Abstract:
(EN) The present invention relates to a cover member (1) made of chemically strengthened glass for protecting an object to be protected, the cover member (1) being characterized by: at least one recessed part (7) being provided on at least one of a first main surface (3) and a second main surface (5) of the cover member (1); the cover member (1) integrally comprising a thin part (13) formed by the recessed part and a thick part (17) connecting with the thin part (13); and, defining tensile stress as positive and compressive stress as negative, the integral value S for main stress difference in the through-thickness direction of the thin part (13) at the position of the center of gravity of the thin part being less than 0 MPa.
(FR) La présente invention concerne un élément de couvercle (1) en verre renforcé chimiquement pour protéger un objet à protéger, l'élément de couvercle (1) étant caractérisé par : au moins une partie évidée (7) disposée sur au moins une surface parmi une première surface principale (3) et une seconde surface principale (5) de l'élément de couvercle (1) ; l'élément de couvercle (1) comprenant d'un seul tenant une partie mince (13) formée par la partie évidée et une partie épaisse (17) reliée à la partie mince (13) ; et, définissant une contrainte de traction en tant que positive et une contrainte de compression en tant que négative, la valeur intégrale S pour la différence de contrainte principale dans la direction de l'épaisseur de la partie mince (13) à la position du centre de gravité de la partie mince étant inférieure à 0 MPa.
(JA) 本発明は、保護対象を保護する化学強化ガラスからなるカバー部材(1)であって、カバー部材(1)の第1の主面(3)または第2の主面(5)の少なくとも一方には、少なくとも一つの凹部(7)が設けられ、カバー部材(1)は、凹部により形成された薄肉部(13)と、薄肉部(13)に接続する厚肉部(17)と、を一体に備え、引張応力を正、圧縮応力を負とした場合、薄肉部重心位置における薄肉部(13)の板厚方向における主応力差の積分値Sが、0MPa未満となることを特徴とするカバー部材(1)に関する。
