摘要： A vibration mechanism having a magnetic spring includes a lower frame, an upper frame vertically movably mounted on the lower frame via a plurality of link mechanisms, and at least two permanent magnets mounted on the lower frame and the upper frame, respectively, with the same magnetic poles opposed to each other. A plurality of springs are connected to the link mechanisms to produce a lifting force of the upper frame. The total spring constant of the permanent magnets and the springs is partially set to a negative value or substantially zero.

摘要： A suspension unit includes a lower frame, an upper frame vertically movably mounted on the lower frame, and two link mechanisms disposed on respective sides of the upper and lower frames for connecting them to each other. Each of the two link mechanisms includes a parallel link mechanism having two arms extending generally parallel to each other and a pantograph-shaped link mechanism having a plurality of arms. The suspension unit further includes two permanent magnets each fixedly mounted on one of the upper and lower frames with like magnetic poles opposed to each other, a metallic spring engaged with one of the pantograph-shaped link mechanisms, and a shock absorber engaged with the other of the pantograph-shaped link mechanisms that has spring properties. With such construction, vibration below a predetermined amplitude is absorbed by the spring properties of the other of the pantograph-shaped link mechanisms with the shock absorber not operated.
摘要翻译：悬架单元包括下框架，上框架可垂直移动地安装在下框架上，以及两个连杆机构，设置在上框架和下框架的相应侧面上，用于将它们彼此连接。两个连杆机构中的每一个包括具有彼此平行延伸的两个臂的平行连杆机构和具有多个臂的缩放弓形连杆机构。悬挂单元还包括两个永磁体，每个永磁体固定地安装在上框架和下框架中的一个上，具有彼此相对的相似的磁极，金属弹簧与其中一个缩放弓形连杆机构接合，以及与另一个接合的减振器具有弹簧特性的受电弓形连杆机构。通过这种结构，低于预定幅度的振动被另一个受电弓形连杆机构的弹簧特性吸收，而减震器不工作。

摘要： A seat or bed partly includes frames 8, 14 and net-shaped skins 10, 16 held by the frames 8, 14 under tension, respectively. Each of the net-shaped skins 10, 16 is made of an upper mesh layer 24, a lower mesh layer 26, and a pile layer having a large number of piles 28 that connect the upper and lower mesh layers 24, 26 to each other. Each pile 28 is made of a single string.
摘要翻译：座椅或床部分地包括框架8,14和分别由张紧的框架8,14保持的网状表皮10,16。每个网状表面10,16由上网眼层24，下网眼层26和具有大量的桩28的绒头层制成，桩26将上下网格层24,26彼此连接。每个桩28由单根绳制成。
