Description

[0001]
[Technology to which the invention belongs]
The present invention relates to an auxiliary tool for attaching to a gypsum board, a plywood board, etc., and more particularly to an auxiliary tool for preventing the attachment of a board anchor that expands in the radial direction with respect to the axis of a leg during operation.
[0002]
[Prior art]
Japanese Examined Patent Publication No. Sho 56-16292 is an example of an anchor for a board to be attached to a plaster board and a plywood board disclosed in the past. The action of the board anchor enables the leg part to be firmly fixed to the gypsum board and the plywood board by expanding in the radial direction with respect to the axis of the leg part. Hereinafter, gypsum board and plywood are called materials.
[0003]
In general, as a proposed method for fixing the board anchor to the material, it is desirable to provide a hole in the material in advance using a drilling tool. It is necessary to insert a board anchor into the perforated hole and then perform a leg opening operation using various auxiliary tools for preventing rotation.
[0004]
Therefore, an example of a technical disclosure of an auxiliary tool for preventing the attachment and rotation of a board anchor is a tightening tool disclosed in Japanese Utility Model Publication No. 58-128883 shown in FIG. On the other hand, a plate-shaped anti-rotation aid as shown in FIG. These two techniques aim to quantitatively expand the board anchor and also prevent the board anchor from sinking into the material when the legs are expanded.
[0005]
The former, that is, Japanese Utility Model Publication No. 58-128883 shown in FIG. 8, forcibly fixes the head of a screw screwed in advance to the board anchor to the chuck of the article, forcing the material out of the plane. By pulling in the direction, the leg of the board anchor is mechanically expanded. After the expansion, the chuck can be removed from the screw by sliding the chuck in a direction perpendicular to the axis of the board anchor. Moreover, the board anchor does not sink into the material by pulling the screw head. Therefore, it is possible to always perform stable expansion regardless of the skill level of the operator. However, since this auxiliary tool for preventing rotation is composed of a plurality of parts, it is very expensive, and it is very expensive for general consumers who use only a small amount.
[0006]
On the other hand, in the latter, that is, in the plate-shaped rotation prevention auxiliary tool shown in FIG. 10, first, the screw previously screwed into the board anchor is once removed, and then the through hole of the plate-shaped rotation prevention auxiliary tool is removed. After the screw portion of the screw tool is inserted into the board anchor, the screw portion of the screw tool is again screwed into the anchor for board, and after the preparation for expansion is completed, the article is then inserted into the through hole of the material. Next, the driver bit is fitted to the cross fitting portion provided on the head of the screw. Thereafter, the driver bit is rotated, the rotational force is transmitted to the screw tool, and the legs are opened using the action of pulling the legs. After the expansion, the screw can be removed from the board anchor and removed from the insertion hole. This auxiliary tool can be provided to consumers at a very low cost since a single flat plate is press-molded. However, as described above, there is a problem that it takes a long time to prepare for attachment because it must be once removed from the board anchor only for preparation for attaching the screw. Also, because of the flat plate shape, it must be in direct contact with the material during installation and removal. In addition, the problem is that the surface of the material is damaged by the rotational force applied when the rotating driver bit comes into contact with the rotation prevention aid. On the other hand, in terms of safety, your fingers are attached to this rotation prevention aid. In such a case, there is a possibility of being cut by the above-mentioned rotational force.
[0007]
[Problems to be solved by the invention]
In view of the above, the present invention is intended to provide an inexpensive and multifunctional auxiliary device for preventing board attachment and rotation to the market in consideration of various aspects of convenience, safety, and supply price to the market.
[0008]
In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that the short piece portion 2 is composed of a main body portion having a substantially round shape composed of a long piece portion 1 and a short piece portion 2 formed by bending a single flat plate. The U-shaped opening 3 for inserting the flange 14 of the board anchor 8 and the gap 16 between the heads of the screw 15 toward the bent portion 18 is provided at the longitudinal end portion of the long piece portion 1. A configuration in which a drill blade 7 is provided at the end 2 opposite to the bent portion 18 is employed.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to examples of drawings. As shown in FIG. 1, the auxiliary device for preventing the attachment and rotation of the board anchor according to the present invention comprises a substantially U-shaped main body portion comprising a long piece portion 1 and a short piece portion 2 formed by bending a flat plate. Thus, a U-shaped opening 3 for inserting the flange 14 of the board anchor 8 and the gap 16 between the heads of the screw 15 toward the bent portion 18 is provided at the longitudinal end of the short piece portion 2. The configuration in which the drill blade 7 is provided at the end opposite to the bent portion 18 of the long piece portion 1 is employed. As shown in FIGS. 1 to 3, the drill blade 7 may be any shape that can be drilled in the material. Further, as shown in FIG. 3, the long piece portion 1 can be rounded so as to converge toward the end opposite to the bent portion 18 of the long piece portion to form a drill blade.
[0010]
First, in order to drill the pilot hole 10 in the material 9, it is necessary to prepare a drill suitable for the board anchor with the drill. Accordingly, in the present application, the board anchor attachment / rotation prevention auxiliary tool drill blade 7 according to claim 1 is used.
[0011]
In order to drill a pilot hole in the material, as shown in FIG. Thereafter, the auxiliary tool is rotated to drill a pilot hole.
[0012]
Next, the board anchor 8 prepared in advance as shown in FIG. When inserting, it is preferable that the screw 15 is unscrewed and a gap 16 is provided between the head of the screw 15 and the flange 14.
[0013]
Thereafter, as shown in FIG. 7, the board anchor anchoring and preventing auxiliary tool of the present application is re-gripped, and the U-shaped opening 3 provided in the short piece 2 in the gap between the flange 14 and the head of the screw 15. Insert as if applying. After insertion, the head of the screw is rotated by the driver bit 17. At this time, it is preferable to press the short piece portion 2 against the flange 14 in order to prevent rotation due to the rotation of the driver bit 17. Alternatively, the projection provided on the upper surface side 20 of the short piece portion 2 shown in another embodiment or the tongue piece 6 is fitted to the notch portion provided on the flange 14 to reliably prevent the rotation. be able to.
[0014]
On the other hand, as the driver bit 17 rotates, the leg portion of the board anchor 8 opens and the fixing to the material 9 is completed. After the fixing is completed, the screw tool is unscrewed and the board anchor attachment / rotation prevention auxiliary tool is removed.
[0015]

【The invention's effect】
As described above, it is possible to use for drilling a pilot hole without using time and effort to prepare for mounting a board anchor as in the prior art by using the auxiliary tool for preventing the mounting and rotation of the board anchor according to the present invention. It is possible to provide to consumers at low cost because it is composed of flat plate, and the surface of the material is damaged by holding and fixing the auxiliary tool for preventing rotation of the board anchor of the present invention with a finger. Nor. In addition, since the auxiliary tool for preventing rotation is held with his / her finger, the driver bit is not cut by the rotational force of the driver bit.
