The invention relates to a pedal device from

• r

Relatively simple figure on which a Person can balance himself and which is operated by pedaling in such a way that the person himself on the floor, either for pastime and amusement and / or for physical exercise can move "

The device preferably has three wheels arranged next to one another in parallel planes in such a way that

Class they have a common axis »The wheels are connected to one another by two parallel axle links, «could extend at right angles to the planes of the wheels and are arranged eccentrically with respect to the common wheel axle. The individual axle links extend between the central wheel and one of the two outer wheels, furthermore the connection points of the Axle links with the center wheel lie on a diameter of this wheel and are arranged at the same distance from the center. sincU

The wheels themselves can be solid wheels or spoked wheels. They can be made of wood, metal or any other suitable Material and be covered with pads or tires made of rubber or another material that is in is usually arranged on the wheels *

The axle links can have a one-piece structure or from parts: to be composed. Ira the latter Pail the individual axle links from a wooden or Metal shafts exist at their ends "in corresponding X & tops of the wheels between which the axle is located extends »is held. At an intermediate part can then

In the following, a preferred embodiment of the invention is described in more detail with reference to the drawing. Further features of the invention emerge from the description and drawing. In the drawing:

Fig.l is a front view of the device; 2 shows an end view of the device, specifically in

ifig.l seen to linka;
Pig. 3 shows a partial section along the line III-III in

Pig.2 seen in the direction of the arrows and Fig.4 a partial section along line IV-IV of Fig.l

The device shown in the drawings has three Wheels 1, which are formed from solid wooden discs of the same diameter. The wheels have on their circumference Grooves of semicircular shape, in. The tires .2 made of rubber or other suitable material, for example elastomeric plastic material, or also a appropriate rope are inserted. The wheels 1 are arranged side by side in parallel planes so that they

have a common axis 3. They are through with each other two short axle links 4 connected, one of which is between the center wheel and the one outer wheel and that the other extends between the central wheel and the other outer wheel. The axle links 4 are for Axis 3 of the wheels 1 arranged eccentrically. They run away parallel to axis 3 at equal distances from it. The connection points of the axle links 4 with the center wheel are arranged on the same diameter 5 of this wheel according to Fig.2 «

Pie individual axle links 4 are made up of several parts composed and have a wooden step part 6 and a wood shaft 7 such that the step part or pedal 6 rotatable between the center wheel and the associated one outer wheel is arranged. The shaft 7 of each axle link 4 has tapered end pieces that fit into corresponding conical holes 9 of the wheels, between which the Shaft extends, inserted in a wedge shape and, for example, fastened by gluing. The shaft 7 also has a cylindrical central part on which the corresponding step part 6 is rotatably arranged. To this end are the individual pedal parts 6 with an axial longitudinal bore 8 of slightly larger diameter than the central cylinder

part of the shaft 7 provided so that the holes 8 the pedal parts 6 with some play rotatable on the shafts 7 are arranged.

The individual step parts 6 have a cross-sectional shape as shown in FIG. The step parts 6 consist of two more or less identical halves that are divided in the longitudinal direction of the step part and matched according to S ¹ Ig.4 so that they are firmly connected to one another by any connection means, for example by gluing and / or screwing »

In order to improve the appearance in particular, the free ends of the holes 9 and the shaft 7 through four metal caps 10 (which are only shown in Fig.l and 2) are covered, these caps have protruding sharp teeth or prongs that into the wheels 1 around the relevant ends of the holes 9 are driven around "

The Tre.tteile 6 of the axle links have parallel, flat surfaces _r which are each provided with two lung grooves of semicircular cross-section, as shown in Pig. 2 and 4. The aforementioned surfaces form a step on which the device in question is

user can put on their fites e, with the Person is now carried by these rescue parts and can balance and keep in equilibrium there.

• ζ

This balancing on the pedal parts 6 of the axle links and by exerting the crank action on this, the person concerned can now use the device to himself on the ground, on a path or any other To move the surface on which the device stands, the eccentrically arranged axle members 4 can be compared in their effect with cranks or pedals, through which then the wheels 1 to the port movement Device can be rotated «

The device described above is particularly simple in nature and can easily be mass-produced will. If desired, this can also be done according to the invention Center wheel omitted and replaced by a rigid connection between the two axle members 4, so that in this case the pedaling device consists only of two wheels 1 rolling on the ground, which are directly over a Kind of crankshaft connected to each other.

Although the main purpose of the device described is a
