Description

  The present invention relates to an insulating member for a water faucet with a saddle used for opening a water supply pipe branched from a water main.

  A general water faucet with a saddle is fixed to the outer periphery of the main pipe with a water faucet equipped with a valve mechanism that opens and closes the flow path that connects the water pipe to the water supply pipe. A saddle, a band arranged opposite to the main water pipe and fixed to the outer periphery of the main pipe, and bolts and nuts connecting the saddle and the band are tightened via an insulating member. It is set as the structure fixed to this main pipe.

  As the material for the saddle and the band, cast iron material is usually used, and stainless steel material is used for bolts and nuts. By the way, since the saddle, the band, and the bolt and nut are different metals, a potential difference is generated by the contact between them and a current is generated, which may cause corrosion. Therefore, the saddle and band of the water faucet with a saddle are fixed with bolts and nuts after making them non-contact with an insulating member using an insulating member.

  As an example of a conventional insulating member, there is a configuration in which a cylindrical portion and a flange that are inserted into mounting holes of a saddle and a band are integrally formed, and a plurality of protrusions are provided on the outer surface of the cylindrical portion. This type of insulating member is configured to be fixed by being pressed into an inner surface of the mounting hole by being pushed into a mounting hole of a saddle or a band. In addition, there is an insulating member in a form in which a plurality of slits are provided in the cylindrical portion from the opening edge toward the inside (flange side). The insulating member is configured to be fixed by being pressed against the inner surface of the mounting hole by an elastic action when the cylindrical portion is pressed into the mounting hole of the saddle or the band to be inwardly contracted.

  By the way, although the saddle and the band are coated for rust prevention, the thickness of the coating film is not uniform and varies, so the size of the mounting hole is slightly different for each product. For this reason, when the insulating member is attached to the mounting hole, the fitting state becomes too tight, which may cause trouble when the bolt is inserted. It is in a situation where it is easy to leave. In particular, if the insulation member is easily removed from the saddle or band, it may be overlooked when the packaging is unpacked at the transportation destination, and it takes extra effort when installing the water faucet with saddle on site. There were inconveniences and inconveniences such as not getting back.

  In Patent Document 1, an insulating member (insulator) provided with an engaging claw is attached to a tapered hole of a saddle, the insulating member is attached to a stepped hole of a band, and a bolt is inserted into the insulating member. A configuration for screwing a nut is disclosed. Further, in Patent Document 2, an insulating member (insulator) provided with an engaging claw is attached to a stepped hole of a saddle and a band, a bolt is inserted into the insulating member, a nut is screwed, and a saddle is attached. A configuration in which a faucet is fixed to a main pipe is disclosed.

  Regarding the insulating member disclosed in the above document, it is assumed that the engagement state of the engaging claw may become tight or loose due to the variation in the size of the mounting hole, and the above-mentioned disadvantages are denied. Absent. Further, since the type (material, thickness) of the water main is not uniform, the form and the thickness dimension of the attachment portion are not uniform for the saddle and the band. For this reason, even if the insulating member is used for a mounting hole having the same inner diameter, a saddle or a band having a different thickness at the mounting hole is applied with only one type of insulating member. There was also the inconvenience that they could not.

  The best mode of the present invention will be described below with reference to the drawings.

  Saddle-equipped faucets are used to draw water from the water main to homes. In general, a water faucet with a saddle is a water faucet equipped with a valve mechanism that opens and closes a flow path that communicates with a water supply pipe from a water passage hole formed by a punch in a cast iron or synthetic resin water main pipe (Fig. (Not shown) attached to the outer periphery of the main pipe, a band disposed opposite the water main pipe and fixed to the outer circumference of the main pipe, and the saddle and the band are connected to each other. The bolts and nuts are fastened to the main pipe by tightening each through an insulating member.

  The water faucet is not described in detail because it is not the gist of the present invention, but has the same structure as that of a known structure.

  As shown in FIG. 4 (part on the right), the saddle 50 has a known structure (not shown) at the center of an arc portion 50a formed along the outer diameter of a predetermined size of the water main. A circular pedestal 50b is provided for attaching the water faucet in the vertical direction. A part (not shown) of the water faucet is screwed and fixed to the screw hole 51 (inner diameter: 40 mm) formed in the base 50b. A flange 50d having a thickness of 13 mm extending in the horizontal direction is integrally formed on both sides from the edge portion 50c of the arc portion 50a. Each of the flanges 50d is provided with a mounting hole 52 (inner diameter: 21 mm).

  As shown in part of FIG. 5, the band 55 is similar to the saddle 50 on both sides from the edge portion 55 b of the arc portion 55 a formed along the outer diameter of a predetermined size of the water main. In addition, a flange 55c having a thickness of 13 mm extending in the horizontal direction is integrally formed. Each of the flanges 55c is provided with a mounting hole 56 (inner diameter: 21 mm). These mounting holes 56 are arranged so as to correspond to the mounting holes 52 of the saddle 50. 55d is a pair of blocks (projections) provided on the back side of the flange 55c so as to face the periphery of the mounting hole 56. These blocks 55d are provided to prevent rotation of bolts 61 described later.

  The saddle-side insulating member 1 includes a synthetic resin insulating main body 10 and a synthetic resin stopper ring 30. As shown in FIG. 1, the insulating main body 10 is integrally formed with a cylindrical portion 11 (inner diameter: 11 mm, thickness 1.5 mm) having a plurality of circumferential grooves 12 on the outer surface 11 a and a flange 13.

  In this embodiment, since the cylindrical portion 11 is provided with a plurality of circumferential grooves 12, the thickness of the flange 50d of the saddle 50 is different, or the coating thickness at the 52 mounting holes varies. In some cases, one type of insulating member can be used.

  The band-side insulating member 1 ′ is composed of an insulating main body 20 made of synthetic resin and a stopper ring 30 made of synthetic resin.

  It is preferable that the insulating main body 20 shown in FIG. 2 is adopted as the insulating member 1 ′ (the invention of claim 2), but the insulating main body 10 can be applied without being limited thereto. (Invention of Claim 1).

  That is, a pair of rising pieces 24 and 24 are integrally formed on the outer edge of the flange 23 of the insulating main body 20 so as to face each other at a predetermined interval. A protrusion (or protrusion) 25 having a height of about 0.5 mm is integrally formed on the inner surface 24 a of the rising piece 24 in a direction parallel to the upper surface of the flange 23, and a bolt 61 described later is inserted by the protrusion 25. The stainless steel (metal) washer 63 is provided so as to prevent the loss. Reference numeral 22 denotes a plurality of circumferential grooves provided in the cylindrical portion 21.

  In addition, the said washer 63 uses the thing of the form by which a pair of upward piece 63b was integrally formed in the outer edge of the ring part 63a.

  Then, as shown in FIG. 7, the side surface 62a of the head 62 of the bolt 61 described later is arranged inside the rising piece 24 of the insulating main body 20, more specifically, inside the upward piece 63b of the washer 63. The rotation of the bolt 61 is prevented, and the rising pieces 24 and 24 come into contact with a block 55d provided on the band 55 to prevent the bolt 61 from rotating.

  As shown in FIG. 3, the stopper ring 30 is elastically deformed into the circumferential groove 12 of the insulating body 10 or the circumferential groove 22 of the insulating body 20 inward of the tip edge of the cylindrical portion 31 having the flange 32. Thus, the three claw pieces 33 that can be engaged are formed at equal angular intervals.

  Then, the insulating main body 10 is loosely fitted in the mounting hole 52 of the saddle 50 and the insulating main body 20 is loosely fitted in the mounting hole 56 of the band 55, and the respective stopper rings 30 are attached to the insulating main body 10 and the insulating main body 20. By pushing in from the opposite side, each claw piece 33 of the ring 30 engages with the circumferential groove 12 and the circumferential groove 22, respectively, so that the insulating members 1 and 1 'of the saddle-equipped water faucet are integrated.

FIG. 6 shows another embodiment of the insulating body. The insulating main body 40 is provided with an engagement hole 42 instead of the peripheral groove 12 of the insulating main body 10 and the peripheral groove 22 of the insulating main body 20. The configuration other than the engagement hole 42 is the same as that of the insulating main body 10.
That is, the insulating main body 40 is provided with three engagement holes 42 at equiangular intervals around a cylindrical portion 41 provided with a flange 42. Then, the claw pieces 33 of the stopper ring 30 are engaged with the engaging holes 42 so that the stopper ring 30 is mounted on the insulating main body 40.

  When the thickness of the flange 50d of the saddle 50 is different, a plurality of engagement holes 42 provided in the insulating main body 40 can be provided in the axial direction.

  As described above, FIG. 7 shows a state where the saddle 50 to which the insulating member 1 is attached and the band 55 to which the insulating member 1 ′ is attached are connected by the bolt 61 and the nut 65.

  As described above, the insulating member of the water faucet with a saddle according to the present invention has the stopper ring 30 from the opposite side to the insulating main bodies 10 and 20 that are loosely fitted into the mounting holes 52 and 56 of the saddle 50 and the band 55, respectively. By respectively pushing in, it can mount | wear with respect to the saddle 50 and the band 55 reliably. This eliminates the inconvenience such as the insulation member coming off during transportation. In addition, since the insulating member is not likely to fall out of the saddle 50 or the band 55 when performing the installation work of the water faucet with saddle, the work is easy to perform.
