Title:
自転車を制御するための機械的リンク機構
Document Type and Number:
Japanese Patent JP5489042
Kind Code:
B2
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.
