BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates generally to a flashlight attachable to a cordless drill. More specifically, the invention is a flashlight case having a bracket which is adapted
10 for attachment to a conventional spare bit holder built-in to the housing of a cordless drill in order to provide illumination while drilling.
2. DESCRIPTION OF THE RELATED ART
The related art of interest describes various portable L5 power tools utilizing an accessory light in various locations, but none discloses the present invention which provides for attaching a flashlight onto a portable drill by means of a bracket attached to the flashlight, case which snaps into a conventional bit holder (s) in the portable drill housing. There is a need for a small illumination source for a portable drill,
and particularly a cordless drill, which can be readily attached to the drill to greatly assist in the drilling process, especially in a small, crowded, and shaded areas. The related art will be discussed in the order of perceived relevance to the present invention.

SUMMARY OF THE INVENTION
The present invention is a flashlight and bracket attachment for a cordless drill. The illumination is necessary in dark areas such as inside cabinets, closets, attics, and for basement ceilings, and the like. Conventional portable drills now have one or two storage spaces inside a cavity molded into the drill body and having a clip holder for screwdriver bits. Therefore, according to the present invention, the flashlight has a bracket attached on the side of the flashlight case, the bracket comprising a rectangular base element and a cylindrical element for insertion in the clip holder. In this manner, advantage is taken of the existing clip holder.
Accordingly, it is a principal object of the invention to provide an illumination source attachment device for a cordless drill having an integrated screwdriver bit holder.
It is another object of the invention to provide a flashlight with a holder device for fitting the modified screwdriver bit holder cavity of a cordless drill.
It is a further object of the invention to provide a holder component having a cylindrical attachment element for removable attachment to the cordless drill.
It is an object of the invention to provide improved elements and arrangements thereof for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes. These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention, as shown in FIG. 1, is directed to a flashlight and bracket device 10 for attachment to a cordless
drill 12 to provide illumination on the work area for the worker 14 using the drill 12. As depicted in FIGS. 1, 2 and 3, a conventional battery operated flashlight 16 has a holder element
or bracket 18 consisting of two contiguous parts, namely, a rectangular base element 20 and a cylindrical element 22 adapted for being gripped by the spring clip 24 (partially hidden in
FIG. 1) in the cavity 26 in the body of the drill 12. These cavities 26 are conventionally molded in a cordless drill 12 on opposite sides for holding screwdriver bits.
The flashlight 16 has the bracket 18 attached by any of the
following methods, including riveting, bolting, welding, gluing, wire ties, and the like. Alternatively, the bracket 18 may be
formed in one piece with the flashlight case by molding, etc. The flashlight 16, shown schematically in the drawings, is battery powered and has an otherwise conventional case including a barrel for containing the batteries and a head housing a bulb, reflector, and lens. The flashlight 16 may have an external
on/off switch, or may have on/off switch operated by rotating the head section.
FIG. 4 and 5 illustrate a side view and a front or rear view, respectively of the configuration of the bracket 18, including the rectangular base element 20 and the integral
cylindrical element 22. These elements 20 and 22 can be made in one piece by molding or attached by welding and the like as noted above . The bracket 18 may be made from any suitable
material, including steel, aluminum, copper, die cast alloys, plastics, hard rubber, wood, etc.
Thus, a flashlight combined with a simplified holder element can be immediately attached to a cordless drill having at least one cavity with a holding clip for a screwdriver or a drill bit, or for holding a chuck key. It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
