[0019] Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, a collapsible lampshade assembly 10 having a shade 30, a first frame 11 for maintaining a shape of the shade 30 and for connecting to a harp of a light fixture; a second frame 41 for maintaining the shape of the shade 30; a first plurality of pins 22 adjacent to a first edge of the shade 30 for preventing the shade 30 from being separated for the first frame 11 by placing the first frame 11 below the first plurality of pins 22; and a second plurality of pins 23 adjacent to a second edge of the shade 30 for preventing the shade 30 from being separated from the second frame 41 by placing the second frame 41 on the second plurality of pins 23 is generally shown.

[0020] In FIG. 1, the assembled collapsible lampshade assembly 10 is shown. FIG. 2 shows another embodiment of the assembled collapsible lampshade assembly. As shown in FIGS. 1 and 2, the shapes of the open bases 32 and 33 could be oval and rectangular.

[0021] As shown in FIG. 3, the first frame 11 defines an outer frame 12, a fitter 14 at the center of the outer frame 12 for sitting on a reducer of the harp of a light fixture, and a plurality of legs 13 radiating from the fitter 14 to the outer frame 12. The outer frame 12 has a circular shape. However, it should be appreciated that the outer frame 12 could have other shapes such as, but not limited to, an oval, square, rectangle, pentagon, octagon, or hexagon shape. The first frame 11 is made out of a metal material. However, it should be appreciated that the first frame 11 could be made out of other materials such as, but not limited to natural polymeric materials which are strong enough to hang the shade 30 on the outer frame 12 with the second frame 41 or a rigid polyvinyl chloride. The fitter 14 is disposed at the center of the outer frame 12 for the collapsible lampshade assembly 10 to sit on a reducer of the harp of a light fixture. Accordingly, the center of the fitter 14 has a hole for the reducer disposed at the top of the harp to fit into the hole. The size of the hole could be various depending on the diameter of commercial reducers. The position of the fitter 14 could have the same height with the height of the outer frame 12 when the lamp shade assembly 10 is properly installed. However, it should be appreciated that the height of the fitter 14 could be lower or higher than the height of the outer frame 12 when the lamp shade assembly 10 is installed. The plurality of legs 13 are elongated members to connect the fitter 14 and the outer frame 12. However, it should be appreciated that the shape of the leg 13 could be different to connect the fitter 14 and the outer frame 12. In this embodiment, the first frame 11 has three legs 13. However, it should be appreciated that the number of legs could be different, but not limited to, four, five, six, or eight.

[0022] The second frame 41 has a circular shape. However, it should be appreciated that the second frame 41 could have other shapes such as, but not limited to, an oval, square, rectangle, pentagon, octagon, or hexagon shape. The shape of the second frame 41 is generally the same as the shape of the outer frame 12. However, it should be appreciated that the shape of the second frame 41 could be different from the shape of the outer frame 12. The size of the second frame 41 is also generally the same as the size of the outer frame 12. However, the size of the second frame 41 may be different from the size of the outer frame 12. Moreover, even if the shape of the second frame 41 is same with the shape of the outer frame 12, the size of the second frame 41 could be different from the size of the outer frame 12. For example, the diameter of the circular-shape second frame 41 could be longer than the diameter of the circular-shape outer frame 12. The second frame 41 is made out of a metal material. However, it should be appreciated that the second frame 41 could be made out of other materials such as, but not limited to natural polymeric materials or a rigid polyvinyl chloride.

[0023] The shade 30 is disposed between the first frame 11 and the second frame 41 to soften or direct the lamp light. The lamp light is disposed in the shade 30. The shade 30 has a circular cylindrical shape having two parallel open ends 32 and 33 connected by a curved surface 34. However, it should be appreciated that the shade 30 could have other shapes such as, but not limited to, an oval cylindrical, cubical, rectangular parallelepiped, pentagon parallelepiped, octagon parallelepiped, or hexagon parallelepiped shape. One open base 32 has the same shape and size with the shape and size of the outer frame 12. The other open base 33 has the same shape and size with the shape and size of the second frame 41. The shade 30 is collapsible when the shade is separated from the first and second frames 11 and 41. The collapsed shade 30 and the first and second frames 11 and 41 are suitable for shipping and maintenance because they reduce the size of the shipping or storing package. The reduced size of the package is more sustainable from the force outside more than shipping or storing a lamp shade while maintaining the basic structure of the lamp shade.

[0024] As shown FIG. 4, the shade 30 defines a lining 36 and a cover 35 attached on the lining 36 for ornamenting the external appearance of the collapsible lampshade 10. The lining 36 is pliable enough to be bent but hard enough to form the shape of the collapsible lampshade 10. The pliable lining 36 makes the shade 30 collapsible in a parallel way to the ground if the collapsible lampshade is in the set-up position. Thus, the shape of the open bases 32 and 33 would change to the shape fitting in to the shipping package. For example, the circle shape of the open bases 32 and 33 could be oval. The rectangle shape of the open bases 32 and 33 could be a diamond shape. If the shape of the outer frame 12 and the second frame 41 is, but not limited to, a square, rectangle, pentagon, octagon, or hexagon shape, the lining 36 could be made out of, but not limited to, glass, acrylic glass, rigid polyvinyl chloride or a metal material, which is not a pliable material. The lining 36 is generally made out of a translucent material to soften the lamp light. However, the lining 36 could be made out of a transparent or opaque material. The lining 36 is hard enough to form a basic lampshade structure if the first and second frames 12 and 41 are installed in the shade 30. The cover 35 is attached on the outside 34 of the lining 36 to have an effect to disperse the lamp light in the shade 30. The cover 35 is made out of, but not limited to, a Linen fabric, silk, wool, or cotton. The cover 35 may also have a decoration for ornamenting the external appearance of the collapsible lampshade.

[0025] The first plurality of pins 22 are attached on the inside of the lining 36. If the first frame 11 is put in the shade and properly installed in a perpendicular angle to the curved surface 34 of the shade 30, the first plurality of pins 22 prevent the first frame 11 from being separated from the shade 30. It is because the size of the first open end 32 is the same as the size of the first frame 11. Similarly, the second plurality of pins 23 are attached on the inside of the lining 32. If the second frame 41 is put in the shade and properly installed in a perpendicular angle to the curved surface 34 of the shade 30, the first plurality of pins 22 prevent the first frame 11 from being separated from the shade 30. It is because the size of the second open end 33 is the same as the size of the second frame 41. The plurality of pins 22 and 23 have a shape of cylinder. However, it should be appreciated that the plurality of pins 22 and 23 could have other shapes such as, but not limited to, a hexahedron.

[0026] The shade trim tape 37 having an adhesive surface is taped on the outside of the cover 35 and the inside of the lining 36. The shade trim tape encloses a pin 22 to fasten the pin 22 adjacent to the edge of the shade 30. Since the pin 22 is fastened adjacent to the edge of the shade 30, the outer frame 12 is prevented from moving out of the shade 30. This mechanism applies to the other plurality of pins 22 and 23 adjacent to upper edge and lower edge of the shade 30.

[0027] As shown in FIGS. 5-6, the edges of the shade 30 are taped by upper and lower shade trim tapes 37. Each shade trim tape 37 is attached on the cover 35 and the lining 36 covering the upper and lower edges of the shade 30. A portion of the shade trim tape 37 is cut into a plurality of tabs at a right angle to the edge of the shade trim tape 37. Each shade trim tape 37 is attached on the lining 36 such that the tabs covers the plurality of pins 22 and 23 and are wrapped around the plurality of pins 22 and 23 to hold them in place. Since the plurality of pins 22 and 23 are disposed between the inside of the lining 36 and each shade trim tape 37, the plurality of pins 22 and 23 themselves are invisible. The shade trim tape portions between the tabs are attached inside of the lining 36 without contacting the plurality of pins 22 and 23.

[0028] As shown in FIG. 5, a first plurality of pins 22 may be adjacent to a first edge of the shade 30 for preventing the shade 30 from being separated from the first frame 11 due to the gravity force of the shade 30 by placing the first frame 11 below the first plurality of pins 22, and a second plurality of pins 23 disposed on a second edge of the shade 30 from preventing the second frame 41 from being separated from the shade 30 due to the gravity force of the second frame 41 by placing the second frame 41 on the second plurality of pins 23. The plurality of pins 22 and 23 may have about 1 inch (2.54 cm) length and 0.1 inch (0.25 cm) diameter. However, it should be appreciated that the size of the plurality of pins 22 and 23 could be different sizes. In particular, if the shape of the outer frame 12 and the second frame 41 is a round shape, the length of the plurality of pins 22 and 23 should be short enough not to distort the round shape. The plurality of pins 22 and 23 may be a curved shape. If the shape of the outer frame 12 and the second frame 41 is a square, rectangle, pentagon, octagon, or hexagon shape, the length of the plurality of pins 22 and 23 may be equal or less than the length of the side of the square, rectangle, pentagon, octagon, or hexagon shape, respectively. The length of the plurality of pins 22 and 23 may be equal to one side of the outer frame 12 and the second frame 41. If so, the cut shade trim tape 37 has equal or longer than the length of the plurality of pins 22 and 23 to cover and hide the plurality of pins 22 and 23. The plurality of pins 22 and 23 may be made out of a metal material. However, it should be appreciated that the plurality of pins 22 and 23 could be made out of other materials such as, but not limited to natural polymeric materials or a rigid polyvinyl chloride.

[0029] As shown FIG. 7, peripheral tape bands 38 may encircle the upper and lower edges of the shade 30 and hide the outer and second frames 12 and 41 and the shade trim tape 37 when the frames are installed in the shade 30.

[0030] As shown in FIG, 8, extra portions 39 and 40 of the cover 35 may be used in place of the shade trim tape 37. In this embodiment, the cover 35 is wider than the width of the lining 36. In particular, both edges of the lining 36 are covered by the cover 35, The extra portions 39 and 40 of the cover 35 may be adhesively attached on the inside of the lining 36. The extra portions of the cover 35 are cut at right angles to form tabs 39 and portions 40. The plurality of pins 22 and 23 are adhesively attached on the inside of the lining 36 by the tabs 39. Since the plurality of pins 22 and 23 are disposed between the inside of the lining 36 and covered by the tabs 39, the plurality of pins 22 and 23 themselves are invisible. The portions 40 of the cover 35 are attached inside of the lining 36. A peripheral tape bands 38 may be attached over the edges of the shade 30 as in the first embodiment.
