Device for locomotion with anatomically adjusted joint axes

The present application deals with an invention in the field of

Sports Technology. It's about a device for locomotion and

in particular for rolling locomotion, and for using the heel walk or a combination thereof.

The invention relates to a device for rolling movement with front roller (1) and rear roller (2), frame (3), brake shoe (49) consisting of forefoot part (8) and lockable heel stroke part (9) with 2 transversely to the direction of travel joint axes , Brake arm (10), calf shell (11) and straps (24 to 27).

The prior art are rolling devices which either have a binding, in which one can climb with designated shoes and then form a joint, which form transversely to the direction of the agility of the football for the so-called bale impression in cross-country or are rolling equipment, where a shoe is mounted fixed or movable, which has a joint below the foot for the so-called ball impression.

There are also binding systems, as the invention shows, in which one can get in with normal shoes, but have no joint in the foot-ball area, but only in the ankle area.

Binding systems without foot-ball joint have the advantage that they provide a better grip against tipping and power transmission through the front wheel is better possible. Since cross-country skiers also want to train in the summer absolutely identical as in the winter, the task was based on, a binding for normal

To develop footwear, which not only in the ankle joint has a transverse to the direction of travel joint, but also in the foot-ball area.

The difficulty in this task was on the one hand to allow the flexibility in the foot ball area and on the other hand as little as possible to stability lose without the binding system becoming noticeably heavier. By making the foot-ball joint not below or in front of the foot, but with at least one joint laterally beside the foot, the movable one becomes

Heel lift generally shorter and less susceptible to torsional forces and can thus be made stable with less weight.

If the joints are attached next to the foot, this also has the advantage that the motion sequence in the footpad area is most identical to the foot anatomy and the toes are permanently in direct contact with the forefoot part

Rolling device is maintained. So that there is enough space for the width of the forefoot on the forefoot part, the heel stroke part is cranked at least at one joint.

An adjustable front lifting the forefoot part of the contact with the rolling device could be improved. The farther back the fulcrum of the foot-ball joint is located, the more advantageously the weight of the rolling device at the forefoot, if the weight of the rolling device on the joint in the ankle joint also partly comes to bear on the forefoot when lifting the foot.

To counteract the remaining residual load on the forefoot, it is advantageous to support the joint in the ankle area by means of spring force. Either you bring in the joint area a rod-leaf or coil spring or you can do this function with the help of a rubber band. Although by the relatively far back placed joint in the foot-ball area, the rolling device is almost balanced, it is advantageous to equip the joint in the foot-ball area with a Rückholfedervorrichtung. It is better if this return device is constructed adjustable in intensity. This Rückholfedervorrichtung is best done via a mini hand winch on the frame. A rubber band or spring extension is attached to the rear end of the heel stroke, then passed over a small pulley on the winch axis and returned via a deflection back to the winch axis. The winch axis is operated by hand and so the rubber or spring device is arbitrarily stretched and fixed by a ratchet element which engages the frame inside. By pressing the winch axis the ratchet element is released and the rubber or spring tension can thus be relaxed again. The pulley and the winch axis can also be apart.

Narrow joints are usually equipped for reasons of space only with plain bearing parts. Only an exact manufacturing accuracy achieved so far a joint result, which is absolutely backlash-free and yet smooth. Movable joints are subject to wear experience. Often makes then even with the originally exactly fitting joints a rattling and shaking of the hinged parts noticeable.

In order to keep a joint free of play and nevertheless smooth over a longer period of time, it is necessary that the sliding surfaces sliding towards each other run obliquely to the joint axis. If then these sliding surfaces are still held together permanently by means of clamping ring, the joint is up to a certain wear completely backlash-free and accurate. A narrow joint is often assembled and held with a screw. By moving the hinged parts there is often the risk that loosens this screw. To prevent this, the hinge part is fixed with the fixing pins through the fixing holes of the clamping ring in the fixing holes of the part to be taught and thus secured against rotation.

Tethers or ratchet straps are attached to bindings so far in the toe area, foot area and calf area transverse to the direction of travel for fixation of the foot. Often the lateral support in the ankle is not sufficient for poorly trained ankle muscles. In order to counteract the shaky holding situation in the binding, two straps or ratchet straps, called main straps for short, are crossed in the area of the ankle joint. Only Shoelaces are known to be crossed in the region of the ankle. If one end of a main harness is attached to the heel hub and the other end to the brake arm, the following happens during an ankle movement: If the lower leg is flexed forwards, the foot needs more space in the area of the ankle, and at the same time the band loosens over the boom harness. If you lean back, the main straps are automatically tensioned again. By crossing the main straps over the ankle joint axis, the foot is centered in the ankle area and supported against lateral tilting.

For rolling devices are often braked with various brake shoes on the entire tire tread. Austrian Patent No. 406642 shows a roof-shaped brake shoe which brakes on a small area of the tire sidewalls. The cooling takes place via the special material combination of precious metal and aluminum. In order to make the brake on the tire even gentler, the brake shoe is kept away from the tire in the middle of the most soiled tread in the area of the so-called tire protection zone and to the

Tire sidewalls adapted to the tire shape.

Rolling devices without steering are often performed in the recording of roles with exact holes, so that rolling devices run so halfway straight. If the take-up of the rollers is defined solely by the axle bolts, a rolling device rarely runs straight ahead without setting the grade outlet. In order to guarantee a track accuracy, the bearing bush, which are pressed laterally into the rollers in the ball bearing, tapered conically. This cone engages in a countersink on the inside of the respective axle bore on the fork of the frame. If you want to set the track despite this exact role leadership, it is sufficient if a bearing bush is designed eccentric, so by turning this

Bushing the rolling direction of a roll can be minimally changed.

A rolling device is either with heel stroke option or without

Heel lift possibility executed. Will you because of the different

Claims, steeper terrain or other running style, constantly choose between with or without Heelhubmöglichkeit, that was not possible. To meet these demands, a locking rocker is mounted on the side of the frame on which there is at least one control surface over which you can operate them from above by hand or a stick. In or on this locking rocker is a spring or rubber, with the one

Lockhook is switched and thus locks the heel aisle or unlocked. To this device for rolling locomotion also for soft

To make substrates useful, it is useful to provide openings on the frame (3) or install nuts to which rails with small, supported rollers can be attached. These rolling elements can also by means of

Plug-in system can be attached and removed.

As can be seen from Fig. 1, the frame (3) with front fork (4) and rear fork (5) is equipped. The front axle (1) is fastened via the front axle bores (6) with a quick release or axle bolt and the rear axle (2) at the rear axle bores (7). On the frame (3) of the forefoot part (8) fixed or fixed in the position to the frame (3) changeable fixable. The forefoot part (8) has at least one Zehengurtaufnahmen (16) and (17) on which by way of example in the form of an arrow of the toe strap (24) is attached. About the joints (12) and (13) on the forefoot part

(8) the heel stroke part (9) extending transversely to the direction of travel

Articulated joint axis. At the far end of the heel stroke part that does

Heel strap (32) the conclusion for the shoe holder. The heel strap (32) is passed through the heel strap opening (34) on both sides and then on the heel stroke part

(9) via a slot (33) adjustable in length or fix fixed. At the heel stroke part (9) is via the joints (14) and (15) of the brake arm (1 0) in a transverse to Directed direction of travel articulated joint axis. At least one Hauptgurtaufnahmen (18) and (19) are located on the heel stroke part (9) and at least one Auslegergurtaufnahmen (20) and (21) on which the main belt (25) of a Hauptgurtaufnahme (18) are located on the brake arm (10). to a

Outrigger belt retainer (21) and outrigger belt (26) from one

Auslegergurtaufnahme (20) extends to a Hauptgurtaufnahme (19) and is secured there. The main belt (25) and the boom belt (26) thus cross each other. The main belt (25) and the Auslegergurt (26) are shown only in the form of arrows, for example. At the rear end of the brake boom is the

Brake shoe holder (29) with the brake heat sink (28) and below the brake shoe (49) is mounted. To attach the brake shoe (49) is either at least one brake shoe screw (30) or only a plug-in system. Above the brake arm, the calf shell (1 1) adjustable in at least one direction fixed or fixed. To allow the adjustability of the calf shell (1 1) comfortable, a quick release is advantageous. For this purpose, however, a place for a nut in the calf shell (1 1) is required, this place is closed on the inside of the calf shell (1 1) with the nut cover (31).

As can be seen from Fig. 2, the brake shoe (49) on the tire (36) forms a

Tire protection zone (35) and on the tire side flanks hugs the

Brake shoe (49) to the shape of the tire (36) sitting on the rim (37). In the rim, the ball bearing (38), spacer (41), bearing bushes (39) with the Lagerbuchsenkonus (42) and Achsbohrung (40) can be seen.

As can be seen from FIG. 3, the bearing bushing cone (42) is centered on the bearing seat (43) of the bearing bushing (39) with respect to the center line (45) so that the bushing shank (44) is of the same thickness all round. The bush edge (47) can be either round or hexagonal.

As can be seen from Fig. 4, this bearing bush (39) is designed eccentrically. The bearing seat (43) is thus recognizable as an eccentric (46).

As can be seen from FIG. 5, the articulated parts hinge part (51), bearing ring (55), for example heel stroke part (9), clamping ring (58) with at least 2 clamping wings (57) and, for example, forefoot part (8) with screw (61) and nut (50)

held together. In the nut seat (53) comes while the mother (50) to lie. The bearing ring (55) is inserted into the hinge opening (56) press fit and can be replaced when worn. The joint opening (56) could also be designed as the bearing ring (55), so you could also save the bearing ring (55) - cheaper to manufacture. At least 1 fixing pin (52) engages

zusammengeschraubtem state by a fixing hole (59) in the clamping ring (58) in a fixing hole (60) in the example Vorfu ßteil (8) and secures the

Joint parts to each other against rotation. When screwed together, at least two clamping wings (57), for example, press the heel stroke part (9) and bearing ring (55) onto the joint part (51) and thus still hold such a joint play-free up to a certain degree of wear.

As shown in Fig. 6, only the rear section of the frame (3) with the rear axle bore (7) and on top of the heel stroke part (9) is shown. At least one locking hook (62) is articulated to the frame (3) in a joint axis running transversely to the direction of travel, and behind or at least one locking rocker (63) on the rocker bearing (65) on a joint axis extending transversely to the direction of travel hinged. In or at the

Locking rocker (63) is a rubber or spring (64) attached to the spring mounting (70). The spring (64) engages with the spring ring (71) slidably around the

Locking hanger (68) and can by alternately pressing on the

Operating surface (66) and (67) are moved. Here, the arrow (72) points to the rear control surface (66), as if one would press there with ski stick or by hand, thereby the locking hook (62) is pulled away from the heel stroke part (9) and released for the heel stroke.

As can be seen from Fig. 7, the arrow (73) simulates pressing on the front

Control surface (67), while the spring ring (71) on the locking hanger bar (68) is pushed down and immediately pulls the spring (64) at the bottom of the

Locking chopping (62) and is about the Hackenlagerung (69) on the

Heel stroke (9) held and thus the heel lift is locked. These

Fixing device would also work just as with a compression spring or rubber buffer instead of a tension spring, just in reverse function.
