Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a water tap installed on a wall.

[0002]

2. Description of the Related Art Some hydrants installed on a wall are shown in FIG.
As in the conventional example 1, a base 81 constituting the lower portion of the faucet body 20 is directly fixed to the wall H (Japanese Patent Laid-Open No. 10-280500).

[0003]

However, this conventional example 1
Is applicable only to the wall surface H in a specific surface state, and has low versatility. That is, there are various types of wall surfaces H such as a flat surface, a curved surface, and a curved surface. In the hydrant of Conventional Example 1, the back surface of the base 81 is changed for each wall H to be installed. It is necessary to do it. Moreover, in the first conventional example, the base portion 81 is
, It is necessary to use the entire faucet body 20 properly depending on the shape of the wall surface H to be installed. For this reason, multi-product production of the faucet body 20 having a particularly complicated structure is required, which eventually leads to an increase in the production cost of this type of faucet.

[0004] Further, in the water faucet of the conventional example 1, the faucet main body 2
0, and a flow path that connects a hot water supply pipe 84, a water supply pipe 23, and a mixing pipe 88 connected to the back of the base 81, that is, a hot water chamber. The water chamber 85, the water chamber 86, and the mixing chamber 87 are configured as internal channels of the base 81. For this reason, the base portion 81 is heated, for example, when discharging high-temperature water. Further, since the entire back surface of the base 81 is brought into contact with and fixed to the wall surface H, the wall surface H may be thermally deformed depending on the constituent material of the wall surface H. Therefore, it is necessary to install the device on the wall H made of a material having sufficient heat resistance, and it is difficult to install the device universally on the wall H made of various materials.

On the other hand, some water faucets in which a water faucet main body is installed on a trapezoidal portion include one in which the trapezoidal portion is fixed to a wall surface or arranged in front of the wall surface. Specifically, there is one in which the faucet body 20 is installed on a pedestal portion 82 attached to a wall surface h, as in Conventional Example 2 of FIG. 5 (Japanese Patent Application Laid-Open No. 8-291546). Then, this conventional example 2
According to this, unlike the above-mentioned conventional example 1, it is not necessary to selectively use the faucet body 20 having a particularly complicated structure according to the surface shape of the wall surface H.

However, the pedestal 82 functions as an abutment for firmly supporting the entire faucet 20, and needs to have a sufficiently rigid structure such as a box shape. Therefore, it is difficult to produce inexpensively many types of pedestal portions 82 having different back shapes according to the surface shape of the wall surface H. It is difficult to easily adapt to the wall surface H provided with.

[0007] Under such circumstances, it is demanded that this type of faucet be able to obtain a firm mounting state and be easily adaptable to wall surfaces H of various shapes. In particular, since the pedestal 82 constitutes an important design part of the water faucet, it is also demanded that the appearance of the pedestal 82 can be easily changed according to the color, pattern, etc. of the wall surface H. I have.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a water supply system capable of obtaining a firm mounting state and easily adapting to a wall in various states. Is to provide a stopper.

[0009]

Means for Solving the Problems In order to solve the above problems, first, the means adopted by the invention of claim 1 is that a stay fixed to a wall surface and a faucet main body standing upright on the stay are provided. And a cover that covers the stay.

In the present invention, the faucet body is firmly fixed to the wall surface via the stay, and the stay is concealed by the cover to ensure the design of the faucet. Therefore, by properly using the stays according to the condition of the wall surface or using a cover that is appropriately adapted to the appearance of the wall surface, a solid mounting state can be obtained, and the water tap can be mounted on the wall surface in various states (shape, appearance). Can be well adapted to That is, according to the present invention, the water tap can be sufficiently adapted to the wall surface in various states by properly using at least one of the stay and the cover, both of which can have a simple structure.

Further, according to the present invention, since the faucet main body is fixed to the wall surface via the stay, the contact area between the faucet main body and the wall surface can be reduced, or the contact between the faucet main body and the wall surface can be reduced. It can be eliminated. Therefore, since the heat of the faucet main body can be hardly transmitted to the wall surface, the water faucet of the present invention can be universally installed on the wall surface made of various materials.

The wall surface of the present invention includes not only a wall surface of a faucet installation space in a washroom, a kitchen, a bathroom, etc., but also a wall surface of faucet-related articles arranged in the installation space. Examples of the faucet-related articles include, for example, a vanity table, a sink, and the like. The wall of the washbasin to be installed or the wall of the sink of the sink (for example,
The wall H) shown in FIG. 5 can be exemplified.

Next, the means adopted by the invention of claim 2 is:
The hydrant according to claim 1, further comprising a holding member that is held and fixed between the stay and the wall surface to hold the cover.

[0014] The invention of claim 1 includes a mode in which the cover is fixed to the stay or the faucet body. However, according to the mode of fixing to the stay, the stay needs to have a more rigid structure or the cover needs to have a detachable structure, which may complicate the structure of the stay. In addition, according to the aspect of fixing to the faucet body, it is necessary that the faucet body has a structure in which the cover can be attached and detached,
The structure of the faucet body may be complicated.

On the other hand, if the cover is fixed using the holding member as in the second aspect of the present invention, the structure of the stay and the faucet main body will not be complicated. Moreover, this holding member
Since the stay and the wall are sandwiched and fixed, the stay can be mounted on the wall by a series of operations for mounting the stay on the wall. Therefore, the work of installing the hydrant does not increase due to the addition of the holding member.

Next, means adopted by the invention of claim 3 is as follows:
The water faucet according to claim 1 or 2, wherein the faucet body is screwed and fixed to the stay from a lower surface side of the stay.

According to the first or second aspect of the present invention, for example, a cylindrical portion having a male screw engraved on the peripheral surface is hung down from the bottom surface of the faucet main body, and the cylindrical portion is inserted into a stay provided in a stay. At the same time, a fixing member such as a nut with a flange is screwed into the inserted cylindrical portion from below the stay, and the stay is sandwiched between the faucet body and the fixing member, thereby forming the faucet body. An aspect of fixing to a stay is also included. However, according to this aspect, a large space for arranging the cylindrical portion and the fixing member below the stay or a large work space for rotating a tool such as a spanner in a substantially horizontal plane can be secured. Is required. Therefore, since the installation space for the water tap is expanded below the stay, the water tap may not be properly installed in an installation site where a sufficient empty space cannot be secured below the stay.

On the other hand, in the third aspect of the invention, since the faucet main body is screwed and fixed from the lower surface side of the stay, it is necessary to secure a space below the stay for disposing the tubular portion and the fixing member. Absent. Moreover, below the stay,
It is sufficient to rotate the tool such as the drawbar and tighten the screw, so there is no need to secure a large work space. Therefore, the water tap according to the third aspect of the present invention can be suitably installed even on an installation site where a sufficient empty space cannot be secured below the stay. Further, according to the third aspect of the present invention, the screw is arranged at a place where it is hard to stand out, and it is difficult for the screw to appear as an external appearance of the water tap.

Next, means adopted by the invention of claim 4 is as follows:
`` A cover is provided with a slit which is opened on the rear surface side and which is provided with a slit for inserting a mounting portion between the faucet main body and the stay, and a concealing portion which conceals a portion of the slit located behind the faucet main body. A water tap according to any one of claims 1 to 3. "

According to the fourth aspect of the present invention, since the cover is provided with the slit for inserting the attachment portion between the faucet main body and the stay, the work of attaching the cover from the front of the wall surface becomes easy. Moreover, since the portion of the slit located behind the faucet body is concealed by the concealing portion, the appearance of the faucet does not deteriorate due to the addition of the slit to the cover.
In addition, the concealing portion is not only a mode that covers the slit from above, for example, but also a portion that is fitted in the slit so as not to expose the step portion of the slit to ensure a beautiful appearance when a step occurs due to the slit. And various embodiments. Further, the concealing portion may be attached to each component member of the water faucet (faucet main body, holding member, etc.), but may be configured using a member separate from each component member. Is also good.

Next, the means adopted by the invention of claim 5 is as follows:
`` It is connected to the faucet body via a hose inserted inside the cover, and is provided with a spout that is supported so that it can be pulled out integrally with the hose with respect to the support portion of the faucet body, and the cover has a drain hole. The hydrant according to any one of claims 1 to 4, wherein the hydrant is provided.

In general, when a water discharging device is supported on the supporting portion so as to be able to be pulled out integrally with the hose, hot water transmitted from the water discharging device to the hose may enter the supporting portion. If the hose is inserted through the inside of the cover, the hot water may enter the cover from the inside of the support portion and accumulate in the cover.

On the other hand, in the invention of claim 5, a drain hole is provided in the cover, and hot water transmitted from the water discharging tool to the hose is processed through the drain hole. Therefore, hot water does not accumulate in the cover. Note that the “water spouting device” of the present invention includes not only a shower head that spouts shower water, but also a water spouting head that performs only straight water spouting, or a water spouting device for oral cavity or eye wash.

Note that the water discharging device may not include such a switching mechanism.

The stay 50 is fixed to the wall surface H and has the faucet body 20 erected on the upper surface thereof.
A faucet side fixing portion 51 to which the zero flange portion 27 is fixed;
A wall-side fixing portion 52 fixed to the wall surface H via the holding member 60 and the sheet packing P, and reinforcing ribs 53 arranged on both side surfaces are provided. In addition, as described later, the stay 50 does not participate in fixing the cover 70. In other words, the stay 50 has a simple shape with a substantially L-shaped cross-section because no locking portion or the like for fixing the cover 70 is provided on the stay 50 at all.

The faucet side fixing portion 51 is provided with a notch portion 54 which is opened at the front end face thereof.
Is inserted through the opening 28 on the lower end side of the faucet main body 20 and each pipe (hot water supply pipe, water supply pipe 23, communication pipe 24, and hose 45) extending from the opening 28. Further, the planar shape of the cutout portion 54 is smaller than the planar shape of the flange portion 27 of the faucet body 20. Further, a notch portion 54 in the upper surface of the faucet side fixing portion 51 is provided.
A portion located on the periphery of the contact portion constitutes a contact surface with which a step-shaped contact surface 35 provided in the opening 28 on the lower end side of the faucet body 20 contacts (see FIG. 3).

Further, each of the faucet side fixing portion 51 and the wall surface side fixing portion 52 is provided with an insertion hole 56 through which the screw N is inserted. However, the embodiment of the stay of the present invention is not limited to this example. For example, the wall-side fixing portion 52 may be provided upward from the far end of the faucet-side fixing portion 51, or the wall-side fixing portion 52 may be provided both upward and downward from the far end. it can.

According to the second aspect of the present invention, the holding member 60
It is sandwiched between the stay 50 and the wall surface H and fixed to the wall surface H. However, in this example, the back surface of the holding member 60 and
The sheet packing P is interposed between the wall H. The holding member 60 has a substantially similar shape whose outer shape is slightly larger than that of the stay 50, and an upper plate portion 61 substantially similar in shape to the faucet side fixing portion 51 of the stay 50;
0 vertical wall portion 62 having a substantially similar shape to the wall side fixed portion 52
And The upper plate portion 61 is provided with a cutout portion 64 similar to the cutout portion 54 of the stay 50, and the vertical plate portion 62 is provided with a through hole 65 similar to the through hole 55 of the stay 50. I have.

The upper plate portion 61 is a portion which is sandwiched between the flange portion 27 of the faucet main body 20 and the faucet-side fixing portion 51 of the stay 50 when the faucet is installed (see FIG. 3). The edge has a stepped shape, and a guide portion 66 for facilitating mounting of the cover 70 is formed. The vertical plate 62
Is a portion sandwiched between the stay 50 and the wall surface H, and a locking portion 67 for locking the cover 70 protrudes from both left and right side surfaces and the lower surface. Further, also in the vertical plate portion 62, guide portions 68 for facilitating the mounting of the cover 70 are provided on both sides of each locking portion 67 in a substantially plate shape.

When the holding member 60 is employed, it is not limited to being sandwiched between the stay 50 and the wall surface H as in the second embodiment. The structure may be fixed. Also,
In each of the first, third to fifth aspects of the present invention, the use of the holding member 60 is omitted, and the cover 70 is attached to the stay 5.

The locked portion 76 of the bottom wall of the cover 70 communicates the inside and outside of the cover 70 and also functions as a drain hole 76 according to the invention of claim 5. However, in the invention of claim 5, the drainage hole 76 and the locked portion 76 may be provided separately.

In the present invention, since the faucet main body 20 is not supported by the cover 70, high strength is not required for the cover 70 itself. Therefore, as a constituent material of the cover 70, not only a metal having high strength in general but also a resin, pottery and the like, which are generally low in strength as compared with metal or the like, can be selected. In particular, when a resin is selected as a constituent material, a concave portion such as the locked portion 75 illustrated in this example, or a locking portion 76
This is preferable because it can be easily formed integrally with a hole portion such as the (water drainage hole 76).

In the above faucet, first, the stay 5
0 is fixed to the wall surface H using screws N with the holding member 60 and the sheet packing P interposed therebetween. At this time, the through-hole K of the wall H is exposed inside the room by the through-hole 55 of the stay 50, the through-hole 65 of the holding member 60, and the through-hole A of the sheet packing P. In the present example, a substantially planar wall surface H that stands substantially vertically is illustrated. However, unlike the present example, when the wall surface H stands in a curved shape, a bent shape, an inclined shape, or the like, The stay 50 and the holding member 60 are
What is necessary is just to make it the shape corresponding to this wall surface H.

Next, the faucet body 20 is placed above the stay 50.
The screw N is screwed into the female screw part 25 of the faucet body 20 from the lower surface side of the stay 50 according to the invention of claim 3, and the faucet body 20 is erected and fixed. At this time, the hot water supply pipe, the water supply pipe 23, the connecting pipe 24, and the hose 45 are in a state of being inserted into the through hole K. And in this example, the faucet main body 2
0 hot water pipe, water pipe 23 and liaison 2 connected inside
4 are connected to a hot water supply source, a water supply source, and a hose 45, respectively, behind the wall H. The method of processing each pipe is not limited to this example. The pipe processing such as the connection between the hot water supply source and the hot water supply pipe, the connection between the water supply source and the water supply pipe 23, and the connection between the communication pipe 24 and the hose 45 is performed on a wall surface. It may be performed on the front side of H.

Further, the cover 70 is pressed into and attached to the holding member 60 from the front thereof. In this operation, the guide portion 74 of the upper wall of the cover 70 and the guide portion 66 of the holding member 60 are slid against each other in a sliding manner, and the inner surfaces of both side walls and the bottom wall of the cover 70 are held together by the holding member 62 Guide part 6
8 by sliding contact with the holding member 6
The operation is completed by locking the 0 locking portion 67 to the locked portions 75 and 76 corresponding to the cover 70.

Of the slits 73 of the cover 70 thus mounted, a portion 7 located behind the faucet body 20
8 (see FIG. 2) is concealed by a concealing portion 29 extending from the flange portion 27 and is not exposed as an external appearance, so that sufficient design of the water tap can be ensured. In particular, in this example, since the slit 73 is covered and concealed from above by the concealing portion, the end face of the slit 73 is not exposed, and the beauty is further improved. However, the present invention is not limited to this example, and the slit 73 may be inserted into the side surface of the concealing portion 29 of the faucet main body 20 so that the concealing portion 29 does not expose the step on the end face of the slit 73. Further, the concealing portion 29 is attached to the faucet body 2
It may be attached to a member other than 0 or may be constituted by a separate member. For example, the concealing portion 29 that can be fitted into the portion 78 can be raised from the upper surface of the upper plate portion 61 of the holding member 60.

When the wall surface H is provided in various states, it is preferable to select and use various forms of the cover 70. For example, unlike the present example, when the wall surface H is erected in a curved shape, a bent shape, an inclined shape, or the like,
A cover 70 having a shape corresponding to the wall H may be used. In addition, according to the color, pattern, material, and the like of the wall surface H, a cover 70 having an appropriate appearance can be used.

In this embodiment, the faucet body 20 contacts the wall surface H only at the rear end surface of the concealing portion 29, and the contact surface between the faucet body 20 and the wall surface H is reduced. Moreover, since the hot water supply pipe and the connecting pipe 24 are connected in the middle of the faucet body 20 and are merely inserted in the lower half of the faucet body 20, the lower half of the faucet body 20 is heated. It has become difficult. For this reason, the water tap of this example can be suitably installed on the wall surface H made of a material having poor heat resistance.

According to the present invention, as described above, the stay 5
By properly using the cover 0 and the cover 70, it can be properly applied to the state of the wall H constituting the installation position of the water faucet. Can adapt. For example, when the sink of the sink or the washbasin of the vanity is installed at a location separated from the wall surface, it is preferable to use a stay or a cover that increases the amount of protrusion from the wall surface. Thereby, the water spouting position of the water faucet (for example, the position of the water spouting device) can be separated from the wall surface, and more accurate water spouting can be performed on the sink or the basin ball.

[0045]

As described above, according to the present invention, a water tap can be obtained which can be firmly mounted and which can easily be applied to wall surfaces in various states.
