Abstract
Abstract A ski provided with a multiple number of spaced-apart members, preferably in the form of rotatable beveled discs mounted along the side wall of the ski at its central binding portion, with each of the members defining a lower metal apex, such as the outer peripheral edge of the beveled disc, terminating not substantially below the plane of the bottom running surface of the ski laterally spaced outwardly from the side wall, so that a line intersecting said apex and the closest adjacent point of the lower outward edge of the bottom running surface forms an acute angle of 0 to 20° with said running surface plane.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
113 words
In a snow ski having a bottom running surface and side walls, the improvement which comprises a multiple number of spaced-apart members mounted along the side wall at the central binding portion of the ski, each said member defining a lower metal apex terminating not substantially below the plane of said running surface, laterally spaced outwardly from the side wall, with a free lateral space between it and the adjacent lower outer edge of the bottom surface, so that a line intersecting said apex and the closest adjacent point of the lower outward edge of the bottom running surface forms an acute angle of about 0 to 20° with said running surface plane.
Claim 2
Dependent Claim
113 words
In a snow ski having a bottom running surface and side walls, the improvement which comprises a multiple number of spaced-apart members mounted along the side wall at the central binding portion of the ski, each said member defining a lower metal apex terminating not substantially below the plane of said running surface, laterally spaced outwardly from the side wall, with a free lateral space between it and the adjacent lower outer edge of the bottom surface, so that a line intersecting said apex and the closest adjacent point of the lower outward edge of the bottom running surface forms an acute angle of about 0 to 20° with said running surface plane.
Claim 3
Dependent Claim
17 words
Improvement according to claim 1, in which said acute angle is an angle between 0 and 10°.
Claim 4
Dependent Claim
18 words
Improvement according to claim 1, in which said acute angle is an angle of between 0 and 6°.
Claim 5
Dependent Claim
24 words
Improvement according to claim 1, in which about three to 10 members are spaced apart over a length of about 5 to 14 inches.
Claim 6
Dependent Claim
20 words
Improvement according to claim 1, in which the apexes of said members are in the form of curved knife edges.
Claim 7
Dependent Claim
24 words
Improvement according to claim 1, in which said members are adjustably mounted along the side wall of said ski to vary said acute angle.
Claim 8
Dependent Claim
99 words
In a snow ski having a bottom running surface and side walls, the improvement which comprises a multiple number of spaced-apart discs mounted along the side wall at the central binding portion of the ski, said discs each having an outer peripheral metal edge extending not substantially below the plane of said running surface and laterally spaced outward from the side wall, so that a line intersecting its lowest point and the closest adjacent point of the lower outward edge of the bottom running surface forms an acute angle of about 0 to 20° with said running surface plane.
Claim 9
Dependent Claim
99 words
In a snow ski having a bottom running surface and side walls, the improvement which comprises a multiple number of spaced-apart discs mounted along the side wall at the central binding portion of the ski, said discs each having an outer peripheral metal edge extending not substantially below the plane of said running surface and laterally spaced outward from the side wall, so that a line intersecting its lowest point and the closest adjacent point of the lower outward edge of the bottom running surface forms an acute angle of about 0 to 20° with said running surface plane.
Claim 10
Dependent Claim
26 words
Improvement according to claim 7, in which each said disc is a beveled disc, with said edge being defined at its circumferential portion of greatest diameter.
Claim 11
Dependent Claim
17 words
Improvement according to claim 8, in which said peripheral metal edge is a hard metal knife edge.
Claim 12
Dependent Claim
12 words
Improvement according to claim 7, in which said discs are rotatably mounted.
Claim 13
Dependent Claim
24 words
Improvement according to claim 7, in which three to 10 discs are provided spaced apart over a length of about 5 to 14 inches.
Claim 14
Dependent Claim
63 words
Improvement according to claim 10 in which said discs are beveled discs having an outer diameter of about one-half to three-fourths inch, a thickness between about one-eighth and three-eighths inch, and beveled so that their greater diameter extends outwardly from the ski, said bevel being at an angle of 5 to 30° to their axes, and said first-mentioned angle between 0 and 10°.
Claim 15
Dependent Claim
22 words
Improvement according to claim 12, in which said discs are adjustably mounted on said wall to allow variation of said first-mentioned angle.
Claim 16
Dependent Claim
20 words
Improvement according to claim 13, in which said discs are mounted on an eccentrically turnable bushing to allow said adjustment.
Claim 17
Dependent Claim
16 words
Improvement according to claim 7, in which said discs are adjustably mounted to vary said angle.
Claim 18
Dependent Claim
20 words
Improvement according to claim 15, in which said discs are mounted on an eccentrically turnable bushing to allow said adjustment.
