Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
142 words
A pair of ski poles, each comprising a pole member having a hand-engaging end and a ground-engaging end, a disk having a peripheral edge, mounted on said pole member adjacent to the ground-engaging end such that a tip of the pole extends beyond said disk, for engaging the ground; scraper means on said disk for cleaning ski boot soles and other flat objects, and means on said periphery of said disk for coupling the disk with a disk of the other of said pair of ski poles to form an assembly having said poles spaced from one another, said scraper means of each disk being located proximate said coupling means and between the poles when the disks are coupled, thus providing a firm frame enabling support of a skier while the boot of the skier can be cleaned on said scraper means.
Claim 2
Dependent Claim
142 words
A pair of ski poles, each comprising a pole member having a hand-engaging end and a ground-engaging end, a disk having a peripheral edge, mounted on said pole member adjacent to the ground-engaging end such that a tip of the pole extends beyond said disk, for engaging the ground; scraper means on said disk for cleaning ski boot soles and other flat objects, and means on said periphery of said disk for coupling the disk with a disk of the other of said pair of ski poles to form an assembly having said poles spaced from one another, said scraper means of each disk being located proximate said coupling means and between the poles when the disks are coupled, thus providing a firm frame enabling support of a skier while the boot of the skier can be cleaned on said scraper means.
Claim 3
Dependent Claim
36 words
A ski pole as claimed in claim 1 wherein the coupling means comprises an extension and an adjacent slot on said disk, the extension of one disk being fittable with the slot of the other disk.
Claim 4
Dependent Claim
31 words
A ski pole as claimed in claim 1 wherein said disk has a tear-drop shape in plan view forming narrow and wide ends, the coupling means being at said narrow end.
Claim 5
Dependent Claim
16 words
A ski pole as claimed in claim 3 wherein said disk further includes radial reinforcing webs.
Claim 6
Dependent Claim
17 words
A ski pole as claimed in claim 3 wherein said disk is composed of a plastic material.
Claim 7
Dependent Claim
25 words
A ski pole as claimed in claim 3 wherein said disk further includes a bush eccentrically mounted in the disk and receiving said pole member.
Claim 8
Dependent Claim
30 words
A ski pole as claimed in claim 3 wherein said disk is of varying height and is a maximum at said scraper means and diminishes therefrom to a minimum height.
Claim 9
Dependent Claim
28 words
A ski pole as claimed in claim 7 wherein the variation of height of the disk between maximum and minimum is in a ratio between 2:1 and 3:1.
Claim 10
Dependent Claim
36 words
A ski pole as claimed in claim 7 wherein the coupling means comprises an extension and an adjacent slot on said disk, the extension of one disk being fittable into the slot of the other disk.
Claim 11
Dependent Claim
16 words
A ski pole as claimed in claim 7 wherein said disk has a curved upper surface.
Claim 12
Dependent Claim
31 words
A ski pole as claimed in claim 7 wherein a straight line drawn between the minimum and maximum height of the disk forms an angle of 45° with said pole member.
Claim 13
Dependent Claim
20 words
A ski pole as claimed in claim 1 wherein said disk has a lower concave surface with a beaded edge.
Claim 14
Dependent Claim
17 words
A ski pole as claimed in claim 12 wherein said beaded edge includes peg-like arresters projecting therefrom.
Claim 15
Dependent Claim
26 words
A ski pole as claimed in claim 1 including additional coupling means comprising permanent magnet means supported by said disk for joining said poles for transport.
Claim 16
Dependent Claim
39 words
A ski pole as claimed in claim 1 wherein said tip includes a peg detachably coupled to said pole member, a collar extending axially from said peg, an extension extending axially from said collar and having an end face.
Claim 17
Dependent Claim
39 words
A ski pole as claimed in claim 15 wherein said collar has concentric annular edges defining steps with said peg and extension, said steps having different radii with the step of greater radii being further from said end face.
Claim 18
Dependent Claim
14 words
A ski pole as claimed in claim 15 wherein said end face is concave.
Claim 19
Dependent Claim
13 words
A ski pole as claimed in claim 15 wherein said collar is cylindrical.
Claim 20
Dependent Claim
13 words
A ski pole as claimed in claim 15 wherein said collar is conical.
Claim 21
Dependent Claim
23 words
A ski pole as claimed in claim 1 wherein said pole member comprises separable parts and means for lockably securing said parts together.
Claim 22
Dependent Claim
21 words
A ski pole as claimed in claim 20 wherein said separable parts are separable between said hand-engaging end and said disk.
Claim 23
Dependent Claim
56 words
A ski pole as claimed in claim 21 in combination with a ski on which loop retainers are secured, said separable parts being respectively insertable into said loop retainers and then locked by said locking means to secure the pole member in said loop retainers so that said pole member can be locked to said ski.
Claim 24
Dependent Claim
40 words
A ski pole as claimed in claim 20 wherein said means for lockably securing said parts together comprises engageable lock members on said parts and a slidable sheath on one of said parts for covering said lock members when engaged.
Claim 25
Dependent Claim
41 words
A ski pole as claimed in claim 20 comprising a handgrip on said pole member at said hand-engaging end, said means for lockably securing the parts together being proximate said handgrip whereby the handgrips of two pole members can be interchanged.
