PORTABLE LIGHT HAVING A MODULAR BASE

BACKGROUND

People often engage in activities wherein a portable light is useful, both for illuminating the object of one's attention, as well as for providing a warning to others that one is present. For example, many people are active during the nighttime for reasons such as their job, exercise, transportation, and maintenance of their property. A portable light may be critical to illuminate the individual's surroundings so as to effectively perform their objective and avoid potential hazards. The use of a handheld light as a signaling device has been common since its inception. For example, a person riding a bicycle or walking along a street at night may opt to employ a portable light to warn drivers to the person's presence, thereby increasing the safety of such activities.

However, various styles of portable lights may not be suitable for more than one role, often as a result of their means of attachment. For example, a portable light primarily configured to be carried in the hand may not be suitable for use during cycling when one needs one's hands to control the bicycle. Likewise, a light configured to be worn about an individual's head may not be suitable for illuminating certain types of dangers, such as those presented by stairs during a power outage. As such, what is needed is a portable light source having a modular design capable of affixing to various bases in various situations.

To the extent that the term “includes” or “including” is used in the specification or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed (e.g., A or B) it is intended to mean “A or B or both.” When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995). Also, to the extent that the terms “in” or “into” are used in the specification or the claims, it is intended to additionally mean “on” or “onto.” To the extent that the term “selectively” is used in the specification or the claims, it is intended to refer to a condition of a component wherein a user of the apparatus may activate or deactivate the feature or function of the component as is necessary or desired in use of the apparatus. To the extent that the term “operatively connected” is used in the specification or the claims, it is intended to mean that the identified components are connected in a way to perform a designated function. As used in the specification and the claims, the singular forms “a,” “an,” and “the” include the plural. Finally, where the term “about” is used in conjunction with a number, it is intended to include ±10% of the number. In other words, “about 10” may mean from 9 to 11.

As stated above, while the present application has been illustrated by the description of embodiments thereof, and while the embodiments have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art, having the benefit of the present application. Therefore, the application, in its broader aspects, is not limited to the specific details, illustrative examples shown, or any apparatus referred to. Departures may be made from such details, examples, and apparatuses without departing from the spirit or scope of the general inventive concept.
