BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod with a length adjusting mechanism. Therefore, the first middle rod and the second
The middle rod, fishing rods and the fishing operation can be performed by accommodating and holding the respective Motosaonai, or push by interpolation from the rear end of the original rod of Tsugizao, and or drawers, make adjustments of its length fraction The present invention can be used for a so-called spliced fishing rod with an auxiliary rod tube, and may be a fishing rod in which such an auxiliary rod tube is inserted at the rear end of a single rod.

[0002]

2. Description of the Related Art When using ayu rods or mountain stream rods, it is sometimes necessary to adjust the length of a fishing rod. Japanese Patent Application Laid-Open No. 6-225666 discloses a mechanism for adjusting the length of an original rod by pulling out or storing an auxiliary rod tube inserted behind the original rod. In this publication, a circumferential surface portion that is recessed over the entire circumference is formed on the engaging outer portion 11 of the original rod as a confirmation means that allows the operator to recognize the completion of the operation up to the operation end of the auxiliary rod body. ,
A projecting ridge projecting over the entire circumference is formed in the engagement interior 13 of the auxiliary pole body, and when this circumferential surface portion and the projecting ridge are fitted,
It is disclosed that the vehicle can be overcome while being elastically deformed.

[0003]

On the contrary, when the fitting state is to be released, a strong resistance is applied, and when a strong force is applied, it is released suddenly, causing a shock, and smooth operation cannot be performed. If this is done while fishing, the surplus force at the moment of release will cause a large shock in the axial direction, resulting in a strong swing of the tip of the rod or vibration of the fishing rod. In particular, when the fish is caught, the fish may escape or the thread may break.

Accordingly, an object of the present invention is to provide a fishing rod with a length adjusting mechanism which has a sense of moderation when the length is adjusted and does not give a shock to the fishing rod when the engaged state is released.

[0005]

SUMMARY OF THE INVENTION In view of the above objects, the present invention is directed to a fishing rod with a length adjusting mechanism used by joining two or more rod pipes , wherein the first rod is a first rod, 2nd
A regulating portion for regulating a movement end position in the axial direction when the rod or the auxiliary rod tube is stored, and an elastic engagement provided at a rear end of the original rod and the engaging body being urged by an elastic body. Engage with the mechanism at the position of the axial direction regulation by the regulation section
A hole or groove provided in the accommodated rod tube so as to be able to rotate, and by rotating one of the rods in the circumferential direction, the engaging body engages with the hole or groove so that the rotational operation resistance sharply increases. A fishing rod with a length adjusting mechanism, wherein the engagement can be released by further rotating the one in the same direction or the opposite direction. The rotation here means not only rotating in the circumferential direction but also forming a guide between the other and the other, for example, by moving one of the guides in the axial direction before the regulating position. This includes the case where the robot is automatically rotated in the circumferential direction along with the movement in the long direction.

[0006]

In the storage operation state, the end of the movement in the storage direction is determined by the restricting portion in the movement in the axial direction in the operation of storing, and if the rotation operation is performed at this restriction position, the rotation resistance suddenly increases at a predetermined angular position and the other is engaged. Therefore, the engagement is recognized by the sense of the hand, and there is a sense of moderation of the engagement. In addition, release can be similarly performed by turning, and there is a sudden change in operation resistance, but since it is a turning operation, the change can be absorbed by the wrist, and it is possible to prevent shock from being applied to the fishing rod, and to perform smooth operation Can be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 shows an embodiment of a joint type fishing rod with a length adjusting mechanism according to the present invention. A high-strength fiber such as carbon is impregnated with a thermosetting resin such as an epoxy resin, or a fiber-reinforced prepreg mixed with a thermoplastic resin such as a polyamide is wound and fired to form a former rod 10, which is joined to the former rod, A first inner rod 12 similarly formed is shown.
The second and subsequent middle poles are omitted. A rod end part 15 is screwed to the rear end of the original rod 10, and a support 16 of an elastic engagement mechanism 18 is attached inside the rod end part 15. The elastic engagement mechanism 18 is formed at a position a predetermined distance in front of the shoulder 16K of the support 16 and is disposed in two cylindrical holes 16H separated by 180 degrees (located on opposite sides). It has a steel ball 20 as an engagement body and a coil spring 19, and is configured not to fall from the hole 16H and to be able to advance and retreat in the hole depth direction. Further, the coil spring 19 pushes the top of the steel ball 20 out of the hole 16H by the normal urging force.

On the other hand, a rod end part 22 for a middle rod is attached to the rear end of the first middle rod 12, and an inclined chamfer is provided at the rear end of the part 22 so that the steel ball 20 can ride easily. 22C, and the steel ball 20C is formed by the chamfer 22C.
Can be pressed smoothly into the hole 18H. This chamfer 22C may be curved. In addition, holes 22H forming a part of an elastic engagement mechanism capable of locking the steel ball 20 at a position forward of a predetermined distance from the rear end face 22K are formed at two places separated by 180 degrees. The hole wall, that is, the component 22 is formed of a material such as synthetic resin having good slipperiness such as Duracon (trade name) to prevent the steel ball 20 from being damaged by the rotation of the steel ball 20. The steel ball 20 is made of metal,
It may be made of ceramics, and is preferably made of a material different from the material of the component 22 on the receiving portion side.

In this manner, the first inner rod 12 can be stored until the rear end face 22K of the component 22 comes into contact with the shoulder 16K, and the storage is restricted at this position, and the shoulder 16K and the rear end face 22K constitute a restricting portion. ing. Generally, the hole 22H and the steel ball 20 do not face each other at the storage restricted position,
Is pressed against the inner surface 22S of the component 22 and is in a point contact state. Therefore, if the first middle rod 12 is relatively rotated with respect to the original rod 10 in any direction, the first middle rod 12 is lightly rotated (if the steel ball 20 is rotatably received by the coil spring 19, the rolling friction state). ) At a predetermined angular position, the steel ball 20 is pushed out and engaged at the position of the hole 22H by the action of the coil spring 19. Therefore, after that, even if the first middle rod 12 is rotated, the rotation resistance suddenly increases, and the operator can recognize that this is the engagement point.

At the time of such a storing operation, the rear hand grips the rear portion of the former pole 10 and the front hand grips the vicinity of the front end of the first middle pole 12. In order to engage the hole 22H and the engaging body 20 of the elastic engagement mechanism 18 only by moving backward in the original rod, the hole 22H is formed to be longer in the circumferential direction, and the front end surface of the original rod and the first middle rod are formed. 12, a matching mark or the like is formed on the front surface, and stored together with the matching mark, or a guide is formed inside the original rod. In this embodiment, when the first middle rod 12 is stored, the protruding portion 12K on the front outer peripheral surface of the first middle rod 12 is connected to the joint inner surface 10K of the original rod 10.
Lightly contact with the rod to prevent rattling of the fishing rod operation after storage. With the first middle rod 12 housed in the former rod 10 in this manner, the steel ball 20 and the hole 22H are engaged and the fishing rod is short and spliced, so that the fishing operation can be stably performed. .

To release this state and return to the original state, the rear hand grips the rear part of the original rod 10, and the front hand grips the vicinity of the front end of the first middle rod 12. If a predetermined force is applied in any direction to cause relative rotation, one of the engagements is a sphere, so that the steel ball 20 can be pushed down by the inner surface 22S of the component 22 to get over the hole 22H. If the steel ball 20 gets over the hole 22H in this way, then the steel ball 2
Contact resistance between 0 and the inner surface 22S of the component 22 (rolling resistance)
Therefore, even if the first middle rod 12 and the former rod 10 are relatively moved back and forth, no shock is generated, and the pull-out operation can be performed smoothly. In this initial rotation operation, a predetermined force is applied, and when the steel ball 20 comes out of the hole 22H, the operation resistance is rapidly reduced. However, since the direction of this force is the rotation direction, the shock is absorbed by the wrist. Therefore, the fishing rod does not need to be shocked. Therefore, even if a pull-out operation is performed after such a rotation operation during fishing, it is possible to prevent the rod tip from being shaken or the hooked fish from being released.

[0012] In the above embodiment, the steel balls 20 are configured to engage the hole 22H of the part 22, the hole 22H may be a groove, also, although outside the scope the present invention, the coil spring 19 And the steel ball 20 may be provided on the inner surface side of the component 22, and holes and grooves may be formed on the outer peripheral side of the support 16. However, it is preferable to arrange a steel ball or the like in a direction where there is room in the radial space. Further, the regulating portion may be constituted by the bottom surface of the component 22 and the top portion of the support 16.

Further, such a structure is adopted at the rear end of the former pole.
As an alternative form outside the scope of the invention, it may be adopted at the front part of the original rod. For example, the first middle rod 12 is pulled out and spliced to the tip joint portion of the original rod 10 to be stored during use. Even if it is desired to shorten the fishing rod, it is preferable to adopt the structure of the present invention at this end joint portion so as not to give a shock to the fishing rod by the operation. Further, it may be employed not only between the former rod 10 and the first middle rod 12 but also between the former rod and the first and second middle rods as shown in FIG .
Ku, other, may be employed between the base rod and the auxiliary rod pipe.

FIG. 2 shows an example of a structure in which the first middle rod 12 and the second middle rod 14 can be housed and engaged together in the former rod 10. FIG. 3A is an enlarged view of the elastic engagement mechanism 18, in which a coil spring 19 and a steel ball 20 are put in a cylindrical body 18C, and the steel ball 20 is formed by a flange on the upper part of the cylindrical body 18C. The stopper is formed. (B) is a hemispherical or semi-elliptical body 20 'instead of the steel ball 20 of (a).
Are shown in FIG. Due to such a shape, a force is applied in the circumferential direction so that the engagement bodies 20 and 20 ′ are formed.
Can be disengaged from the hole or groove of the rod tube or part, and can be moved both in the circumferential direction and in the axial direction.

FIGS. 4A and 4B show a structure in which the engagement members 20, 20 'are urged by an elastic member 19' such as a rubber member instead of the coil spring 19 of FIG. The inside of the engaging body 20 'of (b) is formed by an elastic body, but the surface is configured by covering or coating a hard hemispherical shell formed of metal, ceramics, or the like.

[0016]

As is apparent from the above description, according to the present invention, in the storage operation state , the end of the movement in the axial direction in the axial direction is determined by the restricting portion. Since the rotational resistance suddenly increases at a predetermined angular position and engages with the other, the engagement can be recognized by the sense of the hand, and there is a sense of moderation of the engagement and the user can feel safe. In addition, release can be similarly performed by rotating, and when released, the operation resistance decreases rapidly, but due to the rotation operation, the change can be absorbed by the wrist, and it is possible to prevent the fishing rod from being shocked, and to smooth out Can operate.
