Abstract

PURPOSE:To enable a display panel to be prevented from loosening or dropping due to an external force, make panel setting hardly neglected, eliminate a failure to tighten a setscrew, and a panel dislocation due to failure to tighten the setscrew, and increase the external appearance of the panel. CONSTITUTION:A display panel mounting mechanism comprises a hook section 11 having a claw at the lower part of a display panel 1, a movable plate 13 vertical to the face of the panel 1 at the upper end thereof and having a flat projection, and a lever 12 rotatably advancing and retreating to and from a gap at the movable plate 13. In this case, the hook section 11 is inserted in a hole at the lower part of an enclosure and the panel 1 is horizontally pushed with the hole used as a support point. The mounting mechanism is thereby engaged with the hole of another enclosure 2 and the panel 1 is temporarily supported vertically. Then, the lever 12 is reversed, thereby preventing the movable plate 13 from warping inside.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display panel mounting mechanism for a display board device.

0002

[Prior Art] A conventional display panel fixing method includes hooks at the bottom and top, the top hook is longer than the bottom, and the hook is engaged with a hole in the housing. It was fixed using screws.

0003

[Problems to be Solved by the Invention] The conventional panel fixing method described above has a problem in that the fixing screws are exposed to the outside, detracting from the aesthetic appearance. In addition, it is difficult to install and remove panels in unsafe locations, such as high up on a wall, and there is a risk of damaging the screw heads with a screwdriver, making it difficult to remove the panel and affecting maintenance time. There was a problem that there was.

[0004] Another problem is that some screws are forgotten to be tightened, and in this state, an external force is applied to the panel surface from below, causing the lower hook to come off and the entire panel to come off.

[0005] The operation for removing the panel is performed by moving the panel up and down, but because the panel is flat, a hook cannot be formed. Since I can't operate the panel, I insert a flat head screwdriver into the gap between the panels and pull the panel out. As described above, there are also problems in the method of removing the panel by sliding it in the vertical direction.

An object of the present invention is to provide a display panel mounting mechanism that solves these problems.

[0007]

[Means for Solving the Problems] The display panel mounting mechanism of the present invention has a conventional hook formed at the bottom of the display panel, and at least one set of parallel flat plate-shaped hooks at the top of the panel. A pair of protruding plates provided with hooks are formed perpendicularly to the panel surface, and a rotating lever having a positioning/retracting function is disposed between the protruding plates.

[0008] Furthermore, the present invention has a square hole on the casing side into which the hook part engages, and the hook part of the display panel 3 is engaged with this lower square hole, and the upper part is mounted using this as a fulcrum. This consists of means for temporarily supporting the panel by pushing the mechanism from the front and engaging the upper square hole.

[0009]The present invention is achieved by reversing the rotating lever compared to when the movable plate is temporarily supported, thereby preventing the movable plate from deflecting inward.

To remove the display panel 1, when the lever 12 is rotated in the P direction shown in FIG. Put your finger on the lever storage part 16 in Figure 3.
When the movable plate is pulled in the F' direction, the slope of the hook portion 13B of the movable plate is deflected along the end surface of the hook hole 22, and is removed from the hook hole 22.

Next, when the upper part of the display panel is supported and pulled toward the user, the end of the lower end hook part 11B that contacts the casing surface contacts point K and rotates open. Furthermore, the display panel can be removed from the housing 2 by lifting it.

When the display panel 1' is mounted, the display panel 1' is formed so that the lever 12 can be rotated to a position (point E) on which the lever 12 is placed. In addition, in order to prevent the tip of the movable plate 13 from being deflected due to a load outside the display panel attachment/detachment operation when the display panel 1 is removed, the mounting mechanism portion 1A is fixed by bringing the inner protrusions 13D and 13D' into contact with each other at point S. It has a structure that prevents damage.

[0021]

As described above, according to the display panel mounting mechanism of the present invention, the display panel is mounted by first inserting the protrusion of the display panel into the hooking hole at the bottom of the housing. At this stage, the display panel itself is supported, and then by pushing the top of the display panel in the horizontal direction, the mounting mechanism engages with the housing hole, and the display panel is temporarily supported vertically.

In this state, the display panel will not come off unless it is pulled forward, so there is no fear of it coming off or falling due to external force. Furthermore, by setting the lever, the movable plate of the mounting mechanism is prevented from deflecting, so it will not come off due to external force.
It can prevent falling. Additionally, if you forget to set the lever, you can visually confirm it, which helps prevent you from forgetting to set the lever. Therefore, maintainability is improved since no screwdriver is required, and displacement of the display panel due to forgetting to tighten screws can be prevented. In addition, since no screws are used, the aesthetic appearance is not impaired, and the external design can be further enhanced. By connecting the housing and the display panel with a string at the upper end using a well-known attachment method, it is possible to hold the display panel open at a certain angle using the lower part of the display panel as a fulcrum.
