Definitions
- the present invention relates to a retaining device for obstacle bars, in particular of the kind used for training and competition in show jumping of horses.
- Such obstacles consist of a movable bar, the ends of which rest on arches which are integral with a frame making it possible to place them at the desired location of supports which offer staggered positions for these frames.
- the supports consist of vertical posts, often called candlesticks, which are drilled with staggered holes.
- These supports can also be produced by means of horizontal or oblique bars also pierced with staggered holes.
- the frame can be constituted by a cleat comprising one or two pins pluggable into the holes of the support.
- This frame may also include a collar enclosing the post and which is retained in staggered notches placed at the edges thereof.
- the aforementioned arch is often in the form of a quarter of a circle and it is integral with a part of the frame situated opposite the opposite post, so that the plane of this arch is vertical and parallel to the plane of symmetry of the obstacle.
- the present invention aims to avoid these dangers and disadvantages and to ensure both the fall of the bar, as soon as it is struck, and the precision of its positioning.
- the obstacle bar retainer comprising a frame intended to be fixed in an adjustable location of a candlestick or the like, this frame carrying a U-shaped piece serving as a support for the bar, is characterized in that that said support can pivot around at least one axis of the frame parallel to the bar when the latter is in the service position in the supports.
- the invention thus makes it possible to produce a retractable safety bar support.
- the device according to the invention also comprises means tending to return the U-shaped support of the bar to its normal operating position, that is to say corresponding to the retention of the bar.
- return means can be, in particular, of an elastic nature.
- the bar support has a well-defined normal service position, and the same goes for the bar height.
- it in the event of pivoting under the effect of an impact, it can be automatically brought back to this normal operating position.
- the U-shaped support of the bar is fixed to one of the plates of a simple hinge whose axis is parallel to the pin of a cleat, intended to be inserted in a hole a candlestick or the like, the other plate being integral with this pin and serving as a stop for the support of the bar in the normal service position.
- the simple hinge is replaced by a double hinge and the U-shaped support of the bar is fixed to the first of the hinge plates whose axes are parallel to the pin of a cleat, the second plate connecting the two axes and the third plate being integral with this pin, and serving as a stop for the support of the bar, in the normal service position.
- the three plates are stacked one on the other, and the upper plate carrying the U-shaped support can tilt to the right or to the left.
- This embodiment allows the bilateral crossing of obstacles.
- the retaining device comprises a lateral support plate for the bar, parallel to the U-shaped support, integral with the latter, and disposed between said support and cleat.
- the bar is contained in the interval between the two lateral support plates, and as these plates are integral with the supports U-shaped and tilt with them, any wedging of the bar against the candlesticks is made impossible.
- the U-shaped support of the bar extends substantially over a semicircle.
- the retaining device is of the type in which the frame comprises a metal cleat constituted by a straight pin 1 with its extension 1a, and by a pin 2 parallel to the previous one, bent at right angles in its part 2a welded to the spindle 1.
- a support 6 in the shape of a U is placed at the front of the cleat, its median plane is vertical in the normal operating position, and perpendicular to the plane of pins 1 and 2, also vertical and forming plane of symmetry of support 6.
- the U 6 support which develops substantially on a semicircle, is welded to the upper plate 5 of a simple hinge whose axis 3 parallel to the pin 1 ends at the front by a head 3a, and at the rear by a frustoconical collar 3b, obtained for example by stamping.
- the lower plate 4 of the hinge is welded to the extension of the spindle 1 and serves as a stop for the plate 5 in the normal service position.
- a vertical plate 7, serving as a lateral support for the obstacle bar, is welded to the upper plate 5 of the hinge, parallel to the U-shaped support 6.
- An elastomer strap placed between the U-shaped support 6 and the plate 7, surrounds the two plates 4 and 5 and the axis 3 of the hinge, passing in the extension of the spindle 1.
- the pins 1 and 2 are threaded in the staggered holes 10 of a candlestick 21, or other ( Figure 5), and the obstacle bar 9 is placed in the support 6 and can come into abutment at its end against the plate 7.
- the safety restraint device provided by the invention is thus retractable and automatic.
- the device with a single articulation axis culation considered does not react to a shock from the right in Figure 3, and this has two consequences: on the one hand, an obstacle so equipped can only be crossed in one direction; on the other hand, to equip the two chandeliers facing each other, you need a device that reacts to the left and a second device that reacts to the right, which means that you have to have both types of devices in store.
- the simple hinge of the first embodiment is replaced by a double hinge, folded in Z and comprising a lower horizontal plate 4, welded to the extension of the spindle 1, and which carries the axis 3 of a first hinge, the second plate 15 of which also belongs to a second hinge with an axis 13, parallel to the axis 3.
- This second hinge comprises an upper plate 16 which carries, at the same time, the U-shaped support 6 and the plate 7 of lateral support of the bar.
- the elastomer strap 18, placed as in the first mode between the support 6 and the plate 7, surrounds all of the three plates 4, 15 and 16 of the double hinge and the two axes 3 and 13 thereof, thus as the extension of pin 1.
- the device thus constituted therefore offers perfect security, whatever its mode of use.
- the U-shaped support 6 can have a shape different from a semicircle. It could only extend over a third of a circle, as in the case of FIGS. 7 to 9, or even be constituted by two parallel branches joined by a common perpendicular.
- the retaining device instead of being made of metal could be made of wood or rigid plastic.
- the lower spindle 1 could be replaced by a fork horizontally enclosing the candlestick.
- the U-shaped support can be articulated on a tenon of square or rectangular section intended to be engaged in a mortise among a set of such mortises staggered along a post or the like.
- the axis of articulation of the U-shaped support could also be carried by a collar surrounding the candlestick and engaged in notches thereof.
- the means used to bring the U-shaped support back into the service position could also be constituted by a helical spring arranged around the axis or also by two magnetized parts respectively secured to the plates of the hinge.

Description
La présente invention concerne un dispositif de retenue pour les barres d'obstacles, notamment du genre utilisé pour l'entraînement et la compétition en saut d'obstacles des chevaux.The present invention relates to a retaining device for obstacle bars, in particular of the kind used for training and competition in show jumping of horses.
On sait que de tels obstacles sont constitués par une barre mobile dont les extrémités reposent sur des arceaux qui sont solidaires d'une monture permettant de les placer à l'emplacement désiré de supports qui offrent des positions échelonnées pour ces montures. Par exemple, les supports sont constitués par des poteaux verticaux, souvent appelés chandeliers, et qui sont percés de trous échelonnés. Ces supports peuvent aussi être réalisés au moyen de barres horizontales ou obliques également percées de trous échelonnés.We know that such obstacles consist of a movable bar, the ends of which rest on arches which are integral with a frame making it possible to place them at the desired location of supports which offer staggered positions for these frames. For example, the supports consist of vertical posts, often called candlesticks, which are drilled with staggered holes. These supports can also be produced by means of horizontal or oblique bars also pierced with staggered holes.
De son côté, la monture peut être constituée par un taquet comportant une ou deux broches enfichables dans les trous du support. Cette monture peut également comporter un collier enserrant le poteau et qui est retenu dans des crans échelonnés placés aux arêtes de celui-ci.For its part, the frame can be constituted by a cleat comprising one or two pins pluggable into the holes of the support. This frame may also include a collar enclosing the post and which is retained in staggered notches placed at the edges thereof.
Dans l'état actuel de la technique, l'arceau précité a souvent la forme d'un quart de cercle et il est solidaire d'une partie de la monture située en regard du poteau opposé, de façon que le plan de cet arceau soit vertical et parallèle au plan de symétrie de l'obstacle.In the current state of the art, the aforementioned arch is often in the form of a quarter of a circle and it is integral with a part of the frame situated opposite the opposite post, so that the plane of this arch is vertical and parallel to the plane of symmetry of the obstacle.
Le dispositif ainsi réalisé présente des inconvénients, et même des dangers, pour les raisons suivantes:
- . la barre repose en simple appui sur le fond de l'arceau dont les bouts incurvés vers le haut empêchent sa chute. Elle ne peut tomber qu'après avoir été soulevée au-dessus de l'un ou l'autre de ces bouts. Ce soulèvement peut être normalement causé par le choc d'un membre antérieur du cheval en mouvement ascendant pour franchir l'obstacle. Dans ce cas, la barre, avant de tomber, va gêner davantage encore le cheval et pourra provoquer sa chute. Mais le danger s'accroît lorsque le cheval touche la barre avec un membre antérieur ou postérieur dans des conditions telles que le choc développe sur la barre une force dirigée vers le bas. Dans ce cas, la barre ne peut d'elle-même échapper aux arceaux qui la supportent, sauf si ellé casse ou rebondit. Le choc du cheval sur la barre risque dans tous les cas de le déséquilibrer complètement en provoquant des chutes dangereuses. En particulier, on constate que ces chutes provoquent fréquemment une fracture de la troisième phalange du cheval et de toute façon le rendent rétif. De plus, le remplacement des barres cassées est onéreux.
- . the bar rests by simply pressing on the bottom of the hoop, the upward curved ends of which prevent it from falling. It can only fall after being lifted over either end. This lifting can be normally caused by the shock of an anterior limb of the horse in upward movement to cross the obstacle. In this case, the bar, before falling, will further hamper the horse and may cause it to fall. But the danger increases when the horse touches the bar with a foreleg or hind limb in conditions such as shock develops downward force on the bar. In this case, the bar cannot of itself escape the arches which support it, unless it breaks or bounces. The impact of the horse on the bar risks in any case to completely unbalance it by causing dangerous falls. In particular, it is found that these falls frequently cause a fracture of the third phalanx of the horse and in any case make it restive. In addition, replacing broken bars is expensive.
On essaie parfois de pallier ces défauts en aplatissant l'arceau pour pouvoir placer la barre très près d'un bout et à la limite d'équilibre, et pour éviter qu'elle ne tombe intempestivement, on est conduit à l'appuyer contre les faces internes des chandeliers, ce qui peut entraîner son coincement avec les conséquences dangereuses bien connues.We sometimes try to overcome these faults by flattening the arch to be able to place the bar very close to one end and at the equilibrium limit, and to prevent it from accidentally falling, we are forced to press it against the internal faces of the candlesticks, which can lead to its jamming with the well-known dangerous consequences.
Mais un autre inconvénient, moins grave d'ailleurs, se présente : la hauteur de la barre n'est pas exactement fixée, et peut varier lorsqu'on la remet en place après qu'elle soit tombée. La régularité des épreuves de concours de saut en est affectée.But another disadvantage, less serious besides, presents itself: the height of the bar is not exactly fixed, and can vary when it is put back in place after it has fallen. The regularity of the jumping competition tests is affected.
La présente invention vise à éviter ces dangers et inconvénients et à assurer tant la chute de la barre, dès qu'elle est frappée, que la précision de sa mise en place.The present invention aims to avoid these dangers and disadvantages and to ensure both the fall of the bar, as soon as it is struck, and the precision of its positioning.
Suivant l'invention, le dispositif de retenue pour barre d'obstacle comprenant une monture destinée à être fixée en un emplacement réglable d'un chandelier ou analogue, cette monture portant une pièce en U servant de support pour la barre, est caractérisé en ce que ledit support peut pivoter autour d'au moins un axe de la monture parallèle à la barre lorsque celle-ci est en position de service dans les supports.According to the invention, the obstacle bar retainer comprising a frame intended to be fixed in an adjustable location of a candlestick or the like, this frame carrying a U-shaped piece serving as a support for the bar, is characterized in that that said support can pivot around at least one axis of the frame parallel to the bar when the latter is in the service position in the supports.
Ainsi, dès que la barre reçoit une poussée, elle vient appuyer contre un bord du support en U qui bascule aussitôt et libère entièrement la barre sans soulèvement de celle-ci. L'invention permet ainsi de réaliser un support de barre escamotable de sécurité.Thus, as soon as the bar receives a push, it comes to press against an edge of the U-shaped support which rocks immediately and releases the bar entirely without lifting it. The invention thus makes it possible to produce a retractable safety bar support.
De préférence, le dispositif selon l'invention comporte encore des moyens tendant à rappeler le support en U de la barre vers sa position de service normal, c'est-à-dire correspondant à la retenue de la barre. Ces moyens de rappel peuvent être, notamment, de nature élastique.Preferably, the device according to the invention also comprises means tending to return the U-shaped support of the bar to its normal operating position, that is to say corresponding to the retention of the bar. These return means can be, in particular, of an elastic nature.
e Ainsi, le support de la barre présente une position de service normal bien définie, et il en va de même pour la hauteur de la barre. De plus, en cas de pivotement sous l'effet d'un choc, il peut être ramené automatiquement vers cette position de service normal.e Thus, the bar support has a well-defined normal service position, and the same goes for the bar height. In addition, in the event of pivoting under the effect of an impact, it can be automatically brought back to this normal operating position.
Selon un premier mode de réalisation, le support en U de la barre est fixé à l'une des plaques d'une charnière simple dont l'axe est parallèle à la broche d'un taquet, destinée à être enfichée dans un trou d'un chandelier ou analogue, l'autre plaque étant solidaire de cette broche et servant de butée pour le support de la barre en position de service normal.According to a first embodiment, the U-shaped support of the bar is fixed to one of the plates of a simple hinge whose axis is parallel to the pin of a cleat, intended to be inserted in a hole a candlestick or the like, the other plate being integral with this pin and serving as a stop for the support of the bar in the normal service position.
Au repos, la charnière est fermée et ses deux plaques sont appuyées l'une contre l'autre. th choc transversal fait s'incliner la plaque supérieure à laquelle est fixé le support en U, qui laisse ainsi échapper la barre. Ce mode de réalisation est simple et économique, mais il ne concerne que les obstacles qui doivent être toujours franchis dans le même sens pendant un parcours.At rest, the hinge is closed and its two plates are pressed against each other. th transverse impact causes the upper plate to which the U-shaped support is inclined, which lets the bar escape. This embodiment is simple and economical, but it only concerns obstacles which must always be crossed in the same direction during a journey.
Suivant un deuxième mode de réalisation, perfectionné, la charnière simple est remplacée par une charnière double et le support en U de la barre est fixé à la première des plaques de la charnière dont les axes sont parallèles à la broche d'un taquet, la deuxième plaque reliant les deux axes et la troisième plaque étant solidaire de cette broche, et servant de butée pour le support de la barre, en position de service normal.According to a second embodiment, improved, the simple hinge is replaced by a double hinge and the U-shaped support of the bar is fixed to the first of the hinge plates whose axes are parallel to the pin of a cleat, the second plate connecting the two axes and the third plate being integral with this pin, and serving as a stop for the support of the bar, in the normal service position.
Au repos, les trois plaques sont empilées l'une sur l'autre, et la plaque supérieure portant le support en U peut basculer à droite ou à gauche. Ce mode de réalisation permet le franchissement bilatéral des obstacles.At rest, the three plates are stacked one on the other, and the upper plate carrying the U-shaped support can tilt to the right or to the left. This embodiment allows the bilateral crossing of obstacles.
Selon une version préférée de l'invention, utilisable notamment avec les deux modes précités de réalisation, le dispositif de retenue comprend une plaquette d'appui latéral pour la barre, parallèle au support en U, solidaire de celui-ci, et disposée entre ledit support et le taquet.According to a preferred version of the invention, usable in particular with the two aforementioned embodiments, the retaining device comprises a lateral support plate for the bar, parallel to the U-shaped support, integral with the latter, and disposed between said support and cleat.
Si les deux chandeliers ou analogues placés de part et d'autre de la barre sont équipés chacun d'un tel dispositif, la barre est contenue dans l'intervalle entre les deux plaquettes d'appui latéral, et comme ces plaquettes sont solidaires des supports en U et basculent avec ceux-ci, tout coincement de la barre contre les chandeliers est rendu impossible.If the two candlesticks or the like placed on either side of the bar are each equipped with such a device, the bar is contained in the interval between the two lateral support plates, and as these plates are integral with the supports U-shaped and tilt with them, any wedging of the bar against the candlesticks is made impossible.
Selon une autre particularité avantageuse de l'invention, le support en U de la barre s'étend sensiblement sur un demi-cercle.According to another advantageous feature of the invention, the U-shaped support of the bar extends substantially over a semicircle.
Une telle extension, impossible avec la technique actuelle en raison du soulèvement excessif de la barre qu'elle impliquerait, est au contraire recommandée dans le cadre de l'invention parce que la barre est ainsi mieux maintenue et sa position et sa hauteur sont mieux définies.On the contrary, such an extension, impossible with the current technique due to the excessive lifting of the bar which it would imply, is recommended within the framework of the invention because the bar is thus better maintained and its position and its height are better defined. .
D'autres particularités et avantages de l'invention apparaîtront encore dans la description qui va suivre.Other features and advantages of the invention will become apparent in the description which follows.

Dans le premier mode de réalisation de l'invention, décrit en référence aux Figures 1 à 4, le dispositif de retenue est du genre dans lequel la monture comprend un taquet métallique constitué par une broche rectiligne 1 avec son prolongement 1a, et par une broche 2 parallèle à la précédente, coudée à angle droit dans sa partie 2a soudée sur la broche 1. Un support 6 en forme de U est placé à l'avant du taquet, son plan médian est vertical en position de service normal, et perpendiculaire au plan des broches 1 et 2, également vertical et formant plan de symétrie du support 6.In the first embodiment of the invention, described with reference to Figures 1 to 4, the retaining device is of the type in which the frame comprises a metal cleat constituted by a straight pin 1 with its
Conformément à l'invention, le support en U 6, qui se développe sensiblement sur un demi-cercle, est soudé sur la plaque supérieure 5 d'une charnière simple dont l'axe 3 parallèle à la broche 1 se termine à l'avant par une tête 3a, et à l'arrière par une collerette tronconique 3b, obtenue par exemple par matage. La plaque inférieure 4 de la charnière est soudée sur le prolongement la de la broche 1 et sert de butée pour la plaque 5 en position de service normal. Une plaquette verticale 7, servant d'appui latéral à la barre d'obstacle, est soudée sur la plaque supérieure 5 de la charnière, parallèlement au support en U 6. Un bracelet en élastomère, placé entre le support en U 6 et la plaquette 7, entoure les deux plaques 4 et 5 et l'axe 3 de la charnière, en passant dans le prolongement la de la broche 1. En service, les broches 1 et 2 sont enfilées dans les trous échelonnés 10 d'un chandelier 21, ou autre (Figure 5), et la barre d'obstacle 9 est placée dans le support 6 et peut venir en butée par son extrémité contre la plaquette 7.In accordance with the invention, the U 6 support, which develops substantially on a semicircle, is welded to the
Le fonctionnement de ce dispositif et ses avantages sur la technique connue apparaissent clairement par la Figure 6 : si la barre 9 reçoit, d'un cheval franchissant l'obstacle, un choc suivant F venant de la gauche, le support en U 6 pivote suivant G autour de l'axe 3 de la charnière et laisse échapper immédiatement la barre 9. Le bracelet 8 en élastomère est mis en extension par l'écartement des plaques 4 et 5 et rappelle, vers la position de service normal, tout le dispositif dès la chute de la barre 9. Comme la plaquette 7 d'appui latéral pour la barre 9 bascule avec le support en U 6, tout frottement de la barre 9 contre la partie coudée 2a de la broche 2, et a fortiori contre le chandelier 21, est rendu impossible.The operation of this device and its advantages over the known technique are clearly shown in Figure 6: if the
Le dispositif de retenue de sécurité prévu par l'invention est ainsi escamotable et automatique.The safety restraint device provided by the invention is thus retractable and automatic.
Par contre, le dispositif à un seul axe d'articulation considéré, ne réagit pas à un choc venant de la droite de la Figure 3, et cela entraine deux conséquences : d'une part, un obstacle ainsi équipé ne peut être franchi que dans un sens ; d'autre part, pour équiper les deux chandeliers qui se font face, il faut un dispositif réagissant à gauche et un second dispositif réagissant à droite, ce qui oblige à avoir en magasin les deux types de dispositifs.On the other hand, the device with a single articulation axis culation considered, does not react to a shock from the right in Figure 3, and this has two consequences: on the one hand, an obstacle so equipped can only be crossed in one direction; on the other hand, to equip the two chandeliers facing each other, you need a device that reacts to the left and a second device that reacts to the right, which means that you have to have both types of devices in store.
Avec le second mode, préféré, de réalisation illustré par les Figures 7 à 9, ces sujétions sont éliminées. Dans cette réalisation, la charnière simple du premier mode de réalisation est remplacée par une charnière double, repliée en Z et comprenant une plaque horizontale inférieure 4, soudée au prolongement la de la broche 1, et qui porte l'axe 3 d'une première charnière dont la seconde plaque 15 appartient aussi à une seconde charnière d'axe 13, parallèle à l'axe 3. Cette seconde charnière comporte une plaque supérieure 16 qui porte, à la fois, le support en U 6 et la plaquette 7 d'appui latéral de la barre. Le bracelet 18 en élastomère, placé comme dans le premier mode entre le support 6 et la plaquette 7, entoure l'ensemble des trois plaques 4, 15 et 16 de la charnière double et les deux axes 3 et 13 de celle-ci, ainsi que le prolongement la de la broche 1.With the second, preferred, embodiment illustrated in Figures 7 to 9, these constraints are eliminated. In this embodiment, the simple hinge of the first embodiment is replaced by a double hinge, folded in Z and comprising a lower
Comme on le voit sur les Figures 8 et 9, le dispositif de retenue à double articulation ainsi réalisé, peut pivoter aussi bien si le choc sur la barre 9 vient de la gauche (Figure 8) que s'il vient de la droite (Figure 9). Dans les deux cas, dès que la barre 9 s'est échappée, le bracelet élastique 18 ramène l'ensemble de la double charnière en position de service normal (Figure 7), dans laquelle la barre peut être remise en place.As seen in Figures 8 and 9, the double hinge restraint thus produced, can pivot as well if the impact on the
Le dispositif ainsi constitué offre donc une parfaite sécurité, quel que soit son mode d'utilisation.The device thus constituted therefore offers perfect security, whatever its mode of use.
Bien entendu, l'invention r,e se limite pas aux deux modes de réalisation donnés à titre d'exemples, et on peut y apporter des variantes de formes et d'exécution.Of course, the invention r, e is not limited to two embodiments given by way of examples, and it is possible to bring to it variants of forms and execution.
Ainsi, le support en U 6 peut présenter une forme différente d'un demi-cercle. Il pourrait ne s'étendre que sur un tiers de cercle, comme dans le cas des Figures 7 à 9, ou encore être constitué par deux branches parallèles réunies par une perpendiculaire commune.Thus, the
De même, le dispositif de retenue au lieu d'être en métal pourrait être réalisé en bois ou en matière plastique rigide.Similarly, the retaining device instead of being made of metal could be made of wood or rigid plastic.
D'autres modes de fixation que le système à deux broches peuvent être prévus pour fixer le dispositif de retenue au chandelier. Par exemple, la broche inférieure 1 pourrait être remplacée par une fourche enserrant horizontalement le chandelier. De même, le support en U peut être articulé sur un tenon de section carrée ou rec- tangulaire destiné à être engagé dans une mortaise parmi un ensemble de telles mortaises échelonnées le long d'un poteau ou analogue. L'axe d'articulation du support en U pourrait encore être porté par un collier entourant le chandelier et engagé dans des crans de celui-ci.Other fixing methods than the two-pin system can be provided for fixing the retainer to the candlestick. For example, the lower spindle 1 could be replaced by a fork horizontally enclosing the candlestick. Likewise, the U-shaped support can be articulated on a tenon of square or rectangular section intended to be engaged in a mortise among a set of such mortises staggered along a post or the like. The axis of articulation of the U-shaped support could also be carried by a collar surrounding the candlestick and engaged in notches thereof.
Enfin, les moyens servant à ramener le support en U, en position de service, pourraient aussi être constitués par un ressort hélicoïdal disposé autour de l'axe ou encore par deux pièces aimantées respectivement solidaires des plaques de la charnière.Finally, the means used to bring the U-shaped support back into the service position could also be constituted by a helical spring arranged around the axis or also by two magnetized parts respectively secured to the plates of the hinge.
En conclusion, on mentionnera encore les avantages suivants de l'invention :
- . En cas de chute de la barre, celle-ci ne tombe pas loin, quelles que soient la direction et la force de la poussée, en raison du mouvement de rotation autour de la charnière et du caractère enveloppant du support en U.
- . Dans tous les cas, l'énergie cinétique du choc n'est jamais transmise aux chandeliers qui ne tombent plus.
- • Le dispositif de retenue réagit toujours de la même façon pour la même intensité et la même direction du choc sur la barre.
- . Si le choc sur la barre est faible, celle-ci ne tombe plus et est ramenée automatiquement en place.
- . If the bar falls, it does not fall far, whatever the direction and force of the push, due to the rotational movement around the hinge and the enveloping nature of the U-shaped support.
- . In all cases, the kinetic energy of the shock is never transmitted to candlesticks that no longer fall.
- • The restraint always reacts in the same way for the same intensity and the same direction of impact on the bar.
- . If the impact on the bar is weak, it no longer falls and is automatically brought back into place.
