Abstract:
A lampshade having an assembled state and a collapsed state includes a first ring, a second ring spaced apart from the first ring when the lampshade is in the assembled state, and a first fabric covering interconnecting the first and second rings. A third ring is located adjacent the first ring when the lampshade is in the assembled state. A plurality of supports are connected between the second ring and the third ring. Each support has a first end portion movably connected to the second ring and a second end portion movably connected to the third ring. The supports hold the second and third rings spaced from each other. The supports urge the third ring into engagement with the first ring thereby to hold the first ring spaced apart from the second ring.
