Abstract

A swivel display inclining structure used in a dual-use portable computer is disclosed to include a touch panel pivoted to the top surface of the base member of the portable computer, two spring members for supporting the touch panel in an inclined position relative to the base member of the portable computer to support the swivel display of the portable computer in an inclined open position, two latches slidably mounted on the base member of the portable computer for locking the touch panel to the base member of the portable computer in a received position, and an operating bar for pressing by the user to disengage the latches from the touch panel for enabling the touch panel to be forced outwards from the received position to the inclined position by the spring members for supporting the swivel display in the inclined open position.

Claims

1. A swivel display inclining structure used in a dual-use portable computer, which comprises a base member and a swivel display, said base member having a top surface, said swivel display being pivoted to said top surface and rotatable on said top surface and turnable relative to said base member, said swivel display inclining structure comprising:

a touch panel pivoted to said top surface of said base member, said touch panel having a locating groove in at least one lateral side thereof, and spring means adapted to impart a prestress to said touch panel to rotate relative to said base member to an inclined position;

at least one latch slidably mounted in said base member, said at least one latch having a front engagement end and a rear connecting end;

at least one spring member respectively connected between said at least one latch and said base member and adapted to force said front engagement end of said at least one latch engagement into said locating groove of said touch panel; and

an operating bar comprising at least one connecting end portion respectively coupled to the rear connecting end of said at least one latch, and a springy convex portion;

wherein when pressed said springy convex portion of said operating bar, said operating bar is forced to slide on said base member and to move said front engagement end of said at least one latch away from said locating groove of said touch panel and to unlock said touch panel, for enabling said touch panel to be upwardly rotated relative to said base member to said inclined position by the prestress of said spring means for supporting said swivel display.

2. The swivel display inclining structure as claimed in claim 1, wherein said operating bar further comprising at least one lever, said at least one lever having a middle part pivoted to said base member, a first end pivoted to said at least one connecting end portion of said operating bar, and a second end pivoted to said rear connecting end of said at least one latch.

3. The swivel display inclining structure as claimed in claim 1, wherein said at least one latch has a rear extension rod backwardly extending from said rear connecting end thereof;

said at least one spring member is respectively sleeved onto said rear extension rod of said at least one latch.

4. The swivel display inclining structure as claimed in claim 1, wherein said operating bar further comprising a press member provided at a top side of said springy convex portion thereof.

5. The swivel display inclining structure as claimed in claim 1, further comprising at least one guide member respectively fastened to said base member, said at least one guide member having a sliding groove for receiving said operating bar.

6. The swivel display inclining structure as claimed in claim 1, further comprising at least one guide member respectively fastened to said base member, said at least one guide member having a sliding groove for receiving said at least one latch.

7. The swivel display inclining structure as claimed in claim 1, wherein said base member further comprising a base plate mounted on said top surface thereof to secure said touch panel to said base member pivotally.

8. The swivel display inclining structure as claimed in claim 1, wherein said base member accommodates a keyboard.
