Description

Ski safety binding The application relates to a ski leash binding with tensioner, in which an adjustable spring is arranged, with an adjustable pulling part in which an attachable pulling rope is engaged, which is supported on the heel of the ski boot on the one hand and on the tip of the boot on two swiveling, spring-locked jaws on the other , according to patent application B 66346 1 c / 77 b.

The invention represents an expansion of the solution to the problem in the main application, namely not to have any angle in front of the tip of the boot that would prevent the boot from slipping, to build the device very poorly and to ensure extremely convenient operation of the binding. visible of getting in and out of the / BLndung and of adapting to the different driving conditions, namely climbing, descending, cross-country skiing and, above all, of loosening the binding in the case of overloads caused by the different driving conditions and when losing the state of equilibrium in the different driving conditions.

In the main application, devices were described which allow elne low detent in front of the toes, so that when the ski boots slide away, both sides and forwards Inhibitions arise, but the tensioner was still attached in front of the locking device at a greater height than this, which on the one hand acted on the locking device and on the other hand was supported on the heel of the boot via the rope. In the case of prontal impacts through driveway on tree stumps, rocks, scree us1 # t. the two jaws of the binding can open and the spunner remains unopened, but lying at a greater height - #au, which is still a greater obstacle. In the event of a loss of balance due to bending forward and pulling the heel a lot, a safety tensioner was even larger, the latching needed lying down, which in the unfolded state represents an even bigger obstacle.

In contrast, the invention provides an extension of the previous application for Easier operation and simplification of the tensioner on the heel 2tensioning on the rope attached in front, so that actually in front of the boot there is no obstacle to sliding over Facilities are more available.

There are also known ski bindings where the tensions are provided on the heel, but these tensioning devices are mounted on the ski, are very complex and can be used with such. Bindings a cross-country skiing are not carried out. Further ski bindings are known in which the safety device is supported against overload or excessive heel pull on the heel in the flute between the heel and heel of the boot and on the rope, but the athlete is still in an obstructive manner in front of the toe of the boot. The operation It's not easy, because this heavy safety element is loose 21 vi cle 7 ## e rs Ver Rope with one fland rg # haffiten and with the other hand (#espannt must become. In addition, this device has the disadvantage that the rope opens when the safety link is inserted, snow falls into the snow, or hits the other leg and the ski has to be lifted to close the safety link with greater force. It is therefore necessary - to avoid injuries - that the locking member opens to the right on the right ski and to the left on the left ski, so the skis cannot be interchanged. In order to close this securing member again, the preload of the safety spring must be kept small, ie a large amount of tensioning work must be carried out on the tensioner. The sliding also applies to the other bindings for the detent, since the detent remains constant after adjustment Inu%, r must be lifted up for the re-engagement of the toe of the ski and the detent must be taken. All known bindings also have the disadvantage that the change in detent makes it difficult to change the tensioner, or that tools are even required.

The invention eliminates all of these disadvantages , in particular in one embodiment, after a basic setting of the detent from the outside, e.g. for a very sporty driver or a completely unsputting driver, changing the detent and the tension of the tensioner with a large twist grip, the driving conditions and the terrain and adapted to the snow conditions. Even the difficult setting for cross-country skiing must be carried out with the intervention condition. The binding can also be tightened and opened with one hand. The ski does not need to be lifted up after the safety release of the tensioner has been activated, nor does it need to change the detent, but all BedlaguM operations can be carried out in the most convenient and easy way with the handle by lifting or turning it. When the safety release of the tensioner, the tensioner falls backwards onto the ski and remains there. Since the locking forces drop to a minimum value when the binding is not tensioned, the jaw engagement can be engaged again with the foot without having to take up the ski. If, for example, the terrain changes a lot and climbs are made can, by simply turning the engagement, the tension and so that the detent can be reinforced in a convenient and simple way, so that it can be adjusted more sensitively by screwing back on the subsequent descent, if there is a risk of falling. In a simplified manner, an individual tensioner is no longer necessary with this device, as in known designs. The locking springs of the known bindings are very stiff since there is little space and few spring coils can be used. This leads to the fact that with a slight detent setting for triggering the detent preload almost assumes the value 0 and the skis first have to evade a larger angle until the detent force increases from practically = 0 to its maximum and then decreases and with it the detent notches.

In the case of the binding according to the invention, a very soft spring with many turns in a large grip is not required in the event of a fall which, when the toe cheeks are overloaded, increases the force to the point of notching, without a ski having to run diagonally. Because the toe cheeks on the side of the ski boot qi41em Elli - are arranged obliquely, is to a kgnzen (: opension only one small clamping force required. There is also less wear and tear on the parts, and the clamping work is less.

In some known bindings, swivel jaws on the tip of the boot and swivel jaws on the side of the toes are required in a complex manner. Many falls occur because of the cessation of a bond irfv? ' -i LL: #f - # c4.a & tn j ## z, Is too heavy even for workshops. Since d! EN1-nG # g on ' is mounted on a thin sheet metal, assembly errors can hardly occur and the driver himself can cope with the twist grip conditions in the simplest and most comfortable way. The side jaws are easily adjustable in height and angle. The main part of the binding is made of simple, cheap stamped parts, it is also very light, so that only a small weight can be carried.

The inventive security bond that does not fall any direction handicapped, a guaranteed safety release has been achieved '* for downhill skiing, on rotation each foot first to the left, the second to the right. with ver different adjustment forces, when-flexing around the heels, joxie -bee-at> Pahpteltmf. 3. when turning to the left, 4. when turning to the right around the ball of the foot as in cross-country skiing. 5. in the event of sudden braking of the ski in the direction of travel, 6. in the event of an impermissible shift of balance forwards, 7. in the event of an impact on the ski from backwards, 8. it is certainly possible, with a slight adjustment of the tension and detent, a release when the To reach backwards on foot.

The safety release of the tensioner on the heel becomes practical the latching of the side jaws is free, so that this also opens so that there is no obstacle to the To form fall.

In the case of the binding according to the invention, the heel lock is also released during cross-country skiing - if desired - since a very soft tension spring is used. This is not possible with the stiff tension springs on known devices, because the path changes with the various flexions of the ski boots Vtra LA c4, he LA Pf 9 ir V) during cross-country skiing, so that the binding either not at all or triggering too much spray.

There are still further embodiments of the sleher-style weave according to the invention described on the basis of the figures, all of which have the purpose of a universal Skl safety binding to reach for sporty drivers and the numerous unsportsmanlike drivers, for all driving conditions in the terrain and snow conditions mentioned, where possible the safety release should take place in good time and dle-apst not only when the fall has already occurred.

Figure 1 shows the universal ski safety binding in the simplest version in the basic view, Figure 2 in the side view.

The figure is a partial section of the attachment of the rope runs with the bridge to change the rope distance.

Figure 4 shows the articulated mounting of the pivot lever, in section.

Figures 1 and 2 represents a complete ski safety binding in the interaction of all parts with a tensioner, whose spring force also acts on the detent and enables the Hal sion and Sicherheitaauslösung of the toe cheeks and the heel of the ski boot. The numbering of the parts is as in the main application, 1 lt are the swivel jaw levers with toe jaws 2, 21.

The screws 3 fastening the pivoting jaws rotatable by means of a ring 5 with a conical head on the ski and at the same time the base plate 6 0 have the locking lever 7, 71 carry rotatable cylindrical rollers 10, 101, the large sliding surfaces. The cylindrical rollers each engage in a locking notch in the pivot levers 1, 12 . The locking levers and pivoting levers find their stop on the inside on the ring 8. The cable pull of the cable 24 is over a bar IT, which is mounted displaceably along its length in square holes 30 of the pressure piece 15 by means of the hexagonal head 14, onto a distribution bar 12 transferred, the a: uf both latches 7, 71 across transversely (l # 13., 1 adjustable Rastdruckeinstellhebe i is transferred. All these Parts are stamped parts of a sheet metal thickness that can be produced in one complete cut. The jaws 2, 21 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 holes 28 and 29 for ascent and descent, and only passed over the guide 28 for cross-country skiing. The cable pull is generated by the tensioner, which is inserted in the hollow groove between the boot heel and boot heel by means of the roller 50 and is pivoted upwards by means of a toggle lever effect. In the tensioning bracket 26 there is a transverse seat 25 in which the rotatable axle 25 is mounted and to which the two cable runs are articulated on the side via clamping pieces 58. A rotary grill 23 with external thread is to SpannerbUgel 26 along ADJUSTABLE r and dre, eingesehraubt hbar. This has a collar 62 'in' which the tensioning and detent spring 22 is supported. This is supported on the other side on the threaded washer 30 , which is also supported on the axle 51 via a bolt 37 . When the rotary handle 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 removed and the axle rises up in the slot 25 in order to ultimately generate an adjustable tension. A stop screw 27 ′ enables the spring 22 to be pretensioned at -not inserted Tensioner, so that the clamping work can be kept small. This stop tube is slotted so that the end 38 of the bolt 37 enables the tightening of the tensioner by means of 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 9, it is supported in the groove 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 around the tip of the boot in the direction of the arrow. However, the axis 51 can only rotate about the guide 29 in the flat arrow direction. When the pin heel lifts off the ski surface, the spring 22 will be shortened and tightened. In this case, the roller 50 comes to rest over the resulting cable run 50 and the tensioner tilts backwards down to the surface of the ski, so that the axis 51 comes to rest at point 511. This creates a large gap between the 3 tensioner and the boot heel, which allows you to step back into the binding. Then again, the roller 50 can be inserted into the groove on the boot heel 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, 21 and the roller 50. The same process takes place when the binding is set for cross-country skiing.

Figures 7 and 8 show further versions of tensioners based on the principle of detents. In Figure 7, 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 tensionable eccentric lever 63 on the housing 23 and the axis with rollers against the Pushes inclined surfaces away from the ski surface and thus tensions the rope A. If the cable pull becomes too large, the axle 52 presses against the springs in the direction of the cable via the rollers, the nose pivots backwards over the sheet metal 61 on the Sklabsatz and the handle housing slides towards the ski surface. This frees the ski boot. The eccentric lifting device 63 allows a greater distance between the handle housing and the ski heel after it has been reset, so that it is easier to get into the ski binding. FIG. 8 shows a device similar to FIG. 7, the spring 62 is installed in a bore in the ski heel and is supported on the one hand on a sheet metal lifting lever 64 which is hinged above in a sheet metal 61 and on the other hand via an adjustable nut 30, the bolt 37 and its head in the sheet metal 61. The clamping lever 63 , which acts like a toggle lever, is supported in a nose 64 of the sheet metal lever 58. In this lever there is an axis 51 on which the ropes 24 are suspended so that in the tensioned state the rope runs above the roller 50 which is supported in the nose 64. If the tension in the rope is too great, the sheet metal lever 58 moves to the left and the lever 63 tilts to the right and exposes the ski boot.

FIG. 9 shows a sheet metal 61 which is fastened to the ski heel, which has an inclined surface 65 at the top and a mounting eyelet 66 at the bottom.

The handle housing 23 and its cover 58 represent two levers with the joint 69, in which the clamping lever 63 is also articulated. The tensioning lever has a swept arm 631, on which a joint span 68 engages, the other pivot point 51 'of which represents the suspension axis for the cable 24 and which can roll in the roof-shaped curved path 67. When the lever is moved to the right, the axis 51 rolls Over the roof to the left, while the spring 22 is tensioned and the upper support roller 55 comes over the inclined track 65 to the vertical surface of the sheet 61 and the tensioner is free, since the lower suspension from the eyelet 66 is also released. The same thing happens if the cable pull becomes too big while skiing. Depending on the design of the Sbeuer surfaces 67 , the fuse can be triggered in front of, on or behind the top of the roof.

The soleplate screw 27 is used to adjust the preload of the spring so that only part of the tensioning work needs to be applied. The screw 30 is used to reinforce the spring. Figure 10 shows another embodiment of an overall advantageous ski binding with the individual advantageous elements of this invention, but with swivel jaws 1, 11, which is designed as scissors, the advantages of the scissors jaws 2, 21 and in the heel area further jaws 2, 2t $ which result in an even better ski guide, the rear part of the Sollere being formed from spring leaves, so that when skiing # the distance can be lifted off the ski.

This embodiment is the principle of Drehtellem in ski bindings same, it could also be dispensed with the rear tensioning device and arranged for downhill skiing a tension spring as the one hand fixed to the heel on the ski binding hält.9 on the ski surface and the other hand on a Blechoese of the ski heel is attached.

Such described complete ski binding is despite simple construction optimum performance previously unattainable. Of course, the individual elements themselves are advantageous alone in Xombination with other known elements of Skibindungeh, as the new versatile locking device or the new v I ielseitige clamping device. Since these elements, in particular, interact very advantageously according to the present invention, this results in the optimum function. It is obvious to apply further combinations and explanations than the examples described in accordance with the guidelines for the invention, but all of them without inventive significance.
