In the inventive ski stick, a profile wall (11) contains at least one longitudinally extending reinforcement element (13), which is at least partially embedded in the manufacturing step of the profile (10) in the wall structure (11) as an integral part thereof. The reinforcement element (13) may extend along the entire length of the reinforced-plastic profile or partially along its length, and its cross-sectional form may be circular or longitudinal or angular, e.g. triangular. ## Claims ### Claim 1 A ski stick comprising a hollow reinforced-plastic profile (10) having a profile wall (11) and at least one reinforcement element (13) extending in the longitudinal direction, said at least one reinforcement element (13) being at least partially embedded in the manufacturing step of the profile (10) in the profile wall (11) as an integral part thereof, said ski stick being manufactured by a pultrusion process in which the profile (10) is formed on top of said at least one reinforcement element (13). ### Claim 2 (depends on 1) A ski stick according to claim 1, comprising one reinforcement element (13) which extends partially or completely along the entire length of the stick (10). ### Claim 3 (depends on 1) A ski stick according to claim 1, comprising at least two reinforcement elements (13) which may each extend partially or completely along the entire length of the stick (10). ### Claim 4 (depends on 3) A ski stick according to claim 3, wherein the cross-section of the ski profile (10) is elliptic and said reinforcement elements (13) are placed on a longer axis line of the elliptical cross-section. ### Claim 5 (depends on 1) A ski stick according to claim 1, wherein said at least one reinforcement element (13) is hollow. ### Claim 6 (depends on 1) A ski stick according to claim 1, wherein said at least one reinforcement element (13) has a closed profile. ### Claim 7 (depends on 1) A ski stick according to claim 1, wherein said at least one reinforcement element (13) comprises a reinforced-plastic profile having a plastic portion and reinforcement fibers arranged therein. ### Claim 8 (depends on 1) A ski stick according to claim 1, wherein said at least one reinforcement element (13) comprises a material selected from the group consisting of metals, thermosetting and thermoplastic resins and wood. ### Claim 9 (depends on 7) A ski stick according to claim 7, wherein the plastic portion of the reinforced plastic comprises a material selected from the group consisting of nylon, polyesters, phenol resins, epoxy resins, vinyl ester resins, polycarbonates and polyolefines. ### Claim 10 (depends on 9) A ski stick according to claim 9, wherein the reinforcing fibers are selected from the group consisting of inorganic fibers, glass fibers, carbon fibers, boron fibers, ceramic fibers and metal fibers, and organic fibers, nylon, kevlar, polyester and polyolefine fibers. ### Claim 11 A ski stick comprising a hollow reinforced-plastic profile (10) having a profile wall (11) and at least one reinforcement element (13) extending in the longitudinal direction, said at least one reinforcement element (13) being at least partially embedded in the manufacturing step of the profile (10) in the profile wall (11) as an integral part thereof, said profile having an elliptic cross-section, said at least one reinforcement element being arranged on a longer axis line of the elliptical cross-section. ### Claim 12 (depends on 11) A ski stick according to claim 11, comprising one reinforcement element (13) which extends partially or completely along the entire length of the stick (10). ### Claim 13 (depends on 11) A ski stick according to claim 11, comprising at least two reinforcement elements (13) which extends partially or completely along the entire length of the stick (10). ### Claim 14 (depends on 11) A ski stick according to claim 11, wherein said at least one reinforcement element (13) is hollow. ### Claim 15 (depends on 11) A ski stick according to claim 11, wherein said at least one reinforcement element (13) has a closed profile. ### Claim 16 (depends on 11) A ski stick according to claim 11, wherein said reinforcement element (13) comprises a reinforced plastic profile having a plastic portion and reinforcement fibers. ### Claim 17 (depends on 11) A ski stick according to claim 11, wherein said reinforcement element (13) comprises a material selected from the group consisting of metals, thermosetting resins, thermoplastic resins and wood. ### Claim 18 (depends on 16) A ski stick according to claim 16, wherein the plastic portion comprises a material selected from the group consisting of nylon, polyesters, phenol resins, epoxy resins, vinyl ester resins, polycarbonates and polyolefines. ### Claim 19 (depends on 18) A ski stick according to claim 18, wherein the reinforcing fibers are selected from the group consisting of inorganic fibers, glass fibers, carbon fibers, boron fibers, ceramic fibers, metal fibers, organic fibers, as nylon, kevlar, polyester and polyolefine fibers.
