    • An apparatus for adaptive use with a single-cylinder deadbolt assembly prevents retraction of the extended deadbolt by a key, when the apparatus is in the engaged position. Thus the door will remain locked despite the attempted use of a key for the deadbolt on the outside of the door. The apparatus includes a cylindrical, hollow frame mounted on the security side of the door, the frame including an engaged-fixing site and a retracted-fixing site. A cylindrical security member is received within the frame, the security member having a thumb latch-engaging member including two tines formed on the operational end. A screw or other fixing member is removably received by both the frame and security member at one of the two sites. The security member may be positioned so that the thumb latch-engaging member is in an extended position relative to the thumb latch, and the screw is reversibly fixed in the engaged-fixing site so as to fix the security member and prevent axial shifting of the security member relative to the frame, causing the thumb latch-engaging member of the security member to restrict the thumb latch from operational rotation and therefore the deadbolt may not be retracted by means of a key.
    • 当装置处于接合位置时,用于使用单缸锁舌组件进行自适应使用的装置防止通过钥匙延伸的延伸锁舌的缩回。 因此,尽管尝试使用钥匙在门外的死栓,门仍将保持锁定。 该装置包括安装在门的安全侧的圆柱形中空框架,该框架包括接合固定位置和缩回固定位置。 圆柱形安全件被容纳在框架内,安全件具有拇指闩锁接合构件,其包括在操作端形成的两个尖齿。 螺钉或其他固定构件在两个位置中的一个位置处由框架和安全构件可拆卸地接收。 安全构件可以被定位成使得拇指闩锁接合构件相对于拇指闩锁处于延伸位置,并且螺钉可逆地固定在接合固定位置中,以便固定安全构件并防止安全构件的轴向移动 安全构件相对于框架,使得安全构件的拇指闩锁接合构件限制拇指闩锁的操作旋转,因此闩锁可能不能通过键缩回。
