Definitions

  • the present invention relates to a method for fixing a faucet to furniture such as a counter and a base member to be installed at a faucet mounting hole. More particularly, the present invention relates to a method for allowing a faucet to be easily and securely attached to a counter by work only at the top side of the counter using a base member (adapter) fixed to the counter.
  • a structure for fixing a desired article e.g. a faucet
  • a mounting surface of a mounting base e.g. a top of a counter
  • a structure as shown in Fig. 21 Conventionally employed as a structure for fixing a desired article, e.g. a faucet, to a mounting surface of a mounting base; e.g. a top of a counter, is a structure as shown in Fig. 21.
  • This structure includes a threaded pipe 202 attached to a faucet 200, a mounting hole 206 formed in a counter 204 in which the threaded pipe 202 is inserted, and a fixing nut 208 capable of screwing onto the threaded pipe 202.
  • This structure allows the faucet 200 to be fixed to the counter 204 by inserting the threaded pipe 202 into the mounting hole 206 from the mounting surface, i.e. the top, and screwing the fixing nut 208 onto the threaded pipe 202 at the hidden side of the counter 204.
  • an adapter assembly to be attached to a counter is proposed.
  • a faucet is fixed to the counter by the adapter assembly.
  • Figs. 22A, 22B show an example of well-known structures using such an adapter assembly (JP 02-158492 A).
  • numeral 210 designates an adapter assembly comprising an adapter 212, a pair of holders 214, and screw members 216 of which number (two) corresponds to the number of the holders 214.
  • the screw members 216 are first screwed into corresponding tapped holes 218 of the holders 214, respectively. Then, the pair of holders 214 are directed inward to face each other, that is the holders 214 are rotated toward the center of the mounting hole 206. In this state, the holders 214 are inserted into the mounting hole 206 from the top side of the counter 204.
  • the holders 214 are both rotated to face outward at the hidden side of the counter 204 and brought into contact with the underside of the counter 204.
  • the screw members 216 are screwed up at the top side of the counter 204 to install the adapter assembly 210 in the counter in such a manner that the counter 204 is sandwiched between the adapter 212 and the holders 214.
  • a lower end portion of the faucet 200 is fitted onto the adapter 212 and the faucet 200 is fixed to the adapter 212 with a fastener, thereby fixing the faucet 200 to the counter 204.
  • This structure has advantage that the adapter assembly 210 and the faucet 200 can be fixed to the mounting surface of the counter 204 only by work at the top side of the counter 204.
  • each holder 214 is each connected to the adapter 212 by one screw member 216, when the faucet 200, generally a spout 220, is exerted with force in the rotational direction exceeding its allowable limit, each holder 214 rotates and displaces about the axis of the corresponding screw member 216 relative to the adapter 212. This makes the faucet 200 shaky in the rotational direction so that the strength of fixation of the faucet 200 in the rotational direction around the mounting hole 206 is low relative to the counter 204.
  • a structure comprises an annular base member disposed on a top of a counter, a mounting member disposed on a underside of the counter, and a bolt inserted into a hole formed in the base member and then screwed into a tapped hole of the mounting member to fix the base whereby a faucet is fixed to the base.
  • the structure is known in the art (JP 09-259189 A).
  • FIGs. 3 8 through 40 are perspective views showing the structure of JP 09-259189 A
  • a counter 360 is provided with a mounting hole 361 (Fig. 40) formed therein on which an annular base member 363 is disposed.
  • a horseshoe member 364 is disposed beneath the mounting hole 361.
  • the base member 363 and the horseshoe member 364 are provided with openings 365, 366 (Fig. 39), respectively.
  • a bolt 367 is inserted into the openings 365 and 366 and a nut 368 is screwed onto an end of the bolt 367.
  • the horseshoe member 364 is inserted into the mounting hole 361 downwardly as shown in Fig. 40 so that the horseshoe member 364 is faced to the underside of the edge of the mounting hole 361.
  • the base member 363 is provided with external thread formed on the outer periphery.
  • a faucet 369 is fixed to the base member 363 using a fastening nut 370, like a union nut.
  • the horseshoe member 364 is provided with a slit 371 integrated into the opening 365 and the nut 368 is provided with projections 372 engaging with the slit 371.
  • the bolt 367 is pulled up in such a manner that the horseshoe member 364 comes in contact with the underside of the counter 360 and then the projections 372 of the nut 368 engages with the slit 371. Therefore, the bolt 367 can be screwed without involving the nut 368 in rotation.
  • a licking member 373 is inserted into a central hole 374 of the base member 363 to prevent the rotation of the horseshoe member 364 so that the bolt 367 is tightened.
  • the faucet 369 is fixed to the base member 363 by the fastening nut 370.
  • the fastening nut 370 is however conspicuous, not only spoiling the beauty but also becoming easy to suffer mischief of loosing the nut.
  • Figs. 26A and 27A are longitudinal sectional views showing the structure of fixing the faucet according to the invention of JP 10-317439 A
  • Figs. 26B and 27B are sectional views taken along a line 26B-26B of Fig. 26A and a line 27B-27B of Fig. 27A, respectively

  • Figs. 30 and 31 are exploded perspective views for explaining the structure.
  • a mounting hole 304 is formed in a counter 301 between a back guard 302 and a sink 303.
  • a base member 380 is fixed to the counter 301 through the mounting hole 304 by a horseshoe washer 382 and bolts 384.
  • the base member 3 80 is provided with two projections 3 83 projecting from the inner surface thereof and through holes 383H formed in the projections 383 into which the bolts 384 are inserted, respectively.
  • the base member 380 is also provided with four small projections 385 projecting from the inner surface thereof which project downwardly from the lower end of the base member to come in contact with the inner surface of the mounting hole 304.
  • a faucet body 386 has a concave portion 388 at the bottom thereof which fits onto the base member 380 and connected to the base member 380 by a machine screw 390 and an engaging member 392.
  • the base member 380 is provided with a tapped hole 394 at a portion facing the front of the counter 301.
  • the machine screw 390 is screwed into the tapped hole 394 through a head hole 396 formed in the faucet body 386 and an opening 412 formed in a cover ring 410 described later.
  • the engaging member 392 is held by a window 400 formed in a lower portion of the faucet body 386.
  • the window 400 comprises, as shown in Fig. 30 and Fig. 31, stepped portions 402, each of which a pin 392c of the engaging member 392 comes into contact with, and a concave portion 404 into which a head 392a of the engaging member 392 is fitted.
  • the engaging member 392 comprises the disc-like head 392a, a pair of legs 392b projecting from the head 392a, and four pins 392c projecting from the upper and lower faces of.the respective legs 392b.
  • the legs 392b are elastic. When no external force is exerted on the legs 392b, the legs 392c project from the inner surface of the faucet body 386 through the window 400.
  • the base member 380 is provided with concave portions 406 in the outer surface thereof into which the legs 392b are entered, respectively.
  • the cover ring 410 covers to surround a lower outer periphery of the faucet body 386.
  • the cover ring 410 has the opening 412.
  • the base member 380 is first fixed to the.counter 301 by the washer 382 and the bolts 384 and then the concave portion 388 of the faucet body 386 is fitted onto the base member 380.
  • the engaging member 392 is previously fitted in the window 400 of the faucet body 386 and the faucet body 386 is previously covered by the cover ring 410.
  • the opening 412 of the cover ring 410 and the head hole 396 of the faucet body 386 are previously aligned.
  • the head 392a of the engaging member 392 is pressed by the cover ring 410 and the legs 392b are housed in the window 400.
  • the pins 392c are in contact with the stepped portions 402, the head 392a is pressed from the outside into the window 400 by the cover ring 410 so that the legs 392b are housed in the window 400 as shown in Fig. 29.
  • the faucet body 386 is fitted onto the base member 380 (Figs. 27, 29). Then, the machine screw 390 is screwed into the tapped hole 394 through the opening 412 and the head hole 396 by a screwdriver D.
  • the cover ring 410 is turned by 180° in the circumferential direction of the faucet to align the opening 412 and the head 392a of the engaging member 392 so that the head 392a enters into the opening 412.
  • the legs 392b project from the inner surface of the faucet body 386 to enter in the concave portions 406, respectively. In this manner, the faucet body 386 is securely fixed to the counter 301.
  • the faucet body 386 is securely fixed to the base member 380 by the machine screw 390 at the front side and by the engaging member 392 at the rear side. Even when a lever of the faucet is operated, no backlash produces in the faucet body 386.
  • the cover ring 410 Since the head of the machine screw 390 is covered by the cover ring 410, users of the sink 303 cannot see the machine screw 390 so as not to spoil the beauty.
  • the cover ring 410 is prevented from rotating by the head 392a of the engaging member 392. Therefore, the cover ring 410 is not easy to suffer mischief of rotating the cover ring 410.
  • the machine screw 390 can be screwed into the tapped hole 394 by a tool such as a screwdriver at the front of the faucet 310. Since hands of worker may be disposed in the sink 303 during this working, it is easy to work so that the machine screw 390 can be tightened easily and firmly.

  • a base member 305 is fixed to the counter 301 through the mounting hole 304 by bolts 306 and mounting members 307.
  • the base member 305 is formed in annular shape and is provided with two convex portions 305a projecting from the inner surface thereof and through holes 305b formed in the convex portions 305a into which the bolts 306 are inserted, respectively.
  • Each mounting member 307 comprises, as shown in Fig. 34, a tongue portion 307a which comes in contact with the underside of the counter 301, a square block-like stopper 307b which comes in contact with the inner periphery of the mounting hole 304, and a tapped hole 307c.
  • the bolts 306 are inserted into the through holes 305b and the mounting members 307 are screwed onto ends of the bolts 3 06, respectively. During this, the tongue portions 307 are directed to face the center of the base member 305. In this state, the mounting members 307 are put into the mounting hole 304 downwardly until the base member 305 sits on the top of the counter 301. After that, the bolts 306 are screwed by a screwdriver so that the mounting members 307 turn with the bolts 306 by half circle as shown by an arrow ⁇ of Fig. 36 and the stoppers 307b come in contact with the inner surface of the mounting hole 304 so as to prevent the further rotation of the mounting members 307.
  • the tongue portions 307a are positioned beneath the counter 301.
  • the mounting members 307 move upward by its thread function so that the tongue portions 307a come in contact with the underside of the counter 301.

  • the faucet 310 is mounted to the base member 305 in such a manner that the concavity 319a is fitted onto the base member 305, After that, a machine screw 309 is inserted into a hole 308 formed in a rear face of the faucet 310 and is screwed into a tapped hole 309a of the base member 305, thereby fixing the faucet 310 to the base member 305.
  • the faucet 310 is a single-lever combination faucet of kitchen type comprising a faucet body 312 connected to a hot-water supply pipe 311H and a water supply pipe (described later with reference to Fig. 24), a mixing mechanism 313 disposed above the faucet body 312, a lever 314 for operating the mixing mechanism 313, an upper casing 315 covering the mixing mechanism 313, a middle casing 317 provided with a spout 316 integrally formed therein, and a top casing 318 putted on the upper casing 315.
  • the faucet body 312 comprises a cylindrical lower body 319 having the concavity 319a fitted onto the base member 305, a middle body 320 extending upwardly from the lower body 319, and an upper body 321 above the middle body 320.
  • a hot-water supply hole 322 and a water supply hole (not shown) connected to the hot-water supply pipe 311H and the water supply pipe 311L are formed through the middle body 320 and the upper body 321 and communicate with a hot-water supply port and a water supply port of a fixed valve element 323 in the mixing mechanism 313.
  • the communicating condition among the hot-water supply port and the water supply port and a combination port is switched by a movable valve element 324 so as to control the water temperature and rate of flow (mixed water) to a mixed water feed path 325 formed in the upper body 321.
  • the mixed water is spouted from the end of the spout 316 through a mixed water chamber 326 in the middle casing 317.
  • the base member 305 is fist fixed to the counter 301 by the bolts 306 and the mounting members 307 and then the faucet 310 is fixed to the base member 305.
  • the base member 305 can be mounted just by inserting downwardly the mounting members 307 into the mounting hole 304 and screwing the bolts 306 at the top side of the counter 301. Further, the bolts 306 are not required to be lifted and just required to be screwed.
  • the water supply pipe 311L and the hot-water supply pipe 311H extend downwardly from the roof portion of the concavity 319a of the faucet body 312 as shown in Fig. 24.
  • a discharge pipe 311M for the mixed water also extends downwardly from the roof portion of the concavity 319a as shown in Fig. 25.
  • a hose 311h is connected to the end of the mixed-water discharge pipe 311M.
  • the hose 311h is returned to the inside of the faucet body through the base member and is further connected to a shower head 316h through the spout 316'.
  • the shower head 316h is detachably mounted to the end of the spout 316'.
  • Such a base member used for fixing the shower type faucet has a relatively small outer diameter substantially the same as that of the faucet body and an inner diameter of the base member is smaller than the outer diameter.
  • the water supply pipe 311L and the hot-water supply type 311H are disposed at the front side of the faucet as shown in Fig. 24, while in case of the shower type faucet 310'as shown in Fig. 25, the water supply pipe 311L and the hot-water supply type 311H are disposed at the rear side of the faucet because the hose 311h should be disposed at the front side of the faucet. Therefore, the base member 305 for the shower type faucet should be reversed from the position of the case of normal type. The same is true of the case of the base member 380.
  • the convex portions 305a are positioned at the rear side of the faucet to form a relatively large space S 1 at the front side of the base member so that the water supply pipe 311L and the hot-water supply pipe 311H are inserted into the space S 1 .
  • a space S 2 formed behind the convex portions 305a is not enough to receive the two pipes 311L and 311H.
  • the base member is directed so that the convex portions 305a are positioned at the front side as shown in Fig. 25B to form the space S 1 at the rear side.
  • the base member 305, 380 may be mounted by a plumber. Since most of plumbers are not experienced in mounting this kind of base member, the plumber sometimes errs the direction of the base member and mounts the base member to the counter in the wrong direction. In this case, when intended to mount the faucet to the base member, pipes cannot be inserted to the base member so that the base member should be detached and mounted again. This doubles the trouble of fixing work.

  • a faucet 510 is provided with a lever 512 at the upper portion thereof in such a manner that the lever 512 can pivot vertically and horizontally.
  • the faucet 510 is provided with a drum portion 514 at the middle portion thereof in such a manner that the drum portion 514 can rotate in the circumferential direction and is provided with a spout 516 projecting from the drum portion 514.
  • a spout head 518 is detachably attached to the tip of the spout 516.
  • a hose 520 connected to the spout head 518 is withdrawn into the faucet 510 from the spout 516.
  • the hose 520 extends downwardly through the faucet 510 and is connected to the mixed-water discharge pipe 522.
  • a water supply pipe 524 and a hot-water supply pipe 526 extend downwardly form the faucet 510.
  • Water and hot water from the water supply pipe 524 and the hot-water supply pipe 526 are mixed by a mixing valve (not shown) disposed at an upper portion of the faucet 510 to supply mixed water at a desired temperature.
  • the mixed water is spouted from the spout head 518 through the mixed-water discharge pipe 522 and the hose 520.
  • ON/OFF can be switched and the mixing ratio of hot water can be controlled.
  • a body 530 comprises an upper body 530U, to which the mixed-water discharge pipe 522, the water supply pipe 524 and the hot-water supply pipe 526 are connected, a cylindrical lower body 530B, and a rear wall-like middle body 530M for connecting the upper body 530U and the lower body 530B.
  • the inside of the upper body 530U is divided into a water chamber, a hot-water chamber, and a mixed-water chamber.
  • the top surface of the upper body 530 U has a water port 532 formed above the water chamber, a hot-water port 534 formed above the hot-water chamber, and a mixed-water port 536 formed above the mixed-water chamber.
  • the mixing valve is disposed on the top of the body 530 and a top cover 538 (Figs. 44A and 44B) is fitted so as to cover the mixing valve.
  • a O-ring 540 (Fig. 45) is disposed between the upper body 530U and the drum portion 514 to seal therebetween.
  • the front side of the middle body 530M is an open area.
  • the hose 520 withdrawn in the spout 516 is entered into the body 530 through this open area and is pulled out from the lower body 530B in the same manner as the pipes 522, 524, 526.
  • the lower end of the hose 520 is provided with a union nut 542 (Figs 44A, 44B) to connect the hose 520 with the lower end of the mixed-water discharge pipe 522.
  • the hose 520 is also withdrawn in the cylindrical lower body 530B as shown in Figs. 44A, 44B, and 45. Since the diameter of the lower block 530B is quite small, the union nut 542 at the end of the hose 520 collides with the mixed-water discharge pipe 522, the water supply pipe 524 and the hot-water supply pipe 526, which are made of metal, during inserting the hose 520 into the spout 516 and pulling out the hose 520 from the lower block 530B so that it is difficult to insert the hose 520 in the body 530 due to the friction.

  • Correct positioning of the shells is determined by form elements provided on the shells to locate corresponding parts of the hydraulic unit. Specifically, from an inner surface of the lower shell there projects a rising edge of stepped cross-section to mate with a corresponding stepped edge provided on the lateral surface of the first mouth. The edge of a hole mating with the lateral surface of the second mouth also acts as a locator element.
  • the upper shell possesses a hole which substantially mates with the lower base of the body to act also as a locator element.
  • the base member of the present invention is a base member to be fixed to a faucet mounting plate such as a counter through a hole, a faucet being fixed by engaging the faucet with the base member from the upper side.
  • the base member is a cylindrical member disposed in such a manner that the axial direction thereof extends perpendicularly to the faucet mounting plate, the base member is asymmetrical with the back-and-fore direction in the state installed to the faucet mounting plate, and the base member is applied with a mark to indicate the front or rear side of the base member.
  • the mark applied on the base member facilitates the recognition of the correct direction of the base member.
  • the mark is made by coloring because it is easy to distinguished.
  • the base member of the present invention is symmetrical with the lateral direction in the state installed to the faucet mounting plate, as well as the base member of prior applications shown in Figs. 26 through 31 and Figs. 32 through 37, the base member has a pair of convex portions formed symmetrically with the lateral direction on the inner surface of the base member, wherein the convex portions are each provided with a through hole penetrating vertically and the convex portions are shifted to the front or rear side with reference to the center of the base member so that the base member is asymmetrical with the back-and-forth direction.
  • the method of the present invention is used for fixing a faucet to a counter by using such a base member.
  • the faucet is provided with a mark for indicating the mounting direction of the base member so that a plumber intending to fix the faucet can select the correct direction of the base member according to the mark.

Therefore, the same base member can be used both to a faucet with two pipes: a water supply pipe and a hot-water supply pipe as shown in Fig. 24 and to a faucet with a mixed-water discharge pipe and a hose besides the two pipes and the base member can be easily to recognize the correct direction of the base member.
  • a color A e.g. blue
  • a color B e.g. black
  • a faucet comprises: a faucet body to which a water supply pipe, a hot-water supply pipe, and a mixed-water discharge pipe are connected and extend downwardly; a spout pipe laterally projecting from the faucet body; a spout head detachably attached to the end of the spout pipe; and a hose which is connected to the spout head, downwardly penetrates the spout pipe and the faucet body, and is connected to the mixed-water discharge pipe, wherein the faucet has a lower part which fits to the base member mounted on the mounting base through the hole whereby the faucet is fixed, the lower part of the faucet is an annular part through which the water supply pipe, the hot-water supply pipe, the mixed-water discharge pipe and the hose are inserted.
  • the faucet is preferably provided with a guide piece for guiding the insertion of the hose, the guide piece extending from the annular part to the inside of the hole.
  • the guide piece for guiding the hose enables the hose to smoothly pass through the faucet body when inserting the hose into the faucet for installing the faucet.
  • the guide piece preferably comprises a cylindrical portion through which the hose is inserted, and a projection laterally projecting from an upper portion of the cylindrical portion and being in contact with the inner surface of the annular part, the outer surface of the cylindrical portion is contact with the hot-water supply pipe, the water supply pipe, and the mixed-water discharge pipe. It is preferable that the guide piece has a standing portion vertically standing on the cylindrical portion along the respective pipes. It is further preferable that the cylindrical portion and said standing portion are each provided with concavities into which the respective pipes are fitted. This structure allows the faucet to firmly withstand, by the guide piece, lateral force exerted on the pipes.
  • the faucet is preferably provided with a backup guide piece disposed at the opposite side of the guide piece with reference to the respective pipes, the backup guide piece being in contact with the inner surface of the annular part and the respective pipes. More Preferably, the backup guide piece is provided with concavities to which the respective pipes are fitted. This structtire allows the faucet to firmly withstand, by the guide piece, lateral force exerted on the pipes.
  • a base member is fixed to the mounting base through a hole of a counter and the faucet is fitted onto the base member at the top side of the counter
  • the base member is a cylindrical member disposed in such a manner the axial direction thereof extends perpendicularly to the counter
  • the lower end of the faucet is fitted onto the base member
  • the faucet is fixed to the base member by a screw fastener screwed into the base member through the lower portion of the faucet
  • a cover ring is rotatably fitted around the lower portion of the faucet to conceal the screw fastener
  • the cover ring has an opening or a recess at the rear side of the faucet, the opening or recess is formed to face the screw fastener by turning the cover ring
  • the lower portion of the faucet has a concave portion formed in the outer surface thereof, into which an elastic engaging member is inserted, and a part of the engaging member engages the opening or recess to prevent the rotation of the cover ring.
  • the screw fastener is covered by the cover ring so that the screw fastener is not visible even when the screw fastener is screwed at the front of the faucet, thereby improving the beauty and preventing the screw fastener from suffering mischief
  • the engaging member engages with the opening or recess of the cover ring, thereby preventing the undesired rotation the cover ring about the faucet.
  • the screw fastener is disposed on the front side of the faucet and the engaging member is disposed on the lateral side or the rear side of the faucet.
