Abstract: An implement to be used as a plaything by children and as training equipment by grownups, includes a hoop of a diameter larger than the height of a person standing on its inside surface and treading forwards with the aim to roll the hoop along a floor surface. A chassis frame is slidingly attached to the two lateral edges of the hoop. The chassis frame supports a front wheel and a steering handle extending towards the hands of the person in the hoop. Treading on the hoop's inside surface propels the hoop along the floor while the front wheel is steered by the user. A hoop sized for adults can be used as a training implement by mounting it in rotatable alignment on a stationary base. The training implement may be configured for use in various positions, either upright, or when sitting and even while laying down.

Abstract: A toy in the shape of a collapsible and expandable box is made of cardboard and has a stiff, square top and bottom and four side walls which can be folded to the outside along central folding lines by pressure onto the top. Each side wall is provided with an inwardly extending tongue, and each two tongues on opposite side walls are connected by elastic bands or springs which pull the walls back from their folded position into planar state, as soon as the pressure on the top is released. In this position the toy forms a cube, which may be decorated with pictures, maps, symbols or the like.
