The present invention relates to a spring cartridge for a ski binding, wherein the ski binding has a rotatable front binding part for attachment of a ski boot, and is in particular a telemark ski binding. In the binding the spring cartridge provides tension to a biasing cable which biases the rotatable front binding part, so as to rotate the front binding part so that an attached ski boot would be brought into contact with the ski to which the ski binding is attached. The spring cartridge comprises an extended hollow housing open at both ends, a compression spring held within the extended hollow housing and a pressure stub held partly within the compression spring. The pressure stub is structured with an extended portion having a cross dimension smaller than the interior size of the compression spring and a head having a larger size than the interior size of the compression spring. The extended portion extends within the internal hollow of the compression spring and is also hollow and provided with an internal screw thread in the hollow section for threadable engagement with an external screw thread at the end of a biasing cable of a ski binding, the biasing cable being threadable through the center of the compression spring to the pressure stub. With rotation of the pressure stub this would thus lead to a change in the amount of the biasing cable held within the hollow section, when present, and thus change the amount of compressive force acting on the compression spring.

1. A spring cartridge for a ski binding having a rotatable front binding part for attachment of a ski boot, in particular a telemark ski binding, the spring cartridge providing tension to a biasing cable which biases the rotatable front binding part, so as to rotate the front binding part so that an attached ski boot would be brought into contact with the ski to which the ski binding is attached, the cartridge comprising: an extended hollow housing open at both ends, a compression spring held within the extended hollow housing and a pressure stub held partly within the compression spring; whereinthe pressure stub is structured with an extended portion having a cross dimension smaller than the interior size of the compression spring and a head having a larger size than the interior size of the compression spring, wherein the extended portion extends within the internal hollow of the compression spring and is also hollow and provided with an internal screw thread in the hollow section for threadable engagement with an external screw thread at the end of a biasing cable of a ski binding, the biasing cable being threadable through the centre of the compression spring to the pressure stub; whereinrotation of the pressure stub would thus lead to a change in the amount of the biasing cable held within the hollow section, when present, and thus change the amount of compressive force acting on the compression spring. 2. The spring cartridge of claim 1, further comprising: a rotatable adjustment knob held in one of the open ends of the extended hollow housing, wherein the rotatable adjustment knob has a first mating structure held within the extended hollow housing which matches with a second mating structure on the head of the pressure stub such that when in mated engagement, rotation of the rotatable adjustment knob leads to rotation of the pressure stub. 3. The spring cartridge of claim 1, wherein the compression spring and pressure stub are held within the extended hollow housing by means of a reduced cross-section at both ends ensuring that the openings defined at the ends are smaller than the outer dimension of the compression spring and head of the pressure stub. 4. The spring cartridge of claim 2, wherein the rotatable adjustment knob has either indents or protrusions on the portion located outside of the extended hollow housing which interact with appropriate protrusions or indents, respectfully, on either the extended hollow housing or the ski binding when the spring cartridge is mounted therewith, such that rotation of the adjustment knob proceeds in a click-wise or rotationally stepped manner. 5. The spring cartridge of claim 2, wherein the portion of the rotatable adjustment knob positioned outside of the extended hollow housing is structured with a plurality of teeth around the outer rim and/or with an appropriate structure for receiving a screwdriver. 6. The spring cartridge of claim 2, wherein the rotatable adjustment knob has a reduced cross-sectional part which is slightly smaller than the size of the hole at the end of the extended hollow housing, and two larger cross-sectional sections either side of this, one positioned within the extended hollow housing and the other positioned outside of the extended hollow housing, with cross-sectional sizes larger than the size of the hole. 7. The spring cartridge of claim 2, wherein the extended hollow housing is cylindrical. 8. The spring cartridge of claim 2, wherein the first mating structure on the rotatable adjustment knob is provided by a slot and the second mating structure is provided by shaping the entire head of the pressure stub such that it will engagingly fit within the slot. 9. A ski binding for a ski wherein the ski binding comprises: a rotatable front binding part for attachment of a ski boot, the rotatable front binding part being rotatably connected to a main part of the ski binding; anda biasing cable connected between the rotatable front binding part and the main part which is held under tension by means of the spring cartridge according to claim 2. 10. The ski binding of claim 9, wherein the spring cartridge is held in the main part of the ski binding and the biasing cable is attached between the rotatable front binding part and the pressure stub, such that rotation of the rotatable front binding part will draw the biasing cable through the spring cartridge and by means of the pressure stub will compress the compression spring. 11. The ski binding of claim 9, wherein the spring cartridge is held in the rotatable front binding part of the ski binding and the biasing cable is attached between the main part and the pressure stub, such that rotation of the rotatable front binding part will draw the biasing cable through the spring cartridge and by means of the pressure stub will compress the compression spring. 12. The ski binding of claim 9, wherein two spring cartridges are provided on the rotatable front binding part generally parallel and facing in the same direction, and the biasing cable passes from the pressure stub of the first spring cartridge to the pressure stub of the second spring cartridge via a looping post provided on the main part of the ski binding, wherein with rotation of the rotatable front binding part the looping post stops translational movement of the biasing cable with respect to the main part of the ski binding and thus leads to the biasing cable being drawn through each of the two spring cartridges against the biasing force from each compression spring. 13. The ski binding of claim 12, wherein the looping post is held in a releasable manner in the main part of the ski binding, and wherein the looping post can be manually released, and slideably moved toward the spring cartridges so as to remove the tension in the biasing cable and from the compression springs.
