Bicycle rear derailleur device () comprising a chain guide assembly () made up of two parts: a guiding cage () and a tension cage (). It also comprises a movable member () coupled to a base member () via a linking member () to align the chain guide assembly () with the different sprockets. Said tension cage () carries a tension pulley (), is pivotably coupled to the movable member () and is biased by a main spring or biasing member (). The guiding cage () carrying a guiding pulley (), and the tension cage () are both configured to move either jointly or independently of each other, such the distance between both pulleys () is fixed or free respectively, varying as a consequence the chain tension. To do so, the guiding cage () is pivotally coupled to the tension cage () comprising between them coupling means () that selectively and reversibly make both cages united or not.

Bicycle rear derailleur device

A freewheel mechanism comprising two coaxial carrying members for eventually transmitting torque there between, being both members axially fixed but rotatably mounted along an axis. This mechanism further comprises longitudinal pawls housed in cavities, predominantly radially disposed in one of the carrying members, arranged to engage and disengage with a toothed ring placed between said carrying members. This mechanism allows a partial declutch of the carrying members, due to said toothed ring is always forced by longitudinal pawls, to slide bi-directionally in the axial direction, being declutching the axial movement from a first clutch position corresponding to non-freewheeling, to a second declutch position corresponding to freewheeling, and being clutching the axial movement of the toothed ring from the second declutch position to the first clutch position.

Freewheel mechanism

Bicycle single-acted gear-shifting device (), comprising one front or rear derailleur () coupling a ratchet indexing mechanism () acted by only one single-acting slave-connector () attached to said ratchet indexing mechanism (), operated by a unidirectional operator mechanism () with optional multiple unidirectional handle operator units (). Said ratchet indexing mechanism () removably defines and holds a plurality of predetermined working stable positions of the derailleur's cage-plate () for each gearshift, and it comprises a ratchet-gear () with a pawls' system. And said unidirectional operator mechanism () comprises optional multiple unidirectional operator units () connected in parallel with the only single-acting slave-connector (), in order to indistinctly operate it, by means of a branched single-acting drive circuit () which can be arranged either using a hydraulic circuit (&#x2033;) acting by pushing, or using flexible cables (') and housings () to act by pulling.

Bicycle single-acted gear-shifting device and its unidirectional operator mechanism

A bicycle dual control device hydraulically operated, so that using one single device the cyclist may operate, by applying different hand pressures or taps from the handlebar, two unidirectional control mechanisms, preferably a brake and a bicycle gear-shifting mechanisms. The control device comprises two unidirectional control units within a single lever or handgrip attached to the handlebar, wherein each one of them comprises an acting member, an operating member connected to a control circuit and a coupling element which links the two previous members. In a preferred embodiment of the invention, the operating member related to the gear shifting is hydraulic and comprises a piston and a cylinder mounted integrated inside the brake acting member.
