Definitions

  • This invention is related to a foot roller means including a frame provided between front and rear wheel or roller units, wherein the frame presents an arched or arcuate portion which is elastically resilient to permit resiliency in the foot roller means, and at least one spring means is associated to the foot roller means,
  • said spring means being operative at all times to increase the radius of the arcuate portion of the frame.
  • the present invention is related to a foot roller means of the kind comprising in a conventional manner a frame provided between front and rear wheel or roller units, said frame securing and supporting a foot of the user of the foot roller means.
  • Object of the invention is to provide a foot roller means having a frame providing resiliency and elasticity when tramping off, the aim of the invention being more particularly to provide a foot roller means in which, on one hand, the resiliency or elasticity of the frame will be possible to maintain under practically unlimited time independent of the material and design of the frame, on the other said resiliency may be varied in dependence of occurent load, e.g. in dependence of the weight of the runner.
  • a foot roller means which is in accordance with the principle of the invention primarily characterized by the combination, that the frame presents an arched or arcuate portion which is elastically resilient to permit resiliency ofthe foot rollermeans, and that at least one spring means is associated to the foot roller means, said spring means being at all times operative to decrease the radius of the arcuate portion of the frame.
  • This spring means enables the arcuate portion of the frame, following each terminated tramp-off and the planing out of the portion in question associated thereto, on one hand to swiftly and safely return to its initial arched form, the runner being aided in lifting his foot and leg, and on the other, following said action, to provide a resilient or elastic backing at a renewed tramp-off.
  • this resiliency or elasticity in the foot roller means is assured independent of the choice of material in the frame so as to avoid every risk of a deteriorated resiliency through fatigue of the frame material, in that the resilient device proper by itself is possible to provide for the return of the frame portion into its initial form.
  • the resilient means permits of a selective control of the resiliency, for example in dependence of the runners weight or in dependence of other individual wants or desires with the runner.
  • FIG. 1 is a partial cross sectional side view of a foot roller means according to a first embodiment of the invention
  • FIG. 2 a similar side view of a second, alternative embodiment of the foot roller means of the invention
  • FIG. 3 an enlarged cross sectional view of part of a foot roller means showing an alternative part of the invention
  • FIG. 4 a further alternative embodiment similar to that shown in FIG. 1.
  • 1 designates a front wheel, 2 a rear pair of wheels, and 3 a frame of the roller means provided between said two wheel units.
  • On the frame 3 is in a manner known per se provided a clamping device 4 to retain the runners foot on the frame.
  • the frame 3 exhibits an arched or arcuate portion 5 which is elastically resilient to permit resiliency in the foot roller means, besides which at least one spring means generally designated by 6 is associated to the foot roller means, said spring means being at all times operative to decrease the radius of the arcuate portion 5 of the frame.
  • a l I As appears clearly by FIG. 1 the spring means 6 is provided below the frame 3, more particularly it is connected to the lower side of the frame.
  • the spring means 6 includes in this case an individual spring element 7 which, in accordance with the preferred embodiment of the invention, is connected with means to vary the spring force of the element.
  • the spring means 6 includes a substantially rigid or irresilient part 8 in the form of a rod, which is e.g. by means of a pivotable bracket 9 attached to or adjacent to one end of the frame, in this case the front end of the frame. From the front end of the frame the rod 8 extends below the frame and projects beyond or through a backing 10 disposed at or adjacent to the opposite end of the frame, in this case the rear end.
  • the spring element 7 has the form of a compression spring which is provided between the stop 11 and the backing 10. Thereby the spring will tend toincrease the distance between the stop and the backing and thus increase the distance between the backing 10 and the bracket 9 and consequently tend to decrease the radius of curvature of the frame portion 5.
  • the spring force of the compression spring 7 can be decreased or increased as needed whereby different resiliency will be obtained in the frame portion 5.
  • the rod 8 shown in FIG. 1 may be replaced by a tension spring, e.g. an elongate body of elastically resilient material the two opposite ends of which are attached to or connected to the frame at or adjacent to the two opposite ends thereof.
  • a tension spring 12 which is connected to the two opposite ends of the frame 3 through rods 13.
  • the spring 12 may be exchangeable so as to make an exchange possible between springs having a great and small elasticity or spring force respectively.
  • a spring means 6 which in accordance with a preferred embodiment of the invention includes at least one progressively operating spring element 14, which is operative to increase, in response to increasing load or deflection of the arcuate frame portion, the resistance against such deflection.
  • the elastic spring 14 may as illustrated in FIG. 3 be a simple spring element having decreasing pitch, or be assembled of two or a plurality of spring elements having different spring characteristics.
  • FIG. 4 finally an embodiment is shown in which, in the space between the lower side of the arcuate frame portion 5 and the rigid part 8 extending between the two ends of the frame, at least one spring element 15 is provided, the spring action of which is directed transversely to the longitudinal direction of the frame or portion.
  • This spring element is of advantage in that it will take up loads which are directed parallel to the proper operating direction of the spring.
  • a resilient foot roller comprising:
  • a frame connected to said front wheel unit and said rear wheel unit, said frame having a continuous elastically resilient, downwardly curving, arcuate portion longitudinally extending between said front and rear wheel units and having two opposite end portions, said arcuate portion for permitting resilience of the foot roller;
  • clamping means attached to said frame for retaining the foot of a user of said foot roller
  • adjusting means connected to said spring means for varying the spring force of said spring means.
  • said spring means includes at least one progressively operating spring element operative to, in response to increasing load or deflection of the arcuate frame portion, increase the resistance to such deflection.
  • said foot roller further comprises first and second attaching means for supporting respective ends of said substantially rigid portion at respective end portions of said arcuate portion and wherein one end of said substantially rigid portion is axially displaceable with respect to said respective attaching means and extends therebeyond;
  • said adjusting means comprises a stop on said extending end of said substantially rigid portion, said stop being axially displaceable on said extending end;
  • said spring element is a compression spring disposed between said stop and said respective attaching means.
  • a resilient foot roller according to claim 4 wherein in the space between the underside of said arcuate frame portion and said rigid portion at least one spring element is provided, the spring action of which is directed transversely to the longitudinal direction of the frame.
