Abstract
The deployable stop sign for use with a traffic light during power loss comprises an enclosure, a traffic sign, a weight, a pair of electromagnets, and a sign retractor. The deployable stop sign for use with a traffic light during power loss may be coupled to a span wire or other structure supporting one or more traffic signals. A loss of power may deploy the traffic sign by deenergizing the pair of electromagnets and releasing the weight which may pull the traffic sign out of the enclosure. A restoration of power may energize the sign retractor to pull the traffic sign back into the enclosure and may energize the pair of electromagnets to hold the traffic sign within the enclosure.
Claims18
A deployable stop sign for use with a traffic light during power loss comprising:
- an enclosure, a traffic sign, a weight, a pair of electromagnets, and a sign retractor;
- wherein the deployable stop sign for use with a traffic light during power loss is coupled to a span wire or other structure supporting one or more traffic signals;
- wherein a loss of power deploys the traffic sign by deenergizing the pair of electromagnets and releasing the weight which pulls the traffic sign out of the enclosure;
- wherein a restoration of power energizes the sign retractor to pull the traffic sign back into the enclosure and energizes the pair of electromagnets to hold the traffic sign within the enclosure;
- wherein the enclosure comprises two side walls, a front wall, a rear wall, and a top wall;
- wherein the enclosure houses the traffic sign, a motor, and an axle;
- wherein the enclosure comprises a bottom aperture through which the traffic sign is deployed and retracted;
- wherein the top wall comprises one or more mounting couplers which couple the enclosure to the span wire or to the other structure supporting the one or more traffic signals.
