Springboard family with composite spring system and adjustable spring characteristics

Abstract

Springboard with rod spring system made of fiber-reinforced plastic (composite material) Springboard for artistic gymnastics with a spring system made of fiber-reinforced plastic, which, in contrast to conventional wooden or metal springs, offers an improved combination of weight savings, elasticity and energy transfer.

Claims

[1] Springboard with rod spring system made of fiber-reinforced plastic (composite material) Springboard for artistic gymnastics with a spring system made of fiber-reinforced plastic, which, in contrast to conventional wooden or metal springs, offers an improved combination of weight saving, elasticity and energy transfer. [2] Adjustable hardness and rebound properties through (rotary) sliding mechanism Mechanism for adjusting the spring characteristics by introducing buffer elements in the spring travel, whereby the spring travel, the spring hardness, the energy absorption of the spring and ultimately the energy release (rebound behavior) of the springboard can be varied without complex and dangerous spring replacement. [3] Optimized force-displacement curve for joint-friendly energy return. Progressive spring behavior that avoids force peaks, ensures a uniform energy return and prevents unwanted counter-strikes through integrated buffer elements. [4] Early response to low weight force for beginners and children. Design that allows a noticeable deflection of the top board even at low loads to enable beginners to use it intuitively and learn faster. [5] Constant spring stiffness Due to the coordinated combination of spring system and stability of the upper and lower boards, a largely constant spring stiffness is achieved on the upper two thirds of the take-off area, so that the jump quality depends less on the exact take-off point. [6] Body mass-dependent adjustment for different user classes Modular springboard system with spring characteristics that can be adjusted to different body masses for consistently optimized performance across different performance levels of the athletes.
