Abstract: A rigid reinforcement member extends longitudinally along the neck portion of the skate blade holder, to reduce stress and improve force transfer. The blade holder has a longitudinal slot running along the bottom thereof to receive a blade or runner, which is secured in the slot. At least one rigid reinforcement member runs along at last the neck portion, within the slot and above the runner, the slot being enlarged at the location of the reinforcement member(s) in order to accommodate the member(s). Preferably, the reinforcement member is in one piece, including an upper web portion and an integral channel with a cross section in the form of inverted U-shape beneath the upper web portion. The arms of U-shape run alongside the runner, one on either side of the runner, and the base of the U-shape lies against the top of the runner and follows the shape thereof. Preferably, the rigid reinforcement member is of a reinforced plastic composite material, although a metal could also be used.

Abstract: A braking system for an in-line skate, where a linkage assembly connects a rotatable boot cuff to a brake assembly which pivots between a retracted position braking position. The linkage assembly includes a drive arm, a transfer bracket and a short connector link. The transfer bracket has three pivot points which are arranged such that the mechanical advantage provided by the transfer bracket in translating downward movement of the drive arm to downward movement of the connector link and brake assembly is less than one in the retracted position, and increases as the cuff is rotated rearwardly to move the drive arm downwardly and the brake assembly towards the ground. Preferably, the connector link rotates over center to a locked position once the brake is in contact with the ground and the cuff is rotated slightly rearwardly.

The molded plastics support includes a boot receiving means having the outline of the sole of the boot and having a ridge adapted to be fixed to the base of the boot. The support may be fixed to the boot by way of a suitable adhesive, and the boot receiving portion of the support replaces the sole of the boot.

Abstract: The ski boot comprises a quarter formed of two complementary parts which partly overlap each other when closed along two vertically extending lateral centerlines. The rear part of the quarter is pivoted to the boot shell, and the quarter front part may be pivoted to the rear part, being guided by a cam arranged to slide over a stud which is rigidly attached to the shell and may be rotatably adjusted, the rotation of the rear part of the quarter, additionally to closing onto the front part, also moving a cuff-line member which closes the skier's foot instep.

Abstract: The device comprises hollow frusto-conical elements adapted for enveloping a ski boot inner shoe and/or in combination also a ski boot shell. The frusto-conical elements are adapted to be pulled toward the rear portion of a boot. To this end, each frusto-conical element is associated with a small adjustable length cable by means of devices positionable externally on a bootshell, which devices are adapted to place the small cables themselves under tension.

Abstract: A sole construction for protective shoes comprises a protective mid-sole and an integrally molded insole and heel plug, the plug portion including a top surface, a recessed bed in the top surface, spaced-apart anchoring projections in the recessed bed and a slot extending through the insole laterally thereof adjacent the plug and communicating with the recessed bed. The mid-sole being coextensive with the insole and including a rearward extension adapted to pass through the slot in the insole and be received in the recessed bed. The rearward extension of the mid-sole includes complementary anchoring seats adapted to be selectively engaged by at least one of the anchoring projections in the bed.

Abstract: A fastening and locking device structure, particularly for ski boots, comprises a hollow frusto-conical element enclosing the ski boot shell at a middle region thereof. The frusto-conical element extends at a top region into a tongue and laterally to the ski boot into two wings encircling the ski boot middle region and joining together in a groove provided between the sole and the heel region of the ski boot. The frusto-conical element is further fixedly connected with two lugs extending towards the boot heel, whereat they present a tension lever device for fastening them together and tightening the boot flaps.

Abstract: A ski boot is described in which the body of the boot may be moved in a crosswise direction in relation to the sole, in such a way that it may be correctly aligned with respect to the ski. More particularly, the sole has at least one of its ends, the toe or the heel, joined to the body in a gliding manner, by means of an essentially prismatic connection (dovetail). In that way, the body of the boot may be fixed on a ski in the position that is morphologically most suitable for the skier.

Abstract: A hinged sport boot having an upper boot portion with hinge openings in its sides and a lower boot portion with integral, headed, hinge pins projecting from its sides. The heads of hinge pins are slightly larger in size than the openings so that the pins must be forced through the openings to hingedly connect the upper and lower portions together. A locating depression is provided on the central outer surface of the head of each pin to properly locate a connecting tool used to connect the boot portions together. The invention is also directed toward a method for connecting the boot portions together.
