Definitions
- the invention relates to a device for closing and tightening for sports shoes, in particular ski boot, comprising a base, a lever articulated tensioner on this base, an articulated tie rod on the tensioning lever and fitted with a connecting piece at least part of which is in the form of a loop consisting of two arms connected at their ends by a transverse part intended to hang on on a projection of a hanging piece.
- Such a hanging device is, today, usually made of aluminum alloy parts injected or extruded and machined, except for the pins hinge and tie rod.
- the shaped part loop of the connecting piece is also not entirely made up of an injected metal part, but the end of the loop on which is exerted the force of the protrusion of the attachment piece is consisting of a steel bar.
- This bar has so far been considered necessary for withstand the clamping force. Now, this bar complicates the manufacture of the connecting piece and harms the aesthetics of the closure and tightening device because it prevents the height of the workpiece from being reduced liaison. A certain amount of matter must indeed be present below and above the bar, so the height of the connecting piece at this place will always be significantly greater than bar diameter.
- the aesthetics of tightening devices for a sports shoe, particular those of a ski boot plays a role not negligible in the buyer's decision.
- the object of the present invention is to simplify the manufacturing the clamping device and improving it aesthetics.
- the closing and tightening device is characterized in that the two arm and the transverse part of the connecting piece are in a single metal part injected or machined by removal of material.
- the height of the connecting piece at its end can thus be reduced to the thickness of its part transverse.
- the metal used will generally be an aluminum alloy. Injection or machining allows to give a harmonious shape to the end of the connecting piece, which turns out strong enough to withstand the stresses to which it is generally subject.
- Figure 1 shows a perspective view and the Figure 2 a top plan view.
- the device shown comprises a base 1 provided with two cheeks 2 and 3 between which is articulated a tension lever 4 around an axis 5.
- the tension lever 4 has a longitudinal cutout 6 forming two arms between which is articulated, around an axis 7, a tie 8 consisting, in a known manner, of a first partly tubular part into which is screwed a rod 8a at the end of which is articulated a connecting piece 9 around a transverse axis 10.
- the part 9 has a part 9a in the form of a loop consisting of two arms 9b and 9c connected to their ends by a transverse part 9d intended for come and hang on one of the projections 12 of a part attachment 11 on which are fixed several projections 12, here mushroom-shaped, so as to constitute a kind of rack.
- the tensioning lever 4 and the connecting part 9 are injected parts, for example aluminum alloy.
- the room hook 11 could consist of a injected rack.
- the connecting piece 9 therefore consists of a single room.
- the width, measured in the longitudinal direction, from the transverse end 9d of the loop 9a, which comes to hang on a projection 12, is relatively small because this part, which replaces the bar, must ability to easily engage between two projections 10 consecutive. Surprisingly, it turns out however, this width is sufficient to ensure the necessary resistance of the connecting piece 9 during tightening and subsequent forces on the device.
- the molding allows great freedom of form with regard to concerns the end of the loop. It can in particular present harmonious rounding, as it appears in the drawing (figure 2), or on the contrary a shape rectangular.
- the injection or machining by removing material from the part 9d transverse allows shapes adapted to the shape of the rack, such as the rounded shape shown which adapts to the rounded shape of the mushrooms 12, so that the pressure of the mushroom on the loop is spread instead of exercise punctually as would be the case with a cylindrical bars.
- the part of the connecting piece on the axis side 10 could be made of synthetic material.

Abstract
Description
L'invention concerne un dispositif de fermeture et de serrage pour chaussure de sport, en particulier chaussure de ski, comprenant une embase, un levier tendeur articulé sur cette embase, un tirant articulé sur le levier tendeur et muni d'une pièce de liaison dont une partie au moins est en forme de boucle constituée de deux bras reliés à leurs extrémités par une partie transversale destinée à venir s'accrocher sur une saillie d'une pièce d'accrochage.The invention relates to a device for closing and tightening for sports shoes, in particular ski boot, comprising a base, a lever articulated tensioner on this base, an articulated tie rod on the tensioning lever and fitted with a connecting piece at least part of which is in the form of a loop consisting of two arms connected at their ends by a transverse part intended to hang on on a projection of a hanging piece.
Un tel dispositif d'accrochage est, aujourd'hui, généralement constitué de pièces en alliage d'aluminium injecté ou extrudé et usiné, à l'exception des axes d'articulation et du tirant. La partie en forme de boucle de la pièce de liaison n'est pas non plus entièrement constituée d'une pièce métallique injectée, mais l'extrémité de la boucle sur laquelle s'exerce l'effort de la saillie de la pièce d'accrochage est constituée d'une barrette en acier. Cette barrette a jusqu'ici été considérée comme nécessaire pour supporter l'effort de serrage. Or, cette barrette complique la fabrication de la pièce de liaison et nuit à l'esthétique du dispositif de fermeture et de serrage car elle empêche de réduire la hauteur de la pièce de liaison. Une certaine quantité de matière doit en effet être présente en dessous et au dessus de la barrette, de sorte que la hauteur de la pièce de liaison à cet endroit sera toujours sensiblement supérieure au diamètre de la barrette. Or, l'esthétique des dispositifs de serrage d'une chaussure de sport, en particulier ceux d'une chaussure de ski joue un rôle non négligeable dans la décision de l'acheteur.Such a hanging device is, today, usually made of aluminum alloy parts injected or extruded and machined, except for the pins hinge and tie rod. The shaped part loop of the connecting piece is also not entirely made up of an injected metal part, but the end of the loop on which is exerted the force of the protrusion of the attachment piece is consisting of a steel bar. This bar has so far been considered necessary for withstand the clamping force. Now, this bar complicates the manufacture of the connecting piece and harms the aesthetics of the closure and tightening device because it prevents the height of the workpiece from being reduced liaison. A certain amount of matter must indeed be present below and above the bar, so the height of the connecting piece at this place will always be significantly greater than bar diameter. The aesthetics of tightening devices for a sports shoe, particular those of a ski boot plays a role not negligible in the buyer's decision.
La présente invention a pour but de simplifier la fabrication du dispositif de serrage et d'en améliorer l'esthétique.The object of the present invention is to simplify the manufacturing the clamping device and improving it aesthetics.
A cet effet, le dispositif de fermeture et de serrage selon l'invention est caractérisé en ce que les deux bras et la partie transversale de la pièce de liaison sont en une seule pièce métallique injectée ou usinée par enlèvement de matière.To this end, the closing and tightening device according to the invention is characterized in that the two arm and the transverse part of the connecting piece are in a single metal part injected or machined by removal of material.
La hauteur de la pièce de liaison à son extrémité peut ainsi être réduite à l'épaisseur de sa partie transversale.The height of the connecting piece at its end can thus be reduced to the thickness of its part transverse.
Pour des raisons de coût et de poids, le métal utilisé sera généralement un alliage d'aluminium. L'injection ou l'usinage permet de donner une forme harmonieuse à l'extrémité de la pièce de liaison, laquelle s'avère suffisamment résistante pour supporter les efforts auxquels elle est généralement soumise.For reasons of cost and weight, the metal used will generally be an aluminum alloy. Injection or machining allows to give a harmonious shape to the end of the connecting piece, which turns out strong enough to withstand the stresses to which it is generally subject.
Le dessin annexé représente, à titre d'exemple, un mode d'exécution de l'invention.The accompanying drawing shows, by way of example, a mode of the invention.
La figure 1 représente une vue en perspective et la figure 2 une vue en plan de dessus. Figure 1 shows a perspective view and the Figure 2 a top plan view.
Le dispositif représenté comprend une embase 1 munie de
deux joues 2 et 3 entre lesquelles est articulé un
levier tendeur 4 autour d'un axe 5. Le levier tendeur 4
présente une découpe longitudinale 6 formant deux bras
entre lesquels est articulé, autour d'un axe 7, un
tirant 8 constitué, de manière connue, d'une première
pièce en partie tubulaire dans laquelle vient se visser
une tige 8a à l'extrémité de laquelle est articulée une
pièce de liaison 9 autour d'un axe transversal 10. La
pièce 9 présente une partie 9a en forme de boucle
constituée de deux bras 9b et 9c reliés à leurs
extrémités par une partie transversale 9d destinée à
venir s'accrocher sur l'une des saillies 12 d'une pièce
d'accrochage 11 sur laquelle sont fixées plusieurs
saillies 12, ici en forme de champignon, de manière à
constituer une sorte de crémaillère. Le levier tendeur
4 et la pièce de liaison 9 sont des pièces injectées,
par exemple en alliage d'aluminium. La pièce
d'accrochage 11 pourrait être constituée d'une
crémaillère injectée.The device shown comprises a
La pièce de liaison 9 est donc constituée d'une seule
pièce. La largeur, mesurée dans le sens longitudinal,
de l'extrémité transversale 9d de la boucle 9a, qui
vient s'accrocher sur une saillie 12, est relativement
petite car cette partie, qui remplace la barrette, doit
pouvoir s'engager facilement entre deux saillies 10
consécutives. De manière surprenante, il s'avère
toutefois que cette largeur est suffisante pour assurer
la résistance nécessaire de la pièce de liaison 9 lors
du serrage et des efforts subséquents sur le
dispositif. A part cette contrainte de largeur, le
moulage autorise une grande liberté de forme en ce qui
concerne l'extrémité de la boucle. Elle peut notamment
présenter des arrondis harmonieux, comme ceci apparaít
dans le dessin (figure 2), ou au contraire une forme
rectangulaire. Sur le plan technique l'injection ou
l'usinage par enlèvement de matière de la partie
transversale 9d autorise des formes adaptées à la forme
de la crémaillère, telle que la forme arrondie
représentée qui s'adapte à la forme arrondie des
champignons 12, de telle sorte que la pression du
champignon sur la boucle est répartie au lieu de
s'exercer ponctuellement comme ce serait le cas d'une
barrettes cylindrique.The connecting
La partie de la pièce de liaison côté axe 10 pourrait
être en matière synthétique.The part of the connecting piece on the
