  • Publication number: 20180327048
    Abstract: Skewer for tightening a cycle wheel to the cycle frame, such skewer including a first end having a threaded portion cooperable with a female thread of a first frame portion, and a second end having axial abutment mechanisms for contacting a second frame portion, as well as drive mechanisms to enable a user to alternately exert a tightening torque or a loosening torque. A torque limiting mechanism operational in the tightening direction is positioned between the drive mechanisms and the rod. The skewer further includes a braking device to increase the torque required to initiate the rotation of the drive mechanisms in the loosening direction. The braking device includes two mutually contacting friction surfaces when the axial abutment mechanisms are in contact with the second frame portion. When the torque limiting mechanism is operational, the braking device becomes non-operational because the friction surfaces are no longer in mutual contact.

  • Publication number: 20160375950
    Abstract: A skewer for fixing a wheel to a cycle-type vehicle, comprising a rod extending along a longitudinal axis, a first end that includes structural elements that cooperate with the vehicle frame, and a second end that includes structural elements configured to cooperate with a device exerting a tightening torque, in which the rod includes a groove extending along the longitudinal axis over a first length, an element having a variable diameter and a second length, the second length being less than the first length, is received in the groove so as to be translationally movable along the longitudinal axis, and an elastic biaser longitudinally constrains the variable diameter element towards the second end. The variable diameter element is a split tubular ring whose diameter in the free state is greater than the maximum outer diameter of the rod; it is longitudinally constrained by a spiral spring, and a distribution ring is interposed between the spring and the variable diameter element.

  • Patent number: 9511975
    Abstract: The invention relates to a device for winding and locking a lace comprising a fixed support, a rotatable spool, a user-operable knob for driving the spool, and elements for blocking the spool. The blocking elements comprise at least one pawl having a retaining portion engaging at least one complementary projection of the support in the absence of a rotational force exerted by the user on the knob, a base rotationally driven when the knob rotates during loosening, a first bar carrying the retaining portion and being elastically deformable, an actuating portion carried by a second bar and away from the retaining portion, the pawl being configured so that, during loosening, the knob, via the actuating portion, disengages the retaining portion.
