Patent number: 6908091Abstract: A cambering vehicle includes a front column, left and a right trailing arms each having a front portion pivotally attached to either the front column or a bracket attached thereto by a pivot axle which is preferably inclined relative to the bracket or the front column. A detachable latching device may be used to detachably latch the bracket, if so provided, and thus the trailing arms to the front column at the working position. The bracket and thus the trailing arm may be rotated relative to the front column to the folding position when the detachably latching device releases the bracket relative to the front column. The cambering vehicle may also include a link connect the trailing arms independent of the front column, and a braking mechanism to inhibit forward movement of the cambering vehicle.Type: GrantFiled: August 11, 2003Date of Patent: June 21, 2005Assignee: Unique Forces Company LimitedInventor: Jin Chen Chuang
