Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to ski poles.

[0002]

2. Description of the Related Art Conventionally, ski skis are shown in FIGS.
Was configured as shown in. That is, in FIG.
Reference numeral 1 is a rod-shaped pole that constitutes a stock, and a cylindrical stopper 22 is fixed to the lower portion of the pole. And Paul 2
A ring 23 having an insertion hole at the center was fitted from the lower end of 1, and a washer 24 (see FIG. 5) was further fitted, and the stopper 23 and the washer 24 sandwiched and fixed the ring 23. As a result, the pole 21 located below the ring 23 becomes the stone projection 25. In addition, washer 2
The inner edge of 4 has a plurality of locking pieces 24s protruding toward the center.
, And the locking pieces 24s are pressed against the peripheral surface of the pole 21.

[0003]

However, the conventional ski poles have the following drawbacks.

First, since the metal washer 24 is fitted from the lower end of the pole 21, the surface of the pole 21 is scratched by the locking pieces 24s that are pressed against the pole 21.
Product quality is greatly reduced, such as deterioration in quality.

Secondly, with respect to the pole 21, the stopper 2
2. Since it is necessary to assemble the ring 23 and the washer 24, the number of parts, the assembly process (man-hour), and the manufacturing cost are increased.

Thirdly, when it is used severely, the washer 24 is loosened and the ring 23 is loosened, and the ring 2 is loosened.
There is a risk that 3 will fall out.

The present invention solves the problems existing in the prior art as described above, and it is possible to improve the quality and merchantability, reduce the manufacturing cost, and eliminate the adverse effects such as loosening and dropping of the ring. The purpose is to provide ski skis.

[0008]

According to the present invention, when a ski pole 1 is provided with a stone protrusion on the lower part of a pole and a ring portion is provided on the upper end of the stone protrusion, particularly, the stone protrusion 3 and the ring portion are used. 4 is integrally formed of synthetic resin, the projection 3 is formed as an internal hollow with at least the upper end opened, and the lower portion of the pole 2 is inserted and fixed inside the projection 3. In addition, it is preferable that the lower end of the stone protrusion 3 be opened and closed by a metal cap body 5.

[0009]

According to the ski pole 1 of the present invention, the stone protrusion 3 and the ring portion 4 are integrally formed of synthetic resin, and the lower portion of the pole 2 is inserted into the stone protrusion 3 from the upper end and fixed. Assemble. Therefore, the ring portion 4
No need for stoppers and washers to secure the pole 2
The number of parts to be provided in the lower part is only one-third of that of the conventional product, since only an integrally molded product made of synthetic resin is sufficient. Further, the ring portion 4 is a stone projection portion 3 fixed to the lower portion of the pole 2.
As a result, the adverse effects such as looseness and falling of the ring portion 4 are eliminated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

First, a ski pole 1 according to the present invention comprises a unit portion 10 in which a ridge portion 3 and a ring portion 4 are integrally molded of synthetic resin. In this case, the ring portion 4 is formed in a disk shape, and a pipe-shaped stone protrusion 3 that is perpendicular to the center of the ring portion 4, that is, an internally hollow stone protrusion 3 having an open upper end and a lower end is provided.

The ring portion 4 is formed with a thick portion 4s along the circumferential direction on the periphery thereof, and four rib portions 11 ... Which are integrally formed on the lower surface of the ring portion 4 at equal intervals in the circumferential direction are integrally formed. Form. One rib portion 11 is formed to be elongated from the center in the radial direction, and the protruding width gradually increases toward the center.

On the other hand, the stone projection 3 is provided such that the upper portion thereof projects slightly above the upper surface of the ring portion 4, and the stone projection portion 3 located below the ring portion 4 has its lower half portion on the lower side. The diameter is gradually reduced, and a metal cap body 5 is fitted and closed in the opening at the lower end.

On the other hand, 2 is a pole, which is formed in a hollow inside and gradually becomes smaller in diameter toward the front end side (lower end side) (see FIG. 3). Since the pole 2 is processed by being narrowed down at the time of molding, the wall thickness becomes larger on the smaller diameter side. Further, carbon graphite is used as the molding material of the pole 2. Carbon graphite is 93-99 weight percent, preferably 96
Weight percent carbon and 1 to 7 weight percent,
It preferably contains 4 weight percent graphite, which is glass fiber. With such a component mixture ratio, not only light weight, but also appropriate elasticity can be obtained, and shock absorption and durability can be enhanced, and in particular, temperature resistance can be enhanced.
Even at low temperatures, the impact absorption and the durability are prevented from decreasing. Therefore, it can be used as a molding material most suitable for the pole, because it can be used at a low temperature and can sufficiently satisfy the performance factors required for the pole to be frequently impacted in the longitudinal direction during use.

Then, as shown in FIG.
The lower portion of the pole 2 is inserted into the inside through the opening at the upper end of the stone protrusion 3 at 0, and both are fixed by using an adhesive or the like. A grip portion 15 is attached to the upper end of the pole 2 as shown in FIG. Thus, the stock 1 can be assembled very easily. Since the stock 1 is configured in this manner, the color of the stone protrusion 3 can be easily changed with respect to the color of the pole 2, and the strength (protection) of the stone protrusion 3 can be increased.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment,
The detailed configuration, shape, and the like can be arbitrarily changed without departing from the scope of the present invention.

[0017]

As described above, in the stock according to the present invention, the stone projection and the ring portion are integrally molded by the synthetic resin, and the stone projection is formed in the inner hollow with at least the upper end opened, and the pole of the pole is provided inside the stone projection. Since the lower part is inserted and fixed, the following remarkable effects are obtained.

Since a stopper and a washer for fixing the ring portion are not required, it is possible to eliminate the adverse effects such as scratches on the surface of the pole at the time of assembly, and to improve quality and commercialability.

Since the parts provided under the poles may be integrally molded products made of synthetic resin, the number of parts can be reduced to 1/3 of the conventional one, and the assembly process (man-hours) and the manufacturing cost can be significantly reduced.

Since the ring portion is integrated with the stone projection portion fixed to the lower portion of the pole, the adverse effects such as loosening and falling off of the ring portion due to severe use are eliminated.
