Definitions

  • the invention relates to a device with a surface that can be moved in two spatial directions, in particular an omnidirectional treadmill.
  • Conventional treadmills have a surface on which one can move in one direction.
  • the treadmills are used for jogging in the fitness and home areas. They make it possible to cover any distance forwards or backwards without changing location.
  • VR virtual reality
  • the user moves virtually in the application or in the game.
  • the user wears VR glasses to simulate the game environment, with which the user is visually and auditorily shown the game environment and the course of the game.
  • H. can move or run virtually without changing its spatial position in any horizontal spatial direction (omnidirectional).
  • the present invention is not limited to VR applications and not to horizontal spatial directions alone. Taking into account the preferred area of application, however, the focus of the presentation is subsequently placed on enabling movement, in particular walking or running, without a significant change in the spatial position of the user in VR applications.
  • EP 0 948 377 B1 proposes a variety of solutions for omnidirectional treadmills.
  • the majority of the solutions require many small parts and give the runner running surfaces with inadequate properties.
  • the description (0081) - (0085) describes revolving belt units which are coupled to one another and form a good running surface and with which the movement of the running surface in the first Spatial direction is carried out.
  • endless belts are moved individually on the belt units in the area of the tread by means of special rollers by means of friction. Since the movement of the endless belts is only indirectly coupled via friction, there are differences in the movement of neighboring endless belts at higher loads.
  • the endless belts are not driven outside the area of the tread and are only coupled when they enter the area of the tread. Load impacts and additional wear occur during the coupling process.
  • US 6,123,647 A proposes a plurality of belt units that are moved by a large, transverse main belt.
  • the individual belt units form a surface next to each other.
  • To move the belts on the belt units it is proposed to drive each belt via rollers provided with two gear wheels.
  • the gears are driven by a toothed shaft.
  • the disadvantage is that the gear wheels of the belt units are in the deflection phase without contact with the tooth shaft and are brought into sudden engagement with the tooth shaft when a belt unit comes into contact with the tooth shaft again. Shocks occur in the transition phase, which lead to delays, noises and, subsequently, increased wear.
  • the individual belt units are not provided with a stable support frame with a sliding surface, which has an adverse effect since the belts alone only achieve an unstable surface.
  • US 7,780,573 B1 proposes individual belt units which are moved in the first spatial direction by means of chain wheels and chain and which are driven in the second spatial direction by friction via contact elements which are designed as omni-wheels.
  • the belt units are rotatably connected at one point to the small chain for transmitting the movement in the first spatial direction.
  • a second Connection to the chain has a possibility of displacement and therefore creates an asymmetrical position of the belt units in the curve.
  • the movement of the belts on the individual belt units is coupled via coupling elements such as constant velocity joints, corrugated tubes or universal joints. Sliding elements are provided to take into account the change in length during the coupling. Corrugated pipes without sliding elements have a short lifespan.
  • a disadvantage of this invention is that the belt units are connected only indirectly via the chain and not directly to one another, so that the coupling elements have to be brought into the required position at great expense.
  • additional displacement elements on both sides of a coupling element are required, and the displacement elements tend to jam, since the coupling elements are not intended to be held at the intersection of the axes of rotation of the rollers.
  • US 8,790,222 B2 also suggests individual belt units that are attached and moved on a main belt.
  • the belt units have a common, very long endless belt that is guided from one belt unit to the next by slanted guides on the underside. This means that all conveyor surfaces of the belt units have the same conveyor speed.
  • the endless belt is driven by bale-shaped rollers by friction.
  • a disadvantage of this design is the long endless belt, which leads to local stretching and thus warping of the endless belt when the speed changes rapidly due to inertial forces.
  • the object of the invention is to provide a device which does not have the aforementioned disadvantages of the known devices.
  • an omnidirectional treadmill which enables running in any direction of a plane.
  • the Fig. 1 shows a possible embodiment of a belt unit 1 with an endless main belt 2 rotating in the second spatial direction on roll 3 and roll 21 in a side view.
  • the rollers 3 and 21 are rotatably mounted on a support frame 4 of the belt unit 1.
  • the bracket 5 is pivotally connected at an axis 6 to the bracket 5, which is attached to the support frame of the adjacent belt unit 1.
  • the adjacent belt unit 1 is in turn pivotally connected to the next belt unit 1 via a link 5, and so on, so that all belt units 1 form a continuous endless chain.
  • a roller 7 is arranged, which runs on a fixed rail 8.
  • the rail 8 is at the ends with semicircular rails ( Fig. 2 ) so that a complete circulation of the belt units 1 in the first spatial direction can be carried out.
  • the Fig. 2 shows several rolls 3 of belt units 1 chained together in one part of the circulation.
  • the belt units are guided with rollers 7 on the fixed rail 8.
  • the rotational movement of a roller 3 about its axis is coupled to the rotational movement of the roller 3 of the adjacent belt unit 1 by means of a crown gear 15 described below.
  • the angle 27 between the axes of rotation of adjacent rollers 3 is changed over a wide range with the center axis 6.
  • a crown gear of the crown gear 15 is firmly connected to the associated roller 3 and forms a fixed rotating unit with the roller 3.
  • the coupling of the rotational movement of adjacent rollers 3 can take place in direct contact with crown gear drives, and the contact in the area of the axis 6 means that no further elements, such as sliding elements, are required for length compensation.
  • the axis 6 for changing the angle 27 of axes of rotation of adjacent rollers 3 is formed by a pivot connection.
  • the axis 6 is in the same position as the axis of rotation of the roller 7, which runs on the rail 8.
  • the Fig. 3 shows in a simplified overview the main functions of a device according to the invention.
  • the belt units 1 are arranged side by side so that the belt units 1 located in the upper, walkable part form a plane with the endless belts 2.
  • the belt units 1 roll with rollers 7 on fixed rails 8 ( Fig. 2 ), which causes a movement in the first spatial direction. Movement of the endless belts 2 of the belt units 1 results in a movement in the second spatial direction.
  • every direction of movement in the plane can be executed.
  • the movement in the first spatial direction is triggered by the drive wheel 11, with which a propellant 9 is moved, which in turn moves the belt units 1 in the first spatial direction.
  • the drive in the second spatial direction takes place in the embodiment shown via gear wheels 12, each of which is connected to a roller 3 of the belt unit 1.
  • the toothed wheels 12 can be driven by a toothed shaft 13 which is parallel to the first main axis.
  • the toothed shaft 13 can be driven via a drive wheel 14.
  • By rotating the gear wheels 12, the surface formed by the endless belts 2 is moved in the second spatial direction.
  • the Fig. 4 shows in the lateral representation direction several belt units 1, which are in circulation in the first spatial direction with the rollers 7 on the rail 8. At the end of the straight rail 8, the belt units 1 are guided in a curve and further combined to form an endless chain. From the illustration it can be seen that the distance between the rollers 7, due to the width of a belt unit 1, is large in relation to the radius of the semicircular rail at the end of the straight part of the rail 8. A strong polygon effect would occur in the curve when driving with a chain wheel. This is avoided by, in the preferred embodiment, the drive in the first spatial direction using an endless propellant 9.
  • the propellant 9 consists of a flexible band, preferably designed as a toothed belt.
  • the propellant 9 has its own oval circulation and is equipped with drivers 10 which come into contact with the belt units 1 in the straight part of the circulation and cause the movement of the belt units 1 in the first spatial direction.
  • Fig. 5 shows a detail of an embodiment of the teeth of a crown gear transmission of the present invention.
  • the above-mentioned conditions for the transmission are carried out with a crown gear transmission, the crown gears of which have a tooth shape formed from partial cones, the driven and the driven crown gear preferably being equipped with the same tooth shape.
  • a tooth 16, 17 can consist of a complete rotationally symmetrical truncated cone ( Fig. 5 ) or be composed of two partial cones ( Fig. 6 ).
  • the partial cones or the truncated cone have a cone axis parallel to the axis of rotation of the crown gear.
  • the conical surfaces are preferably produced by rotating a generatrix about the conical axis, so that cuts normal to the conical axis result in cross-sectional or circular cross-sections.
  • FIG. 5 an embodiment with a completely rotationally symmetrical truncated cone with straight cone generators is shown.
  • the cone 16 of the driving wheel touches the cone of the driven wheel at the contact point 20.
  • the crown wheels with axes of rotation 18 and 19 are pivoted at a pivot angle 27 via the axis 6.
  • the axis of rotation 24 of the cone generators lies parallel to the axis of rotation 18 of the driving crown gear.
  • the straight cone-generating end is inclined to the axis of rotation 24 at a taper angle 25.
  • the taper angle is between 8.5 ° and 13 °, preferably between 8.5 ° to 10.5 °.
  • the preferred taper angle range provides particularly favorable solutions with regard to the requirements (i) and (ii) mentioned, but it requires small tooth heights in order to avoid undercut.
  • the undercut can be avoided without reducing the tooth height by providing a chamfer 28 on the edge of the truncated cone.
  • the second cone end for the chamfer 28 is a straight line with a taper angle 29.
  • the cone with taper angle 25 is preferably connected to the cone with taper angle 29 with a rounding.
  • the resulting rotating body has preferably an arc as generatrix with taper angles that lie in the course of the arc between the taper angle of the two straight cone generators.
  • the length of at least one of the cone generators can go to zero, which only defines the end angle of the arc and the chamfer 28 appears as a simple rounding.
  • FIG. 6 An embodiment of crown gear teeth 16 and 17 composed of two partial cones is shown.
  • the crown gear tooth 16 consists of a partial cone 22 and a partial cone 23 arranged mirror-symmetrically thereto.
  • the mirror-symmetrical partial cone 23 takes over the drive contact after reversing the direction of rotation with the axis of rotation 18.
  • the axis of rotation 24 and the taper angle 25 are shown.
  • the axis of rotation 24 is parallel to the axis of rotation 18 of the driving crown gear.
  • the surface of the partial cone is generated by rotating a straight generatrix which is inclined by the taper angle 25 to the axis of rotation 24. Same taper angle ranges as for the full truncated cone below Fig. 5 described also apply to the partial cones in Fig. 6 .
  • Fig. 7 shows a preferred embodiment of the crown gear, in which a crown gear of the crown gear 15 is combined with a drive gear 12.
  • the endless belts 2 of the belt units 1 are located in the straight walk-in part of the device, they form a flat surface.
  • the part of the flat surface covered by the endless belts 2 has, by design, gaps which result from the arrangement of crown gear, drive and / or support structures.
  • An advantageous embodiment is therefore the combination of a crown gear within the drive gear 12.
  • belt units 1, which are located in the upper straight part of the revolution the axes of rotation of the rollers 3 are in an extended position.
  • the crown gear 15 is accommodated completely within the drive gear 12 in this position.
  • the design-related gap between the treadmills 2 is thus small and is only determined by the width of the drive gear 12.
  • the treadmill according to the invention provides the runner with a total area which can be moved in all directions. Narrow surfaces remain between the endless belts 2 of the belt units 1 and only take over the movements of the first spatial direction.
  • the invention relates to an omnidirectional treadmill which has a plurality of connected belt units (1) with a support frame (4) and endless belts (2) which are moved all around in the first spatial direction.
  • the endless belts (2) of the belt units (1) are moved in the second spatial direction.
  • the endless belts (2) are preferably driven in the second spatial direction via gearwheels (12) fixed on rollers (3) and a toothed shaft (13). All endless belts (2) are synchronized by coupling with crown gear drives (15) with a special tooth shape arranged between the belt units (1).
