Abstract
An air guard assembly used to direct air forced through an overhead air diffuser toward the floor of a building. The assembly has a plurality of elongated linear baffles. Each baffle has a strip of magnetic material that adheres directly to metal ceiling structures to surround and enclose the diffuser within the assembly. A gripping tool having an elongated handle is used to locate the baffle adjacent the metal ceiling surface and remove the baffle therefrom. The baffle has a pair of grooves preventing the gripping tool from slipping off the baffle.
Claims12
An apparatus for directing air and dirt flowing from an air diffuser from a ceiling surface including magnetic holding means comprising:
- a plurality of elongated members mounted on the ceiling, each member having body means, neck means extending from the body means and shoulder means joined to the neck means defining groove means, and magnet means secured to the body means releasably attachable to magnetic holding means, the magnet means having a continuous top surface extending between opposite ends of the body means thereby releasably holding the member on the magnetic holding means adjacent the diffuser.
An apparatus for directing air and dirt moving from an air dispenser away from a ceiling surface including magnetic holding means comprising:
- first baffle means mounted on the surface, second baffle means mounted on the surface laterally spaced from the first baffle means, third baffle means mounted on the surface extended between the first and second baffle means, fourth baffle means mounted on the surface extended between the first and second baffle means and laterally spaced from the third baffle means, said first, second, third and fourth baffle means surrounding the air dispenser, each baffle means having body means, a neck secured to the body means and shoulder means joined to the neck to define a groove, and magnet means secured to the body means releasably attachable to the magnetic holding means on the surface, the magnet means having a continuous top surface extending between opposite ends of the body means thereby releasably holding the baffle means on the surface adjacent the air dispenser and preventing leakage of air and dirt leaving the air dispenser laterally through the baffle means.
An air control apparatus for an air diffuser releasably supported on a metal ceiling surface, the air control apparatus adapted to be located adjacent the ceiling surface for attachment thereto with gripping means, comprising:
- a plurality of elongated members surrounding the diffuser, each member having a tubular body, neck means attached to the body and shoulder means attached to the neck means defining a groove, the body having a continuous flat top surface having opposite ends, and magnetic means secured to the body releasably attachable to the metal ceiling surface, the magnetic means comprising a generally flat strip of magnetic material secured to the top surface of the body, the strip having a continuous top surface extending between the ends of the body thereby retaining the member on the ceiling surface adjacent the diffuser and minimizing leakage of air and dirt leaving the air dispenser laterally through the baffle means.
