Definitions
- the present invention generally relates to a cross-country ski with wheels, for the practice of cross-country skiing on non-snow-covered terrain.
- a conventional cross-country ski includes a central beam, a wheel respectively at the front and at the rear of the central beam and a device for fixing cross-country ski boots.
- cross-country skiing is practiced on roads with a relatively smooth surface. Indeed, a classic cross-country ski is not very suitable for wood paths or bumpy paths. The wheels are generally small, the risk they block is considerable.
- the skier takes the turns by lifting one of his skis to give it a different direction. To apply this technique on the fly requires some experience. In addition, it is not always suitable on a slightly rough ground because the skier hesitates to lift a ski.
- An object of the present invention is to provide an improved cross-country ski. This object is made by a cross-country ski as claimed in claim 1.
- a cross-country ski with wheels generally comprises a frame with a central beam and two supports for the wheels, one at the front of said central beam and the other at the rear.
- a front wheel is mounted on the front support and at least one rear wheel is mounted on the rear support.
- a cross-country ski with only one rear wheel has the advantage of having less resistance to advancement and thus allows faster locomotion.
- a classic cross-country ski includes a fixing device on the central beam to receive a cross-country ski boot.
- the fastening device allows the skier in particular to lift his heel, which constitutes an additional fundamental difference between a cross-country ski with wheels and a roller skate.
- the front support has a hinge arranged in front of said front wheel allowing the front wheel to pivot about an axis contained in the longitudinal and vertical plane relative to the cross-country ski.
- This axis may itself be substantially vertical or, as according to a preferred embodiment of the invention, be inclined forward with respect to the vertical by an angle of between 5 to 45 degrees, preferably between 15 and 35 degrees. .
- a cross-country ski with wheels according to the present invention therefore has the advantage of a directional front wheel.
- a wheeled cross-country ski even better adapted to a bumpy terrain advantageously comprises wheels with a larger diameter, for example from 10 to 15 cm.
- the front support may comprise a frame rigidly connected to the central beam with two lateral sides which pass on one side and the other of the front wheel and which join before it.
- the frame On the side of the central beam, the frame preferably has a width greater than central beam.
- the frame width decreases towards where the sides of the frame join in front of the wheel.
- the wheel itself is mounted on a wheel holder (eg a fork piece or link), which is connected to the frame by the hinge allowing the wheel to pivot.
- the lateral sides of the frame make it possible to limit the pivoting movement of the front wheel.
- the width of the frame decreases towards the front, the latter presents, seen from above, a shape resembling a drop or a triangle.
- the front wheel can rotate at an angle corresponding to the angle formed between the two lateral sides of the frame.
- the latter is preferentially around 15 degrees.
- the front support has a shock absorber at the joint.
- a shock absorber will be particularly appreciated on wooden roads or on deteriorated roads.
- the rear wheel support may also be equipped with a shock absorber.
- the wheels are advantageously inflatable.
- the wheel holding member may comprise stops cooperating with the two side sides of the frame. The pivoting movement of the front wheel is thus limited. The stops may be adjustable to allow the user to choose the maximum angle that can form the wheel with the longitudinal axis of the ski.
- the front support comprises recentering means for the front wheel.
- These recentering means may resiliently oppose the inclination of the front wheel relative to the longitudinal axis of the ski and pull or push in the position where it is aligned with the ski.
- the recenter means may be arranged at the joint, but in a preferred embodiment of the invention, the recentering means comprise springs arranged between the frame and the fork member of the front support. It should be noted that if the axle of the articulation of the front wheel-holding piece is inclined forwards, the user can control the steering and also the refocusing of the front wheel by changing the lateral inclination of his skis.
- the frame may comprise reinforcing means, such as sheets or rods, passing above the front wheel.
- a first embodiment of the present invention also provides a brake of a particular design for a cross-country ski.
- the proposed braking device comprises a braking pad that can act on the rear wheel (s), a brake cable and a brake control lever.
- the latter is arranged so that it can be actuated by the shin of a user of cross-country skiing.
- the brake control lever Upon actuation of the brake control lever, the brake cable is tensioned to engage the brake pad in a braking position.
- An improved brake for a cross-country ski is provided by the present invention.
- the brake allows the user to brake without having to move into an unstable position. He does not need to use his hands to operate the brake. The fact that the skier can use his ski poles to balance out significantly reduces his risk of falling.
- the brake control lever can be actuated by a movement in front of the shin of the user.
- the skier flexes his knee and his shin pushes the brake control lever forward.
- the user therefore lowers its center of gravity which gives it greater stability.
- the brake control lever can tilt forward when the skier raises the heel without the brake pad is thus engaged in a position of braking.
- the skier lifts the heel of the foot momentarily at the back. The leg thus descends obliquely to the rear and is thus likely to actuate the brake control lever if it does not follow the movement of the leg.
- the brake control lever can tilt forwards when the bead is raised without engaging the pad in a braking position, the skier can ride regardless of his or her touching the brake control lever.
- the braking device may include means for reducing the tension of the braking cable when the skier's heel is raised.
- the braking device comprises a spring which, when the brake control lever is not actuated, holds the brake pad in a rolling position and exerts a tension on the braking cable to straighten the lever. brake control.
- the rolling position is defined as the position of the parts of the braking device which does not prevent the wheel from rotating freely.
- the braking device comprises a brake lever, a braking pad, a braking cable and an actuator, said braking lever carrying the braking pad and being connected. to the actuator by the braking cable, the actuator can be moved into a braking position in which it pulls the braking cable by movement forward of the knee of the skier.
- this actuator includes a winder which is attached to a strap which can be attached to the skier's knee and unrolled from said retractor.
- the actuator is in this case fixed to the frame so as to be rotatable relative to a transverse horizontal axis, the strap causing a tilting of the actuator in the braking position when it is essentially unwound, that is to say say when fully unwound and / or, in the case where the retractor comprises a strap return spring, when the force transmitted to the actuator by the return spring exceeds the initial tension of the braking cable.
- the braking device comprises adjustment means allowing the skier to adjust the length of the strap according to his needs.
- the braking device of this embodiment essentially has the advantages of the embodiment described above. Compared to the latter, however, it requires fewer moving parts and forms a simpler mechanism therefore potentially cheaper to manufacture.
- the word strap designates in this context any kind of cable, string, etc., preferably substantially inelastic.
- the rear wheel support comprises a truck (axle eg for skateboard) damping by elastomer or, preferably, by springs.
- the frame preferably comprises a portion raised relative to the central beam to which the truck is attached.
- the raised portion is connected to the central beam via a curved or oblique transition piece, which confers, in addition to an elegant appearance to the ski.
- a cross-country ski with a brake as described herein does not necessarily need to be equipped with a directional front wheel.
- the total length of the cross-country ski is preferably between 60 and 90 cm, and more preferably between 60 and 70 cm.
- a short ski has a lower moment of inertia, which facilitates the practice of the sport and increases its attractiveness. With the swivel wheel, the directional stability of the ski is not jeopardized by the shortening of the ski.
- the cross-country ski may have a mechanism for varying the length, e.g. ex. a beam central telescopic. Each user can thus adjust the length of the ski according to his own needs.

- Figure 1 shows a longitudinal view
- Figure 2 a horizontal view of a support 10 of the front wheel 12 of a cross-country ski wheel according to a first embodiment.
- the support 10 comprises a frame 16, a fork piece 18 and a hinge 14, arranged at the front of the wheel 12, which connects the frame 16 to the fork piece 18.
- the wheel 12 is mounted on the fork piece so as to freely rotate about its axis 34.
- the hinge 14 With the hinge 14, the fork piece 18 can, together with the wheel 12, pivot about the axis 20 passing vertically by the hinge 14.
- the piece fork 18 is held movable relative to the frame 16 by ball bearings 22, 24.
- the frame 16 is suspended from the fork member by means of a spring 26.
- a pin 28 is housed on the axis 20 of the hinge 14 and attached to the fork member 18. At the lower end, the pin 28 has a thread for screwing a nut 30.
- the ball bearing 24 rests on the nut 30 and serves as a support for the spring 26
- the other side of the spring 26 bears against the ball bearing 22 and presses it against the upper wall 1e of the cylindrical housing 32, which is integral with the frame 16.
- the ball bearing 22 serves as a guide for the pin 28, which can perform a reciprocating movement relative to the cylindrical housing 32 to dampen shocks.
- a stop 36 comprising for example a polyethylene or Teflon washer, is arranged between the upper wall of the housing 32 and the fork piece 18, to prevent these two parts from colliding when the wheeled ski is not or little loaded.
- the abutment 36 advantageously comprises another ball bearing for reducing the friction between the cylindrical casing 32 and the fork piece 18.
- the wheel 12 is preferably an inflatable wheel with a diameter of 10 to 15 cm. A higher wheel size makes it easier to ride on uneven ground where wheels with a normal diameter (6 to 8 cm) would block. To avoid that with wide wheels the skier is too far from the ground, the frame 16 is located below the axis 34 of the front wheel. It should be noted that the greater the distance from the ground to the foot, the more difficult it is to remain balanced on the ski. In addition, the risk of the skier stepping on his foot during a fall increases with the distance from the ground. Seen from above, the frame 16 has a shape resembling a drop. The width of the frame 16 at the rear of the wheel 12 is greater than the width of the central beam 15. The pivoting movement of the wheel 12 is limited by the angle formed between the two lateral sides of the frame 16. This angle is preferably between 10 and 15 degrees.
- the fork piece 18 goes down from the hinge 14 to the axis 34 of the front wheel 12. Beyond the axis 34, relative to the joint, the arms of the fork piece is extend to form abutments 36. These abut against the frame 16 to limit the pivoting movement of the wheel 12 about the axis 20.
- the abutments 36 may comprise a buffer of elastic material to absorb the shock when the stops hit the frame 16.
- springs 38, 40 are arranged on both sides of the wheel 12 between the fork piece 18 and the frame 16. In a right turn, the rear of the wheel 12 leaves towards the left. The left spring 38 is compressed and the right spring 40 is stretched. The springs 38, 40 therefore contribute to recentering the wheel 12 until it is again aligned with the central beam 15.
- Figures 3, 4 and 5 show a longitudinal view of the rear part of the cross-country ski with wheels.
- a support 41 of the or rear wheel 42 is fixed to the central beam 15.
- the cross-country ski has a braking device with a brake pad 44, a braking cable 46 and a brake control lever 48.
- the brake control lever 48 is so arranged on the central beam 15 of the frame that it allows the skier to brake with the tibia 64.
- the lever 48 is mounted on a substantially horizontal axis 52 and transverse, which allows the upper part of the lever 48 to pivot forward.
- the shaft 52 is housed held in a support piece 66 so as to slide obliquely relative to the direction of the bearing.
- the support piece 66 has holes oblong 68 inclined relative to the horizontal in which the axis 52 can slide.
- the axis 52 is fixed to the support piece 52, and the oblong holes 68 are present on the brake control lever 48.
- the attachment 70 makes it possible to fix a shoe cross-country skiing 72 to the central beam 15 movable about an axis 74 located at the front of the shoe 72 so that the skier can lift the heel.
- the attachment 70 is further provided with a deflection member 76 which deflects the braking cable 46 to an attachment point 54 on the brake control lever 48.
- the cable 46 is deflected by a pair of pulleys deflection 56 and returned to the rear wheel 42 through a hollow space in the central beam 15.
- Another deflection pulley 58 returns the cable 46 to a brake lever 60, which comprises the brake pad 44.
- the skier To brake, the skier flexes the knee while keeping the heel in contact with the central beam 15 (Fig. 3).
- the tibia 64 then pushes the top of the lever 48 forward.
- the attachment point 54 is moved forward which increases the distance between the deflection member 76 and the attachment point 54.
- the axis 52 slides obliquely forward and the boss 78 of the lever brake control pushes on the cable 46.
- the braking cable 46 is stretched.
- the pulleys 58, 56 transmit the tension of the cable 46 to the brake lever 60 and the brake pad 44 is brought into contact with the rear wheel 42.
- a spring 62 between the brake lever and the support 41 is stretched when the brake is actuated.
- this steering device comprises a means for limiting the inclination of the ski and the steering.
- FIGS. 6 to 11 A preferred embodiment of the invention is illustrated in FIGS. 6 to 11.
- the cross-country ski with wheels 100 comprises a chassis with a central beam 115, a front wheel support 110 and a rear wheel support. 141.
- the central beam 115 is formed of a hollow aluminum rectangular profile, connected to the wheel supports 110, 141 by screws or welding.
- the wheels include tubular tires with a width of 30 mm and a diameter of 122 mm.
- the wheels, or at least one wheel can be equipped with a rollover bearing, which will facilitate the practice of the sport.
- the front wheel support 110 comprises a frame 116, a fork piece 118 and a hinge 114, arranged at the front of the wheel 112, which connects the frame 116 to the fork piece 118.
- the frame 116 is is in the form of a cage with reinforcing plates 117 passing over the front wheel 112.
- the junction 119 of the frame 116 with the central beam 115 is formed by interlocking. The holding in position is performed by screw-tightening through the central beam 115, with inserts in the frame 116.
- the front wheel 112 is mounted on the fork member 118 so as to be freely rotatable about its axis 134.
- the fork piece 118 may, together with the wheel 112, pivot about the axis 120.
- the pivot axis 120 is contained in the vertical longitudinal plane of symmetry of the cross-country ski 100 and inclined 30 degrees to the before. Because the pivot axis is inclined forwards with respect to the vertical, the front wheel 112 tends to align with the ski when the skier keeps the central beam 115 horizontal, that is, say when he does not impose lateral inclination. Stoppers 136 arranged on the axis of rotation 134 of the front wheel 112 limit the pivoting movement of the front wheel 112 because they bear on the lateral sides of the frame 116.
- the fork member 118 comprises a cylindrical housing 180 arranged around the axis 120 of the hinge 114.
- the carcass 180 houses a shaft 181 fixed to the frame 116 of the front wheel support.
- the shaft 181 ends in a stop 182, formed, in this embodiment, by a thick washer screwed onto the shaft 181.
- the cylindrical casing 180 has, on the lower side, a portion 183 with a reduced internal diameter forming a stop.
- the rotation of the shaft 181 in the cylindrical carcass 183 is facilitated by a ball bearing 184 and a bearing 185 housed between the abutment 183 of the carcass 180 and the shaft 181.
- an elastomer ring 186 is arranged between the ball bearing 184 and the stop 182 of the shaft 181.
- the hardness of the elastomer ring 186 can naturally be chosen according to the weight of the skier.
- the shaft 181 and the cylindrical casing 180 are preferably made of steel. Lubrication of the assembly is made possible by the passage of screw 187, which is closed off by a plastic cover 188.
- the rear wheel support 141 of the cross-country ski 100 includes a truck 145, on which are mounted the Rear wheels 142. Trucks suitable for use in the present invention exist on the market as standard parts and do not in principle require a detailed description.
- the distance between the rear wheels is 105 mm.
- the portion 143 of the rear wheel support 141, through which the truck 145 is fixed to the chassis, is raised relative to the central beam 115.
- the junction between this portion and the central beam comprises an oblique transition piece 147, preferably made in the same material as the central beam 115, and lateral reinforcing plates 149 which increase the stability of the junction.
- the cross-country ski is provided with a braking device acting on the rear wheels.
- the braking device comprises brake pads 144 mounted on a brake lever 160 which serves to put the brake pad 144 in contact with the wheels 142.
- the brake lever 160 is actuated by a braking cable 146 passing through a sheath below the oblique transition piece 147.
- the brake cable 146 is attached at its other end to a brake actuator 190 placed on the central beam 115 at the rear of the area where the skier's foot rests.
- the brake actuator 190 can rotate on a transverse horizontal axis 191 to pull on the brake cable 146 and actuate the brake.
- the actuator 190 is connected to the user's leg by a strap 192 attached, on the one hand, below the knee of the skier and, on the other hand, to the actuator.
- the strap is fixed on the actuator by means of a winder 193.
- the strap When the skier pulls on the strap 192, the strap first unrolls without the actuator 190 pulling on the brake cable 146. If the strap 192 is fully unwound, pulling more on the strap 192 causes the actuator 190 to tilt about the axis 191 and thus the actuation of the brake.
- the retractor 193 is provided with a spiral return spring 194 to keep the strap 192 stretched at all times and thus prevent the latter from dragging on the ground or interfering with other components of the cross-country ski with wheels 100.
- the skier raises the heel of the foot of the leg momentarily to the rear.
- the length of the strap 192 and the wound length of the strap 192 are adjustable so that the heel lifts do not cause braking. If he wants to brake, the skier bends his knees and therefore pulls more on the strap 192 than if he raises the heel.
- the wound length of the strap 192 is adjusted so that the strap 192 is fully unwound before the skier's knee is in its extreme position during braking.
- the brake is reliably actuated when the skier takes the braking position and, secondly, that the brake is triggered only under this condition.
- the proper wound length of the strap and the total length of the strap can vary from person to person. Finding these good lengths for an individual is however routine work for the skilled person.
- the braking device comprises adjustment means for adjusting these parameters.
