ABSTRACT:
A jump skate comprises a boot with a base attachment, a surface engager, and a link/spring mechanism, which uses large spring deformation to boost a skater in jumping.
The link/spring mechanism comprises at least two links and at least one spring (coil or wound). The links and the spring(s) are made of metallic, synthetic, or composite materials.
The link/spring mechanism is connected to the boot and the surface engager with pin joints in such a way that allows large relative displacement with zero rotation between the boot and the surface engager, which offers improved control of the surface engager for skate jump/landing.
The spring(s) is installed in such a way that it deforms with relative displacements between the boot and the surface engager. Thus a skater can first store energy into the spring(s) by forcing the boot down towards the surface engager and then jump to release the energy for further height.
