Description

[Detailed description of the invention] [Industrial application field] The invention is, for example, capable of expanding and contracting even during the exchange with fish. A mechanism is provided to maintain the state in each of the fitted and retracted states, and the mechanism in the retracted state of the small-diameter rod body is connected to the front and rear ends of the large-diameter rod body and the small-diameter rod body, respectively. The present invention relates to a telescopic original rod structure which is formed by forming a fitting contact portion for tight fitting.

[Conventional technology]

In this type of telescopic original rod structure, in order to form the front-rear fitting contact portion, conventionally, as shown in FIG. The large diameter bulges (1A) and (1B) are formed, and the front bulge (1A) is fitted on the inner peripheral surface of the front end of the large diameter rod (2) while the small diameter rod (1) is retracted. The front and rear bulges (1A) and (1B) so that the rear bulges (1B) are fitted closely to the stoppers (5) located at the rear end of the large-diameter rod (2). Had set the outside diameter.

[Problems to be solved by the invention]

In order to set the retreat state of the small-diameter rod body to a state without "play", the front-rear bulging portion needs to be closely fitted to the corresponding inner peripheral surface of the large-diameter rod body. Requires high centering accuracy to make the small-diameter rod body and the large-diameter rod body concentric, and the outer diameter of the front-rear bulging portion and the corresponding front and rear end inner peripheral surfaces of the large-diameter rod body. The inner diameter dimension had to be strictly controlled, and it was difficult to achieve this due to the balance with manufacturing costs.

Therefore, rattling is likely to occur when the small-diameter rod is retracted, and the handling is not good.

An object of the present invention is to provide a fishing rod with little backlash and good handleability by making a simple modification to the fitting contact portion.

[Means for solving the problem]

The characteristic configuration according to the present invention is to provide an elastic holding member that contacts an outer peripheral surface of the small-diameter rod body on an inner peripheral surface of a front end of the large-diameter rod body that forms the fitting contact portion. In a state in which the fitting contact portion between the small-diameter rod body and the fitting contact portion are tightly fitted, the elastic holding member is in contact with the fitting contact portion and the vicinity of the fitting contact portion of the small-diameter rod body. The effect is as follows.

[Action]

In other words, even if the outer diameter of the outer peripheral surface of the front end portion of the small-diameter rod body is slightly different from the reference dimension, the elastic holder absorbs the difference in the outer diameter size due to its elastic bending, and the outer peripheral surface of the front end portion of the small-diameter rod body is removed. The small diameter rod body is kept in the retracted state by contacting the surface.

[Effect of the invention]

Therefore, strictness is not required as the manufacturing accuracy for the outer peripheral surface of the front end portion of the small diameter rod body. Sticking can be reduced.

However, if the small-diameter rod body is only to be retracted and maintained only in the retracted state of the small-diameter rod body, it is conceivable to provide an elastic retainer on the outer peripheral surface of the front end of the small-diameter rod body. Since the elastic holding member is provided on the inner peripheral surface of the front end of the body, the following effects are also obtained.

Since the elastic retainer also exerts an elastic supporting force on the outer peripheral surface of the intermediate portion of the small-diameter rod body, the expansion and contraction operation of the small-diameter rod body can be performed smoothly without backlash. No hair or fingers are pinched between the front end of the rod and the outer peripheral surface of the small diameter rod body.

Further, since the elastic holding body is provided with a wide range of action so that the elastic holding body comes into contact with the vicinity of the fitting / contacting portion, it is assumed that the fitting / contact state with the fitting / contacting portion in the vicinity thereof is assumed. Even if it is not performed, since the elastic holding action of the elastic holding body extends to the vicinity thereof, even when the fish is hooked and the rod is greatly bent, the elastic holding body is formed on the mating outer surface formed near the fitting close contact portion. Contact can reduce rattling.

〔Example〕

The description will be made based on the structure of the telescoping original rod portion. As shown in FIG. 1, a hand-side original rod (1) as a small-diameter rod body is mounted inside an auxiliary original rod (2) as a large-diameter rod body so as to be able to move back and forth, and after the auxiliary original rod (2). A bottom stopper (4) is attached to the end via a sleeve (3), and a stopper (5) for inserting and fixing the rear end of the proximal rod (1) in the sleeve (3).
To form the original pole part.

A front large-diameter bulge (1A) is provided on the outer peripheral portion of the front end of the proximal rod (1), and the proximal large rod (1) is stored in the auxiliary rod (2). The outer diameter of the front large-diameter bulging portion (1A) is set so that the bulging portion (1A) is fitted and adhered to the inner peripheral surface of the front end of the auxiliary original rod (2). On the other hand, a rear large-diameter bulging portion (1B) is provided on the outer peripheral surface of the rear end of the proximal rod (1). The outer diameter of the rear large-diameter bulging portion (1B) is set so as to be fitted to and adhered to. Therefore, the front large-diameter bulging portion (1A) fits and adheres to the inner peripheral surface of the front end of the auxiliary original rod (1) in a state where the proximal original rod (1) is retracted into the auxiliary original rod (2), Rear large diameter bulge (1
B) is configured to maintain the retracted state of the hand-side original rod (1) by fitting and adhering to the inner peripheral surface of the stopper (5). As described above, the front large-diameter bulging portion (1A) and the inner peripheral surface of the front end of the auxiliary original rod (1) form the front fitting contact portion, and the rear large-diameter bulging portion (1B) and the stopper ( A rear fitting contact portion is formed with the inner peripheral surface of 5).

A flocking (6) as an elastic retainer is planted inward on the inner peripheral surface of the front end of the auxiliary former rod (2), and the flocking (6) is bulged to the front large-diameter bulging portion of the proximal rod (1). Even if the outer diameter of the front large-diameter bulging portion (1A) is slightly different from the reference size by making the front large-diameter bulging portion (1A) elastically contact the inner peripheral surface of the front end of the auxiliary original rod (2). The degree of fitting and close contact between the base rod (1) and the front large-diameter bulging portion (1A) of the base rod (1) can be made to maintain the retracted state of the base rod (1).

The planting area of the flocking (6) is a region including a contact surface forming a fitting contact portion so that, in the retracted state of the hand side original rod (1), a contact action also occurs near the fitting contact portion. It is provided over a wider surface.

When the bristle of the flocking (6) is made longer, an elastic supporting action can be applied also to the front and rear intermediate portion outer peripheral surfaces of the proximal rod (1), and when the proximal rod (1) expands and contracts. This also prevents rattling of the proximal rod (1) and prevents hair and fingers from being pinched between the opening of the front end of the auxiliary rod (2) and the outer peripheral surface of the proximal rod (1).

As shown in FIG. 1 and FIG. 2, when the flocking (6) is planted on the inner peripheral surface of the front end of the auxiliary rod (2), it is planted without protruding from the front end of the auxiliary rod (2). Since there is no attachment of "feed" or "slimy fish" to the flocking (6), the auxiliary original rod (2) and the proximal rod ( It is possible to suppress the change in the fitting state and the change in the operational feeling during expansion and contraction of 1). By attaching an auxiliary ring to the inner peripheral surface of the front end side of the auxiliary original rod (2) further than the area where the hair is implanted (6), it is possible to more effectively prevent the adhesion of "feed".

As described above, the front and rear large-diameter bulging portion (1A) of the proximal rod (1),
(1B) and the inner peripheral surface of the flocking (6) at the front end of the auxiliary rod (2) and the retaining member (5) are referred to as a mechanism for maintaining the retracted state of the proximal rod (1).

As shown in FIG. 2, the rear large-diameter bulging portion (1B) has a slightly larger outer diameter than the front large-diameter bulging portion (1A). In the extended state, the auxiliary original rod (1) is fitted and adhered on the inner peripheral surface at the front end of the front end of the auxiliary rod (1) behind the planted portion (6), and the extended state is fixed and maintained.

With the above configuration, even during the fishing operation, the hand-side original rod (1) can be operated so as to be able to move back and forth, and the length of the original rod portion can be changed to two steps.

[Another Example] The following configuration may be adopted as the mode of planting the flocking (6). As shown in FIG. 3, a tubular member (7) is extended to the front end of the original rod (2), and a bristle (6) is planted on the inner peripheral surface of the tubular member (7). A configuration may be adopted in which the flocking (6) acts on the front large-diameter bulging portion (1A) of the proximal rod (1) with the rod (1) retracted. The auxiliary former rod (2) in this case is a rod body whose inner and outer diameters do not change in the axial direction.

Instead of the flocking (6), an elastically contactable material such as a soft resin or a sponge may be used.
