wobei die Stütz- und Riegelanordnung schieberförmig ausgebildet ist und am weiteren Lagerteil zwischen der vom ersten Lagerteil entfernten Freigabelage und der zumindest einen, in Richtung des ersten Lagerteils vorgeschobenen Stützlage verschiebbar ist.The invention relates to a tour suitable ski binding with

• a support plate assembly which is pivotally mounted at its front end to an at least substantially skifest attachable or arranged first bearing part about a transverse axis and shoe holder for fixing an insertable into the shoe holder shoe or receives, and
• a supporting and locking arrangement mounted on an at least substantially skifest mountable additional bearing member cooperating with the hinge axis distal end of the support plate assembly or an end piece located there and pivoting the end or tail in a release position relative to the transverse axis, in a locking position to be locked on the further bearing part and supported in at least one support position with vertical distance from the further bearing part,

wherein the support and locking arrangement is formed slide-shaped and is displaceable on the further bearing part between the release position remote from the first bearing part and the at least one, in the direction of the first bearing part advanced support position.

Such a ski binding is the subject of DE 37 02 149 A1.

In a binding shown in EP 0 724 899 B1, the support or locking arrangement is designed as a pivoting lever which is arranged to be pivotable about an axis parallel to the transverse axis of the support plate arrangement on the further bearing part and lockable in different positions. When the pivot lever assumes its one end position in which its free end points in a direction away from the first bearing part, the support plate arrangement can be lifted under pivoting about the transverse axis in the region of its front end of the ski or hang up on the ski, so that a harmonious running motion , possibly also with skating steps.

Once the pivot lever is pivoted from the aforementioned end position when placed on the ski support plate assembly in a first detent position, the pivot lever facing the end of the support plate assembly is vertically locked, so that the support plate assembly is fixed substantially skifest. Thus, the skis can be driven in for the downhill or slalom race usual technique.

When the pivot lever from the aforementioned, the support plate assembly releasing end position is sufficiently far pivoted at sufficiently raised or upwardly pivoted support plate assembly in a further detent position, the pivot lever engages under the facing end of the support plate assembly with a first support, so that the schwenkhebelseitige End of the support plate assembly is supported at a predetermined vertical distance from the ski top side and prevented from further approaching to the top of the ski, wherein the support plate assembly from the support of the pivot lever remains liftable. In this way climbs can be made easier on tours.

According to EP 0 724 899 B1, a total of three latchable support positions are provided for the pivot lever, i. the pivot lever can pivot beyond the last-mentioned detent position into two further detent positions in which the support lever is supported with corresponding stops the facing end of the support plate assembly in even greater vertical distance from the ski top, so that even very steep climbs can be relatively easily committed.

In this known ski binding in the locking position of the pivot lever, so if the pivot lever is to fix the support plate assembly in the vertical direction on the ski, a greater play between the pivot lever and the facing end of the support plate assembly occur. Since the support plate arrangement has a greater distance from the neutral bending plane of the ski, the end of the support plate arrangement remote from the first bearing part, inevitably performs longitudinal movement relative to the ski upper side during flexing movements of the ski. Accordingly, the pivot lever must provide the facing end of the support plate assembly in its control position sufficient clearance.

The object of the invention is therefore to provide a tour suitable ski binding, in which a good handling is given and the support and latch assembly and the support plate assembly can cooperate with a fixed support plate assembly backlash.

This object is achieved in a ski binding of the type specified in that a spring arrangement pushes the slider-shaped support and latch assembly after unlocking previously depressed in a position on the second bearing part support plate assembly in locking engagement with the facing end or tail and pushed pushed in this position which lies between the release layer and the at least one support layer.

A special feature of the invention is that the locking position between the release position and the at least one support layer of the support and latch assembly is located. This is in conjunction with a spring assembly that seeks to push the support and latch assembly forward, the possibility created to keep the support and latch assembly pushed in the locking position constantly on the support plate assembly. With flexing movements of the ski, there are thus no relative movements between the support plate arrangement and the support and locking arrangement.

In this context, on the one hand there is the possibility of the support and locking arrangement when locking the support plate assembly to lock on this, so that a positive connection is given, which keeps the support and latch assembly always in a desired position relative to the locked support plate assembly.

Additionally or alternatively, it may be provided that the slider-shaped support and locking arrangement is tensioned by means of spring arrangement constantly in the direction of the first bearing part and locked in the release position against displacement in the direction of action of the spring assembly or lockable.

So as soon as the support and latch assembly from the release position in which the support plate assembly can be lifted on the one hand from the ski top and placed on the other hand on the Skioberseite is triggered, brings the spring assembly, the slider-shaped support and locking arrangement previously depressed against the ski top side support plate assembly in locking engagement with the facing end or tail of the support plate assembly, wherein the spring assembly pushes the support and latch assembly constantly against this end or end and pushed pushed.

Moreover, the aforementioned spring arrangement, the slide-shaped support and locking arrangement at previously slide vertically from the second bearing part or the Skioberseite sufficiently remote support plate assembly in a predetermined stop by end stop, in which the support and locking arrangement facing the end or end piece of the support plate assembly a support engages under.

Here, therefore, the spring assembly also has the function of a control unit, which allows to automatically set the support and locking arrangement in a supportive position.

Preferably, a stop device is provided with a plurality of stop positions, which are assigned to different heights of the support and locking arrangement.

In this case, the stop device may be associated with a handle that holds the lower support associated stop position effectively when not in use can be.

In a particularly advantageous manner, is claimed for the independent protection, it can be provided that the support and latch assembly is associated with a positively coupled with their movement handle, the movement of the support and latch assembly in the direction of the support position or support positions a vertical movement, in particular an upward movement, executes. By now on the handle, for example by means of a ski pole, a force is exerted in the opposite direction, the support and latch assembly can be reset in the direction of the release position.

In particular, it may be provided to arrange two handles, which move in opposite directions, wherein the one handle for returning the support and locking arrangement in the direction of Release position is used while the other handle leads to an opposing movement of the support and latch assembly or to their unlatching or unlocking, so that the spring assembly can push the support and latch assembly in the direction of the bolt position or each next support position.

Moreover, reference is made to the claims and the following explanation of the drawing with regard to preferred features of the invention, are described in detail with reference to the particularly preferred embodiments of the invention.

Protection is not claimed only for expressly stated or illustrated combinations of features. Rather, the protection should refer to basically any sub-combinations of the aforementioned feature combinations.

According to FIGS. 1 and 2, a touring binding 2 is arranged on a ski 1, which is only partially shown. This has a front in ski longitudinal direction, Skifestes bearing part 3, on which a support plate assembly 4 is pivotally mounted about a transverse axis 5.

The support plate assembly 4 consists essentially of a stable base support plate 6, which is fixedly connected at its front end with a pivotable about the transverse axis 5 front piece 7 and at its rear end with an end piece 8, which in a manner shown below with a Stützund latch assembly. 9 interacts.

The front piece 7 is mounted on the bearing part 3 hingedly with great stability, so that the base support plate 6 is only able to perform pivotal movements about the transverse axis 5, but is prevented from rotating about a vertical axis.

On the base support plate 6, a shoe support plate 10 is arranged, which is pivotable relative to the base support plate 6 about a vertical axis 11 against an adjustable trigger resistance. At the shoe support plate 10 front and rear sole holder 12 and 13 are arranged, which can engage in corresponding recesses of the shoe sole of a ski boot, not shown.

The sole holders 12 and 13 are releasable, i. they release the shoe used when excessive forces are exerted between shoe and binding 2.

The front sole holders 12 are controlled by rotational movement of the shoe support plate 10 relative to the base support plate 6.

As soon as sufficient torques are effective between shoe and base support plate 6, the shoe, together with the shoe support plate 10, performs a rotation about the vertical axis 11. If the rotational stroke exceeds a range of elasticity, at least the sole holder 12 pointing in the direction of rotation is unlocked, so that it can fold away to the side and thus release the shoe.

The rear sole holder 13 release as soon as sufficiently large forces are effective on the shoe, which seek to lift the heel area of the shoe from the shoe support plate 10.

The support and locking arrangement 9 has a skifest arranged bearing part 14 which is designed as a sliding guide for a support and bolt slide 15 and this allows a translational movement in the ski longitudinal direction.

The support and bolt slide 15 is formed by means of a helical compression spring spring arrangement 16, which has a skifestes abutment on the bearing part 14 and a relative to the ski 1 movable abutment on the support and bolt slide 15, in the longitudinal direction of the ski forward, i. in the direction of the first bearing part 3 stretched.

On the end face facing the bearing part 3, the support and locking slide 15 has two locking lugs 17 (see also Fig. 6), which in the example of Fig. 1 and in particular 2 a step 18 formed on the end piece 8 as a counter-locking element overlaps, so that the support plate assembly 4 can not swing up from the position shown in Fig. 1.

1 to 4 two juxtaposed supports 19 are provided on which according to FIG. 4, the upwardly pivoted support plate assembly 4 with its end piece 8 can be supported when the support and locking slide 15 in a corresponding support position has been advanced in the direction of the first bearing part 3.

In the example of Figs. 1 to 4, a hinged support bracket 20 is still arranged on the supports 19, which can be folded from the non-use position shown in FIGS. 1 to 4 about a transverse axis 21, so that it continues the supports 19 vertically upward , Thus, the support plate assembly 4 can be supported vertically in a relation to the example of FIG. 4 elevated position.

In the example of FIGS. 5 to 9, a further, higher pair of supports 22 is arranged on the support and bolt slide 15, which becomes supportive when the support and bolt slide 15 is pushed sufficiently far in the direction of the first bearing part 3 when the support plate assembly 4 is pivoted up.

When the support and bolt slide 15 is sufficiently far backward shifted in the position of FIG. 3, the locking lugs 17 are ineffective, ie they are no longer in registration with the step 18 on the end piece 8 of the support plate assembly 4, so that the support plate assembly 4 can be pivoted about the transverse axis 5.

To adjust the various positions of the support and bolt slide 15 a pivotable about a transverse axis 23 double arm 24 is arranged on the bolt slide 15, the arms are each provided with a plate-shaped handle 25 and 26, to which a ski pole can be placed with its tip. The handle 25 associated longer, forward facing arm of the double-armed lever 24 carries a yoke-like transverse bar 27, whose ends protrude in the manner of a sliding block in link slots 28 which are formed in side panels 29 of the bearing member 14 and arranged as the bearing part 14 skifest.

The link slots 28 form in the longitudinal direction of the ski upwardly increasing ramps, so that the handle 25 associated arm of the double-armed lever 24 is pivoted clockwise upwards when the support and bolt slide 15 is moved in the direction of the first bearing part 3.

At the bottom, in Figs. 1, 3, 4 and 5 the right end of the slot slots 28 are preferably undercut recesses 30 are formed, in which the ends of the transverse bar 27 can be received in a substantially positive fit.

When the transverse rod 27 is located with its ends in the recesses 30, the support and bolt slide 15 takes the release position shown in FIG. 3, in which the locking lugs 17 of the Step 18 of the end piece 8 of the support plate assembly 4 are moved away and the support plate assembly 4 can accordingly pivoted freely about the transverse axis 5 upwards or lowered against the ski 1.

If now the handle 26 associated arm of the double-armed lever 24 is depressed, the transverse rod 27 is disengaged from the recesses 30. This has the consequence that the spring assembly 16 pushes the support and locking slide 15 in the direction of the first bearing part 3.

Assuming that the support plate assembly 4 was placed on the ski 1 prior to depression of the handle 26, the spring assembly 16 pushes the support and bolt slide 15 now in the locked position shown in FIGS. 1 and 2, in which the locking lugs 17 the step 18 overlap the end piece 8 of the support plate assembly 4 and thus hold the support plate assembly 4 in its resting on the ski 1 location. If the ski 1 performs flexing movements, the end piece 8 shifts on the ski upper side in the ski longitudinal direction, because the support plate arrangement 4 has a more or less large vertical distance from the neutral bending plane of the ski 1. This movement of the end piece 8 in the longitudinal direction follows the support and locking slide 15, since it is constantly pushed in the locked position of FIGS. 1 and 2 of the spring assembly 16 against the end piece 8. During this sliding movement of the transverse bar 27 moves more or less far in the upward or downward direction in the slotted slots 28th

To return the support and bolt slide 15 back to its release position of Fig. 3, the handle 25, preferably with the ski pole, depressed. Due to the ramp-shaped oblique guide of the guide slots 28 thereby creates a rearwardly directed force which moves the support and bolt slide 15 against the force of the spring assembly 16 backwards, i. removed from the front bearing part 3. In this way, the handle 25 can be depressed so that the transverse rod 27 in turn engages in the recesses 30 and the support and locking slide 15 is again held in the release position of FIG. 3.

Now let the support plate assembly 4 with the foot or on the ski boot are pivoted sufficiently in the upward direction. In addition, turn the handle 26 may be briefly depressed with the ski pole. In this case, the spring assembly 16 pushes the support and locking slide 15 to a position in which the transverse bar 27 of FIG. 4 reaches the upper end of the slot slots 28 or in the embodiment of FIGS. 5 to 9 at the within the slot slots 28th trained undercut step 31 abuts. Thus, the support and locking slide 15 is prevented from further approaching the first bearing part 3. The ends of the slot slots 28 in FIG. 4 and the steps 31 within the slot slots 28 of FIGS. 5 to 9 are arranged so that the support and bolt slide 15 with its support pair 19 assumes a position below the end piece 8 of the support plate assembly 4, so that these always one of the column height corresponding minimum distance from the ski top has. This facilitates the ascent on slopes.

By depressing the handle 25 of the support and latch slide 15 can be pushed back into the above-described release position of FIG. 3 again.

In the embodiment of FIGS. 5 to 9 further there is the possibility of depressing the handle 26 with the ski pole. Thus, the transverse bar 27 is lifted over the step 31. If at the same time the support plate assembly 4 is pivoted upwards about the transverse axis 5, now pushes the spring assembly 16, the support and bolt slide 15 further forward until the cross bar 27 abuts the upper end of the guide slots 28 above the steps 31. In this position of the support and locking slide 15, the further support pair 22 cooperates with the end piece 8 of the support plate assembly 4, so that it is supported with its tail 8 at a relatively large distance from the top of the ski and also facilitates the climb on very steep slopes becomes.

The embodiment illustrated in FIGS. 10 to 14 in turn has a bearing part 14 to be mounted on it. This has edge strips 140 directed upwards on its longitudinal side edges, which are each provided with a groove-like undercut on their mutually facing side surfaces. Incidentally, on the edge strips bearing blocks 141 formed with bearing lugs 142, the purpose of which is explained below.

Between the edge strips 140, a base plate 143 can be inserted, wherein the longitudinal side edges of the base plate 143 of the undercuts of the edge strips 140 are C-shaped. The longitudinal side edges of the base plate 143 are formed in some areas as facing each other with their concave sides C-profiles 144. In addition, a lug-shaped abutment 145 is arranged or formed on the base plate 143 in the example of FIG. 10, the purpose of which will be explained below. The base plate 143 can be made of a metal sheet, wherein the tab-shaped abutment 145 can be generated by appropriate Austanzung and bending deformation.

The bearing part 14 is fastened together with the base plate 143 on the ski 1. This can be done, for example, by screwing, wherein the fastening screws pass through mutually aligned openings 146 on the bearing part 14 and on the base plate 143.

The C-profiles 144 of the base plate 143 are used for sliding guide a support and bolt slide 15, at the longitudinal edges of the C-profiles 144 matching guide rails 147 are formed.

As can be seen in particular from FIG. 11, the support and locking slide 15 has one at its underside open recess which serves to receive a helical compression spring 160, which is supported with its one end on the arranged on the base plate 143 abutment 145 skifest and is stretched with its other end against a corresponding support surface, which is arranged on the support and locking slide 15 and extends substantially in a vertical transverse plane of the support and bolt slide 15. Accordingly, the helical compression spring 160 seeks to push the support and lock slide 15 in Fig. 11 to the left.

At the left in Figs. 10 to 14 end of the support and locking slide 15 locking latches 17 and supports 19 are arranged, with which on the one hand a skifeste locking of the end piece 8 of the support plate assembly 4 in resting on the ski top layer and on the other hand, a support of the tail 8 in lifted from the ski top side position is possible, as will be described in more detail below.

At the right end in FIGS. 10 to 14 of the support and locking slide 15, a bearing block 150 is formed in the embodiment of FIGS. 10 to 14.

Between the bearing blocks 141 of the ski bearing part 14 and the bearing block 150 of the support and locking slide 15, a toggle lever arrangement 152 is arranged. This has a first toggle 153, which arranged by means of a bearing in the eyes 142 of the bearing blocks 141 of the ski bearing part 14 Axis skifest is pivotally mounted. The other knee lever 154 of the knee lever assembly 152 is pivotally mounted by means of an axis which is arranged on the bearing eye 151 of the bearing block 150 on the support and bolt slide 15. Moreover, the toggle lever 153 and 154 are hinged together to form a knee joint 155 hingedly by a corresponding axis or axle.

A handle 156 arranged on the knee lever 153 in the example shown can be depressed manually or by means of a ski pole in order to be able to bring the toggle lever arrangement 152 into the over-center position of FIG. If a further handle 157 arranged on the toggle lever 154 is pressed, the toggle lever arrangement 152 can be triggered from the abovementioned over-center position, so that the positions of the support and locking slide 15 shown in FIGS. 11, 13 and 14 are made possible.

When the toggle lever assembly 152 assumes the over-center position of FIG. 12, the support and latch slide 15 occupies a position far to the right or longitudinally displaced rearwardly of the ski bearing member 14 because the toggle assembly in this position has a large clearance between the pedestals 141 of the skifesten bearing part 14 and the bearing block 150 of the support and locking slide 15 forces. The Übertotpunktlage shown in Fig. 12 of the toggle lever assembly 152 is maintained by the in this state of the toggle lever assembly 152 highly compressed helical compression spring 160, the Stützund Slide latch 15 in Fig. 12 to the left and thus seeks to reduce the distance between the bearing blocks 141 and the bearing block 150.

12, the support and locking slide 15 assumes its release position in which the end piece 8 of the support plate arrangement 4 remains vertically movable and, accordingly, the support plate arrangement 4 about the transverse axis 5 (see in particular FIG. 1). remains swung open.

Now let the support plate assembly 4 be stepped down on the ski upper side, so that the end piece 8 occupies the position shown in Fig. 12. When now the handle 157 is depressed, the toggle assembly 152 leaves the Übertotpunktlage of FIG. 12. At the same time, the support and bolt slide 15 moves under the force of the spring 160 to the left, the locking lugs 15 engage in corresponding recesses on the end piece 8 and engage on the tail 8 formed steps, such that the tail 8 and thus the support plate assembly 4 are held in laid on the ski top layer. This condition is shown in FIG.

If the support plate assembly 4 is lifted with its tail first from the ski top, before the toggle assembly 152 is triggered by depressing the handle 147 from the Übertotpunktlage of Fig. 12, the support and locking slide 15 of the helical compression spring 160 in the Supported position of FIG. 14, in which the supports 19 of the support and locking slide 15 assume their position below the end piece 8, so that the end piece 8 and accordingly the support plate assembly 4 must always occupy a height of the support 19 corresponding minimum distance from the ski top ,

By depressing the handle 156, i. by depressing the knee joint 155 of the toggle lever arrangement 152, the support and locking slide 15 can be placed at any time from the positions shown in FIGS. 13 and 14 into the release position of FIG. 12.
