  • Patent number: 5718647
    Abstract: Replaceable blade and handle components are provided for a game stick. One of the components comprises a male element and the other comprises a socket element. The socket element has a cavity the surfaces of which can frictionally and releasably engage corresponding surfaces of the male element while leaving corner pocket(s) wherein facing surfaces are not in frictional contact. The present invention relates to game sticks, in particular to hockey sticks or the like, which comprise replaceable blade and handle components; such sticks include, for example, ice hockey sticks (including goalie sticks), street hockey sticks and the like. The present invention, by way of example only, will be described hereinafter in relation to an ice hockey stick.

  • Patent number: 4917105
    Abstract: This invention relates to a foot testing method to analyze the functional biomechanic type of the foot of a person such as an athlete to determine the appropriate insole to be fitted in the person's shoe as well as to a measuring device and insole used to implement this method. This method comprises the following steps: (1) placing the foot in a neutral (unloaded) position; (2) identifying the center line of the heel bone; (3) identifying the center line of the tendo Achillis; (4) placing the person tested in a standing position and preferably identifying the type of arch; (5) measuring the angle between the heel bone center line and the tendo Achillis center line preferably with his/her knees bent at approximately 45.degree..

  • Patent number: 4876807
    Abstract: A shoe, especially for use in athletic activities such as ball games, having a sole structure including a insole, a flexible midsole, and an outer sole forming a wearing surface. The outer sole in constructed, at least in a toe region of the shoe, in a cuplike form. An upper of the shoe is constructed, also at least in the toe region of the shoe, in a doubled manner, having an inner layer and an outer layer. The outer layer of the upper of the shoe and the outer sole are attached to the shoe, with an upwardly-rising, cuplike edge of the outer sole lying between the inner layer and the outer layer of the upper of the shoe. A method for manufacturing this shoe, and a blank for a sole of the shoe, are also provided by the invention herein.

  • Patent number: 4757620
    Abstract: A sole structure of a shoe, e.g. a sport shoe, comprising an outer wearing sole, an inner or intermediate layer, and additionally a cushioning and supporting structure between the sole and layer. The cushioning and supporting structure has a flexible toe portion extending substantially from a tip of the shoe to a ball area of a foot in the shoe, a resilient heel portion tapering in a wedge-like manner from a rear edge of the shoe towards the forward tip of the shoe, and extending at least over a heel area of the shoe, and additionally a body piece fitted above the heel portion and substantially extending from the rear edge of the shoe to the ball area of the foot, over a zone adapted to fit against the heel of the arch of the foot. The body piece is substantially stiffer and harder than the heel portion and the toe portion.

  • Patent number: 4595215
    Abstract: A running surface or coating material, or coating for a ski, for variable snow conditions, in particular for use in cross-country or long distance skiing, is mounted in the central region of the running surface of the ski as an ascending aid. The coating consists of a soft elastically behaving substance and a harder particle component. Part of the harder particles are so disposed that they project from the bottom surface of the ski. This is accomplished by grinding the surface of the ski bottom coating plate means to be the bottom surface, in such manner that a hairy cover is produced on the ground surface. The projecting particles of the hairy cover are affixed by their roots in the elastically behaving substance.

  • Patent number: 4259274
    Abstract: A ski which has a sandwich structure including upper and lower plastic laminations and a foamed plastic core situated therebetween with dense side portions integral with the upper and lower laminations and forming a shell surrounding the foamed core has in its new finished condition the same condition as when the ski is removed from a mold, so that finishing operations are not required subsequent to removal of the ski from the mold. The mold which is used to manufacture the ski has opposed relatively wide walls and a pair of opposed relatively narrow walls which are permanently fixed to one of the relatively wide walls while the other of the relatively wide walls is movable to and from an operating position closing the mold and cooperating with the relatively narrow walls for this purpose.

  • Patent number: 4059269
    Abstract: A stick to be used in ice hockey or the like, and in particular the blade structure thereof. The blade structure has a core consisting in its entirety of a single elongated body of wear-resistant material extending all the way from the bottom to the top edge regions as well as from the front tip to the rear end regions of the blade structure. This single core body has opposed side surfaces covered almost but not entirely by a pair of strengthening layers, preferably of reinforced plastic, while the core body itself is preferably made of wear-resistant plastic material. The core body projects downwardly beyond the strengthening layers as well as upwardly beyond the same to provide the blade structure with wear and impact-resistant elongated lower and upper edge regions formed by the core body itself. Preferably the core body also extends forwardly beyond the strengthening layers so as to be exposed and provide the blade with a wear and impact-resistant front tip region formed by the core body itself.

  • Patent number: 3982760
    Abstract: A stick to be used for ice hockey or the like. The stick is composed of a plurality of inner core pieces to the exterior of which reinforced plastic layers are laminated. Along the bottom of the blade of the stick is a hard-wearing core piece which extends downwardly beyond the layers laminated thereto so as to be exposed at the bottom edge of the blade for directly engaging the ice or the like. The several core pieces have only flat end surfaces engaging each other, so that they are not joined by tongue-and-groove joints or the like, and these core pieces may be held together at least temporarily by fasteners such as staples so that the assembled core pieces can then have the outer layers of reinforced plastic laminated thereto.
