Abstract
Description
L'invention concerne un dispositif de serrage par sangle dentée coopérant avec un organe de verrouillage à cliquet. Elle se rapporte plus particulièrement aux dispositifs de serrage pouvant équiper les fixations de surf de neige à sangles, les patins à roulette, patins en ligne, les chaussures de sport à tige souple ou semi-rigide telles que les bottes de surf de neige, les chaussures de randonnées, ou les chaussures de ski de fond, etc.The invention relates to a clamping device by toothed strap cooperating with a member. ratchet lock. It relates more particularly to clamping devices can be fitted to snowboard bindings with straps, roller skates, inline skates, sports shoes with flexible or semi-rigid upper such as snowboard boots, hiking boots, or cross-country ski boots, etc.
Dans les dispositifs du type énoncé, l'objectif est de pouvoir réaliser un serrage d'une bande ou d'un volet contre une surface généralement de forme courbe, en tissu ou autre matériau souple ; au moyen d'une sangle dentée qui s'engage par engrènement dans un cliquet solidaire de ladite bande ou dudit volet. Le desserrage de la bande ou du volet s'effectue par actionnement d'un levier qui libère la sangle dentée de la denture du cliquet.In devices of the stated type, the objective is to be able to tighten a strip or shutter against a generally curved, fabric or other surface flexible material; by means of a toothed strap which engages by engagement in a ratchet integral with said strip or said flap. The band or flap is loosened by actuation of a lever which releases the toothed strap from the teeth of the pawl.
Un exemple de dispositif est donné par le document AT-C-379297. Selon ce document, un dispositif de serrage comprend une sangle munie d'une portion dentée et une bande à serrer sur laquelle est monté un organe de verrouillage. Ce dernier comprend une embase fixée sur la bande et un cliquet relié à l'embase par deux articulations. La sangle s'engage entre le cliquet et l'embase pour permettre le serrage du dispositif.An example of a device is given by document AT-C-379297. According to this document, a tightening device comprises a strap provided with a toothed portion and a band to be tightened on which is mounted a locking member. The latter includes a base fixed to the band and a ratchet connected to the base by two joints. The strap engages between the pawl and the base to allow the tightening of the device.
Un inconvénient majeur des systèmes existants provient de ce qu'aucun n'apporte à la fois une sécurité de verrouillage suffisante et une libération rapide de la sangle en dehors de l'organe de verrouillage.A major drawback of existing systems is that none brings both sufficient locking security and rapid release of the strap outside the locking member.
En général, le couple exercé sur le levier est orienté dans la direction opposée au bout de la sangle dentée ce qui a tendance à favoriser l'engagement de la sangle dentée dans l'organe de verrouillage plutôt que son dégagement rapide et automatique.In general, the torque exerted on the lever is oriented in the opposite direction at the end of the toothed strap which tends to favor the engagement of the toothed strap in the locking rather than quick and automatic release.
Or, dans le cas d'une fixation de surf de neige ayant pour objet de retenir une botte souple sur une planche de glisse, par exemple, il est important de pouvoir rendre le desserrage des sangles plus rapide car cette opération se répète souvent lors de la pratique du surf et dans des conditions quelquefois difficiles.However, in the case of a snowboard binding intended to retain a flexible boot on a sliding board, for example, it is important to be able to make the loosening of the straps faster because this operation is often repeated when surfing and in sometimes difficult conditions.
Le but de la présente invention est donc d'apporter une solution satisfaisante aux problèmes rencontrés par les systèmes de l'art antérieur.The purpose of the present invention is therefore to provide a satisfactory solution to problems encountered by the systems of the prior art.
A cet effet, le dispositif de serrage de l'invention comprend une partie de sangle munie d'une portion dentée et un élément à serrer du type bande, volet ou rabat sur lequel est monté un organe de verrouillage comprenant :
- une embase fixée sur l'élément à serrer ;
- un cliquet relié à l'embase par une seule articulation et ayant au moins une portion dentée complémentaire de retenue destinée à coopérer avec la portion dentée de la partie de sangle ;
- un moyen de rappel élastique qui maintient les portions dentées en contact l'une de l'autre en position de verrouillage ;
- un levier solidaire du cliquet, le levier étant actionnable à l'encontre de la force exercée par le moyen de rappel élastique pour le désengagement des portions dentées,
- et un espace ménagé entre le cliquet et l'embase pour l'engagement de la partie de sangle sous la portion dentée du cliquet.
- a base fixed to the element to be clamped;
- a pawl connected to the base by a single articulation and having at least one complementary toothed retention portion intended to cooperate with the toothed portion of the strap part;
- elastic return means which keeps the toothed portions in contact with each other in the locked position;
- a lever secured to the pawl, the lever being actuable against the force exerted by the elastic return means for disengaging the toothed portions,
- and a space provided between the pawl and the base for the engagement of the strap part under the toothed portion of the pawl.
Le dispositif selon l'invention est caractérisé par le fait que l'espace est ménagé dans le cliquet entre l'articulation et la portion dentée pour le passage de la partie de sangle, et par le fait que la portion dentée et le levier sont situés par rapport à l'axe d'articulation d'un même côté d'engagement de la sangle.The device according to the invention is characterized in that the space is provided in the ratchet between the joint and the toothed portion for the passage of the strap portion, and by the fact that the toothed portion and the lever are located relative to the axis of articulation of the same strap engaging side.
Ainsi, en position de verrouillage, le couple de serrage qui s'exerce par le cliquet sur la portion dentée augmente proportionnellement à l'effort de traction exercée sur la sangle dans le sens du désengagement de l'organe de verrouillage. La conséquence est la garantie d'une sécurité du verrouillage quelque soient les efforts qui s'exercent sur le dispositif.Thus, in the locked position, the tightening torque exerted by the pawl on the toothed portion increases in proportion to the tensile force exerted on the strap in the direction of disengagement of the locking member. The consequence is the guarantee of a locking security whatever the forces exerted on the device.
De plus, le couple exercé manuellement sur le levier pour désengager les portions dentées entre elles, est dirigé dans une direction qui favorise la séparation de la bande ou volet par rapport à la sangle dentée. Il s'ensuit que la libération du dispositif est plus rapide et peut s'exercer d'une seule main par une simple action sur le levier.In addition, the torque exerted manually on the lever to disengage the toothed portions between them, is directed in a direction which promotes the separation of the strip or flap by compared to the toothed strap. It follows that the release of the device is faster and can exercise with one hand by a simple action on the lever.
La description suivante en référence aux dessins annexés permettra de mieux comprendre la présente invention.The following description with reference to the accompanying drawings will allow a better understanding the present invention.
La figure 1 est une vue générale en perspective de dispositifs de serrage de l'art antérieur adaptés sur une fixation à coque pour la pratique du surf de neige.Figure 1 is a general perspective view of clamping devices of the prior art suitable for a shell attachment for snowboarding.
La figure 2 est une vue en coupe latérale d'un dispositif d'un dispositif selon l'art antérieur.Figure 2 is a side sectional view of a device of a device according to the prior art.
La figure 3 est une vue similaire à la vue de la figure 2 pour un dispositif selon l'invention.Figure 3 is a view similar to the view of Figure 2 for a device according to the invention.
La figure 4 est vue en coupe partielle selon un plan décalé de celui de la figure 3 pour un dispositif selon l'invention.Figure 4 is a partial sectional view along a plane offset from that of Figure 3 for a device according to the invention.
Comme le montre la figure 1, les dispositifs dont il est question dans la présente demande trouvent leur utilité dans le domaine des fixations à coque de surf de neige dont un spécimen est représenté à titre d'exemple.As shown in Figure 1, the devices in question in the present application find their utility in the field of snowboard hull bindings including a specimen is shown as an example.
La fixation 1 comprend deux dispositifs de serrage séparés 10, 11 ; l'un d'eux 10 servant à
serrer le bout d'une chaussure (non représentée) et l'autre 11 servant à serrer la partie du coude-pied
de la chaussure. D'autre part, la fixation comprend une embase 12 sur laquelle est
destinée à reposer la semelle de la chaussure ; et qui se prolonge sur les côtés et vers le haut
par des bords latéraux 120, 121 et à l'arrière par un arceau rigide 122. Un élément d'appui
arrière 13 est articulé sur les bords 120, 121 et prend appui contre l'arceau 122 pour procurer
un support arrière nécessaire à la prise de virage sur la carre arrière de la planche notamment.The
Le dispositif de l'art antérieur 10, qui est illustré à titre d'exemple et en détail à la figure 2,
comprend une partie de sangle 2 munie d'une portion dentée 20 et d'une bande à serrer 3 sur
lequel est monté un organe de verrouillage 4. La partie de
sangle 2 est rattachée fixement à l'un des bords latéraux 120 de la fixation, tandis
que la bande 3 est rattachée fixement au bord opposé 121.The device of the
La bande comprend généralement une partie inextensible et flexible 30 en
plastique, tissu ou cuir et une partie de rembourrage 31 en tissu ou en mousse
pour assurer le confort lors du serrage.The strip generally comprises an inextensible and
La partie de sangle est réalisée en plastique semi-rigide de façon à présenter une certaine tenue en flexion tout en étant apte à se conformer à la forme bombée de la chaussure.The strap part is made of semi-rigid plastic so as to present a certain flexural strength while being able to conform to the domed shape of the shoe.
L'organe de verrouillage 4 est muni d'une embase 42 fixée sur le volet ou la
bande 3. Un cliquet 41 est relié à l'embase par une articulation 43 et comprend une
portion dentée complémentaire de retenue 410 destinée à coopérer avec la portion
dentée 20 de la partie de sangle 2. Un ressort de torsion 44 maintient les portions
dentées 20, 410 en contact l'une de l'autre en position de verrouillage. Enfin,
l'organe de verrouillage comprend un levier 45 qui est actionnable à l'encontre de
la force exercée par le ressort 44 pour le désengagement des portions dentées 20,
410.The locking member 4 is provided with a
L'engagement de la partie de sangle dentée 2 se fait dans le sens A indiqué
sans action manuelle du levier grâce notamment à l'orientation des dents qui
permet une rotation du cliquet et un soulèvement de la portion de dents 410.
Lorsque le serrage est suffisant, on stoppe l'engagement de la sangle dans une
position de verrouillage donnée et tout retour de la sangle dans le sens inverse de
A devient impossible sans action manuelle du cliquet.The engagement of the
La figure 2 montre donc l'opération manuelle de désengagement qui consiste à
agir sur le levier 45 dans le sens de rotation B indiqué ; ce qui éloigne les partie
dentées l'une de l'autre et permet le glissement de la sangle 2 hors de l'organe de
verrouillage. Comme il apparaít sur la figure 2, le couple exercé dans le sens B
indiqué favorise un rapprochement et un recouvrement de la bande rembourrée 3
et de la partie de sangle 2. En pratique, on s'aperçoit donc qu'il est difficile de
pratiquer au déchaussage par une simple action du levier et qu'il est nécessaire de
tirer la partie de sangle dentée hors de l'organe de verrouillage en utilisant l'autre
main.Figure 2 therefore shows the manual disengagement operation which consists of
act on
Les figures 3 et 4 montrent la solution qui est proposée par l'invention pour tenter de résoudre ce problème tout en conservant une sécurité de verrouillage du dispositif.Figures 3 and 4 show the solution which is proposed by the invention for attempt to resolve this issue while retaining lock security on the device.
Comme le dispositif de l'art antérieur, le dispositif de l'invention comprend une partie de sangle 2 munie d'une portion dentée 20 et d'une bande à serrer 3 sur lequel est monté un organe de verrouillage 4 comprenant
- une
embase 42 fixée sur labande 3 ; - un cliquet 4 relié à l'embase par une
articulation 43 et ayant au moins une portion dentée complémentaire deretenue 410 destinée à coopérer avec la portion dentée 20 de la partie desangle 2 ; - un moyen de rappel élastique 44 qui maintient les portions dentées 20, 410 en contact l'une de l'autre en position de verrouillage et ;
- un
levier 45 actionnable à l'encontre de la force exercée par le moyen de rappel élastique 44 pour le désengagement des portions dentées 20, 410.
- a
base 42 fixed to thestrip 3; - a pawl 4 connected to the base by a
hinge 43 and having at least one complementarytoothed retaining portion 410 intended to cooperate with thetoothed portion 20 of thestrap part 2; - an elastic return means 44 which keeps the
20, 410 in contact with one another in the locked position and;toothed portions - a
lever 45 actuable against the force exerted by the elastic return means 44 for the disengagement of the 20, 410.toothed portions
Selon une caractéristique essentielle de l'invention, la partie de sangle 2
s'engage au travers de l'organe de verrouillage dans un espace 411 ménagé entre
l'articulation 43 et la portion dentée complémentaire de retenue 410 du cliquet 41 ;
la portion dentée complémentaire de retenue 410 se situant par rapport à
l'articulation 43 du côté d'engagement de la partie de sangle 2 dans l'organe de
verrouillage 4 de façon qu'en position de verrouillage, le couple de serrage qui
s'exerce par le cliquet 41 sur la portion dentée 20 augmente proportionnellement à
l'effort de traction exercée sur la sangle 2 dans le sens du désengagement de
l'organe de verrouillage 4. Ainsi également, l'action sur le levier 45 s'exerce dans
le sens de rotation C indiqué qui, quant à lui favorise l'éloignement de la bande
rembourrée 3 par rapport à la sangle dentée 2.According to an essential characteristic of the invention, the
Afin de faciliter l'introduction de l'extrémité 21 de la partie de sangle 2 dans
l'espace 411 de l'organe de verrouillage 4, l'embase est munie d'un bossage 420
à l'entrée de l'espace 411 du côté d'engagement de la partie de sangle.In order to facilitate the introduction of the
Comme le montre la figure 4, pour un encombrement minimal, le moyen de
rappel élastique 44 est avantageusement constitué d'un ressort de torsion 44
monté sur l'axe de l'articulation 43. L'un des bras du ressort est solidaire de
l'embase 42 alors que l'autre bras est rattaché sur le cliquet 41.As shown in Figure 4, for a minimum footprint, the means of
La portion de retenue complémentaire 410 du cliquet peut comprendre un
nombre variable de dents ; le choix de deux dents tel qu'illustré satisfait au
compromis à réaliser entre l'assurance d'un accrochage suffisant et une facilité de
désengagement.The
Comme expliqué précédemment, un tel dispositif de serrage est particulièrement
adapté pour équiper une fixation de surf de neige mais n'est pas uniquement limité
à cette utilisation. On peut envisager qu'un tel dispositif serve au serrage d'une
chaussure de sport par exemple. Dans ce cas, l'élément 3 à serrer peut être
différent d'une bande rembourrée. Il peut s'agir d'un volet ou rabat, par exemple,
de surface quelconque pouvant recouvrir une partie importante du pied.As explained above, such a clamping device is particularly
suitable to equip a snowboard binding but is not only limited
to this use. It is conceivable that such a device is used for tightening a
sports shoe for example. In this case,
