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 does not need to be done, and the auxiliary rod body is pulled out backward at the time of this extension operation, so it does not lift the entire rod upward, so even when increasing the total length of the rod It does not apply excessive tension to the fishing line, and since the phenomenon that the rod tip swings greatly is also suppressed, cutting the fishing line,
Alternatively, it also has a good aspect that it is difficult for fish to 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. This extension operation is quick and
From the viewpoint of performing the fishing line without applying an excessive tension, 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 as described above 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 leads to the disadvantage that a material having a large diameter is not 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, with this type of rod, like the conventional example,
Even when the auxiliary rod body is operated to the end position, the frictional force acting on the contact portion without performing a special operation such as locking is effective in that the operation state is maintained from the viewpoint of performing a simple operation. Has become important. 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 gently sloping tubular shape whose diameter is reduced toward the tip end side, or a straight tubular shape, and the holding mechanism is provided. , At least a contact portion for maintaining a relative positional relationship between the original rod and the auxiliary rod body by causing a frictional resistance to act on the auxiliary rod body in a state where the auxiliary rod body is set to any one of the protruding and retracting end portions , Operates with the auxiliary rod body (3) set to the retracted end
The holding mechanism (A) is arranged in the radial direction of the base rod (2).
A protruding portion (11a) protruding toward one side, and this protruding portion
It is recessed from the part (11a) to the outside in the radial direction over the entire circumference.
The outer peripheral surface (11b) formed with
1) and the entire circumference toward the outside in the radial direction of the base rod (2).
Protruding surface (13a), and this protruding surface (13a
a) A circle that is recessed inward from the inside in the radial direction.
A surface (13b) is formed and engages with the engaging outside (11)
And the inside of the engaging (13)
And, the effects are as follows.

[0006]

When the above-mentioned features are configured as shown in FIGS. 1 to 3, for example, when the auxiliary rod body 3 is extended, one hand holds the rear end of the base rod 2 and the other hand holds the auxiliary rod body. Hand grip 3
Grasp the grip and pull the grip part 5 backwards.
You do not have to change hands like the conventional expansion rod,
Also, the whole rod is not lifted. Also, with this rod, the diameter of the base rod 2 is reduced toward the tip end side (increased toward the rear end side) .
Since it is formed in a tubular shape, it is possible to increase the bending strength on the rear end side of the base rod 2 as compared with the conventional example, and use an auxiliary rod body 3 having a larger diameter than that of the conventional example. Will also be possible. Further, in this rod, since the holding mechanism A is provided with a contact portion that exerts frictional resistance, when the auxiliary rod body 3 is operated to either the operation end (stroke end) of the withdrawal or retraction, the contact is made. The holding state is naturally reached by the frictional force acting on the part, and the state is held. Further, at the time of this withdrawal operation, it is possible to eliminate the inconvenience that the tip portion of the auxiliary rod body 3 comes into contact with the inner surface of the base rod 2 and causes an increase in the operating resistance, thereby lowering the operating resistance. It should be noted that the phenomenon that the auxiliary rod body 3 naturally reaches the holding state by the frictional force at the end of the withdrawal operation as described above does not mean that the operation is naturally prevented, and the operation of the auxiliary rod body 3 by the stopper or the like. It also means that the structure is blocked.

Further, if the value of the frictional resistance acting on the contact portion at the intermediate position of the retracting operation is made smaller than the value of the frictional resistance acting on the contact portion at the operation end, the above-mentioned reduction of the operating resistance is further improved. Make it remarkable. In addition, in the case where the core 14 is housed inside the auxiliary rod body 3, as compared with the case where the core 14 and the auxiliary rod body 3 are arranged side by side along the axial direction in a contracted state, It is possible to shorten the dimension of.
In addition, when the stroke of the auxiliary rod body 3 is set to 100 cm or less, the fisherman can easily operate up to the operation end even when the fisherman stands up the rod during actual fishing.
Further, in the case where the confirmation means C for recognizing that the auxiliary rod body 3 has been operated to the operation end portion is provided, since it can be easily recognized by the confirmation means that the auxiliary rod body 3 has reached the operation end portion, At the same time, the inconvenience of ending the operation of the rod body 3 in an insufficient state of the withdrawal operation is solved, and at the same time, an excessive operating force is applied to the auxiliary rod body 3 to damage the holding mechanism A and the like. It will be resolved.

[0008]

Therefore, without damaging the good surface of the auxiliary rod body that can be retracted rearward, the tone of the part of the original rod is made good and the auxiliary rod body of large diameter is used to lighten the condition. It was possible to construct a telescopic rod that enables a smooth withdrawal operation and that allows the operation end to be easily maintained without the need for a special operation such as locking. 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.
