Cover plate element and its counterpart Täckplattelement och motstycke till detta

The invention relates to a cover plate element for use in connection with a water or sewer pipe, in which an opening is formed for guiding the pipe or an associated part through the cover plate element, which cover plate element is cup-shaped so as to include a cover lid part and a wall part or to guide an associated portion through the cover portion.

In the case of water and sewer pipe bushings, a cover plate has not usually been used, because the bushings are often located so close to the wall that no cover plate fits in such a place.

The corner pieces used to connect the pipes are also usually left without a cover plate due to mounting difficulties. Of course, piping can also be installed inside a wall, but it is not always possible.

15 In this case, the bushings and fittings remain ugly unprotected.

A cup-shaped cover plate element with an opening formed in the cover part is disclosed in HVAC accessories catalog, second edition, 1977, HVAC tie-20 tokeskus r.y. Helsinki, page 332, supply numbers 8210 and 8220.

The object of the present invention is to provide a new type of cover plate element for use in connection with water or sewer pipes. The invention is characterized in that the opening is arranged eccentrically in the cover part, and that a locking member, such as a rim or groove, is formed in connection with the opening of the cover part, by means of which the cover plate element can be locked in place.

The invention also relates to a mating piece for use in conjunction with the cover plate element 30 described above, such as a corner piece of a water or sewer pipe. The mating piece according to the invention is characterized in that a locking response, such as a rim or a groove, is formed in the mating piece, into which the locking member of the cover plate element can be locked by pressing.

Fig. 8 corresponds to Fig. 5 and shows a third embodiment of the cover plate element.

Fig. 9 corresponds to Fig. 5 and shows a fourth embodiment of the cover plate element.

Figure 1 shows a prior art installation method in which the sewer pipe 1 coming from the washing machine 11 is led into the wall 12 by means of a corner piece 5. Inside the wall, the drain is formed by a pipe 2 which is further led into the floor 13. This type of installation is expensive and difficult to do. In particular, embedding a sewer pipe in a concrete wall is laborious. For this reason, pipe installations are often made as a surface installation, in which case, in the case shown in Figure 1, the pipes 1 and 2 and the corner piece 5 remain exposed unprotected.

Figure 2 shows a corresponding sewer installation according to the invention. The sewer pipe 1 coming from the washing machine 11 is led to a corner piece 5 mounted on the surface 35 3 73280 of the wall 12, which is covered by a cover plate element 3 according to the invention. This cover plate element 3a 5 is similar in other respects to the upper cover plate element 3 except that there is no opening in the side wall 7 of the element 3a. After all, there must be an opening in the side wall of the element 3 for the drain pipe 2. The installation of the sewer pipe shown in Figure 2 is well protected, but still considerably cheaper than that shown in Figure 1.

Figure 3 shows an axonometric view of the mounting method of Figure 2. Although the wall-oriented drain pipe 2 is visible, the installation is well protected due to the cover plate elements 3 according to the invention.

Figures 4 and 5 show compatible mating pieces 5 and a cover plate element 3 to be connected thereto. The mating piece is formed by an angle piece 5 fixed to the wall by a flange 14. A threaded opening 15 enters a threaded pipe, e.g. from a washing machine. in 20 leading sewer pipe. A rim 9 is formed in the corner piece, by means of which the cover plate element can be locked to the corner piece.

The cover plate element of Fig. 5 is placed on the corner piece of Fig. 4 so that the opening 4 in its cover part 6 comes on top of the opening 15 of the corner piece 5. By pressing the cover plate 3 against the corner piece 5, the groove 8 in the opening 4 of the cover plate element locks into the edge 9 of the corner piece. The drain pipe is led down to the floor through the opening 10 in the wall part 7 of the cover plate element.

Figure 6 shows a cover plate element 3 according to the invention locked to a corner piece 5. A groove 8 at the edge of the opening in the cover part 6 of the cover plate element 3 is locked in the edge of the corner piece 5. The cover plate element is preferably plastic or other flexible . A drain pipe from a washing machine can then be led into the opening 15 of the corner piece 5, which is fastened with a thread 17. Correspondingly, a drain pipe going under the floor is placed in the opening 16 provided with a seal 18 of the corner piece 5.

Figures 7, 8 and 9 show cover plate elements corresponding to Figure 5, the shape of which is adapted to correspond to different installation objects. It should be noted that all these elements, as well as in Fig. 5, have an opening 10 in the side wall. However, according to a known manufacturing method, the cover plate element 3 can be easily arranged so that the intact side wall 7 is replaced by the opening 10, for example by thinning the wall. In this case, it is easy to open the opening at this point if necessary.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the claims set forth below. Essential to the invention is an eccentric cover plate element 15 which can be locked by pressing, which is suitable, for example, for protecting a corner piece according to the invention with a locking stop. However, this cover plate element can also be used in places where there is no locking response according to the invention. Such an installation example is the protection of the passage of the drain pipe 2 20 to the floor 13 shown in Figures 2 and 3 by a cover plate 3. The eccentricity of the cover plate 3 allows the pipe 2 to be installed very close to the wall 12.
