【産業上の利用分野】本考案は、硬質補強螺旋可撓管の
改良に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a hard reinforced spiral flexible tube.
【0002】[0002]
【従来の技術】耐摩耗性を要求する可撓管を製作するに
当って、耐摩耗性が優れているものとしては、ゴム系材
料が知られており、このゴム系材料で胴部を造る方法は
以前から行われているが、重く、不透明な欠点がある。2. Description of the Related Art In manufacturing a flexible tube requiring abrasion resistance, a rubber material is known as having excellent abrasion resistance, and a trunk portion is made of the rubber material. Although the method has been used for some time, it has heavy and opaque disadvantages.
【0003】耐摩耗性を良くするため可撓管の胴部に熱

いる。しかしながらこの素材と大きい剛性を有する補強
螺旋部との接着が悪く、実用上満足なものが得られず、
従って補強螺旋部を該素材による包み込み等により接着
力の不足を補っていた。It has long been known to use a thermoplastic urethane resin for the body of a flexible tube in order to improve abrasion resistance. However, the adhesion between this material and the reinforcing helical portion having high rigidity is poor, and a practically satisfactory one cannot be obtained.
Therefore, the deficiency of the adhesive force is compensated for by wrapping the reinforcing spiral portion with the material.
【0004】しかし、この方法では重量が増し、構造上
制約を受け、又、包み込み部に損傷を受けると、螺旋管
が破壊する恐れがある。[0004] However, in this method, the weight increases, the structure is restricted, and if the wrapping portion is damaged, the helical tube may be broken.

【考案が解決しようとする課題】本考案の課題は、前記
従来の欠点を除去し、耐摩耗性に優れ、軽量で安価にで
きる硬質補強螺旋可撓管を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a hard reinforced helical flexible tube which is excellent in abrasion resistance, lightweight and inexpensive, eliminating the above-mentioned conventional disadvantages.
