Abstract
Abstract A flagpole, particularly for indicating goals in skiing competitions, comprising an upper flag carrying portion and a lower pointed portion connected by a helical spring. When this flagpole is driven into the ground, it can move elastically laterally when hit by a skier, thus avoiding to be knocked down or causing injuries to the skier. Preferably the flagpole is provided with a semi-cylindrical abutment shell on one side so that it can move only to the other side, with a telescoping sleeve in its lower pointed portion for adjusting its length, and anvils adapted to be struck with a hammer for driving it down into the ground or hard snow.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
A flagpole, for indicating goals in skiing competitions, comprising an upper flag carrying portion and a lower pointed portion for insertion in the ground, a helical spring rigidly secured at its ends to said upper and lower portions of said flagpole in coaxial relationship therewith, a semicylindrical shell embracing substantially half of the periphery of the helical spring and extending over its entire length arranged on one side of said helical spring to form an abuttment for said upper portion, a bushing integral with said shell embracing said lower pointed portion, said bushing having a snug frictional fit permitting said abutment to be angularly rotated relative to said lower pointed portion.
Claim 2
Dependent Claim
111 words
A flagpole, for indicating goals in skiing competitions, comprising an upper flag carrying portion and a lower pointed portion for insertion in the ground, a helical spring rigidly secured at its ends to said upper and lower portions of said flagpole in coaxial relationship therewith, a semicylindrical shell embracing substantially half of the periphery of the helical spring and extending over its entire length arranged on one side of said helical spring to form an abuttment for said upper portion, a bushing integral with said shell embracing said lower pointed portion, said bushing having a snug frictional fit permitting said abutment to be angularly rotated relative to said lower pointed portion.
Claim 3
Dependent Claim
56 words
A flagpole as claimed in claim 1, wherein said lower pointed portion of said flagpole is formed of two members, an upper tubular member and a lower pointed stem member mounted for sliding movement within the upper tubular member and provided with means for locking it in different vertical positions with respect to said tubular member.
Claim 4
Dependent Claim
58 words
A flagpole as claimed in claim 2, wherein said locking means comprises a vertical longitudinal slot located in said upper tubular member and having at least two transverse horizontal branches, and a pin extending perpendicularly from the periphery of said pointed stem member and rigidly mounted thereon for longitudinal sliding movement in and along said vertical longitudinal slot.
Claim 5
Dependent Claim
23 words
A flagpole as claimed in claim 3, wherein a battery-powered lamp with associated switch is mounted at the upper end of said flagpole.
