Abstract
The cross-country ski binding is provided with two pins (3, 4) which are arranged with their corresponding rigid pin recesses (5, 6) one behind the other in the longitudinal direction of the ski; at least one pin is spring-loaded in a perpendicular direction to the ski by a spring element (2) in the form of a binding arm. In this way, the design is maintained flat and the spring travel is long and spring fore can be optimally adjusted. Insertion of the foot in the binding is also facilitated and the stability of the ski boot (9) around its vertical axis is good and the binding grips without and play. With this design numerous advantageous embodiments of the biding are possible.
Claims28
A ski binding for cross-country skis, said binding comprising:
- a first binding unit that is permanently attached to the ski;
- a second binding unit that forms a part of a ski shoe;
- two parallel shafts;
- a fixed shaft receiver associated with one said shaft;
- a second shaft receiver associated with the other said shaft;
- at least one spring element;
- said fixed shaft receiver holding it's associated shaft in a direction perpendicular to a major axis of the ski, the two shafts and their associated shaft receivers both connecting the binding units to each other and spaced from each other in the longitudinal direction of the ski and at least one of the shafts being loaded by said at least one spring element in a direction at least approximately perpendicular to the ski when the ski shoe is set on the ski.
A ski binding unit for cross country ski, said binding comprising:
- a first binding unit attached to the ski;
- a second binding unit that forms a part of a ski shoe;
- a first shaft disposed upon one of said binding units;
- a first shaft receiver disposed upon the other of said binding units, said first shaft receiver including means for retaining said first parallel shaft in a direction lateral to a major longitudinal axis of said ski;
- a second shaft disposed upon one of said binding units;
- said first shaft being parallel to said second shaft;
- a second shaft receiver disposed upon the other of said binding units;
- means for restraining said second shaft in said second shaft receiver so that the ski shoe is held flat on the ski, said second shaft receiver restraining said second shaft in a position spaced along the longitudinal axis of said ski from where said first shaft receiver retains first shaft.
