The present invention relates to a lavatory faucet fixed on a basin with a central orifice, a left orifice, and a right orifice.
A conventional facet is installed in a narrow space below a basin which is located in a kitchen or a bathroom.
A positioning structure for a faucet disclosed in U.S. Pat. No. 8,763,175 B2 is fixed on the basin from an upper end of the basin. The faucet contains a body and a fixing device for installing the faucet on the basin from the upper end of the basin. The fixing device includes a mounting seat, two screw rods, and two clamping blocks. The mounting seat is inserted into an orifice on the basin and is employed to fix the body and to insert a supply pipe assembly. The supply pipe assembly has a first inlet pipe for flowing cold water, a second inlet pipe for flowing hot water and an inflow pipe for flowing a mixed water of the cold water and the cold water. The two screw rods are rotated to insert through the mounting seat from the orifice and are fixed by the two clamping blocks. When the two screw rods are rotated above the basin, they are positioned by the two clamping blocks and two stop stems on the mounting seat, such that the two clamping blocks are driven to force a bottom face of the basin, and the fixing seat and the body are clamped on the basin.
However, the faucet is applicable for the basin with a single orifice, because a diameter of the orifice is larger than 34 mm. Therefore, when the basin has three orifices, a diameter of which is less than 32 mm, the mounting seat cannot be fixed in the three orifices. Even through a size of the mounting seat is reduced, a channel in the mounting seat is decreased accordingly, so the supply pipe assembly cannot be mounted in the channel.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
One aspect of the present invention is to provide a lavatory faucet which is capable of overcoming the shortcomings of the conventional lavatory faucet.
To obtain the above, a lavatory faucet is fixed on a basin and contains: a body and a fixing device. The body includes a housing and a supply pipe assembly connecting with the body to delivery water; the fixing device includes a mounting seat, two screw rods, and two clamping blocks. The basin includes a central orifice, a left orifice, and a right orifice.
The mounting seat includes an upper fitting sleeve for connecting with the housing, two extending wings extending outwardly from a bottom end of an outer wall of the upper fitting sleeve to abut against a top face of the basin, and two support feet extending downwardly from two bottom ends of two outer walls of the two extending wings to insert through and to retain with the left orifice and the right orifice of the basin; the upper fitting sleeve has a channel defined therein relative to the central orifice of the basin so that the supply pipe assembly extends out of the central orifice via the channel; each extending wing has a through hole to insert each support foot; and each support foot has a first stopping fence formed on an outer wall thereof.
Each screw rod extends out of the through hole of the mounting seat and is rotated above the mounting seat.
Each clamping block is screwed with each screw rod and is limited by the first stopping fence of each support foot as rotating each screw rod, such that each clamping block moves upwardly to retain with a bottom face of the basin and to clamp the mounting seat and the body on the basin.
Thereby, the lavatory faucet of the present invention has advantages as follows:
1. The lavatory faucet is applicable for the basin with the central orifice, the left orifice, and the right orifice, the diameter of which is less than 32 mm.
2. The diameter of the channel is larger than that of the central orifice, and the two support feet are retained with the left orifice and the right orifice by ways of the two screw rods and two clamping blocks so that the mounting seat is fixed on the basin, and only the supply pipe assembly is inserted through the central orifice easily.
3. The two screw rods are rotated, and the two clamping blocks screwed with the two screw rods are rotated to accommodate in the two support feet or below two stop columns so that the fixing device is mounted on the basin easily, thereafter the two screw rods are rotated above the mounting seat of the basin so that the two clamping blocks engage with the bottom face of the basin tightly, thus fixing the fixing device. Accordingly, the body is fitted on the upper fitting sleeve of the fixing device, the supply pipe assembly is inserted through the central orifice of the basin from the channel of the upper fitting sleeve, thus fixing the lavatory faucet easily and quickly.
With reference to
An improvement of the lavatory faucet of the present invention is described as follows.
The mounting seat 30, as shown in
The upper fitting sleeve 31 has a channel 311 defined therein relative to the central orifice 3a of the basin 3 so that the supply pipe assembly 20 extends out of the central orifice 3a via the channel 311; each extending wing 32 has a through hole 321 to insert each support foot 33; and each support foot 33 has a first stopping fence 331 formed on an outer wall thereof.
Each screw rod 40 extends out of the through hole 321 of the mounting seat 30 and is rotated.
Each clamping block 50 is screwed with each screw rod 40 and is limited by the first stopping fence 331 of each support foot 33 as rotating each screw rod 40 tightly, such that each clamping block 50 moves upwardly to retain with a bottom face 3e of the basin and to clamp the mounting seat 30 and the body 1 on the basin 3.
A diameter of the channel 311 is larger than that of the central orifice 3a, as illustrated in
Each support foot 33 further has a second stopping fence 332 formed on the outer wall thereof adjacent to the first stopping fence 331, such that each clamping block 50 is limited as rotating each screw rod 40 loosely so that each clamping block 50 moves downwardly and remove from the bottom face 3e of the basin 3.
The first stopping fence 331 of each support foot 33 has an extending post 333 extending outwardly from a bottom end thereof; when each clamping block 50 is located opposite to the extending post 333, each screw rod 40 is rotated loosely, as shown in
Referring to
Each support foot 33 further has an aperture 334 passing through each extending wing 32, as illustrated in
Each screw rod 40 includes a defining sheath 41 screwing with a bottom end thereof, as shown in
Each clamping block 50 includes a plurality of engaging teeth 51 arranged on a top surface thereof, as illustrated in
The lavatory faucet further comprises a decorative slat 4 clamped between a bottom end of the body 1 and the top surface of each extending wing 32, as shown in
The mounting seat 30 further includes a bushing 34, as shown in
The lavatory faucet is a single handle faucet, so the housing 10 of the body 1 is formed in an inverted L shape and has a control valve (not shown) fixed in a top end thereof, a bottom end of the control valve is coupled with the supply pipe assembly 20, and the supply pipe assembly 20 includes a first inlet pipe 21 for flowing cold water and a second inlet pipe 22 for flowing hot water 22, and a mixing ratio of the cold water and the hot water is adjusted and controlled by an operating bar 60 mounted on a top end of the control valve, such that the cold water, the hot water or a mixed water of the cold water and the hot water flows out of an outlet 11 of the housing 10.
The lavatory faucet can be other types of faucets, such as a pull out faucet, wherein the housing 10 of the body 1 has a pull-out spray head disposed in a mouth thereof and an outflow pipe joined with the pull-out spray head and a bottom end of the control valve to flow the mixed water, such that the supply pipe assembly of the pull out faucet includes the first inlet pipe 21, the second inlet pipe 22, and the outflow pipe for flowing the cold water, the hot water or the mixed water toward the pull-out spray head. It is well-know that the outflow pipe is comprised of a valve pipe and a house connecting with the pull-out spray head. The upper fitting sleeve 31 is connected with the housing of the body of any type of faucet.
Thereby, the lavatory faucet of the present invention has advantages as follows:
1. The lavatory faucet is applicable for the basin 3 with the central orifice 3a, the left orifice 3b, and the right orifice 3c, the diameter of which is less than 32 mm.
2. The diameter of the channel 311 is larger than that of the central orifice 3a, and the two support feet 33 are retained with the left orifice 3b and the right orifice 3c by ways of the two screw rods 40 and two clamping blocks 5 so that the mounting seat 30 is fixed on the basin 3, and only the supply pipe assembly 20 is inserted through the central orifice 3a easily.
