A quick-release structure for a screen and a stand

Abstract

A quick-release structure for a screen and a bracket, respectively disposed on the screen end and the bracket end, includes: a hook fastener disposed on the screen end; a fixing member disposed on the bracket end; a pressing member pivotally disposed on the fixing member and having a first pivot end and an operating end; the first pivot end is disposed on the pressing member, and the operating end is located on the opposite side of the first pivot end; and a fastening member having a hook that selectively engages with the hook fastener and disposed on the second pivot end of the pressing member; wherein the fastening member has an unlocked state and a locked state; in the locked state, the operating end moves downward to lock the fastening member onto the hook fastener on the screen end, thereby restricting the relative movement between the screen end and the bracket end; and in the unlocked state, the operating end moves upward to pivot the fastening member relative to the pressing member, thereby disengaging the fastening member from the hook fastener on the screen end.

Claims

1. A quick-release structure for a screen and a stand, respectively disposed on a screen end and a stand end, comprising: A hook fastener is disposed at the end of the screen; A fastener is disposed at one end of the bracket; A clamping member, pivotally mounted on the fixing member, has a first pivot end and an operating end; the first pivot end is disposed on both arms of the clamping member, and the operating end is located on the opposite side of the first pivot end; and a fastening member, which is a T-shaped structure, has a rod and a crossbar, the top of the rod forming a hook, the hook selectively engaging with a hook fastener, the crossbar being pivotally mounted on a second pivot end on one of the two arms of the clamping member; wherein the fastening member has an unlocked state and a locked state; in the locked state, the operating end moves downward to lock the fastening member onto the hook fastener at the screen end, thereby restricting the relative movement between the screen end and the bracket end; and in the unlocked state, the operating end moves upward to pivot the fastening member relative to the clamping member, thereby disengaging the fastening member from the hook fastener at the screen end.

2. The quick-release structure of screen and stand as described in claim 1, wherein the screen is a screen applicable to an all-in-one computer, a point of sale (POS) system, a desktop computer, a server, or an industrial computer.

3. The quick-release structure for screen and bracket as described in claim 1, wherein the bracket end is a desktop bracket or a wall-mounted bracket.

4. The quick-release structure for screen and bracket as described in claim 1, wherein the hook and the fastener are secured by a locking device or are integrally formed and respectively disposed on the screen end and the bracket end.

5. The quick-release structure for screen and bracket as described in claim 1, wherein the hook is a protrusion or a structure with an opening, and forms a hook-receiving surface for selective engagement of the hook.

6. The quick-release structure for screen and bracket as described in claim 1, wherein the locking position of the fastener conforms to the Video Electronics Standards Association (VESA) standard distance specification to be applicable to different sizes of the bracket end.

7. The quick-release structure for screen and bracket as described in claim 1, wherein the first pivot end of the pressing member, the second pivot end, and the fastening member together constitute an elbow linkage mechanism.

8. The quick-release structure for screen and bracket as described in claim 7, wherein when the toggle linkage mechanism is in the locked state, the connection between the first pivot end and the second pivot end passes through a dead point.

9. The quick-release structure for screen and bracket as described in claim 1, wherein the operating end of the lever is formed as an arc-shaped handle for user operation.

10. The quick-release structure for screen and bracket as described in claim 1, wherein the hook is in the shape of an inverted hook and is securely engaged with the hook fastener to improve the resistance to detachment.
