Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention fits an auxiliary rod body having a grip portion to a base rod so that the auxiliary rod body can be retracted and retracted rearward, and the auxiliary rod can be inserted or retracted in any state. The present invention relates to a telescopic rod provided with a holding mechanism for holding a body against the original rod.

[0002]

2. Description of the Related Art Conventionally, there is a telescopic rod configured as described above as disclosed in Japanese Utility Model Laid-Open No. 3-34770. In this conventional example, the diameter of the original rod is reduced toward the rear end side. When the auxiliary rod body is contracted to the operating end, the outer circumference of the tip of the auxiliary rod is brought into contact with the inner surface of the original rod, and the outer circumference of the rear end of the auxiliary rod is used. When the auxiliary rod body is brought into contact with the inner circumference of the rear end of the base rod, and when the auxiliary rod body is extended to the operating end, the outer periphery of the tip end portion of the auxiliary rod body is brought into contact with the inner periphery of the rear end of the base rod, respectively. It is configured to hold the operation state.

[0003]

As described above, in the rod in which the auxiliary rod body fitted in the original rod is configured to be able to move backward and forward, the rear end of the rod is held by one hand at the time of extension operation, and the other rod is held. Hold the rear end of the auxiliary rod body with your hand and pull it back, then release the hand from the rear end of the original rod and gradually raise the entire rod, so you can change your hand when extending. It has a good surface that you do not have to do it, and during this extension operation, the auxiliary rod body is pulled out backward, and it is not a form to lift the entire rod upward, so even when extending the entire length of the rod Since the phenomenon that the tip of the rod is largely shaken is suppressed without exerting an excessive tension on the fishing line, the fishing line is not likely to be cut off or the fish will not come off. In addition, in the case of fishing in which the decoy ayu is guided by operating the rod, such as the Ayu friend fishing, increasing the total length of the rod during guiding or when pulling out the ayu leads to good rod operation. From the viewpoint of performing this extension operation quickly and without applying excessive tension to the fishing line,
As described above, the effectiveness of the rod in the form of pulling out the auxiliary rod body inserted into the inside of the original rod to the rear is recognized.

However, in the case where the auxiliary rod body is internally fitted to the base rod having a shape that becomes smaller in diameter toward the rear end side, since the rear end of the base rod is likely to be elastically deformed in the bending direction, the condition of the rod is likely to collapse,
In addition, this will lead to the inconvenience that a material having a large diameter cannot be used for the auxiliary rod body. In particular, when a structure for increasing the diameter of the tip portion of the auxiliary rod body is adopted so as to frictionally hold the tip portion and the inner surface of the original rod in the contracted state, when the auxiliary rod body is extended ( During the rearward pulling operation), the large diameter portion is likely to come into contact with the inner surface of the base rod, resulting in an increase in operating resistance, and there is room for improvement. Also, in the case of this type of rod, like the conventional example, when the auxiliary rod body is operated to the end position, the operating state is maintained by the frictional force acting on the contact portion without performing a special operation such as locking. The effective aspect of the operation is also important from the viewpoint of simple operation. The object of the present invention is to make the condition of the part of the original rod good without impairing the good surface of the auxiliary rod body so that it can be pushed back and forth freely, and it is smooth by using the large diameter auxiliary rod body. The point is to configure a telescopic rod that allows the user to perform the withdrawal operation and easily maintain the withdrawal state.

[0005]

As described at the beginning, the feature of the present invention is to provide an auxiliary rod body inwardly retractable with respect to the original rod in any state of the withdrawal and retraction. In the telescopic rod provided with a holding mechanism for holding the original rod, the original rod is formed into a straight cylindrical shape in which the inner diameter on the front end side and the inner diameter on the rear end side are equal, and the holding mechanism is The extension of the auxiliary rod body with respect to the original rod, or at least one of the contraction operation, at the point that it is configured with a contact portion that exerts a frictional resistance to the operation, its action,
And, the effects are as follows.

[0006]

In other words, when the auxiliary rod body is extended, one hand grasps the rear end of the base rod, the other hand grasps the grip portion of the auxiliary rod body, and pulls this grip portion backward. As in the conventional expansion rod, it is not necessary to change hands, and the entire rod is not lifted. With this rod, the original rod is
Since the inner diameter of the tip side and the inner diameter of the rear end side are formed into a straight cylindrical shape, it is possible to increase the bending strength of the rear end side of the original rod as compared with the conventional one, and it is possible to support it compared with the conventional example. It is also possible to use a rod having a large diameter. Moreover,
If the outer diameter of the rear end of the base rod is set to an appropriate outer diameter that is easy to grip and does not carry, the outer diameter of the tip of the base rod, which has a loose conical shape and becomes smaller toward the tip side, becomes smaller than that of the prior art. Therefore, the strength of the tip of the base rod, which will receive the entire load from the top to the tips, may be slightly insufficient, but in the case of the present invention, the outer diameter of the tip of the base rod is Since it can be made the same as the outer diameter of the end portion, it can be made larger in diameter than the outer diameter of the tip portion of the loosely conical base rod whose diameter becomes smaller toward the tip end side, which is advantageous in strength. Further, since the holding mechanism of this rod is provided with a contact portion that exerts frictional resistance, when the auxiliary rod body is operated toward either the operation end (stroke end) of the withdrawal or retraction, the contact is made. When the working area of the portion is reached, the holding state is naturally reached by the frictional force acting on the contact portion, and the holding state is held. During this withdrawal operation, the operation resistance is reduced by eliminating the inconvenience that the tip portion of the auxiliary rod body comes into contact with the inner surface of the base rod and causes an increase in the operation resistance.
It should be noted that, as described above, the phenomenon that the auxiliary rod body naturally reaches the holding state by the frictional force at the end of the retracting operation does not mean that the operation is naturally prevented, and the operation of the auxiliary rod body is prevented by the stopper or the like. It is meant to include those with the structure described. Further, if the frictional resistance value acting on the contact portion at the intermediate position of the retracting operation is made smaller than the frictional resistance value acting on the contact portion of the operation end portion, the reduction of the operation resistance mentioned above becomes more remarkable. To In the case where the core is stored inside the auxiliary rod body, the size of the original rod can be shortened compared to the case where the core and the auxiliary rod body are arranged side by side along the axial direction in the contracted state. Becomes 1 stroke for moving the auxiliary rod
With a setting of less than 00 centimeters, the withdrawal stroke is a length approximately equal to or less than the length corresponding to the distance between the arms of the angler, so that the operation can be performed without holding it. Even when the fisherman holds the rod upright during actual fishing, it is possible to easily operate up to the operation end. If the auxiliary rod body is equipped with a confirmation means for recognizing that the auxiliary rod body has been operated to the operation end, it is possible to easily recognize that the auxiliary rod body has reached the operation end portion. The inconvenience of ending the operation in an insufficient operation state is solved, and at the same time, the inconvenience of causing an excessive operating force to act on the auxiliary rod body and damaging the holding mechanism and the like is eliminated.

[0007]

As a result, the basic rod is made to be in good condition without compromising the good surface of the auxiliary rod body which can be retracted rearward, and the strength of the auxiliary rod body is higher than that of the loose conical rod. It can be deployed advantageously, enabling a light and smooth withdrawal operation using a large-diameter auxiliary rod body, and easily maintaining the rod withdrawal state without performing any special operation such as locking at the operating end. It was possible to construct a telescopic rod that would enable it. Furthermore, with a smaller frictional resistance value at the intermediate position of the operation, a lighter withdrawal operation is possible, and with the one in which the core is stored in the auxiliary rod body, the overall length can be shortened when the entire rod is contracted. If the stroke of the auxiliary rod is set to 100 cm or less, it is possible to move the auxiliary rod in and out with one action, and if the confirmation rod is provided, the auxiliary rod can be moved in and out. The operation of up to the end of the is promoted, and the action of excessive operating force is eliminated.
