BRAILLE RIVET AND INSTALLATION METHOD THEREFOR
To provide a braille rivet which makes it possible to suppress coming off a fitting surface.SOLUTION: A braille rivet 1 has a rivet body 11, and a leg 40 provided so as to extend downward from the rivet body 11. The leg 40 has a first part 41 including a thread part 41A having a screw thread 12A formed on an outer peripheral surface, and a second part 42 located under the first part 41 and projecting more outward in a radial direction of the leg 40 than the first part 41 so as to form a continuous convex part in the circumferential direction of the leg 40. The braille rivet 1 is provided with a rivet member 10 including the rivet body 11 and a rivet leg 12 extending from the rivet body 11 and having a screw thread 12A formed on an outer peripheral surface, a nut member 20 having a thread groove formed on an inner peripheral surface, to which the rivet leg 12 is threadably fitted, and a rod screw 30 having a screw thread formed on an outer peripheral surface. The rod screw 30 is threadably fitted to the nut member 20 from the opposite side of the rivet leg 12, and the nut member 20 connects the rivet leg 12 and the rod screw 30.SELECTED DRAWING: Figure 1
【課題】取付面から外れるのを抑制することができる点字鋲を提供する。【解決手段】点字鋲１は、鋲本体１１と、鋲本体１１から下方に延びるように設けられた脚部４０とを有する。脚部４０は、外周面にねじ山１２Ａが形成されたねじ部４１Ａを含む第１部分４１と、当該第１部分４１の下側で第１部分４１よりも脚部４０の径方向外側に突出し、脚部４０の周方向に連続した凸部を形成する第２部分４２とを有する。点字鋲１は、鋲本体１１と、鋲本体１１から延出し、外周面にねじ山１２Ａが形成された鋲脚部１２とを有する鋲部材１０と、内周面にねじ溝が形成され、鋲脚部１２が螺嵌するナット部材２０と、外周面にねじ山が形成された棒ねじ３０とを備える。棒ねじ３０は、鋲脚部１２とは反対側からナット部材２０に螺嵌し、ナット部材２０は、鋲脚部１２と棒ねじ３０を連結している。【選択図】図１
