JPH0719612U - Wood screw - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a wood screw that can be easily fastened and easily removed. [Structure] The taper-shaped main body 1 provided with a screw portion 4 is provided with a notch 5 along the longitudinal direction that is open at the tip and the peripheral surface. [Effect] When the main body is hammered into the small hole formed at the tightening location, it can be easily and reliably tightened by elasticity. When removed, it can be removed easily with a screwdriver, and work efficiency is significantly improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to wood screws.

[0002]

[Prior art]

 With conventional wood screws, a small hole is made at the tightening point, and then the wood screw is inserted into the small hole and tightened with a screwdriver. Therefore, when there are a large number of tightening points, there are drawbacks such as the labor required for operation by the driver and the work efficiency being hindered.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a wood screw which can be mounted quickly and easily and which can surely have a tightening action.

[0004]

[Means for Solving the Problems]

 The means of the present invention are as follows. A cruciform cut that is formed integrally with a head having a driver engagement groove and has a threaded portion that tapers toward the tip and that opens to the tip and the circumferential surface along the length of the body. A wood screw characterized by having elasticity and giving elasticity to the main body.

[0005]

[Action]

 By opening a small hole in the tightening portion with a wood screw and driving the main body 1 into the small hole, it is not necessary to tighten the screw with a driver, and the screw can be immediately tightened. And when removing it, you can pull it out immediately by turning the body lightly around with a driver.

[0006]

【Example】

 In the figure, 1 is a main body, 2 is a head formed on the upper end of the main body 1, and an engaging groove 3 into which the tip of a driver is fitted is provided. The main body 1 has a threaded portion 4 which gradually becomes thinner toward the tip, and a cross-shaped notch 5 which is opened from the upper part of the main body 1 to the tip and the peripheral surface is provided to impart elasticity to the body 1. There is.

[0007]

[Effect of device]

 According to the present invention, it is not necessary to rotate the main body by a driver one by one as in the prior art to gradually advance the screw, but by simply driving the main body into the small hole, the elasticity of the main body caused by the notch makes it easier and more reliable. Can be fastened. It is also easy to remove and the work efficiency is significantly improved.

Claims (1)

[Scope of utility model registration request] 1. A main body having a threaded portion which becomes gradually narrower toward the tip is integrally formed with a head having a driver engaging groove, and is opened to the tip and the peripheral surface along the longitudinal direction of the body. A wood screw characterized by having a V-shaped cut to give elasticity to the main body.
