Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
An adapter assembly for receiving a telephone set in rigid attachment thereto, said adapter assembly being adapted to be releasibly secured to a wall-mounted receptacle plate having a pair of mounting studs extending outwardly therefrom and an electrical jack for making connections to said telephone set, said adapter assembly comprising: a unitary base plate having a front surface for receiving said telephone set and a recessed wall area joined with said front surface, said recessed wall area including first and second apertures adapted to receive said mounting studs and a third aperture for receiving an electrical plug; an electrical plug slidably supported in said third aperture; and a locking bar slidably supported by said base plate adjacent to one of said stud receiving apertures for selectively locking said base plate to said mounting studs.
Claim 2
Dependent Claim
134 words
An adapter assembly for receiving a telephone set in rigid attachment thereto, said adapter assembly being adapted to be releasibly secured to a wall-mounted receptacle plate having a pair of mounting studs extending outwardly therefrom and an electrical jack for making connections to said telephone set, said adapter assembly comprising: a unitary base plate having a front surface for receiving said telephone set and a recessed wall area joined with said front surface, said recessed wall area including first and second apertures adapted to receive said mounting studs and a third aperture for receiving an electrical plug; an electrical plug slidably supported in said third aperture; and a locking bar slidably supported by said base plate adjacent to one of said stud receiving apertures for selectively locking said base plate to said mounting studs.
Claim 3
Dependent Claim
55 words
The adapter assembly as claimed in claim 1, wherein said mounting studs include flanged ends which cooperate with wall portions adjacent their respective apertures such that when said adapter assembly is mounted to said wall plate said adjacent wall portions extend behind said flanges to prevent removal of said adapter assembly from said mounting plate.
Claim 4
Dependent Claim
42 words
The adapter assembly as claimed in claim 2, wherein said locking bar is normally biased such that said bar prevents sufficient movement between said adapter assembly and said wall plate to allow said flanges to become disengaged from said adjacent wall portions.
Claim 5
Dependent Claim
62 words
The adapter assembly as claimed in claim 3, wherein said locking bar includes a slot in one edge thereof whereby said locking bar may be moved from the normally biased position such that the recessed area aligns with said cooperating stud to allow the adapter assembly to be moved relative to said studs to free said flange from said adjacent wall portions.
Claim 6
Dependent Claim
25 words
The adapter assembly as claimed in claim 1, wherein said recessed wall area is positioned intermediate the front and rear surfaces of said base plate.
