CROSS-REFERENCE TO RELATED APPLICATIONS

This Patent Application claims priority from Italian Patent Application No. 102021000004742 filed on March 1, 2021 .

TECHNICAL SECTOR

This invention relates to an adaptable ski pole, in particular a ski or ski mountaineering pole having a basket that can be adjusted depending on an uphill or downhill use condition.

PRIOR ART

Poles are known, commonly known as "ski poles" or "ski mountaineering poles" or "hiking poles", that are used by professional athletes, amateur skiers or hikers.
The poles are a type of sports equipment that are used in pairs, which may have, depending on the environment and sports activity for which they are used:

the function of stabilising the skier when descending a snowy slope;
the function of propelling the skier, for example in cross-country skiing;
the function of balancing the hiker or ski mountaineer or during a hike on foot across the snow.

A pole of the type described above essentially comprises a tubular rod having a longitudinal axis and constitutes the actual pole, a handle grip fixed to a first axial end of the rod, and a tip arranged at a second axial end of the rod opposite the first.
Typically, the tip is surrounded by a ring nut, which is fixed at a certain distance from the tip itself and is commonly known as a "basket"; it has the function of preventing the tip from sinking too deeply in the snow and, at the same time, of stabilising the user during the sports activity.
In the sector, specific poles are known for different types of winter sport.
In particular, different types of baskets are known: poles used in downhill skiing typically have a basket with small dimensions, so as to stabilise the skier, while avoiding, at the same time, the pole from sticking too deeply in the snow; the ski mountaineering poles, in contrast, comprise a larger basket, so as to support the weight of the skier, avoiding the pole's sinking into the fresh snow.
During ski mountaineering, the ski mountaineer first ascends the slope with the aid of skis and synthetic skins arranged on the lower surface of the skis, after which they descend the slope in fresh snow using skis.
For the uphill and downhill steps, it would be useful to have different types of baskets, but today the only way to have different baskets is to replace them on each pole.
This replacement operation is, however, often complicated due to the gloves that the user wears, the intense cold, and the wear of the baskets themselves. In addition, there is the chance that the replacement baskets may be lost.

SUBJECT AND SUMMARY OF THE INVENTION

The purpose of this invention is to obtain a ski pole which is highly reliable and inexpensive, and makes it possible to avoid the drawbacks specified above and connected to known ski poles.
According to the invention, this purpose is achieved with a ski pole as claimed in claim 1.

BRIEF DESCRIPTION OF THE DRAWINGS

To better understand this invention, a preferred, but non-limiting, embodiment is described below, by way of example, and with the aid of the attached figures in which:

Figure 1 is a side view, with parts removed for clarity, of a ski pole produced according to this invention;
Figure 2 is a perspective, exploded view, on an enlarged scale and with parts removed for clarity, of the lower end of the pole in Figure 1; and
Figures 3 and 4 illustrate, in side view, and with parts removed for clarity, the pole in Figure 1 during two different operating conditions.

DETAILED DESCRIPTION

With reference to Figure 1, the reference number 1 indicates, as a whole, a ski pole.
The pole 1 is suitable for being used in a pair with another, identical pole 1 (not illustrated) during sports activities such as downhill skiing, ski mountaineering, cross-country skiing or hiking, in particular hiking on the snow, in order to assist the user during the activity itself.
In particular, the pole 1 is designed to support, balance, and/or stabilise the user during the sports activity.
As can be seen in Figure 1, the pole 1 essentially comprises:

a tubular rod 2 having a longitudinal axis A, which is preferably straight;
a handle grip 3 arranged at a first axial end 4 of the rod 2;
a tip 5 arranged at a second axial end 6 of the rod 2 axially opposite to the first end 4; and
a basket 7 transverse to the axis A, arranged in a position axially near the tip 5, i.e., arranged at the second end 6.

In particular, the basket 7 extends along a plane transverse to the axis A. More specifically, the basket 7 extends along a plane orthogonal to the axis A, i.e., it is basically orthogonal to the axis A and, thus, to the rod 2.
According to one embodiment not illustrated, the rod 2 could comprise, as is known, shaped sections, which are not straight, but oblique or inclined, or be a telescopic pole composed of several parts, though preserving its essential extension along the axis A.
As can be seen, in particular, in Figure 2, the basket 7 comprises a first element 8 firmly fixed to the rod 2 (or, alternatively, to the tip 5), in particular fixed firmly to the rod 2, and a second element 10 that is movable relative to the first element 8 and configured to define, in use, a support surface in relation to the snow-covered terrain on which the user practises their sport.
In other words, the second element 10 defines that essential part of the basket 7 configured to balance, support, and/or stabilise the user during the sports activity.
According to the non-limiting example described and illustrated here, the first element 8 and the second element 10 are defined by respective shaped ring nuts that are transverse, in particular basically orthogonal, to the axis A.
The first element 8 has a perimeter edge 11, which includes a first edge portion 12 and a second edge portion 13 opposite to one another with respect to the tip 5.
Similarly, the second element 10 has a supporting edge 14 and a leading edge 15 opposite to one another with respect to the tip 5.
Specifically, as can be seen in Figures 3 and 4, the first edge portion 12 and the second edge portion 13 are spaced apart from one another along a direction that is transverse, in particular basically orthogonal, to the axis A.
More specifically, the transverse direction defines, in use, a direction of travel D of the user during the sports activity.
According to the example described, the first edge portion 12 faces, in use, towards the direction of travel D. Thus, in use, the first edge portion 12 defines a front portion of the first element 8 while the second edge portion 13, which is opposite the first edge portion 12 in relation to the tip 5 and is spaced apart from the first edge portion 12 along the direction D, defines a back portion of the first element 8.
Similarly, the supporting edge 14 and the leading edge 15 are spaced apart from one another along said direction that is transverse, in particular basically orthogonal, to the axis A.
In addition, the leading edge 15 faces, in use, towards the direction of travel D. Thus, in use, the leading edge 15 defines a front edge of the second element 10 while the supporting edge 14, which is opposite the leading edge 15 in relation to the tip 5 and is spaced apart from the leading edge 15 along the direction D, defines a rear edge of the second element 10.
According to the invention, the second element 10 is movable relative to the first element 8 between:

a first position, in which the first edge portion 12 is at a first distance d1 from the supporting edge 14 (Figure 3); and
a second position, in which the first edge portion 12 is at a second distance d2 from the supporting edge 14 that is shorter than the first distance d1 (Figure 4).

In particular, the second element 10 is rotatable around the axis A and along the above-mentioned transverse plane between the first position and the second position.
The second element 10 comprises a wall 16, a lower wall in the illustrated figures, which defines, in use, the above-mentioned support surface in relation to the snow-covered terrain.
In other words, the wall 16 is configured to cooperate in contact with the snow-covered terrain, to support the user and avoid the excessive sinking of the tip 5 into the terrain itself.
The wall 16 includes a first surface 17 between the supporting edge 14 and the tip 5 and a second surface 18 between the leading edge 15 and the tip 5.
The first surface 17 defines a supporting surface, the second surface 18 defines a leading surface.
According to the invention, the area of the first surface 17 is variable, by moving the second element 10 between the first position and the second position, in particular by rotating the second element 10 around the axis A between the first and the second position, between a first area when the second element 10 is in the first position (Figure 3), and a second area having smaller dimensions than the first area, when the second element 10 is in the second position (Figure 4).
In other words, when the second element 10 is in the first position, the distance d1 between the supporting edge 14 and the first edge portion 12 is greater and, as a result, the area of the wall 16, between the supporting edge 14 and the tip 5, is greater.
In contrast, when the second element 10 is in the second position, the distance d2 between the supporting edge 14 and the first edge portion 12 is smaller and, as a result, the area of the wall 16, between the supporting edge 14 and the tip 5, is smaller.
In light of the above, the first position advantageously defines an uphill configuration of the basket 7, in which the second element 10 provides a larger support surface during the uphill leg, so as to avoid excessive sinking of the tip 5 in the snow. The second position advantageously defines, in contrast, a downhill configuration of the basket 7, in which the second element 10 provides a support surface that is smaller during descent, so as to avoid the sticking of the basket 7 itself in the snow, but, at the same time, provides the necessary stabilisation.
It should be noted, therefore, how the supporting edge 14 is defined by a first edge portion of the second element 10 (Figure 3), when the second element 10 is in the first position, or by a second edge portion of the second element 10 (Figure 4), when the second element 10 is in the second position.
Conveniently, the first element 8 comprises an axial through hole 20 that is suitable for being engaged by the rod 2 so as to determine the integral fixing of the first element 8 to the rod 2; the second element 10 also comprises an axial through hole 21 engaged by the rod 2 in order to determine the coupling of the second element 10 to the rod 2.
Conveniently, as shown in Figure 2, the hole 21 is eccentric in relation to the axis A.
In this way, by rotating the second element 10 around the axis A, it is possible to determine the first and second position of the second element 10 itself as specified above, i.e., defining different distances d1, d2 between the supporting edge 14 and the first edge portion 12.
Preferably, the basket 7 comprises, in addition, a third element 22 (Figure 2), defined by a respective ring nut, and which can be coupled, so it can be released, to the first element 8.
Specifically, the third element 22 comprises a perimeter portion 23 and a central projecting part 24 protruding axially from the perimeter portion 23 and configured to cooperate with a receiving portion of the first element 8 in order to determine said releasable coupling.
Conveniently, the second element 10 is axially placed between and axially pressed between the first element 8 and the third element 22, so as to be movable between the first and second position with interference with the first element and the third element.
In practice, in use, the user needs to apply a certain rotational force to the second element 10 to be able to move the second element 10 between the first and the second position.
Preferably, the projecting part 24 comprises a shaped side wall including multiple radial protrusions 25; the hole 21 of the second element 10 comprises a side wall 26 including multiple radial recesses 27.
In use, the side wall 26 is configured to cooperate in contact with the side wall of the projecting part 24, so that the radial protrusions 25 engage first radial recesses 27 when the second element 10 is in the first position, and second radial recesses 27 when the second element 10 is in the second position.
In this way, a firm positioning of the second element 10 is ensured selectively in the first or in the second position and, thus, in the uphill or downhill configuration, avoiding undesired movements of the second element 10 itself.
Advantageously, the second element 10 is made of a more flexible material than the first element 8.
In particular, the second element 10 is made of an elastomeric material, i.e., a plastic material that is elastically deformable.
In this way, the user can temporarily deform, just using their hands, the second element 10 so as to temporarily reduce the interference with the first element 8 and, where present, the third element 22 and determine, thus, a quick and easy movement of the second element 10 between the first position and the second position.
From an examination of the features of the pole 1 produced according to this invention, the advantages that it enables are clear.
In particular, the pole 1 can be easily switched between one uphill configuration (Figure 3) and a downhill configuration (Figure 4) by simply rotating (in particular by 180°) the second element 10 of the basket 7.
The pole can also be easily switched into one or more intermediate positions between the uphill and the downhill configurations, by rotating the second element 10 of the basket 7 by a number of degrees between 0° and 180° so as to adapt the dimensions of the tip to the steepness of the slope or to the quality of the snow.
This enables the user to bring with them just one pair of poles 1, for example during a combined sports excursion involving skiing and ski mountaineering or skiing and hiking.
In addition, this invention means the user does not have to bring with them several pairs of baskets specific to each activity, thus avoiding bulky replacements and reducing (to zero) the risk of losing these baskets.
Finally, this invention enables the user to save the space that would otherwise be used by an additional pair of poles and, as a result, to reduce the overall weight being transported.
It is clear that changes may be made to the pole 1 described and illustrated herein, and variations produced thereto, without, for this reason, departing from the scope of protection defined by the claims.
