It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art.
1. Field of the Invention
The present invention relates generally to the field of vacuum tools and more specifically relates to vacuum tools used to change light bulbs.
2. Description of the Related Art
The incandescent light bulb, makes light by heating a metal filament wire to a high temperature until it glows. The hot filament is typically protected from air by a glass bulb that is evacuated and filled with inert gas. In a halogen lamp, a chemical process returns metal to the filament, extending its life. The light bulb is supplied with electrical current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket which supports the bulb mechanically and connects the current supply to the bulb's electrical terminals.
Incandescent bulbs are produced in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment and have a low manufacturing cost and work equally well on either alternating current or direct current. As a result, the incandescent lamp is widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. These lights fail after repeated use and need to be changed.
Unfortunately, many consumers experience difficulty changing light bulbs in hard to reach areas such as in ceiling light fixtures. These bulbs can be very high up, and may therefore be virtually inaccessible to consumers without the use of stools or ladders. Further, standing on stools, ladders, and other objects may prove dangerous, and may put users at risk of falling and incurring injuries. This can be particularly risky and difficult for elderly or less agile individuals. Additionally, light bulbs may break when being grasped to be changed creating risk of injury for such individuals. A safe and efficient means for changing expired light bulbs is desirable.
Various attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. Nos. 7,234,743; 7,334,503; 5,218,889; 7,631,579; 5,148,723; and 2,637,587. This prior art is representative of light bulb changing tools. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.
Ideally, a vacuum tool used to change light bulbs should be user-friendly, and yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable bulb changer attachment system to quickly and easily change light bulbs located in ceiling light fixtures and to avoid the above-mentioned problems.
In view of the foregoing disadvantages inherent in the known light bulb changing tools art, the present invention provides a novel bulb changer attachment system. The general purpose of the present invention, which will be described subsequently in greater detail is to provide a vacuum tool used to couple to and change light bulbs located in ceiling light fixtures quickly and easily.
The present invention, bulb changer attachment system, as disclosed herein, preferably comprises: a conical suction light bulb receiver having a distal end and a proximal end; a base having a top portion and a bottom portion; an adapter; and a vacuum hose attachment providing vacuum communication with at least one vacuum. The conical suction light bulb receiver is connected to the top portion of the base (or integral with in alternate embodiments.) Further, the conical suction light bulb receiver preferably comprises soft, (pliable) flexible rubber thereby being attachable to varying sizes of the outer periphery of the light bulb. The soft, flexible rubber provides a conforming seal with the light bulb when the vacuum communication is commenced.
The light bulb (being changed) is couplably-received by the conical suction light bulb receiver such that an apex of the light bulb is suction-contacted by the proximal end of the conical suction light bulb receiver and an outer periphery is suction-contacted via the distal end of the conical suction light bulb receiver. The distal end of the conical suction light bulb receiver comprises a diameter greater than the proximal end of the conical suction light bulb, making the shape conical. A distance between the distal end and the proximal end of the conical suction light bulb is variable since the conical suction light bulb receiver comprises the soft, flexible rubber, enabling varying sizes of the light bulb to be changed. Further, the conical suction light bulb receiver is removeably-coupleable to the light bulb enabling a user to remotely access the light bulb from a hard-to-reach surface and remove the light bulb via a negative pressure placed on the light bulb.
The base preferably comprises hard/rigid plastic, may be reversible and is cylindrically-shaped. Further, the base may comprise a rotatable impeller. If present, the rotatable impeller comprises at least one bladed fan. The rotatable impeller is driven by the negative pressure of the vacuum in a clockwise direction to create a turning torque on the light bulb thereby causing the light bulb to be tightened into a socket. The rotatable impeller when reversed is driven by the negative pressure of the vacuum in a counter-clockwise direction to create a turning torque on the light bulb thereby causing the light bulb to be loosened from a socket. The impeller may be housed in other portions of the present invention and may be operated (forward and reversed) via other means.
In certain embodiments an adapter is rotatable such that the impeller movement maybe operated in forward or reverse. In alternate embodiments the base is initially oriented in a first orientation and is reversible via removing the base and inserting the base at 180 degrees in a second orientation relative to the first orientation. The first orientation and the second orientation both comprise a lengthwise relationship between the conical suction light bulb receiver and the adapter. The bottom portion of the base is connectable to the vacuum hose attachment via the adapter. The vacuum hose attachment allows the conical suction light bulb receiver to be in vacuum communication with at least one vacuum through the base and the adapter, with the vacuum being remotely placed.
A kit is embodied herein for the bulb changer attachment system comprising: at least one base; at least one conical suction light bulb receiver; a vacuum hose attachment optionally having at least one impeller; and a set of user instructions.
In accordance with the embodiments of the present invention a preferred method of use is disclosed herein comprising: inserting a light bulb into a conical suction light bulb receiver; attaching a vacuum to a vacuum hose attachment; activating the vacuum to provide a vacuum communication and resulting suction (negative pressure) in a vacuum hose attachment for temporary securement of the light bulb; and turning the light bulb (installing or removing.)
The present invention holds significant improvements and serves as a bulb changer attachment system. For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein.
