Abstract

The baffle for preventing the recirculation of discharged air into the intake grille of a packaged terminal air conditioner is provided with means for attaching it to the grille structure without fasteners. A plurality of flexible fingers with snap latches on the ends thereof are inserted between a pair of spaced ribs on the grille, with the fingers being flexed inwardly during the insertion process and then flexing outwardly to engage the snap latches with a front edge of the vertical ribs when the baffle is in place.

Claims

1. An improved grille and baffle structure for an air conditioner of a type having a central portion for receiving outdoor air to be recirculated through a coil and then discharged through side portions of the grille, wherein the improvement comprises:

a grille having vertical ribs for separating the central portion from a side portion of the grille;

a baffle for placement on the rear side of said grille, in alignment with said vertical ribs, the baffle having a sloping surface to inhibit the flow of discharged air into the grille central portion; and

a plurality of flexible fingers attached to and extending from said baffle and engagable with sides of said vertical ribs to secure said baffle to said grille.

2. An improved grille and baffle structure as set forth in claim 1 wherein each of said flexible fingers has a snap latch on the end thereof for engaging a front surface of one of said vertical ribs.

3. An improved grille and baffle structure as set forth in claim 1 wherein said flexible fingers are so disposed as to be insertable between said pair of vertical ribs.

4. An improved grille and baffle structure as set forth in claim 3 wherein each of said flexible fingers has a laterally extending snap latch at the end thereof for engaging a surface of one of said vertical ribs.

5. An improved grille and baffle structure as set forth in claim 4 wherein said snap latch engages a front edge of one of said vertical ribs.

6. An improved grille and baffle structure as set forth in claim 1 and including a plurality of retainer flanges attached to and extending from said baffle and engagable with a side of one of said vertical ribs opposite the side on which said flexible fingers are disposed.

7. An improved grille and baffle structure as set forth in claim 6 wherein each of said plurality of retainer flanges has a bevelled surface thereon to facilitate the easy insertion of the retainer flange into position at said side of said vertical rib.

8. An improved grille and baffle structure as set forth in claim 2 wherein each of said flexible finger snap latches has a bevelled surface thereon for engagement with a rear edge of one of said vertical ribs to facilitate the flexing of said flexible finger to thereby permit the advancement of the snap latch into its final position.

9. An improved grille and baffle structure as set forth in claim 1 and including at least one tab extending rearwardly from the grille and being in such a position as to prevent said baffle from being installed when in an inverted position.

10. An improved baffle structure for a grille of an air conditioning unit of the type having a fan for drawing outside air into a central portion of the grille and discharging air from the side portions thereof, wherein the improvement comprises:

a baffle body for placement on the rear side of the grille and having a vertically extending sidewall and a sloping, deflecting wall;

at least a pair of vertically spaced flexible finger members attached to and extending forwardly from a front edge of said sidewall, said finger members being positionable against a first vertical rib of the grille;

at least a pair of vertically spaced flexible finger members attached to and extending forwardly from a front edge of said deflecting wall, said finger members being positionable against a second vertical rib of the grille; and

a snap latch formed on each of said sidewall and deflecting wall flexible fingers for engaging a front edge of said respective first and second grille vertical ribs.

11. An improved baffle structure as set forth in claim 10, wherein said snap latches each have a beveled surface for engaging a rear edge of one of said vertical ribs to facilitate the flexing of one of said flexible fingers.

12. An improved baffle structure as set forth in claim 10, wherein said side wall and deflecting wall flexible fingers are so disposed as to be insertable between said first and second vertical ribs.

13. An improved baffle structure as set forth in claim 10 and including a plurality of retainer flanges attached to and extending from each of said vertically extending side and deflecting walls and engagable with a side of one of said vertical ribs opposite the side on which said flexible fingers are disposed.

14. An improved baffle structure as set forth in claim 13, wherein each of said plurality of retainer flanges has a beveled surface thereon to facilitate the easy insertion of the retainer flange into position at said side of said vertical ribs.

15. An improved baffle structure as set forth in claim 10, wherein each of said plurality of flexible finger snap latches has a beveled surface thereon for engagement with a rear edge of one of said vertical ribs to facilitate the flexing of said flexible finger to thereby permit the advancement of the snap latch into its final position.
