  • Patent number: 11448294
    Abstract: A linkage mechanism includes a pivoting assembly, a cam, a sliding assembly and at least one linkage. The cam pivots coaxially with the rotating axis of the pivoting assembly. A leaning element is located on one side of the cam. A sliding frame pivots the leaning element and has at least one limiting area. The linkage includes a main body portion, a first linkage portion protruded beyond the limiting area and a second linkage portion. When the pivoting assembly drives the cam to pivot from a first position to a second position, the cam pushes against the leaning element to slide the sliding frame in a first direction relative to a plate, and the limiting area interferes with the first linkage portion of the linkage to rotate the main body portion in a first clock direction to allow the second linkage portion to provide a thrust in a second direction.

  • Patent number: 10915150
    Abstract: A linkage mechanism includes a pivoting assembly, a cam, a sliding assembly, and a linkage assembly. The cam pivots coaxially with the rotating axis. The sliding assembly is assembled on a plate member and has a leaning surface and a sliding slot. The linkage assembly includes a linkage passing through the sliding slot and a carrier base including at least one bump and fastened to the linkage. When the pivoting assembly drives the cam to pivot from a first position to a second position, the cam pushes against the leaning surface to slide the sliding assembly relative to the plate member in a first direction, and the linkage rotates in the sliding slot to drive the carrier base to move in a second direction, and the bump gradually enters into a cavity of a frame from leaning the frame to move the frame in a third direction.

  • Patent number: 10208842
    Abstract: A linkage mechanism includes a pivot assembly, a gear assembly, and a linkage assembly. The pivot assembly pivots around a first rotation axis. The gear assembly is pivoted with the pivot assembly and moves in conjunction with the pivot assembly. The gear assembly includes a cam, and the cam pivots around a second rotation axis. The second rotation axis is not parallel to the first rotation axis. The linkage assembly is disposed at a side of the gear assembly and contacts the cam. When the pivot assembly drives the gear assembly to pivot, the linkage assembly abuts against the cam to produce a relative movement with the cam.
