Description

SKI BINDING COMPRISING AN INTERFACE FIXED TO THE SHOE AND COMING IN A SKI SEAT

The present invention relates to gliding equipment for natural gliding surfaces or surfaces such as snow, water, grass, sand, etc. , consisting of a ski type gliding device provided with detachable connecting means under the effect of accidental stresses between the boot and the gliding device. Such equipment is known.

Indeed, and generally for skiing, it is currently necessary:

- a ski

- fasteners - a specific shoe.

The binding elements are fixed (most often by screwing) to the ski in definitive places determining a given size.

The bindings for equipment rental and hiking are based on the same principle but incorporate a multi-size rear adjustment.

In known equipment, the safety functions are ensured by standards relating to the blocking of the boot and in the event of tripping, the boot is freed from the assembly secured ski / binding.

Currently, on a traditional ski, to satisfy this requirement, the adjustment of the binding cannot be done with respect to the ski without modifying the anchor points. In this case, only a specialist can intervene, which constitutes a constraint.

The device therefore allows adjustment of the binding relative to the boot and not relative to the ski.

Thus, the known equipment has multiple drawbacks related mainly to their complexity and their specificity, that is to say that this equipment is very specialized and practically does not allow versatile use.

The present invention proposes to create a ski equipment of simple construction for the set of boots, bindings and skis, while allowing versatile use, applying to all disciplines of sliding on an element (water, snow, grass, sand, etc.) and will be defined specifically according to the uses, ensuring ^" the link and fixa¬ tion functions between the gliding device and the shoe while ensuring its safety, in the event of a fall, by uncoupling of connecting pieces and making it possible to adjust the binding to the size of the shoe very quickly and simply and regardless of the discipline and the length of the gliding apparatus, the adjustment of each binding covering all the sizes of the To this end, the invention relates to an equipment of the above type, characterized in that it comprises:

A - an interface intended to be fixed in a removable, controlled manner, to the shoe, B - a seat produced in the gliding apparatus for receiving see the interface and allow its uncoupling under the effect of accidental stresses, B, - the seat comprising:

- a front positioning cavity,

5 - a rear positioning part,

- an intermediate positioning member. A-, - the interface comprising:

a front fixing means intended to be housed in the front positioning cavity of the seat, a rear positioning part which can be snapped into the rear positioning part of the seat, a positioning cavity cooperating with a relief positioning member , of corresponding shape protruding into the seat to allow positioning and relative pivo¬ ment of the interface and the seat for accidental uncoupling. 0 In this equipment, the interface is a device for coupling and uncoupling regulated ^¬ ble in dimensions and multidirectional efforts with several degrees of freedom applicable primarily in the ski. 5 This equipment replaces and integrates the functions of all types of ski bindings with or without security as well as those of the walking type known as trekking.

The fundamental advantages of the equipment Q according to the invention are multiple:

The interface provides the binding function with the shoe in its upper part, incorporating the attachment functions fits almost completely into the seat provided in the ski and open on both side faces _c. In the interface, the seat replaces by simple material conformation the essentials of the traditional fixing function. This seat is dormant.

According to the invention, the safety function is no longer provided between the boot and the binding as in traditional skiing, but is provided between the interface and the seat in the beam, the boot and the interface remaining attached.

This safety function is made possible not only only by mechanical means, but also by a specially adapted conformation which falls under the male and female grip principle with pre-tension of materials capable of eliminating the mechanical means. The seat comprises a positioning member, in particular convex but also possibly con¬ cave, in hump or hollow, for axis of rotation and centering of the interface.

According to another characteristic, the seat is of independent dimensions of at least one size class.

This multi-size adjustment is carried out from the front, if necessary adapting to the different thicknesses of the soles. According to another characteristic, the rear positioning part of the interface comprises a lock and the rear positioning part of the seat comprises a cavity capable of receiving the lock as well as a controlled release means enabling the lock to be released by controlling the 'user.

According to another characteristic, the interface has a front element forming an adjustable stop for the fitting of a shoe, corresponding to different sizes. According to another characteristic, the interface this consists of an upper element and a lower element connected to each other by a transverse articulation, front, the lower element being fixed in the seat, the upper element fixed to the shoe being able to be raised relative to the lower element by vertical tilting around the articulation, the two elements being integral with each other 0 by a lock.

- .- According to another characteristic, the seat is provided with an adjustable member making it possible to receive interfaces of different dimensions.

According to another characteristic, the interface is the sole of the shoe.

The characteristics of the invention lead to a new concept of shoe integrating a sole having an interface value, which has become a sole for ski, mountain, boot boots, etc., comprising 0 all the safety, hiking and junction functions. with the seat of the beam.

- This simplifies the interface by abandoning the attachment functions and its thickness will be reduced with prestressing of the materials. 5 This shoe therefore allows walking.

The safety fastener as such and as an independent element is therefore thereby deleted.

In this case, the sole of the boot _Q becomes the base for the construction of the boot, either the shell shell for ski boots of the rigid type, or an overmolding base for the boots of the boot type.

According to another characteristic, the positioning member c is adjustable to receive several interface sizes.

The invention will be described using the accompanying drawings in which: FIG. 1 is an exploded overview of the equipment,

FIG. 2 is a view of the equipment in the assembled state, FIG. 3 is a top view of the interface, FIG. 4 shows a variant embodiment of the interface,

FIGS. 5A, 5B, 5C show an interface which receives three shoes of different sizes,

FIGS. 6A, 6B, 6C show two interfaces for shoes of small size, medium size and large size, FIG. 7 shows the positioning of the interface of FIG. 6B in the seat,

FIG. 8 shows a seat provided with an adjustable positioning organ,

- Figure 9 shows a seat with an inter¬ face and a complementary member.

According to Figure 1 which is a principle diagram of the invention, the gliding equipment consists of three parts, namely a shoe 1, an inter¬ face 2 and a seat 3 made in the gliding apparatus (ski), the latter being shown only for its part corresponding to seat 3.

The shoe 1 comprises an upper part (not shown) and a sole 4 ending in a front end 5 and a rear end 6 forming flanges intended to be fixed in the interface 2.

The interface 2 consists of a body provided with a rear end 7 of complementary shape to the rear end 6 of the shoe 1 for styling and retain it as well as a front end 8 movable in the direction of the double arrow A to allow the introduction of the shoe 1 in the ex¬ front end 8 and the blocking of the shoe by the - closure of the lock 9 which blocks the front end 8.

The interface 2 is intended to be housed in the seat 3 of the gliding apparatus. For this, the interface 2 has a front part 10, at an angle, towards the front and a rear part 11, at an angle, towards the rear 0 as well as a housing 12.

The seat 3 of the interface comprises a front part 13 of shape complementary to the front part 10, a rear part 14 complementary to the shape of the rear part 11 and, a positioning member 15 whose shape corresponds to the positioning housing 12 of the interface.

The interface 2, once fixed to the boot 1, is put in place in the seat 3, ergonomically as in the manner of a conventional ski boot, 0 that is to say that one first engage the front end 10 in the housing 13 and then rock around the front to lower the rear part 11 of the inter¬ face 2 in the rear part 14 of the seat 3, the positioning housing 12 coming to be placed on the positioning organ 15.

To connect the interface 2 to the seat 3, the in¬ terface 2 comprises, at its rear part 11, a latch 16 subjected to the action of a spring 17 pushing the latch 16 in the output position shown in _Q FIG. 1. In a complementary manner, the seat 3 is provided with a cavity 18 of a shape corresponding to the nose of the lock 16 to receive the latter by snap-fastening; the latch 16 is retracted by compressing the spring 17 then is placed in the cavity 18. c To release the interface 2 on command seat 3, the latter is provided with a control member 19 in the form of a lever which, subjected to a push exer¬ ced by the user (for example with the tip of his stick) causes this unlocking member 5 19 to tilt and press the latch 16 in the retracted position per¬ then putting the skier to clear the interface 2 by tilting it in the opposite direction of the engagement.

The different positioning movements are shown diagrammatically in FIG. 1 by the arrows B and C. 10 The assembly position of the gliding equipment is shown diagrammatically in FIG. 2.

The interface adapts to the shoe size and the thickness of the sole and is securely anchored to the edges of the sole,

15 front and rear, by mechanical, automatic, magnetic or other self-locking.

This interface also integrates the mechanical elements allowing at the same time the retention, the triggering as well as the tension regulation. 20 In fact, the interface 2 provides the safety fixing functions by its integrated and tarable load cell mechanism, can be released from the rear (front drop) and in rotation in all directions. 25 Security is obtained by simple rotation and rear unlocking (front fall and side fall) of interface 2.

Safety can also be obtained by unlocking before (rear fall). The rotation of the interface 2 3 _Q is based on the presence of a concave or convex axis of rotation or circular slide located in the seat 3.

Not shown, the sole of the ter¬ 2 is furnished with a fixed or removable surface - _. allowing comfortable and efficient contact with the bearing surfaces: sliding, grip, amortis¬ ment or even the adaptation of crampons, knives.

In general, the seat can be either - * - ^* arranged in the thickness of the machine under the location of the foot, or one or more pieces added (s) and fixed (s) on the machine.

The seat has a prominent positioning member serving as a centering and rotation axis of the movable part and also allowing the evacuation of snow and ice (ski) when booting.

According to a variant not shown, the interface 2 receives, at the front and at the rear, standardized end pieces adapting to traditional fastenings. According to another variant, the interface becomes the sole of a shoe for practicing sliding sports while retaining all the initial functions of the interface, which corresponds to the basis of the design of a generation of shoes. The length adaptation, depending on the pointu¬ re, is integrated either at the interface or at the seat, as described below.

This shoe can be ski boots, mountain boots, boots and ankle boots. FIG. 3 is a simplified top view of the gliding equipment showing the particular shape of the front and rear parts 13, 14 of the seat 3 as well as the corresponding shape of the interface 2. This figure lets appear in dotted lines l 'positioning member 15 and the positioning housing 12 with their axis 20 allowing the pivotal movement of the interface relative to the seat for accidental release. This member 15 is in the form of a truncated cone open on both sides of the parts 15A, 15B for removing snow from the positioning housing. 12.

Figure 4 shows an alternative embodiment of the invention. According to this variant, the interface 2 consists of a lower element 21 intended to come * ^•> in a seat similar to seat 3 of FIG. 1 and of an upper element 22 intended to be fixed to the sole of the shoe 23. The lower element 21 and the upper element 22 are connected by a transverse articulation, allowing a lifting movement of the upper element 22 (and of the shoe 23) by tilting around the axis 24. The two elements 21, 22 are also secured to each other by a lock 25. When the lock 25 is open, the upper element 22 can tilt around the axis 24 (for example for a movement walking, hiking or cross-country skiing) while when the ver¬ rou 25 is closed, the upper element 22 is integral with the lower element 21 and the entire interface 2 behaves like the interface 2 of Figure 1. In both cases, the security functions remain main¬ ten ues.

FIGS. 5, 6, 7 show different cases of positioning the shoe 40, 41, 42 on the interface 2 along the sizes of the shoes 40, 41, 42. The shoe 40 is of relatively small size, the shoe 41 of medium size and shoe 42 of large size. Depending on the case, the rear end of the shoes 40-42 is always in abutment at the rear in the same position while the front part of the shoe is more or less advanced. Figures 5A, 5B, 5C.

Figures 6A, 6B, 6C show two alternative embodiments of the interface.

Figure 6A shows the medium-sized interface while Figures 6B and 6C show a 11 interface provided with a front end 43, adjustable sui¬ vant the dimensions of the seat 3. This front end can come in the advanced position as shown in Figure 6B or in the retracted position as shown in Figure 6C.

FIG. 7 shows the positioning of the interface 2 ′ adjusted as indicated in FIG. 6B and placed in a seat 3.

FIG. 8 shows another variant of the invention, according to which the positioning member 15 ′ of the seat 3 is removably placed in this seat so as to be able to occupy either the position 15 ′ shown in FIG. 10, or the position 15 "shown in dotted lines. This also allows adaptation to an interface of different size corresponding to two types of sizes.

Figure 9 shows another variant of the invention. According to this variant, the seat 3 has a usual dimension while the interface 2 "has a reduced dimension. The front part of the seat 3 is then occupied by an adapter shim 3 ′ which makes it possible to reduce the length of the seat 3.

According to the invention, the seat 3 is produced directly in the ski and the same applies to the positioning member located in the seat.

According to a variant, the interfaces of two skis can receive connecting members solidari¬ sant the interfaces or the skis and, as a result, the two skis 7 become a monoski. In summary, the gliding equipment according to the invention is based on the following points:

- A principle of male and female parts which are integrated by simple interlocking ensuring the connection functions. - the safety function is based on a principle centered or non-interactive axial pipe with different tarable mechanisms or not or with prestressing of materials.

The interface seat contains all the control elements for all the functions of the interface.

These control elements operate by simple pressure or sensitive pulse.

It should be noted that the locking of the interface in the seat is ensured by at least one lock. This lock can be at the front or at the back. It can also be several locks repaired.

A reverse connection, that is to say by latches integrated in the seat, is also possible without departing from the scope of the invention.

The expressions "lock" and "cavity" used above and illustrated in a particular case correspond to general functions that can be carried out, for example, for prestressing the material.
