| Title: | Passive vibration reducing apparatus | Authors: | Jing, X | Issue Date: | 9-Jun-2020 | Source: | US Patent 10,675,743 B2. Washington, DC: US Patent and Trademark Office, 2020. | Abstract: | In an aspect of the disclosure there is provided a vibration reducing apparatus for a percussive tool having an axis of reciprocation. The apparatus comprises, a guide frame and at least one member extending across the axis of reciprocation. An assembly extending in a direction of along the axis of reciprocation comprises at least two layers and each layer comprises four interconnected elongate members pivotally attached and rotatable with respect to each other to define a polygon; and the assembly has at least one biasing means. A handle is movably coupled to the guide frame and supported on the assembly. The apparatus provides decreasing stiffness with increasing compression of the assembly under an applied load to the handle for reducing vibration in a predetermined frequency range. | Rights: | Assignee: The Hong Kong Polytechnic University. |
