"Safety ski binding"

The invention relates to a safety ski binding iait one Holding jaw, which holds the sole of a ski boot on the ski and which is arranged to swing, - however, the impact subject to by a reset device, soft them in the Seeks to hold back the working position or open position, as well as with a bolt that is loaded by an elastic element, which limits the maximum effort that the Jaw can be suspended before unlocking and releasing of the ski boot.

Safety ski bindings, in particular pero bindings, are already known in which the element that holds the sole of the boot on the ski has a certain elastic range of motion that is used before the locking device for this holding element is pushed into the open position. Certain designs of such ski bindings allow the locking device to be reattached, that is to say, the locking device to be closed, even if there is a certain thickness of snow

is present under the sole without any regulation ues Unlocking force is carried out in the event of a security change in the sense of a change. This property is special interesting because it frees the user all measures from the worry that there is snow under his soles "and allows him a quick fixation or removing the skis from the boots.

In this context it should be noted that the j \ jr:, ties, v / elche a certain snow depth; between ski and Allow paragraph, although the elastic bind, mg type innate, but conversely, it cannot be truly described as such, because the depth of snow as a whole is more or less limited in their admissibility or extent by d ^ n elastic path or the amplitude of the elastic movements. There is therefore one with all known bonds Correspondence between elasticity and permitted Amount of snow, whereby the permitted amount of snow is limited by the elasticity. This state of affairs poses a serious disadvantage, because you are forced to use the elasticity in order to achieve a desired length of snow to be able to allow, whereby a dercirt increased elasticity, as it would be required to have a! .. in sufficient groue To be able to allow steep amounts would be undesirable.

The reinforcement of the elastic yoke leads to an increase in the effort that has to be exerted by hand or with a ski pole in order to get the ski boot off the ski. Even the forces that a user of the ski binding can exert are "limited in their amount, and the amount of snow, paradoxically, can also be limited by the physical strength of the skier".

In order to avoid the indicated disadvantages, the safety skin connection mentioned in the introduction is characterized in accordance with the invention in that a device for irreversible movement is built into the kinematic chain between the jaw and the bolt in such a way that the of the bolt continuously closing the sole of the ski boot under the action of the reset device "acted upon, the jaw in the opposite sense and practically without resistance the opening effects emanating from the sole with the elastic element and the latch connects.

In other words, the locking of the Reset device causes while the jaw is still in a high position with respect to the ski, after which the organ, however, is descending. Movement in the sense of an impact or pressure on the sole

senses emanating from the heel of the ski boot transferred from the jaw to the locking device, the latter having a certain elasticity Has character that is exploited before unlocking. JDieee's approach has two advantages: The fc one is that the inventively designed

Safety ski bindings have a significant ability to take up of snow without elastic forces are claimed, while the other advantage is that it automatically adapts to all possible heights of ski boot soles without readjusting the binding force is required.

The aforementioned device for irreversible movement can be firmly connected to the clamping jaw of the ski binding ™ and they with a downwardly depending part of the locking device block, it can be firmly connected to a part of the locking device and this block with the clamping jaw, and it can also be firmly connected to both and one in relation to the other block in one sense of movement, while it practically leaves the two parts free in the other sense of movement.

There can be all conceivable facilities for an irreversible Movement that appear appropriate to be used, such as for example a control curve or an angle, or a device that is designed in the manner of a freewheel is or a device in which a spring in a Recess is added, which is coaxial with the spring and which, when stressed, lies blocking against the inner surface of the recess and causes the blocking.

In a preferred embodiment of the one formed according to the invention Safety ski binding, the device for irreversible movement is designed so that it clicks onto the locking device acts and this automatically gives a shift towards the opening, the amplitude of which increases the grain Fixed or allowable amount of snow.

In a further embodiment of the Sioherheitaskibind formed according to the invention, the submission to; irreversible movement of the locking device ^: independent and acts on the clamping jaw to fix the amount of snow that has been drawn:

It should be noted that the device for irreversible movement at least partially as a locking device _; can serve.

It is particularly advantageous if the device for irreversible movement for the purpose of opening can be expressed with a relatively weak energy, namely in the Way that the skier can easily get the ski boot out of the binding without difficulty.

The ski binding formed according to the invention is special Dimensions suitable for heel or perse bindings, but it is evident that certain principles of the invention can be applied to bindings that grip the toe of the shoe without departing from the essence of the invention.

This means that the ski binding is opened by actuating this element 13 can be. '■

A lever 14 is articulated on the oscillating support piece 5, which forms a pawl 15 at one end, which on a inclined edge 16 acts, the Yerlauf forms an arc shape, which runs concentrically to the pivot axis 3 and is formed by a part of the body from which the clamping jaw 2 consists. The other end of this lever 14 has a control cam 17 which acts directly on the lever in the form of a roller or a ball 7. The lever 14 is mounted on the oscillating support piece 5 by means of an axis 18.

A lever T9. _a, which forms a pedal, is also mounted on the pivot axis 3. The end of the lever, which is opposite to the part which forms the pedal, forms a stop 20 which acts on the pawl 15 and whose task is to move the oscillating support piece 5 <

retract into the locked position, the Pawl 15 is then released again and takes effect and bearing on the curved edge 16 returns.

A reset device tries to keep the jaw 2 in the working position. This reset device has a knee joint, which consists of a tension spring 21, which is formed between a stationary abutment, for example through the axis 12, and a further abutment 22 on the jaw 2 is stretched out by an axis or a pin is formed which runs transversely through the jaw 2. The pivot axis 3 of the jaw 2 is therefore on. one Place arranged between the two abutments 12 and 22 and also occupies a position such that the spring 21 endeavors to put the jaw in the working or active position to hold and to 'pull against the sole of the ski boot 1, as long as the two abutments 12 and 22 do not Assume the overlap position with the pivot axis 3. On the other hand, however, the spring also strives to the clamping jaw 2 in the To retract the open position, namely when the abutment 22, for example after an impact running in the perpendicular direction has acted on the boot 1, was moved beyond the escape position. The ski binding designed according to FIGS works as follows:

BATH ORIGINAL

109825/1334

In the normal working position, the ski binding is in the position, as in the 5 ¹ Ig. 1 and 4 is reproduced. In this working position, the bolt 7 is received in the recess 6, which belongs to the oscillating support piece 5, and the lever 14 is pushed back by the Eiegül 7 »which touches its cam 17, while the other end forms a pawl that rests against the inclined Control cam μ 16 pushes and holds the clamping jaw 2 locked in the working position. The spring 21 tries to keep the jaw in this working position. As for the lever that forms the pedal 19, it is ineffective and its end that forms the stop 20 is out of contact with the pawl 15.

For example, if the skier falls forward, then the heel of the ski boot 1 pushes the jaw 2 upwards. At the beginning of this stroke, the jaw 2 assumes the position | which is shown in Fig. 2, and it causes a Entrainment of the swinging or pivotably mounted support piece 5 by means of the pawl 15 the entire device or arrangement, which from the jaw 2 to the swinging support piece 5, the lever 14 and that part that forms the pawl 15 as one piece, which is pivoted about the pivot axis 3, although this

Due to the movement of the control cam 17 of the lever 14 ■ moved past the latch 7, past migrates to which also the depression 6 [with preceding compressive stress of the spring. 8 The roller or ball which forms the bolt 7 is, however, pushed back in the direction of the oscillating support piece 5 and thereby causes a rotation of the lever

14, by which the pawl 15 is rotated clockwise about the axis 18 and stops pressing against the inclined curve 16 of the jaw 2. The jaw is then in a completely free state and is both by the heel of the ski boot 1 and by the knee joint under the action of the spring 21, the abutment 22 of which is then beyond the line of flight caused by the hni ^ '- ■■ ■■> abutment 12 and 22 and the pivot axis 3 when looking at FIG. 3 runs.

Part of the lever 14 acts and. As a result, the pawl 15 lifts off the inclined curve 16.

It should be mentioned, that a small spring or a stop can be provided to the angle of rotation that the lever 14 with ■ the pawl 15 can move back around the axis 18 to limit.

If the skier wants to fasten the ski again, he puts the ski boot 1 in the binding, which is in the open position, as in Pig. 3 is shown. He presses with the heel of the ski boot els, on the pedal 19. The pedal then takes the jaw 2 over the stop 20 'during the downward movement. Immediately before the movement of the pedal, the stop 20 of the pedal moves into contact with a part 23 of the pawl 15, in such a way that the latter is pushed back upwards and thereby the swinging support piece 5 takes along and rotates via the axis 18 about the pivot axis 3 \.

If the hell or the bolt 7 in the immediate vicinity of the Well 6 arrives, then it begins to bump against the cam 17, and the pawl 15 is then also on the inclined edge 16, and the roller or pawl then enters the associated recess, which is from the '

Recess 6 is formed, a. The edge can be used for relief this latching process can be slightly beveled or stepped. The knee joint formed by the spring 21 acts on the jaw 2 and closes it again against the heel of the ski boot 1. This movement becomes duroh the particularly suitable shape of the pawl 15 allows, which allows a sliding movement on the inclined edge 16, while the jaw 2 in the counterclockwise direction is rotated about the pivot axis 3. After the turning movement around the axis 18 and after the cam 17 has moved past the bolt 7 from below, the frees itself Part 23 of the pawl 15 from the stop 20 such that the Pedal 19 itself can also drop down freely under the action of the heel of the ski boot 1 «.

If the skier would like to release his ski by hand, it is sufficient to compress the spring 8 that is on the latch 7 acts by putting pressure on the end 13 of the lever 11 like. Fig. 4 is exercised. The bond is made at that moment then unlocked, and you can then easily remove the heel of the boot 1.

It consists essentially of the same parts as the "already explained version. A base plate 3? And a jaw 2 are provided to hold a ski boot 1. The jaw 2 can be pivoted about a fixed pivot axis 3, about which the" oscillating Support piece 5 is rotatable, which has the recess 6, which is used for the engagement of the bolt 7, which, however, is claimed by a tension spring 8 i. In the same way, a knee joint is provided, which is formed by a spring 21, which is held with one part on the jaw 2 on the abutment 22 and with the other part on a stationary abutment 12, and which strives to the jaw 2 to keep in contact with the sole of the ski boot 1. The oscillating support piece 5 has an extension 24, at the end of which a clamping lever 26 is held via a hinge 25. On an axis 27, which is supported on the extension 24 of the oscillating support piece 5, a lever 28 is mounted, which is an axis

29 carries around which a second clamping lever 3 0 is pivotable. A spring 31 * between the two tension levers 26 and

30 is arranged, tries to pivot them in such a way that their other ends approach each other and clamp between them a handlebar 32, which has a joint 33 is held on the jaw 2. This handlebar 32- is

Also this version of the ski binding has, like the one already mentioned, in the same way a pedal 19, of which a plate is formed, which can be moved with one end near the heel of the ski boot in a guide 37 that is supported by the swinging one Carrying piece 5 is held. This plate, which forms the pedal 15, is articulated at the other end on an axis 38, which is connected to a lever 39 which, in turn, can be pivoted about an axis 40, which is also held by the swinging carrier piece 5 .

The safety ski binding shown also has an opening lever 45 which is held on a joint 46, which is fixedly arranged, while a rod 47 engages via a joint 48 on the opening lever 45 and via a The other end of the pin 49 is attached to the oscillating support piece 5. The connection between the pin 49 and the rod 47 works as a sliding connection created by an elongated hole 50 which is provided in the end of the rod 47. The actuation element, which is used to move the opening lever 45 by hand, forms an end 51.

The function of this second embodiment of the invention The trained safety ski binding is comparable to that of the previously explained design. At this second embodiment, the device becomes irreversible Movement formed by the clamping levers 26 and 3 ^, which act against the handlebar 32.

When the skier falls forwards, the jaw 2 is pushed upwards and takes along the oscillating support piece 5 via the mediating effect of the link 32 and the clamping levers 26 and 30. The spring 8 is also compressed, and the bolt 7 leaves its recess 6 and rolls over a neutral profile of the oscillating support piece 5, the compressed state of the spring ⁽

8 is maintained. The swinging support piece 5 rotates around the pivot axis 3, while the ^ olle 35 on the Control cam 36 increases and an angular movement of the lever 28 enables clockwise and a reduction in the spring tension 31 is generated. By reducing the spring tension the spring 31, i.e. the compressive stress of the same, takes place a reduction in the tensioning effect which the tensioning levers 26 and 30 exert on the handlebar 32 takes place. This handlebar 32 slides therefore with respect to the levers 26 and 30 until the stop 34 makes this movement to open the jaw 2 with respect to the Extension 24 of the oscillating support piece 5 is limited. Since the connecting line between the spring abutment 22 and the spring abutment 12 of the spring 21 during a increasing movement of the spring the pivot axis 3 happens, a lifting of the jaw 2 is caused by which the Boot 1 is fully released. The bolt 7, which is pushed out of the recess 6 in this state acts on the piston 42 and pushes it by the spring 44, whereby a displacement of the lever 39 takes place, which the pedal 19 and the clamping jaw 2 pushes.

To reattach the ski, it is sufficient if the heel of the boot 1 is pushed onto the pedal 19 and this causes a downward movement. These

then has a rotation of the oscillating support piece 5 As a result, the bolt 7 engages again in the recess 6 in the course of the same. This in turn becomes the pedal 16 ■ actuated. Me jaw 2 then continues the descending movement, because it is taken along by the spring 21, see above that the cheek finally the heel of the shoe "or ski boot and pulls against the base plate P of the ski i, even if there is a lump of tendons Ii formed between the heel of the ski boot and the base plate P. The clamping levers 26 and 30 act again on the handlebar 32 because the roller 35 has come into contact with the cam 26 again. The clamping levers 26 and 30 in no way affect the continuous, downward movement of the jaw 2 within the permissible range Limits, as they also have different sole heights of the boot 1 and possibly different heights of the Even out snow under the heel of the boot. The downward movement of the jaw 2 always takes place according to the respective needs in order to make the corresponding height adjustment.

For example, when the skier wants to loosen the ski, he bumps with the ski pole on the opening lever 45, which has a compressive stress on the spring 8 as well

It has a cheek 2, with which a ski boot 1 on one Ski is held, which is represented by a base plate P. The jaw 2 can be pivoted about an axis 52. This axis 52 connects the jaw to a swing-mounted support piece 5 which is mounted on a pivot axis 3 is. The pivot axis 3 in turn is held in a support which is fixedly connected to the ski binding. That oscillating support piece also has a recess 6 which is used to engage the latch 7, which is through a Spring 8, which is arranged in a recess in the fixed support 4, is acted upon. Firmly with the bolt 7 a pin 53 is connected. The pin 53 is itself connected to a lever 55 via a hinge 54 so that it can act on one end 56 of this lever 55 has the consequence that the bolt 7 emerges from the latching recess 6 against the action of its spring 8 which loads it.

109825/1334

The vibrating support piece 5 carries an axis 57 for one. '; Lever 58, one end 59 of which forms a pawl, which with an ascendingly inclined curve edge 60, which immediately is formed on the jaw 2, cooperates. This curve edge 60 has an essentially cylindrical shape » and the cylinder runs concentrically to the axis 52. Between the jaw 2 and the swinging support piece 5 is a knee " joint formed. This knee joint is held by a compression spring 61 created, with one end via an abutment 62 on the oscillating support piece 5, with the other end via an abutment 63 acts on the jaw. As can be seen from the figure, the pressure abutment 63 of the spring 61 is on a point arranged between the pivot axis 52 of the jaw 2 and the pressure abutment 62 on the oscillating support piece 5 lies.

A. Pedal 19 is movable about pivot axis 52. This | Pedal 19 is equipped with an ArEDhlag 20, which is used for this serves to act on the jaw 2.

The aforementioned embodiment of the safety ski binding works as follows;

In the event that the skier falls forward, it rises the heel of the ski boot 1, so that the jaw 2 with attached

-22-

is lifted, which also takes the pedal 19 with it during this movement and also gives the oscillating support piece 5 a corresponding movement, because this oscillating support piece is temporarily and temporarily firmly connected to the jaw 2, as can be seen from FIG. The ack 2 is provisionally or temporarily firmly connected in this way to the oscillating support piece 5, because a device for irreversible movement comes into effect, which is formed by the pawl 59 and the curved edge 60 cooperating with it. The unit, formed from the components 2.5> 19 and 59 »rotates under the load of the falling skier about the pivot axis 3 and in this way causes a jerk stress on the spring 8, which has the result that the bolt from its detent -well 6 emerges. In a practically realized embodiment of this ski binding, which is shown in Fig. 10, this bolt 7 is held in a non-rotatable manner by a simple claw or a finger, while in the schematic representations which show FIGS. 6 to 9, as a bolt; a ball is provided which is able to roll on a neutral curve profile 64 that is in immediate; läh the Rast'vertiefung 6 is provided on the swinging support piece 5.

If the position is to hit a stop 66 with its end 65, the pawl 59 is lifted from the inclined curve edge 60, which in turn has the consequence that the jaw 2 can be pivoted about the axis 52. From this moment the movement of or on the basis of this movement, the platen 63 moves from the bottom upwards above the line also passing through the pivot axis 52 and the "thrust bearing 62 and the ^ 'irklinie of the spring 61 is defined. The knee joint action therefore occurs, and the jaw 2 is pulled even further upwards by the spring (Pig. 8) and the ski boot is released. The spring 61 is selected to be sufficiently strong, because the process of reattaching the ski is initiated in that pressure is exerted on the pedal 19 with your heel. The pressure that is generated in this way has the "consequence that the unit, which is formed from the jaw 2, the pedal 19 and the oscillating support piece 5, is lowered about the pivot axis I 3 and the latch 7 moves along the neutral profile of the curved edge 64 until it engages the recess 6 and in this way causes the locking mechanism, the locking being achieved before the jaw 2 is pivoted about the axis 52 (Fig. 9). has hit in the closing direction.

In this way, the oscillating support piece 5 has its own again

assumed lower position, the lever 58 being put into position, against the fixed stop 67 about the axis 57 to pivot so that the pawl 59 interacts with the inclined edge 60 of the curve anew. The downward one Movement of the ski boot 1 is sufficient to achieve that the pawl 59 slides over the curve edge 60. This results in the possibility that the jaw 2 is placed against the sole of the ski boot again. This movement of the jaw 2 takes place under the action of Spring 61. This movement takes place when the paragraph of the Ski boots or the snow underneath comes into contact with the ski, the snow possibly touching the ski covered (Fig. 10).

Fig. 11 shows the principles of the application of a device for irreversible movement in which a helical spring 68 is used, which is arranged in a cylindrical recess 69 which is partly in the Jaw 2 and the other part in a support 70 is located. The cylinder axis of the recess 69 for the spring falls with the pivot axis of the jaw 2 together. As can be seen from Fig. 11, the arrangement is made so that the Spring 68 blocked in recess 69 when jaw 2 tries to lift while the jaw is released,

when she wants to lower herself onto the sole of the ski boot. A lever 71 is arranged in the recess 69. An end 72 of this lever engages an angled end 73 ^ he spring 68. It can be seen without difficulty that a counterclockwise movement of the lever 71 results in "tensioning" the spring in the recess 69 by taking along the angled At the end of 73. This “tensioning” reduces the external diameter of the helical spring 68 and jaw 2 is released with respect to spring 68. The spring 68 is in the opposite direction of movement, i.e. clockwise, taken when the Tried to lift jaw 2. The friction between the spring

68 and the recess walls surrounding the recess

69 induce a relaxation or winding action which is exerted on the spring and which leads to an increase in the outside diameter of the spring. This enlargement of the outer diameter in turn causes blockage of the coil spring 68 with respect to the recess 69. ^Because of this behavior is the jaw 2 always able to lie firmly against the heel of the boot and corresponding movements of feeding e τ · η, while: it blocks against any lifting movements of the heel and corresponding inclinations of movement of the jaw, so that the jaw 2 and the support 70 form a unit.

The disengagement of such a body to become irreversible Movement requires practically no energy, so opening a ski binding with such a device equipped, can be carried out with great ease. It goes without saying that the relocking happens with the same ease. It is only to achieve that the surface of the Yifindungen the helical spring (in the illustrated embodiment, the outer surface) against the corresponding Surface of the recess lays in which the Pe the is recorded.

The Pig. 12 shows the schematic representation of a ski binding, which is equipped with the device according to Pig, 11.

As can be seen from FIG. 12, a control cam 77 is provided, at one end of which the recess 6 lies, while the other end has an arcuate rounding "78. A stop 79 terminates this control cam 77. The tension of the spring 8 leaves change by means of an adjusting screw, which is not shown in the drawing, the cam 77 is not arranged concentrically to the pivot axis 3, so that the spring 8 is tightened and stressed by more, the more the support piece 5 rotates about the axis 3 away from the ski. It turns out, however, that the position shown in the figure represents the rest or stable position. However, the rounding 78 of the control curve 77 allows the setting of a further stable or rest position of the oscillating support piece 5 after a slight decompression of the spring 8. However, as long as the bolt has not reached the rounding 78, the oscillating support piece 5 is constantly striving to return to the position honor shown in Fig. 12 so that the heel ski binding
