Definitions

  • the present invention relates to a safety stirrup intended for riding, that is to say a stirrup capable of detaching the corresponding stirrup to ensure the release of the rider's foot in the event of the latter falling.
  • a safety stirrup intended for riding that is to say a stirrup capable of detaching the corresponding stirrup to ensure the release of the rider's foot in the event of the latter falling.
  • stirrups of the conventional type the foot then risks being trapped in the corresponding stirrup, which risks causing a serious accident for the rider.
  • the patent FR 403.632 describes a stirrup whose head is attached to the corresponding stirrup by means of a support capable of allowing the release of this stirrup in certain circumstances.
  • This support takes the form of an arch, the branches of which are arranged in planes extending at right angles to the general plane of the stirrup. At their lower end, the two branches of this hoop have a projection engaged in a cavity formed on the corresponding side of a protuberance provided on the top of the head of this stirrup. The release of the stirrup therefore supposes that the fall of the rider causes a rotation of the protuberance of the head of the stirrup between the two branches of the arch-shaped support, so that the projections thereof are released outside the cavities of this protuberance.
  • GB 753 418 it describes a safety stirrup system in which the head of the stirrup is attached to the corresponding stirrup by means of a coupling device comprising an elastic blade holding the head of the stirrup resting on a retaining tab engaged in the eye of this head, while allowing its release in the event of an abnormal pivoting effort of the stirrup.
  • a coupling device comprising an elastic blade holding the head of the stirrup resting on a retaining tab engaged in the eye of this head, while allowing its release in the event of an abnormal pivoting effort of the stirrup.
  • this solution is imperfect because there is a large clearance of movement of the head of the caliper on the retaining tab and this game facilitates an untimely release of the caliper relative to its coupling device.
  • the system thus provided does not allow the release of the stirrup under precise release conditions for a determined torsional force.
  • this system does not have sufficient robustness because the elastic blade ensuring the retention in place of the stirrup is very quickly damaged
  • the aim of the present invention is to produce a stirrup making it possible to obtain optimum security for the release of the foot in the event of the rider falling and for a determined torsional force, this device also being designed so as to be extremely robust.
  • the subject of the invention is a safety stirrup for riding, the head of which is attached to the corresponding stirrup by means of an elastic clamp, the two jaws of which enclose the upper part of the head of this stirrup having retaining elements engaged in an eye of this head, characterized in that the upper part of the head of this stirrup assumes the shape of a cam having two plane faces parallel to the general plane of the stirrup and against which normally applies the two jaws of the coupling clamp, the shape of this cam allowing it to cause a start of separation of these two jaws in case of rotation of this cam on itself, and in this that the jaw of the coupling clamp, which is intended to be placed towards the rear, extends downwards by a tab arranged opposite the lower part of the head of the stirrup, to constitute a stop s' opposing the pivoting of the wormhole s rear.
  • the release of the foot can only occur in the event of relative pivoting of the stirrup forwards relative to the corresponding stirrup, therefore in the event of an abnormal force due to the fall of the rider.
  • Figures 1 to 6 show an embodiment in which the corresponding stirrup 1 is attached to the stirrup 2 by means of a coupling device designated by the general reference 3.
  • This consists of a clamp elastic, the two jaws 4 and 5 of which are arranged in two planes substantially parallel to the general plane XY of the stirrup. These two jaws trap between them the upper part 6 of the head 7 of the stirrup, that is to say the part of this head which is located above the eye 8 thereof.
  • these two jaws carry, on their opposite face, spoilers 9 which are engaged inside the eye 8 of the head of the stirrup.
  • spoilers 9 serve as retaining elements for the upper part 6 of this head.
  • the two jaws 4 and 5 are carried by two elastic blades 10, the upper ends of which are secured to one another, for example by welding points 11 or rivets.
  • the upper ends of these two blades have an opening 12 inside which is engaged the corresponding stirrup 2.
  • the two elastic blades 10 constitute elastic means tending to hold the two jaws 4 and 5 towards each other in order to couple the stirrup 1 with the stirrup 2.
  • the upper part 6 of the head of this stirrup is constituted by a cam whose profile is such that it is capable of causing the start of separation of the two retaining jaws 4 and 5 in the event of rotation of this cam on it - even up to an angle of about 30 to 45 ° approximately.
  • this cam has, at its lower part, a wedge 13 which is intended to engage between the spoilers 9 of the two retaining jaws after such rotation of the cam 6 in order to increase the spacing of these jaws for allow the caliper head to escape.
  • the cam 6 has a cross section of square or rectangular shape.
  • it has a lower face 15, flat and horizontal, which serves as a bearing surface on the two spoilers 9 for retaining the two jaws 4 and 5.
  • it also has two faces 16 perpendicular to this bearing surface and which extend in planes parallel to the general XY plane of the stirrup.
  • the two jaws 4 and 5 are normally applied against these two flat faces, which ensures that the stirrup is held firmly in the position shown in FIG. 2, and this without any possibility of play with respect to its device d 'coupling with the corresponding stirrup.
  • the cam 6 thus formed carries on the top a rib 14.
  • the latter has a cross section of triangular shape, the edge of which is directed upwards.
  • This rib is in fact intended to constitute in a way a corner allowing an easy repositioning of the cam 6 between the two retaining jaws 4 and 5.
  • the lower faces of the two retaining spoilers 9 have chamfers 17 intended to facilitate the engagement of this corner between the two spoilers, in order to cause the temporary separation of the two retaining jaws 4 and 5 during the re-engagement of the cam 6 between these two jaws (see FIG. 6).
  • the retaining jaw 5, which is intended to be placed towards the rear, is extended downwards by a lug 18 disposed facing the lower part 19 of the head of the stirrup, this that is to say its part located below its eye 8.
  • this tab is normally engaged inside a recess 20 formed in this lower part 19.
  • this tab constitutes a stop opposing any possibility of pivoting of the stirrup towards the rear relative to its coupling device 3.
  • the cam 6 is caused to rotate on itself between the two jaws 4 and 5 to an angle of rotation of the order of 30 to 45 ° .
  • This therefore causes the spacing of the two jaws 4 and 5 to begin as shown in FIG. 3.
  • the lower corner 13 of the cam 6, which is situated towards the rear is disposed opposite the gap existing at this time between the two retaining spoilers 9 due to the start of the spacing of the two jaws 4 and 5.
  • the wedge 13 engages between the two retaining spoilers 9 and thus causes a more accentuated increase in the spacing of the two jaws 4 and 5, which ultimately allows the escape of the caliper head (see FIG. 4).
  • stirrup is released under conditions capable of ensuring maximum safety.
  • this stirrup is perfectly maintained without any play in its coupling device with the stirrup, and this thanks to the fact that the two retaining jaws 4 and 5 are applied elastically against the flat faces 16 of the cam 6 of the head of the stirrup.
  • any abnormal torsional force on the foot resulting from the beginning of a fall of the rider backward, automatically causes, and absolutely absolutely, the rotation of the cam 6 between the two retaining jaws and consequently, the clearance of the caliper head relative to the two retaining jaws.
  • FIG. 5 illustrates the practical conditions for releasing the stirrup.
  • FIG. 7 shows another embodiment of the safety stirrup according to the invention.
  • the essential difference of this one compared to the previous one lies in the nature of the elastic means ensuring the maintenance of the two retaining jaws towards one another.
  • both corresponding jaws 4a and 5a are articulated, at their upper end, around a common axis 21 formed by the lower branch of a ring 22 inside which is engaged the corresponding stirrup 2a. Maintaining the two jaws 4a towards each other is then ensured by a torsion spring 23 disposed around the axis 21. But, apart from this difference, the general structure of the present device is the same as before. Consequently, the operation is also the same.
  • FIG. 8 represents yet another embodiment which differs from the previous ones by the nature of the elastic means acting on the two retaining jaws.
  • the two corresponding jaws 4a and 5b are carried by two rigid tabs 24 which are articulated around a common axis 25.
  • the elastic means tending to bias the two jaws against each other are constituted by a pressure spring 26 disposed around a screw 27 carried by one of the tabs 24 and which passes through the other.
  • a nut 28 screwed onto the end of this screw then makes it possible to adjust the elastic return pressure of the two jaws 4b and 5b as desired.
  • the safety stirrup according to the invention is not limited to the few examples which have been described above, for information only.
  • the elastic return means of the two retaining jaws could be other than those envisaged previously.
  • these elastic return means could consist of a rubber block or pad, or other suitable elastic material.
