    • A one-piece molded plastic vehicular enclosure for children is disclosed. The vehicular enclosure, which can either be a car or truck configuration, has a length substantially greater than its width and height. The enclosure includes opposing top and bottom surfaces and opposing side surfaces inner connecting the top and bottom surfaces. The enclosure further includes opposing front and rear surfaces extending between the top and bottom surfaces and side surfaces. The rear surface includes a rear entry opening for ingress and egress of children into and out of the enclosure. The rear entry opening is defined by a cylindrical extension projecting from the rear surface. The rear entry opening has a height and width substantially equal to the distance between the top and bottom surfaces to facilitate ingress and egress into the enclosure by children. Preferably, the rear entry opening is sufficiently large to permit two children to pass one another during ingress and egress relative to the enclosure.
    • 公开了一种用于儿童的单件模制塑料车辆外壳。 可以是汽车或卡车配置的车辆外壳的长度显着大于其宽度和高度。 外壳包括相对的顶表面和底表面以及连接顶表面和底表面的相对侧表面。 外壳还包括在顶表面和底表面和侧表面之间延伸的相对的前表面和后表面。 后表面包括用于进入和离开外壳的入口和出口的后入口。 后入口由从后表面突出的圆柱形延伸部限定。 后入口具有基本上等于顶表面和底表面之间的距离的高度和宽度,以便于儿童进入外壳。 优选地,后入口开口足够大以允许两个孩子相对于外壳进入和离开时彼此通过。
