L'invention se rapporte à un système de fixation de prise d'escalade, à une prise d'escalade comprenant un tel système et à un mur d'escalade comprenant une telle prise. The invention relates to a climbing hold fixing system, a climbing hold comprising such a system and a climbing wall comprising such a catch.
L'invention s'applique à la réalisation de murs d'escalade artificiels dans lesquels des prises d'escalade comprenant chacune un corps conformé pour constituer un appui pour la main ou le pied d'un utilisateur sont disposés sur une paroi pour former des voies permettant à l'utilisateur de s'exercer à l'escalade. The invention applies to the realization of artificial climbing walls in which climbing holds each comprising a body shaped to form a support for the hand or foot of a user are arranged on a wall to form lanes allowing the user to practice climbing.
Un système de fixation de prise d'escalade comprend généralement un insert fixé à la paroi du mur d'escalade et comportant une ouverture, un support destiné à être incorporé dans le corps de la prise d'escalade et une tige de fixation du support à l'insert. A climbing hold fixing system generally comprises an insert attached to the wall of the climbing wall and having an opening, a support for incorporation into the body of the climbing jack and a rod for attaching the support to the insert.

In the embodiment shown, the guide ramp 15 is made in two parts, one of which is constituted by the engagement portion 15a, separated by an intermediate bearing 15b substantially parallel to the rear surface 6b of the plate 6. Each Seat 16 comprises a bearing 16a substantially parallel to the rear surface 6b of the plate 6 and an abutment surface 16b, radial with respect to the axis A of the opening 7. In a variant, the bearing 16a of each seat 16 could be curved towards the rear surface 6b of the plate 6.
Sur les figures 1 et 3, le support 20 est réalisé sous la forme d'un manchon cylindrique de section circulaire selon un axe B. Le support 20 comporte un alésage 21 traversant s'étendant selon un axe, coaxial à l'axe B du support 20, entre une surface avant 20a et une surface arrière 20b opposé à la surface avant 20a et destinée à être placée en contact avec la surface avant 6a de la plaque 6. L'alésage 21 est pourvu d'un épaulement 22 annulaire, s'étendant radialement par rapport à l'axe de l'alésage 21 . La surface arrière 20b du support 20 comprend des crans 23 agencés pour pouvoir venir en prise avec les crans 1 1 de la surface avant 6a de la plaque 6 lorsque la surface arrière 20b du support 20 et la surface avant 6a de la plaque 6 sont en contact. In FIGS. 1 and 3, the support 20 is made in the form of a cylindrical sleeve of circular section along an axis B. The support 20 comprises a through bore 21 extending along an axis, coaxial with the axis B of the support 20, between a front surface 20a and a rear surface 20b opposite the front surface 20a and intended to be placed in contact with the front surface 6a of the plate 6. The bore 21 is provided with an annular shoulder 22, extending radially with respect to the axis of the bore 21. The rear surface 20b of the support 20 comprises notches 23 arranged to be able to engage with the notches 11 of the front surface 6a of the plate 6 when the rear surface 20b of the support 20 and the front surface 6a of the plate 6 are in contact with each other. contact.
La tige de fixation 25 présente un axe C et comporte un corps 26 cylindrique de section circulaire selon l'axe C de la tige de fixation 25, s'étendant depuis une première extrémité 25a pourvue d'une tête 27 jusqu'à une deuxième extrémité 25b. La tête 27 est tronconique et présente une surface d'appui 28 latérale s'écartant de l'axe C de la tige de fixation 25. La tête 27 comporte en outre, sur une surface supérieure, un évidement 29
conformé pour coopérer avec outil afin de pouvoir faire tourner la tige de fixation 25, comme il apparaîtra de la suite de la description. En variante, la tête 27 pourrait être cylindrique, la surface d'appui 28 étant radiale par rapport à l'axe C de la tige de fixation 25. La deuxième extrémité 25b de la tige de fixation 25 comporte deux plots 30 écartés l'un de l'autre, saillant depuis le corps 26 radialement par rapport à l'axe C de la tige de fixation 25. Les plots 30 sont diamétralement opposés et agencés à la même distance de la première extrémité 25a. Ils présentent chacun une surface latérale 30a, par exemple cylindrique de section circulaire, radiale par rapport à l'axe C de la tige de fixation 25 et dont une partie est orientée vers la première extrémité 25a. The fixing rod 25 has a C axis and comprises a cylindrical body 26 of circular section along the axis C of the fixing rod 25, extending from a first end 25a provided with a head 27 to a second end 25b. The head 27 is frustoconical and has a lateral bearing surface 28 away from the axis C of the fixing rod 25. The head 27 further comprises, on an upper surface, a recess 29. shaped to cooperate with tool in order to rotate the fastening rod 25, as will be apparent from the following description. As a variant, the head 27 could be cylindrical, the bearing surface 28 being radial with respect to the axis C of the fastening rod 25. The second end 25b of the fastening rod 25 comprises two studs 30 spaced apart. on the other, protruding from the body 26 radially relative to the axis C of the fixing rod 25. The studs 30 are diametrically opposed and arranged at the same distance from the first end 25a. They each have a lateral surface 30a, for example cylindrical of circular section, radial with respect to the axis C of the fixing rod 25 and a part of which is oriented towards the first end 25a.
Comme représenté sur les figures 3 à 5, la deuxième extrémité 25b de la tige de fixation 25 et l'ouverture 7 de l'insert 5 sont conformées pour former une fixation du type « à baïonnette » dans laquelle la deuxième extrémité 25b peut passer au travers de l'ouverture 7 dans une première position angulaire de la tige de fixation 25 par rapport à l'insert 5, et dans laquelle la deuxième extrémité 25b ne peut pas passer au travers de l'ouverture 7 dans une deuxième position angulaire de la tige de fixation 25 par rapport à l'insert 5, de manière à pouvoir retenir la tige de fixation 25 sur l'insert 5 dans la deuxième position angulaire. As shown in FIGS. 3 to 5, the second end 25b of the fixing rod 25 and the opening 7 of the insert 5 are shaped to form a "bayonet-type" fastener in which the second end 25b can move to through the opening 7 in a first angular position of the fixing rod 25 relative to the insert 5, and wherein the second end 25b can not pass through the opening 7 in a second angular position of the fixing rod 25 relative to the insert 5, so as to be able to retain the fastening rod 25 on the insert 5 in the second angular position.
En particulier, comme représenté sur la figure 3, pour réaliser la fixation du support 20 à l'insert 5, la tige de fixation 25 est d'abord placée coaxialement dans l'alésage 21 du support 20 de telle manière que la surface d'appui 28 de la tige de fixation 25 vienne en appui sur l'épaulement 22 du support 20. Un organe déformable élastiquement 35, réalisé dans le mode de réalisation représenté sous la forme d'un empilement de rondelles Belleville, est interposé entre la surface d'appui 28 de la tige de fixation 25 et l'épaulement 22 du support 20. Par ailleurs, une entretoise 36 est disposée entre l'épaulement 22 du support 20 et la surface avant 6a de la plaque 6 de l'insert 5, entre les arcs de crans 1 1 . In particular, as shown in FIG. 3, in order to fix the support 20 to the insert 5, the fixing rod 25 is first placed coaxially in the bore 21 of the support 20 so that the surface support 28 of the fixing rod 25 comes to bear on the shoulder 22 of the support 20. An elastically deformable member 35, made in the embodiment shown in the form of a stack of Belleville washers, is interposed between the surface of the 28 support of the fixing rod 25 and the shoulder 22 of the support 20. In addition, a spacer 36 is disposed between the shoulder 22 of the support 20 and the front surface 6a of the plate 6 of the insert 5, between the notches 1 1.
Ensuite, comme représenté sur les figures 3 et 4, la tige de fixation 20 est positionnée coaxialement à l'ouverture 7 dans la première position angulaire de manière à pouvoir insérer le corps 26 et les plots 30 de la tige de fixation 25 respectivement dans le trou 8 et les encoches 9 de l'ouverture 7 de l'insert 5 dont les dimensions et la géométrie sont adaptées en conséquence. Au fur et à mesure que le corps 26 pénètre le trou 8, les plots 30 s'engagent dans les fentes 14 de la jupe 12. Then, as shown in FIGS. 3 and 4, the fastening rod 20 is positioned coaxially with the opening 7 in the first angular position so as to be able to insert the body 26 and the studs 30 of the fastening rod 25 respectively into the hole 8 and the notches 9 of the opening 7 of the insert 5 whose dimensions and geometry are adapted accordingly. As the body 26 enters the hole 8, the studs 30 engage in the slots 14 of the skirt 12.
Comme représenté sur la figure 5, le corps 26 de la tige de fixation 25 et le trou 8 de l'ouverture présentant une géométrie de révolution, la tige de fixation 25 peut être tournée autour de son axe C entre la première position angulaire et la deuxième position angulaire. Avantageusement, les sièges 16 sont positionnés par rapport aux encoches 9 de telle manière que la tige de fixation 25 puisse passer de la première position angulaire à la deuxième position angulaire par un déplacement angulaire inférieur à un tour (360°),
voire inférieur à un demi-tour (180°), de préférence voisin d'un quart de tour (90 °). La surface latérale 30a de chaque plot 30 peut alors s'engager sur la partie d'engagement 15a de l'une des rampes de guidage 15 et glisser le long de la rampe de guidage 15 jusqu'à atteindre le siège 16. Au cours de ce mouvement, les rondelles Belleville 35 sont comprimées pour mettre sous tension la tige de fixation 25 et assurer le maintien stable des plots 30 dans les sièges 16 de la jupe 12 de l'insert 5 (figure 6). As shown in FIG. 5, the body 26 of the fixing rod 25 and the hole 8 of the opening having a geometry of revolution, the fixing rod 25 can be rotated about its axis C between the first angular position and the second angular position. Advantageously, the seats 16 are positioned relative to the notches 9 so that the fixing rod 25 can pass from the first angular position to the second angular position by an angular displacement less than one turn (360 °), even less than half a turn (180 °), preferably close to a quarter turn (90 °). The lateral surface 30a of each stud 30 can then engage on the engagement portion 15a of one of the guide ramps 15 and slide along the guide ramp 15 to reach the seat 16. In the course of this movement, the Belleville washers 35 are compressed to tension the fixing rod 25 and ensure the stable maintenance of the pads 30 in the seats 16 of the skirt 12 of the insert 5 (Figure 6).
La tête 27 de la tige de fixation 25 se trouve ainsi solidarisée au support 20. Les parties des surfaces latérales 30a des plots 30 orientées vers la première extrémité 25a de la tige de fixation constituent des surfaces de blocage venant en butée contre la face arrière 5b de l'insert 5, au niveau des sièges 16, pour assurer le blocage de la tige de fixation 25 et la fixation du support 20 entre la surface d'appui 28 de la tige de fixation 25 et la surface avant 6a de l'insert 5. Les crans 1 1 , 23 de la surface arrière 20b du support 20 et de la surface avant 6a de l'insert 5 sont en prise pour permettre une indexation de la position relative du support 20 et de l'insert 5, et ainsi simplifier l'orientation de la prise d'escalade 40, et empêcher la rotation du support 20 par rapport à l'insert 5 lorsque le support 20 repose sur l'insert 5. The head 27 of the fastening rod 25 is thus secured to the support 20. The portions of the lateral surfaces 30a of the studs 30 oriented towards the first end 25a of the fastening rod constitute blocking surfaces abutting against the rear face 5b of the insert 5, at the seats 16, to ensure the locking of the fixing rod 25 and the attachment of the support 20 between the bearing surface 28 of the fixing rod 25 and the front surface 6a of the insert 5. The notches 11, 23 of the rear surface 20b of the support 20 and of the front surface 6a of the insert 5 are engaged to allow indexing of the relative position of the support 20 and the insert 5, and thus simplify the orientation of the climbing hold 40, and prevent the rotation of the support 20 relative to the insert 5 when the support 20 rests on the insert 5.
L'invention n'est pas limitée au mode de réalisation du système de blocage décrit précédemment et en particulier aux modes de réalisation des surfaces de blocage et de l'ouverture décrits précédemment. En variante, la tige de fixation 25 pourrait comprendre plus de deux surfaces de blocage 30a, avantageusement équiréparties autour de l'axe C de la tige de fixation 25, réalisées sur des plots 30 ou autre, l'ouverture 7 de l'insert 5 étant conformée en conséquence. The invention is not limited to the embodiment of the locking system described above and in particular to the embodiments of the locking surfaces and the opening described above. In a variant, the fixing rod 25 could comprise more than two locking surfaces 30a, advantageously evenly distributed around the axis C of the fixing rod 25, made on pads 30 or the like, the opening 7 of the insert 5 being consistent accordingly.
La figure 6 représente une prise d'escalade 40 dont le corps 41 est fixé à la paroi 51 du mur d'escalade 50 par l'intermédiaire du système de fixation 1 décrit précédemment. Figure 6 shows a climbing grip 40 whose body 41 is fixed to the wall 51 of the climbing wall 50 through the fastening system 1 described above.
En particulier, la paroi 51 présente une surface extérieure 51 a, par exemple imitant la surface d'une paroi rocheuse naturelle, et comporte une ou plusieurs cavités 52 borgnes présentant un fond 53. L'insert 5 est placé dans la cavité 52 avec la surface avant 6a de la plaque 6 affleurant sensiblement la surface extérieure 51 a de la paroi 51 et la surface arrière 6b de la plaque 6 et la jupe 12 placées en regard du fond 53 de la cavité 52. L'insert 5 peut alors être fixé à la paroi 51 , par exemple par vissage au travers des orifices 10 de la plaque 6. In particular, the wall 51 has an outer surface 51a, for example imitating the surface of a natural rock wall, and comprises one or more blind cavities 52 having a bottom 53. The insert 5 is placed in the cavity 52 with the front surface 6a of the plate 6 substantially flush with the outer surface 51a of the wall 51 and the rear surface 6b of the plate 6 and the skirt 12 placed opposite the bottom 53 of the cavity 52. The insert 5 can then be fixed at the wall 51, for example by screwing through the orifices 10 of the plate 6.
Le corps 41 , par exemple surmoulé sur le support 20, présente un trou traversant 42 en correspondance avec l'alésage 21 du support 20 permettant d'accéder à la tête 27 de la tige de fixation 25 afin de pouvoir la faire passer de la première position angulaire à la deuxième position angulaire et ainsi réaliser la fixation de la prise d'escalade 40 à la paroi 51 du mur d'escalade 50 comme décrit précédemment.
Les figures 7 et 8 représentent l'insert 5' et le support 20' d'une variante du système de fixation de prise d'escalade décrit précédemment. Dans cette variante, l'ouverture 7' de l'insert 5' comporte un taraudage qui se prolonge dans la jupe 12' de l'insert 5'. Le taraudage est adapté pour coopérer avec un filetage d'une tige de fixation filetée d'une prise d'escalade classique. Il est ainsi possible de monter sur les inserts d'un même mur d'escalade des prises d'escalade classiques, à tige de fixation filetée, et des prises d'escalade comprenant le système de fixation à baïonnette selon l'invention. The body 41, for example overmolded on the support 20, has a through hole 42 in correspondence with the bore 21 of the support 20 for accessing the head 27 of the fixing rod 25 in order to be able to pass it from the first angular position at the second angular position and thus achieve the fixing of the climbing jack 40 to the wall 51 of the climbing wall 50 as described above. Figures 7 and 8 show the insert 5 'and the support 20' of a variant of the climbing attachment fixing system described above. In this variant, the opening 7 'of the insert 5' has a tapping which extends into the skirt 12 'of the insert 5'. The tapping is adapted to cooperate with a thread of a threaded fastening rod of a conventional climbing jack. It is thus possible to mount on the inserts of the same climbing wall conventional climbing holds, with threaded fastening rod, and climbing holds including the bayonet fastening system according to the invention.
Sur les figures 7 et 8, la plaque 6' de l'insert 5' comprend une couronne centrale circulaire de crans 1 1 ' de forme globalement trapézoïdale. Les orifices 10', dont le nombre a été augmenté par rapport au mode de réalisation précédemment décrit, sont disposés de manière périphérique autour de la couronne de crans 1 1 '. En outre, la rampe de guidage 15' du bord libre 13' de la jupe 12' comprend une partie d'engagement, inclinée, amenant directement à un siège 16' en creux, incurvé vers la plaque 6' par rapport à une portion terminale de la partie d'engagement. In Figures 7 and 8, the plate 6 'of the insert 5' comprises a circular central ring of notches 1 1 'of generally trapezoidal shape. The orifices 10 ', the number of which has been increased relative to the embodiment previously described, are arranged peripherally around the ring gear 11'. In addition, the guide ramp 15 'of the free edge 13' of the skirt 12 'comprises an inclined engagement portion directly leading to a recessed seat 16' curved towards the plate 6 'with respect to a terminal portion of the commitment part.
Le support 20' comprend une couronne centrale circulaire de crans 23' de forme globalement trapézoïdale complémentaire des crans 1 1 ' de la couronne de l'insert 5'. Le support 20' a, par ailleurs, une surface extérieure présentant globalement une symétrie de révolution autour de l'axe B' avec un épaulement annulaire sensiblement médian entre une partie élargie au voisinage des crans 23' et une partie étroite. Des méplats sont ménagés dans la partie élargie. The support 20 'comprises a circular central ring of notches 23' of generally trapezoidal shape complementary to the notches 1 1 'of the crown of the insert 5'. The support 20 'has, moreover, an outer surface generally having a symmetry of revolution about the axis B' with a substantially median annular shoulder between an enlarged portion in the vicinity of the notches 23 'and a narrow portion. Flats are formed in the enlarged part.
Les autres composants du système de fixation, globalement inchangés par rapport à la description qui en a déjà été faire, ne sont pas décrits plus en détails et l'on se référera à la description ci-dessus pour plus de détails.
