The present invention is directed to an interchangeable adapter for changing light bulbs and more particularly to an interchangeable adapter for changing LED (light-emitting diode) light bulbs.
Light-bulb changers are known in the art and allow a user to change a light bulb without using a step ladder or touching a hot bulb. A typical changer comprises a grabber for grabbing a light bulb, attached to a pole for allowing a user to reach the light bulb with the grabber. The grabber includes flexible fingers for engaging the light bulb and allowing the user to unscrew the light bulb. A changer can be sold with multiple grabbers for different sizes and shapes of light bulbs, each of them removably attachable to the pole with a threaded connection. The grabbers are designed for use with roughly spherical incandescent light bulbs, spotlight bulbs, and compact fluorescent light (CFL) bulbs.
In an unrelated development, LED light bulbs are increasingly popular, at least in part because of federal regulations. A typical LED light bulb, which can be designed to fit into the same socket as a traditional incandescent light bulb, is shown in
However, LED light bulbs are typically shaped differently from conventional incandescent, halogen, or compact fluorescent light bulbs. For example, the bulb 100 of
It is therefore an object of the invention to provide a light-bulb changer for changing LED light bulbs.
To achieve the above and other objects, the present invention is directed to an adapter for changing LED light bulbs. The adapter can have a threaded fitting for attachment to the pole of an existing light-bulb changer. The adapter has a body, preferably formed of a rigid material such as a rigid plastic. The body has multiple teeth to engage the spaces between the cooling fins of the LED light bulb. The light bulb can then be unscrewed from its socket and lowered using the pole and the adapter. A new light bulb can be placed on the teeth, raised, and screwed into the socket.
The adapter can be designed for each type of LED light bulb and for the pole to which it is to be attached. The adapter has the correct number of teeth, and the correct length of each tooth, to engage the light bulb for removal. The teeth typically face directly forward, parallel to the axis of the adapter, to allow easy insertion of the teeth into the spaces and easy removal once the light bulb has been lowered from its socket. The adapter is also designed to attach to the pole; as a result, the adapter can have a conical, hemispherical, or similar shape.
Multiple such adapters can be sold together as a kit for changing multiple types of light bulbs. An adapter can be sold with a pole, with screw adapters for mounting on different types of poles, or separately.
The present invention also provides a head piece for an adapter for changing a light bulb that includes a base plate that has opposite first and second sides, and a perimeter defined between first and second sides, and the base plate defines a platform at the first side. A plurality of teeth extend from the platform of the first side of the base plate away from the second side. The plurality of teeth are spaced and arranged on the platform to engage the light bulb. An engagement member extends from the second surface of the base plate away from the first side for engaging a holder of the adapter.
The present invention further provides an interchangeable adapter for changing a light bulb that includes a holder that has a mounting end and an interface end opposite the mounting end, and a first engagement member disposed inside of the holder. At least one head piece that is separate from the holder is releasably coupled thereto at the interface end of the holder. The head piece has a base plate with opposite first and second sides, and the first side defines a platform. A plurality of teeth extend from the platform of the first side of the base plate. The plurality of teeth are spaced and arranged on the platform to engage the light bulb. A second engagement member extends from the second side of the base plate for engaging the first engagement member of the holder.
The present invention yet further provides a method for changing a light bulb that includes the steps of providing a holder of an adapter for changing the light bulb, the holder having a mounting end and an interface end opposite the mounting end, and a first engagement member disposed inside of the holder; providing a plurality of head pieces, each of the head pieces having, a base plate with opposite first and second sides, the first side defining a platform, a plurality of teeth extending from the platform of the first side of the base plate, the plurality of teeth being spaced and arranged on the platform to engage the light bulb, and a second engagement member extending from the second side of the base plate for releasably engaging the first engagement member of the holder; selecting one of the plurality of head pieces; and coupling the selected one of the plurality of head pieces with the interface end of the holder by releasably coupling the first and second engagement members.
The present invention may still further provide a headpiece for an interchangeable adapter for changing a light bulb that includes a base plate with opposite first and second sides and that defines a platform at the first side. A primary gripping member extends from the platform of the first side of the base plate away from the second side. The primary gripping member is positioned substantially centrally with respect to the platform to engage the light bulb. A secondary gripping member extends from the platform of the first side of the base plate away from the second side. The secondary gripping member surrounds the primary gripping member and is configured to grip the light bulb. An engagement member extends from the second side of the base plate away from the first side for engaging a holder of the adapter. In a preferred embodiment, the primary gripping member is a suction cup.

Preferred embodiments of the invention will be described in detail with reference to the drawings, in which like reference numerals refer to like elements or steps throughout.
The adapter 200 has a body 202. At one end of the body 202 is a mount 204, such as a threaded mount, designed to mount the adapter 200 onto the pole 210 of a light-bulb changer, which can be a light-bulb changer now on the market or yet to be introduced. At the other end are teeth 206 for engaging with the light bulb in a manner to be explained below. The teeth 206 extend parallel to the axis B of the adapter 200 for easy engagement and disengagement with the light bulb. Because the end with the mount 204 and the end with the teeth 206 typically have different diameters, the body 202 has a shape, such as a cone or a hemisphere, although any other suitable shape can be chosen.
The adapter 200 can be made in any suitable way, such as by molding or by machining, and out of any suitable material, such as rigid plastic. It is contemplated that the body 202 will have an empty space 208 to reduce both the weight of the adapter 200 and the amount of material used; however, the body 202 could be solid if so desired.
Each adapter 200a, 200b, 200c has a body 202a, 202b, 202c having curved sides. Ribs 402a, 402b, 402c are formed between the body 202a, 202b, 202c and the mount 204a, 204b, 204c. Otherwise, the adapters 200a, 200b, 200c can be formed like the adapter 200 of
As seen in
The engagement member 540 opposite the teeth 530 may be a stem that is slightly shorter and smaller than the elongated stem 514 of the holder 502, thereby allowing the elongated stem 514 of the holder 502 to receive the stem 540 of the head piece 506a. In a preferred embodiment, the stems 514 and 540 releasably engage one another in a telescoping friction fit. Other releasable engagement mechanisms may use used, such as a snap or latch engagement. Although the stems 514 and 540 are shown has having a generally square cross-sectional shape, the stems 514 and 540 may have other cross-sectional shapes, such as circular, as long as one of the stems 514 or 540 can receive the other stem 514 or 540 in a telescoping manner.
The primary gripping member 1230 is preferably a suction cup having an open face 1234 facing away from the platform 1228. The suction cup 1230 may be positioned substantially centrally with respect to the platform 1228 to engage the light bulb. The suction cup 1230 is preferably formed of rubber to apply sufficient suction when pushed against the light bulb for gripping the light bulb. The suction cup 1230 may be formed of any material that is capable of applying suction to the light bulb. The suction cup 1230 may be releasably coupled to the platform 1228 by an attachment member 1236, as seen in
The secondary gripping member 1232 is preferably a channel 1250 that includes opposing first and second grip arms 1252 and 1254 for further gripping of the light bulb. The channel 1250 may be spaced from the perimeter of the base plate 1220 and substantially surround the suction cup 1230. The channel 1250 is preferably formed of rubber to provide a friction grip between its arms 1252 and 1254 and the light bulb. The channel 1250 may be formed of any material that is capable of sufficiently gripping the light bulb. The channel 1250 has a substantially circular shape and substantially circles the suction cup 1230. The opposing first and second grip arms 1252 and 1254 may flare outwardly slightly to improve the grip on the light bulb, as seen in
When using the adapter 500 with the head piece 506f of the sixth embodiment mounted thereon for changing a light bulb, the suction cup 1230 is first applied against the light bulb. The adapter is then moved or pushed toward the light bulb thereby compressing the suction cup 1230 against the light bulb to establish a suction grip of the light bulb. The adapter is pushed against the light bulb until the channel 1250 also grips the light bulb via a friction grip with the channel's grip arms 1252 and 1254. Once both the suction cup 1230 and the channel 1250 have both gripped the light bulb, the light bulb can be removed and changed. To release the light bulb from the adapter, the holder 502 is twisted and pulled with enough force to break the suction of the suction 1230 and friction grip of channel 1250.
To use the interchangeable adapter 500, the user selects one of the head pieces 506a, 506b, 506c, 506d, 506e, or 506f in accordance with the size and type of light bulb to be changed. The user can then assemble the selected head piece 506 on the holder 502 by placing the selected head piece 506 on the holder's interface end 510 and coupling the engagement members 514 and 540. The engagement members 514 and 540 are configured to releasably couple, such as by a friction fit, thereby allowing the user to grasp and remove the selected head piece 506 from the holder 502 and replace it with another head piece as desired.
While preferred embodiments and variations thereof have been set forth above, those skilled in the art who have reviewed the present disclosure will readily appreciate that other embodiments can be realized within the scope of the invention. For example, the holder, head pieces, the teeth, suction cup, and channel can have any proportions that are compatible with the light bulb to be changed, and the adapter can have any compatible number of teeth. The diameter and width of the teeth may be changed in accordance with the size and type of light bulb. Additionally, the number of teeth may be selected based on the light bulb being grasped, including just one tooth. Similarly, the diameter of the suction cup and channel may be changed in accordance with the size and type of light bulb. Also, the invention can be used with an LED light bulb or any other similar device. Moreover, any shape of any component (such as the body 200, 200a, 200b, 200c, and holder 502) can be used as long as the adapter still works. Therefore, the present invention should be construed as limited only by the appended claims.
