Abstract

The present creation is a video wall mount, including a first fixing rack, a second fixing rack, and a folding mechanism. The first fixing rack includes a locking piece and a magnet piece. The second fixing rack includes a rotating arm. The rotating arm having a hook and the locking piece are disposed to enable the hook to be hooked to the locking piece when the first fixing rack is located near the second fixing rack and enable the first fixing rack to be fixed at a position near the second fixing rack. When a television needs to be repaired or dismounted, a pushing force towards the second fixing rack is applied on the first fixing rack to enable the hook to rotate upward under the effect of a magnetic force from the magnet piece to leave a state of being hooked to the locking piece.

Claims

1. A video wall mount, comprising:

a first fixing rack, comprising a locking piece and a magnet piece;

a second fixing rack, disposed near a side of the first fixing rack, the second fixing rack comprising a rotating arm, the rotating arm comprising a pivotal joint, a hook, and a guiding slope, the pivotal joint being pivotally connected on the second fixing rack, the guiding slope being located between the pivotal joint and the hook, the rotating arm being rotatable about the pivotal joint being an axis to enable the hook to be selectively hooked to or unhooked from the locking piece; and

a folding mechanism, connected between the first fixing rack and the second fixing rack;

wherein;

a linear segment defined between the locking piece and the pivotal joint forms a reference line, and the magnet piece is fixedly disposed on the first fixing rack and located above the reference line;

wherein when the hook of the rotating arm is selectively hooked to the locking piece, the first fixing rack is movable more easily relative to the second fixing rack, so that the locking piece abuts the guiding slope and moves relatively towards the pivotal joint, so as to further drive the rotating arm to rotate upward to a near-magnet point, the near-magnet point refers to that the rotating arm rotates upward to approach the magnet piece and is subject to a specific magnetic attraction force, and the specific magnetic attraction force is sufficient to counteract a part of the gravitation of the rotating arm to extend the time for the rotating arm to rotate and fall.

2. The video wall mount according to claim 1, wherein the first fixing rack and the second fixing rack are parallel to each other.

3. The video wall mount according to claim 2, wherein the folding mechanism is formed by a four-bar linkage mechanism.

4. The video wall mount according to claim 1, wherein the magnet piece of the first fixing rack is a permanent magnet.

5. The video wall mount according to claim 1, wherein the guiding slope of the rotating arm is a linear slope.

6. The video wall mount according to claim 1, wherein the second fixing rack further comprises at least one stop piece to stop the rotating arm to avoid excessive rotation of the rotating arm.

7. The video wall mount according to claim 6, wherein the number of the at least one stop piece is two, one of which is an upper stop piece, and the other is a lower stop piece.

8. The video wall mount according to claim 1, wherein the folding mechanism comprises a reset spring for providing a preload to enable the first fixing rack to moving away from the second fixing rack.

9. The video wall mount according to claim 1, wherein the rotating arm is directed by the specific magnetic attraction force till the rotating arm is touched by the magnet piece.
