The plate is fixed on the ski, and reinforced, in the manner of a conventional downhill ski binding by the further catch element in the front region of the ski binding and, in the locked state, is anchored at the front end and at the rear end, and at a number of locations therebetween, on parts of the ski or parts which have been fixed to the ski.

Description

Description SKIBINDING

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

In a ski binding of this type known from DE 26 60 145 C2, the suitable for touring ski plate is locked in its rear region by two laterally arranged locking elements against two brackets mounted on the ski. In order to release the plate for the tour position, these locking elements must be moved or stranded versilt.

An advantage of this arrangement of locking elements is that they are positioned within the binding region, ie between the front sole holder and the rear heel holder. Compared to the usual locking elements of touring plates, which are fixable behind the heel holder on the ski, results in a lower tension of the ski and a better power transmission when skiing. A disadvantage of the known embodiment, however, is that the plate must be made relatively stiff in order to identify sufficient strength in alpine skiing and to prevent the plate tilts especially when edges of the ski in the front area. This leads to a low tilting stiffness, which is necessary especially in alpine skiing.

To date, therefore, there are either special touring bindings, with specific characteristics for touring and adverse effects for the downhill, or there are alpine ski bindings that have the specific characteristics for alpine skiing but have no touring characteristics.

Recently, a new ski technique is increasingly used, which is known under the term "freeriding." In general, a wider ski than is traditionally used in order to drive off the slopes in the deep snow can still great value on a In order to get to places off the track, a touring ability is also desired, ie a way to allow by swiveling the ski boot Gehmöglicikeit, which usually requires a mitschwenkenden plate.

The desirable specific properties of such a ski binding are contrary to each other, so that there is still no satisfactory example in the prior art. It is therefore an object of the invention to provide a ski binding, which also offers unrestricted possibilities of downhill skiing in addition to good touring properties, without the Kippsteifigkeit the ski binding is impaired. Nevertheless, the ski binding should not be much heavier than a conventional ski binding, ie the mitschwenkende plate should either be flexible and / or can consist of a lightweight material.

According to the invention this object is achieved by the characterizing features of claim 1.

Advantageous embodiments of the invention are described in the subclaims.

The invention is thus based on the general idea that by the other locking element in the front region of the ski binding, esp. In the ball area of the ski boot, the plate is fixed and stiffened like a conventional alpine ski binding on the ski, i. The plate is anchored in the locked state at the front and at the rear end and in between several times on skifesten parts.

Protection is claimed not only for the features indicated below or illustrated in the drawing, but also for any combination of the specified or illustrated features in principle.

The invention will be explained in more detail with reference to the drawing. Show

Fig. 10 is a side view of this variant and

Fig. 11 is a vertical central longitudinal section of this variant.

The ski binding 1 shown in Fig. 1 has a front sole holder 2 and a heel holder 3, which hold a sole 4 of a conventional alpine ski boot or touring ski boot on a plate 5. The triggering function, the mechanics and adjustability of this front sole holder 2 and the heel holder 3 are basically known and will therefore not be described in detail here.

[0025]

The plate 5 is, as is known, pivotable about a front axis 6 upwards. In this case, this axis 6 is arranged below the front sole holder 2 transversely to the ski longitudinal direction on a ski bearing part 7. In order to achieve this pivoting of the plate 5, the rear end of the plate 5 must be freely movable upwards in the direction of the arrow "T", i.e. be positionable from a locked position to an unlocked position.

The ski binding 1 according to the invention therefore has in the embodiment shown in Fig. 1 front locking elements 8 and rear locking elements 9, which are arranged below the plate 5. The locking elements consist of a ski arranged on the lever mechanism 10, which has two coupling 11, 11 ', which are fixed at one end to a hub 12 and at the other of locking pins 13, 13'.

Preferably, the front locking element 8 is disposed below the ball area of the shoe sole and the rear locking element 9 below the heel area to allow a good power transmission to the ski. This arrangement has the further advantage that the locking elements are within the binding region or the region of the shoe sole and not outside, so that the natural ski deflection is practically not adversely affected.

On the plate 5 are now recesses 14, 14 'in bearing elements 15,

15 'is provided, in which engage the locking pins 13, 13' for locking the plate 5 on the ski. Instead of two recesses and locking pins, as shown in Fig. 1, of course, only one recess and in each case 1 locking pin can be provided. Also, the locking pin may have a different shape than shown in the embodiment.

To unlock the touring board 5, only the turntable 12 has to be rotated in the direction of rotation "A" (see Fig. 2), thereby coupling the coupling 11, 11 'fixed to the turntable 12, and thus rotating the turntable 12 Locking pins 13, 13 'are synchronously pushed out of the recesses 14, 14' After that, the locking elements 8 and 9 are unlocked and the plate 5 can be pivoted together with the shoe in the direction of arrow "T" for touring. To the plate 5 for the To lock down the alpine downhill course, it is necessary to proceed in the opposite order as described above. To operate the threshing wheel 12 easily, this has a non-illustrated handle, which can protrude laterally from the ski binding. Of course, other operating means are possible without departing from the scope of the invention.

In Figs. 3 and 4, another embodiment is shown, in which the ski binding 1 also front 8 and rear locking elements 9 has. In contrast to the exemplary embodiment described above, however, the entire plate 5 is displaced from the ski bearings 15, 15 'or their recesses 16, 16' in the longitudinal direction of the ski (see arrow "B"). The bolt webs 17, 17 'fastened below the plate are shifted from the locked position for the downhill run shown in FIG. 3 into the unlocked position for the touring ski run shown in FIG. 4, so that a pivoting of the plate upwards is also possible here ,

In order to move the locking bars 17, 17 'and thus also the plate 5 in the direction of arrow "B" and vice versa, a not-shown lever mechanism is provided which, as in the embodiment of FIG. 1 from a crank gear but also from each It is also possible in this embodiment also to provide only one locking element, for example in the central region of the plate.

It should be noted that the present invention is not limited to the described and illustrated embodiment, but that those skilled in the apparent modifications should be included.

Below is a particularly preferred with reference to FIGS. 5 to 11

Embodiment described in which as far as possible by the design principles illustrated with reference to FIGS. 3 and 4 use.

On the ski 20, two flexible base plates 21 and 22 (not shown in Fig. 5) are secured with screws 19 in the longitudinal direction one behind the other, which are designed so that they oppose flexural movements of the ski 20 no significant resistance. On these base plates 21 and 22 guide rails 21 'and 22' are formed, for example, as angle profiles with one formed on the associated base plate 21 and 22 vertical leg and a molded on the upper edge of the vertical leg horizontal leg, said horizontal legs in opposite directions can point outwards. On the guide rails of the front in the longitudinal direction of the base plate 21, the bearing part 7 is guided longitudinally displaceable. For this purpose has the bearing part 7 in substantially complementary to the guide rails shaped guide elements 23, which encompass the aforementioned horizontal leg of the guide rails and under, so that the bearing member 7 is held virtually free of play on the front base plate 21 by positive engagement with the guide rails in the transverse and vertical directions.

The bearing part 7 can be moved by means of a hand lever 24 between a front in the ski longitudinal direction and a rear end position in the ski longitudinal direction, when the hand lever is folded from its resting on the ski top layer in the other resting on the ski top layer. The hand lever 24 is pivotally mounted on the front base plate 21 or on the Skioberseite fixed bearing blocks about an axis parallel to Skiquerachse and forms together with a leaf spring 25, one end of which is fixedly connected to the bearing part 7 and the other end by means of a transverse axis 26th is hinged to the hand lever 24, a toggle-like unit. The leaf spring 25 is formed with a certain bias, such that the hinged to the hand lever 24 leaf spring end, the hand lever 24 in each case placed on the ski top position to stretch, with the knee lever assembly formed by the leaf spring 25 and the hand lever 24 in a Dead center or Übertotpunktlage is when the hand lever 24 is placed in one or the other direction on the ski top. Accordingly, the bearing member 7 is held immovably in the forward or rearward position in the ski longitudinal direction depending on the position taken by the hand lever 24, resting on the ski top end position.

On the bearing part 7, the base plate 5 is arranged pivotable about the transverse axis 27. In this case, the base plate 5 is held virtually immovable on the ski upper side when the bearing part 7 is displaced when placed on the ski upper side base plate 5 from its rear end in the ski longitudinal direction in the front longitudinal direction in the ski longitudinal direction.

In this forward displacement of the resting on the ski top side plate 5 act on the underside of the base plate 5 arranged guide elements 28 which are shaped similar to the guide elements 23 of the bearing part 7, latching with the horizontal webs of the guide rails 21 'on the front base plate 21 and similar guide rails 22 'on the base plate 22 together. If the base plate 5 is placed in the rear in the longitudinal direction of the bearing part 7 on the ski top, take the near the front end of the base plate 5 arranged guide elements 28 a position behind the longitudinal direction in the rear ends of the guide rails 21 'of the front base plate 21, while the further behind arranged guide elements 28 of the base plate 5 each occupy a position on corresponding recesses of the horizontal leg of the guide rails 22 'of the rear base plate 22. Now, if the bearing part 7 is moved forward in the ski longitudinal direction by the hand lever 24 is folded from its resting on the ski top layer position by about 180 ° in its other resting on the ski top layer, the guide elements 28 are each moved to a position, in which they encompass the horizontal webs of the guide rails 21 'and 22' of the base plates 21 and 22, so that the base plate 5 is held without play on the base plates 21 and 22 in the transverse and vertical direction, but remains displaceable in the longitudinal direction of the ski. This displacement in the longitudinal direction is important in flexing the ski. Since the base plate 5 has a more or less large vertical distance from the neutral bending zone of the ski, occur during flexing movements of the ski inevitably relative displacements in the longitudinal direction between the base plate 5 and the base plates 21 and 22, in particular the relative movements between the rear base plate 22 and the Stand plate 5 are relatively large, because the region of the rear base plate 22 has a relatively large distance from the bearing part 7, which is held virtually immovable by the leaf spring 25 and resting on the ski top hand lever 24. Thus, as soon as the bearing part 7 has been adjusted by means of the hand lever 24 in its rear in the ski longitudinal position, the base plate 5 takes its about the transverse axis 27 relative to the ski 20 upwardly pivotable, ie liftable from the ski upper side, as he is desired when touring. After lifting the base plate 5 from the ski upper side, a support bracket 29 from the non-use position shown in Fig. 6 by pivoting clockwise about 90 ° or 180 ° clockwise in a first or second latched position of use can be pivoted. In the first position of use, the heel-side end of the base plate 5 is supported in a predetermined by the length of the long leg 29 'of the support bracket 29 distance from the top of the rear base plate. This is particularly advantageous when slopes are to be overcome with great steepness when touring. In the second position of use, ie, when the support bracket 29 has been pivoted from the non-use position of FIG. 6 clockwise by 180 °, the heel end of the base plate opposite the top of the rear base plate 22 and the ski top in one by the length of the short Leg 29 '' of the support bracket 29 supported predetermined distance. This setting will chosen when walking tour comparatively flat slopes to be overcome.

Because when touring, i. at relatively pivotable to the ski 20 base plate 5, the bearing part 7 takes its rear in the ski longitudinal position is readily ensured that the center of gravity of the ski 20 in the longitudinal direction of the transverse axis 27 to which the base plate 5 pivots on the bearing part 7, and the ski tip always looking to sink downward when the skier raises his foot and thus the respective ski. The mentioned center of gravity of the ski is particularly advantageous in switchbacks or similar maneuvers.

Optionally, 22 recesses may be arranged on the upper side of the rear base plate into which the support bracket 29 is lowered when placed on the base plate 22. This gives the patch with the support bracket 29 on the base plate 22 base plate 5 increased stability in Skiquerrichtung.

The front sole holder assembly 2 is fastened together with the base plate 5 by the transverse axis 27 on the bearing part 7, wherein by a positive connection between the housing of the sole holder assembly 2 and the front end of the base plate 5 is a stationary relative to the base plate 5 support the housing of the front sole holder assembly 2 is guaranteed. When a ski boot is inserted into the ski binding 1, the front sole end of the ski boot is held in place by the sole holders 30 of the front sole holder assembly 2, the sole holders 30 laterally encompassing the front sole end. Ski boots for downhill skiing have standardized thicknesses, so that by adjusting the shape of the sole holder 30 easily a vertically backlash-free bracket can be guaranteed. The conditions are different with touring ski boots. There, the sole thicknesses can be very different compared to shoes for downhill skiing. Therefore, the front sole holder assembly 2 is combined with a vertically adjustable support assembly 31. This has a carriage 32 which is guided with lateral guide elements 33 on lateral guide webs 34 of the base plate 5 slidably. The guide webs 34 are arranged obliquely to the plane of the base plate 5, so that the carriage 32 is displaced in longitudinal direction in the direction of the guide webs 34 relative to the base plate 5 in the vertical direction. The position of the carriage 32 on the guide webs 34 is adjustable by means of a screw 35, the head of the bearing part 7 is axially and radially mounted, and the threaded portion is screwed into a nut 36 which is supported on the carriage 32 radially and axially with Taumelbeweglidkeit. On the upper side of the carriage 32 a slidable slide plate 37 is arranged, which is tensioned by a helical compression spring 38 in a central position. Preferably, the slide plate 37 is guided on the carriage 32 on a curved path, the center of which falls into the heel area of the ski boot. By appropriate selection of the materials can be readily ensured that the slide plate 37 is easily slidable on the carriage 32. Thus, the front end of the ski boot sole relative to the front sole holder assembly 2 is also supported with smooth mobility in the transverse direction, as is desirable for a good release function of the front sole holder assembly 2. This smooth sliding is guaranteed even if the bottom of the shoe sole should have a rutsciiiemmendes rubber profile.

The combined according to FIG. 5 with a Skibremsanordnung heel holder assembly 3 is slidably mounted on the base plate 5 in the longitudinal direction. For this purpose, 5 lateral guide webs 39 are arranged on the base plate, which cooperate positively with guide elements 40, i. the heel holder assembly 3 is held without play on the guide webs 39 in the vertical and sideways direction. The holder of the heel holder assembly 3 in the longitudinal direction of the base plate 5 by means of an adjusting screw 41 which is rotatably mounted within a housing part of the heel holder assembly 3 and is tensioned by a starting spring 42 against a housing-fixed stop 43. The set screw 41 has a helical male threaded portion, the threaded ridge engages in transverse slots of a toothed belt 44 which is arranged immovably on the top of the base plate 5 below the sliding in the guide webs 39 housing the heel holder assembly 3. By turning adjustment of the adjusting screw 41, the adjusting screw 41 is moved together with the heel holder assembly 3 on the toothed belt 44 and thus in the longitudinal direction of the base plate 5. Accordingly, the heel holder assembly 3 can be positioned in adaptation to the respective length of the ski boot sole. In this case, the heel holder assembly 3 relative to the adjusting screw 41 against the clamping force of the helical compression spring formed start-up spring 42 slidably so that the ski boot sole can be clamped clearance in the sole longitudinal direction, such that the starting spring 42 the heel-side sole holder 45 in a basically known manner resiliently in contact with the rear Sole end stops.

In particular, Figs. 7 and 8 on the one hand and Figs. 9 and 10 on the other can be removed, the hand lever 24 may be arranged in Skilängsriditung in front of or behind the bearing part 7. When arranged behind the bearing part 7, a corresponding recess 46 must be present in the base plate 5 in order to be able to accommodate the hand lever 24 on the ski upper side or on the upper side of the front base plate 21 in a siding-adjustable manner.
