摘要： A universally articulable supporting sheath comprises an interconnected series of links, each having a convex spherical surface at one end, and a concave spherical surface at its opposite end. The concave and convex surfaces mate with one another to form the sheath. Special links having branch openings may be provided. Various forms of waterproofing seals are provided, including O-rings, axially compressed rings, flexible belts, and ridges on the spherical surfaces. The links can be fitted together by thermal expansion. However, an axially split link is also described, which comprises two parts which snap together. The split parts may be molded as a unit with an integral thin wall hinge. The bending characteristics and bending radius of a sheath can be modified by insertion of spacers between the links at selected locations, or by the insertion of pins into radial holes provided in the links. Spacers with tongues may be used to prevent rotation of the links about the sheath axis, while allowing unidirectional articulation. Projections on one of a pair of mating spherical surfaces can be engaged with holes, slots or recesses of rectangular or other shapes to produce various limits on articulation and rotation. A single link may be provided with several alternatively usable holes, recesses and the like. The outer surface of a link can be provided with an axial extension engageable with a surface of an adjoining link to prevent back bending, or to prevent bending altogether.
摘要翻译： 普遍关节的支撑护套包括互连的连接系列，每个连杆在一端具有凸形球形表面，在其相对端具有凹形球形表面。 凹凸表面彼此配合形成护套。 可以提供具有分支开口的特殊连接。 提供各种形式的防水密封件，包括O形圈，轴向压缩环，柔性带和球形表面上的脊。 连杆可以通过热膨胀装配在一起。 然而，还描述了轴向分离连杆，其包括两个部件，它们卡在一起。 分开的部件可以被模制成具有整体薄壁铰链的单元。 护套的弯曲特性和弯曲半径可以通过在选定位置处的连杆之间插入间隔件，或者通过将销插入设置在连杆中的径向孔中来改变。 可以使用具有舌头的间隔器来防止链节围绕护套轴线的旋转，同时允许单向铰接。 一对配对球面之一上的突起可以与矩形或其它形状的孔，槽或凹槽接合，以产生铰接和旋转的各种限制。 单个链节可以设置有多个可选择的可用孔，凹槽等。 连杆的外表面可以设置有可与邻接连杆的表面接合的轴向延伸部，以防止背部弯曲，或者完全防止弯曲。
