Description
BACKGROUND OF THE INVENTION
The present invention relates to a ventilating arrangement for a car, and a car provided with such arrangement.
Modern cars have been provided with air conditioning systems in an attempt to properly ventilate the interior of the cars. While the known air conditioning systems achieve certain results, they also possess some disadvantages. Since modern cars are relatively tight the stale air inside the car is not immediately forced out, so that the incoming air just increases the pressure in the interior of the car body. In connection with this, separate ventilating systems have been proposed for a separate ventilating of the car interior. The known systems do not provide detection of carbon monoxide and its immediate evacuation from the interior of the car. It is well known that carbon monoxide from the car exhaust system is a frequent cause of poisoning of car occupants, sometimes with grave consequences.
SUBSTITUTE SHEET The existing systems also do not have a desired degree of simplicity, for example for their simple and convenient mounting in the interior of the car. Also, they do not have signaling devices which alert a car occupant to air contamination inside the car, to take immediate measures for its elimination. It is to be understood that the ventilating systems for cars can be further improved in the above specified aspects.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a ventilating system for a car, which is a further improvement of existing ventilating systems.

SUBSTITUTESHEET In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a ventilating system which has an exhaust fan δ inside a car, and a tube extending from the exhaust fan outwardly to evacuate air from the interior of the car, wherein a carbon monoxide detector is provided to detect the presence of carbon monoxide in the car to turn on the exhaust fan for its 0 evacuation.
When the ventilating system is designed in accordance with the present invention, it avoids the disadvantages of the prior art.
In accordance with another very important δ feature of the present invention, the system is provided with visual signal or audio signal indicators which produce respective signals in the event if carbon monoxide is present in the air inside the car, so that a car occupant becomes immediately 0 alerted to this fact and can turn on the exhaust fan by a manual switch. This guarantees that in the event of some malfunctions on the line between the and exhaust fan, the presence of carbon monoxide will
SUBSTITUTE SHEET not be undetected and not taken care of.
Still a further important feature of the present invention is that the exhaust fan, the tubes, and the detector can together form a unit which is jointly δ removable from and mountable in the car. This permits a user to purchase such a unit and to install it in his existing car in a simple manner.
The novel features of the present invention are set orth in particular in the appended claims. The 0 invention itself, both as to its construction and its manner of operation will be best understood from the following description of preferred embodiments, which is accompanied by the following drawings.

DESCRIPTION OF PREFERRED EMBODIMENTS
A ventilating arrangement in accordance with the present invention is provided in a car which is identified as a whole with reference numeral 1. The
SUBSTITUTE SHEET ventilating arrangement includes an exhaust fan 2 which is located inside a car body 3 in a central region of its roof 4. The exhaust fan 2 has a well known construction and therefore not described in δ detail.
A defective air is aspirated by the exhaust fan from the interior of the car and forced through a tube system outwardly of the car. in the embodiment of FIGS. 1 and 2, the tube system includes a single
10 tube δ which has a front end connected with an outlet or pressure side of the exhaust fan 2. The tube δ extends toward a rear window 6 of the car and has an outlet end which opens outwardly of the car in this region. Therefore the defective air is evacuated lδ from the interior of the car outwardly, during the operation of the exhaust fan, through the outlet end
7.
In accordance with the embodiment of FIG. 3, which illustrates a ventilating system for a car of 20 sports model, the tube system includes a central tube
8 which extends from the exhaust fan rearwardly, and two branching tubes which extend from the rear end of the central tube 8. The branching tubes which
SUBSTITUTESHEET are identified with reference numeral 9 are located in the region between the rear window 6 and a respective one of the side windows 11, to expel the defective air in these regions during the operation δ of the exhaust fan 2.
The exhaust fan is provided with a power source. In accordance with an advantageous feature of the present invention, the power source which is identified with reference numeral 12 in FIG. 4 is 0 separate from other power systems of the car it can be formed, for example, as a battery. In this case the exhaust fan can operate even when other systems of the car are turned off, on the other hand, it is to be understood that the exhaust fan can be δ connected with the power systems of the car, if so desired .
The exhaust fan and intake system is further provided with a circular rotatable cover having a plurality of triangular pie shaped holes located through the cover lδ having corresponding to a disc 16 having corresponding* pie shaped holes, such that the pie shaped holes of the cover and the disc may be fully aligned in an open position or partially
SUBSTITUTE SHEET aligned to adjust the amount of the incoming air into the system. The round cover rotates so that the surface area of the opening holes may be increased or decreased manually as the cover is rotated clockwise δ or counter clockwise. As a safety device, the holes may be screened to prevent the insertion of children' s ingers.
The ventilating system is further provided with means for sensing a defective air. The sensing means 0 includes a carbon monoxide detector which is identified with reference numeral 13. When the detector 13 senses the presence of carbon monoxide above a respective level, it immediately turns on the exhaust fan 2, which starts operating and evacuates δ the defective air with carbon monoxide from the interior of the car. The sensing means also includes a smoke detector 23 or another detector which can be utilized for sensing the defective air. It is also connected with the exhaust fan 2 and activates it 0 when respective impurities are sensed in the air inside the car by this detector or detectors.
The ventilating system of the present invention is also provided with a manual switch 14 which is
SUBSTITUTE SHEET actuated manually by a user or car occupant at will.
In many instances, for example when a car passes areas with bad smell and the outside air penetrates into the car, the automatic sensor does not detect δ air deficiency and it is not desired to use the air conditioning system since it will draw- the outside air into the car. However, a car occupant feels very uncomfortable, breathing in the thus contaminated air. in this case, the user turns on the manual 0 switch 14 and activates the exhaust fan for evacuating the contaminated air from the interior of the car. The provision of both the automatic system and the manual system of ventilation makes the inventive ventilating arrangement more universal and δ practical. Additional safety measures can be taken in accordance with the present invention to make sure that even in the event of malfunction of automatic ventilation system, carbon monoxide contamination is prevented in accordance with the present invention, 0 the carbon monoxide detector is connected with a visual signal indicator 17 which can be formed as a signal lamp if the line between the detector 13 and the exhaust fan 2 becomes inoperative for any reason,
SUBSTITUTE SHEET the signal lamp 17 will emit signal light since it is activated by the carbon monoxide detector 13. When the car occupant sees the warning signal of the signal lamp 17, it actuates the manual switch 14 and thereby activates the exhaust fan. Instead of or in addition to the signal lamp 17, an audio signal indicator 18 formed as a speaker can be provided and also connected with the detector 13 to produce the audio warning to the car occupant about the presence of carbon monoxide. When the car occupant hears the warning, he or she turns on the exhaust fan 2 by the manual switch, to evacuate the defective air from the interior of the car.
FIG. 8 shows an embodiment in which the exhaust fan 2, the tube, and the carbon monoxide detector 13 together form a unit which is insertable and mountable as a whole in a car. The outlet end of the tube is somewhat bent upwardly so as to be easily extended through the car roof outwardly of the car.
In FIG. 9 the exhaust fan 2, the tube, the carbon monoxide detector 13 and the smoke detector 23 together form a unit which is insertable and mountable as a whole in the car. The constructions
SUBSTITUTE SHEET of FIGS. 8 and 9 are very easy 3δ to install in existing cars with only insignificant mounting works for attaching the above described units to the car roof.
δ The removable mounted unit comprises the channel or tube having a tube which has a downwardly extending flange for the introduction of exhaust air and a connecting tube having detector means located on the bottom side of said connecting means and said 0 connecting tube extending rearwardly and then upwardly out to expel the exhaust air.
As also shown in FIG. 9 fan 2 is connected electrically to detectors 13 and 23 by means of wires 24, 2δ and 26. Bracket means 27 and 28 are attached δ to the 10 inner surface 29 of the roof of vehicle 1. The unit exits through the upper, outer roof section 30 of vehicle 1 in space 31 of the roof of said vehicle. In another embodiment for sports models, the outlet end of the tube means may be constructed 0 so as to exit not upwardly, but outwardly to the side through the vertical portion of the roof of car 1.
