ABSTRACT:
A rotary handle gearshift actuator for operating bicycle gears. The gearshift actuator includes a rotatable housing and a stationary housing. The rotatable housing has a planar surface and including an outer cylinder extending outwardly from the planar surface, the outer cylinder having an inside wall and a recess defined axially in the inside wall. The stationary housing has a planar surface and an inner cylinder extending outwardly from the planar surface of the stationary housing. The inner cylinder has a distal end and a bayonet hook extending radially outwardly from the distal end, the bayonet hook being configured for sliding engagement with the recess of the outer cylinder of the rotatable housing. The inner cylinder of the stationary housing is dimensioned to dispose concentrically within the outer cylinder of the rotatable housing so as to form a bearing point and so that the bayonet hook extends axially beyond the planar surface of the rotatable housing thereby permitting the recess of the rotatable housing to be rotated away from the bayonet of the stationary housing and thereby preventing the inner and outer cylinders from separating axially. The gearshift actuator further includes a latching mechanism for rotatively latching the rotatable housing to the stationary housing.
