Abstract

Ski boot comprising an integral multi directional binding. It comprises: a transverse recess (62) made in the sole (7) of the boot (3), having two depressions interacting, respectively, with a front retention element and a movable rear piece which can slide and pivot; a block (4), which is integral with the ski (1), carrying both at the front and at the rear means for locking onto the front and rear faces of the said recess (62). <IMAGE>

Description

The invention relates to a new type of ski boot integrated into a multidirectional safety binding.

• - une butée avant, destinée à coopérer avec la pointe de la chaussure, dénommée également "le nez",
• - une talonnière arrière, destinée à coopérer avec le talon de la chaussure.

As we know, a traditional security binding essentially consists of two parts:

• a front stop intended to cooperate with the toe of the shoe, also called "the nose",
• - a rear heel, intended to cooperate with the heel of the shoe.

To allow the adaptability of the bindings to the different kinds of shoes, the front (nose, toe) and rear (heel) areas of the shoes have standardized dimensions.

• - comme la butée et la talonnière sont éloignées du centre de pivot, en cas de chute, on a une inertie importante, donc un temps de réponse substantiel, donc des risques. de fractures avant l'ouverture de la fixation ;
• - la nécessité d'adapter l'écartement entre la talonnière et la butée pour chaque pointure de chaussure ;
• - l'obligation de faire appel à deux dispositifs distincts pour assurer la sécurité :
  • . la talonnière pour les chutes avant,
  • . la butée avant pour les chutes latérales, alors que ces deux dispositifs ne coopèrent pas et n'interréagissent pas entre eux ; ainsi, lors d'une chute, la chaussure est soumise à une torsion, de sorte que l'ouverture de la fixation ne se fait pas toujours dans les conditions idéales prévues.

Although very widespread, these fasteners have many disadvantages. We can cite :

• - as the stop and the heel are distant from the pivot center, in the event of a fall, there is a significant inertia, therefore a substantial response time, therefore risks. fractures before the opening of the binding;
• - the need to adapt the spacing between the heel piece and the stop for each shoe size;
• - the obligation to use two separate devices to ensure security:
  • . the heel piece for front falls,
  • . the front stop for lateral falls, while these two devices do not cooperate and do not interact with each other; thus, during a fall, the shoe is subjected to a twist, so that the opening of the binding is not always done under the ideal conditions provided.

Recently, it has been proposed to produce integrated shoe-binding assemblies.

In a first commercial version, the sole of the shoe has two recesses one on the front, the other on the rear, intended to cooperate with a stop and a heel whose spacing is constant. If this is done by eliminating the problem due to the adjustments according to the sizes, on the other hand, these shoes cannot be used on other types of binding. Finally, here again, heel piece and toe stop work separately. In addition, these sets provide no safety during rear falls

In a second version, also sold, described in particular in the French patent applications published under the numbers A2.409.063 and 2 409 064 (US-SN 853.258 and 853.500 of November 21, 1977), it was proposed to provide a plate under the sole of the shoe intended to cooperate with a protruding locking member - subject to skiing. If safety is thus fairly well ensured during combined falls, on the other hand, this device remains dangerous and hinders walking due to the fact that it is protruding and that sometimes the boot is not perfectly maintained on the ski. (see also patent US-A-3,902,729 and Canadian 926,889).

In patent US-A-3,061,325, an integrated assembly has been described: boot-binding, in which the boot has a recess where an element integral with the ski is housed. Unfortunately, this solution on the one hand can work only in all or in nothing and on the other hand, is completely ineffective during lateral falls and is even sometimes dangerous.

In an improved version described in US Pat. Nos. 3,869,136 and 3,957,280, the ski comprises a block intended to engage in the recess formed in the sole of the shoe. In order to secure this ski to the boot, this block has at the front and at the rear locking members, such as springs associated with balls, intended to bear on the front and rear faces of the recess . To improve the interlocking of the boot on the ski and avoid slipping from one with respect to the other, the internal face of the recess and the upper face of the block have inverted grooves intended to cooperate with each other. Unfortunately, this arrangement does not provide any elastic stroke avoiding untimely openings, in particular during front upward falls, and also only provides an often questionable connection of the whole shoe. (see also in the same sense the French patents published under the number A 2 470 617, the Austrian B 317 740 and the German A 2 311 175).

The invention overcomes these drawbacks. It relates to a new type of ski boot and integrated safety binding which is effective as well during falls before as rear falls, as side or combined, while remaining adaptable to any shoe sizes in addition and above all ,. this new device according to the invention comprises an elastic return stroke which we did not know how to obtain until then. In other words, this new device allows the binding to be triggered, that is to say to open only when one has reached predetermined limit values, otherwise this device allows to go back, this which usefully avoids untimely openings caused in the devices mentioned in the preamble by the fact that we could not go back.

• - l'un faisant partie intéqrante de la chaussure constitué par un évidement transversal ménaqé dans la semelle de la chaussure,
• - l'autre fixé au ski constitué par un bloc solidaire du ski portant à l'avant comme à l'arrière des moyens de blocage sur les faces avant et arrière dudit évidement,

This multidirectional shoe-binding composed of two sets namely:

• one being an integral part of the shoe constituted by a transverse recess menaqé in the sole of the shoe,
• the other fixed to the ski constituted by a block integral with the ski carrying, at the front as at the rear, locking means on the front and rear faces of said recess,

characterized :

• - in that the block fixed to the ski includes:
  • . at the front, a means intended to be housed under the corresponding recess in the hollow of the sole of the boot, capable of ensuring the maintenance of the boot on the ski and of ensuring the release of the boot during a rear fall ,
  • . and at the rear, a movable part capable of sliding in a horizontal plane and of pivoting on itself, intended to be housed under the correspodant hollow part of the sole of the shoe, against which it is held in pressure;
• - And in that the transverse recess formed in the sole of the ski boot comprises on each of these two front and rear faces, two recesses intended to cooperate respectively: -
  • . on the front, with said holding means,
  • . on the back, with the sliding and swiveling moving part.

In a first embodiment, the holding means located at the front is formed by a fixed horizontal lug, the disengagement then taking place thanks to the compression and the pivoting of the rear movable part.

• - le moyen de maintien situé à l'avant est formé par un ergot coulissable dans un plan horizontal selon l'axe longitudinal, maintenu en pression par le même moyen de compression agissant sur la pièce mobile arrière coulissable et pivotable, par exemple un ressort spiralé ;
• - le moyen de maintien situé à l'avant a une forme générale vue de dessus légèrement arrondie et a une section générale en forme de V dissymétrique ouvert vers le bas ; le dessous de la semelle de la chaussure présente alors à l'avant un décrochement femelle de forme correspondante ; afin d'assurer une meilleure tenue verticale de la chaussure pendant l'action du skieur, la face inférieure du V dissymétrique présente une légère rainure qui formera ainsi un point précis de déclenchement lors des chutes arrières ;
• - la pièce mobile coulissable pivotante, maintenue en compression par un ressort dont la pression est réglable, présente deux lumières symétriques dans lesquelles sont engagés deux axes verticaux, la face arrière de cette pièce ayant :
  • . vu de dessus, une forme générale en V ou en U dont les deux branches se raccordent par une portion d'arc de cercle,
  • . vu en coupe, une forme de V dont la branche supérieure est inclinée vers le haut pour assurer la mise en place de la chaussure, alors que la branche inférieure est inclinée vers le bas pour assurer le dégagement lors des chutes avant ou combinées ;
• ' - l'arrière de la chaussure présente un moyen pour permettre le dégagement de la chaussure à l'arrêt : ce moyen de dégagement est constitué par un levier escamotable lors -de la marche,qui est solidaire du talon de la chaussure et prend appui sur le ski lui-même.

In a second preferred embodiment:

• the holding means situated at the front is formed by a lug which can be slid in a horizontal plane along the longitudinal axis, kept in pressure by the same compression means acting on the rear movable part which can be slidable and pivoted, for example a spiral spring ;
• - The holding means located at the front has a general shape seen from above slightly rounded and has a general section in the shape of an asymmetrical V open towards the bottom; the underside of the sole of the shoe then has at the front a female recess of corresponding shape; to ensure better vertical hold of the boot during the action of the skier, the face lower of the asymmetrical V has a slight groove which will thus form a precise trigger point during rear falls;
• - the pivotable sliding movable part, kept in compression by a spring whose pressure is adjustable, has two symmetrical openings in which two vertical axes are engaged, the rear face of this part having:
  • . seen from above, a general V or U shape whose two branches are connected by a portion of an arc of a circle,
  • . seen in section, a V-shape, the upper branch of which is inclined upward to ensure the fitting of the boot, while the lower branch is inclined downward to ensure clearance during front or combined falls;
• '- the rear of the shoe has a means for allowing the release of the shoe when stationary: this release means is constituted by a retractable lever during walking, which is integral with the heel of the shoe and is supported on the ski itself.

Figure 1 schematically shows a ski (1) with its tip (2) equipped with a shoe assembly (3) -binding block (4) integrated, multidirectional, fixed - to the ski (1).

• - dans la direction de l'avant du ski un ergot horizontal (11) ayant, vu de dessus, une forme générale (12) légèrement arrondie (voir figure 15) et une section générale (13) en forme de V dissymétrique ouvert vers le bas. Cet ergot (11) apte à coulisser dans un plan sensiblement horizontal par rapport au ski est maintenu en pression par un ressort spiralé (voir figures 6 et 7) ; cet ergot est destiné à assurer le maintien de la chaussure sur le ski et à assurer le dégagement de la chaussure lors des chutes arrières ;
• - dans la direction de l'arrière du ski, un logement (15) où viendra se loger la pièce mobile coulissable et pivotante détaillée aux fiqures 3 à 5.

Figure 2 shows in summary perspective view the block assembly (4) fixed to the middle part (5) of the ski (1) by screws (6). This assembly is formed by a block (10) of molded plastic (polyamide, polyacetal) on which is pressed a cover (14) also molded. This block (10) which can be monobloc has:

• - in the direction of the front of the ski, a horizontal lug (11) having, seen from above, a general shape (12) slightly rounded (see FIG. 15) and a general section (13) in the shape of an asymmetrical V open towards the low. This lug (11) capable of sliding in a substantially horizontal plane relative to the ski is kept under pressure by a spiral spring (see Figures 6 and 7); this lug is intended to ensure the retention of the boot on the ski and to ensure the release of the boot during rear falls;
• - in the direction of the back of the ski, a housing (15) where will be accommodated the sliding and pivoting movable part detailed in Figures 3 to 5.

• - la rampe supérieure (25),à la mise en place de la chaussure (3),
• - la rampe inférieure (26), au dégagement de la chaussure'(3) lors d'une chute.

This moving part (20) (see FIGS. 3, 4 and 5) also made of plastic or of molded metal (for example of aluminum molded by gravity), has, seen from above, on the side of the rear male face intended to come in contact with the shoe, a general shape of a very flat V, or even a U, the branches (22) and (23) of which are connected by a portion of an arc of a circle (24), intended to maintain and to center the boot (3) when skiing. The branches (22-23) of this horizontal V are bordered by fittings (21). In section, this rear face has two ramps (25) and (26) also in the form of a V intended respectively:

• - the upper ramp (25), when the boot (3) is in place,
• - the lower ramp (26), when the boot is released (3) during a fall.

As will be seen later, these ramps (22-23) of the horizontal V play during lateral falls, while the ramps (25) and (26) of the vertical V play during forward falls.

The front face (27) of this movable part (20) has a cup (28) intended to receive the hemispherical bearing head (29) of a spring. horizontal spiral (30) of compression. In order to create a better centering of the boot (3) in the axis of the ski and a hard point opposing untimely lateral releases, the bottom of this bowl (28) can be dug so as to receive this support head (29).

Finally, this moving part (20) has two openings (31-32), symmetrical with respect to the longitudinal axis (33), slightly curved towards this axis (33), in which two vertical axes (34) are housed and (35) fixed in the base of the body (10). These lights (31-32) thus allow the horizontal sliding of the part (20) towards the front of the shoe (recoil) and their curvature allows the part (20) to pivot around the two vertical axes (34) and (35) by compressing the spring (30) using the head (29).

Thus the two reversing and pivoting functions are combined.

The characteristic moving part (20) is positioned in a plane parallel to the upper face (36) (see FIG. 2) of the cover (14) of the body (10) and slides and pivots in a housing (37) (see FIG. 14) provided for this purpose in the body (10). It should be emphasized that the plane of the middle portion (5) of the ski and that of the upper face (36) of the body (10) fixed on this portion (5) are not parallel, but form an angle of the order about 10 degrees (see Figure 7), so as to allow easy installation of the heel of the shoe in the recess provided for this purpose by a sufficient compression stroke.

The other end of the spring. compressed compressed (30) is encased in a stop (40) which bears on the sliding lug (11). By a suitable thread (41), this stop (40) can slide horizontally in a housing (42) provided for this purpose in the body (48) of the lug (11). A lateral adjustment screw (43) which acts on a pinion (44) and on a return (45), cooperates with the thread (41), which by turning thus displaces the stop (40) longitudinally and consequently compresses the spring and gives the desired hardness setting. You can replace the assembly (44-45) with a transverse cable.

This assembly is placed in a housing (46) provided for this purpose in the block (10).

In a variant, the support head (29) has a longitudinal channel in which will be accommodated a rigid but flexible rod, such as a piano cord whose end opens out inside the calibrated spring (30). In this way, during a lateral release, this piano cord will tend to bring back the moving part (20) in the longitudinal axis of the ski and consequently, the boot. On the other hand, this piano cord has no action during a forward fall.

The lower front face (47) of the lug (11) proper, is inclined towards the ski so as to ensure the control of rear falls. If this lug (11) was fixed and not slidable as shown, we would no longer control these rear falls.

Figure 8 shows another embodiment of the invention in which the body (48) of the lug (11) has a channel (50) which ends in a threaded portion (51), in which will be housed a threaded pin (52) in support of the stop (40). Thus by passing a screwdriver in this channel (50), one can adjust the pressure, therefore the hardness of the spring (30).

In addition, this body (48) slides on two rails (53) and (54) provided for this purpose at the edge of the housing (46).

The lateral edges (55) and (56) of the lug proper (11) are bevelled in order to serve as a fulcrum and pivot point for the shoe (3) during a lateral fall in the direction of the side opposite.

The sole (7) of the shoe (3) (see FIGS. 9 to 11) has a standardized nose (60) at the front and a heel (61) also standardized at the rear.

• - à l'avant, une entaille femelle (63) en forme de décrochement avec deux rebords (64) et (65) et une rampe (66) inclinée vers l'arrière ; cette rampe (66) présente une inclinaison identique mais complémentaire à celle de la rampe (47) de l'ergot (11), de manière à coopérer par emboitement avec celle-ci ; de même les pentes et les dimensions des rebords (64) et (65) sont identiques,mais complémentaires des rebords inclinés (55) et (56) de l'ergot (11) ;
• - à l'arrière, un bossage (67) arrondi également, formant décrochement, venu de moulage, comportant deux rampes (68), (69) inclinées, mais d'inclinaisons identiques et complémentaires aux rampes (25), (26) de manière à coopérer par emboitement avec celles-ci ; (90) désigne une plage d'appui pour la face supérieure de (20).

The interior (62) of this sole (7) of this shoe is hollowed out transversely and has:

• - At the front, a female notch (63) in the form of a recess with two flanges (64) and (65) and a ramp (66) inclined towards the rear; this ramp (66) has an identical but complementary inclination to that of the ramp (47) of the lug (11), so as to cooperate by interlocking therewith; similarly the slopes and the dimensions of the flanges (64) and (65) are identical, but complementary to the inclined flanges (55) and (56) of the lug (11);
• - At the rear, a boss (67) also rounded, forming a recess, molded, comprising two ramps (68), (69) inclined, but with inclinations identical and complementary to the ramps (25), (26) so as to cooperate by interlocking therewith; (90) designates a bearing surface for the upper face of (20).

The shoe (3) is made of semi-rigid injected plastic (polyurethane, A B S ...). Advantageously, the sole and more precisely the contact zones (63-64-65-67-68-69) with the safety fastening assembly are made of a semi-rigid self-lubricating material, mechanically resistant and to abrasion. (polyamide, PTFE ...). In known manner, the sole also includes a stiffening shank (70).

The fitting of the shoe (3) on the fixing block is carried out as follows.

The fit skier introduces the front female notch (63) on the sliding lug (11) of the block (10) of the binding. ' He then moves his foot back to properly engage the ramp (66) on the corresponding ramp (47). It then carries all its weight in the back. At this time, the ramp (68) comes into contact with the ramp (25) of the branches (22-23.) In V of the moving part (20). In doing so, the ramp (68) slides on this ramp (25) and thus slides the moving part (20) in a horizontal plane while compressing the spring (30), which simultaneously ensures better compression on the front side. ramp (66) on the ramp (47). When the top of this male ramp (69) passes over the top of the ramp (25), the lower ramp (26) immediately comes to press firmly against the male ramp (68) to ensure the nesting under the effect of compression of the spring (30). The shoe (3) is then locked on the ski (1). In this position, there is nevertheless a slight clearance between the underside of the sole (7) and the middle portion (5) of the ski, so as to eliminate friction.

During a front fall, the sole (7) of the shoe rises from the rear. Then, the ramp (69) of the sole stresses the lower ramp (26) of the moving part (20) by compressing the spring (30). This spring (30) is adjusted to the desired hardness, so as not to inadvertently play the binding. A lateral fall causes on the pivoting sliding movable part (20) a lateral force which initially slides this part (20) by tilting it around the vertical axis (35-36) situated opposite this force while compressing the spring (30), in order to also avoid untimely openings. More precisely, during a fall to the right, the right portion of the lower ramp (68) of the sole presses on the right portion of the lower ramp (26) of the moving part (20), which then makes this pivot piece (20) around the left vertical axis (35). On the other hand, during a fall to the left, the pivoting takes place in the same way, but around the right vertical axis (36).

During a rear fall, the ramp (66) of the sole requests the lower ramp (47) of the lug (11) which then slides longitudinally by compressing this same spring (30).

During combined falls, that is to say front (or rear) and lateral falls, falls which by far are the most frequent and which unfortunately do not allow to control the current conventional safety bindings, then all possible combinations are carried out of these different movements.

During a lateral fall with oblique release, the horizontal lateral displacement causes the tilting of the horizontal V-shaped ramps (22-23), while the oblique force component acts on the ramps (25-26) causing compression of the spring (30). As these two pairs of ramps (22,23,24,25,26) are joined in a single piece (20) and in the same place, there is indeed a simultaneous action in both directions. So the final force component can play in any direction, which ensures heaving in the best conditions of safety.

So we did a multidirectional assembly well, which we didn't know how to do until then.

In another improved embodiment not shown, the boss (67) of the sole has in its center another male boss intended to be received in the arcuate connection (24) to thus form a hard point and ensure a better support of the boot (3) on the ski (l). Indeed, so that this male boss can leave this cup (24), it is necessary to exert appreciable compression forces on the spring (30), which avoids untimely openings and above all allows to maintain well and if necessary to permanently return the foot in the longitudinal axis (33), that is to say in the axis of the ski (1) during skiing.

• - une petite portion (82) destinée à prendre appui sur le ski (l) lors du basculement, située au niveau de l'axe de pivotement (81) ;
• - une rampe de raccordement (83) qui s'appuiera sur le ski (1) et plus précisément sur la portion médiane (5) afin d'assurer l'effort d'ouverture ;
• - puis un bras de levier (85) ;
• - et enfin une surface d'appui (86).

To ensure heaving (see Figures 12 and 13), the bottom of the heel (61) has a rigid lever (80) in the shape of a pedal, for example made of plastic or of molded metal, articulated at the base around an axis. horizontal (81) passing through (91). This pedal (80) comprises in order:

• - A small portion (82) intended to bear on the ski (l) during tilting, located at the pivot axis (81);
• - A connection ramp (83) which will rest on the ski (1) and more precisely on the middle portion (5) in order to ensure the opening force;
• - then a lever arm (85);
• - And finally a bearing surface (86).

When skiing, this pedal (80) is in the position shown in Figure 12, that is to say in the extended position. When the skier wants to take off his shoes, he just has to press on the bearing surface (66). In doing so, the connector (84) then comes to bear on the ski (1) and thanks to the axis (81) raises the sole (7). We therefore find ourselves in the same conditions as in a forward fall which would then be caused, and the release is done under the same conditions.

When he wants to walk, the skier (see Figure 13) switches this pedal (80) under the sole (7) until it comes to fold it into a housing (83) provided for this purpose. In this way, this pedal (80) does not interfere when walking.

Similarly, when the skier equipped with this ski boot (3-7) wants to practice skiing with traditional safety bindings, he just has to fold this pedal (80) as before. He then locks the shoe on the toe and the heel thanks to the nose (60) and the heel (61) standardized. In this case, the lever (85) is supported on the ski and in particular on the different types of ski brakes.

• - l'absence de réglage de l'écartement butée-talonnière en fonction des pointures, ce qui est idéal pour un parc de location ;
• - la possibilité pour la chaussure de pouvoir néanmoins s'adapter aux fixations classiques normalisées du marché
• - la sécurité nettement améliorée, puisque le même dispositif est multidirectionnel et agira aussi bien lors des chutes avant, des chutes arrière, des chutes latérales ou même des chutes combinées ;
• - la possibilité d'avoir une grande course élastique avant le déclenchement de l'ouverture, ce qui évite les déchaussages intempestifs ;
• - la légèreté et la compacité ;
• - le nombre restreint de pièces par rapport aux fixations traditionnelles ;
• - l'obtention d'un point de pivotement ergonométri- que, puisque l'axe général de pivotement et de déclenchement du dispositif est pratiquement confondu avec l'axe de la jambe.

The integrated shoe-binding assembly according to: the invention has numerous advantages over the solutions marketed to date. We can cite :

• - the absence of adjustment of the heel-to-heel distance according to the sizes, which is ideal for a rental fleet;
• - the possibility for the shoe to nevertheless be able to adapt to standard standardized bindings on the market
• - significantly improved safety, since the same device is multidirectional and will act as well during front falls, rear falls, side falls or even combined falls;
• - the possibility of having a large elastic stroke before the opening is triggered, which avoids untimely heaving;
• - lightness and compactness;
• - the limited number of parts compared to traditional fixings;
• - obtaining an ergonometric pivot point, since the general pivot axis and triggering of the device is practically confused with the axis of the leg.
