    • A security door comprises first and second vertical door jambs spaced from one another to define a doorway therebetween, and a door for closing the doorway. The second door jamb has a generally channel-shaped recess therein extending generally vertically from adjacent the bottom of the jamb to adjacent the top of the jamb. The security door includes a hinge on the first door jamb for supporting the door adjacent one vertical edge of the door, constituting its inner edge. The hinge enables the door to swing on a generally vertical axis between an open position wherein the door is swung out of the doorway and a closed position wherein the door closes the doorway and the opposite vertical edge of the door, constituting its outer edge, is spaced inwardly from the recess in the second door jamb. The door is movable outwardly in the plane of the doorway from its closed position to a secured position wherein the outer vertical edge is received in the vertical recess thereby to prevent the door from swinging out of its secured position. The security door further includes springs for urging the door away from its secured position and locking apparatus operable to pull the outer vertical edge of the door into the vertical recess and to maintain the door in its secured position against the urging of the springs. The locking apparatus comprises cooperable locking components in the door and the second door jamb.
    • 安全门包括彼此间隔开以在其间限定门口的第一和第二垂直门边框,以及用于关闭门口的门。 第二门侧柱具有大致通道形的凹槽,其大体上垂直地从侧柱的底部垂直延伸到邻近顶部的顶部。 安全门包括在第一门支柱上的铰链,用于支撑与门的一个垂直边缘相邻的门,构成其内边缘。 铰链使得门能够在门从门口摆出的打开位置和闭合位置之间在大致垂直的轴线上摆动,其中门关闭门口和构成其外边缘的门的相对的竖直边缘是闭合位置 与第二门侧柱的凹部间隔开。 门能够在门口的平面中从关闭位置向外移动到固定位置,其中外部垂直边缘被容纳在垂直凹部中,从而防止门从其固定位置摆动。 安全门还包括用于将门推离其固定位置的弹簧和可操作以将门的外部垂直边缘拉入垂直凹部并且将门保持在其固定位置以抵抗弹簧的推动的锁定装置。 锁定装置包括门中的可配合的锁定部件和第二门侧柱。
