DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
As shown in the figure, the plate-like fastener 1 is formed so as to be bent in the middle using a horizontally long plate-like body 2 having an appropriate plate thickness and one foldable metal thin plate. The thin plate 3 is formed by a combination of a thin plate 3 fixed to one surface side, and the thin plate 3 bends a strip having a width substantially equal to that of the plate-like body 2 in the middle, and an attachment portion 4 to the plate-like body 2 and the attachment portion 4. And an extension portion 5 bent continuously from the rear end.
[0010]
In the case of FIG. 1, the attachment portion 4 is slightly shorter than the length of the plate-like body 2 and is superposed on one surface side of the plate-like body 2 in a state where its tip is aligned with the tip of the plate-like body 2. The overlapping portion is fixed by welding or adhesion, and the extension portion 5 protrudes from the plate-like body 2 upward at the rear with an angle.
[0011]
Therefore, the rear end side of the plate-like body 2 is a protruding portion 2 a that extends rearward from the rear end of the attachment portion 4.
[0012]
A screw hole 6 is provided in a penetrating manner at a position slightly closer to the distal end side in a portion where the plate-like body 2 and the attachment portion 4 overlap, and an elongated screw insertion hole 7 is provided in the extension portion 5.
[0013]
The fastener according to the present invention is configured as described above, and in order to attach a member or instrument 12 to an attachment 11 that is not accessible inside, as shown in FIG. A square hole 13 sized to be inserted through the overlapping portion of the body 2 and the thin plate 3 and a screw insertion hole 14 at a predetermined distance from the square hole 13 are formed by means such as a press.
[0014]
The distance between the square hole 13 and the insertion hole 14 corresponds to the distance from the bent portion of the thin plate 3 to the screw hole 6.
[0015]
In order to attach the member or the instrument 12, as shown in FIG. 2A, the overlapping portion of the plate-like body 2 and the thin plate 3 is inserted into the square hole 13. At this time, the extension portion 5 of the thin plate 3 is linear with the attachment portion 4 and passes through the square hole 13. When the entire length of the plate-like body 2 passes through the square hole 13, due to the restoring elasticity of the thin plate 3, the attachment portion 4 bends to the original angle with respect to the extension portion 5, and the thin plate 3 is bent with respect to the inner surface of the attachment 11. The plate-like body 2 becomes inclined, and when the extension portion 5 is pulled back in this state, the rear end protruding portion 2a of the plate-like body 2 comes into contact with the inner surface of the attachment 11 as shown in FIG. When a pulling force is applied, the plate-like body 2 overlaps the inner surface of the attachment 11 via the attachment portion 4 with the corresponding contact portion as a fulcrum as shown in FIG. 3A, and the screw hole 6 matches the screw insertion hole 14. To do.
[0016]
Next, when the extension portion 5 of the thin plate 3 is bent along the outer surface of the attachment object 11, the attachment object 11 is formed by the bent portion of the extension portion 5 and the plate-like body 2 as shown in FIG. The screw insertion hole 7 provided in the extension portion 5 coincides with the screw insertion hole 14.
[0017]
In this state, a member or an instrument 12 is stacked on the portion of the extension portion 5 bent at the outer surface of the attachment object 11, and the screw 15 inserted through the instrument 12 is directed toward the screw hole 6 of the plate-like body 2 serving as a seat plate. By screwing with a tool, the member or the instrument 12 can be fastened to the outer surface of the attachment 11.
[0018]
At the time of fastening by screwing in the screw 15, the plate-like fastener 1 has the extension portion 5 penetrating the square hole 13 to be completely non-rotating, and this penetrating portion is separated from the fastening position of the screw 15. Even if rotational torque is applied by tightening the screw 15, there is no co-rotation in the plate-like body 2, and a strong fastening force can be obtained.
[0019]
FIG. 5 shows another example of the plate-like fastener 1. The plate-like body 2 is bent in the middle so that a stepped portion is formed on the rear side of the surface side, and the attachment portion 4 of the thin plate 3 is shortened to form a plate-like shape at the position of the stepped portion. It adheres to the body 2 and the surfaces of the plate-like body 2 and the mounting portion 4 are flush.
[0020]
Although not shown in the figure, a stepped portion may be provided by cutting the front side of the plate-like body 2 and the attaching portion may be fixed to the stepped portion.
[0021]
【The invention's effect】
As described above, according to the present invention, a foldable thin plate that protrudes at an angle from one side is fixed to a plate-like body, and a screw hole is formed in the plate-like body and a screw insertion hole is formed in the thin plate to form a plate-like fastener. Then, a square hole having a size for inserting the overlapping portion between the plate-like body and the attachment portion and a screw insertion hole at a distance from the square hole are inserted into the attachment object to which the plate-like fastener is attached. The distance between the square hole and the screw insertion hole is set to match the distance from the bent portion of the thin plate of the plate-shaped fastener and the bent portion of the extension portion to the screw hole. If the thin plate is pulled back in a state where the object is inserted and positioned on the back side of the attached object, the plate-like body contacts the back side of the object to be attached, and the screw hole and the screw insertion hole are aligned, Put parts and instruments on the inside of your hands Scan it is possible to stop, in the case of the screwing, since the thin plate extend through the square holes, no generation of co-rotation to the plate-like member having a screw hole, does not fall into engagement impossible situation .
