Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
75 words
An air vent device for controlling a stream of air comprising: a flexible blade mounted for deflection and having a plurality of apertures therein, a plurality of deflectors fixed to the blade for movement in unison therewith in direct response to the deflection thereof, and means for controlling the deflection of the blade and thereby the position of the deflectors for effecting the convergence and divergence of a stream of air passing through the apertures.
Claim 2
Dependent Claim
75 words
An air vent device for controlling a stream of air comprising: a flexible blade mounted for deflection and having a plurality of apertures therein, a plurality of deflectors fixed to the blade for movement in unison therewith in direct response to the deflection thereof, and means for controlling the deflection of the blade and thereby the position of the deflectors for effecting the convergence and divergence of a stream of air passing through the apertures.
Claim 3
Dependent Claim
75 words
An air vent device for controlling a stream of air comprising: a flexible blade mounted for deflection and having a plurality of apertures therein, a plurality of deflectors fixed to the blade for movement in unison therewith in direct response to the deflection thereof, and means for controlling the deflection of the blade and thereby the position of the deflectors for effecting the convergence and divergence of a stream of air passing through the apertures.
Claim 4
Dependent Claim
75 words
An air vent device for controlling a stream of air comprising: a flexible blade mounted for deflection and having a plurality of apertures therein, a plurality of deflectors fixed to the blade for movement in unison therewith in direct response to the deflection thereof, and means for controlling the deflection of the blade and thereby the position of the deflectors for effecting the convergence and divergence of a stream of air passing through the apertures.
Claim 5
Dependent Claim
81 words
An air vent device as claimed in claim 1, wherein the deflectors are mounted on the blade so that for a given degree of deflection of the blade in one direction there is corresponding angular movement of the deflectors relative to their normal position and that for the same degree of deflection in the opposite direction the angular displacement of the deflectors is equal aNd opposite the angular movement of the deflectors responsive to the deflection in the said one direction.
Claim 6
Dependent Claim
30 words
The vent device as claimed in claim 1, further comprising means for controlling the position of the blade including said first and second positions and a range of positions therebetween.
Claim 7
Dependent Claim
86 words
A vent device for converging and diverging a stream of fluid, comprising a flexible blade member mounted for deflection in a direction transverse of its length, a plurality of substantially planar deflectors fixed to the blade member, said blade member having an area and contour between adjacent deflectors for permitting fluid to flow between the deflectors in about the deflection direction of said blade member, and said blade is mounted in a housing wherein a control vane is disposed in the housing upstream of the blade.
Claim 8
Dependent Claim
86 words
A vent device for converging and diverging a stream of fluid, comprising a flexible blade member mounted for deflection in a direction transverse of its length, a plurality of substantially planar deflectors fixed to the blade member, said blade member having an area and contour between adjacent deflectors for permitting fluid to flow between the deflectors in about the deflection direction of said blade member, and said blade is mounted in a housing wherein a control vane is disposed in the housing upstream of the blade.
Claim 9
Dependent Claim
44 words
The vent device as claimed in claim 4, wherein the ends of the blade are slidably mounted in the housing, and wherein the blade includes a pin mounted for displacement in a slot provided in the housing for guiding the movement of the blade.
Claim 10
Dependent Claim
36 words
The vent device as claimed in claim 4, wherein one of the ends of the blade is pivotally mounted in the housing and the other end is movably mounted relative to said one of the ends.
