[0010]

When the opening / closing member is in the closed state with respect to the mounting body, the first and second hooks on the opposite two sides are rotationally biased outward by the return springs. The fixed shafts of the two opposite sides of the opening / closing member are fitted into the hooks. Therefore, even if the opening / closing member is pulled upward, both fixed shafts are
The closed state is retained by being locked by the first and second hooks.

Next, when the opening / closing member is to be opened, the knob on one side on the opposite two sides of the member is pushed in, and the knob compresses the return spring. The lock releasing pin protruding toward one side of the knob pushes the lock releasing cam of the second hook to push the second
The hook, the first hook, and the rotating shaft are turned inward against the urging force of the return spring, which unlocks the fixed shaft on one side, so that the knob can be opened and closed while pressing the knob. When the member is rotated in the opening direction, the opening / closing member is rotated in the opening direction around the fixed shaft on the other side as a rotation center,
It is opened to a predetermined opening angle.

When the opening / closing member is opened, the lock releasing cam and the lock releasing pin of the second hook are engaged until the fixed shaft and the first and second hooks are completely disengaged. Therefore, when the opening / closing member is opened to a predetermined angle and the push-in operation of the knob is released at the position where the fixed shaft and the first and second hooks are completely separated, the knob is returned to the return spring. It returns to the original position by, but the first and second hooks are
Further, due to the action of the return spring, it rotates beyond the original position (position where the fixed shaft is locked) and then stops.

When the opening / closing member is opened, the slider on the other side, which is connected to the base end of the first hook by a link, is rotated once by rotating the first and second hooks inward. Although it slides to the side, when the first hook rotates outward beyond the original position, it slides to the other side, and the fork part at the tip holds the angular shaft part of the rotary shaft on the other side. Reach As a result, the fixed shaft on the other side and the first and second hooks are fixed, so that even if the knob on the other side is pushed in, the second hook cannot be rotated and the other side is locked. The fixed shaft of will not be unlocked. That is, when the opening / closing member is opened, the opening / closing member functions as a safety device that does not separate from the mounting body even if the knob on the other side is pressed.

When both knobs on the opposite two sides are pushed in at the same time with the opening / closing member closed, the lock release pins of both knobs press the cams of both the second hooks on the opposite two sides. Therefore, both of the second hooks are rotated inwardly, so that the first hooks on both sides, which are integrally connected by the rotation shafts, are similarly rotated inward.

Since each of the first hooks is connected to the slider by a link, both sliders slide to the center of the mounting body, and their base ends abut against each other. In this way, at the position where both sliders abut, the first and second hooks on both sides are in engagement with the fixed shafts on both sides, so the opening / closing member cannot be opened. Therefore, even if the two opposite sides of the opening / closing member are pulled up with both hands, the opening / closing member does not come off, and at this time, even if the knobs on both sides are pushed in accidentally, the opening / closing member also comes off. Does not occur.

Further, when there is a difference in the pushing timing of the knobs on both sides in the closed state of the opening / closing member, the fixed shaft on the side of the knob that is pushed in earlier is unlocked, so that the side of the opening / closing member can be opened.

Next, after opening and closing the opening / closing member, when closing the opening / closing member, the opening / closing member is rotated to be closed, and the fixed shaft is brought into contact with the inclined end faces of the locks provided on the first and second hooks. At the time of abutment, the closing force of the opening / closing member causes the first and second hooks to rotate inwardly against the urging force of the return spring. Both hooks rotate outward due to the urging force of, and the hooks are engaged and locked with the fixed shaft to be in the closed state.
