Abstract

A pendant lamp shade is invertable so that it can be used in two configurations: either an up light or a down light. There is no need to remove the lamp shade from the lamp. The lamp shade has a floating inner ring (e, fig 3), which is large enough to pass over a light bulb. Arrays of shading leaves (g) are attached to the inner ring at their narrow end and taper out to a larger fixed ring (h, fig 3). The larger fixed ring is attached to the lamp by arms (b, fig 3), which may be made from wire. Pull handles (f, k) may be provided to pull the inner ring up or down over the light bulb, thus selecting the up light or down light configurations.

Description

INVERTING PENDANT LAMP SHADE

This invention relates to a pendant light shade with the ability to invert its self from a down light to an up light and consequently back from an up light to a down light.

Light shades are well known light deflectors. Of the most basic types, "Up" lights are designed for deflecting the majority of light up towards the ceiling. "Down" lights are designed for deflecting the majority of light down towards the ground.

These light shades are generally fitted as either an "up" light or a "down" light. They do not transform between one and another without removing them from there fitments. There is no ability to instantly change the general direction of the light between the similar shades (as described above), therefore restricting the possible immediate uses of the light.

The Invention resembles a down light, which enables the Invention to be used when a good light source is required from above.

The Invention also resembles an up light, which enables the invention to be used when a subtle light is wanted.

An object of this invention allows the easy conversion between these two types of light without the need to remove the shade from its fitment.

Accordingly there is provided a pendant light shade comprising a wire frame with means for attachment to a standard bulb fitment, from this at least two wire arms to provide means of connecting to a shade assembly.

A provided shade assembly with the means to invert consists of a small inner ring, which is adequately large enough to pass over a standard light bulb. A larger outer ring is connected to the smaller inner ring by a number of shading leaves. The shade assembly is subsequently attached at the rim of the larger outer ring to the frame at the two or more points provided by the arms.

To provide means of inverting the shade, it is preferred such that a hole at the top of each arm accepts each end of a form of pull cord or line fed though them. Each end of the line is attached to the small inner ring subsequent to being thread through each hole thus to enable an upward pull on the inner ring of the attached shade on pull of the line.

A second form of pull cord or line is also to be provided attached at similar points on the inner ring of the shade, thus to enable a downward pull on the inner ring of the shade on pull of the line.

Preferably, the inventions shading leaves may be made of 500micron polypropylene, but they may instead be of a material with similar properties. Twelve shading leaves may be used, however more or less can be used instead.

The invention may incorporate handles fitted to the pull cord.

The invention may also incorporate plastic T connectors to connect the wire arms to the large wire ring.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Drawing 1: Figure 1 Illustrates in perspective the invertible pendant light shade in its up light state where the concentration of the light reflects up to the ceiling.

Figure 2 Illustrates in perspective the invertible pendant light shade in its down light state where the concentration of the light reflects down to the ground.

Drawing 2: Figures 3, 4 and S illustrate a top (figs), front (fig4) and side (figs) profile of the invertible pendant light shade in its up light configuration without its shading leaves for clarity.

Referring to Drawing 2, the invertible pendant light shade comprises of a wire frame, consisting of (a) a disc for means of attachment to a light fitment (not shown), attached to the disc (a) are two supporting arms (b).

Two holes in the form of loops (c) are attached to the top of each supporting arm.

In order to provide means of an upward pull required to invert the shade, a line (d) is feed through the two loops (c). The line (d) is tied to two points of an inner ring (e).

Thus a pulling action on handle (f) pulls the inner ring (e) up, inverting the shade to a down light as illustrated in Drawing 1 figure 2.

Referring Drawing 1, the inner ring (e) is threaded through two holes in each of twelve shading leaves (g). A larger outer ring (h) is threaded though another two holes located at the other end of the twelve shading leaves. The outer ring (h) is attached to the two arms (b) by means of two T - connectors (I).

When in the down light configuration (see Drawing 1 figure 2), in order to provide a downward pull on the inner ring (e) to invert the shade, a second line (j) is tied at similar points to that of line (d). Thus a pulling action on handle (k) inverts the shade into an up light (see Drawing I figure 1).

Claims

1. A pendant light shade comprising a static frame, consisting of arms and a large outer ring, a floating shade assembly, consisting a small inner ring and a number of shading leaves where the inner ring of the shade assembly is free to float up or down over the light bulb.

2. A pendant light shade as claimed in claim 1 wherein the shading leaves are made of a flexible material.

3. A pendant light shade as claimed in claim 1 and 2 wherein the frame includes at least two arms with means of attachment to a pendant lamp holder.

4. A pendant light shade as claimed in claim 3 wherein the shading leaves connect the larger outer to the smaller inner ring.

5. A pendant light shade as claimed in claim 4 wherein the shading leaves are connected to both the inner and outer ring in such a way to allow pivoting movement about the rings.

6. A pendant light shade as claimed in claim 5 wherein the shade assembly and the larger outer ring are attached to the ends of the arms claimed in claim 3 by that of a Tee connector.

7. A pendant light shade as claimed in any preceding claim where the small inner ring is provided with means of a line to pull the inner ring down over the bulb.

8. A pendant light shade as claimed in any preceding claim where the small inner ring is provided with means of a line to pull the inner ring up over the bulb.

9. A pendant light shade as claimed in any preceding claim where holes are provided at the top of the arms to accommodate the line as claimed in claim 8.

10. A pendant light shade substantially as described herein with reference to Figures of Drawings 1 and 2.
