, AIR CONDITIONING WINDOW MOUNTING DEVICE Filed Aug. 3, 1955 2 Sheets-Sheet 2 INVENTORL Emanuef ,BILZ rev' 1' I M W "l g S U d States Patent-(f) AIR CONDITIONING WINDOW MOUNTING DEVICE This invention relates to air conditioning apparatus of the type generally referred to as self-contained or window units. More particularly, this invention relates to the combination with an air conditioning unit of structure which insures dependable support and also insures the supplying of fresh airto the unit and the disposalof warm air therefrom.

An object of this invention is to provide improved apparatus of the above'character, which is light in weight, simple in construction, and eflicient and dependable in use. A further object is to provide theabove in such a manner to avoid the difficulties which have been encountered with similar apparatus in the past. A further object is to provide a combined air conditioning unit and supporting structure therefor, which is adaptable to meet the various problems which are encountered in actual use. These and other objects will be in part obvious and in part pointed out below.

In the drawings:

Figure 1 is a perspective view of one embodiment of the invention;

Figure 2 is a top plan view of the apparatus of Figure 1 on the sectional line 2-2 of Figure 1;

Figures 3 and 4 are enlarged sectional views respectively on the lines 3-3 and 4-4 of Figure 2.

Figure 5 is an exploded view of components of the embodiment of Figures 1 and 2;

Figure 6 is a view similar to Figure 5, but illustrating another embodiment of the invention; and

Figures 7 and 8 are perspective views, showing other embodiments of the invention.

In the illustrative embodiment of the invention of Figure l, a self-contained air conditioning unit 2 is mounted at the level of the sill 4 of a window frame 6 having a sliding window 8 therein. Unit 2 projects into the room from sill 4, and is supported at the sill and also at the projecting corners by a pair of metal legs 10. Mounted upon unit 2 are three casing elements or components shown best in Figure 5, and comprising a top plate 12 and a pair of

side cowls

14 and 16. Referring again to Figures 1 and 2, cowl 16 is at the left, and cowl 14 is at the right, and the cowls are similarly constructed, but have their elements reversely positioned relative to each other. Cowl 14 (Figure 5) has a side wall 18, and a bottom wall 20, and an upstanding inverted-U flange 22 parallel to wall 18. Wall 18 connects with an angularly positioned wall 24 which terminates in a flange 26 in alignment with the inverted-U flange 22.

Walls

18, 20 and 24 are lined with a layer of sound insulated material 28, as shown best in Figure 2. The top plate 12 overlies the condenser section 30 of unit 2, and the air filter, and cooling section 32 projects beyond this cover plate. Section 30 has a bottom wall 34 (see Figure 4) with an upstanding side flange 36. The inverted-U flange 22 of cowl 14 is snugly fitted onto this upstanding side flange 36 so as to provide a secure attachment between the cowl and the bottom wall of unit 2. As shown best in Figure 2,

2 ,810,335 Patented O t. 22,1957

" flange 22 has a slot 40 in which the vertical member is positioned. This accurately positions the cowl members longitudinally of'the inverted-U flange, and prevents sliding thereof. Cowl 16 is similarly assembled to the lefthand side of unit 2, and top plate 12 has downwardly extending

flanges

42 and 44 which fit snugly along the outer surfaces of the cowls. The top plate 12 and the cowls are secured together and to'unit 2 by screws not shown. v

'Unit 2 and the top plate and cowls are positioned within the room so that the window 8 may be opened or entirely closed However, when the unit 2 is operating, window 8 is positioned as shown in the drawings, with the bottom rail of the window at the level of the cover plate 12. As shown best in Figure 3, the edge of plate 12,

which extends along the window carries a flexible bead 46 its top edge a sealing head 54 which engages the window rail'and provides a seal when the window is positioned as shown. However, door 48 may be opened regardless of the position of the window. Hence, when the window is open, the space to the right and above the air conditioning apparatus is entirely free. Under some circumstances, door 48 is opened to permit the entry of fresh air even though unit 2 is operating.

Referring again to Figure 2, the condensing section of unit 2 has air inlet openings at its sides throughout the zones covered by

cowls

14 and 16, and the unit exhausts air along the side parallel to window 8. Hence, when window 8 is positioned as shown, air is drawn in through the

cowls

14 and 16, and is exhausted in the space between them. Some fresh air may be directed into the room and added to the recirculated air. The recirculated air is drawn into the unit at 56, and is mixed with the fresh air and cooled, and then discharged into the room at 58.

It has been indicated above, that the unit is supported by the window sill 4 and the legs 10. Legs 10 are threaded into the bottom of the unit frame, and they provide very satisfactory support.

In the embodiment of Figure 6, cover plate 12 is omitted and

cowls

14 and 16 are replaced by cowls and 62.

Cowls

60 and 62 are similar to

cowls

14 and 16, except that each of them includes a top wall 64 and a downwardly extending flange 66. These cowls are assembled into unit 2 in the same manner as

cowls

14 and 16 are assembled with the additional step of projecting flanges 66 down between the side walls of the unit 2 and the unit frame. The operation is the same as described above in connection with the embodiment of Figures 1 to 5.

In the embodiment of Figure 7, the cowls are formed as integral parts of a shell, including a top wall 68 and a bottom wall 70. This shell is rigidly attached to the unit by screws not shown. I

The embodiment of Figure 8 is adapted for use with windows having an opening of only the width of the unit 2. In this embodiment, the

cowls

72 and 74 are formed as upwardly projecting conduits forming the ends of rectangular, horizontal chamber 76. Chamber 76 has a louvered inlet at 78, through which the air is drawn into the chamber, and the air passes from the ends of the chamber upwardly through the

cowls

72 and 74, and thence into the unit 2, as in the embodiment of Figures 1 to 5. Under some circumstances, the apparatus of Figure 8 has chamber 76 at the top so that the air passes from this chamber a b ies downw r lxthmus h cowls.
