REFLECTOR AND ITS ASSEMBLING DEVICE Russian patent published in 2002 - IPC

FIELD: collapsible reflectors. SUBSTANCE: reflector has central circular panel and side sector circular panels; each panel is cellular three-layer structure; central panel mounts alignment ring and set of jointing inserts concentrically disposed relative to alignment ring; side sector panels are connected to central panel and to each other by means of bracket posts and bases of the latter are installed in each cellular three-layer panel. Reflector assembling device has jig with double-curvature working surface; jig working surface is convex and coincides with working surface of mandrel for shaping side sector circular panels; guide is made in the form of bushing for displacement along base line of mandrel; hold-down pieces have frame mounted on central circular panel by means of set of jointing inserts and alignment ring as well as on bushing through adapter. EFFECT: enhanced precision of reflecting surface at minimal manufacturing cost. 2 cl, 9 dwg
