Abstract: An in-line roller skate propulsion device comprising a lever and a wheel frame having a top, a bottom, a plurality of wheel axle holes near the bottom, a pivot connection near the top for pivotally connecting the lever to the wheel frame, and a hole and shaft combination for connecting a resilient member. The lever's pivot connection is located forward of the center of the lever. As the lever rotates around its pivotal connection to the wheel frame, the resilient member is stretched. Upon release of the rotating force, the resilient member returns the lever to a point of contact with the wheel frame or a stopping piece attached thereto. This action allows a skater to achieve greater speeds than with regular in-line roller skates while exerting the same amount of energy.

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.

Abstract: An in-line roller skate, which comprises a rigid shell wherein a flexible inner shoe is housed. The latter is advantageously lined at the level of its leg portion by a cover, thereby defining with it a sheath substantially open downward in which the upper part of the shell is housed. In this way, when the skater's ankle bends forwards it is supported by the inner shoe as a result of the interference arising between the cover and the upper part of the shell. This allows a great freedom of movement in a longitudinal direction for the skater's ankle, which can be bent even in a very accentuated manner, differently from what occurs in the known skates, where the bottom of the leg is enclosed in a rigid leg portion. At the same time, good support is maintained in a lateral direction owing to the upper part of the shell which allows the transmission of the guiding movements. According to a preferred embodiment, the cover may be hinged to the shell in the malleolar regions.
