Abstract
The invention provides ice skates and methods of making ice skates which have a body of a synthetic plastic material and a steel blade. The body includes an upper portion for attachment to the sole of a suitable boot and the blade has an upper portion enclosed in the body and a lower portion projecting from the body. The blade has a non-interfering upper surface which allows the body to move freely longitudinally of the blade during shrinking. This movement prevents build-up of residual stress in the body.
Claims13
A method of forming an ice skate assembly of the type including an elongated steel blade having an upper portion, a lower portion including a skating edge, and ends, and a blade-supporting body of a synthetic plastic material and comprising the steps:
- forming a plurality of transverse holes in longitudinal alignment along the length of said blade;
- heat treating to harden said blade;
- temporarily plugging the transverse holes in said blade;
- moulding a blade-supporting body of synthetic plastic material about said upper portion of the blade including said holes such that at least one of said ends of the blade is not covered by the blade-supporting body;
- allowing said body and blade to cool after moulding whereby said plastic body may shrink relative to said blade;
- unplugging the blade holes so as to provide transverse passages through said body and said blade;
- and
- inserting means in said transverse passages to mechanically interlock said blade and said body.
A method of forming a skate assembly of the type including an elongated steel blade having an upper portion, a lower portion including a skating edge, and ends, and a blade-supporting body of synthetic plastic material comprising the steps:
- forming a plurality of transverse holes in longitudinal alignment along the length of said blade;
- heat treating to harden said blade;
- filling said blade holes with a material softer than said hardened steel blade;
- moulding a blade-supporting body of synthetic plastic material about said upper portion of the blade including said filled holes such that the lower portion and at least one of said ends of the blade are not covered by the blade-supporting body;
- allowing said moulded plastic body and said blade to cool whereby said body may shrink without interference by said blade;
- removing said material from said blade holes so as to provide transversely open passages through said body and said blade;
- and
- inserting means in said transverse passages to mechanically interlock said blade and said body.
A method of manufacturing an ice skate of the type which is to be attached to the sole of a suitable boot, the method comprising the steps:
- forming an elongated steel blade having an upper portion including a non-interfering upper surface and non-interfering side surfaces, a lower portion including a lower ice engaging surface terminating in upwardly curved front and rear end portions, and ends;
- moulding a blade-supporting body of synthetic plastic material about the upper portion while leaving the lower portion unenclosed and such that the blade-supporting body is in contact with said upper surface and said side surfaces and such that at least one of said ends of the blade is not covered by the blade-supporting body;
- allowing the moulded body to cool whereby the body may shrink longitudinally of the blade without interference with the blade;
- and
- inserting fastener means through the assembly of the body and the blade at said upper portion to mechanically lock the blade and the body to one another.
