Abstract

The instant disclosure relates to an angle adjustable device, which includes: a base having a fixing member disposed thereon, where the fixing member has a fixing surface; a switch mechanism having a locking ring, a first gear, and a second gear, while at least one block protrudes from the inner surface of the locking ring, with the first gear having a contact incline slidingly abutted by the block, where the contact incline is defined with a first end and a second end, where the first gear is received by the locking ring and capable of meshing with the second gear; and a rotator having at least one connecting member connected to the second gear. The instant disclosure also discloses an electronic display unit using the same.

Claims

1. An angle adjustable device for electronic device, comprising:

a base having a fixing member disposed thereon, wherein the fixing member has a fixing surface, and a shaft is protruded from the fixing surface;

a switch mechanism arranged in close to the fixing member, the switch mechanism comprising a locking ring having at least one block arranged on the inner surface thereof, a first gear movably disposed on the shaft and having at least one contact incline formed in correspondence to the block, the contact incline having a first end and a second end, wherein the distance between the first end and the fixing surface is greater than the distance between the second end and the fixing surface, a second gear facing the first gear and selectively engaged by the first gear; and

a rotator connected to the switch mechanism, wherein the rotator includes at least one connecting member connected to the second gear.

2. The device of claim 1, wherein the first gear has a first tooth-bearing face and the second gear has a second tooth-bearing face, the first tooth-bearing face arranged adjacently to the second tooth-bearing face, and wherein the first gear has an outer surface having at least one slot formed thereon.

3. The device of claim 2, wherein the slot receives the contact incline and partially faces the fixing surface.

4. The device of claim 3, further comprising a shifter attached to an external surface of the locking ring, wherein the position of the block relative to the contact incline depends on the position of the shifter.

5. The device of claim 1, wherein the switch mechanism further includes an elastic member arranged between the fixing surface and the first gear.

6. The device of claim 2, wherein the slot receives the contact incline and does not face the fixing surface.

7. The device of claim 6, further comprising a shifter attached to an external surface of the locking ring, wherein the position of the block relative to the contact incline depends on the position of the shifter.

8. The device of claim 1, wherein the rotator can be rotated when the block is abutted against the first end, and the rotator is fixed when the block is abutted against the second end.

9. An electronic display unit, comprising:

a base having a fixing member disposed thereon, wherein the fixing member has a fixing surface, and a shaft is protruded from the fixing surface;

a switch mechanism arranged in close to the fixing member, wherein the switch mechanism includes a locking ring, a first gear, and a second gear, wherein the locking ring has at least one block formed on the inner surface thereof, wherein the first gear is movably disposed on the shaft and has at least one contact incline formed in correspondence to the block, the contact incline having a first end and a second end, wherein the distance between the first end and the fixing surface is greater than the distance between the second end and the fixing surface, wherein the first gear is selectively engageable with the second gear;

a rotator connected to the switch mechanism, wherein the rotator includes at least one connecting member connected to the second gear and a bracket; and

an electronic device disposed on the bracket.

10. The device of claim 9, wherein the first gear has a first tooth-bearing face and the second gear has a second tooth-bearing face, the first tooth-bearing face arranged adjacently to the second tooth-bearing face, wherein the first gear has an outer surface having at least one slot formed thereon.

11. The device of claim 10, wherein the slot receives the contact incline and partially faces the fixing surface.

12. The device of claim 11, further comprising a shifter attached to an external surface of the locking ring, wherein the position of the block relative to the contact incline depends on the position of the shifter.

13. The device of claim 9, wherein the switch mechanism further includes an elastic member arranged between the fixing surface and the first gear.

14. The device of claim 10, wherein the slot receives the contact incline and does not face the fixing surface.

15. The device of claim 14, further comprising a shifter attached to an external surface of the locking ring, wherein the position of the block relative to the contact incline depends on the position of the shifter.

16. The device of claim 9, wherein the rotator can be rotated when the block is abutted against the first end, and the rotator is fixed when the block is abutted against the second end.
