Claims
- 1. A deployable diagonal structure comprising:two opposite longitudinal members; and two diagonal members rotatably connected each other at a mid-span thereof, each having at least one end connected to one end of each of said two opposite longitudinal members, wherein each said diagonal member has one end connected to one end of each of said two opposite longitudinal members and has the other end connected to a slider through which each of said two opposite longitudinal members passes, and said deployable diagonal structure is stowed or deployed by sliding said slider in such a way that said two opposite longitudinal members approach or separate each other.
- 2. A deployable diagonal structure comprising:two opposite longitudinal members; and two diagonal members rotatably connected each other at a mid-span thereof, each having at least one end connected to one end of each of said two opposite longitudinal members, wherein one diagonal member has both ends connected to said two opposite longitudinal members respectively and has a folding/unfolding portion between the mid-span and one end thereof and the other diagonal member has one end connected to one of said two opposite longitudinal members and has the other end connected to a slider through which the other of said two opposite longitudinal members passes, and said deployable diagonal structure is stowed or deployed by folding or unfolding the folding/unfolding portion and sliding said slider in such a way that said two opposite longitudinal members approach or separate each other.
- 3. A deployable diagonal structure according to claim 2 whereinsaid folding and unfolding portion comprises a foldable and unfoldable rotating hinge including a revolving means which provides turning force to said two diagonal members in the deployed direction or in the converged direction.
- 4. A deployable diagonal structure comprising:two opposite longitudinal members; and two diagonal members rotatably connected each other at a mid-span thereof, each having at least one end connected to one end of each of said two opposite longitudinal members, wherein said deployable diagonal structure is stowed or deployed in such a way that said two opposite longitudinal members approach or separate each other, said two diagonal members are rotatably connected by a crossing rotary hinge including a revolving means which provides turning force to said two diagonal members in the deployed direction or in the converged direction, and said two diagonal members are connected rotatably as well as connected to allow one diagonal member to slide on the other diagonal member by a predetermined length.
