Definitions
- the invention relates to a gliding board, in particular a ski, according to the preamble of claim 1.
- Gleitbrett here is a snow gliding board to understand that may be in the form of conventional skis, monoski or a snowboard.
- the typical structure of a traditional gliding board is exemplified by the DE 20 2006 000 050 U1 ,
- the design of the tread in plan view and in side view is relevant for the handling behavior of the gliding board in addition to the material parameters and the course of the thickness.
- sliding boards usually have a sidecut, which in combination with the resulting deflection of the ski results in the effectively driven radius.
- the skis In the side elevation, the skis have a concave Spitzitzierbiegung, which form the blade in the front area. This is followed by a convex middle region and, in turn, a concave end bend.
- the central region or the central part has an upwardly inclined convex curvature, which merges towards the ends into the concave negative curvature, so that two points of inflection are formed here.
- the unloaded flat-lying ski in its bearing surface that is the Contact area, bounded by a rear and front contact line on the ski base towards the snow.
- the bias is defined as a curve between the lines of contact when lying flat ski on a flat documents.
- the gliding board substantially influences the control and handling characteristics of the gliding board both in terms of its length and in terms of its preload height.
- Skis are already known from the origin of skiing, which do not yet have the aforementioned shape.
- the wooden boards produced under the term "barrel pigeons" are not comparable in terms of sidecut and construction with modern skis.
- a generic sliding board is from the US 2008/042400 A1 known.
- the object of the invention is to improve the control behavior and handling of a sliding board, in particular a ski, by optimizing the contact curve, so that a lower momentum release moment is required for the swing release and that an improved sliding and floating of the ski on snow is possible.
- the contact surface of a sliding board which consists of a front part, middle part and rear part, in the unloaded state of the sliding board on a curvature, starting from a central contact line in the middle part, which has a horizontal tangent to the front and rear part of a positive curvature without turning points.
- a central contact line in the middle part which has a horizontal tangent to the front and rear part of a positive curvature without turning points.
- the upper surface of the sliding board opposite the contact surface is flat in the central part and in the front part and rear part in each case at least towards the ends.
- the concrete curve of the sliding board in use now results from the stiffness behavior, the sidecut and other constructive details of the ski.
- This design makes it easier to rotate the gliding board, especially in difficult piste conditions. It results in a higher leadership stability in solid center even if the sliding board is only slightly tilted. It is particularly advantageous that the sliding board does not have to be bent in order to achieve the lateral contact of the edges in the folded-up state. This results in less effort during skiing or snowboarding. Due to the reduced effort a neutral riding position is possible, which in turn leads to increased safety when skiing or snowboarding. By a lower overall snow resistance, a better sliding and floating of the sliding board is possible, Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
- the sliding board is advantageously laterally waisted.
- the narrowest point of the sliding board is at least 0.07 m in the middle section.
- the lateral curve of the sidecut is preferably composed of different radii. These radii are advantageously between 10 and 30 m.
- center line of contact is located in an area that extends 0.3 m in front of and behind the bond mounting point on the surface.
- FIG. 1 is the cross section of a ski 10 shown with the essential ski components.
- the ski 10 has a base in which a tread 12 of lateral metal edges, preferably steel edges 14, is limited.
- a reinforcement 16 is formed adjacent to the tread 12 in a known manner.
- the surface 18 consisting of the tread 12 and the underside of the steel edges 14 is the contact surface to the snow.
- the upper part of the ski 10 is essentially formed by a surface 20 and a top flange reinforcement 22.
- the contact surface 18 opposite, arranged at the top of the ski 10 surface is referred to as upper surface 24.
- Between the substructure and the upper part of the intermediate space is filled by means of a core material 26, which is laterally bordered by side cheeks 28 in the illustrated embodiment.
- FIG. 2 the plan view is shown, which consists of a middle part 30 a front part 32 and a rear part 34. Like from the FIG. 2 can be seen, the ski is waisted.
- the sidecut has its narrowest point bm in the middle part 30. With bh is the widest point in the ski rear part 34 and bv is the widest point in the ski portion 32 is designated.
- the waisting curve may be formed of different circle segments as shown in FIG FIG. 2 is shown with the circle segments with the radii R1 and R2.
- the sidecut can also be made from any radius. The use of a single radius would be possible.
- FIG. 2 is further indicated as BMP the so-called binding mounting point, which determines the central binding mounting position. This central binding mounting position corresponds to a common mark on the shoe sole.
- FIG. 3 can be seen from the longitudinal section of the curvature of a conventional ski 10. This results in the front part 32 a concave Spitzaufbiegung, to which a convex middle part 30 and turn a concave rear part 34 connect. In the curve of the lateral crack, two turning points thus result, which form the front contact line KPV and the rear contact line KPH. These contact lines KPV in the front part and KPH in the rear part limit the contact surface of the entire ski. With hv is in the FIG. 3 denotes the maximum preload.
- the respective ski thickness which is also responsible for the stiffness of the ski, results from the distance between the contact surface 18 and the surface 24.
- the contact lines KPV and KPH are also in the FIG. 2 drawn in dashed lines. Between these contact points is formed in free-lying flat ski the Bias curve off. This is greatest in the middle range between the contact lines KPV and KPH, as in FIG. 3 indicated by the maximum bias HV.
- the contact surface 18 of the unloaded ski 10 has a curvature course, starting from a central contact line KL in the middle part, which has a horizontal tangent, respectively to the front 32 and rear 34 a positive curvature without turning points having.

Description
Die Erfindung betrifft ein Gleitbrett, insbesondere einen Ski, nach dem Oberbegriff des Anspruchs 1.The invention relates to a gliding board, in particular a ski, according to the preamble of claim 1.
Unter Gleitbrett ist hier ein Schneegleitbrett zu verstehen, das in Form von konventionellen Ski, Monoski oder eines Snowboards ausgeführt sein kann.Under Gleitbrett here is a snow gliding board to understand that may be in the form of conventional skis, monoski or a snowboard.
Der typische Aufbau eines traditionellen Gleitbretts ergibt sich beispielhaft aus der
Beim Carven, wenn das Gleitbrett also auf die Kante gestellt durch die Kurve geleitet wird, deformiert es sich im mittleren Bereich in Folge der auftretenden Belastungen elastisch, so daß aus der ursprünglich konvexen Krümmung, temporär eine konkave Krümmung wird. Als Überlagerung des sich in Folge der Belastung einstellenden Deformationszustandes, der seitlichen Taillierung und dem Aufkantwinkel (das heißt dem Winkel zwischen der Gleitfläche und dem Untergrund für den Fall, daß das Gleitbrett auf die Kante gestellt ist) beschreibt die auf dem Untergrund aufliegende Seitenkante eine im wesentlichen kreisförmige Bahn, die im Idealfall der zu fahrenden Kurve entspricht.When carving, when the sliding board is thus placed on the edge through the curve, it deforms elastically in the central region as a result of the loads occurring, so that from the originally convex curvature, temporarily becomes a concave curvature. As a superposition of the resulting as a result of the load deformation state, the lateral sidecut and the Aufkantwinkel (that is, the angle between the sliding surface and the ground in the event that the sliding board is placed on the edge) describes the resting on the ground side edge in the essentially circular path, which in the ideal case corresponds to the curve to be traveled.
Das Gleitbrett beeinflußt unabhängig von der Taillierung und den mechanischen Eigenschaften des Skikontaktbereichs sowohl in seiner Länge als auch in seiner Vorspannungshöhe das Steuer- und Fahrverhalten des Gleitbretts wesentlich.Regardless of the waisting and the mechanical properties of the ski contact area, the gliding board substantially influences the control and handling characteristics of the gliding board both in terms of its length and in terms of its preload height.
Auch aus der
Aus der
Schließlich ergibt sich auch aus der
Aus dem Ursprung des Skilaufs sind auch schon Ski bekannt, die die vorgenannte Formgebung noch nicht aufweisen. Die unter dem Begriff "Fasstauben" hergestellten Holzbretter sind jedoch in der Taillierung und im Aufbau mit modernen Ski nicht vergleichbar.Skis are already known from the origin of skiing, which do not yet have the aforementioned shape. However, the wooden boards produced under the term "barrel pigeons" are not comparable in terms of sidecut and construction with modern skis.
Ein gattungsgemäßes Gleitbrett ist aus der
Das Ziel der Erfindung ist es, das Einsteuerverhalten und Fahrverhalten eines Gleitbretts, insbesondere eines Ski, durch Optimierung der Kontaktkurve zu verbessern, so daß zur Schwungauslösung ein geringeres Schwungauslösemoment benötigt wird und daß ein verbessertes Gleiten und Schweben des Ski auf Schnee ermöglicht wird.The object of the invention is to improve the control behavior and handling of a sliding board, in particular a ski, by optimizing the contact curve, so that a lower momentum release moment is required for the swing release and that an improved sliding and floating of the ski on snow is possible.
Erfindungsgemäß wird das vorgenannte Ziel durch einen Ski mit den Merkmalen des Anspruchs 1 gelöst.According to the invention, the aforementioned object is achieved by a ski having the features of claim 1.
Demnach weist die Kontaktfläche eines Gleitbretts, welches aus einem Vorderteil, Mittelteil und Hinterteil besteht, im unbelasteten Zustand des Gleitbretts einen Krümmungsverlauf auf, der ausgehend von einer zentralen Kontaktlinie im Mittelteil, welche eine waagerechte Tangente aufweist, jeweils zum Vorder- und Hinterteil eine positive Krümmung ohne Wendepunkte aufweist. Hierdurch wird also eine bogenförmige, positive Krümmungskurve der unteren Kontaktfläche des Gleitbretts erzielt. Die aus dem Stand der Technik bekannten Kontaktlinien verschieben sich dadurch zu einer einzigen zentralen Kontaktlinie im Bindungsmontagebereich. Der Verlauf kann durch eine sogenannte stetige Splinekurve bestehend aus unterschiedlichen Kurven ohne Wendepunkt mit einer waagerechten Tangente im Bereich der zentralen Kontaktlinie beschrieben werden.Accordingly, the contact surface of a sliding board, which consists of a front part, middle part and rear part, in the unloaded state of the sliding board on a curvature, starting from a central contact line in the middle part, which has a horizontal tangent to the front and rear part of a positive curvature without turning points. As a result, therefore, an arcuate, positive curvature curve of the lower contact surface of the sliding board is achieved. The contact lines known from the prior art thereby shift to a single central contact line in the binding mounting area. The course can be described by a so-called continuous spline curve consisting of different curves without inflection point with a horizontal tangent in the region of the central contact line.
Erfindungsgemäß ist die der Kontaktfläche gegenüberliegende Oberseite des Gleitbretts im Mittelteil flach auszubilden und im Vorderteil und Hinterteil jeweils zumindest zu den Enden hin zu krümmen. Hierdurch ergibt sich im Bindungsmontagebereich eine zusätzliche Verstärkung, die vergleichsweise dicker ausgeführt ist. Damit wird ein harmonischer Kantendruck insbesondere im Bindungsmontagebereich erzielt.According to the invention, the upper surface of the sliding board opposite the contact surface is flat in the central part and in the front part and rear part in each case at least towards the ends. This results in the binding mounting area an additional gain that is made comparatively thicker. Thus, a harmonious edge pressure is achieved especially in the binding mounting area.
Der konkrete Kurvenverlauf des Gleitbretts im Einsatz ergibt sich nun aus dem Steifigkeitsverhalten, der Taillierung und anderen konstruktiven Details des Skis. Durch diese Konstruktion kann eine leichtere Drehbarkeit des Gleitbretts speziell bei schwierigen Pistenverhältnissen erzielt werden. Es ergibt sich eine höhere Führungsstabilität bei massiverem Mittelbau selbst dann, wenn das Gleitbrett nur leicht aufgekantet wird.
Besonders vorteilhaft ist es, daß das Gleitbrett nicht durchgebogen werden muß, um den seitlichen Kontakt der Kanten im aufgekanteten Zustand zu erreichen. Hierdurch ergibt sich ein geringerer Kraftaufwand während des Skilaufs bzw. dem Snowboarden. Aufgrund des geringeren Kraftaufwandes ist eine neutrale Fahrposition möglich, was wiederum zu einer erhöhten Sicherheit beim Skifahren bzw. Snowboarden führt. Durch einen insgesamt geringeren Schneewiderstand ist ein besseres Gleiten und Schweben des Gleitbrettes möglich,
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.
Demnach ist das Gleitbrett vorteilhaft seitlich tailliert. Die schmalste Stelle des Gleitbretts beträgt im Mittelteil mindestens 0,07 m. Die seitliche Kurve der Taillierung ist bevorzugt aus unterschiedlichen Radien zusammengesetzt. Diese Radien betragen vorteilhaft zwischen 10 und 30 m.The concrete curve of the sliding board in use now results from the stiffness behavior, the sidecut and other constructive details of the ski. This design makes it easier to rotate the gliding board, especially in difficult piste conditions. It results in a higher leadership stability in solid center even if the sliding board is only slightly tilted.
It is particularly advantageous that the sliding board does not have to be bent in order to achieve the lateral contact of the edges in the folded-up state. This results in less effort during skiing or snowboarding. Due to the reduced effort a neutral riding position is possible, which in turn leads to increased safety when skiing or snowboarding. By a lower overall snow resistance, a better sliding and floating of the sliding board is possible,
Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
Accordingly, the sliding board is advantageously laterally waisted. The narrowest point of the sliding board is at least 0.07 m in the middle section. The lateral curve of the sidecut is preferably composed of different radii. These radii are advantageously between 10 and 30 m.
Schließlich ist die zentrale Kontaktlinie in einem Bereich angeordnet, der sich 0,3 m vor und hinter dem Bindungsmontagepunkt auf der Oberfläche erstreckt.Finally, the center line of contact is located in an area that extends 0.3 m in front of and behind the bond mounting point on the surface.
