Abstract: An adjustable magnetic door holder comprises an electromagnetic unit and an adjustable strike support which includes a base and an armature or strike plate. The strike plate is adjustably coupled to the base by a ball and socket joint carried by a cylindrical member supported for limited angular movement and axial translation relative to the base whereby wide variation of adjustment between the strike plate and base may be attained to facilitate precise alignment of the strike plate with the electromagnetic unit.

Abstract: A lock cylinder having an emergency function and including a housing containing a key-removable core supporting a rotatable key plug for driving a roll-back supported on the housing externally thereof. An axially movable control member received in the housing rearwardly of the key plug cooperates in one position with a stop lug associated with the housing to limit angular movement of the key plug and the roll-back in one and an opposite direction when an operating key is employed to operate the lock cylinder. An elongated emergency key is provided which extends through the key plug to engage and shift the control member to another position out of alignment with the stop lug to effect free rotation of the key plug and the roll-back in one and an opposite direction. The effective length of the emergency key is critical.

Abstract translation: 一种具有紧急功能的锁芯，并且包括壳体，该壳体包含支撑可旋转的钥匙插头的钥匙可拆卸的芯，用于驱动支撑在外壳上的外壳上的回卷。 容纳在钥匙插头后部的壳体中的可轴向移动的控制构件在一个位置与与壳体相关联的止动凸耳配合，以在操作键为一个或相反方向时限制钥匙插头和回卷的角度运动 用于操作锁芯。 提供了一种细长的紧急钥匙，其延伸穿过钥匙插头以将控制件接合并移动到与停止凸耳不对准的另一位置，以实现钥匙塞和回卷在一个和相反方向上的自由旋转。 紧急钥匙的有效长度至关重要。
