12 Claims. (Cl. 240-108) This invention relates to a lighting and lamp fixture in general. More specifically, the invention is directed to the construction and arrangement of a decorative lamp shade.

It is one of the objects of the present invention to provide a low cost multiple piece lamp shade constructed from parts that are elficiently and easily fabricated.

it is another object of the present invention to provide a lamp shade having decorative open areasfor the passage of limited light rays to enhance the appearance of the shade over the conventional solid lamp shade.

Another object of this invention is to provide a decorative lamp that includes constructional means embodying light diffusion members to allow light passage through the decorative areas of the shade but in non-glare intensities.

Itis another object of this invention to provide light diffusion members that are constructed from translucent heat resistant materials to Withstand the heat generated by the lamp of the shade. As a further object the invention contemplates the use of aheat resistance dye, enamel or lacquer with which to cover and dye the heat resistant material whereby the decorative areas of the lamp shade emit colored light. I

A further object of the present invention is to construct a lamp shade of the character noted by the assembly of at least two light shields of segmental nature which are joined in such a fashion that they are separated or spaced apart for the greater portion of their lengths to receive interposed connecting elements that include decorative perforations, and which elements also stabilize or join the segmental spaced shields into a completed lamp housing or light enclosing shade.

The construction further provides connecting elements for the lamp shields that incorporate guide means for colored or tinted and interchangeable inserts which are releasably retained in superimposed relation with respect to the decorative areas presented by the elements intermediate the spaced portions of the lamp shade shields.

All other objects and advantages of the present invention shall hereinafter appear in the following detailed description having reference to the accompanying drawings forming a part of this specification.

Figure 2 is a similar side elevational view of the lamp shade partially disassembled and with certain parts thereof broken away and in section;

Figure 3 is an end elevational view of one of the segmental shield portions of the lamp shade as seen from the right in Figure 2 and including certain connecting parts;

Figure 4 is a plan view of the perforated decorative strip whichtis interposed between the spaced shields of the lamp shade and which also forms the connecting element for joining the shields and for holding colored inserts;

Figure 5 is an edge view of the decorative connecting strip illustrated in Figure 4;

Figure 6 is a fragmentary side view of the lamp shade illustrating the assembled arrangement of the parts and the decorative portion of the lamp shade;

Figure 7 is a similar view as that shown in Figure 6 but including the insertion of the colored or tinted insert;

Figure '8 is a plan view of one of the colored inserts of the lamp shade; and

. Figure 9, 10 and 11 are successive transverse cross sectional views taken substantially along the lines 9-9, Ill--10 and 1111 in Figure 7.

The lamp shade of the present invention may be used as a portion of numerous types of fixtures or desk lamps and other analogous devices of this character. As shown in Figure l, the lamp shade is connected with a wall fixture. In the preferred construction of shade illustrated in Figure l, the assembly comprises at least one pair of segmental shields 1 and 2 having decorative means such as 3 interposed on each side of the lamp at degrees with respect to each other. The heel end of the lamp is finished off with an enclosure member comprising the cap 4- which normally carries the lamp socket construction, internal wires, etc. As illustrated in Figure l, a hollow support 5 is connected with the cap 4 and this unit is pivotally carried upon one end of the support 6 which is arranged to swivel at 7 with respect to the mounting base 8 that is suitably connected to a wall such as 9.

As best illustrated in Figures 2 and 3, each of the segmental shields 1 and 2 are or identical construction so that reference to the constructional parts and arrangement of one will be identical to the other. 'The shield 1 comprises the outwardly flared and segmental shade 10 having spaced longitudinal edges such as 11 terminating in spaced relation to the matched shield edge 11 of the shield 2. This spaced arrangement extends substantially the length of the shade structure and terminates at 12 as shown in Figure 2. The heel end of each of the segmental shields is provided with a semi-circular annular rim 13 which provides heel edges 14 that abut one another as best shown in Figure 2. By placing the two shields together with the heel edges in abutting relation and with the semi-annular portions aligned as shown in Figure 2, each of the shield sections are joined or connected by retaining clips 15 which overlap the seams formed by the edges 14 and these retaining clips are suitably welded or otherwise secured to the semi-circular rims 13. This positions the two lamp shields as shown in Figure 2. The cap 4 is assembled upon the completed rim 13-13 overlying the same and further stabilizing this assembled portion of the lamp shade structure. The cap 4, when assembled, also places the bracket ts in a given relation with respect to the lamp enclosure to suitably support a conventional lamp receiving socket as is conventional practice.

it should-also be noted that the cap 4 is provided with projections such as l5 that enter suitably formed bayonet slots 16 that are formed in the rim halves 13 of each shield l. and 2. In this manner the cap 4 may be removed and again assembled during the construction of the lamp or during the servicing of the parts thereof if this becomes necessary.

The edges 11 of each of the shields together with the edges 12 thereof are reenforced by means of bands 17 which follow the contour of the opening 18 formed between the respective lamp shades or shields at each side of the lamp structure. These bands reenforce the relatively thin metal edges of the two shields and also prevent damage or crushing of the members during assembly and after assembly. In addition, each of the edges 11 are provided with suitable cars such as 19 and 20 associated with the shields l and 2. It should also be noted that the retaining clips are each provided with an offset portion such as 21 to create a pocket at each side of the completed shade and in alignment with the openings 18 between the shields. These pockets are best illustrated in Figures 6 and 7.

The assembly of the shade is completed by means of strips 22 such as shown in Figures 4 and 5. These strips form an integral portion of the decorative means 3 illustrated in Figures 1, 6 and 7. Each of the strips 22 is angled or produced in tapered fashion to fit into the opening 18 which is also of similar contour as best noted in Figures 1 and 2. Tne strips 22 are provided with decorative perforations 23 that extend substantially the length of the strips and between a pair of guides forming channels 24- and 25, which channels extend along the opposite edges of the strips 22. Each of the strips 22 also has a pair of slots 26 and 27 which are adapted for the reception of the cars 19 and 20 at the adjacent shield edges.

in completing the assembly of the lamp shade per se, one of the strips 22 is connected adjacent each opening 18 to the spaced or separated shield portions of the lamp as best shown in Figure 6. The strip has the end 28 adapted for insertion into the pocket 21 of the retaining clip 15 and the end 29 of the strip is arranged to receive the cars 19 and 2% which are normally maintained in upright position with respect to the edges 11 of each of the shields during the assembly of the shade. Both of these cars 19 and 22') are then bent over as shown in Figure 9 to lock the decorative strip 22 into position across the opening 18 between the lamp shields. By means of the stabilization of the end 23 of the strip 22 in the pocket 21 and by means of the general rigidity of the strip which is superimposed inwardly of the lamp and behind the band 17, together with the securing of the ears 1% and to the strips, forms a rigid lamp assembly. Thus the insert 22 comprises the decorative member and also the stabilizing and connecting means for the shade parts primarily including the segmental shields 1 and 2. In this connection, it should also be noted that the channels 24 and 25 form reenforcing means for the strip 22 creating longitudinal stiffness at the joining areas of the lamp shields and that these channels are also maintained against the rear portion of the edges 11-11 of the shields l and 2 and along the areas defined by the bands 1717.

As seen in Figures 7 and 8, a colored insert 30 provides the light diffusing means which is interchangeably insertable into the guide means and channels of the strip 22. This insert 30 may be of a transparent nature if desired, but preferably it is semi-transparent and translucent. Furthermore, the insert 3!) is constructed from a heat resistant material which may be similar to glass or mica or some suitable plastic. Preferably the insert illustrated at 33 in Figures 7 and 8 is made of fibre glass and comprises a relatively stiff sheet of material giving the same sullicien'; body to maintain its shape while in use. in addition, this insert may be colored or tinted by suitable dyeing or coating of one or both sides of this unit. The tinting material or dye as well as any surface coloring fluid is of a character wherein this material is heat resistant so that it does not change in color nor does this material liake off of the insert or insert material. The present construction contemplates the use of a colored enamel which is applied to the strip ard baked on under high temperature conditions. Such a strip has proven durable and can withstand the normal high temperatures which exist in a lamp shade by reason of the considerable heatgenerated by the lamp.

As shown in Figure 8, the strip comprises the tapered arrangement proportioned to fit the insert and the guides thereon. in addition, the left hand portion of the strip shown at 31 is formed to fit in with the contour of the 4 end 2% of the strip 22. It should also be noted that the strip is provided with lateral projections 32 and 33.

in the construction of the assembled lamp and as best seen in Figures 7 and 9, it should be noted that the ears i9 and 20 are maintained in the general plane of the channels 24 and 25 of the insert 22. Furthermore, each of the cars 19 and 2t) are spaced away from the adjacent channel ends to thereby provide the slotted areas as shown at 34 and in Figure 6. By inserting a relatively stiff and thin insert 39 into the channels 24 and 25, the end of the insert also enters into the pocket 21 of the retaining clip while the forward or outer edge portion 36 of the strip snaps into place behind the cars 19 and 20 with the edges 37 and 3% of the strip abutting such ears. The shoulders 39 and it) engage the edges 41 and 42 of the channels, thus holding the entire insert in place over the perforations Z3 and against accidental removal during the use of the shade. in this connection, the pointed end 43 does provide a finger tip portion that is accessible to lift the forward end 31 of the insert out of its retained location between the cars 19 and 2t) and channels 24 and 2:3 to remove the insert from the guide portion 22. Thus the insert 3t"; may be interchangeably used in the lamp to change the color combinations of the difiused light.

The foregoing explanation has been directed to the preferred embodiment of the invention as illustrated in the drawings. it is obvious that other changes may be made in the exact construction of the individual parts or the assembly thereof without departing from the fundamental concept of this invention. in this connection, it is deemed that two or more individual segmental shield sections may be employed with a like additional number of inserts or decorative means between such multiple shields. All modifications shall, however, be governed by the breadth and scope of the appended claims directed to this invention.
