pin 8. This applies, for example, at a standard distance from flange 2 to bottom 5.1 of, for example, 15 mm. In the embodiment according to FIG. 3b is screwed a threaded sleeve 10 with a length of 14 mm, so that here a total distance range of about 15 to 25 mm is covered.

If instead of the threaded sleeve with the length of 14 mm one of 22 mm is used ( Figure 3c ), this results in a range of 25 to 37 mm for the adjustment.

Here, depending on requirements, other threaded sleeves or even those with different dimensions can be selected.

Overall, there is a good opportunity to use according to the floor and drain structure different heights of the cover member relative to the inlet part. In this case, the solution according to the invention can be used both in round and in elongated, channel-shaped Endwässerungsabläufen.
