摘要： A combination lock for a key safe has an over-center spring for biasing a unitary bolt in an extended or retracted position. A switch for actuating the bolt has a break-away button to foil vandals. The bolt includes checkers for engaging notches in a plurality of programmable combination rings when the combination is properly dialed. The checkers have V-shaped ridges for engaging false notches formed in the combination rings, making the lock pick-resistant. The checkers also include flat shoulders to prevent the bolt from being forcibly wedged into the combination rings to open the lock. The combination must be properly dialed to permit the bolt to be retracted for closing the key safe.
摘要翻译：用于钥匙保险箱的组合锁具有用于将整体螺栓偏压在延伸或缩回位置的过中心弹簧。用于致动螺栓的开关具有折断按钮以折断破坏者。当组合被正确拨号时，螺栓包括用于在多个可编程组合环中接合凹口的检查器。检查器具有用于接合形成在组合环中的假凹口的V形脊，使得锁定防止。检查者还包括平肩，以防止螺栓被强行楔入组合环以打开锁。必须正确拨打组合以允许螺栓缩回以关闭钥匙保险箱。

摘要： Various enhancements are provided to a pushbutton lock to enhance its security. One is the provision of button tips that are mounted on the ends of the button assemblies and spring-loaded to protrude from the face of the lock, regardless of whether the underlying button is "in" or "out." By this arrangement, a bystander cannot readily see the button combination by the pattern of depressed buttons. This arrangement also reduces tactile feedback between the underlying button assembly and the externally available button tips, increasing resistance to pick attacks. A further enhancement is the provision of button bars between adjacent pairs of button tips. Whenever any of the button tips is manually depressed, the corresponding button bar is pressed into engagement with, and prevents movement of, a member that must be moved in order to unlock the lock. This arrangement further increases lock security by preventing an attacker from experimentally pressing buttons and judging the tactile effect thereon in attempted unlockings of the lock.
摘要翻译：提供了对按钮锁的各种增强以增强其安全性。一个是提供安装在按钮组件的端部上的按钮尖端，并且弹簧加载以从锁的表面突出，而不管下面的按钮是“进入”还是“外出”。通过这种布置，旁观者不能通过按下按钮的图案容易地看到按钮组合。这种布置还减少了底层按钮组件和外部可用的按钮尖端之间的触觉反馈，增加了对拾取攻击的抵抗力。进一步的增强是在相邻的按钮尖端之间提供按钮杆。无论何时手动按下任何按钮提示，相应的按钮条被压入与必须移动的构件的卡合，并阻止其移动以解锁锁定。这种安排通过防止攻击者实验地按下按钮并在尝试解锁锁定时判断其触觉效果，进一步提高了锁的安全性。

摘要： A lock includes a face plate into which a lock cylinder is mounted. Extending from the rear side of the face plate is a frame for supporting the back of the lock cylinder. A cover plate covers the front of the lock cylinder and includes one or more arms extending through the face plate to the back thereof, where the arms are secured against the plate. By this arrangement, the cover plate is secured to the back of the face plate, preventing removal of the lock cylinder by prying. The frame secures the lock cylinder to the rear, preventing it from being dislodged by hammer blows. Against all such attacks, the full structural integrity of the face plate serves to keep the lock cylinder in place and the lock secure.
