Title:
引張バネ及び人体サポート装置
Document Type and Number:
Japanese Patent JP6963656
Kind Code:
B2
Abstract:
To achieve weight saving of a tension spring, and to achieve weight saving and simplification of a structure of a human body support device.SOLUTION: A tension spring 20 includes: a wire engaging part 20B to put a load into; and an elastic tube 44 having a sealed space to enclose gas into in the inside, and increased in a dimension to a tension direction by pulling the wire engaging part, and decreased in a dimension to a direction orthogonal to the tension direction so as to reduce a cubic volume in the sealed space as a result, and generating in the wire engaging part 20B, resilience to an opposite direction to the tension direction due to that gas in the sealed space is compressed. A waist support device 10 includes a femoral arm 16 and an upper body side frame 18 attached to a user, and the tension spring 20 provided between the femoral arm 16 and the upper body side frame 18, and pulled through displacement of the upper body side frame 18 to one side to the femoral arm 16.SELECTED DRAWING: Figure 2
