Summary
A binding for snowboards that is rotatable in a free angle range
The present invention relates to a binding for snowboards , which is rotatable in a free range of angles (11,12) while snowboarding .
To drive in the direction on the ski-lift, the binding can be put at the leading foot in a self-locked position (10) .
The binding consists of a rotatably mounted binding plate (2) , which is held by a fastening plate ( 1) and a radial spacer. Here, a mandrel (5) between two limiting elements (6,7) is moved. A spring element (8 ) allows automatic tightening and loosening for lift rides .
This binding can drive much easier curves and easy to drive in 2 board directions. This binding also reduces the mechanical stress on the feet . By limiting the angle ensures that the foot can not turn too far and that the board itself does not deviate , if only one leg is in the binding. For riding with the ski lift, the binding can be put into the driving direction.

A binding for snowboards that is rotatable in a free angle range while snowbarding
DEscriptION
Die vorliegende Erfindung beschreibt eine Bindung für Snowboards, die während der Abfahrt in einem freien Winkelbereich (11,12) drehbar bleibt.
Zum Fahren in Fahrtrichtung am Ski-Lift kann die Bindung am führenden Fuß in eine selbst-feststellende Position (10) gestellt werden.
The present invention relates to a binding for snowboards , which is rotatable during the snowboarding in a free range of angles (11,12) .
To drive in the direction on the ski-lift, the binding can be put at the leading foot in a self-locking position (10) .
The binding consists of a rotatably mounted binding plate (2), which is held by a fastening plate (1) and a radial spacer. Here, a mandrel (5) between two limiting elements (6,7) is moved.
The binding of the leading foot is extended in the way, so that an automatic or manual element fixes the position in the traveling direction and released again.
With this binding you can drive much easier curves, easily drive small rotations and ride in 2 board directions. This binding also reduces the mechanical stress on the feet. By limiting the angle ensures that the foot can not turn too far and that the board itself does not deviate, if only one leg is in the binding. For ride on the ski lift, the binding can be put into the driving direction.
CONDITION
Snowboard Bindings are designed so that you can bind the snowboard boots to a bracket which is fixed to the snowboard. The holder is fixed firmly at an angle while driving.
Derived therefrom , there are a number of systems that allow to turn the binding in a fixed angle prior to the journey.
This is especially the binding of Emery / Rosignol ( EP19980946647 ) , which fixes a small lever with a mounting plate to an inner ring gear below the mounting plate. All known systems are interpreted to set a fixed angular position while driving. A freely rotatable system is shown in ( EP 1741474 B1) , in which a rotatable disk with a raised portion between the two plates is mounted . Here, the rotating part is completely between two plates
The disadvantage of fixed- oriented bindings is that you can only walk badly with one foot strapped. In addition, the leg is often not perfectly aligned when turning in the downhill . This can be very problematic especially at tumbles, since the forces acting transversely to the knee joint . Experiments have shown us that you are much freer riding with a snowboard , if you use any determination of the angle.
During the driving it is obtained caused by the characteristics of the drivers body, that a freely rotatable binding rotates only in an range of angle of about 90 degrees (11,12) .
Unfortunately, with freely rotatable snowboard bindings with an angle of 360 degrees is not possible to drive with one leg when being dragged by a lift, as the board rotates away to the sides. In addition, the board slips when stepping on slopes always on the free side away . One-legged sliding when getting out of chair lifts are also hardly possible since the board rotates away .
TASK
The invention is intended to have the properties of a rotatable binding when snowboarding, but at the same time, the binding may not slide away when one-legged usage. When lift driving a one-legged ride should be possible.
SOLUTION
A rotatable binding is created from a binding plate ( 2) which rotates with a precisely shaped radial hole by a radial spacer ( 3). At the binding plate , the binding elements , belts, step-in gears are fixed. To the top the binding plate is held by a mounting plate ( 1). The mounting plate is located in a deepening ( 21) of the binding plate . Since the spacer ( 3) is a little higher than the binding plate , there is a small free distance (D) , which makes it possible that the binding plate can rotate freely , although the binding on the snowboard (20 ) is tight mounted .
In studies during the ride of freely rotatable bindings it has been shown that only a free angle range of approximately 90 degrees is used in spite of the free rotation (12).
In ( Fig. 3) the used free-angles (11 +12 ) are shown that are used from the feet while driving. Normally you take the leading foot slightly in the direction that calls itself Regular . Some people like to drive with the right foot forward, which is known as Goofy, in which case the feet are oriented to the right.
Both times it is used the free angle range. With a completely free rotatable binding arise during the ride very often rapid rotations that lead to reversing what is called fakie . But by the rotatable binding rotate the feet automatically in the direction of travel , what corresponds to quasi a fakie to goofy . Thus only 90 degrees are used .
If you drive but with the lift, then the leading foot must be turned toward board tip and the rear foot is placed on the board.
(FIG. 4) For a solution of the free angle (12) during the journey
in the rear binding two bounding elements (6.7) at an angle of approximately 90 degrees to the rotating binding plate have to be placed.
A mandrel (5) on the fixed mounting plate prevents the rotating binding plate at further rotation and thus becomes an end stop of the clockwise rotation and counterclockwise rotation.
For the binding at the front foot a larger angle must be enabled. For this, the bindig must, in addition to free angle (11) also be rotated in the angle range (10).
Since the feet during a normal driving not exceed the angular range (11), no additional barrier must be installed. Only in case of accidents, the angle is exceeded. This crossing is even meaningful.
(Fig. 5) In order to use the extended area (11 +10), the execution takes place as follows:
The boundary element (7) in so far positioned at an angle to the right until the fixed mandrel (5) comes to a stop when rotating of the binding plate in the driving direction . A movable spring element (8) on the binding plate slides over the mandrel (5) in rotation and locked then by its shape, by the elevation of the crossed over element.
(FIG. 6), the spring element (8) can also be extended with a manual locking and unlocking. The spring can be biased by a small screw (15) to adjust the engagement and release of force.
An additional manual element (14) may also lock or unlock the mandrel . For this purpose, several embodiments are possible.
The crossed over spring can be designed as a leaf spring, so that the binding plate is braked when it rotate in the locking zone (10). This additionally avoids unintensional locking during normal driving.
(Fig. 7) A possible change in the design can be formed in such a way that instead of individual barrier elements with complex-shaped discs adapted form be used.
(Fig. 8)Further it may be possible to move the locking elements in the region of the radial spacer or even between the binding plate and a fixed washer (4).
The detected free angular range of 90 degrees is first determined empirically.
However, to enable adjustments in the size of the angular range the boundary elements (6,7) may be designed also adjustable. This can be configured via screw, plug or sliding positions.
