Crampons with shaft and locking mechanism

Abstract

The crampon with shaft and locking mechanism (Fig.1A, Fig.1B, Fig.2A and Fig.2B) has a retaining bolt with a tension spring.

Description

[0001] The crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) is designed for touring skis with an existing crampon attachment (03) for PIN ski touring bindings (02 and 03). The manufacturer of the PIN ski touring binding (02 and 03) has no influence on its function. The crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) can be used with all common PIN ski touring bindings (02 and 03) with crampon attachment (03).

[0002] The crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) is inserted into the existing crampon attachment (03) of the PIN ski touring bindings (02 and 03).

[0003] A ski tourer may encounter a situation on a ski tour where, due to the terrain, ascent becomes very difficult or even impossible without crampons. The climbing skins under the skis have little or no grip due to freezing crust or icing of the snow.

[0004] Often, ski tourers don't anticipate needing crampons at the start of their tour. Climate change is making conditions increasingly challenging for ski touring. Rain, rising daytime temperatures, and subsequent nighttime cooling are leading to more frequent occurrences of hard-packed or icy tracks on ski tours. The transition from soft snow, which provides good grip for climbing skins, to extremely challenging conditions within just a few meters, where ski tourers would certainly appreciate crampons.At the start of a ski tour, ski tourers usually pack their crampons in their backpacks. This means that during the tour, when crampons would be advantageous, it can be difficult to retrieve them. For example, if the ski tourer is already standing on steep, hard-packed, or icy snow and could lose their footing on their skis when putting down their backpack, they might slip. Even if the ski tourer has the crampons readily available, it can be difficult to attach them to the crampon attachment points under the ski boots in such situations. This is especially true for older ski tourers with cold hands, as it can be challenging to secure the crampons to the attachment points while the touring skis are already locked in place.

[0005] The crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) can already be fixed in the crampon attachment (03) if the ski tourer anticipates that a difficult situation might arise on the ski tour in which a crampon with a wave and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) would be advantageous. They are immediately ready for use and can be activated remotely.

[0006] Now comes the crampon with shaft and locking mechanism, which was already mounted before the start of the ski tour ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) to use. Without taking off the backpack and taking out the crampons and mounting the crampons on hard-packed and icy ground, which can lead to fatal consequences in steep terrain.

[0007] There is a promotion position ( Fig. 3A and Fig. 4A) without triggering the crampon cheeks (04), here neutral position ( Fig. 3A and Fig. 4A). The neutral position ( Fig. 3A and Fig. 4A) is also the departure position ( Fig. 3A and Fig. 4A). There is a promotion position ( Fig. 3B and Fig. 4B) with release of the crampon cheeks (04), here active position ( Fig. 3B and Fig. 4B).

[0008] The crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) can unlock the retaining latch (10) by pressing with the ski pole and attach the crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) activate and from the neutral position ( Fig. 3A and Fig. 4A) into the active position ( Fig. 3B and Fig. 4B).

[0009] The crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) is inserted into the existing crampon attachment (03) on the PIN ski touring binding (02 and 03) before the start of the ski tour. The shaft, equipped with a spring (08) to which the crampon cheeks (04) are attached, is moved into the neutral position ( Fig. 3A and Fig. 4A), and using the retaining bolt with locking and unlocking mechanism (10) on the crampon with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) is attached. The crampon cheeks (04) are now in neutral position ( Fig. 3A and Fig. 4A), which is used for climbing with climbing skins and for skiing down without climbing skins.

[0010] If the ski tourer is ascending in exposed, steep and icy terrain, and wants to use crampons with a wave and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) into the active position ( Fig. 3B and Fig. 4B) to activate, he simply needs to use the ski pole to operate the locking and unlocking mechanism (10). The crampon with shaft and locking device ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) is unlocked. The spring on the shaft now pushes the crampon cheeks into the active position ( Fig. 3B and Fig. 4B). The simultaneously engaging retaining bolt with locking and unlocking mechanism (10) prevents the square shaft (05) from kicking back. The retaining bolt now blocks the square shaft (05) in a groove in the shaft (09), so that even under heavy load from the ski tourer, the crampon with shaft and locking mechanism cannot kick back ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) is prevented.

[0011] The retaining bar (10), which is engaged in the groove in the shaft (09), now prevents the square shaft (05) with the attached crampon cheek (04) from being pushed back by the pressure and load of the ski tourer and thus losing its grip on the ground. The crampons with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) now engage in the hard-packed or frozen snow like ordinary crampons.

[0012] Are the crampons equipped with a shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) no longer eligible to move up to the active position ( Fig. 3B and Fig. 4B) required, the ski tourer has two options: The crampon cheeks (04) can be pulled out of the groove in the shaft (09) by pressing and unlocking the retaining bolt with locking and unlocking mechanism (10) and into the neutral position ( Fig. 3A and Fig. 4A). The ski tourer can then either ski down without skins or continue ascending and, if necessary, attach the crampons with wave and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) reactivate. Second option: the ski tourer removes the crampons with wave and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) from the PIN ski touring bindings (02 and 03) and begins the descent.

[0013] The crampons in the neutral position with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) do not impair the downhill performance or the safety function of the PIN ski touring binding (02 and 03).

[0014] Crampons with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) thus provide an additional safety benefit for ski tourers.

[0015] The crampons with shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) are not to be used on stones, rocks, branches, roots and bare ice. Likewise, crampons with a shaft and locking mechanism ( Fig. 1A, Fig. 1B, Fig. 2A and Fig. 2B) in the active position ( Fig. 3A and Fig. 4A) not suitable for departure.
