Summary of the Invention

Problems to be Solved by the Invention

[0006] The upper insulator has a flange portion intervening between the flat washer and the flange portion of the saddle. Thereby, the upper insulator can prevent the occurrence of corrosion due to the peeling of the coating of the saddle by the flat washer when the nut is tightened.

[0007] However, during the operation of attaching the saddle-type water tap described in Patent Document 1 to the water distribution pipe, the flat washer is not positioned until the shaft portion of the bolt is inserted through the flat washer. Therefore, there is a risk that the flat washer may fall during the operation, or that the flat washer may come into contact with the shaft portion of the bolt and fall when the shaft portion of the bolt is inserted through the flat washer. Since the operation of attaching the saddle-type water tap to the water distribution pipe is carried out in a narrow and dark place where the road surface or the like is excavated, if the flat washer falls, the flat washer may be lost, or mud, sand, etc. may adhere to the flat washer, resulting in a decrease in workability.

Modes for Carrying Out the Invention

[0012] (First Embodiment) With reference to FIGS. 1 to 6, a saddle valve 100 according to an embodiment of the present invention will be described. When explaining the directions, the side of the saddle valve 100 shown in FIG. 1 is referred to as the upper side, and the side of the pair of bolts B1 and nuts N1 is referred to as the left and right sides for explanation. Note that since the saddle-type water faucet 100 is formed in a bilaterally symmetric shape as a whole except for the male screw portion 1e for connecting the water supply pipe of the faucet body 1 and the plug rod 13, mainly one side on the left and right will be described and the description of the other side will be omitted as appropriate. Also, components with the same configuration will be given the same reference numerals and their descriptions will be omitted.

[0013] <Saddle-type water faucet> As shown in FIGS. 1 and 2, the saddle-type water faucet 100 is a water faucet used to branch a water supply pipe (not shown) for supplying water from a metal or resin water distribution pipe P1 such as a main water pipe to each house or the like. The saddle-type water faucet 100 includes a faucet body 1, a saddle 2 having flange portions 2b on the left and right, a band 3 having flange portions 3b on the left and right, a pair of bolts B1, and nuts N1 screwed onto the pair of bolts B1 respectively. The saddle 2 is joined to the faucet body 1. In other words, the saddle-type water faucet 100 mainly includes a water stop mechanism 10 provided in the faucet body 1 and a saddle mechanism 20 having the saddle 2, the band 3, the pair of bolts B1, and the pair of nuts N1. The saddle-type water faucet 100 is used in appropriately sized and shaped versions according to the material and diameter of the water distribution pipe P1.

[0014] The bolt B1 is inserted through the bolt insertion hole 3c of the flange portion 3b of the band 3 with the lower insulator 6 attached, the bolt insertion hole 2c of the flange portion 2b of the saddle 2 with the upper insulator 5 attached, and the flat washer 8 in sequence and screwed with the nut N1. By tightening the nut N1 screwed onto the bolt B1, the saddle-type water faucet 100 is attached to the outer periphery of the water distribution pipe P1.

[0015] <Faucet body> The water distribution plug body 1 is a housing that forms the outer case of the water stop mechanism 10. The water distribution plug body 1 has a vertical hole 1a and a horizontal hole 1b, and is made of a metal hollow member formed in a substantially cross shape when viewed from the front. In the water distribution plug body 1, the vertical hole 1a, the horizontal hole 1b, a male screw portion 1c, a male screw portion 1d for saddle connection, a male screw portion 1e for water supply pipe connection, and a core insertion hole 1f are formed. The water distribution plug body 1 mainly constitutes the water stop mechanism 10 by the vertical hole 1a, the horizontal hole 1b, a ball valve 12 disposed at the central portion of the vertical hole 1a and the horizontal hole 1b, and a plug rod 13 provided at the right end portion of the horizontal hole 1b.

[0016] The vertical hole 1a is formed to penetrate vertically along the axial line of the water distribution plug body 1. The ball valve 12 is disposed at the central portion of the vertical hole 1a. A male screw portion 1c for screwing on a cap 11 is formed on the outer peripheral portion of the upper opening of the vertical hole 1a. A core 7 is mounted in the core insertion hole 1f on the lower side of the vertical hole 1a. The core insertion hole 1f is formed along the axial line on the axial side of the male screw portion 1d for saddle connection. Note that the mounting of the core 7 is optional.

[0017] Also, when drilling a drilling hole P1a for attaching the core 7 to the water distribution pipe P1 in the water distribution pipe P1, a drilling machine (not shown) is used. The drilling machine is inserted into the vertical hole 1a of the saddle-equipped water distribution plug 100 attached to the water distribution pipe P1 from the upper opening by fastening the saddle mechanism 20 shown in FIG. 1 to the water distribution pipe P1. The drilling hole P1a is drilled in the water distribution pipe P1 by the drilling machine (not shown). After the drilling hole P1a is drilled, the core 7 is mounted in the core insertion hole 1f at the lower end portion of the vertical hole 1a. A male screw portion 1d for saddle connection is formed outside the core insertion hole 1f. A female screw portion 2d for water distribution plug connection formed on the saddle 2 is screwed onto the male screw portion 1d for saddle connection.

[0018] The horizontal hole 1b is formed to penetrate in the left - right direction at the vertical center of the water - separating faucet body 1 so as to be orthogonal to the vertical hole 1a. On the outside of the left end of the horizontal hole 1b, a male screw part 1e for connecting a water supply pipe is formed. A water supply branch joint (not shown) for attaching a water supply pipe (not shown) to the water - separating faucet body 1 is screwed onto the male screw part 1e for connecting the water supply pipe. At the right end of the horizontal hole 1b, a plug rod 13 connected to the ball valve 12 is mounted.

[0019] <Saddle mechanism> The saddle mechanism 20 is a mechanism for attaching the saddle 2 and the band 3 around the water distribution pipe P1. The saddle mechanism 20 mainly consists of a saddle 2, a band 3, a bolt B1, a nut N1, an upper insulator 5, a lower insulator 6, and a flat washer 8. The saddle mechanism 20 is formed by inserting the bolt B1 through the bolt insertion hole 3c of the flange part 3b of the band 3 and through the bolt insertion hole 2c of the flange part 2b of the saddle 2, and then screwing it with the nut N1 on the tip side of the bolt B1. The saddle 2 and the band 3 are surface - coated, for example, with a powder coating mainly composed of epoxy resin.

[0020] <Saddle> As shown in FIG. 1, the saddle 2 is an upper half body arranged on the outer periphery of the water distribution pipe P1 so as to hold the upper outer peripheral part of the water distribution pipe P1. The saddle 2 is joined to the lower end of the water - separating faucet body 1. The saddle 2 has a holding part 2a, a flange part 2b, a bolt insertion hole 2c, a female screw part 2d for connecting the water - separating faucet, and a step part 2e. The saddle 2 is made of a strip - shaped metal extending in the left - right direction in a plan view, has a female screw part 2d for connecting the water - separating faucet at the central part, and has bolt insertion holes 2c at both left and right ends respectively. The saddle 2 is formed in a substantially Ω - shaped in a front view, the holding part 2a at the central part is formed in an arc shape, and the flange parts 2b at both ends are formed in a flat plate shape. Note that the step part 2e is optional.

[0021] The holding part 2a is a part that holds the water distribution pipe P1 from one side (upper side). The holding part 2a is formed in an arc shape in a front view. The flange portion 2b is a pair of left and right flat plate-like portions horizontally protruding outward from the left and right end portions of the holding portion 2a. The bolt insertion hole 2c is a hole into which the male screw portion B1c of the bolt B1 is inserted. The bolt insertion holes 2c are respectively formed in the pair of flange portions 2b. The female screw portion 2d for connecting the water stopcock is a screw hole into which the male screw portion 1d for saddle connection of the water stopcock body 1 is screwed. The female screw portion 2d for connecting the water stopcock is formed in the central portion of the holding portion 2a. The stepped portion 2e is a portion where the locking claw 5c of the upper insulator 5 is locked. The stepped portion 2e is formed within the flange portion 2b.

[0022] <Band> The band 3 is disposed opposite to the saddle 2 with the water distribution pipe P1 interposed therebetween, and is a lower half body for holding the water distribution pipe P1 together with the saddle 2. The band 3 has a holding portion 3a formed in an arc shape when viewed from the front, a pair of flange portions 3b horizontally protruding outward from the left and right end portions of the holding portion 3a, bolt insertion holes 3c respectively formed in the pair of flange portions 3b, and a stepped portion 3e formed within the flange portion 3b. The band 3 is formed in a shape that is substantially symmetric with respect to the saddle 2 when viewed from the front. The band 3 is formed in a substantially inverted Ω shape when viewed from the front, with the holding portion 3a at the center formed in an arc shape and the flange portions 3b at both ends formed in a flat plate shape. The band 3 is made of a strip-shaped metal extending in the left-right direction in a plan view, and has bolt insertion holes 3c at both left and right end portions respectively. Note that the stepped portion 3e is optional.

[0023] <Bolt> The bolts B1 are a pair of fastening members for connecting and fixing the saddle 2 and the band 3 to the outer peripheral portion of the water distribution pipe P1. The bolt B1 is a commercially available bolt having a head B1a, a cylindrical body portion B1b which is a shaft portion, and a male screw portion B1c. Note that the bolt B1 may be a so-called full-thread bolt in which the entire shaft portion is composed of the male screw portion B1c.

[0024] <Nut> The nut N1 is a fastening tool for fixing the saddle 2 to the band 3 by screwing it onto the male thread portion B1c of the bolt B1 and tightening it, with the flat washer 8 and the upper insulator 5 interposed between the nut N1 and the flange portion 2b of the saddle 2. The nut N1 is a commercially available hexagonal nut. The nut N1 is screwed onto the male thread portion B1c of the bolt B1 that passes through the upper insulator 5 fitted inside the bolt insertion hole 2c of the saddle 2 and the flat washer 8 placed on the upper insulator 5. When the nut N1 is tightened with a tightening tool such as a wrench, the nut N1 is screwed onto the bolt B1 in a state where the lower surface of the nut N1 abuts against the upper insulator 5 with the flat washer 8 interposed therebetween.

[0025] <Upper insulator> As shown in FIG. 3, the upper insulator 5 is an elastic insulator that is pushed into and mounted in the bolt insertion hole 2c and is disposed on the inner wall of the bolt insertion hole 2c and the peripheral portion of the opening edge. The upper insulator 5 has a cylindrical portion 5a, a flange portion 5b, a locking claw 5c, and a protruding portion 5d. Further, it is preferable that the upper insulator 5 has a catching portion 5e.

[0026] The cylindrical portion 5a is formed in a cylindrical shape. The cylindrical portion 5a is a cylindrical part arranged to be fitted inside the inner wall of the bolt insertion hole 2c. The flange portion 5b is formed at the upper end portion (the end portion on the nut N1 side) of the cylindrical portion 5a. The flange portion 5b is an annular plate portion extending radially outward from the opening edge at the upper end of the cylindrical portion 5a, and the flat washer 8 is placed on the flange portion 5b. The flange portion 5b has a function of preventing the flat washer 8 from directly touching the saddle 2. The locking claw 5c is formed at the lower end portion of the cylindrical portion 5a. The locking claw 5c is a locking portion for being locked to the stepped portion 2e and holding the upper insulator 5 so that it does not easily come off from the saddle 2.

[0027] As shown in FIGS. 4 to 6, the protruding portion 5d extends upward (toward the nut N1 side) from the surface on the outer peripheral side of the flange portion 5b, and restricts the radial movement of the flat washer 8 (see FIG. 3). That is, when the outer peripheral surface of the flat washer 8 abuts against the protruding portion 5d, the radial movement of the flat washer 8 is restricted. In the present embodiment, a plurality (for example, four) of protruding portions 5d are formed separately in the circumferential direction. Here, the protruding portion 5d has an arcuate surface shape, but is not limited thereto, and may have, for example, a pin (cylindrical) shape.

[0028] The catching portion 5e is formed on the tip side of the protruding portion 5d, and restricts the axial movement of the flat washer 8. That is, when the upper surface of the flat washer 8 abuts against the catching portion 5e, the axial movement of the flat washer 8 is restricted. In the present embodiment, a plurality (for example, four) of catching portions 5e are formed separately in the circumferential direction. Here, the catching portions 5e are formed on all of the plurality of protruding portions 5d respectively. Note that the catching portions 5e may be formed on only a part, rather than all, of the plurality of protruding portions 5d. Also, the catching portions 5e do not have to be formed over the entire circumferential length range on the tip side of the protruding portion 5d, and may be formed on a part of the circumferential length range on the tip side of the protruding portion 5d.

[0029] As shown in FIG. 3, the catching portion 5e has a protruding portion that protrudes radially inward from the inner surface of the protruding portion 5d, and the shape of the catching portion 5e is not particularly limited and can be changed as appropriate. In the present embodiment, in a plan view, the inscribed circle diameter of the catching portion 5e is set to be larger than the circumscribed circle diameter of the nut N1 and smaller than the outer diameter of the flat washer 8. In the present embodiment, the upper insulator 5 is a substantially cylindrical member made of resin such as integrally formed polycarbonate. Note that the upper insulator 5 is not limited to a configuration in which the whole is integrally formed. For example, the protruding portion 5d and the flange portion 5b may be formed separately and then combined.

[0030] <Lower insulator> As shown in Fig. 1, the lower insulator 6, like the upper insulator 5, is a resilient insulator that is pushed into and mounted in the bolt insertion hole 3c and is disposed on the inner wall of the bolt insertion hole 3c and the peripheral portion of the opening edge. The lower insulator 6 is a substantially cylindrical member made of resin such as polycarbonate, which is integrally formed with a cylindrical portion 6a formed in a cylindrical shape, a flange portion 6b formed at the lower end of the cylindrical portion 6a, a locking claw 6c formed at the upper end of the cylindrical portion 6a, and a guide covering portion 6d composed of protruding pieces protruding downward from the front end and the rear end of the flange portion 6b.

[0031] <Insulator guide> As shown in Fig. 2, the insulator guide 9 is a member that is mounted in the flange portion 6b and the guide covering portion 6d that are bent and formed in a reverse concave shape when viewed from the side of the lower insulator 6. The insulator guide 9 is formed of a metal plate such as a stainless steel plate. The insulator guide 9 includes a washer portion 9a having a bolt insertion hole (not shown), and bent pieces 9b protruding downward from the front end and the rear end of the washer portion 9a. The head B1a of the bolt B1 is inserted between the front and rear bent pieces 9b.

[0032] <Flat washer> The flat washer 8 is, for example, a commercially available one and has a ring plate shape. The flat washer 8 is interposed between the lower surface of the nut N1 and the flange portion 5b of the upper insulator 5. The flat washer 8 is formed of a metal plate such as a stainless steel plate.

[0033] <Core> As shown in Fig. 1, the core 7 is a substantially cylindrical member that is attached to the inside of the water distribution pipe P1 and the core insertion hole 1f at the lower end of the vertical hole 1a of the saddle-type water distribution faucet 100, and suppresses the reduction due to rust in the drilling hole P1a. The lower end portion of the core 7 is inserted into the drilling hole P1a drilled by a drilling machine (not shown) inserted into the vertical hole 1a of the saddle-type water distribution faucet 100. The upper end portion of the core 7 is mounted in the core insertion hole 1f.

[0034] [Operation of the saddle-type water distribution faucet] Next, the operation of the saddle-type water distribution faucet 100 according to the embodiment of the present invention will be described along the installation procedure.

[0035] First, as shown in FIG. 1, the upper insulator 5 is pushed into and mounted in the bolt insertion hole 2c formed in the flange portion 2b of the saddle 2. Also, the lower insulator 6 is pushed into and mounted in the bolt insertion hole 3c formed in the flange portion 3b of the band 3.

[0036] Subsequently, as shown in FIG. 3, the flat washer 8 is detachably mounted inside the protruding portion 5d of the upper insulator 5 by pushing it inward while slightly moving the engaging portion 5e radially outward. As a result, the flat washer 8 is locked in a state of being placed on the flange portion 5b of the upper insulator 5. However, first, the flat washer 8 may be mounted on the upper insulator 5, and then, the upper insulator 5 with the flat washer 8 mounted thereon may be mounted in the bolt insertion hole 2c of the flange portion 2b of the saddle 2.

[0037] Next, as shown in FIG. 1, the male threaded portion B1c of the bolt B1 is inserted from below into the bolt insertion hole 3c of the band 3 on which the lower insulator 6 is mounted. Subsequently, the male threaded portion B1c protruding upward is inserted from below into the bolt insertion hole 2c of the saddle 2 on which the upper insulator 5 is mounted. Subsequently, a nut N1 is fitted onto the male threaded portion B1c and tightened with a tightening tool such as a wrench. As a result, the saddle-type water faucet 100 is fixed to the water distribution pipe P1.

[0038] When tightening the nut N1, usually only the flat washer 8 rotates on the flange portion 5b of the upper insulator 5 as the nut N1 rotates, and the upper insulator 5 hardly rotates. Also, the flange portion 5b of the upper insulator 5 is interposed between the flat washer 8 and the flange portion 2b of the saddle 2. Therefore, the upper insulator 5 can prevent the occurrence of corrosion due to peeling of the paint on the saddle 2 by the flat washer 8 when tightening the nut N1. Also, the upper insulator 5 also functions to prevent loosening of the nut N1 and equalize the tightening load.

[0039] In the above-described embodiment, the bolt B1 is inserted through the bolt insertion hole 3c of the band 3 to which the lower insulator 6 is attached, the bolt insertion hole 2c of the saddle 2 to which the upper insulator 5 is attached, and the flat washer 8 in this order and is screwed with the nut N1. The upper insulator 5 has a cylindrical portion 5a, a flange portion 5b, and a protruding portion 5d. The cylindrical portion 5a is formed in a cylindrical shape. The flange portion 5b is formed at the upper end of the cylindrical portion 5a, and the flat washer 8 is placed thereon. The protruding portion 5d extends upward from the surface on the outer peripheral side of the flange portion 5b and restricts the radial movement of the flat washer 8.

[0040] According to such an embodiment, during the operation of attaching the saddle-type water faucet 100 to the water distribution pipe P1, the flat washer 8 is placed on the flange portion 5b of the upper insulator 5 and is positioned with its radial movement restricted by the protruding portion 5d. Therefore, this embodiment can provide the saddle-type water faucet 100 that can suppress the dropping of the flat washer 8 used when attaching the saddle-type water faucet 100 to the water distribution pipe P1. Thereby, in the installation work in a narrow and dark place where the road surface or the like is excavated, it is possible to avoid a situation where the flat washer 8 drops, the flat washer 8 is lost, or mud, sand, etc. adhere to the flat washer 8, resulting in a reduction in workability.

[0041] Further, in this embodiment, the upper insulator 5 has a catching portion 5e formed on the tip side of the protruding portion 5d to restrict the axial movement of the flat washer 8. In this configuration, the flat washer 8 is placed on the flange portion 5b of the upper insulator 5, and while its radial movement is restricted by the protruding portion 5d, its axial movement is restricted by the catching portion 5e and it is positioned. Therefore, it is possible to provide the saddle-type water faucet 100 that can further suppress the dropping of the flat washer 8. At the time of shipment of the saddle-type water faucet 100, the upper insulator 5 is attached to the saddle 2. In this case, the flat washer 8 may be attached to the upper insulator 5 from the time of shipment of the saddle-type water faucet 100. In this way, it is possible to effectively prevent the omission of attaching the flat washer 8. Note that the flat washer 8 may be attached to the upper insulator 5 when installing the saddle-type water faucet 100.

[0042] Note that the upper insulator 5 may be configured not to have the engaging portion 5e. Even in this case, since the movement of the flat washer 8 in the radial direction is restricted by the protruding portion 5d, the effect of suppressing the fall of the flat washer 8 can be obtained. In this case, it is preferable that the flat washer 8 is attached to the flange portion 5b of the upper insulator 5 by an adhesive member. As the adhesive member, for example, an adhesive or a double-sided tape can be used. In this way, the fall of the flat washer 8 can be further suppressed. Here, since the adhesive force of the adhesive member is relatively weak, the flat washer 8 is attached to the flange portion 5b by the adhesive member before tightening the nut N1, but rotates as the nut N1 rotates when tightening the nut N1.

[0043] Also, in the present embodiment, a plurality of protruding portions 5d are formed separately in the circumferential direction. With this configuration, the movement of the flat washer 8 in the radial direction can be efficiently restricted with less material. The flat washer 8 can also be easily mounted into the protruding portion 5d. Also, when the engaging portion 5e is provided, the flat washer 8 can be pushed in while slightly moving the engaging portion 5e radially outward with a relatively small force.

[0044] Also, in the present embodiment, a plurality of engaging portions 5e are formed separately in the circumferential direction. With this configuration, the flat washer 8 can be more reliably restricted from moving in the axial direction at a plurality of locations in the circumferential direction by the plurality of engaging portions 5e. However, the engaging portion 5e may be provided at one location in the circumferential direction. Even in this case, the movement of the flat washer 8 can be restricted and positioned by the cooperation of the protruding portion 5d and the engaging portion 5e.

[0045] Further, in the present embodiment, the inscribed circle diameter of the engaging portion 5e is larger than the circumscribed circle diameter of the nut N1. In this configuration, since the engaging portion 5e and the nut N1 do not interfere with each other, the nut N1 can be easily tightened using a tightening tool such as a wrench, and the same construction as in the prior art is possible. However, the inscribed circle diameter of the engaging portion 5e may be equal to or slightly smaller than the circumscribed circle diameter of the nut N1. In this case, when the nut N1 is tightened, the nut N1 rotates and contacts the engaging portion 5e, but the engaging portion 5e moves slightly radially outward.

[0046] FIG. 7 is an enlarged perspective view of the upper insulator 51 according to the first modification. FIG. 8 is an enlarged plan view of the upper insulator 51 according to the first modification. FIG. 9 is a cross-sectional view taken along line A-A of FIG. 8. As shown in FIGS. 7 to 9, in the upper insulator 51 according to the first modification, the protruding portion 5d1 is formed as one continuous piece in the circumferential direction, and the engaging portion 5e1 is formed on the tip side of the protruding portion 5d1. Otherwise, the upper insulator 51 is the same as the upper insulator 5 described above. The protruding portion 5d1 is formed in a range exceeding 180 degrees along the circumferential direction in order to restrict the radial movement of the flat washer 8. With this configuration, the flat washer 8 can be positioned more reliably. In FIGS. 7 to 9, the protruding portion 5d1 is formed in a range less than 360 degrees along the circumferential direction, but it may be formed along the entire circumference in the circumferential direction.

[0047] FIG. 10 is an enlarged cross-sectional view of the upper insulator 52 according to the second modification. As shown in FIG. 10, in the upper insulator 52 according to the second modification, the protruding portion 5d2 extends upward from the surface on the inner peripheral side of the flange portion 5b and restricts the radial movement of the flat washer 8 (see FIG. 3). That is, when the inner peripheral surface of the flat washer 8 abuts against the protruding portion 5d2, the radial movement of the flat washer 8 is restricted. Further, the engaging portion 5e2 is formed on the tip side of the protruding portion 5d2. Otherwise, the upper insulator 52 is the same as the upper insulator 5 described above. With this configuration as well, the same effects as those of the above-described embodiment can be obtained.

[0048] As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the configurations described in the above embodiments and modifications. The present invention can appropriately change its configuration without departing from the gist thereof, including appropriately combining or selecting the configurations described in the above embodiments and modifications. Further, additions, deletions, and substitutions can be made to a part of the configurations of the above embodiments and modifications.

[0049] For example, in the above-described embodiment, the surface of the flange portion 2b of the saddle 2 is horizontal, but the present invention is not limited thereto. The present invention is also applicable to a saddle-type water faucet in which the surface of the flange portion of the saddle is inclined with respect to the horizontal plane. Such a saddle-type water faucet is particularly likely to have the flat washer fall off, and thus it is desirable to apply the present invention.
