BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to garage door openers and more particularly pertains to a new CARBON MONOXIDE SENSOR for preventing carbon monoxide emitted by a vehicle from causing a fatality.

2. Description of the Prior Art

The use of garage door openers is known in the prior art. More specifically, garage door openers heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

Known prior art garage door openers include U.S. Pat. No. 4,819,551; U.S. Pat. No. 4,338,526; U.S. Pat. No. 4,197,675; U.S. Pat. No. 4,257,675; U.S. Pat. No. 4,257,319; and U.S. Pat. No. 4,007,456; and U.S. Pat. No. 4,360,801.

In these respects, the CARBON MONOXIDE SENSOR according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of preventing carbon monoxide emitted by a vehicle from causing a fatality.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of garage door openers now present in the prior art, the present invention provides a new CARBON MONOXIDE SENSOR construction wherein the same can be utilized for preventing carbon monoxide emitted by a vehicle from causing a fatality.

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new CARBON MONOXIDE SENSOR apparatus and method which has many of the advantages of the garage door openers mentioned heretofore and many novel features that result in a new CARBON MONOXIDE SENSOR which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art garage door openers, either alone or in any combination thereof.

To attain this, the present invention generally comprises a garage having an automatic door adapted to open only upon the receipt of an activation signal. Further provided is a carbon monoxide sensor positioned within the garage for transmitting the activation signal upon the detection of an amount of carbon monoxide which exceeds a predetermined amount. Also positioned within the garage is a plurality of exhaust fans connected to the carbon monoxide sensor. Each exhaust fan is adapted to expel contaminated air from the garage only when the activation signal is received from the carbon monoxide sensor. For detecting the presence of a vehicle within the garage, a light beam transmitter is situated on a first side wall of the garage. In use, the light beam transmitter adapted for continuously transmitting a beam of light toward a second side wall of the garage. Associated therewith is a light beam receiver situated on the second side wall of the garage directly across from the light beam transmitter. The light beam receiver is adapted to transmit the activation signal only upon the lack of receipt of the light beam as in the case where a vehicle is present. As shown in FIG. 3, a switch is included having a first contact connected to a voltage source adapted to continuously transmit the activation signal A second contact of the switch is connected to the light beam receiver. The switch further has a third contact connected with the first contact in a first orientation and connected with the second contact in a second orientation. In use, the switch may be manually transferred between the first and second orientation thereof. With reference still to FIG. 3, an AND gate is shown having a first input connected to the carbon monoxide sensor and a second input connected to the third contact of the switch. An output of the AND gate is connected to the automatic door of the garage.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

FIG. 1 is a side view of a new CARBON MONOXIDE SENSOR according to the present invention.

FIG. 2 is a top view of the present invention.

FIG. 3 is a schematic diagram of the various electrical components of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, a new CARBON MONOXIDE SENSOR embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The system 10 of the present invention includes garage having an automatic door 12 adapted to open only upon the receipt of an activation signal.

Further provided is a carbon monoxide sensor 14 positioned within the garage for transmitting the activation signal upon the detection of an amount of carbon monoxide which exceeds a predetermined amount.

Also positioned within the garage is a plurality of exhaust fans 16 connected to the carbon monoxide sensor. Each exhaust fan is adapted to expel contaminated air from the garage only when the activation signal is received from the carbon monoxide sensor. In the present description, it should be noted that the activation signal comprises a voltage pulse. As shown in FIG. 3, the automatic door of the garage and the exhaust fans are actuated by way of a voltage controlled switch to ensure that a proper voltage is supplied thereto.

For detecting the presence of a vehicle within the garage, a light beam transmitter 18 is situated on a first side wall of the garage. In use, the light beam transmitter adapted for continuously transmitting a beam of light toward a second side wall of the garage. Associated therewith is a light beam receiver 20 situated on the second side wall of the garage directly across from the light beam transmitter. The light beam receiver is adapted to transmit the activation signal only upon the lack of receipt of the light beam as in the case where a vehicle is present. It should be noted that in another embodiment, the transmitter and receiver are situated adjacent each other and utilize a reflector to transmit a light beam therebetween.

As shown in FIG. 3, a switch 22 is included having a first contact 24 connected to a voltage source adapted to continuously transmit the activation signal A second contact 26 of the switch is connected to the light beam receiver. The switch further has a third contact 28 connected with the first contact in a first orientation and connected with the second contact in a second orientation. In use, the switch may be manually transferred between the first and second orientation thereof. In the preferred embodiment, the switch and the remaining components with the exception of the light source are situated on and within a housing 29. Note FIGS. 1 & 2.

With reference still to FIG. 3, an AND gate 30 is shown having a first input connected to the carbon monoxide sensor and a second input connected to the third contact of the switch. An output of the AND gate is connected to the automatic door of the garage. Connected between the AND gate and the automatic door is a one shot multivibrator 31 adapted to transmit the activation signal for a predetermined amount of time corresponding to that which it takes to open the door.

In use, the exhaust fans expel contaminated air unconditionally upon the detection of carbon monoxide by the carbon monoxide sensor. In a first mode of operation, the automatic door opens unconditionally upon the detection of carbon monoxide by the carbon monoxide sensor. In a second mode of operation, the automatic door of the garage opens only when the vehicle is present and the carbon monoxide sensor has detected carbon. The second mode of operation thus prevents the opening of the door when the vehicle is not present.

As to a further discussion of 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.
