[001] The present invention relates to a flexible telescopic flashlight with magnets at its both ends to retrieve metallic objects using its telescopic arm and to attach to metallic surfaces from the other end for hands free operation.
DESCRIPTION OF THE RELATED ART
Collins Chun Pong Chan & Waheed Khan FIELD OF INVENTION
[001] The present invention relates to a flexible telescopic flashlight with magnets at its both ends to retrieve metallic objects using its telescopic arm and to attach to metallic surfaces from the other end for hands free operation.
DESCRIPTION OF THE RELATED ART
[002] Flash lights with extendable lengths are used in lighting hard to reach areas, such as behind the cabinets or dark corners. Many extendable flash lights have been equipped with a magnet to pickup magnetically susceptible objects, such as nuts and bolts that have fallen in crannies and hard to reach areas.
The extendable flash lights disclosed in the prior art, however, have to be held by hand and cannot be easily operated hands free. It is inconvenient to hold a flashlight and implement a task whit one hand.
The extendable flash lights disclosed in the prior art, however, have to be held by hand and cannot be easily operated hands free. It is inconvenient to hold a flashlight and implement a task whit one hand.
[003] The presently disclosed flash light provides a larger and heavier base or end cap. The flash light can then be placed vertically and stably on a flat surface.
The base also has a magnet that will allow the flash light to stick to any metallic surface, thus it can be used hands free. The present flash light allows a user to illuminate and pick up items dropped in hard to reach areas, as well as, operating it hands free.
SUMMARY OF THE INVENTION
The base also has a magnet that will allow the flash light to stick to any metallic surface, thus it can be used hands free. The present flash light allows a user to illuminate and pick up items dropped in hard to reach areas, as well as, operating it hands free.
SUMMARY OF THE INVENTION
[004] An object of the present invention is to provide a flexible telescopic flash light comprised of a lighting member, flexible tubing, hollow cylinders having gradually increasing diameters attached together, and a chamfered base with a magnet.
[005] Another object of the present invention is to retrieve ferrous objects, which are trapped in an unreachable dark region by illuminating them using a lighting member and retrieving them by means of a magnet attached to the lighting member.
[006] Another object of the current invention is to access curved channels and hard to reach areas using a flexible shaft to let the retriever and illuminating device bend and assume the shape of the area.
[007] It is yet another object of the present invention to increase the safety and functionality of the flashlight by having an outwardly chamfered magnetic base that allows the flashlight to stick to ferrous surfaces such as metallic work table.
[008] It is another object of the present invention to reduce battery consumption by using LEDs.

DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE INVENTION
[019] While this invention is illustrated and described in a preferred embodiment, the device may be produced in many different configurations, forms and materials. The materials described below and the figures illustrate the preferred embodiment of the present invention. Therefore, the present disclosure is an example of the principles of the invention and its functional specifications for its construction and the invention is not limited to the embodiment which is showed and described here.
[020] Figure 1 shows the present flashlight having a telescopic shaft connected to a flexible tube which allows for the head of the flash light to swivel. The aforementioned flash light having a magnetic head which can retrieve the ferrous objects. Moreover, the base of the flashlight is attached to a circular magnet either to attach to ferrous surfaces or to stand on any surfaces in a vertical position, having a relatively larger and heavier base.
[021] The flashlight is comprised of a lighting housing 5, which is attached to a flexible shaft 7 via welding or any other attachment method. The lighting housing accommodates multiplicity, preferably four, LR44 circular batteries, not shown.
Any other type of battery can be used for this purpose. Multiplicity, preferably a set of three, light emitting diodes (LED) 4 is attached to the batteries. The illumination is controlled by a push button 6 (made from plastic or any other material suitable for this purpose) placed on the housing 5. The LEDs are covered by means of a chamfered cylindrical transparent plastic cover 3 having an extended ring attached to its open end. The cover 3 is located in the housing 5. This eliminates any movement when the housing head I is screwed and tightly fastened to the housing 5. Having all of the electrical parts in the head of the flashlight eliminates any need for having a long wire attached to the bottom end of the flashlight, which is the case in flashlights with batteries stored at the bottom or the shaft sections of the flashlight. This eliminates any twisting and, therefore, tearing of the electrical wires passing through the flexible portion of the flashlight. To complete the flashlight head, a round magnet 2, in the form of a hollow cylinder, is attached to the head 1 of the light housing. An electrical circuit is formed from one electrode of the battery through a conductor to the push button 6, then through a conductor, not shown, to one electrode of the LEDs mounted in the front end of the illumination housing. The electrical circuit emerges through a second electrode of the LEDs to electrically connect with a conductor connected to the other electrode of the battery.

[022] The flexible tube 7 is connected to a set of hollow cylinders 8a, 8b, 8c, 8d, and 8e, which have gradually increasing diameters, respectively. Said cylinders form a sliding telescopic shaft, which enables extending of the length of the flash light. In one embodiment of the present invention, using five cylinders, the length of the flash light can be extended from 6 3/4 inches to 21 1/2 inches.
Flashlights with any desired length can be constructed by changing the number or the length of the hollow cylinders. The bottom end of the last hollow cylinder 8e is attached to the main tube 9 of the flashlight and could slide therein.
Flashlights with any desired length can be constructed by changing the number or the length of the hollow cylinders. The bottom end of the last hollow cylinder 8e is attached to the main tube 9 of the flashlight and could slide therein.
[023] The flash light may also be equipped with a clip-on pocket holder 10 for ease of haulage of the device in ones pocket.
[024] Figure 3 shows the side view of the front end part of the present invention.
The magnet 2 accommodated in the head 1 is used to retrieve ferrous objects, such as screws, nails, bolts, nuts etc, which have fallen into a dark region with limited accessibility. The present flashlight can illuminate the dark zone, by pushing the button 6, and retrieve ferrous objects in the zone by its magnetic head.

[025] Figure 4 shows the flashlight in which the flexible shaft 7 is bent by 90 .
Figures 5 and 6 show the flashlight having its flexible tube 7 rotated in different angles, 180 degrees and more than 180 degree, respectively. The flexibility of the shaft facilitates the use of flashlight in the corners or twisted channels which are not reachable by a straight device. Figure 7 shows the flexible tube 7 and its internal flexible guiding metal wire 13, which passed through its center and helps the flexible shaft to maintain its shape.

Figure 7 shows the flexible tube 7 and its internal flexible guiding metal wire 13, which passed through its center and helps the flexible shaft to maintain its shape.
[026] Figures 8 and 9 show the magnetic base feature of the present invention.
A fixed screw 14 is attached to the bottom end part of the main tube 9. A
magnetic housing 11, having threaded sides, screws onto the screw 14. Said housing having a gradually increasing diameter, slightly larger than the diameter of the main tube 9. A magnet 12 is attached to the bottom end of housing 11.
The larger diameter of the magnetic head helps the flashlight to stand vertically on any flat surface and reduces the slippage. Furthermore, its magnet provides an attachment means for attaching the flash light to ferrous surfaces. The user can then easily operate the flash light hands free. This feature makes this flash light a light source which can attach to metallic surfaces. Furthermore, as the bottom magnet 12 is larger and stronger than magnet 2, it is possible to retrieve heavier ferrous objects.
