Abstract:
A foot device for supporting an electronic equipment on a supporting plane, the device comprising:(a) a sleeve having an axial hole which extends therethrough to a top end and a bottom end of the sleeve;(b) a plurality of balls disposed in the axial hole, whereby any two adjacent balls are in an engagement with each other through a contact point, a topmost ball extending beyond the top end of the axial hole and a bottommost ball extending beyond the bottom end of the axial hole;(c) a cap disposed above the top end of the axial hole and in contact with the topmost ball for engagement by the electronic equipment, and a base disposed under the bottom end of the axial hole and in contact with the bottommost ball for engagement with the supporting plane;(d) each of the cap and base including a recess formed therein, an air opening formed in a periphery of each of the cap and base for providing communication between the recesses and outside air to balance air pressures in the recesses; and(e) whereby the device permits supporting the electronic equipment in a suspended manner and out of contact with the supporting plane so that vibrations generated by the electronic equipment is not absorbed by the supporting plane, thereby resulting in a uniform transmission of the vibrations in all directions without damping or interference.
