发明名称 Knock-down lamp shade
摘要 A lampshade which is shipped and/or stored in a knock-down condition can be readily erected without tools into a shade which is as structurally sound as if manufactured in preassembled condition. The shade is formed of two ring members, one having a spider member affixed thereto; a plurality of rib members; a plurality of clamping members having means for releasably securing clamping member to a rib member and a ring member, and hence the latter to each other; and a lamp shade frame cover adapted to be placed about the other members in the assembled condition.
