Abstract

A binding-coupled ski boot shaft release is described in which the pivotable boot shaft 12 can be locked to the lower boot part 14 via a locking lever 20. The locking lever 20 can be pivoted into a locking position against a spring force 34 by a sole holder 64. This is intended to prevent the predefined triggering characteristic of the sole holder from being falsified by a possible intervention of the shaft release in the binding.

Description

The invention relates to a binding-coupled ski boot shaft release according to the preamble of claim 1. The invention also relates to a ski safety binding according to the preamble of claims 8 and 16, which can preferably be used in conjunction with the binding-coupled ski boot shaft release.

The shaft of a ski boot is released on the one hand via binding-coupled ski boot shaft releases of the type mentioned at the outset, in order to be able to be pivoted forward about a transverse axis to make walking easier. On the other hand, this pivotability for skiing is prevented by locking the pivotable boot shaft over the intermediate part.

DE-OS 28 08 805 describes a binding-coupled ski boot shaft release of the type mentioned at the outset, in which the intermediate part engages on the pivotable boot shaft on the one hand and on the other hand engages under the sole holding part of the heel holder.

In the case of a device for locking a ski boot according to DE-Gbm 87 16 068, the locking between a rear entry flap and a front shell part of the ski shoe takes place via a locking piston assigned to a cable pull, which in turn is acted upon directly by the sole holding-down part of the heel holder in order to simultaneously fix the boot to the ski.

A disadvantage of the conventional ski boot shaft unlockings is that the intermediate part which brings about the locking of the pivotable boot shaft engages in the ski binding itself.

An object of the present invention is now to: To create binding-coupled ski boot shaft release of the type mentioned, in which, despite the automatic locking and unlocking of the swiveling boot shaft still given by closing or releasing the sole holder, a predetermined release characteristic of the sole holder, falsifying repercussions on the sole holder are practically excluded.

To achieve this object, the features specified in the characterizing part of claim 1 are provided.

The idea of the invention is therefore to be seen in the fact that a locking lever by means of the sole holder is only transferred to and held in the desired locking position in which it engages on the one hand on the boot shaft and on the other hand on the lower boot part to lock the pivotable shaft. After each release of the sole holder, the spring force provided ensures that the locking lever automatically returns to an unlocking position to release the pivotable boot shaft.

Since the sole holder for loading the locking lever preferably has a special projection, in particular separated from the sole holding-down part, not only is a reliable transfer of the locking lever into the locking position always guaranteed, but also a clear separation between the sole holding-down function and the boot shaft release is possible.

The locking lever is expediently articulated on the boot shaft and bent at the free end for engagement with the lower boot part in the locking position. The hook-like bent end of the locking lever preferably engages in one on the Back of the lower part of the boot provided. For this purpose, the sole holder engages the locking lever when it is snapped in order to press it into the recess, as a result of which the two shoe parts are connected to one another.

In order to allow a limited pivoting of the boot shaft against a spring force while generating a restoring torque even when the boot shaft is locked, the boot shaft can expediently be elastically coupled to the lower boot part via the locking lever.

Although the effects of the release of the ski boot shaft on a predetermined release characteristic of the binding are to be excluded, it can be particularly advantageous for sole holders that can be released from both the height and the sides if, for example, the release lever is applied to the sole holder in the event of a backward fall in the height release direction. Without causing a height release, this can, for example, facilitate the side release or friction compensation in connection with such a side release.

Thus, according to a preferred embodiment variant, a backdrop is arranged between the hook-like bent end of the locking lever and the recess of the ski boot receiving this end so that when the boot shaft is pivoted into the reserve and the locking lever of the boot shaft is supported in the recess, the sole hold-down, in particular Heel holder, actuated via the locking lever in the height release direction.

The binding-coupled ski boot shaft release can be used particularly advantageously in connection with such a safety ski binding, which comprises a bearing part on which a transverse axis between a closing and an opening tion position pivotally a sole holder, in particular heel holder, is arranged, which is fixedly connected to a spring cage extending away from the bearing part, in which one side supported on the spring cage and with the other side in the direction of the bearing part or away from it on the spring cage slidably mounted locking piston Acting spring is housed, the line of force of the spring in a sense generating a closing moment runs past it at a distance from the transverse axis and a height-releasing link is arranged between the locking piston and the bearing part, which retracts when the sole holder is pivoted about the transverse axis from the closed position in the opening direction of the locking piston while increasing the spring tension.

The main advantage of such a known safety ski binding (DE-PS 31 22 653) is that the size of the restoring force in the height elastic range is as close as possible to the size of the release force without excessively strong release springs having to be provided. For this purpose, the transverse axis is arranged at a radial distance above or on the side facing the ski boot with respect to the central longitudinal axis running in the displacement direction of the locking piston, while the support point between the locking piston and the counter-locking means, i.e. the location at which the locking element rests on the counter-locking element, in Clamping position is on the other side of the central longitudinal axis. Due to this design, when the sole holder is pivoted from its closed position, relatively large proportions of the link locking resistance to be overcome act directly in the direction of movement of the locking piston without exerting the same side forces that try to press the locking piston onto its guides in the spring cage. This advantageously ensures that the release forces of the binding essentially through the properties of the detent spring and the design of the detent piston how the counter-locking can be determined, while the friction of the locking piston in the spring cage plays a comparatively minor role. At the same time, this ensures a well reproducible behavior of the safety ski binding. A spring cage in the sense of the present invention is to be understood as any component on which the release spring and the locking piston can be supported or displaceably supported in the desired manner.

Another object of the present invention is to develop such a safety ski binding that can advantageously be combined with the ski boot shaft release so that the advantages of the safety ski binding known from DE-PS 31 22 653 are maintained in a structurally simple manner and by multiple use of components and at the same time With essentially the same means a perfect page release is guaranteed.

To achieve this object, the features specified in the characterizing part of claim 5 are provided.

In the case of such a safety ski binding that combines a height release with a side release, an action of the sole holder by the locking lever of the ski boot shaft release in the height release direction in the event of a backward fall or a backward swiveling of the shaft means that the side release is facilitated in spite of the lack of a height release, or any frictional forces that may occur are compensated.

The side release link can expediently consist of a flat transverse surface of the spring-loaded locking piston and a flat opposite transverse surface of the counterpart fixed to the ski. Will the sole holder together with the bearing part around the ski fixed, at least substantially vertical axis pivoted, the locking piston is pressed back against the spring force due to the flat design of the interacting surface pair and thus generates a side restoring force.

In order to define a defined axis of rotation of the ski boot, a rotary member which is rotatably mounted about a vertical axis which is fixed to the ski and is rotatably engageable with the ski boot is advantageously provided. This forces the ski boot to clearly twist around an axis below the shin, which is important for a clean release.

In addition, a ski-fixed front sole hold-down device is preferably provided with a projection which is at a distance from the ski, projects to the rear and engages in a laterally continuous slot in the lower boot part.

The continuous slot on the side ensures that when the ski boot is rotated about the defined axis, the front of the boot can come off the sole hold-down device. The front sole hold-down fulfills a pure shoe sole hold-down function, which is normally carried out by a conventional toe piece. An actual front jaw is not necessary. The heel cheek fulfills both the height and the side release.

In the case of a safety ski binding that can again advantageously be combined with the ski boot shaft release with a sole holder that can only be height-triggered, as in particular according to the preamble of claim 5, a rotary member rotatably mounted about a ski-fixed vertical axis is provided according to the invention, which is used for fixing a defined axis of rotation of the ski boot can be rotatably engaged with the ski boot and in which a slider engaging around a ski-fixed stop at the front outer end is guided in a longitudinally displaceable manner and is spring-loaded in the sense of hooking with the stop.

Here, the vertical axis is preferably defined by a ski-fixed vertical pin, which has a flattened portion on its front, against which the spring-loaded slide is held, so that the slide, which is moved forward with a rotation of the rotary member counter to the spring force, is triggered laterally to release the side, particularly from a U-shaped one , at least essentially free transverse stop.

Further advantageous embodiment variants of the invention are specified in the subclaims.

• Fig. 3 is a partially sectioned plan view of the sole holder shown in Fig. 1 with an associated bearing part, and

According to FIG. 1, a ski boot 10 is fastened on a ski 18 by means of a safety ski binding, which includes a lower boot part 14 fixed to the ski and a boot shaft 12 which can be pivoted about a transverse axis 16. The two boot parts are connected to one another at the front via a spring element 38.

The ski boot 10 has a binding-coupled ski boot shaft release on its back. This ski boot shaft release comprises a locking lever 20 which acts on the one hand on the boot shaft and on the other hand on the lower boot part to lock the pivotable boot shaft 12 with the lower boot part 14.

The locking lever 20 is pivoted into the locking position against the force of a spring 34 by a heel-side sole holder 64.

To act on the locking lever 20, the sole holder 64 has a special, nose-like projection 86. This projection 86 is arranged separately above a sole holding-down part 64 'of the sole holder 64.

The locking lever 20 is articulated at the upper end on the boot shaft 12, while at the other, free end it is bent like a hook toward the ski boot 10 for engagement with the lower boot part 14. In the locked position, the hook-like bent end of the locking lever 20 engages in a recess 32 provided on the rear of the lower boot part 14.

The boot shaft 12 can be coupled elastically to the lower boot part 14 via the locking lever 20. Thus, even when the boot shaft 12 is locked, a limited pivoting of this boot shaft is permitted against a spring force, a restoring moment being generated when the shaft is pivoted.

The lever pivot axis is formed by a transverse axis 22 fixedly connected to the locking lever 20.

As also shown in FIG. 2 in particular, this transverse axis 22 of the locking lever 20 is guided laterally in the region of its two ends in an elongated hole 36 in or on the boot shaft 12 which extends essentially parallel to the rear wall of the boot.

The upper section of the locking lever 20 is received in a recess 26 of the boot shaft 12. Here, the locking lever is biased by a spring 28 into an upper position in which the transverse axis 22 abuts the upper limit of the elongated hole 36. The spring 28 is supported on the one hand on the end of the locking lever carrying the transverse axis 22 and on the other hand on a transverse wall of the pivotable boot shaft 12 which delimits the recess 26 downwards. A projection 120 is provided on this transverse wall, onto which the spring 28 is pushed with the relevant end (cf. FIG. 2). A corresponding projection 122 for the same purpose is provided in the region of the transverse axis 22 on the locking lever 20 for the other end of the spring 28.

The spring 28, which is supported at the lower end against a transverse wall of the boot shaft 12 delimiting the recess 26 and at the upper end on the locking lever 20, enables the aforementioned limited pivoting of the boot shaft 12 to the front in spite of the locking. Such pivoting takes place counter to the force of the spring 28 and at the same time generates a restoring torque.

The spring 34 which biases the locking lever 20 into an unlocking position is received in a recess provided in the lower section of the boot shaft 12 which delimits the recess 26. This spring 34 is supported on the one hand on the bottom of this recess and on the other hand on the locking lever 20.

As can be seen, for example, in FIG. 1, the lower section of the locking lever 20 is slightly angled towards the ski boot 10 relative to the upper section and runs parallel to the likewise bevelled outer wall of the lower section of the boot shaft 12.

Characterized in that the locking lever 20 when closing the sole holder 64 with the lower portion by the special projection 86 only in the lock and locked there with the boot bottom 14, this binding-coupled ski boot shaft release practically does not intervene in the binding, ie there is no Falsification of the specified or set release characteristic of the sole holder 64. Rather, it is sufficient, for example, a normal heel shoe, which in particular has a correspondingly designed stop 86, which engages the locking lever from behind when the binding is snapped on and presses it into the recess 32 in the lower boot part 14 , whereby the two shoe parts are connected to each other. At the same time, the spring 34 causes the locking lever 20 to be automatically pushed out of the locking recess in the lower part of the boot when the binding is opened, so that one can immediately go back to normal and comfortable without manipulating the lever by hand.

Between the hook-like bent end of the locking lever 20, which forms a kind of locking pin 30, and the recess 32 of the ski boot 10 receiving this end, a link 40 is provided with an inclined sliding track formed by the lower wall of the recess 32, on which the locking pin is located 30 supports. The backdrop 40 is designed or arranged such that when the boot shaft 12 is pivoted into the reserve and the locking pin 30 of the boot shaft 12 is supported in the recess or on its slide path, the sole holder 64 via the locking lever 20 and the projection 86 in the region of the arrow 88 acted upon in the height release direction. Here, the upper, left outer edge of the locking lever 20 is supported on the upper transverse wall of the boot shaft 12 which delimits the recess 26. On the opposite side of the transverse axis, the locking lever 20 is supported by a rounded projection 24 on the inner wall of the boot shaft 12 delimiting the recess 26. This rounded projection 24 facilitates pivoting of the locking lever 22 while at the same time resting on the inner boundary wall mentioned.

In the first exemplary embodiment according to FIGS. 1 to 3, a safety ski binding which interacts with the binding-coupled ski boot shaft release is provided, which is designed both for a height release and for a side release.

1 to 3 show, the ski safety binding comprises a bearing part 72, on which a sole holder 64, in the present case a heel holder, is arranged so as to be pivotable about a transverse axis 74 between a closed and an open position. This sole holder 64 is fixedly connected to a spring cage 80 extending from the bearing part 72, in the present case it is formed in one piece with it.

A spring 82 is arranged in the spring cage 80, which is supported on the one hand on a prestressing insert 84 screwed, for example, into the spring cage and on the other hand on a locking piston 78 which is displaceably mounted in the spring cage 80. This locking piston 78 is displaceable in the longitudinal direction of the spring cage 80 against the force of the spring 82 away from the bearing part 72.

The force line of action of the spring 82 runs past the transverse axis 74 in a sense generating a closing torque. Between the locking piston 78 and the bearing part 72 there is a height trigger link 76 which, when the sole holder 64 is pivoted about the transverse axis 74 from the closed position in the opening direction, causes the locking piston 78 to retreat while increasing the tension of the spring 82.

The height release 76 consists of a slide track 76 'formed on the bearing part 72 and a locking projection 76˝ formed on the locking piston 78.

The sole holder 64 further includes a sole of the boot bottom part 14 acting from above sole holding part 64 'and below a tread 64 vorgesehenen provided for closing the binding.

If a height force that reaches the release value acts on the sole holder, this sole holder 64 pivots with the spring cage 80 counterclockwise, the locking piston 78 being pushed backwards due to the sliding of the locking projection 76 'on the slide track 76' with compression of the spring 82. As soon as the culmination point 94 of the backdrop has been exceeded, the sole holder 64 automatically snaps into the open position.

In order to also enable a side release at the same time, the bearing part 72 is rotatably mounted about a ski-fixed, vertical axis H. The sole holder 64 including the spring cage 80 can therefore also be pivoted laterally together with the bearing part 72.

A side trigger link 90 is arranged between the detent piston 78 and a ski-fixed counterpart formed by a bearing journal 66. When the sole holder 64 is pivoted laterally from the closed position into a lateral opening direction, this side release link 90 in turn causes the latching piston 80 to retreat while increasing the tension of the spring 82.

The side release gate 90 can in the simplest case consist of a flat transverse surface 90 'on the spring-loaded locking piston 78 and a flat counter-transverse surface 90˝ on the ski-fixed bearing journal 66. It can be seen in particular in FIG. 2 that the flat counter transverse surface 90˝ of the exemplary embodiment described is formed by two laterally outer sections, only one of which is shown in FIG. 3. In the central area, the wall in question steps back towards the transverse axis 74, the transition in the section running according to a rounded curve.

In FIG. 3 it can also be seen how the transverse axis 74 on the one hand passes through the bearing part 72 and on the other hand is mounted in the side walls 112, 114 (cf. FIG. 2) of the sole holder 64. Finally, in FIG. 3, as in FIG. 1, a recess 92 is indicated in the sole region of the lower boot part 14, into which the sole holding part 64 'of the sole holder 64 enters.

The ski-fixed bearing pin 66 passes through the bearing part 72 whose outer end facing away from the ski 18 is the side trigger link 90.

The end of the bearing pin 66 which has the side trigger link 90 is designed as a widened head. The bearing part 72 placed on the journal 66 is arranged between this widened head and a ski-fixed base 70.

The sole holder 64 can accordingly be pivoted laterally about the vertical axis H defined by the ski-fixed bearing journal 66. Due to the flat design of the pair of surfaces 90 ', 90˝ of the side trigger link 90, the spring-loaded locking piston 78 is pushed back with each pivoting, so that a side restoring force is always generated. From a predetermined pivoting angle of the sole holder 64, the ski boot 10 is released laterally. On the other hand, the lateral force always collapses as soon as a height release begins, since the latching piston is also pushed away from the bearing part or the bearing journal with each height release.

The ski safety binding according to the first exemplary embodiment further comprises a rotary member 48 which is rotatably mounted about a vertical axis 46 fixed to the ski. This vertical axis 46 standing on the ski 18 is defined by a vertical pin 44 which is preferably attached to the ski 18 in the region of the ankle. To define a defined axis of rotation of the ski boot, the rotary member 48 placed on the vertical pin 44 is at least partially received in a longitudinal slot 56 on the underside of the lower boot part 14.

The vertical pin 44 has on its side assigned to the heel holder 64 a flat, against which a through a spring 54 loaded locking piston 50 is held. Each time the ski boot 10 and thus the rotary member 48 are pivoted, a restoring torque is accordingly generated. The rotary member 48 also has a free space 52 for the air displaced by the locking piston 50.

In addition, a ski-fixed front sole hold-down device 62 is provided. This block-like sole hold-down 62 has a projection 60 projecting from the rear and at a distance from the ski 18. This projection 60 engages in a laterally continuous slot 68 in the lower boot 14. Accordingly, an extension 58 engages under the protrusion 60 in the sole region of the lower boot part 14.

A special feature of this first embodiment of the ski safety binding is therefore that no actual toe is provided, but rather a longitudinal slot is formed in the middle of the boot, in which a rotating member rotatably mounted on the ski is accommodated. This forces the ski boot to be clearly rotated about an axis, preferably located below the shin, which is important for a clean release. At the front, the sole sits with the extension 58 under the projection 60 of the sole hold-down device 62, the laterally continuous slot 68 ensuring that the shoe can be released laterally from the hold-down device at the front when it rotates about the vertical or vertical axis 46. This sole hold-down has a pure shoe sole hold-down function, which is normally carried out by a conventional toe piece. Both the height release and the side release only take place via the heel cheeks.

In the event of a backward fall, the lower locking pin 30 of the locking lever 20 is supported on the slide track formed by the lower boundary of the recess 32. In the area of arrow 88, the sole neck is thus acted upon ters 64 over the projection 86 in the height release direction. With this loading of the sole holder 64, the pivoting of the sole holder about the transverse axis 74 mounted in the side walls 112, 114 and passing through the bearing part 72 (see also FIG. 2) and the associated pushing back of the spring-loaded detent piston 78 facilitate side release or a compensation of the friction forces occurring on the front sole hold-down 62.

In order to further reduce these frictional forces, in particular for a side release, the shoulder 58 of the shoe sole, as shown in FIG. 1, engages with play in the space below the projection 60 of the front sole retainer 62. On the other hand, a friction lining can be provided between the sole and the surface of the projection 60, in particular on the sole. In the event of a backward fall, this friction lining automatically disengages from the projection 60 or the sole.

In the second exemplary embodiment according to FIG. 4, the same ski boot shaft release is provided with the same locking lever 20 as in the first exemplary embodiment. In contrast to this, the heel holder 64 cooperating with the ski boot shaft release is, in contrast to the first exemplary embodiment, only designed for a height release, while a special side release is provided in the front area of the shoe sole.

4, the bearing part 72 ', on which the sole holder 64 is pivotally arranged about the transverse axis 74, is fixedly attached to the ski 18. Between the locking piston 78 and the bearing part 72 'a height trigger 76 is also arranged. A side release backdrop is missing. Instead, the locking piston 78 has a flank 76 ‴ on which the projection of the bearing part 72 'determining the culmination point 94' can slide past the culmination point. The flank 76 ‴ is so inclined that an opening moment is exerted on the sole holder 64 as soon as the said projection has reached the flank 76 ‴.

The sole holder 64 in turn has a sole holding part 64 'and a step spur 64', the sole holding part 64 'being shorter in comparison to the first exemplary embodiment.

In addition to the sole or heel holder 64 designed only for a height release, a rotary member 118 is provided which is rotatably mounted about a ski-fixed vertical axis or vertical axis 46 and which in turn can be rotatably engaged with the ski boot 10 in order to define a defined axis of rotation of the ski boots. As in the first exemplary embodiment, the rotary member is chamfered at the ends to facilitate entry.

The vertical axis 46 is defined by a ski-fixed vertical pin 96, on which the rotating member 118 is placed.

In the rotating member 118, a slider 100 is guided in the area of the toe of the shoe which is displaceable in the longitudinal direction. At this outer, front end, the slider 100 is bent upwards to form a hook 110 and at a distance from the ski 18 back towards the heel. With this hook-like end 110, the slider 100 engages from the front a ski-fixed stop 106, which in particular comprises a transverse pin and is preferably designed in the form of a U-bracket.

The slider 100 is acted upon by a spring 102 in the sense of hooking with the U-shaped ski-fixed stop 106. For this purpose, the slide 100 with a rear, col ben-like section held against a front flattening 98 of the vertical pin 96. The spring 102 is supported on the one hand on an internal transverse wall 104 of the rotary member 118 and on the other hand on the front end wall of the rear, piston-like section of the slide 100.

The rotary member 118 in turn enters a recess 108 on the underside of the ski boot 10.

With a pivoting of the ski boot 10 and thus the rotary member 118 about the vertical axis 46, the slider 100 is moved forward due to the flattening 98 of the vertical pin 96, so that it has a hook-like end 110 to the side release laterally from the U-shaped, having a transverse rod Stop 106 is released. During such a pivoting movement of the boot, the hook-like end 110 of the slider 100 slides along the said crossbar until the subsequent side release. For this purpose, a corresponding rotational movement of the boot is permitted in the area of the heel cheek.
