Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like fastener used for attaching a member or an instrument with a screw to a portion where the inside cannot be accessed.

[0002]

2. Description of the Related Art A conventional means for attaching members or equipment to an object to be attached, such as a wall or a container, which is in a condition where the inside cannot be accessed by a screw, is to insert a plug into a hole formed in the object. Insert the plug, change the posture of the locking member attached to this plug, move the plug in the pull-out direction, and screw the screw into the screw hole of the locking member with the locking member in a state of retaining No. 52-3556) or a thin plate is connected to a position close to the center on one surface side of a rod member provided with a screw hole in the center, and the rod member and the thin plate are inserted into a hole provided so that the rod member passes through an object to be mounted. After that, pull back the thin plate,
It is known that a thin plate is cut off in a state where a rod-shaped member is in contact with an inner surface of an object to be attached, and a screw is screwed into a screw hole of the rod-shaped member (Japanese Patent Publication No. 36-18855).

[0003]

By the way, the above-mentioned conventional fastener means has a structure in which the fastener is inserted and the screw is screwed in by using one hole provided in the attachment. Therefore, when the screws are tightened, if an excessive rotation torque is applied, the fastener means rotates together, and there is a problem that the fastener cannot be fastened.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a plate-shaped fastener which does not cause co-rotation at the time of fastening a screw and which can achieve a reliable fastening with excellent pull-out resistance.

[0005]

In order to solve the above-mentioned problems, the invention of claim 1 comprises a plate-like body and a bendable thin plate projecting from one side of the plate-like body at an angle. A screw hole for screwing a screw into the plate-like body and a screw insertion hole in a thin plate are employed.

According to a second aspect of the present invention, in the first aspect of the present invention, the thin plate includes an attachment portion to the plate-like body and an extension portion which is bent continuously from the attachment portion and provided with a screw insertion hole. It is formed, the mounting part is overlapped and fixed on one side of the plate-like body,
This adopts a configuration in which the rear end side of the plate-like body projects rearward from the mounting portion.

Here, the mounting object is provided with a predetermined distance between a plate-like body, a square hole through which a thin plate overlapping the plate-like body can be inserted, and a round hole through which a screw is inserted. Pulling the sheet back along the inner surface of the mounting object and bending the thin plate to the outer surface of the mounting object, the screw hole and screw insertion hole match the round hole, and the screw hole of the plate Screw can be fastened.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in the figure, a plate-like fastener 1 is formed by using a horizontally long plate-like body 2 having an appropriate plate thickness and a bendable thin metal plate so as to bend in the middle. The thin plate 3 is formed by combining a thin plate 3 fixed to one surface side of the plate 2, and the thin plate 3 is formed by bending a strip having a width substantially equal to that of the plate 2 in the middle thereof, and attaching an attaching portion 4 to the plate 2. It is formed by an extension portion 5 that is bent continuously from the rear end of the attachment portion 4.

In the case of FIG. 1, the mounting portion 4 is slightly shorter than the length of the plate-like body 2 and is overlapped on one side of the plate-like body 2 with its leading end coinciding with the leading end of the plate-like body 2. At the same time, the overlapping portion is fixed by welding or bonding, and the extension portion 5 projects from the plate-shaped body 2 to the upper rear portion at an angle.

Therefore, the rear end side of the plate-like body 2 is
The protrusion 2a extends rearward from the rear end.

A screw hole 6 is provided in a penetrating manner at a position where the plate-like body 2 and the mounting portion 4 overlap with each other and slightly toward the distal end, and an elongated screw insertion hole 7 is provided in the extension 5. ing.

The fastener according to the present invention is configured as described above. To attach the member or the tool 12 to the object 11 to which the inside is inaccessible, as shown in FIG.
A square hole 13 having a size enough to insert the overlapping portion of the plate body 2 and the thin plate 3 into the mounting object 11 and a screw insertion hole 14 at a position provided at a predetermined distance from the square hole 13 by means such as pressing. By drilling.

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.

FIG. 2
As shown in (A), the overlapping portion of the plate 2 and the thin plate 3 is inserted into the square hole 13. At this time, the extension part 5 of the thin plate 3 passes through the square hole 13 in a straight line with the mounting part 4. Plate 2
When the entire length of the thin plate 3 passes through the square hole 13, the thin plate 3 is bent at the original angle with respect to the extension 5 by the restoring elasticity of the thin plate 3, and the plate 3 2
When the extension portion 5 is pulled back in this state, the rear end protruding portion 2a of the plate-shaped body 2 comes into contact with the inner surface of the attachment 11 as shown in FIG. ,
As shown in FIG. 3 (A), 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, and the screw hole 6 coincides with the screw insertion hole 14.

Next, the extension 5 of the thin plate 3 is
3B, the object 11 is sandwiched between the bent portion of the extension portion 5 and the plate 2 from inside and outside as shown in FIG. The screw insertion hole 7 coincides with the screw insertion hole 14.

In this state, a member or a tool 12 is superimposed on a portion of the extension portion 5 bent at the outer surface of the mounting object 11, and a screw 15 inserted into the tool 12 is screwed into the screw hole 6 of the plate-like body 2 serving as a seat plate. By screwing in with a tool toward, the member or the tool 12 can be fastened to the outer surface of the attachment 11.

At the time of fastening by screwing the screw 15, the plate-like fastener 1 has the extension 5 penetrating through the square hole 13 to be a complete detent, and this penetrating portion is separated from the tightening position of the screw 15. Therefore, even if a rotational torque is applied by tightening the screw 15, the plate-shaped body 2 does not co-rotate at all, and a strong fastening force can be obtained.

FIG. 5 shows another example of the plate-shaped fastener 1.
The plate-like body 2 is bent in the middle so as to form a step at the rear part on the front surface side, and the attachment part 4 of the thin plate 3 is shortened and fixed to the plate-like body 2 at the position of the step, and the plate-like body 2 and the attachment part 4 Are flush with each other.

Although not shown, a step portion may be provided by cutting a rear portion of the plate-like body 2 on the front surface side, and an attachment portion may be fixed to the step portion.

[0021]

As described above, according to the present invention, a bendable thin plate projecting at an angle from one side is fixed to a plate-like body, and a screw hole and a screw insertion hole are provided in the thin plate. Therefore, when a member or an instrument is screwed to a part that cannot be accessed inside, there is no occurrence of co-rotation in the plate-like body provided with the screw hole, and there is no possibility that a fastening failure occurs.

Further, the member to be mounted is sandwiched between the inner and outer surfaces of the plate and the thin plate, and the members and instruments are fastened with screws screwed into the screw holes of the plate. The pull-out resistance of the screw is greatly improved.
