## Abstract

A moveable barrier system comprising a first panel having a first vertical edge and a second vertical edge, the first vertical edge rotatably coupled to a first vertical surface along a first axis, and a second panel having a third vertical edge and a fourth vertical edge, the third vertical edge of the second panel rotatably coupled to the second vertical edge of the first panel, the fourth vertical edge of the second panel removably coupled to a second vertical surface. Each of the first and second panel have a structural layer that forms a vertical plane, spanning the first vertical edge and the second vertical edge, and a projectile resistant layer that is resistant to projectile impact. The first panel and the second panel are configured to move from a stored position into an active position when in use.

## Claims

### Claim 1

A moveable barrier system comprising:
a first panel having a first vertical edge and a second vertical edge, the first vertical edge rotatably coupled to a first portion of a perimeter of a room along a first axis, the perimeter of the room formed by one or more walls and defining a first area; and
a second panel having a third vertical edge and a fourth vertical edge, the third vertical edge of the second panel rotatably coupled to the second vertical edge of the first panel, the fourth vertical edge of the second panel removably coupled to a second portion of the perimeter of the room;
the first panel having:
a first structural layer that forms a vertical plane, spanning the first vertical edge and the second vertical edge,
a first projectile resistant layer that is resistant to projectile impact, and
a second projectile resistant layer that is resistant to projectile impact; and
the second panel having:
a second structural layer that forms a vertical plane, spanning the third vertical edge and the fourth vertical edge,
a third projectile resistant layer that is resistant to projectile impact, and
a fourth projectile resistant layer that is resistant to projectile impact
the first panel and the second panel configured to move from a stored position into an active position,
wherein, in the stored position, both the first panel and the second panel are positioned substantially parallel to and overlayed with a third portion of the perimeter of the room, the fourth vertical edge of the second panel is positioned along a second axis that is displaced a first distance from the first axis, and
in the active position, the first panel, the second panel, and a fourth portion of the perimeter of the room completely enclose a second area created between the first panel, the second panel, and the fourth portion of the perimeter of the room, the second area being within the first area, wherein the first panel and the second panel form an angle of less than 180 degrees, the second panel is coupled to the second portion of the perimeter of the room along a coupling axis that is displaced a second distance from the first axis, such that the second distance is greater than the first distance, and the second area is defined such that an entire group of people within the first area can move into the second area as the first panel and the second panel move from the stored position into the active position and the entire group of people can remain completely enclosed in the second area while the panels are in the active position.

### Claim 2 (depends on 1)

The moveable barrier system of claim 1 wherein the first structural layer of the first panel is positioned between the first projectile resistant layer and the second projectile resistant layer, and
the second structural layer of the second panel is positioned between the third projectile resistant layer and the fourth projectile resistant layer.

### Claim 3 (depends on 1)

The moveable barrier system of claim 1 wherein the first structural layer and the second structural layer further has a property that provides resistance to projectile impact.

### Claim 4 (depends on 1)

The moveable barrier system of claim 1 wherein the first projectile resistant layer has a first tensile strength value, the second projectile resistant layer has a second tensile strength value, the third projectile resistant layer has a third tensile strength value, and the fourth projectile resistant layer has a fourth tensile strength value, such that the first tensile strength value is approximately the same as the third tensile strength value and the second tensile strength value is approximately the same as the fourth tensile strength value.

### Claim 5 (depends on 4)

The moveable barrier system of claim 4 wherein the first tensile strength value is at least 3.5 gigapascals.

### Claim 6 (depends on 2)

The moveable barrier system of claim 2 further comprising:
a first internal projectile layer of the first panel and a second internal projectile layer of the first panel, the first internal projectile layer positioned between the first projectile layer and the first structural layer, the second internal projectile layer positioned between the second projectile resistant layer and the first structural layer, and
a third internal projectile layer of the second panel and a fourth internal projectile layer of the second panel, the third internal projectile layer positioned between the third projectile resistant layer and the second structural layer, the fourth internal projectile layer positioned between the fourth projectile resistant layer and the second structural layer.

### Claim 7 (depends on 6)

The moveable barrier system of claim 6 further comprising at least one handle disposed on the second panel.

### Claim 8 (depends on 6)

The moveable barrier system of claim 6 further comprising a locking mechanism disposed on the fourth vertical edge of the second panel configured to couple to the second vertical surface when the first panel and the second panel are positioned in the active position.

### Claim 9 (depends on 8)

The moveable barrier system of claim 8 further comprising an indicator configured to signal when the first panel and the second panel are moved away from the stored position.

### Claim 10 (depends on 9)

The moveable barrier system of claim 9 wherein the indicator provides a visual signal when the first panel and the second panel are moved away from the stored position.

### Claim 11 (depends on 9)

The moveable barrier system of claim 9 wherein the indicator provides an aural signal when the first panel and the second panel are moved away from the stored position.

### Claim 12 (depends on 9)

The moveable barrier system of claim 9 wherein the indicator provides an electronic signal to at least one of authorities or rescue personnel when the first panel and the second panel are moved away from the stored position.
