Definitions
- the present invention concerns a method for controlling a device allowing a user to walk or run on the spot in an arbitrary direction, the device comprising a stationary central platform surrounded by a convex polygon shaped deck in level therewith, said deck being divided into trapezoid shaped roller conveyors, wherein each conveyor has rollers in parallel with the trapezoid bases, the shorter one of these adjoining said platform and the longer one of these forming a side of said polygonal shape, and wherein the rollers of said conveyors are driven in order to move a user stepping thereon back to said central platform. Further, the present invention concerns a device controlled by such a method.
- a device of the kind in question is previously known from the inter- national application WO 96/35481 A2.
- an embodiment of a device is revealed, comprising trapezoid roller conveyors having rollers divided into two equally long circular cylindrical parts with a central waist part inbetween. Further revealed therein is a method of controlling said device based upon data from accelerometers provided on the user of the device.
- the known device and method raise several concerns about safety.
- the waist part of the rollers increases risk of a user's clothing getting entangled in a hazardous way, even if said waist part, as indicated, is partly covered by means of a countersunk cover strip.
- the accelerometers used for the known method are hardly of any use when it comes to detecting the user stumbling, which for safety reasons would necessitate an immediate halt of the conveyors in order to avoid risk of squeezing for instance a finger.
- the mounting of the rollers is rendered quite complicated by the way chosen to drive the rollers, regardsless if a belt is used, encompassing the rollers and thus hampering their mounting or dismounting, or cog wheels are used, necessitating use of intermediate gears in order to get neighboring rollers rotate in the same and not opposite directions.
- WO 2010/089618 A2 Another prior art device is revealed in WO 2010/089618 A2.
- This device also comprises a platform made of trapezoidally shaped roller conveyors, but the rollers of these are of a safer design. They are continuous circular cylindrical and are driven by friction wheels from below, which minimises the risk of a user's clothing getting entangled.
- a circular railing is used, that encompasses the user at some distance.
- the railing can carry sensor means measuring the distance of the user from the railing, wherein the distance data is used as an input for controlling the roller conveyors.
- the latter device is far easier to assemble than the former one, but the great number of friction wheels used therein leaves some room for improvement. Further, the use of distance measuring sensor means arranged on a circumferential railing does not render it possible to control the device safely for instance when a user kneels or stumbles and falls.
- a first object of the invention is to devise a method of controlling a device according to the preamble in an advantageous way.
- a second object of the invention is to provide a device with improved trapezoid shaped roller conveyors.
- the first object is achieved by means of a method according to the preamble further characterized by the following steps: mounting a plurality of video cameras above the device on a height well above a user thereof, said cameras being arranged in a defined matrix and directed downwardly; providing a direction indicating marker on top of said user; monitoring the position and size of said marker by means of said cameras; controlling the speed of the roller conveyors depending on said markers distance from said central platform as seen from above by said cameras at an elevated speed when said distance is large and at a lower speed when said distance is small; and halting the roller conveyors when said distance is nil.
- video cameras instead of accelerometers, like in the prior art device, the user only has to wear a simple marker, e.g.
- the method according to the invention preferably comprises the further step of halting the roller conveyors when the size of said marker as seen from above by said cameras is substantially decreased or when the marker can no longer be seen at all by said cameras.
- This step marks another important safety feature, because it ensures that the roller conveyors of the device according to the invention come to an immediate halt should the user kneel or lie down or trip and fall or just lose the marker.
- the method according to the invention preferably comprises the further steps of mounting video displays or screens, that can be viewed by the user, and of adapting the content shown on said video displays or screens to the speed of the roller conveyors, the actual position and size of said marker and to its direction.
- This makes it possible to greatly enhance the users overall perception in a virtual reality environment created by means of said video displays or screens.
- the theme to be shown on said video displays or screens can be chosen depending on the type of marker used. This makes the device according to the invention more user friendly and adaptable, for instance by simply changing from one cap, having one type of marker thereon, to another cap, having another typ of marker thereon.
- the method according to the invention preferably comprises the further step of lowering the speed of the roller conveyors if the direction of the marker on top of the user indicates that the user, having stepped on the deck is facing in a non-radial direction in relation to the central platform.
- This step takes into consideration that a user, who for example turns his head while walking, usually slows his walking speed and therefor could become unbalanced if moved to fast by the roller conveyors of the device according to the invention.
- the second object is achieved by means of a device for allowing a user to walk or run on the spot in an arbitrary direction, the device comprising a stationary central platform surrounded by a convex polygon shaped deck in level therewith, said deck being divided into trapezoid shaped roller conveyors, wherein each conveyor has rollers in parallel with the trapezoid bases, the shorter one of these adjoining said platform and the longer one of these forming a side of said polygonal shape, and wherein the rollers of said conveyors are driven in order to move a user stepping thereon back to said central platform, wherein said rollers are continuous circular cylindrical, and wherein beneath each conveyor there is a driving means for frictional driving engagement with said rollers from below, said device being characterized in that said driving means comprises an endless belt extenting along the roller conveyor in frictional driving engagement with all rollers thereof, and in that said driving means frictionally engages the conveyor rollers in a central part of these, said rollers being journalled at end parts thereof in resiliently mounted bearings.
- a device according to the invention is much easier to accomplish than a drive solution comprising individual rubber wheels, and the built in resiliency of the device according to the invention makes the roller conveyor more pleasant to walk or run upon, just like a slightly resilient sporting floor, and assures good driving contact between the rolls of a conveyor and said driving means even if a user steps on rolls far from the central parts of these.
- the driving shafts of said driving means are interconnected by flexible joints and driven by a single motor. It is well known to use ssen joints, also known as universal joints, to transmit a rotational movment around a corner, if the angle of that corner is within reasonable limits.
- one such joint may be used at every transition between two adjoining roller conveyors in order to transmit power from a single motor to all of the conveyors in minor angular steps that do not cause any blocking problems.
- the deck of the device according to the invention is prefereably circumferentially enclosed by a stationary floor plate in level therewith.
- the floor plate marks the outer limits of the device and can be used as a safety retreat, for example if the speed of the roller conveyors of the device is to slow to carry the user back to the central platform.
- said floor plate covers parts of said driving means. This is very advantageous, because it simplyfies access to the driving means.
- said deck is of regular convex polygon shape and its roller conveyors are of uniform isosceles trapezoid shape.
- Fig. 1 shows the preferred embodiment of the device according to the invention in a perspective view
- Fig. 2 shows the device according to Fig. 1 from above;
- Fig. 3 shows portion A of Fig. 2 in greater detail with some parts broken away;
- Fig. 4 shows the device in a side view along section B-B in Fig. 2;

- the device 1 is generally circular when seen from above.
- the circle periphery is created by a horisontal ringshaped floor plate 2, which by radial lines is divided into several sectors 3.
- a horisontal ringshaped floor plate 2 which by radial lines is divided into several sectors 3.
- the framing structure 4 with its radial beams 5 is best seen in Fig. 3, where two floor sectors 3 are removed to reveal the substructure of the device 1 .
- each floor sector 3 forms a line, that runs straight from one of the division lines to the next. This makes the sixteen floor sectors 3 create a regular hexadecagon shaped ring opening.
- a horisontal deck 6 is provided in level with the floor plate 2.
- the deck 6 too is ring shaped and concentric with the floor plate 2.
- the deck 6 consists of a total of sixteen identical roller conveyors 7, each one of an isosceles trapezoid shape with rollers 8 in parallel with the trapezoid bases.
- the sixteen roller conveyors 7 are radially aligned each with one of the sixteen floor sectors 3 and connect to these without any major interruption each with a roller 8 along the longer baseline of the roller conveyor 7 in question.
- the opposite rollers 8 along the shorter baselines of the roller conveyors 7 define a regular hexadecagon shaped opening, which forms the inner circumference of the deck 6.
- horisontal central platform 9 is provided in level with both the floor plate 2 and the deck 6.
- the platform 9 is stationary and has the shape of a regular hexadecagon and a size that fits the inner circumference of the deck 6 without leaving any major interruption.
- the central platform 9 is resting on said framing structure 4, which has its radial beams 5 running all the way into the center of the circular device 1 .
- the deck 6 is also resting on the framing structure 4, however not directly on the radial beams 5 but, as can be seen in the detailed view in Fig. 5, on resilient elastomer strips 10 mounted on top of these.
- side boards 1 1 of the roller conveyors 7 rest.
- the side boards 1 1 are kept in place by means of studs 12 which are attached to the radial beams 5 and freely pass orrifices in said side boards 1 1 , thus enabling some suspended side board movement within limits given by heads of the studs 12 protruding on top of said orrifices.
- rollers 8 of the roller conveyors 7 are journalled in bearings 13 held by said side boards 1 1 and mounted as close as possible to each other without touching each other both in parallel within one and the same roller conveyor 7 as well as sideways between two roller conveyors 7 adjoining on top of a radial beam 5 of said frame structure 4.
- the rollers 8 would be freely rotable if there was not a driving means 14 arranged underneath them in frictional contact with each of them.
- the driving means 14 for every roller conveyor 7 comprises an endless belt 15.
- the belt 15 extends radially towards the center of the device 1 , centrally in relation to the roller conveyor 7 in question.
- a sliding support 16 under the upper course of each endless belt 15 these courses are pushed into frictional engagement with all rollers 8 of the roller conveyors 7, wherein the resilient suspension of the roller conveyors 7 ensures perfect belt-roller contact even in situations where the rollers 8 are loaded eccentrically.
- Each one of the endless belts 15 runs about end pulleys 16, 17, of which preferably the inner one 16 is a idling pulley and the outer one 17 is a driving pulley. Further, the driving pulleys 17 are driven by means of a cardan shaft arrangement 18, that comprises flexible joints 19 on both sides of the driving pulleys 17 and runs from a single electric motor 20 to a first driving pulley 17 and from there to the next driving pulley 17, and so on.
- the cardan shaft arrangement 18 is well hidden below the floor plate 2 and yet easily accessible by simple
- roller conveyors 7 which are fairly easy to remove thanks to the fact that they are frictionally driven and thus can be lifted off easily once the securing studs 12 are removed.
- Fig. 6 the device 1 according to the preferred embodiment described above is shown together with some extra features provided in order to render a method of controlling the device 1 possible.
- the previous reference numbers are mostly omitted, because the perspective view of the device 1 as such is identical with the one in Fig. 1 .
- the arrangement in Fig. 6 comprises a cage 21 , that surrounds the device 1 .
- the cage 21 has erect post 22 and a roof comprising diagonally extending rails 23.
- the posts 22 are preferably used to mount video displays or screens (not shown) that enable creation of a per se known virtual reality environment.
- the rails 23 carry video cameras 24, which are directed downwardly. As can be seen the video cameras 24 are arranged in a well defined matrix at a height well above a user 25 of the device 1 .
- the user wears a cap on top of which there is a marker 26 of a defined pattern that is direction indicating.
- the video cameras 24 track the position of the marker 26, the size thereof and its direction and use that information in order to decide where the user 25 of the device 1 presently is and where he is heading or facing. If the user is not in the center of the device 1 on the stationary platform 9 or leaves the platform 9, the electric motor 20 is activated in order to drive the roller conveyors 7 and make them return the user 25 stepping thereon to the platform 9. According to the method the speed with which the user 25 is returned to the stationary platform 9 is higher the further away the user 25 is from the platform, which means too that speed is lowered once the user 25 comes close to or is close to the stationary platform 9. Once the user 25 is back on the stationary platform 9, the electric motor 20 is again stopped and thus the roller conveyors 7 halted.
- the marker 26 on top of the user 25 becomes obscured or no longer is detectable, which can be due to the user 25 stumbling and falling or stepping past the deck 6 and onto the floor plate 4, or due to the marker 26 coming off for some reason.
- a detected change of perceived size of the marker 26, which can be due to the user 25 kneeling or lying down, can be used as an indicator to
- the speed of the roller conveyors 7 is based on the position of the user 25 relative to the central platform 9 with thereto optionally derivating elements to account for the time over which user positional changes occur and adapt the speed of the roller conveyors 7 accordingly, and integrating elements to allow faster maximum conveyor speeds over time.
- the method according to the invention can comprise the further steps of mounting video displays or screens (not shown), that can be viewed by the user 25, and of adapting the content, that is the viewing angle or the moving speed, of the content shown on said video displays or screens to the speed of the roller conveyors 7, the actual position and size of said marker 26 and to its direction. Further, it is well possible to chose the theme to be shown on said video displays or screens in dependence on the type of marker 26 used, such as a marker 26 on military helmet for initiating a combat scene or a marker 26 on a station-master cap for initiating a train platform scene.
- the method according to the invention can further comprise the step of lowering the speed of the roller conveyors 7 if the direction of the marker 26 on top of the user 25 indicates that the user 25, having stepped on the deck 6 is facing in a non-radial direction in relation to the central platform 9. This takes into consideration the fact that a user 25, who turns his head while walking, usually slows his walking speed and therefor could become unbalanced if moved to fast by the roller conveyors 7 of the device 1 according to the invention.
