Abstract
Abstract An air conditioner louver construction which permits easy insertion of a control wheel into the frame of the louver by virtue of a unique approach, whereupon the control wheel is locked into place by a novel frame structure that permits rotation in each direction and positively prevents inadvertent dislocation of the control wheel from the louver frame, while also providing a reduced complexity and increased air volume in a louver construction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
An air flow louver unit, comprising: a. a main frame comprising a longitudinal stationary member, b. a plurality of vanes pivotally mounted in said main frame for directing air flow through said frame, c. said vanes including projecting axles having flanges at their outer ends adjacent their point of contact with said main frame for the purpose of preventing said axles from becoming detached from said main frame in the event said main frame is accidentally distorted, d. a control wheel having a partial peripheral ring attached to at least one of said vanes for controlling the direction of movement of all of said vanes, e. a pair of spaced apart side walls on said longitudinal member forming a control wheel housing, and f. a structure having a circular edge formed in each side wall in a manner to provide a bearing, supporting, and retaining surface for said peripheral ring.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
141 words
An air flow louver unit, comprising: a. a main frame comprising a stationary member, b. a plurality of vanes pivotally mounted in said main frame for directing air flow thru said frame, c. a control wheel having a partial peripheral ring attached to at least one of said vanes for controlling the direction of at least said one vane, d. a pair of spaced apart flexible side walls on said stationary member forming a control wheel housing, e. a structure having a circular edge formed in each side wall in a manner to provide a bearing, supporting and retaining surface for said peripheral ring, and f. a tapered approach surface in said structure to permit said peripheral ring to be forced up said tapered approach surfaces and between said flexible side walls until it engages said circular edge in bearing relation.
Claim 4
Dependent Claim
141 words
An air flow louver unit, comprising: a. a main frame comprising a stationary member, b. a plurality of vanes pivotally mounted in said main frame for directing air flow thru said frame, c. a control wheel having a partial peripheral ring attached to at least one of said vanes for controlling the direction of at least said one vane, d. a pair of spaced apart flexible side walls on said stationary member forming a control wheel housing, e. a structure having a circular edge formed in each side wall in a manner to provide a bearing, supporting and retaining surface for said peripheral ring, and f. a tapered approach surface in said structure to permit said peripheral ring to be forced up said tapered approach surfaces and between said flexible side walls until it engages said circular edge in bearing relation.
Claim 5
Dependent Claim
107 words
In an air conditioner louver unit having a main frame with stationary member and plurality of vanes pivotally mounted in the main frame, a control means for moving said vanes, comprising: a. a control wheel having a peripheral ring with an outer surface for non-slipping manual engagement and an inner surface for sliding, b. a pair of spaced apart side walls in said stationary member forming a housing for said control wheel, and c. a structure having a circular edge formed in each side wall in a manner to provide a bearing surface for cooperative engagement with and retention of said inner surface and said control wheel.
Claim 6
Dependent Claim
107 words
In an air conditioner louver unit having a main frame with stationary member and plurality of vanes pivotally mounted in the main frame, a control means for moving said vanes, comprising: a. a control wheel having a peripheral ring with an outer surface for non-slipping manual engagement and an inner surface for sliding, b. a pair of spaced apart side walls in said stationary member forming a housing for said control wheel, and c. a structure having a circular edge formed in each side wall in a manner to provide a bearing surface for cooperative engagement with and retention of said inner surface and said control wheel.
Claim 7
Dependent Claim
124 words
In an air conditioner louver unit having a main frame including stationary member and plurality of vanes pivotally attached in the main frame, a control means for operatively engaging and moving said vanes, comprising: a. a control wheel housing in said stationary member having spaced apart side walls defining a cavity having a tapered entrance from one end and a bearing surface adjacent the other end, b. a control wheel engaging said vanes and having a partial peripheral ring with an inner circumference surface thereon, c. each side wall including a half moon structure with a peripheral bearing surface adapted to engage the inner circumference surface of said partial peripheral ring and retain said control wheel within said cavity and provide bearing surface therefor.
Claim 8
Dependent Claim
