The first binding element has two parallel side jaws (7') spaced apart by the width of the boot's sole and at right angles to the surface of the snow-board. Each side-jaw has an opening (8) in for a pin. The side jaws of the second binding element have surfaces (10) sloping down towards the front bracket (4). The boot has protuberances (11) staggered towards the boot's toe and spaced apart from the pins. <IMAGE>

Description

The invention relates to a snowboard binding with snowboard boots according to the preamble of claim 1. Such Binding was made public at ISPO in Munich on February 24, 1994 issued. This bond had a firm bond with him Snowboard connected front bar, which is the front part of the Boot sole overlapped and celebrated. Through the heel side Part of the sole of the boot was a cross to the longitudinal axis of the boot running bolt inserted, the on both sides protruded about 5 to 10 mm from the sole of the boot. A Heel element to be firmly screwed to the snowboard consisted of two parallel and perpendicular sidewalls protruding from the snowboard surface, which had a vertical elongated hole in which the part of the stud protruding from the side of the shoe could be introduced. A locking device on the side cheeks had the shape of a hook that when inserted the bolt was pushed back into the elongated holes and these with it opened while being completely in the oblong holes received bolt parts by spring force in a locking position snapped and locked the bolts. A lever on one of the side bolsters was required to open the binding are operated, causing the bracket to be in the open position were brought and the heel part of the shoe could be removed from the binding. This on the Binding issued by ISPO is also in the post-published DE 43 11 630 A1 described.

The US 4,640,026 shows a ski binding with conventional Binding jaws. The binding has a first on one Ski fastened binding jaw on that with a swivel binding element attached in the heel area of a boot interacts, that with closed binding in the cheek snaps into place and is integrated into the sole of the boot spring-loaded pin is locked. About one too electromagnet integrated into the boot, which by electrical signals can be controlled by the on the boot attached force transducers will be delivered Pen moved and the binding opens automatically as soon as specified forces are exceeded.

AT-PS 351 419 shows a ski binding with one of the boots of the driver almost completely enveloping, hinged Shell that is firmly attached to the surface of the ski. One the forefoot and one the front of the shin covering shell parts are pivotable on the front Tip of the bowl hinged and can be between one Open or entry position and a closed position be pivoted. In the closed position, these are both shell parts mentioned by spring-loaded locking pins locked on the fixed shell parts. The spring-loaded bolts can be pulled into a cable Unlocked position to be triggered binding in the event of overload or opening of the binding allow to get out. In the latter case, the Driver pulls the cables through a fixed shell part Operate the attached lever. So here it is around a shell binding that the use of very soft and should enable comfortable ski boots.

DE 25 56 817 A1 shows a ski binding with a binding plate, the surface by spring-loaded cables the ski is attached. If one is exceeded This plate can be triggered by a length of the cable pulls predetermined distance from the surface of the Remove skis. There is a recess in the sole of the ski boot intended for this plate. Inside the plate there is a locking mechanism that has a lock the plate in the recess of the ski boot sole. If the binding is released in the event of overload So the boot and plate from the ski, but only as far as the cables allow. To open, i.e. To get out, the boot must be detached from the plate. For this purpose, an unlocking mechanism is provided on the plate, by the driver by hand or with the ski pole can be operated.

Another so-called "step-in" binding in which the driver no locking elements when entering the binding must be operated by hand is described in DE 41 06 401 A1. The boot is supported by two common straps, i.e. one Front and one heel strap held. The heel strap is, however, articulated on an appearance element, the in turn swiveling on firmly connected to the snowboard Binding parts is attached. There is also a locking mechanism attached, when fully depressed Appearance element grabs this and in its Keeps position locked. To open the binding must the driver stoop down and this locking mechanism from Use your hand to open the binding. If under the shoe sole is snow or ice, is also a locking of the tread element not ensured because first this snow or ice to rest on the binding would come before the tread element is fully depressed is. This binding is only partially functional.

DE 25 11 332 A1 shows a ski binding in which also part of the binding integrated into the heel of the ski boot is. Two spring-loaded pins with a spherical head protrude sideways out of the heel part of the boot sole and rest in counter shots, the side of the boot sole are firmly attached to the ski. This is about It's a self-triggering security tie that then opens when a predetermined force is exceeded becomes. This force is applied by the two bolts outside pressing spring determined, as well as by the shape of the Ball heads of these bolts and the shape of the receptacle for these ball heads.

The regular opening of the binding takes place at the tip of the boot holding toe cheeks while heel attachment can only be opened in that the spring force by edging of the boot is overcome. For emergencies where the Should the driver be injured, it is still envisaged that the the ball heads of the bolt-receiving elements are rotated so that an existing groove allows that the boots are pulled up out of the binding can.

Another trigger binding for skis is in the DE 22 00 056 A1 described. There is a straight through there too the sole of the boot is provided with bolts that are in one hook-shaped, spring-loaded locking element snaps into place. The entire locking element is used to open the binding pushed backwards in the longitudinal direction of the ski, which is achieved by operating a lever attached to the ski becomes.

DE 31 41 425 A1 shows a safety binding for skis, with the spring-loaded pin on the boot and Appropriate cradles are attached to the ski. Here, too, a ski is attached to open the binding Mechanism operated.

Finally, DE 28 09 018 A1 shows a ski binding system consisting of ski boot and trigger binding parts, on the sole of the boot a side over the sole contour protruding plate is recessed or two in the distance to each other bolts and provided on the ski swivel hook are this plate or the two bolts laterally spread.

For snowboard bindings it has long been a wish of many Driver to have a so-called "step-in" binding, i.e. a binding in which you can easily do similar to ski bindings can get in without the driver bending down must wzb to parts of the bond. Activate locking bracket. On the other hand, self-triggering bindings on snowboards, which in the event of excessive force on the The driver's foot releases the shoe completely Allow snowboarding, still problematic, because despite numerous Proposals the resulting security problems not yet satisfactory for the driver or third parties are solved. Finally it turns out with snowboard bindings still the serious space problem. The snowboarder stands essentially perpendicular to the direction of travel the snowboard, which in practice means that the angle between the longitudinal axis of the shoe and the longitudinal axis of the snowboard is between 45 ° and 90 °, with some drivers too even back your foot towards the direction of travel, i.e. with an angle of over 90 °. Because snowboards and especially the so-called alpine boards for piste skiers The toe and heel protrude ever narrower of the boot already today over the contour of the snowboard out. Basically, it should be noted that a Snowboard binding not over the toe or the The heel of the boot may protrude as this will result would that outstanding binding parts when edging the Snowboards touch the snow. This is why the usual ski bindings that have the "step-in" function, not suitable for snowboards.

The aforementioned, published at ISPO in February 1994 Avoids "step-in" binding for snowboards these disadvantages; however, their ease of use still leaves Desires open, as the driver to open the binding must bend down to get one directly on the board surface to operate the release lever. The construction is also this release lever is technically complex and weight increasing. This runs the trend towards the lightest possible Snowboards and snowboard bindings.

The object of the invention is therefore the snowboard binding of the type mentioned to improve in that the comfort of the binding is further improved and the Still bind the requirements for low weight, Functional reliability and the lowest possible costs met.

This object is achieved by the specified in claim 1 Features resolved. Advantageous refinements and developments the invention can be found in the subclaims.

Die am Snowboard zu befestigenden Bindungsteile sind leicht und kostengünstig und gegen Vereisung unempfindlich. Die teureren und gegen Vereisung empfindlicheren Verriegelungsteile befinden sich im Inneren des Stiefels bzw. der Stiefelsohle, sind daher gegen Vereisung besser geschützt und können mit anderen Snowboards, die die gleichen Bindungsteile aufweisen, kombiniert werden. Ein wesentlicher Aspekt der Erfindung liegt darin, daß nicht nur das Einsteigen sondern auch das Aussteigen aus der Bindung wesentlich erleichtert ist, also auch die sog. "Step-out-Funktion" realisiert ist. Schließlich ist auch noch besonders hervorzuheben, daß die Bindung nach dem Öffnen automatisch in ihre Ausgangsstellung zurückgeht und ohne weitere aktive Mitwirkung des Fahrers für ein erneutes Einsteigen bereit ist. Diese Ausgangsstellung ist gleichbedeutend mit der Schließstellung, d.h. die Verriegelungselemente haben sowohl bei vollständig geöffneter als auch vollständig geschlossener Bindung dieselbe Ruhelage. Somit kann es in der Praxis nicht vorkommen, daß die Verriegelungseinrichtung in einer Position verbleibt, beispielsweise durch Vereisung, bei der die Bindung sich ungewollt öffnen würde.

The main idea of the invention is therefore to move essential parts of the binding and in particular the locking device in the snowboard boots, which not only improves the comfort when exiting the binding, that the driver no longer has to bend down to the snowboard but also The following additional advantages can be achieved:

The binding parts to be attached to the snowboard are light and inexpensive and are not sensitive to icing. The more expensive locking parts, which are more sensitive to icing, are located inside the boot or the sole of the boot, so they are better protected against icing and can be combined with other snowboards that have the same binding parts. An essential aspect of the invention lies in the fact that not only getting in but also getting out of the binding is made considerably easier, so that the so-called "step-out function" is also realized. Finally, it should also be particularly emphasized that the binding automatically returns to its starting position after opening and is ready for a new entry without further active participation of the driver. This starting position is synonymous with the closed position, ie the locking elements have the same rest position both when the binding is fully open and when it is completely closed. Thus, in practice it cannot happen that the locking device remains in a position, for example due to icing, in which the binding would open unintentionally.

Further advantages of the invention are as follows Description explained.

The same reference numerals in individual figures denote the same or functionally corresponding parts.

Although the invention is in most embodiments (with the exception of Fig. 7) in connection with the use a front bracket is described, it should be noted that the invention in all embodiments without can also work without such a front bar. In in this case, the shoe-side binding part - as in 14 described in more detail in connection with FIG is attached - about in the middle of the shoe and it is ensured by pad blocks that the Sole tip and heel opposite at correct height the snowboard surface. In this case, too a binding baseplate can be omitted. If however, the fixation of the snowboard-side binding part be extensively changeable on the snowboard should, for example to set the step size between the two bonds and / or the angle of rotation of the Binding in relation to the longitudinal axis of the snowboard, see above you will also use a base plate with this variant.

In Fig. 1, a snowboard boot 1 is in side view see the one shortly before its locking position is to be attached to the snowboard -S- binding element 2. This binding element 2 consists of a base plate 3, which is to be attached to the snowboard, which is due to diverse, known way can happen. As with so-called plate bindings Usually, the binding element has a front bar 4 on which a sole protrusion 5 of the snowboard boot 1 overlaps and thus the front end of the snowboard boot fixed. A second binding element 6, here as a heel part 6 of the snowboard boot 1 is formed essential parts of the bond with one on the binding element 2 attached heel element 7 cooperate.

Roughly sketched, this heel element 7 has two parallel, Sidewalls 7 'and perpendicular to the base plate 3 7 '', whose distance is only slightly larger than the width of the heel part 6 of the snowboard boot 1. Both side cheeks 7 'and 7' 'each have an opening 8, in each a spring-loaded pin 9, which laterally from the heel part 6 protrudes, can snap into place.

To securely fix the snowboard boot, it is necessary that he is facing forward with a minimum force the front bracket 4 is pressed. So this means that the distance between the front bracket 4 and the pin 9th or the opening 8 receiving this a certain maximum length has to apply this power. While entering The boot is usually lowered into the binding Pointed and slightly raised heel forward against the Front bracket 4 pushed, but not enough Contact force is generated. With that then one Lowering the heel, the pin 9 and the openings 8 still not properly aligned. To achieve this, is a sloping slope on the side cheeks 7 'and 7' ' 10 provided, which project laterally on the boot Projections 11 cooperate and when pressed down the heel push the boot forward overall. Of the Distance between the pin 9 and the projection 11 corresponds exactly the distance between the opening 8 and the Slant 10, so that the spring-biased when pressing the heel Pin 9 guided past opening 8 with certainty and can then snap into it. At the same time becomes the necessary force pushing the boot forward generated that the boot tip sufficiently firm against the Front bar 4 presses.

When the pins 9 are snapped into the openings 8, the boot is firmly attached to the snowboard and can involuntarily no longer come loose. To open the binding in this embodiment, the two pins 9 pressed towards one another towards the inside or pulled so that they come out of the openings 8, whereupon the shoe first raised at the heel and then removed from the binding can be. To the pin 9 in the manner described to move, a rope 12 is provided on the Back of the boot 1 is led up to the shaft and is held there with a strap 13. At the end of the rope 12, a grip loop 14 is attached. Will on the rope 12 are drawn, as in connection with the following Description becomes clearer, the two bolts 9 pulled inwards, which opens the binding.

A special feature of the invention is that The binding is opened and unlocked on the boot and not - as with the previously known snowboard or ski bindings - on the part of the binding that is connected to the snowboard or the ski is fixed. Among other things, this has the advantage that the driver doesn't bend down to the binding must or - like most ski bindings - snowboarding Ski poles that are not available anyway to help must take. The driver can also use the rope if desired Extend any 12, for example up to the amount of Belt. Another advantage is that essential Components of the binding are integrated in the boot. In order to can be the binding element permanently connected to the snowboard 2 be of a very simple design and therefore also very inexpensive, so that a rider who owns multiple snowboards only once the more expensive binding parts together with the Must buy boots, while for all snowboards only that cheaper binding element 2 must be bought.

It should also be emphasized that the heel part 6, the essential Contains components of the binding, also as a separate part manufactured and subsequently screwed onto a boot, glued or attached to it in any other way can.

Fig. 2 shows a side view of the heel-side components the binding in the locked state, that is the pin 9 is engaged in the opening 8. Here is also clearly the effect of the slope 10 and the projection 11 to see the interaction of the boots in the Depress the heel so that the pin 9 and the opening 8 are aligned with each other. From Fig. 2 can be seen better that the side cheek 7 on one on the base plate 3 fixed holding block 15 slidably is guided, whereby the binding as a whole to the shoe size can be adjusted. For moving the side cheeks an adjusting screw 16 is provided.

The side cheeks have a hollow at their upper end 17, which makes it easier to get into the binding by namely the pin 9 with light pressure on the heel deepest point of the trough 17, with which the Projection 11 in the correct position with respect to the slope 10 is. It can also be clearly seen from FIG. 2 that the bottom of the sole of the heel when locked Binding not yet on any binding elements wzb. the holding block 15 rests, but a distance adheres to this. This ensures that the Binding also takes place when there is snow under the sole of the boot is. Because the heel of snowboards is a bit higher anyway supposed to be the tip of the boot, you can look at the invention the otherwise used wheel chocks for the heel part save the bond.

3, the position of the two side cheeks 7 'and 7' ' to recognize the parallel to each other perpendicular from the Stand off the snowboard surface and the heel part between them of the snowboard boot. Both side cheeks 7 ' and 7 ″ are connected to one another by a connecting element 18 connected, which rests on the holding block 15. Both sidewalls 7 'and 7' 'are towards the base plate 3 extended beyond the connecting element 18 and overlap the holding block 15 with one another on the inside to directed legs 19 'and 19' '. This is the heel element 7 firmly guided on the holding block 15 and can only be moved in the longitudinal direction of the snowboard. For this the holding block 15 has an opening 20 for receiving the Adjusting screw 16 and an elongated hole (not shown), the opening 20 to the top of the holding block 15 opens, so that a not shown, with the connecting element 18 connected threaded part with the adjusting screw 16 is connected, with which a longitudinal adjustment of the heel element 7 is possible.

3 that the side cheeks are clearly visible 7 'and 7' 'above the openings 8, a slope 21' or 21 '', which ensures that the spring-loaded Pin pressed into the heel part 6 of the shoe becomes.

To make the trough 17 even more efficient, it is appropriate to ensure that the bolts 9 only in the position they are in lowest point of the trough. Otherwise they should join its cylindrical part at the top of the side cheeks lie on. For this purpose, in the area of the slopes 21 'and 21' ' a parallel to the longitudinal extent of the side cheeks 7 ' and 7 '' extending further trough 22 provided on can best be seen from FIG. 3a and a larger angle of inclination versus one perpendicular to the snowboard has standing central axis 23 as the slope 21 '. Only when the bolt 9 lies in the lowest point of the depression 17 its free end lies against the wall of the trough 22, so that when the heel is pressed down, it is pressed inwards becomes.

From Fig. 3 it can be seen that the central axis 24 of the openings 8 at a distance from the top of the connecting element 18 lies, this distance being larger is the corresponding distance between the center point of the pin 8 and the underside of the sole of the heel part 6 of the snowboard boot 1. The function of the Binding through snow or ice on the sole of the snowboard boot not affected.

Fig. 4 shows a plan view of the interior of the heel part 6 of the snowboard boot 1. This heel part has one Cavity 25 in which the pins 9 and 9 'and the mechanism for moving the same. The heel part 6 has two opposite one another along an axis 26, according to when the binding is locked to the axis 24 Fig. 3 coincides, aligned openings in the Guide bushings 27 and 27 'are used and in which the pins 9 and 9 'along the axis 26 slidably guided are. Both pins are turned outwards by a spring 28 pressed until the here in the embodiment of FIG on the inside end faces of the pins 9 and 9 ' push directly attached spring 28 against a stop, which is formed here by the guide bushes 27.

The spring 28 is designed here as a U-shaped bracket. The length of the pin 9 and 9 'is such that the Pins 9 and 9 'only by a predetermined amount, for example 5 to 10 mm laterally from the contour of the heel part 6 step out. The outwardly projecting ends of the pins 9 and 9 'are rounded to prevent the insertion of the pin between to facilitate the two side cheeks 7 'and 7' '. The radius of curvature of these roundings is preferably equal to half the diameter of the otherwise cylindrical Tenon so that the outwardly protruding tip of the tenon form a hemisphere.

To open the binding is on both pins 9 and 9 ' a traction member 29 or 29 'attached, the simplest Case can be a plastic or steel rope. These two Tension members are in opposite directions via a deflecting post 30 guided and in a connecting element 31 with each other and connected to the leash 12 through an opening 32 is led out of the interior of the heel part 6, as shown in detail in Fig. 1. The rope 12 too can be a plastic or steel cable. Will on this Rope 12 pulled, so the tensile force on the two Tension members 29 and 29 'passed and through the deflection post 30 transferred to the pins 9 and 9 ', so that these lengthways the axis 26 drawn into the heel part 6 become. This will release the bond. Will the rope 12 loosened again, so the two pins by the Spring 28 pushed out again.

From Fig. 4 it can also be clearly seen that the projections 11 and 11 'approximately the same distance as the pins 9 and 9' emerge the contour of the heel element 6, whereby the pins 9 and 9 'are also shielded so that the Danger of getting caught on the cones during normal walking, is reduced. For this purpose, the projections 11 and 11 ' also a rounded shape, for example an ellipse shape and thus act as deflectors that prevent the Pins 9 and 9 'get caught on any objects. The surface 33 directly facing the pin 9 and 9 ' or 33 'of the projections 11 or 11' is essentially just trained and adapted to the slope 10 (Fig. 1).

Finally, in Fig. 4 it can also be seen that the heel part 6 is closed all around and therefore also as a retrofit part can be used for conventional snowboard boots can. Of course it is also possible to use the heel part 6 completely into the shell of the snowboard boot integrate.

The side view of FIG. 5 illustrates the location of the Spring 28, the traction elements 29 and the rope 12 in the heel part 6 of the snowboard boot 1. The deflecting post 30 can as separate part can be provided, but it can also be in one piece with the heel part usually made of plastic be injected.

Fig. 6 shows another variant of the heel part, the differ from the embodiment of Figures 4 and 5 distinguishes the spring and the traction elements. The spring 28 is designed here as a spiral spring, which is along the axis 26 is aligned and against the two pins 9 and 9 ' presses. Both pins 9 and 9 'have one at each end Widening 33 or 33 'on which the spring 28 is supported and additionally one arm of a lever 34 or 34 ', on the side opposite the spring 28 the widening 33 supports. This can be done unilaterally. The corresponding lever arms can also be used as a claw be formed, overlap the pin on both sides. This Arms are curved convexly when pivoting the levers around a pivot axis 35 or 35 'along the widening 33 to slide. The other two arms of levers 34 and 34 ' are approximately at right angles to the arms mentioned and are connected to the rope 12 via two short ropes 36 and 36 '. In the illustration in FIG. 6, the rope 12 is currently being pulled so that the two pins 9 and 9 'substantially are in the unlocked position. In the locked Position beat the arms 34 and 34 'on the guide bushings 27 or 27 'on, which in turn the limit position of the pin 9 and 9 'is defined.

The variant of FIG. 7 also works with a spiral spring 28 and levers 34 and 34 '. It is different of the embodiment of FIG. 6 essentially only by the shape of the levers and their attachment to the Pins 9 and 9 '. The levers 34 and 34 'are here connected to the pin via an elongated hole connection, i.e. the levers 34 and 34 'each have an elongated hole 37 or 37 'into which a pin 9 perpendicular to the axis 26 and 9 'extending bolt 37 is inserted. When panning the lever slides this pin 37 'along the elongated hole 37. Otherwise, the mode of operation corresponds to the exemplary embodiment 6.

The embodiment of FIG. 8 also works with a coil spring 28 and a linkage, the result exerts the desired tensile force on the pins 9 and 9 '. The pins 9 and 9 'are bent, so that the bent Arms 38 and 38 'are offset from axis 26. The free ends of these cranked arms 38 and 38 'are over Slot connections 39 and 39 'with a swivel lever 40 connected, the pivot axis 41 mirror symmetry to the two pins 9 and 9 'on the axis 26. The Rope 12 can either be at one end of the pivot lever 40 be articulated or - depending on the desired exit point - for the rope 12 on a further pivot lever 42, the is firmly connected to the pivot lever 40 and thus the Tractive force of the rope 12 transfers to this.

In the embodiment of FIG. 9, the inside of the second binding part 6 lying portions of the pin laterally offset from each other and are also here a spring, not shown, pressed outwards. The overlapping parts 42 of the pins have through openings 43 with bevelled sides 44. In these Through holes a bolt 45 is inserted, the opposing run-up slopes 46 and 47. Will the Bolt 45, which is connected to the cable 22, displaced, so the two pins 9 and 9 'are pulled inwards, which opens the bond. The spring that the two pins 9 and 9 'effectively pushes outwards, can on the be implemented in various ways. For example can it directly on the bolt 45 in extension of Attack the central axis and take the form of a compression or tension spring be. It can also be used as a bow spring the embodiment of FIG. 4 be configured.

Finally, one or two compression springs can also be provided be that act directly on the cones.

10 and 11 are a or two pins attached to the side cheeks 7 'and 7' ', while the locking mechanism is in the shape of a or has two pivoting levers, the or the pin reach behind.

10A shows a side view of the heel part 6 of a Snowboard boots 1. In the rear sole area an inwardly recessed recess on both sides 48 provided in the pointing towards the boot tip Area has a slope 49 that is near the bottom 50 of the sole ends with a curve 51. In these two Recesses 48 is a locking lever 52, 52 'housed, both locking levers 52 and 52 'are attached to a common rotary shaft 53. This The rotary shaft extends across the snowboard boot through the cavity 25. There is another on the rotary shaft 53 Lever 54 rotatably attached, which is connected to the rope 12 is. Furthermore, a lever, not shown, can be on this lever 54 Be attached to the spring against the direction of pull Rope 12 the lever 54 and thus the two locking levers 52 and 52 'in the direction of the tip of the boot and thus the locking lever in its locking position. The locking levers 52 are curved in an arc and have a flat locking surface 55, which in locked position is aligned approximately horizontally and the assigned, firmly on the side cheeks 7 'or 7 '' attached pin 9 or 9 'contacted. Adjacent the locking lever points to this locking surface 55 52 has a run-up slope 56, which when entering the Binding ensures that the locking lever 52 and 52 'are pivoted backwards into the open position, as soon as the ramp slope 56 touches the pin 9. As soon as the tip of the locking lever slid past the pin 9 is, the locking lever 52 by the Spring force swung forward into the locking position and the bond is closed.

The slope 49 serves as when entering the binding Guide surface which, as soon as it abuts the pin 9, after pressing the heel further down shifts in front. It is essentially the same Function like the projection 11 with the guide surfaces 33 in the previously described embodiments.

The locking levers are good in the recesses 48 protected so that there is no danger that when running these levers can get stuck somewhere.

From Fig. 10 B it can be seen even better how the two Pins 9 and 9 'attached to the side cheeks 7' and 7 '' are and protrude towards each other. That too is Recess 48 and its protective function for the locking lever 52 and 52 'clearly visible.

In connection with FIG. 10A, it should also be pointed out that the rope 12 also up inside the boot can be led to the shaft and for example runs between the inner shoe and the shell. Basically this arrangement is possible in all exemplary embodiments.

So that the locking position of the locking lever is securely fixed and does not depend on the force of the spring, it is appropriate to the center axis of the rotary shaft 53 closed binding above the central axis of the cones Arrange 9 or even a little forward towards Boot tip offset. Vertical up from the Snowboard surface forces would then be in the first case no torque on the locking lever Exercise 52 or with the axle still further forward the rotary shaft 53 even a locking lever 52 still Torque more strongly in the locking position produce.

11 are inside of the second binding part 6 lying pin 9 over Articulated lever 60, 60 'connected to the pivot lever 40, whereby both ends of the articulated levers 60, 60 'each by means of a swivel joint to the pin 9, 9 'and Swivel levers 40 are connected. A central axis of the Swivel lever 40 here extends perpendicular to the central axis the pin 9, 9 '. A center axis of the swing levers 60 In contrast, 60 'lies at an angle of approximately 45 ° to the Central axis of the pivot lever 40. The two pivot levers 60 and 60 'are parallel to each other and are each on End of the pivot lever 40 connected. Will the Swivel lever 40 rotated about its swivel axis 41 (in Fig. 11 clockwise), the articulated levers 60 and 60 ' one pulling force each on the pins 9 and 9 'and pull this into the interior of the second binding part 6. On one The traction element 12 is connected at the end of the pivot lever 40. For this purpose, a blind hole 63 and an adjoining through hole 64 is provided. The tension member 12 is through the through hole 64 threaded and through a knot, a ferrule or similar thickened at its end so that it no longer can be pulled through the through hole 64.

The thickened end is then in the blind hole 63 arranged sunk.

In contrast to the previously described exemplary embodiments the traction element 12 runs inside the second Binding part 6 approximately at right angles to the central longitudinal axis of the shoe and is therefore led out to the side of the boot.

The second binding part 6 is - as in principle with the other embodiments - as a plastic injection molded part trained that retrofitted to the sole of a boot can be screwed on. There are four of them Screw holes 65 are provided. To the binding parts in this To be able to accommodate binding element 6 is a recess 66 provided that the individual parts including the Spring 28 picks up. This spring 28 is U-shaped here curved leaf spring formed on the inside of the binding part projecting ends of the pins 9 and 9 ' What is supported from the detailed view of Fig. 11a becomes clearer.

In Fig. 11 it can also be seen that the second Binding part 6 has holes 70 on both sides, through which the traction element 12 can be brought out, since it it is generally desirable to have the pulling element on the Outside of the respective boot, so on the right boot on the right side and on the left Boots on the left side.

11a shows an enlarged detailed view of a Detail of Fig. 11, namely the implementation of the pin 9 through the wall of the second binding part 6 Snowboarding offers great flexibility in all directions regarding the movements of the foot, which is desirable Most snowboard boots ridden with flat bindings but have a relatively hard outer shell, this is Flexibility cannot be achieved through shoes alone. For this reason, the pin 9 is fixed with the the second binding part 6 connected to the boot is flexible stored. For this purpose, the pin 9 is in a metal sleeve 69 slidably mounted, which in turn by a elastic sleeve 68 with the second binding part 6 in Connection is established. This elastic sleeve 68 can for example rubber or another resilient Material, e.g. also elastic plastic. At Production of the second binding part 6, the "housing" is produced from plastic using injection molding technology it is possible to use this flexible sleeve 68 in a second Injection molding in the same injection mold, with what the sleeve 68 also has a very good connection with the Binding part 6 is received. Through this spring-elastic storage the peg, which is the essential force between the Picking up your snowboard and boot are not just bumps cushioned and absorbed but the boot can also be around tilted at an angle of 1 ° to 3 ° transversely to the longitudinal direction be, which significantly increases the comfort when driving.

It can also be seen from FIG. 11 a how the spring 28 is supported on the pin 9. This one has here illustrated embodiment a radially protruding Bund 67, which on the one hand serves as a stop, the one Limit position of the pin defined and on the other hand the spring 28 is supported. The spring has one Bore 28 'through which the inner end of the pin protrudes through which the articulated lever 60 (Fig. 11) is connected via the pivot bearing 61. At this It should be emphasized that the flexible mounting of the pins 11a application in all variants of the invention Can be found.

Alternatively or in combination with this flexible storage of the pin, the first binding part 7 can also be flexible attached to the snowboard by, for example, (like explained in more detail in connection with FIG. 13 between the snowboard surface and the first Binding part a spring elastic plate made of rubber or flexible plastic is interposed.

Fig. 12 shows a further development of the invention, at which the traction member 12 to open the binding even further is extended and sometimes also in the driver's clothing is integrated. The tension member can thus be of any height be carried out as is most convenient for the driver. It has proven expedient if the traction element is approximately up to to the level of the thigh, where it is by hand of the driver can be gripped without bending over. For this purpose, the one attached to the free end of the traction element 12 Loop 13 over a carabiner hook 71 or another, easy-to-operate suspension device with a Extension belt 72 connected, this belt 72nd is preferably performed inside the snowboard pants and only comes out at an opening 76. There the extension strap 72 a further loop 77, the can be taken by hand. This loop is 77 by a rubber band 78, for example on the belt of the Pants or attached to a loop sewn on the pants is held in place.

Most snowboard pants today have a top of boot 1 partially overlapping cuff 74, the is sewn at the level of the shin along a seam 75. The extension belt 72 is between in this area the pants 73 and the cuff 74 out. If the driver attracts the boot 1, so he only has to once Extension belt 72 over the carabiner hook 71 with the Connect loop 14 of the tension member 12 and then has for all day the high comfort in the operation of the Binding.

13 shows a further variant of the invention, the basically applicable to all embodiments is. The shoe-side second binding part is not here more in the heel but in the middle of the sole of the Boots 1 housed. The snowboard side is accordingly Binding part 7 in a middle position on the snowboard attached. So that the boot 1 is only through both pins fixed and no longer by a front bracket. To pivot the boot around the axis of rotation of the pins to prevent are on the snowboard surface in the heel and Tip area of the boot tread plates 80 and 81 applied, for example by sticking with them the location of the boot is defined. These step plates 80 and 81 are preferably made of rubber-elastic material, to provide cushioning and shock absorption and a some flexibility for relative movement of the boot towards the snowboard. The tension member 12 is in the same way as in the other embodiments operatively connected to the pin, so that the binding otherwise in the manner described above is working. Because with this variant the boots are not against a front bar must be pushed forward are the Sidewalls of the snowboard-side binding part 7 somewhat designed differently. Has the top of the side bolsters two V-shaped guide surfaces 10 and 10 ' end in a circular trough 17. Through this The guide surfaces 10 and 10 'become the boot when put on the spigot on these guide surfaces towards the trough 17 passed, where then according to the embodiment 3 and 3a, the trough 22 ensures that the pin pressed inwards and only when the opening is reached 8 go into their locking position.

To make the entire binding a little more elastic, is here between the surface of the snowboard S and that Snowboard side first binding part 7 is still a rubber elastic Block 82 inserted.
