Patent number: 8210324Abstract: A device for braking an elongated rotating body, includes at least two parts with coaxial conical surfaces, able to be slipped onto the body, and one, a so-called male cone, mounted integrally in rotation with the body, and the other, a so-called female cone, mounted fixed in rotation relative to the body. The female cone assumes the shape of a wheel with an axial bore with a conical bearing, and the male cone has a center recess. The cones are controlled in terms of axial relative movement by a control element. The male cone is, when the cones are close to one another, corresponding to the braking position, housed inside the axial bore of the female cone, with its conical external peripheral surface being held, by contact with a support, with the conical bearing of the female cone.Type: GrantFiled: June 17, 2008Date of Patent: July 3, 2012Assignee: France ReducteursInventor: Robert Blanchard

Patent number: 7810613Abstract: A cart braking device includes a swivel unit, a shaft unit and a braking unit which has a central shaft, an orientation member, a braking member and a base. The central shaft is coupled with the orientation member and has an elastic piece for moving the central shaft upward. A bottom of the orientation member has an orientation gear and a top of the braking member has a fixation gear corresponding to the orientation gear. The braking member is disposed in the base and includes two braking pads. An elastic member is disposed between the base and the braking member, and can move the braking member away from the base. When the braking pads are pressed against the wheel, the cart braking device stops the rotation of the wheel. When the orientation gear is engaged with the fixation gear, the cart braking device prevents the wheel from changing direction.Type: GrantFiled: November 29, 2007Date of Patent: October 12, 2010Inventor: Ching-Sung Lin
