There is one disclosed in Japanese Patent Publication No. 063.

[0003]

In all of the above-mentioned conventional techniques, a faucet joint box is mounted inside a wall. Using this faucet joint box increases the cost, and the mounting is troublesome. In particular, Japanese Patent Publication No. 4-65935 has a problem that it requires skill to fix the faucet joint box because the lock nut of the faucet joint box is once opened when the faucet is renewed.

[0004]

In order to solve the above problems, the present invention has a fixing ring for fixing a water supply pipe or a water supply pipe for hot water supply inserted at one end of the elbow, and at the other end of the elbow. A faucet joint elbow having an outer screw formed on the outer periphery, a substantially rectangular seat plate at the base of the outer screw, and a tap hole for connecting the faucet inside, and the faucet joint elbow. A waterproof ring having a hole at the center of the disc for fitting with the outer screw part of the disk, a lock nut screwed with the outer screw of the faucet joint elbow, and a strip plate bent into an L-shape, The faucet joint elbow was made to pass through the vertical plate and the wall plate while being able to be fixed to the back surface of the wall plate, and the horizontal plate part was covered with the water pipe connected to the faucet joint elbow. So that the sheath tube can be fixed By the the L-shaped fitting constitutes a faucet joint.

Further, the strip plate is bent into an L shape so that the vertical plate portion thereof can be screwed to the back surface of the wall plate, and the central portion thereof has an opening through which the fixing ring side of the faucet joint elbow can be inserted. A screw hole for screwing the seat plate of the faucet joint elbow is provided on both side edges of this opening, and a horizontal plate has a bellows-like sheath pipe covered with a water pipe connected to a fixing ring of the faucet joint elbow. An L-shaped metal fitting is constructed by providing a hole for fitting with.

Further, a water pipe of a predetermined length is connected to the fixing ring of the water faucet joint elbow of the water faucet joint of the first aspect of the invention, and a sheath pipe of a predetermined length is covered on the water pipe, and the water faucet joint elbow is connected. May be fixed to the L-shaped fitting through the seat plate, and the end portion of the sheath tube on the faucet joint elbow may be fitted to the horizontal plate portion of the L-shaped fitting in advance to be assembled.

In addition, the width of the opening provided in the wall plate for mounting the faucet joint elbow and the width of the substantially rectangular seat plate of the faucet joint elbow are set so that there is no gap when they are fitted together. Should be approximated to.

Further, using the water faucet joint of the first invention described above, the outer threaded portion of the water faucet joint elbow is penetrated into a hole provided in the wall plate adjusted to a predetermined thickness by a wall plate adjusting member. , Fixing the L-shaped metal fitting to a wall plate, and screwing the lock nut to the protruding screw portion through the waterproof ring to fix the water faucet joint elbow so that the water faucet joint can be attached to the wall .

[0009]

As described above, according to the present invention, the faucet joint elbow is fixed to the L-shaped fitting without using the faucet joint box, and the L-shaped fitting is attached to the back wall of the bathroom, toilet, washroom or the like. Since the plate can be accurately fixed at a predetermined position, the construction is easy and the water faucet can be fixed securely, and the cost is reduced because the water faucet joint box is not used. Further, even when the water pipe is renewed, the water pipe can be renewed by removing the fixing ring of the water faucet joint elbow and the water pipe, so that the renewal can be performed quickly and easily.

Further, the L-shaped metal fitting of the second invention has a simple structure and is easy to manufacture as compared with the conventional faucet joint box, and when this L-shaped metal fitting is used, the faucet can be attached and Repair work is also easier than in the past.

Further, as in the third invention, if the L-shaped fitting, the water faucet joint elbow, the water pipe and the sheath pipe of a predetermined length are assembled in advance as a unit in a factory,
Installation of faucets on-site becomes quick and easy. Further, in this case, since the water pipe can be surely covered with the sheath pipe, the sealing cap and the like which are conventionally provided on the exposed portion of the water pipe are not necessary.

Further, as in the fourth aspect of the invention, the width of the opening provided in the wall plate for mounting the faucet joint elbow and the width of the substantially rectangular plate-shaped seat plate of the faucet joint elbow are fitted to each other. If the distance is approximated to the extent that there is no gap at the time, the center of the opening of the wall and the center of the outer threaded portion of the water faucet joint elbow will not be significantly displaced, and the construction accuracy will be improved.

As in the fifth aspect of the invention, the water faucet joint of the first aspect of the invention is used, and the external thread portion of the water faucet joint elbow is provided on the wall plate adjusted to a predetermined thickness by the wall plate adjusting member. The water tap joint elbow is fixed by penetrating the hole and fixing the L-shaped metal fitting to the wall plate, and screwing the lock nut through the waterproof ring to the protruding screw portion of the water faucet joint elbow. The thickness of the wall plate to which the joint elbow is attached is always made substantially uniform by the wall plate adjusting member, and the size of the faucet joint elbow is sufficient, which is very advantageous in construction.
