摘要： PURPOSE: To provide high rigidity by forming a quadrangular pyramid as a stable structure by eliminating looseness of the pin joining part by keeping a balance state of force by generating compressive force in a rib by a wire tensioned between the mutual respective apexes to form the quadrangular pyramid. CONSTITUTION: A structure is unfolded by push-expanding a space between a main slide hinge 11 and a synchronous slide hinge 14 by spring force of a coil spring 17. When the main slide hinge 11 comes near to a stopper 16, a wire 13 between mutual upper surface side connectors 3a, between mutual lower surface side connectors 3b and 3c and between the connector 3a existing on the upper surface side free end and the connector 3c existing on the lower surface side free end is tensioned. Looseness of the pin joining part is eliminated since this wire 13 presses a connector 3 to the four rib 12 side. High rigidity can be easily obtained by forming a loosenessless structure by tensioning the wire 13 between the respective quadrangular pyramid apexes.

摘要： PURPOSE: To provide high rigidity by forming a hexagonal pyramid as a stable structure by eliminating looseness of the pin joining part by keeping a balance state of force by generating compressive force in a rib by a wire tensioned between the mutual respective apexes to form the hexagonal pyramid. CONSTITUTION: A structure is unfolded by push-expanding a space between a main slide hinge 11 and a synchronous slide hinge 14 by spring force of a coil spring 17. When the main slide hinge 11 comes near to a stopper 16, a wire 13 between mutual lower surface side connectors 3a, between mutual under surface side connectors 3b and 3c and between the connector 3a existing on the upper surface side free end and the connector 3c existing on the lower surface side free end is tensioned. Looseness of the pin joining part is eliminated since this wire 13 presses a connector 3 to the six rib 12 side. High rigidity can be easily obtained by forming a loosenessless structure by tensioning the wire 13 between the respective hexagonal pyramid apexes.

摘要： PURPOSE: To improve rigidity of an assembly in an extension mast developed in a cosmic space or the like to be assembled by stretching wires between vertexes of tetrahedrons, and compressing ribs to provide a force balanced condition to the assembly. CONSTITUTION: Development of an extension mast is conducted by pressing a main slide hinge 13 and a synchronous slide hinge 15 to be enlarged from each other by a coil apring 17. As distance between hinges 13, 15 is enlarged, distance between a coupler 3a and the hinge 13 on a center rod 12 is increased, but distance between the coupler 3a and another coupler 3b is kept in a constant length by a diagonal member 2, while distance between the coupler 3b and the hinge 13 is kept by length of a rib 14, so a triangle comprising above three vertexes is enlarged, with an angle formed by the rib 14 and the center rod 12 increased. As a result, distance between the coupler 3b and a separate coupler 10 provided on another rib 14 is also increased, thereby a wire 11 is tensed to press the coupler 3 toward the rib 14.

摘要： PURPOSE: To obtain a truss structure which extends by its own power and has a high rigidity by forming a skeleton by coupling between neighboring arbors facing oppositely each other with a rib and a diagonal member urged in the extension direction. CONSTITUTION: A plurality of arbors 10 are so arranged that neighboring ones face reversely each other, ribs 12 other than the ribs 12 being free ends of a structure are coupled to connectors 3 of the neighboring arbors 10, further, the connectors 3 of the arbor 10 are mutually coupled with diagonal members 2 thereby forming a skeleton. And a wire 13 is tensed between connectors 3 of the neighboring arbors 10 in the same direction, between other ends of ribs 12 being the free ends of the structure, and between the other end of this rib 12 and the connector 3 of the arbor 10. Also, the rib 12 is exerted in the extension direction by the coil spring 17 and a synchronous beam 15. By doing this, a light truss structure extending by its own power and having a high rigidity can be obtained.

摘要： PURPOSE:To provide an expansion mechanism in which expansion torque has monotone increase with progess of expansion. CONSTITUTION:A first vertical plate 7 and a sec. vertical plate 8 are placed on a bending material having pin-connected one end at its either side of a pin connection point. A first horizontal plate 9 in which its one end is pin- connected to the first vertical plate 7 is pin-connected to a sec. horizontal plate 10 in which its one end is pin-connected to the sec. vertical plate 8 by means of a connecting pin 3c. A spiral spring 4 is mounted at its one end on the head of the connecting pin 3c and is mounted at its other end on the first horizontal plate 9. The first and the sec. horizontal plate are rotated around the connecting pin 3c. Thus, setting is made in such a way that the first horizontal plate 9 is generally in line with the sec. horizontal plate 10 in expanding the bending member.

摘要： PURPOSE:To decrease the number of hinges for expansion use, to improve the reliability of expansion and to reduce the weight by using frames constituting the reflecting mirror only around the reflecting mirror. CONSTITUTION:The structure is provided with a member 17 in which a tetrahedron being a unit structure has a tilt member 3 and a coupler 4 in common, plural tetrahedrons are coupled so that the direction of adjacent rods 6 is made opposite shown in hatching in figure. A cable net 18 fitted to the coupler 4 by a net mounting metallic fixture 2 on the rear side of the reflection mirror, a tie wire 19 coupling a conductive net 1 and the cable net 18, a conductive net 1 and a terminal reinforcement plate 20 adhered on the circumference of the cable net 18. Then the tetrahedron structure being the unit structure exists only the circumference of the reflection mirror. Thus, number of hinges is decreased, the reliability of expansion is increased and light weight is attained.
