In the following detailed description, and the drawing, like reference characters indicate like parts.

In FIGS. 1 and 2, inclusive, is shown a wall cabinet 20 which includes an outer shell or casing 22 and a framework 23 (FIG. 3) on which circuit boards 24 and other electrical components can be mounted. Details of the circuit boards and electrical components have been omitted for clarity. As shown in FIG. 12, the outer shell 22 includes a front or face panel 26 provided with an outwardly extending flange 28 defining a speaker cavity and a. continuous flange 29, which extends into engagement with a face 30 of a wall 31. Cylindrical rod-like bosses 32 (only two of them are shown) on the interior of the face panel 26 extend to the framework 32 and receive screw fasteners 32' which attach the framework 23 to the outer shell 22. The outer shell 22 can be molded of appropriate plastic material with the bosses 32 being formed integrally therewith.

Details of construction of the framework 23 are shown in FIGS. 7 to 9, inclusive. The framework 23 includes lengthwise angle

shaped frames

33 and 34 and uprightgenerally angle-

shaped frames

36 and 37.

Tab flanges

41 and 42 at opposite ends of the frame 36 are welded to the

lengthwise frames

33 and 34, respectively.

Tab flanges

43 and 44 at opposite ends of the frame 37 are welded to the

lengthwise frames

33 and 34, respectively. As shown in FIG. 7, the

frames

33, 34, 36, 37 form a generally rectangular framework. A cross frame 45 spans the lengthwise frames intermediate ends thereof,

tab flanges

46 and 47 at opposite ends of the cross frame 45 being welded to the lengthwise frames. Openings 48 are provided in the

lengthwise frames

33 and 34 to receive the fasteners 32 (FIG. 12) by means of which the outer shell 22 is attached to the framework 23.

The cabinet is hung by means of an upper mounting formation or bracket 51 which includes flanges 52 and 53 (FIG. 12) which engage face to face with flanges of the upper lengthwise frame 33. The bracket 51 is attached to the upper lengthwise frame 33 by welding. In addition, the bracket 51 includes a horizontal flange 54 and a sloping flange 56 which slopes at an angle approximately degrees to the horizontal flange 54. As shown in FIG. 8, the sloping flange 56 is provided with a slot 58 intermediate ends thereof.

-The lower lengthwise frame 34 carries a lower clamping assembly 59. The assembly 59 includes a generally Z-shaped lower latch 61 which, as shown in FIG. 14, includes a body 62 and

flanges

63 and 64 at opposite ends of the body which extend normally to the body. An opening 66 is provided in the body 62. The body of the lower latch 61 extends through a slot 67 (FIG. 10) in the angle brace 68 attached to the lower lengthwise frame 34 with the flange 63 of the lower latch 61 adjacent and engageable with the brace 68. The body 62 additionally extends through a slot 69 (FIG. 15) in the vertical flange 70 of the lower lengthwise frame 34. An adjustment bolt 72 extends upwardly through an opening 66 in the body of lower latch 61 and through an opening or slot 73 (FIG.

13) in the horizontal flange 74 of the lower lengthwise frame 34. A nut 76 (FIGS. and 12) receives the adjustment bolt 72. The nut 76 is supported in a nut anchor 76' anchored in the slot 73 (FIG. 13). Turning of the bolt 72 causes the flange 64 of the lower latch 61 to move up or down as indicated in FIG. 12. A head 76" on the bolt 72 engages the body 62 of the lower latch while the left hand end of the latch is anchored in the slot 67.

The cabinet is hung on a mounting plate 77. Details of the construction of the mounting plate 77 are shown in FIGS. 4 and 6, inclusive. The mounting plate 7 7 includes a body 78, an upper flange or lip 79 and a lower flange or lip 81, the

flanges

79 and 81 intersecting the body 78 at obtuse angles of approximately 150 degrees. Openings 82 in the body 78 of the mounting plate 77 are provided to receive fasteners 83 (FIG. 12) for attaching the mounting plate 77 to the wall 31 with the body 78 thereof in flatwise engagement with the face of the wall.

Other openings

84 and 86 are provided in the body 78 for receiving connection cables (not shown) which connect components in the cabinet with other components.

The upper flange 79 of the mounting plate 78 slopes at an angle to engage flatwise with the flange 56 of the bracket 51 as shown in FIG. 12. A tab portion 88 of the upper flange 79 is bent upwardly, as shown in FIGS. 4 and 6. The tab portion 88 is received in the slot 58 (FIG. 8) of the bracket 51 to ensure proper centering of the framework 23 on the mounting plate 7 7.

When the cabinet is hung as shown in FIG. 12 with the sloping flange 56 of the bracket 51 overlying the upper flange 79 of the mounting plate 77 and with the tab portion 88 received in the slot 58, as shown in FIG. 11, the adjustment bolt 72 can be turned to cause the lower latch 61 to swing counterclockwise as shown in FIG. 12 causing the flange 64 of the lower latch 61 to engage the lower flange 81 of the mounting plate and draw the cabinet inwardly toward the wall 31 causing the edge of the flange 29 to engage the wall face 30 firmly. An access opening 91 '(FIG. 2) in the shell 22 permits insertion of a screwdriver or the like (not shown) for turning the adjustment bolt 72.
