Phillips, Whitestone, New York, N.Y., assignor to Triangle Sheet Metal Works, Inc, New Hyde Park, N.Y., a corporation of New York Filed Oct. 17, 1961, Ser. No. 145,650 21 Claims. (Cl. 237-79) The present invention relates generally to improvements in air conditioning unit enclosure structures and relates more particularly to a prefabricated enclosure structure which may be readily assembled to the corner of a room delineated by the floor and a wall thereof for housing air conditioning heat exchange units and the like.

It is a conventional practice in the heating and cooling of buildings to provide heat exchange units, usually connected by pipes, along the exposed wall of the room to be air conditioned, and to circulate a heat exchange medium through the units at the temperature required to heat or cool the conditioned space. The heat exchange units are generally housed in enclosures having openings formed in the walls thereof to permit the circulation of air therethrough. The enclosures heretofore employed for housing these heat exchange units possess numerous drawbacks and disadvantages. They are expensive devices which are difficult to ship and assemble, and are usually custom fabricated for each particular job. Their erection is highly timeconsuming and requires skilled labor. In addition, the resulting enclosure is usually structurally weak and unattractive in appearance and otherwise leaves much to be desired.

It is therefore a principal object of the present invention to provide an improved enclosure structure.

Another object of the present invention is to provide an improved prefabricated enclosure structure for housing air cooling and heating units extending along a wall of a room.

Still another object of the present invention is to provide an improved prefabricated enclosure structure which is easily and rapidly assembled and erected along a wall of a room with a minimum employment of skilled labor.

A further object of the present invention is to provide a corner enclosure for room heating and cooling systems which is highly adaptable and versatile and permits ready access to the interior thereof.

Still a further object of the present invention is to provide an improved enclosure structure of the above nature characterized by its simplicity, ruggedness, attractive appearance and low cost.

The above and other objects of the present invention will become apparent from a reading of the following description taken in conjunction with the accompanying drawings wherein:

The enclosure 10 is a strong and rigid structure which is easily and rapidly erected and assembled. Access to the enclosed area is readily available merely by lifting the intermediate panel 59 and, if desired, then detaching the

panels

58 and 60 and also by removing the front panels 26a. Full disassembly of the enclosure 10 is likewise simply effected. The number and lengths of the various components may be as desired and depend on the overall length of the finished enclosure. The shipping and storing of the members forming the enclosure is greatly facilitated by reason of their substantially flat configurations.

The embodiment of the present invention, illustrated in FIGURE 6 of the drawing, differs from that previously described principally in the construction of the wall bracket and the reinforcing rib coupling arrangement. Specifically, the wall bracket, designated by the reference numeral 71, includes an elongated horizontal angle member or a plurality of longitudinally spaced angle memers each provided with a vertical leg 72 abutting and fastened to the wall 11 and an upper forwardly projecting leg 73. Mounted on the wall bracket is a coupling member 74 formed of sheet metal and including a vertical web 76 secured to the bracket leg 72 by screws or other suitable fasteners and having formed at its bottom a rearwardly directed arm terminating in a depending leg 77 abutting the wall 11 and carrying a forwardly projecting shelf 78. A loop section 79 extends forwardly from the upper edge of the web 76 and embraces the angle member leg 73 and has integrally formed along the rear edge thereof a forwardly directed flange 80a which overlies the loop section 79. Mounted on the top of the mullion 26 is a bracket 80, which, like the bracket 38, includes an upper web 81 provided along its front edge with a depending leg 82, and along its rear edge with 21 depending leg 83 which is suitably fastened to the mullion 26. The reinforcing ribs 84 differ from the ribs 44 in that an angle member is disposed at the front end of the rib 84 and includes a horizontal leg 86 welded to the horizontal web of the rib 84 and a depending vertical leg 87.

The erection and assembly of the enclosure last described differs from that first described only in that the rear ends of the ribs 84 are brought to rest on the shelves 78 and the front ends are fastened to the brackets 80 by nuts 88 and bolts 88a registering with aligned openings in the leg 87 and bracket leg 83.

Another form of wall bracket for use in the present enclosure structure is illustrated in FIGURE 7 of the drawing and includes an angle member having a vertical leg 90 suitably secured to the wall 11 and an upper forwardly directed leg 91. The reinforcing cross rib 92 is similar in configuration to the previously described cross rib 44. A U-shaped spacer member 94 includes a vertical arm 96 abutting the bracket leg 90 an upper forwardly directed leg 97 underlying the bracket leg 91 and a lower forwardly directed leg 98. The spacer member leg 98 rests upon the rear end of the horizontal web of the rib 92. The bracket 90, spacer member 94 and rib 92 may be releasably locked in assembled condition by a bolt 99 having a countersunk head nesting in a corresponding aperture in the bracket leg 91 and a shank registering with aligned openings in the spacer member legs 97 and 98 and the web of the rib 92, and having a threaded end engaged by a nut 100. The rear border of the panel web 66 is fastened to the bracket leg 91 by suitable screws 101. In all other respects, the construction and assembly of the last enclosure are similar to those previously described.

A support member 105 of substantially U-shaped configuration is fastened to the wall 11 by screws 106 passing through the vertical arm 107 of the support member 105 and the underlying vertical bracket leg 103.

Horizontal legs

108 and 109 project forwardly from the upper and lower edges respectively of the arm 107, the upper leg 108 being parallel to and spaced slightly below the angle member leg 104 and the lower leg 109 being provided with an upwardly directed tongue 110.

The reinforcing cross ribs 111 are channel shaped and each includes an upper horizontal web 112 provided with depending side legs 113 which terminate in outwardly directed horizontal flanges 114. The rear end of the rib 111 rests on the support leg 109 and is secured thereto by nuts 116 and bolts 116a registering with aligned openings in the flanges 114 and leg 109 and the forward end of the rib 111 is similarly coupled to the corresponding bracket 38 as earlier described. Formed in the rib upper horizontal web 112 between the ends thereof are longitudinally spaced pairs of longitudinally and laterally spaced upwardly directed lugs 117 which delineate a pair of longitudinally spaced locking grooves releasably engaging the lower borders of the panel flanges 64 and 67 and supplanting the locking assembly 51. The erection and operation of the structure last described are similar to those earlier described and are obvious from the above description.

Referring now to FIGURE 11 of the drawings which illustrates another form of the present invention, the reference numeral 120 designates a longitudinally extending floor mounted bracket corresponding to the bracket 20 and including a vertical web 121, and a rearwardly directed upper platform 122 terminating in an upwardly directed lip 123. The mullions 126 are mounted atop the bracket 120 in the manner earlier described and each has an angle member 127 aflixed to its upper border and provided with a rearwardly directed horizontal leg 128. A leveling bolt 129 engages a tapped bore formed in the angle member leg 128 and is provided with a flat head 130 and is engaged by a lock nut 132 abutting the top face of the angle member leg 128.

A longitudinally extending bracket 138 is mounted atop the mullions 126 and includes a horizontal top Web 139 resting on the bolt heads 130 which have been previously adjusted and locked at their proper level. Depending from the front edge of the web 139 is a front skirt 140 terminating in a rearwardly directed lip engaging a pad located on the mullion 126. A rear skirt 141 depends from the rear edge of web 139 and has formed along its lower edge a'rearwardly projecting platform 142 terminating in an upwardly directed lip 143.

The cross ribs 144 are channel shaped, each including a horizontal top web 146 and depending side legs 147. Formed adjacent to the leading edges of the side legs 147 are vertical slots 148 which releasably engage the lips 143, the front ends of the rib legs 147 resting on the platform 142. The rear ends of the ribs 144 may be secured to the wall bracket in the manners earlier described. A pair of longitudinally spaced upwardly directed front and rear lips 149 are formed in the rib top web 146 intermediate the ends thereof.

The front and rear top panels 150 and 151 are somewhat similar in construction to those earlier described, being provided with rectangular top webs 152 and 153 respectively. Depending from the rear edge of the web 152 is a rearwardly stepped flange 154 provided with a horizontal platform 156 and terminating in a frontwardly directed leg 157 engaging a corresponding lip 149. Depending from the front edge of the web 153 is a frontwardly stepped flange 158 provided with a horizontal platform 159 and terminating in a rearwardly directed leg 160 engaging a corresponding lip 149. In other respects the panels 150 and 151 are like those earlier described.

A support plate or strip 164 is located between the panels 150 and 151 and is provided with front and rear depending flanges 165 which rest on the

platforms

156 and 159 and are spaced from the confronting faces of the

flanges

154 and 158. Suitably secured to and depending from the plate 164 is a bolt 166 which registers with an aligned opening in the rib web 146 and is locked in position by a wing nut 167. The intermediate top panel 161 includes a horizontal rectangular web 163 resting on the plate 164 and provided with front and rear depending flanges 168. The flanges 168 register with the grooves delineated by the confronting faces of the

flanges

165 and 154 and 158 and rest on the

platforms

156 and 159, the web 163 being coplanar with the webs 152 and 153. The front panels 169, like the panels 26a, extend between the mullions 126. The panels 169 each include a louvered front vertical wall 170 provided along its lower edge with a rearwardly directed flange 171 resting on the rearwardly directed bracket platform 122. A latch member 172 includes a horizontal leg 173 overlying and secured to the flange 171 and provided along its rear edge with a vertical leg 174 terminating in a rearwardly projecting downwardly facing hook section 175 which engages the upper border of the bracket upwardly directed lip 123. The upper border of the panel 169 projects into the bracket 138. In applying the panel 169 to the assembly the upper border thereof is inserted into the bracket 138 and it is then brought to a substantially vertical position and dropped to the locked posi- '3' tion illustrated in the drawing. Otherwise, the assembly and employment of the enclosure last described is similar to those earlier described.
