DESCRIPTION AND FEATURES OF THE ALLFLEX ANTI-VIBRATION PLATE
Allflex anti-vibration plates are intended for skiers and snowboarders. Skiing and snowboarding with the Allflex plate is much easier; the ski/snowboard goes into the turn much more easily than with any other plate.
The grip is significantly better compared to other plates. The skier/snowboarder doesn't feel the vibrations during the turn because the plate isn't directly fastened into the ski/snowboard. The snowboard plate is attached to the snowboard with four vertical and four horizontal rocker arms, which mutually cancel out vibrations.
There are two basic variants of the Allflex plate, both for skiers and snowboarders:
1. Plate for recreational skiers/snowboarders is neutral and cancels out all vibrations.
2. Plate for racers accelerates when coming out of a turn, in addition to the above features.
MORE ABOUT THE ALLFLEX PLATE
1. The Allflex plate allows independent and unobstructed bending of the ski or the snowboard as well as a complete grip of the edge carved into the snow. The ski or snowboard bends in one arch due to the floating mounting of the plate.
2. The Allflex system is based on two rigidly anchored vertical rocker arms at the front and two rockers arms at the back as well as two horizontal rocker arms in the middle of the plate.
3. Vertical rocker arms at the front and at the back function as compensatory parts, cancelling the shortening of the ski's upper surface due to bending.
4. Vertical rocker arms at the front are constructed in a way that the part of the plate onto which the binding is mounted is anchored under the rigid part of the rocker arm. This cancels the impact of the wedge principle.
5. Because the pivot of rocker arm anchorage is under the pivot of the rigid part of the plate, the vibrations from the ski are not transferred to the skier's skeleton; instead, they are canceled by the suspension of the bent ski into a horizontal movement of rigid parts of the plate, which are screwed onto the ski or snowboard.
6. The upper double rigid part and the lower double rocking part of the rocker arm are mutually connected with a connector. Both parts allow for complete rigidity of the rocker arm, and at the same time they reduce traction between moving parts to the minimum.
7. At the same time as the vertical rocker arms at the front and the back, the two double horizontal rocker arms in the middle of the Allflex system function synchronously, keeping the loaded ski binding springs in balance and controlling the bending of the snowboard.
8. The bottom dead center of the moving part of the horizontal rocker arm is under the horizontal axis of the rigid part of the horizontal rocker arm.
9. The amplitude of movement of the horizontal rocker arms depends on the bending of the ski or snowboard.
10. The bottom dead center of the horizontal rocker arms movement is always at the same level.
11. The horizontal line of the axis of the horizontal rocker arms causes the ski bindings to load by 0.07 mm; all other positions of the horizontal rocker arms keep the springs in the bindings at a neutral spacing. The vertical rocker arms at the front allow for horizontal oscillation of rigid parts of the Allflex system by 4.5 mm at the front and 4.5 mm at the back. The spacing between bindings on rigid plates by other manufacturers increases by 2x4.5 mm, which means the bindings need to be tightened considerably, in turn increasing the risk of injury because the bindings do not open in case of the skier falling.
12. Horizontal rocker arms allow completely evenly distributed pressure along the edge, making the skier's or snowboarder's weight evenly distributed along the edge from the tip to the tail, regardless of the balance. The edge adapting to the terrain along its length makes it easier to keep the center of gravity balanced.
13. The maximal vertical movement of horizontal rocker arms is 6.4 mm. Full pressure increases the distance between the ski boot sole and the edge by 6.4 mm at the most.
14. The Allflex system allows for a complete grip of the edge, despite the distance between the ski boot sole and the bottom ski or snowboard surface oscillating between 0 and 6.4 mm, and at the same time, it cancels vibrations in the curve or due to an uneven terrain.
15. The Allflex system for skis allows for shoe sizes of 36–46. For smaller shoe sizes the plate needs to be shortened.
16. The Allflex plate is ideal for hard or icy slopes. Compared to other plates, it reduces vibrations at least by half, which makes it suitable for all categories of skiers and snowboarders, especially children.
17. Vibrations that are always present on hard slopes are significantly less intense and noticeable, while the pressure on the edge is softer.
18. Using the Allflex plate the skier or snowboarder only needs to control the tension of the bent ski or snowboard. All other plates require the skier or snowboarder to control the bending of the ski or snowboard along with the plate up until the pressure release; in addition, the skier also has to control the springs in the bindings, which load in proportion to the bent ski because of the circular segment.
19. The Allflex plate significantly reduces the risk of injury as a result of vibrations and lateral pressure on knees and shins; firstly, because there are fewer vibrations, and secondly, the vibrations are softer due to the floating plate and the skier or snowboarder hardly feels them.
20. The Allflex plate solves all problems with injuries for skiers that are results of bindings adjusted too tightly, which is necessary with other plates as the ski bends under the ski boot along with the plate when pressure is applied. The Allflex plate, on the other hand, does not bend and allows for free bending of the ski while the bindings don't have to be adjusted more tightly.
