Definitions

• the subject of the present invention is a system for attaching a shoe to a sporting article, in particular a gliding sport such as cross-country skiing, touring ski (touring), telemark, ice skating or skating. on casters.
• a gliding sport such as cross-country skiing, touring ski (touring), telemark, ice skating or skating. on casters.
• the boot In traditional type fastening systems used in cross-country skiing, the boot is attached to the sporting article generally in front of it by means of a hinge-type connection allowing movement of the shoe compared to the sports article, that is to say a heel lift.
• the shoes of such a system generally have a transverse axis placed at the front end of the sole which can hinder when walking.
• this elastic element is subject to significant fatigue and rapid wear due to repeated flexions of the foot during the practice of sport, so that the characteristics of rigidity and elastic return mentioned above evolve over time.
• the object of the present invention is to remedy these drawbacks and to propose an improved fastening device, reconciling the problems of lifting the heel of the shoe, controlling torsion and fatigue of the materials.
• the device for fixing the system according to the invention which is of the type comprising front stop means cooperating with the front end of the shoe and elastic fastening means cooperating with associated sole fastening means disposed behind the front end of the sole and exerting on said sole a tensile force in the direction of said abutment means, thereby that the elastic hooking means are anchored on the fixing device, behind the front stop means.
• the anchoring means of the elastic hooking means can be moved in the longitudinal direction against elastic means.
• the anchoring of elastic attachment means is constituted by a hinge, which makes it possible to be completely exempt from any energy linked to bending.
• FIG. 1 is a perspective view of a fixing device according to the invention during operation
• FIG. 2 is a view in partial longitudinal section of the fastening device of FIG. 1 in the boot position
• FIG. 3 is a view similar to FIG. 2 in the closed position, in the resting state of the boot,
• FIG. 4 is a view similar to FIG. 3 in the raised state of the shoe
• FIG. 5 is a partial sectional view of the lower part of the shoe
• FIG. 6 is a schematic view of another embodiment during closure of the fixing device.
• FIG. 1 shows the application of the connection system according to the invention to the connection to a ski 1 of a cross-country ski boot 10, this connection being effected by means of a fastening device 20 and d 'a guide rib 70.
• the shoe 10 has a sole 11, provided at the front end with a wide peripheral rim 12 defining, at its junction with the upper of the shoe, a groove 13, and comprising over the entire length from its underside a median longitudinal groove 14.
• the sole 11 rises in roundness with a slight curvature 11a in the manner of the shoes of classic mountains. The curvature 11a is intended to facilitate the unwinding of the shoe as will be seen below.
• An insert 15 is also fixed, for example by screws 16 or even by overmolding, at the bottom of the groove 14, in an area corresponding substantially to the metatarsophalangeal articulation area.
• This insert 15 defines a hook 17 oriented towards the rear.
• the fixing device 20 consists of a base 21 fixed to the ski 1 by screws 22 and on which a locking lever 30 is articulated, by means of an axis 31.
• the locking lever 30 is also connected to the base 21 by two lateral links 32, articulated, on the one hand, at 33 on said lever 30, and on the other hand, by a transverse axis 34 sliding in lateral openings 23 of the base.
• the lever 30-link 32 assembly forms a toggle joint system, the neutral line of which is defined by the axes 31 and 34.
• a slide 35 substantially in the form of a yoke and comprising two longitudinal walls 36 and a bottom wall 37. This slide 35 receives a compression spring 38.
• the spring 38 is held between the bottom 37 of the slide, which has a projection 37a intended for this purpose, and the front end 41 of a carriage 40.
• the carriage 40 is slidably mounted in the base 20 which comprises for this purpose a guide slide 25 opening laterally on the sides of the base 20.
• On the rear end 42 of the carriage 40 is articulated an elastic hooking wire 50 intended to cooperate with the hook 17 of the shoe.
• the elastic hooking wire 50 has substantially the shape of a U and comprises a transverse branch 52 intended to cooperate with the hook 17 and two lateral branches 51 whose curved ends 53 are articulated on the carriage 40.
• the fastening device also comprises front stop means constituted in this case by a stirrup 60 comprising a horizontal branch 61 in the form of an arc of a circle matching the shape of the groove 13 of the sole of the shoe and intended to receive this last and two lateral branches 62, substantially vertical and articulated by their ends 63, on the base 20.
• the stirrup 60 is disposed 4
• stirrup does not cooperate with a groove 13 in the sole but simply with the upper surface of the peripheral rim 12.
• the fastening device comprises a guide rib 70 whose cross section corresponds to that of the groove 14 of the shoe and whose front end 71 adjusts to the rear part of the base 20 which also forms a rib guide.
• the operation of the fixing system according to the invention is as follows.
• the shoe 10 is put into place in the fastening device by introducing the front end of its sole into the stirrup 60 until the groove 13 abuts with the horizontal branch 61 of the stirrup (cf. figure 2).
• the boot During skiing, the boot, the heel of which remains free, can bend, dragging in its course the fastening wire 50 which both slides in the base 20 towards the rear while compressing the spring 38 via of the carriage 40 and pivots upwards around its ends 53 (cf. FIG. 4).
• the spring 38 then supplies the energy for returning the boot to the upper surface of the ski since it tends to relax and therefore to bring the fastening wire 50 forward.
• the return energy is therefore not provided by an elastic deformation of the wire 50 which therefore ages much better.
• this return energy is completely defined since it is given by the compression of a compression spring 38 and is better controlled and controllable than if it were provided by the bending of a wire as in the prior art.
• the movement, rearwardly relative to the front stop means 60, of the anchor 53 of the spring wire provides a triangulation allowing better retention of the shoe in particular in transverse direction.
• the guide rib 70 is interrupted in the metatarsal area for the passage of the attachment wire 50 and the associated hook of the shoe.
• the shapes of the guide edge are also designed to optimize the guidance of the shoe.
• FIG. 6 schematically illustrates a second embodiment in which similar or identical elements are designated by the same references increased by 100.
• this fixing system includes the same locking elements, namely front stop stirrup 160 articulated in 163, hooking wire 150 connected to a carriage 140, which is slidably mounted, is biased forward by a spring. 138 and whose movement in the longitudinal direction is controlled by a lever 130.
