Abstract

The device has two coupling elements mounted rotatably about a rotation axis and movable axially relative to each other. In a first axial relative arrangement of the two coupling elements, these are coupled to each other such that, at least when the first coupling element rotates in a first direction, torque can be transmitted from the first to the second coupling element. Via rotation of the first coupling element in a second direction, the two coupling elements can be moved axially apart at least until they reach a second axial relative arrangement. In the second axial relative arrangement, movement of a movable blocking element into a blocking position is enabled or enablable. With the blocking element in the blocking position and the coupling elements in the second axial relative arrangement, axial movement of the two coupling elements toward each other is blocked.

Dependent claims

A device for a bicycle, the device comprising:

a first coupling element;
a second coupling element;
a movable blocking element;
said first coupling element and said second coupling element being mounted rotatably about a rotation axis and being mounted so as to be axially movable relative to each other;
the device being configured such that:
in a first axial relative arrangement of said first coupling element and said second coupling element, said first coupling element and said second coupling element are coupled to each other such that, at least when said first coupling element rotates in a first rotational direction, torque is transmittable to said second coupling element;
with the aid of rotation of said first coupling element in a second rotational direction, said first coupling element and said second coupling element are movable axially apart at least to a second axial relative arrangement;
in said second axial relative arrangement, movement of said movable blocking element into a blocking position is enabled or is configured to be enabled;
and,
with said blocking element in said blocking position and said first coupling element and said second coupling element in said second axial relative arrangement, axial movement of said first coupling element and said second coupling element toward each other is blocked.
