Switch lock mechanism
View Patent ↗A locking assembly for locking a switch is provided. According to a preferred embodiment, a locking member is connected to a support member having a plurality of first grooves, a lower receiving element, a retaining tab, a resilient member and a fastening element. Preferably, the lower receiving element includes a securing socket element having at least a second groove and a third groove. According to a preferred embodiment, the fastening element preferably secures the locking member, the lower receiving element, and the resilient member with a panel to form a locking assembly that automatically locks the switch when the switch is in a selected position.
1. A locking assembly for locking a switch attached to a panel having at least a first hole for allowing the switch to extend through the panel and a second hole, further wherein the switch is a rocker switch having a rocker member which is movable between an ON position and an OFF position, wherein the locking assembly comprises:
a locking member, wherein the locking member comprises a first section and a second section; wherein the first section is at a first height above the surface of the panel and the second section is at a second height above the surface of the panel; wherein the second height is greater than the first height; further wherein the second section is cantilevered over the rocker member when the switch is in an OFF position; further wherein the second section is not cantilevered over the rocker member when the switch is in an ON position;
a support member, wherein the support member is attached to the locking member at a substantially perpendicular angle; further wherein support member passes through the second hole in the panel; further wherein the support member further comprises at least one projection;
a lower receiving element, wherein the lower receiving element comprises: a securing socket comprised of at least one receiving groove; wherein the lower receiving element is located below the panel; further wherein the securing socket is configured to receive the supporting member; further wherein the at least one projection of the supporting member is inserted within the receiving groove of the lower receiving element; further wherein the lower receiving element preferably further includes at least a retaining tab and a spring groove;
a resilient member, wherein the resilient member comprises a center portion, a first end and a second end; wherein the securing socket passes through the center portion of the resilient member; further wherein the first end of the resilient member provides a sideways force to the retaining tab; further wherein the second end of the resilient member is located within the spring groove of the lower receiving element; and
a fastening element, wherein the fastening element is inserted through the lower receiving element and into the support member thereby securing the lower receiving element to the support member; wherein the resilient member is positioned between the lower receiving element and the support member;
wherein, when the switch is in the OFF position, the first and second ends of the resilient member provide a torsional force via the retaining tab and the spring groove to the lower receiving element so that the attached movable end of the locking member is cantilevered over the rocker member.
2. The apparatus of claim 1 , wherein the support member is cylindrical.
3. The apparatus of claim 2 , wherein the resilient member is a torsion spring.
4. The apparatus of claim 3 , wherein the fastening element is a screw.
5. The apparatus of claim 3 , wherein the fastening element is a pin.
6. The apparatus of claim 3 , wherein the resilient member is a helical torsion spring.
