Abstract

A telephone cradle has ratcheting, sliding walls which engage a telephone and hold it securely. A ratchet release button, operable by the same hand that grasps the telephone, releases the sliding walls when it is desired to lift and use the telephone. The walls are spring-loaded to open and are driven to move equally in opposite directions. A friction plate dampens the motion of the sliding walls. Resilient pads disposed on the sliding walls securely hold the telephone. The cradle may be flexibly mounted to a vehicle.

2. The cradle of claim 1, wherein said ratchet means comprises a ratchet gear and a pawl engaging said ratchet gear;

and said means for releasing releases said pawl from engaging said ratchet gear.

3. The cradle of claim 1, wherein one or more of said walls has a resilient pad disposed on a surface facing the other wall, said one or more resilient pads being compressible at least the distance of one successive ratchet position of said sliding wall.

6. The cradle of claim 1, wherein said means for holding comprises ratchet means holding both said walls in said several, successive positions toward each other and wherein said means for releasing comprises means for releasing said ratchet means.

4. A cradle for various sizes of telephone means, said cradle comprising:

a base;

first and second walls attached to said base;

at least one of said walls slidably attached to said base, said sliding wall disposed opposite the other wall and disposed to slide toward and away from said other wall;

means for holding said sliding wall at several, successive positions against various sizes of said telephone means;

spring means disposed to urge said sliding wall away from said other wall; and

means for releasing said means for holding, thereby allowing said spring means to move said sliding wall away from said other wall;

wherein both said walls are slidably disposed with respect to said base and said means for holding comprises ratchet means having several teeth, said ratchet means adapted to hold both of said walls in said several, successive positions against said telephone means when said telephone means is disposed in said cradle; and

said means for releasing releases both said walls from against said telephone means.

5. The cradle of claim 4, wherein one or more of said walls has a resilient pad disposed on a surface facing the other wall, said one or more resilient pads providing a resilience greater than the successive distance between the successive positions of said sliding wall.

7. A cradle for telephone means, said cradle comprising:

a base;

first and second walls attached to said base;

at least one of said walls slidably attached to said base, said sliding wall disposed opposite the other wall and disposed to slide toward and away from said other wall;

means for holding said sliding wall against said telephone means when said telephone means is disposed in said cradle;

means for releasing said sliding wall from against said telephone means;

wherein said means for holding said sliding wall against said telephone means, comprises ratchet means for holding said sliding wall at successive positions with respect to said other wall;

wherein said ratchet means comprises a rotating ratchet gear and wherein said cradle includes damping means disposed to damp the motion of each said slidably attached wall, when said wall is released.

8. A cradle for telephone means, said cradle comprising:

a base;

first and second walls attached to said base;

at least one of said walls slidably attached to said base, said sliding wall disposed opposite the other wall and disposed to slide toward and away from said other wall;

means for holding said sliding wall against said telephone means when said telephone means is disposed in said cradle;

means for releasing said sliding wall from against said telephone means;

wherein said means for holding said sliding wall against said telephone means, comprises ratchet means for holding said sliding wall at successive positions with respect to said other wall;

wherein said ratchet means comprises a rotating gear and a pawl engaging said rotating gear;

wherein said means for releasing comprises means for disengaging said pawl from said rotating gear;

wherein said cradle further includes a coordinating gear disposed on a hub with said rotating gear; and

wherein said cradle further includes two linear gears, each said linear gear fixedly attached to a respective one of said sliding walls, said linear gears engaging said coordinating gear.

9. A cradle for telephone means, said cradle comprising:

a base;

first and second walls slidably attached to said base;

said walls disposed opposite each other and disposed to slide toward and away from each other;

means for holding said sliding walls against said telephone means when said telephone means is disposed in said cradle;

means for releasing both said sliding walls from against said telephone means; and

wherein said means for holding comprises ratchet means holding both said walls in successive positions toward each other; and

wherein said means for releasing comprises means for releasing said ratchet means; and

wherein said ratchet means comprises a ratchet assembly which comprises a ratchet gear and a pawl engaging said ratchet gear; and

wherein said cradle includes a coordinating gear; and

wherein said ratchet gear is connected to said coordinating gear, and wherein said cradle includes two linear gears, one of said linear gears fixedly disposed with respect to one of said walls and the other of said linear gears fixedly disposed with respect to the other of said walls, said linear gears being disposed on opposite sides of said coordinating gear, and wherein said coordinating gear engages said linear gears, whereby said walls move equally and in opposite directions with respect to said base.

10. The cradle of claim 9, wherein said cradle includes damping means for damping the motion of said walls.

11. A cradle for telephone means, said cradle comprising:

a base;

first and second walls slidably disposed with respect to said base, said walls being oppositely disposed with respect to each other and disposed to slide toward and away from each other;

means for holding said sliding walls against said telephone means when said telephone means is disposed in said cradle;
