    • The invention relates to an item comprising a hoop structure and to the method of folding it, the item being foldable between a deployed configuration for use and a circular folded storage configuration, which finds a particular application in items of the tent or shelter type. The hoop structure comprises at least one loop and is secured to a flexible covering. Folding-assistance means are provided, comprising at least one element for grasping which is attached to a first source point of the loop, or of the covering along the loop, so that by pulling, the first source point can be brought toward a first target point of the loop, or of the covering along the loop, so as to allow at least two subloops to be formed by twisting the loop. The first target and source points meet the following combined conditions: a - the distance, measured along the loop, between the first source point and the first target point is greater than or equal to 2.π.R
      rupt , where R
      rupt is the limiting radius of curvature of the loop, b - when the loop is in a substantially non-planar form with at least one main major axis and at least one main minor axis, the {first source point; first target point} pair lies neither on the main major axis nor on the main minor axis, c - when the loop is in a substantially planar oblong shape, with at least one main major axis, the {first source point; first target point} pair does not lie on the main major axis.
    • 本发明涉及一种包括环形结构的物品及其折叠方法,该物品可在展开的使用配置和圆形折叠储藏结构之间折叠,这在帐篷或遮蔽物类型的项目中具有特定的应用。 环形结构包括至少一个环,并且固定到柔性覆盖物。 提供了折叠辅助装置,其包括至少一个用于抓握的元件,该元件附接到环的第一源点或沿着环的覆盖物,使得通过拉动,第一源点可以朝向第一目标 点,或沿着环的覆盖,以允许通过扭转环形成至少两个子环。 第一个目标点和源点满足以下组合条件:a - 沿着循环测量的第一个源点和第一个目标点之间的距离大于或等于2.p.Rrupt,其中Rrupt是限制半径 所述环的曲率b,当所述环处于具有至少一个主长轴和至少一个主短轴的基本非平面形式时,所述{第一源点; 第一个目标点}对既不在主主轴上也不在主短轴上,c - 当环处于基本上平面的长方形形状时,具有至少一个主长轴,{第一源点; 第一个目标点}对不在主轴上。
