Definitions

  • the invention relates to the field of skating such as roller skating, skating in line or ice skating.
  • the invention relates to a skate comprising a shoe articulated on a chassis to allow a heel lift and thus improving the practice of skating on the sliding surface.
  • the articulated pads are already known from the prior art, especially in the ice skating, where their effectiveness is now recognized in skating speed. It has been found that traditional skates limit the extension of the ankle at the time of the push to avoid catching the tip of the skate with the sliding surface. Suddenly, this limitation of movement causes a loss of power. In addition, the contact time with the gliding surface with each stride is decreases.
  • a skate structure in which the shoe is articulated on the chassis allows the heel to come off relative to the chassis and thus frees the ankle. The skater can lengthen the ankle without risk of planting the point in the surface of slips. The contact with the sliding surface is also kept longer while the ankle is still extended.
  • Patent application EP 0 778 058 A2 relates to an inline skate whose the shoe comprises two rigid half-shells, one front, the other rear, articulated together by a pivot arranged transversely.
  • the front half-shell is rigidly fixed to a chassis comprising a series of aligned wheels.
  • One of the disadvantages comes from the fact that the shoe has a rigid type structure having tends to be heavy, uncomfortable and hot.
  • the joint is also subject to significant efforts from the increase in the lever arm during the extension of the shoe around the axis of rotation.
  • the invention relates to an inline skate comprising a chassis on which is mounted a series of wheels, and a shoe connected to the front only of the frame so as to allow the heel of the shoe to be raised from the chassis during skating.
  • the shoe includes a flexible upper that provides comfort, lightness and flexibility.
  • the rod includes a front portion provided with a base of sole fixedly connected to the chassis, and a portion of rigid rear sole, independent of the front portion of flexible rod, and which is hingedly connected on the chassis. By being connected to the chassis, the joint provides good rigidity in torsion while providing sufficient freedom in extension of the ankle.
  • the shoe consists of a subset reinforcement comprising a heel counter fixed to the portion back of rigid sole and a collar surrounding the ankle and connected on the sides of the heel counter.
  • a subset reinforcement comprising a heel counter fixed to the portion back of rigid sole and a collar surrounding the ankle and connected on the sides of the heel counter.
  • the rigid rear sole portion is articulated on the chassis around an axis of rotation substantially transverse and parallel to the chassis support base.
  • the articulation is thus arranged to favor a thrust perpendicular to the chassis and participate in the torsional rigidity of the assembly when extending the ankle.
  • the rigid rear sole portion comprises a lower support surface on the support base of the chassis.
  • the portion rigid rear sole is coupled to an elastic return means opposing a elastic resistance torque tending to bring the lower bearing surface closer to the chassis support base when raising the heel.
  • the elastic return means comprises a elastic bending plate housed in overlap of the flexible front portion and the rear portion of the sole on which it rests to deform in flexion.
  • the front portion is connected to the base chassis support by fasteners located in the toe area of the shoe. Attaching the front of the shoe to the chassis resolves the problem related to diving the forefoot on the sliding member (blade or wheels) or the sliding surface which can thus generate friction. It also determines an axis of rotation disposed behind the front portion which is fixed; this having for advantage of concentrating the pushing efforts in a predetermined location, particular in the vicinity of the metatarsals, while a moving axis diffuses the forces of thrust; which results in a loss of yield.
  • the flexible rod comprises in the region of the plane vertical passing through the articulation axis sufficient flexibility allowing bending of the stem.
  • the shoe 1 illustrated in FIG. 1 comprises a shoe base 2 and a train roller 3 on which the shoe is mounted.
  • the running gear means the part of the shoe which ensures contact with the sliding surface. It usually includes a chassis 4 formed by an inverted U-shaped profile between which extends a series of wheels 5; which are individually arranged in an aligned configuration in a main longitudinal extension direction.
  • the shoe can have different configurations depending on the specific disciplines intended for him. Nevertheless, the invention finds a advantage of using a shoe with a flexible upper as opposed to shoes with hull derived from alpine skiing.
  • the upper of the shoe means the shoe part surrounding the user's foot.
  • the rod therefore comprises a front portion 20 covering the forefoot, including the toes, and a portion rising 21 which surrounds the ankle and extends more or less high in the vicinity of the calf.
  • the flexibility of the upper is mainly provided by the choice of materials appropriate. Such materials provide strength, comfort and breathability. They can be chosen from fabrics, leather and flexible plastics. However, the flexible rod can be locally reinforced by reinforcing portions of material relatively rigid.
  • the point portion of the shoe is preferably reinforced with a semi-rigid or rigid plastic part providing toe protection (not shown).
  • Soft rod should therefore be understood to mean a rod consisting mainly of flexible portions assembled together, without however, exclude the assembly of relatively more rigid portions.
  • the practice of skating requires designing a reinforcement structure which has the function of transmitting the pushing forces of the skater towards the ground, but also to ensure the protection and safety of the leg which take into account stresses experienced by it during practice.
  • This reinforcement structure is present in the form of a sub-assembly 6 which surrounds the sensitive areas of the foot.
  • the sub-assembly includes a heel counter 60 and a collar 61 connected on the sides of the buttress by articulation means 62.
  • the shoe comprises a rear sole portion 63 which is rigid enough so that it does not, or only slightly, deform during the movement of skating.
  • This portion is independent of the flexible rod 2 and is an integral part of the reinforcement subset 6.
  • ⁇ independent ⁇ it should be understood that the portion is considered to be structurally distinct from the flexible stem although it can be connected to it by permanent or detachable fixing means.
  • the rear sole portion 63 includes a front end 63a ending under the flexible rod, behind the tip of the shoe, and which is connected to the chassis by a hinge 7.
  • the joint is located in the metatarsal region or slightly behind the metatarsal region. According to the invention, it has been determined that it is in this region that we get the best power output.
  • the articulation corresponds, from preferably a simple axis of rotation.
  • the rigid sole portion 63 can be integral with the heel counter or, in an alternative, be made up of a independent part connected by connecting means such as by gluing, screws or rivets, or a combination of these.
  • the front portion 20 of the flexible rod comprises, for its part, a portion of sole 22 which is fixedly connected to the chassis 4.
  • the front sole portion 22 is fixed by fastening means 23 located in the toe region.
  • the part of the sole is extended towards the rear by a rear portion 24 which rests on the rigid rear sole portion 63 of the reinforcement sub-assembly.
  • the sole of the rod is fixed to the frame only in the front region of the foot; that is to say, in front of the joint 7. In this way, the flexible rod is forced to bend during the heel lift of the shoe. The bending is exerted appreciably in the plane vertical passing through the joint. It is therefore advantageous to provide that the shoe have sufficient flexibility at least in this area.
  • the rod should actually be both resistant to repeated bending movements in this area and sufficiently flexible so as not to hinder the free bending of the shoe. It should also be noted that the heel of the flexible upper moves in the rigid heel counter 60 by a few millimeters during bending of the rod. To encourage this movement, it is expected that the portion of rear sole 24 of the flexible upper is free relative to the sole portion rigid 63.
  • the rod can be coupled to the reinforcement sub-assembly 6 by means such as a strap 64 or additional connecting means (not shown) promoting the entrainment of the rod in bending so as to avoid detachment of the heel from the upper relative to the base.
  • Figure 2 shows the shoe during a resting configuration on the chassis or corresponding to a sliding or rolling phase.
  • the sole portion rear 63 of the reinforcement sub-assembly 6 has a lower surface 63b support which rests on the support base 40 of the chassis.
  • the base 40 corresponds to a transverse surface, preferably substantially planar, connecting the sides of the chassis supporting the wheels. This base 40 can extend continuously over any the length of the chassis or, on the contrary, only extend over part of its length.
  • the portion of sole 63 extends laterally and downwards by two guide walls 63c, 63d ( Figure 4). These two walls are spaced transversely from one another by distance substantially greater than the width of the chassis 4. These walls serve to ensure better guidance of the rear part of the shoe in the plane longitudinal hinge P of the shoe relative to the chassis and allows reduce the risk of twisting around the joint.
  • an elastic return element 8 equips, preferably, the pad to favor the return to the rest position or heel support of the shoe on the chassis. This reminder opposes a resistance couple elastic which tends to bring the lower bearing surface 63b closer to the portion of rigid sole 63, on the support base 40 of the chassis when the heel is raised.
  • the force of the return element must be sufficient to allow this approximation in the absence of a voluntary extension effort on the part of the skater; so that the undercarriage returns to rest position automatically after pushing, without that the skater does not have to worry about the position of the running gear in relation to his shoe.
  • Such elastic return means 8 is preferably a bending plate elastic housed in the shoe. As shown in Figure 3, the plate is located covering the rigid rear portion 63 on which it rests and the front portion 20 of rod so as to deform in bending during a lifting of the rear portion relative to the articulation point 7.
  • the plate can be accommodated discreetly under an insole, for example. It is therefore an element simple, reliable and economical to implement. Of course, other means elastic bands performing an equivalent return function can be envisaged without going beyond the scope of the invention. So we can consider replacing the bending plate by torsion springs mounted on the hinge pin 7.
  • FIG. 4 illustrates the arrangement of the rod relative to the subset of reinforcement in the rear part of the shoe.
  • the flexible rod portion is inserted in the heel buttress 60 of the reinforcement sub-assembly 6.
  • a connection between the flexible portion 24 internal and the rigid sole portion 63 external is not desirable so as to allow relative sliding of the flexible rod relative to the reinforcing structure in the sole region when flexing.
  • a connection 61a between the rod and the reinforcement structure is necessary, for example, at the level of the collar 61, to keep the rod integral with the sub-assembly reinforcement.
  • FIG. 5 relates to a variant of the invention in which the portion of rigid rear sole 63 is an independent element of the reinforcement structure and is in the form of a plate on which the rod 2 rests.
  • the portion rear of the sole of the upper is preferably linked to the plate 63 by means of sliding type link allowing relative longitudinal movement front / rear when bending the rod.
  • Such means may include sleeves 63e, 63f, connected on the sole of the flexible rod and in which the plate 63.
  • sleeves can be distributed longitudinally on the plate as required. Their function is to keep the rod and the plate 63 integral during rotation while promoting relative longitudinal guidance of the rod by compared to the plate.
  • the reinforcing structure 6 is located in part at least inside the flexible rod as shown by the dotted lines.
  • This structure can be formed a heel counter 60 and a support element 61 surrounding at least partially the ankle.
  • the heel counter and the support element can be formed in one piece by molding a rigid plastic.
  • Figure 6 shows a detailed view of a variant of the invention in which there are possibilities of adjusting the longitudinal position of the shoe relative to the chassis in different configurations.
  • the front portion 20 of the shoe comprises a fastening means 23 intended to cooperate selectively with a series of positions for receiving the fastening means spaced apart longitudinally from one another on the chassis.
  • the fixing means can be a screw 23a / nut 23b assembly.
  • the screw 23a passes through the front sole portion 22 of the shoe.
  • a series of holes 41a, 41b, 41c, are arranged in the base 40 of the chassis in a longitudinally spaced manner by a predetermined pitch p 1 .
  • Each hole corresponds to a selected position of the front portion 20 of the shoe as soon as the screw / nut assembly cooperates with one of the holes.
  • a single fixing means 23 has been shown, but of course, it is possible to envisage several fixing means spaced transversely and / or longitudinally from one another.
  • a second adjustment configuration can be proposed to move the articulation point 7 longitudinally relative to the chassis 4.
  • the position of the articulation has a very significant effect on the efficiency of the thrust exerted by the skater.
  • the adjustment adjusts the position of the joint relative to the relative position of the metatarsals according to the morphology of each skater.
  • the adjustment is obtained, for example, by providing a series of transverse bearings 42a, 42b, 42c in the chassis intended for the reception of the articulation axis of the rigid sole portion 63.
  • the bearing axes are spaced from a predetermined step p 2 .
  • the step p 1 can be equal to the step p 2 ; which allows relative movement of the entire shoe relative to the chassis.
  • p 1 and p 2 can have separate values. In general, one can consider one or other of the settings, or both in combination.
