PORTABLE SMOKING ROOM
Field of the Invention
The present invention relates to the field of smoking enclosures, and more
particularly, it relates to a portable smoking room.
Background of the Invention
In recent years, smoking has been prohibited in most public places including
office buildings, restaurants and bars, sports arenas and theatres, and
airports, mainly due to
the adverse health affects associated with inhaling second hand smoke. Certain
establishments
have set up designated smoking areas or enclosures to allow smokers to smoke
without having
to step outside. However, such designated smoking areas are diminishing in
numbers and the
smoking enclosures currently available can be very smoke laden despite the
presence of
exhaust vents to remove smoke particles from the enclosures. Although the
number of
smokers has decreased substantially, there still exists a need for a smoking
facility to
accommodate the needs of smokers.
Various smoking or air cleaning modules are available in the art. For example,
U.S. Patent No. 4,732,592 to Spengler describes a portable environmental clean
air facility
comprising a frame wherein clear plastic sheeting material maybe draped over
to form a clean
air section enclosure. A bypass damper is provided for controlling the air
flow velocity and
for producing negative pressure in the enclosure, withdrawing contaminated air
from the clean
air enclosure by the blower motor. U.S. Patent No. 5,537,787 to Abraham
describes a portable
smoking booth including an enclosure defining a smoking area and a purifier
system that
draws air from the enclosure and exhausts the air outside the enclosure. The
booth is movable
from one location to another location as an assembled unit and the wall and
door of the booth
is clear to enable a prospective user of the booth to view activity outside
the booth. However,

none of the smoking or clean air modules provides an easily transportable
smoking room that
enables a user to smoke a cigarette virtually wherever and whenever the user
desires.
Consequently, there exists a need for a portable and collapsible smoking room
to enable a user
to conveniently transport and assemble such room so that the user may smoke a
cigarette at an
appropriate indoor location.
Summar,~of the Invention
It is therefore an object of the present invention to provide a portable
smoking
room wherein the smoking room may be disassembled and conveniently transported
to a
different location where the portable smoking room may be reassembled for use.
In accordance with the present invention, there is provided a portable smoking
room having a flexible enclosure detachably mounted to a frame, the flexible
enclosure
defining a room having a door. A first flexible duct is detachably mounted to
the frame such
that air within the flexible enclosure may be transported outside of the
flexible enclosure. A
fan detachably mounted to the first air duct creates negative pressure within
the flexible
enclosure such that air within the flexible enclosure may be drawn out though
the first flexible
duct. The frame may be disassembled when the flexible enclosure and the first
duct are
detached from the frame such that the flexible enclosure, the frame, the fan,
and the first duct
may be conveniently transported and reassembled at a different location.
The portable smoking room may also include a first mounting bracket
detachably secured to the frame such that a first end of the first flexible
duct may be
detachably mounted to the mounting bracket. A second end of the first flexible
duct is
detachably mounted to an intake end of a fan such that the fan may withdraw
smoke laden air
from the enclosure. Preferably, the fan is an inline fan. A first end of a
second flexible duct is
detachably mounted to an exhaust end of the fan such that smoke laden air
within the flexible
enclosure may be directed outside the flexible enclosure. Preferably, the
second end of the
2
CA 02487941 2004-11-19
second duct is detachably mounted to a second mounting bracket which is
detachably mounted
to a window such that the smoke laden air within the flexible enclosure may be
transported
outdoors.
In an embodiment of the invention, the door of the enclosure defines a
plurality
of apertures such that the fan may draw ambient air outside the flexible
enclosure into the
flexible enclosure. Preferably, the door is at least partially transparent
such that a user inside
the enclosure may view activity outside the flexible enclosure. The flexible
enclosure also
defines an aperture such that the first end of the first duct may be inserted
through the aperture
so that it may be detachably mounted to the first mounting bracket.
In another embodiment of the invention, the frame, the enclosure, the first
and
the second ducts, the fan, and the first and said second mounting brackets may
be disposed
within a container such that the portable smoking room may be conveniently
transported to
another location for reassembly.
In another embodiment of the invention, the portable smoking room includes a
light fixture detachably mounted to the frame. An actuator for activating the
fan and the light
fixture may be detachably mounted to the frame.

6
CA 02487941 2004-11-19
may be drawn out through first air duct 30 and released outdoors through
second air duct 50.
Outdoors is herein defined as the open air outside any building or enclosure
wherein the
smoking room may be positioned. Negative pressure exists when less air is
supplied to a space
than is exhausted from the space. The plurality of apertures 13 defined by
front panel 19
enables air outside of enclosure 10 to flow into enclosure 10. When fan 40 is
activated,
enclosure 10 becomes a negatively pressurized space because less air is
flowing into enclosure
through apertures 13 than is being exhausted from enclosure 10 through first
air duct 30
and second air duct 50. Fan 40 places a slight suction within enclosure 10 and
draws fresh air
in through apertures 13 on front panel 19 to replace the extracted
contaminated air. Preferably,
