Description

Aus einer am Hinterende des Schneeschuhes beweglichen, in den Schnee eingreifenden Abstützplatte bestehende Rückgleitsicherung für Schneeschuhe Im Patent 445 911 ist eine Vorrichtung patentiert, bei welcher in einiger Entfernung hinter dem Schneeschuh eine drehbare Klappe liegt, die beim Zurückgleiten des Schneeschuhes in ihrer annähernd vertikalen Arbeitsstellung durch einen hoch außerhalb des weggedrückten Schnees befindlichen Anschlag gehalten wird. Die Praxis hat ergeben, daß diese Vorrichtung bei jeder Schneeart gut wirkt, jedoch hat sich der Nachteil ergeben, daß es nötig ist, zwecks Erlangung der durch die Konstruktion bedingten nötigen Festigkeit den Schwerpunkt des Schneeschuhes zu verlegen, da die Vorrichtung etwas scliwer wird, zumal bei Anbringung an alten Schneeschuhen. was praktisch der häufigste Fall ist, eine nachträgliche Berücksichtigung der Schwerpunktsverlegung am Schneeschuh durch Veränderung der Entfernung zwischen Schneeschuhspitze und Bindung gar nicht oder nur schwer möglich ist.From a movable at the rear end of the snowshoe into the snow engaging support plate existing anti-slip protection for snowshoes In the patent 445 911 is a patented device in which at some distance behind The snowshoe has a rotatable flap that opens when the snowshoe slides back in their almost vertical working position by a high outside of the pushed away Snow located stop is held. Practice has shown that this device Works well in every type of snow, but has the disadvantage that it is necessary is, in order to achieve the necessary strength required by the construction Relocate the center of gravity of the snowshoe, as the device becomes a little more difficult, especially when attached to old snowshoes. which is practically the most common case, a subsequent consideration of the shift in the center of gravity on the snowshoe No change in the distance between the snowshoe tip and the binding or is difficult to do.

Durch vorliegende Erfindung wird der unbedingt notwendigen Forderung, daß die Klappe nicht das Hinterende des Schneeschuhes berührt, Rechnung getragen und dabei doch eine sehr leichte und dabei genügend feste Ausführung geschaffen. Abb. i zeigt die Erfindung im Aufriß (Mittelschnitt) und Abb. 2 den Grundriß. i ist das Schneeschuhende. Die Platte 2 ist an dem Schneeschuh mit Holzschrauben 5 befestigt; bei sehr dünnen Schneeschuhen kann man auch unten versenkte, durchgehende Nieten verwenden. Diese Platte 2 hat zwei aufgebogene Lappen, welche die feststehende Welle 8 tragen; die Seitenflächen sind zweckmäßig durch die Aufbiegung 7 am Hinterende der Platte versteift, so daß sie aus dünnem Bleche bestehen können. Um den Bolzen 8 dreht sich die Klappe 3. Diese hat zwei Rippen 6, «-elche einmal die Klappe selbst versteifen, so daß sie aus dünnem Stahlbleche bestehen kann. Diese Stege 6 läßt man nun erfindungsgemäß sich an die Hinterenden des Schneeschuhes anlegen, so daß sich die Klappenfläche 3 selbst nicht gegen das Schneeschuhende anlegen kann, es bleibt vielmehr der gewünschte große Zwischenraum aufrechterhalten. Eine Feder 4 drückt die Klappe nach unten, damit sie nicht klappert. Abb. i zeigt ferner die drei charakteristischen Stellungen: A Ruhestellung (außer Betrieb) etwa bei großen Abfahrten, B die normale Stellung beim Vorwärtsgleiten, wobei die Klappe, ohne zu hemmen, nachgleitet, C die Sperrstellung, in die die Klappe bei jeder Rückwärtsbewegung gerät und sich fest in den Schnee einbohrt.The present invention fulfills the absolutely necessary requirement that the flap does not touch the rear end of the snowshoe is taken into account and at the same time created a very light and at the same time sufficiently solid design. Fig. I shows the invention in elevation (middle section) and Fig. 2 the plan. i is the snowshoe. The plate 2 is attached to the snowshoe with wood screws 5 attached; with very thin snowshoes you can also go through sunk-in, continuous ones at the bottom Use rivets. This plate 2 has two bent flaps, which the fixed Shaft 8 wear; the side surfaces are expedient by the bend 7 at the rear end the plate stiffened so that they can consist of thin sheet metal. Around the bolt 8 turns the flap 3. This has two ribs 6, "- which is the flap itself stiffen so that it can consist of thin steel sheets. This webs 6 leaves you now according to the invention to put on the rear ends of the snowshoe so that the flap surface 3 itself cannot lay against the snowshoe end, it rather, the desired large gap is maintained. A spring 4 presses the flap down so that it doesn't rattle. Fig. I also shows the three characteristic positions: A rest position (out of operation) for example with large Departures, B the normal position when gliding forward, with the flap without closing inhibit, slides, C the locking position into which the flap moves with every backward movement and bores itself firmly into the snow.

Durch die vorstehende leichte Ausführung wird es möglich, ohne Verlegung des Schwerpunktes die Vorrichtung an jedem Schneeschuh anzubringen.Due to the above light design, it is possible without laying the center of gravity to attach the device to each snowshoe.
