Abstract
A locking device for a bicycle or a corresponding lockable unit, which comprises a locking member swingable from a releasing position through a wheel of the lockable unit to a locking position and vice versa. A catch is provided to receive the free end of the locking member and a cylinder lock is attached to the other end of the locking member; and, in order to move the free end of the locking member into the catch and to remove it therefrom, the locking member has to be turned around a longitudinal axis. The swinging movement of the locking member between its locking and releasing positions is dependent on the turning position of the locking member so that the swinging movement can be carried out only when the locking member is in a certain turning position.
Claims15
A locking device for a lockable unit having a rotatable wheel positioned between a pair of stationary members, comprising
- a locking member swingable from a releasing position through the wheel to a locking position and vice-versa,
- a locking mechanism connected to said locking member and having an element which turns about a first axis,
- means connecting said locking member with one of said stationary members for movement relative thereto and with said other stationary member under the control of said locking mechanism, and
- means for turning said locking member about said first axis which is a longitudinal axis thereof for freeing said locking member from engagement with said other stationary member, said connecting means providing means for swinging said locking member about a second axis transverse to said first axis solely after said locking member has been turned about said first axis from a first position preventing swinging movement thereof to a second position thereof permitting swinging movement of said locking member about said second axis.
A locking device for a lockable unit having a rotatable wheel, comprising
- an elongate locking member having a turnably journalled end and a swingable free end, said locking member being swingable about an axis transverse to the axis of the wheel from a releasing position free of the wheel through the wheel to a locking position, and vice-versa;
- a catch receiving said free end in the locking position of said locking member;
- a locking mechanism attached to said journalled end for turning said locking member about a longitudinal axis;
- and
- means cooperating with said locking mechanism to control the turning of said locking member about said longitudinal axis for moving said free end into said catch and for removing it therefrom, said means including a locking member positioning means for positioning said locking member in a first position to permit swinging movement thereof and positioning said locking member in a second position to prevent swinging movement thereof.
