Abstract

Abstract The support has a recess that accommodates the earpiece of the handset, the recess being bounded by a locking wall at the upper end thereof, a locking wall at each side, and a ledge at the lower end. A hookswitch plunger protrudes through the ledge, and the upper surface of the plunger together with the upper locking wall of the recess interact with the earpiece to secure the handset to the support when the lower end of the handset is tilted out from the support. In addition, the two side locking walls of the recess interact with the earpiece to secure the handset to the support when the lower end of the handset is tilted parallel to the support.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 143 words
A wall support for a telephonE handset having a protuberant earpiece that includes a face that is placed against the user''s ear and an upper and lower surface, the telephone support comprising: a housing having a recess therein, the recess including an inclined backwall, the upper end of which is farther to the rear than the lower end; a first locking surface at the upper end of the recess; and a second locking surface at the lower end of the recess, the second locking surface extending at about the same angle with respect to the backwall of the recess that the lower surface of the earpiece extends with respect to the face of the earpiece, and the second locking surface being spaced from the first locking surface a slightly greater distance than the distance between the upper and lower surfaces of the earpiece.
Claim 2
Dependent Claim 143 words
A wall support for a telephonE handset having a protuberant earpiece that includes a face that is placed against the user''s ear and an upper and lower surface, the telephone support comprising: a housing having a recess therein, the recess including an inclined backwall, the upper end of which is farther to the rear than the lower end; a first locking surface at the upper end of the recess; and a second locking surface at the lower end of the recess, the second locking surface extending at about the same angle with respect to the backwall of the recess that the lower surface of the earpiece extends with respect to the face of the earpiece, and the second locking surface being spaced from the first locking surface a slightly greater distance than the distance between the upper and lower surfaces of the earpiece.
Claim 3
Dependent Claim 213 words
A wall support for a telephone handset having a protuberant earpiece that includes an upper and lower surface and a face extending therebetween, the telephone support comprising: a housing having a recess therein at the upper end thereof, the recess being bounded at its lower end by a ledge and at its upper end by an upper locking wall, and the recess having an inclined backwall extending between the ledge and the upper locking wall, the upper end of the backwall being farther to the rear than the lower end; and a plunger protruding through an opening in the ledge, the plunger being movable between an extended position and a depressed position, the earpiece of the handset engaging the plunger and moving it to the depressed position when the handset is positioned on the support, the plunger having an upper surface that extends at about the same angle with respect to the backwall of the recess that the lower surface of the earpiece extends with respect to the face of the earpiece, and the upper surface of the plunger when the plunger is in a depressed position being spaced from the upper locking wall of the recess a slightly greater distance than the distance between the upper and lower surfaces of the earpiece.
Claim 4
Dependent Claim 213 words
A wall support for a telephone handset having a protuberant earpiece that includes an upper and lower surface and a face extending therebetween, the telephone support comprising: a housing having a recess therein at the upper end thereof, the recess being bounded at its lower end by a ledge and at its upper end by an upper locking wall, and the recess having an inclined backwall extending between the ledge and the upper locking wall, the upper end of the backwall being farther to the rear than the lower end; and a plunger protruding through an opening in the ledge, the plunger being movable between an extended position and a depressed position, the earpiece of the handset engaging the plunger and moving it to the depressed position when the handset is positioned on the support, the plunger having an upper surface that extends at about the same angle with respect to the backwall of the recess that the lower surface of the earpiece extends with respect to the face of the earpiece, and the upper surface of the plunger when the plunger is in a depressed position being spaced from the upper locking wall of the recess a slightly greater distance than the distance between the upper and lower surfaces of the earpiece.
Claim 5
Dependent Claim 46 words
A telephone support as in claim 2 wherein the angle at which the upper locking wall extends with respect to the backwall is about the same as the angle at which the upper surface of the earpiece extends with respect to the face of the earpiece.
Claim 6
Dependent Claim 24 words
A telephone support as in claim 2 wherein the upper surface of the plunger conforms in shape to the lower surface of the earpiece.
Claim 7
Dependent Claim 22 words

Claim 8
Dependent Claim 234 words
A wall support for a telephone handset having a protuberant earpiece that includes an upper and lower surface, a pair of planar side surfaces, and a face, the telephone support comprising: a housing having a recess therein at the upper end thereof, the recess being bounded by a ledge at its lower end, a locking wall at its upper end, a locking wall at each side, and an inclined backwall at the rear, the upper end of the backwall being farther to the rear than the lower end, the side locking walls extending nearly perpendicular to the backwall and being spaced slightly farther apart than the side surfaces of the earpiece; and a plunger protruding through an opening in the ledge, the plunger being movable between an extended position and a depressed condition, the earpiece of the handset engaging the plunger and moving it to the depressed condition when the handset is positioned on the support, the plunger having an upper surface that extends at about the same angle with respect to the backwall of the recess that the lower surface of the earpiece extends with respect to the face of the earpiece, and the upper surface of the plunger when the plunger is in a depressed position being spaced from the upper locking wall of the recess a slightly greater distance than the distance between the upper and lower surfaces of the earpiece.
Claim 9
