Abstract
Abstract A ski is equipped in the middle section of its surface area with a spring board, mounted in an axial direction, whose front part is affixed rigidly to the ski, being fastened in or supported in such a way that a hinged leg, which carries the ski-binding and which adjoins in a rearward direction, can perform resilient swing movements, and which exerts a torque on the ski if the proper stress is exerted, which tends to lift the front part of the ski and to weigh down the rear.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
123 words
A ski assembly, which comprises: a ski; a spring board, disposed on a central section of said ski, arranged along the longitudinal axis of said ski on an upper surface thereof; said spring board comprising a front hinged leg connected to said ski; and, a rear hinged leg, for carrying a ski binding, connected to said front leg of said spring board such that said rear hinged leg is vertically swingably movable wherein said hinged front leg of said spring board is a leaf spring J-shaped with respect to the longitudinal axis of said ski and wherein said ski assembly further comprises a rear ring-shaped leaf spring interconnecting said rear hinged leg of said spring board and an upper surface of said ski.
Claim 2
Dependent Claim
123 words
A ski assembly, which comprises: a ski; a spring board, disposed on a central section of said ski, arranged along the longitudinal axis of said ski on an upper surface thereof; said spring board comprising a front hinged leg connected to said ski; and, a rear hinged leg, for carrying a ski binding, connected to said front leg of said spring board such that said rear hinged leg is vertically swingably movable wherein said hinged front leg of said spring board is a leaf spring J-shaped with respect to the longitudinal axis of said ski and wherein said ski assembly further comprises a rear ring-shaped leaf spring interconnecting said rear hinged leg of said spring board and an upper surface of said ski.
Claim 3
Dependent Claim
32 words
A ski assembly as set forth in claim 1, wherein said front hinged leg is connected to said ski about 1/3 of the ski length from the forward end of said ski.
Claim 4
Dependent Claim
39 words
A ski assembly as set forth in claim 1, wherein said hinged front leg of said spring board is conformed about an elastic cylinder the longitudinal axis of which is disposed perpendicular to the longitudinal axis of said ski.
Claim 5
Dependent Claim
21 words
A ski assembly as set forth in claim 1, wherein said front and rear leaf springs have longitudinal slits formed therein.
Claim 6
Dependent Claim
44 words
A ski assembly as set forth in claim 1, further comprising mechanical dampening means connected between said rear leaf spring and the upper surface of said ski for reducing swing of said spring board and for altering spring characteristics of said rear leaf spring.
Claim 7
Dependent Claim
44 words
A ski assembly as set forth in claim 1, further comprising fluid dampening means connected between said rear leaf spring and the upper surface of said ski for reducing swing of said spring board and for altering spring characteristics of said rear leaf spring.
Claim 8
Dependent Claim
55 words
A ski assembly as set forth in claim 1, further comprising dampening means connected between said rear leaf spring and the upper surface of said ski for altering spring characteristics of said rear leaf spring and buffer means disposed on a lower surface of said rear hinged leg for limiting swing of said spring board.
Claim 9
Dependent Claim
44 words
A ski assembly as set forth in claim 1, further comprising support means for said front and rear leaf springs disposed on said upper surface of said ski, through which said front and rear leaf springs may be longitudinally adjustably anchored to said ski.
Claim 10
Dependent Claim
111 words
A ski assembly which comprises: a ski; a spring board, including a front and rear end portion, supported at a spacing along the longitudinal axis of the ski in its central section on an upper surface thereof, which can achieve vertical swinging movements; and, resilient means connecting said front and rear end portions of said spring board to said ski such that a resilient swinging movement of said spring board is thereby produced wherein said resilient means comprises a leaf spring including a loop portion, and said ski assembly further comprises an elastic cylinder disposed within said loop portion of said leaf spring perpendicular to the longitudinal axis of said ski.
Claim 11
Dependent Claim
111 words
A ski assembly which comprises: a ski; a spring board, including a front and rear end portion, supported at a spacing along the longitudinal axis of the ski in its central section on an upper surface thereof, which can achieve vertical swinging movements; and, resilient means connecting said front and rear end portions of said spring board to said ski such that a resilient swinging movement of said spring board is thereby produced wherein said resilient means comprises a leaf spring including a loop portion, and said ski assembly further comprises an elastic cylinder disposed within said loop portion of said leaf spring perpendicular to the longitudinal axis of said ski.
Claim 12
Dependent Claim
20 words
A ski assembly as set forth in claim 9, wherein said cylinder comprises a solid cylinder made of rubber material.
Claim 13
Dependent Claim
17 words
A ski assembly as set forth in claim 9, wherein said leaf spring is provided with slits.
Claim 14
Dependent Claim
100 words
A ski assembly which comprises: a ski; a spring board, including a front and rear end portion, supported at a spacing along the longitudinal axis of the ski in its central section on an upper surface thereof, which can achieve vertical swinging movements; and, resilient means connecting said front and rear end portions of said spring board to said ski such that a resilient swinging movement of said spring board is thereby produced wherein said resilient means comprises; a rear leaf spring including a loop portion; and, a dampening means disposed within said loop portion of said rear leaf spring.
Claim 15
Dependent Claim
100 words
A ski assembly which comprises: a ski; a spring board, including a front and rear end portion, supported at a spacing along the longitudinal axis of the ski in its central section on an upper surface thereof, which can achieve vertical swinging movements; and, resilient means connecting said front and rear end portions of said spring board to said ski such that a resilient swinging movement of said spring board is thereby produced wherein said resilient means comprises; a rear leaf spring including a loop portion; and, a dampening means disposed within said loop portion of said rear leaf spring.
