U.S. Patent Application No. filed October 21, 1980
No. 198133, currently U.S. Patent No. 4,366,968, pending U.S. Patent Application No. 358372, filed March 15, 1982, entitled Ski Brake. Publication No. 368,276 (U.S. Pat. No. 4,470,614), filed on April 14, 1982, entitled Ski Brake, has attracted attention. All of these are assigned to the assignee of this application, and all of these relate to ski brakes.

Other ski brakes often use a piece of wire in the form of a lever with an axle pin between the upper and lower arms of the lever. The lower arm forms the prong of the brake and extends below the ski when in the braking position. These lower arms are
When in the non-braking (i.e., skiing) position, it rotates above the bottom of the ski. However, in this ski brake,
Even when in the braking position, the brake prongs extend outward from the ski. This may cause one of these brake prongs to become engaged with other objects, such as the brake prongs of other skis, thereby endangering the skier's safety. It is therefore highly desirable to minimize this risk by using a lever that is pulled towards the inside of the ski in the non-braking position.

The so-called turntable ski binding shown in U.S. Pat. No. 4,035,001 is a very useful ski binding. It is designed to rotate somewhat within the fastener. To adapt a ski brake to such a binding, it is necessary to provide means for limiting the frictional resistance between the ski boot and the ski brake, so that the ski boot and the heel retention element of the binding can still rotate. It is desirable to do so. Additionally, it would be desirable to include means for selectively controlling movement of the ski binding, such as during ski transport.

Additionally, it is desirable to minimize the height of the boot sole above the ski.

SUMMARY OF THE INVENTION The present invention provides a ski brake in which the brake prongs are drawn toward the inside of the ski when in the skiing position.
The invention further features a pedal and turntable arrangement that allows the boot to rotate within the turntable binding. The present invention
It also provides means for selectively controlling the rotation of the heel retainer within the turntable binding. The invention further features a construction that minimizes the height to which the boot is raised above the ski.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, the ski stopper of the invention is shown for use with a so-called turntable ski binding. Such turntable ski bindings are known in the art and are disclosed in U.S. Pat. No. 4,035,001, herein identified by number.
Bindings), with Roland Jungkind as the inventor, and Hannes
Marker (Hannes Marker) as the transferor,
It is detailed in the specification issued on July 12, 1977. Figures 1 and 2 attached hereto show portions of a turntable fastener. A turntable 1 is held on a ski 3 by a retaining disc 2, which is itself fixed to the ski by a set of screws 4;
Only one of the screws is shown. The turntable 1 is capable of horizontal turning operation limited to some extent in each direction. The turntable 1 has two upper flanged side walls or side cheeks 5, 6. A pair of tension bars 7, 8 (only some of which are shown) are rotatably installed in holes in the side walls 5, 6. The other ends (not shown) of the tension bars 7, 8 carry a sole retention element (not shown) which is movable against the force of at least one spring and which is Engages with the heel of the shoe.

Thus, while skiing, the sole retention element is what holds the boot to the ski.
However, in cases where it is desirable for the ski boot to come off, such as during a fall, the ski boot and the turntable are designed to rotate somewhat, making it easy for the ski boot to come off.

To explain the ski brake of the present invention,
FIG. 1 shows a bridging member 9 formed at the rear of the holding disc 2, which bridges the rear of the turntable 1. FIG. Ski brake board 10
is attached to the ski adjacent to the rear end of the bridging member 9. Ski brake board 10
has a wall 11 with a flange thereon, which supports a transverse axle 12 which is rotatably movable. One end of the actuation arm 13 is
It is attached to the mandrel 12 so that the actuating arm is rotatably arranged on the base plate 10. The other end of the operating arm 13 is rotatably mounted near the rear of the pedal 14 by a bolt 15 that is slidably received in a slot 16 formed in the pedal 14. . The actuation arm 13 can rotate around the bolt 15. Furthermore, the actuation arm 13 is capable of some sliding movement along the pedal 14 as the bolt 15 slides within the slot 16.

The ski brake further includes a pair of levers 17, 1 rotatably attached to the front of the pedal 14.
8 in the form of lever means. The configuration of each lever can be better understood with reference to FIG. 2, which is a partial cross-sectional view with the upper half of the pedal 14 removed. Preferably, the levers 17, 18 each consist of a single piece of round cross-section wire. As best seen by looking at lever 17,
Each lever has a lower arm 19 and an upper arm 2.
2 and has a central connecting portion 21 between them. The lower arm 19 has a plastic cover 20 at its free end and a brake prong.
The prongs extend below the ski and act to bite into the snow when the ski brake is in the braking position as shown in FIG. The central connecting part 21 acts as a pivot pin between the lower arm 19 and the upper arm 22. Thus, when the upper arm 22 is raised, the lower arm 19 rotates down and into position for applying the ski brakes. When the upper arm 22 is pushed down, the lower arm 19
It rotates up and comes to a position where it does not extend below the ski and does not apply the brakes.

The horizontal shaft 12 is equipped with a coil spring 26. The center part of the coil spring 26 is connected to the actuating arm 13
It has an activation leg 27 for engaging.
Each end of spring 26 has a base leg 28 for engaging substrate 10. The spring 26 is
It serves as a means for biasing the actuating arm into the upward operating position shown in FIG.
The flanged wall 11 above the base plate 10 is covered by a lid 29 fixed to the base plate 10 with rivets 30. The rivet 30, together with the lid 29 and the wall 11 with a flange on top, is attached to the lever 17,
It forms a base for 18 shaft pins 21.

As best seen in the upper part of FIG. 2, a guide surface 25 is formed on the underside of the pedal 14. The guide surface 25 is configured to engage the upper arm 22 of the lever 17, 18 when the pedal is depressed. The lower part of each guideway is closer to the center of the ski than the upper part. Thus, the guide surface 25 first touches the upper arm 22 of the lever.
When engaged, the lever is away from the midline of the ski, but as the pedal 14 is depressed further, the guide surface 25 advances the upper arm 22 inwardly toward the center of the ski, and the lever moves away from the midline of the ski. carried inside.

The operation of these various parts of a ski brake can be understood more fully by considering how a ski brake moves between a braking position and a skiing position. FIG. 1 shows the ski brake in the braking position, which means that the lower arm 19 extends below the bottom surface of the ski 3. FIG. When the boot is inserted into the binding, the rear part of the sole engages the pedals 14.
As the pedal 14 is pushed down, the lever 1
7, 18 rotate about their respective axle pins 21 until the lower arm 19 of the lever rises above and approximately parallel to the ski. This rotation is done against the force of spring 26 which biases actuation arm 13 into the actuation position shown in FIG. As the pedal 14 is further depressed, the bolt 15 slides forward within the slot 16. Thus, further depression of the pedal 14 causes the actuation arm 13 to stretch the spring 26, but the extra force must be applied due to the spring force provided by the pedal and the actuation arm. is relatively small.

Depressing the pedal 14 causes the upper arm 19 of the lever to engage the guide surface 25 on the underside of the pedal. This means that the levers 17,1
8 facing each other inwardly, at least the lower arm 1
9 so that most of it is in a position inside the width of the ski (as shown in the lever 17 in the upper half of FIG. 2). In this way, the risk of the levers of other skis catching on the levers of this ski is reduced. That is, in the braking position the lower arm 19 is on the outside of the ski, meaning that it extends past the side of the ski, whereas in the non-braking position In this case, the lower arm 19 is located towards the inside of the ski, which means that at least a large part of the lower arm lies within the width of the ski. As used herein, the term "inwardly" refers to the possibility that a portion of the lower arm 19 extends outwardly beyond the side of the ski, as shown on the above side of FIG. It should be understood that this also refers to gender. The important thing about the inward position is that the lower arm 1
The free end of the 9 is on the side of the ski, reducing the inherent risk of the brake sticking out while skiing.

When the pedal 14 is released, the spring 26 moves the working arm upwards, which then pulls the pedal 14, then the upper arm 22, and rotates the lower arm 19 down into the braking position, so that the ski The brake will move to the position where the brake is applied.

Other refinements of the invention are also shown in the drawings.
The end of the upper arm 22 of each lever is bent inward toward the center of the ski and reduces in diameter to form a mounting prong 23. A spring 24 is provided between the two levers 17, 18,
It is held in place by a mounting prong 23 at the end of each upper arm. Therefore,
The spring 24 acts as a biasing means to release the levers 17, 18, so that each lower arm 19 moves to the outside of the ski when the levers are in the braking position.

The turntable 1 further includes a metal support piece 31 and a plastic shoe plate 32. This plastic shoe plate has two holding discs.
It extends in the shape of a horseshoe around the. The open side of the horseshoe-shaped plastic shoe plate 32 faces towards the rear of the ski, thus providing an open area above the retaining disc 2 for accommodating the pedals 14. When the ski boot presses down on the pedal 14, the pedal 14 is received within the opening by the horseshoe-shaped shoe plate 32. Each time the pedal 14 is depressed, the boot is engaged with the shoe plate 32.
Preferably, the weight of the shoe is carried by the shoe plate 32 rather than by the pedals 14 while skiing. Thus, when the turntable is in motion, such as during a fall, friction between the shoe and the pedals 14 is kept to a minimum.

The rear part of the pedal 14 extends beyond the actuation arm 13. This extension 33 serves the purpose of engaging a sole retention element (not shown) of the ski binding. In this way, when the ski binding is in the position shown in FIG. 1, the ski binding is prevented from rotating. Such engagement methods are known in the art, for example as shown in U.S. Pat. No. 4,366,968, in which a turntable ski binding is coupled to a sole retention element. A pedal is provided with a pawl arm for engagement to prevent rotation of the retaining element. This is desirable, for example, when transporting skis.

The outer diameter of the spring 24 is no larger than the wire diameter of the levers 17,18. Since neither the pedal 14 nor the component 32 needs to be enlarged to accommodate the spring 24, the size of the pedal 14 as well as the size of the plastic part 32 of the turntable 1 can be kept small. Therefore, the heel of the ski boot does not need to protrude significantly above the ski.
