Description

Fixing structure of a tap.

Field of the Invention

The present invention relates to a structure to fix an article such as a tap on a piece of furniture such as a countertop More particularly, the present invention relates to a suitable structure to be able to easily hold and with safety a faucet to a countertop working only from the top side of the countertop and using a base element (adapter) that is fixed to the countertop. The present invention is also refers to a structure for fixing an article to a wall attached, such as a towel rail, using the base element.

Prior art

A structure is shown in Figure 21 conventionally used to fix a desired item, by example a tap, on a mounting surface of a base of assembly, for example the top of a countertop.

This structure includes a threaded tube 202 attached to a tap 200, a mounting hole 206 practiced in a worktop 204, into which threaded tube 202 is inserted, and a fixing nut 208 capable of screwing into threaded tube 202. This structure allows to fix the tap 200 on the countertop 204 inserting the threaded tube 202 into the mounting hole 206 from the mounting surface, that is the upper part, and screw the fixing nut 208 on the threaded tube 202 on the hidden side of Countertop 204.

However, this structure requires screwing and tighten the fixing thread 208 on the hidden side of the countertop 204. This reduces the efficiency of the installation's work since It takes a long time to fix the tap.

To solve this problem, a adapter set to attach to a countertop. The tap is set to the countertop through the adapter set.

Figures 22A, 22B show an example of known structures using said adapter set (JPA S63-312435).

In these figures, the number 210 designates a adapter set comprising an adapter 212, a pair of fasteners 214, and screw elements 216 whose number (two) corresponds to the number of fixations 214.

In this structure, they are screwed in first the screw elements 216 in the corresponding holes threads 218 of the respective fasteners 214. Next, orient the two fixings 214 inwards leaving them facing each other, that is, the bindings 214 are turned towards the center of mounting hole 206. In this state, the fasteners 214 by mounting hole 206 from the side worktop top 204.

Once the 214 fixings have been introduced, the turn to face out and get in touch with the underside of countertop 204. In this state, it tighten the screw elements 216 by the upper side of the worktop 204 to install adapter assembly 210 in the countertop, so that countertop 204 is sandwiched between the 212 adapter and 214 fixings.

Next, an adapter 212 is mounted on lower end of tap 200 and tap 200 is fixed on the adapter 212 by means of a screw, which fixes the tap 200 on countertop 204.

This structure has the advantage that the adapter assembly 210 and faucet 200 can be fixed on the worktop mounting surface 204 working solely for the upper side of the countertop 204.

However, the structure has the problem next. Since each of the fixtures 214 is connected to adapter 212 by means of a screw element 216, when exerts on tap 200, generically on a spout 220, a force in the direction of rotation that exceeds the permissible limit, each fixing 214 rotates on the axis of the corresponding element of screw 216 and moves with respect to adapter 212. This produces a tap tap 200 rotationally and therefore reduces the resistance to rotation of the tap 200 over the mounting hole 206 of the countertop 204.

There is also the possibility that the fixation 214 exit through mounting hole 206 of countertop 204 due to the rotation of the fixation 214.

Although the above description corresponds to case of fixing the tap on a mounting base such as a countertop, the aforementioned problems are common to cases of fixing a article other than a tap on a certain basis of mounting.

In the case of fixing a tap in the hole of assembly of a countertop or the edge of a sink, since the faucet is located behind a sink or sink, the work of holding the tap must be carried out behind the battery or the washbasin, so the operator will have to adopt a posture of very difficult work, which reduces the work performance of installation. In addition, a special key is required to tighten a nut from the front of the sink or sink.

In EP 0 293 655 A1 a tap is mounted on a mounting base, for example a table, which has a opening. An adapter to fix the tap on the basis of assembly, or is formed integrally with the mounting base, or it is inserted into said opening, the adapter being designed  so that the tap can be attached to the adapter from the side upper mounting base.

Consequently, various structures to fix a tap on a mounting hole of a mounting base, such as a countertop or an edge of a washbasin, working only on the upper side of the structure mounting

One of the structures comprises an element of annular base arranged on the top side of a countertop, a mounting element arranged on the underside of the countertop, and a screw that is inserted through a hole in the base element and then screwed into a threaded hole of the mounting element to fix the base and then fix a tap to the base. The structure is known in the art (JPA H08-93012).

Figures 38 to 40 are views in perspective showing the structure of the JPA document H08-93012. A 360 countertop is provided with a mounting hole 361 (Figure 40) practiced on it and on which places an annular base element 363. Below the mounting hole 361 is placed a horseshoe element 364. The base element 363 and the horseshoe element 364 are provided of openings 365, 366 (Figure 39), respectively. Is according In Figure 39, a screw 367 is inserted through the openings 365 and 366 and a nut 368 is screwed into one end of the screw 367. Next, the horseshoe element is introduced 364 through mounting hole 361 downstream, as shown in Figure 40, so that the horseshoe element 364 face towards the bottom side of the edge of the hole assembly 361.

Then screw 367 and the edge of mounting hole 361 is tight between the element of horseshoe 364 and base element 363, thus fixing the base element 363 on the countertop 360.

The base element 363 is provided with a outer thread formed on its outer periphery. About the element of base 363 a tap 369 is fixed using a clamping nut 360, such as a union nut.

The horseshoe element 364 is provided with a slot 371 integrated in opening 365 and nut 368 is provided with projections 372 that fit in slot 371. Before tightening screw 364, the screw is pulled up 367 so that the horseshoe element 364 contacts with the bottom side of the counter 360 and projections 372 of the nut 368 fit into slot 371. In this way it can be tightened screw 367 without turning nut 368. Next, it will introduces a support element 373 through the central hole 374 of the base element 363 to prevent rotation of the horseshoe element 364 when screw 367 is tightened.

In the conventional structure for fixing taps mentioned above, tap 369 is fixed on the base element 363 using clamping nut 370. Without However, the clamping nut 370 is very visible, which not only spoils the aesthetics but it is also easy to get lost accidentally the nut.

Therefore, the applicant for this Application has proposed, in Japanese Patent Application No. H09-133583, a structure for fixing taps in the which fits the bottom end of the tap into the base element and the tap is fixed on the base element by means of a screw prisoner.

Figures 26A and 27A are sectional views longitudinal showing the structure to fix taps according to the invention of Application No. H09-133583, the Figures 26B and 27B are sectional views taken respectively. by a line 26B-26B of Figure 26A and by a line 27B-27B of Figure 27A, and Figures 28 and 29 are sectional views taken respectively by a line 28-28 of Figure 26A and along one line 29-29 of Figure 27A. Figures 30 and 31 are broken perspective views to explain the structure.

A countertop 301 has a hole made of assembly 304 between a trailing edge 302 and a stack 303. A base element 380 is fixed to the countertop 301 through the mounting hole 304 using a horseshoe washer 382 and screws 384.

The base element 380 is provided with two projections 383 that project from the inner surface of the same and through 383H through holes formed in the projections 383 and by which the respective ones are introduced 384 screws.

The base element 380 is also provided with four small 385 projections that are projected from the inner surface thereof, down and at the end bottom of the base element, to come into contact with the inner surface of mounting hole 304.

A body 386 of the tap has at its bottom a concave part 388 which fits on the base element 380 and is connects to base element 380 by means of a captive screw 390 and a hooking element 392.

The base element 380 is provided with a threaded hole 394 in a part facing the front of the countertop 301. The captive screw 390 is screwed into the hole threaded 394 through a conical hole 396 formed in the body 386 of the tap and an opening 412 formed in a ring of coating 410 described below.

The coupling element 392 is held by a window 400 formed in a lower part of the body 386 of the tap. Window 400 comprises, as shown in Figure 30 and the Figure 31, staggered parts 402, each of them in contact with a pin 392c of the coupling element 392, and a concave part 404 in which a head 392a of the element of hitch 392. The hitch element 392 includes the head 392a in disk shape, a pair of 392b legs that project from the head 392a, and four spikes 392c that project from the faces upper and lower of the respective legs 392b.

The legs 392b are elastic. When not exercised no external force on legs 392b, legs 392c are project from the inside surface of the body 386 of the tap to through window 400. The base element 380 is provided in its outer surface of concave parts 406 in which the respective legs 392b penetrate. The coating ring 410 surrounds an outer lower periphery of the faucet body 386. He Coating ring 410 has an opening 412.

To fix the tap body 386 on the countertop 301, the base element 380 is first fixed on the countertop 301 using washer 382 and screws 384, and then the concave part 388 of the faucet body 386 is adjusted on the base element 380. Previously the coupling element 392 in the window 400 of the tap body 386 and the tap body 386 has been previously covered with the ring of coating 410.

In this case, the opening 412 of the ring coating 410 and conical hole 396 of faucet body 386 They have been previously aligned. In this state, head 392a of hooking element 392 is pressed by the ring coating 410 and legs 392b are housed in window 400.  As the pins 392c are in contact with the staggered parts 402, the cover ring 410 presses the head 392a towards the window 400 from the outside so that the legs 392b they are housed in window 400 as shown in Figure 29.

In this state, in which the legs 392b are housed in the window 400, the body 386 of the tap is mounted on the base element 380 (Figures 27, 29). Then it curls the captive screw 390 in the threaded hole 394, through the opening 412 and the conical hole 396, by means of a screwdriver D.

Then, the ring is rotated 180º coating 410 in the circumferential direction of the tap for align opening 412 and head 392a of the hitch element 392 so that the head 392a penetrates the opening 412. According to shown in Figures 26, 28, legs 392b project from the inner surface of the tap body 386 to penetrate into the respective concave parts 406. Thus, the body 386 of the tap is fixed securely on countertop 301.

In this structure, the faucet body 386 is securely held on the base element 380 by the captive screw 390 on the front side and through the hook element 392 from the rear side. Even when it actuate the tap lever, there is no movement of the 386 tap body.

Since the head of the captive screw 390 is covered by the cover ring 410, the user of the battery 303 cannot see the captive screw 390, so it is not It hurts aesthetics. Coating ring 410 cannot turn due to the head 392a of the hitch element 392. So so much it is not easy for the coating ring 410 to rotate accidentally.

As shown in Figure 27, the screw prisoner 390 can be screwed into threaded hole 394 by the front of the faucet 310 by a tool such as a screwdriver. Since during this operation the operator you can put your hands in stack 303, work is easy and the captive screw 390 can be tightened easily and firmly.

Figures 32 to 37 are explanatory views of a base element and a structure to fix taps using the base element described in Japanese Patent Application No. H09-11178, whose applicant is the same as this Request. Figure 32 is a sectional view showing the structure for fixing taps according to an embodiment of the Request No. H09-11178, Figure 33 is an exploded view thereof, Figure 34 is a perspective view of a mounting element, Figure 35 is an exploded view showing One way to mount the base element, Figure 36 is a view in plan that shows a state of assembly of the base element and Figure 37 is a sectional view taken along the line 37-37 of Figure 36.

A countertop 301, which acts as a plate assembly, it has practiced a mounting hole 304 between an edge rear and a stack 303. On the countertop 301 an element is fixed base 305 through mounting hole 304 by means of screws 306 and mounting elements 307. The base element 305 has an annular shape and is provided with two convex parts 305a that are projected from the internal surface of the same and through of holes 305b formed in convex parts 305a and in which the respective screws 306 are introduced.

Each mounting element 307, as shown in Figure 34, comprises a tongue part 307a which is placed in contact with the underside of the countertop 301, a stop 307b in square block shape that contacts the periphery internal of mounting hole 304, and a threaded hole 307c

As shown in Figure 35, the screws 36 are inserted into the through holes 305b and the elements of assembly 307 are screwed into the ends of the respective screws 306. Meanwhile, the tongue parts 307 are oriented towards the center of the base element 305. In this state, the mounting elements 307 are introduced into the hole of assembly 304, lowering them until the base element 305 is supported on the countertop 301. Next, the screws are tightened 306 with a screwdriver so that the mounting elements 307 turn half circle together with screws 306, as shown in the arrow the of Figure 36, and stops 307b enter contact with the inner surface of mounting hole 304 to prevent the mounting elements from rotating 307. In this state, the tongue parts 307a are located below of countertop 301. When screws 306 continue to turn, the mounting elements 307 are moved up by the function of its thread and tongue portions 307a come into contact with the underside of countertop 301. If they are sufficiently tightened the screws 306, the edge of the mounting hole 304 is firmly sandwiched vertically between base element 305 and the mounting elements 307, whereby the base element 305 It is firmly attached to the countertop 301.

The faucet 310 is then mounted on the base element 305. The faucet 310 has a concavity 319a at its lower end. The faucet 310 is mounted on the element of base 305 such that concavity 319a fits over the base element 305. Next, a screw is inserted prisoner 309 in an existing hole 308 on a rear face tap 310 and is screwed into a threaded hole 309a of the element of base 305, thus fixing the faucet 310 on the base element 305

The faucet 310 is a kitchen-type mixer tap comprising a body 312 of the tap connected to a tube 311H of hot water supply and to a water supply tube (described below with reference to Figure 24), a mechanism mixer 313 located above the faucet body 312, a lever 314 for operating the mixing mechanism 313, an upper housing 315 covering the mixing mechanism 313, an intermediate housing 317 provided with a 316 spout integrally formed therewith, and a final housing 318 placed on the upper housing 315.

The faucet body 312 comprises a body cylindrical bottom 319 whose concavity 319a fits over the base element 305, an intermediate body 320 extending up from lower body 319, and upper body 321 above intermediate body 320.

The intermediate body 320 and the upper body 321 are traversed by a water supply hole 322 hot and through a water supply hole (not shown) connected to the 311H hot water supply tube and the tube 311L water supply, and they are connected with a mouth of hot water supply and with a water supply mouth of a fixed valve element 323 of the mixing mechanism 313. Al actuate lever 314 vertically and horizontally, the condition of communication between the hot water supply mouth and the mouth of water supply and a combined mouth is switched, by means of a mobile valve element 324, to control the temperature and the water flow (mixed water) to a path 325 of mixed water feed formed in upper body 321. The mixed water flows to the end of pipe 316 through a 326 mixed water chamber in the intermediate housing 317

As mentioned earlier, to fix the faucet 310 on the countertop 301, first the base element 305 on countertop 301 using screws 306 and mounting elements 307, and then the tap 310 on the base element 305. The base element 305 can be mounted by simply entering the elements down mounting 307 through mounting hole 304 and tightening the screws 306 from the top side of countertop 301. Also, no Screws 306 need to be lifted, but only accurate tighten them.

When the previous tap is a combined tap normal as shown in Figures 32 to 37, and not of the type shower (for head washing), water supply tube 311L and the hot water supply tube 311H extend towards down from the top of the concavity 319a of the body 312 of the tap, as shown in Figure 24.

When the tap is a 310 'combined tap of shower type, as shown in Figure 25, there is also a tube 311M mixed water outlet extending down from the upper part of the concavity 319a as shown in the Figure 25. A flexible pipe 311h is connected to the end of the 311M mixed water outlet tube. The 311h flexible pipe returns to the inside of the tap body through the element of base and is connected to a shower head 316h through the spout 316 '. The shower head 316h is removably mounted on the end of the pipe 316 '.

This base element that is used to fix the shower type faucet has a relatively outside diameter small, substantially equal to the tap body, and the inner diameter of the base element is smaller than the diameter Exterior.

Since there are some projections in the inner surface of the base element of smaller internal diameter, the interior space of the base element 303, 380, in which introduce the tubes, it is considerably small.

In the case of the tap other than the type of shower, the water supply tube 311L and the water supply tube 311H Hot water are located on the front side of the tap, according to It is shown in Figure 24, while in the case of tap 310 ' of shower type, shown in Figure 25, tube 311L of water supply and 311H hot water supply tube they are located on the back side of the tap because the pipe flexible 311h has to be located on the front side of the tap. Therefore, the base element 305 for the type tap Shower will have its position reversed with respect to the normal type. This is equally true in the case of the base element 380.

In the case of the faucet other than the shower type, the convex parts 305a are located on the rear side of the tap to form a relatively large S1 space on the side front of the base element and to be able to introduce the 311L tube of water supply and 311H hot water supply pipe in the space S1. A space S2 formed behind the parts Convex 305a is not large enough to accommodate the two tubes 311L and 311H.

On the other hand, in the case of the type tap shower, it is necessary to introduce three tubes: the supply tube 311L of water, 311H hot water supply tube, and tube 311M mixed water outlet, whereby the base element is oriented so that the convex parts 305a remain located on the front side, as shown in Figure 25B, to leave the space S1 on the back side.

As mentioned earlier, it is necessary know, depending on the type of tap, the correct orientation of the base element 305, 380 that allows to fix the tap acting only from the top side, and mount the base element with the correct orientation.

In most cases, the base element 305, 380 will be mounted by a plumber. Since most of Plumbers have no experience of mounting this type of base element, sometimes the plumber misses the orientation of the base element and mount the base element on the countertop in The wrong sense. In this case, when trying to mount the tap on the base element, the pipes cannot be introduced through the base element, so it will be necessary to release the element of base and mount it again. This doubles the work of the fixation.

Figure 44A is a perspective view that shows an example of a conventional combined type tap shower, and Figure 44B is an enlarged sectional view taken by line 44B-44B of Figure 44A. A 510 tap It has a lever 512 that can pivot at the top vertically and horizontally. The faucet 510 is provided in its part intermediate of a drum part 514, such that the part of drum 514 can rotate in the circumferential direction and is provided of a pipe 516 that is projected from the drum part 514. A shower head 518 is detachably attached to the tip of the spout 516. A flexible pipe 520 connected to the shower head 518 penetrates tap 510 from pipe 516. Flexible pipe 520 extends down through faucet 510 and is connected to the 522 mixed water outlet pipe.

In addition to the mixed water discharge tube 522, a water supply tube 524 and a water supply tube 526 Hot water extend down from faucet 510. Water and the hot water coming from the water supply tube 524 and of the hot water supply tube 526 are mixed by a mixing valve (not shown) located at the top tap 510 to supply mixed water at the temperature desired. Mixed water reaches shower head 518 through 522 mixed water outlet pipe and flexible pipe 520. By operating lever 512, the tap can be opened and closed and control the degree of mixing of hot water.

Figure 45 is a perspective view exploded from the main parts of this combined tap. A body 530 comprises a top body 530U, to which they are connected the mixed water outlet tube 522, the tube 524 of water supply and hot water supply tube 526, a 530B cylindrical lower body, and a 530M intermediate body in rear wall shape that connects 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 highest surface of the body upper 530U has a 532 mouth for water formed on the chamber of water, a mouth 534 for hot water formed on the chamber of hot water and a mouth 536 for mixed water formed on the mixed water chamber.

The mixing valve is located above the body 530 and is covered by a top cover 538 (Figures 44A and 44B). Between the upper body 530U and the drum part 514 is place an O-ring 540 (Figure 45) to get a tightness between both.

The front side of the intermediate body 530M is An open area. Flexible pipe 520 introduced by the pipe 516 penetrates body 530 through this open area and passes by the lower body 530B in the same way as the tubes 522, 524, 526. The lower end of the flexible pipe 520 is provided of a union nut 542 (Figures 44A, 44B) to connect the flexible pipe 520 to the lower end of the outlet pipe 522 of mixed water

In the case of the shower type faucet, in addition to the tube 522 mixed water outlet, tube 524 supply water, and the hot water supply tube 526, the pipe flexible 520 also passes through the cylindrical lower body 530B, as seen in Figures 44A, 44B, and 45. Since the lower body diameter 530B is quite small, the nut of junction 542 of the end of the flexible pipe 520 interferes with the 522 hot water outlet pipe, 524 supply pipe water and the hot water supply tube 526, which are metallic, during the introduction of the flexible pipe 520 in the spout 516 and the passage of flexible pipe 520 through the body lower 530B, so it is difficult to introduce the pipe flexible 520 in body 530 due to friction.

Particularly when the work of fixing on the top side of the countertop using the element base as shown in Figures 26A to 31 and 38 to 40, the union nut 542 of the end of the flexible pipe interferes with a corner part of the inner periphery of the element of base, so it takes a long time to introduce the pipe flexible.

It is an object of the present invention to resolve this problem and facilitate the introduction of a flexible pipe by the body of a shower type faucet.

In a structure for fixing taps described in Japanese Patent Application No. H09-11178 and shown in Figures 32 to 35, faucet 316 can be fixed on the countertop 301 fixing only the base element 305 to countertop 301 with screws 306 and mounting elements 307 and adjusting the faucet 310 on the base element 305 and fixing it with the captive screw 309. Therefore, the work Fixing is simple.

Since the screw head 309 to fix the faucet 310 to the base element 305 is, however, exposed outward, it is easy for the 309 stud screw may be damaged The screw 309 should be screwed on the back side (the back side) of tap 310 to avoid damage, but this takes a long time to screw the captive screw 309.

It is an objective of the present invention provide a structure to fix a tap that allows a easy and safe tap installation and also provide a good duration.

Summary of the Invention

The mentioned objectives can be achieved by a structure as defined in claim 1. The dependent claims define preferred embodiments or advantageous of the present invention.

A fixing structure of the present invention includes an adapter assembly comprising: an adapter arranged on a top or front surface of a base of assembly to which an article is attached; a fixation that enter through the hole from the top or front side of the mounting base so that the fixing is arranged to overlap a rear surface of the mounting base and cooperate with the adapter to tighten the mounting base vertically; Y some screws to connect the adapter and fixing through of the hole and tighten the mounting base between the adapter and the fixation. The adapter assembly is attached to the mounting base and the article is fixed on the body of the adapter, so the item is fixed on the mounting base. The fixation is connected to the adapter by a minimum of two screws.

In this structure, since the adapter and the fixing are connected by a plurality of screws, the adapter and fixation do not move in a rotational direction though an external force is exerted in a rotational sense on the item once installed, thus increasing the fixing force in rotational sense

Therefore, the article does not loosen in sense circumferential with respect to the base mounting surface mounting and fixing does not leave the mounting base through of the hole.

The present invention has an application suitable in the case of fixing a tap on a mounting base such Like a countertop

The fixation can have a curved shape that extend over the periphery of the hole and correspond to the hole shape, and the circumferential length can be made of the fixation is greater than the diametral length of the fixation.

This structure allows the fixation to be in contact with the bottom side of the mounting base over an area wider and over a greater distance in direction circumferential, which increases the clamping force between the fixing and adapter.

According to this structure, only one is sufficient fixing for the adapter assembly, which reduces the number of pieces.

Since the fixation is long in the direction circumferential, the adapter and the fixing are connected by the screws in positions spaced from each other in direction circumferential, thereby increasing resistance to distortion between the adapter and the rotation direction fixing and resistance in the rotational direction is effectively increased.

The screws are preferably located in both ends of the fixation in the circumferential direction, or near thereof.

Since the fixation is shaped like an arch circular corresponding to the shape of the hole, fixing no interferes when tubes are introduced through the hole water supply, to fix a tap, since there is a large hole space.

According to the present invention, the fixation can be constituted by a straight and rectangular element.

The fixation can be retractable in the direction longitudinal, so that the maximum dimension of the fixation is larger than the diameter of the hole but the minimum dimension of the fixing is smaller than the diameter of the hole.

In this case it is easy to introduce the fixing by the hole In addition, the fixation can be introduced by the hole after having previously screwed a pair of screws in a pair of threaded holes of the fixing, of so that the fixing and the adapter are connected to each other. After introduction, both ends of the fixation can overlap with the bottom side of the mounting base, which increases the efficiency of the assembly installation work adapter.

When the fixation is curved, the fixation can be deformable by a certain part of it so that it closes or opens on itself, thus facilitating the introduction of the fixation through the hole. In addition, fixing can be inserted into the hole after connecting the fixing and adapter to each other using a pair of screws, thus increasing the efficiency of the assembly installation work adapter.

When a pair of screws are screwed into threaded holes of the fixing through the adapter, the adapter holes are preferably torn holes for that the screws can move with respect to the fixing in correspondence to the shortening and lengthening of the fixation to warp to close or open.

When the fixation is curved and is deformable in the direction of closing and opening, it is preferable that the fixation can be elastically deformed in the direction of close and can return to its original form by force of Recovery.

In this case, when the strength of deformation once the deformed fixation is introduced in the direction of the closure in the hole, the fixation can return automatically to the original shape overlapping the bottom side of the base of assembly, and thus facilitating the work of fixing the assembly adapter.

When the fixation is curved and is elastically deformable, the fixation can be made of resin and provided with a thin wall part in a predetermined part in circumferential direction so that the fixation is deformable

When the fixation is retractable in the direction longitudinal or deformable to be introduced into the hole, the fixation can have a guiding face formed on the side bottom of it, whose guiding face comes into contact with the periphery of the hole and suffers a driving force that deforms the fixation so that it can be introduced into the orifice.

In this way, the fixation can be entered easily in the hole.

According to the present invention, once introduced fixing in the hole in a state in which the adapter and the fixation were previously attached with one of the screws, it shifts the fastener so that it overlaps with the bottom side of the mounting base by rotating the fixing on one of the screws by the hidden face of the mounting base, such as a countertop, up to a predetermined angle

Next, the other must be screwed screw in the other threaded hole of the fixing. It is preferable that the other threaded hole of the fastener is located in such a way so that the other screw can easily fit into the hole screwed.

The adapter assembly may also include a positioning means to align the other threaded hole of the fixing and the other screw. With this structure, the other screw can be easily screwed into the other threaded hole of fixing.

The fixation may be provided with a stop that comes in contact with the other screw in a direction in which the fixing rotates on the first screw and the stopper can constitute the means of positioning. With this structure, the alignment can be done easily by turning the fixation to put the stopper in contact with the other screw.

The stop can be an elastic clip that fits elastically with the other screw. This structure prevents the fixation deviates due to rebound when the stop enters contact with the other screw due to the rotation of the fixing, and it also prevents the fixing from separating from the other screw due to the strike between the other screw and the stop when the other is screwed screw in the threaded hole with the stop in contact with the another screw

The stop can be made of magnet or can hold a magnet to the top, and the other screw is made of a magnetic material to avoid oscillations between the other screw and the top thanks to the magnetic absorption between both.

The adapter may be provided with a stop that extend down from the bottom of it and enter contact with the fixing in the direction in which the fixing on one of the screws to position the fixing, and the stop can constitute the positioning means. Also with this structure can be positioned fixing in position adequate.

The adapter assembly may also include a medium resistant for the fixing to rotate together with the screw when the screw screwed in the threaded hole of the fixation. Therefore, the fixation can be turned by turning simply screw on the side of the mounting surface of the mounting base and the fixation can easily be placed in a default position

A coating material or a fixator on the surface of the screw or threaded hole to increase the friction force and this may constitute the medium resistant A nut to prevent the fall of the fixation which is screwed into the lower end of the screw can serve as lock nut The lock nut can be the means resistant.

The adapter can be provided with a tab formed over the entire periphery of it by the side of the face so that it sits on the mounting base. Therefore you can ensure a large contact area between the adapter and the mounting surface, that is a large sealing area.

Description of preferred embodiments

Embodiments of the present invention with reference to the attached drawings.

Figure 1 shows a tap attached to a countertop (mounting base). In this figure, the number 10 designates the tap as an item and the number 12 designates the countertop.

The tap 10 comprises a tap body 14 located perpendicularly on the countertop 12, a spout 18 that is extends from the tap body 14 and that has a mouth 16 by which the water comes out, and a control lever 20 positioned so pivoting on an upper part of the tap body 14.

The lower end of the spout 18 is attached to a cylindrical part 22 which is rotatably mounted on the tap body 14. The spout 18 can pivot laterally together with the cylindrical part 22.

The tap body 14 has a stop (no represented) that defines the limit of the pivoting displacement side of the spout 18, so that the spout 18 can pivot laterally within an angular range defined by the stop.

The faucet 10 is attached to the countertop 12 through of a hole 24 made in the countertop 12.

The number 26 designates supply tubes to supply water and hot water to tap 10. The end top of the supply tubes 26 is connected to the body 14 of the tap through the hole 24.

As shown in Figure 2, tap 10 is mounted on the countertop 12 by means of an adapter assembly 28.

Figures 4A, 4B, 5, 6, 7 and 8 show specifically the structure of the adapter assembly 28.

The adapter assembly 28 comprises an adapter 30, a fastener 32 and a pair of screws 34, 36, as shown in Figures 4A, 4B.

The adapter 30 to be seated on the side top (mounting surface) of countertop 12 is the semi-piece upper of a mechanism to tighten the countertop and has generically a cylindrical shape. The adapter 30 is provided of an annular flange 38 formed on the outer periphery by the countertop side 12. Tab 38 makes a tight contact with the top of the countertop 12 by means of an element of 40 ring type sealing.

The adapter 30 has an annular protrusion 42 that projects down from the bottom of the adapter 30. The sealing element 40 is attached to the bottom of the adapter 30 in such a way that it fits over the annular protuberance 42

The adapter 30 is provided with grooves upper and lower annular 44 formed on the outer periphery of the same and in which annular elements of tightness 46, respectively. The adapter 30 makes a contact hermetic with the inner periphery of a cylindrical part 48 (Figure 2), which will be described later, and which is located in the lower end of the tap body 14, by means of the elements sealing rings.

The adapter 30 is provided with 50 semicircular bulges (two bulges in this realization) projected inwards and formed on the surface internal of it (Figure 8). Each bulge 50 is provided of a through hole 52 that penetrates vertically in the protuberance, as shown in Figures 6 and 8, and in which screw 34, 36 is introduced.

The adapter 30 is also provided with four 54 semicircular projections formed on the inner surface in such a way that projections 54 are separated by predetermined distances in circumferential direction (Figure 8). The adapter 30 has guiding protrusions 56 that project down from the bottom of the respective projections 54 to a level lower than the bottom of the flange 38.

The guiding protuberances 56 fit in the hole 24 with a given tolerance to guide the adapter 30 and mount the adapter 30 through the hole on the countertop 12 24.

The guiding protuberances 56 facilitate the placing adapter 30 in the proper position. I mean, I know can properly place the bottom of adapter 30 in contact with the top surface of the countertop 12, around the hole 24, preventing the adapter 30 from being in a position displaced with respect to the hole 24. This ensures a large contact area between adapter 30 and overhead 12, is say, a large sealing area.

On the bottom side of the countertop 12 is placed a fastener 32 as shown in Figures 2 and 4 for sandwich the countertop 12 between it and the adapter 30. The fixing 32 is provided with a plurality of teeth 58 formed on the upper surface along the entire periphery of the fastener 32. These teeth 58 press firmly on the underside of the countertop 12.

Fixation 32 generally has a curved configuration, more particularly a configuration of circular arc, whose length in the circumferential direction is greater than half the circumference of the hole 24.

Fixing 32 has projections 60, 62 that they project inwards and are formed on the inner surface of it in positions close to the ends circumferential Each of the projections 60, 62 is provided with a threaded hole 64 that penetrates vertically in the projection 60, 62 as shown in Figure 6. Screws 34, 36 are screwed into the respective threaded holes 64 of the projections 60, 62.

A projection 62 is formed in a position lower than the other projection 60 and is provided with a clip elastic 66 semicircular (contact part) as a means of alignment located on the upper surface of the projection. The Elastic clip 66 is concentric with threaded hole 64.

Screw 34 is longer than screw 36, with a fixed difference, whereby screw 34 is screwed into threaded hole 64 and lower end of screw 34 protrudes from the bottom of fastener 32 until screw 36 reach threaded hole 64 of fastener 32. Screw a nut 68 (Figure 6, Figure 11) at the lower end of the screw 34 projecting down from the bottom of the fastener 32

Nut 68 prevents fixing 32 from falling. Nut 68 also serves as a lock nut (element resistant) to rotate the fastener 32 by rotating the screw 34 before installation on countertop 12.

The procedure to fix the adapter assembly 28 of this embodiment on the countertop 12 will be described with reference to Figures 9 to 11.

As shown in Figure 9A, screw 34 longer is introduced through a through hole 52 of the adapter 30 and it is screwed into the threaded hole 64 of the fastener 32 until the lower end of the screw 34 protrudes from the bottom of the fixing 32. Nut 68 is screwed into the lower end screw 34 protrusion and fully tightened, whereby the nut 68 serves as a lock nut so that the fixing 32 rotates together with screw 34.

The fixing 32 is then turned on the screw 34 such that the free end of the fastener 32 protrudes radially from adapter 30 as shown in the Figure 9A Next, the adapter assembly 28 is tilted as shown in Figure 9B. In this state, the free end of fixing 32 through hole 24.

In this way, the fixing 32 can be easily inserted through hole 24 and located on the side concealed countertop 12.

Next, the short screw 36 is introduced in the other through hole 52. The bottom of the screw 36 protrudes down from the bottom of the adapter 30.

After the previous step, screw 34 is turned so that the fixing 32 rotates together with the screw 34 on the side Hidden from countertop 12 as shown in Figure 10.

When the fixture 32 has turned to a position on the periphery of the hole 24 shown in the Figure 10 using an arrow A, the elastic clip 66 fits elastically in the short screw 36, whereby the hole threaded 64 formed in projection 62 is coaxially located with screw 36.

Then screw 36 is screwed into the hole threaded 64, which is now faced with screw 36 as shown in Figure 11. When tightening screws 34 and 36 on the threaded holes 64, the fixing 32 rises from the position shown in Figure 11 until it comes into contact with the side  bottom of countertop 12 around hole 24 (Figure 7).

Tightening screws 34 and 36, countertop 12 is tightly tightened vertically between the adapter 30 and the fixing 32. In this way, the adapter assembly 28 is subject to the countertop 12.

In this state, the guiding protuberances 56 of adapter 30 are fitted in hole 24 with a slack determined, and the underside of tab 38 of the adapter 30 is in tight contact with the top of the countertop 12 through the sealing ring element 40 with a determined pressure Figure 7 shows this state.

Once screw 34 is fully screwed, the nut 68 stops acting as a lock nut and, from then, it serves only as an element that prevents the fall of fixation 32, as shown in Figure 7.

Once the adapter assembly 28 is mounted on the countertop 12 as mentioned above, the part is mounted cylindrical 48 of the lower end of the body 14 of the tap on the adapter 30, as shown in Figure 3, and screw a clamping screw 70 in a threaded hole 78 of the adapter 30 through an opening 74 of a coating ring 72, which it is rotatably placed around the tap body, and of an opening 76 of the cylindrical part 48. Therefore, the body 14 of the tap and the adapter 30 are fixedly connected to each other so they don't turn on each other.

Then the cover ring is turned 72 to hide the opening 76 of the cylindrical part 48 and the clamping screw 70 of the tap body 14. The opening 74 of cover ring 72 is capped with a surface plug 80 (Figure 2).

Since in this embodiment the fixing 32 is attach to adapter 30 by screwing the two screws 34, 36, it is not produces no movement in the rotational direction of the joint 32 with respect to the adapter 30 although an external force is exerted Rotational on tap 10 after installation. Great resistance to rotation can be achieved, solving  thus the problem that the tap 10 is loosened on the countertop 12 in the rotational direction and that the fixation 32 goes out through the hole 24.

The fixture 32 is in the form of a circular arc that extends over the periphery of the hole 24 and that has a large circumferential length so that the fixing 32 can do contact with the underside of countertop 12 over an area extensive in the circumferential direction, thus increasing the force of  tighten the fixing 32 and the adapter 30 on the countertop 12.

According to this structure, a single fixation 32 is enough to fix the adapter assembly 28, thus reducing the number of pieces.

Since the fixation 32 is long in the circumferential direction, adapter 30 and fixing 32 are connected by screws 34, 36 in spaced positions each other in the circumferential direction, thus increasing the distortion resistance of adapter 30 and fixing 32 in rotational direction and thus effectively increasing the resistance in rotational direction

Since the fixation 32 has an arc shape circular corresponding to the shape of the hole 24, the fixing 32 does not interfere with the introduction of the supply tubes 26 or similar in hole 24, thus leaving a large space in the hole 24.

In this embodiment the elastic clip 66 is provided as a centering element to place the fixing on the proper place, so that screw 36 and threaded hole 64 are coaxially located with each other, thereby simple rotation of the fixing 32 can be concentrically located screw 36 and threaded hole 64 for easy screwing screw 36 in threaded hole 64.

Since the elastic clip 66 fits elastically on screw 36 to prevent displacement of the fixing 32, once the fixing 32 is placed, the fixing no goes out of place when screw 36 is tightened in the hole threaded 64 after fixing the fixing 32 by means of a rotation of it. Therefore, screw 36 can be screwed in the threaded hole 64 while maintaining the fastener 32 in the proper site.

In the structure of this embodiment, since the nut 68 acts as a lock nut, the fixing 32 together with screw 34 simply turning the screw 34 after the fastener 32 has been inserted through the hole 24. Fixing 32 can rotate smoothly on the side hidden from the countertop 12 until the elastic clip 66 fits in the screw 36.

One of the means for fixing 32 to rotate with screw 34 it is a coating material or a fixative that be applied on the surface of screw 34 or hole threaded 64 to increase the friction force.

In this embodiment, tab 38 is located over the entire circumferential length of the adapter 30 on the side of countertop 12, thus ensuring a large area of contact, that is to say a large sealing zone, between the adapter 30 and countertop surface 12.

Figure 12 shows another embodiment of the present invention Fixing 32 has a stop 90 in the form of erect circular arc over a part of the periphery of the hole threaded 64. Fixing 32 is located in the rotational direction because the stop 90 comes into contact with the screw 36.

The screw 36 is made of a material magnetic and the stop 90 is made of magnet, or a magnet is held to stop 90, to avoid misalignment between screw 36 and the stop 90 thanks to the magnetic absorption between screw 36 and the magnet. In Figure 12, an arrow A shows the direction and margin of rotation of the fixing 32.

Figure 13 shows another embodiment of the present invention The adapter 30 is provided with a stopper 82 in rectangular plate shape that extends downward from the bottom of it. Screw 36 and threaded hole 64 of the fixation 32 are coaxially placed with each other because the stopper 82 contacts the internal surface of the fastener 32

Figures 14A, 14B show another embodiment of The present invention. A fastener 92 is in the form of a plate rectangular, that is rectangular and straight, whose length in longitudinal direction is larger than the hole diameter 24.

Fixing 92 is placed across the diameter of the hole 24 on the hidden side of the countertop 12. The screws 34, 36 through holes 52 of adapter 30, placed on top of countertop 12, and they are screwed into a pair of threaded holes 64, 64 made in fixing 92 so that the countertop 12 is pressed vertically between the adapter 30 and fixing 92 to hold the adapter set 28 on the countertop 12.

Also in this embodiment, since the fixing 92 and adapter 30 are connected to each other by the two screws 34, 36, great strength can be obtained in the rotational direction

Figures 15A, 15B show another embodiment more of the present invention.

The adapter 30 has protrusions 50 each of them has a through hole 94 whose section horizontal is a torn hole, so that a screw 34, 36 introduced through the hole 94 can move in the direction horizontal inside the through hole 94.

Fixation 96 generally has a shape rectangular and straight, as in the embodiment of Figure 14. Fixing 96 comprises an intermediate part 98 and two parts extreme 100, 100 in the longitudinal direction that are formed regardless of intermediate part 98.

The end portions 100, 100 are arranged such that they slide in the longitudinal direction with respect to the intermediate part 98. That is, in this embodiment the fixing 96 is retractable in the longitudinal direction. The degree of retraction of fixation 92 is set such that the maximum size of the fixing 96 in the longitudinal direction, that is in the state in the which ends are totally separated from each other, is larger than the diameter of hole 24, while the size minimum of fixing 96 in the longitudinal direction, that is in the state in which the ends 100, 100 are in the most position close to each other, is smaller than the diameter of the hole 24.

Each of the end parts 100, 100 is provided with a guide face 102 inclined upwards and towards the extreme.

An example will be described in Figures 16 and 17 of procedure to fix the adapter assembly 28 of this realization on the countertop 12.

First, fixation 96 is adjusted to maximum size as shown in drawing (I) of Figure 16 and, in this state is placed next to hole 24 in order to insert fastener 96 through hole 24.

The guide faces 102 come into contact with the periphery of hole 24 as shown in drawing (II) of Figure 16. In this state a downward force is exerted on the fixing 96, fixing 96 automatically shortens to shrink enough to be able to enter through hole 24 because the guide faces 102 help to shorten the fixing 96 as shown in drawing (III) of Figure 16. That is, the two end parts 100, 100 slide in the direction of approach each other.

As the end portions 100, 100 slide, the screws 34, 36 approach each other moving through the through holes 94.

After the states of the drawings (II) and (III) of Figure 16, fixation 96 is introduced into the hole 24. Then fixation 96 is lengthened as shown in drawing (IV) of Figure 17

Fixing 96 can be extended by exerting on the bolts 34, 36 a force in the direction of the arrows B of the drawing (IV) of Figure 17.
