Patent number: 6939257Abstract: A method for manufacturing a shaft of an ice hockey stick, or the like, and a shaft. The shaft comprises an inner, first body part formed of binding material and reinforcing fibers that cross one another. Onto the first body part there is formed a second, substantially co-axial, body part containing binding material and longitudinal reinforcing fibers. The cross-section of the inner profile of the first body part is oval and the cross-section of the outer profile of the second body part is substantially rectangular, the shaft being thus provided with wall thickness that is greater at the corners than at the sides.Type: GrantFiled: June 19, 2002Date of Patent: September 6, 2005Assignee: Montreal Sports OyInventor: Antti-Jussi Tiitola

Publication number: 20040229720Abstract: A composite hockey stick having a tubular hollow rectangular shaft and a blade is disclosed. The shaft comprises an inner layer and an outer layer, each of the inner and outer layers are formed of uni-directional substantially continuous fibers disposed in a hardened resin matrix and wrapped and molded around a middle elastomer layer. A new manufacturing method is also disclosed in which a cured hollow tubular composite hockey stick shaft is inserted between the front and back faces of an un-cured composite hockey stick blade and the blade is then cured in a mold around the hockey stick shaft to form a unitary composite hockey stick.Type: ApplicationFiled: October 20, 2003Publication date: November 18, 2004Applicant: Jas.
