BI-DIRECTIONAL TAMPER RESISTANT TEMPERATURE DIAL
Document Type and Number:
WIPO Patent Application WO2006057964
Kind Code:
B1
Abstract:
A bi-directional tamper resistant temperature adjustment controller interface comprises a control dial (104) having an interior face wherein a cylindrical center boss extends (204) therefrom, said cylindrical center boss having a substantially annular cross section, and a central axial bore (414) adapted to receive a rotatable control member and an exterior side wall of the boss has formed therein a first and a second ring of inline recessed notches (208) adapted for resistively engaging a deflecting member (210). In one embodiment of the invention the first and second ring of inline recessed notches are a first and second ring of directional serrations wherein the first ring of serrations are angularly directed in a first direction to resist rotation of the dial in one direction of rotation and the second ring of serrations are angularly directed in a second direction to resist rotation of the dial in an opposing direction of rotation.
