Description

Splicing fishing rod
Technical Field
The invention relates to a splicing fishing rod.
Background
Conventionally, in a splicing fishing rod in which a plurality of rods are connected, a fishing rod in which the rod diameter of the connecting portion is constant and a fishing rod in which the rod diameter of the connecting portion is varied are known as the configuration of the connecting portion. In the case of taper engagement, as shown in patent document 1, for example, a taper angle of a male side is generally set larger than a taper angle of a female side.
Patent document 1: japanese patent application laid-open No. 2011-115176.
However, the following problems are encountered in the conventional taper-jointed splicing fishing rod: since the taper angle of the male side is set smaller than that of the female side, the end of the male side rod is inserted into the end of the female side rod head excessively, so that the end of the male side rod is engaged and fixed to the inner circumference of the female side rod.
On the contrary, when the taper angle of the male side is larger than that of the female side, the surface pressure between the male side and female side of the rod body of the connecting portion becomes insufficient, and the taper fixing force becomes insufficient, so that the rod body is liable to come off.
Further, in the linearly jointed splicing fishing rod, since the rod head side rod body is difficult to be fitted into the rod head side end portion of the rod base side rod body at the time of splicing due to thermal expansion accompanying temperature change, and in addition, it is difficult to be taken out, there is room for improvement in this point.
Disclosure of Invention
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a splicing fishing rod capable of preventing the occurrence of consolidation accompanying the insertion, ensuring the fixing force of taper splicing, and preventing the rod body on the rod head side from coming off after the rod body on the rod base side is inserted.
(1) The invention is a continuous fishing rod, the rod base side end of the rod body of the rod head side is embedded into the rod head side end of the rod body of the rod base side for connection, characterized in that, a male taper part gradually reducing from the rod head side to the rod base side is formed on the outer surface of the rod base side end of the rod body of the rod head side, a female taper part gradually reducing from the rod head side to the rod base side is formed on the inner surface of the rod head side end of the rod body of the rod base side, and the length of the female taper part in the rod shaft direction is set to be shorter than that of the male taper part.
According to the splicing fishing rod of the present invention, since the female taper portion and the male taper portion are shorter than each other in the rod axial direction, the outer surface of the rod base side end portion of the rod body on the rod head side does not contact the inner surface of the rod head side end portion of the rod body on the rod base side. That is, the rod base side end of the male cone of the rod head side rod body is cone-jointed and embedded in the state of passing through the female cone of the rod base side rod body and penetrating to the rod base side. Thus, in the present invention, the accuracy of the taper joint and the fixing force of the taper joint can be improved. Further, the male taper portion can be fixed to the female taper portion at an appropriate taper engagement position without being excessively inserted. That is, it is possible to prevent the rod bodies from being fixed to each other by inserting the rod base side end portion of the male side into the rod head side end portion of the female side excessively, as in the case of the taper joining in the conventional case in which the taper angle of the male side is set to be larger than the taper angle of the female side.
In this way, in the present invention, since the connection system is based on the taper joint, it is possible to suppress the difficulty of insertion due to thermal expansion accompanying temperature change, and it is possible to prevent the occurrence of the solidification accompanying the insertion as in the conventional case. And the taper angle of the male taper part and the female taper part is consistent, so that the fixing force of the taper joint can be ensured, and the rod body at the rod head side after the rod body at the rod base side is inserted can be prevented from being released.
(2) The taper angles of the male tapered portion and the female tapered portion may be the same.
In this case, since the taper angles of the male taper part and the female taper part are the same, the fixing force of the taper joint can be ensured more reliably, and the rod head side rod body inserted into the rod base side rod body can be prevented from coming off.
(3) Preferably, the inner surface of the rod base side rod body which is continuously provided with the rod base side of the female tapered part is set to be smaller than the taper angle of the male tapered part formed on the rod head side rod body, and the end plug which is in frictional contact with the inner surface of the rod base side rod body is provided at the rod base side end part of the rod head side rod body.
In this case, since the end plug provided at the rod base side end of the rod body on the rod head side is in frictional contact with the inner surface of the rod body on the rod base side, a frictional feeling can be brought when the male tapered part and the female tapered part are tapered and joined.
(4) In the above-described aspect, a stepped surface having a reduced outer diameter and covered with a coating portion facing the tapered surface of the male tapered portion may be formed on the rod head side portion of the male tapered portion, and a part of the coating portion covering the stepped surface may be fitted inside the female tapered portion in a state where the male tapered portion and the female tapered portion are tapered.
In this case, when the male taper portion of the rod body on the rod head side is inserted into the female taper portion of the rod body on the rod base side to be connected, the coating portion of the rod body on the rod head side is engaged in a state of being inserted into the inner side of the female taper portion. In this case, the coating portion and the tapered surface of the male tapered portion are flush with each other, and high-precision taper joining can be performed, so that the connection completion state is improved, and the appearance as a splicing fishing rod can be improved.
According to the splicing fishing rod of the invention, the consolidation caused by the insertion can be prevented, the fixing force of the taper joint can be ensured, and the rod body at the rod head side after being inserted into the rod body at the rod base side can be prevented from dropping out.

In the present embodiment, a fishing rod for line throwing fishing will be described as an example of a splicing fishing rod. In the drawings, the proportions of the respective components may be appropriately changed as necessary in order to make the respective components have a size that can be recognized.
As shown in fig. 1 to 3, the splicing fishing rod 1 of the present embodiment is a splicing rod in which the rod base side end 2a of the rod head side rod body 2 is fitted into the rod head side end 3a of the rod base side rod body 3 to be connected.
Here, the number of the rod bodies to be connected as the splicing fishing rod 1 is not limited to two, and may be three or more. In the present embodiment, as the splicing fishing rod 1, a rod for enjoying fishing by providing a fishing line guide mechanism, not shown, in each rod body as needed and providing a reel in the rod body on the hand side as needed is targeted.
In the present embodiment, in the longitudinal direction of the butt fishing rod 1, the tip side (left side in the drawing) is defined as the rod head, the hand-held side (right side in the drawing) is defined as the rod tail, the longitudinal direction from the rod head to the rod tail is defined as the front-rear direction, the front side in the front-rear direction is defined as the rod head side, and the rear side is defined as the rod base side. In the present embodiment, the direction of the rod axis O wound around the central axis of the fishing rod is defined as the circumferential direction.
In addition, fig. 1 to fig. 3, for easy observation, the rod body 2 at the rod head side is shown as a side view, and the rod body 3 at the rod base side is shown as a longitudinal section view passing through the rod axis O.
The butt fishing rod 1 is a tubular rod in which both the rod head side rod body 2 and the rod base side rod body 3 are made of a fiber-reinforced resin in which a synthetic resin matrix such as epoxy resin is reinforced with a reinforcing fiber such as carbon fiber.
The rod body 2 at the rod head side is provided with: a rod body 20, and a connecting body 21 attached to the rod base side of the rod body 20. The outer surface of the rod base side end part 2A of the connecting body 21 is formed with a male taper part 2A which gradually shrinks from the rod head side to the rod base side. The male tapered portion 2A is located on the rod base side of the substantially center in the longitudinal direction of the connecting body 21. A coating portion 2B having an outer surface coated is formed on the connecting member 21 on the rod head side of the male taper portion 2A. The coating portion 2B is formed so that the outer diameter thereof increases from the rod head side toward the rod base side, and the outer diameter thereof decreases at a substantially middle portion in the longitudinal direction of the coating portion 2B so as to be continuous with the male taper portion 2A. The outer surfaces of the coating portion 2B and the male taper portion 2A are flush with each other.
The coating portion 2B of the connecting member 21 is formed to cover the coating material 23 with a predetermined thickness, and the coated coating material 23 and the outer surface of the male tapered portion 2A are smoothly continuous so as to be flush with each other. That is, the coating portion 2B is formed with a stepped surface 21a covered by the coating portion 2B having a smaller outer diameter than the male tapered portion 2A and being flush with the tapered surface of the male tapered portion 2A. In a state where the male tapered portion 2A and the female tapered portion 3A are taper-joined, a part of the coating portion 2B (part of reference numeral 2B) covering the stepped surface 21a is disposed in a state of being inserted inside the female tapered portion 3A (described later). (see fig. 3).
The inner surface of the rod head side end part 3A of the rod body 3 at the rod base side is formed with a female taper part 3A gradually shrinking from the rod head side to the rod base side. The female taper portion 3A is set to have a shorter length in the rod axis O direction than the male taper portion 2A. The taper angles θ 1 and θ 2 (see fig. 1) of the male taper portion 2A and the female taper portion 3A are set to be the same. In the continuous fishing rod 1, the female taper part 3A of the rod head side end part 3A of the rod base side rod body 3 is embedded with the male taper part 2A of the rod base side end part 2A of the rod head side rod body 2.
The taper angles θ 1 and θ 2 of the male taper portion 2A and the female taper portion 3A are, for example, about 2.0/1000.
In the rod base side rod body 3, the inner surface of the rod head side end part 3A has a linear part 3B with unchanged inner diameter which is continuously arranged with the rod base side of the female taper part 3A. That is, the linear portion 3B is formed on the inner surface extending in parallel to the rod axis O in a cross-section including the rod axis O of the rod body 3 on the rod base side.
The tip of the male tapered part 2A is formed with a retreating part 2c which is positioned inside the linear part 3B of the rod body 3 on the rod base side in a state of being fitted with the female tapered part 3A and is not in contact with the female tapered part 3A.
For example, as shown in fig. 3, in the connecting body 21 of rod head side rod body 2, the length dimension (joint dimension L1) along the rod axis O direction of the part inserted into the rod base side rod body 3 is set to 80mm, the length dimension (bore depth L2) along the rod axis O direction of the female taper part 3A is set to 60mm, and the retreat dimension L3 is set to 20 mm. By arranging the retreating part 2c, the end of the connecting body 21 of the rod head side rod body 2 is not contacted with the inner circumference of the rod base side rod body 3, thereby preventing the rod head side rod body 2 and the rod base side rod body 3 from being fixed.
The rod base side end part 2a of the rod body 2 at the rod head side is provided with an end plug 22 which is larger than the outer diameter of the rod base side end part 2a and is in friction contact with the linear part 3B, and the linear part 3B and the rod base side of the female taper part 3A of the rod body 3 at the base side are continuously arranged.
The end plug 22 is formed of an elastic member such as rubber, is provided continuously with the rod base side of the male tapered portion 2A, and projects radially outward from the outer surface of the male tapered portion 2A. In the present embodiment, the protrusion is formed over the entire circumference, but the protrusion is not limited thereto, and may be formed at least one portion of the circumference. The end plugs 22 are bent around the outer periphery of the corners of the rod base side. The outer diameter of the end plug 22 is set to be slightly larger than the inner diameter of the linear part 3B of the rod body 3 at the rod base side. For example, the outer dimension of the end plug 22 is set to be larger than the inner diameter of the linear portion 3B by, for example, 0.1 mm.
When the male taper part 2A of the rod body 2 at the rod head side is inserted into the female taper part 3A and connected, the end plug 22 is positioned in the range of the straight line part 3B and is in a state of contacting with the inner surface of the straight line part 3B.
Next, the operation of the splicing fishing rod 1 configured as described above will be described in detail with reference to the drawings.
As shown in fig. 1 to 3, in the splicing fishing rod 1 according to the present embodiment, since the female tapered portion 3A is shorter than the male tapered portion 2A in the rod axis O direction, the outer surface of the end portion of the rod base side end portion 2A of the rod head side rod body 2 is configured not to contact the inner surface of the rod head side end portion 3A of the rod base side rod body 3. That is, the rod base side end 2A of the male taper part 2A of the rod head side rod body 2 is engaged and embedded by taper in a state of being inserted through the female taper part 3A of the rod base side rod body 3 to penetrate to the rod base side.
Thus, in the present embodiment, the accuracy of the taper joining and the fixing force of the taper joining can be improved. Further, the male tapered portion 2A can be fixed at an appropriate taper engagement position without being excessively inserted into the female tapered portion 3A. That is, the outer surface of the rod base side end 2a of the rod head side rod body 2 is not contacted with the inner surface of the rod head side end 3a of the rod base side rod body 3, thereby preventing the consolidation, and the taper angle of the male side and the taper angle of the female side are set in the same way, thereby being capable of keeping the surface pressure of the rod bodies each other, and being capable of fully maintaining the taper fixing force.
In this way, in the present embodiment, since the connection method is based on the taper joining, it is possible to suppress difficulty in insertion due to thermal expansion accompanying temperature change, and to prevent the occurrence of consolidation accompanying insertion as in the conventional case. And by making the taper angle of the male taper part 2A and the female taper part 3A consistent, the fixing force of the taper joint can be ensured, and the rod head side rod body 2 inserted into the rod base side rod body 3 can be prevented from coming off.
In addition, in the present embodiment, the taper angles θ 1 and θ 2 of the male taper portion 2A and the female taper portion 3A are the same, so that the fixing force of the taper joint can be more reliably ensured, and the rod body 2 at the rod head side after being inserted into the rod body 3 at the rod base side can be prevented from coming off.
In addition, in this embodiment, the rod base side end 2A of the rod body 2 at the rod head side is provided with the end plug 22, the end plug 22 is larger than the outer diameter of the rod base side end 2A and frictionally contacts with the linear portion 3B, the linear portion 3B is continuously provided with the rod base side of the female taper portion 3A of the rod body 3 at the base side, so the end plug 22 provided at the rod base side end 2A of the rod body 2 at the rod head side becomes the state frictionally contacting with the inner surface of the linear portion 3B of the rod body 3 at the rod base side, thereby the male taper portion 2A and the female taper portion 3A are engaged with each other and friction feeling can be brought when being connected.
Further, in this embodiment, when the male taper part 2A of the rod head side rod body 2 is inserted into the female taper part 3A of the rod base side rod body 3 to be connected, the coating part 2B of the rod head side rod body 2 is engaged in the state of entering the inner side of the female taper part 3A. In this case, since the tapered surfaces of the coating portion 2B and the male tapered portion 2A are flush with each other and can be joined to each other with a high degree of accuracy, the finished state of the connection is good, and the appearance of the fishing rod 1 as a splicing rod can be improved.
In the splicing fishing rod of the present embodiment configured as described above, the rod head side rod body 2 inserted into the rod base side rod body 3 can be prevented from coming off, while preventing the fastening caused by the insertion, and securing the taper joining fixing force.
The embodiments of the splicing fishing rod according to the present invention have been described above, but these embodiments are provided as examples and are not intended to limit the scope of the invention. The embodiments may be implemented in other various forms, and various omissions, replacements, and modifications may be made without departing from the scope of the invention. The embodiments and modifications thereof include, for example, a mode which can be easily conceived by those skilled in the art, a substantially similar mode, and a mode within an equivalent range.
For example, in the above embodiment, the linear portion 3B is formed on the inner surface of the rod base side rod body 3 continuously provided on the rod base side of the female tapered portion 3A, but not limited to the linear surface, the retreat portion 2c not contacting the female tapered portion 3A may be provided on the rod base side of the male tapered portion 2A. In short, it is set to be at least smaller than the taper angle of the male taper part 2A formed on the rod head side rod body 2. For example, the tapered surface of the male tapered portion 2A may be inverted. That is, the reverse tapered portion may be formed as a tapered portion which is inclined so as to gradually separate from the rod axis O from the rod head side toward the rod base side.
In the above embodiment, the taper angles θ 1 and θ 2 of the male taper portion 2A and the female taper portion 3A are set to be the same, but the taper angles θ 1 and θ 2 are not necessarily the same.
Further, in the present embodiment, the end plug 22 which is in friction contact with the inner surface (the linear portion 3B) of the rod base side rod body 3 is provided at the rod base side end portion of the rod head side rod body 2, but the rod head side rod body 2 of the end plug 22 may be omitted.
In the present embodiment, the stepped surface 21a is formed on the male tapered portion 2A of the rod head side rod body 2 and the coating material 23 is coated on the stepped surface 21a, but the rod body may not have such a configuration of the stepped surface 21a and the coating portion 2B. Further, the opening end of the female tapered portion 3A may be bent so as not to be peeled off when the coating material 23 of the coating film is inserted into and removed from the female tapered portion 3A, and a step of the thickness of the coating film or more may be provided, and further, the taper angle of the tip side of the male tapered portion 2A may be reduced or a step of the thickness of the coating film or more may be provided.
