Abstract
Description
- The present invention relates to a device for opening and closing a plug for sanitary fittings.
- Plugs for wash-basins, bath tubs, bidets and the like, comprising a mushroom elements which can be driven from the outside by a lever system, are already known.
- In particular, 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.
- Accordingly, the aim of the present invention is to provide a device for opening and closing a plug for sanitary fittings, which is improved with respect to conventional prior like plugs.
- Within the scope of the above mentioned aim, 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 requires any maintenance operations, and is very safe and efficient 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 device for opening and closing a plug for sanitary fittings, characterized in that said device comprises a movable portion, adapted to be coupled to a plug element, and slidably engaged with a fixed portion, mounted on 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.
- 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:
- Figure 1 is an exploded perspective view of the device for opening and closing a plug for sanitary fitting, according to the invention;
- Figure 2 is a perspective view of the device in an assembled condition thereof;
- Figures 3 and 4 are perspective views, as partially cross-sectioned, illustrating two operating steps of the device according to the present invention;
- Figure 5 is an elevation, cross-sectioned view, illustrating a plug for bath tubs, including the device according to the present invention;
- Figure 6 is a further perspective view of the plug for bath tubs, including the device according to the present invention;
- Figure 7 is an elevation, cross-sectioned view, of a wash-basin plug including the device according to the present invention; and
- Figure 8 is a further perspective view of a plug for wash-basin, including the device according to the present invention.
-
- With reference to the number references of the above mentioned figures, the device for opening and closing a plug for sanitary fittings, according to the present invention, and generally indicated by the
reference number 100, comprises amovable portion 1, adapted to be coupled to a plug element, and slidably engaged with afixed portion 2, adapted to be mounted on a drain of the sanitary fitting. - Inside the fixed
portion 2 is arranged arotary portion 3, including an axially extending hole, housing therein acoil spring 4, in turn engaged with aspring guide 5. - Figures 5 and 6 show an exemplary application of the
device 100 to a plug designed for a bath tub. - In such an application, the
movable portion 1 is coupled to a plug element 6, bycoupling wings 11, whereas thefixed portion 2 is screw engaged with thedrain 7. - The plug element 6 comprises a
gasket 8, for providing sealing properties, with the plug element 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. - In such an application, the
movable portion 1 is coupled to a plug element 6, bycoupling wings 11, as in the preceding application, whereas thefixed portion 2 is screw engaged with thedrain 17. - The plug element 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 comprisesside holes 18, adapted to communicate the wash-basin outlet with the ducts formed in thegap 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 sealinggasket 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 operation of the device according to the present invention is substantially the same, independently from its application.
- The
fixed portion 1, in particular, is rigid with the plug element 6 and is designed for providing an axial movement, i.e. a vertical movement, with respect to thefixed 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 fixedportion 2 under the urging force applied by thespring 4. - By pressing on the plug element 6, for example by a hand, the
movable portion 1, which is rigid with the plug element 6, will be axially displaced thereby causing therotary portion 3 to turn, owing to the combined effect of theinclined abutment elements 12, provided on thefixed portion 2, and of thefront teeth 13, provided on therotary 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 thefixed portion 2 through a bottominner edge 15, provided for abutting against the bottom surface of theinclined abutments 12 of thefixed 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 raised so as to cause the longitudinalinner ridges 14 to abut against thefront teeth 13 of therotary portion 3. - It has been found that the invention fully achieves the intended aim and objects.
- In fact, 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.
- With respect to prior devices, the device according to the present invention provides a larger 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.
- Also after a long period of use, a possible deterioration of the outer diameter of the gasket, will not hinder a proper sealing, since the plug, because of its weight, will be lowered for a greater distance, thereby allowing the gasket to operate on a less diameter of the drain, which has a conical intern contour.
- Moreover, since 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.
- On the other hand, in prior devices, the opening and closing movements are obtained by exploiting the motion of metal parts on plastic tracks, with a great friction and wear of the involved pieces.
- In practicing the invention, provided that they are compatible to the intended applications, can be any, according to requirements and the status of the art.
