Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a release wire. More specifically, it remotely controls various devices (such as a release device for a camera and a device for opening and closing a lid of a drainage tap) so that an operation unit and an operation unit that responds to the operation of the operation unit are linked. Regarding release wire incorporated into the mechanism.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 3, a core coil 10 formed in a coil shape by a wire material such as a steel wire and a core coil 10 formed in a coil shape by a flat wire material such as a flat steel wire slides inside the core coil 10. A release wire W'composed of a guide coil 20 inserted as much as possible and an outer tube 30 having a synthetic resin material such as vinyl coated on the outside of the guide coil 20 by baking or the like is known.

The release wire W ′ can be curvedly arranged by the flexibility of the core coil 10 and the guide coil 20 and the flexibility of the outer tube 30. For example, as shown in FIG. 2, a bathtub, a washbasin, etc. Is installed between the operation part a having the drain plug structure provided on the bottom wall a of the tank part and the operation part b having the push button structure provided on the upper edge rim surface b of the tank part. The operation of the operation part b is transmitted to the operation part a by applying a pressing force to the core coil by operating the part b and sliding the core coil in the guide coil.

[0004]

[Problems to be solved by the device]

 However, according to the above conventional release wire W ', since the core coil 10 and the guide coil 20 covering the core coil 10 are both made of metal, when the core coil 10 slides, the core coil 10 and the guide coil 20 are bent at the curved portion. There was a problem that 20 rubbing sounds were generated, and there was a risk that the core coil 10 would cause sliding failure due to rust.

Further, since a coil-shaped member, which is time-consuming to manufacture, is used for the core portion (core coil 10) and the guide portion (guide coil 20), there is a drawback that the product cost becomes high.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a release which can function as a normal sliding operation for a long time and can be manufactured at low cost. To provide the wire.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the release wire according to the present invention is a release wire that links an operation part and an operation part that responds to the operation of the operation part. In claim 1, a cylinder made of a desired resin material is used. It is characterized in that a filament core is slidably inserted in an outer tube formed in a shape of a line.

The filament core is formed of a desired metal material such as stainless steel into a coil shape or a rod shape, and the outer tube is formed of a desired resin material, preferably tetrafluoride. It is assumed that it is formed of ethylene resin into a tubular shape. Further, in claim 2, the filament core is a resin rod made of a desired resin material such as ethylene tetrafluoride resin.

[0009]

[Action]

 According to the above-mentioned means, the metal wire core is slidably inserted into the resin outer tube, so that it is possible to prevent the generation of rubbing noise when the wire core slides, and to prevent the wire from being rusted due to rust. The sliding failure of the core can be prevented. At the same time, the cost of the product will be reduced by using only the core part as the coil-shaped member, which is time-consuming to manufacture, and simplifying the wire body, which has been a three-layer structure in the past, into a double-layer structure.

When the linear core is a resin rod, the core portion (linear core) and the guide portion (outer tube) that covers the core are both made of resin, and the curved portion of the wire main body Prevents wear of the outer tube at the rubbing area between the strip core and the outer tube.

【Example】

 An embodiment of the release wire according to the present invention will be described below with reference to FIGS. In this embodiment, as shown in FIG. 2, a release wire W is shown which is incorporated in a device for opening and closing a drainage tap such as a bathtub and a washbasin, and the release wire W is provided on the operating part b side of the opening and closing device. The half portion Wa and the half portion Wb on the side of the operating portion a are connected by connecting metal pieces c1 and c2 described later.

The operating portion a of the stopper lid opening and closing device is provided on the bottom wall a of the tank portion such as a bathtub and washbasin. The stopper lid a1 opens and closes the drain outlet, and the support shaft a2 supports the stopper lid a1. Thrust lock mechanism a3 Ac, which is a combination structure of serrated grooves and protrusions and vertically moves the support shaft a2 alternately and continuously, the support shaft a2 and the thrust lock mechanism a3 are housed in a box a4 fixed to the bottom wall a4. ,,.
