Drainage fittings for sinks

The utility model relates to domestic sanitary devices and relates, in particular, to drainage fittings for sinks.

The closest technical solution adopted for the prototype is a drainage fitting for sinks containing an outlet connected to the outlet through an overflow corrugated pipe overflow with a central hole for the fastener, and a gasket, the shape of which coincides with the shape of the overflow inlet, with flat surfaces for sealing overflow with overflow hole of the sink (Patent EP No. 0537896, class E 03 C 1 / 20,1995).

The objective of the utility model is to expand the functionality of the device, increasing its reliability and ease of use.

The problem is solved due to the fact that the drainage fittings for sinks containing an outlet connected to the outlet through an overflow corrugated pipe overflow with a Central hole for the fastener, and a gasket, the shape of which coincides with the shape of the inlet overflow, with flat surfaces for sealing overflow with overflow the sink hole is provided with an additional gasket, one of the surfaces of which, designed to contact the outer surface of the sink, is made spherical, and the overflow housing consists of two parts Tay: rectangular, intended for contact with the cylindrical sink and connected to the overflow pipe. The axis of the overflow outlet may be perpendicular to the axis of its inlet or aligned therewith.

In FIG. 1 shows a General view of the reinforcement; in FIG. 2-embodiment overflow with coaxial holes.

The spillway fitting includes a corrugated pipe 1 with a gasket 2 and a nut 3 for connecting to the drain and overflow 4. The overflow is attached to the sink using a screw 5. The junction of the overflow to the sink is sealed with gaskets 6 and / or 7. The gasket 6 is made with flat surfaces, and gasket 7 with one spherical surface, which allows the use of a set of spillway fittings for sinks of various shapes. Overflow 4 can be performed in two types: with perpendicular inlet and outlet openings

(Fig. 1) and with coaxial holes (Fig. 2), which allows the use of fittings for sinks with a different arrangement of overflow holes.

To install the fittings on the sink of the sink, screw 5 is inserted into the socket of the grate of the overflow hole and, with its help, overflow 4 is tightly drawn with the gasket installed to the sink. Depending on the shape of the sink, different gaskets and different overflows can be used, which simplifies installation and increases the reliability of the device. The second end of the corrugated pipe is attached to the nozzle of the drain bell or siphon using a nut 3.

The proposed design of spillway fittings can be implemented industrially using well-known technical means, technologies, materials and components and meets the requirements of the criterion of industrial applicability.

The described design is simple, reliable, easy to use and has an attractive appearance.
