Description

  • The present invention relates to a draining device for sanitary fittings, such as sinks and the like.
  • As is known, sinks are conventionally provided with a draining system comprising a drain element mounted in a hole on the bottom of the sink, and an overflow arrangement.
  • The aim of the present invention is to provide an adjustable draining device to be applied to sinks of any desired size.
  • Within the scope of the above mentioned aim, a main object of the invention is to provide such an adjustable draining device for different thickness and different horizontal and height sinks.
  • Another object of the present invention is to provide such a draining device including a built-in overflowing system.
  • Yet another object of the present invention is to provide such a draining device which, owing to its specifically designed features, is very reliable and safe in operation.
  • According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a draining device for sanitary fittings as a sink, characterized in that said draining device comprises a drain element mounted in an underdrain element.
  • Said drain element comprises a top flange abutting against a top surface of the sink bottom.
  • Said underdrain element comprises a bottom flange abutting against a bottom surface of the sink bottom.
  • A screw member connects the drain element to the underdrain element and engaging therewithin a stem of a closure plug.
  • Said underdrain element is coupled to an overflowing system operating based on a communicating-vessel principle.
  • Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of the invention, which is illustrated, by way of an indicative, but not limitative, example, in the accompanying drawings, where:
    • Fig. 1
    is an exploded perspective view showing the main components of the draining device according to the present invention;
    Fig. 2
    is a side elevation view, as cross-sectioned, showing the subject device in an open-plug condition thereof;
    Fig. 3
    is a view similar to Figure 2, showing the subject device in a closed-plug condition thereof;
    Fig. 4
    is a view similar to Figure 3, showing the device in its closed-plug condition, as the sink is filled-in by water; and
    Fig. 5
    is a view similar to Figure 4, showing the water outflow through the overflowing system.
  • With reference to the number references of the above mentioned figures, the draining device for sanitary fittings such as sinks and the like, according to the present invention, generally indicated by the reference number 1, comprises a drain element 2 mounted in an underdrain element 3 through an interposition of a sealing O-ring 4.
  • The draining element 2 comprises a top flange 5, abutting against a top surface 6 of the bottom of the sink 7.
  • The underdrain element 3 comprises, in turn, a bottom flange 8 abutting against a undersurface 9 of the bottom of the sink 7, through an interposition of a sealing gasket 10.
  • A screw member 11 connects of clamps the drain element 2 to the underdrain element 3 and engages therein the stem 12 of a closure plug 13, through an interposition of a further sealing O-ring 14.
  • The plug element 13 comprises a plug disc 15, including a respective O-ring 16, sealing said drain element 2, and a top bowl 17 including radially extending openings.
  • The underdrain element 3 comprises two radially extending outlets, a top outlet 18 and a bottom outlet 19.
  • Said top outlet 18 is coupled to a top elbow 20, and said bottom outlet 19 is coupled to a bottom elbow 21, through respective sealing gaskets 22 and 23.
  • Said top elbow 20 is coupled to an overflow tube 24, whereas said bottom elbow 21 is coupled to an outflow tube 25, through respective coupling sealing gaskets 26 and 27.
  • Said overflow tube 24 is further coupled to said outflow tube 25 by a top fitting 28, said overflow tube 24 comprising, above said top fitting 28, an opening 29 closed by a casing 30.
  • The thus made overflow system operates based on the communicating-vessel principle as it will be disclosed in a more detailed manner hereinafter.
  • According to the present invention, said underdrain element 3 has an adjustable height and may be used with different thickness sinks, thereby always providing a sealing tightness between the drain and underdrain elements.
  • The adjustment of the draining device, based on the width and height of the sink, is carried out by properly designing to a set size the elbows 20, 21 and related tubes 24, 25 respectively.
  • Advantageously, the above components, as well as the underdrain element, are made of a plastics material.
  • Thus, independently from the adjustment of the drain with respect to its underdrain, that is for any desired thickness of the sink, from a minimum to a maximum one, the configuration of the drain will always allow, with the plug being opened, to fully empty the tube 20, as is shown in Figure 2.
  • Figure 3 shows the plug in a closed position, in which the disc 15 shuts off the water flow thereby preventing water from arriving at the underdrain bottom 31.
  • With the plug being in a closed condition, the radially extending opening of the top bowl 17 allows water to flow into the top elbow 20 of the overflowing system, as is shown in Figure 4.
  • As the sink is filled-in by water, said water is continuously raised through the overflowing system 24, thereby the sink water level will exceed the top fitting 28 level.
  • At this time, water will overflow from the overflowing tube 24, through the top fitting 28 into the outflow tube 25 and the bottom elbow 21 to be drained into the underdrain bottom 31 and outlet tube, as is shown in Figure 5.
  • It has been found that the invention fully achieves the intended aim and objects.
  • In fact, the invention has provided a draining device with a built-in overflowing system which may be easily applied to sinks of different size.
  • The drain side elongated holes or slots are always arranged under the overflowing tube thereby providing an optimum overflowing tube draining.
  • A further embodiment provides a draining device, for sanitary fittings such as a sink, wherein said draining device may comprise a drain element mounted in an underdrain element; said drain element may have a top flange abutting against a top surface of a sink bottom; said underdrain element may have a bottom flange abutting against a bottom surface of the sink bottom; a screw member' may couple the drain element to the underdrain element and may engage therewithin a stem of a closure plug; said underdrain element may be coupled to an overflowing system operating based on a communicating-vessel principle.
