Description

  The present invention relates to a faucet component mounting structure in which a faucet component such as an elbow or a faucet is attached to an adapter that is connected to a water supply pipe, a hot water supply pipe, and the like and that is mounted and fixed to a mounting portion such as a wall surface.

2. Description of the Related Art Conventionally, there has been known a faucet part mounting structure in which a faucet part such as an elbow or a faucet is attached to an adapter that is connected to a water supply pipe, a hot water supply pipe, or the like and attached to a mounting surface such as a wall. For example, FIG. 4 shows an example of the mounting structure of the faucet part. The faucet component attachment structure 60 is attached and fixed to a wall surface 1 of a bathroom (not shown) which is an example of an attachment portion, and a mist shower 5 capable of discharging a mist-like mist shower is attached to an upper portion of the box 6. It is attached and fixed inside. In this mounting structure 10, a substantially cylindrical adapter 12 whose back end side is connected to a pipe (not shown) drawn to the back side of the wall surface 1 is fixedly mounted. Further, a flange portion 14 is provided around the tip of the adapter 12, and the adapter 12 is attached and fixed to the wall surface 1 by a nut 18 and a flange portion 14 screwed to the adapter 12 from the front side of the wall surface 1. . An elbow 62 that is an example of a faucet component is attached and fixed to the tip of the adapter 12. The first connection portion 64 of the elbow 62 connected to the adapter 12 side is engraved with a male screw, which is a taper screw formed slightly tapered. On the other hand, the adapter 12 is engraved with a parallel female screw into which the taper screw of the first connection portion 64 is screwed. Then, the sealing tape 66 is wound around the taper screw of the elbow 62 to ensure the watertightness between the adapter 12 and the elbow 62, and the elbow 62 is screwed into the adapter 12 until the elbow 62 cannot be screwed any further. Thus, the screwing and positioning of the elbow 62 with respect to the adapter 12 are completed (see, for example, Patent Document 1).
JP 2002-266391 A (FIG. 3)

  However, the above-described conventional mounting structure has a problem that the distance (so-called “protruding dimension”) of the elbow 62 from the wall surface 1 slightly varies depending on the screwing amount of the elbow 62 with respect to the adapter 12. As described above, in the mounting structure 10 in which the sealing tape 66 is wound around the taper screw and the female screw of the adapter 12 and the male screw of the elbow 62 are connected so as to achieve watertightness, the screwing amount of the taper screw is adjusted by the number of windings of the seal tape 66. However, adjusting the protruding dimension of the elbow 62 according to the number of windings of the seal tape 66 in this way requires highly skilled techniques. Therefore, it has been very difficult to accurately determine the protruding dimension of the faucet component to be connected using a taper screw. If the distance from the faucet component to the mounting portion is not constant in this way, for example, as shown in FIG. 4, when the adapter 12 and the elbow 62 are connected, the distance from the wall surface 1 is assumed in advance. Therefore, it is difficult to align the end of the box 6 and the wall surface 1 whose dimensions are determined, and a gap is generated between the end of the box 6 and the wall 1, or the end of the box 6 is If it was going to position with respect to 1, the problem that the connection of the adapter 12 and the elbow 62 would become difficult had arisen.

  In addition, since the attachment portion such as the wall surface 1 to which the adapter 12 is attached and fixed is appropriately selected at the site where the adapter 12 is installed, its thickness often varies depending on the type of the attachment portion to be installed. Moreover, even if it is the same kind of attaching part, the thickness may differ slightly. As described above, in the conventional mounting structure 10, the faucet parts such as the elbow 62 are positioned at a fixed position with respect to the adapter 12, so that the mounting located on the front surface of the collar portion 14 of the adapter 12 is performed. If the thicknesses of the portions are different, the distance from the faucet component to the mounting portion (“outward dimension”) will be different even when attached to the same adapter 12. Thus, even when the thickness of the attachment portion is varied, the distance from the faucet part to the attachment portion is not constant, and for example, as shown in FIG. 4, the distance from the wall surface 1 is assumed in advance. There has been a problem that it is difficult to align the end of the box 6 whose dimensions are determined and the wall surface 1 with each other.

  In addition, the positioning of the wall surface 1 and the box 6 as shown in FIG. 4 is not limited to a problem. For example, when a shower hose is attached to the tip of a rotatable elbow, Since the distance between the plug part and the mounting part is narrower than the distance assumed in advance, the shower hose interferes with the mounting part and hinders the operability of the shower. There was also a problem that affected.

  The present invention solves the problems of the above-mentioned conventional water faucet, the interval between the water faucet component attached to the adapter and the mounting portion can always be constant, the faucet component side installation and use, etc. It aims at providing the attachment structure of the faucet part which does not have trouble.

  In order to solve the above problems, means taken by the present invention will be described below. The mounting structure of the faucet part of the present invention is “a faucet part for attaching a faucet part such as an elbow or a faucet to an adapter connected to a water supply pipe / hot water supply pipe and the like and attached to a mounting part such as a wall surface”. In the mounting structure, the adapter includes a flange portion in which a screw hole is screwed, and a male screw portion that is provided on the distal end side of the adapter with respect to the flange portion and to which a nut can be screwed.

A structure for mounting a faucet part. "(Claim 1).

  In the mounting structure of the present invention, a cylindrical part inserted and connected to the adapter is provided in the faucet part, and the faucet part is screwed to the collar part of the adapter. Therefore, the positioning of the faucet part relative to the adapter can be adjusted by adjusting the insertion amount of the cylindrical portion. Therefore, the faucet parts can always be accurately positioned at a fixed interval with respect to the mounting portion such as the wall surface. In the present invention, the “water faucet part” refers to various parts related to the faucet, such as faucets such as a stop cock, joints, elbows, and piping.

The elbow 20 includes a first connection portion 22 connected to the adapter 12 side, and a second connection portion 24 connected to a faucet (not shown) on the side opposite to the first connection portion 22. The first connecting portion 22 and the second connecting portion 24 are arranged so that their axes are substantially orthogonal, and the overall shape of the elbow 20 is formed in an approximately L shape.

  The first connection portion 22 is formed in a substantially cylindrical shape, and a cylindrical portion 26 to be inserted into the insertion portion 17 of the adapter 12 is provided on the distal end side thereof. The cylindrical portion 26 has an outer shape substantially the same as the inner diameter of the insertion portion 17, and has two circumferential grooves 30 with O-rings 28 mounted on the outer peripheral surface thereof. Watertightness with the cylindrical portion 26 is achieved. Further, on the outer peripheral surface on the far end side of the cylindrical portion 26 of the first connection portion 22, when the cylindrical portion 26 is inserted into the insertion portion 17 by a predetermined amount or more, it contacts the distal end portion of the insertion portion 17. A locking ridge 31 that contacts and locks the cylindrical portion 26 is provided.

  Moreover, as shown in FIG. 2, the ear | edge part 32 is protrudingly provided in the both sides of the outer peripheral surface which pinched | interposed the axial center of the 1st connection part 22, respectively. The ear portion 32 has a base portion 34 that protrudes so as to rise from the outer peripheral surface of the first connection portion 22, and a contact portion that is bent and connected from the tip end of the base portion 34 to the tip end side of the first connection portion 22. 36. The contact portion 36 is provided with an insertion hole 38 through which the screw 3 is screwed and the tip of the screw 3 can protrude toward the tip side of the contact portion 36. An insertion hole 4 through which the screw 3 protruding from the contact portion 36 is inserted is provided at the periphery of the mounting hole 2 of the wall surface 1.

  Next, how to attach the faucet component mounting structure 10 will be described. First, the male screw portion 16 of the adapter 12 is inserted into the mounting hole 2 from the back side of the wall surface 1 to expose the tip of the male screw portion 16 to the front surface side of the wall surface 1. Next, the nut 18 is fastened to the male screw portion 16 from the front side of the wall surface 1. At this time, alignment is performed so that the screw hole 19 of the flange 14 matches the insertion hole 4 of the wall surface 1. Next, the cylindrical portion 26 of the first connection portion 22 of the elbow 20 is inserted into the insertion portion 17 in the male screw portion 16 of the adapter 12, and inserted until the contact portion 36 of the ear portion 32 contacts the wall surface 1. To do. Then, the elbow 20 is accurately positioned with respect to the wall surface 1 in a state where the contact portion 36 is in contact with the wall surface 1.

  Further, the screws 3 are screwed into the ear portions 32 to be inserted through the insertion holes 4 of the wall surface 1, and the screws 3 are screwed into the screw holes 19 of the flange portion 14 of the adapter 12 arranged on the back side of the wall surface 1. 20 is fixed to the wall surface 1 and the adapter 12. At this time, the nut 18 may be further tightened to fix the adapter 12 to the wall surface 1 more firmly.

  In the mounting structure 10 configured as described above, the positioning of the elbow 20 with respect to the wall surface 1 is provided so as to be always constant according to the height of the contact portion 36. In the example shown in FIG. 2, a gap is provided between the distal end surface of the male screw portion 16 of the adapter 12 and the base portion 34 of the ear portion 32 of the elbow 20. For example, the thickness of the wall surface 1 is an example shown in FIG. 2. In the case where the thickness is thinner than the example shown in FIG. 2, the cylindrical portion 26 is further inserted on the back side of the insertion portion 17 so that the contact portion 36 contacts the wall surface 1. On the other hand, when the wall surface 1 is thicker than the example shown in FIG. 2, the abutting portion 36 is positioned with the cylindrical portion 26 positioned closer to the insertion portion 17 opening side than the example shown in FIG. 2. Is brought into contact with the wall surface 1 to position the elbow 20 with respect to the wall surface 1. Thus, even if the thickness of the wall surface 1 changes, the positioning of the elbow 20 with respect to the wall surface 1 (adjustment of the protruding dimension) can be performed very easily. In addition, since the positioning can be performed by inserting the cylindrical portion 26 until the abutting portion 36 abuts against the wall surface 1, extremely accurate positioning can be performed including the case where the thickness of the wall surface 1 is slightly different. Even when positioning is adjusted in this way, the water tightness between the insertion portion 17 and the cylindrical portion 26 is always ensured by the O-ring 28 attached to the circumferential groove 30 of the cylindrical portion 26. .
