To provide a deployable device.SOLUTION: The invention relates to a spreadable device (10) including: a supporting structure (11); a mandrel (12) able to move in rotation with respect to the supporting structure (11) around a first axis Z; a membrane (13) able to shift from a rolled-up state rolled up around the mandrel along the first axis Z to a spread state spread along a second axis X substantially perpendicular to the first axis Z. The device comprises two fittings (14) secured to the mandrel (12) at their center, each one of which is arranged on both sides of the membrane (13) and comprising first stubs (15) on their periphery (16) of the two fittings (14), and one casing (17) extending between the two fittings (14). The casing (17) comprises second stubs (18) having a shape complementing a shape of the first stubs (15). The casing (17) is able to shift from a rolled-up state at least partially enveloping the membrane (13) in the rolled-up state to a spread state at least partially superposed on the membrane (13) in the spread state.SELECTED DRAWING: Figure 1
【課題】展開可能な装置を提供する。【解決手段】本発明は、支持構造(11)と、支持構造(11)に対して第1の軸Zの回りに回転移動可能な心棒(12)と、第1の軸Zに沿う心棒の回りに巻き取られた巻き取り状態から、第1の軸Zにほぼ垂直な第2の軸Xに沿って展開された展開状態に移行可能な膜(13)とを含む展開可能な装置(10)に関する。本発明によれば、膜(13)の両側に1個ずつ配置された2個の継手(14)の周縁(16)に第1のスタブ(15)を含んでいて中央で心棒(12)に固定された2個の継手(14)と、2個の継手(14)の間に延在する1個の包材(17)とを含み、包材(17)が第1のスタブ(15)の形状を補完する形状の第2のスタブ(18)を含み、包材(17)が、巻き取り状態にある膜(13)を少なくとも部分的に包む巻き取り状態から、展開状態にある膜(13)に少なくとも部分的に重ね合わされた展開状態に移行可能である。【選択図】図1
