Abstract
The invention relates to a locking device comprising a rotatable shaft coupling (19, 63) provided with a hollow (21, 65) and a shaft arrangement (3, 61) comprising a shaft (25, 71) arranged in the hollow and which connects the shaft and the shaft coupling so that they are jointly rotatable for transmission of at least one rotational movement or rotational force between the shaft and the shaft coupling. The invention also relates to a shaft arrangement (3, 61) shaped to be connected with a locking device comprising a rotatable shaft coupling provided with a hollow.
Claims12
A shaft arrangement designed to be connected with a locking device (1) comprising a rotatable shaft coupling (19, 63) provided with a hollow section defining an inner surface (21, 65), said shaft arrangement (3, 61) comprises a shaft (25, 71) shaped to be arranged within the hollow section, the shaft comprises at least one rounded slide surface (47) shaped to avoid engagement with the inner surface of the hollow section;
- a play (29, 73) is defined between the inner surface of the hollow section and the shaft (25, 71);
- the shaft arrangement further comprises an intermediate element (37) shaped to be arranged within the play;
- wherein, when a rotational movement or force is transmitted in a first direction, said shaft will engage the intermediate element (37) so that the shaft (25, 71) and the shaft coupling (19, 63) jointly rotate to transmit the movement or force to the locking device;
- wherein, when a rotational movement or force is transmitted in a second direction, said shaft (25, 71) will not engage the intermediate element (37), the movement or force is not transmitted to the locking device and also allows disengagement of the shaft (25, 71) from the shaft coupling (19, 63).
