Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem wherein a shape of a publicly known cross-tip screwdriver bit allows a screw, a machine screw and the bit to easily slip out of a fitting groove at threadably attaching work. <P>SOLUTION: A recessed groove up to 2.0 mm to 5.0 mm is successively arranged from the tip of a blade in the depth of the fitting groove of the screw and the bit. Grounding surfaces with the screw and the machine screw are formed in a plane shape to prevent slipping-out of a bit tip part from the fitting groove and collapse of a screw groove. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【発明の属する技術分野】
本発明は、プラスドライバービットの形状に関するものである。
【0002】
【従来の技術】
従来から提案されている図1に示すビット先端部に平面視十字形状の刃21、22、23、24を有するプラスドライバービットは、諸先端部の刃21、22、23、24がテーバー状に形成されている。これは、ネジ・ビス等の嵌入溝への挿入を良好にするとともに、当該嵌入溝から抜け易くするためである。
【0003】
【発明が解決しようとする課題】
ところが、公知のプラスドライバービットではその構造故に、木製品等へネジ・ビスを挿入しようとした場合にネジ・ビス等の中心軸のぶれによって、当該嵌入溝からプラスドライバービットが外れやすくなり、当該嵌入溝を潰し、または過失による自傷を負う場合がある。よって本発明はこれらのことを前提に、ネジ・ビス等の嵌入溝へ挿入されたビットの先端部が従来品に比し、力を加えた場合に密着性、安定性を向上させ、ネジ・ビス等の螺着作業を良好かつ安全に行うことができるプラスドライバービットを提供することを課題とする。
【0004】
【課題を解決するための手段】
以上の課題を解決するために、図2、3に示した形成平面部分5を設けたことを特徴とするプラスドライバービットである。
【0005】
【発明の実施の形態】
添付図面を参照して本発明の要旨を説明すると、本発明は刃1、2、3、4に形成平面部分5が一体的に設けられている。
【0006】
「実施形態の効果」
形成平面5がネジ・ビス等とビットの密着性を向上させ、ネジ・ビス等の螺着作業時に中心軸のぶれを最小限に抑えてネジ・ビス等とビットの外れが可及的に防止され、かつ安定したビットへの力の伝達が可能になる。
【0007】
「他の実施形態」
尚、本実施例に係るビットは、刃1、2、3、4及び平面5をプレス加工により形成しているが、マイナスドライバービットに関しても同様の考え方であり、また棒状部材の先後両端に4枚の刃1、2、3、4を形成して成る通称ダブルビットと呼ばれるプラス、マイナスドライバービットに採用しても良いのは勿論である。
【0008】
【発明の効果】
以上説明したように、本発明によれば、ネジ・ビス等の嵌入溝へ挿入されたビットの先端部が従来品に比し、力を加えた場合に密着性、安定性を向上させ、ネジ・ビス等の螺着作業を良好かつ安全に行うことができる画期的なプラスドライバービットとなる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to the shape of a Phillips screwdriver bit.
[0002]
[Prior art]
The conventionally proposed Phillips screwdriver bit having a cross-shaped blade 21, 22, 23, 24 at the tip of the bit shown in FIG. 1 has blades 21, 22, 23, 24 of various tips in a Taber shape. Is formed. This is to make it easier to insert screws and screws into the fitting grooves and to make it easy to get out of the fitting grooves.
[0003]
[Problems to be solved by the invention]
However, due to the structure of the known Phillips screwdriver bit, when the screw or screw is to be inserted into a wooden product or the like, the center axis of the screw or screw is displaced, so that the Phillips screwdriver bit tends to come off from the fitting groove. The groove may be crushed or negligence may cause self-harm. Therefore, the present invention presupposes these facts, and improves the adhesion and stability when a force is applied to the tip of the bit inserted into the fitting groove of the screw or screw, as compared with the conventional product, and improves the An object of the present invention is to provide a Phillips screwdriver bit capable of performing a screwing operation of a screw or the like satisfactorily and safely.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a plus driver bit is provided with the formation plane portion 5 shown in FIGS.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The gist of the present invention will be described with reference to the accompanying drawings.
[0006]
"Effects of the embodiment"
The forming plane 5 improves the adhesion between the screw and the screw and the bit, and minimizes the deviation of the central shaft during the screwing work of the screw and the screw to prevent the screw and the screw and the bit from coming off as much as possible. And stable power transmission to the bit.
[0007]
"Other embodiments"
In the bit according to the present embodiment, the blades 1, 2, 3, 4 and the flat surface 5 are formed by pressing, but the same concept is applied to the flathead screwdriver bit. Needless to say, the present invention may be applied to a plus and minus driver bit called a double bit formed by forming the blades 1, 2, 3, and 4.
[0008]
【The invention's effect】
As described above, according to the present invention, the tip of the bit inserted into the fitting groove such as a screw or a screw has improved adhesion and stability when a force is applied as compared with the conventional product, -An epoch-making Phillips screwdriver bit that allows screwing work such as screws to be performed successfully and safely.
[Brief description of the drawings]
FIG. 1 is a plan view of a conventional Phillips screwdriver bit.
FIG. 2 is a plan view of the present embodiment.
FIG. 3 is a perspective view of the present embodiment.
