Description

[Detailed explanation of the idea] The present invention relates to a protective cap for ski poles.

When ski poles are not in use, such as when being transported or stored, the tip of the shaft is covered with a cap to protect the tip of the shaft, and to protect the tip of the tip from the human body or other objects. It is preferable to prevent injury or damage to the human body or other objects by colliding with objects.

This cap usually has the following features, as shown in its cross section in Figure 1:
It has a structure with a recess 1 into which the tip of a ski pole is inserted.

However, the cap having such a structure is difficult to attach and detach.

Note that 2 is an air inlet and outlet hole during attachment and detachment.

In other words, in order to make the cap with such a structure easy to attach, it is necessary to make the inner diameter of the recess 1 as large as possible. On the other hand, this cap may accidentally detach from the ski pole, impairing its function and further causing loss of the cap.

If the inner diameter of the four parts is made small to prevent the cap from accidentally detaching from the ski pole, excessive pressure will be required to attach it to the ski pole, and it will also require a large amount of pressure when detached. It requires force and cannot be installed smoothly.

The present invention allows for smooth and easy attachment of the cap to the ski pole, and also prevents the cap from coming off carelessly.
To provide a ski pole cap that allows this to be done smoothly.

An example of the present invention will be described with reference to FIGS. 2 and 3.

FIG. 2 is a perspective view of the cap according to the present invention removed from the ski pole, and FIG. 3 is a sectional view of the cap.

In the figure, reference numeral 11 indicates the ski pole cap according to the present invention as a whole.

Reference numeral 12 denotes the shaft of the ski pole, and the diameter of this shaft decreases toward its tip, that is, it tapers.

Reference numeral 13 indicates a protrusion formed at the tip of the shaft 12.

Further, 14 indicates a basket. In the present invention, the cap body 16 has four parts 15 into which the tip of the shaft 12 of the ski pole having the protrusion 13 is fitted, and the main body 1
A ring part 18 that is formed concentrically with the main body 16 and passes through the tip of the shaft 12 through a connecting piece 17 that extends from a part of the shaft 12, and is elastically fitted to the circumferential surface of the tip; The opening end surface 16a of 16 has a protrusion that protrudes toward the ring portion 18 at a position that maintains an angular spacing of 180 degrees from the other part of the opening end surface 16a, for example, the connecting piece 17, that is, at a position symmetrical to the connecting piece 17 across the axis. The portion 19 is integrally molded as a whole from an elastic body such as synthetic resin or rubber.

The inner diameter of the recess 15 of the cap body 16 is selected in accordance with the outer diameter of the tip of the shaft 12, and is formed to an inner diameter that allows a very light frictional engagement to be achieved relatively easily.

Further, the inner diameter of the ring portion 18 is selected to be such that it can be engaged with the periphery of the distal end portion of the shaft 12 on the larger diameter side than the portion where the cap body 16 is covered with a relatively large frictional force.

Further, this ring portion 18 is connected to the main body 1 via the connecting piece 17.
As shown by arrow a in FIG. 3, this ring portion 18 can be elastically pivoted by the elastic bending of the connecting piece 17.

The height of the protrusion 19 is selected to be approximately the same as the length of the connecting piece 17.

The cap 11 according to the above-described configuration is attached to the shaft 12 of the ski pole by passing the tip of the shaft 12 having the ferrule 13 through the ring portion 18 of the cap 11 and inserting it into the cap body 16.

In this case, the fitting of the ring portion 18 to the tip of the shaft 12 is carried out by the protrusion 19 of the cap body 16 abutting against the ring portion 18. is pressed toward the larger diameter portion of the shaft to a position where it can be smoothly fitted onto the shaft and a large frictional engagement can be achieved.

In this case, the portion of the shaft 12 having the protrusion 13 is protected by the cap body 16, and as described above, the cap body 16 itself is fitted onto the shaft 12 with a frictional resistance that allows for easy attachment and detachment. The ring portion 18 is held in place by a relatively large frictional engagement with the shaft 12.

That is, if the cap body 16 tries to detach inadvertently, this force will pull only one end of the ring part 18 through the connecting piece 17, and the angle between the axis of the shaft 12 and the axis of the ring part 18 will change. A shift occurs and a strong gripping force is generated.

The greater the force with which the cap body 16 separates, the stronger the gripping force of the ring portion 18 becomes, and the more difficult it becomes to separate.

As described above, in the present configuration, the cap body 16
In addition to this, a ring part 18 is provided which mainly engages with the shaft 12, so that the engagement is ensured, and detachment is achieved by lightly pushing the ring part 18 in the detachment direction (the shaft axis and the ring axis are aligned). Furthermore, there are no manufacturing difficulties or differences in cost compared to conventional products, and it can bring great practical benefits.
