Abstract

The fingerboard has an elongated platform made of wood or plastic, where an upper side of the platform is provided with a grip tape or foamed rubber. Articulately supported axles are arranged on a lower side of the platform. Connection between a base and a hanger (5) is damped by plastic damping parts. The damping parts are inserted into a recess at the base and above or below a lug of the hanger on a kingpin. A knurl is formed on a continuous axle pin. A conical cross-hole (9) is pressed in the knurl into the hanger. The recess has a notch at the base.

Description

The invention relates to a fingerboard (miniature skateboard) with which, as in skateboarding, different grind and flip tricks can be made; These are executed during fingerboarding with the middle and index fingers

It is known that fingerboards (miniature skateboards) have axes that are based on the axes of a skateboard. Basically, the fingerboard axes, as they already belong to the prior art and are found on most models, in particular the shape, d. H. the aesthetic design, based on skateboards.

The axes are connected either directly, ie by a connected device, with the fingerboard, or, the axis is fixed by means of a base, which is attached to the fingerboard, with this. The axes are thus attached either as a one-piece or two-piece device, consisting of base and hanger on the fingerboard.

The axis pin is not continuous in the previous fingerboard axes, but consists of two parts, which are each pressed into the corresponding hole on the hanger.

Also, the diameter of the axle pin and the ball bearing is not matched. In addition, the axles are not matched to ball bearing rollers. The rollers sit with their rear wall on the axle, since the diameter of the axle is larger than that of the ball bearing of the wheel.

Furthermore, steering gums, which are created twice on the kingpin, above and below the pan of the hangers, used, which offer no lateral margin.

The Hangar's Pivot sits loose and undamped in the base.

In the known versions of axes in fingerboards results in the problem that they are not suitable for a corresponding application, or the requirements that are placed on a fingerboard, not enough. The high load, in particular by performing the flip and Grindtricks ensures in the known cases that the axles wear out very quickly, at the connection points z. As the screws loose, or completely detached from the fingerboard.

The wear, as well as the looseness of the parts, especially the screws, nut, wheels and the fingerboard anchoring, destabilize the fingerboard, which in the end leads to the fact that this can not be used as intended, as well as to that the wear of the parts is relatively high.

The fact that the axle pin does not consist of a continuous part, but of two items that are pressed into the hole accordingly, the Achsstiftteile bend after a short time, for example. By applying the tricks or by exerting pressure by the finger guide. This then causes the rollers of the fingerboard no longer drive straight on the rolling surface, but slightly bent laterally downwards. This provides for an accelerated, disproportionate wear of the wheels, as well as for an unsafe, shaky handling.

Also, the diameter of the axle pins is not matched to the ball bearings of the rollers, so that the roles sit askew and / or loose. Thus, the driving behavior is deteriorated by the unclean mounted Achsstiftteile, as well as by the thus improperly seated roles. This also causes disproportionate wear of the rollers.

Furthermore, the two ends of the hanger are not tuned to the bearing rollers of the rollers, so that rubs the back of the rollers at the ends of the hangers, which deteriorates the rolling behavior as well as the overall handling of the fingerboard.

This condition is reinforced by the steering rubbers, which do not contribute to the desired driving and steering behavior due to their shape. Due to the rectilinear shape of the steering rubber harmonious steering, as well as a corresponding damping of the movement is not possible. Thus, a steering or freedom of movement by tightening the nut is hardly given; The locker of the mother increases the freedom of movement, but at the expense of the stability of the axles and thus on the entire fingerboard.

Also, the lack of cushioning of the pivot, which sits on the base, limits the steering behavior as well as the driving behavior of the fingerboard, as the pivot in the recess in the base has too much freedom of movement.

The object of the innovation is to provide an improved axle device of the specified type, on the one hand by the novel stability improves the driving and steering characteristics of the fingerboard and on the other, due to their design, allows replacement of the individual parts.

The object is achieved by a device having the features of claims 1 to 3.

The fingerboard axes described are a professional alternative to the previously available versions. Due to the improved interaction of the individual parts, the axles give the fingerboard a new kind of stability, which is best suited for fingerboard sports.

It is advantageous that now damping elements are installed, which significantly improve the steering and handling of the fingerboard. In particular, the damper, which is accommodated in the recess on the base, provides a free, yet secure and damping connection between base and hanger.

The rounded damper elements mounted on the kingpin above and below the ladle, which has a bore, of the hangar provide smoother movement of the axles for greater stability.

It is also advantageous that the damping properties can be changed by tightening or loosening the nut, without, for example, while the entire device by loosening too loose, causing the entire desired stability would be lost. Furthermore, the damping properties can be changed by varying the material.

It is also advantageous that the axle pin consists of a continuous steel pin, and not as usual from two parts. Thus, a bending, z. B. caused by pressure of the finger guide on the fingerboard surface, the individual axle parts is no longer possible, which had a misalignment of the wheels, including unnecessary friction and disproportionate wear, the result.

The axle pin and the diameter of the ball bearing are matched to each other, which also provides for a reduction in friction, as well as for a suitable interaction. This also excludes skewing of the wheels.

Also, it has not been possible to replace the individual axle parts, as they were pressed into the hole in the hanger, without any pulling out was possible, or only with disproportionate effort.

The knurl attached to the axle pin prevents the wheel from turning when the wheel nuts are tightened. Even if the axle pin is loosely seated in the transverse bore of the trailer, the axle pin is held in the center when the wheels are correctly mounted, ensuring straight and proper rolling.

Another advantage is that the two ends of the hangers have a conical shape and at the end so slim that they press only on the inner ring of the bearing of the wheels and fix it so without the wheel back is touched. Thus, an optimal grip of the wheels is made, so that they no longer have the opportunity to lie awry. In this way, unnecessary friction and a disproportionate wear of the wheels is prevented.

Another advantage is that the fingerboard axle consists of exchangeable parts. Thus, it is possible to replace one or more parts, which has hitherto not been possible due to the design. An exchange of the complete axis is thus no longer absolutely necessary.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

Fingerboards consist essentially of an elongated platform made of wood or plastic, the top is provided with a grip or Riptape. On the underside articulated axles are arranged at the end regions.

The axes consist of the base 1 and the hanger 5 which are joined together, the base 1 the axes connects to the fingerboard bottom.

The base 1 consists of four holes 2 for attachment to the fingerboard, from a recess 3 for receiving a plastic damping part 10 , in turn, a notch 4 has to rotate the plastic in the recess 3 prevent as well as from a bore 13 through which a kingpin is pressed, which is the base 1 with the hanger 5 combines.

The hanger 5 has a conical shape at both ends 6 , which at the end is so slender that the ends press on the inner ring of the bearing and fix it. The pivot 7 makes a loose connection to the base 1 ago. This will be in the recess 3 in the base 1 guided and through the plastic damper 10 secured and kept movable.

The plastic damper 12 is attached to the kingpin with the rounded side down. At the hanger 5 is a pan 8th formed with a bore, with which the hanger 5 so put on the kingpin is that the pivot 7 in the recess 3 the base 1 is inserted.

The plastic damper 11 Place with the flat side down on the kingpin, above the pan 8th of the hangers 5 , stuck. Then a disc is plugged in and a nut is screwed onto the kingpin.

The axle pin, which has a, preferably, 6 mm long knurl and two threads, is in the larger opening of the conical transverse bore 9 pressed.

The axes mounted in this way are each on the fingerboard underside, on the four holes provided for this purpose 2 on the base 1 , fastened in the end areas.

The rollers are attached to the axle pin with stop nuts, which ensure that the rollers can not slip off the axle pin.
