Title:
マルチバネシステム
Document Type and Number:
Japanese Patent JP7402515
Kind Code:
B2
Abstract:
To provide a multi-spring system in which spring bodies in contact with each other in the thickness direction are suppressed from separately and irregularly vibrating and interfering with each other, damage to the spring body is suppressed, and the durability of a constant load spring unit is improved more than before.SOLUTION: A multi-spring system of the present invention comprises a bracket attached to a first member and a plurality of constant load spring units held in the bracket. Each of the constant load spring units includes a bobbin and a strip-like constant load spring section that is wound on the bobbin and attached at the tip to the second member. The constant-load spring section has a spring body that contacts the constant-load spring section of the adjacent constant-load spring unit in the thickness direction and an attachment section that is laminated to the spring body and attaches the spring body to the constant-load spring section of the adjacent constant-load spring unit. This prevents the spring bodies from separately and irregularly vibrating and interfering with each other and buckling.SELECTED DRAWING: Figure 9
