Description:

This patent application is a Continuation-In-Part of U.S. Utility patent application Ser. No. 11/409,844 filed on Apr. 24, 2006.

FIELD OF THE INVENTION

The present rollable screen door and mounting system generally relates to the field of screen doors used on private dwellings. More specifically, this device deals with a rollable screen door covering and mounting system for almost any residential entry or patio door, including sliding doors, and for motor homes.

DESCRIPTION OF THE RELATED ART

Traditional metal screen doors have several undesirable characteristics that previously have not been dealt with. With the screens stretched very tightly, small or large tears in the screen portion happen frequently and present an unsightly appearance and making the screen doors ineffective. The screens are generally not replaced until their appearance is extremely unsightly. If the metal screen door does not have an automatic door closing mechanism attached to it, the person closing the door must be sure that the door is latched properly. If it is left partially open, it will invite flies and other insects to enter. On metal screen doors having an automatic closing mechanism, the familiar sound of the screen door slamming shut is another annoying and undesirable characteristic.

There is a vast market for screen doors that needs to be filled. Less than 10 percent of the residential (entry or patio) door sales within the last six years are fitted with a screen door. Besides the doors sold with a screen door, there is the market of millions of installed doors that are suitable for retrofit or in need of a new screen door.

Approximately 90 percent of residential doors installed in apartment buildings are without screen doors. Most apartment and condominium buildings do not welcome screen doors because they are unsightly and detract from the appearance of the complex. Even in the rare situations where screen doors are allowed, the tenants do not want to spend their money on a permanent installation of a fixture that they are required to leave behind when they vacate their unit.

Therefore there exists a need for a new type of easily removable or rollable (roll up and roll down) screen door and mounting system that is convenient, functional, durable and inexpensive.

SUMMARY OF THE INVENTION

The primary advantage of the present invention is to provide a rollable screen door and mounting system which is convenient, functional, durable and inexpensive.

Another advantage is to provide a novel rollable screen door and mounting system that is portable, lightweight, and easy to carry, and move from one doorway to another.

Another advantage is to provide a novel rollable screen door and mounting system that is easy to install and remove, and readily rolls up and down as needed.

Another advantage is to provide a novel rollable screen door and mounting system that is easy to maintain by using a moistened soft cloth with a mild soap solution in order to clean it.

Another advantage is to supply a rollable screen door and mounting system that is flexible and not easily torn, or damaged.

Another advantage is to supply a rollable screen door and mounting system that can be rolled up from either the top or the bottom to additionally shorten its length.

Still another advantage of this invention is to provide a novel rollable screen door and mounting system that is readily width adjustable for differing doorway widths, and which has a mechanism for keeping the screen pressed into place against the door opening, to keep insects from getting in.

Yet, another advantage is to provide a novel rollable screen door and mounting system having a pleasing appearance and one that is durable and will last through many years of use.

It is another advantage to provide a rollable screen door and mounting system that has excellent outward visibility and daytime privacy.

Another advantage is to provide a rollable screen door and mounting system that lets in fresh air, better light and provides additional comfort for people who work in their house, apartment, motor home or condominium.

The rollable screen door and mounting system has as its primary structure an upright oriented fabric body having at least one mesh screen portion positioned inwardly from its respective edges. The respective mesh screen portions would normally encompass between 5-95 percent of the surface area of the fabric body. The preferred material for the mesh screen portion would be a fiberglass cloth. The fabric body and screen portion could also be made of a water repellant polyester material. Additionally, both the screen portion and the fabric body could also be made of a vinyl material, as well as a nylon material, or any other fiberglass-like material. The primary advantage of this invention is a novel removable or permanent fabric and screen door covering for millions of residents of homes, apartments, condominiums and motor homes, and other types of private dwellings that do not have the convenience of a screen door.

The top end of the fabric body on the preferred embodiment is folded back and horizontally stitched to form one or more sleeves to provide for varying heights of doors. An adjustable length tension rod is inserted through one of the sleeves. The sleeve chosen would be determined by the height of the doorway opening. Another method for adjusting the height of the fabric body is to rollup a portion of the bottom end or top end of the fabric body to provide a custom fit.

The respective areas on the preferred and alternate embodiments surrounding the mesh screen portion of the rollable screen door and mounting system form a top edge border panel, a left edge border panel, a right border panel, and an optional intermediate connecting panel and a bottom edge border panel. The edges of the respective border panels may be folded over and stitched to form a double thickness strip along the respective left side edge, right side edge and bottom edge. The rear surface of the respective left and right side edges have a single long strip or multiple strips of hook and loop fastener material secured thereto that would mate with matching strips of the same material attached along the inner surface of the doorway opening. These allow the left and right side edges of the screen door to snugly contact the inner surface of the doorway opening.

On both the preferred and the alternate embodiments of the rollable screen door and mounting system, a rear surface of the left edge border panel and right edge border panel have optional vertically spaced horizontal strips that each contain a plurality of laterally spaced pairs of male and female snap members. The snaps allow the width of the screen door to be adjusted to the width of the doorway opening.

The preferred embodiment of the rollable screen door and mounting system has been designed to be quickly and easily installed in a variety of doorway openings. First the adjustable length tension rod assembly is adjusted to a length just slightly less than the width of the doorway opening. Then it is inserted through one of the sleeves adjacent the top end of the upright oriented fabric body. The adjustable length rod assembly with the fabric body installed thereon is positioned within the doorway opening adjacent its top end. Now the adjustable length tension rod assembly is lengthened so that its opposite ends are tightened against the respective left and right side walls of the doorway opening. The hook fastening material or loop fastening material is attached to the respective left and right side walls of the doorway opening at positions that align with the hook or loop fastening material that is located along the left and right edges of the fabric body. With the upright oriented fabric body properly sealed adjacent the top and bottom of the doorway opening, the respective left and right side edges of the fabric body would be sealed against the respective left and right side walls of the doorway opening by the means of pressing the respective hook and loop fastening material together.

The alternate embodiment of the rollable screen door and mounting system will have a roll up mechanism whereby the screen door can be rolled on a roller tube, similar to a conventional window shade. The alternate embodiment of the fabric and screen door covering will be permanently affixed to the area above the door opening by the means of end brackets screwed into the wall surface. A variety of end brackets are available, the first set having the end brackets with a roller tube, enclosed by the means of a wire framework to be covered with decorative fabric. A second end bracket and roller tube set would have a front flange as a means to attach a decorative front panel with a tension rod at the lower rear to keep the fabric and screen door covering against the wall surface. A third end bracket and roller tube set will have two tension rods with the one in the front to hang a valance or a front panel with fabric loops at the top and the one in the rear to keep the fabric and screen door covering against the wall surface. A fourth end bracket and roller tube set would be mounted to a surface mounting plate with valance brackets for the forward tension rod and small rear brackets for the rear tension rod.

The above description, together with the objects of the invention and the various features of novelty that characterize the rollable screen door and mounting system and are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
