Title:
GUIDE MECHANISM IN EXPANSION STRUCTURE
Document Type and Number:
Japanese Patent JPH06156400
Kind Code:
A
Abstract:

PURPOSE: To stably expand a truss body by installing guide rollers on the cube of the truss body and by providing a supporting plate with a guide for guiding the guide rollers to restrain the movement of the cube until at the final stage of expansion.

CONSTITUTION: An expansion structure has a cube 3 comprising a long and narrow material for forming a truss body by expansion in the unidimensional direction. In expanding the expansion structure, for example, traveling rails 11 upwardly folded are forwardly turned and expanded at the front of a housing 5. The cube 3 at its frontmost part is pulled along the traveling rails 11 trough traveling rollers 10. Guide rollers 15 installed on tire back part of the long and narrow material are guided along an upper side guide plate 17a interposed on a supporting plate 16 for the traveling rails 11. Thus, the front movement of the traveling rollers 15 is restrained until at the final stage of the expansion of the cube 13. The rest part of the cube 3 is, therefore, prevented from being pulled out of the housing 5 for flowing.
