## Background
FIELD OF THE INVENTION
This invention relates to the field of automobile windshield sun protector. More specifically, the invention comprises a windshield sun protector which allows a two step process to expand and collapse.
BACKGROUND OF THE INVENTION
There are many known kinds of automobile windshield sun protectors in the market. All of them have one or more of the following design shortcomings. In some designs, installation requires drilling holes or the use of adhesives which results in irreversible damage to the automobile, such as disclosed in U.S. Pat. No. 5,653,278. Windshield sun protectors are often cumbersome and difficult to deploy and store, such as U.S. Pat. No. 5,649,584. More problems occur when installed sun protectors partially block a driver's front view, creating a dangerous condition, such as disclosed in U.S. Pat. No. 5,653,278.
Thus, there is a heartfelt need for an automobile windshield sun protector that can be installed without damaging the vehicle and easily deployed, and does not obstruct the driver's front view when not in use.
SUMMARY OF THE INVENTION
The present invention solves the problems described above by providing an automobile windshield shade system having multiple retractable sun visors.

The second sun visor tube extends along the second telescoping slide rail linearly to distance from the automobile sun visor. The first sun visor tube extends along the first telescoping slide rail linearly to a distance beyond the second sun visor tube. The third sun visor tube remains in a static relationship with the automobile sun visor. The system is deployed by two movements by a user. The first movement extends the first sun visor tube, which engages the second sun visor tube and extends it also. The second movement pulls the second retractable sun visor downward, bringing with it by its connection through rings to the first and third retractable sun visors.

DETAILED DESCRIPTION OF THE INVENTION
Directing attention to the FIGS, the sunshade protector system, shown herein in FIGS. 1-10, is assembled on base 2, which is secured to passenger sun visor 1 by two hand-tightened knobs 3. The user, typically a driver of the vehicle to which the present invention is attached and operated as a plurality of retractable sunshades for an automobile windshield, places base 2 on the passenger sun visor 1. Installation does not require any tools and does not cause any damage to sun visor 1. While illustrated and described herein as being used near the front windshield of an automobile, substituting suction cups for knobs 3 allows the sunshade protector system to be used on the rear window of an automobile. The system is easy to expand and retract. To expand and deploy the sunshades, the user pulls the first roll-up sunshade visor, sun visor tube 4, all the way from the passenger side of the windshield to the driver side of the windshield, as shown in a transition from FIG. 1, then to FIG. 2, and then to FIG. 3. Counter weight 21 is then hooked on second sun visor tail handle 11 and left on the front dashboard as shown in FIG. 4. Thus, only two steps are necessary to fully expand the sunshade protector system of the present invention.
To retract the sunshade protector, the user releases counter weight 21 from the second sun visor handle 11. In an embodiment, sun visors tubes 4, 5, 6 are spring-loaded to automatically retract their respective sun visors. Then the first sun visor tube 4 is pushed all the way back to passenger sun visor 1, as shown in FIG. 1. Only two steps are required to fully pack up the sunshade protector. The retraction process can be viewed as transitioning from FIG. 4, to FIG. 3, to FIG. 2, and finally back to FIG. 1.
The entire system is placed on the base 2. The base is mounted on the passenger sun visor 1 by two hand tightened mounting knobs 3.
As shown in FIG. 5, there are three substantially parallel, automatic roll up sun visor tubes 4, 5, 6 that are similar in size and dimension. Each of the sun visor tubes 4, 5 and 6 have lengths that are about the same dimension as the width of passenger sun visor 1. Sun visor tube 4 is connected to base 2 by a three-step telescopic slide rail 13. Sun visor tube 5 is connected to base 2 by two-step, telescopic slide rail 14. Sun visor tube 6 is connected to base 2 by a rubber connector 15.
In an embodiment, both slide rails 13, 14 have lengths similar to the lengths of sun visor tubes 4, 5, 6. Both slide rails 13, 14 prevent themselves from sliding into separate pieces. In an embodiment, slide rails 13, 14 include a retaining clip that engages when the slide rails 13, 14 are retracted, which prevents slide rails 13, 14 from sliding out while driving.
As shown in FIG. 6, from the view of the opposite side of sun visor 1, in an embodiment, sun visor tubes 4, 5 are partially connected by a group of triggers 18, 19, 20. When pulling sun visor tube 4 to driver side, bottom trigger 18 pulls sun visor tube 5 out by coming into contact with and engaging top trigger 19. When pushing first sun visor tube 4 back to the passenger side, bottom trigger 18 pushes the sun visor tube 5 back to the passenger side by top trigger 20. Use of triggers 18, 19, 20 enables a user to horizontally fully expand and retract the system by simply pulling or pushing the first sun visor tube 4.
Also, in an embodiment, each of the three sun visors has a tail handle 10, 11, 12. The first sun visor handle 10 and the second sun visor handle 11 are connected by a ring 16. The second sun visor handle 11 and the third sun visor handle 12 are connected by another ring 17. The ring 16 can horizontally move on the handles 10 and 11. The ring 17 can horizontally move on the handles 11 and 12. The counter weight 21 causes sun visor 8 to be pulled out sun visor tube 5. The second sun visor handle 11 will pull the first sun visor handle 10 and the third sun visor handle 12 its connection to them by rings 16, 17. This can be more clearly seen in FIG. 7, described below.
In an embodiment, three sun visor tubes are used and each sun visor tube is about the same width as the passenger sun visor. This design works for most automobiles as automobile windshield internal width is about three times as the passenger sun visor width. However, the present invention can utilize four, or even more, sun visor tubes in a similar configuration as shown to apply it to wider vehicles or longitudinally in buses and recreational vehicles.
In an embodiment, the three sun visor tubes 4, 5, 6 can also be embodied as self-locking sun visor tubes. Self-locking sun visor tubes having internal locking mechanisms that are similar to the internal locking mechanisms found in manual pull out projector screens. The user can pull out the sun visor and lock it at any position. To retract the sun visor, the user only needs to slightly pull the sun visor to unlock and a spring-loaded retraction mechanism retracts the sun visor. In such embodiments, the counter weight item 21 is not needed for keeping the sun visor extended.
FIG. 7 shows a profile view of base 2 mounted on sun visor 1. As can be seen more clearly, sun visors 7, 8, 9 are connected by their respective tail handles 10,11, 12, by rings 16, 17. Also more visible in FIG. 7 are triggers 18 and 19. FIG. 8 shows more clearly the interface between sun visor tube 5 and 6. Of particular interest are the two telescoping portions of slide rail 13. And while trigger 20 is shown in FIG. 8 from the front perspective of sun visor 1, triggers 18, 19 are shown in contact with each other as seen from the rear perspective of visor 1 in FIG. 9, showing full extension of sun visor tubes 4, 5.
FIG. 10 shows a partial perspective view of the system when fully and horizontally extended and partially deployed. Once again, sliding rail 13 is shown in multiple lengths, and sliding rail 14 only shows one portion as the remaining portion is out of view. Also of note here is ring 16 is more clearly seen connecting tail handles 10 and 11.
While a system and method for a two-pull windshield shade has been illustrated and described in detail, it is to be understood that numerous modifications can be made to embodiments of the present invention without departing from the spirit thereof.
