Description

  The present invention relates to a mounting structure for a faucet joint member.

  For example, in a “wall-attached” faucet installed on a wall, a faucet joint member may be interposed between the main pipe and the faucet body. For example, as shown in FIG. 10A, a flange portion 83 is provided in the intermediate portion, a primary pipe side connection portion 81 is provided on the primary side of the flange portion 83, and a faucet side connection portion 82 is provided on the secondary side. A faucet joint member 80 having the following may be used. The faucet joint member 80 has its secondary side inserted into the mounting hole 851 of the wall portion 85, and the flange portion 83 is brought into contact with the back surface portion (back surface portion) of the wall portion 85. Then, a fixture 86 such as a fixing nut is attached (screwed) to the faucet joint member 80 from the front surface portion (front surface portion) of the wall portion 85, and the wall portion 85 is formed by the fixture 86 and the flange portion 83. By sandwiching, the faucet joint member 80 is attached to the wall portion 85.

However, in this conventional example, when the fixture 86 is attached, there is a possibility that unnecessary rotation (so-called co-rotation) may occur in the faucet joint member 80. For this reason, in order to prevent this malfunction, the rotation prevention tool is used. That is, as shown in FIGS. 10B and 10C, the anti-rotation device 87 having a U-shaped longitudinal section is disposed between the back surface of the wall portion 85 and the flange portion 83, and the flange portion 83. Are formed in an octagonal shape, a dodecagonal shape, a hexagonal shape or the like. Then, a pair of opposite end face parts 83a and 83b of the flange part 83 are sandwiched between a pair of upper and lower holding parts 87a and 87b of the rotation prevention tool 87 to prohibit the rotation of the fixing tool 86 (patent). Reference 1).
Japanese Patent Laid-Open No. 11-256634

  However, in this conventional example, the planar shape of the flange portion 83 is limited to a polygonal shape, and the degree of freedom in selecting the shape and structure of the faucet joint member 80 is reduced, and the manufacturing cost of the faucet joint member 80 is reduced. Has the problem of becoming higher.

  The present invention solves the above-mentioned problems, increases the degree of freedom in selecting the shape and structure of the faucet joint member, and reduces the manufacturing cost of the faucet joint part. The purpose is to provide a structure.

The fitting structure for a faucet joint member according to the first aspect of the invention (hereinafter simply referred to as “mounting structure”) includes a plurality of water provided with connecting portions on the primary side and the secondary side of the flange portion provided in the intermediate portion. The secondary side of the joint member for stoppers is inserted into the corresponding attachment hole of the attachment part from the back surface side to the front surface side of the attachment part, and the flange parts of the plurality of faucet joint members and The primary side is disposed on the back side of the mounting part,
While interposing an anti-rotation tool mounted across the plurality of faucet joint members, on the secondary side of each faucet joint member on the surface portion of the flange portion and on the surface portion side of the mounting portion A mounting structure configured to sandwich the mounting portion with a fixing tool to be mounted,
Each of the plurality of faucet joint members includes an engaged portion at any part from the back surface portion of the flange portion to the primary side end of each faucet joint member,
The anti-rotation device has a folded shape including a sandwiched piece portion on one end side of the folded portion and an engaging piece portion on the other end side of the folded portion,
The sandwiched piece portion is inserted through the primary side of each faucet joint member with respect to each of the plurality of insertion portions, while the front surface portion of the flange portion of the plurality of faucet joint members and the back surface of the attachment portion. While being sandwiched by the parts,
The engaging piece portion includes a plurality of engaging portions engaged with each of the engaged portions of the plurality of water faucet joint members.

In the mounting structure of the invention of claim 2, the primary side of a plurality of water faucet joint members each having a connecting portion on the primary side and the secondary side of the flange portion provided in the intermediate portion, Inserting the corresponding mounting holes from the front surface side of the mounting portion to the back surface side, and arranging the flange portion and the secondary side of the plurality of faucet joint members on the front surface side of the mounting portion,
Attached to the secondary side of each faucet joint member on the back surface side of the flange portion and the back surface side of the mounting portion with an anti-rotation tool attached across the plurality of faucet joint members A mounting structure configured to sandwich the mounting portion with a fixing tool,
Each of the plurality of faucet joint members includes an engaged portion at any part from the surface portion of the flange portion to the secondary side end of each faucet joint member,
The anti-rotation device has a folded shape including a sandwiched piece portion on one end side of the folded portion and an engaging piece portion on the other end side of the folded portion,
The sandwiched piece portion is inserted through the secondary side of each faucet joint member into each of the plurality of insertion portions, while the back surface portion of the flange portion of the plurality of faucet joint members and the mounting portion While being sandwiched by the surface portion,
The engaging piece portion includes a plurality of engaging portions engaged with each of the engaged portions of the plurality of water faucet joint members.

  In the first and second aspects of the invention, the anti-rotation device is sandwiched between the plurality of flange portions and the attachment portion and fixed to the attachment portion. And the some engaging part of a rotation prevention tool engages with the to-be-engaged part of each joint member for faucets. That is, even if any of the faucet joint members is to be rotated, this rotation is prohibited by the anti-rotation tool arranged in a fixed state and the other faucet joint members. In the inventions of claims 1 and 2, since this engaged portion is not provided on the end surface portion of the flange portion, the shape of the flange portion (planar shape) is not only a polygonal shape but also a circular shape, an elliptical shape, etc. Various shapes can be selected. Accordingly, the degree of freedom in selecting the shape and structure of the faucet joint member can be increased, and the manufacturing cost of the faucet joint portion can be reduced.

  In addition, although the manufacturing method in particular of this "water faucet joint member" is not ask | required, according to each invention, this "water faucet joint member" can be manufactured cheaply by casting, forging, etc. That is, in the conventional example shown in FIGS. 10B and 10C described above, the dimensional accuracy of the end surface portions 83a and 83b of the flange portion 83 is increased, and the end surface portions 83a and 83b and the holding portion 87a of the rotation preventing device 87 are increased. , 87b must be brought into contact with each other with high accuracy. This is because if there is no contact with high accuracy, there is a high possibility of “rattle” between the anti-rotation device 87 and the faucet joint member 80.

  However, when the faucet joint member 80 including the flange portion 83 is to be manufactured by casting, forging, or the like, a parting line is usually formed at the position of the end surface portion (83a, 83b, etc.) of the flange portion 83. . For this reason, “burrs” or the like are likely to occur in the end surface portions (83a, 83b, etc.), and it is difficult to increase the accuracy of the end surface portions (83a, 83b, etc.). Therefore, in this conventional example, it is necessary to perform secondary processing such as polishing to increase the accuracy of the end face portions (83a, 83b, etc.), or by using “other manufacturing methods” other than casting and forging. The fact is that the faucet joint member 80 is manufactured. Therefore, according to this conventional example, there is a problem that the manufacturing cost of the faucet joint member 80 increases.

  On the other hand, in the inventions of claims 1 and 2, the engaged portion is provided at a position avoiding the end surface portion of the flange portion. In other words, when manufacturing by casting, forging, etc., in order to provide the engaged portion avoiding the part where the parting line is likely to be formed, an inexpensive manufacturing method such as casting, forging, etc. Can be used actively. In addition, since it is not always necessary to perform secondary processing such as polishing on a cast product or the like, the manufacturing cost of the faucet joint member can be reduced. However, in the present invention, when the faucet joint member is manufactured by casting or forging, secondary processing such as polishing is performed, or the faucet joint member is manufactured by a manufacturing method other than casting or forging. This is not excluded.

  Examples of the “mounting portion” according to the first and second aspects of the present invention include “wall portion” and “base portion (deck portion)”. The “wall” refers to the water placed in the “faucet installation space” such as a bathroom unit, sink, and wash basin in addition to the wall of the faucet installation space such as a bathroom, washroom, and kitchen. The wall part etc. which are provided in a stopper-related article are also included. In addition, examples of the “folded portion” of the inventions of claims 1 and 2 include those having a “U-shaped cross section”, “U-shaped cross section”, “V-shaped cross section”, and the like. .

  The number of faucet joint members constituting the mounting structure of the inventions of claims 1 and 2 is not particularly limited. For example, in the case where the faucet to be applied is a hot and cold water mixing faucet, an embodiment including a “water faucet joint member” and a “water faucet joint member” can be exemplified. Examples of the “fixing member” constituting the mounting structure of the first and second aspects of the present invention include a “fixing member” that is screwed to the male screw portion or the female screw portion of the faucet joint member.

  According to a third aspect of the present invention, there is provided an attachment structure according to the first or second aspect, wherein the insertion portion is opened at a predetermined end of the sandwiched piece portion.

  According to the invention of claim 3, through the open end of the sandwiched piece part, the faucet joint member ("primary side from the flange part" in the invention of claim 1, in the invention of claim 2) "Secondary side than the flange part") can be smoothly inserted. Therefore, it is possible to perform the mounting operation of the rotation prevention tool more smoothly.

And
In the insertion portion, the width along the mounting direction of the rotation prevention tool is made larger than the width along the direction orthogonal to the mounting direction.

  In the invention of claim 4, since the insertion portion is constituted by an endless insertion hole, the sandwiched piece portion is inadvertently removed from the mounting structure after the sandwiched piece portion is sandwiched between the flange portion and the attachment portion. It will not drop out. Moreover, since the width along the mounting direction of the anti-rotation device is increased in the insertion portion, the faucet joint member (“primary side than the flange portion” in the invention of claim 1), In the invention, the “secondary side from the flange portion”) can be smoothly inserted. Therefore, according to the invention of claim 4, it is possible to perform the mounting operation of the anti-rotation device more smoothly.

  Here, the shape (planar shape) of the “insertion portion” of the invention of claim 4 is “oval”, “ellipse”, “long” with the “major axis” directed along the mounting direction of the anti-rotation device. A “rectangular rectangle” can be exemplified. In addition, on the “one end side, the other end side, or both end sides along the mounting direction of the anti-rotation device” of the basic hole portion that is formed into a circular shape or the like and is finally inserted into the faucet joint member On the other hand, the shape etc. which added the additional hole part for insertion operations, such as a rectangle, a semicircle, and a semi-ellipse, can be illustrated.

  A mounting structure according to a fifth aspect of the present invention is the mounting structure according to any one of the first to fourth aspects, wherein the engaged portion is configured by one or more smooth surfaces directed in different directions, The engaging portion is constituted by a support portion that supports each set of smooth surfaces in a contact manner from both sides.

  According to the invention of claim 5, careless rotation of the faucet joint member can be more reliably prohibited by the combination of the engaged portion with a simple structure and the engaging portion that firmly engages the engaged portion.

  The attachment structure according to a sixth aspect of the invention is the attachment structure according to any one of the first to fourth aspects, wherein one of the engaged portion and the engaging portion is constituted by a convex portion, and the other Is formed by a concave portion into which the convex portion is fitted.

  According to the sixth aspect of the present invention, inadvertent rotation of the faucet joint member can be more reliably prohibited by the combination of the engaging portion and the engaged portion having a simple configuration while firmly engaging.

  As described above, according to the present invention, the degree of freedom in selecting the shape and structure of the faucet joint member can be increased, and the manufacturing cost of the faucet joint portion can be reduced.

  Next, the best mode (hereinafter referred to as “example”) of the “mounting structure” according to the present invention will be described in detail with reference to the drawings.

  The mounting structure T of this embodiment is applied to a unit bath installed in a bathroom, as shown in FIG. That is, the mounting structure T includes two fixing members 10 for faucets (hereinafter referred to as “joint members”) 10 in the mounting portion 1 constituted by a wall surface panel, with the rotation preventing tool 30 interposed, and a fixing nut. 50 is fixed and configured. The fixing nut 50 is an example of a fixing tool. One of the two joint members 10 is a hot water joint member 10 for supplying hot water to a hot and cold water mixing faucet (not shown), and the other is for water supply for supplying water to the hot water and water mixing faucet. This is the joint member 10.

  As shown in FIG. 1, two attachment holes 1 a and 1 a are provided in a portion of the attachment portion 1 at a predetermined interval on the left and right. The mounting hole 1a on the left side is used for mounting the hot water joint member 10 to the mounting part 1, and the mounting hole 1a on the right side is for mounting the water supply joint member 10 on the mounting part 1.

The flange portion 11 has a substantially ring shape. Further, the joint member 10 is not subjected to secondary processing such as polishing, and is left in a state in which the casting surface at the time of casting is left as it is. Moreover, in the invention of each claim, unlike the present embodiment, the joint member 10 can be formed in a shape other than a substantially straight cylindrical shape. For example, an elbow-shaped cylindrical shape can be used.

  In each joint member 10, on the primary side of the flange portion 11, the outer diameter is changed in a step shape. That is, in the joint member 10, the primary side of the flange portion 11 constitutes a more primary portion and a first tubular portion 12 having a small diameter and a portion between the first tubular portion 12 and the flange portion 11. And a second tubular portion 13 having an outer diameter larger than that of the first tubular portion 12.

  The first tubular portion 12 of the hot water supply joint member 10 constitutes a hot water inflow side connecting portion to which a terminal portion (see the broken line 5 in FIG. 1) of the original hot water supply pipe is connected. The first tubular portion 12 of 10 constitutes a connection portion on the water inflow side to which a terminal portion (see a broken line 7 in FIG. 1) of the original pipe for water supply is connected. In this embodiment, a male screw portion 12a is formed on the outer peripheral surface of the first tubular portion 12 of each joint member 10, and each joint member 10 is used by using a cap nut or the like screwed to the male screw portion 12a. The first tubular portion 12 (each connecting portion) and a terminal portion of each original pipe (see the broken lines 5 and 7) are connected.

  However, the connection method of the 1st tubular part 12 (each connection part) of each joint member 10 and the terminal part (refer the broken line 5 and the broken line 7) of each original piping is not limited to this. For example, the flange portion protrudes from each outer peripheral surface of the first tubular portion 12 (each connection portion) of each joint member 10 and the terminal portion (see the broken line 5 and the broken line 7) of each original pipe, and both flange portions The two are inserted until the two come into contact with each other, and a predetermined clip is passed over the two hooks in contact with each other, thereby preventing the two hooks and thus both from being detached. You can also.

  As shown in FIGS. 1 to 4, in the second tubular portion 13 of each joint member 10, one set is formed from the two corresponding locations along the diametrical direction toward the radially outer side of the second tubular portion 13. Projecting portions 13a and 13a are formed. The protruding end surface of each protruding portion 13a is directed to the opposite direction by 180 degrees while 13b is a smooth surface, and constitutes a specific example of an “engaged portion”.

  In each joint member 10, the secondary side of the flange portion 11 is configured by a third tubular portion 15 having a larger outer diameter than the first tubular portion 12 and the second tubular portion 13. Then, the third tubular portion 15 of the hot water supply joint member 10 is connected to a hot water connection port of a hot and cold water mixing faucet (not shown) via a hot water supply connector (socket) 8 (see FIG. 1). It constitutes the connecting part on the hot water outflow side to be communicated. In addition, the third tubular portion 15 of the water supply joint member 10 is connected to a water supply connection port of a hot and cold water mixing faucet (not shown) via a water supply connector (socket) 9 (see FIG. 1). It constitutes the water outflow side connection to be communicated.

  Furthermore, as shown in FIGS. 1-4, the external thread part 15a in which the fixing nut 50 can be screwed is formed in the outer peripheral surface of the 3rd tubular part 15 of each joint member 10. As shown in FIG.

  As shown in FIGS. 1 to 4, the rotation preventing tool 30 is configured by a plate-like body having a substantially U-shaped longitudinal section. That is, the anti-rotation tool 30 includes a folded portion 31 configured in a substantially U-shaped folded shape, a sandwiched piece portion 32 provided on one end side of the folded portion 31, and the other end side of the folded portion 31. And an engagement piece portion 33 provided. Further, in the rotation preventing tool 30, the folded portion 31 is positioned above, and the sandwiched piece portion 32 and the engaging piece portion 33 are suspended from each end of the folded portion 31.

  The sandwiched piece portion 32 includes two insertion portions 32a and 32a on the left and right sides so as to penetrate the front and back sides. The two insertion portions 32a and 32a are formed at the same pitch as the “two attachment holes 1a and 1a” of the attachment portion 1 described above, and are released at the lower end portion 32d of the sandwiched piece portion 32. Yes. That is, these insertion portions 32 a and 32 a have a “notch shape” released at the lower end portion 32 d of the sandwiched piece portion 32. Moreover, each insertion part 32a can be inserted in the state which maintained the predetermined clearance in the part (namely, 3rd tubular part 15) of the secondary side rather than the flange part 11 of each joint member 10. FIG. In addition, the lower end part 32d of the to-be-clamped piece part 32 comprises the specific example of the "end part" of the invention of Claim 3.

  The engagement piece portion 33 includes “two support portions 33a and 33a” on the left and right sides in a state of penetrating the front and back surfaces. The two support portions 33a and 33a are formed at the same pitch as the “two mounting holes 1a and 1a” of the mounting portion 1 described above, and are released at the lower end portion 33d of the engagement piece portion 33. . That is, these support portions 33a are also “notched” released at the lower end portion 33d. Each support portion 33a constitutes a specific example of the engaging portion.

  As shown in FIG. 5A, each support portion 33a has a pair of gripping surfaces 33f and 33f facing each other in a substantially vertical state. The distance between the pair of gripping surfaces 33f and 33f is substantially equal to the distance between the pair of protruding end surfaces provided on each second tubular portion 13 and 13b. Therefore, when each second tubular portion 13 is inserted between the pair of gripping surfaces 33f and 33f constituting each support portion 33a, the pair of gripping surfaces 33f and 33f abut the pair of protruding end surfaces and 13b and 13b. Support in the state. As a result, each support portion 33a has a structure that supports each second tubular portion 13, and thus each joint member 10, while prohibiting rotation about its axis.

  The above attachment structure T is constructed as follows, for example. That is, each joint member 10 is mounted in each mounting hole 1a from the back surface portion 1d side of the mounting portion 1 with the rotation preventing tool 30 interposed. At this time, the “secondary portion of the flange portion 11 (that is, the third tubular portion 15)” of each joint member 10 is inserted into the insertion portion 32a, and a pair of protruding end faces 13b and 13b are formed by the support portion 33a. Is supported in a contact state. In this state, the third tubular portion 15 of each joint member 10 is inserted from the back surface portion 1d side of the mounting portion 1 to the front surface portion 1e side, and the distal end portion of the third tubular portion 15 (secondary side of the joint member 10).

Thereby, the to-be-clamped piece part 32 is lightly clamped by the surface part 11c of the flange part 11, and the back surface part 1d of the attachment part 1. FIG.

  Next, the fixing nut 50 is attached (screwed) by hand tightening to a portion exposed to the surface portion 1e side of the mounting portion 1 in the male screw portion 15a of the third tubular portion 15. Thereafter, the left and right fixing nuts 50 are tightened alternately little by little using a tool, and the fixing nut 50 disposed on the front surface portion 1e of the mounting portion 1 and the flange portion disposed on the back surface portion 1d of the mounting portion 1 When the clamped piece portion 32 and the mounting portion 1 are firmly clamped by the surface portion 11c of the eleventh, the attachment of each joint member 10 is completed.

  Note that “tightening of the left and right fixing nuts 50” is performed alternately, but when one of the fixing nuts 50 is tightened, one of the joint members 10 to which the one fixing nut 50 is attached rotates. It is supported by the prevention tool 30. And since this rotation prevention tool 30 is supported by "the other joint member 10" and "the other fixing nut 50" attached to this, the rotation of the "one joint member 10" is supported. Is prohibited.

  According to the present embodiment, the anti-rotation device 30 is sandwiched between the plurality of flange portions 11 and the attachment portion 1 and fixed to the attachment portion 1. Then, the plurality of engaging portions (supporting portions 33) of the rotation preventing tool 30 engage with the joint member 10 with the engaged portion (protruding end surface 13a). In other words, even if one of the joint members 10 is to be rotated, this rotation is prohibited by the rotation preventing tool 30 arranged in a fixed state and the other joint member 10. In this embodiment, since the engaged portion (protruding end surface 13a) is provided avoiding the end surface portion of the flange portion 11, various shapes can be selected as the shape (planar shape) of the flange portion 11. Therefore, the degree of freedom in selecting the shape and structure of the joint member 10 can be increased, and the manufacturing cost of the joint member 10 can be reduced.

  Further, according to the present embodiment, the joint member 10 can be manufactured at low cost by casting, forging or the like. That is, in the present embodiment, the engaged portion is located at a position avoiding the end face portion of the flange portion 11 (that is, a portion where a parting line is usually avoided when manufacturing by casting or forging). (Protruding end surface 13a) is provided. Therefore, an inexpensive manufacturing method such as casting or forging can be actively used. In addition, since the secondary processing such as polishing is not necessarily performed, the manufacturing cost of the joint member 10 can be reduced.

  Further, in the present embodiment, the insertion portion 32 a has a “notch shape” opened at the lower end portion 32. Therefore, the primary side of the joint member 10 can be smoothly inserted into the insertion portion 32a through the opened lower end portion 32.

In this insertion part 36, as shown in FIG. 9, the width a along the mounting direction of the anti-rotation device 30 (the vertical direction is illustrated in this modification) is set to a direction orthogonal to the mounting direction (left and right in this modification). It is desirable to make it larger than the width b along the direction method.

  In the third modification shown in FIG. 9, since the insertion portion 36 is configured by an endless insertion hole, the sandwiched piece portion 32 is sandwiched after being sandwiched between the flange portion 11 and the attachment portion 1 of the joint member 10. The piece 32 is not inadvertently dropped from the mounting structure. In addition, when the width a along the mounting direction of the rotation preventing tool 30 (the vertical direction in this modification) of the insertion portion 36 is increased, the primary side portion of the joint member 10 can be smoothly inserted into the insertion portion 36. Therefore, the mounting work of the rotation preventing tool 30 can be performed more smoothly.

  The present invention can be used, for example, in the field of manufacturing, selling, installing, processing and the like of faucets.
