PROBLEM TO BE SOLVED: To provide a method for opening holes for suspension on a bedcover in which a circumferential edge of the hole does not loose.SOLUTION: On a bedcover 1, an assist hole opens which continues from a front surface 1a to a back surface 1b. On a circumferential edge of the assist hole on the front surface 1a of the bedcover 1 and a circumferential edge of the assist hole on the back surface 1b, a reinforcing sheet are bonded to close the assist holes and prevent loosening of the edges of the assist holes. Then, a hole smaller than an inner diameter of the assist hole is opened on each of the reinforcing sheet to serve as a hole for suspension tool which continues from the front surface 1a to the back surface 1b of the bedcover 1.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】穴の周縁がほどけることがない吊り具通し穴を上掛けにあける上掛けの吊り具通し穴をあける方法。【解決手段】寝具の上掛け1に、その表面1aから裏面1bに連続した補助穴をあけ、前記上掛け1の表面1aにおける前記補助穴の周囲と、裏面1bにおける前記補助穴の周囲に補強シートをそれぞれ貼り付けて前記補助穴を閉塞して補助穴の周縁がほどけないようにし、前記各補強シートに前記補助穴の内径よりも小径の穴をあけることで前記上掛け1の表面1aから裏面1bに連続した吊り具通し穴とする寝具の上掛けに吊り具通し穴をあける方法。【選択図】図3
