Description

  According to the present invention, the flange-side outer fitting surface of the small-diameter casing is fitted to the tip-side inner fitting surface of the large-diameter casing, and the base-side outer fitting surface of the small-diameter casing is fitted to the flange of the large-diameter casing. By fitting to the former-side inner fitting surface, the small-diameter housing is held in a contracted state accommodated in the large-diameter housing, and the outer-side fitting surface of the small-diameter housing is held in the large-diameter housing. The present invention relates to a telescopic scissor that holds the small-diameter housing in an extended state drawn from the large-diameter housing by being fitted to a front-side internal fitting surface.

Originally, as a measure for reducing the feeling of weight and the like as a fishing rod, it is desirable to reduce the diameter of a medium rod or a tip rod as a small-diameter rod. On the other hand, an optimum grip diameter is required for the grip portion of the base rod as a large-diameter frame.
In order to satisfy both of these requirements, as shown in FIG. 5, the heel diameter suddenly expands toward the heel side compared to other parts of the heel 1 at an intermediate position in the heel axis direction of the heel 1. There existed what formed the enlarged diameter part 1B (refer patent document 1).
With such a configuration, it is possible to make the diameter of the middle collar of the original 2 and the like thinner while securing a sufficient grip diameter as the grip portion of the collar 1.

Japanese Patent Laying-Open No. 2004-173682 (paragraph number [0059] and FIG. 8)

By the way, as shown in FIG. 5, in the case where the rapidly expanding portion 1 </ b> B is formed at an intermediate position in the heel axis direction of the main shaft 1, Since it is necessary to fit the heel side outer fitting surface of the heel side outer fitting portion 2B to the heel side inner fitting surface of the heel tip portion 1A of the heel 1, the heel side outer fitting surface of the upper 2 The outer diameter is set to be approximately the same diameter as the inner diameter of the heel side inner fitting surface of the main rod 1.
Then, the large-diameter intermediate portion located on the heel side from the rapidly expanding portion 1B has a larger diameter than the heel side inner fitting surface and the heel side inner fitting surface, while the heel side inner fitting of the base rod 1 is performed. The outer diameter of the base 2 outer fitting surface having the same diameter as the surface and the collar inner fitting surface is smaller than the inner diameter of the large diameter intermediate portion, A large gap is formed between the inner peripheral surface of the portion and the heel side outer fitting surface of the original 2.
In such a relationship between the base 2 and the base 1, when switching the base 2 from the base 1 to the extended state, the base 2 outer end 2 </ b> B of the base 2 suddenly comes out of the restrained state. It will be released. On top of that, the angler added the momentum that the former 2 pulled out with the operating force against the holding force of the former 1 to hold the former 2. A misalignment state may occur, and the heel side outer fitting surface of the heel side outer fitting portion 2B of the upper part 2 may abut on the inner surface of the large-diameter intermediate portion of the heel 1 in an impact manner.
In such a case, an impact sound is generated, and the impact force is transmitted to the hand of the angler holding the base, and the angler may feel uncomfortable.

  The object of the present invention is to suppress the impact of the outer peripheral surface of the outer side fitting portion of the small-diameter housing on the inner surface of the large-diameter intermediate portion of the large-diameter housing during the extension operation of the small-diameter housing. The object is to provide a telescopic rod capable of reducing the uncomfortable feeling of an angler by suppressing the relaxation of force and the generation of impact sound.

〔Constitution〕
A characteristic configuration of the invention according to claim 1 is that the diameter of the large-diameter frame is rapidly expanded toward the base side compared to other parts of the large-diameter frame at an intermediate position in the axial direction of the large-diameter frame. Forming a portion, and the base side outer fitting surface of the small-diameter housing is detached from the base-side inner fitting surface of the large-diameter housing, and the vicinity of the tip side of the base-side internal fitting surface of the large-diameter housing Even if it is in the state located in, it is in the point which is constituted so that the state where the tip side outer fitting surface of the small diameter case may be fitted to the tip side internal fitting surface of the large diameter case is maintained. The operational effects are as follows.

[Action]
A large-diameter housing is provided with a rapidly expanding portion. As a result, the diameter of the grip on the large-diameter frame can be set to a diameter that is easy for the angler to grip, while the diameter of the small-diameter frame such as the original or other medium rods can be reduced, making the lightweight fishing rod less susceptible to weight. Can be maintained.
Even when the small-diameter casing is switched to the extended state while maintaining the shape of the large-diameter casing, the outer-side fitting surface of the small-diameter casing is the base of the large-diameter casing. It is configured to maintain a state in which the tip side outer fitting surface of the small-diameter casing is fitted to the tip side inner fitting surface of the large-diameter casing in a state in which it is located near the side inner fitting surface. Therefore, it is unlikely that the small-diameter housing will cause a large misalignment with respect to the large-diameter housing, avoiding the outer fitting surface of the small-diameter housing from impactingly contacting, and generating an impact sound. And generation | occurrence | production of a vibration can be suppressed.
In other words, even if the base-side outer fitting surface of the small-diameter casing is detached from the base-side internal fitting surface of the large-diameter casing, the tip-side external fitting surface of the small-diameter casing is the large-diameter casing. Since the state in which the body is fitted to the inner side of the flange side of the body is maintained, the small-diameter housing is prevented from being eccentric with respect to the shaft axis of the large-diameter housing. It is possible to avoid the former-side outer fitting surface from impactingly contacting the inner surface of the large-diameter intermediate portion of the large-diameter casing.

〔effect〕
Therefore, an angler with a large-diameter frame can extend and contract the small-diameter frame without feeling uncomfortable.

  The characteristic configuration of the invention according to claim 2 is the invention according to claim 1, wherein the outer diameter fitting surface of the small-diameter housing is detached from the inner fitting surface of the large-diameter housing, so Even if it is in a position near the heel side of the heel side inner fitting surface of the body, a state where the heel side outer fitting surface of the small diameter housing is fitted to the heel side inner fitting surface of the large diameter housing The fitting length along the heel axis direction on the heel-side outer fitting surface of the small-diameter housing that fits the heel-side inner fitting surface of the large-diameter housing is The function and effect are as follows. The fitting length is longer than the fitting length along the axial direction of the outer-side fitting surface of the small-diameter frame fitted to the inner-side fitting surface of the large-diameter frame. It is as follows.

[Function and effect]
That is, when switching to the extended state in which the small-diameter housing is pulled out from the large-diameter housing, the base-side outer fitting surface of the small-diameter housing is detached from the base-side internal fitting surface of the large-diameter housing, Even in the state of being positioned near the heel side of the heel side inner fitting surface of the large diameter housing, the heel side outer fitting surface of the small diameter housing is fitted to the heel side inner fitting surface of the large diameter housing. As the most suitable means for maintaining the state, it is along the heel axis direction on the heel side outer fitting surface of the small diameter hood that fits the heel side inner fitting surface of the large diameter skeleton. Means for setting the fitting length to be longer than the fitting length along the axis direction of the flange-side outer fitting surface of the small-diameter casing fitted to the flange-side inner fitting surface of the large-diameter casing. Presented here.
As a result, the outer-side fitting surface of the small-diameter housing is fitted to the inner-side fitting surface of the large-diameter housing, and the outer-side fitting surface of the small-diameter housing is fitted to the base of the large-diameter housing. Even if the small-diameter housing is pulled out from the contracted state fitted to the side internal fitting surface until the base-side outer fitting surface of the small-diameter housing is detached from the base-side internal fitting surface of the large-diameter housing. Since the tip side outer fitting surface of the small diameter casing maintains the state of fitting to the tip side inner fitting surface of the large diameter casing, the misalignment state of the small diameter casing with respect to the large diameter casing is maintained. It can suppress, and it can avoid that the collar side outer fitting surface of a small diameter housing | casing impact-contacts to the inner surface of the large diameter intermediate part of a large diameter housing.
Therefore, an angler with a large-diameter frame can extend and contract the small-diameter frame without feeling uncomfortable.

Even if the original-side outer fitting portion 2B is inserted in a state where it is in contact with the inclined surface 3c due to the misalignment, it is possible to adopt a configuration that smoothly guides to the insertion hole 3B. An internal thread 3d is formed on the flange side of the insertion hole 3B of the insertion hole 3B in the elastic holder 3 so that the bottom plug 5 is screwed.
As a material used for the elastic holding body 3, thermoplastic resins such as ABS and Duracon, nitrile rubber, chloroprene rubber, and the like can be used, and soft resins and the like can be used. A lining material such as nitrile rubber or chloroprene rubber made of a material different from that of the elastic holding body 3 may be applied to the surface portion of the inclined surface 3c of the elastic holding body 3, or the elastic holding member may be mounted by spraying the surface. Further, an elastic force may be imparted to the surface.
On the other hand, the inner peripheral surface of the heel tip portion 1A of the base rod 1 is referred to as a heel side inner fitting surface 1a.

  With the above configuration, as shown in FIG. 2, by fitting the heel side outer fitting surface 2 b of the base 2 to the heel side internal fitting surface 1 a of the base 1, 1 is held in an extended state.
