Abstract

Apparatus for securing a front cover to an air conditioning unit is disclosed. This apparatus includes a front cover having pivoting means and including a fastening lip for securing the unit in the closed position and a flange for securing the unit in the service position. An air conditioning unit assembly is additionally provided having a pivot means for coacting with the cover and a control panel extension for securing the flange of the cover to maintain the cover in the service position. A support lip is also provided for coacting with the fastening lip of the cover to maintain same in the closed position.

Claims

1. Apparatus for securing a cover to an air conditioning unit such that the cover has a closed position and a service position which comprises:

a cover including a front panel portion and at least one side portion, said front panel portion serving to cover at least a portion of the unit and said front panel portion having both latching means and pivot means associated therewith, and said side portion having an inwardly extending flange; and

an air conditioning unit assembly including a front support adapted to be concealed by the front panel portion of the cover, said front support including a latching element for coacting with the latching means of the cover, pivot projection means extending from the assembly for coacting with the pivot means of the cover, and a control panel extension extending to engage the side portion of the cover to properly position the cover and to engage the flange of the cover to secure the cover in the service position.

2. The apparatus as set forth in claim 1 wherein the air conditioning unit assembly includes a control panel attached to the front support and wherein the control panel extension is formed from a portion of the control panel.

3. The apparatus as set forth in claim 1 wherein the control panel extension has a guide edge for directing the side portion of the cover upon assembly of the cover to the air conditioning unit assembly, a position surface for maintaining the side portion of the cover appropriately spaced relative to the air conditioning unit assembly and a support edge for engaging the cover flange to secure the cover in the service position.

4. The apparatus as set forth in claim 1 wherein the latching means comprises a front support lip attached to the front support and wherein the latching element is a fastening lip extending from the cover, the fastening lip engaging the front support lip to secure the cover in the closed position.

5. The apparatus as set forth in claim 1 wherein the pivot means of the cover includes a pivot opening and wherein the pivot projection means includes a pivot hook, whereby the cover may be assembled to the unit assembly with the pivot hook inserted into the pivot opening such that the cover may both rotate relative thereto and slide vertically in relation thereto.

6. The apparatus as set forth in claim 1 wherein the air conditioning unit assembly further comprises a vertical support positioned to cooperate with the cover flange when the cover is in the fully closed position.
