Description

  The present invention relates to a structure for assembling a faucet member and a faucet member.

Some faucet members allow a water passage member (a member for water passage) to be inserted therethrough. For example, in a shower stand for supporting a shower head, a shower body for passing water to the shower head in a stand body (a specific example of a faucet member) configured in a pipe shape. There is one in which a hose (a specific example of a water-permeable member) is inserted (see Patent Document 1).
Japanese Patent Laid-Open No. 10-237911

  By the way, in this kind of faucet member, the water transmitted from the shower head may travel along the outer periphery of the water passage member and enter the faucet member. For this reason, this applicant tried the following improvements in the faucet provided with this kind of faucet member. That is, as shown in FIG. 11, an open hole 83 that opens the internal space 81 of the stand body (water faucet member) 80 downward is formed in the lower part of the peripheral wall portion of the stand body (water faucet member) 80. To do.

  Further, a support member 85 having an insertion space portion 85a in the axial direction is prepared. The support member 85 includes a drain hole 85b that opens the insertion space portion 85a downward in an intermediate portion along the axial direction. In addition, mounting portions 85c and 85d are provided on both sides of the drain hole 85b in the outer peripheral portion. Then, the shower hose 5 is inserted into the insertion space 85a so that it can be pulled out, and the support member 85 is mounted in a state in which the seal members (packings) 86a and 86b are attached to both the attachment portions 85c and 85d. It is inserted into the internal space 81 of the stand main body (water faucet member) 80. At this time, when the drain hole 85b and the opening hole 83 are aligned in the vertical direction, the water that has entered the stand main body 80 through the shower hose 5 is passed through the drain hole 85b and the opening hole 83 in this order. Can be discharged outside.

  However, when this type of faucet member (stand body 80, support member 85) is assembled, the following problems occur. That is, the open hole 83 is generally formed later by machining (cutting or the like) on a faucet member formed by casting or resin molding. For this reason, a portion of the inner peripheral portion 87 of the faucet member (stand main body 80) located around the open hole 83 is subjected to machining by “unnecessary protrusions (“ burrs ”or“ burrs ”) 88. May occur. In addition, although it is conceivable that the faucet member is integrally formed with an opening hole 83, in this case, the portion located around the opening hole in the inner peripheral portion of the faucet member is also included. Unnecessary protrusions may be produced.

  Therefore, in the process of assembling the other faucet member (support member 85) to the faucet member (stand body 80) provided with the open hole 83, the seal disposed behind the open hole 83. The member (packing) 86 b comes into contact with the protrusion 88. Then, there is a possibility that the seal member (packing) 86b may be damaged (cut, scratched, etc.).

  The present invention solves the above-mentioned problem, and when a “water faucet member with an open hole” is assembled to a “water faucet member having an open hole”, the seal member is damaged. It is an object to provide a faucet member assembling structure and a faucet member for constituting such an assembling structure, which can prevent occurrence of damage or reduce the possibility of breakage. .

The assembly structure of the faucet member of the invention of claim 1
While inserting the insertion part which constitutes a part or the whole of the second faucet member into the assembling space part having a substantially circular space cross section in the assembling part provided in the first faucet member A faucet member assembly structure, wherein the second faucet member is assembled to the first faucet member,
In the assembling portion, the axial center of the assembling space portion is horizontal or inclined, and the assembling space portion is opened to the outside at a predetermined position along the direction of the axial center. An open hole is formed,
Of the outer peripheral portion of the insertion portion, a back side mounting portion is provided in a circular shape in a portion to be inserted deeper than the formation position of the open hole in the assembly portion,
A seal member for forming a watertight part between the outer peripheral part of the insertion part and the inner peripheral part of the assembly part is attached to the back side mounting part,
The back side mounting portion includes a circular path including an arc-shaped portion along the circumference of a virtual reference circle and a relief portion located inside the circumference of the reference circle,
The arcuate portion is arranged in a portion located on the lower side in the assembling space.

  According to the first aspect of the invention, the shape of the cross section of the assembling space (the shape of the cross section perpendicular to the axis of the assembling space) is substantially circular. That is, since the assembling space portion has a substantially cylindrical shape or the like, the insertion portion can be rotated around its axis within the assembling space portion. Moreover, in the first aspect of the invention, the back side mounting portion uses a part of the circular path as a relief portion. In other words, the shape of the path drawn by the back side mounting portion is not a circular shape, but a shape in which a part of the circular shape is recessed in the center direction. For this reason, when the seal member is attached (externally fitted) to the back side mounting portion, the outer peripheral portion of the seal member has a shape that follows the path of the back side mounting portion. Specifically, the outer peripheral portion of the seal member also has a shape including an arc-shaped portion and a relief portion.

  For this reason, in the invention of claim 1, by performing the insertion operation of the insertion portion as follows, for example, the seal member attached to the back side attachment portion is prevented from being damaged or is damaged. The possibility can be lowered. That is, when the seal member (the back side mounting portion) passes through the open hole (when passing through the space cross section in which the open hole is formed in the assembling space portion), the back side mounting portion and the open hole In the meantime, an artificial “positional deviation (positional deviation along the radial direction of the assembling space)” is generated. As a result, the seal member can be prevented from coming into contact with protrusions (burrs, burrs, etc.) around the open hole, or the possibility of contact can be reduced. Then, after the seal member (the back side mounting portion) passes through the open hole, the “artificial misalignment” between the insertion portion and the assembly portion may be eliminated.

  In the present invention, since a part of the seal member mounted on the back side mounting portion is an escape portion, this seal member does not seal the entire outer periphery thereof. However, since the inside of the assembly space portion is opened to the atmosphere by the opening hole, as described above, “even if a relief portion is provided in a part of the seal member (that is, there is a portion where sealing is not performed). The sealing performance necessary for the assembly structure of the faucet member is ensured.

  In the invention of each claim, the first faucet member may be composed only of the assembly part, or the first faucet member may be composed of the assembly part and another part. Moreover, even if the 2nd faucet member is comprised only by the insertion part, the 2nd faucet member may be comprised by the insertion part and another part.

  In the invention of each claim, the purpose of forming the “open hole” is not particularly limited. For example, this “open hole” is formed as “a drainage outlet for draining water that enters the assembly structure (inside the assembly space) to outside the assembly structure (outside the assembly space)”. The case can be illustrated. In addition, in the inventions of claims 1 to 5, “in the assembling portion, the lower part of the predetermined position along the axial direction of the assembling space portion” means, for example, “an assembling space in the assembling portion. Among the intermediate portions along the direction of the axial center of the portion, the lowermost end portion along the direction of circling the inner peripheral portion of the assembly portion can be exemplified. In addition, the “open hole” of the first to fifth aspects of the invention is not limited to the “lower part”, but may be provided in “a part including the lower part and wider than the lower part”. That is, it may be provided in “an arc-shaped portion along the direction of circling the inner peripheral portion of the assembly portion while including the lowermost end portion”.

  In the invention of each claim, the method of forming the “open hole” is not particularly limited, and for example, cutting can be exemplified. In particular, when drilling is performed by machining using a cutting tool (such as a drill) from the outside of the assembly part, “in the inner peripheral part of the assembly part, around the open hole” Since protrusions such as “burrs” are likely to occur, the invention of each claim becomes more meaningful.

  In the invention of each claim, examples of the specific shape of the “circular path drawn by the back side mounting portion” include the following shapes. That is, (1) a path shape including an arc-shaped portion along the circumference of a virtual reference circle and a linear portion (string-shaped portion) connecting between ends of the arc-shaped portion (particularly, (D-shaped), (2) The arc-shaped portion along the circumference of the virtual reference circle and the end of the arc-shaped portion are connected and located inside the circumference of the virtual reference circle. A path shape including a curved portion (a concave curved portion) can be exemplified. In the invention of each claim, `` the part along the circumference of the virtual reference circle in the back side mounting part '' makes the seal member contact the inner circumference of the assembly part in a watertight manner, The sealing member is a portion that performs sealing, and the relief portion is a portion that makes the sealing member non-contact with the inner peripheral portion of the assembly portion.

  In the invention of each claim, when the "circular path drawn by the back side mounting portion" is composed of one arc-shaped portion and a relief portion connecting between ends of the arc-shaped portion, It is desirable that the “center angle of the arcuate portion” be any one of 60 degrees to 350 degrees. When the central angle is less than 60 degrees, the sealing range by the sealing member becomes too small, and the sealing ability of the sealing member becomes insufficient. On the other hand, if the angle exceeds 350 degrees, the outer peripheral portion of the seal member may become a perfect circle despite the presence of the escape portion in the back side mounting portion. The “center angle of the arcuate portion” is more preferably any one of 120 degrees to 340 degrees, still more preferably any one of 180 degrees to 320 degrees, and 200 degrees to 300 degrees. Even more preferably, any of the degrees.

  In addition, in invention of Claims 1-5, "the site | part located in the downward side in the space part for an assembly | attachment" is "in the space part for an assembly | attachment," for example in the direction which goes around the inner peripheral part of an assembly | attachment part. A portion located on the lowermost end side along the side ”can be exemplified. That is, in the inventions of claims 1 to 5, the arc-shaped portion is disposed in this “lowermost end portion” or “a part wider than the lowermost end portion including the lowermost end portion”.

  In the invention of each claim, the insertion portion includes a plurality of “back side mounting portions”, and each “back side mounting portion” includes “an arcuate portion along the circumference of a virtual reference circle, A circular path provided with a relief portion located inside the circumference of the reference circle may be provided. Further, in the invention of each claim, the insertion portion is a “mounting portion” other than the “back side mounting portion”, that is, “outside the outer peripheral portion of the insertion portion, than the formation position of the open hole in the assembly portion. In addition, a circular mounting portion (hereinafter referred to as “inlet side mounting portion”) may be provided in “the portion to be inserted on the inlet side (the inlet side of the assembly portion)”. This “entrance-side mounting part” may have a circular (true circular) circular path ”or“ circular path (arc-shaped part, relief part) similar to the “back-side mounting part” May be provided.

  The invention of claim 2 exemplifies specific contents of the first faucet member and the second faucet member. That is, the insertion portion allows the water discharge hose to be pulled out and inserted, and constitutes a holding member (storage member) that holds (stores) the water discharge hose. And the aspect which comprises the supporting member (for example, stand main body) which supports "the insertion part holding the water discharge hose" by the 1st faucet member or one part is illustrated.

  In the invention of claim 2, the water that enters the assembly space through the water discharge hose enters the insertion space and drains out of the insertion space through the drainage. At this time, the seal member mounted on the back mounting portion is in watertight contact with the lower side of the inner peripheral portion of the assembly portion on the back side of the assembly space portion rather than the drainage portion, and the insertion space portion The water drained to the outside is blocked and prevented from entering further below the assembling space. And the water blocked by this seal member is discharged to the outside of the assembly part (first faucet member) through the open hole. In other words, the seal member mounted on the back side mounting portion “drains” the water transmitted through the water discharge hose and drains it outside the assembly portion (first faucet member). ”.

  Here, the water discharge hose refers to a hose interposed between a water supply source (a faucet body, a terminal portion of the original piping, or a water heater) and a “water discharge tool”. In addition, this "water discharge tool" is not limited to a shower head for performing shower water discharge, and includes a water discharge head for performing various forms of water discharge (normal water discharge, foam water discharge, etc.). Further, when the water discharge hose is inserted into the insertion space portion and pulled out or inserted (stored), the water discharge hose slides with the inner peripheral portion (the inner peripheral portion surrounding the insertion space portion). It is good to do.

Is configured. And this 2nd mounting part 33 comprises the specific example of a back side mounting part.

  As shown in FIG. 6A, the second mounting portion 33 includes a circular path 33k including an arc-shaped portion 33e and a chord-shaped portion 33g. Here, the string-like portion 33g constitutes a specific example of the escape portion. In addition, the arc-shaped portion 33e is a virtual reference circle (a circular circle drawn by this path when the second mounting portion 33 assumes a perfect circle path) C. It is a part formed in circular arc shape along. The chordal portion 33g is a portion connecting both ends of the arc-shaped portion 33e, and is located inside the circumferential portion of the aforementioned “virtual reference circle C”. In this embodiment, the central angle A of the arc-shaped portion 33e is set to about 270 degrees.

  As shown in FIG. 6B, a second seal member (packing) 50 is mounted on the second mounting portion 33 in an outer fitting shape. Thus, the second seal member 50 uses its own elasticity to crimp the inner peripheral portion 50a to the second mounting portion 33, and the left and right side peripheral portions (not shown) are opposed to the opposing flange portion 33a. Crimp.

  As described above, when the second seal member 50 is attached (externally fitted) to the second attachment portion (back side attachment portion) 33, the outer peripheral portion 50b of the second seal member 50 is attached to the second attachment portion. The shape follows the path of the portion (back side mounting portion) 33. Specifically, the outer peripheral portion 50b of the second seal member 50, which has been a perfect circle before mounting, is attached to the “arc-shaped portion 33e after mounting on the second mounting portion (back side mounting portion) 33. The arcuate part E "following" and the string-like part (relief part) G following the string-like part 33g ".

  When the second seal member 50 is mounted on the second mounting portion (back side mounting portion) 33, the arc-shaped portion E constituting the outer peripheral portion 50b of the second seal member 50 is formed by the flange portions 33a and 33a. It is in a state of projecting further in the radially outward direction of the main body 31 than the projecting end 331a. In FIG. 6B, for convenience of explanation, the positional relationship between the outer peripheral portion 50b of the second seal member 50 and the protruding end portion 331a of the flange portion 33a is exaggerated (the outer peripheral portion 50b). The protruding amount from the protruding end portion 331a is exaggerated. Further, the chord-like part (relief part) G constituting the outer peripheral part 50b of the second seal member 50 is retracted in the radially inward direction of the main body part 31 from the projecting end part 331a of both flange parts 33a, 33a.

The engagement legs 35 can cause elastic deformation (bending) in the radially outer direction and the radially inner direction of the main body 31 in a state where the rear end surface of the main body 31 is a fixed end.

  In the above assembly structure K, each member (the stand main body 20, the support member 30) is assembled in the following procedure, for example. First, the first seal member 40 is mounted on the first mounting portion 32, and the second seal member 50 is mounted on the second mounting portion (back side mounting portion) 33. And after inserting the shower hose 5 in the insertion space part 31a, the support member 30 is inserted in the assembly space part 25a.

  The operation of inserting the support member 30 into the assembling space 25a is performed by aligning the rear end portion of the support member 30 coaxially and obliquely above the upper end portion 22 of the stand main body 20, and further supporting the support member 30. This is started in a state where the shaft is rotated 180 degrees (hereinafter referred to as “inversion state”) (see FIG. 7). The “reversed state” is “a state in which the support member 30 is rotated 180 degrees around the axis center based on the final assembled state”. In this inverted state, as shown in FIG. 8, the chordal portion 33g of the second mounting portion (back side mounting portion) 33 and the chordal portion G of the outer peripheral portion 50b of the second seal member 50 are disposed below. It will be in the state. Moreover, it will be in the state by which the engagement leg 35 was arrange | positioned upwards.

  Then, in this inverted state, the insertion amount of the support member 30 into the assembling space 25a is increased, and the second seal member 50 and the second mounting portion (back side mounting portion) 33 are moved to the open hole 26. Work to reach the back side of the formation location of. In this operation, as described above, the chordal portion G of the outer peripheral portion 50b of the second seal member 50 is disposed below, and the chordal portion G and the inner peripheral portion 25b of the assembling portion 25 are arranged. An empty space 25c is formed between the two. For this reason, as shown in FIG. 8, in the inner peripheral portion 25 b of the assembly portion 25, a protruding portion (unwanted protruding portion) B such as a burr is formed at a portion located around the opening hole 26. However, the contact between the outer peripheral portion 50b of the second seal member 50 and the protruding portion B can be avoided.

  The insertion amount of the support member 30 into the assembling space 25a is further increased, and the “rear portion of the front side of the flange portions 32a and 32a on both sides of the first mounting portion 32” The insertion of the support member 30 is completed when it comes into contact with the stepped portion 22d of the upper end portion 22 of the main body 20. Then, the support member 30 is rotated by 180 degrees around its axis, so that the state of the support member 30 becomes the original state. That is, the chordal portion 33g of the second mounting portion (back side mounting portion) 33 and the chordal portion G of the outer peripheral portion 50b of the second seal member 50 are placed in the upper state, and the engaging leg 35 is placed. Is placed below. Then, the rotation amount of the support member 30 is adjusted so that the engaging protrusion 35 b of the engaging leg 35 is aligned with the engaged hole 27, and the engaging protrusion 35 b is aligned with the engaged hole 27. When the engagement protrusion 35b is engaged with the engaged hole 27, the assembly of the support member 30 to the stand main body 20 is completed (see FIG. 2). At this time, positioning of the support member 30 to the stand main body 20 and fixation of the support member 30 to the stand main body 20 can be performed.

  As described above, after the assembly of the support member 30 to the stand main body 20 is completed, the shower hose 5 is pulled out of the stand main body 20 and stored in the stand main body 20. Further, when the assembly of the support member 30 to the stand main body 20 is completed, an opening portion 31 d formed below is disposed above the opening hole 26 in the outer peripheral portion of the main body portion 31.

  Further, in the inner peripheral portion 25b of the assembly portion 25, the chordal portion G of the “second seal member 50” is disposed at the upper side in the portion on the back side of the formation position of the opening hole 26. In the “rear part”, a part of the upper side is not sealed. However, the inside of the assembling space 25 a is open to the atmosphere by the opening hole 26. In addition, in this “back side part”, a wide part centering on the lower part side is sealed using the “second seal member 50”. For this reason, in the assembly structure K, the required sealing performance is ensured.
