DETAILED DESCRIPTION OF THE INVENTION

(11) In all the figures of the drawing, sub-features and integral parts that correspond to one another bear the same reference symbol in each case.

(12) Referring now to the figures of the drawings in detail and first, particularly, to FIGS. 1 and 2 thereof, there is shown a high-hat light fixture 1 disposed or formed in a ceiling 2 and having a light bulb socket 3 holding a base 4′ of a light bulb 4. A user 5 is holding a light bulb removing and/or replacing device 6, hereinafter it shall be called a bulb extractor device 6. The bulb extractor device 6 has an extension pole 7 and a bulb removal/replacement head 8. The extension pole 7 is cylindrical in shape and can be a single-piece pole or a telescopic pole depending on the height requirements needed for accessing the light bulb 4.

(13) FIGS. 2 and 3 show a first embodiment of the bulb extractor device 6 with a shortened version of the extension pole 7 as the pole length cannot fit into the page limitation. FIG. 3 shows an exploded view of the bulb extractor device 6 with special attention to the bulb removal/replacement head 8. The bulb removal/replacement head 8 is formed of three main components, including an extractor head 9, a bulb attachment head 10 and a double-sided adhesive ring 11. The extension pole 7 has a first threaded end 15 which engages with or into a first threaded end 16 of the bulb attachment head 10. The first threaded end 16 although shown to be cylindrical in shape may be any shape that is capable of bearing the threading for receiving and securing to the extension pole 7. A first side 18 of the double-sided adhesive ring 11 attaches to a second, flat and circular end 17 of the bulb attachment head 10 with an adhesive fit (e.g. the double-sided adhesive ring 11 has an adhesive layer on both of its sides 18, 19). A second side 19 of the double-sided adhesive ring 11 attaches to a bottom or first side 20 of the extractor head 9. In this manner the double-sided adhesive ring 11 attaches and holds the extractor head 9 to the bulb attachment head 10 by an adhesive connection.

(14) By configuring the bulb extractor device 6 with the bulb attachment head 10, the double-sided adhesive ring 11 and the attached extractor head 9, the bulb extractor device 6 is configured for replacing a broken light bulb 4 residing in the high-hat light fixture 1.

(15) FIGS. 4-7 show different views and embodiments of the extractor head 9.

(16) FIG. 4 is a perspective view of a first embodiment of the extractor head 9 having a bulb extractor 25 surrounded by a guide 26. The guide 26 is cylindrically shaped and configured for nestling directly in the high hat-light fixture 1 with little play (e.g. the guide 26 has almost the same dimensions as an opening to the high-hat light fixture). More specifically a diameter D of the guide 26 is within ¼-1 inch, ideally ½ inch, of a diameter d of the high-hat light fixture 1. Because of the little play between the circumference of the guide 26 and the walls of the high-hat light fixture 1, a self-centering of the extractor head 9 in the high-hat light fixture 1 is accomplished.

(17) The bulb extractor 25 is formed of four (4) blades 27 disposed at 90 intervals (e.g. 3, 5, 6 or 8 blades are also feasible). The four blades 27 meet at a center point 28 which defines a digging point or tip 28 for digging into a base of the broken light bulb 4. Each blade 27 is formed with a curved shape or arching taper 29 as best shown in FIGS. 4 and 7. Ideally, the curved shape or arching taper 29 of each of the blades 27 allows the bulb extractor 25 to fit into various sized bulbs by further extending into the base of the broken light bulb 4. Two of the blades 27 form a half oval and the bulb extractor 25 is formed from two intersecting half ovals. Furthermore, in a modified embodiment of the extractor head 9, the blades 27 have a teething or roughing 40 which provide a greater frictional engagement with the base of the light bulb 4, see FIG. 7. Please note the in FIG. 7 the teething or roughening 40 is exaggerated.

(18) The blades 27 can be formed from various materials which each have their own advantages and disadvantages. More specifically, the blades 27 can be formed completely from a hard plastic. In this manner the digging tip 28 can penetrate deeply into the base 4′ of the broken light bulb 4. A rotational force and a pushing force is applied to the extension pole 7 and the broken light bulb 4 is loosened in the light socket 3 and removed. However, due to the use of a hard plastic, frictional forces are reduced and slippage between the bulb extractor 25 and the broken light bulb 4 may occur upon turning of the extension pole 7.

(19) In a second alternative embodiment, the blades 27 can be formed from a more elastic material. In this manner, the digging tip 28 can be squished into the base 4′ of the broken light bulb 4 and has a more frictional engagement with the base 4′ of the broken light bulb 4 for removing the broken light bulb 4. Furthermore, such an elastic tip 28 can deform to fit into various sized bases of the broken light bulb 4.

(20) In a third embodiment, a bottom base 31 of the blades 27 is formed of a harder plastic and an upper section 32 is formed of a more flexible plastic or rubber, see FIG. 6. In this configuration, the hard plastic provides a stronger overall structure of the extractor head 9 and at the same time provides an elastic tip 28 for digging into the base 4′ of the broken light bulb 4 and creating a greater frictional engagement with the light bulb 4.

(21) In all three embodiments the guide 26 forms a pocket 34 into which broken glass can be collected and centers the tip 28 for engaging into the base 4′ of any sized light bulb 4 that fits in the respective high-hat light fixture 1. The guide 26 has a height H that ideally extends approximately half way up a height h of the blades 27 which provides adequate centering ability and a deep enough pocket 34 for collecting sizable glass pieces that may break off. In addition, the guide 26 can be made of either a hard plastic or a flexible material as with the blades 27.

(22) FIGS. 6 and 7 show a further refinement of the extractor head 9. The bottom side 20 of the extractor head 9 is configured with a threading 33 and can engage directly with the threading 15 of the extension pole 7 and therefore the bulb attachment head 10 and the double-side adhesive ring 11 are not necessary. As shown in FIGS. 6 and 7, the threading 33 is formed in a cylindrical body 35 which extends into the pocket 34 and around which the blades 27 are attached to and extend from.

(23) By configuring the extractor device 6 with only the bulb attachment head 10 and the adhesive ring 11 (e.g. without the extractor head 9), the bulb extractor device 6 is configured for replacing an unbroken bulb 4 in the high-hat light fixture 1. As shown in FIGS. 8-10, the bulb attachment head 10 is ideally circular in shape and has a diameter being approximately equal to that of a front face of a light bulb 4 to be removed, albeit slightly smaller. The exposed adhesive side 19 of the double-sided adhesive ring 11 is raised and placed in front of a front face of the light bulb 4 to be replaced. Then the adhesive side 19 is pressed on the front face of the light bulb 4. A rotational force is now applied to the extension pole 7 and the light bulb 4 is removed from the light socket 3. The extension pole 7 is lowered and old light bulb is pulled off of the double-sided adhesive ring 11. A new light bulb is attached to the double-sided adhesive ring 11 and the extension pole 7 is raised so that the new light bulb 4 can be screwed into the light socket 3. At this point a quick snap or pull of the extension pole 7 releases the adhesive bond between the double-sided adhesive ring 11 and new light bulb secured in the light socket 3.

(24) In essence, the bulb extractor device 6 is configured for replacing undamaged burned out light bulbs and damaged light bulbs. The bulb extractor device 6 is ideally formed to remove broken light bulbs fitted in high-hat light fixtures 1 as it automatically centers the bulb extractor in the base of the damaged light bulb.
