Description

  The present invention relates to a water faucet with a cover, and more particularly, to a water faucet with a cover in a form in which respective operation portions of a rotary left handle and a right handle protrude in the opposite directions from the left end and the right end of a faucet body.

Conventionally, there has been known a faucet in which operation portions of a rotary left handle and a right handle are protruded in opposite directions from the left end and the right end of the faucet body.
As a typical example, a mixed faucet of a type in which a faucet body is fixed to a wall by a pair of leg pipes that also serve as water and hot water pipes has been widely used.
As a leg tube in this case, a crank-shaped one (crank leg) having a first tubular body protruding in a horizontal direction from a wall and a second tubular body standing along the wall from its tip is generally used. .

The mixing faucet with the above leg pipe (hereinafter sometimes referred to as a faucet) is made of a metal casting by a pair of water side and hot water side leg pipes attached to the wall in a connected state to the original pipe behind the wall. It is possible to support a faucet body in which a valve part and other faucet mechanism parts are built in the body body.
In the case of using a crank leg as a leg tube, the pair of left and right crank legs on the water side and the hot water side are rotated in a direction parallel to the wall surface to adjust the rotation angle, and the amount of screwing into the main pipe is adjusted. By adjusting the position, the posture of the faucet body can be adjusted to a horizontal position, the distance between the faucet body and the wall can be made equal to the left and right (left and right in the front view as seen from the user), or It is possible to absorb a shift in the distance between the connecting portions with the crank leg and the connecting portion between the wall-side water and hot water source pipes.

By the way, in the faucet in which each of the left handle and the right handle protrudes from the faucet body in the left and right direction, as shown in FIG. 18, between the faucet body 300 and the operation portion 302A of the left handle 302, In addition, a gap S that penetrates deeply inward in the radial direction occurs between the faucet body 300 and the operation portion 304A of the right handle 304 in the left-right direction (the axial direction that is the rotational axis direction of the handle).
This gap S becomes a factor that reduces the appearance and aesthetics of the faucet.
The point that such a gap is formed between the handle and the operation part is also shown in the following Patent Document 1 in the figure.

  Conventionally, a faucet with a cover formed by covering the faucet body with a cover is known, and also in this faucet with a cover, there is a gap between the cover and the operation part of the left handle, and between the cover and the operation part of the right handle. There is a problem that occurs, and this gap reduces the appearance and aesthetics of the faucet with cover.

Since this water faucet with a cover has the following advantages, various types have been proposed.
In detail, in the case of a conventional faucet, the metal casting body body has the appearance of the faucet as it is. The outer surface is beautifully finished by plating.

  However, in this case, in order to achieve a good appearance, extra body is attached to the body body, the outer surface is flattened, the plating process is performed after the polishing process is performed, and thus the body body is inevitably heavy. Construction work is difficult, and the amount of casting material used is increased, and polishing and plating processes are required, resulting in high costs.

  In addition, in order to prevent burns when the user touches the main body, a water jacket structure is provided on the main body, and water is circulated there. Complicated and heavy.

In a faucet with a cover that covers the faucet body with a cover, in order to make the cover look like a faucet, extra body is attached to the body of the faucet and its outer surface is formed into a flat shape without unevenness. The weight can be reduced.
In addition, the cover can prevent the user from directly touching the main body, and the water jacket structure conventionally provided on the main body can be omitted.
Furthermore, in the faucet with a cover, it is possible to give the faucet various appearances by changing the type of the cover.

An example of such a faucet with a cover is disclosed in Patent Document 2 below, for example.
Even in such a faucet with a cover, a gap is generated between the cover and each operation portion of the left and right handles.
However, the conventional faucet with a cover only covers the faucet body mainly with a cover, and this point may be applied to a leg pipe, for example, a faucet with a crank leg attached to the wall by a crank leg. It is the same.

  In this way, in the case of a faucet with a cover that mainly covers only the faucet body, the cover is attached to the faucet body in advance at the factory production stage, and the faucet body with the cover is attached to the crank leg at the construction site. In addition to being easy to install and install on the wall, the cover can be pre-installed at the factory production stage, so the gap between the cover and the handle operating section is small, and the cover and left handle It is easy to control the gap between the operation unit and the gap between the cover and the right handle operation unit evenly.

  However, in a faucet with a crank leg, in the case of a faucet with a cover that only covers the faucet body mainly with a cover, the crank leg is exposed to the outside with the faucet installed and forms part of the faucet's appearance. As with a conventional faucet without a cover, it is necessary to apply a plating process to the crank leg to finish the appearance beautifully, and the process is expensive.

  In addition, if the crank leg is exposed to the outside with the faucet installed, the crank leg has a complicated bend shape, which complicates the appearance of the faucet and makes the crank leg dirty. In addition, the crank leg has a complicated bent shape as described above, so it is difficult to clean, and it tends to remain dirty, which deteriorates the appearance of the faucet.

Therefore, it is conceivable to configure the faucet with a cover in such a form that the faucet body and the crank leg are covered with the cover.
In this way, the cover can cover the crank leg from the outside together with the faucet body to hide the crank leg from the inside so that the crank leg does not appear on the outside. The crank leg can be easily cleaned, and it is difficult to clean the dirt. The aesthetics of the water faucet can be enhanced more than before.
Also, since the hot water side crank leg can be covered inside the cover, the user may unintentionally touch the hot water side crank leg and feel hot, or in some cases may cause burns. It can be lost.

However, on the other hand, if the faucet body is covered with the cover with the crank leg in this way, it is difficult to attach the cover to the faucet body prior to construction, and the crank leg and faucet body are attached at the construction site. After that, the cover must be attached to the faucet body for the first time.
In this case, since the cover is attached at the construction site, the cover must be easily attached, and the position accuracy of the cover attachment position is inevitably lowered.
In that case, the gap between the left end of the cover and the operating portion of the left handle, and the gap between the right end of the cover and the operating portion of the right handle tend to be uneven.
The non-uniformity of the gap is conspicuous, and becomes a factor that greatly reduces the aesthetics of the faucet and the quality of the faucet installation state.
Accordingly, in order to realize a faucet with a cover that covers the faucet body together with the cover of the crank leg, it is essential to solve these problems.

Japanese Patent No. 2686897 JP 2011-219959 A

Effects and effects of the invention

  As described above, according to the present invention, in the faucet with a cover in which the operation portions of the left handle and the right handle protrude in the opposite directions from the cover, the operation portions of the operation portions of the left handle and the right handle on the faucet body side are provided. Equipped with a cylindrical cover at the end, or separate from the operation part, and at the same radial position as the axial end of the operation part on the faucet body side, the faucet body follows the axial end. A cylindrical covering portion extending to the side is provided, and a cover is covered from the outside in the direction perpendicular to the axis with respect to the covering portion.

According to the water faucet with a cover of the present invention, a gap in the left-right direction that enters deeply inward in the radial direction is generated between the left end of the cover and the operation portion of the left handle, or the right end of the cover and the operation portion of the right handle. Can be prevented.
As a result, the appearance and appearance of the water faucet with a cover can be improved, and the quality of the faucet can be improved.

Even if there is a slight error in the mounting position of the cover in the left-right direction, the size of the protrusion of the cover from the cover (the protruding length in the left-right direction from the cover) The difference is not so conspicuous in the front view from the user, and the appearance and aesthetics of the faucet are not substantially impaired by the error in the mounting position of the cover in the left-right direction. Good appearance and appearance can be maintained.
