Abstract
Abstract An air vent which comprises a casing in which a housing having a throughway is rotatably mounted about an axis extending across the casing. Spaced fixed vanes extend across the throughway parallel to the axis of rotation and further vanes extend transversely to the fixed vanes and are rotatably mounted on the fixed vanes. A control member is drivably connected to the further vanes so that movement of the member in one plane pivots the further vanes and in a transverse plane pivots the housing to vary the direction of egress of air from the casing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
An air vent comprising a casing having a bore, a housing pivotally mounted in the bore about an axis extending across the bore, a throughway in the housing, a number of spaced vanes fixed to the housing in the throughway and extending parallel to the housing axis, a number of further spaced vanes extending transversely to the fixed vanes and rotatably mounted about axes extending transverse to the housing axis, adjustable valve means located in the casing upstream of the housing for controlling the volume of air flow along the passageway, a manually operable control member, means to mount the control member for both universal movement on the casing and rotation about the longitudinal axis of the member, means to drivably connect the control member to the further vanes so that swinging of the control member in one plane rotates the further vanes and swinging of the control member in a transverse plane rotates the housing and means for drivably connecting the control member to the adjustable valve means so that rotation of the control member about its longitudinal axis effects adjustment of the valve means.
Claim 2
Dependent Claim
186 words
An air vent comprising a casing having a bore, a housing pivotally mounted in the bore about an axis extending across the bore, a throughway in the housing, a number of spaced vanes fixed to the housing in the throughway and extending parallel to the housing axis, a number of further spaced vanes extending transversely to the fixed vanes and rotatably mounted about axes extending transverse to the housing axis, adjustable valve means located in the casing upstream of the housing for controlling the volume of air flow along the passageway, a manually operable control member, means to mount the control member for both universal movement on the casing and rotation about the longitudinal axis of the member, means to drivably connect the control member to the further vanes so that swinging of the control member in one plane rotates the further vanes and swinging of the control member in a transverse plane rotates the housing and means for drivably connecting the control member to the adjustable valve means so that rotation of the control member about its longitudinal axis effects adjustment of the valve means.
Claim 3
Dependent Claim
47 words
An air vent as claimed in claim 1 wherein the control membEr is universally mounted intermediate of its ends and is drivably connected to both the further vanes and the adjustable valve means on the opposite side of the universal mounting to that which is manually engaged.
Claim 4
Dependent Claim
46 words
An air vent as claimed in claim 1 wherein said means to mount the manually operable control member for universal movement comprise a part-spherical housing mounted in a wall of the casing to one side of the bore and a part-spherical bearing on the control member.
Claim 5
Dependent Claim
19 words
An air vent as claimed in claim 1 wherein the further vanes are pivotally mounted on the fixed vanes.
Claim 6
Dependent Claim
67 words
An air vent as claimed in claim 1 wherein the driving connection between the control member and the adjustable valve means comprises a shaft connected by a universal joint to one end of the control member and universally mounted at its other end on the casing, the shaft carrying a gear which meshes with a gear on a further shaft which effects adjustment of the valve means.
Claim 7
Dependent Claim
21 words
An air vent as claimed in claim 5 wherein the valve means comprise a butterfly valve formed on said further shaft.
Claim 8
Dependent Claim
81 words
An air vent as claimed in claim 5 wherein the further shaft has an axially slidable driving connection with said valve means and spring means are provided between the driving connection and the valve means to urge the further shaft in a direction to maintain the gear on the further shaft in mesh with the gear on the first mentioned shaft so that the gears remain in mesh when the manually operable control member is swung to different positions of adjustment.
Claim 9
Dependent Claim
26 words
An air vent as claimed in claim 1 wherein the bore in the casing is generally rectangular in cross section and the housing is correspondingly contoured.
Claim 10
Dependent Claim
38 words
An air vent as claimed in claim 8 wherein the fixed vanes extend in the direction of the major direction of the bore and the further vanes extend in the direction of the minor direction of the bore.
