Definitions

  • ABSTRACT An air vent device for use in any type of air conditioning systems, in particular that of a motor vehicle employing a stream of air, including a flexible blade mounted for deflection of the air stream, apertures therein through which the stream of air passes and a plurality of fins or tubular deflectors extending generally perpendicular to the blade.
  • the combination is preferably formed as a single body of moulded plastic or of metal.
  • the air vent can be adjusted to various positions for converging and diverging the stream of air, a given deflection producing a certain degree of divergence or convergence of the deflectors.
  • Means for mounting the air vent includes freely and slidably mounting the ends with a guiding slot and pin arrangement therebetween, and freely mounting one end for movement and the other end for pivoting.
  • the present invention relates to an air vent device for air conditioning systems in particular for use as outlet air vents for ventilating systems, forced or natural air or heating systems; passengers compartment for vehicles in particular motor vehicles; living premises or the like provided with built-in or portable systems (blown air heating systems, refrigeration systems, air conditioning systems, ventilation systems, etc...); and other devices such as hair dryers.
  • the present invention is an improvement of the device disclosed in the U.S. Pat. application Ser. No., 6.715 filed on Jan. 29, 1970, now U.S. Pat. No. 3,648,590 and issued 3/14/72, for improvements in the vent devices for vehicle air conditioning systems.
  • An object of thepresent invention as well as that of the above-mentioned patent application is a device for either concentrating or diffusing a stream of air as well as the entire range of operation therebetween.
  • a further object of such a device is a simple industrial construction.
  • known prior art devices do not enable the concentration and diffusion of a stream of air by the same device at the will of the user.
  • Devices are known in which the air vent only converges a stream of air.
  • Other devices are known which diverge a stream of air.
  • still other devices enable the variation of the orientation of the stream of air by means of a swivelling vane or a certain number of juxtaposed fins which are always maintained parallel to one another.
  • the device according to the present invention comprises a combination of vanes or fins that are simultaneously controlled to converge or diverge a stream of air.
  • the device according to the present invention includes additional features described hereinbelow.
  • Curved or straight fin or tube deflectors are rigidly fixed on or preferably integrally formed with a flexible blade which permits the flow ofa stream of air.
  • Each fin or tube is arranged a the same angle, at its point of connection with the flexible blade, relative to the line normal to the median line of the blade at this point.
  • the blade support is flexed in such a manner that the concavity is the same side along its entire useful length, the convergence, for example, of the combination of the fins will be increased. In flexing the same support blade in the opposite direction, the divergence of the fins will thus be increased.
  • FIG. 1a shows a flexible blade with parallel fins for providing a parallel stream of air
  • FIG. lb shows a flexible blade for providing a converging stream of air
  • FIG. shows a flexible blade for providing a diverging stream of air
  • FIG. 2 shows an exploded view of an embodiment of a case with a flexible fin carrier according to the invention
  • FIG. 3 shows an embodiment in which a flexible blade supports tube deflectors
  • FIGS. 4a and 4b show the normal and the flexed position respectively of a blade carrying fins having different lengths for aesthetic reasons;
  • FIGS. 5a, 5b, 5c and 5d show an alternative embodiment in which the fins are not secured perpendicular to the flexible blade, but displaced a certain number of degrees therefrom;
  • FIGS. 6 and 7 show various modifications of the flexible blade and the fins
  • FIGS. 8 and 9 show two examples of maintaining and guiding the flexible blade in the housing
  • FIGS. 10 and 11 show two possible industrial embodiments of the blade and the fins in which the device of FIG. 10 is moulded of plastics material and the device of FIG. 11 is formed by cutting out and bending a metal blade.
  • the characteristics of the air vent device according to the invention comprise a flexible blade 1 carrying fins 2 enabling air to pass through the spaces between the blade and the fins.
  • the flexible blade in FIG. la is, in its normal non-flexed position, thereby yielding a parallel stream of air.
  • the blade In the position shown in FIG. lb, the blade is flexed in a direction in order to converge the stream of air whereas in the position shown in FIG. lb the blade is flexed in the opposite direction for obtaining a divergent stream of air.
  • the flexible blade 4 includes apertures 5 for passing the air through the blade and between the fins 6.
  • a vane 7 is disposed upstream of the blade for adjusting the rate of flow of the stream of air.
  • the device for controlling the deformation of the flexible blade is not shown in the embodiment of FIG. 2.
  • the adjustment of the rate of flow of the stream air can be assured by any known type of vane controlled independently of or responsive to means for controlling the deflection of the blade and mounted on the housing, the cover 3' or at any other point along its associated air duct.
  • the flexible blade 4 carriers deflector tubes 8 aligned with the apertures 5 in the blade. Additional air passages 9 could also be provided in the blade 4.
  • FIGS. 4a, 4b and 5a, 5b, 5c, 5d show flexible blades with fins differing in their length, and their connection with their respective blades.
  • the fins are of different lengths and arranged in such a manner that when the blade is in its flexed position as shown in FIG. 4b to assure the maximum divergence, the free ends of the fins are aligned either along a straight line or curved line for aesthetic reasons.
  • FIG. 5a shows the normal position of the blade with non-parallel blades arranged thereon.
  • FIG. 5b shows the position in which the fins are parallel when the blade is flexed (this position shows the shape in which the blades and the fins could be moulded in one piece).
  • FIG. Sc shows the maximum converging position in which the fin at the far left is deflected through an angle A corresponding to a deflection F of the blade.
  • FIG. 5d shows the maximum diverging position in which the fin at the far left is deflected through an angle B corresponding to same value of deflection F.
  • FIGS. 6, 7 and show fins which extend beyond the two sides of the flexible blade.
  • the flexible blade 4 is located on the lower edge of the fins.
  • the blade is formed by two ribs 11 connected to the upper and lower edges respectively of the fins. This embodiment corresponds to the central portion of the embodiment of FIG. 10.
  • the blade 4 or the ribs 11 forming the blade can be reinforced or made more rigid by a metal wire (a piano string for example) or a metal blade inserted during molding or connected after moulding to the single body formed of plastics material.
  • the blade must be held and guided in the casing while at the same time being free to flex a certain degree.
  • the blade can, for example, be free to displace by a groove at its two ends and guided at its middle portion by a pin and slot means 10 (FIG. 8).
