Anti-rotation mechanism for an electronic device
View Patent ↗An electronic device comprises a display member pivotally and rotationally coupled to a base member and an anti-rotation mechanism configured to be magnetically responsive to prevent rotational movement of the display member relative to the base member based on a position of the display member relative to the base member.
1. An electronic device, comprising:
a display member pivotally and rotationally coupled to a base member; and
an anti-rotation mechanism including a pin member that moves in response to a magnetic field to a position between the display member and base member to prevent rotational movement of the display member relative to the base member based on a position of the display member relative to the base member, wherein the rotational movement between the display member and the base member is prevented without either a latch or a locking mechanism securing the display member to the base member.
2. The electronic device of claim 1 , wherein the anti-rotation mechanism comprises multiple pin members extendable and retractable relative to both bottom and top sides of the base member.
3. The electronic device of claim 1 , wherein the pin member is moveable throughout a thickness of the base member to extend and retract through both top and bottom surfaces of the base member.
4. The electronic device of claim 3 , wherein the pin member moves to both retracted and extended positions without requiring a user to activate the anti-rotation mechanism.
5. The electronic device of claim 1 , wherein the pin member extends from a retracted position into a recess formed in at least one of the display member and the base member.
6. The electronic device of claim 1 further comprising, a friction clutch hinge assembly.
7. The electronic device of claim 6 , further comprising at least one recess formed in the display member for receiving the pin member therein.
8. The electronic device of claim 1 , wherein the anti-rotation mechanism comprises a magnet disposed in at least one of the display member and the base member.
9. The electronic device of claim 8 , wherein, in response to the magnetic field generated by the magnet, the pin member is extendable from a retracted position to couple together the base member and the display member.
10. An electronic device, comprising:
a hinge assembly configured to pivotally secure a display member in a fixed position relative to a latchless base member without either a latch or a locking mechanism securing the display member to the base member, the hinge assembly configured to enable rotational movement of the display member relative to the base member; and
an anti-rotation mechanism including a pin member that moves in response to a magnetic field to a position between the display member and the base member to prevent rotational movement of the display member relative to the base member based on a position of the display member relative to the base member.
11. The electronic device of claim 10 further comprising:
a magnet in the display member that moves the pin member from a retracted position to an extended position;
a spring that moves the pin member from the extended position to the retracted position.
12. The electronic device of claim 10 , wherein the hinge assembly is a friction clutch hinge assembly.
13. The electronic device of claim 12 , wherein the pin member is biased to the retracted position.
14. The electronic device of claim 10 , wherein the pin member extends from a retracted position into a recess formed in at least one of the display member and the base member.
15. The electronic device of claim 10 , wherein the anti-rotation mechanism comprises a magnet disposed in at least one of the display member and the base member.
16. The electronic device of claim 15 , wherein, in response to a magnetic field generated by the magnet, the pin member is extendable from a retracted position to prevent rotation of the display member relative to the base member.
17. An electronic device, comprising:
a hinge assembly that pivotally couples a display to a latchless base without either a latch or locking mechanism securing the display to the base; and
an anti-rotation mechanism including a pin member that moves in response to a magnetic field to a position between the display and base to prevent rotational movement of the display relative to the base.
18. The electronic device of claim 17 , wherein the anti-rotation mechanism comprises multiple pin members extendable and retractable relative to both bottom and top sides of the base.
19. The electronic device of claim 18 , wherein the pin member is moveable throughout a thickness of the base to extend and retract through both top and bottom surfaces of the base.
20. The electronic device of claim 17 , wherein the pin member moves to both retracted and extended positions without requiring a user to activate the anti-rotation mechanism.
