摘要： An enclosure for a vehicle end opening formed between two side walls includes two bi-fold door assemblies each comprising inner and outer panels pivotally connected to one another and with the free edge of the outer panels in turn connected to a fixed pivot point adjacent the side of the end opening wherein, each inner panel may be folded outwardly 180.degree. about its pivoted connecting means and the thus folded assembly subsequently pivoted about its fixed pivot point 270.degree. into parallel relationship with the vehicle side wall. The pivotal connecting means joining each pair of inner and outer panels includes catch means serving to secure the assembly in both the closed position enclosing the vehicle end opening as well as in the stored position parallel with the vehicle side wall.

摘要： An enclosure for a vehicle end opening disposed between two side walls includes a pair of bi-fold door assemblies, each comprising inner and outer panels hingedly connected to one another with the outer edges of the innermost panel in turn hingedly connected to a hinge rod normally disposed adjacent the outer limits of the end opening. Intermediate lock means are included with each pair of door panels for selectively precluding relative displacement therebetween and when actuated allows of folding of each pair of door panels to provide a collapsed juxtaposed relationship following which the folded door assembly may be pivoted about the hinge rod 90.degree. or until parallel to the vehicle side walls. The hinge rod supporting each door assembly is in turn supported and guided by hanger and track means extending longitudinally of the vehicle whereby the folded and pivoted door assembly may be displaced in a sliding manner to a retracted or stored position within the interior of the vehicle sides, at which point locking means are actuated to retain the door assembly secured.
摘要翻译： 设置在两个侧壁之间的用于车辆端部开口的外壳包括一对双折门组件，每个双折门组件包括彼此铰接地连接的内板和外板，最内面板的外边缘依次铰链地连接到铰链杆 邻近端部开口的外部边界设置。 中间锁定装置包括在每对门板中，用于选择性地排除它们之间的相对位移，并且当被致动时允许折叠每对门板以提供折叠的并置关系，之后折叠的门组件可围绕铰链杆90°枢转 或直到平行于车辆侧壁。 支撑每个门组件的铰链杆又由支架和由车辆纵向延伸的履带装置支撑和引导，由此折叠和枢转的门组件可以以滑动方式移动到车辆侧面内部的缩回或存放位置 此时锁定装置被致动以保持门组件的固定。
