Claims
- 1. A torque control for use in conjunction with a component pivotally mounted to a support structure for pivotal movement about a pivot pin, said torque control comprising:
- at least one cylindrical resistance element adapted to be fixedly mounted to one of said component or structure in spaced relationship to the pivot pin, said resistance element having a predetermined diameter; and
- a member composed of a resilient polymeric material for attachment to the other of the component or structure, said member having at least one arcuate slot spaced from the pivot pin and receiving therein said resistance element for movement longitudinally therethrough as the component pivots about the pivot pin; said slot having a width dimension relatively smaller than said diameter of said resistance element, whereby a desired frictional resistance is obtained as the component is pivotally moved, and wherein means is provided to continuously vary the force exerted by the sides of said slot on said resistance element as it travels through substantially the entire arcuate length of said slot whereby a variable frictional resistance is provided on said resistance element as it slides along said slot.
- 2. The torque control of claim 1 in which the means for varying the force exerted by the sides of said slot on said resistance element comprises one of said sides being part of a wall which is cutout between the ends of said slot permitting said wall and one side to flex, as said resistance element travels through said slot, the force exerted by said one side of said wall on said resistance element varying depending on the distance the resistance element is from said cutout part of said wall.
- 3. The torque control of claim 2 in which said member comprises a body having an opening for receiving said pivot pin, said slot being arcuate in shape and spaced from said opening; the walls of said slot being arcuate and spaced different radial distances from said opening, the closer wall being the inner wall and the more distant wall being the outer wall; said cutout in said outer wall of lesser width than the width of said resistance element, said cutout extending from the slot to an outer edge of said member whereby said outer wall is permitted to flex as said resistance element travels through said slot, the force exerted by said outer wall of said walls on said resistance element varying depending on the distance the resistance element is from said cutout.
- 4. The torque control of claim 1 in which more than one arcuate slot and resistance element is provided, such arcuate slots and resistance elements being spaced equally about said pivot pin; said slots each having means to continuously vary the force exerted by their sides on said resistance element located therein as it travels in its slot.
- 5. The torque control of claim 4 in which all of said slot and resistance element combinations are identical.
- 6. The torque control of claim 1 in which the resistance element is a cylindrical pin of slightly greater diameter dimension than said width of said slot.
- 7. The torque control of claim 2 in which the resistance element is a cylindrical pin of slightly greater diameter dimension than said width of said slot.
- 8. The torque control of claim 3 in which the resistance element is a cylindrical pin of slightly greater diameter dimension than said width of said slot.
- 9. The torque control of claim 4 in which the resistance elements are cylindrical pins of slightly greater diameter dimension than said width of said slots.
- 10. The torque control of claim 5 in which the resistance elements are cylindrical pins of slightly greater diameter dimension than said width of said slots.
- 11. The torque control of claim 2 in which more than one arcuate slot and resistance element is provided, such arcuate slots and resistance elements being spaced equally about said pivot pin; said slots each having means to continuously vary the force exerted by their sides on said resistance element located therein as it travels in its slot.
- 12. The torque control of claim 3 in which more than one arcuate slot and resistance element is provided, such arcuate slots and resistance elements being spaced equally about said pivot pin; said slots each having means to continuously vary the force exerted by their sides on said resistance element located therein as it travels in its slot.
