Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved emergency vehicle proximity warning and communication system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the new and improved emergency vehicle proximity warning and communication system, is comprised of a plurality of components. Such components in their broadest context include a transmitter mechanism, a receiver mechanism, an emergency citizen band radio receiver, a vehicle radio, and a switch mechanism. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
More specifically, it will be noted that the system 10 of the present invention includes a transmitter housing 12 with a generally rectangular configuration. The transmitter housing has a top face, a bottom face, and a periphery formed therebetween thus defining an interior space. As shown in FIG. 5, the transmitter housing is situated within a grill 14 of an emergency vehicle 16. Ideally, the transmitter housing is constructed from a durable plastic. For reasons that will be set forth later, the emergency vehicle is further equipped with an emergency citizen band radio.
Situated in the transmitter housing is a transmitter mechanism 18. The transmitter mechanism is coupled to a siren of the emergency vehicle. In use, upon the activation of the siren of the vehicle, the transmitter mechanism is adapted to emit an activation signal about a predetermined distance via free space.
As shown in FIG. 4, a receiver housing 20 is provided having a planar bottom face, a short front face, and a tall rear face. The receiver housing further has a bevelled top face integrally formed between the rear face and the front face. The top face has a cloth mesh portion for allowing sound to travel therethrough. For mounting purposes, a pair of eyelets 22 are integrally formed on opposing side faces of the receiver housing in a plane in which the rear face resides. Working in conjunction with the eyelets is an adhesive 24 lining the rear. Preferably, the receiver housing is situated within a vehicle of the user on the dash board thereof.
For providing an indication that an emergency vehicle is in the proximity of the vehicle of the user, a receiver mechanism 26 is situated within the receiver housing. The receiver mechanism is adapted to actuate upon the receipt of the activation signal via free space.
To allow a driver of the emergency vehicle to communicate instructions to the user, a emergency citizen band radio receiver 28 is situated within the receiver housing. The emergency citizen band radio receiver is adapted to receive emergency instructions from the driver of the emergency vehicle upon the supply of power thereto. Preferably, the emergency citizen band radio is permanently tuned to channel "9" of the citizen frequency band. As such, the driver of the emergency vehicle is merely required to utilize a conventional citizen band radio transceiver to instruct another driver. The emergency citizen band radio receiver is further adapted to playback a prerecorded warning message contained therein upon the supply of power thereto in combination with the lack of receipt of emergency instructions from the driver of the emergency vehicle. The warning message preferably states the following: "An emergency vehicle is approaching. Please use caution while pulling to the right lane."
A vehicle radio 30 situated within the vehicle of the user is connected with the present invention. The vehicle radio is coupled to a plurality of standard speakers 32 for emitting radio signals therefrom upon the supply of power thereto. The speakers are further coupled to the emergency citizen band radio receiver for audibly transmitting the emergency instructions and the prerecorded warning message. It should be noted that, as an option, an additional speaker may be included within the receiver housing so as to require coupling of components of the receiver housing with solely the vehicle radio and a power source. In such an embodiment, the additional speaker is situated adjacent the mesh portion of the receiver housing.
Finally, a switch mechanism 34 is situated within the receiver housing for actuating the emergency citizen band radio receiver and the vehicle radio under the correct conditions. To accomplish this, the switch mechanism is coupled to the receiver mechanism, emergency citizen band radio receiver, and vehicle radio. In operation, the switch mechanism is adapted to allow the supply of power to the radio and further preclude the supply of power to the emergency citizen band radio receiver upon the lack of actuation of the receiver mechanism. Upon the actuation of the receiver mechanism, the switch mechanism is adapted to preclude the supply of power to the radio and further allow the supply of power to the emergency citizen band radio receiver.
As shown in FIG. 2, circuitry 36 is provided for affording proper operation of the foregoing components. Such circuitry ideally resides within the receiver housing. A first relay coil 38 and a receiver relay contact 40 are coupled between a positive terminal 42 and negative terminal 44 of a battery of the vehicle of the user. The first relay coil and receiver relay contact combination are coupled in parallel with the receiver mechanism, whereby the receiver relay contact has an closed orientation only upon the actuation of the receiver. Further provided is a first relay contact 48 connected in series with the switch mechanism. The combination of the first relay contact and the switch mechanism is also coupled in parallel with the receiver. The first relay contact has a closed orientation only upon the energization of the first relay coil which is actuated by the closing of the receiver relay contact. Connected in series with the radio is a first switch relay contact 50 which closes only when the switch mechanism is not in receipt of power which is afforded by the lack of receipt of the activation signal by the receiver. It should be noted that the combination of the radio and first switch relay contact is coupled in parallel with the receiver. A second switch relay contact 52 is connected in series with the emergency citizen band radio receiver between the positive and negative terminal of the battery. The second switch relay contact is adapted to close only upon the receipt of power by the switch mechanism. As such, by the above structure, the radio is only supplied power upon the lack of receipt of the activation signal by the receiver and the emergency citizen band radio receiver is only supplied power upon the receipt of the activation signal by the receiver.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
