BRIDGE METAL FIXTURE IN BICYCLE FRAME

Japanese Patent JP2998004

B2

PROBLEM TO BE SOLVED: To make upper and lower bridge metal fixtures the same parts to realize the commonness of the party, by providing in range a wire holding part, foldable in an orthogonal direction, to one side of a connecting part in a metal plate, for stretching over between right and left back forks or chain stays.
SOLUTION: A metal plate 1, for constituting a bridge in a bicycle frame, forms a length, to be stretched over between right and left back forks 8a, and 8b, and also forms connecting parts 2 and 3 on both ends. A wire holding part 4, protruded in a side surface direction crossing to the length wise direction of the plate 1 to be foldable in an orthogonal direction, is provided in range on one side connecting part 3, and a fixed part 6, similarly protruded in a crossing side surface direction to the lengthwise direction to be folded in an orthogonal direction to have a fitting hole 7, is formed on the center part of the plate 1. Consequently, the upper and lower bridge metal fixtures can be made the same parts to realize the commonness of the parts.
