Abstract

The stick i.e. touring ski stick (10), has a grip region (14) for gripping the stick, and a stick tip region (18) for placement on an underground (U). The stick tip region comprises tip sections, so that one of the tip sections or both the tip sections contact the underground as a function of an angle (W0) in a forward direction between the stick and the underground. Tip directions of the tip sections are pointed in different directions. The tip sections are asymmetrical to each other with respect to a stick axis direction (S).

Description

The present invention relates to a mountain sports pole, comprising a grip area for gripping the mountaineering sports stock and a pole tip area for placing on a substrate. In particular, the invention relates to a touring ski pole.

Mountaineering poles are used to equip hikers, mountaineers, touring skiers, mountaineers, or the like and, on the one hand, support the upward movement of the mountain by the muscular strength of the arms and, on the other hand, provide safety and support by supporting the balance of the body during ascent and descent. The mountaineering pole is gripped in a grip area by the user and placed on the ground with a pole tip area, the pole tip area usually having a metal tip to provide non-slip grip on the mountain.

In order to properly support the body weight, the mountain sports pole is generally placed approximately vertically. With a steeply rising or falling underground, i. when moving on the mountain, then the tip of the pole tip area is no longer orthogonal to the ground but in a sometimes quite acute angle, so that the slope force due to the support of the user can cause the cane area slips off the ground and the safety of the user particularly is endangered on steep slopes or on slippery surfaces.

To solve this problem, it is known to angle the tip portion of the mountaineering pole so that it does not point in the stick axis direction, but at an angle obliquely in the forward direction. When supporting the mountaineering stock on a rising slope then penetrates the Top section at significantly steeper angle to the ground in the ground and thus finds better grip.

The disadvantage of this solution, however, is that for the higher holding force during ascent a greater risk of slippage of the pole tip area must be accepted during the descent, since the inclined in the forward direction tip section in sloping ground in an even shallower angle on the ground as in a mountain sports stick with straight top section. For passages with steeper descent, the mountaineering pole must therefore be turned occasionally around the pole axis direction by 180 ° so that the pole tip area finds sufficient support in the ground. However, this handling is associated with the problem that the usually ergonomically shaped grip area can not be taken safely or comfortably and also a retaining loop on the handle area can not be used. In addition, the rotation of the sticks means an unwanted interruption of the movement.

The above-mentioned problems are particularly pronounced in the area of touring skiing. The user often moves here on icy ground or slippery rock, is also exposed to harsh weather conditions and is on touring skis, so that the support on the mountain sports sticks special importance.

Against this background, it is the object of the present invention to provide a mountaineering pole, in particular a touring ski pole, which offers a secure grip even on difficult and slippery surfaces to a user during ascent and descent on the mountain.

To solve this problem, the invention provides a mountaineering pole, comprising a grip area for gripping the mountaineering pole and a pole tip area for placing on a substrate, wherein the pole tip area at least a first tip portion and a second tip portion such that depending on a forward angle between the mountain sport pole and the ground on which the pole tip area is seated in use, the first tip portion or the second tip portion or both tip portions contact the ground.

During ascent, the angle in the forward direction between the mountain sports floor and the ground is less than 90 °, while during the descent, this angle is greater than 90 °. If, according to the invention, the first tip section or the second tip section or both tip sections contact the ground in dependence on said angle in the forward direction between the mountain sport pole and the ground, then at least one of the two tip sections can always be set up to secure the mountaineering pole during ascent and one second of the tip sections may be set up for a safe hold of the mountaineering pole on descent. Thus, the mountain sports stock according to the invention can intervene optimally both the ascent and descent on the ground.

Preferably, the mountaineering pole defines a forward direction, in particular by an ergonomic design of the grip region and / or by the arrangement of a loop on the grip region and / or by the design of a snow plate, which may have a smaller extent in the forward direction than in the backward direction. When the mountaineering pole has no special features for specifying a forward direction, references to the forward direction in the following description and in the claims, respectively, are to be understood such that the respective configuration of the pole tip area may dictate a forward direction of the mountaineering pole. This forward direction can then be chosen arbitrarily with respect to the remaining parts of the mountaineering sport.

The mountaineering pole further defines a pole axis direction, which of the handle region extends to the pole tip region, wherein along the pole axis direction usually extends a rod-shaped main portion of the mountain sports stock. But even mountain sports poles deviating from a straight bar shape are, by definition, intended to have a pole axis direction from the grip area to the pole top area.

In the following, reference will be made remotely to a tip direction defining each tip portion, with the respective tip portion tapering along its tip direction. If the tip section is formed, for example, by opposing straight flanks which enclose an acute angle between them, the tip direction runs along the angle bisector of the angle between the flanks.

In a preferred embodiment of the invention, the tip directions of the two tip sections are in different directions. Although a variant of the invention is conceivable in which two separate tip portions are provided with parallel tip directions, however, the alignment of the tip directions in different directions allows an angle between an active, i. contacting the ground, top section and the ground for the ascent as well as for the descent can each have a suitable value.

In tests of the inventors, it has been found that the support loads on the tip sections differ during ascent and descent. This is attributed to the fact that the movement and the posture of the user are different during ascent and descent. Therefore, embodiments have proven to be particularly advantageous in which the tip sections are asymmetrical to each other with respect to the pole axis direction, so that a first of the tip sections is adapted specifically for the rise, while a second of the tip sections is adapted specifically for descent.

An asymmetrical arrangement of the tip sections is e.g. characterized in that the tip directions of both tip portions with the pole axis direction include an angle different in magnitude, and the tip direction of a tip portion is parallel to or along the pole axis direction, while the tip direction of the other tip portion is at an angle to the pole axis direction. An alternative or additional possibility of the asymmetrical arrangement of the tip portions is that the tips of the two tip portions (i.e., the foremost portions of the tip portions where the tip portions first contact the ground) are staggered in the stub axle direction.

In a preferred embodiment, the tip direction of the first tip portion extends obliquely in the forward direction and in the stem axis direction. The first tip section is then particularly suitable for engagement on a rising terrain during the ascent and penetrates as steep as possible into the ground. With respect to the angle of the tip direction of the first tip portion with respect to the pole axis direction, it has been found that this angle should be between about 25 ° and about 45 °, since the tip portion is then particularly suitable for slope slopes for which the additional support is provided by the invention Stick tip area is particularly desirable.

Regardless of the first tip portion, the tip direction of the second tip portion may be substantially in the pole axis direction. This provides satisfactory grip on descent and also high stability of the pole tip area due to the second tip section centrally located on the pole axis direction. However, the second tip section may also have a tip direction, which extends at an angle to the pole axis direction and preferably runs obliquely in the backward direction and the pole axis direction in order to a possible steep contact angle to ensure a sloping ground during descent.

It has also proven to be advantageous to have a pole tip region in which the tip of the first tip section in the pole axis direction extends further than the tip of the second tip section. In this case, if the first tip section is arranged in the forward direction in front of the second tip section, it can be achieved in this configuration that both tip sections can be brought into contact with the ground at the same time during descent and thus slipping of the mountaineering pole during descent can be prevented even better.

The cane area according to the invention can be designed inconspicuously if, in a plane orthogonal to the pole axis direction, the outside dimensions of a main body of the mountaineering pole are greater than the maximum extent of the tip sections. The tip sections then do not protrude orthogonally to the pole axis direction beyond the outer contour of a main body of the mountaineering pole (in particular a connecting section between grip area and pole tip area), thereby further reducing the risk of injury.

A mountaineering pole of the present invention can be produced inexpensively if the tip sections are formed as pointed projections integrally on a tip body. Thus, in particular, a conventional mountaineering pole can be converted to a mountain sports pole according to the invention by using such a tip body. It is also thought to insert the tip body in an opening at a tip-side longitudinal end of a pole main body, so that the tip body may preferably be formed of a different material than the main body of the mountaineering pole.

The advantages of the present invention are particularly useful when the mountain sports stock is used in winter sports and accordingly has a snow plate. This is especially thought of ski touring poles, which are exposed to special loads in snow and ice and generally encounter slippery or wet ground. Tests on iced ground have shown a safe hold of the mountain sports poles according to the invention both during ascent and during descent.

To achieve the object of the invention, the present invention further provides a tip body comprising at least a first tip portion and a second tip portion, wherein the tip body has a mounting portion for mounting on a mountain sports stock, such that in an assembled state of the tip body in response to an angle in the forward direction between the mountain sports floor and the ground on which the tip body rests in use, the first tip portion or the second tip portion or both tip portions contact the ground.

The tip body of the invention forms a pole tip portion of the above-described mountaineering pole according to the invention and may be further developed by one or more of the features described above with respect to the pole tip region to achieve the advantages and effects mentioned above for the respective features.

The invention will be explained in more detail below with reference to a preferred embodiment with reference to the accompanying drawings. Showing:

FIG. 1

a side view of a ski pole according to an embodiment of the present invention;

a perspective view of a tip body of the in FIG. 1 shown ski poles; and

FIG. 5

a side view of the in FIG. 4 shown top body.

An in FIG. 1 Skistock 10 shown in side view comprises a rod-shaped main body 12, a handle portion 14 disposed at the upper end of the main body 12, a disc portion 16 disposed at the lower end of the main body 12, and a pole tip portion 18 disposed at the lowermost end of the ski pole 10 adapted to Underground U, in the case shown, a slope inclined to a horizontal plane H, to contact. From the grip region 14 to the pole tip region 18, a pole axis direction S. extends along a pole axis AS.

The grip region 14 has a handle 20 with a grip loop 22. The ergonomic shape of the handle 20 as well as the position of the strap 22 define a forward direction V of the ski pole 10 along which a user of the ski pole 10 grasping the ski pole 10 in normal use position on the handle portion 14 advances, the forward direction V parallel to a horizontal plane H is defined.

The main body 12 is formed of a light metal tube whose central axis coincides with the pole axis direction S. The main body 12 may include a telescoping tube system to adjust the length of the sports stock 12.

In the plate area 16, a snow plate 24 is attached to the main body 12. In the embodiment, the snow plate 24 is asymmetrical with respect to the Main body 12, wherein a lying in the forward direction V portion of the snow plate 24 is smaller than a lying in the forward direction V opposite rearward portion of the snow plate 24. In this way, the snow plate 24 defines the same forward direction V as the handle portion 14th

The pole tip area 18 of the ski pole 10 will also be described below with reference to FIG FIGS. 2 to 5 explained in more detail.

FIGS. 2 and 3 show a made of a plastic injection molded snow plate base body 26 to which the snow plate 24 is integrally formed and which has a first, along the Stockachserichtung S extending bore 28 into which a lower end 30 of the main body 12 is inserted, and a second , along the Stockachserichtung S extending bore 32, in which a tip body 34 is inserted.

The in FIGS. 4 and 5 individually shown tip body 34 is cut from a plate-shaped metal material and includes a mounting portion 36, with which the tip body 34 is inserted into the second bore 32 of the snow plate main body 26, and a first tip portion 38 and a second tip portion 40. In the first tip portion 38th The tip body 34 tapers between two straight flanks 42a, 42b to a first tip 42 (pointed edge). In the second tip section 40, the tip body 34 tapers between two straight flanks 44a, 44b to a second tip 44 (pointed edge). An angle bisector between the flanks 42a, 42b of the first tip section 38 defines a tip direction R1 of the first tip section 38. Similarly, an angle bisector between the flanks 44a, 44b of the second tip section 40 defines a tip direction R2 of the second tip section 40.

As in FIG. 5 illustrated, the tip directions R1, R2 of the two Tip sections 38, 40 in different directions. Furthermore, the two tip sections 38, 40 are asymmetrical with respect to the pole axis direction S. The tips 42, 44 of the two tip sections 38, 40 are staggered in stance axis direction S, with the first tip 42 extending farther in the stinger direction (deeper) than the second tip 44, ie, the total length of the stile 10 in the stance axis direction S through the first tip 42 is set.

The tip direction R1 of the first tip section 38 extends obliquely in the forward direction V and in the tree axis direction S. Here, an angle W1 by which the tip direction R1 is inclined in the forward direction with respect to the pole axis direction S is approximately 35 ° in the exemplary embodiment.

The tip direction R2 of the second tip portion 40 extends obliquely in the backward direction R and in the stem axis direction S. Here, an angle W2 between the tip direction R2 of the second tip portion 40 and the pole axis direction S is smaller than the angle W1 between the tip direction R1 of the first tip portion 38 and the pole axis direction S. In the exemplary embodiment, the angle W2 is approximately 15 °. At the same time, the second tip 44 lies substantially on the pole axis AS, so that a tilting moment on the pole during placement of the second tip section 40 is avoided.

In FIG. 5 It can also be seen that an angle W3 between the flanks 42a, 42b of the first tip 42 is smaller than an angle W4 between the flanks 44a, 44b of the second tip 44. In the exemplary embodiment, the angle W3 is approximately 30 ° and the angle W4 a size of about 70 °. Further, to simplify manufacture, the outermost flanks of the tip body 34, ie, the flank 42a of the first tip 42 and the flank 44a of the second tip 44, are parallel to each other and the inner flanks 42b (the first tip 42) and 44b (the second tip 44) ) meet at an angle.

Furthermore, in the FIGS. 1 and 2 to recognize that the tip sections 38, 40, in spite of their obliquely extending tip directions R1, R2 not or not substantially over the outer contour of the main body 12 protrude, ie in a direction orthogonal to the pole axis direction S form no disturbing projections. This can avoid that the user with the stick tip area 18 due to the special design of the tip portions 38, 40 gets stuck. In addition, the tips 42, 44 are then located relatively close to the pole axis AS, so that tilting moments on the pole 10 can be reduced.
