EP0054928A1 - Combination of a touring ski binding and a ski brake - Google Patents

Abstract

A ski has a safety binding which includes a support for a ski boot. The support carries retainers for the toe and heel of the boot and is pivotable about an axis extending transversely of the ski so that the ski boot may be swung away from the ski during skiing. A brake for the ski is mounted on the support and is arranged to be kept in an inoperative or non-braking position by the pressure of the ski boot. The brake is resiliently urged towards its operative or braking position and automatically moves to this position when the pressure of the ski boot is released. The ski is thus braked regardless of whether the boot is removed from the binding intentionally or unintentionally.

Description

The invention relates to a touring binding with a touring swivel part which has sole holders for the ski boots, is pivotably mounted about an axis running transversely to the longitudinal axis of the ski and can be fixed for downhill skiing, and with a ski stopper.

With touring bindings of this type, it has previously been customary to secure the ski that comes free from the boot with a safety strap. Although this is appropriate for deep snow descents, modern touring bindings that are designed as safety bindings and can be attached to the ski are just as suitable for downhill skiing on slopes. In this case, the use of a safety belt is rejected by the skier because of his own risk of accident, which is caused by the ski hanging loosely on the safety belt and connected to the ski boot. The previously known alternative to a safety strap, namely a ski stopper, has already been used in conjunction with touring bindings, but in this known arrangement the ski stopper is only effective after an involuntary triggering operation of the safety part of the touring binding, since it is due to a special device on the ski is held as long as the safety part of the touring binding is not triggered. In cases in which the skier has released the skis from the boot without being involuntarily triggered, for example in the event of a fall, the ski stopper was held in the inoperative position. This is a considerable disadvantage for a ski binding in that skiers often do that Arbitrarily detach skis from boots. In these cases, however, the ski must also be secured so that it does not slide down the slope in an uncontrolled manner, which can result in accidents or the loss of the ski.

The object of the invention is to provide a combination of touring binding and ski stopper, in which the ski stopper inevitably comes into play, regardless of whether the ski is released from the boot by an involuntary loosening of the safety binding or by an arbitrary loosening of the binding from the boot, i.e. H. the ski stopper may only be held in its inactive position by the boot without additional parts. In addition, the ski stopper should not hinder touring.

This object is achieved in that the ski stopper is arranged on the touring swivel part.

By arranging the ski stopper on the touring pivoting part, i. H. on a touring plate or on a touring frame, this ski stopper is held in its inactive position by the boot resting on this touring frame or the touring plate. As soon as the ski boot comes free of the touring swivel part, the ski stopper comes into the effective position due to a spring force and brakes the ski or prevents it from slipping. The ski is therefore always secured, regardless of whether the boot is released due to a triggering process of the safety part of the touring binding or by arbitrarily opening the binding. Additional parts that hold the ski stopper in its inactive position are therefore no longer required.

In order to be able to use only a lanyard but not a ski stopper on long runs in deep snow, the ski stopper is detachably arranged in a further development of the invention. As a result, the ski stopper can be removed in a simple manner when using safety straps, so that it does not pose any risk of accident if the ski is held on the boot by the safety strap and the ski stopper is in the effective position in which it is due to the loose connection by Lanyards of ski boots and skis could endanger the skier.

An advantageous embodiment of the invention in connection with a touring frame designed touring swivel part and a ski stopper, which has a bearing part for a brake bracket, in that the bearing part has on its outer regions receptacles that serve to hold the ski stopper on the step frame and that on the bearing part Locking device is provided, which fixes the bearing part with respect to the longitudinal direction of the touring frame.

This configuration achieves the task of arranging the ski stopper on a touring frame in such a way that there is no impairment of the safety release part arranged on the touring frame and the length compensation, that is to say that no forces are transmitted from the bearing part of the ski stopper to the touring frame which lead to deformation thereof could, since the restoring forces of the brake bracket can be absorbed by the bearing part, regardless of whether it is an elastically deformable brake bracket without additional Return spring or a ski stopper, in which the brake bracket is pulled or pressed into its effective position by additional springs.

The bearing part can be constructed from two bearing blocks and a connecting web connecting the bearing blocks, and the bearing blocks can be provided on their sides running parallel to the ski edges with receiving grooves for the legs of the step frame. In connection with a locking device, which is designed as a pivotable on the bearing part spacer, which can be snapped with its free end into a recess in a front or rear sole support web, a quick fastening possibility of the ski stopper is created on the step frame, since the bearing part is spread by briefly Leg of the step frame can be snapped between them and can be held in the longitudinal direction by means of the spacer, which also transmits the braking forces to the sole receiving web.

An even faster arrangement of the ski stopper on the touring frame results from an advantageous further development of the invention in that the receiving grooves of the bearing part are drawn inward at least at two diagonally opposite corners of the bearing part and are at a mutual distance which is essentially the distance between the two legs corresponds to the touring frame, whereby the bearing part can be inserted in an entangled position between the legs of the touring part and then brought into its position of use by twisting. In the same way, the ski stopper can be removed from the touring rack quickly. be solved.

If, according to a development of the invention, the bearing part is designed in such a way that the mutual distance between the arcuate receiving grooves in the region of the transition to the straight line is somewhat larger than the distance between the legs of the touring frame, then when the bearing part is screwed in between the two legs, that they are pushed apart for a short time until the bearing part is in its position of use. As a result, a certain snap effect is brought about, which means that the bearing part cannot be brought out of its position of use again without a certain amount of force, as a result of which it is secured between the legs in addition to the locking device. In the position of use, the legs are not loaded by the bearing part, since the distance between the receiving grooves corresponds to the distance between the legs and the support of the bearing part or the entire ski stopper takes place via the spacer on the sole receiving web, so that there is no impairment due to the deflection of the Skis necessary length compensation or the function of the safety release part can occur.

If the spacer is designed as a U-shaped wire bracket and is articulated with its free ends to the horizontally running bearing sections of the brake bracket, it is possible to keep the legs of this wire bracket in the immediate vicinity of the inside of the legs, so that no additional disruptive surfaces between the legs of the kick stand. The pivotable configuration of the spacer brin ^g tganz generally the advantage that this when the ski stopper is removed, it can be brought into a position parallel to the brake bracket, so that no bulky component is formed which can easily be inserted into an anorak pocket if the skier prefers to use a safety strap.

In another embodiment of the invention, the bearing part can be constructed from two bearing blocks and a support part in the form of a shell which partially surrounds the step frame with raised and inwardly bent edge regions and rests against it from below in the use position. This shell can also serve as a spacer and, in a further advantageous embodiment of the invention, can have a latching tongue which can be latched into an opening in a sole receiving web.

If you manufacture the bearing blocks from a plastic suitable for storage purposes and the connecting web or the supporting part from a strong sheet metal, it is possible to absorb the forces resulting from the deformation of the elastic brake bracket completely in the bearing part without the touring frame with them Forces. The control surfaces necessary for the deformation, which, in conjunction with the elastic deformability of the bracket, bring the brake bracket back into its effective position, are provided according to an advantageous embodiment of the invention on the mutually facing sides of the bearing blocks, so that they are simple to manufacture the pedestals can be cast on. If the connecting web is made from two spaced-apart connecting plates which are inclined to one another in such a way that a roof-shaped surface is formed, the advantage is achieved that the snow building up on the ski below the bearing part is divided by the roof-shaped or wedge-shaped bearing part and is pushed apart, thereby avoiding a large accumulation of snow under this part when touring. An impairment of touring by the ski stopper is thus largely avoided, which is not annoying due to its arrangement between the legs and due to its low height in the ineffective position, which at most corresponds to the height of the sole receiving webs arranged on the step frame.

The low height in the inactive position is achieved in a further embodiment of the invention, characterized in that the brake strap with horizontal bearing sections in downwardly open bearing recesses added and obliquely through the above of the bearing blocks is erweiterndenj _l -shaped part under prestress is kept to the outside on the bearing blocks , and that the bearing sections are in the use position below the legs of the step frame. Since the step frame is held in a front bearing and rests on a rear locking device, a small gap between the ski and touring frame remains in the position fixed on the ski, which is sufficient to accommodate the horizontal bearing sections of the brake bracket. Since the brake bracket is held under pretension on the bearing blocks by the Ω-shaped part which widens obliquely upwards, so that it cannot fall down, the bearing recesses can be open at the bottom and only deep enough that the bearing sections of the brake bracket fit into it . This not only increases in height saved, but also the assembly of the brake bracket in the bearing blocks much easier. The brake bracket can namely be elastically compressed to such an extent that it is released by a rotation relative to the bearing blocks and can be pulled down out of the bearing part if a correspondingly large recess is provided in the bearing part carrying the bearing blocks. In the embodiment in which connecting plates hold the bearing blocks together, this is not possible, but these connecting plates can be detached from the bearing blocks in a simple manner by means of a screw connection.

• Fig. 7 is a perspective view of a modified embodiment of a ski stopper.

In the exemplary embodiment shown, only the step frame designated by 1 is partially shown of the touring binding, which has two wire legs 2 and 3 with a circular cross section, which in their front area carry a sole receiving web 4 on which a front sole holder 5 is arranged. The rear sole receiving web with the safety release part of the touring binding is not shown because this is not necessary for an understanding of the invention.

The step frame 1 is pivotally mounted about an axis extending transversely to the longitudinal axis of the ski in a bearing part, not shown in the drawing, so that when touring the step frame can be pivoted up about this front axis, whereby the boot can be lifted off the ski.

Between the two legs 2 and 3 of the step frame 1, a ski stopper, generally designated 6, is arranged in the vicinity of the front sole receiving web 4. The ski stopper comprises a brake bracket 7, which is designed as a spring, which is pivotally mounted in a bearing part 8 and is held in relation to the longitudinal axis of the step frame by a spacer 9 which is pivotably mounted on the brake bracket 7 and which is offset with an offset 9 'into an opening 10 of the front sole receiving web is suspended and supported there, so that the ski stopper is locked at a very specific point on the step frame.

The brake bracket 7, which is made in one piece from a resilient wire, has an upper Ω-shaped part 11 with a tread plate 12 and two horizontally running bearing sections 13 and 14, each of which is connected to a brake arm 15 and 16. The brake arms 16 and 16 have brakes made of plastic shoes 17 and 18, which are attached to the wire ends of the brake bracket 7 and fastened there.

The brake bracket 7 is pivotally mounted with its horizontally running bearing sections 13 and 14 in the bearing part 8, this bearing part being constructed from two bearing blocks 19 and 20 made of plastic with self-lubricating properties and from two connecting webs 21 and 22 arranged on the underside of the bearing blocks.

The bearing blocks 19 and 20 are provided on their underside with roof-shaped surfaces 23 and 24 on which the connecting webs 21 and 22 abut, as a result of which they are inclined to one another in such a way that the adjacent edges of the connecting webs lie at the thickest point of the bearing blocks , which creates a wedge effect on the snow that accumulates on the ski, which prevents icing due to the snow being pressed on the ski below the ski stop.

The bearing blocks 19 and 20 have on their underside in the middle downwardly open bearing recesses 25 and 26 which are so deep that the bearing sections 13 and 14 of the brake bracket 7 are completely accommodated. With its curved transition areas 27 and 28 between the bearing sections 13 and 14 and the adjoining loop-shaped part 11, the brake bracket 7 bears against control surfaces 29 and 30 of the bearing blocks 19 and 20 under prestress. The control surfaces 29 and 30 each have a locking recess 31 or 32 in the central plane of the bearing block, in which the brake bracket 7 is held in its effective or braking position. In order to pivot the brake bracket out of this position, it must be pressed over the inwardly projecting locking cams 33 and 34, which directly adjoin the locking recesses 31 and 32 and one Compress the loop-shaped or Ω-shaped part 11 of the brake bracket when it is pivoted forward in the direction of the sole receiving web 4 by the attached boot into the inactive position. This deformation results in the restoring force which returns the brake bracket to its braking position, in which it is received in the locking recesses 31 and 32, when the boot comes free from the step frame 1, so that the holding force exerted by the boot on the brake bracket 7 stops. In the ineffective position, which is shown in Fig. 1, the Ω-shaped part 11 of the brake bracket is between the legs 2 and 3, while the brake arms 15 and 16 are parallel to these legs on the outside of the step frame.

To hold the ski stop 6 on the step frame 1, the bearing blocks 19 and 20 have on their side surfaces parallel to the outer ski edges receiving grooves 35 and 36, which are adapted to the shape of the legs 2 and 3 and fit essentially tension-free between them. At diagonally opposite corners, the receiving grooves 35 and 36 are rounded inward, the arcuate receiving grooves 37 and 38 also being at a mutual distance which essentially corresponds to the distance between the two legs 2 and 3 of the step frame. In the transition area between the linearly extending receiving grooves 35 and 36 and the arcuate receiving grooves 37 and 38, the mutual distance between these sections, designated 39 and 40 and serving as locking cams, is somewhat larger than the mutual distance between the legs 2 and 3 of the step frame 1.

The ski stopper is inserted into the step frame in such a way that the bearing part 8 is inserted in an entangled position between the legs 2 and 3 of the step frame, the displacement of the bearing part relative to the step frame being carried out in such a way that the arcuate receiving grooves 37 and 38 pick up legs 2 and 3. After a rotation of the bearing part, the locking cams 39 and 40 briefly pushing apart the legs 2 and 3 of the step frame, the legs 2 and 3 enter the receiving grooves 35 and 36, as a result of which the bearing part is in the position of use shown in FIG. 1. The legs 2 and 3 spring back elastically after the locking cams 39 and 40 are exceeded during the turning process. In this position of use, the bearing part is fixed by the pivotable spacer 9 in that this spacer, which is designed as a U-shaped wire bracket, is inserted with its offset 9 ′ into the opening 10 of the sole receiving web 4. The spacer 9 is designed so that it rests on the inside of the legs 2 and 3 on these in the use position.

In the position of use recorded between the legs 2 and 3, the bearing part 8 is held in such a way that the horizontal bearing sections 13 and 14 rest against the legs 2 and 3 from below. Since the Ω-shaped section 11 widens upwards and rests against the bearing blocks with pretension, the brake bracket cannot fall out downwards.

In Fig. 1, an arrow is drawn, which indicates the direction of rotation in which the bearing part 8 must be moved in order to bring it out of its position of use between the legs 2 and 3 again.

In the second embodiment shown in FIG. 7, the ski stop designated as a whole comprises a bearing part 46 on which bearing blocks 41 and 42 are arranged, which on their mutually facing sides are provided with control surfaces 43 and 44 corresponding to the control surfaces 29 and 30 in the first exemplary embodiment are used to deform the brake bracket 7 when it is pivoted. The bearing part 46 also has a support part 47 connecting the two bearing blocks 41 and 42 to one another, which is designed as a shell and has upwardly and inwardly curved edge regions 48 and 49, in the longitudinal direction of the step frame, of which the legs 2 and 3 of the step frame in the position of use of the ^p Skistop ers 45 are partially, wherein the bearing blocks 41 and 42 bear in this position of use on the inside of the legs 2 and 3. FIG. In order to be able to bring the ski stopper 45 into the position of use, the edge regions 48 and 49 are elastically bent outwards so that the legs 2 and 3 of the step frame 1 into the one through the edge regions 48 and 49 on the one hand and the outer sides 50 and 51 of the bearing blocks 41 and 42 on the other hand, formed recordings can snap into place, which is not possible without this deformation, because the edges 52 and 53 of the edge regions 48 and 49 come so close to the outer sides 50 and 51 of the bearing blocks 41 and 42 that this remaining distance is smaller than the diameter of the Legs 2 and 3. As a result, the ski stopper 45 is held on the step frame 1, with the locking on the step frame, ie the fixing of the ski stopper at a specific place on the step frame, by means of a locking tongue 54 formed on the shell 47, which engages in the opening 10 of the sole receiving web 4 can be snapped into place. The shell 47 thus takes over the functions of the connecting webs 21 and 22 for the bearing blocks 19 and 20 and the spacer 9 in the embodiment according to FIGS. 1 to 6.

In order to fix the ski stop on the touring frame, it is also possible to arrange the bearing blocks 41 and 42 displaceably on the shell 47 in order to prevent the edge regions 48 and 49 from bending apart if the shell 47 is produced from a material which does not have the necessary elasticity Features that are necessary to be able to bend the edge areas so far apart that ^* a recording of the legs 2 and 3 between the bearing blocks and the edge areas is possible.

The tread plate 12 can also be arranged pivotably on the Ω-shaped part 11 of the brake bracket 7 in order to facilitate the pivoting of the brake bracket by the ski boot.

As in the first embodiment, the bearing blocks 41 and 42 are provided on their underside with downwardly open bearing recesses 55 and 56, in which the horizontal bearing sections 13 and 14 are completely accommodated. The brake bracket is also here due to the Ω that widens upwards. -shaped part with pretension between the bearing blocks, so that it can not fall down despite a recess 57 in the support member 47. The recess 57 in the support part 47 is necessary so that the brake bracket with its horizontally running bearing sections can be arranged below the legs 2 and 3 of the step frame. On both sides of the recess 57, support tabs 58 and 59 of the supporting part 47 are bent downward and form inclined surfaces on which the bearing blocks provided with corresponding inclined surfaces rest, as is the case with the first embodiment and can be seen particularly clearly from FIG. 3.
