Abstract

この意匠に係る物品は、脱落防止ねじであって、例えば2枚のパネルを組み立てる際に使用されるものである。使用時には、まず、使用状態を示す参考図1に示すように、1枚目の板に本物品を螺合する。次に、ねじの先端部で2枚目の板の穴を探りながら、フローティングナットで固定する。ここで、大型パネルを組み立てる際には、1枚目の板に設けられたねじ穴の位置と2枚目の板に設けられた穴の位置とがずれることがある。本物品のねじ頭下面には曲面が設けられると共に、ねじ頭とねじ部との間に設けられた非ねじ部がねじ部外径よりも小径に設けられている。そのため、使用状態を示す参考図1のように、1枚目の板の穴越しに2枚目の板に設けられた穴の位置を視認できない状態でも2枚目の板に設けられた穴を探りやすい。また、使用状態を示す参考図2に示すように、板に対して本物品が傾いた状態であっても、ねじ頭下面の曲面と球面座金上面に設けられた曲面とが面接触するために、ねじをしっかりと固定することができる。The article according to this design is a captive screw, which is used, for example, when assembling two panels. When using the article, first, as shown in Reference Figure 1 showing the state of use, the article is screwed into the first plate. Next, the tip of the screw is used to search for a hole in the second plate, and the article is fixed with a floating nut. Here, when assembling a large panel, the position of the screw hole in the first plate may be misaligned with the position of the hole in the second plate. The article has a curved surface on the underside of the screw head, and the non-threaded portion between the screw head and the threaded portion is smaller in diameter than the outer diameter of the threaded portion. Therefore, as shown in Reference Figure 1 showing the state of use, it is easy to search for the hole in the second plate even when the position of the hole in the second plate cannot be seen through the hole in the first plate. In addition, as shown in Reference Figure 2 showing the state of use, the screw can be firmly fixed even when the article is tilted relative to the plate, because the curved surface of the underside of the screw head and the curved surface on the upper surface of the spherical washer are in surface contact with each other.
