Support element for supporting the front sole upwards, for example in the form of lugs that overlap the front sole.

Since the aforementioned elements are generally known Components and system elements of a touring, cross-country or telemark binding no further description is required. It should be noted that the bindings according to Figures 1 to 10, the support member 14 in shape a so-called toe iron with the shoe supporting laterally Side jaws 16 is formed. Also acts in this regard it is a conventional component, on the detailed description can be dispensed with here.

Otherwise, the first bond according to the Figures 1 and 2 characterized in that the holding device with the the shoe 11 is held in the support device 14 in such a way that the heel 13 can be raised freely according to FIG. 2, is formed by a comparatively rigid clamping plate 39, those in the area of the metatarsal zone 17 are horizontal or parallel to the tread of the front sole 12 and transverse to Axis 18 extending shoe longitudinal direction is pivotable, so as can be seen in FIGS. 1 and 2. Furthermore is the clamping plate 39 can be moved back and forth in the longitudinal direction corresponding to the double arrow 40. For this purpose, the two side jaws 16 of the toe iron 14 elongated holes 41 educated. Inside these slots are on the inside lateral cheeks 42 of the clamping plate 39 arranged and the pivot pin defining the pivot axis 18 is longitudinally displaceable stored.

The double arrow 43 in FIG. 1 also indicates that Possibility of height adjustment of the pivot axis 18, e.g. through two or more elongated holes 41 arranged one above the other.

The clamping plate 39 is with a not shown Coupling mechanism coupled, e.g. with one in front of the toe iron 14 arranged clamping lever, preferably via a rigid Power transmission element, e.g. one below the toe iron longitudinally displaceable linkage, which with the Clamping plate 39 on the one hand and the mentioned clamping lever on the other hand is connected.

In Figures 1 and 2, the clamping plate 39 is in its Shown closed position. The rear end of the clamping plate 39 is bent forward in a U-shape. It engages in one correspondingly or complementarily shaped recess or Undercut 26 at the rear end of the front sole 12, i.e. immediately in front of the shoe arch 44, as shown in FIGS Figures 1 and 2 is shown. The clamping plate 39 extends if the shoe is depressed below the tread of the Front sole 12. So that the clamping plate 39 does not align with the rear End of the toe iron 14 collides, the front half of the Clamping plate 39 excluded accordingly. So that at Lifting the heel 13 of the clamping plate 39 accordingly Figure 2 swivel upwards without collision.

The pivot axis 18 of the clamping plate 39 is located at the shown binding about halfway up the Front sole 12. As briefly explained above, it can also do something be placed higher or lower, preferably by arrangement corresponding elongated holes 41.

The binding according to Figures 3 and 4 differs of that of Figures 1 and 2 essentially only in that the relatively rigid clamping plate 39 by a Tension cable 25 is replaced, which on the outside of the arranged two side jaws 16 of the toe iron 14 Deflection elements 65 held longitudinally displaceable (double arrow 45) and can be deflected upwards when the shoe heel 13 is lifted, as shown in Figure 4. Specifically are the Outside of the two side jaws 16 of the toe iron 14 two Deflection elements 65 arranged, in different Height and different longitudinal position, so that the longitudinal and / or The height of the cable deflection can be individually adjusted is. The tension cable 25 is with one for cable ties usual operating mechanism in front of the toe iron 14 connected. On one side, the tension cable 25 can still Tension spring element include to in under elastic bias To be kept in the closed position. On the sole side, this applies Tension cable into one at the rear end of the front sole 12 trained undercut 26 a.

FIGS. 5 to 7 show a new step-in binding shown in combination with a holding device similar that of Figures 1 and 2. The holding device is however in contrast to the binding according to FIG. 1 and 2 formed by a flexible elastic tension band 24, which is mounted for longitudinal displacement in a binding housing 46, with a support device at the top of the binding housing 14 is mounted in the form of a toe iron. The Strap 24 is specific between the base plate of the toe iron 14 and the top of the binding housing 46 is longitudinally displaceable stored. The rear end of the strap 24 is similar to the rear end of the clamping plate 39 according to the Figures 1 and 2 bent forward U-shaped. The interaction between front sole 12 and strap 24 takes place in the described with reference to Figures 1 and 2. Like Figure 5 can be seen, is in the release position of the binding Tension strap 24 through an elastically pre-tensioned toggle mechanism 47 in a swung up or here Concrete upward bent position, being at the entrance in the binding and depressing of the shoe 11 in the direction of Arrow 48 of the toggle mechanism 47 in a lower Excess dead center position according to Figure 6, in which the Tension strap 24 is moved and held in the closed position. The displacement of the strap 24 in the closed position is in Figure 6 indicated by the arrow 49.

The toggle mechanism 47 includes a rear, itself extending parallel to the longitudinal direction of the ski and on the binding housing 46 hinged lever 50 and a front, yourself also extending parallel to the longitudinal direction of the ski, on longitudinally mounted tension band 24 on the one hand and on articulated front end of the rear lever 50 on the other hand Lever 51, the strap 24 on the top of the supports front lever 51 of the toggle mechanism. Concrete the rear end of the strap 24 is supported on one protruding projection at the rear end of the front lever 51 from.

That associated with the front end of the front lever 51 Swivel axis 53 is within an elongated hole passage 52 in Binding housing 46 mounted longitudinally. This Pivot axis 53 is also with a flat element 54 connected to the front end of the strap 24, here specifically a rivet connection 55 is provided.

The toggle mechanism 47 is also an opening means 56 assigned, which with a here in front of the shoe 11 or Toe iron 14 arranged actuating lever 57 is coupled, such that when acting on the operating lever in the direction arrow 58 in FIG. 6 shows the toggle mechanism 47 its lower dead center position to the upper Excess dead center position according to Figure 5 is movable. The Opening means 56 comprises a longitudinally displaceable Wedge 59, one, namely front wedge surface 60 against the connecting the front and rear levers Hinge axis 61 is adjustable while raising the same over the Dead center line created by the connection between the front and rear linkage of front and rear lever is defined.

In the embodiment according to FIGS. 5 to 7, this is Clamping means a spring-elastic strap 24. At the Embodiment according to Figures 8 to 10 is the clamping means by means of a longitudinally displaceable clamping plate 39 formed corresponding to that according to Figures 1 and 2, the clamping plate 39 specifically on a longitudinally displaceable mounted bearing bracket 62 is pivotally mounted. This Bearing bracket is with the front pivot axis 53 of the front Lever 51 connected, again by a flat element 54th

The opening wedge 59 is connected to the operating lever 57 by a rigid linkage 63 connected, which within the binding housing 46 is mounted for longitudinal displacement.

The operating lever could also be behind the heel be arranged. In this case the opening mechanism would be equally trained, only effective in the backward direction.

At the top of the operating lever 57 is another Recess 64 formed for a ski pole tip, so that with the ski pole by pressing in the direction of arrow 58 the binding can be opened easily without the skier bending down got to.

In all of the described embodiments, the front sole 12 only at the front sole end through this overlapping Knaggen 15 held. The lugs 15 are on the inside Side jaws 16 of the toe iron 14 are formed.

The binding according to FIG. 11 is characterized by that the lugs 15 of a toe iron so far back are offset that the front sole 12 on the ski 10 to metatarsal zone is held so that when lifting the Heel 13 a bend of the front sole 12 only from the metatarsal zone 17 is possible. In a similar way the bonds according to FIGS. 12 and 13 are also formed.

The different bindings described differ in essential only by different holding devices, all holding devices have in common that they are in Area of the metatarsal zone 17 are connected, namely in order to be approximately parallel to the longitudinal direction of the shoe Sole tread or horizontally extending axis 18 biegoder held pivotable, in particular pivotable are stored. Furthermore, all holding devices common that they are at the rear end of the front sole, especially in the transition area to the shoe arch on this can be connected.

In the binding according to FIG. 11, the holding device comprises one in the metatarsal area 17 around a horizontal one Transverse axis 18 sole plate 34 pivotally mounted with a longitudinally movable (double arrow 36) movable sole clamping means 35, which in the region of the articulation of the soleplate 34, i.e. in the area of the horizontal transverse axis 18 deflectable and with one in the front area of the support device 14 about a horizontal transverse axis 30 in the direction of Double arrow 31 pivotally mounted clamping lever 29 connected is.

In the binding shown, the tensioning means is 35 a flat band made of stainless steel, which within the Sole plate 34 is longitudinally displaceable in the direction of the double arrow 36 is stored. The rear free end of the Tension band 35 is bent like a hook upwards and forwards in a complementary transverse groove on the underside of the front sole 12 can intervene, as shown in Figure 11 is.

If the strap 35 is relatively rigid, it ends within the sole plate 34 before the articulation thereof the axis 18. In this case, the front end of the strap 35 preferably with a flexible cable, in particular Steel wire connected in the region of the hinge axis 18 deflected and forward to the inside of the binding housing Clamping lever 29 is guided. The strap 35 can by a spring not shown here in the shoe release position be biased so that the movement of the strap 35 in the Shoe holding position according to Figure 14 against this elastic pre-tension takes place, and by appropriate Depressing the tensioning lever 29 downwards into a front Position according to Figure 11. In this position the clamping lever 29 is then preferably in an over-center position. If the tensioning lever 29 is outside this dead center position brought, causes the aforementioned elastic bias on the Strap 35 a movement of the same in the shoe release position.

The elastic preload mentioned also affects Lifting the heel 13 off, albeit in a relatively small amount Dimensions. This creates a corresponding provision between the shoe and causes skiing or similar sports equipment.

The binding according to FIG. 12 differs from that of Figure 11 in that the holding device flexible elastic strap 24 made of stainless steel or the like permanently flexible material and at the same time as sole tensioning means serves. 13 in the embodiment the holding device a tension cable 25. This tension cable 25 engages in one on the underside of the front sole 12, namely formed in the rear area of the same transverse groove. Concrete this groove is an undercut 26th

Regarding concrete forms of construction of these holding devices the applicant refers to them decreasing WO 96/23558.

The strap 24 has the advantage that this is the curvature the front sole 12 in the area between the metatarsal zone 17 and Arches also defined. The front sole 12 is supported in this area on the strap 24 literally. The Tension cable construction 25 can operate in a similar manner be when the tension cable is completely at the bottom of the Front sole 12 bears, that is, not laterally on the front sole 12 is guided past, as is the case in FIG. 13.

Otherwise, in the case of the binding according to FIG Tension strap 24 with its front end not articulated to the Support device stored, but firmly clamped. The Corresponding clamping block is marked with the reference number 27. This clamping block is inside the binding housing, here within the front sole section assigned support plate 21 in the direction of the double arrow 22 stored back and forth, and for this purpose via a rigid connecting element 28 connected to the locking lever 29, its function in more detail with reference to FIG 11 is described. In this way, the clamping lever 29 the clamping block 27 and thus the associated clamping plate 24 Can be moved back and forth in the longitudinal direction of the shoe, i.e. the latter out a shoe release position into a shoe hold position corresponding to Figure 12 and vice versa. The back and forth Movement of the clamping plate 24 is also in Figure 12 with the Double arrow 36 displayed. The clamping plate 24 has a width on, which is less than the width of the support plate 21 and thus also less than the width of the front sole 12.

Of course, it is also possible to use the front end of the To link the tensioning strap 24 to the tensioning block 27, i.e. in the clamping block 27 to be pivotable about a horizontal transverse axis corresponding to the transverse axis 18 in Figure 11. In the embodiment according to FIG. 12, the entire holding device, i.e. Tension strap 24, associated tension block 27 and Connecting element 28 reciprocates in the longitudinal direction of the shoe, to release the shoe 11 or on the support device 14 hold.

It is very similar with the binding according to the figure 13. The linkage of the Tension cable 25 on both sides of the front sole 12 each upright cheeks 32 of a U-shaped connector 33, which also has a rigid connecting element 28 connected to the locking lever 29 and by pivoting the same back and forth about the axis 30 in the shoe longitudinal direction is movable, so that the tension cable from a shoe holding position corresponding to Figure 13 in a shoe release position and vice versa.

It is with the bindings according to FIGS. 12 and 13 also conceivable, the clamping means 24, 25 or the associated Connection elements 27, 32 in the direction of the shoe release position preload elastic. In this case, the fasteners 28 not be rigid; then it can flexible tensioning cables or wires can also be used. Of course there are also bindings 12 and 13 of the locking lever 29 in the shoe holding position in an over-dead center position.

Both the tensioning cable 25 and the tensioning plate 24 effect when lifting the heel 13 a provision between Shoe and ski, which with increasing lifting of the heel 13 increases accordingly.

In the bindings according to Figures 11 to 13 the bending line or pivot axis 18 of the holding device below the front sole 12.

In the binding according to FIG. 11, it can still be advantageous be, the sole plate 34 slightly lower than the sole support surface 38 in the area of the front sole section to assign associated support device 14. This is one Bulging of the front sole 12 in the transition area between the Sole support surface 38 and the sole plate 34 down possible if the heel 13 is raised up. at This is the binding according to FIGS. 12 and 13 less problematic since neither the tension cable 25 nor the Strap 24 a bulge of the front sole down when Obstruct lifting of the heel 13. This is especially true for the binding according to Figure 13, in which the tension cable is guided past the front sole 12.

If the pivot axis 18 are at the level of the front sole 12 is, the pivot axis 18 is arranged laterally Trunnions defined, their axes at the level of each other aligned. The pivot pins are then in the side Cheeks of the binding housing arranged between which the Shoe, in particular the front sole 12 of the same is placed.

It goes without saying that the aforementioned bond is different not only suitable for skis or similar snow gliders, but also for roller, cross-country or touring skis.

Furthermore, it should be pointed out that the support device a locking device for one on the bottom the sole in the metatarsal area of the same Undercut, transverse axis or the like sole holding element may include. The cross axis mentioned is preferably within one at the bottom of the sole trained recess arranged and with the sole integrated. The locking device comprises a locking hook, which engages behind the transverse axis and thus the front one Sole section firmly attached to the ski or between the ski and boot arranged binding plate holds. The mentioned hook is connected to a locking lever on the support device 14 is pivotally mounted, preferably around one Horizontal axis extending transversely to the longitudinal direction of the ski. at this binding can be used on cross-sole support elements 15, as indicated in FIGS. 11 to 13, to be dispensed with. For this reason, the support elements 15 to support the front sole section up into the Figures 11 to 13 also only indicated schematically. The Representation should also be a support device of the aforementioned Kind of include.

Regarding the exemplary embodiments according to FIGS. 5 to 10 mentioned that the toggle mechanism 47 by a Helical compression spring is elastically biased. This supports themselves in the illustrated embodiments with their rear End at the articulation between the front and rear Lever on the one hand and with its front end on the binding housing 46 on the other hand. In the lower over-center position according to FIGS. 6 and 9 is the helical compression spring 65 mentioned axially compressed compared to the top dead center position according to Figures 5 and 8. The elastic bias the helical compression spring 65 ensures bistable Location of the lever 50, 51 or the toggle mechanism 47 in the lower and upper dead center position. The dead center line is defined by the connecting line between the rear linkage of the rear lever 50 and the front Linkage of the front lever 51. It is also conceivable instead the helical compression spring 65 described a helical tension spring between the rear linkage of the rear lever 50 on the one hand and the front linkage of the front lever 51 on the other hand. This also makes the required Bi-stability of the toggle mechanism 47 reached.
