DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device provided with a fixing device to which various articles are fixed, and more particularly, to a fixing device which can be firmly installed only from a surface side of a mounting hole formed in a mounting destination. The present invention relates to a fixing device that can be attached.

2. Description of the Related Art When mounting various articles on a wall or ceiling which is difficult to install from the inside, for example, when installing a faucet on a sink or a sink, it is necessary to fix the faucet from below the sink or the sink. Construction must be done. Since such work is performed in a narrow and dark place, workability is poor,
Problems such as the necessity of special tools and the long mounting time occur.

Therefore, as a countermeasure against the above, after inserting a holding plate connected to the faucet fixing device from above with a bolt into the faucet mounting hole opened in the top plate of the sink, and tightening the bolt to secure the faucet. By sandwiching the plate between the faucet fixture and the holding plate,
Several water faucet mounting structures have been proposed that enable a water faucet to be mounted on a water faucet fixture fixed to a sink only by operation from above.

[0004] As one of the proposals, after inserting a holding plate (retainer) integrally connected with an annular faucet fixing device (fixing pedestal) and a bolt into a faucet mounting hole formed in a top plate while tilting the same, Tighten the bolts and fix the faucet fixing device to the top plate by sandwiching the top plate between the holding plate arranged on the back side of the top plate and the faucet fixing device arranged on the front surface side of the top plate A faucet mounting structure has been proposed (Japanese Unexamined Patent Publication No. Hei 8-93012).
issue).

In this water faucet mounting structure, a press plate is inserted into a water faucet mounting hole in an inclined position, and then a bolt for engaging a slit formed in the press plate with a projection provided on a nut is engaged. The faucet fixture is fixed to the top plate by an operation from above by pulling up and then tightening the bolt to sandwich the top plate between the faucet fixture and the holding plate.

[0006]

However, in the above conventional method, in order to prevent the bolt and the nut from rotating together,
The bolts are tightened into the nuts by using the sliding resistance by applying the presser plate to the back of the top plate so that the presser plate integrated with the nut is not rotated. Is required to be engaged. In addition, in order to check the engagement between the holding plate and the bolt, it is necessary to look into the faucet mounting hole from above and check the position of the holding plate.

Here, the holding plate and the bolt are engaged in advance in the upper part of the faucet mounting hole, and the bolt is inclined when inserted into the faucet mounting hole, so that the holding plate is in the inclined posture. A method of inserting the plug into the plug mounting hole is also conceivable. However, since the faucet fixing bracket is disposed above the holding plate, if the bolt is too short, the faucet fixing bracket will hit the surface of the top plate, making insertion difficult. Thus, for example, 30
In order to smoothly insert the holding plate into the faucet mounting hole formed on the top plate having a thickness of mm, it is necessary to lengthen the bolt, and the number of tightening of the bolt after insertion increases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to enable a fixing device to be attached to a mounting destination with good workability, and to make the fixing device, and hence the article, strong for a long period of time. To be fixed to the

[0009]

According to the present invention, there is provided a fixing device comprising: a fixing member to which various articles are fixed; and a holding plate for sandwiching an attachment with the fixing member, wherein the fixing member is rotatably inserted through the fixing member. The bolt is screwed to the holding plate, and the bolt is eccentrically arranged from the center of the fixing tool, and an elastic member is provided between the fixing tool and the holding plate. It is characterized by. In such a configuration, it is preferable that the bolt is disposed eccentrically from the center of the holding plate. Further, as the elastic member, it is possible to pivot the holding plate so as to be able to retreat from the position facing the fixture with the bolt as the central axis, and to automatically return the holding plate to the original facing position from the retracted state. That is, a member which can be used, that is, a piano wire, a coil spring, or the like having good deformability and strong restoring force is preferably used.

[0010] The mounting method of the fixing device according to the present invention is a method of inserting the fixing device into a mounting hole having a diameter smaller than an outer diameter of the holding plate and mounting the holding device on a predetermined mounting destination. Turning the holding plate to retreat from the position facing the fixing tool, and holding the retracted state while tilting the bolt with respect to the axis of the mounting hole, Step of inserting into the mounting hole, in a state where the holding plate is inserted into the mounting hole,
Returning the pressing plate to a position facing the fixing tool by a restoring action of the elastic member.

[0011] With the above configuration, when inserting into the mounting hole,
By turning the holding plate, the holding plate can be retracted from the position facing the fixing device.When inserting the holding plate while tilting the bolt with respect to the axis of the mounting hole, the fixing device is used. The holding plate can be easily inserted without causing interference with the mounting destination. Also, even if the distance between the fixing tool and the holding plate is short, interference between the fixing tool and the mounting destination can be avoided, so that the bolt length can be shortened and the number of tightening of the bolt after insertion is reduced. Becomes possible.

In addition, after the insertion into the mounting hole, the holding plate is automatically returned to the position facing the fixture by the restoring action of the elastic member, so that the position of the screw hole can be confirmed by looking through the upper part of the mounting hole. It becomes unnecessary and workability is improved. Further, since the screw holes are formed directly in the holding plate, the operation of pulling up the bolt and engaging with the nut as in the above-described conventional example is not required, and the workability is further improved.

Further, in the above construction, if the fixing tool and the presser plate are connected by two bolts which are spaced apart from each other, the burrs when the mounting holes are made are formed on the back surface of the mounting destination. Even if it remains on the side or the periphery of the mounting hole is partially missing, the mounting destination can be firmly tightened by the fixing tool and the holding plate.

[0014] In the above structure, one of the screw holes screwed with the two bolts, which is screwed with the bolt far from the elastic member, may have a taper having a larger diameter than the bolt. If the portion is formed, the bolt can be guided to the screw hole by the guide function of the tapered portion even when the position of the holding plate is not completely restored and the position facing the fixing tool is slightly shifted. Therefore, the bolt can be easily and reliably tightened.

Further, in the above construction, if the article fixed to the fixture is a faucet, the faucet must be installed from below such as a sink or a sink. Even so, it is possible to easily and firmly attach the fixing device only by installing from above. Therefore, the faucet fixed to the fixture is also firmly fixed for a long time.

[0016]

FIG. 1 is an overall configuration diagram showing a water faucet fixing device according to an embodiment of the present invention. The faucet fixing device includes a faucet fixing bracket (fixing tool) 1 for fixing a faucet, a holding plate 2 for sandwiching a top plate such as a sink or a wash basin together with the faucet fixing bracket 1, and a faucet fixing. Metal fitting 1 and holding plate 2
And a support pin (elastic member) 5 having resilience and provided between the faucet fixing bracket 1 and the holding plate 2.

On the inner peripheral side of the annular faucet fixing bracket 1, a bolt support portion 1 which is disposed so as to be opposed to and spaced apart in the diametrical direction.
1 and 12 and a support pin support portion 13 disposed in circumscribed relation with one of the bolt support portions 11 are provided. Bolt holes 3 </ b> A, 3 </ b> A, which are rotatably inserted into the bolt support portions 11, 12 in a state where the upper ends of the bolts 3, 4 are retained.
4A are formed, and the support pin support portion 13 includes:
A support pin hole 5A into which the upper end of the support pin 5 is inserted and fixed is formed.

On the other hand, two screw holes 3B and 4B into which the bolts 3 and 4 are screwed and the lower end of the support pin 5 are loosely fitted to the holding plate 2 having a substantially arc shape in plan view so as to be vertically movable. A support pin hole 5B is formed. These screw holes 3B,
4B and the support pin hole 5B are formed corresponding to the bolt holes 3A, 4A and the support pin hole 5A on the faucet fixing bracket 1 side, respectively.

The faucet fixing bracket 1 and the holding plate 2 are inserted into the bolt holes 3A, 4A of the faucet fixing bracket 1 while the lower end of the support pin 5 is passed through the supporting pin hole 5B of the holding plate 2. 3 and 4, screw holes 3B of the holding plate 2
By screwing into 4B, they are arranged facing each other and separated.
At this time, the bolts 3 and 4 are connected to the center O of the faucet fixing bracket 1.
The support pins 5 are disposed eccentrically from the center O2 of the holding plate 2 and the holding plate 2, and in the vicinity of one of the bolts 3, the support pin 5 is installed between the faucet fixing bracket 1 and the holding plate 2.

Here, the center O1 of the faucet fixing bracket 1 according to the present embodiment refers to the radial center of the faucet fixing bracket 1 forming an annular shape, and the center O2 of the holding plate 2 is a circle. The center point of the center line along the circumferential direction of the arc-shaped presser plate 2 is defined. Also, the bolt 3 closer to the support pin 5,
In other words, a retaining ring 6 for preventing the holding plate 2 from dropping is attached to the tip of the bolt 3 serving as a central axis when the holding plate 2 is turned, after being screwed into the screw hole 3B. Is preferred. As the support pin 5, for example, a piano wire, a coil spring, or the like having good deformability and strong restoring force is used.

Next, a procedure for attaching the faucet fixing device having the above-described configuration to the top plate 21 such as a sink or a sink will be described. In addition, it is assumed that a water faucet mounting hole 22 having a smaller diameter than the water faucet fixing bracket 1 and the holding plate 2 is formed in the top plate 21 as a water faucet mounting hole in advance. Therefore, the holding plate 2
Cannot be inserted into the faucet mounting hole 22 while being kept parallel to the top plate 21.

In order to insert the holding plate 2 of the faucet fixing device into the faucet mounting hole 22, first, as shown in FIG. 2, only the bolt 3 which is located near the support pin 5 is used. The faucet fixing bracket 1 and the presser plate 2 are connected so as to be opposed to and separated from each other. Next, as shown in FIG. 3, the holding plate 2 is turned in parallel with the faucet fixing bracket 1 around the bolt 3 as a central axis. That is, the presser plate 2 is turned in the same plane.

At this time, since the support pin 5 allows its own torsion due to its elasticity, the holding plate 2 is fixed to the faucet fixing bracket with the bolt 3 inserted eccentrically from the center O1 of the faucet fixing bracket 1 as a central axis. 1 withdraws from the position facing 1. In this case, in order to most effectively avoid interference between the holding plate 2 and the top plate 21 at the time of insertion, the holding plate 2 is turned 90 degrees with reference to the original position in FIG. Next, as shown in FIG. 4, the holding plate 2 is inserted into the faucet mounting hole 22 while the bolt 5 is inclined with respect to the axis of the faucet mounting hole 22 while maintaining the retracting posture of the pressing plate 2.

Then, in the case of FIG. 4, there is no faucet fixing bracket 1 at the position facing the holding plate 2 as shown in FIG. Only the holding plate 2 can be easily inserted into the faucet mounting hole 22 without hitting the holding plate 21. In particular, in the present embodiment, the bolts 3 and 4 are connected to the center O1 of the faucet fixing bracket 1 and the center O1,
By eccentricity from O2, it is possible to retreat the holding plate 2 largely from the position facing the faucet fixing bracket 1, so that the work of inserting into the faucet mounting hole 22 can be performed more easily.

After the presser plate 2 is inserted, the presser plate 2 automatically returns to the state shown in FIG. 2 by the elastic restoring action of the support pin 5, so that the position of the screw hole 4B is confirmed by the faucet mounting hole 2.
Even if the bolt 4 is not inserted into the faucet mounting hole 22 simply by passing the other bolt 4 through the support pin hole 4A, the bolt 4 is screwed into the screw hole 4B as it is, without looking through the upper part of the bolt 2.

At this time, as shown in FIG. 6, if the tapered portion 31 having a diameter larger than that of the bolt 4 is formed above the screw hole 4B, the position of the holding plate 2 is not completely restored, and the bolt 4 and the screw 4 Even if the axis of the hole 4B is slightly misaligned, the bolt 4
As long as the tip of the bolt abuts on the inner surface of the tapered portion 31, the bolt 4 is naturally guided to the screw hole 4B, and the bolt 4 can be easily and surely screwed into the screw hole 4B.

When the bolts 3 and 4 are tightened, the top plate 21 is sandwiched between the faucet fixing bracket 1 and the holding plate 2, and the faucet fixing bracket 1 is firmly attached to the top plate 21. Incidentally, the tapered portion 31 is formed such that the upper surface opening of the holding plate 2 has a larger diameter than the bolt 4 and gradually becomes smaller from the upper surface to the lower surface.

In the present embodiment, the faucet fixing bracket 1 is used.
And the holding plate 2 are connected by using two bolts 3 and 4, but the number of bolts may be one or three or more. However, if the number of bolts becomes three or more, the faucet mounting hole 22
Is relatively narrow, so the workability at the time of insertion is reduced, and if two bolts are used to tighten at both ends, even if other parts than both ends are further tightened, the improvement of the fastening force cannot be expected so much Therefore, there is a possibility that practicality is lacking.

In this embodiment, the faucet fixing bracket 1
Although a faucet is taken as an example of an article to be fixed to a water faucet, it goes without saying that the present invention can be applied not only to a faucet but also to a fixing device for fixing other articles.

[0030]

As described above, according to the fixing device of the present invention and the method of mounting the same, the following effects can be obtained. (A) Since the holding plate is retracted from the position facing the fixture and inserted into the mounting hole, it is possible to effectively avoid interference between the fixture and the mounting destination without increasing the bolt length. The holding plate can be easily inserted into the mounting hole, and the number of bolt tightening times can be reduced. In particular, when the bolt is eccentric from the center of the fixture and the holding plate, the holding plate can be largely retracted from the position facing the fixture, and the insertion work into the mounting hole can be performed more easily. . (B) After the holding plate is inserted into the mounting hole, the holding plate automatically returns to the position facing the fixture, so that the bolt can be easily tightened without confirming the position of the screw hole. In particular, when the screw hole has a tapered portion with a diameter larger than that of the bolt, the bolt is guided to the screw hole by the guide function of the tapered portion even if the return position of the holding plate is not complete, and the bolt is fastened. Can be performed easily and reliably. (C) When the fixing member and the holding plate are connected by two bolts, very strong tightening can be performed without impairing the workability of insertion into the mounting hole. Therefore, the fixing device, and thus the article fixed thereto, can be firmly fixed to the predetermined attachment destination for a long period of time.
