     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to umbrellas and, more specifically, to an umbrella having housing with a deployable canopy extendable and retractable therefrom. The canopy comprises a material covering supported by flexible ribs and rib extension retainers. The umbrella further provides an adjustable strap extending between the exterior distal ends and a handle on one distal end of a flexible collapsible material. The adjustable strap further provides a D-ring and clasp on one end allowing for removal of said strap. 
     2. Description of the Prior Art 
     There are other tubular devices designed for umbrellas. Typical of these is U.S. Pat. No. 5,188,137 issued to Simonelli on Feb. 23, 1993. 
     While this umbrella may be suitable for the purposes for which it was designed, it would not be as suitable for the purposes of the present invention, as hereinafter described. 
     SUMMARY OF THE PRESENT INVENTION 
     The benefits that are described here would be most beneficial to an umbrella: that consists of an elongated housing having an open top. A collapsible canopy is carried on the elongated housing. A mechanism is for operating the canopy so that when the canopy is placed in a closed position it will be stored within the open top of the elongated housing and when the canopy is placed in the opened position the canopy will extend outwardly form the open top over the elongated housing hereinafter referred to as the umbrella. 
     The first benefit is the process for further stabilizing the canopy, during use of the umbrella on windy days. The second benefit is the addition of a multi-purpose, adjustable, and removable strap. The third benefit is a collapsible carrying handle, also used when opening the umbrella. The benefits are canopy stabilization, adjustable strap and, collapsible carrying handle. 
     The first significant improvement to this type of umbrella is a means to further stabilize the canopy. It has been observed that when using the umbrella in windy weather the canopy has a tendency to rise up a few inches. A mechanism has been designed to give the canopy added stability in that type of weather. The process used consist of cords of selected strong material, such as nylon braided cord, and a spacer that is placed close to the base where the ribs are attached. 
     The cords need to be of a precise length, and strategically attached to the inside open top of the elongated housing, and the other end of the cords attached to the fabric canopy preferably close to the ribs. 
     When the canopy is opened the attached cords will be pulled out of the top of the shaft. In the full opened position; the cords place a tension on the canopy because of their length and the position of attachment to the canopy. This will actually further form the shape of the canopy, but more importantly enable the canopy to be more stable when wind passes over or under the canopy. When the umbrella is closed the cords will be pulled inside the elongated housing because of their attachment to the canopy. 
     The cords need to be of such a length that they will be pulled completely inside the housing, but not so short that they will put excessive tension on the canopy when closed. When considering the following two characteristics for the purpose of manufacturing: “Simplicity of operation when opening and closing the umbrella, and also using a minimum amount of material” arrangement of the cords for an umbrella having eight ribs would be as follows: A cord used for this purpose would be “Y” shaped . . . . The single end is secured to the inside of the open top of the elongated housing between two of the ribs . . . . The other two ends of the cord will be secured to the canopy next to the rib so that the tension would be most effective. This process is repeated for the remaining number of ribs. The same process could be used for an umbrella having an odd number of ribs with the exception that one cord would be single and not “Y” shaped. 
     The other part of the canopy stabilization process is accomplished by the placement of a device such as a spacer; for holding the ribs apart at a point near the base member where the ribs attach. It was discovered that the ribs are pushed together at this point when a force is placed in the opposite direction of the full open canopy; such as wind lifting the canopy. Although the distance is small at the base it is multiplied as it extends along the length of the rib. An illustration of this would be the distance that a windshield wiper moves as it sweeps across a windshield. At the pivot point it may only travel 1 inch. This would equate to 10 inches of travel if measured at a point further outwardly along the wiper blade. In the case of this umbrella it was found that a spacer placed on the center rod near the base of the ribs reduced canopy movement and gives the canopy a more rigid feel especially when air pressure would cause it to lift up. 
     The second improvement to the umbrella is the addition of a multipurpose, adjustable, and removable strap. The strap could be adjusted to different lengths for varying applications. The longer length would be used for carrying the umbrella over ones shoulder. This is beneficial when the umbrella is not in use but still needs to be carried such as walking inside a mall. Because the umbrella is being carried over ones shoulder it would free-up that one hand normally used just for the purpose of carrying the needed umbrella. 
     The strap could easily be adjusted to its shortest length. At this length the umbrella could be carried along with another object in the same hand; such as with a briefcase, handbag, or computer case. Another function of this strap is the ability to place the umbrella over the extended handle of a suitcase like the ones on roller wheels that are pulled behind a person. This strap is also completely removable if so desired and small enough to be stored in a persons pocket or purse. This umbrella strap consists of a hooking devise on one end a snap or other fastening method at the other end. It also has snap bases at varying points along the strap for pre-positioned adjusting points . . . . A piece of stretch material is sewn at a central position along one side of the strap. It is added for the purpose of placing the umbrella over a suitcase handle . . . . 
     In order to support this type of strap, an umbrella would need two attaching points. The umbrella shown here has a ring fixed to the top of the elongated housing. The other end of the umbrella has double “D” rings installed . . . . 
     Removal of the strap “if desired” is as follows: Step A. Unsnap it. Step B. Pull the strap through the double “D” rings. Step C. Un-hook the other end from the single ring. Installation would be to reverse the order of steps Step C, B, A. 
     Two methods for adjusting the strap offered. One is fixed positions, and the other is variable positions. The fixed positions are accomplished with the use of the snaps, while the variable positions are accomplished with the use of the double “D” ring configuration. 
     Fixed positions are accomplished with the placement of snap bases along the strap. Two are offered for this application. The snap receptacle is on the end of the strap. In order to use the fixed positions the strap is pulled through the double “D” rings, and over the top of both rings. The strap length is changed depending on which snap base is used. 
     Variable positions can be accomplished with the use of the double “D” ring configuration offered. This is accomplished by utilizing the double “D” rings in the same manner that they would be used for when adjusting a motorcycle helmet strap. With this option the strap length could be adjusted for any clothing arrangement or personal preference. 
     The third improvement is the addition of a collapsible carrying handle. One benefit of this type handle is the ability to shorten the overall length of the umbrella by several inches. Another is; added cushion for the palm of ones hand; used when closing this type of umbrella. Another benefit would be an alternate location for the placement of the double “D” rings. 
     This handle is also used for hanging the umbrella in traditional places where other umbrellas&#39; are stored. The handle is made of flexible material that is able to collapse with minimum pressure, an example would be a nylon or leather strap. It is fastened to opposite sides at the bottom of the shaft. This offers a wider opening to grasp the umbrella 
     A primary object of the present invention is to provide an extendable retractable umbrella from a housing forming umbrella. 
     Another object of the present invention is to provide the umbrella with an adjustable strap extending between the umbrella distal ends that can be looped over a wheeled carrier handle. 
     Yet another object of the present invention is to provide the umbrella with an adjustable strap that can be looped over a user&#39;s shoulder. 
     Still yet another object of the present invention is to provide the umbrella with a handle positioned on one end of said umbrella with said handle made of flexible material that is able to collapse with minimum pressure, such as, a nylon or leather strap. 
     Another object of the present invention is to provide the umbrella with rib deployment retainers consisting of cords of selected strong material, such as nylon braided cord. 
     Yet another object of the present invention is to provide the umbrella with a spacer that is placed close to the base where the ribs are attached. 
     Additional objects of the present invention will appear as the description proceeds. 
     The present invention overcomes the shortcomings of the prior art by providing an umbrella having a housing forming with a deployable canopy extendable and retractable therefrom. The canopy comprises a material covering supported by flexible ribs and rib extension retainers. The umbrella further provides an adjustable strap extending between the exterior distal ends and a handle on one distal end of a flexible collapsible material. The adjustable strap further provides a D-ring and clasp on one end allowing for removal of said strap. 
     The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawing, which forms a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced.
