Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a male form for a water connection between a flexible irrigation hose and the outlet of a domestic faucet unit provided with a flat top and a vertically oriented water supply. The present invention relates to a coupling member.

[0002]

2. Description of the Prior Art Devices for connecting the water supply between a flexible irrigation hose and a water outlet are known and are composed of two separate, connectable coupling members.
A first or female coupling member is connected to the irrigation hose and a second or male coupling member is connected to the outlet. The connection between the two coupling members is made by a variety of techniques that typically use snap-fit connection means.

A feature of the known device for connecting the irrigation hose to the water outlet is largely dependent on the shape of the water outlet, and the connection to the water outlet is made especially with respect to the male coupling member.

A female coupling member, which is generally of a standard shape, is formed of a generally hollow cylindrical plastic structure, one end of this structure is provided with means for connecting and fixing a rubber hose, and the other end is a male cup. Means for connecting the ring members are respectively provided.

The shape and size of the male coupling member, on the one hand, depends largely on the particular shape of the outlet to which the irrigation hose is to be connected.

Very often, the water outlet is constituted by a hollow metal arm whose end is a water inlet having a male screw portion. In this case, the male coupling member is composed of a plastic ring having a female threaded portion, which is threadedly connected to a water supply port having a male threaded portion and provided with a tongue drilled downward. The tongue is provided with a seal and is externally shaped for snap-fit connection with the female coupling member.

If the water outlet is not provided with a screw portion for the end water supply port, the connection with the water outlet is surely made by the annular male coupling member. In this case, the annular male coupling member is placed outside the outlet. And then fix it with an external ring nut. In this case as well, the male coupling member is likewise provided with a drilled tongue on its underside, which is provided with a seal and which forms an external shape which can be snap-fitted into the female coupling member.

[0008] Finally, the mixer of the domestic faucet unit for the ceramic washbasin and washbasin, in particular the mixer of the domestic faucet unit, is fixed at one end to the ceramic part of the washbasin and the water supply port of the mixer is provided. Consideration should be given to the case of a hollow metal arm that is curved so as to orient vertically.

In this type of water outlet, the male coupling member is composed of a hollow cylindrical support casing having a wide lateral hole defining a space for accommodating the end of the metal arm of the mixer. Is known. The lower base of the cylindrical casing has a vertical tongue that is drilled and an annular seal is provided on the tongue for placement at the mixer outlet. On the other hand, the upper base is provided with a clamping means constituted by a screw-in cover, and the movement of the screw-in cover determines the change in the height of the space for accommodating the arm of the faucet unit.

The male coupling member can be fixed to the arm by inserting the end of the arm of the faucet unit into the accommodation space and aligning the water inlet of the faucet unit with the above-mentioned annular seal. This fixing is done by manipulating the screw-in cover until a sufficient reduction of the height of the accommodation space mentioned above is obtained. The connection with the female coupling member is ensured by the presence of a vertical tongue which is drilled and the external shape of this tongue is chosen to allow a snap-fit connection of a conventional female coupling member.

[0011]

The main drawback of the above-mentioned prior art is that when screw-blocking a male coupling member to a faucet unit it is often not possible to guarantee a complete fixing of the connecting member. , Especially for long irrigation times, inevitably has an adverse effect on the hydraulic seal of the connection between the water inlet of the faucet unit and the internal seal of the connecting member.

An object of the present invention is to provide a flexible irrigation hose,
A male coupling member for the water supply connection between the outlet of a domestic faucet unit with a flat top and a vertically oriented water supply, which provides a reliable clamping system and consequently a complete hydraulic seal. It is an object of the present invention to provide a male coupling member that is provided and at the same time has sufficient versatility to be applicable to faucet units of various sizes.

[0013]

SUMMARY OF THE INVENTION According to the present invention, for the purposes set forth above, a transverse hole is defined for defining a space for accommodating the flat end of the outlet of a faucet unit provided with a vertical water inlet. A support casing having a lower end, the lower end being a drilled vertical tongue providing an annular seal for connecting the male coupling member to the female coupling member, and the upper end being the protruding end. In a male coupling member that serves as a pressure clamping means for clamping the support casing under pressure against the end of the water opening, the drilled tongue is constituted by a structure screw-connected to the support casing, This is achieved by the fact that the clamping means is constituted by an eccentric drum which is rotatable around an axis which is orthogonal to the axis symmetrical to said tongue.

It is clear that in this way it is possible to obtain a male coupling member for the water supply connection between the irrigation hose and the domestic faucet unit, in particular the outlet of the mixer of the male coupling member. This male coupling member has the advantage that it ensures a completely mechanical and hydraulic seal and, due to the adjusting ability of the screw-in assembly, can be adapted to outlets of various sizes.
