Abstract

The invention concerns fixing elements for snowboards or other gliding boards. The device comprises coupling, locking, adjusting, clamping means and is characterized in that the adjusting means consist of upper slides (8) secured to the coupling means of the shoe, lower slides (9) secured to the gliding board and in that the clamping means consist of parts (30', 30') sliding in the upper and lower slides and a clamping mechanism (7,32,30) compressing the upper slides on the lower slides. The coupling means may be of various types depending on the type of sport. Said device solves once and for all conventional problems of snowboard fixing elements by providing in combination solutions for: easy fitting and adjusting, maximum feedback by directly pressing the shoe on the snowboard, compatibility with the natural flexion of the board, greater power in the transmission of support contacts, as well as hitherto unknown possibilities of modifying the angle and position of the shoe without losing same even while gliding such as when surfboarding.

Description

DEVICE FOR RETAINING A SHOE ON A SLIDING BOARD

The invention relates to a device for retaining a shoe on a gliding board, especially on snow.

Terminological details: to facilitate the reading the usual anglicism "snowboard" will be used instead of "snow board". On the other hand throughout the document "longitudinal" and "transverse" refer to the large and small axis of the snowboard, "fore", "front", "rear", "rear" refer to the front and rear of the shoe fixed by the device.

STATE OF THE ART FIXING TYPES FOR SNOWBOARD AND THE PROBLEMS THEY PUT

Experienced tradesmen or snowboarders know that despite twenty years of industrial development and the development of many models of a wide variety, the problem of snowboard bindings is not solved satisfactorily: it is For example, it is impossible to find a binding that combines ease of entry and steering precision, or even simply a binding whose position on the snowboard can be easily adjusted. Here is a synthetic overview of the four types of snowboard bindings currently in use and the problems associated with them:

STRAPPED FASTENERS

These fasteners are usually called "hulls" or "hulls" or "strap-in" fasteners in English. These are the oldest fixtures and remain the most used (eg US6773020). They fix the shoe by manually tightening two straps, the shoe being pushed down against the base of the binding and back to a gutter usually called "spoiler".

Problems posed by this type of fixation:

- The difficulty of setting up the shoe and the manual tightening of the straps, which may take several tens of seconds, requires bending down or sitting on the snow.

the inaccuracy of the position of the boot in the base, in particular its rear wedging, generating inaccuracies in the steering of the snowboard,

- depending on the model, various oversizes that are added under the shoe and reduce the feel and precision of snowboard control. AUTOMATIC FIXINGS

These fixations are usually referred to as "step-in" anglicism. As on the bindings for ski the shoe is fixed and locked automatically by a foot movement, without manual intervention. There is a wide variety of systems available and even sold (eg FR9914696, US6206402, US6105996)

Problems posed by this type of fixations:

- they work poorly, especially if snow or mud has settled on the binding. It must then be repeated several times, manually clean the system, which is exactly the opposite of the desired ease of use.

- They significantly reduce the accuracy of control on snowboarding by erasing the sensations experienced. It is important to understand the origin of this decrease to design a better fixation. It is due to two factors:

- the extra thickness added under the foot by this type of system which moves the foot away from the sole of the snowboard and thus reduces the precision of the sensations;

~ the poor transmission of the supports due to effects of leverage too short or damped by segments inflexible between: the attachment point of the shoe and the edges of the snowboard.

Because of these two drawbacks, especially of the second which is unacceptable for experienced snowboarders and looking for performance, the "step-in" bindings have not had the success initially expected by their promise of ease and the vast majority of snowboarders came back to traditional hull bindings.

REAR SHOE FASTENINGS

These fixings are usually referred to as "back-in" anglicism. These are hull fasteners with the spoiler opening towards the rear, allowing the boot to enter the binding from behind (eg US6003893). The intended ease of use is intermediate between "step-in" and hulls since it requires manual intervention to open and close the spoiler.

Problems posed by this type of fixation:

- the feeling of blocking the kick forward, prohibitive for about half of the snowboarders who try this type of fixation. It is due to the fact that the flexible tightening straps must be replaced by a very tight strap without tightness, this rigidity allowing both the penetration of the shoe and its blocking forward,

the difficulties of inserting the boot and locking the spoiler which appear in the steep slopes and when filling the binding with powdery snow: this system proves in these cases more difficult to use than a conventional binding with hulls. The "back-in" bindings nevertheless meet with some success and have taken 10 to 15% of the market.

FIXINGS FOR RIGID SHOES

The shoe is rigid and close to a ski boot. The binding blocks the shoe forward and back by two arches that support the flats of the shoe. The front hoop is articulated to allow to block and unlock the binding, by hand or by foot support on some automatic models.

Problems posed by this type of fixation: - The thickness added by the binding and the shoe is considerable (ex. US6773024), of the order of 3 or 4 cm which decreases all the sensations received at the foot,

- The binding is long and rigid and blocks the natural twist of the snowboard, which is separated into 3 independent torsion segments: in front of the front shoe, between the two shoes and behind the rear shoe. The natural behavior of the board is very modified. (This problem of modifying the flex also exists, less markedly, on many models in the other types of fixation.)

These bindings are of rare use, mainly for hard piste downhill snowboards.

IN TOTAL: the vast majority of snowboarders use the old type with hulls despite its problems of precision and especially of footwear,

ADDITIONAL PROBLEM COMMON TO ALL TYPES OF FASTENING USED; THE DIFFICULTY AND IMPRECISION OF ADJUSTMENT IN ANGLE AND POSITION

All types of commonly used bindings also suffer from the difficulty of changing the positioning of the bindings in angle and in longitudinal and lateral position on the snowboard. On most fasteners the adjustment means consist of a disk, most often notched on its periphery, which holds the base of the binding in position on the snowboard and allows its angular adjustment. The clamping means are constituted by 4 screws according to the standard spacing called "4x4" which grip this disc on the snowboard. Often there are several rows of holes in the disc or the holes are elongated in one direction, which allows a small additional adjustment in a longitudinal or transverse translation direction (not both). It takes between 10 and 20 minutes to disassemble the attachment, change its position, reassemble it, the operation can be made very difficult by the weather conditions.

This difficulty of adjustment poses a certain problem because the position of the foot relative to the snowboard is extremely variable. For example the angle of - A - back foot commonly varies from +20 to -15 degrees depending on the snowboarder or even the type of snow for the same demanding snowboarder. In translation the fasteners can be positioned generally only plus or minus 1 cm around the selected inserts. The accuracy of these movements and angulations is small, in steps of 3 or 5 degrees and 1/2 or 1 cm. The fact of not being able to change easily repels the beginner who in rule has tried only one position and thus uses the snowboard with a position which is very unlikely to be optimal for him. The demanding user will have found the optimal position but after long and tedious disassembly and reassembly of its fixings; he may remain however dissatisfied with the lack of precision of the positioning authorized by its fixing and also not being able to vary it according to the conditions without having to perform a disassembly.

This problem has received a lot of attention from the inventors (eg US6817622, US5791678) but without a complete solution providing adjustment without disassembly both in rotation and in translation is proposed and also without commercial success.

ANALYSIS - GENERAL DESIGN PROBLEM UNDERLYING ALL KNOWN TYPES OF FIXING FOR SNOWBOARD

It will be proposed that the problems mentioned in the preceding paragraphs stem from a general design problem underlying all these types of fixation, a problem solved by the proposed device. Indeed these types of bindings are not fully adapted to snowboard because their design is close to that of ski bindings: each attachment is attached symmetrically to the board completely independently of the other attachment. In other words, the design of these bindings do not use the fact that they are placed on the same board. Compared to ski bindings, these types of snowboard attachments simply add rotational adjustment. We could also use these bindings on skis after setting their orientation to 0 °. The object of the invention is to propose a general solution to this problem, which secondarily makes it possible to propose surprisingly effective derived solutions for each of the problems mentioned.

A search for very general keyword combinations that produce more than 1100 patent references shows that this underlying problem seems to have never been identified as such. GENERAL SOLUTION PROPOSED IN THE DEVICE

The fixing device proposed here is specific to the snowboard in that it uses the fact that the two shoes are placed on a single gliding board and that we can therefore distribute the binding half on each attachment, asymmetrically and unilateral, ie on one side of the shoe. There are several patents showing fasteners which are partially unilateral (US6209890, US6193245, US6050589, FR2740983, FR2745192), which do not have all the functional constituents -means of attachment, locking of hookup, adjustment, tightening of the setting - on one side of the shoe. This is due to the fact that in these patents the unilateral character does not answer to a general analysis of the problem posed by snowboard bindings, but to particular needs, for example to be able to take off during the execution of aerial tricks (US6193245), hanging in a visible way elsewhere than under the shoe (FR2745192), to be able to tilt the shoe laterally (FR2740983) etc. These patents are not currently used in commercial products.

In the embodiment shown in Figure 1 which describes a basic model, all the functional components of the fastener were positioned on the outer side, which is the preferred side for transmitting the forces - but an interior fixation could to be proposed. The user having a snowboard leg spread apart that constantly maintains the support side of the shoe, fixing this side of the shoe is indeed useless.

According to the embodiment, the unilateral fixing device offers a solution to each of the problems mentioned: SOLUTION OF THE "STEP-IN" LOCKING PROBLEM

In the basic model shown in FIG. 1, the locking of the boot is of the "step-in" type, the mechanism being positioned visibly and out of the snow, which solves the locking difficulties indicated in the state of the art. Moreover the attachment is done by a very simple movement of the foot from back to front and the locking is effected without effort by a rack effect.

SOLUTION TO THE PROBLEM DISCHARGE OF "STRAP-IN"

In the model presented from Figure 14 the attachment of the shoe is achieved by an articulated gutter that folds automatically. The one-sided character makes it possible to open the binding almost completely and makes fitting almost immediate to the insertion of the shoe. There are several patents for fixing where the attachment is made by articulated gutter, sometimes with automatic closure (US6588773, DE29520277, FR2829943, US6003893) but never unilaterally.

SOLUTION OF ANGLE AND POSITION ADJUSTMENT PROBLEMS Figure 1 shows that when the shoe-snowboard link is one-sided, it can be very easily mounted on a double longitudinal and transverse slide system freely positioned on top of each other and tightened by a lever to change in a few seconds the angle and the transverse and longitudinal positions of the shoe on the snowboard and with any the desired precision, moreover without having to remove the boot from the binding and therefore without any disassembly.

A double-slide system without unilateral arrangement is possible but it would be accompanied by a very complex bilateral unlocking system. Therefore, there is apparently no patent for a double-slider adjustment device that allows angle and position adjustment without loosening.

On the other hand, provided with a clamping means for maintaining an intermediate clamping level of the slides, the device opens a new area of snowboard use, the user can change the position of his feet during the slide, as the bottom surfboard surfers on sea.

SOLUTION OF THE PROBLEM OF THICKNESS UNDER SHOE AND THE MODIFICATION OF FLEX

In all the embodiments proposed in the figures, the shoe rests directly on the surface of the snowboard: there is no longer any thickness. On the other hand we note that the footprint of the binding on the snowboard is minimum which respects the natural flex of the board.

SOLUTION OF PROBLEM OF SUPPORT TRANSMISSIONS

In the embodiment of FIG. 7 intended for users requiring a great power of support, the points of support were removed at the snowboard level on two decks and at the level of the shoe they were positioned as far as possible that is to say at the front and back ends.

ADVANTAGESUPPLEMENTARY: VERSATILITY OF THE PROCESS

This unilateral dual-slide fastener is a new, very general type of fastener that differs from all known types; it can be declined in the form of many models according to the needs of users, professionals or manufacturers.

BASIC MODEL FOR OCCASIONAL USERS AND PROFESSIONAL RENTERS

- JI is a double-slide model allowing immediate adjustment in store and on track, but simplified and with only one point of attachment of the shoe

ADVANCED MODEL FOR DEMANDING USERS

- Double-zipper model and "step-in" type with double anterior and posterior grip on the shoe. - Ultra-light "step-in" models without slides and fixed fixed angles, for users who know their position and do not need to change it.

SPECIAL MODELS - Models accepting any flexible or rigid boot of the trade, type "step-in" with side use shoe removable fasteners, or type shells by the use of fixed straps.

- Modified snowboard models including one or two longitudinal rails in the body of the board.

- Triggerable models including a safety device automatically releasing the boot in case of shocks or torsion of the lower limbs as on ski bindings.

NOTE ON THE PURPOSE OF THE PRIORITY REQUEST

The present PCT application is intended to be a lining, ie to gather the two applications FR 0509672 and FR 0511140 of the same inventor and to enhance the work done by their examiner by refocusing the claims on the double adjustment device. slides. Indeed the initial drafting of the claims focused on the totally unilateral nature of the fixation, which was recognized as new and inventive but accompanied by cited documents showing partially unilateral fixations. On the other hand, no document cited showed adjustable fixing by a device with double slide allowing an adjustment in angle and position without heaving. The examiner himself referred to the ease of adjustment as the main purpose of the device. The first demands will seek to obtain stronger protection, based on what has emerged as the core of the innovation, and wider, that is to say also covering devices with double slide without unilateral character.

The various non-limiting embodiments of the invention will be better understood in the detailed description which follows and the figures attached thereto.

As seen in Figures 1 and 2 the attachment comprises a plate (1) fixed to the snowboard (0) by the screws (14) and receiving a bar (2), this bar supporting the clamping means (6) in particular its lever (7), as well as the rear hooking means (5) and the front hooking means (4) which cooperates with the locking means (20).

Thus the binding is unilateral, the shoe being fixed, locked and its position on the snowboard tight, from a single of its sides.

PROGRESSIVE LOCKING AND FREEZING MEANS (FIGS. 1, 2, 6 and mainly 3 and 4), The shoe fastener is locked by the rod (10) fixed to the shoe when it enters the tube ( 19) belonging to the front attachment device (4) which is fixed to the front of the bar (2) via a spacer (16) which positions this device above the snow accumulations. The latch (20) consisting of a semicircular axis, held in the housing (21) by the screwed ring (22), receives the rod (10) on the segment (23) on its flat side. The axis is pushed and counter-clockwise into the tube (19) which opens the light of this tube as can be seen on the right half of Figure 3. In a reverse movement of the rod (10) ), the semicircular axis closes the tube of the light (19) by clockwise rotation and thereby blocks this withdrawal movement of the rod and the shoe. To release the user opens the tube light (19) by rotating counterclockwise the latch with the lever (15) which does not require effort because it is the round part of the semi-circular axis which rubs on the rod (10); he can then make a foot movement backwards which removes the rod (10) and releases the boot from the binding.

The latch (20) is biased to the closed position by an elastomeric block (not shown) located at the location (24) and pressing on the flat segment (25), thereby rotating it clockwise, until the contralateral flat segment (26) comes into contact with the face (27) of the triangular abutment (28) fixed to the bottom of the housing (21). The left half of FIG. 3 shows this rest position where the tube lumen (19) is closed by the latch (20).

The rod (10) being striated (Figure 6), the edge of the latch (20) is housed in the teeth during the penetration movement which produces a rack effect. The attachment of the shoe is completed towards the rear of the shoe by the embedding of the head (12) in retrier (13).

The rod (10) and the head (12) are fixed on the shoe by spacers (17) and (18) integral with the carcass of the shoe. Locking is therefore done very easily because it involves a simple movement of the foot back forward, not requiring effort -the resistance of the elastomeric block being negligible- with an intuitive and audible sense of progressive tightening through the rack effect and finally with a visible mechanism and out of snow, ie protected from the frozen snow that usually accumulates on the snowboard and blocks known step-in mechanisms.

MEANS FOR ADJUSTING A DOUBLE SLIDE POSITION

Figures 1, 2 and 5. The bolt (6) which holds the bar (2) on the plate (1) slides longitudinally in the lower slide (8) arranged in the plate (1) at the base (30 ') of its nut (30) and transversely in the upper slide (9) arranged in the bar (2), at the cylinder (30 ") of the same nut, whose circular section also allows any rotational movement of the upper slide. Double sliding allows a free movement of the upper slide on the lower slide and thus both a rotation adjustment, a setting of the transverse position and the longitudinal position on the snowboard.This adjustment is continuous, does not require the stall. of the shoe and offers a travel angle and considerable translation relative to the known fasteners.

POSITION CLAMPING DEVICE (FIGS. 1, 2, mainly 5). The bar (2) is held in position on the plate (1) by the bolt (6) which compresses the two slides by pressing the washer (31) on the upper slide (9) and pulling the lower slide by the foot (30'). The bolt is tightened by the rotation of the eccentric cam lever (33) (33). This type of bolt is known and commonly used in cycling, to fix the wheels for example. The angle of rotation and thus the clamping force is here locked by a second lever (35) fixed in the lever (7) by its axis (37) and one side, notched, is supported by the spring ( 38) on the notched wheel (34) integral with the screw (32) of the bolt (6), which locks the position, regardless of the clamping force. This is necessary because the bolts used in cycling keep their positions only tightly. By pressing on the other end of the lever (35) the user releases its notched end and can change the angle of the lever (7) and the tightening of the position of the bar (2) on the plate (1). Part (D) of Figure 4 shows the levers (7) and (35) in such a configuration. Part (E) shows the underside of the lever (7), in particular its two sides connected by the spacers (39,39 '), and the spring blade (38) bearing on the spacer (39) and the lever (35). The maximum tightening level can be adjusted by the degree of tightening of the screw (32) in the nut (30), which can be performed via the lever (7) is in the loose position.

By positioning the lever (7) on an intermediate clamping angle, the user can change the position of the bindings on the snowboard during the gliding by a effort on the shoes. This possibility opens a way of using snowboard quite new and close to the sea surf.

COMPLEMENTARY ELEMENTS

(Figure 6) The stage is pierced by a series of standard spacing holes called "2x2" allowing additional longitudinal adjustment.

ADVANCED MODEL FOR DEMANDING USER

(Figure 7) This model combines all the solutions to the problems mentioned in the state of the art. It uses two plates (V, V) and anteroposterior attachment on the shoe in order to increase the lever arms between support point and edges and thus maximize the steering precision and power in the support transmissions. Compared to the basic model, the bar (2 ¹ ) has two rails (9 \ 9 ") to accommodate the two levers (TJ"). It is extended by the arms (40,40 ') which carry forward the notched pin (10) and back a notched rod (41) completed with a washer (42). The shoe has at the back two calipers (43,43 ') which are positioned on the rod (41) and block its position on the snowboard to the rear. In front of the shoe is the hooking and locking means described above, but repositioned in the longitudinal direction and fixed by spacers (45 visible to the left, the right spacer is not visible) integral with the carcass of the shoe. The rod (10) is no longer fixed by the spacer (17) the tube (19) is devoid of the notch (not numbered) necessary for its passage and visible in Figure 1 and 3.

The attachment (shown in the inset) is very simply by a movement from front to back which positions the stirrups (43,43 ') on the rod (41) and a small counterclockwise rotation movement sets up the tube (19) on the tip (10) which locks the attachment. Unlocking via the lever (15) as well as changing and clamping the position via the levers (7 ', 7 ") have the same operation as already described for the basic model.

SPECIAL MODELS

BASIC MODEL ADAPTABLE ON ANY FOOTWEAR (Figure 8) The attachment is that of the basic model shown in Figure 1 but the fastening elements on the shoe side are mounted on a removable support that can be attached to any rigid or flexible shoe trade.

The rod (10) and the tip (12) are attached to a spacer (17 ") which extends under the shoe by the spacer (46) forward and the spacer (47) back to receive the straps notched (51) for tightening the 3 straps (48,49,50) by the fixed clamping means (52) and lever (53) around the shoe as shown in the insert. Tightening by strap is known and commonly used in hull type fasteners and therefore does not require further description. SIMPLIFIED BASE MODEL

(Figure 11) This is the basic model of Figure 1 but provided with a single point of attachment in the central position,

ADVANCED MODEL FOR SLIDER SNOWBOARD (Figure 9) Some models of snowboard are known where the inserts intended to receive the screws of the fixings are replaced by slides integrated in the body of the board (eg FR2791268, US6089581). On such a snowboard the plates (1 ', 1 ") of the advanced model can be replaced by two single washers (54,54') MODEL ADVANCE ULTRA LIGHT NOT ADJUSTABLE

(Figure 10) A model of a few tens of grams can be offered to users who no longer wish to change position. Figure 9 shows an advanced model where the bar (2) and platinum (1) are integral at a defined angle and position and are devoid of slides. SAFETY MODEL HAVING A TRIGGERABLE DEVICE

(Figure 12 and 13) The one-sided attachment allows the installation of a releasable device (55) freeing the boot under the effect of rotational or translational forces that could lead to injury. Because unilateral fixation centralizes these forces at a single point, the ease of design and efficiency of this device is enhanced. This device can be of a known type or be the subject of a subsequent patent, its internal structure will not be detailed in this document. Figure 12 shows how to modify the basic model to insert such a device. The anterior (4) and posterior (5) fixing means are no longer connected directly to the bar (2) but via the front (56) and posterior (57) arms to the removable part (55 ") of the safety mechanism ( The fixed part (55 ¹ ) which remains on the snowboard is connected by pentretoise (58) to the bar (2) Figures 12 and 13 show the safety binding before and after its release.

Naturally, the invention is not limited to the embodiments thus described and includes any variant that may fall within the scope of the claims that follow. Among these variants we can for example explain:

- A basic model without the attachment of the type "step-in", that is to say equipped with straps permanently installed on the attachment in a similar manner to the hull type fasteners.

- A triggerable model using two safety devices releasing each attachment means (4,5) separately. - The use of fastening means, locking, clamping, different slide shapes in structure or number of those given here as an example.

In Figure 14 the attachment means - or restraint - consists of a rear gutter (61) retaining the shoe (3) rearward and a front gutter (60) retaining the shoe forward. Each of these two gutters also holds the shoe (3) inwardly and outwardly. The front gutter is movable by its articulation on an axis oriented along an intermediate plane between the longitudinal plane and the transverse plane of the snowboard, so that the attachment can open almost completely on its inner side, the one looking at the other. fixation (Figures 14 and 17).

The locking means (62) is of a known type and is commonly used in ski bindings at the heel. Its function is to maintain two stable positions, open or closed. This is done by an internal spring (not shown) pressing a flat (not shown) integral with the axis (64) and which exerts a strong torque towards closing or opening when a rotation is engaged in one of these directions. The switching between open and closed position is obtained by mobilizing the lever (63). The device is provided with adjustment means for finely adapting the binding to the different shoe sizes and to the preferences of the users:

Thus the rear gutter is adjustable in forward inclination in a conventional manner on this type of gutter, by its articulation at its lower part and each of its sides by means of the axes (67,67 ') integral with the arch (66). The angle of inclination is determined by the adjustable shim (65) which presses the hoop (66).

On the other hand, this rear gutter is secured to the bar (2) by an intermediate piece (68) comprising a slide which receives the hoop (66) via the bolt (69) which allows a translation adjustment in the anteroposterior direction relative to the shoe and therefore the adaptation to different sizes of shoes.

This intermediate piece further comprises a tube (71) in which low the screw (70) which fixed to the bar (2) which adjusts the inclination of the rear gutter in the longitudinal plane of the snowboard. The front gutter (60) is fixed to the locking means (62) by a screw passing through a slot (73) which allows a rotation adjustment in the transverse plane to the snowboard and a vertical translation and thus an adaptation to different sizes and shapes. shoes. OTHER EMBODIMENTS OF GUTTER HOOKING

The attachment may use a different number of gutters, for example two front gutters, a gutter can be located at the toes and stay fixed.

This unilateral type of fixing device makes it possible to have very freely the articulation of the gutters:

- The front gutter can be fixed and the rear gutter articulated by a vertical axis located between the bar (2) and the part (68) and connecting them, the movement of the rear gutter in the horizontal plane opening the attachment to the outside and back.

- The two gutters can be movable and articulated each at the bar (2) and between them at their upper part by the locking means, the combined movement of the gutters fully opening the fixing on the inside, the back and the 'before.

Moreover, the plane of rotation of the joints can vary greatly in all these embodiments.

The locking means may vary, for example: - simple pin type lock, secured to a movable gutter and penetrating into lights integral with the bar (2), blocking this movable gutter in each of the open or closed positions.

- cable operated by a lever, a type similar to that of the old ski bindings, clamping between them and the bar (2) two gutters both hinged, - rotating ratchet with a spring, the spring bringing the binding in the closed or open position and the pawl preventing the reverse rotation, it can be unlocked by a lever.

Furthermore this attachment can be used on other boards gliding for soil or water.

Naturally, the invention is not limited to the embodiments thus described and includes any variant that may fall within the scope of the claims that follow.

Industrial application: like any other snowboard binding, it can be easily produced by industry using standard technologies.
