This invention relates to the automatic opening and closing of typical forced
hot air
registers deflector and cover.
The usual and common practice of deflecting hot air as it leaves the register
is to place a
separate deflector on the register.
These deflectors are meant to direct the hot air to the center of the room
where it is most
desired.
The current available deflectors do not act as a cover and are inconvenient as
they
protrude above the floor and are therefore in a position to be easily
displaced and
broken.
It is the purpose of this invention to prevent this occurrence by
automatically closing the
deflector almost flat with the floor and at the same time acting as a cover
for the register
preventing such things as dust, dirt, spilled liquids, dropped objects,
insects, etc. from
entering the hot air system.
The heat from the hot air system causes the bimetallic spring to move, (either
expand or
contract), causing the actuating rod to push up the register deflector/cover.
The
bimetallic spring holds the deflector/cover in the fully opened position until
the heat shuts
down thereby causing the spring to rotate in the opposite direction and
lowering the
deflector/cover to the fully closed position.
