Description

Bei der herkömmlichen Sprungschibindung besteht sowohl im Flug als auch bei der Landung keinerlei Sicherheit.With conventional ski jump bindings, there is no security either in flight or when landing.

Ziel der Erfindung ist die Schaffung einer solchen Sicherheitsbindung für Sprungschi. Dies wird bei einer Kombination einer Sicherheits-Sprungschibindung mit einem Sprungschuh, bei welcher der vordere Teil des Sprungschuhs zwischen den seitlichen Flügeln einer am Sprungschi befestigten Sprungbindung bis zu einem Anschlag einschiebbar ist, erfindungsgemäß dadurch erreicht, daß in an sich bekannter Weise im oberen Abschnitt eines nach vorne vorspringenden Teils der Sohle des Sprungschuhs eine halbkugelförmige Ausnehmung vorgesehen ist, in die ein an der Sprungbindung unter einstellbarer Federbelastung verschiebbar gelagerter Bolzen mit halbkugelförmigem Kopf eingreift und daß zwischen oberem und unterem Teil der Sohle des Sprungschuhs ein Einschiebeschlitz zur Aufnahme mindestens einer Blattfeder vorgesehen ist. Mit dieser erfindungsgemäßen Kombination ist nicht nur eine einwandfreie Führung des Schis beim Sprung, sondern auch eine Auslosemöglichkeit im Falle eines Sturzes gegeben.The aim of the invention is to create such a safety binding for ski jumps. This is achieved according to the invention in a combination of a safety jump ski binding with a jump shoe, in which the front part of the jump shoe can be inserted up to a stop between the side wings of a jump binding attached to the jump ski, in that, in a manner known per se, in the upper section of a forwardly projecting part of the sole of the spring shoe is provided with a hemispherical recess into which a bolt with a semi-spherical head which is displaceably mounted on the spring binding under adjustable spring load engages and that an insertion slot is provided between the upper and lower part of the sole of the spring shoe for receiving at least one leaf spring . With this combination according to the invention, not only is the ski guided properly when jumping, but there is also a possibility of being released in the event of a fall.

Gemäß einer weiteren Ausgestaltung der Erfindung kann in den Einschiebeschlitz eine Blattfeder und oberhalb derselben eine Begrenzungsblattfeder einschiebbar sein. Damit ist eine Begrenzung der Vorlage beim Sprung erreichbar. Gemäß einer vorteilhaften Weiterbildung der Erfindung kann dabei vorgesehen sein, daß die Begrenzungsblattfeder mittels einer Schraubenmutter-Anordnung in Längsrichtung der Sohle des Sprungschuhs verschiebbar ist. Dadurch kann diese Vorlage-Begrenzung den individuellen Gegebenheiten angepaßt werden.According to a further embodiment of the invention, a leaf spring and above it a limit leaf spring can be inserted into the insertion slot. This means that the template can be limited when jumping. According to an advantageous development of the invention, it can be provided that the limiting leaf spring can be displaced in the longitudinal direction of the sole of the jumping shoe by means of a screw nut arrangement. As a result, this template limitation can be adapted to individual circumstances.

Eine weitere zweckmäßige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß ein über ein Gelenk schwenkbar an der Sprungbindung gelagerter Bügel zum Anheben des Bolzens entgegen der Federbelastung vorgesehen ist. Dadurch wird der Ein- und Ausstieg in die bzw. aus der Bindung erleichtert.A further expedient embodiment of the invention is characterized in that a bracket which is pivotably mounted on the spring binding via a hinge is provided for lifting the bolt against the spring load. This makes it easier to get in and out of the binding.

Die Erfindung wird nunmehr unter Bezugnahme auf die Zeichnungen näher erläutert. In diesen zeigen: Fig. 1 eine Gesamt-Seitenansicht der erfindungsgemäßen Kombination einer Sicherheits-Sprungschibindung mit einem Sprungschuh, die Fig. 2A-2D Details des Einschiebeschlitzes am Sprungschuh und der darin eingeschobenen Blattfedern, die Fig. 3A-3D weitere Details dieses Einschiebeschlitzes und der Blattfedern, die Fig. 4A-4F Details der Einrichtung zur Sicherheitsauslosung im Falle eines Sturzes, die Fig. 5A eine Draufsicht auf die Sprungbindung und die Fig. 5B eine Seitenansicht der Sprungbindung mit dem Ein-Ausstieg-Bügel.The invention will now be described with reference to the drawings explained. 1 shows an overall side view of the combination according to the invention of a safety ski ski binding with a jumping shoe, FIGS. 2A-2D show details of the insertion slot on the diving shoe and the leaf springs inserted therein, FIGS. 3A-3D show further details of this insertion slot and the leaf springs, FIGS. 4A-4F details of the device for safety triggering in the event of a fall, FIG. 5A a top view of the jump binding and FIG. 5B a side view of the jump binding with the entry-exit bracket.

Am Sprungschi 1 ist die Sprungbindung 2 mit den beiden Seitenflügeln 3 mittels Schrauben 4 angebracht, in die der Sprungschuh 5 hineingeschoben wird (Fig. 1).The jump binding 2 with the two side wings 3 is attached to the jump ski 1 by means of screws 4, into which the jump shoe 5 is pushed (FIG. 1).

Beim Einstieg wird der Sprungschuh 5, der an der Vorderteilmitte eine halbrunde bzw. halbkugelförmige Ausnehmung 6 aufweist, (oder eine halbrunde bzw. halbkugelförmige Erhöhung an der selben Stelle und die Ausnehmung am Unterteil des Bolzens 16) in die Sprungbindung 2 eingeschoben.When entering the jump shoe 5, which has a semicircular or hemispherical recess 6 at the center of the front part (or a semicircular or hemispherical elevation at the same point and the recess on the lower part of the bolt 16) is inserted into the spring binding 2.

Darunter befindet sich in der Sohle des Sprungschuhs 5 der Einschiebeschlitz 7, in den die gewölbte Blattfeder 8 eingeschoben wird. Die Blattfeder 8 kann verschiedene Stärken aufweisen. Der Sprungschuh 5 bekommt dadurch eine nach oben hin gewölbte Form. Würde man in die Sprungbindung einsteigen und hinten nach unten drucken, so entsteht ein Federeffekt, der beim Absprung an der Sprungschanze den Sprungschi 1 zum Körper drückt. Der Sprungschi 1 kann somit im Flug nicht mehr vom Körper weggezogen werden. Beim herkömmlichen Springen pendelt der Sprungschi frei, nur der Unterdruck hält ihn zum Körper.Underneath is the insertion slot 7 in the sole of the jumping shoe 5, into which the arched leaf spring 8 is inserted. The leaf spring 8 can have different strengths. The jumping shoe 5 is thereby given an upwardly curved shape. If you would jump into the jump binding and print downwards at the back, a spring effect would result which, when jumping on the ski jump, would push the ski 1 to your body. The jump ski 1 can thus no longer be pulled away from the body in flight. In conventional jumping, the jump ski swings freely, only the vacuum holds it to the body.

Die Begrenzungsblattfeder 9 wird über den Schlitz 7 und über die Blattfeder 8 geschoben. Durch Verdrehen der Schraube 10, die drehbar im Schuh befestigt ist (bei 11), wird die Begrenzungsspannung eingestellt. Die Schraubenmutter 12 ist an der Blattfeder 9 befestigt; durch das Verdrehen der Schraube 10 vor - zurück wird die Blattfeder 9 in den Dreh- bzw. Verschiebebereich 13 eingeschoben und bewirkt eine Verspannung, die auch die Begrenzung ergibt. Eine Querschnitt-Draufsicht siehe Fig. 2A.The limiting leaf spring 9 is pushed over the slot 7 and over the leaf spring 8. By turning the screw 10, which is rotatably fastened in the shoe (at 11), the limiting voltage is set. The nut 12 is attached to the leaf spring 9; by turning the screw 10 forward - back, the leaf spring 9 is inserted into the rotating or sliding area 13 and causes a tension, which also results in the limitation. A cross-sectional top view see Fig. 2A.

Eine Einstellung der Begrenzung ist auch durch das Einschieben verschiedener Blattfederformen in den Einschiebeschlitz 7 möglich. Die Begrenzung durch kürzere oder längere Blattfedern 9 ist hart oder weich zu erzielen. Die Anbringung von Verriegelungsschrauben ist möglich (vgl. Fig. 3A).The limit can also be adjusted by pushing it in Different leaf spring shapes possible in the insertion slot 7. The limitation by shorter or longer leaf springs 9 is hard or soft to achieve. It is possible to attach locking screws (see Fig. 3A).

Nun drückt man den Bügel 14 über das Gelenk 15 nach unten, im selben Moment drückt der Bügel 14 am Ansatz von Bolzen 16 in der Führung die Feder 17 nach oben, die zur Einstellung des Sicherheitsdruckes dient u.zw. mittels der Sicherheitsdruck-Einstellschraube 18. Der Federsitz ist mit 19 bezeichnet (vgl. Fig. 4A).Now you press the bracket 14 down over the joint 15, at the same time the bracket 14 at the attachment of bolts 16 in the guide presses the spring 17 up, which serves to adjust the safety pressure, etc. by means of the safety pressure adjusting screw 18. The spring seat is designated 19 (see FIG. 4A).

Jetzt schiebt man den Sprungschuh 5 unter die beiden Seitenflügel, die im Flug den entstehenden Belastungsdruck aufnehmen, bis zum Vorderteil von Bindung 2. Mit 20 ist ein Anschlag bezeichnet. Draufsicht Seitenansicht (Fig. 5A-5B).Now you push the jumping shoe 5 under the two side wings, which absorb the resulting pressure during flight, up to the front part of binding 2. 20 is a stop. Top view side view (Fig. 5A-5B).

Jetzt läßt man den Bügel 14 über das Gelenk 15 los. Die Feder 17 preßt den Bolzen 16 in die Ausnehmung 6 vom Sprungschuh 5 hinein.Now you can release the bracket 14 via the joint 15. The spring 17 presses the bolt 16 into the recess 6 from the spring shoe 5.

Kommt es beim Aufsprung zum Sturz, so wird der Sprungschuh 5 unter die beiden Seitenflügel 3 über Bolzen 16 unter Zusammendrücken der Feder 17 und Austritt des Bolzens 16 aus der Ausnehmung 6 links oder rechts herausgepreßt.If there is a fall during the jump, the spring shoe 5 is pressed out under the two side wings 3 via bolts 16 by compressing the spring 17 and the bolt 16 exits the recess 6 on the left or right.
