Auto-set oscillating louver design

Claim 2

An improved air flow directing apparatus for an air conditioning system of the type having an air discharge opening with pivotable vanes mounted therein for directing the flow of discharge air into an adjacent space comprising: vane pivoting means for pivoting the vanes in reciprocating fashion through a defined angle; means including a preselector element for preselecfing a fixed angular orientation for the vanes by adjusting, independently of the position of the vanes at the time, the position of said preselector element to a position representative of said preselected orientation; and stop means responsive to said preselecting means for automatically stopping the pivoting of the vanes when they subsequently arrive at said preselected fixed singular orientation.

Claim 3

An air flow directing apparatus as set forth in claim 1 wherein said vane pivoting means comprises a drive mechanism which is mechanically connected to said vanes.

Claim 4

An air flow directing apparatus as set forth in claim 2 wherein said stop means operates to stop said drive mechanism.

Claim 5

An air flow directing apparatus as set forth in claim 2 wherein said drive mechanism comprises a propeller mounted in the air discharge opening, said propeller having its axis generally in alignment with the flow of discharge air.

Claim 6

An aif flow directing apparatus as set forth in claim 4 wherein said stop means includes a damper which is moved against said propeller to cause it to stop turning.

Claim 7

In an air conditioning apparatus of the type having an air discharge opening with vanes that automatically rotate from side to side with the purpose of sweeping the air flow pattern between two extreme angled positions, an improved mechanism for setting the vanes at a desired fixed orientation comprising: a drive mechanism for providing continuous pivoting motion to the vanes; means including a preselector element, for preselecting a desired position of fixed orientation for the vanes by adjusting, independently of the position of the vanes at the time, the position of said preselector element to a position representative of said preselected orientation; and stop means responsive to said preselection means for causing said drive mechanism to stop when the vanes are subsequently pivoted by said drive mechanism to said desired position.

Claim 8

In an air conditioning apparatus of the type having an air discharge opening with vanes that automatically rotate from side to side with the purpose of sweeping the air flow pattern between two extreme angled positions, an improved mechanism for setting the vanes at a desired fixed orientation comprising: a drive mechanism for providing continuous pivoting motion to the vanes; means including a preselector element, for preselecting a desired position of fixed orientation for the vanes by adjusting, independently of the position of the vanes at the time, the position of said preselector element to a position representative of said preselected orientation; and stop means responsive to said preselection means for causing said drive mechanism to stop when the vanes are subsequently pivoted by said drive mechanism to said desired position.

Claim 9

The mechanism as set forth in claim 6 wherein said dtive mechanism includes a propeller which is mounted in the air discharge opening, said propeller having its axis in general alignment with the air flow pattern.

Claim 10

The mechanism as set forth in claim 7 wherein said stop means includes a damper which is automatically moved against said propeller to cause it to stop turning.

Claim 11

The mechanism as set forth in claim 6 wherein said selecting means can be so positioned as to not cause said stop means to be operable.
