Description

DEVICE FOR ADJUSTING THE FIXATION OF SHOES ON A SNOW SURFBOARD

The present invention relates to a device for adjusting the binding of shoes on a snowboard.

Currently, the bindings essentially consist, for a rigid shoe, of a sole provided with two stirrups, one at the front and one at the rear, the ground idarization to the surfboard being produced by means of screws, generally six, on the one hand to fix said sole in a precise angular position and on the other hand to adjust the spacing of the stirrups according to the size of the user.

In the case of a flexible shoe, the stirrups are replaced by straps which can be tightened at will. If the current bindings do not present a disadvantage for the owners of surfboards which, in the majority of the cases regulate them once and for all, it is not the same for the renters of surfboards who must adapt the material to the requirements of their customers, which requires for each plank the removal and installation of a large number of screws.

The object of the present invention is to remedy this drawback by proposing a device for adjusting the angular position and the size of the binding of the boots on a snowboard, which is easy and quick to use.

The device which is the subject of the present invention is essentially characterized in that it comprises on the one hand a frame to which the means of attachment to the shoe are attached; and on the other hand a round and flat piece fixedly fixed flat on the surfboard, and having a peripheral rebate below creating with said board a peripheral groove in which are engaged at least partially, on either side of said piece , the longitudinal sides of the frame, so that it is movable in rotation and in translation by relative to said part which comprises blocking means making it possible to secure said frame to the board in the desired longitudinal and angular positions.

According to a first embodiment of the device according to the invention, the frame is extensible and for this purpose comprises two U-shaped parts sliding mounted one inside the other, and the round and flat part comprises on its cylindrical wall radial bores in one of which, as desired according to the desired angular position, is introduced, of the desired length, and locked, an axis perpendicular to the transverse part of one of the U-shaped parts of the frame.

According to a variant of this first embodiment of the device according to the invention, the axis is a threaded rod and the radial bores of the round and flat part are tapped, the ground idarization of said threaded rod to the transverse part of the part U-shaped frame being made in translation but not in rotation.

According to a second embodiment of the device according to the invention, on the one hand the round and flat part has teeth on its cylindrical wall; on the other hand, the frame, consisting of two U-shaped parts mounted to slide one inside the other, internally comprises teeth capable of meshing with said teeth of said round and flat part; and on the other hand, said frame comprises an adjustable transverse flange making it possible to control the spacing of the branches of the U-shaped parts forming said frame.

According to an additional characteristic of this second embodiment of the device according to the invention, the parallel branches of one of the U-shaped pieces forming the frame are of U-shaped cross section, and the parallel branches of the other U-shaped piece, which slide in said branches of U-shaped section, have the teeth on their internal face.

According to a variant of this second mode of embodiment of the device according to the invention, a branch of each of the U-shaped pieces forming the frame internally has teeth, and said U-shaped pieces are assembled so that the toothed faces of said branches are facing each other, the non-toothed branches of said pieces in U comprising at the end a ring allowing them to be fixed, with the possibility of sliding, to the adjacent toothed branch.

According to a third embodiment of the device according to the invention, used for fixing a flexible shoe, the frame comprises a U-shaped part intended to wrap said shoe laterally and posteriorly, whose parallel branches are connected by their ends by means of at least one strap intended for tightening the front part of the shoe; said frame internally comprises teeth intended to fit onto the round and flat part which for this purpose comprises teeth on the periphery, an operable flange, positioned transversely behind said teeth making it possible to control the transverse deformation of the frame; the fixing of the shoe at the ankle being carried out by means of a heel-piece placed under the heel of the shoe and secured to the latter by means of a strap, said heel-piece having laterally two extensions going up on either side of the shoe and comprising externally transverse notches intended to be embedded in longitudinal notches which comprises the U-shaped part of the frame, between its curved rear part and said flange. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents several non-limiting embodiments. In the attached drawing:

- Figure 1 shows a plan view of a first embodiment of the device according to the invention.

- Figure 2 shows a partial view in cross section along the axis XX 'of Figure 1.

- Figure 3 shows a plan view of a second embodiment of the device according

1 invention.

FIG. 4a represents a partial view in cross section along the axis YY ′ of FIG. 3.

- Figure 4b shows a partial cross-sectional view of a variant of this embodiment.

- Figure 5 shows a side view of a third embodiment of the device according to the invention.

- Figure 6 shows a partial plan view of the same device.

Referring to FIG. 1, it can be seen that in a first embodiment, the device according to the invention comprises a rectangular frame 1 produced by the assembly of two parts 2 and 3 in the shape of a U, the parallel branches 20 and 21 of the part 2 being slidably mounted each in one of the tubular branches, respectively 30 and 31, of the part 3.

To each of the transverse parts 22 and 32 of the parts, respectively 2 and 3, is fixed a stirrup, respectively 10 and 11, the sliding of the part 2 in the part 3 making it possible to adjust the spacing of the stirrups 10 and 11 as a function the size of the user.

If we also refer to Figure 2, we can see that the branches 30 and 31 of the piece 3 are engaged on either side of a round and flat piece 4 secured to the surfboard 5 by means of screws 42. The part 4 has a peripheral rebate 41 creating with the board 5 a groove 40 in which the branches 30 and 31 take place. The part 4 has in its cylindrical wall a series of tapped radial bores 43 regularly distributed, in one of which is screwed a screw 6, also screwed perpendicularly in a lug 33 transversely connecting the ends of the branches 30 and 31 of the part 3, and secured, in translation but not in rotation, to the transverse part 22 of the part 2, this idarization ground being produced by means of a non-threaded part 60 below the head 61, and of a nut 62 and a lock nut 63.

The angular adjustment is carried out by introducing the screw 6 into the corresponding tapped bore 43, the depth of the screwing making it possible to adjust the spacing of the stirrups 10 and 11.

It should be noted that the screws 42 of the floor idarization to the board 5 are introduced into oblong orifices 44, which makes it possible to refine the angular adjustment.

It should also be noted that in a variant the screw 6 is replaced by a rod capable of being introduced into one of the radial orifices 43 which do not need to be tapped, the blocking of said rod being achieved by appropriate means.

If we now refer to Figure 3 we can see that in a second embodiment of the device according to the invention, the branches 30 and 31 of the part 3 are of U-section, that the branches 20 and 21 of the part 2 have teeth 23 internally, and that the part 4 peripherally comprises teeth 45.

If one also refers to FIG. 4a, it can be seen that the lateral wings 34 and 35 of the branches 30 and 31 pass respectively above and below the part 4, which has a peripheral rebate 46 for this purpose below, so that that part 3 is linked to part 4.

The branches 20 and 21 of the part 2 are each threaded in one of the branches, respectively 30 and 31, and are interposed between these and the part 4, their teeth 23 meshing with the teeth 45 of the part 4. The ends of the branches 30 and 31 are connected transversely by a flange 36 making it possible to maintain their spacing and therefore to clamp the branches 20 and 21 on the part 4. The flange 36 can be loosened by means of a cam 37 which can be operated by a handle 38, the adjustment being able to be refined by means of a screw 39.

The opening of the flange 36 allows the branches 30 and 31, and 20 and 21 to be separated, and thus the disengagement of the teeth 23 from the teeth 45, which allows the pivoting of the frame 1 on the part 4 and the bringing together or

1 distance from the stirrups 10 and 11.

In FIG. 4b it can be seen that in a variant the branches 20 and 21 of the part 2 which slide in the branches respectively 30 and 31 of the part 3, are also of U-shaped section, so that they each have wings upper and lower, respectively

24 and 25, passing above and below the part 4, the wings 25 and 35 being engaged in the rebate 46, and their extreme edge comprising teeth, respectively 25 'and

35 ', intended to mesh with teeth 47 that peripherally comprises the part 4 in the bottom of the rebate 46.

If we now refer to Figures 5 and 6 we can see that in a third embodiment of the device according to the invention, it comprises, as in the previous embodiment, a round and flat piece 4 secured to the board , not shown, and comprising at the periphery of the teeth 45 and below a rebate 46.

The frame 1, made in a single piece, comprises two separate parts, a substantially flat part 7 intended for the floor idarization to the part 4, and a part 8 intended for the fixing of the shoe 9, which is flexible.

Part 7 is approximately U-shaped, it has _. centrally, between two longitudinal sides

70 and 71, a recess 72 bordered laterally, on the one hand, lower edges 73 intended to take place under the rebate 46, and secondly, upper teeth 74 intended to mesh with the teeth 45.

The rim 73 and the teeth 74 are arranged in a non-coaxial two non-coaxial circles, offset in the longitudinal direction, thus defining two different positions for securing to the part 4.

The positioning of part 7 is carried out by deforming it transversely, and its maintenance is carried out by means of a transverse flange 75, provided with a cam 76 which can be operated by means of a lever 77.

In a variant, the part 4 does not have a rebate, it is of frustoconical shape and widens upwards, its inclined wall is toothed, and the internal toothed edge of the frame is then of complementary shape.

Part 8 is U-shaped and protrudes above part 7, that is to say that it has a curved rear part 80 and two lateral branches 81 so that shoe 9 can be fitted therein, heel 90 taking place in the curved part 80.

The front 91 of the shoe 9 is fixed by means of a strap 82 connecting the ends 83 of the lateral branches 81, and passing over the shoe 9. It should be noted that the strap 82 can furthermore, by a deflection device not shown, also pass in front of the shoe 9, in order to properly wedge the heel 90 in the curved part 80.

The shoe 9 is also fixed by means of a heel 84 intended to be placed under the heel 90 which it partially envelops and to which it is held by means of a strap 85 passing over the ankle 92 .

The heel 84 has laterally two extensions 86, only one of which is visible in FIG. 5, rising on either side of the shoe 9 internally to the part 8 of the frame 1, and comprising externally transverse notches 87 intended to be embedded in longitudinal notches 88, visible in FIG. 6, which internally comprises the part 8 between the flange 75 and the curved part 80.

In practice, the strap 85 is tightened on the shoe 9, the part 7 is secured to the part 4 by means of the flange 75 which is not completely closed, then the shoe is placed in the part 8, the strap 82 is tightened, finally the flange 83 is closed to maintain the notches 87 in the notches 88.

It should be noted that the attachment of the shoe 9 at the ankle can also be carried out in a conventional manner by means of a strap secured to the part 8 of the frame 1.
