Abstract
An apparatus for covering a vent that prevents material, either solid, liquid or gaseous from entering the vent. A plurality of baffles forms an annular space that provides a tortuous path for materials entering or leaving the vent. An alarm system may be added to the apparatus to alert/warn of tampering.
Claims20
A security vent cover for an air vent to inhibit the introduction of hazardous materials through the vent comprising:
- an inner baffle coupled to a top plate including one or more inner apertures adjacent to the top plate;
- an outer baffle coupled to the top plate;
- and
- a fastener coupled the vent to the inner baffle;
- wherein the inner and outer baffle form an annular space to create a tortuous air flow pathway from the vent to the exterior of the vent cover.
Security apparatus for covering a vent comprising,
- an inner baffle and an outer baffle;
- a fastener for coupling the inner baffle to the vent;
- a top plate coupled the baffles to form an annular space;
- and
- an alarm system coupled to the inner and outer baffles;
- wherein the inner baffle includes apertures to cause gas to flow through a tortuous path to/from the vent to outside the apparatus;
- wherein the introduction of hazardous materials through the vent is inhibited.
A security cover for a vent comprising,
- a base plate coupled to the vent,
- a cap comprising a plurality of baffles with an inner baffle coupled to the be plate, wherein the baffles form a tortuous path between the cap and the base plate to the vent, wherein the cap is coupled to the base plate by a plurality of locking pins.
A security cover for a vent comprising,
- a base plate coupled to a collar, wherein the collar is further coupled to the vent,
- a cap comprising a plurality of baffles coupled to the base plate,
- wherein the baffles form a tortuous path between the cap and the base plate the vent,
- wherein the cap is coupled to the base plate by a plurality of locking pins,
- wherein the collar is further coupled to base plate,
- wherein there is a cover baffle, a deflector baffle and a core baffle, the cover baffle and core baffle further comprising vent holes.
A security cover for a vent comprising,
- a base plate coupled to a collar, wherein the collar is further coupled to the vent,
- a cap comprising a plurality of baffles coupled to the base plate,
- a transmitter,
- wherein the baffles form a tortuous path between the cap and the base plate to the vent,
- wherein the cap is coupled to the base plate by a plurality of locking pins,
- wherein the collar is further coupled to base plate.
A security cover for a vent comprising,
- a base plate coupled to a collar, wherein the collar is further coupled to the vent,
- a cap comprising a plurality of baffles coupled to the base plate,
- wherein the baffles form a tortuous path between the cap and the base plate to the vent,
- wherein the cap is coupled to the base plate by a plurality of locking pins,
- wherein the collar is further coupled to base plate, and
- wherein the vent holes are covered by a screening material.
