(12) As used herein, the term ballistic shade system refers to material designed to provide ballistic protection to an opening in a wall of a building. The ballistic material can be deployed or placed out of the way using the entire system of the invention. Unlike standard roller shades or roll up metal doors, like garage doors or the like, in order to provide ballistic protection, the system has to be able to hold the ballistic material in place when engaged, such as when hit by bullets, a blast, or the like, during an entry attempt. If not held in place, the material is blown aside, providing easy entry. Therefore, a system that holds the length edges is critical to performance. While no system is totally impervious or completely resistant to high powered weapons or explosives, if protection is provided for a period of time (e.g. half an hour, an hour, 2 hours or more), it provides sufficient time for authorities or other help to arrive and control the situation from outside the building. The present ballistic shade system is a roller system which, when it engages ballistic material over the opening in a wall of a building (i.e. rolled down to cover the opening), provides protection from entry due to such ballistic assault.

(13) As used herein, the term opening in an interior wall of a building refers to standard openings which appear in both the exterior walls and interior walls of a building. Such openings include windows, doors, pass-throughs, and the like. The system is designed to be mounted on the interior surface of a wall, e.g. the interior wall of an exterior wall. For example, the inside wall inside an office or the like.

(14) As used herein, the term flexible ballistic material refers to any blast and bullet resistant flexible material that can be rolled up but can still provide ballistic protection, unlike some materials (like Kevlar) which cannot. An example is the material made by Safe Zone Ballistics LLC, but the present invention includes any such material. In one embodiment, ballistic material is material that provides protection to at least NIJ III-A level or to 7.62 level. It can also be low-hazard blast resistant. Typically, such material has a weight of at least about 0.8 lbs per sq ft though some materials are about 3.3 lbs per sq ft or more. It is a flexible ballistic material designed to be a shade, i.e. sized and designed to be rolled up on a roller. In one embodiment, the ballistic material comprises multiple plies of a woven polymeric material. In another embodiment, there is horizontal stitching in a manner to help the fabric to roll evenly.

(15) As used herein, the term boltrope refers to a rope being sewn into the first and second length edge of the ballistic shade with a flange centered inside the ballistic material and a boltrope ball for moving through the side tracks. An exemplary version is shown in FIG. 2. The boltrope ball positioned in the guide tracks holds the shade in place if it is hit by a ballistic event.

(16) As used herein, the term ballistic protection refers to a system wherein the system protects entry from a bullet or the like through an opening in a wall when the system is engaged covering the opening.

(17) As used herein, the term roller refers to a roller that the ballistic material is rolled up on. The ballistic material is rolled on or off (providing the material up or down over the opening) by a motor positioned in the roller. In one embodiment, there are teeth in the track as well to hold the curtain in place.

(18) As used herein, the term motorized roller refers to a motorized drive, such as a belt drive, for turning the roller one way or the other for the purpose of extending or retracting the curtain. The motor can be AC or DC and is a reversible motor for going in both directions. In one embodiment, the motor is inside the roller and in another embodiment, the motor is mounted externally to the roller and is connected to the roller with a drive belt.

(19) As used herein, the term side guide tracks refers to channels designed to be mounted to the left and right of the opening in the wall. They are designed to channel the edges of the ballistic material up and down, while holding the edges in and keeping them from pushing out of the channel when a ballistic event hits the ballistic material. The guides each have a guide channel for the long edges of flexible ballistic material and an adjoining guide channel in communication with the guide channel for the ballistic material designed to accept the boltrope. There may also be space between the side guide tracks and the wall for insertion of a ballistic steel plate.

(20) As used herein, the term ballistic steel plate refers to ballistic material positioned to protect the guide tracks. It is positioned between the side guide tracks and the wall for the purpose of protecting the channels. It does not cover the opening in the door. The side guide tracks and ballistic plates can be bolted to the structure with lag bolts.

(21) As used herein, a bottom bar is a heavy horizontal bar at the bottom of the shade to provide the weight needed to pull the curtain down as the curtain is lowered. The purpose is also to provide rigidity to the bottom of the curtain. It also is useful because it limits the ability of an attacker to reach under the curtain. The bar can be fastened to the bottom of the ballistic fabric with steel straps and rivets or the like.

DRAWINGS

(22) Now referring to the drawings, FIG. 1 is a top perspective view of the present system mounted on the inside surface of an outside inside wall, having a window as the opening (though this could be a door or any other wall opening, or could be an interior wall with an inside surface). In this view, the ballistic shade system 1 is mounted on the interior surface 2 of wall 3. In this view, the shade system 1 is mounted to the wall studs 4 of the window 5. In this view, side guide tracks 8 are attached to wall 3 into the wall studs 4. Boltrope 9 can be seen on either side of ballistic material 6 with one end sewn into the fabric and the boltrope ball end travels in the guide track. Motor 10 deploys and retrieves the ballistic material. In this view, we can see the system 1 in the undeployed, or stowed, view with ballistic material 6 rolled up on a roller 20 (as seen in the next figure, FIG. 2).

(23) FIG. 2 is a close up view of one side of the ballistic material 6. The guide track 20 holds boltrope ball 21 of boltrope 9 while opposite boltrope end 23 is sewn into ballistic material's longitudinal length. The boltrope ball 21 travels in guide tracks 8 and keeps the shade in place in case of a ballistic hit by the strength of the boltrope ball staying in the guide tracks. It also guides the shade evenly into a deployed state. Channel 25 is shown as a space for insertion of ballistic steel plate 26 to protect the channels.

(24) FIG. 3 is a frontal view of the ballistic system 1 in the non-deployed mode. Opening 30 is the opening to be protected. Left and right guide channels 8 are shown.

(25) FIG. 4 is a frontal view of the ballistic system 1 which is fully deployed and covers opening 30 from FIG. 3. The shade is deployed into the outside track with the boltrope keeping the movement smooth and keeping the ballistic material in place. In this view, the bottom bar 29 at the bottom of the shade is shown.

(26) During use, the motor is engaged and turns the roller. The ballistic material is guided off of the roller and guided by the boltrope into the side tracks till the opening is entirely covered. In reversing, the motor rolls the ballistic material back up on the roller.

(27) Those skilled in the art to which the present invention pertains may make modifications resulting in other embodiments employing principles of the present invention without departing from its spirit or characteristics, particularly upon considering the foregoing teachings. Accordingly, the described embodiments are to be considered in all respects only as illustrative, and not restrictive, and the scope of the present invention is, therefore, indicated by the appended claims rather than by the foregoing description or drawings. Consequently, while the present invention has been described with reference to particular embodiments, modifications of structure, sequence, materials, and the like apparent to those skilled in the art still fall within the scope of the invention as claimed by the applicant.
