Abstract:
1. A moveable device, comprising a planar element with at least one wheel supported rotational about a first rotary axis, a handle support carrying a handle at the distal end of the planar element, and an end proximal from the planar element, a folding link located adjacent to the first wheel, which connects the proximal end of the handle support to the planar element pivotally about a first pivotal axis such that in an operating state the handle support is aligned at an angle in reference to the planar element, perpendicular or almost perpendicular, and thus the distal end of the handle support shows a maximum distance from the planar element and in an idle state the distal end of the handle support shows a minimum distance from the planar element, and at least one second wheel supported rotational about a second rotary axis, which is arranged at the distant end of the planar element distanced from the arrangement comprising the first wheel and the folding link, characterized in that the second wheel is arranged at the planar element additionally pivotal about a second pivotal axis extending approximately in the direction of motion and coupled to the handle support via a mechanism, which converts a pivotal motion of the handle support in reference to the planar element about the first pivotal axis into a pivotal motion of the second wheel about the second pivotal axis such that the second rotary axis of the second wheel in the idle state shows a greater angle in reference to the planar element than in the operating state.
