| 摘要 |
The object (10) has long linkages (11, 12), first short linkages (13, 14) and second short linkages (15, 16) articulated with respect to each other so as to allow the object to occupy annular and compact configurations. The linkages have upper sides and lower sides, when an axis defined by the object is oriented vertically. The first short linkages are connected to the long linkages at the level of the lower sides by a first hinge (21) and a second hinge. The second short linkages are articulated to each other at the level of the upper sides by a third hinge. |
