Built-in safety latch mechanism for preventing sidewalk platform turnover door from rising without guardrail installation
In one example, a system is described. The system includes a guardrail having a post, and a post having a post claw. The system also includes a striker configured to be coupled to the turnover door. The system also includes a safety latch mechanism configured to be coupled to the fixed structure and including a body, a socket configured to receive the post, and a latch rotatably coupled to the body and biased in a latched position configured to engage with the striker to maintain the turnover door in the lowered position. Based on insertion of the post into the socket of the safety latch mechanism, the post pawl engages the latch and rotates the latch from the latched position to the unlocked position, allowing the flap door to rise from the lowered position to the raised position.
在一个示例中，描述了一种系统。该系统包括具有柱子的护栏，以及具有柱爪的柱子。该系统还包括构造成联接到翻转门的闩眼。该系统还包括安全闩锁机构，该安全闩锁机构被构造成联接到固定结构并包括主体、被构造成接收柱子的插口、以及门闩，该门闩可旋转地联接到主体并偏压在闩锁位置，该闩锁位置被构造成与闩眼接合，从而将翻转门保持在降低位置。基于柱子插入安全闩锁机构的插口中，柱爪与门闩接合并将门闩从闩锁位置旋转到解锁位置，从而允许翻转门从降低位置升高到升高位置。
