Abstract

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.
