Apparatus forming three dimensional sign display character

摘要: A relatively thin thermoplastic sheet material, vacuum molded to form a sign letter base including hollow wall members and light-fixture supports upstanding from single-thickness horizontal bottom member. The inverted forms mold itself for receiving flexible plastic foam inserted suitable height disposed within the vertical walls fixture providing compressible elasticity in predetermined locations enabling cooperative interaction of same with retainer used secure display face gas filled lighting tube structures proper location onto base. rigid polyester resin is cast as ring encircling walls, located supported by stabilize support nature Rotatable positioning platforms journaled frictional interference light supports, receive display-tube grippers adjustably positioned above collinear array breakoff spheroids integrally shouldered one other. expansively displace action tube-forced insertion recoil around holding engagement aided plurality resilient tine sectors deflecting longitudinally buoy interference.
