Abstract
Abstract A hand-held radio has thumbwheels for channel selection extending outwardly of an aperture in the top panel of the case, and a cover of resiliently deflectable transparent synthetic resin is disposed thereover and effects a seal thereabout to substantially prevent rain and spray from entering the interior through the apertures about the thumbwheels. The cover has a pedestal portion with a top wall spaced above the thumbwheels and with an inclined sidewall which is spaced laterally outwardly from the thumbwheels, and a peripheral flange extends about the base of the sidewall. A clamping plate has an aperture through which the pedestal portion extends, and it overlies the flange of the cover. Fasteners seated in the clamping plate tightly clamp the flange of the cover against the top panel of the case to effect a seal. The user is able to deflect the cover top wall downwardly and then laterally to rotate the thumbwheels.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
A handheld radio comprising (a) a frame supporting electronic components; (b) a case surrounding said frame including a top panel with at least one opening therethrough; (c) a multiplicity of thumbwheels rotatably supported in said case and having a circumferential portion thereof extending through said opening in said top panel; (d) a resiliently deflectable cover disposed on said top panel and having a pedestal portion overlying said thumbwheels including a top wall spaced thereabove and a depending sidewall extending thereabout to said top panel, said cover including a flange extending outwardly about the periphery of said sidewall and along a portion of the surface of said top panel, said cover being fabricated from a relatively transparent synthetic resin and being readily deflectable by a finger of the user of the radio to depress the top wall into frictional engagement with a thumbwheel and thence movable laterally to effect rotation thereof; (e) a clamping plate overlying said flange of said cover and having an aperture therein through which said pedestal portion extends; and (f) fasteners extending through said clamping plate and cover and into said top panel to provide sealing engagement between said flange and said top panel to prevent rain and spray from entering said case about said thumbwheels.
Claim 2
Dependent Claim
209 words
A handheld radio comprising (a) a frame supporting electronic components; (b) a case surrounding said frame including a top panel with at least one opening therethrough; (c) a multiplicity of thumbwheels rotatably supported in said case and having a circumferential portion thereof extending through said opening in said top panel; (d) a resiliently deflectable cover disposed on said top panel and having a pedestal portion overlying said thumbwheels including a top wall spaced thereabove and a depending sidewall extending thereabout to said top panel, said cover including a flange extending outwardly about the periphery of said sidewall and along a portion of the surface of said top panel, said cover being fabricated from a relatively transparent synthetic resin and being readily deflectable by a finger of the user of the radio to depress the top wall into frictional engagement with a thumbwheel and thence movable laterally to effect rotation thereof; (e) a clamping plate overlying said flange of said cover and having an aperture therein through which said pedestal portion extends; and (f) fasteners extending through said clamping plate and cover and into said top panel to provide sealing engagement between said flange and said top panel to prevent rain and spray from entering said case about said thumbwheels.
Claim 3
Dependent Claim
