Abstract

A safety stirrup detachably connected to the stirrup-leather in order to release the rider's foot in the event of a fall comprises a coupling device having two jaws for clamping the top portion of the stirrup head. A forward pivotal displacement of the stirrup with respect to the stirrup-leather causes rotation of a cam provided at the upper end of the stirrup head. The two jaws are opened-out by a top wedge of the cam through an angle of approximately 30 DEG to 45 DEG while a bottom wedge of the cam increases the separation of the jaws, thus releasing the stirrup.

Description

La présente invention a pour objet un étrier de sécurité destiné à l'équitation, c'est-à-dire un étrier susceptible de se détacher l'étrivière correspondante pour assurer la libération du pied du cavalier en cas de chute de celui-ci. En effet, avec des étriers de type classique le pied risque alors de se trouver coinçé dans l'étrier correspondant ce qui risque d'entraîner un grave accident pour le cavalier.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. In fact, with stirrups of the conventional type, the foot then risks being trapped in the corresponding stirrup, which risks causing a serious accident for the rider.

Il a déjà été proposé différents systèmes de sécurité destinés à assurer la libération des pieds d'un cavalier lors d'une chute. Cependant les systèmes existant actuellement ne permettent pas de résoudre ce problème de façon pleinement satisfaisante.Various safety systems have already been proposed for ensuring the release of a rider's feet during a fall. However, the systems currently in existence do not make it possible to solve this problem in a fully satisfactory manner.

Ainsi, le brevet FR 403.632 décrit un étrier dont la tête est attachée à l'étrivière correspondante par l'intermédiaire d'un support susceptible de permettre la libération de cet étrier dans certaines circonstances. Ce support affecte la forme d'un arceau dont les branches sont disposées dans des plans s'étendant à angle droit par rapport au plan général de l'étrier. A leur extrémité inférieure, les deux branches de cet arceau comportent une saillie engagée dans une cavité ménagée sur le côté correspondant d'une protubérance prévue sur le dessus de la tête de cet étrier. La libération de l'étrier suppose donc que la chute du cavalier provoque une rotation de la protubérance de la tête de l'étrier entre les deux branches du support en forme d'arceau, de façon que les saillies de celles-ci se trouvent dégagées en dehors des cavités de cette protubérance. Toutefois, comme les deux branches du support en forme d'arceau sont disposées dans des plans s'étendant à angle droit par rapport au plan général de l'étrier, il se produit plutôt une rotation du support de l'étrier à l'intérieur de la boucle formée par l'étrivière, ou bien encore un vrillage de cette étrivière. Or, dans un cas comme dans l'autre, il n'y a pas libération de la tête de l'étrier par rapport à son support, puisqu'une telle libération nécessite obligatoirement une rotation de la protubérance supérieure de la tête de l'étrier entre les deux branches de son support.Thus, 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. However, since the two branches of the arch-shaped support are arranged in planes extending at right angles to the general plane of the stirrup, there is rather a rotation of the stirrup support inside of the loop formed by the stirrup, or even a twist of this stirrup. However, in one case as in the other, there is no release of the head of the stirrup relative to its support, since such release necessarily requires a rotation of the upper protuberance of the head of the bracket between the two branches of its support.

Quant au brevet GB 753 418, il décrit un système d'étrier de sécurité dans lequel la tête de l'étrier est attachée à l'étrivière correspondante par l'intermédiaire d'un dispositif d'accouplement comportant une lame élastique maintenant la tête de l'étrier en appui sur une patte de retenue engagée dans l'oeil de cette tête, tout en permettant son dégagement en cas d'effort anormal de pivotement de l'étrier. Là encore cette solution est imparfaite car il existe un jeu important de débattement de la tête de l'étrier sur-la patte de retenue et ce jeu facilite un dégagement intempestif de l'étrier par rapport à son dispositif d'accouplement. Par ailleurs, le système ainsi prévu ne permet pas de réaliser la libération de l'étrier dans des conditions précises de dégagement pour un effort déterminé de torsion. D'autre part, ce système ne présente pas une robustesse suffisante car la lame élastique assurant la retenue en place de l'étrier est très rapidement détériorée.As for 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. Again 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. Furthermore, the system thus provided does not allow the release of the stirrup under precise release conditions for a determined torsional force. On the other hand, this system does not have sufficient robustness because the elastic blade ensuring the retention in place of the stirrup is very quickly damaged.

C'est pourquoi la présente invention a pour but de réaliser un étrier permettant d'obtenir une sécurité optimum de libération du pied en cas de chute du cavalier et ce pour un effort déterminé de torsion, ce dispositif étant également conçu de manière à être extrêmement robuste.This is why 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.

A cet effet, l'invention a pour objet un étrier de sécurité pour l'équitation dont la tête est attachée à l'étrivière correspondante par l'intermédiaire d'une pince élastique dont les deux mâchoires enserrent la partie supérieure de la tête de cet étrier en ayant des éléments de retenue engagés dans un oeil de cette tête, caractérisé en ce que la partie supérieure de la tête de cet étrier affecte la forme d'une came comportant deux faces planes parallèles au plan général de l'étrier et contre lesquelles s'applique normalement les deux mâchoires de la pince d'accouplement, la forme de cette came permettant à celle-ci de provoquer un début d'écartement de ces deux mâchoires en cas de rotation de cette came sur elle-même, et en ce que la mâchoire de la pince d'accouplement, qui est destinée à être placée vers l'arrière, se prolonge vers le bas par une patte disposée en regard de la partie inférieure de la tête de l'étrier, pour constituer une butée s'opposant au pivotement de l'étrier vers l'arrière.To this end, 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.

Ainsi, la libération du pied ne peut se produire qu'en cas de pivotement relatif de l'étrier vers l'avant par rapport à l'étrivière correspondante, donc en cas d'un effort anormal dû à la chute du cavalier.Thus, 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.

Cependant, d'autres particularités et avantages de l'étrier de sécurité selon l'invention apparaîtront au cours de la description suivante de quelques exemples de réalisation de celui-ci. Cette description est donnée en référence au dessin annexé à simple titre indicatif, et sur lequel:

  • Les figures 7 et 8 sont des vues partielles en coupe similaires à la figure 2, mais qui représentent diverses autres formes de réalisation de l'étrier de sécurité selon l'invention.
However, other particularities and advantages of the safety stirrup according to the invention will appear during the following description of a few embodiments of it. This description is given with reference to the attached drawing for information only, and in which:
  • Figure 1 is a front elevational view of a first embodiment of the safety stirrup according to the invention and its coupling device with the corresponding stirrup;
  • Figure 2 is a vertical sectional view along line II-II of Figure 1, but on a different scale;
  • Figures 3 and 4 are similar views illustrating two successive phases of the release of the stirrup in the event of the rider falling;
  • Figure 5 is an elevational view of a saddle carrying the present stirrup, this view illustrating the operating conditions of the assembly;
  • Figure 6 is a partial view similar to Figure 2 which illustrates the mode of re-engagement of the caliper head between the two retaining jaws.
  • Figures 7 and 8 are partial sectional views similar to Figure 2, but showing various other embodiments of the safety stirrup according to the invention.

Les figures 1 à 6 représentent un exemple de réalisation dans lequel l'étrier correspondant 1 est attaché à l'étrivière 2 par l'intermédiaire d'un dispositif d'accouplement désigné par la référence générale 3. Celui-ci est constitué par une pince élastique dont les deux mâchoires 4 et 5 sont disposées dans deux plans sensiblement parallèles au plan général X-Y de l'étrier. Ces deux mâchoires emprisonnent entre elles la partie supérieure 6 de la tête 7 de l'étrier, c'est-à-dire la partie de cette tête qui se trouve située au-dessus de l'oeil 8 de celle-ci.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.

A leur extrémité inférieure, ces deux mâchoires portent, sur leur face en regard, des becquets 9 qui sont engagés à l'intérieur de l'oeil 8 de la tête de l'étrier. Ainsi, ces becquets servent d'éléments de retenue pour la partie supérieure 6 de cette tête.At their lower end, these two jaws carry, on their opposite face, spoilers 9 which are engaged inside the eye 8 of the head of the stirrup. Thus, these spoilers serve as retaining elements for the upper part 6 of this head.

Les deux mâchoires 4 et 5 sont portées par deux lames élastiques 10 dont les extrémités supérieures sont solidarisées l'une avec l'autre, par exemple par des points de soudure 11 ou des rivets. De plus, les extrémités supérieures de ces deux lames présentent une ouverture 12 à l'intérieur de laquelle est engagée l'étrivière 2 correspondante. Ainsi, les deux lames élastiques 10 constituent des moyens élastiques tendant à maintenir l'une vers l'autre les deux mâchoires 4 et 5 afin d'assurer l'accouplement de l'étrier 1 avec l'étrivière 2.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. In addition, the upper ends of these two blades have an opening 12 inside which is engaged the corresponding stirrup 2. Thus, 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.

La partie supérieure 6 de la tête de cet étrier est constituée par une came dont le profil est tel que celle-ci est apte à provoquer un début d'écartement des deux mâchoires de retenue 4 et 5 en cas de rotation de cette came sur elle-même jusqu'à un angle de l'ordre de 30 à 45° environ. De plus, cette came présente, à sa partie inférieure, un coin 13 qui est destiné à s'engager entre les becquets 9 des deux mâchoires de retenue après une telle rotation de la came 6 afin d'accroître l'écartement de ces mâchoires pour permettre l'échappement de la tête de l'étrier.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. In addition, 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.

A cet effet, abstraction faite d'une nervure supérieure 14 dont le rôle sera expliqué par la suite, la came 6 possède une section transversale de forme carrée ou rectangulaire. Ainsi, elle comporte une face inférieure 15, plane et horizontale, qui lui sert de surface d'appui sur les deux becquets 9 de retenue des deux mâchoires 4 et 5. Cependant, elle comporte également deux faces 16 perpendiculaires à cette surface d'appui et qui s'étendent dans des plans parallèles au plan général X-Y de l'étrier. Or, les deux mâchoires 4 et 5 s'appliquent normalement contre ces deux faces planes, ce qui assure le maintien ferme de l'étrier dans la position représentée à la figure 2, et ce sans aucune possibilité de jeu par rapport à son dispositif d'accouplement avec l'étrivière correspondante.For this purpose, apart from an upper rib 14 whose role will be explained later, the cam 6 has a cross section of square or rectangular shape. Thus, 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. However, 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. However, 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.

Comme il a déjà été indiqué, la came 6 ainsi constituée porte sur le dessus une nervure 14. Celle-ci présente une section transversale de forme triangulaire dont l'arête est dirigée vers le haut. Cette nervure est en effet destinée à constituer en quelque sorte un coin permettant une remise en place facile de la came 6 entre les deux mâchoires de retenue 4 et 5. En combinaison avec ce coin, les faces inférieures des deux becquets de retenue 9 présentent des chanfreins 17 destinés à faciliter l'engagement de ce coin entre les deux becquets, afin de provoquer l'écartement momentané des deux mâchoires de retenue 4 et 5 lors du ré-enclenchement de la came 6 entre ces deux mâchoires (voir figure 6).As already indicated, 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. In combination with this corner, 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).

Selon une autre caractéristique importante, la mâchoire 5 de retenue, qui est destinée à être placée vers l'arrière, se prolonge vers le bas par une patte 18 disposée en regard de la partie inférieure 19 de la tête de l'étrier, c'est-à-dire sa partie située au dessous de son oeil 8. De préférence, cette patte est normalement engagée à l'intérieur d'un décrochement 20 ménagé dans cette partie inférieure 19. Ainsi, cette patte constitue une butée s'opposant à toute possibilité de pivotement de l'étrier vers l'arrière par rapport à son dispositif d'accouplement 3.According to another important characteristic, 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. Preferably, this tab is normally engaged inside a recess 20 formed in this lower part 19. Thus, this tab constitutes a stop opposing any possibility of pivoting of the stirrup towards the rear relative to its coupling device 3.

En conséquence, il ne peut se produire, entre l'étrier et son dispositif d'accouplement, qu'un mouvement relatif de pivotement de l'étrier vers l'avant comme représenté sur la figure 3. Plus exactement, lors d'une chute du cavalier vers l'arrière, il se produit un mouvement relatif de pivotement de l'étrier 1 vers l'avant selon la flèche F1, alors que l'étrivière et le dispositif d'accouplement 3, porté par celle-ci, se trouvent relevés vers l'arrière.Consequently, there can only occur, between the stirrup and its coupling device, a relative pivoting movement of the stirrup forwards as shown in FIG. 3. More precisely, during a fall from the rider to the rear, there is a relative pivoting movement of the stirrup 1 forwards according to arrow F1, while the stirrup stirrup and the coupling device 3, carried by the latter, are located raised backwards.

Ainsi, la came 6 est amenée à tourner sur ellemê- me entre les deux mâchoires 4 et 5 jusqu'à un angle de rotation de l'ordre de 30 à 45°. Ceci provoque donc un début d'écartement des deux mâchoires 4 et 5 comme représenté sur la figure 3. A l'issue de ce mouvement de rotation le coin inférieur 13 de la came 6, qui est situé vers l'arrière, se trouve disposé en regard de l'intervalle existant à ce moment entre les deux becquets de retenue 9 en raison du début de l'écartement des deux mâchoires 4 et 5. Du fait de l'effort de traction exercé par l'étrivière 2, le coin 13 s'engage entre les deux becquets 9 de retenue et provoque ainsi un accroissement plus accentué de l'écartement des deux mâchoires 4 et 5, ce qui permet en définitive l'échappement de la tête de l'étrier (voir figure 4).Thus, 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. At the end of this rotational movement, 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. Due to the tensile force exerted by the stirrup 2, 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).

Dans ces conditions, l'étrier est libéré dans des conditions susceptibles d'assurer le maximum de sécurité Cependant lors d'un parcours normal d'équitation, cet étrier est parfaitement maintenu sans aucun jeu dans son dispositif d'accouplement avec l'étrivière, et ce grâce au fait que les deux mâchoires de retenue 4 et 5 se trouvent appliquées élastiquement contre les faces planes 16 de la came 6 de la tête de l'étrier. Par ailleurs, en raison même de la conception du présent dispositif, tout effort anormal de torsion sur le pied, résultant d'un début de chute du cavalier en arrière, provoque automatiquement, et de façon absolument certaine, la rotation de la came 6 entre les deux mâchoires de retenue et par suite, le dégagement de la tête de l'étrier par rapport aux deux mâchoires de retenue. A ce sujet, il est essentiel que ces mâchoires soient disposées dans des plans parallèles au plan général X-Y de l'étrier et que la rotation de la came 6 provoque un début d'écartement de ces deux mâchoires, lequel est suivi d'un écartement plus accentué dû à l'engagement du coin inférieur 13 entre les deux becquets de retenue 9. Du reste, la figure 5 illustre les conditions pratiques de libération de l'étrier.Under these conditions, the stirrup is released under conditions capable of ensuring maximum safety. However, during a normal riding course, 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. Furthermore, by reason of the design of the present device, 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. On this subject, it is essential that these jaws are arranged in planes parallel to the general plane XY of the stirrup and that the rotation of the cam 6 causes a start of separation of these two jaws, which is followed by a separation more accentuated due to the engagement of the lower corner 13 between the two retaining spoilers 9. Furthermore, FIG. 5 illustrates the practical conditions for releasing the stirrup.

La figure 7 représente une autre forme de réalisation de l'étrier de sécurité selon l'invention. La différence essentielle de celle-ci par rapport à la précédente réside dans la nature des moyens élastiques assurant le maintien des deux mâchoire de retenue l'une vers l'autre.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.

En effet, dans cette forme de réalisation les deux mâchoires correspondantes 4a et 5a s'articulent, à leur extrémité supérieure, autour d'un axe commun 21 constitué par la branche inférieure d'un anneau 22 à l'intérieur duquel est engagée l'étrivière correspondante 2a. Le maintien des deux mâchoires 4a l'une vers l'autre est alors assuré par un ressort de torsion 23 disposé autour de l'axe 21. Mais, abstraction faite de cette différence, 1a structure générale du présent dispositif est la même qui précédemment. En conséquence, le fonctionnement est également le même.Indeed, in this embodiment 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.

La figure 8 représente une autre forme de réalisation encore qui se différencie des précédentes par la nature des moyens élastiques agissant sur les deux mâchoires de retenue. Dans ce cas, les deux mâchoires correspondantes 4a et 5b sont portées par deux pattes rigides 24 qui s'articulent autour d'un axe commun 25. Les moyens élastiques tendant à rappeler les deux mâchoires l'une contre l'autre, sont constituées par un ressort de pression 26 disposé autour d'une vis 27 portée par l'une des pattes 24 et qui traverse l'autre. Un écrou 28 vissé sur l'extrémité de cette vis permet alors de régler à volonté la pression élastique de rappel des deux mâchoires 4b et 5b.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. In this case, 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.

Mais là encore, abstraction faite de cette différence, l'agencement des deux mâchoires est le même que dans la première forme de réalisation. La came 6 portée par la tête de l'étrier est également identique à celle prévue dans cette première forme de réalisation. En conséquence, le fonctionnement est le même.But here again, apart from this difference, the arrangement of the two jaws is the same as in the first embodiment. The cam 6 carried by the head of the stirrup is also identical to that provided in this first embodiment. Consequently, the operation is the same.

Cependant, l'étrier de sécurité selon l'invention n'est pas limité aux quelques exemples qui ont été décrits ci-dessus, à simple titre indicatif. Ainsi, les moyens élastiques de rappel des deux mâchoires de retenue pourraient être autres que ceux envisagés précédemment. Eventuellement, ces moyens élastiques de rappel pourraient consister en un bloc ou tampon en caoutchouc, ou autre matière élastique appropriée.However, the safety stirrup according to the invention is not limited to the few examples which have been described above, for information only. Thus, the elastic return means of the two retaining jaws could be other than those envisaged previously. Optionally, these elastic return means could consist of a rubber block or pad, or other suitable elastic material.
