Abstract
Disclosed are devices and methods for reducing resonant vibrations in impact tools. The embodiments disclosed herein include the use of certain particles positioned within an impact tool, such as a drumstick, for converting the energy of vibration to heat energy resulting from collisions between the particles.
Claims15
A vibration-resistant drumstick comprising:
- a body portion having opposing first and second ends, the first end operable for striking a surface and the second end operable for being held by a user;
- and
- a plurality of particles in association with the instrument proximate at least one of the first and second ends, wherein the plurality of particles comprises a material having a density greater than the density of the body portion.
A module for reducing vibration in an impact tool, the module comprising:
- a container portion defining a hollow cavity for receiving particles;
- an attachment portion operable with the container portion for at least one of (1) attaching the module proximate an end of the impact tool and (2) securing the module within an end of the impact tool;
- and
- particles disposed within the hollow cavity, the particles occupying a volume less than a volume of the hollow cavity, and wherein the particles are capable of movement within the hollow cavity;
- wherein the particles comprise beads formed from about 99% mesh 20 copper powder.
2 more elements
A method for reducing vibration in an impact tool or instrument, the method comprising:
- procuring a module for reducing vibration in an impact tool or instrument, the module including particles having a density greater than the density of the material from which the impact tool or instrument is substantially formed, the module also having an attachment portion in coordination therewith;
- and
- attaching the module proximate an end of the impact tool or instrument via the attachment portion.
