[Action]

 Secure the upper panel fasteners to the upper part of the panel and the lower panel fasteners to the lower part in place. On the other hand, the skeleton-side fastener is fixed to a predetermined position of a skeleton or a bracket attached to the skeleton (hereinafter collectively referred to as a skeleton). When installing the panel, suspend the panel with the upper panel fastener and the lower panel fastener fixed vertically, place the upper panel fastener above the fixing hook of the upper body side fastener, and the lower panel fastener on the lower body side fastener. Position it above the opening of the movable hook.

Thereafter, the panel is lowered to hook the upper panel fastener on the fixed hook of the upper body-side fastener, and hook the upper panel fastener into the opening of the movable hook of the lower body-side fastener. That is, for one body side fastener, the upper panel fastener of the lower panel is hooked with the fixed hook, and the lower panel fastener of the upper panel is hooked with the movable hook.

At this time, errors such as a skeleton error, a fastener mounting error, and a panel product error are accumulated, so that the axis of the upper panel fastener engaging position and the axis of the lower panel fastener engaging position are perpendicular to each other. If it is not on the line, move the movable hook horizontally through, for example, an adjustment bolt to match the hooked position of the lower panel fastener, and hook the hooked portion of the lower panel fastener in the opening of the movable hook. . If it is necessary to further adjust the panel in the out-of-plane direction after mounting it, move the movable hook horizontally with an adjustment bolt, etc. to make the adjustment.

By providing a stopper above the fixed hook that rotates downward from a predetermined posture but does not rotate upward, when the hooking portion of the upper panel fastener is hooked on the fixed hook, The hooking part rotates the stopper downward and returns to the original position. When the hooking part tries to disengage from the fixed hook, it catches on the stopper. However, since the stopper does not rotate upward, the upper panel fastener does not disengage from the fixed hook. That is, the panel does not come off from the body side fastener. Further, if a cushion pillow made of an elastic material is attached to the bottom of the opening of the movable hook so as to receive the hooking portion of the lower panel fastener, the slight vibration of the panel can be absorbed.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view of the body side fastener, FIG. 2 is a side view, FIG. 3 is a side sectional view showing a state in which the panel is lifted, FIG. 4 is a side sectional view in which the panel is slightly lowered, and FIG. FIG. 6 is a side sectional view showing a state in which the movable hook is completely lowered, FIG. 6 is a side sectional view of an essential portion showing a state before the movable hook is moved, and FIG.

The body side fastener 3 of the fastener of the present invention shown in FIGS. 1 and 2 is provided with a fixed hook 4 below the main body 3 a and is movable above the fixed hook 4 in the horizontal direction. A movable hook 5 is provided. The tip of the adjusting bolt 6 (the left end in the figure) that penetrates the protruding portion 3b of the main body 3a is screwed to the movable hook 5, and the lock nut that is screwed into the adjusting bolt 6 on both sides of the protruding portion 3b. By rotating 6a and 6b, the left and right arrows move. That is, for example, when the left lock nut 6b is loosened and the right lock nut 6a is rotated, the adjustment bolt 6 moves to the right, and the movable hook also moves in the right arrow direction. Similarly, it moves in the left arrow direction.

A stopper 7 that rotates around a pin 3c is provided on the main body 3a above the fixed hook 4. The stopper 7 has a slope on the left end portion 7a side in the figure and is lighter than the right side. Therefore, although the right rotation is attempted, the right rotation is blocked by the contact portion 3d of the main body 3a, and the state shown in the figure is maintained. The space between the tip portion 7a and the upper end of the fixed hook 4 is narrower than the diameter of the retaining shaft 1a of the panel fastener 1 shown in FIG. The movable hook 5 has an opening 5a for receiving the retaining shaft 2a of the lower panel fastener 2 shown in FIG. 3, is narrowed downward, and has a bottom made of an elastic material such as rubber or plastic. The cushion pillow 8 is attached to absorb the slight vibration by receiving the hanging shaft 2a. It should be noted that 3f in FIGS. 1 and 2 is a mounting flange to the body and is provided with a bolt hole 3e.

When mounting the panel 11, as shown in FIG. 3, the upper panel fastener 1 is fixed to the upper part of the lower panel 11 and the lower panel fastener 2 is fixed to the lower part of the upper panel 11 at predetermined positions. At the same time, the body-side fastener 3 is fixed to a predetermined position of the body 14.

Next, the upper and lower panels 11 are vertically hung as shown in FIG. 3, and the retaining shaft 1a of the upper panel fastener 1 is placed above the opening 4a of the fixed hook 4 of the body side fastener 3 and the lower panel. The hook shaft 2a of the fastener 2 is positioned above the opening 5a of the movable hook 5 of the body-side fastener 3. Then, when it is gently lowered a little, as shown in FIG. 4, the latching shaft 1a of the upper panel fastener 1 comes into contact with the sloped portion of the stopper 7 on the tip 7a side, and pushes the tip 7a downward to move the stopper 7 to the left. Rotate.

When the upper and lower panels 11 are completely lowered, the upper panel fastener 1a is locked in the opening 4a of the fixed hook 4 and the locking shaft 2a of the lower panel fastener 2 is movable as shown in FIG. The hooks 5 are hooked in the openings 5a to complete the mounting of the panel 11. At this time, the front end portion 7a of the stopper 7 rotates rightward upward and contacts the contact portion 3c to maintain the state shown in the figure. Therefore, even if the panel 11 rises due to some impact, the latch shaft 1a of the upper panel fastener 1 comes into contact with the tip 7a of the stopper 7 that does not rotate right, and the fixing hook 4 comes out of the opening 4a. Withdrawal is prevented and safety is maintained. Further, since the hook shaft 2a of the lower panel fastener 2 is hooked via the cushion pillow 8, even if there is a shock or a slight vibration, this can be absorbed and the safety can be ensured. The stopper 7 may be omitted if there is no concern that the hanging shaft 1a will come off the fixed hook 4, and the cushion pillow 8 may be omitted if there is no impact or slight vibration.

When mounting the panel 11 as described above, there is an error in the position of the body 14, there is an error in the mounting position of each fastener 1, 2, 3 or there is a manufacturing error in the panel 11. These errors are accumulated, and when the panel 11 is hung vertically, as shown in FIG. 6, the shaft center of the retaining shaft 1a of the upper panel fastener 1 and the retaining shaft 2a of the lower panel fastener 2 are separated. If the axis is not on the vertical line X and there is an error L, operate the lock nuts 6a and 6b of the body side fastener 3 in FIGS. 1 and 2 to move the movable hook 5 in the left arrow direction via the adjustment bolt 6. After that, the panel 11 is lowered and the locking shafts 1a and 2a are locked in the openings 4a and 5a of the fixed hook 4 and the movable hook 5, respectively, as shown in FIG.

If further adjustment of the panel 11 in the out-of-plane direction is required after the panel is mounted, the movable hook 5 is further moved in the horizontal direction by the adjustment bolt 6 and the lock nuts 6a and 6b.
