Title:
SHEET SUSPENSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/079942
Kind Code:
A1
Abstract:
The present invention improves vibration absorption properties and shock absorption properties. A sheet suspension mechanism (1) is configured such that an intermediate frame (300) is supported by a base frame (100) via a first link mechanism (130), and a sheet support frame (200) is supported by the intermediate frame (300) via a second link mechanism (230). A first spring mechanism (140) that elastically biases the intermediate frame (300) and a second spring mechanism (240) that elastically biases the sheet support frame (200) are provided, and a damper (150) bridges between the base frame (100) and the sheet support frame (200), excluding the intermediate frame (300). The phases, with respect to vibration, of the sheet support frame (200), on which the damping force of the damper (150) acts directly, and the intermediate frame (300), on which the properties of the damper (150) do not directly act, differ, and thus high vibration absorption properties and shock absorption properties can be exhibited.
