Abstract

A wash stand comprises a hollow base (1) and a wash basin (2) secured on said base, a stand pipe (3) extending upwardly from the base and axially through an outlet aperture (8) feeding into a waste water collecting unit (14). The upper end of the base (1) comprises an inwardly directed wall portion (9) against the upper surface of which the wash basin (2) bears, while the waste water collecting recess (14) abuts the lower surface of the wall portion (9) and is screwed to the stand pipe (3). An element (18) bridging the outlet aperture of the basin (2) is fitted axially over the stand pipe (3) and bears against the inner side of the basin, a screwthreaded unit (12) on a correspondingly threaded extent (10) of the stand pipe (13) serving to clamp the element (18), the basin (2) and the wall portion (9) between said nut (12) and the waste water collecting unit (14). <IMAGE>

Description

SPECIFICATION Wash stand The present invention relates to a wash fountain or stand.

It is known to provide wash stands which include a hollow base from which a riser or stand pipe extends upwardly and a wash basin which is secured on the base and axially through the outlet aperture of which the stand pipe extends, a waste water collecting unit being arranged after the outlet aperture.

In a wash stand of this kind the basin is fixed to the base by a plurality of screws arranged symmetrically about the axis of the base, a corresponding plurality of lugs being provided on the underside of the wash basin. The outlay involved in the manufacture and assembly of such a wash stand is considerable.

It would be desirable to provide a wash stand of the aforesaid type in which the manufacture and assembly of the parts is simpler.

According to the present invention there is provided a wash stand comprising a hollow base including, at its upper end, an inwardly directed, annular wall portion, and a basin supported on said wall portion and having an outlet aperture in the lower regions thereof, a stand pipe extending upwardly from the hollow base axially through said outlet aperture in the basin, the wash stand further comprising a waste water collecting unit into which the outlet aperture of the basin feeds, said unit abutting the lower surface of the wall portion of the base and being secured to the stand pipe, and an element within the basin and fitted around the stand pipe to bridge the outlet from the basin, said element bearing against the inner surface of the basin, a screwthreaded nut on a correspondingly threaded portion of the stand pipe serving to clamp the element, the basin and the wall portion of the base between said nut and the waste water collecting unit.

Preferably the wash stand includes sealing rings reacting between the underside of the basin and the wall portion of the base and between the waste water collecting unit and the wall portion of the base.

Conveniently, the waste water collecting unit has a central, axial, screwthreaded bore formed therein, the stand pipe having a coresponding external thread formed on its lower end which is recieved into said bore in said unit.

In a preferred wash stand the lower end of the screwthreaded bore in the waste water collecting unit is defined by an annular rib, a sealing ring being clamped between said rib and the lower end face of the stand pipe.

By way of example only, an embodiment of the invention will now be described in greater detail with reference to the accompanying drawings of which: Figure 1 is side view of wash stand according to the invention with one half shown as a vertical section, and Figure 2 shows a detail from figure 1 on a larger scale.

Referring to the drawings, reference numerals 1 and 2 designate a base and a wash basin respectively. The base 1 is hollow and is preferably constructed as a self-supporting moulded part of, for example, synthetic plastic material reinforced with glass fibre.

The wash basin 2, which can be a deep-drawn or pressed sheet metal basin or moulded from glass fibre reinforced synthetic plastic material, rests on the base 1. A stand pipe 3 projects upwardly from the base 1 centrally of the wash basin 2, and has a plurality of outlets 4 at its upper end situated in radiating formation about a distributor 16, as well as a soap dish 5. The outlets 4 are each adapted to be operated by a servo-controlled diaphragm valve 6 which can be actuated by an associated pneumatic pedal 7. Alternatively, the outlets 4 may be normal discharge valves, in which case the valves 6 and the pedals 7 are dispensed with.

A central outlet aperture 8 of frusto-conical shape is provided in the lower regions of the wash basin 2, said outlet aperture 8 bearing on a correspondingly inwardly directed wall portion 9 of the base 1. The lower end of the stand pipe 3, in the region of the outlet aperture 8, is formed with an upper external screwthread 10 and a lower external screwthread 11.

A nut 12 is screwed over the upper screwthread 10, while the lower screwthread 11 is screwed into a screwthreaded bore 13 in a waste water collecting unit 14.

A riser supply conduit 15 extends through the screwthreaded bore 13 into the stand pipe 3 as far as the distributor 16. The waste water collecting unit 14 has a flange-like edge 17 which bears against the underside of the inwardly directed wall portion 9 of the base 1. Beween the nut 12 and the outlet aperture 8 of the basin 2 there is fitted, axially on to the stand pipe 3, an element 18 in the form of a plate which bears against the inside surface of the wash basin 2 and is provided, around its outer edge, with perforations 19 for the outflow of water.Tightening of the nut 12 results in the element 18, the wash basin 2 and the wall portion 9 of the base 1 being clamped between the nut 12 on the one hand and the waste water collecting unit 14 on the other hand, so that the base 1, the wash basin 2, the stand pipe 3 and the waste water collecting unit 14 form a rigid unit.

A groove 20 is formed in the upper surface of the flange-like egde 17 of the unit 14, said groove 20 receiving an annular sealing element 21. Similarly a groove 22 is formed in the upper surface of the wall portion 9 ofthe base 1, an annular sealing element 23 being positioned in said groove 22. The elasticaliy compressible annular sealing elements 21 and 23 not only prevent water overflowing from the waste water collecting unit 14when the outlet from said unit is blocked, but also compensate for dimensional tolerances in the manufacture of the base and the wash basin 2.

The lower end of the screwthreaded bore 13 is determined by an annular rib 24. A sealing ring is inserted between said rib 24 and the lower end face of the stand pipe 3. The procedure for assembling the wash stand is as follows. The nut 12 is screwed onto the upper screwthread 10 of the stand pipe 3 and the element 18 is placed axially over the lower end of said stand pipe 3. The stand pipe 3 is then located from above into the outlet aperture 8 of the wash basin 2 and the waste water collecting unit 14 is introduced through an opening 25 into the base 1 and is screwed from below onto the lower screwthread 11 until the annular sealing element situated on the annular rib 24 is securely clamped. Then the nut 12 is tightened from above until base 1 and basin 2 form a rigid unit. In the now free-standing wash stand, the pneumatic conduits which extend downwards from the valves 6 through the stand pipe 3 can be connected to the push buttons 7 and to the water supply and discharge piping.

Claims
