Abstract
A multi-mode vibration absorbing device for implements includes a base member and a mass mounted to the base member and cantilevered relative thereto. The multi-mode vibration absorbing device is tuned such that it vibrates at the same frequency as the implement but out of phase therewith.
Claims13
A multi-mode vibration absorbing device for an implement comprising:
- a viscoelastic base member to be mounted at least partially within a handle of the implement and having a body and a projection extending from said body with an aperture extending therethrough;
- a mass extending through said aperture and directly supported by and cantilevered relative to said body, said device being tuned such that it vibrates at the same set of frequencies as the implement but out of phase therewith.
An implement comprising:
- a frame including a head and a handle;
- a vibration absorbing device mounted in said handle of said implement and including a viscoelastic base member having a body and a projection extending from said body with an aperture extending therethrough and a mass extending through said aperture and directly supported by and cantilevered relative to said body, said device being tuned such that it vibrates at the same frequency as said implement but out of phase therewith.
