Description

Die vorliegende Erfindung betrifft eine Hartschale für einen Schuh eines Rollschuhsystems und einen Schuh für das Rollschuhsystem.The present invention relates to a hard shell for a shoe of a roller skate system and a shoe for the roller skate system.

In Rollschuhsystemen sind die Schuhe als Hartschalenschuh mit einem herausnehmbaren Innenschuh oder als Soft-Boot konstruiert, bei dem nur eine halbhohe Hartschale aus festem Kunststoff gefertigt ist. Die halbhohe Hartschale des Schuhs gibt dem Fuß seitlichen Halt und ermöglicht die Befestigung des Schuhs auf einer Schiene. Allerdings schränkt diese Halbschale die Bewegungsfreiheit des Fußes ein und reduziert den Tragekomfort.In roller skate systems, the shoes are designed as a hard shell shoe with a removable inner shoe or as a soft boot, in which only a half-height hard shell is made of solid plastic. The half-height hard shell of the shoe gives the foot lateral support and enables the shoe to be attached to a rail. However, this half-shell restricts the freedom of movement of the foot and reduces wearing comfort.

Die Druckschrift US 6,112,434 betrifft eine Skate-Schuhkonstruktion. Die Skate-Schuhkonstruktion umfasst eine Schale aus flexiblem Plastik, das eine ausreichende Stabilität umfasst, um benachbarten Bereichen des Skate-Schuhs eine ausreichende Stabilität zu geben.The pamphlet U.S. 6,112,434 relates to a skate shoe construction. The skate shoe construction comprises a shell made of flexible plastic, which has sufficient stability to give sufficient stability to adjacent areas of the skate shoe.

Die Druckschrift FR 2 759 552 betrifft einen Sportschuh, insbesondere für einen Inline-Roller.The pamphlet FR 2 759 552 relates to a sports shoe, in particular for an inline roller.

Die Druckschrift GB 2 437 241 A betrifft einen Schuh, der den Träger vor Verletzungen beispielsweise beim Skaten schützt.The pamphlet GB 2 437 241 A relates to a shoe that protects the wearer from injuries, for example when skating.

Die Druckschrift US 2003/0204971 A1 betrifft einen Sportstiefel, der für Inline-Skates verwendet werden kann.The pamphlet US 2003/0204971 A1 relates to a sports boot that can be used for inline skates.

Es ist die Aufgabe der vorliegenden Erfindung ein Rollschuhsystem derart zu verbessern, dass dieses eine größere Bewegungsfreiheit für einen Fuß ermöglicht und Schmerzen beim Rollschuhfahren verringert.It is the object of the present invention to improve a roller skate system in such a way that it enables greater freedom of movement for a foot and reduces pain when roller skating.

Gemäß einem ersten Aspekt wird diese Aufgabe durch eine Hartschale für einen Schuh eines Rollschuhsystems zum seitlichen Stabilisieren eines Fußes gelöst, mit einem Sprunggelenkabschnitt zum seitlichen Umfassen eines Sprunggelenks, der eine fensterartige Öffnung im Fersenbereich des Sprunggelenkabschnitts, die auf einer Fußaußenseite der Hartschale gebildet ist; einem Fußbettabschnitt zum seitlichen Umfassen eines Fußbettes; und einer u-förmigen Aussparung zwischen dem Sprunggelenkabschnitt und dem Fußbettabschnitt. Dadurch wird beispielsweise der technische Vorteil erreicht, dass der Tragekomfort des Schuhs erhöht wird und Druckstellen am Fuß verhindert werden. Insbesondere lassen sich Schmerzen an denjenigen Stellen des Fußes vermeiden, an denen sich Überbeine bilden können. Zudem wird die Elastizität zwischen dem Fußbettabschnitt und dem Sprunggelenkabschnitt verbessert. Dadurch wird beispielsweise der technische Vorteil erreicht, dass sich Druckstellen und Schmerzen am Fuße vermeiden lassen, ohne dass eine seitliche Stützung des Sprunggelenks aufgegeben wird und sich der Tragekomfort des Schuhs erhöht.According to a first aspect, this object is achieved by a hard shell for a shoe of a roller skate system for laterally stabilizing a foot, with an ankle joint section for laterally embracing an ankle joint, which has a window-like opening in the heel area of the ankle joint section, which is formed on an outer side of the foot of the hard shell; a footbed section for laterally embracing a footbed; and a U-shaped recess between the ankle section and the footbed section. As a result, for example, the technical advantage is achieved that the wearing comfort of the shoe is increased and pressure points on the foot are prevented. In particular, pain can be avoided in those parts of the foot where over-legs can form. In addition, the elasticity between the footbed section and the ankle joint section is improved. This has the technical advantage, for example, that pressure points and pain on the foot can be avoided without giving up lateral support for the ankle and increasing the comfort of the shoe.

Mit dem Rollschuhsystem 300 ist es für einen Skater möglich, sich rollend fortzubewegen. Das Rollschuhsystem 300 umfasst eine Schiene 200 und einen Schuh 100 für den Fuß des Skaters. Fig. 1 shows a view of an inline skate as a roller skate system 300. In the roller skate system 300, the rollers 207 are arranged one behind the other in a longitudinal row (in-line). With the roller skate system 300 it is possible for a skater to move about while rolling. The roller skate system 300 comprises a rail 200 and a shoe 100 for the foot of the skater.

Die Schiene 200 dient zur Aufnahme der Rollen 207, die über Schrauben 209 an der Schiene 200 befestigt sind. Der Schuh 100 umfasst eine halbhohe Hartschale 105, die an der Unterseite ein Dreipunkt-Befestigungssystem zum Befestigen des Schuhs 100 auf der Schiene 200 aufweist. Die Hartschale 105 stützt den Fuß und das Sprunggelenk seitlich ab.The rail 200 serves to accommodate the rollers 207, which are fastened to the rail 200 by means of screws 209. The shoe 100 comprises a half-height hard shell 105, which has a three-point fastening system on the underside for fastening the shoe 100 on the rail 200. The hard shell 105 supports the foot and the ankle laterally.

Die Schiene 200 kann im Allgemeinen für die Aufnahme von zwei, drei, vier oder mehr Rollen 207 ausgelegt sein, die hintereinander angeordnet sind. Die Aufnahme der Rollen 207 kann in einer Ebene liegen oder gerockert sein, so dass sich entlang der Schiene 200 ein gebogener Verlauf ergibt (Banana Shape). Die Rollen 207 werden über ein Doppelachssystem oder Einachssystem fest in der Schiene 200 verschraubt. Die Schiene 200 kann beispielsweise Rollen 207 mit einem Durchmesser von 50 mm bis 150 mm aufnehmen. Die Schiene 200 kann aus einer Aluminiumlegierung, Magnesiumlegierung oder einem kohlenstofffaser- und/oder glasfaserverstärktem Kunststoff (Karbon oder Karbon/Fiberglas) gefertigt sein. Die Schiene 200 kann auch aus Kohlefasern oder Glasfasern gebildet sein. Die Schiene 200 kann extrudiert, gefräst, gegossen oder gestanzt gefertigt sein. Eine Schiene 200 aus Kohlefasern oder Glasfasern kann mittels eines Compression-Moulding-Verfahrens hergestellt sein.The rail 200 can generally be designed to accommodate two, three, four or more rollers 207, which are arranged one behind the other. The reception of the rollers 207 can lie in one plane or be rocked, so that a curved course results along the rail 200 (banana shape). The rollers 207 are firmly screwed into the rail 200 via a double-axis system or a single-axis system. The rail 200 can, for example, rollers 207 with a diameter of Pick up 50 mm to 150 mm. The rail 200 can be made of an aluminum alloy, magnesium alloy or a carbon fiber and / or glass fiber reinforced plastic (carbon or carbon / fiberglass). The rail 200 can also be formed from carbon fibers or glass fibers. The rail 200 can be manufactured in an extruded, milled, cast or stamped manner. A rail 200 made of carbon fibers or glass fibers can be produced by means of a compression molding process.

Der Schuh 100 ist als Soft-Boot konstruiert, bei dem nur die halbhohe Hartschale 105 aus festem Kunststoff gefertigt ist. Die Hartschale 105 des Schuhs 100 ist an drei Verbindungspunkten über Schrauben fest mit der Schiene 200 verbunden.The shoe 100 is constructed as a soft boot, in which only the half-height hard shell 105 is made of solid plastic. The hard shell 105 of the shoe 100 is firmly connected to the rail 200 at three connection points by means of screws.

Fig. 2 zeigt eine weitere Ansicht des Rollschuhsystems mit Schuh 100 und Hartschale 105. Die Hartschale 105 ist beispielsweise aus einem Kunststoff gebildet, in den zur Versteifung Glas- oder Karbonfasern eingebettet sind. Daneben kann die Hartschale 105 aus Kohlefasern oder Glasfasern oder einer Mischung beider Fasern gebildet sein. Im Allgemeinen kann die Hartschale 105 auch lediglich auf Basis eines Kunststoffes hergestellt sein. Die Hartschale 105 ist mit dem Schuh 100 verklebt und an drei Punkten mit der Schiene 200 verschraubt. Fig. 2 shows a further view of the roller skate system with shoe 100 and hard shell 105. The hard shell 105 is formed, for example, from a plastic in which glass or carbon fibers are embedded for stiffening. In addition, the hard shell 105 can be formed from carbon fibers or glass fibers or a mixture of both fibers. In general, the hard shell 105 can also be produced solely on the basis of a plastic. The hard shell 105 is glued to the shoe 100 and screwed to the rail 200 at three points.

Fig. 3 zeigt eine Ansicht der Hartschale 105. Die Hartschale 105 umfasst einen Sprunggelenkabschnitt 101 zum seitlichen Umfassen des Sprunggelenks und einen Fußbettabschnitt 103 zum seitlichen Umfassen eines Fußbettes. An der Fußinnenseite der Hartschale 105 ist eine u-förmige Aussparung 107 zwischen dem Sprunggelenkabschnitt 101 und dem Fußbettabschnitt 103 gebildet. Die u-förmige Aussparung 107 bewirkt eine Elastizität zwischen dem Fußbettabschnitt 103 und dem Sprunggelenkabschnitt 101 und erhöht den Tragekomfort des Schuhs 100. Wenn sich in diesem Bereich ein Überbein am Fuß des Fahrers befindet, übt die Hartschale in diesem Bereich keinen Druck aus. Fig. 3 shows a view of the hard shell 105. The hard shell 105 comprises an ankle joint section 101 for laterally embracing the ankle joint and a footbed section 103 for laterally embracing a footbed. On the inside of the foot of the hard shell 105, a U-shaped recess 107 is formed between the ankle joint section 101 and the footbed section 103. The U-shaped recess 107 causes a Elasticity between the footbed section 103 and the ankle joint section 101 and increases the wearing comfort of the shoe 100. If there is an over-leg on the driver's foot in this area, the hard shell does not exert any pressure in this area.

Der Rand der u-förmigen Aussparung 107 geht kontinuierlich und ohne Ecken von dem Sprunggelenkabschnitt 101 in den Fußbettabschnitt 103 über. Die Hartschale 105 kann in dem Bereich um die Aussparung 107 herum mit zusätzlichen Glasfasern oder Karbonfasern verstärkt sein, so dass ein Einreißen oder Aufbrechen der Aussparung 107 verhindert wird.The edge of the U-shaped recess 107 merges continuously and without corners from the ankle joint section 101 into the footbed section 103. The hard shell 105 can be reinforced in the area around the recess 107 with additional glass fibers or carbon fibers, so that the recess 107 is prevented from tearing or breaking open.

An der Unterseite der Hartschale 101 sind Befestigungsvorrichtungen 109 zum Befestigen des Schuh 100 an der Schiene 200 gebildet. Die Befestigungsvorrichtungen 109 können durch Öffnungen gebildet sein, in die sich Schrauben einsetzen lassen. Im Allgemeinen kann die Hartschale 101 zwei oder drei Befestigungsvorrichtungen 109 aufweisen. Insbesondere kann die Hartschale 105 ein Dreipunkt-Befestigungssystem zum Befestigen des Schuhs 100 auf der Schiene 200 umfassen. Eine erste Befestigungsvorrichtung kann in einer Mitte im Fersenbereich des Schuhs 100 angeordnet sein. Die zweite Befestigungsvorrichtung kann an einer Außenseite im Ballenbereich des Schuhs 100 angeordnet sein. Die dritte Befestigungsvorrichtung kann an einer Innenseite im Ballenbereich des Schuhs 100 angeordnet sein.Fastening devices 109 for fastening the shoe 100 to the rail 200 are formed on the underside of the hard shell 101. The fastening devices 109 can be formed by openings into which screws can be inserted. In general, the hard shell 101 may have two or three fastening devices 109. In particular, the hard shell 105 can comprise a three-point fastening system for fastening the shoe 100 on the rail 200. A first fastening device can be arranged in a center in the heel region of the shoe 100. The second fastening device can be arranged on an outside in the ball area of the shoe 100. The third fastening device can be arranged on an inner side in the ball area of the shoe 100.

Fig. 4 zeigt eine weitere Ansicht der Hartschale 105. In dem Sprunggelenkabschnitt 101 ist eine fensterartige Öffnung 111 im Fersenbereich des Schuhs 100 gebildet. Dadurch wird der Fuß im Fersenbereich von einem Druck befreit. Die Öffnung 111 befindet sich an der Fußaußenseite der Hartschale 105 und weist im Wesentlichen eine ovale Form auf. Die ovale Form erstreckt sich in vertikaler Richtung von oben nach unten im Außenbereich der Ferse. Fig. 4 shows a further view of the hard shell 105. In the ankle joint section 101, a window-like opening 111 is formed in the heel area of the shoe 100. This relieves the foot of any pressure in the heel area. The opening 111 is located on the outside of the foot of the hard shell 105 and is essentially oval in shape. The oval shape extends in the vertical direction from top to bottom in the outer area of the heel.

Die Hartschale 105 kann um die Öffnung 111 herum zusätzlich mit Glasfasern oder Karbonfasern verstärkt sein, so dass ein Ausreißen der Öffnung 111 verhindert wird. Der Rand der Öffnung 111 ist abgerundet, so dass ein Stoff des Schuhs 100 nicht durch Reibung beschädigt wird.The hard shell 105 can be additionally reinforced around the opening 111 with glass fibers or carbon fibers, so that the opening 111 is prevented from being torn out. The edge of the opening 111 is rounded so that a fabric of the shoe 100 is not damaged by friction.

Das Rollschuhsystem 300 kann für Speedskating, Inline-Hockey, Freeskating oder Fitness-Skating angepasst sein. Durch die u-förmige Aussparung 107 und die Öffnung 111 lassen sich Druckstellen und Blasen am Fuß beim Fahren verhindern. Zudem erhöht sich der Tragekomfort, da die Hartschale 105 in diesen Bereichen keinen Druck auf den Fuß ausübt. Wenn der Fuß in diesen Bereichen Überbeine aufweist, lassen sich außerdem Schmerzen reduzieren.The roller skate system 300 can be adapted for speed skating, inline hockey, freeskating or fitness skating. The U-shaped recess 107 and the opening 111 prevent pressure points and blisters on the foot when driving. In addition, the wearing comfort is increased, since the hard shell 105 does not exert any pressure on the foot in these areas. If the foot has excess legs in these areas, pain can also be reduced.

Alle in Verbindung mit einzelnen Ausführungsformen der Erfindung erläuterten und gezeigten Merkmale können in unterschiedlicher Kombination in dem erfindungsgemäßen Gegenstand vorgesehen sein, um gleichzeitig deren vorteilhafte Wirkungen zu realisieren.All features explained and shown in connection with individual embodiments of the invention can be provided in different combinations in the subject matter according to the invention in order to simultaneously realize their advantageous effects.
