Abstract
Abstract Skate comprises a shoe portion (1) a ground touching device (11) and a transition portion (3) which connects the ground touching device (11) to the shoe portion (1). The shoe portion (1) and the transition portion (3) are made in one piece and form a shell of a sandwich construction with a core (5) made of foam plastic and outer layers (6,7) made of plastic reinforced with glass or carbon fibers. The ground touching device (11) may be a metal section fastened by glue in a downwards opening groove (1) formed in the transition portion (3) and adapted to glide on ice or rollers arranged in the groove and adapted to rotate about respective shafts fastened to the transition portion. There is thus provided a very light skate which renders good support to the foot and has little air resistance.

Claim 1
Independent Claim
224 words
In a skate having a shoe portion, a ground touching portion and a transition portion connecting the shoe portion to the ground touching portion, the shoe and transition portion being of one piece construction, the improvement comprising: walls having inner and outer sides in the shoe portion adapted to enclose a wearers' foot; walls having inner and outer sides forming the transition portion; said walls being integrated as a unitary shell having a sandwich construction comprising a core of foam plastic, outer layers of plastic material attached to the inner and outer sides of said walls, and fiber reinforcing in said outer layers; said transition portion having a substantially V-shaped cross-sectional configuration having an upper part joining said shoe portion and a lower part; a sole means within said shell between and connected to said walls thereof; said outer layer on the outer sides of said wall extending continuously from the upper part of said shoe portion to the lower part of said transition portion and said outer layer on the inner sides of said walls extending continuously from the upper part of said shoe portion to a level below said sole means; a groove in the outer surface of said lower part of said transition portion extending in the longitudinal direction of the skate; and a ground engaging means mounted in said groove.
