Abstract
Abstract In a ski pole having a tubular rod it is proposed to make up the rod of a central metal tube and end portions of plastic having lower module of elasticity, heat conductivity and density. The metal rod terminates short of the disc and of the handle. The upper end portion is hollow and expands upward so as to form a hollow handle receiving the ends of the hand strap, one of which ends is adjustable. The lower end portion, which likewise is hollow, is shaped with abutments for the disc boss and is narrowed at the bottom so as to receive the spike.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
79 words
A ski pole comprising a rod having upper and lower end portions with hand strap and disc, wherein a substantial intermediate part of said rod comprises a tube of a material having a high modulus of elasticity, such as metal, at least one end of said rod comprising a portion of a lower modulus of elasticity, such as plastic, connected to the intermediate part at a location spaced from the adjacent one of the hand strap and the disc.
Claim 2
Dependent Claim
79 words
A ski pole comprising a rod having upper and lower end portions with hand strap and disc, wherein a substantial intermediate part of said rod comprises a tube of a material having a high modulus of elasticity, such as metal, at least one end of said rod comprising a portion of a lower modulus of elasticity, such as plastic, connected to the intermediate part at a location spaced from the adjacent one of the hand strap and the disc.
Claim 3
Dependent Claim
28 words
A ski pole as claimed in claim 1, wherein the end portion or portions of the rod are likewise tubular and mounted on the outside of the tube.
Claim 4
Dependent Claim
58 words
A ski pole as claimed in claim 1, wherein the lower end portion of the rod is hollow and consists of a material having a considerably lower density than the tube and is narrowed at its end so as to form an attachment for the spike and is molded with a shoulder forming an abutment for the disc.
Claim 5
Dependent Claim
38 words
A ski pole as claimed in claim 1, wherein the upper end portion of the rod consists of a material with a relatively low heat conductivity and is formed with a integral hollow handle portion with increased cross-section.
Claim 6
Dependent Claim
45 words
A ski pole as claimed in claim 4, wherein a portion of the hand strap extends into the handle portion through an opening in its side wall spaced from the terminal edge of the handle and has ends that terminate in the hollow space therein.
Claim 7
Dependent Claim
81 words
A ski pole as claimed in claim 5, wherein a knob is placed detachably in the free extremity of the handle portion and formed with two openings, and one of said strap ends extends from the opening in the side wall of the handle upwards through one and downwards through the other opening in the knob, and wherein said knob has an upward projection between said two openings, and the said strap end has adjustment holes for selectively engaging said projection.
Claim 8
Dependent Claim
41 words
A ski pole as claimed in claim 5, in which the other strap end is sufficiently thickened in its extremity for being locked within the handle by the insertion of the former strap end through the opening in said side wall.
