As shown in FIG. 8, a pull type in which a guide coil 31 is covered with a synthetic resin outer tube 51 and an inner wire 61 made of a metal stranded wire is inserted into the guide coil 31 as shown in FIG. B (pull type), and further, as shown in FIG. 9, a polyethylene liner 71 is covered with a polyethylene outer tube 51 via a stranded-type shielding material 41, and a metal liner having a core in the liner 71. Person C formed by inserting the inner wire 81 consisting of a stranded wire (pull
Push type). Person A inserts both ends of the guide coil 31 and the shield member 41 into the joint fittings 2 and 3, and fixes the joint fittings 2 and 3 to the guide coil 31 by integrating them. 3, the outer tube 51 is layered and connected to joint fittings 2 and 3 with an operating part (not shown) and an operating part (not shown). ), A middle caulking fitting 1 "to be lightly caulked and fixed to the end of the main body 1 in the joint fittings 2 and 3 of the operation unit (not shown), and the middle caulking fitting 1".
Are connected to the joint fittings 2 and 3 by caulking and fixing, and the end of the main body 1 is inserted into the joint fittings 2 and 3 of the operation section (not shown) and the operation section (not shown). Then, the joint fittings 2 and 3 are lightly swaged and fixed to the end of the main body 1 and connected. As shown in FIG. 10, such a release for the preceding drain plug device includes an operating part A provided on a bathtub, an upper edge surface of a counter or a wash basin, and an operating part provided on a drain port as shown in FIG. (Open / close clutch mechanism) B
And connected to.

[0003]

However, since the prior art has a structure in which the main body 1 of the release is integrated with the joint fittings 2 and 3, the operation section A and the
When connecting to the operating portion B provided at the drain port, an assembling work of inserting a nut 600 and the like for attachment to the main body 1 is required as a pre-connection stage, and of course the cost increases due to an increase in the number of parts. In addition, there was a problem that connection was impossible at the construction site due to forgetting to assemble. Person A has a structure in which the cutting stress concentrates on the crimped and fixed portion of the guide coil 31 because the joint fittings 2 and 3 are crimped and fixed to the guide coil 31. For example, as shown in FIG. 11, when the guide tube 9 is gripped and transported while being attached to the bathtub C together with the drainage plug device, when the tensile stress is generated in the main body 1 of the release, the guide coil 31 may be easily cut. There was. Further, in the case of the type which is lightly crimped and fixed as in Nos. B and C, no cutting stress is generated, but there is a problem that the main body 1 is easily detached from the joint fittings 2 and 3 by a light pulling force. Also, in the state of being attached to the bathtub C,
A drainage cylinder 8 having an operating portion B and a support member 38 having an open lower surface
And one end of a soft synthetic resin guide tube 9 connected to the upper edge surface c1 of the bathtub C with the support member 38 of the bathtub with the tube clip 700 to hold the guide tube 9 and the support member 38 together. The main body 1 is inserted and connected over an operating portion A provided on the upper edge surface c1 of the bathtub C and an operating portion B in the drainage tube 8, and the curved portion 1 on the operating portion B side of the main body 1 is connected.
“a” has a form that protrudes downward from the open portion of the support member 38 in an arc shape. However, when the guide tube 9 is deformed due to erroneous grasping during the transfer of the bathtub, or when the guide tube 9 is detached from the support member 38 and a pulling force is applied to the main body 1, the root portion 1a of the main body 1 connected to the operating portion B 'May buckle. Further, what is required of such a release for a drainage plug device is excellent bending properties and good sliding properties at the time of bending. In recent years, bathrooms and washrooms have, for example, water heaters and local washing devices called washlets,
Various equipment such as shower water spouts for hair washing are built in, and the necessary water supply and hot water supply pipes, as well as electrical wiring etc. are arranged in a complicated state, so the release In order to avoid these pipes and wires, it is necessary to provide a curved arrangement of about 10 mm. In addition, when the person bends suddenly, the drain plug should be lightly operated (3 kg or less) by elderly people, children, as well as people with disabilities. To be able to open and close, today's diversifying bathrooms based on welfare measures,
This is a development that has been eagerly sought when installing drain cocks in washrooms. Conventionally, the push-type release of the prior art A described above is such that the shield material 41 prevents the resin from entering the wire gap of the guide coil 31 when the outer tube 51 is baked.
Guide coil 31
The guide coil 31 prevents the core coil 1 'from extending due to the sliding resistance so that the sliding stroke of the core coil 1' does not vary, and the core coil 1 ' It is considered appropriate in that it does not buckle due to the pressing force like a rod or a rod. But,
The friction between the metal of the core coil 1 'and the guide coil 31 cannot be avoided, the slidability is not smoothed to the desired extent, and the operating force is increased due to the influence of the metal fine powder. 31, shield material 41, outer tube
It was a reality that the desired degree of flexibility could not be obtained due to the increase in strength due to the polymerization of 51.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned various circumstances, and an object thereof is to cover an operating portion and an operating portion without assembling connecting members such as mounting nuts one by one. Release for drainage plug device with excellent durability that does not come off or cut out, and that exhibits smooth slidability by light operation permanently even when it is installed in a curved position of about 10 mm. Is to provide.

[0005]

According to a first aspect of the present invention, there is provided a technical means in which a pushing force from an operating section is applied to a flexible outer tube formed of a fluororesin material. A main body is formed by slidably inserting a coil-shaped core coil made of a metal material to be transmitted to the operating portion, and flanges provided around both ends of the outer tube are inserted into the operating portion and the operating portion through a release fitting. A rotation guide ring material that is accommodated in the accommodation recess formed around the hole and that is loosely fitted to the outer tube is interposed between the flange portion and the outer peripheral surface of the outer tube in the accommodation recess, and the joint fitting is rotationally guided. The gist is that it is fixed to the ring material for use. The second aspect of the present invention is more effective when the end portion of the ring member for rotation guide according to the first aspect has a sharp shape in contact with or close to the flange of the outer tube. According to a third aspect of the present invention, there is provided a spring which has one end engaged with the rotation guide ring member on the operation portion side and which comes into contact with a desired range of the outer tube and is wound. Incidentally, tetrafluoroethylene resin is preferable as the fluorine-based resin material.

[0006]

According to the above technical means, the following effects are obtained. (Claim 1) A rotation guide for inserting a flange at the distal end of an outer tube into the joint fittings for both the operating portion and the operating portion and loosely fitting on the outer peripheral surface of the outer tube to abut or approach the flange. Since the ring member is fixed to the joint fitting, both joint fittings can rotate independently of the outer tube while the outer tube is connected. In addition, excellent flexibility equivalent to the core coil of a flexible outer tube made of fluororesin material, flexibility in bending arrangement without restoring reaction force, difficult ductility and sharp bending arrangement and sliding stroke The fineness of the outer tube, which is reduced by the sliding resistance of the core coil little by little due to the self-lubricating property and the continuation of opening and closing, becomes lubricant when sliding, and when sliding like metal fine powder or resin fine powder. It does not create a factor that lowers the smoothness of the tire, and exhibits good sliding properties with stable and light force permanently. Further, the tip of the rotation guide ring member abuts against the flange to prevent the outer tube from coming off. (Claim 2) The joint fitting can be smoothly rotated with a small resistance due to the line contact of the sharp portion at the tip of the rotation guide ring material with the flange portion of the outer tube, and the sharp portion is the same flange portion in the pulling direction. This increases the strength of the outer tube coming out of the outer tube, and prevents water from entering the outer tube by the line contact. (Claim 3) When a spring that locks one end to the rotation guide ring member on the operating portion side and winds it around a desired area of the outer tube has a space (gap) with respect to the outer tube, a pulling force or pushing up is performed. When force acts, buckling is tolerated by the presence of the space (gap). However, since the spring is in contact with the outer tube, the buckling stress absorbs the elasticity of the spring well, thereby reliably preventing the outer tube from buckling.

[0007]

As described above, the present invention has the following advantages. (Claim 1) Since the joint fittings for the operating portion and the operating portion are rotatably provided at both ends of the outer tube, connection is made when connecting the operating portion and the opening / closing clutch mechanism provided at the drain port. It is not necessary to perform an assembling operation of inserting a nut for attachment as a pre-stage, and there is no possibility that connection will not be possible at the construction site due to forgetting to assemble or the cost will rise. In addition, since the tip of the rotation guide ring material abuts against the flange while being rotatable to prevent the outer tube from coming off from the joint fitting, the outer tube can be connected to the operating section, operating section, etc. Even if a pulling force acts on the tube, the release structure having the joint fittings at both ends is maintained, and the tube does not come off. In addition, as a result of the outer tube being made of a flexible material made of a fluororesin material, it has excellent flexibility equivalent to that of the core coil, adaptability at the time of curved arrangement without restoring reaction force, and rapid ductility. It is possible to provide a smooth curved arrangement and a constant sliding stroke.Also, the powder of the outer tube, which is cut off by the self-lubricating function and the sliding resistance of the core coil, becomes a lubricant during sliding and can be used with a light force. Since it was found that smooth slidability was exhibited permanently, water supply, hot water supply pipes, etc., which were intricate by incorporating various facilities such as a water heater, a local washing device called a washlet, a shower water spout for hair washing, etc. Even if it is curved with a curvature of about 10 mm while skillfully avoiding obstacles under the arrangement of electric wiring, not only elderly people and children but also disabled people can perform a predetermined sliding stroke with a light (3 kg or less) operating force. It is possible to provide a release for the drain plug device that excels in durability to slide all the time I. (Claim 2) Further, at the time of connection to the operating portion and the operation portion, the rotation guide ring member rotates while being in line contact with the flange portion of the outer tube at the sharp portion at the tip thereof, so that the connection work is also easy. Not only that, the sharp portion cuts into the flange in the pulling direction to support the outer tube so that the outer tube does not come off. Since there is no danger of coming off from the tube, and because the line contact prevents water from entering the outer tube,
Rust and the like that increase sliding resistance and deteriorate operability are not generated in the core coil. Therefore, a drain plug device which is excellently durable in that it is always slid with a predetermined sliding stroke with a light (3 kg or less) operating force while being curved with a curvature of about 10 mm and is not hindered by external conditions. Was able to provide a release. (Claim 3) In addition, a spring is provided which locks one end of the rotation guide ring member on the operation section side and abuts on a desired range of the outer tube and winds it, thereby maintaining the curved shape of the main body near the operation section. As a result, even if the guide tube is deformed due to erroneous grasping during transport of the bathtub or it comes off and a pulling force is generated on the main body, it is bent against the pulling force by the shape retaining elasticity of the spring Since the shape is maintained, there is no danger that the base portion of the main body connected to the operating portion will buckle, and it is possible to provide a drainage device suitable as a release for a drainage plug device which is transported in a state of being mounted in a bathtub in advance.
