Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a rod butt structure for a fishing rod.

(Prior Art) In general, in a fishing rod, a butt plug consisting of a disc-shaped closing part and a threaded cylinder part with a thread on the inner surface is screwed onto the bottom of the rod body formed hollow. In addition to closing the rod butt, a cylindrical grip is attached to the outer periphery of the rod butt of the rod body to make it easier to grip the rod butt.

However, because the tail plug is screwed in with such force that it can be easily attached and removed by the angler's hands, there is a problem in that it tends to loosen, and this loosening makes it easy for the tail plug to be lost.

(Problems to be solved by the invention) The present invention attempts to solve the problem that the butt plug easily loosens in the conventional rod butt structure.
Utilizing the grip, the grip is formed of a flexible material, and the grip is provided with a lip that is elastically deformed by screwing the butt plug,
By fixing the butt plug with the elastic restoring force of this lip, it is possible to prevent the butt plug from loosening.

(Means for Solving the Problem) Therefore, the present invention provides a rod butt structure for a fishing rod, in which a butt plug is screwed onto the rod butt of the rod body, and a grip is attached to the outer periphery of the rod body. A stepped portion is provided between the outer periphery of the threaded part of the butt plug and the outer periphery of the rod butt part of the rod body to which the grip is attached, and the grip is formed of a flexible material, so that the butt part of the grip is An inward lip extending radially inward and intervening between the opening end surface of the butt plug and the step portion is provided on the end edge of the plug, and is elastically deformed by screwing the butt plug.

(Function) A butt plug is screwed into the butt of the rod body, and the open end surface of the butt plug is brought into contact with the lip, and the lip is elastically deformed and pressed against the stepped portion, and the elastic restoring force of the lip causes the lip to be pressed against the step. The butt plug was fixed to prevent it from coming loose.

(Example) An example of the rod butt structure of the present invention will be described below based on the drawings.

The rod shown in FIG. 2 includes a rod-like rod butt 11 at the hand portion of a hollow rod body 1, and a disk-shaped closing portion 21 that protrudes outward in the axial direction from the peripheral edge of the closing portion 21. A butt plug 2 consisting of a threaded cylindrical portion 22 with a thread on the inner surface is screwed on to close the rod butt 11, and a cylindrical grip 3 is inserted around the outer periphery of the rod butt 11 of the rod body 1. It is fitted so that it is easy to grip the butt part of the rod.

In the embodiment shown in FIG. 1, however, a support cylinder 4 having a threaded portion 41 having a smaller diameter than the outer diameter of the rod butt 11 on the outer periphery of one end is inserted into the inner periphery of the rod butt 11 of the rod body 2. Fit the threaded portion 41 into the rod butt 11.
A stepped portion 5 is provided between the threaded portion 41 and the outer periphery of the rod butt 11 of the rod body 1 to which the grip 3 is attached, and the grip 3 is made of a flexible material such as rubber. The grip 3 is formed of a flexible material, and extends radially inward on the edge of the grip 3 on the side of the butt plug 3 to intervene between the open end surface 23 of the butt plug 2 and the stepped portion 5, and 2, an inward lip 6 that is elastically deformed is integrally provided.

In the above configuration, the stepped portion 5 utilizes the edge of the rod butt 11, and the rod butt edge is used as the stepped portion 5.

Further, the lip 6 is formed integrally with the grip 3 during molding, so that the grip 3 is attached to the rod butt 11.
The inner surface of the lip is formed so as to come into contact with the stepped portion 5 when inserted into the outer periphery of the lip.

Further, the butt plug 2 has a through hole 2 in the closing portion 21.
4, and a buffer body 7 made of a flexible material such as rubber is held in the through hole 24 portion.

Note that a water drain hole 71 is provided in the center of this buffer body 7.

Further, the rod body 1 is formed by winding a prepreg formed by impregnating high-strength fiber with a synthetic resin, and the rod body 1 is formed by winding a prepreg formed by impregnating high-strength fiber with a synthetic resin.
is made of lightweight material such as aluminum.

The present invention is constructed as described above, and the grip 3 is inserted into the outer periphery of the rod butt 11 of the rod body 1, and the inner surface of the inward lip 6 provided on the grip 3 is brought into contact with the stepped portion 5. After that, the threaded cylinder part 22 of the butt plug 2 is
It is screwed into the threaded portion 41 of the support tube 4 attached to the rod butt 11, and the open end surface 23 of the butt plug 2 is brought into contact with the outer surface of the lip 6, and the tightening force of the butt plug 2 causes the lip 6 to tighten. is pressed against the stepped portion 5 to cause it to elastically deform, and the elastic restoring force due to the elastic deformation of the lip 6 is applied to the butt plug 2.

Since the butt plug 2 is reliably fixed by the elastic restoring force of the lip 6, loosening of the butt plug 2 can be prevented. Since it is sandwiched between the front grip 3 and the rod body 1, it is possible to reliably prevent the front grip 3 from shifting its position with respect to the rod body 1.

In the embodiment described above, the edge of the rod butt 11 of the rod body 1 was used as the stepped portion 5, but in addition, as shown in FIG.
An annular projection 43 having approximately the same diameter as the outer diameter of the rod butt 11 may be provided on the outer periphery between the threaded portion 41 and the fitting portion 42, and the outer surface of this annular projection 43 may be used as the stepped portion 5. .

In addition to being formed in an annular shape, the lip 6 may be formed in a plurality at predetermined intervals in the circumferential direction.

Further, the grip 3 may be made of rubber or may be made of a rubber-based contraction tube, and the material thereof is not particularly limited.

(Effects of the invention) As described above, the present invention provides a step between the outer periphery of the butt plug screwing part of the rod butt and the outer periphery of the grip attachment part of the rod butt, and utilizes a grip attached to the outer periphery of the rod butt. The grip is formed of a flexible material, and extends radially inwardly on the end edge of the grip on the butt plug side and interposes between the opening edge of the butt plug and the stepped portion, and Since an inward lip that is elastically deformed when the plug is screwed in is provided, the butt plug can be easily attached and taken off by the angler's hands. When applied to the plug, this elastic restoring force can securely fix the butt plug.
This can reliably prevent the butt plug from loosening.

Furthermore, since the grip is made of a flexible material, it is possible to prevent the hand gripping the fishing rod from slipping, and the grip is even more comfortable. Since the grip is sandwiched between the two, it is possible to reliably prevent the grip from shifting relative to the rod body, and it is possible to prevent the grip from becoming uncomfortable.
