Laptop dual-swivel hinges
View Patent ↗In a convertible notebook/tablet computer with a dual-swivel hinge, an arrangement for communicating to a user a preferred rotational direction for pivoting about a z-axis, entirely without wiring or lights and in a manner such that at most only one rotational direction is communicated at a time. Preferably, this is accomplished via one or more windows, disposed on a surface of the hinge, that permit an arrow to be visible in accordance with a preferred rotational direction that a user needs to pivot the monitor/lid with respect to the keyboard based on the rotational direction originally traversed.
1. A computer comprising:
a lid portion;
a base portion;
a dual-swivel hinge interconnecting said lid portion and said base portion, said hinge comprising:
a first portion which is rotationally fixed with respect to said lid portion; and
a second portion which is rotationally fixed with respect to said base portion;
said first portion being rotationally displaceable with respect to said second portion between a first orientation and a second orientation about a central axis of said hinge, the first and second orientations differing in rotational position with respect to the central axis;
a marking arrangement comprising:
a rotationally displaceable arrow ring comprising a single flange having disposed thereon a first marking associated with the first orientation; and a second marking associated with the second orientation;
said single flange being selectively displaced to avail said first marking while said first portion is in the first orientation and avail said second marking while said first portion is in the second position.
2. The computer according to claim 1 , wherein said computer comprises a laptop computer.
3. The computer according to claim 2 , wherein:
said laptop computer comprises a convertible notebook/tablet computer;
the first orientation corresponds to one of: a notebook mode of said laptop computer and a tablet mode of said laptop computer;
the second orientation corresponds to the other one of: a notebook mode of said laptop computer and a tablet mode of said laptop computer.
4. The computer according to claim 1 , wherein said lid portion comprises a monitor and said base portion comprises a keyboard.
5. The computer according to claim 1 , wherein the first and second orientations are offset from one another by a rotational distance of about 180 degrees.
6. The computer according to claim 1 , wherein said single flange is rotatably mounted about the central axis.
7. The computer according to claim 6 , further comprising:
means for transferring rotational displacement from said first portion to said single flange; and
a stop element rotationally fixed with respect to said second portion;
said stop element acting to inhibit rotational displacement of said single flange relative to said first portion such that:
while said first portion is in the first orientation, said first marking is availed and said second marking is not availed; and
while said first portion is in the second orientation, said second marking is availed and said first marking is not availed.
8. The computer according to claim 1 , wherein:
said first marking comprises a first arrow; and
said second marking comprises a second arrow;
said first and second arrows each corresponding to a predetermined return direction of rotational displacement when said first portion is in said second orientation.
9. The computer according to claim 8 , wherein said first and second arrows point in opposite rotational directions.
10. A dual-swivel hinge comprising:
a first portion; and
a second portion;
said first portion being rotationally displaceable with respect to said second portion between a first orientation and a second orientation about a central axis of said hinge, the first and second orientations differing in rotational position with respect to the central axis;
a marking arrangement comprising:
a view medium;
a rotationally displaceable arrow ring comprising a single flange having disposed thereon a first marking associated with the first orientation and a second marking associated with the second orientation; said rotationally displaceable arrow ring
avails said first marking to said view medium while said first portion is in the first orientation; and
avails said second marking to said view medium while said first portion is in the second orientation.
11. The hinge according to claim 10 , wherein the first and second orientations are offset from one another by a rotational distance of about 180 degrees.
12. The hinge according to claim 10 , wherein:
said hinge comprises a cover surface; and
said view medium comprises an aperture rendering visible an element disposed below said cover surface.
13. The hinge according to claim 12 , wherein:
said single flange avails said first marking to said view medium while said first portion is in the first orientation; and
said single flange further avails said second marking to said view medium while said first portion is in the second orientation.
14. The hinge according to claim 13 , wherein:
said single flange is rotatably mounted about the central axis;
said availing arrangement further comprises:
means for transferring rotational displacement from said first portion to said single flange; and
a stop element rotationally fixed with respect to said second portion;
said stop element acting to inhibit rotational displacement of said single flange relative to said first portion such that:
while said first portion is in the first orientation, said first marking is availed to said view medium and said second marking is not availed to said view medium; and
while said first portion is in the second orientation, said second marking is availed to said view medium and said first marking is not availed to said view medium.
15. The hinge according to claim 10 , wherein:
said first marking comprises a first arrow; and
said second marking comprises a second arrow;
said first and second arrows each corresponding to a predetermined return direction of rotational displacement when said first portion is in said second orientation;
said first and second arrows pointing in opposite rotational directions.
