Abstract

A redundant hinge element and a hinge assembly made from the redundant hinge element that are adapted to provide pivotal connection between casings of a notebook computer, laptop computer, handheld computer, palmtop computer, or other appliance.

Claims

1. A hinge device for pivotally connecting first and second parts of a casing, comprising:

(a) a plurality of interlocking, redundant hinge elements that are assembled together to create a hinge assembly; and

(b) each of the redundant hinge elements comprised of a cylindrical portion and a cylindrical slot portion that is partially open to accept the cylindrical portion of an adjacent, interlocking, redundant hinge element, wherein the cylindrical slot portion includes one or mote retention wings;

(c) wherein each end of the hinge assembly is adapted for connection to one of the first and second parts of the casing such that rotation of the hinge assembly causes pivotal motion between the first and second parts of the casing.

2. The hinge device of claim 1, wherein the cylindrical portion includes one or more cable raceways.

3. The hinge device of claim 1, wherein a connecting portion between the cylindrical portion and the cylindrical slot portion includes one or more pass-thru slots.

4. The hinge device of claim 1, wherein the hinge assembly pivotally the connects first and second parts of the casing.

5. The hinge device of claim 4, wherein the casing comprises a casing selected from a group comprising a notebook computer casing, a laptop computer casing, a handheld computer casing, and a palmtop computer casing.

6. The hinge device of claim 4, wherein the first part comprises a base of the casing and the second part comprises a lid of the casing.

7. The hinge device of claim 6, wherein the hinge assembly allows the lid to be tilted and positioned with respect to the base in a range of inclinations between a closed position and a maximum tilt position.

8. The hinge device of claim 1, wherein the cylindrical portion of a first redundant hinge element is substantially in co-axial alignment with the cylindrical slot portion of a second redundant hinge element when seated in the cylindrical slot portion of the second redundant hinge element.

9. The hinge device of claim 8, wherein the cylindrical portion of the first redundant hinge element has an axis of rotation of approximately 120 degrees when seated in the cylindrical slot portion of the second redundant hinge element.

10. The hinge device of claim 1, wherein the hinge assembly allows for more than 180 degrees of rotation between the first and second parts.

11. The hinge device of claim 10, wherein the hinge assembly allows for 360 degrees of rotation between the first and second parts.

12. A hinge assembly for pivotally connecting a base and lid of a casing, wherein the hinge assembly is comprised of interlocking hinge elements, each of the hinge elements comprising of a cylindrical portion and a cylindrical slot portion that is partially open to accept the cylindrical portion of another hinge element, wherein the cylindrical slot portion of each of the interlocking hinge elements includes means for retaining the cylindrical portion of another hinge element, and the hinge assembly connects the base to the lid in a manner that permits pivotal rotation of the base and lid relative to each other.

13. The hinge assembly of claim 12, wherein the cylindrical portion of a first hinge element is substantially in co-axial alignment with the cylindrical slot portion of a second redundant hinge element when seated in the cylindrical slot portion of the second hinge element.

14. The hinge assembly of claim 13, wherein the cylindrical portion of the first hinge element has an axis of rotation of approximately 120 degrees when seated in the cylindrical slot portion of the second redundant hinge element.

15. The hinge assembly of claim 12, wherein the hinge assembly allows for more than 180 degrees of rotation between the base and lid.

16. The hinge assembly of claim 15, wherein the hinge assembly allows for 360 degrees of rotation between the base and lid.

17. A hinge element for a hinge assembly comprising a cylindrical portion and a cylindrical slot portion that is partially open to accept the cylindrical portion of another hinge element, wherein the cylindrical slot portion includes one or more retention wings for retaining the accepted cylindrical portion of another hinge element within the cylindrical slot portion.

18. The hinge element of claim 17, wherein a plurality of interlocking hinge elements are assembled together to create the hinge assembly.

19. The hinge element of claim 17, wherein the cylindrical portion includes one or more cable raceways.

20. The hinge element of claim 19, wherein a connecting portion between the cylindrical portion and the cylindrical slot portion includes one or more pass-thru slots.

21. The hinge element of claim 17, wherein the cylindrical portion of the other hinge element is substantially in co-axial alignment with the cylindrical slot portion of the hinge element when seated in the cylindrical slot portion of the hinge element.
