Abstract
Abstract Housing assembly for miniature radio apparatus, such as a radio pager, having a molded frame member which houses the chassis and forms one end and two opposite outer sides of the housing. Space for a battery is provided adjacent the end of the housing formed by the frame member. A flexible plastic insulating member has a central part secured to the end of the frame member with flaps covering the chassis and the battery. A U-shaped cover member slides in grooves in the frame member to form the other end and the other two outer sides of the housing, thereby providing a completely enclosed housing. The cover bears against the flaps to hold the chassis and battery in the proper positions within the housing. The cover can slide with respect to the frame member to open the housing at one end to afford access to the battery. A spring biased detent is secured to the frame member, which cooperates with an opening in the cover member to hold the cover completely closed. This detent can be overriden to permit the cover to slide part way open for access to the battery. The detent engages a tongue at a further opening in the cover to prevent further movement of the cover with respect to the housing, preventing access to the radio chassis. A key may be provided to release the detent from the tongue for removal of the cover from the frame member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
176 words
Miniature battery operated radio apparatus including in combination, a frame member having portions forming one end and two opposite sides of a housing, a radio chassis positioned within said frame member, said frame member having a portion with an opening adapted to receive a battery adjacent said one end of the housing, a U-shaped cover member forming the opposite end and two opposite sides of the housing, said frame member being adapted to receive said cover member in sliding relation thereon, with said cover member having a first position with respect to said frame member to form a completely enclosed housing, detent means cooperating with said cover member to hold said cover member in said first position, said cover member being slidable to a second position with respect to said frame member to open said housing adjacent said one end thereof to provide access to a battery therein, said cover member having a portion cooperating with said detent means to hold said cover member in said second position and prevent complete removal of said cover member.
Claim 2
Dependent Claim
176 words
Miniature battery operated radio apparatus including in combination, a frame member having portions forming one end and two opposite sides of a housing, a radio chassis positioned within said frame member, said frame member having a portion with an opening adapted to receive a battery adjacent said one end of the housing, a U-shaped cover member forming the opposite end and two opposite sides of the housing, said frame member being adapted to receive said cover member in sliding relation thereon, with said cover member having a first position with respect to said frame member to form a completely enclosed housing, detent means cooperating with said cover member to hold said cover member in said first position, said cover member being slidable to a second position with respect to said frame member to open said housing adjacent said one end thereof to provide access to a battery therein, said cover member having a portion cooperating with said detent means to hold said cover member in said second position and prevent complete removal of said cover member.
Claim 3
Dependent Claim
47 words
Radio apparatus in accordance with claim 1 wherein said detent means includes a spring biased member secured to said frame member and having a projecting portion, and said cover member has an opening to receive said projecting portion when said cover member is in said first position.
Claim 4
Dependent Claim
43 words
Radio apparatus in accordance with claim 2 wherein said spring biased member is a plastic member flexibly secured to said frame member, and including a leaf spring engaging said plastic member to hold said projecting portion in position to engage said cover member.
Claim 5
Dependent Claim
72 words
Radio apparatus in accordance with claim 2 wherein said cover member has a cut out portion forming a tongue which engages said projecting portion of said detent means when said cover member is in said second position, whereby said spring biased member must be moved so that said projecting portion clears said tongue to permit movement of said cover member from said second position to permit removal thereof from said frame member.
Claim 6
Dependent Claim
23 words
Radio apparatus in accordance with claim 4 wherein said projecting portion has a recess shaped to receive said tongue to provide interengagement therebetween.
Claim 7
Dependent Claim
82 words
Radio apparatus in accordance with claim 1 including a resilient insulating member having a mounting portion with first and second flaps extending on opposite sides thereof, means securing said mounting portion to said one end of said frame member, said first flap extending over said chassis and said second flap extending over said battery opening in said frame member, said chassis being held in position within said frame member by said first flap extending thereover and engagement thereof by said cover member.
Claim 8
Dependent Claim
27 words
Radio apparatus in accordance with claim 6 wherein said first flap has ribs thereon for engaging said chassis to resiliently hold said chassis within said frame member.
Claim 9
Dependent Claim
24 words
Radio apparatus in accordance with claim 7 including resilient means on said frame structure engaged by said chassis when positioned on said frame structure.
Claim 10
Dependent Claim
41 words
Radio apparatus in accordance with claim 6 wherein said second flap extending over said battery opening has a free end which moves past said cover member in said second position, and flexes to permit movement of a battery through said opening.
