- 2. The device of claim 1 wherein the panel has a small circular hole formed therein.
- 3. The device of claim 1 wherein the panel is made of material selected from the group comprising wood, metal, plexiglass and urethane.
- 4. A device for installation within a frame of a window, said device comprising:a rectangular panel sized to fit in said frame, the panel having a first side, a second side, a third side, and a fourth side, each of the sides having an edge; a gasket affixed along the edge of the first side; at least two holding mechanisms arranged at even intervals along the third side, each of said mechanisms having: a base plate with a u-shaped end, the mechanism being arranged by pulling the u-shaped end of the base plate over the edge of the third side of the panel; a lever arm with a first end and a second end, the lever arm pivotally mounted on the base plate; a stop mounted on the base plate, said stop preventing pivotal movement of the lever arm past a predetermined point; a locking arm with a first end having an attachment point and a curved second end, the locking arm pivotally mounted on the base plate, with the first end of the locking arm overlapping the second end of the lever arm; a stopper disposed on the second end of the locking arm; a spring with a first end and a second end, the first end attached to a bracket mounted on the base plate, and the second end attached to the attachment point on the locking arm; and a catch mounted on the base plate, said catch rotatable between positions for holding the first end of the lever arm and releasing the first end of the lever arm; the mechanism being movable between an unlocked and a locked position by the pivotal movement of the lever arm after the first end of the lever arm is released from the catch, allowing spring-induced pivotal movement of the locking arm.
- 5. The device of claim 4 wherein the panel has a small circular hole formed therein.
- 6. The device of claim 4 wherein the panel is made of material selected from the group comprising wood, metal, plexiglass and urethane.
- 7. A device for installation within a frame of a window, said device comprising:a panel sized to fit in said frame, the panel having sides configured to complement the frame; and at least four holding mechanisms, each of which is mounted at the midpoint of each side, each of said mechanisms having: a lever arm with a first end and a second end, the lever arm pivotally mounted on the base plate; a stop mounted on the base plate, said stop preventing pivotal movement of the lever arm past a predetermined point; a locking arm with a first end having an attachment point and a curved second end, the locking arm pivotally mounted on the base plate, with the first end of the locking arm overlapping the second end of the lever arm; a stopper disposed on the second end of the locking arm; a spring with a first end and a second end, the first end attached to a bracket mounted on the base plate, and the second end attached to the attachment point on the locking arm; and a catch mounted on the base plate, said catch rotatable between positions for holding the first end of the lever arm and releasing the first end of the lever arm; and the mechanism being movable between an unlocked and a locked position by the pivotal movement of the lever arm after the first end of the lever arm is released from the catch, allowing spring-induced pivotal movement of the locking arm.
- 8. The device of claim 7 wherein the panel has a small circular hole formed therein.
- 9. The device of claim 7 wherein the panel is made of material selected from the group comprising wood, metal, plexiglass and urethane.
- 10. A device for installation within a frame of a window, said device comprising:a panel sized to fit in said frame, the panel having sides configured to complement the frame; at least four holding mechanisms, each of which is arranged at the midpoint of each side, each of said mechanism having: a base plate with a u-shaped end, the mechanism being arranged by pulling the u-shaped end of the base plate over a side of the panel; a lever arm with a first end and a second end, the lever arm pivotally mounted on the base plate; a stop mounted on the base plate, said stop preventing pivotal movement of the lever arm past a predetermined point; a locking arm with a first end having an attachment point and a curved second end, the locking arm pivotally mounted on the base plate, with the first end of the locking arm overlapping the second end of the lever arm; a stopper disposed on the second end of the locking arm; a spring with a first end and a second end, the first end attached to a bracket mounted on the base plate, and the second end attached to the attachment point on the locking arm; and a catch mounted on the base plate, said catch rotatable between positions for holding the first end of the lever arm and releasing the first end of the lever arm; the mechanism being movable between an unlocked and a locked position by the pivotal movement of the lever arm after the first end of the lever arm is released from the catch, allowing spring-induced pivotal movement of the locking arm.
- 11. The device of claim 10 wherein the panel has a small circular hole formed therein.
- 12. The device of claim 10 wherein the panel is made of material selected from the group comprising wood, metal, plexiglass and urethane.
- 13. A device for installation within a frame of a window, said device comprising:a rectangular panel sized to fit in said frame, the panel having a first side, a second side, a third side, and a fourth side, each of the sides having an edge; a gasket affixed along the edge of the first side; at least two holding mechanisms mounted at even intervals along the third side, each of said mechanisms having: a base plate with a guide; a u-shaped slide arm with a first end and an open second end having a handle perpendicularly disposed thereto, and further having two sides, each having an attachment point, the slide arm disposed in the guide; a stopper disposed on the first end of the slide arm; a bracket mounted on the base plate, the bracket having an attachment point; two springs, each having a first end and a second end, the first end of each spring being attached to the attachment point on the bracket, and the second end of each spring being attached to one of the attachment points on the sides of the slide arm; a catch mounted on the base plate, said catch rotatable between positions for holding the handle and releasing the handle; the mechanism being movable between an unlocked and a locked position by the spring-induced movement of the slide arm after the handle is released from the catch.
- 14. The device of claim 13 wherein the panel has a small circular hole formed therein.
- 15. The device of claim 13 wherein the panel is made of material selected from the group comprising wood, metal, plexiglass and urethane.
