  • Patent number: 10899405
    Abstract: A bicycle brake lock device and a bicycle brake assembly comprising the same. The device comprises a separate lock means that can restrain a first and a second rotation link of a bicycle brake in a brake operating state to prevent the rotation thereof. Therefore, even without a separate lock device such as a lock, the lock means can simply operate in a lock mode to make the riding of a bicycle impossible, and thus can prevent the bicycle from being stolen. Also, a user can safely fix and restrain a bicycle through a lock means by carrying only a lock key without carrying a separate big and heavy lock device, and thus more conveniently use the bicycle. In particular, a bicycle can be prevented from being stolen even by use of a tool such as a cutter, and thus achieves an enhanced safety from the bicycle theft.

  • Patent number: 8328217
    Abstract: Conventional linkages between bicycle handlebar-mounted controls and rear brakes and gears are unable to accommodate unlimited rotation of the handlebars as is required on some so-called “freestyle” bicycles. A prior attempt to solve the problem employs a linkage comprising a bearing having two parts that are relatively rotatable about an axis. However this proposal is unable to handle situations where there are two or more mechanisms to be controlled e.g. a rear brake and a gear. The problem is solved by using multiple bearings (15, 16, 17) that share a common axis (X-X) of rotation but are located at different radial positions with respect to the axis. This avoids interference between the different linkages and makes it possible to locate the linkages around a stem on which the front wheel fork of the bicycle is mounted. A possible suitable location may be within a head tube of the bicycle frame. The invention is not limited to use with bicycles and can be employed in robotic and other machines.
