Description

[Detailed explanation of the invention] Conventionally, this kind of ski pole not only does not have smooth bending (falling action) when touched by an athlete, but also has a complicated structure and a large number of parts, resulting in poor productivity. There was a problem with the cost reduction being limited.

The present invention relates to a ski pole (flag) mainly used for slalom competitions that eliminates such defects, and has a screw 1 on the outer surface and a spring and a rubber string inside the pipe 2 for sending it into the snow. A mooring member 4 such as a chain or a wire is connected or not connected to the upper end of the telescopic member 3, and the telescopic member 3 is
A hard plastic lip member 7 is fitted to the upper end of the stud pipe 2 by means of a pin 6 or the like to a stone protrusion 5 whose lower end is fitted to the lower end of the stud pipe 2, and the outer periphery of the upper surface of this lip member 7 is fitted. A short tubular wall 8 with a rounded upper edge is integrally provided, and separately from this, a short tubular undulating main member 10 is made of hard plastic and integrally has an outward flange 9 in the middle. 10, a protruding strip 11 with a round instep is provided in a headband shape at a location slightly below the outward flange 9, and a U-shaped concave strip 12 is formed between the protruding strip 11 with a round instep and the outward flange 9. At the same time, the portion 13 below the outward flange 9 of the undulating main portion 10 is invaginated into the short tubular wall 8, and the outward flange 9 is mounted on the short tubular wall 8. Strongly pull the upper end of the mooring member 4 through the inner diameter hole 14 to remove the telescopic member 3.
The upper part of the mooring member 4 is secured to the upper part of the undulating main part 10 with a pin 15 or the like in a state in which a suitable tension is obtained, and then a pole is attached to the upper end 16 of the undulating main part 10 and a delivery pipe 17 or the like is connected to the upper part of the undulating main part 10. The gist of this is that the connection is made through the link.

The illustrated embodiment is a thermoplastic hard plastic string body 2 having a triangular cross section on the outer periphery of a hard plastic round pipe 21 obtained by extrusion molding.
2 is softened by heat, wound spirally, and then rehardened by cooling, and the contact surfaces of the string-like body 22 and the round pipe 21 are joined with an adhesive in the same manner as brazing, thereby making the outer part. A spring 3 is inserted into the snow by connecting a chain 4 to the upper end of the spring 3, and the lower end of the spring 3 is inserted into the snow. A pin 6 is used to lock the stone protrusion 5 fitted into the lower part of the vertical pipe 2, and a hard plastic rim member 7 is fitted to the upper end of the vertical pipe 2. A short tubular wall 8 with a rounded edge is integrally provided, and separately from this, an outward flange 9 made of hard plastic is integrally formed in the middle, and a reinforcing metal pipe 10' is inserted inside. The undulating main part 10 is formed, and in the undulating main part 10, a protruding strip 11 of a round instep is provided in a headband shape at a location slightly below the outward flange 9, and these protruding strips 11 of the instep and the outward flange are formed. U-shaped grooved line 12 between
At the same time, the portion 13 below the outward flange 9 of the undulating main portion 10 is invaginated into the short tubular wall 8, and the outward flange 9 is mounted on the short tubular wall 8. The upper end of the chain 4 is strongly pulled through the inner diameter hole 14 of the telescopic member 3 to obtain an appropriate tension, and the upper part of the chain 4 is locked to the upper part of the undulating main part 10 with the pin 15 (in this case, , use the upper ring 23 of chain 4 as a hook when pulling strongly as described above, and then tighten pin 1.
5 can be easily inserted. ) Further, a pole is connected to the upper end portion 16 of the undulating main portion 10 via a stud pipe 17, a fixing screw 18, etc.

Further, in the figure, 25 indicates a decorative cover made of an elastic and flexible material that also serves to prevent danger, and 26 indicates a wall to prevent the cover 25 from slipping off.

Since the present invention has the above-mentioned configuration, it is of course effective in eliminating the various defects mentioned above, but it is particularly effective in eliminating short-circuited problems even when the device falls to a nearly right angle, as shown by the imaginary line in Figure 3. The fitting between the instep round edge of the tubular wall 8 and the concave strip 12 may become disengaged, resulting in an unsightly condition, or an unnatural movement such as a so-called jerking or jerking may occur, or restoration to the upright state may not be possible. It has excellent effects such as not causing any irritation or the like.

In the present invention, a rubber string or the like may be used instead of a spring, and a wire or the like may be used instead of a chain.
