DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for firmly fixing a bolt from the front side of a wall when a hook or a bracket is mounted on a wall surface.

[0002]

2. Description of the Related Art When a hook or a bracket is mounted on a wall surface, if the space behind the wall is a space, even if nails, screws, or the like are struck or inserted, the supporting force is weak, and it is easy to loosen or fall off. Many. It is perfect if the nuts are tightened from behind the wall using small bolts, but it is inconvenient if the back space is not accessible. There is an anchor type bolt that opens like an umbrella on the back side of the plate when tightening the bolt, but the pinching strength against the plate is not enough, so if the load is large or there is repeated vibration, rattling will occur. In many cases, the wall itself is damaged and the fixed state cannot be maintained.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and allows a bolt to be easily and firmly fixed from the back side of a wall plate when a hook or a bracket is mounted on a wall surface. The equipment is provided.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a rotary blade 2 having a length 1 / half the length L of the rotary blade 2.
Pivot parts 5 and 5 are provided on both sides of the offset part exceeding 2L,
In addition, a female screw hole 3 having a diameter is formed through the one-sided portion on a line connecting the pivot portions 5 and 5. And the pivot 5,
5, a tip 4a of a handle rod 4, 4 made of a soft plastic material is pivotally supported, and the longitudinal portion 2a of the rotary vane plate 2 is weight-dropped with the pivots 5, 5 as a rotation base point. . Further, the rotary wing plate 2 is made of metal.
Further, the handle rod 4 is U-shaped.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described with reference to FIG. Offset portion (the longitudinal portion 2a of the rotating blade is 2 / 3L, the short portion 2b of the rotating blade is
(1 / 3L) are provided with pivots 5a, 5a on both sides 2c.
A female screw hole 3 sized to allow a bolt B having a diameter to be screwed on a line A connecting the pivots 5a, 5a is formed in the one-sided portion. A pivot hole 6 is provided at the distal end 4a of the U-shaped handle rod 4 formed of a bendable thick line, so that the pivot 5
a, 5a. And, the longitudinal portions 2a of the rotary vane plate 2 are configured so as to hang down in weight from the pivots 5a, 5a as a rotation base point.

When the handle rod 4 is U-shaped, it can be easily inserted with one hand, but it is also possible to use two handle rods 4 and insert it into the wall plate with both hands. In this case, the rotating blade reversing stopper 7 is bridged at a distance of 1/2 L from the pivots 5a, 5a in the middle of the handlebars 4, 4 and is welded and connected in an H-shape. And the longitudinal portion 2a can always be inserted first. Further, in order to make it easy to sandwich the rotary blade 2 horizontally with the handle rod 4 at the time of insertion, a projection of the rotation stopper 8 is provided on the side surface 2c of the rotary blade 2 or a groove ( (Not shown) can also be provided.

In the above embodiment, the rotary blade 2
Has shown the aspect in which the longitudinal portion 2a of the
Conversely, the longitudinal portion 2a of the rotary wing plate 2 may be located on the front side. In this case, the weight of the rotary wing plate 2 sags from the front side. The one without the rotation stopper 8 is the handle rod 4,
4 remove the middle from both side surfaces 2c of the rotary vane plate 2 and
In the case of FIG. 1, the intermediate portion of the rotary blade 2 is narrowed by pushing inward, and in the case of FIG. In the case where the longitudinal portion 2a of the rotary vane plate 2 is located on the front side, the horizontal state can be maintained by placing the longitudinal portion 2a of the rotary vane plate 2 on the handlebars 4 and 4.

The method of attaching the handle rod 4 to the side surface 2c of the rotating blade plate counterpart 2 is as shown in FIG.
5a is provided, and a pivot hole 6 provided at the distal ends 4a, 4a of the handle rod 4 is mounted thereon. However, separately from this, the distal ends 4a, 4a of the handle rod 4 are wound around the pivots 5a, 5a. It may be of the type. FIG. 1 shows the embodiment using the pivots 5a, 5a as described above. However, separately from the embodiment, the pivots 5 are replaced with the pivots 5a, 5a, and pivot holes are provided at the positions of the pivots 5a, 5a. And the tip 4 of the handlebar 4
a, 4a may be bent inward, and the bent portion may be inserted into the shaft support hole to enable the rotary blade 2 to rotate.

As for the rotary blade plate 2, besides the above-mentioned metal, plastic, wooden and the like can be used. The material of the handle rod 4 can be temporarily fixed to the wall plate when it is bent, and may be lead, which is one of soft metals, so that it can be easily cut at the end. However, various alloys of a flexible plastic material may be used. Are suitable.

[0010]

[Method of use] The method of use of the present invention will be described in an effective manner.
As shown in FIG. 2, a notch D1 through which the rotary wing plate 2 can pass horizontally on the wall plate is provided on both sides, and a bolt through hole D is provided at the center thereof.
The insertion hole D in which 1 is formed is opened. As shown in FIG. 3, the side surfaces 2 of the rotary vane plate 2
The rotary wing plate 2 is fixed in a horizontal state by pressing so as to sandwich the c, and is inserted into the insertion hole D in that state. At this time, the rotary blade 2 can be easily brought into a horizontal state by providing a rotary blade reversing stopper 7 on the handle rod 4 or a rotary stopper 8 on the side surface 2c of the rotary blade 2.

When the entire portion of the rotary wing plate 2 comes off the back side of the wall plate, the opening of the handle rod 4 is released. As a result, as shown in FIG.
Since it is heavier than b, it hangs down naturally, and the rotary blade 2 rises. Then, as shown in FIG. 5, the handle rod 4 is pulled to the front side, and the rotary wing plate 2 is drawn to the back surface of the wall plate. Then, as shown in FIG. 6, the handle rod 4 protruding from the surface of the wall plate is bent to temporarily fix the rotary wing plate 2.

Next, as shown in FIG. 8, the bolt B is passed through a stop hole of the hanging bracket T, and the surface of the wall plate and the bolt B are sandwiched by the hanging bracket T. The bolt B is screwed into the screw hole 3. Then, as shown in FIG. 9, the handle rod 4 protruding from the wall plate is cut, and the mounting operation is completed. In addition, the pivot holes 6, 6 at the tips 4a, 4a of the handle rod 4,
If the shaft 6 is detached sideways from the pivots 5a, 5a, it is easy to remove the handle rod 4 at the last stage.

[0013]

According to the present invention, as described above, the rotary blade 2 is inserted into the insertion hole D provided in the wall plate.
Is lifted by the weight drop of the longitudinal portion 2a, the rotary wing plate 2 is pulled by the handle rod 4, the plate surface of the rotary wing plate 2 is brought into close contact with the rear surface of the wall plate, and the bolt B is inserted into the female screw hole 3. By screwing and tightening the wall plate from both the front and back, the wall plate itself was reinforced, and it became possible to firmly fix hooks and brackets to the wall surface. For this reason, even heavy objects can be securely mounted on the wall.
