Definitions
- This invention relates to ski simulators in the form of inclined treadmills
- Such simulators may be used either for teaching skiing technique, or they may be used as an exercise apparatus, either for general fitness, or more specifically for training the muscle groups used m the sport of skimg
- US 5,162,029 discloses a ski simulator comprising an inclined deck having a moving belt of material with a low coefficient of friction
- a hand rail is provided towards the front of the simulator which the skier holds to maintain a position on the ski deck
- a support rail is also provided behind the skier which supports a belt for attachment to the skier
- the angle of inclination of the ski surface may be adjustable and that the speed of the treadmill may be adjusted accordingly
- a known apparatus having adjustable speed and angle inclination requires a supervisor to be present during use of the apparatus in order to continuously vary the speed of the treadmill according to the way the user of the apparatus is skiing
- an apparatus for simulating a ski slope comprising a ski deck having a surface defined by a continuous belt of mate ⁇ al formed in a closed loop around rollers at the front and back of the ski deck, the belt of mate ⁇ al being d ⁇ ven so that the surface of the ski deck ⁇ des up the slope, the angle of inclination of the deck with respect to a base of the apparatus and the drive speed of the material being controllable.
- the apparatus further composes a handrail towards the front of the deck, and w herein the angles of inclination of the handrail with respect to the base and w ith respect to the surface vary as the angle of inclination of the deck is ⁇ a ⁇ ed
- This arrangement of the handrail can be configured such that the natural position of the skier on the ski deck when holding the handrail remains substantially fixed as the angle of inclination of the ski deck is vaned In this , the area of the ski deck can be minimised because the user remains substantially static with respect to the ski deck
- a support rail is provided towards the back of the deck, and the angles of inclination of the support rail with respect to the base and with respect to the surface also vary as the angle of inclination of the deck is vaned
- the support rail is preferably provided with a cut-off switch coupled to the user of the apparatus, such that if the user falls the cut-off switch is actuated
- the movement of the support rail is therefore designed to keep the user at a fixed distance from the support rail, so that the cut-off switch remains functional at all angles of inclination
- the angles of inclination of the handrail and of the support rail with respect to the base change by an amount less than the change m the angle of inclination of the deck It has been found that the inclination of the handrail and the support rail should not remain fixed with respect to the base, but neither should they remain fixed with respect to the ski deck, when the angle of inclination of the ski deck changes It has been found that, for optimum comfort and positioning of the skier, the handrail and support rail should tilt, but to a lesser extent than the angular movement of the ski deck
- the angle of inclination of the handrail with respect to the base may need to change by a different amount to the angle of inclination of the support rail w ith respect to the base, as the ski deck moves
- the support rail and the hand rail may each ha ⁇ e an extendable base, and the base of the hand rail and of the support rail may then be positionally fixed with respect to the base, and a support part of the hand rail and of the support rail may then be positionally fixed with respect to the deck
- the base and the deck thus constitute a linkage mechanism which governs the angular movement of the support rail and the hand rail as the angle of inclination of the deck is vaned
- the extendable base of the hand rail and of the support rail may compnse at least one hydraulic cylinder, with the hydraulic cylinder at the base of the support rail being actuated to vary the angle of inclination of the deck
- an electnc motor or other arrangement may provide the extension of the base of one of the support rail or the hand rail, which vanes the inclination of the deck
- the axis about which the deck is able to pivot is preferably selected such that the angle of inclination of the handrail with respect to the base changes by a different amount to the angle of inclination of the support rail with respect to the base when the angle of inclination of the ski deck is vaned
- the height of the hand rail above the deck may also be varied as a function of the angle of inclination, so that the hand rail is at a height corresponding to the correct position of the hands for holding ski poles.
- the use of feedback enables the speed to be controlled so that the skier can remain at a substantially fixed position, which may avoid the need for a hand rail
- the feedback system may compnse a position sensor for detecting movement of the user up or down the slope, wherein if movement is detected towards the front of the deck the dnve speed is increased and if movement is detected towards the back of the slope the dnv e speed is reduced
- the apparatus may further compnse a hand rail towards the front of the deck and wherein the feedback system compnses a sensor for detecting the force applied by the user to the handrail, wherein if a force is detected on the handrail towards the front of the deck the dnve speed is increased and if a force is detected on the handrail towards the back of the slope the dnve speed is reduced
- the use of force feedback from the handrail provides a simple feedback system Once an appropriate speed has been reached corresponding to the manner in which the user is skiing, the user may let go of the hand rail and maintain a constant skiing rhythm If the skier then wishes to ski in a different manner, for example with sharper turns, he can then hold on to the handrail, and the sharper turns will cause him to pull back on the handrail Consequently, the speed will increase and the skier can then maintain a rhythm with sharper turns at a higher speed, and can again let go of the hand rail
- the apparatus will self-calib
- the handrail may be piv oted at its base, and the force sensor then detects the pivoting force of the handrail, forwards or backwards
- the dnve speed is preferably varied by up to predetermined maximum amounts above and below a default dnve speed associated with the angle of inclination This default speed may be selected as a function of the weight of the user
- the card reader may also be for reading information concerning the weight of the user, the apparatus determining the belt speed for different angles of inclination from the weight information
- the card may be a magnetic swipe card or a sw ipe card
- an apparatus for simulating a ski slope comp ⁇ sing a ski deck having a surface defined by a continuous belt of matenal formed in a closed loop around rollers at the front and back of the ski deck, the belt of matenal being dnven so that the surface of the ski deck rides up the slope, the angle of inclination of the deck with respect to a base of the apparatus and the dnve speed of the mate ⁇ al being controllable, the apparatus having a plurality of settings co ⁇ esponding to different simulated ski conditions, each setting defining an associated drive speed and angle of inclination
- the provision of a number of settings enables a user of the apparatus to select a setting corresponding to their skiing ability or the effort to be exerted dunng fitness training, and to use the apparatus without supervision
- the relationship between the dnve speed and the angle of inclination for each setting can be vaned as a function of the weight of the user In this way, the default setting will be approximately sufficient for the dnve speed to support the user without the user needing to apply a large force to the handrail
- This hydraulic cylinder arrangement enables the nsmg and falling of the ski deck to occur at the same speed, even with a single constant pressure source for the hydraulic cylinder
- Accurate control of the speed at w hich the ski deck ⁇ ses and falls enables the speed of the belt to be vaned appropnately dunng the raising and lowenng of the ski deck
- the dnve speed is preferably controlled automatically to v arv m a predetermined manner as the angle of inclination is vaned
- an apparatus for simulating a ski slope comprising a ski deck having a surface defined by a continuous belt of material formed in a closed loop around rollers at the front and back of the ski deck, the belt of material being driven so that the surface of the ski deck ndes up the slope, the angle of inclination of the deck with respect to a base of the apparatus and the dnve speed of the mate ⁇ al being controllable, wherein the belt comp ⁇ ses a backing layer, a rubber ply layer bonded to the backing layer, and a polypropylene matting bonded to the rubber ply layer, the matting having bundles of strands projecting through openings in a support layer of the matting, the strands having a length between 15 and 30mm and the spacing between adjacent bundles of strands being less than 5 mm
- the apparatus may be provided w ith a screen at the front of the deck for displaying images selected according to the setting of the angle of inclination of the deck
- a screen at the front of the deck for displaying images selected according to the setting of the angle of inclination of the deck
- aspects of this invention may enable the deck to have an area of less than 5 square meters
- the deck may have dimensions of approximately 2 meters x 2 meters, or even 1 5 meters x 1 5 meters These dimensions make it practical for the apparatus to be placed alongside conventional gymnasium equipment
- Figure 1 shows an apparatus for simulating a ski slope according to the inv ention
- Figure 2 shows a force sensor arrangement used in the apparatus of Figure 1
- Figure 3 is a diagram illustrating how the position of the skier changes as the angle of inclination of the deck vanes
- Figure 4 shows in greater detail the a ⁇ angement used in the apparatus of Figure 1
- Figure 5 shows a hydraulic piston arrangement used in the apparatus of Figure 1
- Figure 6 shows an electnc actuator used in the apparatus of Figure 1
- Figure 7 shows a modification to the apparatus of Figure 1 incorporating a screen
- FIG. 1 shows an apparatus 10 for simulating a ski slope
- the apparatus 10 compnses a ski deck 12 having a surface defined by a continuous belt of material 14 formed in a closed loop around rollers at the front and back of the ski deck 12
- the belt 14 is dnv en around the rollers, for example by an electnc motor, so that the upper surface of the belt 14 travels in the direction represented by arrow 16, which is up the slope when it is inclined
- the apparatus 10 has a fixed base 18 and an upper frame 20
- the front and back rollers are supported by the upper frame 20, and the upper frame 20 and the belt 14 can pivot about an axis which may coincide with the axis of rotation of the front roller This enables the back of the deck 12 to be raised, as represented bv arrow 22 In this way, the angle of inclination of the deck 12 with respect to the base 18 is controllable
- the dnve speed of the belt of mate ⁇ al 14 is also controllable, so that the d ⁇ v e speed is
- the apparatus further comp ⁇ ses a handrail 24 towards the front of the deck 12 and a support rail 26 towards the back of the deck 12
- a cut-off switch 28 is mounted on the support rail 26, and is coupled to a belt 30 to be worn by the user of the apparatus
- the belt 30 and the cut-off switch 28 are arranged such that the deck 12 is stopped if the user falls over
- the speed of the belt of mate ⁇ al 14 is selected such that the forces on the skier up and down the slope are approximately equal, so that the user is in equilibrium
- This equihb ⁇ um will depend not only on the speed of the belt and the angle of inclination of the belt, but also on the weight of the user, the surface of the skis used and the skiing style adopted by the user
- the handrail 24 is held dunng use of the apparatus
- the apparatus is provided with a control panel 31 which provides a number of settings corresponding to different ski runs Each setting defines an associated dnve speed and angle of inclination which can be reached automatically by the apparatus
- the skier can thus select a setting corresponding to their skiing ability or the effort to be exerted dunng fitness training, and to use the apparatus w ithout supervision
- the relationship between the dnve speed and the angle of inclination for each setting can be v a ⁇ ed as a function of the weight of the user, and the control panel 31 thus has a weight input function for this purpose
- the default setting w ill be approximately sufficient for the drive speed to support the user without the need to lean heavily or pull back heav lly on the hand rail
- a prefe ⁇ ed belt mate ⁇ al has been found to be polypropylene matting, which has similar surface properties to fresh snow
- a problem w ith the use of such mate ⁇ al for artificial ski slopes has been that the performance degrades when the surface becomes dirty
- the use of this matenal in the apparatus of the invention is particularly suitable because the rotation of the belt around the rollers provides a self-cleaning operation
- the belt compnses a conventional frictional belt as a backing layer, a 3mm rubber ply layer bonded to the belt, and the close pile matting bonded to the rubber ply layer
- the matting has strand lengths of between 15 and 25mm, preferably around 20mm
- the spacing between adjacent bundles of strands projecting through individual holes m the backing of the matting is less than 6mm, and preferably around 5mm
- Figure 2 shows a force sensor arrangement 40 associated with the handrail 24 for detecting the force applied to the handrail 24 by the user
- the handrail 24 is pivoted at its base at pivot point 42 which enables the hand rail to tilt with respect to the base 18
- the hand rail is positionally fixed with respect to the upper frame 20 at a pivot connection 43
- Some slack is provided in this coupling to enable force detection, explained below
- a spring arrangement 44 biases the handrail 24 into a central default position with respect to the upper frame 20
- the handrail 24 is moved aw ay from the central position, and this is detected by the force feedback system 40 Detection of movement of the handrail 24 may either be by a contact arrangement or by pressure sensors
- the pivoting of the handrail 24 either forward or backward is limited by the oval opening 47 which houses the pivot 43 and in the limit position a contact closes to indicate that a force greater than a preset minimum is being applied to the handrail 24 either in a forward or a backward direction.
- the pivot connection between the upper and lower frames is not shown in Figure 2, but as described above this may coincide with the axis of the front roller.
- the force feedback signal is used to control the drive speed of the belt of material 14, so that when a force is detected on the handrail towards the front of the slope, the drive speed is increased, and when a force is detected on the handrail towards the back of the deck, the drive speed is reduced.
- the speed of the belt of material 14 is controlled automatically to match the skiing style, the weight, and the skis of the user to maintain the user in equilibrium. For example, if the user decides to practice sharper turns, this provides increased resistance which slows the user down. The effect of this is that the user will be dragged up the slope by the belt of material 14, and he will thereby pull back on the handrail 24. The speed of the belt of material 14 will accordingly be reduced, and a new equilibrium will be found.
- Figure 3 illustrates the positioning of the skier on the ski deck 12 at different angles of inclination of the deck.
- the position of the handle of the handrail 24 is selected such that when a skier holding the handrail 24 has the correct stance, the skis are positioned approximately in the middle of the ski deck 12.
- the angle of inclination is increased, as shown in Figure 3B, the skier's stance changes and in particular the skier's body remains substantially upright whereas the skier's knees are more flexed.
- Figure 3B illustrates the position of the skier over the deck 12 when the handrail 24 and the support rail 26 remains at the same inclination with respect to the base This could be achieved using a parallelogram coupling arrangement
- the applicant has recognised that if the angle of inclination of the handrail with respect to the base remains constant then the skier moves towards the back of the ski deck, as shown, and becomes closer to the support rail 26
- Figure 3C illustrates the position of the skier over the deck 12 when the handrail 24 and the support rail 26 is pivoted together with the deck 12, in other words the angles of inclination of the handrail with respect to the ski surface remains constant
- the applicant has recognised that, as can be seen m Figure 3C, the result is that the skier moves towards the front of the ski deck
- a preferred implementation of the invention shown in Figure 3D thereby ensures that the angles of inclination of the handrail with respect to the base and with respect to the surface vary as the angle of inclination of the deck is vaned Furthermore, the angles of inclination of the support rail with respect to the base and with respect to the surface also vary as the angle of inclination of the deck is vaned
- the movement of the hand rail ensures a constant position of the user over the ski deck, and the movement of the support rail 26 is intended to provide a constant distance betw een the belt 30 and the cut-off switch 28 provided on the support rail 26, so that the cut-off sw itch remains operative
- the constant user position enables the area of the deck to be reduced
- short skis are also used, to reduce the required area of the deck 12
- Figure 4 shows in greater detail the system of linkages which provides the angular relationship between the handrail 24 and the support rail 26 shown in Figure 3D
- the base 42 of the hand rail 24 is positionally fixed with respect to the base 18, and a pivot point 43 of the hand rail is positionally fixed with respect to the deck 20
- the distance between these two points 42 and 43 is variable, as a hydraulic cylinder arrangement is provided
- the base 50 of the support rail 26 is positionally fixed with respect to the base 18, and a support part 51 of the hand rail is positionally fixed with respect to the deck 20
- the distance between these two points 50 and 41 is also va ⁇ able, as a hydraulic cylinder arrangement 52 is provided
- Figure 4 One preferred system of angles is represented in Figure 4 As shown, the hand rail angle with respect to the deck 12 changes more slowly than the support rail angle with respect to the deck 12 For an incline of 30 degrees, the example illustrated in Figure 4 gives nse to an angular movement with respect to the deck of 13 7 degrees for the support rail and 12 4 degrees for the hand rail.
- the angle of the hand rail and of the support rail with respect to the base may change by between 1/3 and 2/3 of the change in the angle of inclination of the deck 20
- the angle of the hand rail and of the support rail with respect to the deck then changes by between 2/3 and 1/3 of the change in the angle of inclination of the deck 20
- a further possibility is to alter the height of the hand rail above the deck, as a function of the angle of inclination
- “height” is meant the length of the up ⁇ ght arm of the hand rail from the deck
- the distance between points 42 and 43 may again va ⁇ able passively, as a function of the angle of inclination
- the length of the hand rail above the point 43 may also be controllable by an independent dnve mechanism
- the hand rail may have an outer sleeve which is shdable over an inner core, and this sliding is then controlled by the drive mechanism
- the slope increases, the hand rail rises, so that it remains in a position corresponding to the co ⁇ ect position in which the ski poles are to be held This is shown in dotted lines in Figure 3D
- Figure 5 shows the operation of the hydraulic cy Under a ⁇ angement 52 used to raise and low er the ski deck 20
- the cylinder arrangement has a first cyhnd ⁇ cal chamber 54 on one side of a piston 56 and a second annular chamber 58 on the opposite side of the piston 56
- the area of a section through the first chamber 54 is approximately double the area of a section through the second chamber 58
- the base of the piston rod 60 is fixed to the base 18 of the apparatus, and the sleeve 62 defines the contact point 51 where the support rail 26 is fixed to the upper frame 20
- a pressure from a pressure source 64 is applied to both chambers by means of a valve arrangement 66 This results in a net force d ⁇ ving the support rail upwards
- the pressure from the pressure source 64 is applied only to the second chamber 58, which results in a force d ⁇ ving the support rail downwards
- the force up and down is equal, so that the deck can be controlled with a single, constant value, pressure source, to give equal raising and lowenng speeds Dunng lowering of the ski deck, the effect of gravity acting to increase the speed of decline of the deck is counteracted by the fluid resistance of an outlet valve from the first chamber It is desirable to know the speed at which the deck 20 rises and falls so that the speed of the belt 14 can be controlled in appropnate manner when the incline of the deck is being changed
- the support rail is d ⁇ ven by the hydraulic cylinder a ⁇ angement of Figure 5
- FIG. 6 shows schematically one possibility in which the rear part of the deck is caused to raise and lower using a scissor arrangement, in w hich an electnc ball screw actuator 72 is used to control the extension or compression of the scissor a ⁇ angement, and thereby the height of the back of the deck This provides a rapidly controllable movement
- the pivot connections of the rails provide the desired angular mov ement of the rails as the deck is raised and lowered
- Figure 7 shows a modification to the apparatus of Figure 1 incorporating a screen
- the images are selected according to the setting of the angle of inclination of the deck, to improve the simulation
- the screen may be used to show images and runs of a resort where a skier will be going while he or she is exercising in preparation for the holiday The skier can thus get a feeling for the resort in advance
- the screen may be used to sell advertising space to ski resort organisations or ski equipment suppliers
- the screen may also include a camera so that the user can see images of himself or herself, and/or a mirror
- the front of the deck may also be provided w ith a fan 80 or a series of fans 80, and the number of fans actuated, or else the speed of the fan or fans, is controlled as a function of the angle of inclination, to represent the skier's speed through the air
- the ski deck is preferably mounted over the front and rear roller without being constrained laterally
- the forces on the deck may result in lateral movement of the belt
- Figure 7 shows a tracking control system to ensure correct alignment of the belt
- a first sensor 82 is provided on each side of the belt If the belt moves laterally enough to cover the sensor, reflection from the underside of the belt can be detected, and the axis 84 of the front roller can be shifted appropriately for a fixed time penod, to force the belt back to a central lateral position
- a second senes of sensors 86 will detect further misalignment, indicating incorrect operation of the automatic tracking control system, and act as a safety cut-out
- the sensors 82,86 may be detect reflection (for example comp ⁇ sing a light source such as a phototransistor and a light detector such as a photodiode) or Var ely a light source may be mounted above or below the belt with a light detector mounted on the opposite side of the belt, so that a light path is interrupted by the belt
- the outer pe ⁇ meter of the deck may also be provided with hne-of-sight sensors, so that any object projecting off the deck (such as a wrongly positioned ski) can cause a safety cut-out
- These sensors may be provided all around the deck, or at least at the back of the deck
- a further aspect of the invention provides users with an identity card which can be read by the simulator, which then allows the user to operate the machine to speeds or angles of inclination which match the user's level of expe ⁇ ence
- This identity card comp ⁇ ses a smart card, and a user may then be required to undergo basic training before obtaining a smart card, or before the smart card enables the user to operate the simulator without supervision
- Figure 7 shows schematically a smart card reader 90 as part of the control panel 31
- a user may be required to have three safety training lessons before the smart card will allow them to use the simulator independently This enables a gym hav mg the simulator to ensure the safety of users of the simulator
- the user's smart card has been updated to indicate that the three lessons have been completed, the user may be able to ski on low gradient (green) slopes independently
- An additional lesson will then allow the user access to the next gradient of slope
- the user may choose to see a pre-recorded video taken by a skier skiing tne selected run, or else footage or information concerning a chosen resort Dunng a lesson, the footage of the run being skied may include a skier to be followed The skier being followed will then be skiing at a level corresponding to the level of the lesson, so that the user will be instructed to copy the skier in front This keeps the user looking forward and m an up ⁇ ght stance
- a user autho ⁇ sed to use the simulator independently may also choose to follow a skier
- the smart card may also be used to enable a user to follow a training schedule, w ith the simulator providing a tailor- made training routine for the user, in preparation for a ski holiday, for example
- the smart card also contains information concerning the weight of the user, so that the ratio of angle of inclination to belt speed can be determined It can also contain information concerning the height of the user, so that the extension of the hand rail can be tailored to the user, so that the users hands will always be positioned in the correct position for holding the ski poles
- a force feedback system associated with the hand rail has been descnbed in detail
- a sensor may be provided for detecting the position of the user's boots, which should remain at a substantially constant height up the slope The front or back of the user's skis will naturally rise and fall up and down the slope dunng turns, whereas the user's feet will not
- a light probe and sensor arrangement may be provided for this purpose
- the position of the body of the user may be monitored, either by attachment of a sensor to the user, or again by monito ⁇ ng with an optical system All of these possibilities are intended to be within the scope of the invention
