Roller board

The present masonry relates to a roller board, consisting consisting of a base plate and two axle carriers, each of which carries a pair of rollers, which are arranged at a distance from one another on the underside of the stami plate, the base plate being made of plastic and a has ribbing.

Ss a roller board has become known in which the elongated, elastic and completely injection-molded polypropylene base is engraved or ribbed on the surface and thickened in a bulbous manner at the rear end, and

on the underside rectangular recesses of various sizes (DE-OM 7 627 6rj). In this known roller board 1st the base plate is flat on the underside with the exception of the recesses, that is, designed as a straight line. This execution has the disadvantage that the base plate tilts over a pair of rollers when driving the dfts roller board from the driver is, comes with its underside in contact with the road, whereby the roller board is braked. The grazing Curses are damaged and affected in a very short time the strength properties of the stand area flow as a result very unfavorable, quite apart from the fact that the appearance of the roller board suffers from it. Because of going in different directions running ribbing of the entire top and bottom of the Stand plate is the injection molding tool for making the stand plate extremely complicated and also the flow of material becomes very much hindered when spraying, so that it is too nioht from the material-filled areas (Lankeratsllen) can kessen.

The task of the present innovation is to use a roller board to create a steel plate made of plastic that is more universal,

SO d. H. can also be used for figure driving without that Parts wear out quickly and become unsanitary, and its Stand plate can be manufactured with simpler tools and without the risk of blowholes when spraying. Furthermore the top board should provide great security against slipping

Driver's offer.

These tasks are solved by the features described in the protection claim.

By unwinding the two, you can find the stand plate · from the

Road away upwards is on the one hand the tilt angle of the Board (by a pair of rollers) enlarged and on the other hand the Reduced risk that the underside of the base plate comes into contact with the road when the figure is approached, and so on nit slows down the roller board. At the same time, this Ab winke lunge η created a roller board with two kick-tails, through which the target board is even better when riding hairstyles can be maneuvered. The angle of inclination of the angled ends is expediently different out, and this is advantageous at the rear end larger than at the front end of the base.

The arrangement of the stiffening ribs on the underside essentially only in one direction, preferably in the Longitudinal direction of the base plate, on the one hand, are cheaper Strength properties and, on the other hand, simpler tool forums and a more favorable material flow of the material Splashing the board achieved. This is particularly advantageous if, for. B. a glass fiber reinforced plastic as Material is used for the base plate. To the last

So-called advantages also contribute to the fact that the top of the base plate is only in the area of the front and rear Xndes is provided with a roughened surface, while the middle area is made smooth. As a slip-proof The pattern is a honeycomb pattern for the roughened surface seen.

As a further safeguard against slipping off the driver's feet the base plate is provided with a raised edge on the top of the outer catch bit.

Further details of the innovation solion based on the

In Figures 2 to 5, the base plate 1 is shown in different views and sections. On the upper side 12 of the base plate 1 la only region of the front and rear end provided with a roughened surface 13 a honeycomb pattern Ik is present, while the surface in the central region of the top 12 is formed smooth. On the upper side 12 in the area of the outer circumference a, the base plate is provided with a raised, all-round band 15, which prevents the driver's feet from slipping off.

On the underside 16, the base plate is essentially only provided with stiffening ribs 17 running in the longitudinal direction. Only in the area of the fastening surfaces for the base plates 8 and at the kink of the bends on the front 9 or rear end 10, transverse stiffening ribs 18 are provided. The attachment of the base plates 8 with the axle beams 2 or 3 on egg stand plate 1 takes place in a known manner by arranged in the bores 19 in the base plate 1 Screws (see Fig. 1).

The innovation is not limited to the embodiment described above limited. In the context of the innovation concept, constructive changes are still possible, which are not listed in more detail will.
