    • The invention provides an extendible member which is configurable between a coiled form and an extended form. The extendible member comprises: a primary member comprising a sheet of material resiliently biased in a slit tube form, wherein the slit tube can be opened out at the slit to assume an open form in which it has a flattened cross section; at least one resilient secondary member having first and second connections to the primary member at respective different circumferential positions on the primary member, wherein in the extended form, the primary member is in its slit tube form and the resiliency of the secondary member causes at least part of the secondary member to displace towards the slit in the primary member to provide torsional and axial stiffness to the primary member, and wherein in the coiled form, the primary member is in its open form and the secondary member conforms to the flattened cross section of the primary member so that primary and secondary member can be co-coiled. Corresponding methods are also provided.
    • 本发明提供了一种可延伸构件,其可在盘绕形式和延伸形式之间配置。 可延伸构件包括:主构件,其包括以狭缝管形式弹性偏压的材料片,其中所述狭缝管可以在所述狭缝处打开以呈现其具有扁平横截面的开放形式; 至少一个弹性次级构件,在主构件上的相应不同圆周位置处具有与主构件的第一和第二连接,其中,在延伸形式中,主构件处于其狭缝管形式,并且次构件的弹性至少使得 次要构件的一部分朝向主构件中的狭缝移位以向主构件提供扭转和轴向刚度,并且其中,在螺旋形式中,主构件处于其开放形式,次构件符合扁平横截面 的主要构件,使得主和次构件可以共同卷绕。 还提供了相应的方法。
