Abstract
Disclosed is an omnidirectional treadmill which has several connected belt units with supporting frames and endless belts which are moved revolving in the first spatial direction. In the second spatial direction, the endless belts of the belt units are moved. The endless belts are driven in the second spatial direction preferably by gear wheels mounted on rolls and by a toothed shaft. The movement of all endless belts is synchronized by coupling with special tooth form crown gears arranged between the belt units.
Claims20
A device with a surface movable in two spatial directions, the device comprising:
- a plurality of belt systems movable in a first one of the spatial directions, each of the belt systems being provided with a supporting frame, each of the supporting frames of a respective one of the belt systems being pivotally-connected with the supporting frame of an adjacent one of the belt systems via one or more axis forming a rotary connection at a fixed distance, each of the belt systems being configured to be driven by at least one drive system, the belt systems being provided for movement in the second spatial direction with a plurality of driving rolls and driven rolls and a plurality of endless belts which are coupled to a drive, rotary movement of one of the driving rolls with an adjacent one of the driven rolls of an adjacent one of the belt systems being coupled by a crown gear with a tooth profile with which variable rotary movements of the driving roll are continuously transmitted to the driven roll when an angle between the axis of rotation of the driving and driven rolls changes, an axis lying in an area of an engagement profile and outside a point of intersection of the axes of rotation of the driving and driven rolls.
