Thus installation of the pedestal 3 and fitting of the tap body 1 can be performed by operation to be made only from the front of the mounting surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet provided in, for example, a counter of a sink or a washbasin of a vanity, and more particularly to a fixing structure for facilitating a fixing work of a faucet body.

[0002]

2. Description of the Related Art For example, when fixing a hot and cold water mixing tap to a counter of a sink, a water supply pipe and a sleeve with a male screw that encloses the hot water supply pipe are provided at the lower end of the main body, and this sleeve is inserted into the mounting port of the counter and A conventional structure is one in which a nut is screwed into the sleeve from the lower side and the counter is pressed tightly to fix it.

In such a fixing structure, when the nut is screwed into the sleeve from the lower side of the counter, the worker goes into the cabinet. For this reason, when fixing the faucet body, it is necessary to hold the faucet body above the counter in order to correct the posture after the fixation. Therefore, it is a work of screwing the nut in the cabinet and a work of holding the faucet body, and the construction is performed by at least two workers.

In order to save the labor of such a work, the faucet body can be fixed only by handling it from the upper surface side of the counter, for example, an actual flat panel 5-.
There is one described in Japanese Patent No. 30261.

This is equipped with an adapter for fixing the faucet body by simply inserting it from above the counter, and this adapter has a plurality of elastically deformable mounts that are bent in a dogleg shape and project downward. It is provided with a piece.
The mounting piece is inserted into the mounting opening of the counter by utilizing its contraction deformation, and the adapter is fixed to the counter by the engagement with the mounting piece between the lower surface of the counter and the counter.
Then, when the male screw for mounting provided at the lower end of the faucet body is inserted into the adapter, the lower end of the mounting piece will bite into the male screw, and the elastic reaction force of the mounting piece will be used for the faucet body. The faucet body is fixed to the counter by applying downward restraining force.

Further, as a means for simplifying the work of fixing the faucet, there is a faucet fixing structure described in Japanese Utility Model Publication No. 3-22369.

In this, a mounting plate for fixing is provided at the mounting port of the counter so as to project upward from the counter surface, and is provided in advance so as to be included in the lower end portion of the faucet body. Then, the faucet body is fixed to the counter through the mounting plate by covering the faucet body with the mounting plate and screwing fixing screws from the peripheral wall to the mounting plate.

[0008]

[Problems to be Solved by the Invention]
In the configuration described in Japanese Patent No. 30261, the male screw for mounting the faucet body is constrained by a plurality of points that engage with the lower end of the mounting piece. In this case, the engaging postures of the respective mounting pieces that are in contact with the valleys of the male screws are not necessarily uniform, and the restraining force of the respective mounting pieces tends to vary. That is, since the operation of inserting the male screw-forming cylinder into the lower end of the mounting piece arranged in an arc shape, it is not possible to artificially correct the engagement between the mounting piece and the male screw. Therefore, the engagement force cannot be adjusted.

Due to such construction restrictions, it is possible to increase the restraining force by increasing the number of attachment pieces. However, even in this case, the equalization of the restraint force by each attachment piece is not achieved.

Further, in the one disclosed in Japanese Utility Model Publication No. 3-22369, the fixing screw appears on the surface of the lower end portion of the faucet body, so that the appearance is liable to be impaired and the faucet body design. Will also be constrained.

When the faucet body is attached to the counter, it is usually located near the sink and on the back side thereof. For this reason, the layout is such that the back guard of the counter approaches immediately behind the faucet body. In this case, for example, if a screw is screwed on the back side of the faucet body, the screwing work using a driver cannot be performed, and the work using a special tool is forced, which also affects the workability.

As described above, in the conventional fixing structure, the faucet body can be fixed only from the upper side of its mounting surface, but the strength for stable support is insufficient and the faucet body is loose. May cause the Also, for those that require screwing, even if a cosmetic cover for hiding exposed screws is provided, from the viewpoint of the current state of the faucet, not only the function but also the design has become important recently. , The effect on appearance cannot be ignored.

An object to be solved in the present invention is to provide a fixing structure in which the faucet body can be constructed more easily and can be favorably constructed without causing a lack of strength.

[0014]

According to the present invention, there are provided a fixed pedestal which is arranged in accordance with a mounting opening formed on a mounting surface of a faucet body, a retainer which is located on the back side of the mounting surface, and these fixed pedestals. A fastening means for fastening the retainer to the mounting surface from the front side, and the retainer can pass through the mounting opening depending on its posture and can hit the back surface around the opening edge of the mounting opening. The fixing pedestal can be fixed by converting the fastening force of the fastening means into a clamping force between the front and back surfaces of the mounting surface by the fixing pedestal itself and the retainer, and further fixing the fixed pedestal to the fixed pedestal. It is characterized by connecting the faucet body.

The fastening means and the retainer may be connected to each other with a degree of freedom of a posture allowing passage of the retainer with respect to the mounting port, and the fastening means restrains the fixed base and the retainer from each other. It can be configured as a bolt and a nut that are matched with each other.

The fastening means comprises a bolt penetrating the fixed pedestal and the retainer from the front side of the mounting surface and a nut screwed to the bolt from the rear side of the retainer. The retainer is around the bolt and with respect to its axis. In addition to being externally inserted so as to be tiltable, it can be shaped such that it can be engaged with the back surface side of the mounting surface when it is in a posture substantially orthogonal to the bolt, and that the mounting port can be inserted in a tilted posture.

In this case, between the retainer and the fixed base,
A rotation stopper that is inserted into these members and regulates mutual rotation can be interposed, and the nut and the retainer can be connected by a concave-convex engagement that regulates mutual rotation. Alternatively, the fixed pedestal and the retainer may be provided with packings on the surfaces abutting the front surface and the back surface of the mounting surface, respectively.

Further, the fixed pedestal may have a notch in which the bolt can be inserted and removed from the portion through which the bolt is inserted toward the outer edge.

In this case, a bulky bush projecting above the mounting surface is attached to the mounting port, and a fixed pedestal is disposed in contact with the surface side of the bush so that the bush is mounted between the mounting surface and the fixed pedestal. A packing may be interposed between each.

Furthermore, the fixed pedestal may be provided with a male screw on the outer peripheral surface thereof, and the faucet body may be rotatably provided with a cap nut type fastening nut that is screwed into the male screw.

In this case, the fixed pedestal and the faucet body may be constrained by a concavo-convex engagement that regulates the rotation of these around the core. And this concave and convex engagement is
The engaging pedestal is composed of an engaging protrusion protruding in the direction of joining the fixed base and the faucet body and an engaging groove for receiving the engaging protrusion. The engaging projection, the engaging groove, the fastening nut, and the threaded portion of the fixed pedestal may have a positional relationship so that they can be screwed into the male screw.

[0022]

[Function] By inserting the retainer into the mounting opening and submerging it on the rear surface side of the mounting surface, and by fixing the fixed pedestal arranged around the mounting opening to the retainer by the fastening means, the retainer extends to the rear surface of the mounting surface. The fixed pedestal hits the surface and holds both the front and back sides. Therefore, by converting the fastening force of the fastening means into the holding force, the fixed pedestal is fixed to the mounting surface together with the retainer. By connecting and fixing the faucet body to the fixed pedestal, the faucet can be fixed only by an operation from the surface side of the mounting surface.

By connecting the fastening means and the retainer to each other with a degree of freedom of posture allowing passage of the retainer with respect to the mounting opening, the retainer can be incorporated below the mounting opening using the fastening means.

When a bolt to be inserted from the fixed pedestal side and a nut for receiving the rear surface of the retainer are used as the fastening means, the shape of the retainer when tilted obliquely with respect to the axis of the bolt and when the retainer is in the vertical posture is different from the mounting opening. If it is detachable and engageable with the back surface, it becomes possible to insert the retainer into the mounting port before fastening and to pinch and fix the retainer and the fastening base after fastening.

By making the nut and the retainer engage with each other such that they do not rotate together, if the bolt is turned while the retainer is abutting against the back side of the mounting surface, the bolt can quickly enter the nut, Fastening with bolts can be done without applying a tool. Further, if the retainer is provided with a packing at the portion which contacts the back surface of the mounting surface, not only the seal but also the rotation resistance can be utilized, and the bolt and the nut can be fastened more quickly. Further, by incorporating the rotation stopper between the retainer and the fixed pedestal, it is possible to prevent the retainer and the fixed pedestal from rotating together when strongly tightening the bolt and nut.

Further, if the fixing pedestal is provided with a notch so that the bolt can be pulled out and inserted from the side, the retainer can be mounted and clamped after being dropped into the mounting port, and the retainer on the back of the mounting port can be mounted. Adjustment of the position of the nut and the nut becomes easy.

Even if the notch is provided in the fixed pedestal, a bulky bush is inserted between the fixed pedestal and packing on both front and back surfaces of the bush so that a seal from the mounting surface to the mounting port side can be obtained. Reserved.

Further, a male screw is provided on the outer periphery of the fixed pedestal, and a cap nut type fastening nut rotatably provided on the water faucet body is screwed into the male screw. It is possible to rotate and fasten only the fastening nut while holding it at, and it becomes easy to set the posture of the faucet body. At this time, if the fixed pedestal and the faucet body side are restricted from each other by the engagement of the concave and convex portions, the positioning between the faucet body and the fixed pedestal is possible.

Further, if the concave-convex engagement is made by the engagement projection and the engagement groove and the cap nut and the fixed base start to be screwed after the engagement, the work is performed while rotating the cap nut. At the same time, the faucet body remains tightly restrained by the fixed pedestal, and construction can be performed with the faucet body in an appropriate posture.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an exploded perspective view of an essential part showing a water faucet fixing structure of the present invention, and FIG. 2 is a longitudinal sectional view of the essential part showing a fixed state.

In the figure, for example, the faucet body 1 is fixed directly above a mounting opening 51 opened in a counter 50 of a sink. As a part of the faucet body 1, a block 1a is inserted into and fixed to the inside of the faucet body 1, a supply pipe 1b such as a water supply pipe and a hot water supply pipe is connected to the block 1a, and a valve element incorporated in the block 1a is operated to discharge the water. Water or hot water can be discharged from the water pipe 1c.

The block 1 protruding from the lower end of the faucet body 1
On the outer periphery of a, a cap nut-shaped fastening nut 2 is incorporated so as to be rotatable with respect to the block 1a and to exert a restraining force toward the mounting surface side. Then, by fastening the fastening nut 2 to a fixing member previously attached to the counter 50 side, the faucet body 1 can be restrained and fixed to the counter 50 side via the block 1a. The fastening nut 2 is attached to the lower end of the block 1a.
A pair of downwardly projecting engagement projections 1d are provided at two locations that are opposed to each other in the radial direction in order to prevent co-rotation during the rotation operation.

As a member for fixing the faucet body 1 to the counter 50, a fixed pedestal 3 mounted on the upper surface of the counter 50, a retainer 4 located on the lower surface side of the counter 50, and the fixed pedestal 3 and the retainer 4 are connected to each other. A bolt 5 and a nut 6 are provided as fastening means.

FIG. 3 is a perspective view showing these members in an exploded manner, and FIG. 4 is a perspective view showing the constituent elements in a further exploded manner and explaining how to insert them into the mounting port 51.

The fixed pedestal 3 is a rim 3a having a thickened peripheral surface portion, and a male screw 3b screwed onto the female screw 2a of the fastening nut 2 is formed on the outer periphery of the rim 3a. The rim 3a is provided with an engagement groove 3c into which the engagement protrusion 1d provided on the block 1a of the faucet body 1 fits. Rim 3a
A through hole 3d for passing the bolt 5 is formed at an eccentric position surrounded by the supply pipe 1
A piping hole 3e for inserting c is provided.

The retainer 4 is formed by press-molding a metal plate. The retainer 4 has a notch 4a aligned with the pipe hole 3e of the fixed pedestal 3 and a recess 4b between the retainer 4 and the portion surrounded by the arcuate outer periphery. Further, a through hole 4c for the bolt 5 is formed in the concave portion 4b, and slits 4d are formed at two positions facing each other in the radial direction at the opening edge of the through hole 4c.

Here, the retainer 4 is allowed to pass through from the upper side in a posture inclined with respect to the mounting opening 51, and
When it is in a posture substantially orthogonal to the axis of the bolt 5, it is assumed to have a planar shape that abuts against the lower surface of the counter 50 and can hold the counter. That is, the inner diameter of the mounting opening 51 is a predetermined constant size, and the outer diameter of the portion where the retainer 4 forms an arc is larger than that of the mounting opening 51 so that the retainer 4 contacts the lower surface of the counter 50. Also increase. Therefore, for example, as shown in FIG. 4, the peninsula portions 4e and 4f each having a shape that surrounds the notch 4a and is narrowed toward the center of the retainer 4 are inclined vertically, and the retainer 4 is passed through the mounting opening 51. You can do it like this. In order to enable such an operation, the distance from the line segment, which passes through the center of the retainer 4 and is orthogonal to the center line between the peninsula portions 4e and 4f, to the tips of these peninsula portions 4e and 4f, is at least the retainer. It should be shorter than the radius of 4. This allows the retainer 4 to have the posture as described above, so that the retainer 4 is passed through the mounting opening 51 and the counter 5
0 can be located on the lower surface side.

The retainer 4 may have, for example, a rod-like shape that abuts the lower surface of the counter 50 after passing through the mounting opening 51, in addition to the substantially horseshoe-shaped planar shape as shown in the figure.

Further, since the fixed pedestal 3 and the retainer 4 are abutted and fixed on the upper surface and the lower surface of the counter 50, respectively, packings 8 and 9 are provided for sealing between these two surfaces and for preventing rotation. As shown in FIG. 4, the packing 8 provided on the bottom surface of the fixed pedestal 3 is an annular body and is previously integrated with the fixed pedestal 3 by an adhesive. Further, the packing 9 of the retainer 4 has a planar shape along the arc-shaped outer contour of the retainer 4, and is integrated by fitting a fitting groove 9a having a concave cross section toward the inner peripheral side around the retainer 4. Is.

Returning to FIG. 3, the bolt 5 is provided with a head 5a at the upper end thereof and a male screw 5b formed over almost the entire length. The outer diameter of the male screw 5b is smaller than the inner diameter of the through hole 4c of the retainer 4, so that the retainer 4 can freely take an oblique posture around the bolt 5.

A nut 6 screwed from the lower end of the bolt 5
The two projections 6a are provided on the upper end surface thereof at positions facing each other in the radial direction. These protrusions 6a are
It is formed so as to enter the slit 4d of the retainer 4.

Further, in order to prevent co-rotation when the fixed pedestal 3 and the retainer 4 are firmly fixed to the counter 50, a rotation stopper 10 as shown in FIG. 1 is provided. This detent 10 has a flange 10a formed at the upper end and a skirt 10b that fits tightly into the piping hole 3e of the fixed base 3 and projects downward. The skirt 10b is also fitted in the inner edge of the notch 4a of the retainer 4 in a fitted state. The inner edges of the piping hole 3e and the cutout 4a are formed into a substantially heart shape and the skirt 10b is formed.
By making the outer shell of the same in a similar manner, it is possible to provide a concave-convex engagement relationship in the shape of a heart, and the fixed pedestal 3 and the retainer 4 are integrally restrained around the core thereof via the skirt 10b.

In the above structure, the work of fixing the faucet body 1 to the counter 50 is performed as follows.

For the fixed pedestal 3 and the retainer 4 to which the packings 8 and 9 are integrally attached in advance, the bolt 5 and the nut 6 are attached.
3 are arranged as shown in FIG. 3, and the bolt 5 is passed through the through holes 3d and 4c to combine these parts into one group as shown in FIG. At this time, since the bolt 5 is smaller than the inner diameter of the through hole 4c, the retainer 4 can be tilted with respect to the axis of the bolt 5 as illustrated.

Here, as shown in FIG. 3, by tilting the retainer 4 so that the peninsulas 4e and 4f of the retainer 4 are up and down with respect to the mounting opening 51, the retainer 4 is inserted into the mounting opening 51 while countering. It can be made to sink into the lower surface side of 50. In addition, such a retainer 4 is shown in FIG.
The relationship between the inclination and the mounting port 51 is shown.

Then, the bolt 5 is pulled up, and the packing 9 of the retainer 4 is applied to the lower surface of the counter 50 by the nut 6 at the lower end of the bolt 5, and the bolt 5 is rotated in the tightening direction. At the time of this operation, the protrusion 6a of the nut 6 is retained by the retainer 4
So that it goes into the slit 4d. Thereby, the bolt 5 can be screwed into the nut 6 while the retainer 4 does not rotate by utilizing the sliding resistance caused by the packing 9 being applied to the lower surface of the counter 50.

By screwing the bolt 5 and the nut 6 as described above, these members can be fixed by pressing the upper and lower surfaces of the counter 50 with the fixed pedestal 3 and the retainer 4. Then, at the time of final tightening, the detent 10 shown in FIG. 1 is dropped into the notch 4a from the pipe hole 3e. As a result, the fixed base 3 and the retainer 4 are integrated in the rotation direction by the rotation stopper 10, so that the slip resistance of the retainer 4 is also transmitted to the fixed base 3. Therefore, even if the head 5a is strongly tightened and exerts an acting force in the direction of turning the fixed pedestal 3, the fixed pedestal 3 receives the restraining force of the retainer 4 and is prevented from rotating, so Co-rotation is prevented.

As described above, the counter 50 of the fixed pedestal 3
After the installation, the next work is to fix the faucet body 1 to the fixed pedestal 3. The block 1 of the faucet body 1
The supply pipe 1b is previously connected to a at the factory shipping stage, and this supply pipe 1b is connected to the pipe on the building side below the counter 50 after fixing the faucet body 1.

When the faucet body 1 is fixed by covering it on the fixed pedestal 2, the engaging protrusion 1d of the block 1a is made to fall into the engaging groove 3c of the fixed pedestal 3 so that the water around the core of the fixed pedestal 2 is removed. The rotation of the stopper body 1 is restricted. In addition, since the fixed pedestal 2 is firmly fixed to the counter 50 in a proper posture in such rotation regulation, the faucet body 1 at the time of tightening with the cap nut-shaped fastening nut 2 in the later work. Therefore, the faucet body 1 is positioned and fixed in the correct posture.

Further, when the faucet body 1 is put on the fixed base 2, the female screw 2a of the cap nut 2 is inserted into the engagement groove 3c and then the female screw 2a of the cap nut 2 is inserted into the male of the fixed base 3. Start screwing on the screw 3b. Such a relationship is possible by appropriately adjusting the protruding length of the engaging protrusion 1d, the depth of the engaging groove 3c, and the positional relationship between the female screw 2a and the male screw 3b. With this configuration, the faucet body 1 does not rotate when the cap nut 2 is screwed, and its posture can be adjusted to the fixed pedestal 3.

After that, the fastening nut 2 is screwed into the male screw 3b of the fixed pedestal 2, and a tool is hung on the fastening nut 2 to firmly tighten the cap nut 2 so that the cap nut 2 is blocked.
The lower end portion of the faucet is constrained to the fixed pedestal 3 side, and the faucet body 1 can be firmly fixed to the counter 50 as shown in FIG. After fixing the faucet body 1, the supply pipe 1b hanging from the lower end thereof to the lower side of the counter 50 is connected to the building side pipe. At the time of this work, if the length of the supply pipe 1b is set to an appropriate length, the worker can
You can finish with a simple piping work without going deep under.

In this way, the faucet body 1 is replaced by the counter 50.
When fixing to the counter, the counter 50 performs all the series of work from installation of the fixed pedestal 3 to connection and fixing of the faucet body 1.
It can be handled from above. Therefore, it is not necessary for an operator to enter the counter 50 and connect the counter 50, and even one operator can easily install the faucet body 1.

Since the upper and lower surfaces of the mounting port 51 are sealed by the packings 8 and 9, the counter 50
Water from the surface never flows into the cabinet.
Further, by sandwiching the upper and lower surfaces of the counter 50 by the elastically deformable packings 8 and 9, the counter 50
Even if the surface accuracy is poor, the faucet body 1 can be firmly fixed in a stable state by utilizing its elastic deformation, and the occurrence of rattling and the loosening of pipes can be effectively prevented. it can.

6 to 10 show an example of another fixing structure. The same members as those in the previous example are designated by common reference numerals, and detailed description thereof will be omitted.

In this example, the fixed pedestal 3 has through holes 3 formed therein.
Notch 3f is provided to open d to the outside and bolt 5
So that it can be inserted and removed from the notch 3f. Cutout 3
As shown in the plan view of the fixed pedestal 3 in FIG. 6, f is incised in a direction extending in the radial direction from the through hole 3d, and the upper half thereof also serves as an engagement groove into which the engagement protrusion 1d of the block 1a is inserted. The opening width of the notch 3f is slightly larger than the outer diameter of the bolt 5, and the engaging projection 1d provided on the block 1a is also sized so that it can be fitted tightly into this opening width.

Since the notch 3f is provided in the fixed pedestal 3, the notch 3f may serve as a passage for water to break the seal from the upper surface of the counter 50 to the mounting opening 51 side. Therefore, the bushes 11 and 2 as shown in FIG.
A seal structure is newly provided by the packings 12 and 13 of one sheet.

The bush 11 is made of synthetic resin, for example, and has a flange 11a formed at the upper end and a plurality of tongue pieces 11b provided below the flange 11a. The flange 11a has an outer diameter to be mounted around the opening edge of the mounting opening 51, and the tongue piece 1
1b is provided with a bulged portion 11c on the outer periphery of its lower end so that it can be elastically fitted into the mounting port 51.

The packing 12 is integrated with the upper surface of the flange 11a by an adhesive and receives the lower surface of the fixed pedestal 3 to seal the portion other than the notch 3f. Further, the packing 13 arranged below is fitted and fixed around the tongue piece 11b to seal the upper surface of the counter 50.

The fixing of the fixed base 3 to the counter 50 is
Prior to this, the bush 11 and the members of the packings 12 and 13 integrated with the bush 11 are fitted into the mounting opening 51. This fixing is performed by inserting the tongue piece 11b of the bush 11 into the mounting opening 51 and utilizing the elastic deformation of the tongue piece 11b and the elastic reaction of the bulging bush 11c to the inner peripheral wall of the mounting opening 51.

Next, it is assumed that only the bolt 5, the nut 6 and the retainer 4 are combined, and the retainer 4 is inserted into the mounting opening 51 in an inclined posture as in the previous example.
At this time, unlike the previous example, since the work is performed without connecting the fixing pedestals 3 to the bolts 5, the work of inserting the retainer 4 into the mounting opening 51 with the diagonal orientation becomes easy. Further, after the insertion, the fingertips may be hooked on the retainer 4 from the mounting opening 51 so that the protrusion 6a of the nut 6 is inserted into the slit 4d of the retainer 4.

When the retainer 4 is completely inserted into the mounting port 51, the fixing base 3 is moved from the side of the bolt 6 so that the bolt 6 can pass through the notch 3f. As a result, the fixed pedestal 3 can be joined to the bolt 6 as shown in FIG. 8, and thereafter the fixed pedestal 3 can be fixed to the counter 50 in exactly the same manner as the previous example.

After the installation of the fixed pedestal 3, the supply pipe 1b
Is connected to the block 1a side, and then the fastening nut 2 is screwed into the male screw 3b of the fixed base 3 to fix the faucet body 1 to the counter 50 as shown in FIG.

Here, since the packing 13 provided on the lower surface of the bush 11 seals the upper surface of the counter 50, invasion of water along the surface of the counter 50 to the mounting port 51 side is prevented. Moreover, since the packing 12 arranged on the upper surface of the bush 11 is higher in level than the upper surface of the counter 50 by the amount of the bulk of the flange 11a, even if a large amount of water is drained to the counter 50, the seal by the packing 12 is secured. It Therefore, even if the fixed pedestal 3 is provided with the notch 3f, these packings 12 and 13 prevent water leakage from the surface of the counter 50 to the mounting port 51 side.

[0064]

According to the present invention, the fixed pedestal itself can be fixed to the mounting surface by sandwiching the front and back surfaces of the mounting surface by the fastening force of the fastening means with the fixed pedestal and the retainer. The pedestal can be firmly attached, and the faucet body can be stably fixed via this fixed pedestal. Since all of these operations can be performed from the surface side of the mounting surface, even a single worker can perform simple construction.

If the faucet body is connected by a cap nut-shaped fastening nut mounted on the faucet body so as to wrap the fixed pedestal, parts such as screws are not exposed on the surface of the faucet body and the appearance is impaired. Nothing.
