Suomi- Finland (Pl) .. (? U) Pauli Kinnarinen (5U) Ski device for the application of a wheeled vehicle for use in winter conditions - Skidding for the use of a wheeled vehicle for winter use

The invention relates to a ski device for adapting a wheeled vehicle for use in winter conditions, in particular with regard to lightweight two-axle, towed or pushed carriages and prams, such as prams.

A wide variety of devices of this type are already known, such as, for example, shoes mounted under the wheels of a trolley and the two-legged solution disclosed in patent CH 248128 and the solution according to patent FI 23392.

The former patent is a two-legged, technically easily damaged guide roller and belts, which is not suitable for winter use in the snow.

The latter solution is simple, but the transfer of the height of the ski by hand with a screw attachment at the ground limit, in the snow base and in the frost is difficult and the grip of the attachment is uncertain.

The object of the present invention is therefore to remedy these drawbacks by means of a novel construction, and the features characteristic of the ski device according to the invention appear from the appended claim.

Claims (2)

2 57374 The use of the device according to the invention then becomes very easy when, for example, snow or ice makes it difficult for the carriages to travel, the carriages can be placed on the ski-like foot, which descends e.g. at the bottom of the wheels or even lower, e.g. when driving in deep snow. On the snow-free road section, lifting the Jalas is simply done by pressing the lever of the locking device with your foot, whereupon the spring pulls the Jalas up. The ski device can be adapted to carriages with different wheelbases, and the device can be fastened and detached from the carriages quickly when the fastening members are provided with wing nuts and / or hexagon socket screws. The ski-like, wide Leg according to the invention is almost imperceptible in the rest position, the external dimensions of the trolley are preserved. The foot is load-bearing in the snow, safe to use and easy to steer. An embodiment of the invention for prams is described in more detail below with reference to the accompanying drawing, in which Fig. 1 shows a ski device according to the invention in a mounted side view and provided with one leg and Fig. 2 a section II-II from Fig. 1. The drawing shows 1 longitudinal support beam 2, 2 of which are adjustable in the direction of the beam, are fixed to the axles of the carriage in the middle. Attached to the support beam 1 by parallel articulated arms 3 is a wider ski-like leg 5 which, by means of a tension spring 4, remains in its elevated position and which presses the adjusting rod 7 by pressing the release lever, it is released by rising with the Leg 5 to the upper position pulled by the spring 4. The invention is not limited to the embodiment shown but can be applied in various ways within the scope of the following claim. The claim 1. A ski device for the use of a wheeled vehicle for use in winter conditions, in particular for light two-axle, towed or pushed wagons and pushchairs, such as prams, as a simple structure fixed to the axles of the wagon.
