Claims
- 1. A wheeled device comprising:
- a longitudinally-extending frame supporting a plurality of wheels;
- a pivotal member mounted above said frame for forward and rearward pivotal movement relative to said frame about a first axis;
- a braking element connected to the frame for movement relative to the frame towards and away from a braking surface; and
- a flexible traction element connecting said pivotal member and said braking element,
- at least a portion of said flexible traction element arranged such that backward rotation of said pivotal member creates a traction force in said flexible traction element and causes said braking element to move towards said braking surface.
- 2. The device of claim 1, wherein said braking element is constituted by a block which interacts with the ground, said block being connected to said traction element.
- 3. The device of claim 1, including an elastically deformable element arranged to cause said braking element to pivot about said second axis away from said braking surface.
- 4. The device of claim 1, wherein said braking element is pivotally connected to said frame for pivotal movement about a second axis.
- 5. The device of claim 1, wherein said traction element is constituted by a cable, a first portion whereof is positioned externally of and to the rear of said pivotal member.
- 6. The device of claim 1, wherein said traction element comprises a cable that is slidingly associated with an adapted sheath that runs from adjacent the rear of said pivotal member.
- 7. The device of claim 1, wherein the working length of said traction element is adjustable.
- 8. The device of claim 7, wherein the working length of said traction element is adjustable by a cylindrical knob which is arranged longitudinally to said pivotal member and has a threaded axial seat for a complementarily threaded stop element which is associated with an end of said traction element.
- 9. The device of claim 1, wherein said braking element has, in a transverse cross-section, an arc-like shape with a concavity directed toward an adjacent said wheel, and said braking element is pivotably connected to said frame for pivotal movement about a second axis toward said adjacent wheel in response to said traction force.
- 10. The device of claim 1 including means for selecting the activation of said braking element upon either a forward or backward flexing of said pivotal member.
- 11. A skate comprising:
- a longitudinally-extending frame adapted to support a plurality of wheels;
- a quarter mounted above said frame for forward and rearward pivotal movement relative to said frame about a first axis;
- a braking element pivotally connected to the frame for pivotal movement relative to the frame about a second axis towards and away from a braking surface; and
- a flexible traction element connecting said quarter to said braking element,
- at least a portion of said flexible traction element being guided on said skate such that backward rotation of said quarter creates a traction force in said flexible traction element and causes pivoting of said braking element about said second axis towards said braking surface.
