Description

Description: TECHNICAL FIELD The present invention relates to a double lock mechanism for an opening / closing panel, and in particular, an opening / closing method for releasing a lock by a two-action operation in order to prevent the panel from easily opening due to an erroneous operation. Regarding a double lock mechanism of a panel.

[Conventional technology]

FIG. 3 shows an example of a double lock mechanism conventionally used to prevent an openable / closable panel from being easily opened by an erroneous operation in an electronic device or the like. In FIG. 3, the stopper 11 that engages with the lock pin of the panel 13 to fix the panel 13 is normally locked by the lock shaft 10 so that it does not move even if the button 12 for opening the door is pushed. ing. To open the panel 13, first operate the lock lever 9 to displace the lock shaft 10 in the direction of arrow E, release the lock, and then push the button 12 to move the stopper 11 to release the engagement with the lock pin. Behavioral manipulation is required. This can prevent the panel from opening due to an erroneous operation, but when closing the panel 13, it is necessary to operate the lock lever 9 and then close the panel 13 in the same manner as when opening the panel 13.

[Problems to be Solved by the Invention]

The conventional double lock mechanism for the open / close panel described above requires a double-action operation when the panel is opened, so that it cannot be easily opened due to an erroneous operation, but it also requires a double-action operation when the panel is closed. Therefore, there is a drawback that it takes extra time.

It is an object of the present invention to provide a double lock mechanism for an opening / closing panel which requires two movements of operation when being opened, but can be operated with one movement when being closed.

[Means for solving the problem]

The double lock mechanism of the opening / closing panel of the present invention has a notch for fixing the panel by engaging with a lock pin attached to the panel that can be opened / closed when in the stable position, and has the notch for closing the panel. A stopper that is easily displaced from the stable position by an external force given by the lock pin and a stopper that is displaced by operating a button for opening the door to displace the stopper from the stable position to release the engagement between the notch and the lock pin. It comprises a lock bracket and a release bracket which prohibits the displacement of the lock bracket at all times and allows the displacement by operating a lock button.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of an embodiment of the present invention. When the panel 4 is opened in the direction of the arrow D, the lock mechanism section 8 shown in FIG.
Although it is necessary to perform a two-motion operation of pressing, the panel 4 is configured to be pressed in only one motion when closing.

2 (a), (b) and (c) are perspective views of the lock mechanism portion 8 of FIG. 1 seen from the A, B and C directions, respectively. The lock mechanism shown in FIG. 2 includes a stopper 3 that engages with a lock pin 7 attached to a panel 4, and a release bracket 6 that rotates the stopper 3 by operating a button 1.
And a lock bracket 2 that prohibits the operation of the release bracket 6 at all times and enables the operation by operating the lock button 5.
It has and.

By simply pressing the button 1 for opening the door, the tip of the lock bracket 2 contacts the lower end of the release bracket 6, the release bracket 6 cannot rotate, and the engagement with the lock pin 7 in the notch of the stopper 3 is not released. When the lock button 5 is pressed, the lower end of the lock bracket 2 is separated from the release bracket 6 as shown by the alternate long and short dash line in FIG. Then, when the button 1 is further pressed, the release bracket 6 rotates and the tip on the opposite side pushes down the stopper 3 to open the panel 4.

When the panel 4 is closed when the panel 4 is closed, the lock pin 7 pushes down the tip of the stopper 3 held by the spring at the stable position shown in the figure, and only the stopper 3 moves regardless of the lock bracket 2. 4 is closed and locked.

In the above-described embodiment, the stopper 3 is described as being in the stable position shown by the spring, but it is also possible to keep the stable position by gravity instead of by the spring. Further, in the embodiment, the lock bracket 2 is rotated by the operation of the button 1 and the release bracket 6 is linearly displaced. However, the same operation is performed by operations and displacements other than the above. It is possible.

〔The invention's effect〕

As described above in detail, since the present invention has the lock bracket and is configured to move the stopper via the lock bracket when opening the panel, it requires a two-action operation when opening the panel. When it is closed, only one operation is required, and it is possible to prevent the panel from being opened easily due to an erroneous operation and to save an extra operation.
