The present invention relates generally to battery-operated lights and more specifically to portable battery-operated lights.
Battery-operated flashlights have been available for decades. Work lights are another form of battery-operated lights that may include a base for standing the work light on its end or a hook to allow the work light to be hung from a structure. There exists a need in the art, however, to provide a light that is capable of being operated in a standing or hanging position that can also be activated, dimmed or deactivated in a simple manner.
Accordingly, the present invention provides an improved battery-operated beacon pendant light that can be operated in a standing or hanging position. The pendant light of the present invention includes a clear base portion that provides a stand for the beacon light, an upper housing portion that houses the electronics and LED lights and a hook assembly, that may be in the form of a carabineer that is coupled to a switch at the top of the upper housing to allow one hand operation of the beacon light. A battery compartment is provided in the center of the base portion to allow easy access to the battery for replacement.
According to one aspect of the invention, a battery-operated pendant light comprises a base housing having an outer wall forming a lens, an upper housing coupled to the base housing, a plurality of lights coupled to the upper housing to direct light from the plurality of lights into the base housing, a battery compartment coupled to the upper housing and extending into and centrally located within the base housing, with the battery compartment configured to retain at least one battery therein, and a rotatable electrical switch coupled to a top of the upper housing and a hook assembly coupled to the switch, wherein rotation of the hook assembly relative to the upper housing in a first direction moves the switch from an off position to an on position and wherein rotation of the hook assembly relative to the upper housing in a second direction opposite the first direction moves the switch from an on position to an off position, the rotatable switch being electrically coupled between the battery housing and the plurality of lights to thereby control illumination of the plurality of lights.
In another embodiment of the invention, a USB port is electrically coupled to the battery housing to provide a charging capability from the USB port.
In yet another embodiment, a USB cable is electrically coupled between the USB port and the battery compartment. The USB cable is removably nestable within a channel beneath a lip portion of the upper housing and at least partially circumferentially extends around the base housing when in a nested position.
In still another embodiment, the base housing is generally cylindrical in shape and comprises a plurality of feet integrally formed with and radially extending from the bottom of the base housing to support the battery-operated pendant light on a surface.
In another embodiment, the hook assembly comprises a carabineer that is pivotally coupled to a knob that is coupled to the switch to allow the hook assembly to pivot from an upright position to a lower position.
In yet another embodiment, rotating the base housing or the upper housing relative to the hook assembly in a first direction rotates the switch assembly from an on position to an off position and rotating the base housing or the upper housing relative to the hook assembly in a second direction rotates the switch assembly from an off position to an of position.
In yet another embodiment, the hook assembly comprises an upper hook portion coupled to an arcuate base portion. The arcuate base portion is pivotally coupled to the knob at opposite sides thereof and in a pivotal manner to allow the base portion and thus the hook portion to pivot relative to the knob at least 180 degrees.

These and other aspects of the present invention may be realized in an improved pendant light as shown and described in the following figures and related description.
When considered in connection with the following illustrative figures, a more complete understanding of the present invention may be derived by referring to the detailed description. In the figures, like reference numbers refer to like elements or acts throughout the figures. Various embodiments of the present invention are shown and described in reference to the numbered drawings.
It will be appreciated that the drawings are illustrative and not limiting of the scope of the invention, which is defined by the appended claims. The embodiments shown accomplish various aspects and objects of the invention. It is appreciated that it is not possible to clearly show each element and aspect of the invention in a single figure, and as such, multiple figures are presented to separately illustrate the various details of the invention in greater clarity. Similarly, not every embodiment need accomplish all advantages of the present invention. Elements and acts in the figures are illustrated for simplicity and have not necessarily been rendered according to any particular sequence or embodiment.
The invention and accompanying drawings will now be discussed in reference to the numerals provided therein so as to enable one skilled in the art to practice the present invention. The drawings and descriptions are exemplary of various aspects of the invention and are not intended to narrow the scope of the appended claims. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. It is noted that the inventor can be his own lexicographer. The inventor expressly elects, as his own lexicographer, to use only the plain and ordinary meaning of terms in the specification and claims unless they clearly state otherwise and then further, expressly set forth the “special” definition of that term and explain how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventor's intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
The inventors are also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.
Further, the inventors fully informed of the standards and application of the special provisions of 35 U.S.C. § 112, ¶ 6. Thus, the use of the words “function,” “means” or “step” in the Detailed Description of the Invention or claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. § 112, ¶ 6, to define the invention. To the contrary, if the provisions of 35 U.S.C. § 112, ¶ 6 are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for” and the specific function (e.g., “means for filtering”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for . . . ” or “step for . . . ” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventor not to invoke the provisions of 35 U.S.C. § 112, ¶ 6. Moreover, even if the provisions of 35 U.S.C. § 112, ¶ 6 are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the illustrated embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.
In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed inventions may be applied. Thus, the full scope of the inventions is not limited to the examples that are described below.
A battery indicator 30 is attached to the top portion 18 along an outer rim thereof and includes a plurality of LED lights 32 which indicate, by the number of illuminated LED lights 32, the amount of charge left in the battery. That is, where all three LED lights 32 are illuminated, the battery may be fully charged or nearly fully charged. When two lights 32 are illuminated, the battery may be between about 50 percent and 75 percent charged. When only one of the plurality of lights 32 is illuminated, the battery may be between about 25 and 50 percent charged and when no lights 32 are illuminated, the battery may be less than 25 percent charged or fully or nearly fully depleted such that the light 10 will not illuminate.

The threaded upper portion of the battery housing 66 is threaded into a threaded aperture in the plate assembly 68 to secure the battery 60. Once the base portion 12 is removed, the battery housing 66 can be unscrewed from the plate assembly 68 to release and remove the battery from the light 10. The battery 60 can then be easily replaced if needed. When the battery housing 66 is fully engaged with the plate assembly 68, the terminals of the battery 66 are in electrical contact with electrical contacts provided in the battery housing and/or the contacts of the battery connector 74.
Lights 62 and 64 are coupled to a bottom of the plate assembly 68 so as to be configured to direct light into the base portion 12. Because the base portion 12 is clear or otherwise substantially light transparent, light from the lights 62 and 64 is passed through the base portion 12. While only two such lights 62 and 64 are shown, a plurality of such lights in a radial arrangement may be provided around the plate assembly so that the base portion 12 is substantially evenly lit around the entire circumference of the base portion 12. The exterior surface 76 of the battery compartment 66 and the bottom surface 78 of the plate assembly 68 may be coated with a reflective paint or film in order to direct substantially all of the light from the lights 62 and 64 through the base portion 12 in order to maximize brightness of the light 12.
As previously mentioned, the base portion 12 has a generally cylindrical shape with a dome shaped bottom portion 13 and defines an inner chamber 15 having a generally cylindrical shape that extends from proximate the plate assembly 68 to the bottom portion 13. The outer wall 11 of the base portion 12 is comprised of a plurality of radially extending curved rib portions 80, that form a plurality of partial toroidal surfaces 80′ that circumferentially extend around and form the outer surface of the base portion 12. These partial toroidal surfaces 80′ help to disperse light from the lights 62 and 64 in a radial manner and from top to bottom of the base portion 12. That is, the ribbed configuration of the base portion 12 helps to more evenly and uniformly disperse light from the base portion 12 even thought the lights 62 and 64 are positioned at the top of the base portion 12. The outer wall 11 is spaced from the battery housing 66 on all sides so that light from the lights 62 and 64 can spread by light reflective properties throughout the base portion 12 to illuminate the entire base portion 12.
