Description

RELEASABLE SKI BINDING

The invention relates to a releasable ski binding with a stand or support plate provided as a standing surface of a ski boot, which is arranged on or on a ski-fixed or ski-mountable base part about a (vertical) vertical axis of the base part against adjustable resistance, and with on the Stand or support plate arranged, releasable front and rear shoe or sole holders, which cooperate positively with the shoe or shoe sole-side counter surfaces or elements in a position of use and fix these essentially stable or stable, the rear sole holder adjustable to a release position against adjustable resistance and the front shoe or sole holders are locked within a predetermined angle of rotation range of the base or support plate and are unlocked outside the rotation range. In practically all ski bindings currently available on the market, a front shoe holder assembly and a rear shoe holder assembly are arranged on the ski, the front shoe holder assembly interacting with the toe end and the rear shoe holder assembly with the heel end of the (standardized) shoe sole of a ski shoe, namely such that the toe end of the sole from the front shoe holder assembly is prevented from moving forward in the longitudinal direction of the ski and from movements in the direction of the vertical and transverse axes of the ski, while the end of the sole from the rear shoe holder assembly is prevented from moving backward in the longitudinal direction of the ski and against movements in the direction of the vertical and transverse axes of the Skis is secured. Such bonds have reached a high standard of development and high security. In principle, however, they have the disadvantage that soiling, which may get stuck between the soles and shoe holder assemblies, can have an influence on the release behavior. For this reason, ski bindings have already been developed in accordance with US Pat. No. 4,182,524, in which the ski boot stands on a binding-side base or support plate which can be rotated about a ski vertical axis against adjustable resistance. When the shoe is inserted into the binding, the shoe sole is fixed on the support by means of plate-side shoe holder elements which interact with counter elements on the sole side. If the shoe or the foot of the skier tries to execute a rotational movement with respect to the vertical axis of the ski in the event of a fall, the rotational resistance to be overcome during this rotation is removed in the case of a binding according to US Pat. No. 4,182,524. finally determined by elements on the binding side, which can in principle be arranged in a dirt-protected manner, according to US Pat. No. 4,182,524, for example, within the stand or support frame.

[006] Nevertheless, the binding according to US Pat. No. 4,182,524 does not yet have a satisfactorily reproducible behavior. The rotational resistance opposing a rotation of the standing or supporting points about the vertical axis is determined by a spring arrangement which also brings about the release resistance of the shoe holder elements on the rear side. The arrangement is designed such that the shoe holder elements receive an increasing amount of movement in the direction of their position releasing the shoe when the stand or support points are rotated about the vertical axis. Conversely, the stand or support points receive a rotational play as soon as the shoe holder elements are moved in the direction of their position releasing the shoe by relative movements between the stand or support points and the shoe sole. Soiling occurring between standing or wearing points and the sole of the shoe can on the one hand influence the release behavior of the binding and on the other hand the rucksack behavior of the binding within its so-called elastic range, within which disturbing forces acting on the binding may not yet cause movements of binding elements or parts lead to a release of the binding, so that the binding can return to the normal state that fixes the shoe in the predetermined desired position when the interference force disappears.

DE 40 10923 AI shows a ski binding that largely reveals the features of the preamble of claim 1. However, it remains unclear whether the toe sole holder is locked or can be released in the normal position of the standing positions.

A similar ski binding is the subject of DE 34 15 272 C2, but with the difference that the toe end of the ski boot is held without releasability.

The object of the invention is now to ensure a particularly reproducible release and elasticity behavior in a ski binding.

This object is achieved in that the front shoe or. Sole holders are pivotable about essentially horizontal longitudinal axes.

The invention is based on the general idea of excluding any critical recurring movement between the sole of the shoe and the stand or support points within the elastic range of the binding if rotational movements of the stand or support points caused by disturbing forces occur about the vertical axis. Because of the small angles of rotation of the standard or supporting points there is permanent locking of the front shoe or sole holder, there can be no play, in particular turning play, the shoe sole recive to the stand or support points. Within the range of elasticity, the rotational movement of the supporting or standing points remains recurrent to the standing or supporting points without affecting the position of the shoe or sole holder.

The front shoe or sole holder, which can be pivoted about horizontal longitudinal axes, ensures great freedom in the design of the shoe sole. The sole can thus be shaped in such a way that the skier can walk well after releasing the shoes from the binding.

It should be emphasized that, according to a preferred embodiment of the invention, the rear sole holders can only be released in the vertical direction, i.e. by forces that try to lift the heel area of the shoe vertically from the stand or support points. Accordingly, shear forces in the heel area can occur no shifts between the sole or stand or support points.

As far as possible disturbing forces try to lift the shoe vertically from the stand or support points by adjusting the rear shoe holder in the direction of the release state, any contamination between the stand or support points and the sole of the shoe cannot exert any disruptive influence.

According to a ^ nz particularly preferred embodiment of the invention, the stand or supporting points is assigned a torque support which is based on the stand or. Transforms supporting points with respect to a transverse axis of the point into torques with respect to the vertical axis and generates a torque that supports a further rotation of the standing or supporting points about the vertical axis as soon as the standing or supporting points has left a middle position or a middle position area. In this way, the fact can be taken into account that torsional loads on the shinbone as well as on the foot and knee joints are to be reduced if the leg is additionally stressed by additional forces which typically occur during a forward or backward fall. The disturbing forces responsible for further stresses are due to the aforementioned torque support as a result of reducing the rotation of the stand or. Support points around the vertical axis counteracting rotational resistance, with the result that a rotational stroke of the standing or support points unlocking the front shoe or sole holder and thus releasing the shoe are comparatively easy to achieve.

For the rest, reference is made to the preferred features of the invention Claims and the following explanation of the drawing refer to which a particularly preferred embodiment and some possibilities of modification are described in more detail. Protection is not only claimed for combinations of features expressly stated in the claims or the description. Rather, the protection of the present invention should also relate in principle to any desired sub-combinations of the combinations of features shown. In the drawing shows

7 shows a schematic sectional illustration of a torque support for the stand or points, FIG. 8 shows an exploded perspective view of the underside of a ski shoe sole interacting with the binding according to the invention, and FIG. 9 shows a perspective illustration of the underside of the sole as well as the front and rear sole holders, which interact with the shoe components on the sole. The binding according to the invention has a base points 2 arranged on a ski 1 indicated in detail in FIG. 1, which is pivotally connected with a front end piece 2 'in the longitudinal direction of the ski to a bearing part 3 arranged in a ski-like manner pivotably about a ski transverse axis and with a rear end piece in the longitudinal direction of the ski 2 "is vertically held in another ski-fixed bearing part 4 with displaceability in the longitudinal direction of the ski. On the base points 2 there is arranged a stand or support points 5 which can be rotated about a vertical axis of the base points 2 and whose top cover or top side, which is removed in FIG The standing or supporting points 5 has a lower part 5 'designed as a frame and structural part, see FIG. 2. The aforementioned connection of basic points which can be pivoted about a vertical axis 2 and standing or supporting points 5 is between the base points 2 and the lower point part 5 'arranged, wherein the pivot bearing can be formed, for example, that on the bottom part 5' an underside circular disk-shaped elevation is formed, which engages in a correspondingly circular recess in the base points 2 and is fixedly connected to a flange point 6 arranged on the underside of the base points, which overlaps the aforementioned circular recess of the base points 2 radially outward.

The standing or supporting points 5 are held by a latching device 7, which is explained in more detail below, in the central corner shown in FIG. 3, but can be reversed against the resistance of the aforementioned latching device 7 according to FIG. 5 to the longitudinal axis of the ski or the base points 2 are rotated.

On the stand or support points 5, front and rear sole holders 8 and 9 are arranged, which in their position of use (see FIGS. 1 and 2) the sole 10 of a shoe used in the binding practically immovable on the stand or Fix support points 5.

In the embodiment of FIGS. 1 to 6, the front sole holders 8 are pivotable about axes 11 extending in the longitudinal direction of the standing or supporting points 5 into a release position to the side of the standing or supporting points 5, while the rear sole holders 9 can be pivoted about one axis 12 extending in the transverse cross direction can be tilted into a release e.

As will be described in more detail below with an explanation of the latching device 7, the front sole holders 8 are locked in their position of use when the stand or. Support points 5 assume their normal position according to FIG. 3 or a position within a swivel range provided for the elasticity range of the binding on both sides of the normal position. As soon as this swiveling range to the right or left is exceeded, the front sole holders 8 are unlocked so that they can easily be folded into their release position or moved.

The rear sole holder 9 also cooperate with the second latching device 7 (or a separate latching device, not shown) explained below and with an actuating lever 14. With correspondingly large disturbing forces or moments acting on the rear sole holder 9, the rear sole holders 9 in FIGS. 1 and 2 are tilted clockwise into a release position which is designed to be self-retaining. In addition, the rear sole holder 9 can be switched between use and release position by the operating lever 14.

8 and 9, the sole 10 of the ski boot to be inserted into the binding has open openings approximately in the ball area or at a greater distance from the toe end of the sole to the underside of the sole and to the longitudinal edges of the sole. recesses 15 and a downward and to the aforementioned recesses 15 open recess 16 with a flat bottom, which is provided with receiving holes 17 for screws or the like. A fitting point 18 is arranged in the recess 16 and fastened by screws or the like, not shown, which are screwed into the receiving bores 17. The fitting points 18 has a slightly wedge-shaped front edge 18 ', the corner areas of which are positively received by corresponding recesses in the front sole holders 8 when the front sole holders 8 assume their position of use and the sole 10 in the longitudinal direction of the sole with the front edge 18' of the fitting points 18 in the aforementioned Aisnehmungen the sole holder 8 is inserted, the sole 10 with one of the fitting 18 adjacent bottom area 10 'on the top of the stand or support 5 near the front sole holder 8 is flat.

The above-mentioned positive connection between the corner regions of the front edge 18 'of the fitting points 18 and the recesses of the front sole holder 8 is designed in such a way that the sole 10 is secured or locked against displacement in the forward, lateral and vertical directions.

At the rear area of the sole 10 open recesses 19 are arranged downward and to the side edges of the sole 10, which merge into a recess 20 which is distant from the rear end of the sole, open to the recesses and to the underside of the sole and which has a flat floor with receiving bores 21 for screws or the like. In this recess 20 a fitting 22 is arranged and fixed with screws or the like, not shown, which are screwed into the aforementioned receiving holes 21. The fitting points 22 has a T-shape in plan view, such that angular bays 22 'are formed on the fitting points 22.

In their position of use, the rear sole holders 9 overlap the upwardly facing side of the fitting points 22 from above in the area of the bays 22 'when the shoe is inserted into the binding, the edges of the bays 22' extending in the longitudinal direction of the sole on the flanks of the sides facing one another the rear sole holder 9 and the edges of the bays 22 which extend in the transverse direction of the sole bear against the front edges of the rear sole holders 9 which are substantially vertical in the position of use, and an underside region 10 '' of the sole 10 which extends in front of the fitting points 22 is close to the top of the stand or support points 5 the rear sole holders 9 lie flat. Accordingly, the rear sole area is through positive locking held between the fitting points 22 and the rear sole holders 9 against movement in the rear, side and vertical directions.

The sole 10 essentially only has to be stiff between the fitting points 18 and 22, such that the fitting points 18 and 22 always have a reproducible position with respect to the areas 10 ′ and 10 ″ on the underside of the sole 10 and accordingly can interact with the sole holders 8 and 9 with play-free positive locking. The sole areas in front of and behind the fitting points 18 and 22 can largely be shaped as desired. In particular, the underside of the sole can be arched in these areas in such a way that a rolling movement of the foot is facilitated when walking.

2, 3 and 5 has a strong helical compression spring 24, the right end of which in the drawing is supported on a spring abutment which can be adjusted by means of adjusting screw 25 in the longitudinal direction of the standing or supporting points 5, so that the spring tension can be changed with a screwing tool which can be attached to the head 25 'of the adjusting screw 25 accessible at the rear edge of the standing or supporting points 5.

The other end of the helical compression spring 24 is tensioned against a piston 26 which is tensioned by the spring force against a facing cross member of a rocker arm 27, the aforementioned cross member of the rocker arm 27 engaging in a Cu slot on the facing side of the piston 26. The cross member of the rocker arm 27 is against by the thrust of the piston 26 against or in the stand or. Tragpkte 5 arranged tilt axes 28 and 29 pushed. In the normal position of the rocker arm 27 (see FIG. 3), the cross member of the rocker arm rests on the peripheral surfaces of the rocker axles 28 and 29 with approximately semicircular recesses. If the rocker arm 27 is pivoted about one of the rocker axles 28 or 29 from its position in contact with the rocker axles 28 and 29 with its cross member, the piston 26 is pushed back against the force of the helical compression spring 24 as soon as a preload on the helical compression spring 24 is overcome on the rocker arm 27 Moment is exercised.

The rocker arm 27 grips with a fork-shaped end a pin 30 which is seated firmly in a hollow axis 30 'formed on the base points 2. Accordingly, the rocker arm 27 must be deflected from its normal axis shown in FIG. 3 by pivoting about the tilt axis 29 when the standing or supporting points 5 on the base points 3 are rotated into the position shown in FIG. 5, the rotary movement being about the f nschpkte 6 (see. FIGS. 1 and 2) centrally penetrating vertical axis he follows.

[042] If the supporting or standing points 5 are rotated recurrently to the basic points 2 into the position opposite to the position in FIG. 5, the rocker arm 27 must pivot about the tilt axis 28.

[043] As a result, the standing or supporting points 5 can only rotate about the aforementioned vertical axis on the base points 2 if the standing or supporting points 5 are acted on by a sufficient torque, the dimension of which is due to the prestressing of the helical compression spring 24 is determined. As soon as this dimension is exceeded, there is a more or less large pivoting stroke of the standing or supporting points 5.

As soon as the swivel stroke exceeds a predetermined dimension (elasticity range), the front sole holders 8, which are normally held in the position of FIG. 4, are unlocked and can fold into the release position of FIG. 6.

To control the sole holder 8 is a slide 31, which is within the stand or. Tragpkte 5 is guided displaceably in the longitudinal direction. This slider 31 has oblique or helically wound control surfaces 32 which cooperate with corresponding oblique or helical control surfaces 33 on the sole holders 8 designed in the manner of double-arm levers: If the slider 31 is moved forward, i.e. 2, 3 and 5 pushed to the left, a torque is exerted on the sole holder 8, which attempts to place the sole holder 8 in the normal position of FIGS. 2 to 4. If a torque acts on at least one of the sole holders 8, which attempts to place the respective sole holder 8 from the normal position of FIG. 4 into the laterally folded position of FIG. 6, the slide is moved backwards, i.e. 2, 3 and 5 pushed to the right.

In the normal position of the standing or supporting points 5 according to FIG. 3, the slide 31 assumes its front or left end position in the drawing, whereby it is prevented from leaving this end position by having a middle extension of one arranged on the slider 31 control curve rests on the circumference of the hollow shaft 30 'carrying the pin 30.

[047] If the standing or supporting point 5 is rotatably turned to the base point 2, the hollow axis 30 'reciprocally moves sideways to the slide 31 such that the hollow axis comes into the region of one of the bays 31' formed on the control cam, which are formed on both sides of the central projection of the slide 31. The slider 31 can thus be moved recurrently to the standing or supporting points 5 to the right, so that the sole holders pivot into the release arches of FIG. 6 can.

In practice, the aforementioned rotation of the standing or supporting points 5 always takes place when the shoe inserted into the binding tries to transmit a corresponding torque to the standing or supporting points 5 due to interference forces. Due to this torque, one of the front sole holders 8 is always moved outwards from the shoe sole, i.e. 6, pushed. First, however, the respective sole holder 8 is locked because, despite the beginning rotation of the standing or supporting points 5, the slide 31 rests with its central projection on the hollow axis 30 'and is prevented from leaving the end position of FIG. 3. The shape or width of the central projection of the slide 31 determines the angle of rotation range of the standing or supporting points 5, within which the sole holders 8 remain locked. If this range of rotation angle, which is also referred to as the elastic range, is exceeded, the slider 31 is displaced to the right by the interaction of the slider-side control surfaces 32 with the sole holder-side control surfaces 33, since at least one sole holder 8 is acted upon by a torque that urges it outward. This is due to the fact that the sole of the shoe presses against the sole holder 8.

As long as the aforementioned torque remains effective on the sole holder 8 and accordingly the slider 31 is pushed to the right in the drawing, the interaction of the oblique flanks of the central projection of the slider 31 on the bays 31 'with the circumference of the hollow axis 30' causes an additional force that supports the started rotary movement of the standing or supporting points 5.

As soon as the sole holder 8 is no longer pushed aside and the stand or support points 5 are no longer subjected to a torque, the rocker arm 27 can move the stand or support points 5 into the normal position due to the force applied by the spring 24 3 push back, the slider 31 being pushed back into the position of FIG. 3 by the interaction of the hollow axis 30 'with the oblique flanks of the central projection of the slider 31 and accordingly also resetting the sole holder 8 into the position of FIG. 3.

[051] Deviating from the graphically illustrated embodiment, instead of the control cam, a slit-like backdrop can also be arranged on the slide 31, in which the pin 30 engages in the manner of a sliding block. With a corresponding shape of the backdrop, the slide 31 is then inevitably shifted between its end positions if the standing or supporting points 5 recive to the basic points sufficiently far between the untwisted normal position (FIG. 3) and a deflected position (FIG. 5) is twisted.

In this embodiment, the control surfaces 32 and 33 on the slide 31 and the sole holder 8 can be designed such that a torque that urges a sole holder 8 from the normal position (FIG. 4) into the release position (FIG. 6) does not yet provide the torque Slide 31 generates pushing force pushing away from its one end position (FIG. 3), as long as the slide 31 assumes a position near the end position of FIG. 3.

Such an embodiment of the control surfaces 32 and 33 is also possible with an embodiment of the slide 31 with a control cam according to FIG. 3 if the slide 31 is pushed away from the end position of FIG. 3 by an (additional) spring.

In the example shown in the drawing, the latching device 7 also controls the rear sole holder 9.

For this purpose, the pretension of the helical compression spring 24 is removed via a support part 36 on a further slide 37, which cooperates with the rear sole holders 9 in such a way that it assumes the end position shown in FIG. 3 when the sole holder 9 has the position shown in FIGS. 1 and 2 have a normal position in which the sole of a ski boot is securely held. When triggered, the sole holder 9 in FIGS. 1 and 2 pivot clockwise, the further slide 37 with the part 36 being displaced to the left against the force of the helical compression spring 24 in FIGS. 2 and 3. With sufficient further pivoting of the sole holder 9 in a clockwise direction, a release position of the sole holder 9 designed as an over-center position is achieved.

From this release position, the sole holders 9 are made when entering the binding, i.e. when inserting the shoe sole 10 into the binding automatically folded back into the normal position of use, since otherwise the fitting part 22 of the shoe sole (see FIG. 8) could not reach its position normally locked to the sole holder 9.

[057] Otherwise, the sole holder 9 can be switched between normal and release position by means of the lever 14, the lever 14 possibly being able to be actuated by means of a ski pole.

[058] When skiing, the stand or support points 5 have more or less large torques with respect to a ski transverse axis. If the skier is skiing with the previous one, the front end of the stand or support points 5 is pushed against the top of the ski. If, on the other hand, the skier has a reserve, forces and moments act on the standing or supporting points 5, which seek to lift the front end of these points 5 from the ski 1. [059] Correspondingly reverse forces occur at the rear end of the standing or supporting points 5.

[060] According to an advantageous embodiment of the invention, a torque support 41 can now be provided, with which torques acting on the standing or supporting points 5 with respect to the transverse axis are converted into torques with respect to the vertical axis.

As can be seen from the sectional view in FIG. 7, a profile strip 42, which extends in the transverse transverse direction and is fixed on its base, is arranged on the standing or supporting points 5 in the region of the end pieces 2 'and 2 "of the basic points 2 The top and the underside each have two elevations 43 and 44 with lateral oblique flanks and a horizontal section extending between them. On the end pieces 2 'and 2 "of the base points 2, counter elevations 45 and 46 cooperating with the elevations 43 and 44 are arranged.

7 shows the position of the elevations 43 and 44 recurrent to the counter-elevations 45 and 46 for the (normal) case that the standing or supporting points 5 assume their normal, non-pivoted position reciting the basic points 2, ie the longitudinal axes of the two points 2 and 5 coincide in a top view of the ski 1. In this case, the horizontal sections of the elevations 43 and 44 rest on the corresponding sections of the counter elevations 45 and 46. Regardless of the extent of any vertical forces that the front end of the stand or. Pushing support points 5 against the top of the ski or trying to lift them off the top of the ski and then leading to corresponding pressing forces between the horizontal sections of the mutually opposite elevations 43 to 46, then no effective torque can be generated which the standing or tr ^ pcts 5 tries to turn its vertical axis. However, if the standing or supporting points 5 are pivoted somewhat about the vertical axis against the resistance of the first latching device 7, the oblique flanks of the mutually opposite elevations 43 to 46 can interact with one another, so that a torque arises around the aforementioned vertical axis as soon as the front end the standing or supporting points 5 with the profile strip 42 is pushed downwards or raised upwards.

As a result, if the skier falls forward or backward, an additional torque with respect to the vertical axis acts on the standing or supporting points as soon as the standing or supporting points 5 are already deflected to a certain extent from their central position has been. This additional torque affects the Restoring forces generated by the first latching device 7 so that the standing or supporting points 5 can be brought more easily into the rotational position in which a front shoe or sole holder 8 is unlocked and the shoe is released from the binding. 1, the bearing part 4 can optionally also be designed to be adjustable, such that it releases the rear end of the base points 2 in a release position and the base points 2 accordingly together with the stand or support points 5 about the hinge axis of the Bearing part 3 is pivotable. Thus, the binding according to the invention can optionally also be used as a touring binding, wherein the bearing part 4 can optionally also be adjustable in a state in which the base points 2 are supported recurrently to the ski in an inclined position pivoted upward.
