Abstract

A mounting cradle for mounting a portable cellular telephone in a vehicle. The cradle is adjustable in width, length and height, by a single pair of fasteners, to accommodate portable cellular telephones of varying sizes. The cradle and an associated cradle mount enable the telephone to be selectively and removably positioned at an angular orientation extending through a full 360 degrees, and also allow the cradle and telephone to be tilted through a substantial angle. The cradle has an adjustable compression spring, characterized by two levels of spring tension, for accommodating varying shock and vibration conditions.

Claims

1. A cradle for a portable telephone, comprising:

an elongate base plate;

a pair of first and second side plates affixed to said elongate base plate;

inwardly directed compression spring means affixed to at least one side plate; and

fastening means for fastening said elongate base plate to a cradle mount to accommodate a portable telephone, wherein said elongate base plate comprises slot means therein for adjusting the position of said elongate base plate.

2. The invention of claim 1 wherein said slot means comprises longitudinal slot means for providing longitudinal adjustment of said elongate base plate.

3. The invention of claim 1 wherein at least one of said side plates comprises an integral upright side segment and an integral base segment extending transversely.

4. The invention of claim 3 wherein said upright side segment and said base segment of said side plate are at approximately a right angle to each other.

5. The invention of claim 3 wherein at least one said base segment of said side plates comprises slot means therein for adjusting the position of said side plates.

6. The invention of claim 5 wherein said slot means comprises transverse slot means for providing transverse adjustment of said side plates relative to each other.

7. The invention of claim 3 wherein:

said elongate base plate comprises first slot means therein;

at least one said base segment of said side plates comprises second slot means corresponding thereto; and

said fastening means extends through said first slot means in said elongate base plate and through said second slot means in said base segment of said side plate to accommodate cellular telephones of varying sizes and shapes.

8. The invention of claim 7 wherein said first slot means comprises longitudinal slot means for providing longitudinal adjustment of the relative positioning of said side and elongate base plates.

9. The invention of claim 7 wherein said second slot means comprises transverse slot means for providing transverse adjustment of the relative positioning of said side and elongate base plates.

10. The invention of claim 7 wherein said first slot means comprises longitudinal slot means and said second slot means comprises transverse slot means for providing longitudinal and transverse adjustments of the relative positioning of said side and elongate base plates.

11. The invention of claim 7 wherein said fastening means comprises a nut plate and at least one fastener engageable with said nut plate, said fastener passing through said first slot means in said elongate base plate and through said second slot means in said base segment of said side plate so as to provide for adjustably affixing said elongate base plate and said side plate to said nut plate, and wherein said nut plate further comprises means for fastening said nut plate to the cradle mount.

12. The invention of claim 1 wherein said fastening means comprises threaded fasteners.

13. The invention of claim 1 wherein said compression spring means comprises at least one pair of opposing compression springs, with at least one compression spring affixed to each of said side plates.

14. The invention of claim 1 wherein said compression spring means is affixed to said side plate by at least one fastener engaged in an upright slot in one of said side plates, whereby the height of said compression spring means may be selectively adjusted.

15. The invention of in claim 1 wherein said compression spring means comprises dual spring head means.

16. The invention of claim 15 wherein said spring head means is convexly curved to prevent edges of said spring heads from engaging a telephone housing.

17. The invention of claim 15 wherein said spring head means comprises two levels of spring tension resulting from two radii of curvature, said spring head means comprising a first radius of curvature extending away from said side plates so as to provide a relatively low level of spring tension, and said spring head means further comprising a curled end having a second, smaller radius of curvature to provide a higher level of spring tension.

18. The invention of claim 1 wherein said base plate comprises foot extension means to support the portable telephone.

19. The invention of claim 18 wherein said foot extension means comprises a pair of spaced apart transverse extending feet to support the portable telephone while also allowing the telephone to be connected to an electrical power source.

20. The cradle defined in claim 1 wherein said base plate comprises one or more elongate elastomeric pads adhered thereto.
