Installation bracket and system for attaching a ptac chassis into a wall sleeve

Abstract

A bracket includes two vertically elongated portions at right angles to each other, providing a first wall portion and a second wall portion. The first wall portion includes a plurality of “L” or inverted “T” shaped slots. Fasteners are passed through these slots and into the side of the PTAC chassis, capturing the bracket on the slots in a floating arrangement. The second wall portion has at least two engagement tabs that extend forward from the second wall portion. The engagement tabs are sized to fit into corresponding slots at the front side edges of a wall sleeve. Once the tabs are in position through the slots, the bracket is moved downward, pushing the engagement tabs downward, capturing a portion of the wall sleeve between the engagement tab and the second wall portion of the bracket.

What is claimed is: 
     
         1 . A bracket for installing a packaged terminal air conditioner (PTAC) chassis into a wall sleeve, comprising:
 a first wall section configured to mount at a side of the PTAC chassis, the first wall section being elongated and vertically oriented and having at least two L or inverted T shaped slots positioned along the vertical wall section; and   a second vertical wall section which extends from a front edge of the first wall section in a perpendicular direction, the second wall section having at least two tab sections which extend forward and perpendicular to the second wall section, each of the at least two tab sections sized to fit into a respective corresponding slot at a front side edge of the wall sleeve, each of the at least two tab sections having an attached portion that is attached to the second wall, and a free hanging portion that extends downward from the attached portion, wherein the free hanging portion is configured to create an interference with an inside side of the front side edge of the wall sleeve.   
     
     
         2 . The bracket of  claim 1 , wherein the at least two L or inverted T slots are sized to allow a shoulder of a shoulder bolt to move within the slot. 
     
     
         3 . The bracket of  claim 1 , further including a grip tab formed at a top edge of the first wall section which extends outward from the top edge. 
     
     
         4 . The bracket of  claim 1 , wherein there are three tab sections. 
     
     
         5 . The bracket of  claim 4 , wherein a back edge of the free portion is angled such that the back edge is farther away from the second wall at a lowest end of the free portion. 
     
     
         6 . A packaged terminal air conditioning (PTAC) system, comprising:
 a wall sleeve having front side edges at opposite sides of the wall sleeve, at least one engagement slot formed in each front side edge;   a chassis that is sized to fit into the wall sleeve and having opposing sides;   two engagement brackets, with one engagement bracket at each side of the chassis, and fastened to the side of the chassis in a floating arrangement such that the bracket can be moved forward and backward, and up and down relative to the chassis while remaining captured at the side of the chassis; and   each bracket having at least one engagement tab that extends forward and is sized to fit through a corresponding one of the at least one engagement slot at the front side edges of the wall sleeve, and after being passed thought the at least one engagement slot, the engagement bracket is moved to capture the front side edge between the engagement tab and a wall portion of the bracket.   
     
     
         7 . The PTAC system of  claim 6 , wherein each engagement bracket has a first portion having at least two slots having either an “L” shape or an inverted “T” shape through which a respective one of at least two fasteners is passed into the chassis. 
     
     
         8 . The PTAC system of  claim 6 , further including, at a top edge of each of the engagement brackets, a grip tab formed. 
     
     
         9 . The PTAC system of  claim 1 , wherein each engagement bracket of the two engagement brackets includes at least two engagement tabs. 
     
     
         10 . The PTAC system of  claim 6 , wherein, on each bracket of the two engagement brackets, the engagement tabs each have an attached portion connected to a wall portion of the bracket, and a free portion that extends downward separated a distance from the wall portion to which the attached portion is attached. 
     
     
         11 . The PTAC system of claim  11 , where a back edge of the free portion is angled such that the back edge is farther away from the wall portion, to which the attached portion is attached, at a lowest end of the free portion.
