DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover faucet provided with a cover that is not easily removed at a manufacturing site or a maintenance site, although it is easy to attach and detach.

[0002]

2. Description of the Related Art In a cover faucet, a cover which does not interfere with the faucet body when detaching / attaching is sometimes used. For example, in the case of a deck-type cover faucet in which a handle is arranged on a side portion, if a cover having open portions on the bottom surface and side surfaces is used, the cover does not interfere with the faucet body at the time of attachment and detachment. Can be smoothly attached and detached.

[0003] A cover of this type is generally fixed to the faucet body by a technique such as screwing. For example, a cover nut is used to attach a water discharge pipe or the like to a faucet body, and the faucet body is used to fasten and fix a cover together.

[0004]

However, this fixation is
It is generally performed at the final stage of the manufacture of the cover faucet (eg, before shipping). Therefore, when the cover faucet is on the production line, the cover is usually not fixed, so that the cover may be accidentally pulled out of the faucet body and fall to the floor or the like to be damaged. . Also, when replacing the water discharge pipe, the cover may be accidentally pulled out at the time when the cap nut or the like is removed.

[0005] Therefore, in order to avoid this withdrawal, workers on the production line, maintenance workers, and the like need to carry out their own work more carefully than necessary. Maintenance workability may be reduced.

The present invention solves the above-mentioned problems, and is provided with a cover water provided with a cover capable of reliably preventing inadvertent withdrawal at a manufacturing site, a maintenance site, etc., despite the fact that it is easy to attach and detach. It is intended to provide a stopper.

[0007]

The cover faucet of the first aspect is attached to and detached from a faucet body having a projecting portion along a direction different from the projecting direction of the projecting portion. And a cover having a main cover body provided with an opening for exposing the protruding portion to the outside after attachment, and inserting the protruding portion in a direction different from the attaching / detaching direction of the main cover body. A pull-out preventing member provided with an insertion portion to be inserted is attached to the opening portion.

In the present cover faucet, a detachment prevention member which is an interference object of the protruding portion is attached to the open portion, so that the main cover is reliably prevented from being detached. Incidentally, the “cover” of the present invention may be constituted only by the main cover body, or may be constituted as a connection body between the main cover body and another cover body.

Also, since the removal prevention member is usually attached after the main cover is attached and removed before the main cover is removed, it is difficult for the prevention member to hinder the smooth attachment / detachment of the main cover. Absent. Furthermore, according to the present invention, since the removal of the main cover body is prevented by the function of the removal prevention body, the fixing of the cover body using screws or the like can be omitted.

The "projecting portion" of the present invention is a portion which projects in a direction different from the attaching / detaching direction of the cover and is exposed from the cover when the cover is put on. For example, a water spout,
In addition to the parts that protrude from the faucet body, such as the shower elbow, faucet handle, faucet lever, etc., the protruding mounting provided on the faucet body for attaching these parts Examples thereof include a part (for example, a connecting part of a water discharge pipe and a part for attaching a faucet handle), and a mounting bracket (for example, a cap nut) used for mounting parts such as a water discharge pipe to this mounting part.

Further, the "prevention member" of the present invention is designed such that when the main cover body attached to the faucet body is to be withdrawn,
It interferes with the protrusion and hinders the removal.
The “insertion part” is not limited to a hole-shaped part (a part that becomes an interference object in the entire circumferential direction). And the like).

According to a second aspect of the present invention, in the cover faucet of the first aspect, a sub cover is attached to the faucet main body, and the main cover is attached to the sub cover. .

According to the present invention, the main cover body and the pull-out prevention body are firmly attached to the faucet body via the sub-cover body, so that the main cover body can be more reliably prevented from being pulled out. .

[0014]

Embodiments of the present invention will be described below. In the present embodiment, a specific example of the first and second aspects of the present invention will be described using a deck-type cover faucet.

As shown in FIGS. 1 and 2, the cover faucet includes a faucet main body 10, a lower cover body 20 as a sub-cover body constituting the cover, and a main cover body as a main cover body constituting the cover. An upper cover body 30 and a pair of left and right side caps 50, 50 each showing a specific example of a removal prevention body are provided.

As shown in FIG. 2, the faucet main body 10 has a built-in temperature control device 11 for adjusting the mixing of hot and cold water and a switching device 12 for adjusting the flow rate and switching the water discharge direction. . Also, as shown in FIG. 1, from the left end of the faucet main body 10, a mounting portion 13 composed of a spindle for operating the temperature control device 11 and a cylindrical portion through which the spindle can be moved forward and backward.
From the right end, a mounting portion 14 composed of a spindle for operating the switching device 12 and a cylindrical portion through which the spindle is removably inserted protrudes.

Further, as shown in FIG. 2, on both sides of the bottom surface of the faucet main body 10, a water side connection portion 15 for connecting a water supply pipe screw A and a water supply pipe screw B are connected. And a hot-water-side connecting portion 16 are provided in a substantially cylindrical shape. A callan side connection portion 17 for connecting the water discharge pipe T is provided substantially in the center of the upper surface in a substantially cylindrical shape. Further, as shown in FIG. 3, a shower-side connecting portion 18 for connecting the shower elbow E protrudes in a substantially cylindrical shape from substantially the center of the back surface.

As shown in FIG. 3, a recess 19 is provided substantially at the center of the front surface of the faucet main body 10, and a female screw portion M provided at the back end thereof has a substantially lid-shaped fixing cap K. Is screwed. The fixing cap K is provided with a female screw portion m along the axial direction.

The lower cover body 20 covers the lower front side of the faucet main body 10 and the lower side of both side faces, and has a substantially U-shaped outer shape as shown in FIG. A substantially U-shaped recess 21 is provided substantially at the center of the front surface.
1 is provided with a screw insertion hole 22 as shown in FIG. Then, the lower cover body 20 is fixed to the faucet main body 10 through the insertion hole 22 by inserting the small screw R into the female screw part m.
It is performed by screwing into.

Further, as shown in FIG.
The slide protrusions 25 used for connection with the upper cover body 30 are provided on both left and right sides of the front surface of the front cover 0 and the rear end surfaces of the both side plates 24.
Are formed.

As shown in FIGS. 4 and 5, the slide ridge 25 has both side surfaces 2a and 2a as inclined surfaces, and the width thereof gradually increases from the insertion start end 2c at the upper end to the insertion end 2d at the lower end. The tapered shape is widened. Further, from the insertion end portion 2d, toward the side of the other slide ridge 25 adjacent to the right or left, a substantially thin plate-like engagement portion 28 is formed.
Are projected in a substantially cantilever shape.

The upper cover body 30 covers the faucet body 10 to which the lower cover body 20 is attached, and has a substantially tunnel shape as shown in FIG. In addition, mounting portions 1 of the faucet main body 10 are provided on the open portions 31 and 32 on both side surfaces.
3 and 14, and the faucet body 1 is inserted into the opening 33 on the bottom surface.
0 is attached and detached while inserting the other parts.

At substantially the center of the upper surface, a storage portion 34 in which the above-described callan side connection portion 17 is stored is raised up in a substantially cylindrical shape. Further, as shown in FIG. 3, a notch S for inserting the shower elbow E is provided substantially in the center of the back surface.

On each side surface, as shown in FIG. 1, each upper half is formed as a substantially semi-elliptical cutout portion P, and each lower half is formed as a pair of thick portions W. . Each thick portion W has a slide groove 35 corresponding to the slide ridge 25 described above.
Is provided.

As shown in FIGS. 4 and 5, the slide groove 35 has a shape in which the slide ridge 25 is substantially inverted with respect to the unevenness. That is, the left and right side wall surfaces 3a, 3a are inclined surfaces, and the insertion opening 3d at the lower end from the insertion rear end 3c at the upper end.
It is a tapered groove whose groove width gradually increases toward. A substantially rectangular notch is provided in the insertion opening 3d toward the other slide groove 35 adjacent to the right or left side. The part 38 is provided.

The lower cover 20 of the upper cover 30
As shown in FIG. 5 (a), the connection is performed while the former slide grooves 35 and the latter slide protrusions 25 are slidably fitted. By such slide fitting, as shown in FIG.
a, 2a and both side wall surfaces 3a, 3a of the slide groove 35 are in surface contact, and the two cover bodies 20, 30 are positioned in the connection direction and the left-right direction.

In this embodiment, the insertion start end (upper end surface) 2c of the slide ridge 25 and the insertion rear end (rear end surface) 3c of the slide groove 35 are in contact with each other. A “gap” may exist.

When this slide fitting is performed, as shown in FIG. 6, the engaged portions 38 at the four corners on the bottom side of the upper cover body 30 are formed.
However, with respect to the corresponding engaging portion 28 of the lower cover body 20,
The upper cover 30 is engaged in the front-rear direction, that is, in the “anti-” expanding direction. Moreover, the upper cover body 30 is fixed to the lower cover body 20 in the left-right direction different from the front-rear direction by the above-described surface contact. For this reason, the engaged state of the engaged portion 38 and the engaging portion 28 becomes strong,
The opening of the upper cover body 30 is reliably prohibited.

That is, since the upper cover body 30 has a structure capable of expanding in the direction in which the open portions 31 to 33 on both side surfaces and the bottom surface are widened, if the cover body 30 alone is attached to the faucet body 10 alone. However, there is a risk of accidentally expanding and falling off.
In the present embodiment, this attachment is performed while being connected to the lower cover body 20, and the above-mentioned “surface contact” and “engagement” are used to prevent the spread.

In this embodiment, since the engaging portion 28 is provided on the slide ridge 25 and the engaged portion 38 is provided on the slide groove 35, the structure of each of the covers 20, 30 is not complicated. Furthermore, since the engaging portion 28 and the engaged portion 38 are concealed and do not appear as an appearance, the engaged portion 38 and the like do not impair the appearance of the cover faucet.

As shown in FIG. 1, the side cap 50 is fitted into the notch P of the upper cover body 30, and has a substantially semi-elliptical planar shape. The cap 50 has an insertion hole 51 through which the above-mentioned attachment portions 13 and 14 are inserted along the axial direction (a direction different from the attachment / detachment direction of the upper cover body 30). Further, the cap 50 has an elastic engagement piece 52 protruding from the back surface thereof. The cover body 30 is attached to the open portions 31 and 32 on both sides by engaging the engagement pieces 52 with the inner wall surfaces on both ends of the upper cover body 30.

Here, as shown in FIG. 7A, assuming that the cover faucet does not have the side cap 50, the upper cover body 30 is fixed until it is fixed to the faucet main body 10 with screws or the like. There is a possibility of accidental escape. On the other hand, FIG.
As shown in (b), when the side cap 50 is attached, the mounting portions 13 and 14 are caught by the side cap 50 even if the upper cover body 30 is to be pulled out. Moreover, since the upper cover body 30 is connected to the lower cover body 20 fixed to the faucet main body 10, and as described above, the upper cover body 30 is prohibited from being expanded, the upper cover body 30 is closed. Can be reliably prevented from coming off.

In this embodiment, as shown in FIG. 2, a faucet of the upper cover body 30 is fixed by a fixing metal (cap nut) 70 used for connecting the water discharge pipe T and the callan-side connecting portion 17. Final fixing to the main body 10 is performed. Specifically, the flange portion of the fixing bracket 70 and the callan-side connection portion 17
The upper cover body 30 is sandwiched and fixed between the upper cover and the upper surface.

In this embodiment, as shown in FIG.
A temperature control handle 81 for operating the temperature control device 11 is disposed on the left mounting portion 13, and a right mounting portion 14 is provided on the right mounting portion 14.
A switching handle 82 for operating the switching device 12 is arranged.

Next, other features of the present embodiment will be described.
In this cover faucet, the lower cover body 20 is firmly screwed and fixed to the faucet body 10 and the upper cover body 30 is fixed.
Is connected to the lower cover 20 and the upper cover 3
Since the removal of 0 is reliably prevented by the operation of the side cap 50 and the like, the entire cover is firmly attached to the faucet main body 10.

In the cover faucet, the lower cover 2
0 is fixed at one point except for both ends of the faucet main body 10, and as shown in FIG.
Even when the cover composed of the upper cover body 30 is not properly attached to the faucet main body 10, the correction can be easily performed, and the lower surface of the cover and the lower surface of the faucet main body 10 can be flush. .

If the cover is fixed to the faucet body 10 using a plurality of screws, even if it is found that the cover is tilted at the time of shipping or construction, it is very important to correct it. Requires effort. In order to perform this correction, after removing the water discharge pipe T, the shower elbow E, and the like from the faucet main body 10, remove a plurality of screws and screw each screw while paying careful attention so that the cover does not tilt. This is because it is necessary to attach the water discharge pipe T and the like.

On the other hand, in this embodiment, since the lower cover body 20 can be rotated about the small screw R as a rotation center, the inclination of the entire cover can be corrected instantaneously. At this time, it is not necessary to remove the water discharge pipe T, the shower elbow E, and the like (however, the fixing fitting 70 and the like are loosened as necessary). As described above, since the post-correction of the inclination of the cover is easy, the cover 2
Attachment of 0 and 30 can be easily performed, and workability such as production, construction, and maintenance of the cover faucet is improved.

Further, in the present cover faucet, it is not necessary to perform this correction work directly on the cover itself. That is, as shown in FIG. 8A, when the cover is tilted, the fixing nuts G and H screwed to the pipe screws A and B are tightened.
A part N of the lower surface of the cover contacts the deck surface J. In this state, when the fixing nuts G and H are further tightened, the cover rotates with the small screw R as a rotation center and a part N of the lower surface of the cover as a point of application of a rotational force, as shown in FIG. To
This is because the inclination is self-corrected.

Further, in the present cover faucet, the small screw R and the concave portion 21 are concealed by the upper cover body 30, so that the appearance is excellent.

The scope of each invention is not limited to the above-described embodiment, and various modifications can be made within the scope of each invention.

That is, the faucet main body 10 is attached to the mounting portions 13, 1
In the case where the upper cover body 30 has “another opening” through which the “other projection” is inserted instead of or with the mounting portions 13 and 14 instead of or 4 An "other side cap" may be arranged for the "other opening".

For example, the callan-side connecting portion 17 is connected to the faucet main body 1.
0, the upper cover 30 is provided with an opening through which the upper cover 30 is inserted.
Alternatively, a side cap having an insertion hole through which the hole can be inserted may be used.

Further, unlike the present embodiment, the engaging portion 28 and the engaged portion 38 can be exposed as a cover faucet. For example, the insertion end 2 of each slide ridge 25
d and a lower surface of the lower cover body 20, an L-shaped engaging portion 28 is projected from the lower surface of the lower cover body 20, and the engaging portion 28 is
(These surfaces constitute the engaged portion 38).

Further, the slide ridge 25 and the slide groove 3
5 is not limited to the substantially tapered shape of this embodiment. For example, as shown in FIG. 9, a modified example using a straight type (constant cross-sectional area type) slide protrusion 25 and a straight type (groove width, groove depth constant type) slide groove 35. Can be exemplified.

However, this embodiment is superior to this modification in the following points. In a modified example, both cover bodies 20, 30
It is necessary to accurately align the slide ridge 25 and the slide groove 35 in a corresponding relationship with each other with a slight clearance between them as an allowable error.

On the other hand, in this embodiment, this alignment is
As shown in FIG. 5A, the insertion start end 2c having a small size of the slide ridge 25 may be inserted into the insertion opening 3d having a large size of the slide groove 35.
That is, since it is sufficient to perform the positioning roughly, the connection work between the two cover bodies 20 and 30 can be performed more smoothly.

In a modification, both cover members 20 and 30
As shown in FIG. 9B, the positioning along the connection direction of (1) and (2) of the leading end surface (insertion start end) of the slide ridge 25 is performed.
It is necessary to bring the slide groove 35 into contact with the rear end face (insertion rear end portion) 3c. Therefore, in order to obtain sufficient positioning accuracy, the slide ridge 25 and the slide groove 3 are required.
It is necessary to improve the dimensional accuracy of No. 5.

On the other hand, in this embodiment, the positioning is performed by the side surfaces 2a, 2a of the slide protrusion 25 as described above.
Since the contact is performed by surface contact with both side wall surfaces 3a, 3a of the slide groove 35, sufficient positioning accuracy can be obtained even if the dimensional accuracy of the slide protrusion 25 and the slide groove 35 is roughened to some extent.

Further, in the modified example, the two cover bodies 20 and 30
After connection, as shown in FIG.
a, 2a and the side wall surfaces 3a, 3a, etc., there is a “gap 2g” due to the clearance between the slide ridge 25 and the slide groove 35.
There is a risk of relative "chatter" between 0 and 30. On the other hand, in this embodiment, since the slide ridge 25 and the slide groove 35 are in surface contact with each other, this “rattle”
Is unlikely to occur.

Considering that the cover members 20 and 30 of the modified example are integrally formed by using a resin or the like, as in this modified example, a molded article having a straight type slide ridge 25 and a slide groove 35 (FIG. It is difficult to remove the cover bodies 20, 30) from the molding die. Therefore,
It is necessary to complicate the structure of the molding die, and the manufacturing costs of the cover members 20 and 30 are likely to be high.

On the other hand, in the present embodiment, the slide ridge 25 and the slide groove 35 have a substantially tapered shape and have a shape having a “draft angle”. It is easy to remove the cover bodies 20 and 30 as molded products from the mold.

In this embodiment, both side surfaces 2a, 2a
A purely tapered slide ridge 25 with an inclined side and a purely tapered slide groove 35 with an inclined side wall 3a, 3a are illustrated, but these are one side 2a (one side wall 3a). It may be a substantially tapered one in which only the slope is inclined (for example, a key-shaped slide ridge 25 having a slope).

In the present embodiment, the slide ridge 2
5 (slide groove 35) was changed to have a “substantially tapered shape” by changing the width (groove width), but the thickness (depth) was changed, and the width (groove width) and thickness (depth) were changed. May be changed to have a “substantially tapered shape”.

Further, the slide ridge 25 and the slide groove 3
5 may be slid into a dovetail shape, and the dovetail portion may be used as the engaging portion 28 and the engaged portion 38. In this case, the main cover body 20 is firmly fixed not only in the lateral direction but also in the front-rear direction, and the engagement state of the engaging portion 28 and the engaged portion 38 is further enhanced. Further, the engaging portion 28 and the engaged portion 38 are connected to the slide ridge 25 and the slide groove 3.
5, there is no need to provide the cover members 20, 3 separately.
The structure of No. 0 can be simplified, and the engaging portion 28 and the engaged portion 38 can be prevented from appearing as the appearance of the cover faucet.

Further, the upper cover (main cover) 30
And the lower cover body (sub-cover body) 20 can be connected by a method other than slide fitting such as screwing.
