Abstract:
In order to provide temporary lighting solution in sometimes extreme conditions, this application has improved upon a prior patent by specifically incorporating a stabilizing rod to protect against extremely high winds or other inclement weather as well as electrical circuitry to enable a sufficient cool down period prior to stowing the device.

Description:
BACKGROUND OF THE INVENTION 
     A. Field of the Invention 
     This relates to portable sources of light, particularly light that needs to be spread over a wide range, but only on a temporary basis. The device can be used in a variety of environments and is expected to be subjected to extremes in conditions. 
     B. Prior Art 
     There is one other prior art reference that is closely related to the current application and is found at Medici, U.S. Pat. No. 6,322,230. This current patent application improves on the Medici patent by adding a guiding or stabilizing rod to insure that the light source remains constantly in place and prevents the swaying of the light during windy conditions. The Medici patent uses a plurality of guide wires to stabilize the light source but that in turn requires a great deal of surface area in which to deploy the device. At times this surface area is simply not available. 
     Additionally the means to deflate the device has been improved as well as an improvement in the circuitry in the present application. None of the improvements were contemplated by the original patent. 
     BRIEF SUMMARY OF THE INVENTION 
     This device is used for temporary lighting needs. This may be done in open fields at night, on ships at sea, or at events such as outdoor weddings and banquets. The light will be placed inside a long cylindrical tube that is inflatable. When the device is not used the tube is deflated and the tube is rolled up and stored on the unit. 
     The structure will be comprised of a base structure that has a top surface and a series of other supporting members. Under the top surface an area will be provided to house a power source that will be used to inflate the tube and activate the light within the tube during normal operation. 
     In order to make the device as user friendly as possible and to access the power source, which is likely to be a portable generator, a slidable mounting unit is placed on the structure. 
     On the top surface of the base structure will be mounted a cylindrical tube that houses the light and can be inflated to produce a light source. When the device is not used the tube with the light source can be easily folded and stowed. 
     On the top surface of the device will be the inflatable lighting structure. In operation, the power source will inflate the light structure. 
     One of the challenges in the prior art reference was that, because of the length or height of the light structure, the cylindrical tube may be subject to high winds, making the device unstable and impractical to use. 
     In the prior art reference a plurality of guide wires were contemplated to stabilize the device. This however proves to be impracticable in the field because of the area that is required to secure the wires to the ground surface. 
     A stabilizing rod that is secured to the top surface of the base structure will attach to a portion of the inflatable light structure or tube. More than one stabilizing rod may be used with this device to provide the needed stability. 
     Additionally it may be necessary to either lengthen or shorten the length of the cylindrical light structure. This may become necessary due to the outside conditions that make it difficult to stabilize the light structure or because of height concerns in a given area. A series of zippers around the perimeter of the light structure will provide a means to shorten or lengthen the light structure. 
     Near the bottom of the inflatable light structure will be a way to deflate the device, specifically an air vent. The air vent may be comprised of a variety of means to deflate the structure but a zipper is likely to be used. 
     There may be a variety of ways to anchor the inflatable light structure by placing one end of the stabilizing rod in a cavity on the top surface, probably a suitable way to anchor the rod. This makes removal and storage of the rod easy when the device is no longer needed. 
     Below the top surface plate will be the power source, which is more than likely to be a portable generator. One of the difficulties in the prior art reference is gaining access to the power source. In the current application a mounting slide is used to secure the power source. When the power source is to be accessed, the user simply slides the power source out and services the power source.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     This device is intended to be a portable light source. This device may be used in extreme conditions either on land or at sea. It is designed to provide sufficient lighting during times of extreme conditions. 
     The device  5  will be comprised of a base member  10  on top of which is mounted an inflatable light structure  15 , which is likely to be opaque in order to provide the necessary amount of lighting for any given condition. The light structure  15  will of a predetermined height or length and likely cylindrical and different lengths may be used. 
     The light structure  15  is likely to be of a synthetic material, although a variety of other materials may be used. In the light structure  15  will be a light (not depicted) secured to the interior of the tube. The tube should be able to withstand extreme conditions and should be strong enough for those conditions. Although many different materials may be used for the light structure and no specific material is being claimed, the primary considerations for the choice of material are the ability to withstand outdoor weather conditions and provide an adequate lighting area. 
     In order to stabilize the lighting structure, particularly during windy conditions, a rod attachment flap  22  will be positioned on the side of the light structure  15 . This rod attachment flap  22  will be secured to a stabilizing rod  20 . Many different methods may be used to attach the stabilizing rod  20  to the rod attachment flap and no one method is being claimed. 
     The stabilizing rod will be parallel to the lighting structure  15  and will provide a means to maintain the essentially vertical shape of the light structure during normal use. One end of the stabilizing rod will be placed in a cavity  21  on the top surface  11  of the base  10 . 
     Although in  FIG. 1 , only one rod attachment flap  22  is depicted, more than one rod attachment flap and stabilizing rod may be used. 
     When the device is operated, a power source  25  will be used to inflate the cylindrical lighting structure  15 . This power source  25  is likely to be a portable generator, although other sources may be used and the means to inflate will be a blower that will force air into the interior of the light structure. The blower will be operated by the power source. 
     The power source  25  will be placed on a slidable mounting surface  51  that is placed with a solid mounting tray  50  that is attached to the frame structure  12 . 
     The feet of the power source  25  will be placed in a plurality of grooves  26  on the slidable mounting surface for that purpose and straps  27  are used to further secure the power source to the slidable mounting surface  51 . 
     A crossbar  13  is placed across the side of the frame structure so that the power source is prevented from sliding beyond that point. 
     The sliding mount surface  51  will move such as depicted in  FIG. 8  so that the power source can easily be serviced by removing the crossbar  13  and sliding the power source out for service. 
     In order to insure that the power source remains in one position, a means to lock  29  the power source to the sliding mount  51  is provided. A means of attachment  28  that is secured to the frame allows the means to lock  29  to be secured as an additional means to prevent the power source from being moved. A number of means to lock the power source may be used and a wing nut is depicted in  FIG. 7   a  but other means are contemplated. 
     When the device is operated, the cylindrical tube sliding structure  15  will be inflated to a predetermined height. The light that is placed in the interior of the light structure is likely to produce a great deal of heat. Consequently, a means to operate the blower separately from the light is provided. This will allow the operator to extinguish the light prior to deflation in order to dissipate some of the heat from the light and prevent human injury during the deflation process as well as prevent injury to the device. 
     The electrical circuitry that operates the blower and the light will be constructed so that these elements will operate separately from each other. Because of the intense heat that is generated by the lamp inside the lighting structure a cool down period is recommended. The circuitry is configured so that the lamp can be turned off independent of the blower. Prior to the device being deflated the lamp can be turned off to allow the structure to cool down. 
     Once the appropriate cooling period has occurred, the cylindrical lighting structure  15  can be deflated. A means to deflate  30  will be used and is likely to be an air vent  30  at the bottom of the light structure  15 . A variety of air vents may be used and a zipper over a portion of the material for the light structure is one means to provide an air vent  30 . 
     In order to protect the air vent from damage as well as inadvertent opening, a protective flap  32  is likely to be placed over the vent. A means to open the air vent is also used and one choice would be a zipper. 
     In some situations it may be practical to either shorten or lengthen the light structure. This may be accomplished through a series of zippers (not depicted) around the perimeter of the light structure that can secure a portion of a section of the light structure to either shorten or lengthen the vertical dimensions of the light structure. 
     While the embodiments of the invention have been disclosed, certain modifications may be made by those skilled in the art to modify the invention without departing from the spirit of the invention.
