Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to the structure of a basket attached to ski stocks, and more particularly to the structure of a basket that increases the ability to hold onto the snow surface.

[Conventional technology]

The basket of the ski stock has the function of supporting the ski stock when the ski stock is pushed onto the snow surface, or the function of latching the ski stock to the snow surface. It is also desired that the same function be achieved no matter what angle the ski stock is thrust into the snow surface. Therefore, in the past, a basket with a large diameter was used to increase the area of contact with the snow surface and to stably support the ski poles. Further, as seen in Utility Model Application Publication No. 55-34869, the ski stock 1 is attached to the snow surface by planting the blades facing downward on the outer periphery of a ring-shaped basket and by biting the blades of the basket into the snow surface and latching them. A configuration is known in which it can be latched to. However, with the former, the basket cannot be set to a small diameter, and with the latter, it is not possible to reliably follow the slopes of the ski slopes. Therefore, a configuration can be considered in which a basket with a blade integrally provided on the outer periphery is provided on the ski stock so that it can be tilted, but in this case, as the basket tilts, the angle of entry of the blade into the snow surface also changes gradually, so it is still possible to obtain sufficient latching force. I can't. In addition, in the ski stock ring device of Utility Model Application No. 103174/1974, a configuration is disclosed in which a ring made of plastic or hard rubber is provided with radially extending claws, but in this case as well, claws arranged on the outer circumferential side Since it can be latched onto the snow surface with just the claws, the above-mentioned drawbacks cannot be solved yet.

[Problem that the invention attempts to solve]

This invention was devised as a result of intensive research in view of the above circumstances, and its main purpose is to arrange the locking pawl and the auxiliary pawl in the radial direction so that the basket attached to the ski stock can be set to a small diameter. To provide a basket structure for ski stocks that can follow the snow surface of any slope on a ski slope or the like and can surely exert a latching force.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention has a basket structure for a ski stock equipped with a bucket main body having flexibility and elasticity. b) Forming a locking pawl downward on the outer end side of the basket piece; (c) Forming an auxiliary pawl downward at a position radially aligned with the locking pawl at a midway position on the back side of the basket body. We are taking technical measures such as .

[Effect]

With the above structure, when the basket piece bends upward toward the tip due to contact with a snowy surface such as a steep slope, the auxiliary pawl is displaced downward (in the direction of ground contact) from the locking pawl according to the inclination of the basket piece. However, instead of the locking pawl, it digs into the snow surface of the slope. The flexibility of the basket piece is large on the tip side and small on the proximal side due to the influence of elasticity, so the auxiliary claws provided near the proximal end (midway) prevent the angle of entry into the snow surface from changing much and the basket piece Even if the piece is bent, it can exert a large latching force.

【Example】

A preferred embodiment of this invention will be described below with reference to the drawings. In the basket 1 shown in FIGS. 1 to 3, a basket body 2 is attached to a ski stock 10 via a frame 20. As shown in FIG. That is, the basket body 2 is made of a synthetic resin material having flexibility and elasticity and having a substantially star shape in plan view. The basket body 2 has a hole 3 in the center for fitting the frame 20, and basket pieces 4 extending radially outward from the middle. In this embodiment, the basket pieces 3 are formed so as to be gradually inclined downward toward the outer end and become narrower in width, and five basket pieces 3 are arranged at equal intervals (approximately 72° intervals). The outer end (tip) edge of the basket piece 4 is bent downward to form a locking pawl 5. In the illustrated example, the locking pawl 5 consists of two sharp ends 5a, 5a formed at both sides of the outer edge of the basket piece 4 in the circumferential direction through arcuate notches. Next, the hole 3 formed in the center of the basket body is surrounded by a cylindrical peripheral wall 8 that extends downward from the back surface at the center. Further, on the back surface of the basket body 2, auxiliary claws 6 are provided which are arranged in a radial direction with the basket piece 4. One auxiliary claw 6 is provided at the center of each basket piece 4 in the circumferential direction. This auxiliary claw 6 is formed in a triangular cross section when viewed from the circumferential direction of the basket body, and has a sharp end 6.
a is the sharp end 5a of the locking claw 5 in normal times.
The tip is set upward. An auxiliary rib 7 is connected to the auxiliary claw 6 and is perpendicular thereto. The auxiliary ribs 7 are connected from the cylindrical peripheral wall 8 along the back surface of the basket body 2, and are formed of linear ridges extending halfway along the center line assumed in the axial direction of each basket piece 4. In the case of this embodiment, the cylindrical peripheral wall 8, the auxiliary ribs 7, and the auxiliary claws 6 are molded integrally with the basket body 2 by injection molding. The basket body 2 is attached to the ski pole 10 via a frame 20. The frame body 20 is made of a metal cylinder. The frame body 20 has a groove width corresponding to the width of the cylindrical peripheral wall 8 of the basket body 2 on its outer periphery.
and a fitting groove 2 set to an outer diameter (outer circumferential shape) corresponding to the inner circumferential shape of the hole 3 of the basket main body 2.
1 is formed. Therefore, the frame 20 is inserted into the hole 3 of the basket body 2.
The basket main body 2 and the frame body 20 are connected by fitting and aligning with the fitting groove 21. By fixing this frame 20 to the ski stock 10 by appropriate means, the ski stock 10
A basket is attached to the Next, the operation of the basket structure constructed in this way will be explained. The basket 1 on which the ski stock 10 is pushed up substantially perpendicularly to the snow surface is substantially parallel to the snow surface, and the locking pawl 5 at the lowest end of the basket body 2
The sharp end 5a of the snowboard is bitten into the snow surface and is latched. Next, ski stocking 10 on the steep slope of the ski slope.
When the ski stock 10 is thrust diagonally against the snow surface, as shown in FIG. nothing. As a result, the position of the sharp end 5a of the locking pawl 5 of the basket body 2 rises, and the angle of entry θ' relative to the snow surface decreases in response to the inclination of the tip of the basket, and the locking force weakens. On the other hand, the auxiliary claw 6 provided in the middle of the basket piece has a sharp end 6a relative to the locking claw 5.
When the position of the basket piece 4 is lowered and the deflection of the basket piece 4 exceeds a predetermined angle, it becomes the lowest end instead of the locking claw 5. Furthermore, since this basket piece 4 has elasticity as well as flexibility, the bending angle differs between the distal end and the proximal end, and there is a relative change near the proximal end where the auxiliary claw 6 is provided. Since it is small, there is also little change in the penetration angle θ with respect to the snow surface. Furthermore, since a return force is applied due to the bending, the auxiliary pawl 6 is biased in the direction of snow penetration, increasing the locking force. This effect is further enhanced by the auxiliary ribs 7. In this way, the locking pawl 5 and the auxiliary pawl 6 complement each other in accordance with the angle of the ski stock 10 with respect to the snow surface to exert a predetermined locking force. Next, in this embodiment, the basket body 2 is made of a flexible and elastic synthetic resin material, so if the basket gets caught on an obstacle on the slope, for example, the ski stock 10 can be pulled. If the basket body 2 is tightened, the part of the basket body 2 that is caught on the obstacle will flex, so it can be easily released from the restrained state. After release, it returns to its original state due to elastic restoring force. In this invention, the auxiliary claws 6 may be formed in multiple stages as shown in FIG. Further, the number of basket pieces is not particularly limited, and may be one as long as the basket piece can be bent.

[Effect of the idea]

Since this invention is constructed as described above, no matter what angle the ski stock is pushed onto the snow surface, either the locking pawl or the auxiliary pawl will bite into the snow surface and the ski stock can be reliably latched. Since such a latching force is utilized, it is not necessary to set the shape of the basket body to a large diameter, and it is possible to downsize the basket body. Further, since it can be integrally molded from a synthetic resin material having flexibility and elasticity, it is suitable for mass production and can reduce costs.
