Description
【０００１】[0001]
本考案は、各種部材を螺着する螺子に関する。 The present invention relates to a screw for screwing various members.
【０００２】[0002]
従来、各種部材を螺着する螺子は、図３，図４のように螺子本体２１とバネ座 金２２と平座金２３の３部品を組み合わせて構成され、螺子本体２１の内側の底 面は水平に形成されており、螺子軸２４にバネ座金２２と平座金２３を挿通して 螺着していた。 Conventionally, a screw for screwing various members is configured by combining three parts of a screw body 21, a spring washer 22 and a plain washer 23 as shown in FIGS. 3 and 4, and the inner bottom surface of the screw body 21 is horizontal. The spring washer 22 and the plain washer 23 were inserted into the screw shaft 24 and screwed.
【０００３】[0003]
しかしながら、上記従来例によると、螺子本体２１とバネ座金２２と平座金２ ３の３部品を組み合わせて締め付けたとき、螺子本体２１の内側の底面は水平に 形成されていたため、螺子本体２１の頭部の高さが高くなり、引っ掛かって、け がをする恐れがある他、外観が悪いという欠点があった。また、平座金２３の周 縁部の底面が断面直角に形成されているため、螺子を締め付けたとき、平座金２ ３の周縁部の底面で螺着する部材を傷付けてしまうという欠点があった。 However, according to the above-mentioned conventional example, when the screw main body 21, the spring washer 22, and the flat washer 23 are combined and tightened, the inner bottom surface of the screw main body 21 is formed horizontally, and therefore the head of the screw main body 21 is formed. The height of the part is high, there is a risk of being caught and injured, and the appearance is poor. In addition, since the bottom surface of the peripheral edge portion of the flat washer 23 is formed at a right angle in cross section, there is a drawback that when the screw is tightened, the member to be screwed on the bottom surface of the peripheral edge portion of the plain washer 23 is damaged. .
【０００４】 そこで本考案は、螺子の部品点数が少なく、螺子を締め付けたときに螺着する 部材を傷付けることのない螺子を提供することにある。Therefore, the present invention is to provide a screw having a small number of parts of the screw and not damaging a member to be screwed when the screw is tightened.
【０００５】[0005]
上記課題を解決するために、本考案は、螺子本体の頭部の周縁部を断面弧状に 形成し、螺子本体とバネ座金とを組み合わせて締め付けたとき、周縁部の底面と バネ座金の底面が同一面になるように断面傘状に頭部の内側の周縁部と螺子軸の 間にバネ座金収納溝を形成し、螺子本体とバネ座金の２部品で構成したものであ る。 In order to solve the above-mentioned problems, the present invention forms the peripheral portion of the head of the screw body in an arcuate cross section, and when the screw body and the spring washer are combined and tightened, the bottom face of the peripheral portion and the bottom face of the spring washer are A spring washer housing groove is formed between the inner peripheral edge of the head and the screw shaft so as to have the same plane and has an umbrella-shaped cross section, and is composed of two parts, a screw body and a spring washer.
【０００６】[0006]
螺子を締め付けると、バネ座金が螺子本体の頭部の内側に形成したバネ座金収 納溝に収納され、螺子本体の周縁部が平座金の役割を果たし、螺子が締め付けら れる。 When the screw is tightened, the spring washer is stored in the spring washer storage groove formed inside the head of the screw body, and the peripheral edge of the screw body acts as a flat washer, and the screw is tightened.
【０００７】[0007]
本考案に係る螺子の一実施例を添付図面に基づいて説明する。 An embodiment of the screw according to the present invention will be described with reference to the accompanying drawings.
【０００８】 図１は本考案に係る螺子の説明図、図２は本考案に係る螺子を締め付けた状態 の説明図であり、螺子本体１の頭部２の周縁部３を断面弧状に形成し、螺子本体 １とバネ座金４とを組み合わせて締め付けたとき、周縁部３の底面とバネ座金４ の底面が同一面になるように断面傘状に頭部２の内側の周縁部３と螺子軸５の間 にバネ座金収納溝６を形成し、螺子本体１とバネ座金４の２部品で構成している 。FIG. 1 is an explanatory view of a screw according to the present invention, and FIG. 2 is an explanatory view of a state in which the screw according to the present invention is tightened. A peripheral portion 3 of a head 2 of a screw main body 1 is formed in an arc cross section. When the screw main body 1 and the spring washer 4 are combined and tightened, the peripheral edge portion 3 inside the head 2 and the screw shaft have an umbrella-shaped cross section so that the bottom surface of the peripheral edge portion 3 and the bottom surface of the spring washer 4 are flush with each other. A spring washer housing groove 6 is formed between the two, and is composed of two parts, a screw body 1 and a spring washer 4.
【０００９】 螺子を締め付けると、バネ座金４が螺子本体１の頭部２の内側の周縁部３と螺 子軸５の間に形成したバネ座金収納溝６に収納され、螺子本体１の断面弧状に形 成した周縁部３が平座金の役割を果たし、螺子が締め付けられる。When the screw is tightened, the spring washer 4 is housed in the spring washer housing groove 6 formed between the inner peripheral portion 3 of the head 2 of the screw body 1 and the screw shaft 5, and the cross section of the screw body 1 is arcuate. The peripheral portion 3 formed in the shape plays the role of a plain washer, and the screw is tightened.
【００１０】[0010]
以上説明したように、本考案に係る螺子は、螺子本体の頭部の周縁部を断面弧 状に形成し、螺子本体とバネ座金とを組み合わせて締め付けたとき、周縁部の底 面とバネ座金の底面が同一面になるように断面傘状に頭部の内側の周縁部と螺子 軸の間にバネ座金収納溝を形成し、螺子本体とバネ座金の２部品で構成したもの であるため、螺子を締め付けたとき、頭部の高さが低くなる他、螺着する部材を 傷付けることがない等の優れた効果を有するものである。 As described above, the screw according to the present invention is such that when the peripheral portion of the head of the screw body is formed in an arcuate cross section and the screw body and the spring washer are combined and tightened, the bottom surface of the peripheral portion and the spring washer are tightened. Since a spring washer housing groove is formed between the inner peripheral edge of the head and the screw shaft so that the bottom surface of the head is flush with the cross section, it is composed of two parts: the screw body and the spring washer. When the screw is tightened, the height of the head is lowered, and the member to be screwed is not damaged, which is an excellent effect.
