Description

DESCRIPTION DESCRIPTION
Titre : Etrier de sécurité pour l'équitation Title: Safety stirrup for horse riding
La présente invention porte sur un étrier de sécurité pour l'équitation. The present invention relates to a safety stirrup for riding.
On connaît par la demande de brevet WO2021156736 un étrier de sécurité pour l’équitation, comprenant une structure de cadre munie d’une partie d’accrochage à une sangle d’étrier, un élément d’appui pour le pied de l’utilisateur, et un bras de sécurité. Cet étrier permet la libération immédiate du pied de l’utilisateur lorsque cela est nécessaire, par exemple lorsqu'un cavalier est projeté ou tombe de cheval. Patent application WO2021156736 discloses a safety stirrup for horse riding, comprising a frame structure provided with a part for attaching to a stirrup strap, a support element for the user's foot, and a safety arm. This stirrup allows the immediate release of the user's foot when necessary, for example when a rider is thrown or falls from a horse.
L'invention vise à proposer un étrier de sécurité d'un nouveau genre, qui apporte un certain nombre d'avantages comme on le verra ci-après. The invention aims to provide a safety stirrup of a new kind, which provides a number of advantages as will be seen below.
La présente invention a ainsi pour objet un étrier de sécurité comportant un corps pourvu d'un support d'appui pour un pied d'un cavalier, le corps étant en outre pourvu d'un cadre en forme d'arche, l'étrier comportant un dispositif de retenue du pied, ce dispositif de retenue étant monté pivotant sur le cadre entre une position fermée dans laquelle le dispositif de retenue est enclenché de sorte que ce dispositif de retenue soit solidarisé au cadre et une position ouverte dans laquelle le dispositif de retenue est déclenché de manière à être pivotable par rapport au cadre, autour d'un axe de pivotement, suivant un mouvement de pivotement limité à un seul côté du cadre, ce côté de pivotement étant le côté d'engagement du pied par lequel le pied du cavalier s'engage dans l'étrier, étrier dans lequel le dispositif de retenue est agencé pour se déclencher en cas de basculement du pied du cavalier, par exemple en cas de chute du cavalier, de sorte à libérer le pied du cavalier. The subject of the present invention is thus a safety stirrup comprising a body provided with a support support for a rider's foot, the body being further provided with an arch-shaped frame, the stirrup comprising a foot retaining device, this retaining device being pivotally mounted on the frame between a closed position in which the retaining device is engaged so that this retaining device is secured to the frame and an open position in which the retaining device is released so as to be pivotable with respect to the frame, around a pivot axis, following a pivoting movement limited to a single side of the frame, this pivoting side being the foot engagement side by which the foot of the rider engages in the stirrup, stirrup in which the retaining device is arranged to be triggered in the event of the rider's foot tipping over, for example in the event of the rider falling, so as to release the rider's foot.
Le dispositif de retenue selon l'invention, qui sert à empêcher que le pied du cavalier ne s'enfonce excessivement et dangereusement dans l'étrier, ne peut pivoter que du côté permettant de libérer le pied du cavalier. Ce dispositif de retenue est bloqué pour un mouvement de pivotement, notamment un pivotement d'une amplitude angulaire limité à 90°, de sorte que ce dispositif de retenue soit empêché de pivoter de l'autre côté du cadre. En cas de chute du cavalier, le basculement du pied du cavalier vient exercer sur le dispositif de retenue une force qui le fait passer de la position fermée à la position ouverte dans laquelle ce dispositif de retenue est déclenché, libérant le pied qui n'est plus retenu sur l'étrier. The retaining device according to the invention, which serves to prevent the rider's foot from sinking excessively and dangerously into the stirrup, can only pivot on the side allowing the rider's foot to be released. This retaining device is blocked for a pivoting movement, in particular a pivoting of an angular amplitude limited to 90°, so that this retaining device is prevented from pivoting on the other side of the frame. In the event of a fall of the rider, the tilting of the rider's foot exerts a force on the restraint device which causes it to pass from the closed position to the open position in which this retainer is released, releasing the foot which is no longer retained in the stirrup.
L'invention permet ainsi une grande sécurité pour le cavalier qui s'évite d'être dans des situations dangereuses où, ayant chuté de son cheval, le pied du cavalier est encore pris dans l'étrier. Le déclenchement du dispositif de retenue assure la sécurité du cavalier. Selon l'un des aspects de l'invention, le cadre en forme d'arche comporte une barre supérieure qui définit l'axe de pivotement pour le dispositif de retenue, cette barre supérieure étant de préférence rectiligne. The invention thus allows great safety for the rider who avoids being in dangerous situations where, having fallen from his horse, the rider's foot is still caught in the stirrup. The release of the restraint device ensures the safety of the rider. According to one of the aspects of the invention, the arch-shaped frame comprises an upper bar which defines the pivot axis for the retaining device, this upper bar preferably being rectilinear.
Selon l'un des aspects de l'invention, la barre supérieure comporte une ou deux zones d'attache et le dispositif de retenue comprend un ou deux organes d'attache chacun coopérant, de manière pivotante, avec une zone d'attache de la barre supérieure. According to one of the aspects of the invention, the upper bar comprises one or two attachment zones and the retaining device comprises one or two attachment members each cooperating, in a pivoting manner, with an attachment zone of the upper bar.
Selon l'un des aspects de l'invention, chaque organe d'attache présente une forme en U qui entoure la barre supérieure, dans la zone d'attache, de sorte que cet organe d'attache puisse pivoter sur la barre supérieure. According to one of the aspects of the invention, each attachment member has a U-shape which surrounds the upper bar, in the attachment zone, so that this attachment member can pivot on the upper bar.
Selon l'un des aspects de l'invention, les deux organes d'attache sont identiques. According to one of the aspects of the invention, the two attachment members are identical.
Selon l'un des aspects de l'invention, chaque zone d'attache sur la barre supérieure du cadre est délimitée, à une extrémité, par un épaulement du cadre et, à l'autre extrémité, par une butée formée par exemple par une oreille transversale de la barre supérieure. According to one of the aspects of the invention, each attachment zone on the upper bar of the frame is delimited, at one end, by a shoulder of the frame and, at the other end, by an abutment formed for example by a transverse ear of the upper bar.
Selon l'un des aspects de l'invention, la barre transversale comprend, entre les deux zones d'attache, une zone centrale agencée pour la mise en place d'une étrivière autour de cette barre. According to one of the aspects of the invention, the crossbar comprises, between the two attachment zones, a central zone arranged for the positioning of a stirrup leather around this bar.
Selon l'un des aspects de l'invention, l'étrivière s'étend entre les deux oreilles transversales présentes sur la barre supérieure. According to one of the aspects of the invention, the stirrup leather extends between the two transverse lugs present on the upper bar.
Selon l'un des aspects de l'invention, le dispositif de retenue comporte une plaque qui, en position fermée, s'étend sensiblement dans un même plan que le cadre. According to one of the aspects of the invention, the retaining device comprises a plate which, in the closed position, extends substantially in the same plane as the frame.
Selon l'un des aspects de l'invention, la plaque est attachée à la barre supérieure, de manière pivotante, à l'aide des organes d'attache. According to one of the aspects of the invention, the plate is attached to the upper bar, in a pivoting manner, using attachment members.
Selon l'un des aspects de l'invention, chaque organe d'attache est fixé à la plaque. According to one of the aspects of the invention, each attachment member is fixed to the plate.
Selon l'un des aspects de l'invention, la plaque présente des bords latéraux, notamment courbes, qui épousent sensiblement la forme du cadre. According to one of the aspects of the invention, the plate has lateral edges, in particular curved ones, which substantially match the shape of the frame.
Selon l'un des aspects de l'invention, la plaque présente une forme générale qui s'élargit au fur et à mesure que l'on s'éloigne de la barre supérieure. Selon l'un des aspects de l'invention, la plaque définit avec le support d'appui un espace pour mettre le pied du cavalier. According to one of the aspects of the invention, the plate has a general shape which widens as one moves away from the upper bar. According to one of the aspects of the invention, the plate defines with the support support a space to put the foot of the rider.
Selon l'un des aspects de l'invention, la plaque comprend un bord inférieur dont la forme est incurvée, notamment de forme concave, pour épouser le haut de la chaussure du cavalier. La chaussure du cavalier peut venir en contact avec ce bord de la plaque. La plaque en position fermée permet de limiter l'avancement du pied dans l'étrier. According to one of the aspects of the invention, the plate comprises a lower edge whose shape is curved, in particular of concave shape, to match the top of the rider's shoe. The rider's shoe can come into contact with this edge of the plate. The plate in the closed position makes it possible to limit the advancement of the foot in the stirrup.
Ce bord inférieur peut présenter une symétrie par rapport à un axe de symétrie perpendiculaire à la barre supérieure et passant au milieu de cette barre. This lower edge may have symmetry with respect to an axis of symmetry perpendicular to the upper bar and passing through the middle of this bar.
Autrement dit, cette plaque pourrait être utilisé indifféremment pour un étrier droit ou un étrier gauche. In other words, this plate could be used either for a right caliper or a left caliper.
Selon l'un des aspects de l'invention, la plaque comprend deux faces principales planes. Selon l'un des aspects de l'invention, la plaque est formée par deux flasques assemblées entre elles, chaque face principale plane étant formée sur l'une de ces flasques. Selon l'un des aspects de l'invention, l'assemblage des deux flasques formant la plaque peut être réalisé par soudure, collage ou tout autre technique. According to one of the aspects of the invention, the plate comprises two flat main faces. According to one of the aspects of the invention, the plate is formed by two flanges assembled together, each flat main face being formed on one of these flanges. According to one of the aspects of the invention, the assembly of the two flanges forming the plate can be achieved by welding, gluing or any other technique.
En variante, la plaque peut être réalisée comme une pièce monobloc. Alternatively, the plate can be made as a single piece.
Selon l'un des aspects de l'invention, le dispositif de retenue comporte une palette coulissante qui est réglable en hauteur par rapport à une plaque de retenue du dispositif de retenue, cette palette ayant un bord inférieur agencé pour pouvoir venir en contact avec le pied du cavalier. Ainsi, si le cavalier le souhaite, il peut régler la hauteur de la palette coulissante de sorte que cette palette vienne en contact avec la chaussure. Le cavalier peut, en variante, régler cette hauteur de sorte qu'il subsiste un espace entre sa chaussure et la palette. According to one of the aspects of the invention, the retaining device comprises a sliding pallet which is adjustable in height relative to a retaining plate of the retaining device, this pallet having a lower edge arranged to be able to come into contact with the rider's foot. Thus, if the rider wishes, he can adjust the height of the sliding plate so that this plate comes into contact with the shoe. The rider can, as a variant, adjust this height so that there remains a space between his shoe and the pallet.
Selon l'un des aspects de l'invention, cette palette coulissante est logée et guidée au sein de la plaque, laquelle comprend une fente inférieure à travers laquelle la palette passe. According to one of the aspects of the invention, this sliding pallet is housed and guided within the plate, which comprises a lower slot through which the pallet passes.
Ainsi, en fonction du réglage, la palette s'étend en dehors de la plaque, à travers cette fente, sur une distance plus ou moins grande. Thus, depending on the setting, the pallet extends outside the plate, through this slot, over a greater or lesser distance.
L'invention permet de serrer correctement le pied du cavalier dans l'étrier, à l'aide de cette palette réglable en hauteur. The invention allows the rider's foot to be correctly clamped in the stirrup, using this height-adjustable pallet.
Selon l'un des aspects de l'invention, le dispositif de retenue comprend un organe de réglage pour déplacer la palette par rapport à la plaque, cet organe de réglage comprenant de préférence une molette capable de faire tourner une vis sans fin qui coopère avec la palette de sorte qu'une rotation de la vis permet de déplacer la palette par rapport à la plaque.According to one of the aspects of the invention, the retaining device comprises an adjusting member for moving the pallet relative to the plate, this adjusting member comprising preferably a wheel capable of rotating an endless screw which cooperates with the pallet so that a rotation of the screw makes it possible to move the pallet relative to the plate.
Selon l'un des aspects de l'invention, la molette est actionnable par le cavalier pour régler la position désirée de la palette. Cette molette est par exemple disposée entre les deux organes d'attache de la plaque sur la barre supérieure. According to one of the aspects of the invention, the wheel can be actuated by the rider to adjust the desired position of the pallet. This wheel is for example arranged between the two attachment members of the plate on the upper bar.
Selon l'un des aspects de l'invention, la vis sans fin est logée au sein de la plaque. According to one of the aspects of the invention, the endless screw is housed within the plate.
Selon l'un des aspects de l'invention, la plaque comporte au moins une zone d'arrêt agencée pour venir en appui, en position fermé du dispositif de retenue, sur une butée du cadre de manière à empêcher un pivotement du dispositif de retenue vers le côté du cadre opposé au côté d'engagement du pied. According to one of the aspects of the invention, the plate comprises at least one stop zone arranged to come to rest, in the closed position of the retaining device, on an abutment of the frame so as to prevent pivoting of the retaining device. towards the side of the frame opposite to the foot engagement side.
Selon l'un des aspects de l'invention, le dispositif de retenue comporte un élément mobile agencé pour solidariser le dispositif de retenue au cadre, lorsque que ce dispositif de retenue est en position fermée, cet élément mobile étant capable de se déplacer pour libérer le dispositif de retenue lui permettant de passer en position ouverte. According to one of the aspects of the invention, the retaining device comprises a movable element arranged to secure the retaining device to the frame, when this retaining device is in the closed position, this movable element being able to move to release the retaining device allowing it to pass into the open position.
Selon l'un des aspects de l'invention, cet élément mobile comprend une bille qui est placée dans un logement du dispositif de retenue, notamment de la plaque, et cette bille est soumise à une force élastique capable de pousser la bille dans une cavité du cadre de sorte que la bille soit en partie dans le logement de la plaque et en partie dans la cavité du cadre, de sorte à assurer un blocage de la plaque sur le cadre en position fermée du dispositif de retenue. According to one of the aspects of the invention, this movable element comprises a ball which is placed in a housing of the retaining device, in particular of the plate, and this ball is subjected to an elastic force capable of pushing the ball into a cavity of the frame so that the ball is partly in the housing of the plate and partly in the cavity of the frame, so as to ensure locking of the plate on the frame in the closed position of the retaining device.
Selon l'un des aspects de l'invention, l'effort élastique est assuré par exemple par un ressort logé dans ledit logement de la plaque. According to one of the aspects of the invention, the elastic force is provided for example by a spring housed in said housing of the plate.
La bille peut être libérée de la cavité du cadre lorsqu'une force suffisante est exercée sur la plaque par le pied du cavalier, par exemple en cas de chute de celui-ci. The ball can be released from the cavity of the frame when sufficient force is exerted on the plate by the foot of the rider, for example in the event of a fall of the latter.
La force exercée sur la plaque doit être suffisante pour repousser la bille contre l'effort élastique. Par exemple l'effort pour repousser la bille est de l'ordre de 1kg de pression. La pression de déclenchement peut être différente choisie en fonction de prérequis de sécurité. Ainsi la bille repoussée hors de la cavité du cadre permet de libérer la plaque qui peut alors pivoter, ce qui assure la sécurité du cavalier en cas de chute. The force exerted on the plate must be sufficient to push the ball against the elastic force. For example, the effort to push the ball back is of the order of 1 kg of pressure. The release pressure can be chosen differently depending on safety requirements. Thus the ball pushed out of the cavity of the frame makes it possible to release the plate which can then pivot, which ensures the safety of the rider in the event of a fall.
Selon l'un des aspects de l'invention, la cavité pour recevoir la bille sur le cadre peut être formée par un creusement ou par l'espace ente deux rainures sur le cadre. Selon l'un des aspects de l'invention, deux éléments mobiles, par exemple deux billes, sont prévus chacun sur un bord latéral de la plaque. According to one of the aspects of the invention, the cavity for receiving the ball on the frame can be formed by a hollowing out or by the space between two grooves on the frame. According to one of the aspects of the invention, two movable elements, for example two balls, are each provided on a side edge of the plate.
Selon l'un des aspects de l'invention, le support d'appui est plan et comprend une plaque anti-glissement pour la chaussure du cavalier. According to one of the aspects of the invention, the support support is flat and comprises an anti-slip plate for the rider's shoe.
Selon l'un des aspects de l'invention, le support d'appui comporte un élément de détrompage agencé pour empêcher l'introduction du pied dans l'étrier du côté du cadre opposé au côté de pivotement du dispositif de retenue. According to one of the aspects of the invention, the support support comprises a keying element arranged to prevent the foot from being introduced into the stirrup on the side of the frame opposite to the pivoting side of the retaining device.
Pour des raisons de sécurité, le pied doit être introduit du bon côté de l'étrier pour que le dispositif de retenue puisse fonctionner correctement. For safety reasons, the foot must be inserted on the correct side of the stirrup for the retainer to function correctly.
Selon l'un des aspects de l'invention, cet élément de détrompage comprend une plaquette pivotante sur le support qui est en position relevée par rapport au support lorsque l'étrier n’est pas utilisé et capable d'être rabattue dans un logement du support lorsqu'un pied est introduit dans l'étrier du côté d'engagement. According to one of the aspects of the invention, this keying element comprises a pivoting plate on the support which is in the raised position relative to the support when the stirrup is not in use and capable of being folded back into a housing of the support when a foot is introduced into the stirrup on the engagement side.
Cette plaquette ne peut pas être rabattue sur le support d'appui lorsqu'elle est poussée du mauvais côté, à savoir poussée par le pied qui serait du côté opposé au côté d'engagement. L'invention permet ainsi de s'assurer que le cavalier met son pied à l'étrier du bon côté de celui-ci. This plate cannot be folded down on the support support when it is pushed from the wrong side, namely pushed by the foot which would be on the side opposite the engagement side. The invention thus makes it possible to ensure that the rider puts his foot in the stirrup on the correct side thereof.
Selon l'un des aspects de l'invention, la plaquette est par exemple associée à un ressort permettant de la mettre en mouvement, vers la position relevée par rapport au support d'appui lorsque le pied est retiré de l'étrier. According to one of the aspects of the invention, the plate is for example associated with a spring making it possible to set it in motion, towards the raised position relative to the support support when the foot is removed from the stirrup.
Dans un autre exemple de réalisation de l'invention, qui est préféré, le dispositif de retenue pivotant, notamment pourvu d'une plaque, comporte un élément de détrompage. In another exemplary embodiment of the invention, which is preferred, the pivoting retaining device, in particular provided with a plate, comprises a keying element.
Dans ce cas, le support d'appui est avantageusement dépourvu d'élément de détrompage. Selon l'un des aspects de l'invention, l'élément de détrompage est porté par la plaque du dispositif de retenue. In this case, the bearing support is advantageously devoid of foolproofing element. According to one of the aspects of the invention, the keying element is carried by the plate of the retaining device.
Selon l'un des aspects de l'invention, l'élément de détrompage est monté pivotant sur cette plaque du dispositif de retenue, par exemple à l'aide d'un axe de pivotement logé dans la plaque. According to one of the aspects of the invention, the keying element is pivotally mounted on this plate of the retaining device, for example using a pivot pin housed in the plate.
Avantageusement, l'élément de détrompage est monté pivotant sur cette plaque du dispositif de retenue, du côté interdit au pied du cavalier. Advantageously, the keying element is pivotally mounted on this plate of the retaining device, on the side prohibited from the rider's foot.
Avantageusement, en position verticale de l'étrier, l'élément de détrompage est en position verticale, par son propre poids, en repos gravitaire. Dans cette situation, l'élément de détrompage fait saillie vers le bas, et occupe un espace vertical entre la plaque du dispositif de retenue et le support d'appui. Advantageously, in the vertical position of the stirrup, the keying element is in the vertical position, by its own weight, at rest by gravity. In this situation, the element of keying protrudes downward, and occupies a vertical space between the retainer plate and the bearing bracket.
Avantageusement, l'élément de détrompage ne peut pivoter que d'un côté, à savoir le côté autorisé. Autrement dit, l'élément de détrompage est configuré pour pouvoir pivoter pour laisser passer le pied du cavalier seulement lorsque celui-ci est introduit du bon côté (le côté autorisé) de l'étrier. Advantageously, the keying element can only pivot on one side, namely the authorized side. In other words, the keying element is configured to be able to pivot to allow the rider's foot to pass only when the latter is introduced on the correct side (the authorized side) of the stirrup.
Avantageusement, l'élément de détrompage est interdit de pivoter lorsqu'il est poussé du côté interdit, notamment par butée de l'élément de détrompage contre la plaque. Ainsi cette impossibilité de rotation lorsque le pied du cavalier est introduit du mauvais côté, bloque toute tentative de chausser à l'envers, ce qui constitue une solide sécurité pour le cavalier qui utilise l'étrier selon l'invention. Advantageously, the keying element is prevented from pivoting when it is pushed on the prohibited side, in particular by abutment of the keying element against the plate. Thus, this impossibility of rotation when the rider's foot is introduced on the wrong side, blocks any attempt to put on the shoes upside down, which constitutes solid security for the rider who uses the stirrup according to the invention.
De plus, l'élément de détrompage ne génère pas de résistance lors de la chute du cavalier, permettant de libérer le pied du cavalier en toute sécurité. In addition, the keying element does not generate resistance when the rider falls, allowing the rider's foot to be released safely.
Selon l'un des aspects de l'invention, l'élément de détrompage se présente sous la forme d'un médaillon monté sur le dispositif de retenue. L'élément de détrompage est par exemple en matière plastique ou métallique. L'élément de détrompage est avantageusement rigide. According to one of the aspects of the invention, the keying element is in the form of a medallion mounted on the retaining device. The keying element is for example made of plastic or metal. The keying element is advantageously rigid.
Selon l'un des aspects de l'invention, la plaque du dispositif de retenue est une plaque pleine. According to one of the aspects of the invention, the plate of the retaining device is a solid plate.
Avantageusement, le support d'appui comporte une surface amortissante sur laquelle s'appuie la chaussure du cavalier. Cette surface amortissante est plane, de préférence sans mécanisme ou pièce mobile. En variante, cette surface amortissante est bombée. Le cas échéant, le support d'appui peut comporter une poche gonflable, par exemple en étant raccordable à une pompe externe, notamment de type pompe pour gonfler une chambre à air de vélo. Cette poche gonflable forme la surface amortissante sur laquelle s'appuie la chaussure du cavalier. Dans ce cas, la surface amortissante est en matériau souple, par exemple en caoutchouc. Ainsi il est possible de gonfler plus ou moins cette poche, ce qui permet d'ajuster le niveau d'amortissement choisi par le cavalier. Advantageously, the support support comprises a damping surface on which the rider's shoe rests. This damping surface is flat, preferably without any mechanism or moving part. As a variant, this damping surface is curved. Where appropriate, the support support may comprise an inflatable pocket, for example by being connectable to an external pump, in particular of the pump type for inflating a bicycle inner tube. This inflatable pocket forms the shock-absorbing surface on which the rider's shoe rests. In this case, the damping surface is made of flexible material, for example rubber. Thus it is possible to inflate this pocket more or less, which makes it possible to adjust the level of damping chosen by the rider.
Avantageusement, le cadre en forme d'arche est fermé, en bas, par une poutre faisant partie du support d'appui. Le cadre en forme d'arche et cette poutre peuvent être faits d'une seule pièce, par exemple une pièce de fonderie. Ceci est particulièrement avantageux en termes de tenue mécanique. Le dispositif de retenue muni de l'élément de détrompage peut comporter ou non une palette coulissante réglable en hauteur. Autrement dit, la plaque peut être simple, sans offrir de possibilité de réglage en hauteur, ou, en variante, comporter une palette réglable en hauteur. Advantageously, the arch-shaped frame is closed, at the bottom, by a beam forming part of the bearing support. The arch-shaped frame and this beam can be made from a single piece, for example a casting. This is particularly advantageous in terms of mechanical strength. The retaining device provided with the keying element may or may not include a height-adjustable sliding pallet. In other words, the plate can be simple, without offering the possibility of height adjustment, or, as a variant, comprise a height-adjustable pallet.
Selon l'un des aspects de l'invention, le corps peut être en métal ou en matériau composite. La plaque peut être en métal ou en matière plastique par exemple. According to one of the aspects of the invention, the body can be made of metal or of a composite material. The plate can be made of metal or plastic material for example.

On a représenté sur les figures 1 et 2 un premier exemple de réalisation de l'invention relatif à un étrier de sécurité 1 pour l'équitation. There is shown in Figures 1 and 2 a first embodiment of the invention relating to a safety stirrup 1 for horse riding.
Cet étrier 1 comporte un corps 2 pourvu d'un support d'appui 3 pour un pied d'un cavalier qui est sur un cheval. Le corps 2 est en outre pourvu d'un cadre 4 en forme d'arche. This stirrup 1 comprises a body 2 provided with a support support 3 for a foot of a rider who is on a horse. The body 2 is further provided with a frame 4 in the form of an arch.
L'étrier 1 comporte un dispositif de retenue 5 du pied, monté pivotant sur le cadre 4 entre une position fermée, illustrée sur la figure 1, dans laquelle le dispositif de retenue 5 est enclenché de sorte que ce dispositif de retenue 5 soit solidarisé au cadre 4 et une position ouverte, illustrée sur la figure 2, dans laquelle le dispositif de retenue 5 est déclenché de manière à être pivotable par rapport au cadre 4, autour d'un axe de pivotement X, suivant un mouvement de pivotement limité à un seul côté 6 du cadre, ce côté de pivotement 6 étant le côté d'engagement du pied par lequel le pied du cavalier s'engage dans l'étrier 1. La direction d'engagement du pied dans l'étrier 1 est matérialisé par la flèche 7 sur la figure 1. The stirrup 1 comprises a retaining device 5 for the foot, pivotally mounted on the frame 4 between a closed position, illustrated in FIG. 1, in which the retaining device 5 is engaged so that this retaining device 5 is secured to the frame 4 and an open position, illustrated in Figure 2, in which the retaining device 5 is released so as to be pivotable relative to the frame 4, around a pivot axis X, following a pivoting movement limited to one only side 6 of the frame, this pivoting side 6 being the foot engagement side by which the rider's foot engages in the stirrup 1. The direction of engagement of the foot in the stirrup 1 is materialized by the arrow 7 in figure 1.
Le dispositif de retenue 5 est agencé pour se déclencher en cas de basculement du pied du cavalier, par exemple en cas de chute du cavalier, de sorte à libérer le pied du cavalier.The retaining device 5 is arranged to be triggered in the event of the rider's foot tipping over, for example in the event of the rider falling, so as to release the rider's foot.
Le dispositif de retenue 5 ne peut pivoter que du côté 6 permettant de libérer le pied du cavalier. Ce dispositif de retenue 5 est bloqué pour un mouvement de pivotement de l'autre côté du cadre 4. En cas de chute du cavalier, le basculement du pied du cavalier vient exercer sur le dispositif de retenue 5 une force qui le fait passer de la position fermée à la position ouverte dans laquelle ce dispositif de retenue 5 est déclenché, libérant le pied qui n'est plus retenu sur l'étrier 1. The retaining device 5 can only pivot on the side 6 allowing the rider's foot to be released. This retaining device 5 is blocked for a pivoting movement on the other side of the frame 4. In the event of the rider falling, the tilting of the rider's foot exerts on the retaining device 5 a force which causes it to pass from the closed position to the open position in which this retaining device 5 is released, releasing the foot which is no longer retained on the stirrup 1.
Le cadre 4 en forme d'arche comporte une barre supérieure rectiligne 9 qui définit l'axe de pivotement X pour le dispositif de retenue 5. The arch-shaped frame 4 has a straight top bar 9 which defines the pivot axis X for the retainer 5.
La barre supérieure 9 comporte deux zones d'attache 10 et le dispositif de retenue 5 comprend deux organes d'attache 11 chacun coopérant, de manière pivotante, avec une zone d'attache 10 de la barre supérieure 9. The upper bar 9 comprises two attachment zones 10 and the retaining device 5 comprises two attachment members 11 each cooperating, in a pivoting manner, with an attachment zone 10 of the upper bar 9.
Chaque organe d'attache 11 présente une forme en U qui entoure la barre supérieure 9, dans la zone d'attache 10, de sorte que cet organe d'attache puisse pivoter sur la barre supérieure 9. Each attachment member 11 has a U-shape which surrounds the upper bar 9, in the attachment zone 10, so that this attachment member can pivot on the upper bar 9.
Les deux organes d'attache 11 sont identiques. The two attachment members 11 are identical.
Chaque zone d'attache 10 sur la barre supérieure 9 est délimitée, à une extrémité, par un épaulement 12 du cadre 4 et, à l'autre extrémité, par une butée formée par une oreille transversale 14 de la barre supérieure 9, comme bien visible sur la figure 2. Each attachment zone 10 on the upper bar 9 is delimited, at one end, by a shoulder 12 of the frame 4 and, at the other end, by a stop formed by a transverse lug 14 of the upper bar 9, as well seen in figure 2.
Chaque organe d'attache 11 est ainsi immobilisé selon l'axe X par l'épaulement 12 et l'oreilleEach attachment member 11 is thus immobilized along the X axis by the shoulder 12 and the lug
14. La barre supérieure 9 comprend, entre les deux zones d'attache 10, une zone centrale 15 agencée pour la mise en place d'une étrivière, non représentée, autour de cette barre 9. L'étrivière s'étend entre les deux oreilles transversales 14. 14. The upper bar 9 comprises, between the two attachment zones 10, a central zone 15 arranged for the establishment of a stirrup leather, not shown, around this bar 9. The stirrup leather extends between the two transverse lugs 14.
Le dispositif de retenue 5 comporte une plaque 17 qui, en position fermée, s'étend sensiblement dans un même plan que le cadre 4, comme illustré sur la figure 1. The retaining device 5 comprises a plate 17 which, in the closed position, extends substantially in the same plane as the frame 4, as illustrated in Figure 1.
La plaque 17 est attachée à la barre supérieure 9, de manière pivotante, à l'aide des organes d'attache 11. The plate 17 is attached to the upper bar 9, in a pivoting manner, using the attachment members 11.
Les organes d'attache 11 sont fixés à la plaque 17. The attachment members 11 are fixed to the plate 17.
La plaque 17 présente des bords latéraux courbes 18, qui épousent sensiblement la forme du cadre 4. The plate 17 has curved side edges 18, which substantially match the shape of the frame 4.
La plaque 17 présente une forme générale qui s'élargit au fur et à mesure que l'on s'éloigne de la barre supérieure 9. The plate 17 has a general shape which widens as one moves away from the upper bar 9.
La plaque 17 définit avec le support d'appui 3 un espace 19 pour mettre le pied du cavalier.The plate 17 defines with the support support 3 a space 19 to put the rider's foot.
La plaque 17 comprend un bord inférieur 20 dont la forme est incurvée, notamment de forme concave avec la concavité dirigée vers le support d'appui 3, pour épouser le haut de la chaussure du cavalier. The plate 17 comprises a lower edge 20 whose shape is curved, in particular of concave shape with the concavity directed towards the support support 3, to match the top of the rider's shoe.
La chaussure du cavalier peut venir en contact avec ce bord 20 de la plaque 17 qui, en position fermée, permet de maintenir le pied correctement dans l'étrier 1. The rider's shoe can come into contact with this edge 20 of the plate 17 which, in the closed position, allows the foot to be held correctly in the stirrup 1.
Ce bord inférieur 20 peut présenter une symétrie par rapport à un axe de symétrie perpendiculaire à la barre supérieure et passant au milieu de cette barre. This lower edge 20 may have symmetry with respect to an axis of symmetry perpendicular to the upper bar and passing through the middle of this bar.
Autrement dit, cette plaque pourrait être utilisé indifféremment pour un étrier droit ou un étrier gauche. In other words, this plate could be used either for a right caliper or a left caliper.
En variante, le bord 20 peut être dissymétrique. As a variant, the edge 20 can be asymmetrical.
La plaque 17 comprend deux faces principales planes 21. Plate 17 comprises two flat main faces 21.
La plaque 17 est formée par deux flasques 22 assemblées entre elles, chaque face principale 21 plane étant formée sur l'une de ces flasques 22. Plate 17 is formed by two flanges 22 assembled together, each flat main face 21 being formed on one of these flanges 22.
L'assemblage des deux flasques 22 formant la plaque peut être réalisé par soudure, collage ou tout autre technique. The assembly of the two flanges 22 forming the plate can be achieved by welding, gluing or any other technique.
En variante, la plaque 17 peut être réalisée comme une pièce monobloc. Alternatively, the plate 17 can be made as a single piece.
Le corps 2 peut être en métal ou en matériau composite, en une seule pièce ou plusieurs pièces. The body 2 can be made of metal or of a composite material, in a single piece or in several pieces.
La plaque 17 peut être en métal ou en matière plastique par exemple. Comme cela est visible sur la figure 2, le dispositif de retenue 5 comporte deux éléments mobiles 23 agencés pour solidariser le dispositif de retenue 5 au cadre 4, lorsque que ce dispositif de retenue 5 est en position fermée, chaque élément mobile 23 étant capable de se déplacer pour libérer le dispositif de retenue 5 lui permettant de passer en position ouverte. The plate 17 can be made of metal or of plastic material for example. As can be seen in FIG. 2, the retaining device 5 comprises two movable elements 23 arranged to secure the retaining device 5 to the frame 4, when this retaining device 5 is in the closed position, each movable element 23 being capable of move to release the retainer 5 allowing it to pass into the open position.
Le fonctionnement de ces éléments mobiles 23 sera mieux décrit plus bas, dans l'exemple de réalisation suivant. The operation of these mobile elements 23 will be better described below, in the following example embodiment.
Le support d'appui 3 est plan et comprend une plaque anti-glissement 24 pour la chaussure du cavalier. The support support 3 is flat and includes an anti-slip plate 24 for the rider's shoe.
Le support d'appui 3 comporte un élément de détrompage 25 agencé pour empêcher l'introduction du pied dans l'étrier 1 du côté du cadre 4 opposé au côté de pivotement 6 du dispositif de retenue 5. The support support 3 comprises a keying element 25 arranged to prevent the introduction of the foot into the stirrup 1 on the side of the frame 4 opposite the pivoting side 6 of the retaining device 5.
Cet élément de détrompage 25 comprend une plaquette pivotante 26, avec un pourtour externe arrondi, qui est en position relevée par rapport au support 3 lorsque l'étrier 1 n’est pas utilisé et capable d'être rabattue dans un logement 27 du support 3 lorsqu'un pied est introduit dans l'étrier 1 du côté d'engagement 6. This keying element 25 comprises a pivoting plate 26, with a rounded outer periphery, which is in the raised position relative to the support 3 when the stirrup 1 is not used and capable of being folded into a housing 27 of the support 3 when a foot is introduced into the stirrup 1 on the engagement side 6.
Cette plaquette 26 ne peut pas être rabattue sur le support d'appui 3 lorsqu'elle est poussée du mauvais côté, à savoir poussée par le pied qui serait du côté opposé au côté d'engagement 6. This plate 26 cannot be folded down on the support support 3 when it is pushed from the wrong side, namely pushed by the foot which would be on the side opposite to the engagement side 6.
L'invention permet ainsi de s'assurer que le cavalier met son pied à l'étrier 1 du bon côté de celui-ci. The invention thus makes it possible to ensure that the rider puts his foot in the stirrup 1 on the correct side thereof.
Le support d'appui 3 comprend un bouton 38 qui coopère avec la plaquette pivotante 26 par l'intermédiaire d'un mécanisme, non représenté, logé dans le support d'appui 3 et pourvu d'un ressort et de bras actionnables par ce ressort, ce mécanisme étant agencé de sorte que, lorsque le bouton 38 est enfoncé suite à un appui avec la chaussure du cavalier, ce bouton 38 actionne ce mécanisme dont la cinématique permet d'abaisser la plaquette pivotante 26 (figure 2). The support support 3 comprises a button 38 which cooperates with the pivoting plate 26 via a mechanism, not shown, housed in the support support 3 and provided with a spring and arms actuated by this spring. , this mechanism being arranged so that, when the button 38 is pressed following pressure with the rider's shoe, this button 38 actuates this mechanism, the kinematics of which makes it possible to lower the pivoting plate 26 (FIG. 2).
Quand le bouton 38 est relâché, ce bouton 38 remonte et le mécanisme, animé par des efforts de rappel élastique, relève la plaquette pivotante 26 dans sa position relevée (figure 1). When the button 38 is released, this button 38 rises and the mechanism, driven by elastic return forces, lifts the pivoting plate 26 into its raised position (FIG. 1).
On va maintenant décrire en référence aux figures 3 à 6 un étrier 30 selon un deuxième exemple de réalisation de l'invention. Les parties similaires entre l'étrier 1 décrit précédemment et l'étrier 30 ne seront pas reprises dans la description qui suit. A description will now be given with reference to FIGS. 3 to 6 of a stirrup 30 according to a second embodiment of the invention. The similar parts between the stirrup 1 described above and the stirrup 30 will not be repeated in the following description.
L'étrier 30 diffère de l'étrier 1 de l'exemple précédent, par le fait que l'étrier 30 comprend un dispositif de retenue 31 qui comporte une palette coulissante 32 qui est réglable en hauteur par rapport à une plaque de retenue 47. Stirrup 30 differs from stirrup 1 of the previous example, in that stirrup 30 comprises a retainer 31 which includes a sliding pallet 32 which is height adjustable relative to a retainer plate 47.
Comme illustré sur la figure 4, cette palette 32 présente un bord inférieur 33 agencé pour pouvoir venir en contact avec le pied du cavalier. As illustrated in Figure 4, this pallet 32 has a lower edge 33 arranged to be able to come into contact with the rider's foot.
Ce bord inférieur 33 est dissymétrique pour se conformer à la forme de la chaussure du cavalier. This lower edge 33 is asymmetrical to conform to the shape of the rider's shoe.
Cette palette coulissante 32 est logée et guidée au sein de la plaque 47, laquelle comprend une fente inférieure 34 à travers laquelle la palette 32 passe. This sliding pallet 32 is housed and guided within the plate 47, which includes a lower slot 34 through which the pallet 32 passes.
Ainsi, en fonction du réglage, la palette 32 s'étend en dehors de la plaque 47, à travers cette fente 34, sur une distance plus ou moins grande. Thus, depending on the setting, the pallet 32 extends outside the plate 47, through this slot 34, over a greater or lesser distance.
L'invention permet, si on le souhaite, de serrer correctement le pied du cavalier dans l'étrier 30, à l'aide de cette palette 32 réglable en hauteur. The invention makes it possible, if desired, to clamp the rider's foot correctly in the stirrup 30, using this height-adjustable pallet 32.
Le dispositif de retenue comprend un organe de réglage 35 pour déplacer la palette 32 par rapport à la plaque 47. The retainer includes an adjuster 35 to move the pallet 32 relative to the plate 47.
Comme visible sur la figure 6, cet organe de réglage 35 comprend une molette 36 capable de faire tourner une vis sans fin 37 qui coopère avec la palette 32 de sorte qu'une rotation de la vis 37 permet de déplacer la palette 32 par rapport à la plaque 47. As visible in Figure 6, this adjustment member 35 comprises a knob 36 capable of rotating an endless screw 37 which cooperates with the pallet 32 so that a rotation of the screw 37 makes it possible to move the pallet 32 with respect to plate 47.
La vis sans fin 37 est vissée dans un taraudage 38 de la palette 32. The endless screw 37 is screwed into a thread 38 of the pallet 32.
Cette palette 32 peut être réalisée par l'assemblage de deux flasques 39. This pallet 32 can be made by assembling two flanges 39.
La molette 36 est actionnable par le cavalier pour régler la position désirée de la palette 32. Cette molette 36 est disposée entre les deux organes d'attache 11 de la plaque sur la barre supérieure 9. The wheel 36 can be actuated by the rider to adjust the desired position of the pallet 32. This wheel 36 is arranged between the two attachment members 11 of the plate on the upper bar 9.
La vis sans fin 37 est logée au sein de la plaque 47. The endless screw 37 is housed within the plate 47.
La plaque 47 comporte, sur chaque bord latéral 18, une zone d'arrêt 40 agencée pour venir en appui, en position fermée du dispositif de retenue, sur une butée 41 du cadre 4 de manière à empêcher un pivotement du dispositif de retenue 31 vers le côté du cadre opposé au côté d'engagement 6 du pied. Ces zones d'arrêt 40 et butées 41 sont présentes également sur le dispositif de retenue 5 de l'exemple précédent. Les figures 3 et 4 montrent le dispositif de retenue 31 en positon fermée. Dans la figure 4, la palette 32 est en descendue par rapport à la plaque 47. The plate 47 comprises, on each lateral edge 18, a stop zone 40 arranged to come to rest, in the closed position of the retaining device, on an abutment 41 of the frame 4 so as to prevent pivoting of the retaining device 31 towards the side of the frame opposite the engagement side 6 of the foot. These stop zones 40 and stops 41 are also present on the retaining device 5 of the previous example. Figures 3 and 4 show the retainer 31 in the closed position. In figure 4, the pallet 32 is descended with respect to the plate 47.
La figure 5 montre le dispositif de retenue 31 en positon ouverte. Figure 5 shows retainer 31 in the open position.
Chaque élément mobile 23 est une bille qui est placée dans un logement 28 du dispositif de la plaque 47 ou de la plaque 17 de l'exemple précédent, et cette bille 23 est soumise à une force élastique capable de pousser la bille dans une cavité 29 du cadre 4 de sorte que la bille 23 soit en partie dans le logement 28 de la plaque et en partie dans la cavité 29 du cadre, de sorte à assurer un blocage de la plaque 47 sur le cadre 4 en position fermée du dispositif de retenue 31. Each movable element 23 is a ball which is placed in a housing 28 of the device of the plate 47 or of the plate 17 of the previous example, and this ball 23 is subjected to an elastic force capable of pushing the ball into a cavity 29 of the frame 4 so that the ball 23 is partly in the housing 28 of the plate and partly in the cavity 29 of the frame, so as to ensure locking of the plate 47 on the frame 4 in the closed position of the retaining device 31.
L'effort élastique est assuré par un ressort, non représenté, logé dans ledit logement 28 de la plaque 47. The elastic force is provided by a spring, not shown, housed in said housing 28 of plate 47.
La bille 23 peut être libérée de la cavité 29 du cadre lorsqu'une force suffisante est exercée sur la plaque 47 par le pied du cavalier, par exemple en cas de chute de celui-ci. The ball 23 can be released from the cavity 29 of the frame when sufficient force is exerted on the plate 47 by the foot of the rider, for example in the event of a fall thereof.
La force exercée sur la plaque 47 doit être suffisante pour repousser la bille contre l'effort élastique. The force exerted on the plate 47 must be sufficient to push the ball against the elastic force.
La pression de déclenchement peut être différente choisie en fonction de prérequis de sécurité. The release pressure can be chosen differently depending on safety requirements.
Ainsi la bille 23 repoussée hors de la cavité 29 du cadre permet de libérer la plaque 47 qui peut alors pivoter, ce qui assure la sécurité du cavalier en cas de chute. Thus the ball 23 pushed back out of the cavity 29 of the frame makes it possible to release the plate 47 which can then pivot, which ensures the rider's safety in the event of a fall.
La cavité 29 pour recevoir la bille sur le cadre 4 peut être formée par un creusement ou par l'espace ente deux rainures 44 sur le cadre. The cavity 29 to receive the ball on the frame 4 can be formed by a hollowing out or by the space between two grooves 44 on the frame.
Lors de l'utilisation de l'étrier 1, si le pied en bonne position dans l'étrier ne heurte pas le dispositif de retenue, le cavalier peut quitter naturellement ses étriers, sans déclencher le dispositif de retenue 31. When using the stirrup 1, if the foot in the correct position in the stirrup does not hit the retainer, the rider can naturally leave his stirrups, without triggering the retainer 31.
Si le pied est trop enfoncé dans l'étrier, ou le dispositif de retenue 31 est volontairement serré sur la chaussure du cavalier, le dispositif de retenue 31 se déclenchera au retrait du pied. If the foot is pushed too far into the stirrup, or the retainer 31 is intentionally tight on the rider's shoe, the retainer 31 will release when the foot is removed.
D'une manière générale, l'étrivière de liaison entre la selle et l'étrier subit une tension qui est de nature à libérer le ou les pieds du cavalier bloqués par inadvertance ou volontairement dans l'étrier 30. Le déclenchement du dispositif de retenue 31 sera commandé automatiquement par la chute du cavalier. Dans l'exemple décrit, l'étrier droit et l'étrier gauche peuvent être fabriqués à partir des mêmes pièces. La seule distinction entre un étrier droit et un étrier gauche est l'orientation de la palette coulissante 32 avec son bord 33 dissymétrique. Lors de la fabrication, cette palette 32 est montée avec des orientations respectivement opposées sur l'étrier droit et l'étrier gauche. Ainsi le bord 33 est adapté à la forme de la chaussure de droite sur l'étrier droit, et le bord 33 est adapté à la forme de la chaussure de gauche sur l'étrier gauche. Cette palette 32, en tant que pièce, est la même sur l'étrier droit et l'étrier gauche. In general, the stirrup leather connecting the saddle and the stirrup is subjected to a tension which is likely to release the foot or feet of the rider blocked inadvertently or voluntarily in the stirrup 30. The triggering of the restraint device 31 will be controlled automatically by the fall of the jumper. In the example described, the right caliper and the left caliper can be made from the same parts. The only distinction between a right stirrup and a left stirrup is the orientation of the sliding pallet 32 with its asymmetrical edge 33. During manufacture, this pallet 32 is mounted with respectively opposite orientations on the right caliper and the left caliper. Thus the edge 33 is adapted to the shape of the right shoe on the right stirrup, and the edge 33 is adapted to the shape of the left shoe on the left stirrup. This pallet 32, as a part, is the same on the right caliper and the left caliper.
Dans un autre exemple de réalisation de l'invention illustré sur les figures 7 et 8, qui est préféré, le dispositif de retenue 31 qui comporte la palette coulissante 32 réglable en hauteur, est pourvu d'un élément de détrompage 50. In another exemplary embodiment of the invention illustrated in Figures 7 and 8, which is preferred, the retaining device 31 which includes the sliding pallet 32 adjustable in height, is provided with a keying element 50.
Dans ce cas, le support d'appui 3 est avantageusement dépourvu d'élément de détrompage. L'élément de détrompage 50 est monté pivotant sur la plaque 47 du dispositif de retenue 31, à l'aide d'un axe de pivotement logé dans la plaque 47. In this case, the bearing support 3 is advantageously devoid of foolproofing element. Keying element 50 is pivotally mounted on plate 47 of retaining device 31, using a pivot pin housed in plate 47.
L'élément de détrompage 50 est monté pivotant sur cette plaque 47, du côté interdit au pied du cavalier. The keying element 50 is pivotally mounted on this plate 47, on the side forbidden at the rider's foot.
En position verticale de l'étrier, l'élément de détrompage 50 est en position verticale, par son propre poids, en repos gravitaire, comme illustré sur la figure 7. Dans cette situation, l'élément de détrompage 50 fait saillie vers le bas, et occupe un espace vertical entre la plaque 47 du dispositif de retenue et le support d'appui 3. In the vertical position of the caliper, the keying element 50 is in the vertical position, by its own weight, in gravity rest, as illustrated in FIG. 7. In this situation, the keying element 50 protrudes downwards , and occupies a vertical space between the plate 47 of the retaining device and the bearing support 3.
L'élément de détrompage 50 ne peut pivoter que d'un côté, à savoir le côté autorisé. Autrement dit, l'élément de détrompage 50 est configuré pour pouvoir pivoter pour laisser passer le pied du cavalier seulement lorsque celui-ci est introduit du bon côté (le côté autorisé) de l'étrier. C'est ce qui est illustré sur la figure 8 avec le médaillon 50 qui est relevé du bon côté permettant au cavalier de chausser l'étrier. The keying element 50 can only pivot on one side, namely the authorized side. In other words, the keying element 50 is configured to be able to pivot to allow the rider's foot to pass only when the latter is introduced on the correct side (the authorized side) of the stirrup. This is what is illustrated in Figure 8 with the medallion 50 which is raised on the right side allowing the rider to put on the stirrup.
L'élément de détrompage 50 est interdit de pivoter lorsqu'il est poussé du côté interdit, notamment par butée de l'élément de détrompage 50 contre la plaque 47. Ainsi cette impossibilité de rotation lorsque le pied du cavalier est introduit du mauvais côté, bloque toute tentative de chausser à l'envers, ce qui constitue une solide sécurité pour le cavalier qui utilise l'étrier selon l'invention. The keying element 50 is prevented from pivoting when it is pushed on the prohibited side, in particular by abutment of the keying element 50 against the plate 47. Thus this impossibility of rotation when the rider's foot is introduced on the wrong side, blocks any attempt to put on upside down, which constitutes solid security for the rider who uses the stirrup according to the invention.
De plus, l'élément de détrompage 50 ne génère pas de résistance lors de la chute du cavalier, permettant de libérer le pied du cavalier en toute sécurité. L'élément de détrompage 50 se présente sous la forme d'un médaillon monté sur le dispositif de retenue 31. L'élément de détrompage 50 est par exemple en matière plastique ou métallique. L'élément de détrompage 50 est avantageusement rigide. In addition, the keying element 50 does not generate resistance when the rider falls, allowing the rider's foot to be released in complete safety. The keying element 50 is in the form of a medallion mounted on the retaining device 31. The keying element 50 is for example made of plastic or metal. The keying element 50 is advantageously rigid.
Dans l'exemple décrit, le support d'appui 3 comporte une surface amortissante 54 sur laquelle s'appuie la chaussure du cavalier. Cette surface amortissante 54 est plane, sans mécanisme ou pièce mobile qui s'y loge. In the example described, the support support 3 comprises a damping surface 54 on which the rider's shoe rests. This damping surface 54 is flat, with no mechanism or moving part lodged therein.
Le cadre 4 en forme d'arche est fermé, en bas, par une poutre faisant partie du support d'appui 3. Le cadre 4 en forme d'arche et cette poutre peuvent être faits d'une seule pièce, par exemple une pièce de fonderie. Ceci est particulièrement avantageux en termes de tenue mécanique. The arch-shaped frame 4 is closed, at the bottom, by a beam forming part of the bearing support 3. The arch-shaped frame 4 and this beam can be made in one piece, for example a piece of foundry. This is particularly advantageous in terms of mechanical strength.
Le dispositif de retenue muni de l'élément de détrompage peut comporter ou non une palette coulissante 32 réglable en hauteur. Autrement dit, la plaque peut être simple, sans offrir de possibilité de réglage en hauteur, ou, en variante, comporter une palette réglable en hauteur. Le support d'appui 3 peut, en variante, présenter une forme illustrée sur la figure 9. Dans cet exemple, le support d'appui 3 comprend des nervures de renfort 59 parallèles, sur le dessous. Ceci permet d'avoir un support d'appui 3 à la fois solide et plus léger. The retaining device provided with the keying element may or may not include a sliding pallet 32 adjustable in height. In other words, the plate can be simple, without offering the possibility of height adjustment, or, as a variant, comprise a height-adjustable pallet. The bearing support 3 may, as a variant, have a shape illustrated in FIG. 9. In this example, the bearing support 3 comprises reinforcing ribs 59 which are parallel, on the underside. This makes it possible to have a support support 3 that is both solid and lighter.
