DE102004017997A1 - Sliding vehicle for leisure and sport has sliding surface of skid consisting of sliding film forming material - Google Patents

Abstract

The sliding vehicle consists of at least one ground sliding skid. The sliding surface of the skid consists of a sliding film forming material. The friction occurring during sliding over the ground melts the material due to the surface pressure acting on it. This produces a sliding film which provides a sliding capability between the ground and the skid.

Description

The The invention relates to a floor sliding vehicle, in particular for use as sports and leisure equipment, according to the preamble of claim 1.

Out The prior art ground gliding vehicles are known for snowing over or ice-covered ground, for example toboggans, Snowboards, alpine skis or nordic (cross-country) skis.

One fundamental Disadvantage of this floor sliding is the unconditional presence a lubricious Subsurface.

Without Snow-covered or ice-covered ground are the ground gliding vehicles not usable.

• • Zum Einen führt das zu einer zeitlich stark eingeschränkten Nutzung der Bodengleitfahrzeuge, da für das Vorhandensein von Schnee nicht ganzjährig die nötigen klimatischen Bedingungen vorliegen.
• • Zum Anderen führt das zu einer Abhängigkeit von schneesicheren Orten. An Orten mit geringem Schneefall ist die Nutzung der Bodengleitfahrzeuge nur in Einzelfällen möglich.

This results in further disadvantages:

• • On the one hand, this leads to a time-limited use of ground gliding vehicles, since the presence of snow does not provide the necessary climatic conditions throughout the year.
• • On the other hand, this leads to a dependence on snow-sure places. In places with low snowfall, the use of ground gliding vehicles is only possible in isolated cases.

Various approaches are known to circumvent this problem:
The prior art are skateboards, which solve the problem of usability of gliding boards in case of lack of snow by the underside attachment of wheels or rollers, such as grassboards or mountainboards.

• • Fahren mittels Räder oder Rollen folgt immer einer vorgegebenen Richtung. Das heißt, es ist nur eine einachsige Bewegung, mit einem Freiheitsgrad in X-Richtung, möglich. Ein wesentliches Merkmal von gleitender, Forbewegung, wie sie bei Rodelschlitten oder Snowboards vorliegt, ist aber die uneingeschränkte Drehbarkeit des Fahrzeuges aus der Fahrrichtung heraus, mit Bewegungsmöglichkeiten in zwei Freiheitsgraden, zum Beispiel bei Kurvenfahren. Das fehlen von weiteren Freiheitsgraden bei Fahrzeugen mit Rädern, zeigt sich zum Beispiel beim „Radieren" in Kurvenfahrten, dass auftritt, wenn die Räder quer zur Rollrichtung verschoben werden.
• • Fahren mittels Rädern oder Rollen benötigt einen Lenkmechanismus. Dieser ist in der Herstellung relativ aufwendig und teuer und im Betrieb relativ pflegebedürftig.
• • Räder, Rollen und deren Aufhängungen sind als mechanische Teile relativ aufwendig, teuer und pflegebedürftig, gerade wenn sie im offenen Gelände starken Verschmutzungen ausgesetzt sind.

In these vehicles, there are significant disadvantages with respect to known sliding boards:

• • Driving with wheels or rollers always follows a given direction. That is, it is possible only a uniaxial motion, with one degree of freedom in the X direction. An essential feature of sliding, Forbewegung, as is present in toboggans or snowboards, but is the unrestricted rotation of the vehicle from the direction of travel, with possibilities of movement in two degrees of freedom, for example when cornering. The lack of further degrees of freedom in vehicles with wheels, is shown for example when "erasing" in cornering, that occurs when the wheels are moved transversely to the rolling direction.
• • Riding by wheels or rollers requires a steering mechanism. This is relatively expensive to manufacture and expensive and in operation relatively dependent on care.
• • Wheels, castors and their suspensions, as mechanical parts, are relatively expensive, expensive and in need of care, especially when exposed to heavy soiling in open terrain.

task the new invention is to provide a ground gliding which is usable on snow- and ice-free ground and that the driving style, the driving experience and the characteristics of sliding locomotion on snow and Transferring ice to a different surface and making it tangible there.

• • Die Unabhängigkeit der Nutzung des Bodengleitfahrzeuges von schnee- oder eisbedecktem Untergrund.
• • Regelmäßiges Nutzen von Bodengleitfahrzeugen an Zeiten und an Orten, an denen es bisher durch fehlende Konstanz der Bodenbeschaffenheit (zum Beispiel Schneemangel) nicht möglich war.
• • Ein weiterführender Vorteil ist das Nutzbarmachen der bestehenden Infrastruktur in Ski- und Wintersportgebieten, wie zum Beispiel Lifte, Pisten und Unterkünfte für Anwender, zu Zeiten von Schneemangel, in denen diese Anlagen weitgehend brach liegen.
• • Keine Spurbindung wie bei Lösungen der Fortbewegung mittels Rädern oder Rollen.
• Durch das verwendete Prinzip des Gleitens über den Untergrund ist eine Bewegung in zwei Freiheitsgraden, in X- und Y-Richtung, möglich. So wird eine uneingeschränkte Drehbarkeit aus der Fahrtrichtung, zum Beispiel bei Kurvenfahrten, machbar.
• • Durch die geringe Verwendung von mechanischen Teilen, wie Räder oder Gelenke, wird eine einfache Konstruktion zum Erfüllen der Aufgabe bereitgestellt.

By solving the task, there are some advantages:

• • The independence of the use of the ground gliding vehicle from snow or ice covered ground.
• • Regular use of ground gliding vehicles at times and in places where it was previously not possible due to the lack of constancy of the soil condition (for example lack of snow).
• • A further advantage is the use of existing infrastructure in ski and winter sports areas, such as lifts, slopes and accommodation for users, during periods of lack of snow, where these facilities are largely fallow.
• • No track binding as with solutions of locomotion by means of wheels or rollers.
• The principle of sliding over the ground allows movement in two degrees of freedom, in the X and Y directions. Thus, an unrestricted rotation from the direction of travel, for example when cornering, feasible.
• • The limited use of mechanical parts, such as wheels or joints, provides a simple design to accomplish the task.

Description:

The The invention relates to a floor sliding vehicle, in particular for use as sports and leisure equipment, to glide over a background.

The Floor gliding vehicle consists of one or more floor sliding skids. The sliding surface the Bodengleitkufe consists of a film-forming material, that the lubricity of the floor sliding vehicle between the ground and Bodengleitkufe guaranteed.

Specifically, ice, consisting of water, is proposed as the film-forming material. which melts when sliding over the ground and thereby forms a sliding film for sliding movement.

the Water for the ice can also be added additives which the melting properties of the Ice for favorably influence the use of the ground gliding vehicle.

Of course you can the film-forming material also made of a different material than the consist of above-mentioned ice, for example, paraffin or wax mixtures.

The Floor sliding skids are available in different training variants:

Version 1:

The Bodengleitkufe, consisting of sliding surface and support element, is in one component united and consists of the film-forming material.

in this connection can be introduced into the Bodengleitkufe a reinforcement insert, the for dimensional stability contributes to the skid. The probation deployment is, for example, a metal grid or wire basket inserted in the gleitfilmbildende material is frozen or poured so that a breakage of the runner or the material is prevented.

This can also be made of plastic or wood.

Variant 2:

The Bodengleitkufe is not united in one component and the sliding surface and consist of the support element made of different materials.

The Connection between the material of the sliding surface and the carrier element can have a reinforcement done, which firmly with the carrier element is connected and in the material of the sliding surface, for example by pouring or Freezing, is embedded.

The sliding surface and the carrier element can but also be directly connected, for example by means of a screw connection.

The Connection between the material of the sliding surface and the carrier element Can also be used as a detachable Connection be formed so that the parts as often as possible with each other connected and detached from each other can be.

To Variant 2, there are other training possibilities of Bodengleitkufe, in which the carrier element over the pure support function assumes additional tasks:

Variant 2a:

When additional Task of the carrier element is provided here that the support element on the material of the sliding surface cooling acts to be too fast in warm soil or ambient temperatures To prevent melting of the material of the sliding surface.

This is achieved by a cold storage, which is filled with a low-temperature cooling material, for example, liquid N ₂ , or by a cooling device. These cooling elements may be mounted on or under the support member or integrated therein.

The Material and the shape of the support element can hereby so be it as a heat absorber for that too cooling Material acts.

The Floor sliding skid has in the front area and at the end, similar to a snowboard, a slight curvature or bevel away from the ground, to prevent penetration of the skid into the ground.

to Accident-free use of the ground gliding vehicle is on the top the carrier element an area made of non-slip and possibly heat-insulating Material attached to it during the Driving, sitting or lying.

Also is it possible in principle to attach a seat to the floor sliding vehicle.

Farther can one or more brakes installed on the ground glide vehicle be which for reducing the driving speed or the Steering can be used.

Farther can on the ground glide handles for holding during the Ride or be secured for transport.

Farther The floor gliding vehicle can be provided with a special binding be that allow a secure fixing of shoes on this.

• • für allgemein gebräuchliche Schuhe oder spezielle sportartspezifische Schuhe gefertigt sein.
• • als unverschiebliche Bindung oder in ihrer Halterung verdreh- und verstellbare Bindung ausgebildet sein.
• • als Bindung mit Klappschahnieren ausgebildet sein, die eine Nutzung wie bei Langlaufskiern ermöglichen.
