Description

The present invention relates to a fishing rod, and more

  particularly to a fishing rod which is made of a reinforcement of a high strength fiber impregnated with synthetic resin and molded to be hollow and cylindrical. A conventional fishing rod, as is well known, has a body made of a pre-impregnated sheet which is mainly formed of parallel threads of a high-strength fiber impregnated with a synthetic resin and 0 which is rolled up to fade gently conical and is hollow. On the surface of the body is wound spirally a reinforcement tape which is narrower and is made of a high resistance fiber impregnated with synthatic resin to form a layer of reinforcement tape, whereby the strength of the body is increased. Usually, the reinforcing tape is rolled up

  spiral on the surface of the body of the cane, longitudinally

  to it, and at an angle of inclination of 20 to 30 0 with respect to a vertical line perpendicular to the axis

from the body.

  The reinforcement tape layer constructed as mentioned above is inflated radially outwardly of the body surface of the cane and is irregular. As a result, it is hard to apply a good paint to the surface of the fishing rod and also to print accurately and appropriately the name and characteristics by the use of a print on the screen. Furthermore, a movable guide 0 can be reliably attached to the body of the cane

fishing. -

  The present invention is directed to winding the reinforcing tape over the body of the fishing rod at a specified angle so that the layer of the reinforcing tape is substantially flush with the outer periphery of the body of the fishing rod because that it was noticed that the reinforcing tape wound at a specified angle on the surface of the cane body would bite into the outer perimeter of the body of the cane so as to

be substantially level.

  The present invention relates to a fishing rod whose body can be reinforced by means of a layer of a reinforcing tape and which can also be printed or painted accurately on its outer periphery, while allowing reliable attachment a guide

mobile if you wish.

  The fishing rod of the present invention is characterized in that it comprises a body made of a sheet

  pre-impregnated high-strength fiber which is

  a synthetic resin which is coiled to gently taper and is hollow, and a reinforcing layer of a smaller ribbon of high strength fiber which is impregnated with synthetic resin, which ribbon is wound spiral

  on the body of the cane, integrally with it.

  The reinforcing tape is wound in a long spiral

  to the body of the fishing rod and at an angle of inclination of 50 to 80 with respect to a vertical line perpendicular to the axis of the body to thereby form the layer of the reinforcing tape so that the outer surface of this layer is placed to be substantially level with or of a diameter substantially equal to

  outer circumference of the fishing rod body.

  The reinforcing tape is wound on the body of the fishing rod at an angle of inclination of 50 to 80 so as to bite in the outer periphery of the body of the

  the fishing rod and its binding force allows the fiber.

  high strength to pass from one side to another in the direction of the width of the ribbon, so the ribbon can easily

  to extend along the outer perimeter of the body and

  ment level to him. As a result, the reinforcing tape is wrapped around the body of the cane and pressed, for example, by means of a cellophane tape and heated under pressure, to thereby allow the layer of reinforcement tape to be placed so as to have a diameter substantially equal to the outer periphery of the body of the cane

fishing.

  Therefore, the fishing rod according to the invention can have a reinforced body, on which a print or paint can be easily and accurately applied and a movable guide, even when mounted,

  can be fixed reliably.

  The invention will be better understood, and other purposes, features, details and advantages thereof

  will become clearer during the description

  explanatory document which will follow with reference to the accompanying schematic drawings given solely by way of example illustrating an embodiment of the invention and in which: - Figure 1 is a partial front view of an embodiment of a cane fishing tackle according to the invention; - Figure 2 is an enlarged sectional view of its main part; and - Figure 3 is a perspective view showing

  a method of manufacturing the fishing rod.

  A fishing rod shown in FIGS. 1 to 3 is constructed so that a pre-impregnated sheet 11, comprising a sheet of parallel yarns of a high-strength fiber, impregnated with synthetic resin, is wound up several times on a bar forming conical core S tapering gently to form a hollow cylindrical body 1, on the periphery of which and longitudinally to which is spirally wound a reinforcing tape 2 which comprises a sheet of parallel son in a high strength fiber 21 longitudinally and parallel to the body 1 to thereby form a layer 2a of the reinforcing tape. In addition, a pre-impregnated sheet coated with a thin sheet of a light scrim can of course

  be used for the pre-impregnated sheet 11.

  The winding angle θ of the reinforcing strip 2 around the outer circumference of the body 1 with respect to a vertical line perpendicular to the axis of the body 1 is an inclination angle of 50 to 80, preferably 60 to 70 so that the reinforcing tape 2 is wound on the outer periphery and longitudinally to the body 1 with a predetermined binding force. Thus, the reinforcing tape is attached to the surface of the body 1 in a fashionable manner and the bonding force allows the high-strength fiber of the ribbon 2 to move in width thereof along the outer periphery of the ribbon. body 1 of

the stem.

  In this case, however, the reinforcing tape 2 can not be expected to lie completely in the outer periphery of the body 1. Therefore, the tape 2, when wound up, is slightly inflated radially towards the body. outside of the outer periphery of the body 1. This inflated portion, when the body 1 o is wound up the reinforcing tape 2 is heated and molded under pressure, can be pressed into the body 1, and thus the outer surface of the ribbon 2, after molding , is substantially

  level with the outer perimeter of the body 1.

  The body 1 is molded so that a ribbon of cellophane is wound, so as to cover the outer periphery of the body 1, the body 1 and the ribbon 2 are very tightly bound under pressure on the bar S forming a soul and then are heated in a heating oven, thereby hardening the synthetic resin. Therefore, the body 1 and the reinforcing tape 2 are one with the other

  and are positioned to have substantially equal diameters.

  During the above molding, the binding force from the winding force and the contraction force of the wrapped ribbon of cellophane presses the ribbon 2 onto the body 1 radially inward, thus the high strength fiber 21 which forms the ribbon 2 is shifted to expand in width, outwards and becomes less thick on both sides in width of the ribbon 2, so the outer surface of the ribbon 2 is substantially

  level with the outer perimeter of the body 1.

  This phenomenon can be obtained by forming the ribbon 2 with the sheet of parallel threads and by winding it to a

tilt angle from 50 to 80.

  The reason for the winding of the ribbon 2 at an angle of inclination of 50 to 80 lies in the fact that,

  for example, when the ribbon 2 is wound at an inclination angle

  80 or more, the coiled ribbon reinforcement 2 is inflated at its two edges in width to form folds. Therefore, the body 1 has not only a bad appearance but it can not print well or paint accurately on its outer periphery. In the case where the reinforcing tape 2 is wound at an angle of inclination of 50 or less, it does not bite well in the body 1 and the high-strength fiber of the ribbon 2 moves with difficulty in the width direction, ribbon 2 is therefore inflated and irregular compared

  external perimeter of the body 1. Therefore, the impres-

  precise paint or paint can not be obtained and the moving guide, if used, can not be

Reliably.

  The reinforcement tape 2, as can be seen in FIGS. 2 and 3, is constructed so that a sheet of a large number of fibers parallel longitudinally to the tape 2 are impregnated with a synthetic resin, its width being about 3 to 15 mm and its thickness of about 0.015 to 0.15 mm. A desired ribbon is used

  which corresponds to the diameter of the body 1 and to the pitch of

reinforcement tape.

  - On the other hand, the reinforcing tape 2, to which a predetermined load is applied, is sequentially wound on the body 1. In addition, the body 1, after being molded by heat treatment under pressure is removed from the bar S and is transferred following the process. In addition, in the embodiment shown in the drawings, a reinforcing tape is used, but, for example, two reinforcing tapes may also be wound in a crisscross manner, thereby allowing the tape to be substantially level with

the surface of the body 1 of the cane.

  Alternatively, the pre-impregnated layer 11 may be wound so that the parallel wire sheet is oriented longitudinally with respect to the fiber, and a parallel wire sheet of a carbon fiber pre-impregnated with synthetic resin is wound on the

  11 so that the fibers orient themselves circumferentially

  substantially to the body 1 to form an outer layer, the reinforcing tape 2 may be wound spirally or in a manner that intersects the outer layer. Thus, the winding condition of the ribbon 2 becomes apparent or disappears according to the direction of irradiation of the

light.
