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.
Claims8
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.
