Ski pole

The invention "relates to a ski pole with at least a nail-like tip for secure support on firm or icy ground

In "known ski poles of this or a similar type the nail-like tip is often the cause of sometimes serious injuries in skiing accidents «even when handling, for example, loading or stacking with such known ski sticks were often stitch or. Bite wounds caused by the uncovered tips «To avoid such injuries. one has already the tips of the ski poles are no longer sharp and precisely conical, but rather with a dome-shaped one Completion. When using ski sticks of this type, however, it turned out that the user special on blocked slopes, icy sections of the route and harsh subsurface do not have sufficient hold of the stick, even with abnormally strong use of the Could reach ski pole tip.

The object of the invention is to create a ski pole which avoids the disadvantages of the known, in particular aleo ensures a secure support of the ski look on any surface and beyond

109808/0183

The risk of injury is limited to a minimum has as little extra weight as possible compared to already known ski poles and which is also economical can be produced.

The object is achieved according to the invention in a ski pole of the type defined at the outset in that the nail-like Tip arranged movable relative to a dome-shaped end piece and when the ski pole shaft is loaded can be displaced from a position completely covered by the dome-shaped terminating piece into a position in which it terminates the dome-shaped Final piece towers above. In particular, the nail-like tip in a central guide provided in the dome-shaped end piece in the longitudinal direction of the stick movable.

In terms of construction, the two simple solutions are primarily available, that either the nail-like Tip with its head firmly arranged on the ski pole shaft or rests against the movable end of the ski pole shaft with the front of your head

Appropriately, can be used to hold back the nail-like Tip in her covered by the dome-shaped abachlußstück Each position should be provided when the ski pole is not loaded.

For holding the dome-shaped closure piece to the Skistocksohaft and to protect the spring may be provided a profiled sleeve leg, the comparable longitudinally movable form-fitting manner to the lower end of the Ski8tockscb, aft8

is bound. This sleeve also allows the entire tip part with the aforementioned features as a separate one Commercial object to put on normal ski poles, so that these can be easily done in accordance with the subject matter of the invention can be converted. For this reason "element protection" is claimed for the tip part.

A significant advantage of the ski pole of the invention is other than in the prevention of injuries or in a kind of catapult effect _y in particular occurs when the snow plate is mounted on the outer circumference of the profiled sleeve, and then the discharge of the ski pole eioh by the spring stored ι energy against the snow surface "The catapult effect can be changed almost at will due to the different dimensions of the spring and thus be adapted to the individual habits and requirements of the skier. Another advantage is durt ';, the arrangement of a locking device to determine the ..lagel-like tip both in the retracted, deh. from the other side section covered position as well as in its exposed position in which it protrudes beyond the end of the ski pole. What is achieved here is that, depending on the condition of the slope, the user either considers a constant protrusion of the nail-like tip necessary, as it could be when driving through the narrow and already icy slalom course very quickly, with short, • fast and precisely defined pole operations arrives, or beäjaer training of beginners in deep snow, in which the exact piece use is still largely insignificant, but the IJnfallgeafahr is very large and he

109808/0163

thus the tip of the ski pole "is better kept hidden, the locking device is actuated with a small handle and the nail-like tip is in the desired position Position.

Due to the arrangement of the actuating device of the locking device on the upper part of a handle provided on the ski pole shaft, it is also possible to use the locking device can also be used while driving.

The following are some exemplary embodiments of the invention explained in more detail with reference to drawings. Show it:

109008/0103 ~ ⁷ "

To lock the tip 1 both in its concealed position and in the position which protrudes from the dome-shaped end piece. In this illustration, 8 locking blocks 16 are pivotably mounted at pivot points 17 in the interior of the ski pole shaft. A spring 18 deflects the locking blocks 16 around the pivot points 17 and presses them through longitudinal slots 19 between the guide rings 9 arranged at the corresponding points on the circumference of the ski “pole shaft 8” so that the slightly angled ends 20 of the locking blocks 16 cause the longitudinal displacement between the sleeve 6 and the ski pole shaft 8 blocked. For a blockage in both directions of displacement, only the complementary design of locking blocks 16 and abutments (for example the guide rings 9) need to be coordinated with one another.

The operation aer locking device can beispielsvi® ^"; se from the top of the handle 21 sm & made ₃ to a reversing lever is recessed 22 which is deflected at eineiü eccentric pivot point 25 between the Peststellklötzen 16 and a suspension point 24 on the lever 22 is a thin wire. 25 excited.

In the position of the reversing lever according to FIG. 7, the wire rope 25 is moved in relation to the pivot points 17 of the locking blocks 16 in the direction of the handle 21 and pulls the locking blocks 16 against the force of the spring 18 in a neutral division, so that a dtr load .proportionales emergence the nail-like tip 1, is possible unhindered.

Depending on whether at the moment the lever is actuated 22 the ski pole was loaded or unloaded, the locking of the nail-like tip 1 takes place in the concealed or in the superior position of the dome-shaped terminating piece.

According to the Pig. 1 and 3 , the snow plate 26 of the Skietefcke can be arranged on the profiled sleeve 6 and firmly connected to it via clamping rings 27. When the ski pole according to the invention was tested, it was found that this arrangement results in an additional pushing off of the user when the ski pole shaft 8 is relieved by the stored energy of the Eeder 4. In the illustration according to FIGS. 4 and 6, on the other hand, the snow plates are attached to angled sleeves 28 fixedly connected to the ski pole shaft 8.
