  • Support rod and sheath for lampshade
    Patent number: 7086760
    Abstract: This invention relates to the improved support rod and the fixing sheath for the lampshade. The basic structure of the lampshade is composed of several upper and lower fixing sheaths, several support rods, a set of upper and lower trays and a shade body. The main characteristics of the design are that the support rods and the upper and lower fixing sheaths are clamped separately and the curved hooks of the upper and lower sheaths can be pre-hooked to the upper and lower trays and integrated with the outer shade, which is easy for assembling and disassembling without removing the outer shade. It is much easier and faster to pre-enclose the upper and lower fixing sheaths, the outer shade of the upper and lower trays, the separate clamping of the support rods leading to great saving in production cost in the fabrication and assembly of support rods and fixing sheaths.
