Field of the invention

The present invention relates to a longboard and a skateboard for training purposes.

Moreover, the present invention relates to a method for equipping a longboard and a skateboard for training purposes.

State of the art

The cited prior art is incorporated by reference in the present application.

Skateboards are common and well known. Longboards are a kind of an enlarged form of skateboard and were originally developed from surfboards because the surfers wanted to transfer the feeling of surfing to the streets (Sidewalk Surfing ', Jan & Dean on The Little Old Lady from Pasadena, Liberty Records, 60's) years).

Longboards are distributed with a variety of outlines. Exemplary is the American design patents US Pat. No. D629,859 p . US D556,283 p or the American patent US Pat. No. 8,550,480 B1 directed. Longboards can also be equipped with electric motors and sensors, as in the American patent application US 2017/0007910 A1 is described. From the American patent application US 2015/0130156 A1 and the American design patent US D764,001 p is a longboard with a special suspension known. The American design patent US D757,873 S shows an advantageous embodiment of a longboard wheel.

From the US patent application US 2016/583 A1 is a "bikeboard" that combines the characteristics of a bicycle with front wheel and handlebars with a longboard board with two rear wheels. It is not clear what particular advantage this design should offer. In any case, it is not suitable for training purposes.

The handling of a longboard or a skateboard requires a very good sense of balance and a lot of practice, as the board or board and the four wheels can move simultaneously in several different directions of the room. It is therefore desirable to have a longboard or a skateboard for training purposes, so that a beginner gains a feeling for the device more easily and quickly, and after a short exercise time, masters the longboard or the skateboard safely.

According to the invention this object is achieved by the longboard or the skateboard according to the main claim. Advantageous embodiments will become apparent from the dependent claims.

The longboard or skateboard of the invention may be a minicruiser, a classic longboard (cruiser or carver), a pintail longboard or a dropthrough longboard. His longboard board, which has a top and bottom, can be flexible or not flexible. Most of the longboards and skateboards are constructed of horizontal wood or vertically laminated bamboo (called VLAM). In addition, other VLAM combinations exist, for example, from aspen and mahogany. The longboard or skateboard board can also be reinforced by appropriately aligned fiber-plastic composites.

Usually, the longboard or skateboard boards are decorative painted or painted. There are also decorative films into consideration. The top can also be non-slip.

The longboard or skateboard according to the invention has on the underside of the longboard or skateboard board in each case a Radachsenaufhängung in the region of the ends of the longitudinal axis of the underside with two front wheels and two rear wheels, which are independently movable in different directions of the room. The wheel axle suspensions also allow lateral tilting of the longboard or skateboard board. This is for example by the 8th US Patent Application US 2015/0130156 A1, which also discloses suitable wheel axle suspensions.

In a first embodiment, the longboard and skateboard according to the invention have at least one first attachment plate arranged centrally in the region of at least one end of the longitudinal axis of the upper side. Preferably, the longboard or skateboard according to the invention in the region of the two ends of the longitudinal axis each have a centrally disposed first mounting plate. On the first mounting plate or on one of the two first mounting plates, a second mounting plate is arranged congruently.

In a second embodiment, the longboard or skateboard according to the invention has at least one first attachment plate arranged centrally in the region of at least one end of the longitudinal axis of the underside. Preferably, the longboard and skateboard invention also in this embodiment in the region of the two ends of the longitudinal axis each have a center arranged first mounting plate. About the first mounting plate or on one of the two first mounting plates, a second mounting plate is arranged congruently on the top.

The embodiment with two first mounting plates offers the advantage that the holding device to be used according to the invention can be alternately fastened to two points of the longboard or skateboard board.

The mounting plates may be square, rectangular, round, oval, rectangular or square with a rounded edge and / or with rounded corners.

In the second embodiment, it may be an integral part of the wheel axle suspensions.

For a given longboard or skateboard both alternatives can be realized.

Through each mounting plate and from the top to the bottom of the longboard board at least four, in particular four, through holes are arranged with or without internal thread. The holes through the mounting plates and the longboard or skateboard board each have a common longitudinal axis. Fixing screws with a complementary screw thread are screwed into the drill holes and fastened permanently detachable with fixing nuts. The fastening nuts can be underlaid with washers.

If the mounting plates are to be permanently connected, the fastening nuts can be glued or welded to the mounting screws. Alternatively or additionally, the screw heads may be glued or welded to the second mounting plate.

In principle, every type of nut is suitable for fastening nuts. Examples of suitable fastening nuts are hexagon nuts, square nuts, lug nuts, cap nuts, self-locking nuts, castle nuts and wing nuts. They can have right or left hand threads.

In principle, every type of screw is suitable for fastening screws. Examples of suitable fastening screws are screws with hexagonal, cylindrical, countersunk, round and Linsenkopf head shapes. They can have right or left hand threads.

The mounting plates, mounting screws and fastening nuts consist of conventional and known materials, in particular of glass fiber or carbon fiber reinforced plastics or metals, in particular steel, brass and other non-ferrous alloys, titanium and aluminum.

On the second mounting plate is permanently or releasably secured a fixed, vertically or in the direction of travel forward inclined or curved holding device. At its upper end a crossbar with two terminally arranged handles is centrally permanently or detachably attached.

The vertical or in the direction of travel forward inclined or curved holding device may be rigid, adjustable in height, angle adjustable and / or foldable. For these purposes, conventional and known devices can be used, as they are known for example from collapsible bicycles or scooters.

The holding device is welded to the second mounting plate, screwed or infected. If the holder is to be detached again, it is screwed or infected. These conventional and known screw, Bayonettverbindungen or connectors can be used.

The holding device can be present in different embodiments.

So it can be a rigid, straight or bent tube.

It may consist of at least two, in particular two, arranged one above the other, formed by at least one, in particular one, conventional and known joint or a conventional and known folding device and / or folding device interconnected, straight or curved tubes.

In the case of a height-adjustable holding device, this can be formed from at least two, in particular two, telescoped, straight tubes and have at least one, in particular one, fixing device for fixing a selected height position. Examples of suitable locking devices are clamps or devices, as used for example in height-adjustable crutches.

At the upper end of the holding device a cross bar is permanently or removably attached. For attachment devices can be used with advantage, as they are used in bicycle handlebars. The crossbar has the form of a fixed or adjustable, straight or curved bicycle handlebar. At both ends is each arranged a handle. Preferably, the handle is ergonomically shaped. The crossbar may also have pads on which the forearms can be stored.

The longboard according to the invention can be painted in different colors, painted or decorated with ornaments. It is ideal as a training device for safe driving with a longboard.

Another advantage of the longboard according to the invention and the skateboard according to the invention is that it can be produced in a simple manner from a conventional and well-known longboard and skateboard. Preferably, the holding device and the crossbar are made of wood, metal, plastic, reinforced plastic and / or bonded at least built up two of these materials.

It is understood that the features mentioned above and explained in more detail below can be used not only in the specified combinations and configurations, but also in other combinations and configurations or in isolation, without departing from the scope of the present invention.
