CLAIMS

1. A hinge assembly, comprising:

a first mounting plate having a first female receptacle therein defining a first axis; a second mounting plate having a second female receptacle therein defining a second axis;

a female friction hinge member having a recess defined therein and an elongated pin for mounting within the first female receptacle; and

a male friction hinge member having an elongated pin for mounting within the second female receptacle, the male friction hinge member further including an elongated extension member coordinatedly coupled within the recess of the female friction hinge member so that the female friction hinge member and male friction hinge member rotate in unison.

2. The hinge assembly of claim 1, wherein the elongated extension of the male friction hinge member is slidably coupled within the recess of the female friction hinge member so that the male and female friction hinge members cooperatively slide in a radial direction to the first and second axes and towards and away from each other.

3. The hinge assembly of any of claims 1-2, wherein the extension member is frictionally engaged within the recess of the female friction hinge member.

4. The hinge assembly of any of claims 1-3, wherein the female friction hinge member and male friction hinge member rotate around parallel axes and wherein the elongated extension member is keyed so as to allow radial movement with respect to the first and second axis between the female friction hinge member and the male friction hinge member with a stop to prevent separation thereof.

5. The hinge assembly of any of claims 1-4, wherein the first female receptacle of the first mounting plate is a slotted clip into which the elongated pin of the female friction hinge member is inserted with a friction fit.

6. The hinge assembly of any of claims 1-5, wherein the elongated extension member has a slot therein and the female friction hinge member has a pin so as to form a pin-and-slot joint there between.

7. The hinge assembly of any of claims 1-6, wherein the elongated extension member has first and second sides that are asymmetrical and the recess is shaped to match the first and second sides so that the elongate extension member can slide within the recess.

8. The hinge assembly of any of claims 1-7, wherein the first or second female receptacles are one of the following: a slotted clip, a question-mark band, a roll pin band, or a tapered shaft.

9. A method of coupling first and second devices, comprising:

providing a first mounting plate of a male friction hinge coupled to the first device, the first mounting plate having a first female receptacle coupled thereto;

providing a second mounting plate of a female friction hinge coupled to the second device, the second mounting plate having a second female receptacle coupled thereto; inserting a pin of a male friction hinge into the first female receptacle of the first mounting plate with a friction fit, wherein the male friction hinge includes a coupling portion including an elongated extension member;

inserting a pin of a female friction hinge into the second female receptacle of the second mounting plate with a friction fit, the female friction hinge including a coupling portion with a recess therein; and

inserting the elongated extension member of the male friction hinge to the recess of the coupling portion of the female friction hinge to couple the first friction hinge to the second friction hinge.

10. The method of claim 9, wherein the male friction hinge rotates in unison with female friction hinge due to the coupling of the elongated extension member to the recess of the female friction hinge.

11. The method of any of claims 9-10, wherein the elongated extension member fits within the recess of the female friction hinge with a friction fit.

12. The method of any of claims 9-11, wherein the male friction hinge and female friction hinge have a geared cooperation to stop the first device at any relative rotational angle to the second device.

13. The method of any of claims 9-12, wherein the elongate extension member has two sides that are asymmetric with one of the two sides keyed to fit within a notch in the coupling portion of the female friction hinge.

14. The method of any of claims 9-13, wherein the elongated extension member includes a slot and the female friction hinge includes a pin so as to form a pin-and- slot joint there between.

15. The method of any of claims 9-14, wherein the elongated extension member slides within the recess within the coupling portion of the female friction hinge.
