Abstract
ABSTRACT OF THE DISCLOSURE
A flexible goose neck extension shaft affixed at one end to the standardized flash gun mount located on photographic cameras and affixed at the other end to a photographic flash gun having a standardized mount. The mounts at each end of the extension conduct electricity by way of a connecting wire running between these extension end mounts such that when a photograph is taken causing a current to be released from the camera's flash gun mount, that current is carried through the extension shaft to the attached flash gun so that a resulting flash of light from the flash gun is produced for the taking of the photograph.
Unlike prior art, the combination of electrical conductivity and flexible goose neck extension enables the combined features of fast indirect lighting shots in all directions, without tripods, external power requirements, without the loss of two-handed action in support of the camera ( freeing the hands to operate the camera) , or the necessity of another human to hold the flash gun for continuous action shots.

Description
~iERA FLASH GUN FLEXA~LE SHQFT EXTENSIO~
The present invention relates generally to photography apparatus and more particularly a unique flexible extension gun connecting a camera to a flash gun in a desired position with respect to a camera during flash photography.
Cameras equiped to use an external flash gun all have a common generic mount to which any flash gun from any manufacturer in the world may b~ attached. Directly affixing a flash gun to a camara limits the operator to the creation of pictures requiring direct frontal lighting. Photographs requiring indirect lighting or lighting from an angle can not be obtained from any camera where the flash yun is limited to or directly mounted to or a part of the camera.
Our aim is to bounce light off walls, etc., using the current invention. In prior art, various -forms of current flash or light gun holders exist, but all with decided drawbacks. For example, the "portable lamp unit for illuminating photographic subjects" described and illustrated in Canadian Patent 646507 requires an external power source of AC current, and a tripod to support it. Although indirect and angled lighting is possible using this invention, the photographer must continually stop photographing to walk over to his portable lamp unit to readjust light directions in between shots, making action shots utilizing ~6~
varied lighting combinations all but impossible.
In another example of prior art photographic systems, the ZS "universal 'on-camera' sensor ~racket" is described and illustrated in Canadian Patent 646507. When attached to the camera, the lighl source becomes rigid "naking indirect lighting or lighting from an angle impossible. The same device can be detached -from the camera, but at that point the photographer must then either be satisfied with trying to operate his camera with a single hand while holding the flash in his other hand, or the photographer must mount his camera on a tripod, ther~by limiting movement while he holds and directs the light source with his other hand. Detached from the camera, using a flash gun either ~5 becomes a iuggling act or the photography itself becomes limited and confined to set poses. The "Computer Type Electronic Photoflash" described and illustrated in United State~ Patent 4~29624 also requires either one-handed camera operation with the -flash in the other hand or use of a tripod to compensate.
In another e~ample of prior art, the "photographic flash apparatus" described and illustrated in United States Patent 4242616 is a flash gun although fixed to the camera when mounted, offers a swival light gun. Unfortunately this swival only moves vertically, limiting indirect lighting shots for a camera held squarely to either ~eing bounce off the ceiling or off the floor.
Similiar drawbacks found in a rigid bar can be seen the "Bounced Flash ~dapter" described and illustrated in Canadlan Patent 616872~
The most radi~al approach of prior art to this problem can be seen in the "light-diverting attachment for photographic flash units" as described and illustrated in United States Patent 41Z9898. Essentially this invention is a flexible hollow tube that can be attached to the front of a flash unit. When light comes out of the flash unit, it proceeds down the reflective inner tube, which can be bent in any direction. This invention does not require one handed photography, tripods, limited set shots, external power sources, but unfortunately the tube itself compromises the flash as the flash proceeds down the hollow tupe to the point that what comes out at the other end is far diminished from the original light output of the original flash.
More i~mportantly, it does not adapt universaly.
Thus, prior to the present invention, the problem remains for any photographer of being able to fast indirect lighting shots, without being limited by a tripod, without external power requirements, and without losing one of his hands or those of another human being while taking two-handed action shots. The present invention solves all of these problems and meets all of these requirements simply and eloquently. The present invention consists of a f lexible extension between a photographic camera and photographic flash gun as a means for the transmission of an 3~`~
electrical charge from the photographic camera to the flash gun so tha-t a flash of light is emited From the flash gun as the photographic camera exposes its film for a picture. The present invention lS comprised of a top head assembly which connects to any photographic flash gun ment for a 35 millimeter SLR camera, a bottom tail assembly ohich thereby connects to any photographic camera external flash gun connector, and a center flexible shaft thereby connecting the above top head assembly to the bottom tail assembly.
The flexible shaft is composed of a flexible goose neck metal tubing covered by a flexible corrugated rubber or plastic tubing to give it extra strenth, protection, and estetics. This shaft may be bent in any direction before the photogr~pher takes his photograph, enabling indirect lighting shots in all directions. Once bent, the shaft of the present invention remains rigid~ holding whatever flash gun that may be attached to it in the exact position the photographer placed it, while allowing the photographer to take his photograph using both his hands to hold the camera. Tripods, external power sources, extra individuals to hold flash guns are simply not neaded using the present invention, and further there is no los5 of flash output because the flash is directed exactly, not indirectly, in the direction desired by the photographer~ However, the current inventions greatest angles of light contrasting is achied by bouncing the light off walls, ceilinys, etc.
When the photographer takes his picture, an electrical charge i~ released to the external flash mount on the outside of the camera. If a flash gun is directly affixed to th1s mount, then the current passes through the flash gun's compatible mount 100 into the ~lash gun itself causing the flash gun to emite a -Flash of light. Using the present invention the electronic result o-f producing a flash through the flash gun is the same, but it i5 achieved indirectly through contacts and a wire running through the length of the present invention. That is to say that in the 105 mount of the present invention there is an electrical contact similiar to that found on the flash gun itself. When a photograph is taken and an electrical charge is emited out of the camera's flash mount, that electrical charge is received by contact in the present lnvention's camera top head assembly.
110 Internal within the present invention is a conductive insulated wire conected to present invention's camera top head assembly.
This conductive insulated wire runs from this top head assembly contact, through the invention's flexible goose neck metal tubing, and into the present invention's bottom tail assembly 115 where this wire is also connected to a bottom tail assembly contact. The bottom tail assembly is directly fastened to the flash gun so that its connector contacts with the electrical connector residing in the flash gun connector. The result i5 that the electrical charge then passes through the present 120 invention into the flash gun, which then produces the flash.
In summary, the present invention is a device for performing a flexible extension thereby between a photographic camera and photographic flash gun as a means for the transmission of an electrical charge fromt he photographic camera to the flahs 125 gun so that a flash of light is emited fromt he flash bas the the photographic camera exposes its film for a picture~
