摘要： Latch and lock structure for a door wherein the latch includes a bolt and is pivotally mounted upon the door for movement around an axis substantially perpendicular to the plane of the door when it is in its closed position. The latch has an end portion with a recess opening radially of said axis. A bracket is secured to the door for engagement by the latch when it is in the latch position. An L-shaped lever is pivotally secured to the bracket and has an abutment on one leg thereof which is receivable into said recess when said latch is in the latched position. Actuating means engages the other leg of said L-shaped lever for pivoting same and thereby moving said abutment out of said recess. Resilient means yieldably urges said abutment means into the locked position, said actuating means limiting the amount of said urging.

摘要： A dock seal assembly for an opening in a wall, said seal assembly having a resiliently flexible head seal supported by upright, parallel track means mounted upon the wall adjacent the sides of said opening near the upper end thereof. Spring-biased annular means is supported upon the wall for rotation about a horizontal axis near the upper end of said opening and is connected to the head seal by sheet means which covers said upper end of the opening when the head seal is lowered. The sheet means also serves to raise the head seal when it is released from an anchored, lowered position.

摘要： A lock structure for an upwardly acting door of a truck van wherein a latch bolt and a manually engageable actuating handle are pivotally mounted upon a door for movement about a common axis which is substantially perpendicular to the plane of the door when it is in the closed position. The latch bolt has an elongated arcuate hook portion adapted to extend below the lower edge of the door for engagement with a catch mounted on the truck bed. The actuating handle is pivotally mounted on the mounting plate which is fixedly secured to the external side of the door. The latch bolt is pivotally supported on a release pin which extends through the door and is accessible solely from the inside of the door. The inner end of the release pin has a release lever coupled thereto which, when actuated, pulls the latch pin towards the interior of the truck van whereby the pin is disconnected from the latch bolt. The door can then be opened from the interior of the truck van and the lock structure, except for the latch bolt, remains fixed to the door.
摘要翻译： 一种用于货车向上作用的门的锁定结构，其中闩锁螺栓和可手动接合的致动手柄枢转地安装在门上，用于围绕公共轴线运动，该公共轴线在其处于闭合状态时基本上垂直于门的平面 位置。 闩锁螺栓具有细长的弓形钩部分，其适于在门的下边缘下方延伸，用于与安装在卡车车厢上的卡扣接合。 致动手柄枢转地安装在安装板上，该固定板固定地固定到门的外侧。 闩锁螺栓枢转地支撑在释放销上，释放销延伸穿过门，并且可以仅从门的内部访问。 释放销的内端具有联接到其上的释放杆，当被致动时，释放杆将闩锁销拉向卡车厢的内部，由此销与闩锁螺栓断开。 然后可以从卡车货车的内部打开门，除了闩锁螺栓之外，锁定结构保持固定在门上。
