KNOC~ ~ LAMP ~HADE
File No. ~7-70~
TECHNICAL FIELD
This invention relates to an improved lamp shade. More particularly, this invention relates to an improved knock-down lamp shade whlch can be shipped and stored in a substantially flat condition and erected without the use of tools.
BACKGROUND ART
Commonly, lamp shades are manufactured in a formed or erected condition, prior to being shipped. These lamp shades require con-siderable and inordinate storage and shipping space compared to the weight of the materials. This is particularly evident in the case of cylindrical or box-shaped shades. While tapered or frustoconical shaped shades may be nested or stacked, the nest or stack of shades still requires an inordinate amount of space. Moreover, shades having decorative covers with an irregular surface, such as with trim strips at the upper or lower or both edges of the shade cover, may be damaged and the strips torn during the nesting and unnesting operations.
Modern merchandising practices often require items, such as lamp shades, to be shipped and stored in individual packages for con-venient delivery to the customer. Lamp shades which are preassembled or manufactured in the erected conditions cannot be inexpensively stored or shipped in individual containers.
Numerous attempts have been made to construct collapsible or knock-down shades that can be stored and shipped compactly and then assembled by the consumer. However, many of the shades previously proposed depend upon an outer, relatively ri~id material for the struct~ral in~egrity of the erected shade and thus limit the shape and decorative features of the shade.

Examples of shades of this
-2-l 1~06~7 type are disclosed in U.S. Patents 3,142,446; 3,764,801; 3,787,676 and ~,055,760. Attempts have also been made to provide a collapsible lamp shade in which the erecting operation requires adhesive strips.
Examples of such attempts are found in U.S. Patents 3,142,~46 and 4,055,760. However, the necessity of the consumer having to align parts of the shade and apply adhesive or adhesive strips in the erecting operation detracts from the merchandisability of the item.
For these and other reasons, the knock-down shades prior to the present invention have not attained commercial acceptability.

Referring to the drawings, the numeral 10 indicates generally a lamp shade in accordance with the present invention. Lamp shade 10 is frustoconical in shape, as shown, or can be of other shape such as cylindrical, rectangular, or ovular.
As shown in Fig. 2, lamp shade 10 has an upper ring member 12 and a lower ring member 14. A spider member, generally in-dicated by numeral 16, comprises a central member 18 and a plur-ality of arms 20. Central member 18 may be ring-shaped and is adapted to be supported ~y a lamp, for example by the harp o~ a lamp.
Arms 20 are preferably spaced from each other and radially positioned, and each is affixed at one end to central member 18 and at the other end to upper ring member 12. Arms 20 of spider member 16 and upper ring 12 can be formed o~ wire and the arms 20 affixed to central member 18 and to upper ring member 12 by brazing, soldering or other method or by fasteners. Spider member 16 and upper ring ~ 1606~7 member 12 can be formed ~o lie in a single plane, as shown, c arms 20 can be bent so that central member 18 lies in a diff~ at plane from ring member 12. ~or ease of packaging and material economy, it is preferred to have members 16 and 12 lie in the same plane.
Lamp shade 10 further includes rib members 22 which are positionable between ring members 12 and 14 when the latter are in an axially spaced condition, as shown in Figs. 2 and 3. Rib members 22 as well as lower ring member 14 can be formed of wire. It is preferable to have at least four rib members 22 to provide a sturdy lamp shade when erected and larger numbers of rib members can be used, particularly when the ring members are of other shape, such as oval, rectangular or square, to form a lamp shade of non-cylindrical or non-frustoconical shape.
Lamp shade 10 further includes clamping members 24, each clamping member having means for receiving and releasably securing the clamping member to one of the rib members 22 and for receiving and releasably securing the clamping member to of the ring members 12 or 14.

For this purpose, lamp shade 10 includes a lamp shade frame cover 40 which is adapted to be stored in a substantially flat condition. Cover 40 may be of any suitable material, for example fabric, as shown, and may have one or more decorative bands 42 positioned about the periphery of cover 40. Shade cover 40 can also include an elastic band 44 secured to an upper margin thereof and also a second elastic band 46 secured to the lower margin of cover 40.
Upon arrival at the location the shade is to be used, normally at the customer's location, shade 10 can be readily and easily erected without tools. Clamping members 24 are placed over the ends of rib members 22 and the latter inserted into U-shaped portions 26 of clamping members 24 as shown in Fig. 4. Rib members 22 with clamping members 24 releasably secured at each end thereof are positioned along side and between ring members 12 and 14 as best shown in Fig. 2. Each of clamping members 24 in turn is then releasably secured to the facing ring member by inserting the ring member into the portions 28 and 30 as indicated in Fig. 2, and compressing the rings axially until the ends of the ribs 22 abut the rings, as shown in Fig. 6. Upon completion of the inserting of the ring members into the portions 28 and 30 of clamping member 24 the components, except for the cover 40, are releasably assembled into a relatively rigid lamp shade frame which is structurally as sound as a pre-assembled frame. The final step in the erection 1 ~606~7 of the lamp shade 10 is to place the shade cover 40 over and about the thus formed frame as best shown in Fig. 3. Elastic bands 44 and 46 serve to maintain the cover 40 taut about the assembled frame.
