Abstract
Abstract An air register of molded plastic material comprising a basic framework with slotted air openings, a pair of vanes journaled in the frame with means for opening and closing the vanes for the passage of a selected volume of air through the register; a pair of spur gears, one gear cast at an end of one vane and another integrally cast at an end of the other of said vanes, the gears being properly enmeshed for operation upon mounting the same to said framework and means for operating the gear train for movement of said vanes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
A molded plastic air register adapted to be mounted in a wall or floor opening, comprising: a frame member provided with an open gridwork for the passage of air therethrough and a continuous integrally molded strip about said gridwork extending from one side of said frame member, and a pair of vane members pivotally mounted on said frame member between opposing sides of said strip member by extensions integrally molded to said vane members to permit said vane members to move between positions providing a different restriction to the flow of air through said gridwork, said vane members including actuating means integrally molded therewith for moving said vane members between said positions, said actuating means including a gear integrally molded to the same end of each of said vane members, and an actuator integrally molded with one of said gears and extending into said gridwork to be actuated from the side of said frame opposite to that on which the vane members are mounted.
Claim 2
Dependent Claim
164 words
A molded plastic air register adapted to be mounted in a wall or floor opening, comprising: a frame member provided with an open gridwork for the passage of air therethrough and a continuous integrally molded strip about said gridwork extending from one side of said frame member, and a pair of vane members pivotally mounted on said frame member between opposing sides of said strip member by extensions integrally molded to said vane members to permit said vane members to move between positions providing a different restriction to the flow of air through said gridwork, said vane members including actuating means integrally molded therewith for moving said vane members between said positions, said actuating means including a gear integrally molded to the same end of each of said vane members, and an actuator integrally molded with one of said gears and extending into said gridwork to be actuated from the side of said frame opposite to that on which the vane members are mounted.
Claim 3
Dependent Claim
59 words
The air register of claim 1 wherein said actuator is formed on the side of said one of said spur gears facing the vane member that is integrally formed therewith, and the other vane member includes a slot adjacent the spur gear formed integrally therewith for receipt of said actuator as it is operated to move said vane members.
Claim 4
Dependent Claim
21 words
The air register of claim 1 wherein said vane members are mounted to move in an arcuate path in opposite directions.
Claim 5
Dependent Claim
22 words
The air register of claim 1 wherein said actuator extends to where it is substantially flush with the surface of said gridwork.
Claim 6
Dependent Claim
47 words
The air register of claim 1 further including stop means associated with said actuating means for providing interference to movement of said vane members between said positions whereby the vane members may be selectively positioned to provide a desired restriction to flow of air through said register.
Claim 7
Dependent Claim
56 words
The air register of claim 5 wherein said stop means includes spaced projections integrally molded with one of said actuating means and said frame, and an interference member integrally molded with the other of said actuating means and frame, said projections and interference member adapted to be in substantial interference during actuation of said actuating means.
Claim 8
Dependent Claim
17 words
The air register of claim 6 wherein said spaced projections are integrally molded with said actuating means.
Claim 9
Dependent Claim
162 words
An air register adapted to be mounted in a wall or floor opening, comprising: a frame member provided with an open gridwork for the passage of air therethrough and a continuous strip about said gridwork extending from one side of said frame member, and a pair of molded plastic vane members pivotally mounted on said frame member between opposing sides of said strip member by extensions integrally molded to said vane members to permit said vane members to move between positions providing a different restriction to the flow of air through said gridwork, said vane members including actuating means integrally molded therewith for moving said vane members between said positions, said actuating means including a gear integrally molded to the same end of each of said vane members, and an actuator integrally molded to one of said gears and extending into said gridwork to be actuated from the side of said frame opposite to that on which the vane members are mounted.
Claim 10
Dependent Claim
162 words
An air register adapted to be mounted in a wall or floor opening, comprising: a frame member provided with an open gridwork for the passage of air therethrough and a continuous strip about said gridwork extending from one side of said frame member, and a pair of molded plastic vane members pivotally mounted on said frame member between opposing sides of said strip member by extensions integrally molded to said vane members to permit said vane members to move between positions providing a different restriction to the flow of air through said gridwork, said vane members including actuating means integrally molded therewith for moving said vane members between said positions, said actuating means including a gear integrally molded to the same end of each of said vane members, and an actuator integrally molded to one of said gears and extending into said gridwork to be actuated from the side of said frame opposite to that on which the vane members are mounted.
