Abstract: A sport ball is provided with an outer ball surface which has portions having a roughness higher than the portions of the surface. These rougher portions are obtained by applying, using a serigraphic process, a coating composition comprising a binder and an inorganic builder, the latter advantageously including a combination of substances having hydrophilic and hydrophobic properties.

Abstract: A high-top athletic or leisure shoe is provided, in which the top portion of the shoe leg is made of padded material which includes a piece of reinforcing material on the outer surface of the shoe at substantially the height of the outer malleolus. At least one two-segment tightening strip is provided extending from the reinforced zone. One segment of the tightening strip rises diagonally from the reinforced zone along the outer surface of the shoe leg to near the upper end of the latter at the back of the shoe, and continues substantially horizontally along the upper end of the inner surface of the shoe leg above the inner malleolus. A second segment rises diagonally from the reinforced zone, and extends across the frontal lacing area of the shoe toward the inner surface of the shoe leg. A provision is made for joining the two segments of the strip over the front and inner surface of the shoe leg so as to adjustably fasten the strip in position with a desired degree of tightness.

Abstract: A ski binding for a touring or cross country ski in which a front extension of the sole of the boot enters a region in an archplate of the same size as the extension. The archplate is fixed to the ski and a fastening element holds the extension in the archplate. The extension has beveled edges and a reduced thickness area to enhance flexing at a location between the boot tip and the archplate engaging part of the extension.

Abstract: A ski binding in which a locking bar is rotatable between a locked and unlocked condition of the binding. In the unlocked condition the extension of the sole of a ski boot can be inserted into an archplate of the same height and width as the extension, with the bar passing through an inlet of extension to a position within an opening which is larger than the inlet. Angular movement of the bar to the locked position prevents withdrawal of the extension from the archplate.

Abstract: A one-piece woman's competition swimming suit has a continuous elastic edging, made in a single piece, forming a closed loop around the openings for the passage of the legs in the lower portion of the suit, rising at a slant along the lateral sides of the suit, then forming the lower peripheral edging of the upper portion of the suit, and joined to a transverse edging of the upper portion of the back of the suit essentially in a central region thereof in which two back straps converge, and are also connected to the transverse edging. The transverse edging can form a continuation of the armpit edging of a breast panel of the suit.

Abstract: A ski binding for a cross country or touring ski. The binding has an archplate to receive an integral forward extension of the sole of the ski boot, and a crossbar engages behind a shoulder on the extension to fasten the boot to the ski. The crossbar forms an upper transverse portion of the archplate and also fastens the extension of the boot in the binding.

Abstract: A ski binding with a toe iron which supports an essentially U-shaped bowed metal rod, whose middle section is pivotably attached to the front end of the toe iron. The backwardly-extending legs of the U-shaped rod are bent at an approximately right angle down toward the ski. The legs of the U are arranged so as to be freely movable in the horizontal direction against the legs' spring force out toward the ears of the toe iron. In cooperation with a boot sole which has notches cut into both side edges, the binding will be made to fasten when the boot is inserted with a degree of pressure in between the ears of the toe piece.

Abstract: An elastic sport shoe sole having a plurality of parallel ribs, and each rib is provided on its length alternate zones of different types, one type is a downwardly rounded section of which the width is substantially each to the height and the other type is a narrow section in the form of a lamellar of which the width is small with respect to the height.
