摘要： An unlatching tool to uncouple the trailer from the tractor of semi-trailer truck rigs, comprising a foldable elongated bar having a hand grasp at one end and a combination safety release arm plus unlatching hook at the opposite working end. The safety release arm extends at a right angle from the working end of the bar and in one direction from the bar, while the unlatching hook extends outwardly from the bar in the opposite direction and set back from the working end a short distance. When the unlatching hook engages the coupling latch which locks the king pin of the trailer to the tractor, the safety release arm extends forward of the unlatching hook just far enough to bear against the safety release mechanism which can be moved to the safety release position by a partial rotation or twist of the bar while at the same time pulling on the bar to draw the coupling latch to the unlatched position. The trailer can then be uncoupled from the tractor. The previous way of unlatching the coupling mechanism was to reach under the trailer to grasp the latch by hand, and at the same time try to hold the safety in the release position. The elongated bar is pivoted in the center so it can be folded to a convenient length for drivers to carry with them as a personal item for use with whatever rig they may be assigned to drive.
摘要翻译： 一种解锁工具，用于将拖车从拖车的半挂车卡车装置中分离出来，其中包括在一端具有手抓握的可折叠细长杆和在相对工作端的组合安全释放臂和解锁钩。 安全释放臂与杆的工作端成直角地延伸，并且在一个方向上从杆延伸，而解锁钩从杆向相反方向向外延伸并从工作端向后退一短距离。 当解锁钩接合将拖车的主销锁定到拖拉机的联接闩锁时，安全释放臂延伸到解锁钩的前方足够远，以抵靠安全释放机构，该安全释放机构可以通过以下方式移动到安全释放位置： 杆的部分旋转或扭转同时拉动杆以将联接闩锁拉到解锁位置。 拖车然后可以从拖拉机脱离。 以前的联锁机构的解锁方法是在拖车下方手动抓住闩锁，同时力求将安全放在释放位置。 细长的杆在中心枢转，因此它可以被折叠到一个方便的长度，以便驾驶者携带它们作为个人物品，用于任何可能被分配驾驶的钻机。

摘要： A shuttered adapter is described that includes a shuttered housing, a shutter sub-assembly frame contained within the housing, a pair of shutter doors hingedly secured to the shutter sub-assembly frame, and a door spring configured to push the shutter doors outward from the shutter sub-assembly frame and away from each other. In addition, a shuttered adapter is described that includes a housing and a spring-like shutter attached to the front of the center wall of the housing. The shutter has a pair a door flaps extending into the ports of the adapter at a rearward angle.
