Abstract
An improved structure foldable assembly-type lamp shade comprised of a top ring at the uppermost end of the lamp shade, a bottom ring of larger circumference than the top ring, and frame members propped between the top ring and the bottom ring. The bottom ring has fixing mounts consecutively disposed at the frame member locations that provide for the assembly and positioning of the frame members, with the fixing mounts at the support member installation locations having different type connection sections based on the respective type of fixing mount arrangement utilized. When packaged, since the frame members can be first folded down and whorled into a flat state such that the frame members and the top ring are stacked on the bottom ring, the lamp shade of the present invention occupies the smallest physical assembly area to facilitate ease of assembly and, furthermore, the resulting minimized storage area effectively reduces shipping costs.

The said top ring 1 has support rods 11 extending from the center to the circumference and, furthermore, the support rods 11 are aligned with the frame members 3 at the circumferential edge of the top ring 1 and an inclosing space is formed by upward bending that provides for situating the top ends of the frame members 3 against the bottom edge of the inclosing space 111.
The said bottom ring 2 has fixing mounts 21 consecutively disposed at the frame member 3 locations that provide for positioning the bottom posts of the frame members 3.
The said frame member 3 have their top ends against the bottom edge of the inclosing space 111, with the bottom posts of the frame members 3 secured in fixing mounts 21, 22, 23, 24, and 25 of differing respective arrangements that each constitute different type connection sections that engage and retain the frame members 3 between the top ring 1 and the bottom ring 2.
The method by which the frame members 3 are connected to the bottom ring 2 is based on the bottom ring 2 fixing mounts 21, 22, 23, 24, and 25 of differing arrangements and the respective insertion approach of the frame member 3 bottom posts into the varying structures so constituted such that the frame members 3 are engaged and retained between the top ring 1 and the bottom ring 2, wherein:
In FIG. l, the drawing of the first mounting embodiment of the invention herein, the said bottom ring 2 fixing mount 21 consists of a laterally extending tab 212 having an insertion hole 211; the bottom end of each said frame member 3 having a matching bend that enables it to be inserted into the fixing mount 21 insertion hole 211 and, furthermore, thrust locked in the tab 212 by a penetration tenon 3 3 on it.
In FIG. 2, the drawing of the second mounting embodiment of the invention herein, the said bottom ring 2 fixing mount 22 consists of an annular structure that is round and tubular shaped and, furthermore, with an insertion hole 221 through its center; the bottom end of each frame member 3 having a matching bend that enables its penetration tenon 34 to be inserted within the insertion hole 221.
In FIG. 3, the drawing of the third mounting embodiment of the invention herein, the said bottom ring 2 fixing mount 23 has its center portion upwardly shaped into convexity, leaving a space between it and the bottom ring 2 that forms a holding slot 231 onto which each frame member 3 is yoked; the bottom end of each frame member 3 having a matching configuration that enables insertion through the holding slot 231, and disposed around the convex end of the fixing mount 23 is a sleeve ring 35 and, furthermore, the encircled attachment of the sleeve ring 35 positions each frame member 3 onto the bottom ring 2.
In FIG. 4, the drawing of the fourth mounting embodiment of the invention herein, the said bottom ring 2 fixing mount 24 consists of an annular structure that is semicircular in shape and, furthermore, the annular surface of which is slanted inward; the bottom end of each frame member 3 having a matching bend that is perpendicular to the bottom ring 2 and, furthermore, enables insertion of a penetration tenon 36 on it into the bottom ring 2 fixing mount 24;
furthermore, after the penetration tenons 36 of the frame members 3 are inserted into the fixing mount 24, the frame member 3 top ends are against the bottom edge of the support rod 11 inclosing spaces 111 to limit the movement of the frame members 3.
In FIG. 5, the drawing of the fifth mounting embodiment of the invention herein, each said frame member 3 has convexly formed at their bottom-end center sections a contact friction extremity 32 situated against the inner side of the bottom ring 2; the corresponding bottom ring 2 fixing mount 25 is banded around the contact friction extremities 32 of the frame members 3 and the outer circumference of the bottom ring 2, the bottom ring 2 and the frame members 3 fastened into a unitary physical entity such that the frame members 3 are positioned onto the bottom ring 2.
In FIG. 6, the drawing of the sixth mounting embodiment of the invention herein, the bottom ends of the said frame members 3 are directly punch formed into a flat fastening sections 31 and, furthermore, a through-hole 311 is formed in the center of each fastening section 31 to provide for ensleeving onto the bottom ring 2; formed at an appropriate location in the said bottom ring 2 is an opening end S
and, furthermore, the opening end S provides for the insertion and ensleeving of the frame member 3 fastening sections 31, and pressure flattened by punch forming at the two sides of the ensleeved frame member 3 fastening sections 31 are stop nubs 26 that limit the movement of the frame members 3; following which, the opening end S of the bottom ring 2 is welded together.
Referring to FIG. 7, the drawing of the invention herein when folded, when packaging is desired, the frame members 3 must be first folded down and whorled into a flat state such that the frame members 3 and the top ring 1 are stacked on the bottom ring 2; as such, when packaged in cartons, the lamp shade of the present invention occupies the smallest physical assembly space to facilitate ease of assembly and, furthermore, the resulting minimized storage area effectively reduces shipping costs.
Referring to FIG. 8, after the assembly of the said lamp shade framework is completed, the exterior periphery of the top ring 1 and the bottom ring 2 are covered with a fabric material lamp shade 4, wherein the exterior fabric surface layer 41 of the said lamp shade 4 is first tightly fitted onto the outer periphery of the frame members 3; the interior fabric surface layer 42 is then placed along the inner sides of the frame members 3 and, furthermore, an adhesive fastening tape 43 is respectively applied over the appropriate portions of the interior and the exterior fabric surface layers 41 and 42, the frame members 3 are enveloped within such that the frame members 3 remain unexposed due to the ensconcing structural arrangement constituted by the interior and the exterior fabric surface layers 41 and 42, while also effectively achieving an attractive appearance; in addition, when the framework is folded, the lamp shade 4 collapses along with it to achieve a reduction in material storage area and thereby effectively lowers shipping costs.
