Description

TUBULAR ELEMENT FOR CONNECTING THE OUTLET PIPE OF A SANITARY APPLIANCE TO A DRAIN OUTLET OR A WALL FITTING

The subject of the present innovation is a tubular element according to the generic term of the present innovation. In the present description, the term sanitary facilities is to be understood in particular as meaning wall-mounted ceramic toilet bowls in which the ceramic water outlet pipe is connected to a wall socket which is set into the wall to which the toilet bowl is attached.

In order to connect the toilet bowl to the wall socket, it is known to use both pipes and hoses.

If the toilet bowl outlet pipes and the wall socket are not aligned, the pipes must be bent accordingly, a disadvantage that can be avoided by using hoses that must, in any case, be cut to fit the toilet bowl to the wall socket in the best possible way. In both cases, connecting sleeves must also be attached to the ends of the pipes or hoses to connect them to the toilet bowl outlet pipe and to the wall socket. This work must be carried out with extreme care, as any leakage of liquid or gas must be avoided at all costs.

It must also be noted that both the toilet bowl outlet pipe and the wall socket can have different diameters (typically 0.08-0.11 m and 0.09-0.11 m respectively). If the known connection elements are used, a large number of sockets with different diameters must be available.

The aim of this innovation is to create a connecting element for the connection of hygiene facilities to a drain pipe or a wall socket, which can be deformed three-dimensionally and remains in the position it is in at any given time and can be adapted to the outflow pipes of the hygiene facility and drain pipes of different diameters, so that the connection work of the toilet bowl to the drain can be carried out faster, easier and simpler.

Another aim of the innovation is to create a connection element that ensures perfect sealing against both liquids and gases.

Another goal is to create a cheap and easy-to-manufacture connection element.

For a better understanding of the present innovation, drawings are attached for illustrative purposes and without limitation, in which

Figure 1 shows a perspective schematic view of a partially deformed connecting element according to the innovation;

Figure 2 shows a schematic perspective view of one of its ends;

Figure 3 shows a schematic enlarged sectional view of the other end thereof;

Figures 4 and 5 show schematic enlarged views in section of two central sections thereof in two different positions of use.

With reference to the drawing figures, a connecting element according to the innovation has a central part 1 which is three-dimensionally deformable and can remain in a position once it has been assumed and can be returned to the original position, wherein in the area of its ends it has two connecting parts 2 and 3 for connection to the outlet pipe of a toilet bowl and a wall socket (not shown).

The middle part 1 is of a known design and can be stretched axially (Figure 4) or compressed axially (Figure 5) or bent (Figure 1) completely or only partially, so that the connecting parts can be brought into the desired angle and position.

In the axially extended state (Figure 4), the central part 1 has a series of ring-shaped elevations 9, which are interrupted by depressions 9A. The elevations 9 are formed by two opposing frustoconical surfaces Λ,β. The two surfaces Λ,β of each elevation have a different conicity and height H1 and H2 in relation to the larger ring base sections 11 and smaller ring base sections 1IA (Figure 4). If the connecting element is viewed from the side, all elevations on one side have the same conicity.

As shown in Figures 4 and 5, the surface 1OB of the elevations of the connecting element, during the transition from an extended position (Figure 4) to a compressed position (Figure 3), passes from a first position in which the surface runs obliquely with respect to the surface 1OA to a second position in which the said surfaces run parallel to one another and essentially touch one another.

It should be noted that the transition from one position to the other entails an elastic deformation of the surface 1OB and that both positions correspond to a stable equilibrium or the elevations of the connecting element remain in the position into which they were brought.

The connecting element according to the innovation can be bent not only two-dimensionally, but also three-dimensionally (see for example in Figure 1). When the connecting element is bent, a part of the surface 1OB of one or more elevations runs essentially parallel to the adjacent surface 10A, whereas the other part runs obliquely with respect to the surface 1OA, the two parts having an opposite concavity.

This deformation of the connecting element is also possible thanks to the elasticity and deformability of the material from which the element is made. This elasticity and deformability also enable the connecting element to remain stable in the deformed position into which the element was brought from case to case.

The connecting element can easily be returned to its original, essentially cylindrical position with the projections pressed together (Figure 5), without risking the element breaking.

Preferably, the central part has an outer diameter of 0.13 m.

The central part is made by pressing any known, essentially elastic and deformable plastic material, preferably polypropylene. Since the element is made of plastic, it is easily recyclable and since it has no metal parts, it is not subject to corrosion.

The middle part has a cylindrical section in the area of one of its ends without annular elevations and has, preferably along its outer surface, a groove (not shown) which promotes the adhesion of the connecting part 2 to the surface.

The connecting part 2 has an elastic wall 4 with a central hole 6 and an annular side wall 7 which can come to rest on the grooved surface of the cylindrical section 5. The connecting part 2 consists of any known plastic material which can be pressed onto the cylindrical section 5.

Since the connecting part 2 is pressed onto the cylindrical section 5, it forms a single part with it and thus ensures the best sealing properties.

The hole 6 has a diameter of less than 0.08 m, preferably 0.07 m. The outlet pipes of the toilet bowl have variable diameters between 0.08 and 0.11 m and thanks to the dimensions of the hole 6 and the elasticity of the wall 4, all these pipes can be inserted into the hole 6 in a sealed manner.

In order to further stiffen the end part of the connecting element, a ring 8 made of essentially rigid material is provided in the area of the connecting part 2, which ring 8 lies above the ring wall 7.

In the area of the other end, the central part 1 has a second cylindrical section 12 which has a smaller outer diameter than that of the part 1 and has a grooved outer surface which promotes the adhesion of the connecting part 3 to the surface.

The connecting part 3 is designed in the manner of a ribbed seal and has a ring 13 from which three rows of ribs 14, 15, 16 with different

outside diameters, whereby both the ribs and the ring are made of any known elastic plastic that can be pressed onto the cylindrical section 12. Thanks to the ribs 14-16, the connecting part 3 can be inserted in a sealing manner into wall sockets with different diameters. Preferably, the ribs 14-16 have outside diameters of a little more than 0.09, 0.1, 0.11 m, so that the part 3 can be inserted in a sealing manner into wall sockets with the above-mentioned dimensions.

Thanks to the pressing of the connecting part 3 onto the cylindrical section 12, this part and this section form a one-piece construction and ensure a perfect seal.

It should be noted that by using a connecting pipe according to the innovation, the time required for the work to connect the toilet bowl to the wall socket is far less than with the known connecting pipes.

Furthermore, since a connecting pipe can be obtained completely with the connecting end parts by pressing according to the innovation, the production costs of the connecting pipe are also lower than for known pipes.
