Description

The invention relates to a ski binding according to the preamble of claim 1.

In a ski binding of this type known from AT-A-38 94 53, the front jaw is with an L-shaped support body mounted directly on the top of the ski or in a fixed one mounted on the top of the ski guide rail. A step plate on the support body or on the guide rail determines the standing height of the ski boot in the toe area. The coupling element connects the support body or the guide rail the toe with the heel. The heel cheek is movable held in a guide rail, which is firmly mounted on the top of the ski is. A cover is pushed onto the coupling element and with the guide rail of the heel cheek locked. The cover determines the height of the stand Ski boots in the heel area. The ski binding is because of the coupling of the sliding Heel cheek with the toe is technically complex and multi-part. The The standing height of the ski boot is normal, i.e. only as big as it takes to fix the ski boot in the ski binding is required.

In the case of the ski binding known from FR-A-2 654 636, the toe is without a stand-increasing Measure screwed directly to its base plate on the top of the ski, during the heel cheeks in a guide rail screwed directly onto the top of the ski is displaceable against the force of a pressure spring. The band-like Coupling element is firmly anchored at the front end. On the back end of the Coupling element is the heel shoe which can be moved in the guide rail a releasable lock mounted.

In the ski binding known from US-A-5 647 605, the toe is on one Mounted plate that can be tilted about a transverse axis in a ski-fixed base plate is supported by an elastic cushion. The heel cheek is on a slider mounted, which can be tilted about a rear transverse axis in a ski-fixed base plate and is supported by an elastic cushion. Behind the toe and in front the heel cheek is one with the tiltable plate or the tiltable Sensor plate connected slider provided. The one between the front and the Heel-clamped ski boots stand on the sensor plates, which are under controlled Toe pressure or heel pressure together with the front and heel cheeks giving way relative to the ski. The tiltable plate and the tiltable mounted sliders are additionally supported via articulated handlebars between them a longitudinally extending strut extends. About the handlebar arrangements and the strut can be controlled while skiing by controlled toes and / or Heel pressure pushes or relieves the ski ends in the snow.

In the case of the ski binding known from EP-A-0 620 350, FIGS. 3 and 4, the front jaws are and the heel cheek mounted on a common, tensile plate, which in the The toe area is fixed to the ski. The heel cheek is relative to the plate longitudinally adjustable. Below the plate are front and rear, stand-increasing plates built-in, the front plate being firmly anchored, the rear plate, however is guided in the longitudinal direction of the ski. The rear end of the cheekbones Plate is slidably lifted off the ski. At the very back is one cushioning cushion placed under the plate.

In the case of the ski binding known from EP-A-0 514 837, the toe is with its Base plate fixed on the top of the ski, while the heel cheeks in one on the Ski top fixed guide rail is slidable. The coupling element is in hooked the toe and coupled with the heel to adjust the length In one embodiment, the coupling element is connected to the front jaw limited longitudinal adjustment against spring force.

Not only in racing, but also with the increasing among normal skiers Carving trend is increasingly a much larger than the normal height of the stand Ski boots needed on the one hand at extreme inclinations of the skiing technique Has advantages and on the other hand larger lever arms for those from skiers in the Ski-initiated taxpayer allows. There are various stand-up types for this Measures known.

The invention has for its object a ski binding of the aforementioned Specify type that is structurally simple for the ski boot with a significantly increased standing height avoids unsuitable ski stiffening with longitudinal heel cheeks, whereby the ski binding can be adapted to all common ski boot sizes and an easy way to retrofit simple and inexpensive ski bindings given with regard to greater standing height and movable heel cheek should be.

The object is achieved with the features of claim 1.

The heel cheek and the toe cheek, which in themselves are not necessarily in view to a significantly excessive standing height and longitudinal mobility of the heel cheek must be designed, are mounted on the ski using the binding plates, that the desired significantly increased standing height and the mobility of the heel cheek are given, which prevents inappropriate stiffening of the ski. It can handle practically any heel-to-toe jaw combination, even the cheapest, be inexpensively retrofitted or modified for sophisticated driving demands. The The overall height of the binding plates is used profitably to include fastening devices, Movement guides or moving components of the additional To accommodate functions. The ski binding is easy to manufacture and therefore inexpensive in their manufacture. It consists of few individual parts because of the binding plates perform multiple functions. The longitudinal guideway, which is the longitudinal displacement of the heel cheek for ski deflections is within the Height extension of the binding plate housed. This is how the thickness of the binding plate can be profitable use and become exposed, relatively movable to each other Components avoided. The large height within the binding plate allows the movement control to be designed very stable, which is the driving behavior and the service life benefits. The heel shoe is either with its guide rail or only mounted on the support insert with a base plate which is in the guideway of the Binding plate is slidably guided. The coupling element does not need on the heel cheek attack, but is directly coupled to the carrying insert, which is dependent on the size of the ski boot Distance between the toe and the heel comply. Alternatively, parts are saved if the guide rail of the heel shoe led directly in the longitudinal guideway of the binding plate and, so to speak, in this is integrated. The longitudinal movement of the guide rail avoids unwanted Ski stiffeners for ski deflections.

According to claim 2, the binding plate of the toe is at a fixed Position of the ski mounted. Boot size-dependent mounting positions for the toe pieces on the binding plate allow easy adaptation to the respective Ski boot.

According to claim 3, the support insert is arranged so to speak sunk in the binding plate. Its longitudinal movement play within the binding plate avoids unwanted Ski stiffeners for ski deflections.

According to claim 4 can be in interaction with the various mounting positions corresponding for the toe piece on the binding plate of the heel piece Select the relative positions of the heel cheek depending on the size of the ski boot.

According to claim 5, the guide rail of the heel shoe has an expanded Adjustment range so that all common ski boot sizes can be covered. The guide rail not only leaves the thrust adjustment for the heel cheek make it comfortable, but also the respective one that corresponds to the size of the ski boot Positioning the heel cheek.

According to claim 6 are on the toe binding plate and / or the support insert or the guide rail for the heel cheek multiple points of attack for that Coupling element provided. By selecting suitable attack points it is easy to adapt the ski binding to different ski boot sizes make. As an alternative, it would be possible to adjust the coupling element lengthways train, or attachment points for points of attack between the coupling element and the front binding plate or the support insert or the guide rail of the heel cheek on the coupling element adjustable to despite the adjustability with a fixed point of attack on the front binding plate and the support insert or the guide rail.

According to claim 7, the thrust adjustment can be made on the guide rail the heel cheeks, but no significant adjustments can be made of heel cheeks on ski boot sizes. These settings are, however, made via the coupling element.

Alternatively, according to claim 8, the heel cheek is in only one mounting position the support insert, and the support insert can be adjusted by adjusting the coupling element or adapt its point of attack to the respective ski boot size.

According to claim 9, the coupling element is structurally simple and reliable.

According to claim 10, an unintentional pulling out of the support insert or avoided the guide rail from the binding plate for the heel shoe. thanks Appropriate clearance spaces will result in undesirable ski stiffening during ski deflections locked out.

The front and heel cheeks are particularly useful according to claim 11 Commercially available and inexpensive binding parts that can be installed directly on the top of the ski are determined, but according to the invention the advantage of the stand-increasing Use binding plates and the coupling element.

To trigger the release of the ski binding parts as desired to leave, should be provided according to claim 12 sliding plates on the binding plates be either molded in one piece or additionally used.

On an alpine ski S a ski binding B is mounted in FIGS. 1 and 3, which in itself two additional functions for skiers fulfilled for the safety-triggering definition of a ski boot, not shown. On the one hand the ski boot is in ski binding B with a significantly increased standing height above the top of the ski (the distance between the bottom of the ski and the bottom of the ski boot can be up to 5 or 7 cm), for example when carving undesirable collisions of the ski boot with the To avoid snow, and to control the foot or leg of the skier to bring to the ski edges with significantly enlarged lever arms. On the other hand in the ski binding area an undesirable stiffening of the Ski S with positive and negative ski deflections avoided.

The ski binding B has a toe V and a heel F, which both of a commercially available, intended for direct mounting on the top of the ski, inexpensive ski binding can belong, but do not have to. Under the toe V and the heel F there is one on the top 6 of the ski stand-increasing binding plate P1 or P2 with fastening devices 7, 12 permanently installed.

On the binding plate P1 is the toe V with a base plate 1 (or one Guide rail) at a mounting position 3 with fastening devices. On the surface designated by 4 of the binding plate P1 are in the longitudinal direction of the ski distributes several mounting positions assigned to different ski boot sizes 3, 3 'provided or possible. The lower surface of the binding plate designated 5 P1 suitably sits directly on the top of the ski 6. With regard to the least possible stiffening of the ski S in the binding area is the Bottom surface 5 shorter in the longitudinal direction of the ski than surface 4.

On the rear binding plate P2, which is similar to the binding plate P1, the heel jaw F is with its guide rail 8 or a base plate in a mounting position 9 with fastening devices, specifically in FIG. 1 and 3 on a plate-like support insert T, which is in the binding plate P2 in a Longitudinal guideway B guided in the longitudinal direction and against lifting is secured upwards. For example (Fig. 3), the support insert T has lower, laterally projecting guide rails 20, which project upwards by inwardly projecting Flanges 14 are covered. The support insert T is considerably longer than the guide rail 8 of the heel shoe, which is essentially only a longitudinal adjustment of the Heel cheek allows for thrust adjustment. To adapt to different Ski boot sizes are several mounting positions 9, 9 'on the carrying insert T. Heel cheeks provided or possible.

When the Ski S is relaxed, the longitudinal guideway B is in front and behind the support insert T clearances 13 is provided, the longitudinal movement of the Determine the insert T in the longitudinal guideway B, relative to, if necessary provided end stops 24 of the longitudinal guideway B (Fig. 2).

A longitudinally stable coupling element K, e.g. a band 15 with both ends pointing upwards Hook 16, connects the support insert T with the binding plate P1 for the toe cheeks V. The connection is established between each point of attack 17 in the binding plate P1 and a point of attack 19 in the support insert T. On this With positive and negative ski deflections, the manner shown in FIG relaxed position of the Ski S ski stiffeners avoided because of the carrying insert T moves in the longitudinal guideway B as part of its longitudinal movement play, and still the set distance between the heel and the toe remains adhered to.

In Fig. 1, the top of the support insert T is approximately flush with the surface 10 the binding plate P shown. The support insert T could, however, also slightly protrude above or even be sunk further relative to the surface 10 as shown. The binding plate P2 is with its lower surface 11 directly on the top of the ski 6 fixed, with fasteners 12th

In Fig. 3 (and Fig. 4) the binding plate P2 is the same width as the ski S. The binding plates P1, P2 could, however, also be narrower and / or diverging upwards or be designed to be convergent.

In the embodiment of FIGS. 1 and 3, the distance depends on the size of the ski boot between front and heel cheeks V, F adjusted with the help of the different Mounting positions 3, 3 ', 9, 9'. The distance between the binding plates P1, P2 cannot be changed, as well as the relative position of the support insert T in relation to the binding plate P1.

In the embodiment of FIGS. 2 and 4, the binding plate is P1 and the mountability of the toe V on this binding plate P1 as in Fig. 1, and therefore Not shown. In contrast to the embodiment in FIGS. 1 and 3, in FIG. 2 and 4 the support insert T shown in FIG. 1 is omitted, and instead the heel shoe F with its guide rail 8 'directly in the longitudinal guide track B of the rear binding plate P2 mounted in such a way that the guide rail 8 'is longitudinally displaceable in the rear binding plate P2 is guided and in the relaxed shown in Fig. 2 Position of the ski S has a longitudinal movement play back and forth, with the least the relative movements of the heel cheek F at maximum positive and negative ski deflections are possible relative to the rear binding plate P2, without the guide rail 8 'being intercepted at the end stops 24. The Guide rail 8 'of the heel shoe F (see also FIG. 6) has a multiple function, because on the one hand they adjust the thrust of the heel cheek in a relatively small Setting range X allows, but also the setting of the position of the Heel cheeks in a longitudinal adjustment range Y to the respective Ski boot size allows and directly for the guidance of the heel cheek F in the Longitudinal guideway B ensures. The coupling element K is only at a single point of attack connected to the guide rail 8 '. Adaptations to different ski boot sizes take place, as mentioned, within the extended setting range Y the guide rail, which is significantly longer than the standard version 8th'. Latching means 21 are provided for these settings.

In FIG. 5 there are several mounting positions 3, 3 'for the toe piece on the binding plate P1 V provided or possible. In contrast to the aforementioned embodiments 5, the coupling element K is, for example, with the binding plate P1 can be optionally connected in several points of attack 17, 17 'by the hook 16 is brought into engagement in one of the attack points 17, 17 '.

In the longitudinal guideway B of the rear binding plate P2 in FIG. 5 is the heel shoe F directly guided with a relatively short guide rail 8, this guide rail 8 only has the normal adjustment range X according to FIG Thrust adjustment is used. According to the different ski boot sizes in In this case, the coupling element 15 in a suitable point of attack 17, 17 'in the binding plate P1 attached.

So that the heel cheek F can be positioned according to the size of the ski boot is, the short guide rail 8 in the longitudinal guideway B has not only the two ends Free space 13 available, but an additional longitudinal play 23, the the adjustment stroke of the heel shoe between the largest and the smallest ski boot size equivalent. In Fig. 5 is the heel shoe, e.g. in one setting for the largest ski boot size.

The coupling element K is with the hook 18 in the point of attack 19 with the short guide rail 8 firmly connected. Alternatively or in addition, however, could be used Increasing the range of variation or setting also several, optionally usable attack points 19, 19 'provided for the coupling element K on the guide rail 8 his. The locking devices 21 of the short guide rail are used for thrust adjustment 8 used.

Alternatively, Fig. 5 further illustrates an embodiment in which only one Mounting position for the short guide rail 8 or a base plate of the heel shoe F allowing relatively short support insert T 'in the longitudinal guideway B is slidably guided. In this case the heel jaw F is with its guide rail 8 (shown in dashed lines) on this short support insert T ', the additional in addition to the two-sided longitudinal movement free spaces 13 also the increased freedom of movement 23 in the longitudinal guideway B, by means of the coupling element K and several points of attack for this one adaptation to different Ski boot sizes allowed.

In Fig. 5 it is indicated that on the binding plate P1 (as well as on the binding plate P2, not shown there) attached a slide plate 22 for the ski boot or can be molded in one piece.

Fig. 6 is a top view of the elongated guide rail 8 'of Fig. 2, which allows thrust adjustment and adjustment of the position of the heel shoe for different ski boot sizes. Dashed line, the short guide rail 8 is indicated ACCORDING _ß Fig. 5, which needs to allow only the thrust adjustment within the adjustment range X, as for adaptation to the respective ski boot, the guide rail 8 without this total displaceable in the longitudinal guide track by varying between the engagement points 17, 17 ' and / or 19, 19 'of the coupling element 15.

Instead of several different points of attack 17, 17 'or 19, 19' for the coupling element K or its hook 16, 18, the coupling element K in itself be designed to be variable in length, for example by the hook 16 and / or 18 are displaceable along the band-like coupling element K. Then would with a point of attack 17 or 19 in the binding plate P1 or on the guide rail 8 or the support insert T '.

The binding plates P1, P2 could be made of different materials or combinations of materials exist, e.g. made of plastic, wood or metal, in particular Light metal. The coupling element K is so far only as longitudinally stable and with band-like Character characterized. Since the coupling element K only pulls when skiing it only needs to be tensile while it is in the direction of pressure could be compliant. It is a band-like structure not absolutely necessary, it might as well be a rail or one Trade cables or a pair of cables (Bowden cable), similar to the brake cables on one Bicycle, and even easily adjustable in length.

1 and 2 is a movement space inside the rear binding plate P2 indicated for the coupling element K. The binding plates P1, P2 do not need how drawn to be massive, but could certainly be as hollow structures be trained, or have removable covers to make adjustments or to allow easier access to the inside for assembly. To assemble the shafts open to the top could be formed. The different mounting positions 3, 3 ', 9, 9' could be pre-made hole patterns, but not required holes could be closed by easily removable plugs. Finally, it is conceivable to make each binding plate P1, P2 from several separable ones Form layers or layers so that the skier or binding fitter different Choose stand heights or change the stand height.
