Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet box, a faucet elbow with ears, and a front plate for a faucet box, which is mainly used for an indoor opening of a water supply pipe.

[0002]

2. Description of the Related Art In buildings, water supply, hot water supply, heating and cooling pipes in buildings, hot water pipes, floor heating pipes, gas pipes, etc. in detached houses and facilities, it is flexible to the point where fluids such as water and gas are used. After running around the pipe, the faucet elbow is attached to the pipe, and the faucet, faucet, and cock are attached to the faucet elbow. At this time, in order to fix the faucet elbow, the faucet box is attached to, for example, a column, the faucet elbow is attached to the faucet box, and the inner wall is sandwiched between the faucet box and the front plate. Among these, there are various methods for attaching the faucet box, for example, there is one disclosed in Japanese Examined Patent Publication No. 3-50048 for attaching the back side to the erection bar, which is left and right on the back side of the faucet box. This is a fixing method in which a square hole extending in the direction is formed and the erection bar is inserted and fixed in the square hole, or a square groove having an open rear side is formed and the erection bar is inserted and fixed in the square groove. In addition, as for horizontal mounting on the pillar, conventionally, a screwdriver was inserted from the front side of the hole of the faucet box and screwed to the pillar.

Further, the pipe is usually covered with a corrugated pod, and therefore the pod is also fixed to the faucet box. However, the conventional method for fixing the pod is SAIKAI Sho 59-9.
There is one disclosed in Japanese Patent No. 0219. This relates to a connecting device for a corrugated conduit, and is a connecting device in which a plurality of through holes extending in the axial direction are provided in a receiving port, and a bowl portion similarly extending in the axial direction is provided in a connecting body. Further, as a technique for fixing the faucet elbow to the faucet box, JP-A-3-918 is known.
There is one disclosed in Japanese Patent Publication No. 7, which has a fixing structure in which a collar portion of a faucet elbow is sandwiched between an abutting portion of a faucet box and a fixing ring screwed to the faucet box. Further, as a technique for fixing the front plate, there are those disclosed in Japanese Patent Publication No. 3-50048 and Japanese Patent Laid-Open No. 63-265027. In this technique, the faucet elbow front side flange is clamped and fixed by the faucet box and the disk-shaped front plate screwed to the faucet box, but at the same time, the inner wall is fixed by the faucet box and the front plate. Is also sandwiched.

[0004]

Among the above-mentioned conventional techniques, the back mounting to the erection bar disclosed in Japanese Patent Publication No. 3-50048 has a vertical axis and a front-back direction when a square hole is formed. Is vulnerable to the moment load about the axis of No. 1, and when the square groove is formed, there is a problem that the moment load about the axis in the vertical direction can hardly be supported.
Further, in the above-mentioned conventional horizontal mounting method, since the front side of the hole of the faucet box is screwed, there is a problem that the flushness between the outer surface of the front plate of the faucet box and the inner surface of the inner wall collapses during screwing. . Furthermore, the conventional method of fixing the faucet box is manufactured only assuming that it is fixed in a specific direction, and it was not possible to fix it in various directions. There is a problem of lacking the flexibility of. In addition, the above-mentioned actual exploitation 59-9
The sheath tube fixing method disclosed in Japanese Patent No. 0219 causes a problem in horizontal mounting. That is, if horizontal mounting is attempted by screwing from the front side of the hole of the faucet box, the above problem occurs, so it is necessary to provide a side plate for horizontal mounting on the faucet box. If it is inserted from one side, interference occurs between the side plate and the connecting body, and the connecting body cannot be inserted. On the other hand, if the connecting body is inserted from the front side, the inner wall cannot be attached because the body of the connecting body projects beyond the sheath tube to the front side.

Further, in the fixing structure of the faucet elbow disclosed in the above-mentioned JP-A-3-9187, the collar portion of the faucet elbow is simply sandwiched between the faucet box and the fixing ring. Therefore, there is a backlash around the axis in the front-rear direction, and a special tool for screwing the fixing ring to the faucet box is required. In addition, the above-mentioned special fair 3
In the front plate disclosed in JP-A-50048 and JP-A-63-265027, since the front side flange of the faucet elbow and the inner wall are sandwiched at the same time, even if the inner wall thickness is slightly different. The inner wall cannot be clamped and fixed,
However, there is a problem in that it is not possible to deal with it when the thickness of the inner wall is different. Further, since the front plate is screwed to the faucet box, if an O-ring is interposed between the front plate and the inner wall to obtain a sealing property, the O-ring will be twisted. Further, since the front plate is exposed to the eyes, it cannot be formed in the shape of a hexagonal nut from an aesthetic point of view. Therefore, there is a problem that the tightening is weak and the tightening is weak.

Therefore, the present invention can be attached in various directions, and its strength is sufficient even when it is attached to the back side, and even when it is attached to the back side, the outer surface of the front plate of the faucet box and the inner surface of the inner wall are flush with each other. Does not collapse during screwing,
Moreover, it is an object of the present invention to provide a faucet box capable of reliably mounting the faucet elbow. It is another object of the present invention to provide a faucet elbow that is easy to mount on a faucet box and does not require a special tool.
A further object of the present invention is to provide a front plate for a faucet box that can perfectly accommodate inner walls of various plate thicknesses and that does not impair aesthetics.

[0007]

And upper side plates 4 and 4 provided on both sides of the upper plate 4 and the inclined plate 2, the rear plate 3, and the upper side plates 4 and 4 form a hole 5 into which the faucet elbow 20 is to be mounted, as shown in FIG. is doing. A step surface 5a is provided on the front side of the hole 5 with the front side open, and a recess 5b into which both ears of the faucet elbow 20 are fitted is formed in the step surface 5a.
5b is provided. At the lower ends of the rear plate 3 and the upper side plates 4 and 4, a tubular portion 6 for accommodating a pipe 21 connected to the faucet elbow 20 and a corrugated sheath pipe 22 covering the pipe 21.
Is provided, and a slit 6a extending in the circumferential direction is provided on the front surface side of the tubular portion 6. A front plate 7 is provided at the upper end of the inclined plate 2 and the front ends of the upper side plates 4 and 4, and a hole is formed in the center of the front plate 7, and a cylindrical inner wall insertion portion 8 is formed in the hole. The front plate 7 is provided with holes 7a for front mounting at four corners. Upper plates 9 and 9 are attached to the upper surfaces of the upper side plates 4 and 4 and the front plate 7, respectively, and notches 9a, 9a for attaching to the front and rear of the upper plates 9 and 9;
9a is provided.

At the lower ends of the upper side plates 4 and 4, enlarged portions 10 and 1 are provided.
The lower side plates 11 and 11 are provided through 0, and the notches 4a, 4a and 1 for horizontal mounting are provided at the same height of the upper ends of the upper side plates 4 and 4 and the lower portions of the lower side plates 11 and 11, respectively.
1a and 11a are provided. These cutouts 4
The a and 11a are formed at positions and sizes into which the shaft of the driver can be inserted. Therefore, as shown in FIG. 7, the cutouts 11a and 11a formed in the lower side plates 11 and 11 are located below the lower end of the tubular portion 6. It is located below. Further, at the same height above and below the upper side plates 4 and 4, recessed grooves 4b, 4b; 4b, 4b for attaching a rear surface from the rear surface side to the front surface side are provided. A projecting portion 12 is projected from the vicinity of the connecting portion between the inclined plate 2 and the front plate 7 toward the back side at the center of the concave grooves 4b and 4b in the vertical direction. A screw hole 12a is provided from the rear side toward the front side. Of the above, the rear plate 3, the upper side plates 4, 4, the front plate 7, the upper plates 9, 9, and the lower side plates 11, 11
Is formed so that the circumscribed shape is a rectangular parallelepiped. The faucet box 1 described above can be integrally formed by injection molding of a synthetic resin material such as polyethylene or ABS.

The water faucet box 1 of this embodiment is constructed as described above, and a method of using the water faucet box 1 will be described below. First, the faucet box 1 is fixed to a pillar, a beam, or the like. There are six possible directions for fixing the faucet box 1, that is, up, down, left, and right. However, since the pipe 21 is usually connected to the lower side of the faucet elbow 20 fixed in the faucet box 1, it is usually impossible to attach the faucet elbow 1 to the upper side of the beam. Further, since the inner wall of the building is usually fixed after fixing the faucet box 1, front mounting is not usually performed, but if front mounting is required, front mounting holes 7a provided at the four corners of the front plate 7 should be provided. You can use it.

Next, as shown in FIG. 3, the attachment for fixing the faucet box 1 to the lower side of the beam 31 is performed by screwing a screw 36 through an attachment notch 9a provided in the upper plate 9. Can be done. At this time, since the enlarged portion 10 of the faucet box and the lower side plate 11 are projected laterally, the notch 9a for attachment is inclined downward so as to project laterally as shown in FIG. Once formed, the driver will be easier to use. At this time, the screw 36 is obliquely screwed, but since it is screwed in parallel to the front plate 7,
The coplanarity between the outer surface of the front plate 7 and the inner surface of the inner wall 32 does not collapse during the screwing of the screw.

Next, an erection bar 3 laid between the pillars.
As shown in FIGS. 5 and 6, when attaching the back side to fix the back side of the water faucet box 1 to 3, the two mounting bars 33, 33 are fitted in the recesses 4b for attaching the back side of the upper side plate 4, and A washer 3 whose length in the direction is wider than the space between the upper side plates 4 and 4 and whose width in the vertical direction is approximately equal to the space between the upper and lower concave grooves 4b and 4b.
5 and the screw 36 is screwed into the screw hole 12a of the projecting portion 12 to carry out. Since the erection bar 33 is fitted into the four recessed grooves 4b vertically and horizontally separated and then tightened by the screws 36, the faucet box 1 has a vertical axis, a horizontal axis, and a longitudinal axis. Sufficient strength against moment load around the throat axis.

Next, horizontal mounting for fixing the faucet box 1 to the column 30 can be performed by using the horizontal notches 4a and 11a of the upper side plate 4 and the lower side plate 11, as shown in FIGS. . That is, when mounting on the left side, the washer 35 is applied to the notches 4a and 11a of the upper side plate 4 and the lower side plate 11 on the left side, and the shaft portion of the driver 37 is inserted from the notches 4a and 11a of the right side upper side plate 4 and the lower side plate 11. Then, the screw 36 is screwed into the column 30, and when the screw is right-mounted, the screw is screwed in the opposite way. Therefore, since the screw 36 can be screwed into the pillar 30 at a right angle, the flushness between the outer surface of the front plate 7 and the inner surface of the inner wall 32 does not collapse during screwing. The horizontal cutouts 4a and 11a of the upper side plate 4 and the lower side plate 11 can also be formed by horizontal side holes 4c and 11b as shown in FIG. As described above, this faucet box 1 can be attached in all five directions except underlaying, can sufficiently withstand an external force, and has the same planarity between the outer surface of the front plate 7 and the inner surface of the inner wall 32. There is no breaking down.

After fixing the faucet box 1 to a pillar or the like, the sheath tube 22 is attached to the faucet box 1. As shown in FIG. 4, the lock pin 15 used for this attachment includes leg portions 15b and 15b that sandwich the outer surface valley portion of the sheath tube 22 and a body portion 15.
a is projected from both sides of a.
The inside of the tip of b is curved inward. Both legs 15
An overhanging portion 15 protruding outward at the base of b, 15b
c, 15c are provided, and the protruding portion 15c,
15c is configured to contact the end surface of the slit 6a of the tubular portion 6 of the water faucet box. This lock pin 15
In order to connect the sheath tube 22 to the tubular portion 6 of the faucet box using, the packing 16 is externally fitted to the sheath tube 22 and inserted into the tubular portion 6 as shown in FIGS. Insert the lock pin 15 from 6a. As a result, the leg portion 15b of the lock pin is fitted into the outer surface valley portion of the sheath tube 22 and
Since the protruding portion 15c abuts the slit 6a to prevent the lock pin 15 from moving inward, a part of the lock pin 15 engages with the slit 6a to prevent movement in the axial direction. The sheath tube 22 is thus connected to the faucet box 1. At this time, the slit 6a is provided only at one place, and the trunk portion 15a of the lock pin is hidden in the slit 6a. Therefore, as is apparent from FIG. 4, the inner wall 32 can be attached without any trouble after connecting the sheath tube 22 from the front side by the lock pin 15.

After the connection of the sheath tube 22 is completed, the through hole 32a of the inner wall 32 is inserted into the inner wall insertion portion 8 of the faucet box to fix the inner wall 32 to a pillar, a beam or the like. At this time, as described above, the front surface 7 of the faucet box and the inner surface of the inner wall 32 are kept flush with each other even while the faucet box 1 is being attached, and the lock pin 15 interferes with the inner wall 32. Nor. After attaching the inner wall 32, the pipe 21 is inserted into the sheath tube 22 and the end thereof is pulled out from the inner wall insertion portion 8 of the faucet box, the faucet elbow 20 is connected to the pipe 21, and then the faucet elbow is connected. 20 is fixed to the faucet box 1. This faucet elbow 20 is a faucet elbow with ears having ears 20a, 20a on both sides as shown in FIGS. 10 and 11, and the ear 20a extends along the ears 20a on the back side of the screw holes of the ears 20a. The groove 20b is formed, and the faucet mounting portion is provided with screws on both the inner and outer surfaces thereof.
However, instead of the groove 20b extending along the ear portion 20a, a recess may be provided only around the back side of the screw hole. To fix the faucet elbow 20 to the faucet box 1, the screw 25 is inserted into the screw hole of the ear portion 20a in advance, and the O-ring 26 is attached to the screw 25 protruding from the back side of the screw hole. Thereafter, as shown in FIGS. 12 and 13, the faucet elbow 20
Is inserted into the hole 5 of the faucet box, and both ears 20a, 20a of the faucet elbow are recessed 5b, 5b on the step surface 5a of the hole.
Then, the screw 25 attached to the faucet elbow is screwed in to fix the faucet elbow 20 to the faucet box 1. Since the screw 25 is prevented from falling off by the O-ring 26, the screw 25 can be easily screwed in, and the ear portion 20a of the faucet elbow is fitted into the concave portion 5b of the step surface. It can sufficiently withstand the moment load around the axis in the front-rear direction.

After fixing the faucet elbow 20 to the faucet box 1, an O ring 17c is attached to the inner wall 32 side of the front plate 17 as shown in FIGS. 14 and 15, and an O ring 17d is attached to the faucet elbow 20. The front plate 17 is externally fitted via the above, and the hexagon nut 18 is further screwed into the faucet elbow 20 to sandwich and fix the inner wall 32 between the front plate 17 and the front plate 7 of the faucet box. The faucet box 1 is already fixed to a pillar or the like, and similarly the inner wall 32 is also fixed to a pillar or the like. However, by sandwiching the inner wall 32 between the front plate 17 and the faucet box 1, 1 is more firmly fixed to the building. Also, both O-rings 17c, 1
Due to 7d, even if water or the like is inadvertently applied to the outer surface of the inner wall 32 from the indoor side, the holes 5 of the faucet box are waterproof.
Therefore, the front plate 17 includes the small diameter portion 17a and the large diameter portion 1a.
7b and the small diameter portion 17a are formed in a crank shape in cross section and are displaced from each other in the axial direction, and the inner diameter of the small diameter portion 17a is larger than the outer diameter of the faucet mounting portion of the faucet elbow 20. The outer diameter is smaller than the inner diameter of the inner wall insertion portion 8 of the faucet elbow. However, when the protruding length of the inner wall insertion portion 8 is short, the outer diameter of the small diameter portion 17a of the front plate may be smaller than the diameter of the through hole 32a of the inner wall. Further, the inner diameter of the large diameter portion 17b of the front plate is equal to that of the faucet elbow 20.
Is formed to have a larger diameter than the outer diameter of the collar 23a of the water faucet 23 connected to. As the faucet collar, there is also a separable collar 24 as shown in FIG.

The front plate 17 has a small diameter portion 17a facing the back side and a large diameter portion 17b facing the front side.
It fits over the faucet elbow 20. Front plate 1 in FIG. 14
7, hexagon nut 18 and inner wall 32 are illustrated as follows. That is, the front plate 17 and the hexagon nut 18 show the same thing, but the inner wall 32 shows different things, the upper half part of the figure shows the plate thickness of the inner wall 32 is small, and the lower half part of the figure shows the plate of the inner wall 32. It shows when the thickness is medium. As is clear from the figure, when the inner wall 32 has a small thickness, the outer diameter of the small diameter portion 17a of the front plate fits deeply into the inner wall insertion portion 8 of the faucet box, and the inner wall 32 has a medium thickness. At this time, the faucet collar 23a is deeply fitted into the inner diameter of the large-diameter portion 17b of the front plate, and thus, the inner wall 32 of small to medium thickness can be perfectly accommodated. Further, the hexagon nut 18 is completely hidden by the large diameter portion 17b of the front plate and the flange 23a of the faucet, so that it does not spoil the aesthetics seen from the room. On the other hand, the front plate 17 in FIG.
Shows the one different from that of FIG. 14, and the hexagon nut 18
Shows the same as that of FIG. Also in FIG.
Among them, the front plate 17 and the hexagon nut 18 show the same thing, but the inner wall 32 shows different things, the upper half of the figure shows when the plate thickness of the inner wall 32 is large, and the lower half of the figure shows the inner wall 32. It shows the case where the plate thickness is very thick. That is, FIG.
As the front plate 17 used in No. 5, the displacement amount in the axial direction between the small diameter portion 17a and the large diameter portion 17b is longer than that in FIG. By using at most two kinds of front plates 17 in this way, small to medium thickness (about 9 to 15
mm) and the inner wall 32 having a plate thickness ranging from a large thickness to a large thickness (about 19 to 25 mm).
