ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a plate-shaped fastener for mounting a member or an instrument to e.g. a wall made of plasterboard by means of screws.
A conventional method for mounting members or instruments to a wall so constructed as to be not accessible to its back comprises drilling a hole in the wall, inserting a plug into the hole, expanding the plug therein to form an engaging portion, and threading a screw into the plug to secure a member or an instrument to the wall.
Quality-wise, a plasterboard is brittle, so that the above conventional method, in which the plug is expanded in the hole of the wall to form an anchor, cannot provide strong resistance to pulling force and is low in tightening force. Thus, if the screw is tightened hard, the plug might turn together with the screw and come out.
An object of this invention is to provide a plate-shaped fastener which is high in resistance to pulling force, provides a firm tightening feeling, prevents idling, and which can firmly fix a member or an instrument to such a wall.
SUMMARY OF THE INVENTION
According to the invention, there is provided a plate-shaped fastener comprising a driving portion with a pointed tip, and an extension extending at an angle with respect to the driving portion with the rear end of the driving portion serving as a driving end, wherein the driving portion and the extension are integrally formed from a single bendable thin metal plate, the driving portion being formed with an engagement hole for a screw and the extension being formed with an insertion hole for the screw.
Other features and objects of the present invention will become apparent from the following description made with reference to the accompanying drawings, in which:
