Abstract

A display system provides a portable telephone with a plurality of distinctive appearances. An overlying cover is removably attachable to a telephone housing which includes operating buttons and an indicia panel. The cover has a primary opening for viewing the indicia panel and secondary openings for free reception therethrough of the operating buttons. A transparent window member includes a first peripheral edge encompassing the outer face and a first recessed peripheral ledge projecting outwardly to a terminal peripheral edge. A collar removably attachable to the cover has an aperture similar in size and shape to the primary opening of the cover and an inner surface with an inner peripheral recess adjacent the aperture for capturing reception of the peripheral ledge of the transparent window member between the collar and the cover so that the transparent window member overlies the indicia panel on the housing. A second outer peripheral edge on the collar defines the extent of the outer face and a second outwardly projecting peripheral ledge is recessed with respect to the outer face thereof. In turn, a fixing collar is removably attachable to the cover and has an aperture sized and shaped for contiguously encompassing the second outer peripheral edge of the collar when attached to the cover and has an inner peripheral recess adjacent the aperture for capturing reception of the second peripheral ledge of the collar between the collar and the cover. The cover, window member, collar and fixing collar may all have distinctive colors.

Claims

1. A display system for providing a portable telephone with a plurality of distinctive appearances comprising:

a housing containing components including a plurality of operating buttons for the operation of the telephone and an indicia panel for displaying information concerning operation of the telephone;

a cover coextensive with and overlying said housing and being removably attachable to said housing to enclose said components within said housing, said cover including an outer face having a primary opening for viewing said indicia panel on said housing and a plurality of secondary openings for free reception therethrough of said operating buttons of said housing, said cover having a first distinctive color;

a transparent window member including an outer face having a first peripheral edge encompassing said outer face and a first peripheral ledge recessed with respect to said outer face thereof and projecting outwardly therefrom to a terminal peripheral edge;

a first collar removably attachable to said cover including an outer face having an aperture similar in size and shape to the primary opening of said cover and including an inner surface having an inner peripheral recess adjacent the aperture for capturing reception of said peripheral ledge of said transparent window member between said first collar and said cover when attached to said cover so that said transparent window member overlies coextensively said indicia panel on said housing, said first collar including a second outer peripheral edge defining the extent of said outer face and a second peripheral ledge recessed with respect to said outer face thereof and projecting outwardly therefrom, said collar having a second distinctive color;

a fixing collar removably attachable to said cover, said fixing collar including an outer face having an second aperture sized and shaped for contiguously encompassing said second outer peripheral edge of said first collar when attached to said cover, and having an inner peripheral recess adjacent the second aperture for capturing reception of said second peripheral ledge of said first collar between said fixing collar and said cover, said fixing collar having a third distinctive color.

2. A display system as set forth in claim 1

wherein said outer faces of said window member, of said first collar, and of said fixing collar are all coplanar when assembled on said cover.

3. A display system as set forth in claim 1

wherein said window member has a fourth distinctive color.

4. A display system as set forth in claim 1

wherein said cover has a plurality of mounting holes adjacent said primary opening;

and

wherein said first collar includes a plurality of mounting pegs projecting transversely from said inner surface and fittingly received in said mounting holes when said first collar is attached to said cover.

5. A display system as set forth in claim 4

wherein the mounting holes in said cover are generally circular;

and

wherein each of said mounting pegs is generally shaped as a right truncated cone having a longitudinal axis perpendicular to said inner surface and including a base end at said inner surface, a tip end distant from said base end, an outer peripheral surface, and a longitudinally extending rib having a depth projecting radially away from said outer peripheral surface which is a maximum at said base end and a minimum at said tip end.

6. A display system as set forth in claim 1 including:

key means for properly positioning said first collar on said cover and said window member on said first collar.

7. A display system as set forth in claim 6

wherein said key means includes said plurality of transversely projecting mounting pegs and their associated mounting holes in said cover being so located that said first collar can be positioned on said cover in only one mutual orientation and that said window member can be positioned on said first collar in only one mutual orientation.

8. A display system as set forth in claim 7

wherein the aperture is generally rectangular and defined by first and second opposed laterally extending generally parallel window edges and third and fourth opposed longitudinally extending generally parallel window edges;

and

wherein a pair of said mounting pegs projects at least partly from said inner peripheral recess at spaced locations adjacent said first window edge; and

wherein a single one of said mounting pegs projects at least partly from said inner peripheral recess adjacent said second window edge; and

wherein said terminal peripheral edge is contoured to freely receive said base ends of said mounting pegs.

9. A display system as set forth in claim 1 including:

means for removably mounting said cover on said housing.

10. A display system as set forth in claim 1

wherein said fixing collar includes:

a peripheral flange extending transversely of said outer face engageable with said cover for attachment thereto;

a plurality of spaced inwardly projecting locking tabs; and

a frictional male tab projecting transversely from said inner face;

wherein said cover includes;

a rim generally congruent with said peripheral flange and upstanding from said outer cover face and having a plurality of outwardly facing locking recesses;

an inner surface; and

a plurality of locking female tabs integral with and extending transversely of said inner surface adjacent a mounting slot distant from said locking recesses;

whereby when fixing said collar is attached to said cover, said peripheral flange is located proximate said rim, said peripheral flange being sufficiently flexible to enable said locking tabs to lockingly engage with said associated ones of the locking recesses; and

whereby said male tab projects through the mounting slot in said cover and is lockingly engaged with said plurality of locking female tabs.
