JPH03283600A - Double locking mechanism for open/close panel - Google Patents

Abstract

PURPOSE:To need two-step operation when a panel is opened and to perform by one operation when it is closed by providing a locking bracket, and moving a stopper through the bracket when it is opened. CONSTITUTION:Only when a button 1 for opening a door is merely pressed, the end of a locking bracket 2 is brought into contact with the lower end of a releasing bracket 6, the bracket 6 cannot be rotated, and the engagement of the cutout of a stopper 3 with a releasing pin 7 is not disengaged. When a locking button 5 is pressed, the lower end of the bracket 2 is separated from the bracket 6. Then, when the button 1 is further pressed, the bracket 6 is rotated to press down the stopper 3 by the end of opposite side to open a panel 4. When the panel 4 is closed, if the panel 4 is pressed, the end of the stopper 3 held by a spring at a stable position is pressed by the pin 7, only the stopper 3 is moved irrespective of the bracket 2, the panel 4 is closed, and locked.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a double locking mechanism for an opening/closing panel, and in particular to an opening/closing mechanism in which the lock is released by two operations in order to prevent the panel from being easily opened due to an erroneous operation. Concerning the double locking mechanism of the panel.

[Conventional technology]

FIG. 3 shows an example of a double locking mechanism conventionally used in electronic devices and the like to prevent openable and closable panels from being easily opened due to erroneous operation. In Figure 3,
The stopper 11, which engages with a lock pin of the panel 13 to fix the panel 13, is normally locked by a lock shaft 10, so that it does not move even if the button 12 for opening the door is pressed. When opening the panel 13, first operate the lock lever 9 to displace the lock shaft 1° in the direction of arrow E, release the lock, and then press the button 12.
Two operations are required: pressing , moving the stopper 11, and releasing the engagement with the lock pin. This will prevent the panel from opening due to erroneous operation, but the lock lever must be used when closing the panel 13 in the same way as when opening it.
It was necessary to perform two operations: operating the panel 9 and then engaging the panel 13.

[Problem to be solved by the invention]

The conventional double locking mechanism of the opening/closing panel described above requires two operations when opening the panel and prevents it from opening easily due to an incorrect operation, but it also requires two operations when closing the panel. The disadvantage is that it requires extra effort.

An object of the present invention is to provide a double locking mechanism for an opening/closing panel that requires two movements when opening, but can be operated in one movement when closing.

[Means to solve the problem]

The double locking mechanism for the openable panel of the present invention has a notch that engages with a lock pin attached to the panel that can be opened and closed to fix the panel when it is in a stable position, and when the panel is closed. A stopper that is easily displaced from the stable position by an external force applied by the lock pin, and a stopper that is displaced by operation of a door opening button to displace the stopper from the stable position and release the engagement between the notch and the lock pin. and a release bracket that normally prohibits displacement of the lock bracket and enables 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.

The locking mechanism 8 in FIG. 1 requires two operations: pushing the lock button 5 and pressing the button l when opening the panel 4 in the direction of the arrow; however, when closing the panel 4
It is configured so that all you have to do is press the button.

FIGS. 2(a), 2(b) and 2(C) are perspective views of the locking mechanism section 8 of FIG. 1 seen from directions A, B and C, respectively. The locking mechanism shown in FIG. 2 includes a stopper 3 that engages with a lock pin 7 attached to a panel 4, a release bracket 6 that rotates the stopper 3 by operating a button l,
At all times, the operation of the release bracket 6 is prohibited and the lock button 5 is
The lock bracket 2 is provided with a lock bracket 2 that can be operated by the operation of the lock bracket 2.

If the door opening button 1 is simply pressed, the tip of the lock bracket 2 will hit the lower end of the release bracket 6, and the release bracket 6 will not be able to rotate and the engagement between the notch of the stopper 3 and the lock pin 7 will not be released. When the lock button 5 is pressed, the lower end of the lock bracket 2 separates from the release bracket 6 as shown by the dashed line in FIG. 2(b). Then, when the button 1 is further pressed, the release bracket 6 rotates and the opposite end pushes down the stopper 3 and the panel 4 opens.

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

In the above-described embodiment, the stopper 3 is held in the stable position shown by the spring, but the stable position may be maintained by gravity instead of the spring. Further, in the embodiment, the lock bracket 2 is configured to rotate by operating the button 1, and the release bracket 6 is configured to perform a linear displacement, but the same effect can be achieved by other operations and displacements. It is possible to

〔Effect of the invention〕

As explained in detail above, the present invention has a lock bracket and is configured to move the stopper via the lock bracket when opening the panel. Therefore, when opening the panel, two operations are required. Closing the panel requires only one operation, which has the effect of preventing the panel from opening easily due to an erroneous operation and eliminating unnecessary operations.
