Abstract

The ski boot binding (11) has a leading section (13) with a pad (113) to grip over the toe of the boot, and a trailing section (15) with a rear pad (41) to grip the heel of the boot. The trailing section for the heel is on a slide (23), which rides on a guide (21) on the longitudinal line (25) of the binding against a spring, which allows the gap between the heel and toe sections to be increased if there is a twisting force on the boot. A swing unit (39) at the heel section can pivot around a lateral axis (67) against a second spring, to give a release action in the event of a forward fall.

Description

The present invention relates to a ski binding, in particular a Touring ski binding according to the preamble of claim 1.

DE-OS-1 428 974 shows a safety binding in which on with a Guide shoes provided basic body a guide piece longitudinally displaceable is arranged. On the guide piece a safety member is hinged pivotally. The safety member is a one-armed lever, on which a sole holder is attached, which can take the heel of a ski boot in engagement. Of the Lever has a groove in which a deep draw is inserted, which serves as a pressure spring serves. The deep train is led in holders, which at the side edges of the ski are mounted. By adjusting the depth train, the pressing force can be so adjust that paragraph both when twisting to both sides even when taking off with safety slides off the sole holder.

In a further embodiment shown in DE-OS-1 428 974 is in a basic body a bolt slidably mounted in the binding longitudinal direction. The bolt is biased by a spring. The spring is supported on the one hand on , Founding body and on the other hand screwed onto a bolt on the other Adjusting nut off. By adjusting the adjusting nut can on the bolt acting spring force to be changed. At the front end of the bolt, which is oriented towards the shoe heel is an arcuate shoe sole pad provided, which rests in use on the edge of the shoe sole. At the another protruding from the main body end of the bolt is a locking lever articulated, which rests with an extension piece on the base body. By Pivoting the locking lever, the bolt can be withdrawn. at closed binding, the spring ensures a contact pressure, thus the shoe held in the binding. In a spin fall, in which a force across the Longitudinal direction of the binding is applied, the bolt is pushed back, so that the ski boot can slide out of the binding. This embodiment of the Ski binding only allows lateral release of one in the binding clamped ski boots, as the shape of the sole holder lifting a in the binding clamped ski boot up impossible. In addition the skier has to bend over when getting into the binding, which as is considered disadvantageous.

In a more developed embodiment, therefore, that is against the shoe rounded end of the bolt, and the sole holder is firmly on the heel the ski boot attached. The sole holder has a spherical cap, in which the rounded end of the bolt can engage. This evolved Embodiment has the advantage that a triggering of the security bond is ensured both in a crash and a forward fall.

FR-A-2087723 discloses a ski safety binding with a Binding front part and a binding rear part. Binding front and - rear are each with a freely rotatable about a vertical axis wheel equipped with complementary, provided on the soles Counterparts can interact positively. While that Bonding front part is arranged stationary, the binding rear part is as Trigger part formed. The trigger part has one stuck on the ski arranged binding body, in which one in the axial direction opposite to Force of a spring displaceable housing 10 is provided, in which the rear wheel is rotatably mounted.

The described bond has the advantage that a clamped in the bond Shoe with appropriate force both at a turn fall sideways as well as in a forward fall up from the bond can get free. By choosing the shape of the interacting wheels and Counterparts, the characteristic of the safety bond can meet the needs be adjusted exactly.

According to another embodiment, the binding body is on a in the Section C-shaped rail slidably arranged in the longitudinal direction. The Location of the binding body on the ski is fixed by means of a rail arranged adjusting screw in the longitudinal direction in certain positions fixable, so that the binding is adapted to shoes of different sizes can be. To open the binding of the binding body by means of a Operating lever to be moved backwards. Although the binding In comparison to previously known bindings can have advantages, it has in practice never be able to enforce.

A disadvantage of the described binding, for example, that shoe and Bond must be coordinated, i. a commercially available one Shoe would first have to be equipped with counterparts so that the Security binding can work. Moreover, the bond is in the Production relatively expensive and therefore expensive.

EP-A-1 027 908 describes a binding heel piece having a base part, a Sole pad for a shoe and a mobile jaw for holding a Ski boot. The jaw is along a cylindrical column opposite to the Spring force of two springs substantially vertically movable. According to the teaching However, EP-A-1 027 908 of the jaws is not only vertically movable but he can also rotate about a substantially vertical axis. To this Purpose is provided in a round hole of the base part, a rotary member on which the column is arranged. The rotating part has a flat end, on which a with a spring preloaded ram is applied. The tension of the spring is with help a screw adjustable. In the case of a laterally acting on the cheeks Torque can counteract the rotating part with the pillar and the jaws turn the flat end of the rotary part acting spring force and a shoe release. The bond of EP-A-1 027 908 has the advantage that the Bindungsfersenteil both a release of the ski boot in a rotary as also allows a forward fall.

By the DE-A1-197 03 55 a touring binding is disclosed which a Touring frame has that held about a pivot in a bearing block pivot axis is pivotally mounted. In operation, a ski boot on the touring frame between a front sole holder and a heel holder by a Clamping spring clamped. The heel holder is on the tour rack along a length compensation path against the spring force of the pressure spring slidably guided. The pivot axis of the touring frame is above the plane of the touring frame and between the pivot bearing of a toe strap and the front, the boot tip associated edge arranged. Through this Arrangement comes with a pivoting movement of the touring frame Boot tip on the area of the ski in front of the storage block, whereby to expect a limitation of the swing angle of the touring frame is. However, this Schwenkwinkelbegrenzung does not occur, because the boot at a further pivoting up to an angle of 90 degrees against the Effect of the pressure spring can be moved backwards. According to the The teaching of DE-A1-197 03 55 is the pressure spring as a soft Length compensation spring with a large spring travel and a small increase in force form over the entire suspension travel. The length compensation spring causes that during ascent, when the touring frame is not found on the ski, but is pivotable about the pivot axis, the boot over the Heel holder pressed against the front sole holder and thus in the binding is held. An additional function comes the Andrück resp. Length compensation spring not closed.

Describe the Schibindungen described above Safety binding concepts, in which a longitudinally arranged Compression spring with closed binding both for the necessary contact pressure ensures as well as a sliding out of the ski boot from the binding in a Drehund Forward fall allows. Although the bindings are relatively easy to manufacture and these are the risk of injury both in a turnaround and in To help alleviate a forward fall, these bond types have become more important in the Market can not prevail. In contrast to the initially described Solutions have modern security bindings a tie front, which in a transversely acting to the binding longitudinal force Sliding out of the ski boot against a spring force and at the same time remaining distance between the binding front part and the Heel holding device by pivoting the binding front part enable.

Object of the present invention is that described above generic bonds continue to improve. In particular, it is a goal to provide a ski binding, which consists of few parts and in the Production is inexpensive. Another goal is a bond which is simple in construction, but nevertheless for the necessary driver safety ensures. Yet another goal is to provide a bond which allows easy boarding. In addition, there is an objective that commercial ski boots without any modifications with the Ski binding can be used.

An inventive solution of a bond according to the preamble of claim 1 is characterized in that on the heel holding device for realization a forward lunge triggering device about a pivot axis transverse to Binding longitudinal direction and against the force of a second spring means pivotable heel part is provided on which the buttocks is arranged or molded, which heel part of an open position, in which is the distance between the toe and the buttocks relatively is enlarged to a closed position, so that a ski boot from the ski binding can be moved to a closed position swiveling or displaceable, in which is the distance between the toe and the buttocks relatively to open position is reduced by a certain amount, so a ski boot in the bond is held. In contrast to the aforementioned generic Schisicherheitsbindungen are for turnaround and Forward fall separate safety devices provided. This has the Advantage that, unlike the binding of FR-A-2 087 723, a modification of the footwear is not necessary. In addition, by the inventive Concept realized a step-in binding, which allows easy entry into the Ski binding allowed.

It is advantageous in the closed position by the first spring means a Contact pressure on one in the bond between the toe and the Breeches arranged arranged ski boots. This can be done by it Achieve that distance between the toe and the buttocks in the closed position by a certain amount, preferably 1 to 2 mm, smaller is set as the actual distance between the front and rear Attack points of the front jaw resp. the buttock on the ski boot.

Basically, the abutment on the ski or at the Guide device to be arranged detachably and displaceably. This allows the Binding to be adapted to very different shoe sizes. Conveniently, however, the abutment on the guide device is fixed, preferably arranged at the rear end of the guide device. to Adjusting the ski binding to different shoe sizes can be one Adjusting device for changeable adjustment of the distance between the Abutment and the first spring means may be provided. This Adjustment conveniently has a relative to the abutment in Longitudinally displaceable first stop, one side of which at a first End of the first spring means and the other side of the slide is applied in such a way that a forward movement of the carriage relative to the abutment makes it impossible to reverse the carriage against the spring force of the carriage However, first spring means is possible. In an advantageous embodiment is the adjustment by a screw, which screw with a End supported on the abutment, and screwed onto the screw shank, formed as the first stop serving mother.

Advantageously, a device for variable adjustment of the carriage Provided spring compression of the first spring means. By setting the Spring tension, the release force of the bond can be adjusted. The Setting device for the spring tension expediently engages the second End of the first spring means on. Basically, the abutment is not conceivable behind the sled, but in front of the sled. Also, the Adjusting device for the spring tension at the same end of the spring attack as Adjustment device for adjusting the binding to different Shoe sizes. The adjustment device for the spring tension has the function to shorten the travel of the first spring means and thus the bias to increase. This task can be accomplished by different arrangements and means be solved. Advantageously, the adjustment by a relative to Slide longitudinally displaceable second stop formed to the Adjust spring tension. In an expedient embodiment, the second stop a nut or a stop plate, which on the shaft a screw is screwed, which screw itself with the head on the slide supported.

Conveniently, at a distance from the buttocks a tread spur at the bottom End of the heel part provided. Through the tread spur is a Einsteigehilfe in realized the bond. It allows a closure of the binding, without the Skier would have to bend over.

According to a further aspect of the invention, the binding is characterized in that the carriage is provided with an upwardly extending housing part for receiving the second spring means,
that the housing part at the upper end has formed a boundary, for example in the form of a housing cover, for the second spring means;
that in the housing part, the second spring means is arranged;
that the heel part has formed a slot at the top and is placed on the housing part; and
that an adjusting screw passes through the slot and holds the spring means under a certain bias by means of a nut screwed onto the shaft. It is also conceivable, however, that the heel part engages by means of driving cams, which protrude through longitudinal slots in the housing part, directly on the compression spring. In this case, no slot would be necessary in the heel part, but the adjusting screw for generating a variable bias could be placed directly on the housing part. However, there are known in the art still further Vorsturzsturzauslöseeinrichtungen, which can be provided on the carriage.

Further, the heel part preferably has an upper guide portion for the Receiving an upper portion of the housing part, which for a coaxial Guiding the heel part relative to the housing part provides. In addition, to Enabling pivoting of the heel part to the rear at the top Guide section one shoulder - widening the guide section to the front - connect.

In an expedient embodiment, an actuating lever is on the heel part hinged, which is supported on the carriage and a manual lifting allows the heel part against the spring force of the second spring means. In front the heel part may be provided a rear sole pad, which in Spaced apart ribs, preferably in Binding longitudinal direction extending longitudinal ribs or arcuate ribs has. The ribs have the function in connection with the Spring-loaded buttocks for a good hold of the shoe heel to care. When in the closed position, the ribs the tread spur of the heel part overshoot by a certain amount, this has the advantage that shoe soles different thickness with a top pressure acting can be applied.

Characterized in that both the binding front part and the heel holding device as also the toe and the buttocks in each case with respect to a vertical On the binding base standing axis are arranged rotationally fixed, is a given simple construction. Basically, the angle between the Front cheek wings and the binding longitudinal axis be adjustable to the Adapt binding to different shoe shapes and sizes. In the Once set position but the front jaw wings with respect to a Be sure to swivel outward.

The toe piece can, for example, V-shaped front cheek wings exhibit. The orientation of the guide surfaces for the ski boot at the Turnstile release serving forehead wing has a direct impact on the tripping characteristic of the binding. The front jaw wings have expediently at least one substantially straight end section, which can laterally engage a ski boot tip. Through the straight End sections is one with the rounded shell of a clamped ski boot is formed substantially vertically extending contact line. It turned out to be proven advantageous when the straight extensions of the Vorderbackenflügelendabschnitte together include an angle α, which between. 80 and 120 degrees, and preferably between about 95 and 115 degrees.

The front jaw wings are expediently designed such that the translational release path of the displaceable binding part between 4 and 9 mm, but preferably between 5 and 7 mm or above. To the Front jaw wings may be provided with sliding bearings, rollers or the like, on which the ski boot can support itself. Through the plain bearings or rollers the frictional resistance can be reduced during the turnstile release. in the In contrast, the buttocks can be circular or arcuate his.

Advantageously, the guide means by two preferably round Guiding bars formed. Two guide rods make a sturdy binding realizable. Conveniently, the guide means is one Swivel axis transversely to the longitudinal extent of the binding pivotally and in Area of the binding front part hinged to the ski. Such a bond can also for ski touring, especially touring, used. Conveniently, the binding front part has a U-shaped Mounting bracket, on whose legs the guide device is articulated. Also, on the U-shaped mounting bracket, a front sole holder or To be hinged to the front jaw. The toe is located expediently with a stop lug on the guide device and is biased by a spring against the guide means.

It is advantageous on the toe one transverse to the longitudinal axis of the bond slidable sliding plate provided on which one in the binding restrained ski boot can rest. The sliding plate has the purpose of the Friction resistance during lateral sliding out of the ski boot from the Reduce or at least keep constant binding during a turnaround.

Conveniently, only a single carriage is provided, the Heel part is part of the heel holding device. Advantageously, the slide and the heel part each formed in one piece. This can make the bond off only consist of few items. The bond is advantageously substantially off Plastic, a plastic fiber composite or one Carbon fiber composite made. The inventive bond has the Advantage that they only two springs for the realization of a lintel and a Frontal fall release device required. In addition, with the spring for Rotary lane release at the same time a contact pressure in the binding longitudinal direction, and with the spring for the frontal fall trigger a contact pressure from above on the Shoe sole be exercised. Accordingly, the inventive requires Binding only two compression springs. The toe wings and the first and second buttocks are preferably designed so that in a twist fall a relative displacement of binding front and Heershaltevorrichtung order at least 4 mm, preferably at least 6 mm, and especially However, preferably between 5 and 7 mm (= trip distance) is necessary so that the Shoe is released from the binding.

The first embodiment shown in FIGS. 1 to 12 Shaft binding 11 according to the invention, which can be used as touring ski binding has a binding front part 13 and a heel holding device 15. Binding front part 13 and heel holding device 15 are at a distance from each other on a ski 17 (see Fig. 9 and 13) can be arranged. Between the The binding front part 13 and the heel holding device is a receiving space 19 for a ski boot 20 (Figure 9). The heel holding device 15 has a Management organ resp. a guide device 21, which when mounted binding is arranged on a Schi 17 non-displaceable. On the guide device 21 is a carriage 23 slidably guided in binding longitudinal direction (arrow 25). The Guide device 21 consists of two in the embodiment shown parallel, spaced apart guide rods 27a, 27b, which are preferably designed as round rods. However, it is also conceivable instead of using two guide rods only one guide rail.

The guide rods 27a, 27b are at one in the region of the binding front part 13th arranged, transverse to the binding longitudinal direction 25 pivot axis 28th pivotable. By pivoting a walker is created, which the skier walking, in particular going uphill, facilitates and ensures the necessary freedom of movement. With the Guide bars 27a, 27b are the binding front 13 and the Heel holding device 15 connected to each other and opposite the ski pivotable.

The slidably mounted on the guide device 21 carriage 23 is from a side view L-shaped housing 29 (Figure 4), and a arranged on the heel part 39 (FIG. 5). The one leg 31 of the housing 29th has sliding guides 33, which of the guide rods 27a, 27b are interspersed. The other of the carriage 23 upstanding housing part 35th of the L-shaped housing 29 has a cavity 30 which receives a Compression spring 37 (see Fig. 9) is used. The compression spring 37 serves on the one hand as Trigger spring in case of a forward fall and on the other hand in the Closure of the heel holding device 15 for the necessary contact pressure of Ensure ski boots perpendicular to the binding surface. The housing cover 44 of the Housing part 35 serves as a stop for the compression spring 37. In the housing cover 44th a passage opening 46 is provided for a set screw 55, as this will be described in more detail below.

A housing-like heel part 39 with a buttock wing 41a, 41b having rear jaws 41 for engaging a Schischuhabsatzes is on the leg 35 of the L-shaped housing 29 is placed. The heel part 39 has at the upper end a guide portion 43 for the positive reception of the upper portion of the housing part 35. The heel part 39 is through the Guide portion 43 in the direction of the longitudinal axis of the leg 35 (arrow 45, FIG. 2b) guided longitudinally displaceable. At the guide portion 43 then is on Heel part 39 a forward, i. towards the binding front part 13, oriented shoulder 47 is formed, which a pivoting movement of the heel part 39 relative to the housing part 35 releases (Figures 2 and 3). The shoulder 47 serves as Sliding surface, which in the open position of the heel part 39 on the housing part 35th rests.

The heel part 39 has a curved ceiling 51, in which a in Binding longitudinal direction extending slot 53 is provided. In the slot 53, a set screw 55 is inserted. The set screw 55 also penetrates the Passage opening 46 and accommodated in the housing part 35 compression spring 37th (Figure 9). The shaft 57 of the adjusting screw 55 is provided with a screw thread 59 provided on which a stop piece 61 (Figures 3a to 3c) is screwed. The stopper piece 61 engages the compression spring 37 and holds it under a certain bias. Through the slot 53 is the pivoting of the heel part 39 with respect to the housing part 35 limited. Through the back tilted extreme position of the heel part 39 is the open position of Heel holding device 15 is defined.

Below the rear jaw 41, a tread spur 63 is arranged on the heel part 39. In the open position of the heel holding device 15, the tread spur 63 is located in the trajectory of a ski boot to be clamped in the ski binding and thus allows the heel part by the weight of the skier of bring the open position in the closed position.

In the figures 2a to 2c, the movement of the heel part 39 at Clamping a ski boot shown. Figure 2a shows the Heel holding device 15 in the open position. The heel part 39 is opposite lifted the housing part 35 and tilted backwards. The wall 49 is in Stop with the upper edge of the housing part 35, and the shoulder 47 lies on the designed as a sliding surface 48 housing cover 44 of the housing part 35.

FIG. 2b shows a middle position in which the heel part 39 is lifted, and the guide portion 43 coaxially aligned with the elongated housing part 35 is. In this position, the guide portion 43 is above the arched Sliding surface 48. A pivoting of the heel part 39 from the open position in the Middle position is achieved by using the clamped ski boot on the Tread spur 63 is kicked. By thereby perpendicular to the tread porosity 63rd acting force is a torque about the axis 66 causes. It slides the Shoulder 47 on the sliding surface 48 to the front, and the heel part 29 is relatively pivoted to the housing part 35. Once the position shown in Figure 2b is reached and the shoulder is no longer resting on the housing cover 44, snaps the heel part 39 - due to the bias of the spring 3- - in the Closure position (Figure 2c). In the closed position take the buttock wings 41a and 41b engage the sole or heel of a ski boot. Preferably the vertical closing distance of the heel part is greater than the sole thickness of the heel piece to be clamped ski boot. Thus, the sole of the ski boot by the Buttocks pressed against the sole pad and in the assumed position be fixed.

For manual opening of the heel holding device (compare FIGS. 3a to 3c) is at the heel part 39, an actuating lever 65 hinged, which is located on the housing 35 is supported. The pivot point 67 and the shape of the actuating lever 65 is so chosen that upon actuation of the lever, the heel part 39 is raised and lowered is tilted back into the open position. According to the embodiment of the Anlenkpunkt 67 selected at a short distance to the tread 63, and the Operating lever 65 is supported by an edge 69 on one of the carriage 15th trained shoulder 71 off. The in the closed position at an angle Rear and top projecting actuating lever 65 has at the outer end a Recess 73 (Figure 14) into which a ski pole tip can engage. Will the Operating lever 65 pressed down, so the heel part 39 moves with the pivot point 67 upwards. The heel part 39 is tilted backwards, as soon as the shoulder 47 comes to lie on the sliding surface 48 of the housing part 35.

On the carriage 23 and in front of the housing part 35 is a rear sole rest 79th intended. The sole support 79 has several longitudinal and in Distance apart longitudinal ribs 81 (Fig. 6). Between the rear Sole support 79 and the housing part 35, a gap 77 is present, in which in the closed position of the heel holding device 15 of the tread 63th of the heel part 39 comes to rest. Housing part 35 and heel part 39 are preferably designed so that in the closed position the ski boot sole the spring-loaded buttocks 41a, 41b on the Sole support 79 is pressed. This has the advantage that the intake range between tread 63 and buttocks 41 greater than the strength of Shoe sole edge can be. As a result, sticky to the soles Snow layers less disturbing when entering the binding. The through the spring 37 applied contact pressure also improves the adhesion between Ski sole sole and sole rest 79.

To adjust the position of the carriage 23 on the guide rods 27a, 27b is a Screw drive 83 provided with a screw 85 (Fig. 9). The spindle 85 of the screw drive 83 is rotatable with its head 87 in an abutment 89 and stored deferred. The abutment 89 is non-displaceable on the Guide rods 27a, 27b mounted. On the screw 85 is a Attachment piece 93 screwed, which on the one hand on a carriage 23rd trained shoulder 90 is supported, but not firmly with the carriage 23 is connected, so that a Nachvorneschieben the carriage is impossible. On the other hand, the stop piece 93 acts with a arranged in the carriage Compression spring 95 together, which is also supported on the carriage 23. The Compression spring 95 is provided in a between the guide rods 27a, 27b Recess or a channel 97 (Fig. 6 and 7) arranged in the carriage 23. she acts with one end with the screw drive 83 and with its other end with the carriage 23 together. By the screw drive 83 is the minimum Distance between the binding front part 13 and the heel holding device 15 adjustable. An enlargement of the distance between the binding front part 13 and the heel holding device 15 (backward displacement of the carriage) However, with this device against the spring force of the compression spring 95 is possible.

For variable adjustment of the bias of the compression spring 95 is on the carriage 23rd an adjusting screw 99 is provided which the spring travel of the compression spring 95th reduce and thus increase the spring tension of the compression spring 95. The Adjusting screw 99 has a collar 101, with which they are connected to a Shoulder 103 of the carriage 23 is supported. On the screw shaft 105 with Screw thread 107 is a stop piece 109 screwed on, which on second, front end of the compression spring 95 is applied. By turning the Adjustment screw 99, the position of the stop piece 109 and thus the Bias of the compression spring 95 can be changed.

The binding front part 13 (see Figures 10 to 14) is at a distance from Heel holder 15 arranged. The binding front part 13 has a U-shaped Mounting bracket 108, which with mounted binding on a ski is fixed. In the bottom plate 110 of the mounting bracket 108 are countersunk round holes 112 provided in which for mounting the Bonding front part 13 screws not shown are used. To the Legs 114 of the mounting bracket 108 are the guide rods 27a, 27b to the Swivel axis 28 pivotally articulated. For this purpose is a fork-shaped coupling part 111 is provided, the arms 121 each one Passage opening 123 for receiving an axle pin 125 have. The Axle pins 125 for articulated connection of the coupling part 111 to the U-shaped Mounting bracket 30, for example, in the figure 12 can be seen. The Connection of coupling part 111 and the guide rods 27a, 27b takes place conveniently via a plug connection. The plug connection is formed by aligned guides 127 into which the guide rods 27a, 27b are used. Inserted in recesses 129 pins 131 fix the Guide rods 27a, 27b in the guides 127. At the rear end of Coupling part 111 is provided on the underside an extension piece 133, which serves as an additional support for the guide rods 27a, 27b.

At the U-shaped mounting bracket 108 of the binding front part 13 is next to the Clutch part 111, a toe jaw 113 with lateral front jaw wings 113a, 113b arranged pivotally. The articulation of the front jaw 113 via two spaced apart webs 135, which passages 137 for receiving an axle. As axis can be a continuous Achsstift 125 serve, with which also the coupling part 111 on the bracket 30th is articulated. At the bottom of the front jaw stops 139 are formed, which rest against stop surfaces of the coupling part 111. One not The spring shown holds the pivotable front jaw 113 in abutment with the Coupling part 111.

As can be seen in particular from Figures 1, 11 and 12, the Front jaw wings 113a, 113b a certain distance in front of the pivot axis 28th arranged so that the pivot axis 28 with clamped ski boot approximately in the area of the ball of the foot. This allows you to ski to get as natural a movement as possible. Is that the Toe 113 on the ski surface, so thanks to his Pivotable relative to the guide device 21 the Heel holder 15 still be pivoted forward because this on the guide device 21 against the spring force of the compression spring 95th is displaced to the rear.

On the relative to a vertical axis non-rotatably arranged toe is a sliding plate 119 slidable transversely to the longitudinal direction of the binding intended. On the slide plate 119 is located in a clamped ski boots the front end of the shoe sole up. The slide plate 119 is not shown by means Biasing springs into a center position. The front jaw wings 113a, 113b are in the height adjustable relative to the sliding plate. For this purpose, the Front jaw 113 preferably in two parts with a top 120 and a Lower part 122 realized. Between the upper part 120 and the lower part 122 is a Guide 124 is formed which a height adjustment of the toe wings allows (Figures 10 and 12). With an adjustment screw accessible from above 115 is the distance of the front jaw wings 113a, 113b to the slide plate 119th adjustable. The upper part 120 can by means of a not apparent in the figures Spring, which is supported on the lower part 122, biased against the adjusting screw his.

For releasably fixing the mounted on the guide device 21 Heel holding device in the lower pivot position is a Locking device 134 is provided, which is stationary and in the area of rear end of the guide device 21 is mounted on the ski. The Locking device 134 has a base plate 136, at the one Clamping lever 138 is pivoted about a pivot axis 141. At the Clamping lever 138 is a clamping shoulder 140 is formed, which the rear end the guide device can engage. For that purpose that is Abutment 89 equipped with an extension 132 which passes through the clamping lever 138 formed protrusions 134 can be engaged. In the extreme pivotal position of the clamping lever 138, i. if this on the ski rests, the extension 132 abuts the projections 134, so that a Pivoting the guide device 21 is impossible. The extension 132 and the projections 134 are formed or. arranged that in the extreme pivotal position of the clamping lever 138 at a desired pivoting the guide means 21 the clamping lever 138 against the ski, i. in the Clamping position, is pressed.

In a first pivotal position of the clamping lever 138, in which this of the Schioberfläche is slightly raised, a release position is realized. In this Release position is the clamping shoulder 140 outside the Trajectory of the extension 132, so that the guide device 21 with the Heel holding device 15 is free to pivot. By further pivoting can the clamping lever 138 in already pivoted guide device 21 a occupy second and third pivotal position, in which the clamping lever 138 in a second and third angle to the ski surface is arranged. In these Pivoting is the extension on transverse ribs 143 of the clamping lever 138th Abstellbar, so that a walker is realized when going uphill.

The second embodiment 11a of the invention shown in FIG Ski binding essentially differs from the first embodiment in that the heel holding device 15 is not relative to the binding front part swiveling, but firmly mounted on the ski. Accordingly, this is Bond 11a can be used primarily as an alpine ski binding. At this Alpinbindung is the guide device 21 less trained and on the ski fixed. The guide between the carriage 23 and the Leadership 21 may, but does not have to be the same as the tour version be educated. In particular, it is conceivable, the leadership between the carriage and the base plate, for example, by one with a groove to form a cooperative comb. Also is a kind Dovetail guide conceivable. In a simple embodiment is a Flat mounting plate provided, the side edge upwards and inwards is folded so that a guide for a trained on the sled comb is formed. As shown in Figure 14, the abutment 89 is directly on the ski 17 mounted.

The security binding according to the invention functions as follows: The Front jaw wings 113a, 113b and the buttocks of the heel part engage each at least on the side of the shoe coat and hold the ski boot in one Center position clamped in the ski binding. A twist of the boot around one Axis vertical to the binding base is only possible if the distance between the toe wings 113a, 113b and the butt 113 is enlarged. Thanks to the displaceability of the heel holding device 15 counter the force of the spring 95 is such an increase in the distance at a Shock fall possible under the effect of a certain minimum torque. In this case, the rotationally fixed front jaw wings 113a, 113b act as sliding guides for the ski boot. Under the effect of a torque that will Binding front part 13 and the heel holding device 15 pressed apart. If the torque is sufficiently large, the ski slides out of the binding. The release force is adjustable by changing the bias of the Compression spring 95 in the heel holding device 15th

The adaptation of the binding 11 to the shoe is preferably carried out so that the Upper part 120 of the front jaw 113 by means of the screw 115 to the height of Shoe sole is adjusted, in such a way that between sole and Front jaw wings 113a, 113b is given a vertical distance of about 1 mm.

In this way, the toe is not clamped in the vertical direction and can assist in the spin fall release by the slide plate 119th pivot sideways with little friction. The heel is preferred clamped by the heel jaw 41 in the vertical direction against the ribs 81, so that transverse forces occurring at the heel are transferred from the shoe to the binding can be. The occurring at the heel trigger on the heel The movement of the shoe is so small that it does not affect the release becomes.

The person skilled in the art will understand from the above description that instead of the Heel holding device 15, the binding front part 13 in the longitudinal direction slidably mounted on a guide means 21 may be arranged. Also is not necessarily required that either front or rear contact pressure from the top of the sole edge is exercised.

In an alternative embodiment of the invention, the side release be moved from the toe to the heel by the slide plate 119 and the V-shaped guide surfaces 113a, 113b on the paragraph resp. Buttocks 41, ribs 81 and a prestressed in the vertical direction Back 113, however, on the toe, respectively. Binding front part provided are. Accordingly, in this embodiment, the height of the V-shaped To adjust guide surfaces having rear jaw so that between the Buttocks and the shoe sole a small gap is present. Of the In this case, the toe piece could be formed, e.g. in the form of one swivel bracket, that with clamped ski through the shoe Contact pressure of the compression spring 95 of the pivotable bracket to the toe the sole pad presses. Basically, the contact pressure of the Baking but also by a specially designed compression spring be generated.

The binding according to the invention has at least one binding longitudinal direction (Arrow 25) extending guide device and one on the Guide device arranged, slidable in the longitudinal direction slide. In In the preferred embodiment, the heel holding device is on the Sled arranged. The carriage is against the spring force of a first Compression spring slidable by one trip distance. The binding front part and the Heel holding device are arranged rotationally fixed, so that in a fall of the Schischuh by increasing the distance between the binding front part and the heel holding device is released. At the heel holding device is to Realization of a forward lunge triggering device about a pivot axis transverse to the binding longitudinal direction and against the force of a second compression spring pivotable heel part provided.
