Definitions
- Electric walking and driving drive The invention relates to an electric walking and drive drive to move faster and easier on foot.
- various proposals for drives of skis For example, US 3,964,560 shows a ski whose entire rear part is formed behind the heel binding as a caterpillar drive, which is motor-driven and should turn on idle when departing.
- US 2 625 229 shows a drive with a caterpillar drive under the front part on the one hand and a caterpillar drive under the rear of the ski on the other hand, which are connected to each other via a roller chain and driven by a gasoline engine, which is carried on the back of the skier as a backpack.
- the power transmission takes place by means of flexible strings.
- these drives are intended for skis throughout.
- the object of the present invention is to provide an electric walking and driving drive, firstly to make walking for sporting reasons more attractive, second, to significantly increase the radius of action when walking, and thirdly, to a completely new motion experience Going to bid. Especially in a version as a climbing aid for touring skis This stepping and traction drive makes it easier to climb with skis and make this ascent a new, attractive motoring experience.

- Figure 1 shows a first example of this walking and traction drive 1, which can be used on solid ground, such as on asphalt roads, nature trails or trails, seen from the side.
- a walking and drive 1 For each foot or shoe 36 of a user such a walking and drive 1 is provided. He has a chassis with rectangular, flat top 47 of at least 7cm wide and at least 40cm in length. Then the shoe 36 is turned off. A cross-country ski shoe 36 is used, and at the front a cross-country binding 48 is mounted so that the shoe 36 can be connected at its tip to the chassis, in the same way as on a cross-country ski, so that the heel of the shoe 36 is lifted and the shoe can be swung up to go up. From the two longitudinal edges of the top 47 side walls 2 extend downwards.
- a deflection roller 4 is mounted, which has a freewheel, so they can only rotate forward, but never backwards, and also zuhinderst a guide roller 7 is mounted, which may be the output roller 12 of an electric motor, or this deflection roller 7 is also driven by a built-in between the side walls 2 gearbox of a separate, also installed between the side walls 2 low-voltage electric motor, for example, 12 or 24 volts operating voltage.
- a battery 30 is placed for the electric motor, so that it is not worn by the user, but rather by the walking and drive 1 itself.
- To the two pulleys 4,7 and the rollers 5 performs a belt 16 as a running and drive belt.
- a toothed belt can also be suitable as a drive belt.
- the guide rollers 5 in the side walls 2 in the longitudinal direction of the walking and traction drive 1 can be slidably mounted and clamped, or it serves a tensioning roller not shown here as shown in Figure 6 with numeral 6 and is designated.
- the engine is controlled by a separate electronic control unit, which is attached to the handles of Ski or walking sticks can be actuated, as explained for Figure 13. This allows the engines to be switched on, the drive mode to be set and the speed regulated, and also braked in a special version for driving on slopes.
- a brake can serve a brake pad, which is electrically and finely adjustable from the inside to the remaining free part of the front guide pulley 4 slidably or pivotally.
- the brake pad may also act on the inside of the drive belt via a toggle mechanism to increase the braking force.
- These brake pads are operated, for example, via Bowden cables 56 or hydraulic hoses, to which the walking sticks are equipped with brake levers 55 like those of a bicycle. This allows the braking force to be finely dosed.
- the walking and drive 1 is shown with the shoe 36 lifted.
- the operation or use of walking and traction drive 1 is as follows: In a simple mode of operation, the two walking traction drives 1 for the two feet or shoes 36 are driven at the same speed, for example at about walking speed, ie about 4 to 5 km / h.
- the user stands on the drives and drives forward as on sliding skis and is equipped with extended hiking sticks in the manner of cross-country ski sticks. He can now superimpose this basic speed with his own active walking by advancing on solid ground as usual.
- the contrasting foot pushes the respective walking and driving drive 1 by automatically disengaging the electric motor when it is over-turned, and thanks to the freewheel of the front guide pulley 4 in a natural way forward, with about walking speed relative to already moving at a rapid pace other walking pace. and traction drive 1, on which rests the other foot.
- the now parked or patch foot drives with his walking and drive 1 only at a fast pace forward, and the now lifted foot pushes his walking and drive 1 at a rapid pace on the other past forward, opposite the ground but with double walking speed. All in all, it is a natural progression, but at twice the speed opposite the ground than in the ordinary stride without this drive.
- the basic speed can be regulated, so that higher tempos can be set.
- the user's pace can be superimposed at its own speed, so that overall it is possible to move for example at 10 to 20 km / h and in experienced people with even higher speeds.
- the motors may be controlled so that, as soon as a foot or shoe 36 is lifted from the top 47, they switch to a higher driving speed until the shoe 36 back to the top of the walking and driving drive is put on.
- This can be done by a magnetic switch detects the lifting of the shoe 36, which then initiates the increase in the speed of the electric motor in question.
- the controller may be programmed to adjust the speed history over the period of time the shoe is lifted off the natural course of motion, thus resulting in a natural stride in this mode of operation, but with minimal effort. All in all, this walking and traction drive gives you an unprecedented, attractive feeling of movement, as well as a speedy progression, so that inclines and longer distances can be handled much more effortlessly.
- FIG. 3 shows the walking and traction drive 1 in a perspective view obliquely from the front.
- the width of the top is adapted to the width of a cross-country boot, but may also be made wider to provide better grip about the longitudinal axis of the drive.
- Behind the shoe 36 there is space for the inclusion of a battery 30, such as each a battery of 200 to 400Wh capacity as they are used for electric bicycles.
- FIG 4 shows the walking and traction drive 1 spanned on a ski 17, wherein it extends over the area below the ski binding, that is from below the toe binding 15 to behind the heel binding 25.
- the walking and drive 1 consists of a guide frame, which on both sides of the ski 17 each have a side wall. 2 , 3, wherein here the right side wall 3 is not visible.
- the drive components are housed, as will become apparent from the other figures.
- a plurality of rollers are mounted between the two side walls 2,3, around which a belt of approximately the width of the ski in the binding area is guided as an adhesion and drive belt. This belt can be driven by an electric motor.
- the guide frame is lower at the front than at the rear and thus forms a wedge below the ski 17, so that the ski is less inclined in slope than the terrain.
- the walking and driving drive 1 can have an extended upper side of its guide frame with threaded bolts projecting upwards in these extensions, which can be inserted from below through the holes 13, 14 in the ski 17 and then on the top of the ski 17 are screwed with a lock nut.
- the walking and drive 1 is stably braced with the ski 17. It is clear that the walking and drive 1 must be as light as possible in order to avoid unnecessary weight.
- the guide frame with its side walls 2,3 is therefore preferably made of aluminum sheets or even of a suitable lightweight material such as synthetic para-aramid fiber composite panels (Kevlar®), titanium, carbon fiber reinforced plastic plates or similar material.
- the walking and drive 1 is shown in Figure 4 schematically without side wall 2 of the guide frame and is clamped on the ski 17.
- a pulley 4 At the very front of a pulley 4 is arranged, which advantageously has a freewheel hub, so that the roller 4 can rotate in the figure shown only in the counterclockwise direction. She has a tooth on the outside.
- the next few rollers 5 are rollers that can rotate freely in any direction and are well stored, so they offer as little rolling resistance as possible. You can also set up a toothing have their tread so that they fit exactly to the wound strap 16, but they may as well have a smooth running surface.
- the rearmost arranged roller 7 contains in the example shown an electric motor 12 with a reduction gear 10, for example a planetary gear. Before this role 7, a support roller 6 is mounted. The belt 16 is guided around the end-side rollers 4, 7, then backwards under the rollers 5, and after looping around the rear end-side roller 7 with the electric motor 12 forward under the support roller 6 and then on the upper side of the front pulley 4 led.
- This belt 16 forms an adhesive tape, which comes to lie with its toothed or otherwise somewhat structured adhesive surface on the snow, and forms on its other side a toothed drive belt, that is a toothed belt, which wraps around the roller 7 with its drive surface, in which case the Roller 7 by the drive from the electric motor 12 via the planetary gear 10 acts as a drive roller.
- the endless belt 16 therefore moves counterclockwise in the image when in action.
- a drive belt 16 a commercially available double-sided toothed belt can be used.
- Figure 6 shows this walking and traction drive according to Figure 4-5 shown on the ski 17 schematically without side wall 2 of the guide frame from the left side, so that only the rear, right side wall 3 is visible in the image, to release the Looking at the rollers 4, 5, 6 and 7 just described.
- all rollers 4-7 are equipped with a toothing on their running surface. This toothing engages in the toothed belt 16, which has a toothing on both sides. Her teeth are driven by the teeth on the roller 7, and the belt 16 then passes under the support roller 6 through forward, there around the guide roller 4 around and afterwards under the Rollers 5 back to back and there from bottom to top to the drive roller 7 around.
- the support roller 6 ensures that the belt 16 is guided undisturbed and free to the guide roller 4, without the running in the opposite direction portion of the belt 16 to be able to touch.
- the rollers 5 serve to distribute the weight of the skier on the drive belt 16 evenly. In addition, they prevent that the belt 16 can touch the upper, forward-running section when driving with the walking and driving drive 1 over a terrain crest.
- a ramp 24 articulated in the form of a hollow wedge of aluminum sheet or lightweight construction material.
- the ramp 24 is folded out into the position shown and clamped in this position with the clamping bracket 1 1 to the underside of the ski 17.
- the walking and drive drive continuously and gently on the snow.
- dismantled walking and driving the ramp is folded 180 ° on the top of the guide frame, so that the walking and driving a total of no longer than measured from the front pulley 4 to the rear drive roller 7 and thus easily fixed to the departure for backpacking can be supplied or in there sewn special bags can be supplied.
- Figure 7 shows this walking and traction drive 1 shown separately, without side wall 2 of the guide frame, to release the view of the rollers 4-7, in a perspective view. You can see the teeth on all rollers 4-7, which are advantageous ball bearings, for a minimum rolling resistance.
- the deflection roller 4 or optionally the drive roller 7 can be moved with its axis in the guide frame transversely to its axis in the longitudinal direction of the guide frame and clamped to tension the belt 16.
- the belt 16 is shown here smooth. In fact, however, it is advantageous to have a toothed belt with a toothing matching the toothing on the rollers 4-7 in order to ensure optimum transmission of power from the drive roller 7 to the belt 16.
- a belt could be used which has a soft, rubber-elastic coating as the drive side and has a coat on the adhesion surface, such as a conventional adhesive tape for touring skis.
- the rubber side then runs taut over the teeth or over a soft rubberized, textured surface of the drive roller 7, which also produces a sufficient driving force.
- On the upper side of the walking and driving drive 1 in the example shown forms a support surface 8 for the ski 17.
- This support surface 8 is slightly surmounted laterally upward by side guides 9, so that for the ski engineer modiffraction a side guide is formed. In individual cases it may be sufficient that only in places upstanding ears are formed, between which the ski is guided and held. These ears can also be made adjustable in the distance, as previously adjustable jaws of a ski binding in their clear width were adjustable, between which then the ski boot was held.
- Figure 8 shows the walking and drive 1 separately seen from the side, without the side wall 2 of the guide frame, so that only the rear or right side wall 3 is visible to release the view of the rollers 4-7.
- the belt 16 always runs in the direction indicated by arrows. This is ensured by a freewheel hub, which is advantageously installed in the front deflection pulley 4, so that one can never roll back with the ski on the belt 16.
- the drive roller 7 houses a high-speed low-voltage electric motor 12 of, for example, 36 volts whose speed is translated from 10 ⁇ 00 to 20 ⁇ 00 rpm via a reduction gear, for example via a two-stage spur gear or, as in the example shown, via a planetary gear 10 to a lower speed and its torque is then delivered to the drive roller 7.
- a high-speed low-voltage electric motor 12 of, for example, 36 volts whose speed is translated from 10 ⁇ 00 to 20 ⁇ 00 rpm via a reduction gear, for example via a two-stage spur gear or, as in the example shown, via a planetary gear 10 to a lower speed and its torque is then delivered to the drive roller 7.
- Figure 9 shows the walking and traction drive 1 without ramp 24 seen obliquely from above.
- the lower edges 18 of the side walls 2,3 slightly overhang the inboard belt 16 so that, like knives or crampons, they engage the snow and provide the necessary lateral support when, for example, a slope is traversed.
- the figure 10 shows an alternative variant for clamping the walking and traction drive 1 on the ski, instead termedspannen it by means of threaded bolts and lock nuts or screws on the ski.
- a wedge 19 is placed forward sloping on the ski surface in front of the front ski binding 15 so that it is present at the ski binding 15 and can not move on the ski backwards.
- a wedge 20 is placed sloping down on the ski surface.
- a clamping bracket 21 is hung from the front end of the guide frame obliquely forward on the front wedge 19 and the rear end of the guide frame another clamping bracket 22 obliquely behind the rear wedge 20.
- At the end of the rear wedge 20 is stretched by means of a tensioning device with adjustable tension buckle 23 on the top of the rear ski region to the rear, to the hook 46, which is hooked at the rear end of the ski.
- the walking and traction drive 1 is fed and held securely on the underside of the ski.
- a hollow wedge 24 of lightweight construction material is articulated to the same, which is pivotable there about the axis 42. With its front end, it is then on the Skigleitbelag, and when dismounted walking and drive it can be swung for the departure by 180 ° on the same and the walking and drive can be stowed in this form in or on the backpack.
- Figure 1 1 shows an alternative variant of the stretching of the walking and drive 1 on the ski 17.
- the walking and drive 1 is clamped under the binding area of the ski 17, he is plugged from behind on the ski , by means of a guide with bracket. It therefore no longer extends all the way to the front binding 15.
- a hollow wedge 24 is hinged to the walking and driving drive 1, which extends to the ski tip and thus forms a plane together with the adhesive tape of the walking and driving drive 1.
- the hollow wedge is braced at the front over a bracket with the ski, so that its front end rests fed on the ski cover leaking on the same.
- the whole ski length is used as a support surface.
- the hollow wedge 24 is folded over by 180 ° on the dismantled walking and traction drive 1, as indicated by the arrow, so that the walking and Travel drive about half as long as the ski fails.
- the mounting of the walking and driving the ski takes in all variants presented hardly a minute, dismantling also. All elements of the walking and traction drive can be easily stored in a backpack. This walking and traction drive is also effective in deep snow and also ensures optimum lateral support on hard snow.
- the side plates 2, 3 or side walls 2, 3 of the guide frames act as harsh iron.
- Figure 12 shows a particularly simple way to attach the walking and drive on a touring ski 17.
- a plate is mounted, which laterally downwardly projecting wedges 49.
- the side walls 2 of the walking and traction drive 2 are front provided with upwardly projecting counter wedges 50.
- Rear side walls 2 are equipped with oppositely directed wedges 51, which project slightly upwards the side walls 2.
- a plate 52 which also the battery 30 can be placed or pushed from behind on guide rails, is equipped at its front end with lateral counter wedges 53. These can be hung on the wedges 53 of the side walls 2.
- the batteries 30 for the two electric motors can be carried in the backpack, as close to the cross or body center of gravity, or with advantage they are attached to the top of the skis and carried.
- the electronic control unit can also be carried either in the backpack or be removed wegappelbar on the ski upper side.
- the on and off as well as the power regulation can over the handles of the associated Ski poles done.
- the grips may include, for example, buttons 26 and small wheels 27 of potentiometers as shown in Figure 13, or with buttons 28 for + and - to increase or decrease the performance of the wheel hub motors 12 on the two skis 17.
- the grips may do so be connected via a respective cable 29 to the electronic control unit, which is located in the battery in the backpack, or on the top of the skis. And from there cables also lead to the electric motors 12 of the drive rollers for their power supply.
- the control is wireless from the handles on the ski poles to the electronic control unit, by means of a radio link.
- the power is regulated.
- the ski standing in each case during the ascent when stepping is pushed forward by this drive unit 1, at about walking pace, and at the same time the other ski is pushed forward by the drive with double speed, as follows: So that the unloaded ski not with great weight and load must be retraced - he is heavier than a ski without this drive unit - a circuit can be provided, which responds to the load of the ski.
- a pressure sensor is mounted on the ski so that the parked heel of the ski boot comes to rest on it. If the ski is loaded by the heel, the pressure sensor is loaded and switches the operating mode of the electric motor to standard speed.
- the controller shifts to twice the speed.
- the ski is pushed forward, as if it were pulled forward by striding alone until it is loaded again.
- the additional weight of the walking and driving drive for the Skitouren réeller is more than compensated.
- the control switches back to normal drive speed, ie at walking pace. Higher basic speeds are possible, depending on the practical exercise and the strength of the motors used. It turns a kind of "Moonwalk", from the side Watch as if someone on a conveyor belt, which moves in the direction of stride, additionally advances.
- the electronic control is advantageously memory programmable.
- control is programmed accordingly in order to come as close as possible to the natural biomechanical movement of the ski tour operator.
- the control unit can be programmed to first "copy" the sequence of motions of an individual ski touring gear by pacing the engine off, feeding the electronic memory unit with the voltage that the motors deliver with the typical speed curve of their type
- the speeds of the motors 12 associated with the determined angles are thus detectable so that the speed curve of the motors 12 of the two skis can be programmed as a function of the detected angles
- the walking and driving drive can imitate an individual biomechanical movement of a ski touring gear, so that a natural as possible scream en is ensured.
- the batteries 30 are advantageously secured as shown in Figure 14 on the front ski of a bracket 45 to which the battery as is shown pivotally mounted with the arrow. Nevertheless, the ski boot for walking in the usual way with the heel can be lifted off the ski, as indicated by the arrow. Thus, the battery 30 must not be carried in the backpack, but is carried by the ski and hardly felt.
- the drive units are stowed in the backpack, and the batteries 30 are reversed in the brackets 45 by 180 ° and then pivoted on the front skis in the brackets 45 and fixed so that they come to rest over the instep of the ski boot, like that is shown in FIG.
- this walking and drive 1 can also be designed as a combinable walking and drive 1, which can be used both on hard snow-free ground with cross-country boots and is provided here for a cross-country binding, and a Adhesive tape, which is suitable for these purposes, and then rebuilt for touring skis by simply disassembling the long run and putting down another strap suitable for snow adhesion.
- this walking and traction drive can then be used for summer and winter operation.
