Abstract: An in-line roller skate assembly having at least three running rollers that are substantially equal in diameter and disposed one behind the other in a running direction of the skate assembly. Each running roller has a convex shaped rolling surface with a pair of laterally spaced curved shoulder portions having a common radius of curvature as defined in a plane intersecting a rotational axis of the respective roller. The radius of curvature of the curved shoulder portions of the front and rear rollers are greater than a radius of curvature of each curved shoulder portion of the intermediate roller or rollers.

Abstract: An ice-skate having a high shoe upper part, in particular in the area of sport, requires an increased spatial requirement for the ankle in the event of a pronounced forwards inclined movement. Therefore, it is recommended to form the closure edges in the upper shaft region so as to protrude in a convex manner in the direction of the foot middle plane, in order to increase the size of the surface and to place forward the closure parts in order to change the pulling effect thereof. Furthermore, lining or padding can be provided in the region of the extensions.

Abstract: The ski boot comprises a shell upon a sole. The shell comprises a back heel portion, a shell tip and a front portion rearwardly extending from the shell tip to approximately an instep region. The front portion also has a longitudinal slot to divide part of the front portion into two shell flaps. A rear flap is pivotably mounted to the heel portion and a cuff is pivotably mounted to the shell portion, both the rear flap and cuff being capable of forward and backward movement. Structure is provided for closing the cuff in separable connection with the rear flap such that the cuff and rear flap when closed define at least part of a tubular shaft for a skiers leg. An outer wall above and at the sides of the front portion of the shell forms at least one chamber substantially sealed toward the outer surface of the outer wall and defined by the front portion at the bottom. The length of the outer wall is changeable depending on the pivotal movement of the cuff.

Abstract: The cross-country ski boot (1) has protrusions (4) extending laterally downward over its sole (3), the clear width between said protrusions essentially corresponding to the width of the ski (2) so that the ski (2) is in its operating position embraced by the sole of the boot (1). The cross-country ski boot (1) is secured against being shifted in the longitudinal direction (5) of the ski (2) by a swingable locking member (17) which, when swung in a position pointing to the ski tip, releases the sole protrusion (12) of the cross-country ski boot (1) and, upon having been swung into the operating position, fastens the sole protrusion to the surface of the ski. Thus one single swingable locking element suffices to secure the cross-country ski boot (1) in its position. The boot (1) is laterally guided on the ski (2) by the lateral protrusions (4) of the sole (3). (FIG. 1).

Abstract: A structure for a use in either an anti-crossing device for skis or a ski brake. A torsion spring is utilized to urge a projection member to an upright position on the ski. In the anti-crossing device for skis, the resilient projection member will prevent movement of a ski to the crossed position in one direction while simultaneously permitting movement of the ski in the opposite direction by flexing the resilient projection downwardly onto the upper surface of the ski. In the ski brake environment, the ski boot effects a resilient flexing of the projection member down onto the upper surface of the ski when the ski boot is mounted between the ski bindings. The resilient projection member has extension members which project below the lower surface of the ski when the resilient projection member is in the upright position.

Abstract: An improvement in a ski binding arrangement wherein a ski boot is secured to a sole plate which in turn is releasably secured to a ski. The ski boot is pivotally secured by a front support to the sole plate and the heel of the ski boot is releasably secured to the sole plate. The ski boot is comprised of two parts, an upper leg part which is pivotally secured about a horizontal axis relative to the lower boot part. The heel holding assembly serves to lock the upper part of the ski boot to the lower part of the ski boot when the skier is using the ski boot in a downhill skiing environment. A movement of the heel holding assembly to a non-use or cross-country skiing position will facilitate a relative movement between the upper leg portion of the ski boot and the lower boot part.

The part of the binding in the recess cooperates as desired with the other binding part which latter is fixed to the ski. In this invention the recess is transverse of the boot and open at both ends. The boot sole may be longitudinally curved on the bottom thereof to facilitate walking. Ribs may be provided within the recess to urge snow and ice outwardly through its open ends as such snow and ice is packed thereinto.

Abstract: Safety release ski binding. There is here disclosed a release binding for skis in which the force required to effect a release is modulated in response to the relative angular position of the leg of the skier with respect to the longitudinal line of the ski. In the several embodiments shown, a resiliently backed device is provided in the usual manner for releasably holding a ski boot onto a ski, such device effecting release when a predetermined stress is applied for moving the ski boot relative to the ski. A further device is affixed either directly to the leg of the skier or to the upper part of the boot for detecting a longitudinal angular movement of the skier's leg with respect to the ski which device then diminish from a central position, corresponding to a central angular position of the skier's foot or leg, the tension on the above-mentioned resilient holding device. Thus, in a central position, the force required for release is at maximum.
