| 摘要 |
The present invention provides an espagnolette locking system comprising an espagnolette locking mechanism including at least one locking pin 1 mounted on a slider 2, and operated by a handle engaging at 12 into a rotary driving member, such as a cam or pinion 11 or lever acting to convert the rotational handle movement to linear movement of the slider. The rotary driving member has integrally formed thereon or integrally assembled thereto a deadbolt 14 whereby the rotational movement of the rotary driving member simultaneously rotationally deploys the deadbolt 14 to engage in a keep. The mechanism can have means to indicate the state of the lock as well as means to produce a sound (such as a finger 19 engaging over teeth 20) as the mechanism is operated. Keep structures can be provided with camming ramps to engage centring pins on the slider, latches to engage further locking pins on the slider and biasing springs to increase door/window sealing. The slider can operate shoot bolt mechanisms and an additional bolt may be mounted adjacent and parallel to each shoot bolt to engage a further keep releasably attached to the shoot bolt keep. The additional bolt may be axially adjustable. |
