Definitions

  • the present invention relates to a device for opening and closing a plug for sanitary fittings as set forth in the preamble of claim 1.
  • Plugs for wash-basins, bath tubs, bidets and the like, comprising a mushroom element which can be driven from the outside by a lever system, are already known.
  • prior devices for operating prior plug elements are usually affected by the drawback that they require a perfect calibration and a continuous adjustment since, because of corrosion phenomena, scale deposits and mechanical clearances, they tend to not perfectly close the draining ducts.
  • GB-A 1 180 676 discloses a device having the features of the preamble of claim 1.
  • This known device comprises an end sleeve closing the lower end of an insert to which it is coupled by means of a bayonet coupling.
  • the upper edge of said sleeve is provided with teeth.
  • EP-A 288 731 relates to a drainage plug comprising a movable tubular portion, a tubular fixed portion and a rotary tubular portion.
  • a movable tubular portion When the rotary tubular portion is axially moved, the geometry of its contact sufaces causes a rotation of said portion.
  • a similar device is known from US-A 3 333 815 which is provided with a spring mechanism comprising a movable tubular portion, a tubular fixed portion and a rotary tubular portion.
  • a main object of the present invention is to provide such a device for opening and closing a plug for sanitary fittings which can be easily and quickly operated, and which does not require complex and antiaesthetic operating leverages.
  • Another object of the present invention is to provide such a device which can be easily applied to existing sanitary fittings.
  • Yet another object of the present invention is to provide such a plug operating device which does not practically require any maintenance operation, and is very safe and efficient in operation.
  • a device for opening and closing a plug for sanitary fittings which comprises a movable portion, adapted to be coupled to a plug element, and slidably engaged with a fixed portion, mounted an a drain associated with the outlet of the sanitary fitting, and rotary-translating means, operating against resilient means so as to allow said plug element to be switched from an open or raised position to a closed or lowered position, by pressing on said plug element
  • the device for opening and closing a plug for sanitary fittings comprises a movable portion 1, adapted to be coupled to a plug element, and slidably engaged with a fixed portion 2, adapted to be mounted on a drain of the sanitary fitting.
  • a rotary portion 3 including an axially extending hole, housing therein a coil spring 4, in turn engaged with a spring guide 5.
  • Figures 5 and 6 show an exemplary application of the device 100 to a plug designed for a bath tub.
  • the movable portion 1 is coupled to a plug 6, by coupling wings 11, whereas the fixed portion 2 is screw engaged with the drain 7.
  • the plug 6 comprises a gasket 8, for providing sealing properties, with the plug being closed, as shown in figure 5.
  • Figures 7 and 8 show an exemplary application of the device 100 to a wash-basin plug element.
  • the movable portion 1 is coupled to a plug 6, by coupling wings 11, as in the preceding application, whereas the fixed portion 2 is screw engaged with the drain 17.
  • the plug 6 comprises a gasket 8, providing the plug with sealing properties in its closed position, as shown in figure 7.
  • the drain 17 is suitably shaped, and comprises side holes 18, adapted to communicate the wash-basin outlet with the ducts formed in the gap 19 of the ceramics bowl 21, coupled to the overflow outlet thereof.
  • the top portion of the drain 17 is of tapering configuration and, at the bottom thereof, a sealing gagket 20 is applied to the drain, for preventing water from entering the space between the drain and top surface of the ceramics bowl 21.
  • the movable portion 1 in particular, is rigidly fastened to the plug 6 and is designed for providing an axial movement, i.e. a vertical movement, with respect to the fixed portion 2 which is mounted on the drain, 7 or 17, and which is stationary.
  • the rotary portion 3 in turn, can perform an axial and rotary movement, and is urged to contact the fixed portion 2 under the urging force applied by the spring 4.
  • the movable portion 1, which is rigid with the plug 6, will be axially displaced thereby causing the rotary portion 3 to turn, owing to the combined effect of the inclined abutment elements 12, provided on the fixed portion 2, and of the front teeth 13, provided on the rotary portion 3, and also having an inclined configuration.
  • Figure 3 shows the device according to the invention in a condition thereof corresponding to an open position of the plug, with the maximum raising opening stroke, and in which the movable portion 1 abuts against the fixed portion 2 through a bottom i inner edge 15, provided for abutting against the bottom surface of the inclined abutments 12 of the fixed portion 2.
  • Figure 4 shows a condition of the device according to the invention corresponding to a closure condition of the plug, in which the movable portion 1 is lowered so as to cause the longitudinal inner ridges 14 to abut against the front teeth 13 of the rotary portion 3.
  • the invention provides a device which allows to easily open and close the plug of a bath tub, a wash-basin or other sanitary fitting, by simply applying to the plug a pressure force, by a hand, or by a foot, in the case of a bath tub, thereby eliminating all the leverages which were conventionally used in such an application.
  • the device according to the present invention provides a larger raising stroke for the plug, and accordingly a better raising stroke for the plug, and accordingly a better water outflow, and a less size of the device between the plug element and sanitary fitting drain.
  • the closure point shown in figures 5 and 7, in particular, will be determined by the weight of the plug, i.e. it is not rigidly determined by any mechanisms, thereby allowing to optimally exploiting the gasket.
  • the contacting and movable portion can be made of a plastics material, the friction therebetween will be very reduced, while providing a better movement without any electrocorrosion risks.
