Karl Breuer, Mühlheim - Ruhr Ski security binding

The application relates to a ski safety binding with tensioner, in which an adjustable spring is arranged, with a adjustable pulling part that is located on the heel of the ski boot on the one hand and at the toe of the boot on two swiveling spring-locked ones On the other hand supports the jaws

The invention is characterized by individual new groups and their combinations, which in their entirety are completely new solutions which is the reason for the versatility, which is illustrated by a few examples.

The invention solves the problem of not having any devices preventing the boot from slipping off in front of the toe of the boot to have to build the binding very low and to ensure an extremely comfortable operation of the binding in terms of getting in and out of the Binding and adapting to the different driving conditions

namely, climbing, descending, cross-country skiing and, above all, loosening the binding in the event of overloads caused by the various driving conditions if the forces are too great and if you lose your state of equilibrium in the various driving states · Despite Advantageous innovations in the groups, the main advantage is due to the fact that the tension spring for clamping of the ski boot on the ski at the same time the latching on the toe cheeks is applied, which is exceptionally important Simplifications in the production an extremely convenient operation when getting in and out and releasing the securing means, this is also a very simple setting for the skier result from the skier and the sports shops «

A prominent innovation with particular advantages in terms of simple production and simple operation results from the fact that the tensioner behind the heel in a novel way is arranged where it remains completely free of icing. The latch on the toe cheek bracket is for each individual Toe cheeks specially arranged · This Raateinrichtung is Low-friction and particularly simple, since it can practically be produced by a complete cut, is very low and there is no way that snow can penetrate, so it is also free of ice.

The examples show optimal solutions as well as partial solutions, e.g. solutions for bindings that are used for cross-country ascents and downhill skiing are equally ideal there are still solutions that are not optimal solutions for cross-country skiing and solutions that are essentially are suitable for ascent and downhill skiing, in which the ski boot heel differs far less from the ski boot heel than in cross-country skiing Ski surface takes off · However, they all have one thing in common

Remarks that great emphasis is placed on moving on Leg fatigue through one's own strength through too rigid attachment to the ski surface or through application To avoid great spring work by the foot, paying particular attention to the rigid clamping across the ski surface Value was placed *

The fact that the tension spring also simultaneously fulfills the task of ! loadfeder takes over, there are completely new advantages. if E.g. the safety clamp triggers when the forces are too great, at the same time the side cheeks are practically free from locking, so that the ski boot or the skier's foot suddenly can move freely in any direction on the ski surface. The jaws can be swiveled back in after the Safety release of the tensioner or the locked jaws with the skier in an upright position by a spring or be carried out with the foot, since practically only a small hasty pressure is applied to the detent. Can continue through this combination made the setting of the toothed jaws on different ski boot widths in the simplest possible way be that several locking grooves are attached to the toe blocks, which allow a coarse adjustment, the fine adjustment is thereby ensures that the two toe cheeks are placed in a wedge shape and only the ski boot can be moved lengthways to rest the toe cheeks come. If the toe cheeks are triggered, the second locking grooves, for example, can be rolled over without any clamping forces possible because the tensioner pull has already been reduced and the locking force is also reduced when the first active locking groove is left has been.

There are known safety ski bindings in which individually pivotable jaws are used. But these are before the

909828/0559

The tip of the boot and are so high that if the skier stumbles forward through tree stumps, rock pinnacles, sand, earth, grass or other obstacles, the skier stumbles and the most serious falls occur, which in addition to leg injuries result in serious head injuries. however, only broken legs and dislocations are the result. As is well known, the skier likes to lie on his side in case of danger and is afraid of falling forwards, which is why all known ski bindings are provided with a safety tensioner, which, however, only provides this safety device by increasing the tension of the rope when forward falls have already been initiated, i.e. bent lower leg and raised heel can work · Due to unfavorable bastions, joints and multiple rope runs, however, the release force is very different, especially when it is iced up. Such safety jaws do not respond to sudden frontal overloads, but only to the safety tensioner, which may be provided, when a fall has already been initiated. Another similar binding builds too high under the boot sole, which has been shown to be particularly disadvantageous when swinging on skis. Often swivel heads are used in front of the boot tip, but they are completely ineffective in the case of frontal overloads and because they are particularly high, stumbling is easy. Since there is no lateral guide in these swivel heads, additional jaws for the lateral guide are also provided in a complex manner for cross-country skiing. In cross-country, in which the rear cable guides are posted, and the lateral rotation does not respond, to known Sicherheitebindungen common that remain set to the same Bastdruck in to erhöhendem Spannerzug by readjusting the toe shoes, if not more, in addition they are also readjusted. So screwdrivers or coins are necessary for readjustment. It

909828/0559

So basically two adjustments have to be made · In addition In all known safety bindings, the bast spring, because it is too small, is so progressive that the bast force causes the bast force on the first rest path strengthens itself at first and then weakens to the point of notching · It also happens that a ski is twisted by several degrees without the basting disengaging, while a side fall has already been initiated.

There are also known ski bindings in which the heel is tensioned, but these tensioning devices are like that mounted on the ski and designed in such a way that they almost do not allow the ski heel to stand out from the ski surface, which causes leg fatigue when running through its own strength. This binding is also complicated and expensive on the other hand. Even if getting in is very easy, the spring tension by means of a small lever must be used to get out be released with greater force or the clamping of the ski boot on the ski is too weak, so that the ski guide is deficient. A similar binding with the release of a wedge on the heel is extremely inadequate, as it is very insignificant depend on pressure changes rather than on wedge displacements. Other voltages are known at which the safety device opposite Lasjfin ski direction or too big Heel pull on the heel is carried out by a device on the heel, which is arranged in the hollow between the heel and the heel of the boot is, however, this device is heavy and must be held in the groove with one hand while the tensioner be stretched with the other hand well in front of the boot tip got to. In many cases, this is almost impossible for older people and non-sporty drivers. Also, this facility has the disadvantage that the rope opens when the safety link is inserted, falls into the snow, or against the other leg hits and the ski has to be lifted up

909828/0559

to close the safety link with greater force. It is necessary - in order to avoid injuries - that the securing link on the right ski to the right and on the left Ski to the left opens. So the skis cannot be mixed up. In order to close this safety link again, so is To keep the pre-tensioning of the safety spring low, i.e. a large amount of tensioning work must be carried out on the tensioner. That The same also applies to the other bindings for the basting, since the locking always remains constant after adjustment, it is necessary to lift the toe cheeks of the skis back into place and to take the latch · Otherwise, almost everyone has Known bindings have the disadvantage that the entry or tensioning of the binding must be carried out with two hands, which is unsportsmanlike Ski runner is extremely difficult.

The invention eliminates all of these disadvantages, in particular in one exemplary embodiment there is a basic setting the rest through the sports shop for a very sporty driver or a completely unsporting driver Change the load and the tension of the tensioner only with a large twist grip the driving conditions and the Adapted to terrain and snow conditions, perform. Even the difficult setting for cross-country skiing can be carried out with the intervention control. Likewise the binding can be tightened and opened with one hand. After the safety release has been activated, the ski needs Spanners not to be lifted, also not to change the oil load, but all controls can can be carried out in the most convenient and simple way with the twist grip by lifting or turning. With security solution of the tensioner, the tensioner falls backwards onto the ski and remains there. The jaw engagement can, as with not machined bond reduces the locking forces to a minimum value.

909828/0559

fall back into place with your foot without you need to lift the ski. If, for example, the terrain changes significantly and has to be climbed, you can go through simply turning the rotary handle, the tension and thus the load can be increased in a convenient and simple manner, around them by screwing back on the subsequent descent in the event of stubbornness again to be more sensitive. . ι actually In a simplified manner, clamping lever is no longer necessary in this device, as in the case of bekarrfcen designs.

In the binding according to the invention there is a very soft spring with many windings in a large twist grip built in to not prevent a fall, and the toe cheeks if the toe is overloaded increases the force until it is released without a ski having to run at an angle. Since the toe cheeks laterally of the ski boot are arranged at an angle, only a small tension force is required for good clamping. There will also be the No wear of the parts, the clamping work less.

Many falls occur because binding is difficult to set, even for workshops. Since the binding according to the invention is mounted on a thin sheet metal, cloning errors cannot occur and the driver himself can cope with the twist grip conditions in the simplest and most comfortable manner. The S _e itenbacken are readily adjustable in height, angle and width. The main part of the binding is made of simple, cheap stamped parts, it is also very light, so that only a small weight has to be carried *

With the safety binding according to the invention, which does not prevent any fall of any kind of exposure, a guaranteed safety release is provided

S09828 / 0559

has been achieved:

1. When turning the foot to the left around the heel,

2. To the right around the paragraph,

3. rotation of the foot to the left around the ball of the foot,

4. To the right around the ball cross-country run,

5. In the event of sudden braking of the ski in the direction of travel,

G. In the event of an impermissible shift of balance to the front,

7. If you hit the ski from backwards,

8. It is also possible to adjust the tension slightly and locking to achieve a release when bending the foot backwards *

In the case of the binding according to the invention, the heel lock also releases off for cross-country skiing, as a very soft tension spring is used. This safety release is on with the stiff tension springs known facilities are not possible, since the change in path with the various flexions of the ski boot in cross-country skiing is such Changes in force triggers that the safety binding either not triggers or triggers too early.

The various designs of the safety binding according to the invention are described with reference to the figures, all of which show the The purpose is to achieve a universal ski safety binding for sporty drivers and the numerous unsporting drivers, for all driving conditions and with the terrain and snow conditions mentioned β en, whereby the safety release takes place as promptly and precisely as possible and not only when the fall has already occurred is initiated or the ski has a dangerous incline.

1 1 * are the swivel jaw levers with toe jaws 2 2 *. The screws 3 fasten the jaws rotatably by means of a ring 5 with a conical head on the ski and at the same time the base plate 6. Fig. 4. The locking levers Y 7 * carry rotatable Cylindrical rollers 10 10 ', which have large sliding surfaces. The cylindrical rollers each engage in a notch in the pivot lever 1 1 * a. Find the locking levers and lever levers inside on ring 8 their stop. The pull of the rope 24 is over a bar 17, which is in length in square holes 30 of the pressure piece 15 is mounted displaceably by means of the hexagonal head, on a locking distribution bar 12 transferred to the two locking levers 7 7 * across adjustable Rastdruckeinatellhebel 13 13 * is transmitted. All these parts are stamped parts of a sheet metal thickness, which in one Complete cut can be made The jaws 2 2 * are adjustable in angle and height on the screw bolts 19 and are secured by hexagon nuts 20. The rope 24 is passed through the guides 28 and 29 for the ascent and descent, and only over the guide for the Laigauf Guided tour 28. The cable pull is generated by the tensioner, which is in the groove 10 between the boot heel and Boot heel is inserted by means of the roller 50 and is pivoted upwards by means of toggle action. In the tension bracket 26 is a transverse slot 25 in which the rollable axle is mounted and on which the two cable runs laterally over Clamping pieces 48 are articulated. A rotary handle 23 with outside

909828/0559

The thread is screwed into the tensioning bracket 26 in a longitudinally adjustable and rotatable manner. This has a collar 62 in which
the tension and detent spring 22 is supported. This is based
on one side on the threaded washer 30, which is about
a bolt 37 is also supported in an articulated manner on the axis 51. When the twist grip 23 is screwed in and out, the pressure of the tension spring and thus the tension on the rope can be adjusted to a greater or lesser extent. During cross-country skiing, the twist grip is unscrewed and the axle rises up in the slot 25 in order to ultimately generate an adjustable tension.
A stop screw 27 enables the spring to be pretensioned when the tensioner is not supported, so that the tensioning work is small
can be held. This stop screw is slotted,
so that the end 38 of the bolt 37 enables the tightening of the tensioner by marks. When the tensioner is inserted, the ascending strand of the rope 24 lies on the heel above the central axis of the roller 50, so that the tensioner remains inserted by toggle action. When the tensioner is inserted, apart from in the groove, it is supported by the roller 50 on the heel with very little pressure by the stop ring 52 at the point 53. By turning the handle, different inclinations of the tensioner can be achieved by the eccentric stop ring 52, for example also for cross-country skiing.

When setting the binding for ascent and descent, the heel of the boot moves approximately around the toe of the boot steeper arrow direction · The axis 51 can, however, only in the flat arrow direction rotate around guide 29. When the heel of the boot lifts off the ski surface, the spring 22 will shorten and become stronger tense. The Bolle 50 comes to rest over the ascending rope strand and the tensioner tilts backwards down to the surface of the ski, so that the axis 51 comes to rest at point 51 *. Included

909828/0559

There is a large gap between the tensioner and the heel of the boot, which allows you to step back into the binding. The roller 50 can then again be inserted into the groove 70 on the heel of the boot and the tensioner can be turned upwards so that the rope is tightened again and the ski boot is guided and held on the toe cheeks 2 2 * and the roller 50. The same process takes place when the binding is set for cross-country skiing. The figure shows a lever 25 having the same function as the slot 25. FIGS. 6 and 7 show further versions of tensioners which are based on the principle of detents. In Fig. 6, for example, 59 is a latch on a lever 58, which is mounted in a corner of the handle housing 23 and which is supported by a spring 22, which is supported on the handle housing via a spar * ar eccentric lever 63 on the housing 23 and the axis with Rolls against the inclined surfaces pushes away from the ski surface and thus tensions the rope 24. If the cable pull is too big, the axle 52 presses over the rollers against the springs in the direction of the cable, the nose pivots over the plate 61 aa ski heel backwards and that _; Handle housing slides towards the ski surface. This frees the ski boot. After resetting, the eccentric lever 63 allows a greater distance between the handle housing and the ski heel for easier entry into the ski binding.

FIG. 7 shows a device similar to FIG. 6, the spring 62 is installed in a bore in the ski heel and is supported on the one hand on a sheet metal lever 64 which is hinged above in a sheet 61 and on the other hand via an adjustable nut 30, the bolt 39 and its head in the sheet metal 61. In a nose 64 of the sheet metal lever the clamping lever 63 is supported, which acts in the manner of a toggle lever. In this lever is an axis 51 on which the ropes are suspended so that in the tensioned state the rope runs above the roller 50, which is supported in the nose 64.

909828/0559

If the tension in the rope is too great, the sheet metal lever moves to the left and the lever 63 tilts in addition. right and put the Ski boots free.

Fig. 8 shows a plate 61 which is attached to the ski heel, which has an inclined surface 65 at the top and a hanging loop 66 at the bottom. The handle housing 23 and its cover 58 represent two Lever represents, with the joint 69, in which also still animal tensioning lever 63 is hinged. The tensioning lever has a fixed arm 63 'on which one joint span 68 engages, the other of which Articulation point 51 * represents the suspension axis for the cable 24 and which can roll in the dact-shaped curved path; if If the lever is moved to the right, the axle 51 overtakes the top of the roof to the left, while the spring 22 is tensioned and the upper support roller 53 comes over the inclined path to the vertical surface of the sheet 61 and the tensioner becomes free, as the lower suspension from the eyelet 66 is also solves.

The same thing happens if the cable pull becomes too big while skiing. Depending on the design of the control surfaces 67 can in front of, on or behind the top of the roof see the imgsau solution take place.

The stop screw 27 is used to adjust the preload of the spring so that only part of the clamping work is applied needs to be. The screw 30 serves to reinforce the spring

Fig. 9 shows another embodiment of a whole advantageous ski binding with the individual advantageous elements of this invention, but with swivel jaws 11 ', which are designed as scissors, with the front parts of the scissors jaws 2 2 * and further jaws 2 2 * in the heel area wear, which result in an even better ski control, whereby the

909828/0559

rear part of the scissors is formed from spring leaves, so that the heel can be lifted off the ski when cross-country skiing.

This design is based on the principle of turntables for ski bindings same. The rear tensioning device could also be dispensed with and a tension spring for downhill skiing be arranged, which holds the heel on the ski binding, as it is attached to the ski surface on the one hand and on the other hand is attached to a sheet metal plate of the ski heel.

10 and 11 show the front part of a binding according to the invention without a tensioner, but the smallest construction and for the highest demands. The Ila device for the jaw lever protrudes only a little over the toe of the boot. It shows the characterizing features of Fig. 1, only i ± the pressure piece 15 has become a pulling piece, in that it is passed centrally through the Hastung and the jaw pivot lever 11 'and the bar 17 replaces the previous front deep-drawn hook, the bar 17 for different boot slopes in a similar manner as in Fig. 1 can be offset longitudinally. For locking adjustment, needles 13 are provided here, which can be placed in different grooves. This should deliberately not be made from the outside, but only after lifting the locking cover 16, because only a rough basic setting of sports shops should be made according to the skier and with the proposed new tensioner is in the simplest way on all other conditions by turning the rotary handle set quickly and easily. Two bast grooves are provided for each ^{jaw lever 1 I 1} , which allow a rough setting for the boot width, the best take over the oblique σ)

levers ensure a good stability of the boot on the toe lever levers and a better pressure distribution. The bars can also be fixedly arranged on the tension piece 15 and the ropes are hinged 48 to the bar 17, the rope length being able to be lengthened or shortened by screw-in pieces, as shown in FIG. 10 a shows a detent that does not exactly disengage in the case of an overload _{in the u tt set for the invention.} The s is only a wish of the ski instructor, since beginner skiers too often express the side notches when learning with large side pressure, which can be avoided by means of knobs next to the locking grooves 4, since a larger angle of rotation always has to be carried out first. However, such a stop endangers advanced or mediocre skiers.

12 to 13 show tensioners behind the heels, in which a point of support is provided by means of rollers 50 in the fillet 70 lies between the heel and boot heel and the other support point 52 of the support body 26 is in an eye 23 of the Bockes 26 *, which is attached to the ski surface. The twist grip clamps have the same basic structure as in Fig. 1 described. FIG. 12 is practically the same as FIG. 1, only that the bolt 51 is on the inclined surface 25 instead running on a slot. In Fig. 13 ii of the twist grip tensioner is even chosen so that it is with its lower support point either on a bracket 26 'in the eye 53 or else the eye or roller 53 come to rest on the heel of the boot can so that he rides completely on the heel as in Fig. 1. In Fig. 13 the upper support point is also lifted in the groove 70, the lower support point is the eye 51 of the bolt 37, which is in an eye 53 of the bracket 26 ', which is attached to the ski, is stored. The suspension of the pulling part, e.g. pulling rope, takes place on an eye 51 'of the support body 26. Inclined slots, inclined surfaces or levers 25 are not necessary with this version. The twist grip clamps according to Fig. 12 to 13 are naturally very deep, so that it

909823/0 5 59

It is possible, as shown in Fig. 13, to design the pulling part 15 as a bendable wire or wire rope, which is articulated on the one hand in the latching distribution lever 12 and runs centrally under the boot sole through the binding to behind the boot heel, in a sliding piece 29 with an eye , which can slide longitudinally in the deep-draw holder 29 or it is shown in FIG. 12 b on the bearing block 2G attached to the ski ^! a further bearing block is arranged, in the eye 29 ″ of which a lever 29 'is arranged, in which the wire or the wire rope 15 is articulated and also the rope run or adjustable rods 24, which are articulated in the eye 51 on the other hand.

This version avoids guiding the rope or wire (15), which could increase friction * In this version the side tension hooks at the front and back are no longer necessary come, i.e. the ski is unobstructed on its sides, and this is the simplest version of the universal ski binding.

As the individual groups of the complete ski binding are particularly advantageous , combinations with known parts of ski bindings can also be carried out. 14 shows the advantageous one Twist grip tensioner 23 in on the heel on two points riding form, which with its sides 24 with the deep-drawn eyes a known turntable are connected. As shown, known swivel jaws or swivel jaws can be used on the toe of the boot with a detent according to FIG. 10 of the invention and reinforced spring 19 with an adjusting screw (not shown) below Elimination of the pulling piece 15 can be arranged. The same applies to FIG. 15, in which the cable run 24 is attached to two deep-drawn hooks are articulated on the side of the ski. For cross-country skiing, the front deep-drawn hooks 28 could also be arranged here, with then the deep-drawn hook 29 only serve as a guide.

Fig. 16 shows a complete ski binding with a known pivoting tensioner 23, the when entering the paragraph Lever 50 * depresses and thus the support member 50, the fillet 70 presses. The now tensioned spring is supported by the holding piece 51, the rod, the wire or the wire rope 15, at the latching according to the invention on the latching distribution lever 12. Contrary to the known design, the tensioner is longitudinally

achieblich and guided and knows a guide and approximate Bracket 53 off.

FIG. 16 b shows a tensioner according to the invention on the heel with a jaw ratchet (not shown) according to the figure with a support roller 50 and a second support roller 52 on the support body 26, the latter being in the eye 53 of the bracket 26 * as in FIG. 12 b. and eratere is supported in the groove 70, while the spring 22 is supported on a longitudinally displaceable sliding piece 51, the rope 15 on the front catch and on the other hand via a tensioning lever 23 with eccentric or in the manner of a toggle lever and an angle lever 51 on the bracket 26 'on the STeIIe 51 "of the bracket 20 is supported. the block 26 has an S _c hrägschlitz 25 for receiving the roller 52. In large heel pull the spring 22 is more charged, the bell crank rotates aiii to the left, the supporting body 26 to the right, the slope 25 becomes steeper, the support body moves to the left and the contact point 51 ″ comes out of contact, the ski boot being pressed forward against the spring 22 and the abatement body with the ball 50 releases the heels. Before boarding, the tensioner is relaxed and the support body 26 is pushed to the right over the support point 51 ″ and the tensioner is re-tensioned.

17 shows the effect of the basting according to the invention shown, in comparison with known bastings · The locking ball or the locking cylinder moves out of the lock via the latching point B until it excites the latching force 0 vertically above the latching point B. I «Index 0 is the midpoint of the Latching body, τοη him from in the abscissa is the way of the RastkSrpers applied. The locking force P is plotted in percent on the ordinate. With constant bast spring force results a Rastdruckrerlauf after the solid curve a.

909828/0559

If, as according to the invention, the tension spring is used as an actuating spring, it has a very flat characteristic and this results in a bast pressure curve according to the dotted line b. However, if a conventional detent spring is used with a small number of turns and with a small diameter, as has been required since then, in order not to let the structural parts become too large before the binding, since otherwise an even greater hindrance would occur when the ski boot slips through, so results So a very stiff bast spring with the force curve according to the curve PR and according to the dash-dotted curve c, the latching pressure curve. However, if, as is customary in Hegel, the locking point R is below the point R ', then in the case of the locking spring described last there is a locking profile according to the dashed line d. It can be seen that halfway through the detent, the detent pressure in curve b has dropped to 40 % in curve d to 70 j> and that in curve d it has even risen to over 140%. This means that with a stiff detent spring, the ski has already twisted by a possibly inadmissible amount, at which rotation a fall is initiated without the detent even thinking of responding. In contrast, the detent speaks at a soft detent spring characterized in that one uses the greater · dimensioned clamping springs, since the detent counter force drops considerably at the specified force of $ 100 on at a low Rastweg.

For the sake of clarity, Fig. 13 shows the essentials Differences between the known ski bindings and ski bindings after they have been found in a schematic representation in the most important parts.

a) are the known versions. Pivotable safety jaws are shown, which have a detent 10 are fixed by the bast spring 49. The tension spring 22

909828/0559

BATHROOM 0W6WAL

is supported during tensioning by the toggle lever 23 via the tensioning body 26, which is attached to the ski, thereby tensioning the Cable 24, which is supported in the groove 70 of the ski boot. The detent is therefore completely independent.

In b) the basic elements of the invention are shown with known front tensioners. The jaws 2 and 2 ¹ on the pivot levers 1 'and 1 each have a Hast 10 or 10 *. When the toggle clamp 23 is tightened, the rope 24 is tightened and is supported on the heel of the shoe 31 in the groove 70. On the other hand, the spring 22 is tensioned and is supported on the movable clamping body, which is guided in a guide 17, and transfers the pressure via the pressure piece 15 to the load distribution lever 11, which is located on the notches 10 or 10 ' supports.
