Definitions

  • the present invention relates to a toe clip for windsurfing or similar sporting device sliding or rolling on a support medium, for which the user, who acts on the position of an orientable mast by means of 'a boom or a wishbone attached to the sail, has its feet which rest on the board or a profiled support, moving on its support medium while being propelled by the effect of the wind acting on the sail.
  • the present invention relates to a safety device which avoids these drawbacks, by making it possible, in the event of an abrupt twisting or bending of the feet or of the leg of a user, in particular during a fall thereof, to instantly release the toe clips in which the user has normally engaged each of his feet.
  • the safety device according to the invention in which the toe clip comprises a strap fixed at one end to the board is characterized in that the other end on the strap 8 is secured to a bolt 20 capable of be engaged in a locking body 10 with a first elasticity in a first determined direction and then to be locked in said locking body 10 with a second elasticity in a second direction perpendicular to the first determined direction, so that under the effect of '' a pulling force of the bolt in the second direction, the bolt unlocks while remaining engaged in the locking body and only under the effect of a shearing force of the bolt in the first direction, the bolt is released from the locking body and opens the hoop.
  • the first elasticity is achieved by means of the bolt which is made up of two parallel branches rigidly connected on one side and elastically on the other.
  • the elastic mounting of the parallel branches makes it possible, on the one hand, to engage the bolt in the locking body but, on the other hand, to disengage it from said locking body in the case of a shearing force which tends to reduce the opening of said branches.
  • the engagement of the bolt on the locking body is carried out by means of lugs carried by the ends of the parallel branches on the elastic side.
  • the second elasticity is obtained in the locking body by a sliding element, one end of which cooperates with a spring working in compression, and the other end of which has a bearing face which cooperates with a corresponding bearing face of the pin. so as to lock said bolt on the locking body.
  • a determined tearing force on the arch of the toe clip causes the sliding element and the escape of the bolt to move relative to the locking body by sliding from one bearing face to the other. .
  • the compression of the spring is adjustable by a wheel, fixed in translation, which cooperates with a threaded axis, fixed in rotation, one end of said axis cooperating with said spring, so that the rotation of the wheel more or less compresses the spring, this which makes it more or less difficult to lock and unlock the targette.
  • a windsurf board 1 comprises, in a well-known manner, an adjustable mast 2, fixed in the axis of the latter by means of a nozzle 3, allowing a user 4 to tilt the mast vertically as well as forwards or backwards as necessary, to ensure the evolutions and in particular the catch in the wind of the craft.
  • the user 4 holds in his hands a boom or a wishbone 5, fixed to the mast 2 and making it possible to tension and orient a sail 6, all these provisions being perfectly conventional in the technique of using a such a board.
  • the user engages his feet inside toe clips 7, fixed on the top of the board 1 with an appropriate orientation, so as to ensure him on the board a fixed support, allowing it to laterally shift the weight of its body to balance the wind hold of the sail 6 and cause the board to propel. In the event of a fall, it can therefore be seen that the user risks twisting or bending his feet or his legs in a direction which could, if necessary, lead to an accident.
  • FIGS 2, 3, 4 and 5 illustrate on a larger scale the detail of the realization of a toe clip 7 according to the invention, the latter being provided with a safety device allowing, in normal operation, d '' maintain the immobilized foot of the user engaged in it but, in the event of a torsional force or sudden bending beyond a predetermined threshold, in particular during a fall, to release this foot without risk a sprain or even a fracture.
  • the clip 7 essentially consists of a strap 8, non-elastic, consisting of a braid or a flat ribbon, fixed at one end to a loop 9 secured to the upper face of the board 1 and at the other end on a locking body 10, this strap thus forming between the loop and the lock a kind of arch delimiting with the board a space 11 where the user engages his foot in a manner previously explained .
  • the strap 8 is actually formed of two strands respectively 12 and 13, secured to each other after passing through the loop 9, itself immobilized on the board 1 by construction.
  • This loop can thus include a housing 14, laterally provided with two holes for mounting fixing screws and comprising a transverse slot 16 and a central bar 17.
  • the strand 12 of the strap after passing through the slot 16 on one side of the bar 17 passes under it then is extended by the strand 13 which emerges from the housing 14 through the same slot 16 but on the opposite side of the bar, thereby immobilizing the strap.
  • the strands 12 and 13 are advantageously secured to each other for the major part beyond the housing 14 by sewing or the like, and are advantageously covered with a coating 18 made of plastic foam or of another material of the same kind, allowing in the closed position of the toe clip 7, to apply the strap against the user's foot without risking injury to the user.
  • This bolt 20 has the general shape of the letter U which includes a base 22 and two lateral branches 23 and 24. In addition to the base 22, these two lateral branches 23 and 24 are connected by the pin 21 for holding the strap and by a spacer 25 disposed at the opening end of the U opposite the base 22.
  • the branches 23 and 24 and the spacer 25 have a certain elasticity so as to allow the ends of the branches to move in a direction parallel to the base 22.
  • the ends of the branches of the U carry pins or pins 26 and 27 which project outwards from the U, perpendicular to the branches 22 and 23 and parallel to the base 22.
  • All of the elements of the bolt 20, with the exception of the axis 21, are, for example, made of plastic material at an appropriate thickness to obtain good mechanical resistance to the forces coming from the strap by means of the axis 21 while allowing a displacement of the ends of the lateral branches 23 and 24 at the pins 26 and 27.
  • the spacer 25 has the shape of the letter V whose tip 28 is disposed inside the branches 23 and 24 while the points 29 and 30 are integral with the ends of said branches.
  • the axis 21 is, for example, made in the form of a stainless steel rod which is held in two bores drilled in the branches 23 and 24. One end of the rod or axis 21 is terminated by a head while the the other is threaded so as to cooperate by screwing with one of the two bores which is tapped.
  • the head of the rod is, for example, a countersunk screw head, which allows the rod 21 to be screwed into the tapped bore using a screwdriver.
  • the lower 22 is shaped to produce a bearing face having a boss 66 whose role will be explained below.
  • the latter comprises a sole 34 of rectangular shape whose long sides are flanked by cheeks or flanges 35 and 36 having a height greater than the thickness of the sole 34.
  • These cheeks are each pierced, at one end, with an orifice 37 and 38 in which the pins 26 and 27 of the bolt snap in so as to allow the latter to rotate around the axis produced by the pins 26 and 27.
  • the sole 34 has orifices such as that referenced 39, to allow it to be fixed to the windsurf board by a screw as referenced 40.
  • the sole 34 serves as a support for an actual locking device for the bolt 20.
  • This device comprises a heel 41 disposed on the side of the orifices 37 and 38 and integral with the sole.
  • This heel 41 extends over a certain length of the sole and has two cavities 52 and 53.
  • the cavity 52 serves as a housing for an axis 42, fixed in rotation associated with a wheel 43 fixed in translation.
  • One end 44 of the axis 42 is square and is supported by a notch of square section 46 serving as blocking of the axis while the other end is supported by a cylindrical bore 45 serving as a bearing.
  • This axis 42 has a thread which cooperates with the threaded orifice of the wheel 43.
  • This wheel 43 can therefore rotate around the axis 42 by the effect of the threads indicated above, and its rotation is obtained by the fact that its outer peripheral periphery is accessible outside of the heel 41 via an opening 47 formed on the side opposite the sole.
  • this sole is provided with a housing 48 for the periphery of the wheel 43.
  • This wheel / axis arrangement makes it possible to move the axis 42 longitudinally in one direction or another as indicated by the double arrow 49.
  • a cap 71 For mounting the axle 42 in the wheel 43, provision is made to make an opening on the rear of the heel 41 and to close it with a cap 71.
  • the cap 71 is fixed to the heel 41 using 'a screw 72.
  • the cavity 53 serves as a housing for a spring 50 which cooperates, on the one hand, on one side with the axis 42 and, on the other hand, on the other side with a plate 51 having a particular cut and shape .
  • This plate 51 of substantially rectangular shape, is cut, on one side, that of the heel 41, to present three legs, a central leg 54 and two lateral legs 55 and 56.
  • the central leg enters the housing 43 through a slot 57 of the heel 41 and its end cooperates with the spring 50.
  • the notches 58 and 59 between the central leg 54 and the legs lateral 55 and 56 correspond to the thickness of the lateral walls of the heel 41, which allows displacements of the plate 51 in the directions materialized by the double arrow 49.
  • the ends of the lateral tabs 55 and 56 are bent downwards in direction of the sole and these curved ends 60 and 61 are housed in notches in the sole such as that referenced 62.
  • the end 62 of the plate 51 opposite to that carrying the legs 54, 55 and 56 is bent upwards and this curved end 62 has a suitable shape, in particular a recess 73, for cooperating with the base 22 (boss 66) of the bolt 20 so as to snap the bolt onto the end 62 and lock the bolt the latter in the closed position.
  • the plate 51 is held in place against the sole 34 by bosses 63 and 64 carried by the cheeks 35 and 36, these bosses have a groove for the sliding of the plate 51.
  • the sliding length is limited by the length of the notches 62 provided for the curved ends 60 and 61 of the legs 55 and 56. This length of the notches is markedly shorter than that shown in FIG. 5 in order to allow adjustment of the hardness of the snap-fastening and therefore of the unlocking of the bolt.
  • the plate 51 has a central opening to allow access to the head of the fixing screw 40.
  • the hardness of this locking can be adjusted by rotating the wheel 43 in one direction or another in accordance with the indications + and - carried on the heel 41 near the wheel. Of course, this hardness can also be adjusted before the bolt clicks into place.
  • the user can then use the windsurf board.
  • a force is exerted on the axis 21 of the bolt in the direction of opening. If the component of this force along the axis of the spring 50 is greater than the locking force of the latter, the plate 51 moves towards the heel by compressing the spring, which releases the boss 66 and with it the bolt 20. As a result, the arch of the toe clip is no longer tensioned, which allows the release of the foot.
  • the exemplary embodiment of the safety device for a windsurfing toe clip which has just been described in relation to FIGS. 2 to 5 does not include means for adjusting the length of the arch to adapt it to the dimensions feet of various windsurfers. This adjustment can be carried out in different ways and one of them will now be described in relation to FIG. 6.
  • the strap 8, on the targette side is provided on either side with a band called "Velcro" 67 and 68 while the strands 12 and 13 of the part attached to the loop 9 are, on a certain length, not sewn together so as to allow their spacing, and their facing faces are also provided with a band called “Velcro” 69 and 70.
  • a band called "Velcro” 69 and 70 By pressing the strands 12 and 13 against the strap 8, the arch is produced the length of which can be varied at will by the relative position of the strands 12 and 13 and of the strap 8. It is clear that such an assembly by so-called “Velcro” strips must have a resistance to the opening of the hoop greater than that obtained with the safety device according to the invention.
