Tel qu'il est représenté à la figure 1, ce dispositif 1 comprend
essentiellement un corps tubulaire 2 dont l'extrémité inférieure est pourvue de deux
cales repose-pied 3, 4 et dans le prolongement de laquelle une tige d'impact 5 est
apte à se déployer vers le bas.As shown in FIG. 1, this device 1 comprises

corps tubulaire 2 comporte dans sa partie inférieure un patin 51 fait en un matériau à
faible coefficient de frottement.This
Un fourreau 6 est fixé au corps tubulaire 2 à l'extrémité
supérieure de celui-ci. Ce fourreau 6 comprend un embout 61 dans lequel vient se
loger une potence 7 du type de celle utilisée pour équiper les bicyclettes désignées
sous l'appellation "VTT".A
Un guidon 8 muni de deux poignées 81, 82 est fixé à ladite
potence 7 de telle sorte qu'il s'étende transversalement au corps tubulaire 2.A
Une manette 83, 84 est montée, d'une manière connue en soi,
sur chaque poignée 81, 82. Sur chaque manette 83, 84 est fixé un câble 85, 86 muni
d'une gaine et relié aux moyens de freinage 9, décrits ci-après en détail.A

Le corps tubulaire 2 comporte à chacune de ses extrémités un
taraudage 21, 22.The
La tige d'impact 5 est creuse et comporte à son extrémité
supérieure une bague métallique 10 montée en force. Cette bague métallique 10
vient s'appuyer contre la partie inférieure d'un ressort hélicoïdal 11. Ce ressort 11 de
compression est adapté pour ramener la tige d'impact 5 vers une position extrême
déployée. En outre, les grandeurs caractéristiques de ce ressort 11 ont été
déterminées pour éviter tout contact entre la partie inférieure des cales repose-pied
3, 4 et le patin 51, même dans des conditions extrêmes d'utilisation. Il est à noter
que ce ressort 11 est interchangeable en fonction du poids de l'utilisateur.The
Les cales repose-pied 3, 4 sont perforées et chacune munies
sur leur face supérieure de crampons 31, 41. Ces cales 3, 4 sont réalisées en une
seule pièce usinée 12 réalisée en un matériau léger tel que l'aluminium. Cette pièce
usinée 12 est pourvue d'un passage axial 121 adapté pour recevoir par coulissement
la tige d'impact 5, et est vissée à l'extrémité inférieure du corps tubulaire 2.The

au moyen de vis 15.This ball bushing 13 is held in place in its
housing through an
Le fourreau 6 comprend, à son extrémité inférieure, un
renflement 63 adapté pour loger un manchon 91 cylindrique qui constitue une partie
des moyens de freinage 9 conformes à l'invention (figure 2a).The
Le manchon 91 comporte, dans sa partie inférieure, des pattes
911 présentant chacune un pan incliné 912 disposées de manière concentrique, de
sorte qu'elles forment une cavité 913 présentant une symétrie de révolution d'axe
confondu avec l'axe A-A de coulissement de la tige d'impact 5. Un anneau
cylindrique en élastomère 92 est monté en force autour de pattes 911 et constitue la
garniture de frein selon l'invention.The
Les moyens de freinage 9 comportent également un pointeau
93 percé d'un canal 931 dans lequel viennent se loger les câbles.The braking means 9 also comprise a
La tête conique 932 de ce pointeau 93 est logée dans la cavité
913 formée par les pattes 911 en venant en butée contre les pans inclinés 912. Le
pointeau 93 comprend, à l'extrémité opposée de la tête 932, un filetage 933 dans
lequel est vissé un système d'écrou-contre-écrou moleté 94.The
Ce système d'écrou-contre-écrou 94 permet de maintenir en
place un ressort de compression 95 dont l'extrémité supérieure vient s'appuyer sur
une rondelle 96. La rondelle 96 vient elle-même s'appuyer sur la face inférieure de
l'anneau cylindrique 92.This nut-against-

Le fonctionnement des moyens de freinage conformes à l'invention est expliqué ci-après. The operation of the braking means according to the invention is explained below.
Lorsque l'utilisateur désire s'immobiliser ou diminuer
l'amplitude des bonds réalisés, il appuie sur les manettes 83, 84 et provoque ainsi la
tension des câbles 85, 86 en amenant le serre câbles 97 en butée contre le système
d'écrou-contre-écrou moleté 94 (figure 2b).When the user wants to stop or decrease
the amplitude of the hops made, he presses the
Cette tension des câbles 85, 86 provoque le déplacement du
pointeau 93 vers l'intérieur de la cavité 913 avec frottement de la tête conique 932
contre les pans inclinés 912 et la compression du ressort 95 contre la rondelle 96.This tension of the

des pattes 911.The displacement of the
L'anneau 92 est alors déformé radialement (figure 2b) et sa
paroi latérale 921 extérieure vient frotter contre la paroi interne 52 de la tige
d'impact 5, ce qui provoque le freinage de cette dernière par rapport au corps
tubulaire 2.The
Une fois que le freinage a été réalisé, l'utilisateur relâche les
manettes 83, 84, et met ainsi les câbles hors tension.Once the braking has been completed, the user releases the

ainsi le pointeau 93 dans la position qu'il occupait initialement avant le freinage.The compression spring 95 returns to the free state and brings back
thus the
Dans le même temps, les pattes 911 se rapprochent les unes
des autres et l'anneau 92 revient à l'état non déformé.At the same time, the

redevient possible.The sliding of the

d'impact 5.Figure 3 is a sectional view of a variant of the
Selon cette variante, la tige d'impact 5 se compose de deux
parties 5a, 5b liées entre elles au moyen d'une tige filetée 52 qui sert également à
maintenir le patin 5.According to this variant, the
La plus petite partie 5b de la tige d'impact agencée dans la
partie basse de la tige peut être remplacée par toute autre partie de forme identique
et de longueur différente. La longueur de cette partie 5b est ajustable en fonction de
la taille de l'utilisateur.The
Bien entendu, il va de soi que de nombreuses modifications peuvent être apportées sans pour autant sortir du cadre de l'invention. Of course, it goes without saying that many changes can be made without departing from the scope of the invention.
Ainsi, la structure particulière des moyens de freinage 9
décrite ci-dessus peut tout à fait être remplacée par une structure équivalente, telle
que des mâchoires avec mors adaptés pour serrer une ou plusieurs gamiture(s) de
frein disposée(s) de manière concentrique à l'extérieur de la tige d'impact 5.Thus, the particular structure of the braking means 9
described above can be replaced by an equivalent structure, such as
jaws with jaws suitable for squeezing one or more padding (s)
brake arranged concentrically outside the
De même, le ressort de compression de la variante préférée permettant de rappeler la tige d'impact peut être agencé d'une manière différente, comme par exemple être disposé autour de la tige d'impact sous les cales repose-pied. Il peut également être progressif, ce qui permet de réaliser les premiers sauts plus facilement. Il peut également être remplacé par tout autre moyen équivalent adapté pour ramener la tige d'impact dans sa position extrême déployée tel que des moyens pneumatiques.Similarly, the compression spring of the preferred variant to recall the impact rod can be arranged in a different way, as for example be arranged around the impact rod under the footrest wedges. It can also be progressive, which allows to make the first jumps easier. It may also be replaced by any other equivalent means adapted to return the impact rod to its extended deployed position such as pneumatic means.
