Definitions

  • the present invention relates generally to faucets for sanitary fixtures such as sinks, washbasins, bidets, or the like, and more particularly to a faucet assembly having a separable faucet head and a sanitary fixture-engaging base having automatic water supply shut-off valves that allow quick and easy installation of the faucet head onto the sanitary fixture- engaging base without the need to manually turn the supply lines off and on.
  • faucets are generally applied to their respective sanitary fixtures by providing a through hole in a portion of the sanitary fixture where the faucet is to be applied, the base portion of said faucet being inserted into said through hole.
  • the faucet is fixed to the sanitary fixture by means of a plate that is placed on the lower side of the sanitary fixture and which is meant for engaging the edge of the through hole. The plate is then tightened against the lower face of the sanitary fixture by means of two or more screws which engage with the base portion of the faucet, after it is inserted in the through hole.
  • the base portion of the faucet protrudes below the through hole and has a screw threading so that it can be engaged by a ring nut.
  • the ring nut engages the lower face of the sanitary fixture, in the proximity of the edge of the through hole, thus fixing the faucet to the sanitary fixture.
  • the mounting operation of conventional faucets to sanitary fixtures is troublesome in that an installer must necessarily work under the sanitary fixture where space is cramped and difficult to reach parts necessary to the installation.
  • the mounting operation of the faucet is particularly difficult in that the installer must operate from the front of the sink whereas the faucet mounting hole is near the rear side between the two compartments which makes the access thereto particularly difficult.
  • the sanitary fixtures are usually placed resting against a wall, and the hole where the faucet is to be fixed, is proximate to this wall that hinders mounting operations of the faucet.
  • the mounting operations of faucets are also made complicated by the presence of a draining trap or column particularly when the faucet is installed onto a washbasin, as well as by the presence of the wall against which the sanitary fixture rests.
  • US Patent No. 6,328,059 to Testori and Brown discloses a faucet apparatus for mounting on sanitary surfaces comprising a block portion that is inserted into a hole within a sanitary surface that is connected below to water intake ducts, and above to a faucet head. Before the faucet head can be removed or reconnected, however, the water supply lines must first be manually shut off to prevent free-flow of water.
  • An object of the present invention is therefore to overcome the above mentioned drawbacks by providing a faucet assembly that is connected to sanitary fixtures such as sinks, washbasins, bidets, or the like, and allows an installer or service personnel to remove or replace a faucet head without the installer's having to manually shut off the water supply lines feeding the faucet assembly.
  • a particular object of the invention is to provide an automatic shut-off valve system that enables a faucet head to be easily mounted or removed from a faucet base, which is mounted on a sanitary fixture, without requiring that the installer climb or work from under the sanitary fixture.
  • Another object of the invention is to provide a device that enables the mounting of both conventional faucets and lever-type mono-control mixing valves and to enable their quick replacement.
  • a further object of the invention is to provide a device that can be manufactured at extremely low costs and thus will be very price-competitive in the marketplace.
  • a further object of the invention is to provide a device that enables coupling of faucet assemblies to a wide range of sanitary fixtures, including wash basins, bidets, and bathtubs.
  • a further object of the invention is to provide a device enabled for positioning the faucet water mixing assembly at a set angle relative to the sanitary fixture upon which it is mounted.
  • a further object of the invention is to provide a faucet assembly having low- voltage wiring and electrical connections to enable use of devices such as optical sensors for automatic faucet actuation.
  • a faucet apparatus for mounting on sanitary fixtures such as sinks, washbasins or the like, provides simple and quick installation of a faucet head without the need to manually shut off water supply lines.
  • the apparatus comprises the faucet head and a fixture engaging base portion that is inserted into a through hole in the sanitary fixture and is with a portion thereof above the sanitary fixture.
  • the faucet head is removable from the base, which stays attached to the sanitary fixture.
  • a pair of passages or conduits extends through the base and are adapted to be connected below the sanitary fixture to water supply lines, and above the sanitary fixture for supplying the faucet head.
  • the faucet apparatus further comprises automatic water supply shut-off valves disposed within the passages of the base and corresponding valve actuators disposed within the faucet head that allow quick and easy installation or removal of the faucet head assembly onto the sanitary fixture-engaging base without the need to manually turn the supply lines off and on.
  • the shut-off valves are each comprised of a normally closed valve assembly that, when the faucet head is not present, remain in a closed position by the presence of water pressure from the supply lines or by spring tension.
  • the faucet head assembly is comprised of a water dispensing unit, a pair of passages that align with the passages or conduits of the base, coupler fittings that engage with the faucet head passages at one end and with the base passages at a second end.
  • the corresponding valve actuators are located on the second end of the coupler fittings.
  • a plurality of o-ring seals affixed on the coupler fittings prevents undesired escape of water.
  • the coupler fittings engage and seal against the base passages, and as the faucet assembly moves axially with respect to the base conduits, the actuators engage and open each valve assembly, enabling water flow to the faucet head as the faucet head is fully seated onto the base.
  • the base further comprises an additional passage for allowing installation of low- voltage conductors and electrical connections to enable features such as automatic faucet actuation.
  • the faucet apparatus further comprises an attachment means for fixing the base portion to the sanitary fixture.
  • the attachment means comprises a fixing member associated with the base and moved from an insertion position in which the fixing member is axially aligned with the hole in the sanitary fixture, and a locking position in which the fixing member is able to engage the lower surface of the sanitary fixture in which the hole is made.
  • FIG. 1 is a side elevational view partly in section of a faucet assembly according to the present invention
  • FIG. 2 is a cross sectional view taken along lines 2-2 of Fig. 1.
  • the faucet assembly of this invention with the elements shown about to be assembled.
  • FIG. 3 is a cross sectional view taken along lines 2-2 of Fig. 1 of a faucet assembly showing parts thereon assembled.
  • FIG. 4 is an exploded perspective view of internal parts of the faucet assembly according to the present invention, showing the manner in which a faucet head assembly is engaged with the base portion.
  • FIG. 5 is a partial cross sectional view of a second embodiment showing a base portion of a faucet assembly, having a ball-type valve structure with the faucet conduits positioned above the base.
  • FIG. 6 is a partial cross sectional view of the device shown in Fig. 5 with the conduits of the faucet inserted into the base.
  • the apparatus comprises a base portion 2, which mounts within a through hole 3 defined in a sanitary fixture 4.
  • the sanitary fixture 4 is a sink, washbasin, bidet or the like.
  • An upper portion of the base portion 2 protrudes above the sanitary fixture 4 and can be housed within a lower cavity 51 of the faucet apparatus 5, and is removably fixed thereto.
  • the base portion 2 preferably of a substantially cylindrical shape, is coupled coaxially in the through hole 3 so as to be aligned with a vertical axis and in a perpendicular attitude to a upper face 4a of the sanitary fixture 4.
  • a relatively narrow portion of the lower base of base portion 2 defines a border 8 and engages the upper face 4a of the sanitary fixture 4 at the edge of the through hole 3.
  • a plurality of conduits preferably a pair of conduits 6 and 7, extend vertically through base portion 2, and can be connected below sanitary fixture 4 to water supply ducts (now shown).
  • the water intake ducts provide hot water and cold water, to a plurality of fittings 12 and 13, supplying the faucet apparatus 5 to be mounted to the sanitary fixture 4.
  • the water supply ducts 10 and 11 are connected to the lower mouths of the conduits 6 and 7, preferably by means of a threaded coupling, or by welding or other known connection techniques.
  • Cylindrical sealing gaskets 16 and 17 fit tightly around supply fittings 12 and 13. In turn, the cylindrical sealing gaskets 16 and 17 frictionally engage the inside surfaces of the cylindrical passages 6 and 7 .
  • the supply fittings 12 and 13 protrude upwardly from the base portion 2 and engage, with the interposition of sealing gaskets 14 and 15, the mouth of a supply duct 50 leading into a dispensing portion cavity 51 provided in the dispensing portion of the faucet apparatus 5.
  • the faucet apparatus further comprises automatic water supply shut-off valves 40, 41 disposed within the passages of the base and corresponding valve actuators 42, 43 disposed within the faucet head that allow quick and easy installation or removal of the faucet head assembly onto the sanitary fixture-engaging base without the need to manually turn the supply lines off and on.
  • the shut-off valves are each comprised of a normally closed valve assembly having a neoprene disk 44, 45 or ball stop 46, 47 that, when the faucet head is not present, remain in a closed position by the presence of water pressure from the supply lines or by spring 48, 45 that keeps the stop element engaged with the valve seat.
  • the faucet head assembly is comprised of a water dispensing unit, a pair of passages that align with the passages of the base, coupler fittings that engage with the faucet head passages at one end and with the base passages at a second end.
  • the corresponding valve actuators are located on the second end of the coupler fittings.
  • a plurality of o-ring seals affixed on the coupler fittings prevents undesired escape of water.
  • the actuators 42, 43 may be cone-shaped, ball-shaped or may simply be a protrusion extending from the end of the coupler fitting, provided with apertures that allow water flow around a valve-engaging tip of the actuator.
  • the valve seats may be those of any of a variety of in-line check valves as are commonly known in the art and are typically flat or tapered to engage and seal with a valve stop element. Neoprene stop elements are widely used as they provide long life and acceptable wear properties. It will be obvious to one of skill in the art that a wide range of valve stop and valve seat materials and methods of engagement will achieve the same function.
  • An attachment means comprises a fixing member 22 and a threaded screw 21 for fixing the base portion 2 to the sanitary fixture 4.
  • the threaded screw 21 is inserted into a attachment hole 27 that extends axially through the base portion 2.
  • a threaded fixing member (not shown) can be used to fix the faucet 5 in place upon base unit 4. Inserting and tightening the threaded member into threaded aperture 55 engages base 4 and prevents removal of faucet 5 therefrom.
  • the faucet head 5 is placed on the base portion 2, thus engaging the couplers of the faucet head with the passages at the top of the base, thereby engaging the valve actuators affixed to the coupler ends with the normally-closed valve assemblies disposed withing the base passages.
