Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mounting structure for a top guide in a fishing rod.

[0002]

2. Description of the Related Art In general, a top guide is attached to a head rod by directly bonding a mounting tube of the top guide to a tip of the head rod. However, if the top guide is attached to the tip of the tipping rod in the tipping rod for storing the tipping rod in the tipping rod, the tipping rod will not come off from the rear of the tipping rod, causing a maintenance problem.

[0003] As a top guide to solve such a problem, a male screw cylinder having a smaller diameter than the inner diameter of the tip of the ear-holding rod and having an external thread engraved on the outer circumference is fixed to the tip of the tip of the tip of the tipping rod of the through-hole. There is known an external thread in which a female screw engraved on the inner periphery of a mounting cylinder for a top guide is screwed to the external thread cylinder. Further, as disclosed in Japanese Utility Model Registration No. 2570549, there is also known a top guide which can be attached to and detached from the tip of a tip of a tipping rod in a through-hole.

However, in this conventional top guide mounting structure, since the entire inner surface of the male screw cylinder which is long in the rod axis direction is fixed to the tip of the tip rod which is most flexible, the male screw cylinder may be bent due to bending of the rod or the like. There is a possibility that fishing may not be possible due to peeling on the rod.

In addition, since the entire inner surface of the long male screw cylinder is fixed to the tip of the spike, stress is concentrated on this portion and it is easy to break. If the tip rod is broken, the top guide cannot be mounted unless the bonded male screw cylinder is peeled off from the broken part, so that there is also a problem that repair cannot be performed at a fishing spot or the like. Further, when the entire inner surface of the long male screw cylinder is fixed to the tip of the tip rod, the rigidity is increased as compared with the other parts, so that the condition of the fishing rod is changed.

[0006] Further, when the external thread is adhered to the external thread of the external thread cylinder or the tip of the external thread when the external thread pipe is bonded to the tip of the tip rod, the portion must be wiped off each time, so that productivity is reduced. There is a problem of getting worse.

The mounting seat 3 is formed by a cylindrical ring, and is fixed to the surface of the tip of the tip rod 1 by bonding with an adhesive, caulking or the like. The mounting seat 3 has front and rear ends 3a and 3b to which the top guide 5 and the male screw cylinder 4 can come into contact respectively.
As shown in FIG. 2, the mounting seat 3 may be formed by forming a flange 3d at the tip of a cylindrical ring 3c. This mounting seat 3 is formed by inserting the cylindrical ring 3c into the cavity of the tip rod 1 and bonding it to the inner surface thereof.
Can be fixed. In this case, the front and rear ends of the flange 3d serve as contact surfaces between the top guide 5 and the male screw cylinder 4, respectively.
In addition, the mounting seat 3 can be formed integrally with the tip rod 1.

The male screw cylinder 4 is a cylindrical body having an inner diameter larger than the outer diameter of the tip of the tip rod 1, and is movable in the rod axis direction behind the mounting seat 3 at the tip of the tip rod 1. It is loosely fitted. The front end 4a of the male screw cylinder 4 is the rear end 3 of the mounting seat 3.
b can be contacted. On the outer periphery of the male screw cylinder 4, a male screw 4b into which the top guide 5 can be screwed is formed. The outer diameter of the male screw cylinder 4 is smaller than the outer diameter of the mounting seat 3 than the inner diameter of the tip of the holding rod 2. For this reason,
When the top guide 5 is removed from the end of the rod, the tip rod 1 can be pulled out from the rear of the rod 2 with the mounting seat 3 and the male screw cylinder 4 attached.

The male screw cylinder 4 can be made of a synthetic resin, metal or the like, but can also be made of an elastically deformable elastic material such as polyurethane or rubber. When formed from an elastic material, the male screw cylinder 4 is expanded even when the mounting seat 3 is formed integrally with the tip of the tip rod 1 or after the mounting seat 3 is attached to the tip of the tip rod 1 in advance. It can be attached behind the attachment seat 3 on the tip pole 1 while being deformed.

The top guide 5 has a substantially cylindrical mounting cylinder 6. A female screw 6a that can be screwed into the male screw 4b of the male screw cylinder 4 is engraved on the rear inner peripheral surface of the mounting cylinder 6, and the central inner peripheral surface has an inner diameter slightly larger than the inner diameter of the spike rod 1. The fishing line guide ring 7 is fitted and fixed to the front inner peripheral surface. The female screw 6 a of the mounting cylinder 6 is formed such that its thread does not contact the surface of the mounting seat 3 at the tip of the tip rod 1. The front end 3a of the mounting seat 3 is provided between the rear inner peripheral surface of the mounting cylinder 6 and the central inner peripheral surface.
Contact surface 6b is formed. The fishing line guide ring 7 is formed so that the inner diameter thereof is smaller than the inner diameter of the tip of the tip rod 1 in order to reduce the sliding resistance of the fishing line guided in the top guide 5. The fishing line guide ring 7 is made of, for example, abrasion-resistant hard material such as ceramic or metal.

The top guide 5 is put on the tip of the spike rod 1 from above the mounting seat 3 and is turned in one direction to be screwed into the male screw cylinder 4 behind the mounting seat 3. Thereby, the top guide 5 is attached to the mounting seat 3 together with the male screw cylinder 3.
The top guide 5 is attached to the tip of the spike rod 1 by this clamping force. When the top guide 5 is turned in the opposite direction, the screwing of the top guide 5 and the male screw cylinder 4 is released, and the top guide 5 can be removed from the tip of the tip rod 1.

In addition, on the outer peripheral surface of the mounting cylinder 6 of the top guide 5, a long groove-shaped non-slip groove 6c extending in the axial direction of the tip rod 1 is formed. The non-slip groove 6c is for preventing slippage when the top guide 5 and the male screw cylinder 4 are screwed together. The non-slip groove 6c is not limited to the long groove in the illustrated example.
Known slip prevention means such as a knurl groove and an uneven portion can be used. Further, one or both of the contact surfaces formed by the rear end 3b of the mounting seat 3 and the front end 4a of the male screw cylinder 4 are formed in a rough surface, and when the top guide 5 and the male screw cylinder 4 are screwed together. It is desirable that the male screw cylinder 4 be kept from rotating.

Embodiment 2 The rod on which the top guide is provided is an outer fishing rod through which a fishing line passes outside the rod, and as shown in FIG. ing. The head rod 1 is inserted into the hollow of the ear rod 2 from the opening at the rear end,
It is pulled out of the front opening when used. When the rear end of the head rod 1 is locked to the front end of the ear rod 2, the head rod 1
Is completed.

As shown in FIG. 3, the top guide mounting structure includes a mounting seat 3 provided at the tip of the tip rod 1 and a male member slidably fitted slidably to the base side of the mounting seat 3 of the tip rod 1. It comprises a screw cylinder 4 and a top guide 5 which can be screwed into the male screw cylinder 4 provided on the mounting seat 3 from the tip end of the tip rod 1, and these constitute a top guide device.

The mounting seat 3 is formed at the tip of the tip rod 1 in the shape of a truncated cone having an outer diameter larger than its outer diameter, and is formed integrally with the rod body when the tip rod 1 is formed. More specifically, the mounting seat 3 is formed by winding a prepreg sheet cut into an elongated triangle around the tip of the rod main body of the tip rod 1, and baking the prepreg sheet together with the tip rod 1 by a conventional method. The mounting seat 3 is formed in a truncated cone shape, and has an inclined surface 3e that is inclined from the tip end side of the spike rod 1 toward the base side. The mounting seat 3 may be formed separately from the tip rod 1 and then fixed to the tip of the tip rod 1 by bonding with an adhesive, caulking, or the like.

As shown in FIGS. 3 and 4, the male screw cylinder 4 is a cylinder having an inner diameter that is larger or smaller than the outer diameter of the tip of the tip rod 1, and has a slot 8 in the generatrix direction. By forming, it is formed in the shape of a half cylinder. Also,
A notch 10 consisting of a V-shaped groove for forming a hinge 9 is formed as required on the generatrix opposite to the slit groove 8. By forming a plurality of notches 10, three or more half-tubular portions may be formed. Thereby, the male screw cylinder 4
Is the spike rod 1 in which the mounting seat 3 is already provided,
By expanding the male screw cylinder 4 using the slot 8 and the hinge 9, the male screw cylinder 4 can be loosely fitted on a rod behind the mounting seat 3.

A conical surface 4c whose inclination is gentler than the inclined surface 3e of the mounting seat 3 is formed on the inner periphery of the front part of the male screw cylinder 4, and the conical surface 4c covers the inclined surface 3e of the mounting seat 3. The front edge of the conical surface 4c is the inclined surface 3e of the mounting seat 3.
Is in contact with

On the outer periphery of the male screw cylinder 4, a male screw 4b for screwing the top guide 5 is cut. The outer diameter of the male screw cylinder 4 is smaller than the outer diameter of the mounting seat 3 than the inner diameter of the tip of the holding rod 2. For this reason, when the top guide 5 is removed from the tip of the tip rod 1, the tip rod 1 can be pulled out from the rear of the holding rod 2 with the attachment seat 3 and the male screw cylinder 4 attached. However, since the male screw cylinder 4 can be removed from the tip rod 1, the tip rod 1 can be pulled out from the holding rod 2 only by forming only the mounting seat 3 to have a small diameter.

The male screw cylinder 4 is made of an elastically deformable elastic material such as polyurethane or rubber, so that the male screw cylinder 4 can be expanded and deformed from the mounting seat 3 on the tip rod 1 without providing the slot 8 or the like. Can also be mounted rearward.

The top guide 5 has a mounting cylinder 6. A female screw 6a that can be screwed into the male screw 4b of the male screw cylinder 4 is engraved on the inner peripheral surface of the mounting cylinder 6, and a fishing line guide ring 7 is fixed to the front outer surface. In order to reduce the sliding resistance applied to the fishing line, an inner ring 7a made of, for example, ceramic or metal, which is a wear-resistant hard material, is fitted and fixed inside the fishing line guide ring 7. The female screw 6 a of the mounting cylinder 6 is formed such that its thread does not contact the surface of the mounting seat 3 at the tip of the tip rod 1.

The top guide 5 is placed on the tip of the spike rod 1 from above the mounting seat 3, and is turned in one direction to be screwed into the male screw cylinder 4 behind the mounting seat 3. As the screwing proceeds, the male screw cylinder 4 expands toward the inner peripheral surface of the mounting cylinder 6 along the inclined surface 3e of the mounting seat 3.
As a result, the top guide 5 clamps the mounting seat 3 together with the male screw cylinder 4 from the front and rear thereof, and the clamping force causes the top guide 5 to be fixed to the tip of the tip rod 1. When the top guide 5 is turned in the opposite direction, the top guide 5 and the male screw cylinder 4 are rotated.
And the top guide 5 can be removed from the tip of the tip rod 1.

In addition, one or both of the inclined surface 3e of the mounting seat 3 and the conical surface 4c of the male screw cylinder 4 are formed in a rough surface, and when the top guide 5 and the male screw cylinder 4 are screwed together, the male screw cylinder 4 is formed. It is desirable to keep the screw cylinder 3 from rotating.

[0032]

According to the first aspect of the present invention, the following effects can be obtained.

At the tip of the tip rod, only the mounting seat is fixed, and the male screw cylinder and the mounting cylinder of the top guide only clamp the mounting seat from the front and back. There is no problem that the guide peels off from the rod, and it is possible to prevent the rod from breaking due to the concentration of stress on the mounting portion of the top guide or the change in the condition of the rod due to an increase in local rigidity.

Even if the tip of the tip rod is broken during fishing, the top guide can be attached only by forming a mounting seat on the tip of the tip rod with an adhesive or the like, and therefore, emergency repair at the fishing spot is possible. Becomes possible.

Even if the adhesive protrudes when the mounting seat is adhered to the tip of the tip of the ear tip, the mounting seat and its surroundings are covered by the mounting cylinder of the top guide and the male screw cylinder, so that the protruding adhesive does not have to be wiped off. However, the product value is improved without impairing the commercial value.

Since the male screw cylinder is screwed into the mounting cylinder of the top guide together with the mounting seat, the base end side of the mounting cylinder of the top guide can be subjected to a smoothing process, thus preventing the fishing line from becoming entangled. Can be easily removed even when the fishing line is entangled.

According to the second aspect of the present invention, since the outer diameters of the mounting seat and the male screw cylinder are formed to be smaller than the inner diameter of the tip of the earpiece, if the mounting cylinder of the top guide is removed from the male screw cylinder, The head rod can be pulled out from the rear end of the head holding rod, and maintenance and cleaning of the head rod can be easily performed.

According to the third aspect of the present invention, since the male screw cylinder is composed of at least two half-cylinder sections, the male screw cylinder is moved to the base side from the mounting seat of the ear rod after the mounting seat is mounted on the ear rod. The fitting can be slidably loosely fitted, so that the mounting seat can be integrally formed at the tip of the tip when the tip is formed, and the productivity of the pole can be increased.

According to the fourth aspect of the present invention, since the male screw cylinder is made of an elastic material, the male screw cylinder can be elastically deformed after the mounting seat is attached to the tip rod and can be loosely fitted to the tip rod. Therefore, it is possible to integrally form the mounting seat at the tip of the tip rod at the time of molding, thereby improving the productivity of the rod.

According to the fifth aspect of the present invention, since the outer diameter of the mounting seat is formed smaller than the inner diameter of the tip of the ear-holding rod, the mounting cylinder of the top guide is removed from the male screw cylinder and the male screw cylinder is connected to the tip. By removing the head from the rod, the head can be pulled out from the rear end of the rod, and maintenance, cleaning, and the like of the head can be easily performed.

According to the invention of claim 6, the following effects can be obtained.

Since the base of the mounting seat is formed on an inclined surface having a small diameter toward the base, the male screw cylinder rides on the inclined surface according to the amount of screwing with the mounting cylinder of the top guide and moves to the outer peripheral side. . Therefore, the screwing force between the mounting cylinder of the top guide and the male screw cylinder is increased, and the top guide can be firmly attached to the tip.

Since the male screw cylinder moves on the inclined surface and moves to the outer peripheral side according to the screwing amount with the mounting cylinder of the top guide, the external diameter of the tip of the tip rod and the internal diameter of the mounting cylinder of the top guide are different. Sharing can be achieved without being affected by differences.
