Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a fishing rod, and more particularly, to a fishing rod comprising a hollow rod body and a handle having a diameter larger than the diameter of the base end connected to the base end of the rod body.

(Prior Art) In general, in this type of fishing rod, when joining the handle to the rod body, an adhesive is applied to the joint of the rod body to the handle, and at the same time, adhesive is applied to the joint of the handle to the rod body. An insertion hole is provided in the joint portion, and the insertion hole portion is inserted into the joint portion of the rod main body, thereby making the joint via the adhesive.

However, since this conventional fishing rod has a simple fit-in structure, the adhesive deteriorates and the grip handle naturally slips out from the rod body while the fishing rod is used for a long period of time. Alternatively, there is a problem that play may occur at the joint between the handle and the rod body, and in the case of a fishing rod that is made up of multiple rod bodies with different diameters and tips joined together, it is difficult to insert the handle. Since the hole is passed through both ends, there is a problem that the handle cannot be securely fixed in a fixed position relative to the rod body.Also, since the handle is fixed with adhesive, Not only is it not possible to freely exchange a new handle or a handle of your choice, but you also have to attach a butt plug to the insertion hole and replace the small diameter rod body and tip that are connected to the tip of the rod body that connects to the handle. Since it is necessary to be able to drain water that has entered the rod body, there is a problem that the structure becomes complicated.

(Purpose of the invention) The purpose of the invention is to use a narrow tape made of high-strength fiber impregnated with synthetic resin, to form a thread integral with the rod body with this narrow tape, and to attach the handle by screwing it together. This allows for jointing.

(Structure of the invention) The structure of the invention is a fishing rod in which a handle having a diameter larger than the diameter of the hollow rod body is connected to the base end of the hollow rod body. A narrow tape made of high-strength fiber impregnated with synthetic resin is wound spirally around the joint with the grip handle at predetermined intervals.
A thread is formed integrally with the rod body by pressure firing, and the grip handle is connected to the joint portion by threading, so that the grip handle can be removed from the rod body and the rod body and handle can be connected to each other by threading. This eliminates looseness at the joint between the handle and the rod body, allowing the grip handle to be securely fixed in place relative to the rod body, as well as allowing the handle to be replaced freely.Moreover, it is possible to replace the rod body and tip without using a butt plug. This made it possible to perform extraction.

(Example) Next, an example of the fishing rod of the present invention will be described based on the drawings.

In the figure, 1 is a hollow rod body that is inclined in a tapered shape, and 2 is a handle that is formed to have a diameter larger than the diameter of the base end of the rod body 1 and is connected to the base end, The rod body 1 is formed into a hollow shape by wrapping prepreg, which is formed into a sheet by impregnating a sheet of high-strength fiber such as carbon fiber or glass fiber with a synthetic resin, around a core metal and firing under pressure.
Further, the grip handle 2 is mainly made of wood or synthetic resin.

This idea is based on the fishing rod constructed as described above.
Five to five narrow tapes 3 made of high-strength fibers such as carbon fibers and glass fibers impregnated with synthetic resin are attached to the outer periphery of the joint portion 11 of the rod body 1 with the grip handle 2.
It is wound spirally at intervals of 15 m/m, and is baked under pressure to form a thread 4 that is integrated with the rod body 1, and the grip handle 2 is joined to the joint part 11 by screwing. It was accomplished.

Therefore, the narrow tape 3 is formed into a long and narrow shape by gathering ultra-fine high-strength fibers and impregnating the bundled high-strength fibers with a synthetic resin of the same type as the synthetic resin used in the prepreg for forming the rod body. be.

Further, the thread 4 formed by the narrow tape 3 is formed by winding the narrow tape 3 before the rod body 1 is pressure fired and hardened. After winding the narrow tape 3, cellophane tape is wound spirally around the outside of the narrow tape 3 and bound, and the rod body 1 and the narrow tape 3 are pressurized by this binding, and in this pressurized state, It is heated in a heating furnace, and the synthetic resin in the rod body 1 and narrow tape 3 is cured by this heating, and the synthetic resin in the narrow tape 3 is integrally bonded to the synthetic resin in the rod body 1. Further, the height and pitch of the thread 4 are not particularly limited.

Further, the grip handle 2 is provided with an insertion hole 21 that fits into the joint portion 11 at the center of the distal end thereof, and a screw corresponding to the thread 4 is provided on the inner surface of the insertion hole 21. A groove 22 is provided, and the grip handle 2 is connected to the rod body 1 by screwing the thread groove 22 with the thread 4.

The thread groove 22 may be formed on the handle 2 itself when the handle 2 is formed, but, for example, by applying a release agent to the outer periphery of the joint 11 of the rod body 1,
An adhesive is applied to the outside of this mold release agent layer, and the insertion hole 21 portion of the grip handle 2 is inserted into the outside of the adhesive layer 5, and as the adhesive layer 5 hardens, the adhesive A thread groove is provided on the inner surface of the layer 5 using the thread 4. Then, the adhesive layer is fixed to the inner surface of the insertion hole 21 by curing the adhesive layer.

Note that the thread groove 22 may be formed on the inner surface of the insertion hole 21 by machining or when molding the handle 2 as described above, or may be formed on the handle 2 itself or the difference between the handle 2. Only the insertion hole 21 portion is formed of a soft material, such as wood or synthetic resin, which is softer than the material of the thread 4, that is, the material of the narrow tape 3, so that the joint portion 11 of the grip handle 2 is made of a soft material, such as wood or synthetic resin. When screwing in, the screw thread 4 may scrape off the portion of the soft material that comes in contact with the screw thread to form a thread groove.

In addition, when the thread groove 22 is formed in the insertion hole 21 in advance, adhesive may be used to further increase the strength of the connection between the handle 2 and the rod body 1. The contact resistance between the thread groove 22 and the thread 4 is increased by forming the root diameter smaller than the outer diameter of the thread 4 or by forming the groove width smaller than the thread width of the thread 4. You may also do so.

In addition, the grip handle 2 has a thread groove 22 in advance as described above.
It is not necessary to provide In this case, the insertion hole 2
1 part is formed of a soft material such as cork or rubber, and when the grip handle 2 is screwed into the joint part 11, the thread 4 of the soft material layer is formed by the thread 4.
The contact portion is elastically deformed so that the thread 4 bites into the soft material layer.

The illustrated fishing rod has reinforcing tape 6 having the same structure as the narrow tape 3 wrapped around the other outer circumferential surface of the rod body 1 except for the joint 11.
is reinforced. However, the reinforcing tape 6 is not necessarily required.

In addition, a shock absorber 7 made of rubber or the like is provided in the inner part of the insertion hole 21 of the grip handle 2 to protect the small diameter rod body and the tip that are connected to the tip side of the rod body 1 that is connected to the grip handle 2. ,
When stored in the rod body 1 which is connected to the grip handle 2, the small diameter rod body and tip are received by the buffer body 7.

(Effects of the invention) As described above, the present invention has a structure in which a thread is provided at the joint between the rod body and the handle, and the handle is connected by screwing, so the strength of the joint of the handle is increased. It can be made high, reliably prevent the grip handle from coming off or wobbling against the rod body, and the grip handle can be reliably fixed in a fixed position relative to the rod body.
Furthermore, the grip handle can be freely exchanged with a new grip handle or a grip handle of one's choice.

In addition, a narrow tape made of high-strength fibers impregnated with synthetic resin is used, and when the rod body is formed, this narrow tape is wound spirally at predetermined intervals around the outer circumference of the joint of the rod body. , since the screw thread is formed by being integrally connected to the rod body by pressure firing, the joint part of the rod body can be reinforced by the screw thread,
Not only can the joint be made into a strength-resistant structure, but also a strength-resistant thread can be formed, and damage to this thread can be reliably prevented. The thread can be easily formed by operation.

Furthermore, by removing the handle, you can replace the small diameter rod body and tip that are connected to the tip of the rod body that is connected to the handle, and also drain water that has entered the rod body. Therefore, the conventional butt plug can be eliminated, and the overall structure can be simplified accordingly.
