ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to signaling devices and more particularly to signaling devices configured to retain elements, such as doors, windows, wheels, or the like, in a particular position, and to emit visual and/or audible signals.
2. Description of the Related Art
Emergency service personnel such as firefighters, policeman, etc., are often confronted with unpredictable situations, such as residential and commercial fires, elevator emergencies, car fires, lockouts, vehicle extrication's, etc. Many situations require the stabilization and securing of devices such as doors, windows, elevators, voids, or the like. Typically, elements like door wedges are used to secure doors and windows in an open position. However, during emergency situations, the environment may be dark or smoky and doors that have been secured in an open position by a door wedge may be difficult to locate. In addition, a door wedge is one of a number of tools that emergency service personnel may be required to carry, and can result in inefficient use of time due to searching time required to locate a particular tool. Therefore, a need exists for a signaling retention device configured to retain devices in a particular position and to emit visual and/or audible signals.
