Abstract
Abstract This invention is related to a braking device for foot roller means, in particular roller skis, of the kind including a frame supporting and securing the runner''s foot, and rollers or wheels provided on shafts, and brake linings or other brake elements designed for one or a plurality of the wheels to effect the braking of the roller means by moving the frame and the wheel closer to each other, wherein the wheel and the frame are movable relative to each other in an axial direction and at least one spring is provided to tend at all times to space the wheel and the frame from each other, wherein the wheel and the frame are movable to each other in order to obtain a braking action, preferably by tilting the frame relative to the running substratum or by moving the foot transversely to the running direction, against the action of the spring.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
150 words
In a braking device for foot roller means, in particular roller skis, for movement of an object along a substrate, including a frame means, secured to and for supporting a portion of the object being rolled on the roller ski; a shaft slidably extending through a bearing on the frame; at least one wheel rotatably mounted on the shaft; and braking means cooperative with the at least one wheel for effecting braking of the foot roller means when at least one wheel contacts the braking means, the improvement including: the frame being slidable on the shaft in the axial direction of the shaft; at least one spring means, engaging the wheel and the frame, for resiliently urging the wheel away from the frame; and the frame being movable against the urging of said spring means to thereby bring the braking means into cooperative contact with the wheel thereby effecting braking.
Claim 2
Dependent Claim
150 words
In a braking device for foot roller means, in particular roller skis, for movement of an object along a substrate, including a frame means, secured to and for supporting a portion of the object being rolled on the roller ski; a shaft slidably extending through a bearing on the frame; at least one wheel rotatably mounted on the shaft; and braking means cooperative with the at least one wheel for effecting braking of the foot roller means when at least one wheel contacts the braking means, the improvement including: the frame being slidable on the shaft in the axial direction of the shaft; at least one spring means, engaging the wheel and the frame, for resiliently urging the wheel away from the frame; and the frame being movable against the urging of said spring means to thereby bring the braking means into cooperative contact with the wheel thereby effecting braking.
Claim 3
Dependent Claim
14 words
Braking device according to claim 1, wherein said spring means is a compression spring.
Claim 4
Dependent Claim
15 words
Braking device according to claim 1, wherein the braking means is attached to the frame.
Claim 5
Dependent Claim
51 words
Braking device according to claim 3, wherein the braking means comprises a bracket adjustably mounted on the frame and a brake lining mounted on said bracket, said bracket being movable with respect to the frame such that the spacing between the brake lining and the wheel can be varied as desired.
Claim 6
Dependent Claim
15 words
Braking device according to claim 2, wherein the braking means is attached to the frame.
Claim 7
Dependent Claim
158 words
In a braking device for foot roller means, in particular roller skis, for movement of an object along a substrate, including a frame means, secured to, and for supporting a portion of the object being rolled on the roller ski; a shaft rotatably mounted in at least one bearing on the frame; at least one wheel rotatably mounted on the shaft; and braking means cooperative with the at least one wheel for effecting braking of the foot roller means when the at least one wheel contacts the braking means, the improvement including: the at least one wheel slidably engaging the shaft thereby being movable in the axial direction of the shaft; at least one spring means engaging the wheel and the frame for resiliently urging the wheel away from the frame; and the wheel being movable against the urging of said spring means to thereby bring the braking means into cooperative contact with the wheel thereby effecting braking.
Claim 8
Dependent Claim
158 words
In a braking device for foot roller means, in particular roller skis, for movement of an object along a substrate, including a frame means, secured to, and for supporting a portion of the object being rolled on the roller ski; a shaft rotatably mounted in at least one bearing on the frame; at least one wheel rotatably mounted on the shaft; and braking means cooperative with the at least one wheel for effecting braking of the foot roller means when the at least one wheel contacts the braking means, the improvement including: the at least one wheel slidably engaging the shaft thereby being movable in the axial direction of the shaft; at least one spring means engaging the wheel and the frame for resiliently urging the wheel away from the frame; and the wheel being movable against the urging of said spring means to thereby bring the braking means into cooperative contact with the wheel thereby effecting braking.
Claim 9
Dependent Claim
21 words
Braking device according to claim 6, wherein said spring means is a compression spring, provided between the wheel and the frame.
Claim 10
Dependent Claim
15 words
Braking device according to claim 7 wherein the braking means is attached to the frame.
Claim 11
Dependent Claim
15 words
Braking device according to claim 6 wherein the braking means is attached to the frame.
Claim 12
Dependent Claim
51 words
Braking device according to claim 9, wherein the braking means comprises a bracket adjustably mounted on the frame and a brake lining mounted on said bracket, said bracket being movable with respect to the frame such that the spacing between the brake lining and the wheel can be varied, as desired.
