Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
In a device wherein a current of air flows through a passageway and exits at an outlet thereof, an air distributor mounted in said outlet for controlling the direction of flow of the air current, said distributor comprising a rotor element extending across said passageway outlet and disposed for rotation relative thereto about a longitudinal axis, a plurality of axially spaced apart vanes mounted on said rotor element in transeverse relation to the longitudinal axis thereof, and a plurality of angularly spaced apart vanes mounted on said rotor element in radially extending relation to said longitudinal axis, said axially spaced transverse vanes each having a central portion connected to the rotor element and disposed generally perpendicular thereto, and a pair of opposite outer portions extending from said central portion and inclined at an acute angle with respect to the rotor element.
Claim 2
Dependent Claim
141 words
In a device wherein a current of air flows through a passageway and exits at an outlet thereof, an air distributor mounted in said outlet for controlling the direction of flow of the air current, said distributor comprising a rotor element extending across said passageway outlet and disposed for rotation relative thereto about a longitudinal axis, a plurality of axially spaced apart vanes mounted on said rotor element in transeverse relation to the longitudinal axis thereof, and a plurality of angularly spaced apart vanes mounted on said rotor element in radially extending relation to said longitudinal axis, said axially spaced transverse vanes each having a central portion connected to the rotor element and disposed generally perpendicular thereto, and a pair of opposite outer portions extending from said central portion and inclined at an acute angle with respect to the rotor element.
Claim 3
Dependent Claim
23 words
An air distributor according to claim 1 wherein said angularly spaced radial vanes are disposed at an acute angle relative to each other.
Claim 4
Dependent Claim
