A nut is embedded at a position corresponding to the hole, a screw is screwed into the nut embedded in the rear support frame from the through hole, and a plug is fitted to one end of the tubular body forming the armrest, Realized the purpose of preventing the screws used in the folding chair from protruding on the surface and damaging the user.
The folding chair having such a configuration will be described below with reference to specific examples in order to describe the structure and features in detail.

この考案による折り畳み椅子は、図１に開示するように交差して連結した折り畳み可能な脚部フレームセット１０と、脚部フレームセットの中間に設ける座部２０と、脚部フレームセット１０の上端に設ける背もたれセット３０と、脚部フレームセット１０の左右両側にそれぞれ設けられる肘掛４０とによってなる。 A folding chair according to the present invention includes a foldable leg frame set 10 that is cross-coupled as disclosed in FIG. 1, a seat 20 provided in the middle of the leg frame set, and an upper end of the leg frame set 10. The backrest set 30 is provided, and the armrests 40 are provided respectively on the left and right sides of the leg frame set 10.

図２から４に開示するように、脚部フレームセット１０は軸桿１１を支軸として、左右２本の前支持フレーム１２と、左右２本の後支持フレーム１３とを軸支する。左右２本の後支持フレーム１３には、適宜な位置にナット１３１を埋設する。また、軸桿１１の両端縁部にはそれぞれ左ネジ山１１１と、右ネジ山１１２とを螺刻する。また、軸桿１１の中間の位置は断面が楕円状を呈する扁平部１１３を形成する。 As disclosed in FIGS. 2 to 4, the leg frame set 10 supports two left and right front support frames 12 and two left and right rear support frames 13 with a shaft rod 11 as a support shaft. Nuts 131 are embedded at appropriate positions in the left and right rear support frames 13. Further, a left screw thread 111 and a right screw thread 112 are threaded on both ends of the shaft rod 11, respectively. In addition, a flat portion 113 having an elliptical cross section is formed at an intermediate position of the shaft rod 11.

上述する構造によって、軸桿１１と、前支持フレーム１２と、後支持フレーム１３とを組み立てる場合、軸桿１１を前支持フレームに貫通させ、工具で軸桿１１の扁平部１１３を挟み、軸桿を回転させて左ネジ山１１１、右ネジ山１１２を後支持フレーム１３に埋設したナット１３１に螺合させる。このため、脚部フレームセット１０には外部に突起したネジの頭部が見られなくなる。 When the shaft 11, the front support frame 12, and the rear support frame 13 are assembled by the structure described above, the shaft 11 is penetrated through the front support frame, the flat portion 113 of the shaft 11 is sandwiched with a tool, and the shaft And the left screw thread 111 and the right screw thread 112 are screwed onto the nut 131 embedded in the rear support frame 13. For this reason, the head part of the screw | thread which protruded outside cannot be seen in the leg part frame set 10. FIG.

図５から７に開示するように、背もたれセット３０は背もたれ本体３１と、中蓋３２と、前部化粧板３３とによってなる。背もたれ本体３１は、くりぬき部を形成したハウジングであって、水平方向の両端縁部に貫通孔３１１を形成し、該貫通孔に後支持フレーム１３の上端を挿通させ、更に中蓋３２を取りつけ、複数のネジ３２１で背もたれ本体３１を後支持フレーム１３の上端に固定する。また、中蓋３２には係合孔３２２を形成し、前部化粧板３３には中蓋３２の係合孔３２２に対応する位置に係合突起３３１を形成し、前部化粧板３３の係合突起３３１を中蓋３２の係合孔３２２に嵌挿して前部化粧板３３を固定する。よって、ネジ３２１の頭部が前部化粧板３３によって内部に隠され、背もたれセット３０の表面が平坦になる。よって、ネジの頭部で人体を傷つけることなく安全性を高めることができる。 As disclosed in FIGS. 5 to 7, the backrest set 30 includes a backrest main body 31, an inner lid 32, and a front decorative plate 33. The backrest body 31 is a housing in which hollow parts are formed, and through holes 311 are formed at both edge portions in the horizontal direction, the upper end of the rear support frame 13 is inserted into the through holes, and an inner lid 32 is attached. The backrest body 31 is fixed to the upper end of the rear support frame 13 with a plurality of screws 321. Further, an engagement hole 322 is formed in the inner lid 32, and an engagement protrusion 331 is formed in the front decorative plate 33 at a position corresponding to the engagement hole 322 of the intermediate cover 32, so that the front decorative plate 33 is engaged. The front protrusion plate 33 is fixed by inserting the mating protrusion 331 into the engagement hole 322 of the inner lid 32. Therefore, the head of the screw 321 is hidden inside by the front decorative plate 33, and the surface of the backrest set 30 becomes flat. Therefore, safety can be improved without damaging the human body with the head of the screw.

図８、９に開示するように、肘掛４０は管体を湾曲させてなり、一端の壁面に貫通孔４１を穿設する。また、後支持フレーム１３には肘掛４０の貫通孔４１に対応する位置にナット１３２を埋設し、ネジ４２を肘掛４０の貫通孔から後支持フレーム１３に埋設したナット１３２に螺合させる。更に、肘掛４０を形成する管体の一端には栓４３を嵌着する。よって、ネジの頭部が管体内に隠される。 As disclosed in FIGS. 8 and 9, the armrest 40 is formed by bending a tubular body, and a through hole 41 is formed in a wall surface at one end. A nut 132 is embedded in the rear support frame 13 at a position corresponding to the through hole 41 of the armrest 40, and a screw 42 is screwed into the nut 132 embedded in the rear support frame 13 from the through hole of the armrest 40. Further, a stopper 43 is fitted to one end of the tube forming the armrest 40. Therefore, the screw head is hidden in the tube.

以上はこの考案の好ましい実施例であって、この考案の実施の範囲を限定するものではない。よって、当業者のなし得る修正、もしくは変更であって、この考案の精神の下においてなされ、この考案に対して均等の効果を有するものは、いずれも本考案の実用新案登録請求の範囲に属するものとする。 The above is a preferred embodiment of the present invention, and does not limit the scope of implementation of the present invention. Therefore, any modifications or changes that can be made by those skilled in the art, which are made within the spirit of the present invention and have an equivalent effect on the present invention, belong to the scope of the utility model registration claim of the present invention.
