Abstract
A lamp cover structure for easy assembly having a top ring with radial support bars, a bottom ring, of which the perimeter is greater than that of the top ring, and a support frame connecting the top ring and the bottom ring. Ends of the support bars are folded inward to form clip hooks. Upper transversal arch bars of the support frame have concave clip grooves bent downward to engage the clip hooks. The bottom ring has inwardly inclined support bars engaged by the support frame to constrain movement of the support frame.
Claims6
A lamp cover structure for easy assembly comprising:
- a) a top ring having a plurality of radially extending support bars, outward end portions of the support bars bent upwardly forming clip hooks;
- b) a bottom ring having a plurality of inwardly inclined supports forming clip spaces;
- and,
- c) a plurality of support frames releasably interconnecting the top and bottom rings, each support frame having two spaced apart vertical arch bars with upper end portions, an upper transverse arch bar connecting the upper end portions of the vertical arch bars, the upper transverse arch bar having a curvature matching a curvature of the top ring and forming a clip groove configured to engage the clip hook of the radially extending support bar, each vertical arch bar having a bottom portion configured to releasably engage the inwardly inclined supports of the bottom ring, whereby engagement of the bottom end portions with the inclined supports and engagement of the clip grooves with the clip hooks forms a lamp cover frame with the top and bottom rings spaced apart.
