Abstract

Connection joint (1) for sanitary appliances that is placed in an outlet sleeve (6) of a sanitary appliance which is inserted into a drainage channel (5), characterized in that it comprises two parts (2, 3), a first part (2) of larger diameter, and a second part (3) of smaller diameter, wherein the transition of the first part (2) to the second part (3) is carried out through a transition area (4), including a weakening line (8) that allows the separation of the first part (2) and the second part (3); the two parts (2) comprise a cylindrical central body (10) and radial fins (7) located around the central body (10), of a diameter larger than the drainage channel (5) wherein the sleeve (6) is inserted with the connection joint (1) installed.

Description

OBJECT OF THE INVENTION

The present invention is related to a joint that can be adapted to two diameters of a drainage channel to which the sanitary element is connected through an elbow incorporated in the sanitary element.
Based on this objective, the new joint of the invention is intended to facilitate the connection of the sanitary elements with the drainage channels, and the connection can be adapted to two different diameters through the same joint that allows the connection with one diameter or with another diameter interchangeably.

BACKGROUND OF THE INVENTION

Currently, the joints used in the connection of the toilets to the drainage channels, are adapted to a single diameter of a drainage channel, and, according to the aforementioned diameter of the drainage channel existing in the site installation already done, a joint with a diameter or a joint with another diameter is used. This diversity of diameters implies, for the assembler, the need for having different joints for using the joint with the appropriate diameter according to the features of the installation that will be executed.
The object of the invention, which proposes a single joint that adapts to two different diameters, thus reducing the number of parts that the assemblers must have available for performing their work, arises to reduce the need for multiple joints, with the problem for the assembler of the availability and the transport of different joints for the connection of the toilets to the installations of different diameters.
Different joints for the connection of sanitary appliances are known in the state of the art. Document US 2005073148 A1 discloses a pipe connection element comprising threaded elements that provide the connection. Also the state of the art shows document U 150781 that discloses a watertight joint for toilet drains.

DESCRIPTION OF THE INVENTION

In order to avoid the drawbacks indicated above and achieving the objectives mentioned above, the invention consists of a joint to be placed on the drain of the sanitary appliances, which can be attached to two diameters of drainage channel.
The sanitary appliances connection joint is placed in a sleeve outlet of a sanitary appliance which is inserted into a drainage channel comprising two parts: a first part of larger diameter, and a second part of smaller diameter. The passage from the first part to the second part is carried out through a transition area, including a weakening line that allows the separation of the first part and the second part.
Both the first part and the second part of the connection joint object of the invention comprise a central body and radial fins located around the central body of the connection joint, of a diameter larger than the drainage channel wherein it is inserted such that it ensures the connection and the sealing in the connection of the sanitary appliance with the drainage channel.
The sanitary appliances connection joint object of the invention is made of elastomer material.

DESCRIPTION OF A PREFERRED EMBODIMENT

The invention is intended to make easier the connection of sanitary appliances with one single joint that enables the connection of the output of the sanitary appliance to the different dimensions of the drainage channels in which the toilet is installed.
Figure 1 shows the connection joint (1) installed in a sleeve (6) conventionally used for the connection of the sanitary appliance to a drainage channel (5).
Figure 2, wherein an elevational view of the installation of figure 1 is shown, shows the connection joint object of this invention.
The connection joint (1) object of the invention comprises two cylindrical parts, a first part (2) of a diameter and a second part (3) of a diameter smaller than the diameter of the first part (2). The connection joint (1) is placed around the sleeve (6) used for the outlet of the sanitary appliance. The sleeve (6) is inserted inside the drainage channel (5). The first part (2) as much as the second part (3) of the connection joint (1) comprise a cylindrical central body (10) and radial fins (7).
The radial fins (7) are placed around the central body (10). The fins (7) are elastic and have a diameter larger than the diameter of the drainage channel (5) in which the outlet sleeve (6) is inserted with the connection joint (1) placed around the sleeve (6), such that the watertightness in the junction of the sleeve (6) and the drainage channel is ensured (5).
The first part (2) of the connection joint (1) is connected to the second part (3) through a transition area (4), in which the change from the larger diameter to the smaller diameter occurs. The transition area (4) comprises a weakening line (8) through which the first part (2) is detached from the second part (3), so that two independent parts with different diameter are obtained.
In the preferred embodiment of the invention the weakening line (8) comprises drillings (9) along the line, allowing quick and simple separation of the two parts (2, 3) of the connection joint (1).

Claims

Connection joint (1) for sanitary appliances which is placed in an outlet sleeve (6) of a sanitary appliance which is inserted into a drainage channel (5), characterized in that it comprises two parts (2, 3):
- a first part (2) of larger diameter,

- a second part (3) of smaller diameter,
wherein the transition of the first part (2) to the second part (3) is carried out through a transition area (4), including a weakening line (8) that allows the separation of the first part (2) and the second part (3).
Connection joint (1) for sanitary appliances, according to claim 1, characterized in that the first part (2) as much as and the second part (3) comprise a cylindrical central body (10) and radial fins (7) located around the central body (10) of the connection joint (1), of a diameter larger than the drainage channel (5) wherein the sleeve (6) is inserted with the connection joint (1) installed, such that it ensures the connection and the watertightness in the connection of the sanitary appliance with the drainage channel (5).
Connection joint (1) for sanitary appliances, according to previous claims, characterized in that it is made of elastomer material.
