Energy storing spring from wood

摘要

The invention relates to energy storing wood springs having the shape of a cylindrical compression spiral spring, a conical compression spiral spring, a double-cone compression spiral spring, a square-section compression or tension spring, a spiral flat spring, a coil-spring of cylindrical outer shape, a wave spring, or a layered flat spring, or possibly a tension, compression or torsion spring characterized by an arbitrary space curve. The essence of the invention is that, with spring geometries similar to those of metal springs, wood is also capable of performing energy storing and energy-releasing operations, especially when the material of the wood spring is compressed wood.
