Abstract

<P>PROBLEM TO BE SOLVED: To provide a screw ensuring proper fastening strength using a screwdriver capable of fastening even phillips screws, while solving the problem wherein the heads of slot and phillips screws are likely to be deformed making it difficult to do work at deep parts and to provide a V-slot screw enabling work at deep parts and being usable with conventional screwdrivers. <P>SOLUTION: The V-slot screw A provided with a slot at the top of a V-slot to enable use of a conventional flathead screwdriver has a sufficiently large contact area so that, using a screwdriver B for work at deep parts, it enables work at deep parts. The V-slot screw A1 permits proper fastening, with the screwhead resistant to deformation, since a force is evenly applied by a V-slot-screw fastening driver D capable of handling phillips screws. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は、ネジ類の頭部に逆三角形又は台形で谷形のネジ溝を設け三角形又は台形の山形のドライバーで締結部を適正に締め付けられる。谷ネジ上部にマイナス溝を設け従来のマイナスドライバーも使用可能で深奥部の作業もドライバーとネジの接触面が多いので作業が容易である。またプラスネジを締め付けることも出来る技術に関するものである。
【0002】
【従来の技術】
従来のプラス及びマイナスネジは締め付け時にネジの頭部が変形するなどの欠点があった。プラスネジはマイナスドライバーが使用できなかった
【0003】
【発明が解決しようとする課題】
従来のマイナス・プラスネジは頭部が変形しやすい欠点がありネジの頭部の形状により締め付け過ぎてネジが折れる事があった。深奥部の作業が容易でなかった本発明はこれらの欠点を除く為になされたものである。
【0004】
【課題を解決するための手段】
上記目的を達成する為ネジ頭部に逆三角形又は台形の谷形溝を設け三角形又は台形の山形ドライバーを使用して締め付け、緩める作業を行う。従来のマイナスドライバーも使用できるように谷形溝の上部にマイナス溝を設け深奥部の作業もネジとドライバーの接触面多いので容易になった
【0005】
本発明は、谷山形の締め付け部で谷山全体に均等な力が掛りネジ頭部の変形が避けられ山形ドライバーでプラスネジを締め付け緩めることが可能である。
【0006】
【発明の実施の形態】
以下本発明の実施の形態については図1谷ネジ上部にマイナス溝を設け従来ドライバーも使用できドライバーとネジの接触面が多いので深奥部の作業が容易な谷形ネジAを深奥部作業用山形ドライバーBで同ネジを締め付ける図2は同ネジの頭部である図3は同ネジの正面断面図であり図4は同ネジの側面断面図である。図5は谷ネジ頭部の図で図6は正面断面図である図7は側面断面図である図5〜図7のネジA1は頭部が変形し難く適正な締め付け強度を得ることが出来る図8は図5〜図7のネジを山形ドライバーで締め付ける図でプラスネジの締め付けも出来る。
【0007】
【発明の効果】
ネジ頭部が変形しにくい、適正な締め付け強度が得られる、プラスネジを山形ドライバーで締め付け及び緩められ、ドライバーとネジの接触面積が大きいので作業のしにくい深奥部の作業がしやすい、構造が簡単であり製造しやすい。また谷溝の上部にマイナス溝を設けたネジもあるので従来の様にマイナスドライバーを使用可能である

TECHNICAL FIELD OF THE INVENTION
According to the present invention, an inverted triangular or trapezoidal valley-shaped screw groove is provided on the head of the screw, and the fastening portion can be properly tightened with a triangular or trapezoidal angled screwdriver. A flat slot is provided at the top of the root screw, and a conventional slotted screwdriver can also be used. Work at the deep part is easy because there are many contact surfaces between the screwdriver and the screw. Also, the present invention relates to a technique capable of tightening a Phillips screw.
[0002]
[Prior art]
Conventional plus and minus screws have drawbacks such as deformation of the screw head when tightened. The Phillips screw could not be used with a flathead screwdriver.
[Problems to be solved by the invention]
The conventional minus / plus screw has a disadvantage that the head is easily deformed, and the screw may be broken due to excessive tightening due to the shape of the screw head. The present invention has been made to eliminate these drawbacks, since the work in the deep part was not easy.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, an inverted triangular or trapezoidal valley-shaped groove is provided in the screw head and tightening and loosening are performed using a triangular or trapezoidal angled screwdriver. A flat slot is provided at the top of the valley groove so that a conventional slotted screwdriver can also be used.
According to the present invention, a uniform force is applied to the entire valley at the valley-shaped tightening portion, the deformation of the screw head is avoided, and the phillips screw can be tightened and loosened by the valley screwdriver.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an embodiment of the present invention in which a flat groove is provided at the top of a valley screw, a conventional screwdriver can be used, and there are many contact surfaces between the screwdriver and the screw. FIG. 2 is a head sectional view of the screw, FIG. 3 is a front sectional view of the screw, and FIG. 4 is a side sectional view of the screw. FIG. 5 is a view of a valley screw head, FIG. 6 is a front cross-sectional view, FIG. 7 is a side cross-sectional view, and the screw A1 in FIGS.
