Description:
FIELD OF THE INVENTION 
     This invention relates to telephone enclosures and, more particularly, telephone enclosures having acoustic housings for indoor and outdoor use. 
     DESCRIPTION OF THE PRIOR ART 
     Telephone enclosures having acoustic housings for indoor and outdoor use are known in the art. Such telephone enclosures are shown in U.S. Pat. Nos. 4,706,399; 4,410,930; 4,432,170; Des. 189,129, Des. 260,720, and Des. 300,093, for example. Typically, these enclosures are rather bulky and require two individuals to assemble and repair the enclosures on site. 
     Many of the enclosures have a three-panel construction which includes a perforated inner panel, an acoustic insulation middle panel and an outer panel. The outer panel usually includes some form of signage. At times, one or more of these panels must be replaced, because of vandalism, for example. Presently, replacement of these panels is a time-consuming operation and usually requires two individuals for several reasons. First, the panels can be heavy and awkward to handle. Thus, when replacing one panel, one person must hold in place the panels which are not replaced while the other person replaces the panel. This is to prevent damage to the unreplaced panels from falling out of the enclosure and injuring the repairman. Second, the panels are usually held in place by a rail assembly. When replacing a panel, the rail assembly must be disassembled. After the panel is replaced, usually one individual is required to realign the panels in the rail assembly while the individual reassembles the rail assembly. 
     Therefore, it is an object of the invention to provide a telephone enclosure which can easily be assembled and repaired by one individual. Further, it is an object of the invention to provide an inexpensive telephone enclosure.

Supports 406 mount about the perimeter of the cutout and receive a translucent cover plate 408 therebetween, as shown in FIG. 9. 
     A signage assembly 410 also attaches to the ceiling bottom plate 400. The signage assembly 410 includes an arcuate shaped first ceiling rail 412 having a base 413 with a first section 414 and a second section 415. The first section 414 of the base 413 includes an integral outer first leg 416 and an integral inner second leg 418, both depending from the base 413. A first ceiling panel receiving slot 420 is defined between the first leg 416 and the second leg 418. The first leg 416 is shorter than the second leg 418 and the legs 416, 418 are substantially parallel to each other. A plurality of fastener receiving holes are spaced about the second section 415 of the base 413 which receive weld studs. The weld studs receive appropriate fasteners for attaching the bottom rail 412 to the ceiling bottom plate 400. A V-shaped groove 422 is provided on a surface of the base 413 opposite the legs 416, 418. A seal, such as a caulking material 424, is received by the groove 422 and sandwiched between the base 413 and the first ceiling plate 400. Optionally, caulking material 424 may be replaced by a gasket. A bottom edge of a translucent signage panel 430 is slideably received by the slot 420. 
     The signage assembly 410 also includes an arcuate shaped second ceiling rail 440 which receives a top edge of the signage panel 430. The second ceiling rail 440, which is similar to the bottom rail 412, is positioned across from the first ceiling rail 412. The ceiling rail 440 includes a base 452 having a first section 454 and a second section 456. The first section 454 of the base 452 includes an integral outer first leg 458 and an integral inner second leg 460, both depending from the base 452 toward the first ceiling rail 412. A second ceiling panel receiving slot 462 is defined between the first leg 458 and the second leg 460. The first leg 458 is shorter than the second leg 460 and the legs 458, 460 are substantially parallel to each other. A top edge of the signage panel 430 is slideably received by the ceiling panel receiving slot 462. A plurality of fastener receiving holes are spaced about the second section 456 of the base 452 and receive weld studs. The weld studs receive appropriate hardware for attaching the second ceiling rail 440 to a ceiling top plate 470. The ceiling top plate 470 is of the similar shape as the ceiling bottom plate 400 except it does not have the cutout 404. A V-shaped groove 472 is provided on a surface of the base 452 opposite the legs 458, 460. A seal 474, such as caulking material, is received by the groove 472 and is sandwiched between the base 452 and the ceiling top plate 470 forming a compartment between the bottom plate 400 and the top plate 470. 
     The first ceiling rail 412 attaches to the second ceiling rail 440 by a diffuser separator 480, see FIGS. 5 and 21. The diffuser separator is C-shaped having two end segments 482 depending from a middle segment 484 that abuts an end of panel 430. Each end segment 482 has a fastener receiving hole 486 through which a weld stud passes. The weld studs receive fasteners passing through the first ceiling rail 412 and second ceiling rail, respectively. The middle segment 484 includes an integral stepped plate 488. The stepped plate 488 includes a first rectangular segment 490 received between first ceiling rail leg 416 and second ceiling rail leg 458 and a second rectangular segment 492 received between first ceiling rail leg 418 and second ceiling rail leg 460. The panel 430 abuts against first rectangular segment 490, which prevents movement of the pane 430. The length and the width of the first segment 490 are greater than the length and width of the second segment 492. One or more diffuser separators 480 may be used in the present invention. This enables the use of several signage panels 430 in the signage assembly 410. In the present case, three signage panels 430 are used. 
     As shown in FIGS. 21 and 22, a lighting bracket 500 mounts to an inner surface of the top plate 470. The bracket receives a lighting fixture that includes two fluorescent bulbs 510, as shown in FIG. 9. Sufficient hardware and electric lines are provided to energize the bulbs 510. Although this hardware is not shown it is well known in the art. When the bulbs 510 are energized, the phone booth enclosure as well as the signage panel 430 are illuminated. 
     Most of the elements of the telephone enclosure, with the exception of electrical components, may be made of thin gauge stainless steel or aluminum, or plastic. This affords a lightweight enclosure, on the order of 80 pounds. Thus, the enclosure can be assembled and repaired by one individual. Further, the panel assemblies 20, 22 can easily be replaced if damaged, and repair can easily be made at a repair shop. The lightweight panel assemblies also aid in allowing one person to replace them. Likewise, the signage panel 430 may be easily replaced by removing the ceiling top plate 470, the second ceiling rail 440 and the diffuser separator 480; replacing the panel within the slot 420 of the first ceiling panel 412; and then replacing the removed elements. Furthermore, as can be seen, the parts of the enclosure 10 can be easily and cheaply manufactured. This results in an inexpensive telephone enclosure 10. 
     Having described the presently preferred embodiment of the invention, it is to be understood that it may be otherwise embodied within the scope of the appended claims.
