The present invention relates to a flashlight, and more particularly to a flashlight with a rechargeable power source and movable port cover.
Many modern flashlights include rechargeable batteries that may or may not be removable. The rechargeable battery and/or the housing related thereto may be removable.
The background description disclosed anywhere in this patent application includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
In accordance with a preferred embodiment of the present invention there is provided a flashlight assembly that includes a tubular main body portion that includes a light source associated therewith, a tail portion that is removable from the tubular main body portion, a switch that is configured to selectively provide power to the light source, a battery assembly positioned in a battery assembly interior, and an alignment system that includes one of a first protrusion or a first recess associated with the battery housing and the other of the first protrusion or the first recess associated with the battery assembly interior. The tubular main body portion and tail portion cooperate to define the battery assembly interior. The tail portion includes a first charging opening defined therein that communicates the battery assembly interior with an exterior of the tail portion. The battery assembly includes a battery housing defining a battery housing interior, a rechargeable battery disposed in the battery housing interior, and at least a first charging receptacle associated with the battery housing. The battery assembly is in electrical communication with the light source. The first protrusion is received in the first recess and the first charging receptacle is aligned with the first charging opening, such that a charging jack can be inserted through the first charging opening and into the first charging receptacle. The first charging opening has generally the same shape as the first charging receptacle, so that the charging jack can fit through the first charging opening and into the first charging receptacle.
In a preferred embodiment, the tail portion includes a receptacle cover that is movable between a first position wherein the receptacle cover covers the first charging opening and a second position where the receptacle cover does not cover the first charging opening. The tubular main body portion defines a flashlight axis, and the cover is movable between the first and second positions along the flashlight axis. The tail portion includes an inner diameter that at least partially defines the battery assembly interior. An alignment flange having first and second ends may extend around at least a portion of the inner diameter and the first recess may be defined between the first and second ends of the alignment flange.
The tail portion may include a second charging opening defined therein that communicates the battery assembly interior with the exterior of the tail portion and the battery assembly may include a second charging receptacle associated with the battery housing. When the first protrusion is received in the first recess the second charging receptacle is aligned with the second charging opening, such that a charging or power jack can be inserted through the second charging opening and into the second charging receptacle. The battery housing includes a stop member extending outwardly therefrom, wherein the stop member abuts the alignment flange. The stop member may extend at least partially circumferentially around the battery housing.
In accordance with another preferred embodiment of the present invention there is provided a method of powering a flashlight assembly that includes a plurality of steps. The steps may include obtaining a flashlight assembly that includes a tubular main body portion that defines a main body portion battery assembly interior, and a tail portion that defines a tail battery assembly interior. The flashlight assembly includes an alignment system that includes one of a first protrusion or a first recess associated with the battery housing and the other of the first protrusion or the first recess associated with the tail battery assembly interior. The steps may also include inserting a portion of the battery assembly into the main body portion battery assembly interior, aligning the first protrusion with the first recess, placing the tail portion on the battery assembly such that the first protrusion is received in the first recess, and rotating the tail portion and the battery assembly to threadingly engage a first set of threads on the tail portion with a second set of threads on the tubular main body portion, whereby the electrically communicated with a light source in the tubular main body portion.
The battery assembly may include a first charging receptacle and the tail portion may include a first charging opening defined therein. After the tail portion and the battery assembly are rotated to threadingly engage the first set of threads on the tail portion with the second set of threads on the tubular main body portion, the first charging receptacle is aligned with the first charging opening. A spring may be housed or located in the tail battery assembly interior (e.g., extending into the battery assembly interior from the tail wall of the tail portion). When the tail portion and battery assembly are rotated to engage the first and second sets of threads along a path to align the first charging opening and first charging receptacle, and the spring is compressed.
The tail portion may include a receptacle cover, and the method may include the step of moving the receptacle cover from a first position where the receptacle cover covers the first charging opening to a second position where the receptacle cover does not cover the first charging opening.
