Description

The The invention relates to a ski binding, in particular touring, telemark or cross-country binding for fixing a shaft and a Sole comprehensive ski boot, according to the preamble of the Claim 1.

A Such ski binding is from the date of the applicant WO 03/101555 A1. This known construction is characterized characterized in that front holding element, for example, in the manner of a toe may be formed, relative to the front and rear retaining element comprehensive unit around a transverse to the sole longitudinal direction pivotable in approximately parallel to the sole tread axis is stored. The front retaining element is thus formed quasi "dynamic" The consequence of this is that the front holding element when lifting the heel hardly resistance guaranteed. This is achieved in that the front retaining element of Movement of the front sole end relative to the rear retaining element or the two holding elements comprehensive assembly can follow. The front sole end is therefore not necessarily by the front Holding element or toe iron on the top of the binding or on the ski deck depressed such that the front sole end always extends parallel to the ski deck, and Although independent from lifting the heel.

Of the present invention is based on the object, the well-known To further improve construction in terms of the aforementioned "dynamics", and in particular also measures with which the binding is easily brought from a "cross-country position" to a "telemark position" and vice versa be in the first position of the shoe heel in should be able to be freely lifted freely while in the latter position lifting the heel through the elasticity the sole of the shoe on the one hand and the counteraction of the one between the front and rear retaining element effective clamping device on the other limited should be. The heel is only slightly liftable in the "telemark position", in such a way that the Skiers can exercise the so-called "telemark style".

These The object is achieved by the characterizing features of claim 1 solved, wherein advantageous developments and structural details of the invention in the subclaims are described.

One An essential aspect of the present invention is therefore that that the the front sole end associated support means on which the Front sole end rests, not an integral part of the Front and rear retaining element comprehensive unit is, but pivotable relative to this about a horizontal transverse axis and if necessary, namely for the so-called "telemark position" can be locked.

Thereby, that the The sole support end associated with the front sole end pivotally mounted is, is the support the front sole end in "cross-country position" of the binding dynamic, in particular, if also the aforementioned "toe iron" or front retaining element about a horizontal transverse axis, in particular the same horizontal Transverse axis is mounted pivotably. The mentioned "dynamics" is further promoted by the fact that the aforementioned sole support relative to the front and rear retaining element comprehensive or arranged between these two holding elements assembly or Connecting part is pivotable, so that an adaptation to the curvature of the Shoe front sole takes place when lifting the heel. The mentioned unit and sole support device comply with the curvature the front sole of the shoe when lifting the heel. If then also the front holding element or toe iron still independent of the aforementioned components pivotable about a horizontal transverse axis is the front end of the shoe when lifting the heel essentially constraint free held.

Preferably comprises the front sole end associated support means a the front Sole end associated support plate or bar.

In in a known manner, the front and the rear retaining element comprehensive or arranged between these two holding elements assembly in the form of a strip, hollow, in particular pipe, U or the like. Profiles be formed. In particular, the aforementioned unit alternatively designed rigid or flexible in the vertical plane be. In the latter embodiment will be an even better adaptation of the support of the front sole to the bulge achieved when lifting the heel, especially if the front sole of the shoe is relatively soft. The cross-country skier then receives the feeling that he is over the Snow not only glides, but at the same time "goes." The support of the front sole conveys the cross-country skier the feeling, that he rolls on the ground.

The sole support device associated locking or locking device is in the on Proverbs 4 and 6 described in more detail.

constructive simple and yet functional is the execution according to claim 6, after which the sole support device and the assembly comprising the front and rear retaining members are mounted pivotably about the same pivot axis, wherein they Naturally according to the basic idea of the invention relative to each other around this Axis are pivotable.

• – vorderer Haltebügel
• – Sohlenstützeinrichtung
• – vorderes und hinteres Halteelement umfassende Baueinheit

nur eine einzige horizontale Querachse als Schwenkachse vorliegt. Diese Konstruktion ist funktionsgerecht und einfach, da sie mit wenigen Bauelementen auskommt.The front retaining element is preferably a bracket that overlaps the front sole end. In this respect, it is a known construction, as also described and illustrated in WO 03/101555 A1, Preferably, this bracket is also that of the sole support device and / or the aforementioned Assembly unit associated pivot axis pivoted, so that for the three elements

• - Front bracket
• - Sole support device
• - Front and rear retaining element comprehensive unit

only a single horizontal transverse axis is present as a pivot axis. This construction is functional and simple, since it requires only a few components.

Basically However, it is also conceivable for this three components each to provide a separate pivot axis, or assign only two of these three components a common pivot axis. The simplest embodiment however, the former is with only a single common one Pivot axis.

For securitiy purposes of the skier, especially in descents in "telemark position" of binding it is particularly advantageous if the front and / or rear retaining element a lateral swinging or disengaging the shoe from the binding allowed. This measure should also be independent from the mentioned Main aspect of the present invention can be regarded as an invention. The latter safety measures should therefore also for bindings apply, which have only the features of the preamble of claim 1. A particularly preferred embodiment is characterized in that the rear holding element two each pivotable about an upright axis mounted, the sole heel over and over brackets, in particular in plan view about L-shaped headband comprises each against the action of an elastic element, in particular Torsion spring element, upon application of a predetermined torque on the shoe to the outside are pivotable.

alternative it is also conceivable that the rear retaining element as a whole pivotable about an upright axis is to a lateral disengagement of the shoe to allow around the front retaining element, as soon as a predetermined lateral torque acts on the shoe.

noteworthy is still the embodiment according to claim 11, after which the clamping device on the one hand and the locking bar for the Sole support device on the other hand associated actuating lever each opposite in the clamping or locking position pivoted are. As a result, a particularly compact design is obtained. In the aforementioned positions of the two operating levers these are virtually one above the other. To a collision of the two operating levers to avoid, one of the two is preferably designed as a U-bracket, so that in the space between the two legs of the U-bracket of the other operating levers can dive.

Finally, be especially mentioned, that the formed according to the invention Binding preferably on a carriage, in particular U-profile-like Sled is mounted on the ski, especially on one longitudinally displaceable on the ski-mounted guide plate stored and can be fixed in discrete places. This is one easy mounting of the binding when purchasing an associated ski either by the seller or the user possible. The same applies to dismantling. It must be at the assembly no longer in the ski body by fastening screws or the like intervened. The guide or mounting plate can be extremely thin-walled and thus be made highly flexible, so that the bend of the ski or the so-called flex not hindered by the mounting plate is. Preferably, the management or mounting plate made of an extremely thin-walled plastic profile, its modulus of elasticity less than or equal to the modulus of elasticity of the ski deck corresponds. Preferably is the mounting and guide plate on the ski deck area glued over a large area. The thickness of the mounting or guide plate is about 0.5 mm to a maximum of 1.5 mm, preferably about 1.0 mm.

below become preferred embodiments the binding according to the invention with the attached Drawing closer described. Show it:

1 an embodiment of an inventively designed ski binding in side view;

9 the embodiment according to 8th showing a lateral release of the shoe or the shoe sole associated with the sole under the influence of a predetermined lateral torque, so that the shoe is released to the side.

The in the 1 to 7 illustrated ski binding can be used on the one hand as touring or cross-country binding and on the other hand as a telemark binding. It is with the reference number 10 characterized. Of course, this ski binding is used to define a boot and a sole ski boot. This ski boot is not shown in detail. Only in the 8th and 9 is the contour of a front sole 11 a ski boot shown between a front retaining element 12 and a rear retaining element 13 is clamped. The corresponding clamping effect is indicated by the arrow 14 indicated. Incidentally, the embodiment according to the 8th and 9 described below.

Back to the embodiment according to the 1 to 7 It should be noted that these, too, a front holding element 12 and rear retaining element 13 between which, for example, the front sole of a ski boot can be clamped, against the action of two in each case within a spring housing 15 arranged compression springs, with the rear retaining element 13 on the one hand and a tensioning cable 16 on the other hand, the tension cable 16 around a front deflecting block 17 is led around. This diverter block 17 is inside the binding housing 18 slidably mounted in the binding or ski longitudinal direction, wherein the displacement of the Umlenkblocks 17 by a pivotally mounted about a horizontal transverse axis actuating lever 19 he follows. Specifically, between the operating lever 19 and the diverter block 17 another actuation cam 20 arranged. This actuating cam 20 is on the operating lever 19 around a horizontal transverse axis 21 pivoted. In the closed position of the binding according to 3 lies this transverse axis 21 below the connecting line between the pivot axis 22 of the operating lever 19 and the point of attack 23 the actuating cam 20 at the deflection block 17 , In this "over-center position" is the operating lever 19 secured in closed position. In open position of the operating lever 19 according to 5a lies the transverse axis 21 significantly above the connecting line between the pivot axis 22 and the point of attack 23 ,

By means of the operating lever 19 is over the guy cable 16 and against the effect of the mentioned compression springs within the spring housing 15 the rear retaining element 13 , which is formed in the manner of a one in the rear region of the front sole formed, rearward facing sole projection and cross-holding bracket, in the direction forward according to arrow 24 in 3 movable, this movement also against the action of another spring element 25 within a arranged between the front and rear retaining element assembly 26 takes place as a comparison between 3 respectively. 5b on the one hand with 5a on the other hand shows very clearly.

5a shows the bond 10 in the open position, ie with the rear retaining element 13 in the direction of the arrow 27 moved backwards, due to the compression spring 25 within the unit 26 , which is arranged between the front and rear retaining element and these two holding elements also includes. Of course, the movement of the rear retaining element 13 backwards in the direction of the arrow 27 only by movement of the operating lever 19 in open position accordingly 5a permits; because this makes it possible that the Umlenkblock 17 including tension cable 16 due to the in the spring housings 15 move arranged spring elements backwards.

Moreover, the serve in the spring housings 15 arranged spring elements as a kind of "flexor", ie support the return movement of the assembly 26 with the heel raised to the ski. In addition, compensate in the spring housings 15 arranged spring elements a through bending of the unit 26 if this is elastic in bending.

The already mentioned several times unit 26 is plate-shaped, namely for supporting the front sole of a ski boot with the exception of the front sole end of the same. This is supported separately by a relative to the unit 26 pivotally mounted sole support device 28 , The associated pivot axis extends horizontally and transversely to the binding or ski longitudinal direction. It is with the reference number 29 characterized. Around this pivot axis 29 is also the unit 26 pivotally mounted, preferably relative to the front sole end associated support means 28 , Furthermore, the front retaining element is preferably also around this pivot axis 12 pivotally mounted, which in a conventional manner as a front sole end cross-bracket or in the manner of a "toe" is formed.

Like a comparison between the 3 on the one hand and the 5a and 5b on the other hand, is the sole support associated with the front sole end 28 , which is web-like in the illustrated embodiment, locked by a separate locking element if necessary such that a pivoting about the pivot axis 29 is blocked (see 3 ). For this purpose, the front end of the sole support device 28 a locking bar 30 assigned, the lever by an actuating 31 in a position below the front end of the sole support device 28 is displaceable, until it is in contact with the underside of the front end of the support device 28 arrives. With raised operating lever 31 according to the 5a and 5b is the sole support associated with the front sole end 28 unlocked so that they are around the axis 29 can swing. So is the unit 26 for pivoting about the axis 29 Approved. In this unlocked position of the locking bolt 30 the binding is in so-called "cross-country position" while 3 the binding in so-called "telemark position" shows.

The operating lever 31 includes a cam 32 which is in a complementary recess 33 of the locking bolt 30 engages, so that by pivoting the actuating lever 31 about a horizontal transverse axis, in this case pivot axis 22 , a corresponding shift of the locking bolt 30 from his release order accordingly 5a . 5b in the blocking position accordingly 3 and vice versa. The above description and the representation in the 3 . 5a and 5b can be seen that the two operating lever 19 and 31 a common pivot axis, namely the pivot axis 22 have.

• – Baueinheit 26
• – Sohlenstützeinrichtung 28
• – vorderes Halteelement 12

eine gemeinsame Schwenkachse, nämlich die Schwenkachse 29 aufweisen. Diese Schwenkachsen-Konstruktion ist besonders einfach, da sie sich durch eine minimale Anzahl von Bauteilen auszeichnet.Furthermore, it can be seen from the above figures that the components

• - assembly 26
• - Sole support device 28
• - Front holding element 12

a common pivot axis, namely the pivot axis 29 exhibit. This pivot axis construction is particularly simple because it is characterized by a minimum number of components.

It should be mentioned again at this point that the sole support means is assigned only to the front sole end. Accordingly, the front sole end is between the front holding member 12 on the one hand and the aforementioned sole support device 28 on the other hand fitted, ie is held between these two elements or supported upwards and downwards. The lateral support of the front sole end also takes place through the front retaining element 12 , which is designed in the manner of a toe-iron (see also 2 ).

It is also conceivable that the front retaining element 12 as well as the sole support device 28 each in common, that is not independent of each other, about the pivot axis 29 are pivotally mounted. Alternatively, it is also conceivable that these two construction elements are additionally pivotable relative to each other. In any case, a relative pivotability between unit 26 on the one hand and front retaining element 12 as well as sole support device 28 on the other hand essential.

It was at this point also on 4 pointed. This shows the bond in longitudinal section 10 in closed position and raised heel. The sole support associated with the front sole end 28 is unlocked and thus around the pivot axis 29 as pivotable as the front retaining element 12 and the front retaining element 12 and rear retaining element 13 comprehensive unit 26 ,

The 4 leaves as well as the 1 very well realize that the bond described 10 on a sledge 34 with two side cheeks 35 is mounted. These two side cheeks 35 lie within corresponding, downwardly extending side cheeks 36 the building unit 26 (please refer 1 ). This ensures optimum lateral stability of the unit 26 relative to the sled 34 and thus get connected to the ski.

In 6 is the sled 34 shown separately again in cross section. The sled 34 is So formed as a kind of U-profile. Otherwise, the sled is 34 on a mounted on the ski not shown here mounting and guide plate 37 mounted longitudinally displaceable and in discrete locations 38 fixable. These discreet spots 38 are arranged by longitudinally spaced holes in the mounting and guide plate 37 Defined in which a fixing pin 39 engages (see 5a and 5b ).

The two operating levers 19 . 31 can each be rectified - as in the illustrated embodiment - or opposite pivoting in clamping or locking position. They are otherwise designed so that they do not collide with each other. For this purpose, both operating levers are designed as U-bolts, wherein in the free area between the two legs during movement of the actuating lever 19 . 31 in closing or locking position, the actuating cam 20 can dip, just like the 2 . 3 and 4 reveal.

Hereinafter, the embodiment according to the 8th and 9 pointed. This embodiment differs from the above-described embodiment only in that the rear retaining element 13 two each about an upright axis 40 pivotally mounted, a back protruding sole projection 41 encompassing and overarching bracket, namely in plan view about L-shaped headband 42 comprises, in each case against the action of an elastic element, in particular Tor sion spring element, upon application of a predetermined lateral torque "M" on the shoe are pivoted outwardly (see lower headband 42 in 9 ).

At the same time, the rear retaining element 13 then in the direction of the arrow 43 in 9 moved backwards, against the action of the aforementioned spring elements. The front sole 11 including the associated shoe can therefore escape laterally and turns almost to the front retaining element 12 (please refer 9 ). In this way, a high level of security for the user of the described binding is obtained, in particular also against complicated torsional fractures.

All Features disclosed in the application documents are considered to be essential to the invention as far as they are individually or in combination with respect to State of the art are new.
