Combined scooter for running and braking on ice and snow

The invention relates to two different runner inserts (3, 4, 6, 7) and a brake insert (13, 15, 16) for converting commercially available scooters into several variable ice and snow gliders, whereby the runners of the ice gliders have characteristics characteristic of ice skates and the runners of the snow gliders have characteristics characteristic of skis. The state of the art is that the scooters are equipped with two rollers in the longitudinal direction or optionally with three rollers (where the pair at the front is equipped in parallel). Other possible variations for moving a scooter on ice or snow are not known. The disadvantage is that the commercially available scooters are only suitable for running on solid ground with rollers.

The invention is therefore based on the object of integrating the combination of runner inserts and brake inserts into commercially available scooters in such a way that, if necessary, gliding and braking on ice or snow is also possible with scooters, so that in this way the multiple use of such a sports device can be achieved.

These problems are solved by the measures of claims 1-5 in that, using the respective existing substructure of common scooters, the runner insert adapters

(1) are designed so that the necessary bores of the bearings (5) correspond to the diameter and distance of the existing roller axle bolts (9, 10). The width of the runner insert adapter (1) also corresponds to the design for the rollers of the substructure. The adapter is grooved in the middle on the underside for the form-fitting reception of equivalently designed support rails

(2) by means of a screw clamp, whereby a firm connection can be made by additional frictional connection, e.g. welding, shrinking, gluing, etc. Depending on the shape selected for holding the ice or snow runners, the support rails can have different shapes, whereby the tongue and groove connection can be, for example, straight, round, conical or polygonal.

The invention makes it possible to replace the standard rollers of the scooters with corresponding runners (3, 4, 6, 7) or sliding inserts without great effort. The ice and snow runners can be designed in one or more parts in the longitudinal direction, and can be arranged in one or more tracks in the axial direction. The runner inserts can therefore be used independently of the numerous manufacturers of scooters.

The invention is particularly advantageous for use by children, who do not have to do without their scooters regardless of the season.

The runner insert adapters (1) for snow and ice shown in Fig. 1.1 and 1.2 as well as Fig. 2.1 and 2.2 are provided with a bore, a slot or bearing (5) which are mounted using the original roller bolt axles (9,10) instead of the running wheels. The width of the
Skid insert adapter corresponds to the width of the rollers.

In the middle of the underside is a groove (tongue and groove) analogous to the shape or
force-fitting mounting rail (2), which in turn holds the snow or ice runners by means of a form-fitting or force-fitting connection.

If the commercially available scooter is converted for winter use according to Fig. 1.1-1.5 and Fig. 2.1-2.5, only the roller bolt axles (9,10) of the front and rear wheels have to be loosened and the rollers replaced with the corresponding inserts using the original bolts or spacer sleeves.

Now the corresponding runners can be mounted.

The same applies to the brake according to Fig. 3.1- 3.3, where only the brake axle (11) is released and the corresponding snow (15) or ice brake (16) is mounted with the original brake axle (11) and the original return spring (12).
