Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pipe cover for a faucet. Specifically, the present invention relates to a water supply pipe for a faucet with a wall and a pipe cover for covering the hot water supply pipe.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 9, a water faucet is laid on the back of a wall and a water supply pipe (including a hot water supply pipe) is taken out to the wall surface, and crank type leg pipes are respectively attached to the water supply pipe. The faucet body is connected via. This configuration will be described in detail below. First, the end portion of the water supply pipe laid behind the wall forms a leg pipe connection portion (for example, an elbow) that is buried so as to be substantially flush with the wall surface. A female screw is formed on the leg pipe connecting portion. Next, the male screw portion formed at the end portion of the crank type leg pipe is screwed into this female screw to connect the leg pipe to the water supply pipe. In addition, when screwing in, in order to maintain watertightness, a sealing tape is wound around the male screw portion in advance.

Next, only the connecting portion between the water supply pipe and the leg pipe is covered with a pipe cover. (The crank type leg pipe itself is not covered by the pipe cover and is exposed.) This pipe cover is cup-shaped and has an opening at the center. When connecting the leg pipe to the water supply pipe, the leg pipe cover is slid in advance to cover only the connecting portion. That is, the pipe cover is spirally rotated on the threaded portion of the leg pipe to cover only the connecting portion.

Further, a water faucet mounting portion (cap nut) is provided at the other end of the crank type leg pipe, and the leg pipes on the water supply side and the hot water supply side are set so as to have a predetermined space, The faucet is attached by connecting the faucet to the faucet mounting portion of the leg pipe. The cap nut is exposed without being covered by the pipe cover. By using the crank-type leg pipe in this way, it is possible to absorb the installation error of the leg pipe connection portion by the contractor on site.

[0005]

However, when the conventional crank-type leg pipe is used, the crank-type leg pipe is exposed on the back side of the faucet, which causes a problem of poor appearance, that is, designability. Further, since hot water flows into the hot water supply pipe and the hot water supply pipe itself becomes hot, the heat insulating cover is attached to the hot water supply pipe, but the appearance is further deteriorated by attaching the heat insulating cover. In addition, when using a crank-type leg pipe, the material cost is increased because the crank part is subjected to an aesthetic surface treatment in order to maintain its appearance in consideration of the exposed part of the crank part. There is also a problem that the above-mentioned dimension up to the water supply port becomes large. (About 100 mm from the wall to the faucet body)

If the distance between the leg pipe connecting portions buried in the wall surface can be set to a predetermined dimension without being influenced by the contractor, this conventional crank type leg pipe can be dispensed with. .

In view of the above problems, the inventor of the present invention, in consideration of the above-mentioned problems, started to develop a design and a piping cover that can be reliably and easily installed. Since the wall panel is used in the unit bathroom, if the leg pipe connection portion is attached to the wall panel in advance at the factory, the attachment dimension (error) can be managed at the factory. Therefore, the installation error of the builder on site as described above does not occur. In other words, the faucet can be easily installed without the crank-type leg pipe that absorbs a construction error. Further, it is not necessary to use the crank type leg pipes, and the member cost can be suppressed. Further, by adopting the I-type leg pipe, the leg pipe between the faucet and the wall can be provided by a compact pipe cover of a substantially cylindrical shape or a substantially conical shape in which the dimension in the direction perpendicular to the axis of the leg pipe is suppressed. It can be completely covered and the appearance can be improved.

However, compared to a pipe cover that covers only the threaded portion of the crank-type leg pipe, in the case of such a substantially cylindrical or substantially conical pipe cover, the leg is covered in order to cover the entire leg pipe. The dimension becomes large in the axial direction of the pipe. Therefore, rattling may occur when the pipe cover is attached. And
The inventors have further researched and developed a mounting structure for a pipe cover that can be securely mounted without rattling, and came to the present invention.

In view of the above-mentioned problems, the present invention improves the appearance between the faucet and the wall and allows the pipe cover to be easily attached to the wall surface without rattling the leg pipe. An object of the present invention is to provide a structure for mounting a pipe cover of a water faucet that can be firmly attached in close contact.

[0010]

[Means for Solving the Problems] To solve the above problems,
According to claim 1 of the present invention, a water faucet pipe is installed from the front side of the wall to the water pipe laid behind the wall by connecting the water faucet to cover the connection between the leg pipe and the water supply pipe. In the mounting structure, an elastic member is provided around the leg pipe, and an end portion of the leg pipe has a locking portion for locking the elastic member, and a guide portion provided on an inner wall of a pipe cover and the locking portion. It is a pipe cover mounting structure for a water faucet, characterized in that the elastic member is sandwiched between the parts.

As a result, the elastic body is pressed between the locking portion and the projection provided on the inner wall of the pipe cover, and the pipe cover can be pressed against the wall surface by the restoring force of the elastic body, so that the pipe cover and the wall surface are separated from each other. Since there is no gap between them, the appearance of the pipe cover can be improved, and after the pipe cover is attached to the leg pipes, the elastic force stored inside the pipe cover causes the pipe cover to rattle against the leg pipes. Can be brought into close contact with the wall surface easily.

According to a second aspect of the present invention, the pipe cover is vertically symmetrically divided. Thus, even after the faucet is attached, the pipe cover can be attached so as to surely cover the leg pipe. In particular, since the pipe cover itself does not spirally rotate, but the spring which is an elastic body is used, the position of the mating surface of the divided pipe cover can be freely determined.

According to a third aspect of the present invention, a locking piece is formed inside the piping cover, and the piping cover is freely locked to the leg piping by the locking piece. Due to this, the locking piece serves as a guide,
There is no vertical deviation.

According to a fourth aspect of the present invention, the leg pipe has an I-shape, a cap nut is formed at an end to which the water faucet is attached, and the pipe cover has a substantially cylindrical shape or a substantially conical shape. The opening is formed on the front and rear sides, and is divided along the side, and the opening of this piping cover also covers the cap nut for mounting the faucet provided on the leg piping. It is attached to. This allows
When the I-type leg pipe is used, it is possible to lower the cost of parts and to suppress the above-mentioned dimension from the wall to the water discharge port of the faucet, as compared with the conventional crank-type leg pipe. Further, by covering even the cap nut of the leg pipe with the pipe cover, it can be made invisible and the appearance can be further improved. The leg tubing between the faucet and the wall can be completely covered with a tubing cover.
