Abstract

A synchronized multiple-angle rotatable dual-pivot structure includes a first pivot, a second pivot, a plurality of connection members, and a support frame. The first pivot and the second pivot are each provided with an installation slot. The connection members are of the same length and each has two ends respectively and movably mounted in the installation slots of the first pivot and the second pivot. The support frame has two ends respectively coupled to the first pivot and the second pivot. The connection members are connected between the first pivot and the second pivot so that when one of the first pivot and the second pivot is rotated, forces are induced between the first pivot and the second pivot to mutually pull and push each other so that synchronized rotation can be achieved in an easy and effortless manner and the rotation angle can reach at least 180 degrees.

Claims

1. A synchronized multiple-angle rotatable dual-pivot structure, comprising:

a first pivot, which comprises a first mounting section, the first mounting section being adapted to be mounted to one component of an article to be assembled, the first pivot comprising at least one first installation slot;

a second pivot, which comprises a second mounting section, the second mounting section being adapted to be mounted to another component of the article to be assembled, the second pivot comprising at least one second installation slot;

at least two connection members, which are of the same length, the connection members each having two ends rotatably and respectively mounted in one of said at least one first installation slot and one of said at least one second installation slot; and

a support frame, which has two end portion rotatably and respectively coupled to the first pivot and the second pivot.

2. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1, wherein the first mounting section comprises at least one fixing hole formed therein.

3. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1, wherein the second mounting section comprises at least one fixing hole formed therein.

4. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1 further comprising a plurality of axles, wherein the first installation slot and the second installation slot each comprises a plurality of axle holes, the axles being set through opposite ends of each of the connection members and in coupling engagement with the axle holes so as to have the ends of each of the connection members rotatably and respectively coupled in the first installation slot and the second installation slot.

5. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1, wherein the first pivot comprises an elastic plate and a washer fit thereto and the first pivot comprises a threaded section, a nut being screwed to the threaded section, so that the nut securely fix the support frame, the elastic plate, and the washer.

6. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1, wherein the second pivot comprises an elastic plate and a washer fit thereto and the second pivot comprises a threaded section, a nut being screwed to the threaded section, so that the nut securely fix the support frame, the elastic plate, and the washer.

7. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1, wherein the first pivot and the second pivot each comprise a planar face formed thereon.

8. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1 further comprising a plurality of axles, the axles being mounted in the first installation slot and the second installation slot, the ends of each of connection members being respectively provided with two fitting openings, the fitting openings being each in the form of a notch to allow the fitting opening to fit over a corresponding one of the axles, whereby the two ends of each of the connection members are respectively and rotatably received in the first installation slot and the second installation slot.

9. The synchronized multiple-angle rotatable dual-pivot structure according to claim 1, wherein the connection members are arranged in a number of two in each of the first installation slot and the second installation slot.
