Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod characterized by a nut body of a reel fixing device for mounting and fixing a reel. Therefore, the fishing rod may be a through fishing rod or an outer fishing rod.

[0002]

2. Description of the Related Art In a fishing rod provided with a reel fixing device for mounting a reel by screwing a male screw and a female screw, when a fishing rod is operated by gripping a reel mounting part, a feeling of gripping without touching an exposed male screw part is achieved. In general, the nut body to be screwed to the nut body may be formed to be longer in order to improve it. However, there are cases where the size of the reel to be used is substantially fixed, such as a casting rod, and the male screw portion of the reel fixing device may be originally short. In such a fishing rod, even a nut body having a length that does not expose the external thread portion can be relatively short. On the other hand, there is a case where it is desired to operate while holding such an area of the nut body. For this purpose, it is necessary to form the nut body as long as the width of the hand. In this case, it is conceivable that the female screw portion is formed longer than necessary over the entire length of the nut body.

[0003]

However, in general, fishing rods are manufactured by injection molding a synthetic resin material when forming a screw on a member for cost reduction and weight reduction. Then the stiffness is not very high. Therefore, as described above, if the female screw portion is stretched as it is regardless of the portion not used for screwing, the elongated female screw portion is easily bent. As a result, when a load acts on the fishing rod while holding the nut body,
The end of the elongated internal thread presses against the surface of the rod pipe, and stress concentration occurs at this abutting portion, so that the rod pipe is easily broken. Further, since the inner surface of the elongated female screw portion is uneven, dust easily accumulates between the inner surface of the elongated female screw portion and the surface of the rod pipe. Further, when performing a maintenance operation such as washing with water for cleaning the dust and the like, it is difficult to perform the maintenance operation due to unevenness of the screws.

Accordingly, an object of the present invention is to provide a fishing rod having a nut body that can be used also as a grip portion and that can prevent stress concentration when a load is applied to the fishing rod. It is still another object of the present invention to provide a fishing rod in which dust is unlikely to enter the nut body and is easy to clean even if it enters.

[0005]

SUMMARY OF THE INVENTION In view of the above object, according to the present invention, a nut member provided with a moving hood of a reel fixing device at one end side is provided with a flexible member on the outside and the flexible member on the inside. A holding member for holding the elastic member, the member on the one end side of the holding member and the member on the other side are formed of different materials, and the one end member is formed of a synthetic resin material, A female screw is provided in a predetermined area on the inner surface, the other side member has a higher longitudinal elastic modulus than the one end side member, and a gap is provided between the other side member and the outer surface of the rod pipe. Provide fishing rods.

Since the nut body has a flexible member on the outside, the gripping feeling when gripping can be improved, and since the nut body has a holding body, the form of the flexible member can be held and it is easy to grip. Further, the holding member is formed of one material on one end side and the other side member with different materials, and the other side member which does not need to be provided with the internal thread has a much higher longitudinal elastic modulus, and while the rigidity as the holding body is greatly increased, A gap is provided between the pipe surface and the nut body, which is the position of the reel fixing device, so it is close to the base of the rod, and even if a load is applied to the fishing rod, the rod pipe in this part hardly bends. It is possible to prevent the nut body end portion and the rod tube from strongly pressing each other, thereby preventing stress concentration.

According to a second aspect of the present invention, the inner diameter of an end of the other side member remote from the one end side member is small, and the inner diameter of a region entering the inside from the end side is formed large. Can be released from the position of the reel fixing device.
The described fishing rod is provided. In order to reduce the inner diameter of the other end member farther from the one end member, the gap between the rod member surface at that position is small, and dust and the like hardly enter from this position.
Even if dust enters, the inner diameter of the region entering from the end is large and the nut body can be separated from the position of the reel fixing device, so the nut body separated from the reel fixing device position However, a large gap can be secured between the inner surface of the internal area of the other side member and the surface of the rod pipe, and cleaning is facilitated by pouring water from the one end side which is the moving hood side of the nut body, Removal of dust is also facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments shown in the accompanying drawings. FIG. 1 is a longitudinal sectional view of a hand portion of a fishing rod according to the present invention, FIG. 2 is an enlarged view of a main part thereof, FIG. 3 (a) is a transverse sectional view taken along line CC,
(B) is a transverse sectional view along DD. This fishing rod is a casting rod, and the rod tube 10 is made of fiber reinforced resin (FRP) reinforced with a reinforcing fiber such as carbon fiber using a thermosetting resin or a thermoplastic resin such as an epoxy resin as a matrix. The fixing hood 16 of the reel fixing device for mounting and fixing the reel is formed on one end side (rear end side), and the reel fixing device main body portion 24 having the male screw 24M formed in a predetermined range on the other end side (front end side), A synthetic resin such as a polyamide resin or an ABS resin is formed by injection molding, and the rod tube 10 is inserted through the synthetic resin to be positioned at an appropriate position on the fishing rod hand and fixed by bonding or the like.

A nut body 19 provided with a movable hood 18 at one end (in this case, a rear end) is disposed in front of the fixed hood 16 so as to face the fixed hood 16.
In this embodiment, the moving hood 18 is formed integrally with the nut body and has a rotationally symmetric shape. However, the moving hood 18 is formed separately and locked together so as to be movable in the longitudinal direction of the rod pipe, and its opening does not rotate. The form which always faces a fixed hood may be sufficient. Further, the nut body can be rotated at a certain position without moving back and forth with respect to the rod pipe 10, and only the moving hood can be moved back and forth, that is, a so-called frame feed type (of course,
This is excluded in claim 2).

A trigger 14 is provided on the reel fixing device main body 24 at a position substantially opposite to the fixed hood in the radial direction (lower side). The trigger 14 is provided immediately after the reel fixing device main body 24 to near the rear end of the fishing rod. A rear grip 12 is formed in the area. Usually, a gripping member of a flexible member such as natural or artificial cork or foamed EVA is provided here.

The nut body 19 extends over a predetermined length range L between a member 22A close to a moving hood 18 and a member 22B on the other side, which will be described later, so that it can be used as a front grip. A flexible member 20 similar to the grip portion 12 is provided on the outside. The length range L is about 50 mm or more and about 150 mm or less, and is preferably about the width of a human hand. On the other hand, a holding body 22 for holding the flexible member 20 is provided inside.

The holding body 22 has a member 22A near the moving hood 18 and a member 22B on the other side.
On the inner surface of the member 22A near the moving hood 18, a female screw 22F for screwing with the male screw 24M is provided. In this embodiment, the moving hood 18 is formed integrally with the member 22A as described above. I have. The member 22A and the movable hood are formed by injection molding a synthetic resin such as a polyamide resin or an ABS resin. In the casting rod, since the variation width of the leg size of the reel to be mounted is relatively small, the screwing length can be relatively short. Therefore, the area where the male screw 24M is provided is also short, and the area of the female screw 22F is also short.

Therefore, in order to secure the length L for using the nut body 19 also as a gripping member, a metal material such as brass, stainless steel, aluminum or the like which does not easily rust or a ceramic material is used. Side member 22B
Is extended. In extension, a region on the member 22A side of the other member 22B, which is a cylindrical member, is fixed by bonding or the like so as to cover the outer periphery of the member 22A. The inner surface 22Ba of the extension side end of the member 22B has a smaller inner diameter than the inner side region (here, the rear side region), thereby making it difficult for dust and the like to enter from the outside.

As a result, the gap δ between the inner surface of the extended end (the inner surface of the front end of the nut body in this example) and the surface of the rod tube is small, and the gap between the inner surface of the rod tube and the surface of the rod tube is large in the rear region. As an example, the tip gap δ is about 0.75 mm, and about 2.5 mm in the rear area. The tip clearance δ is about 0.5 mm or more to prevent pressing on the rod pipe surface, and 0.8 m
m or less to prevent intrusion of dust and the like. However, the large gap in the rear region may be maintained as it is at the end.

If the member 22B is formed of the above-described metal or ceramic, the longitudinal elastic modulus is much higher than that of synthetic resin, so that the rigidity can be significantly increased. Therefore, if the above-mentioned gap δ is provided, the nut body 19 is located at the base of the fishing rod and is hardly bent. 10 can be prevented from being pressed.

In this embodiment, the nut 19 can be rotated to unscrew from the male screw 24M, and can be moved forward of the fishing rod together with the movable hood 18. In this way, the inside of the nut body, which is opposite to the front end of the nut body for preventing intrusion of dust, can be washed away from the large opening at the end of the moving hood (in this case, the actual hood is the moving hood) by a water flow or the like. It will be easier.

FIG. 4 is a longitudinal sectional view of a main part of a fishing rod according to another embodiment of the present invention, and corresponds to FIG. The difference from the first embodiment is that the member 22A close to the moving hood 18 and the member 22B 'on the other side are not overlapped, but their ends are butted together to form a holder 22'. . An adhesive may be used at this abutting portion. A flexible member 20 is provided on the outer periphery extending between the member 22A and the member 22B 'to form a nut body 19'.

In this embodiment, the front end of the member 22B 'made of metal or the like does not have an annular convex portion on the inside, and the rod tube 1
It is not configured to reduce the gap with zero. That is, the flexible member 20 provided over the member 22A performs a holding coupling operation with respect to the member 22B ′ having a gap between the rod tube 10 and the member 22B ′, and the member 22A has a gap with the end of the member 22A. Because of the abutted configuration, it is difficult to bend in cooperation with the high rigidity of the member 22B 'itself formed of a material having a high longitudinal elastic modulus, but the bending rigidity is inferior to that of the first embodiment. It is. However, as long as the inner periphery of the front end of the member 22B 'does not press the rod tube 10, the inner periphery of the distal end may be protruded to make it difficult for dust and the like to enter from the outside.

In the above description, a casting rod is taken as an example of a fishing rod, but other fishing rods may be used.

[0020]

As is apparent from the above description, claim 1
According to this, it is possible to provide a fishing rod having a nut body that can be used as a grip portion and that can prevent stress concentration when a load acts on the fishing rod. According to the second aspect, in addition to the above effects, dust is less likely to enter the nut body, and even if it enters, cleaning becomes easier.
