[0003]

[Problems to be solved by the device]

 Attaching the panel to the body requires a lot of work and time, including positioning and adjustment such as centering, which is labor-intensive and dangerous. An object of the present invention is to provide a fastener capable of mounting a panel to a body in a safe, reliable and quick manner in a short time.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to achieve the above-mentioned object, and its constitution is as follows: an upper panel fastener fixed to the upper part of the panel, a lower panel fastener fixed to the lower part of the panel, and a lower part of the main body. A fixing hook for hooking a horizontal hooking portion of the upper panel fastener is provided, and a horizontal pin provided on the main body is fitted in the long groove above the hook to move and rotate the hook vertically. It has a stopper portion that is movable and that can be engaged with and disengaged from the vicinity of the upper portion of the main body, and further has a downward hook portion that engages with the horizontal locking portion of the lower panel fastener. It is characterized by comprising a body side fastener provided with a movable hook.

[0005]

[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 body side fastener is fixed to a predetermined position on the body. When installing the panel, first hook the hooking part of the upper panel fastener on the fixing hook of the body side fastener to receive the weight of the panel, turn the panel in the direction of the body with the hooking part as the axis, and pull up in advance. By rotating the stopper, the stopper of the lower panel fastener is abutted against the lower surface of the movable hook of the lower body fastener that has been hooked around the upper part of the body of the body fastener.

When the locking portion of the lower panel fastener hits the movable hook, the movable hook rotates in the opposite direction, the stopper portion is disengaged from the body side fastener main body, and the movable hook falls along the long groove to lower the lower panel. The locking part of the fastener is engaged with the downward hook part of the movable hook, and the panel is fixed to the body to complete the installation. That is, the panel can be mounted safely, securely and quickly with one touch.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view of a body side fastener showing an embodiment of the present invention, FIG. 2 is a side sectional view showing a state before panel fixing, FIG. 3 is a side view showing a state after fixing, and FIG. 4 is another embodiment. FIG. 5 is a side sectional view before fixing showing an example, FIG. 5 is a side sectional view after fixing, and FIG. 6 is a perspective view of a body side fastener showing another embodiment.

Embodiment 1 The body side fastener 3 of the fastener of the present invention shown in FIG. 1 is provided with two fixing hooks 4 at appropriate intervals below the main body 3a, and the fixing hooks 4 are It is of a double type in which a movable hook 5 is provided above. Then, the fixing hook 4 has a horizontal hooking pin of an upper panel fastener (shown by a chain double-dashed line) fixed near the left and right sides of the upper ends of the lower right and left panels (not shown). The lower panel fastener 2 (indicated by a chain double-dashed line) is fastened to the movable hook 5 on the left and right sides of the lower ends of the right and left panels (not shown) that are one step above the movable hook 5. The horizontal locking pin 2a is locked in the recess 5d of the hook 5c facing downward to fix the panel 11.

More specifically, as shown in FIG. 2, a fixing hook 4 for hooking a horizontal hooking pin 1a of an upper panel fastener 1 fixed to an upper portion of a lower panel 11 is attached to a bracket or It is provided below the main body 3a of the body-side fastener 3 attached to the body 14, and the horizontal pin 3b provided on the main body 3a is fitted into the elongated hole 5a on the main body 3a above the fixing hook 4. There is provided a movable hook 5 which can be vertically moved and horizontally rotated in the drawing. The movable hook 5 is provided with a stopper portion 5b which can be locked and disengaged from the upper end portion of the main body 3a, and a downward hook portion 5c having a groove 5d.

In mounting the panel 11, as shown in FIG. 2, the movable hook 5 is pulled up and rotated rightward so that the stopper portion 5b is hooked on the upper end of the main body 3a. Next, the hooking pin 1a of the upper panel fastener 1 fixed to the upper portion of the panel 11 (FIG. 2 shows the state of being fixed to the upper portion of the lower panel 11) is hooked on the fixing hook 4 and the panel 11 of the panel 11 is fixed. After receiving its own weight, the panel 11 is pivoted in the direction of the arrow (a) (the direction of the bracket or the frame 14) around the retaining pin 1a as an axis, and is fixed to the lower part of the panel 11 (FIG. Of the lower panel fastener 2) The horizontal locking pin 2a of the lower panel fastener 2 is abutted against the front surface 5e of the movable hook 5.

When the locking pin 2a hits the front surface portion 5e, the movable hook 5 is rotated counterclockwise, the stopper portion 5b is disengaged from the upper end of the main body 3a, and the stopper portion 5b falls along the long hole 5a due to its own weight, and the downward hook portion. The locking pin 2a is fitted and locked in the groove 5d of the groove 5c, and the state shown in FIG. That is, the panel 11 can be attached safely, reliably and quickly with one touch.

Embodiment 2 In this embodiment, as shown in FIGS. 4 and 5, a long groove 5d is formed by combining the long hole 5a of the movable hook 5 and the groove 5d of the hook portion 5c. The pin 3b is fitted in the groove 5d so that the movable hook 5 can move up and down and turn left and right. Further, a cutout groove 5f following the stopper portion 5b is formed on the main body 3a side, and the horizontal pin 3c of the main body 3a is fitted therein to regulate the vertical movement. The other structure is similar to that of the first embodiment.

The operation is almost the same as in the case of the first embodiment, but when the locking pin 2a of the lower panel fastener 2 hits the front surface portion 5e of the movable hook 5 at the time of mounting and the movable hook 5 falls, As shown in FIG. 5, the movable hook 5 is held by the pin 3b in the groove 5d, and the locking pin 2a is fitted and locked in the groove 5d. That is, like the first embodiment, this embodiment (shown in FIGS. 4 and 5) can also attach the panel 11 safely, reliably and quickly with one touch.

[0014]

[Effect of the device]

 As described above, according to the present invention, the panel can be attached to the body safely and securely and quickly in a short time by one-touch, so that the construction period can be shortened and it has an effect of contributing to safety management. . In the above-described embodiment, the double-type body-side fastener 3 as shown in FIG. 1 has been described, but the present invention is not limited to the double-type fastener 3, and the hook 4 may be provided below the main body 3a as shown in FIG. It is needless to say that a single-type frame-side fastener 3 having one movable hook 5 provided above the above-mentioned one has the same operation and effect, and the utility value of this single type is also great.
