Double arch hover transfer buckling leaf spring device and magnet catch applying it

摘要

PROBLEM TO BE SOLVED: To enable an arch type jumping buckling plate spring used as a machine element to be supported at both ends by whatever arch forming method may be applied, reduce a load of both ends supporting and facilitate its application while preventing a useless deformation at the time of jumping buckling.;SOLUTION: A seat body 3 is fixed at a central part of a substantial elongated plate spring 1 to make a rigid assembly, each of the divided plate spring main body part is formed with an equal arch-shaped jumping buckling plate spring and then there is provided guide means 9 for limiting a motion of the seat body to a direction perpendicular to the plate spring to prevent useless deformation at the time of jumping buckling. Then, both end portions of the plate spring are formed with a cushion part having its section bent to support the plate spring at its both ends or a back side of the plate spring is provided with a substantial recess-shaped back plate spring 2, each of both ends of the back plate spring and the plate spring is connected by a connecting unit 7 that can be oscillated in front and back directions to support the central part of the back plate spring so as to generate jumping buckling of the same direction in a substantial simultaneous manner to both plate spring main body parts in a repetitive manner under a load more than a specified value to the seat body in any directions of front and back ones.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
