    Abstract: A portable collapsible wheel is provided with fabric-type material spoke elements extending between the hub and the rim for performing the spoke function. The fabric-type material bears the weight of the load supported by the wheel in suspension from the rim. The spoke elements are secured to the hub and the rim and means are provided for tensioning the spoke material. The fabric-type material spoke elements diverge from each other toward the hub for triangulation and stability. The spoke elements may be in the form of disks or shallow conical elements secured to the rim as by hooks, and may be collapsed and folded into a small space. For tensioning, telescoping hub elements are described by way of example. A variety of rim constructions are also provided including a collapsible rim or segmented rim of a plurality of articulated polygonal abutting rim segments flexibly joined in sequence. Segmented rim may be folded and compressed into a circular arch with peripheral tread which forms the wheel tread. The fabric-type material spoke elements may comprise foldable strips such as ropes lines, cords or cables extending between the hub and rim and compressing the rim segments under tension. A fully collapsible wheel is therefore provided. A compression type portable wheel with conical shell spoke elements is also described.

    Abstract translation: 便携式可折叠轮设置有在轮毂和轮辋之间延伸的织物型材料轮辐元件，用于执行辐条功能。 织物型材料承受由轮缘悬挂的轮支撑的载荷的重量。 轮辐元件被固定到轮毂上并且轮辋和设备用于张紧轮辐材料。 织物类型的材料辐条元件彼此分离，朝向轮毂，用于三角测量和稳定性。 轮辐元件可以是通过钩固定到轮辋的盘或浅锥形元件的形式，并且可以被折叠并折叠成小的空间。 为了张紧，以示例的方式描述了伸缩轮毂元件。 还提供了各种轮辋结构，其包括依次柔性地连接的多个铰接的多边形邻接边缘部分的可折叠边缘或分段边缘。 分段边缘可以折叠并压缩成具有形成轮胎胎面的外围胎面的圆形拱形。 织物型材料辐条元件可以包括可折叠的条，例如在轮毂和轮辋之间延伸的绳索，绳索或缆索，并且在张力下压缩边缘片段。 因此，提供完全可折叠的车轮。 还描述了具有锥形壳辐条元件的压缩型便携式轮。
