発明の名称 (英語) ELASTIC MECHANISM
発明の概要(英語) In a spring mechanism 11, a negative spring mechanism 17D for biasing a loading plate 15 to the positive side of the z direction comprises a spring shaft 27D and an interspring 29D. The spring shaft 27D is rotatably connected to a fixed part 13 and is connected, via a slider 25D, to the loading plate 15 so as to be rotatable and movable in the x direction. The connection to the loading plate 15 is positioned on the positive side of the z direction and the positive side of the x direction with respect to the connection to the fixed part 13. An elastic force that opposes compression is generated. The interspring 29D is connected to the loading plate 15 and is connected to the spring shaft 27D via the slider 25D, and generates an elastic force that opposes displacement of the connection of the spring shaft 27D to the loading plate 15 to the positive side of the x direction.
従来技術、競合技術の概要(英語) BACKGROUND ART
As the elastic mechanism, for example, the constant force spring mechanism (for example Patent Document 1) are known. The constant force spring mechanism of the patent document 1, the spring constant of the spring having positive, negative spring constant of the spring mechanism, any elastic force thereof in the vertical direction is above the combined. Therefore, the spring force of the spring constant of the positive increases or decreases and, conversely, a negative spring constant decrease or increase the elastic force of the spring mechanism. As a result, the displacement in the vertical direction is kept constant irrespective of the size of the elastic force is generated in the upward direction becomes possible. In addition, a negative spring constant of the patent document 1 is a spring mechanism, a spring having a spring constant of the positive (the aforementioned positive spring having a spring constant of the spring is different.) And, the spring connected to the link mechanism which, by the change in the direction of the elastic force of the springs and linkages in the vertical direction by increasing or decreasing the component, this is realized by means of a spring constant.
