    • A fastener for releasably securing a first substrate to an apertured second substrate includes a base member and a locking member mounted for rotation relative to the base member. The locking member is rotatable between an insertion position for insertion of the base member and locking member through the aperture formed in the second substrate and a locking position for releasably securing the first and second substrates together. A resilient member is provided to bias the locking member toward the base member when the resilient member is compressed. The locking member includes at least one protrusion and the base member includes at least one detent. The detent and protrusion are configured to releasably engage each other in the insertion position of the locking member and disengage from each other upon rotation of the locking member toward the locking position.
    • 用于可释放地将第一基底固定到有孔第二基底的紧固件包括基部构件和安装成相对于基底构件旋转的锁定构件。 锁定构件可以在用于插入基座构件和锁定构件的插入位置之间通过形成在第二衬底中的孔的位置和用于将第一和第二衬底可释放地固定在一起的锁定位置之间转动。 弹性构件被设置成当弹性构件被压缩时将锁定构件朝向基座构件偏置。 所述锁定构件包括至少一个突起,并且所述基座构件包括至少一个棘爪。 棘爪和突起构造成在锁定构件的插入位置中可释放地彼此接合,并且在锁定构件朝向锁定位置旋转时彼此分离。

    • An overhead guard assembly for use on an materials handling vehicle provides the operator with protection against falling objects. The assembly includes first and second frame members supported by the vehicle and positioned on either side of the operator, and a plate member placed between and secured to the frame members over the head of the operator. A plurality of openings are formed in the plate member to provide the operator a clear view upwardly through said overhead guard. The openings in said overhead guard are arranged in rows and a plurality of strengthening ribs are placed in the plate member between the rows and extend from one frame member to the other. The strengthening ribs are formed by reverse bending the plate member to provide a rib surface orientated at an angle of approximately 50.degree. with respect to the horizontal to provide minimum visual obstruction to the operator.
    • 用于材料处理车辆的顶棚防护组件为操作者提供防坠落物体的保护。 组件包括由车辆支撑并定位在操作者的任一侧上的第一和第二框架构件,以及放置在操作者头部之间并固定到框架构件的板构件。 在板构件中形成多个开口,以向操作者提供通过所述顶棚防护件的向上的清晰视图。 所述顶棚防护罩中的开口被排列成一列,并且多个加强肋被放置在板构件之间,并且从一个框架件延伸到另一个。 加强肋通过反向弯曲板构件形成,以提供相对于水平面定向为大约50°的角度的肋表面,以向操作者提供最小的视觉障碍。
