Closure for the drain opening of a tub, a wash basin, a washing up or the like.

The innovation concerns a closure

for the drainage opening of a tub, a washbasin, a dish washing or the like. Such drainage openings are mostly rait a conical made of metal, rubber or plastic Plug closed, which is inserted into the central recess of a valve part having a plurality of holes at its bottom will. This valve part is fixed in the drain opening, e.g. of the wash basin, by means of a screw.

It always happens with such closures

again to the undesired drainage of the water because the plug is either too small or too large. It is, as a rubber stopper executed, dimensioned too large, it stays in the indented position

State in the valve part does not adhere and rises in height, whereupon the Wanser expires.

The aim of the innovation is to create a closure of the type mentioned at the outset, which is the desired one Leak tightness made possible with certainty. This is achieved according to the invention in that as a closing body with a sealing lip to lie on part of the valve edge provided disc is provided, the center of a sleeve-shaped, extending downward against the bottom of the valve part Has approach that engages over the screw head or a cylindrical approach extending upward from it and on this one! jftet.

When the closing body is put on, its

sleeve-shaped approach coupled to the valve part bottom, as it were, in that the shoulder adheres to the screw head or its extension. This causes the sealing lip to be pressed on of the closing body on the edge of the valve part, the sealing lip made of an elastic material easily deformed so that a completely tight seal of the drainage opening e.g. a wash basin is reached.

The screw head and the

cylindrical extension provided with two spaced apart annular grooves in which a bead-like reinforcement engages in the interior of the sleeve-shaped extension of the closing body and in the engagement position defines the closed or open position of the closure.

After one more thought, you become that

form the sleeve-shaped approach of the closure square in cross section and axially parallel, preferably in the corners of the i

Provide square incisions so that resilient webs are formed. j

An embodiment of the innovation according to the invention

Closure is explained in more detail below with reference to the drawing werien, in which Fig. 1 shows a longitudinal section of the closure. Fig. 2 is a section along the line A-B in Fig. Fig.? shows a view of the closing body from the side.

In the drawing, 1 with a drain opening 2, which is to be closed by means of a closing body S labeled washing. In the drain opening 2 of the waste

j Hasche is a valve part 3 with the interposition of a rubber

f seal '(! inserted by means of a screw 5. The valve part

ι usually consists of deep-drawn sheet metal and has at its Bc

ien 6 several holes 7 through which the water via a pipe socket 8 can expire. In principle, the valve part 3 with its bottom 6 is inserted into the drainage opening 2, e.g. of a basin Sieve, which is screwed with the screw 5 on the web 11 of the pipe socket $.

The closing body S itself consists of a disc made of elastic material, e.g. rubber, which at its circumference into a sealing lip 13 which tapers conically towards its edge expires. The closing body S is made in two parts and is provided with a handle 14, which in its lower area with a groove 15 is provided, into which the disc 12 is inserted and held by means of a ring 16.

Extends from the underside of the handle 14. A sleeve-shaped, slightly consicher approach 17 against the Valve base 6. In the interior of the projection 17, an annular bead is provided which is inserted into an annular groove formed on the screw head 19 intervenes. To form this annular groove 20, the screw head ΐ is provided with a cylindrical extension 21, which at its upper

Has a second annular groove 22 at the end.

■; The one from the underside of the handle 14 after

has the extension 17 extending below, as can be seen in FIG. 2,

j a square cross-section, being in the corners of the square

78018S8 05/03/78 ³

Slits 23 are provided which subdivide the approach 17 into v: he Ste ^ e 24. As can be seen from FIG. 1, the thickness of the webs 24 increases upwards towards the handle 14. Basically, the webs 24 represent four springs which, with the bead-like reinforcement 18, snap into the grooves 20 or 22 when they reach the area of one of these grooves by actuating the handle 14. Thus, the renewal according Verscnluß has two defined positions: In the upper position, in which the bead-like reinforcement 18 in the groove ?? engages, the closure is open and the disc S is lifted from the valve part 3 (open position). In the lower position, the bead-like reinforcement 18 engages in the groove 20, the sealing lip 13 being pressed against the edge of the valve part 3 (closed position).

In the open position there is sufficient

Gap between the sealing lip 13 and the edge of the valve part, with the advantage that you no longer need to attach the closing body to a chain in order to avoid losing it. the The sealing lip pressed in the closed position ensures a tight seal, with the lip engaging in the lower groove 20 Bead-like reinforcement 18 of the webs 24 ensures secure retention t.
