本考案は釣竿、ゴルフシヤフト等の管状体の強
度を向上することを目的とするものである。[Detailed description of the invention] Purpose of the invention The purpose of the invention is to improve the strength of tubular bodies such as fishing rods and golf shafts.

公昭58−49105号公報で知られている。Prior Art A fishing rod in which reinforcing fiber strips impregnated with synthetic resin are wound around the outer peripheral surface of a tapered tubular body made of high-strength fiber impregnated with synthetic resin is disclosed in Japanese Utility Model Publication No. 58-49105. It is known for.

ピツチより大きくするように捲着されているた
め、小径部に至る程補強繊維条による補強効果が
減少し管状体の強度を各部均等に発揮できないの
が現状である。 However, in this case, the reinforcing fiber strips are wound so that the same pitch is larger in the small diameter part of the tubular body than in the large diameter part, so the reinforcing effect of the reinforcing fiber strips decreases as the diameter reaches the small diameter part. However, the current situation is that the strength of the tubular body cannot be exerted equally in each part.
即ち釣竿は大径部より小径部がつぶし強度は大
きいが、竿先に行く程撓み量が大きくなるためこ
れに対応するための補強が必要である。 In other words, the crushing strength of the small diameter part of a fishing rod is greater than that of the large diameter part, but the amount of deflection increases toward the tip of the rod, so reinforcement is required to cope with this.
ところが、前記公知のものは、このような撓み
に体する補強が考慮されておらず、従つて補強効
果が先端に行く程急激に減少する欠陥がある。 However, the above-mentioned known method does not take into account reinforcement for such flexure, and therefore has the defect that the reinforcing effect decreases rapidly toward the tip.

要旨とするものである。Structure of the invention The present invention is intended to improve such defects, and consists of a reinforcing fiber strip impregnated with a synthetic resin that is integrally twisted around the outer circumferential surface of a tubular body made of high-strength fiber impregnated with a synthetic resin. In the tubular body wound around the tubular body, the pitch of the reinforcing fiber strips is formed to be smaller in the small diameter part of the tubular body than in the large diameter part.

きくなるに従いP1，P2と大きくなるように捲着
されている。 An embodiment of the present invention will be explained with reference to the drawings.A fishing rod 2 formed by joining together rods 1, 1', 1'', etc. is formed by impregnating thermosetting synthetic resin into high-strength fibers such as carbon fibers and glass fibers. , its outer peripheral surface is made of carbon fiber, glass fiber, etc. impregnated with thermosetting synthetic resin.
Aramid fibers and other reinforcing fiber strips 3 are integrally wound around the twisted strips, and in particular, the pitch is the smallest at the most advanced pole 1, P, and sequentially becomes P1, P1, and P1 as the diameter increases as the poles 1' and 1'' increase in diameter. It is wrapped so that it becomes larger than P 2 .

なるように捲着すれば良い。 In the above embodiment, the reinforcing fiber strips 3 are formed at the same pitch for the same rods, and the rods with smaller pitches toward the tip end are joined together, but each rod 1,
The pitch of 1', 1'' itself may be wound so that it gradually becomes smaller from the large diameter part to the small diameter part, and in the case of a single tapered fishing rod instead of a jointed rod, the pitch of the large diameter part It is sufficient to wrap the wire so that the pitch gradually decreases from the top to the top.
また補強繊維条３は単一条だけでなく第２図の

いその本数、径、巾を減少させることもできる。 Further, the reinforcing fiber strip 3 can be not only a single thread but also a plurality of threads, such as two parallel threads at a predetermined interval as shown in FIG. You can also do it.

剥離し、管状体の成形と同時に形成する。 The means for integrally winding the reinforcing fiber strip 3 around the rod is usually to wrap a core of Pupreg impregnated with a thermosetting synthetic resin and then winding the reinforcing fiber strip impregnated with a thermosetting synthetic resin. The outer periphery is taped and heat-cured in the usual manner, and then the tape is peeled off to form the tubular body at the same time.

特徴と実用性を有するものである。Effects of the invention The present invention is particularly useful when winding reinforcing fiber strips in a twisted manner around the outer peripheral surface of a tubular body made of high-strength fibers impregnated with synthetic resin. Since the reinforcing fibers are formed to be larger, the reinforcing effect of the reinforcing fibers is proportional to the amount of deflection according to the diameter of the tubular body, and the crushing strength that can counter the amount of deflection can be improved, and the reinforcing effect of each part of the tubular body is It has excellent features and practicality that can strengthen tubular objects such as fishing rods by making it uniform.
