Description
BRIEF SUMMARY OF THE INVENTION
The invention relates generally to a floor register or diffuser
which is provided with a plurality of spaced blades between which
air may pass from an air duct into a room. More particularly the
invention is directed to a construction which will permit the use
of decorative material such as aluminum, thereby to enhance the
appearance of the register and yet which will be strong enough to
support substantial weight.
Floor registers must be able to support considerable weight,
particularly because of persons walking or standing thereon.
Materials such as aluminum, which may have a very attractive
appearance, may nevertheless be relatively weak, compared to steel,
and thus, unable to support the necessary weight to enable it to be
used, for example, as a floor register. It is therefore, desirable
that the register, and particularly the blades thereof, be formed
of a material having high strength, such as steel. Steel however,
does not have the pleasing esthetic appearance of some other
materials, such as aluminum and it is therefore the principle
object of the present invention to provide a construction of floor
register wherein the blades are formed of a relatively strong
material, such as steel, and then covered with a material of
greater esthetic appeal, whereby the resulting product will have
the necessary inherent strength and yet will also be pleasing to
the eye.
A further object of the invention is to provide a floor register
wherein blades extend between opposed side or end marginal portions
of a frame member, which blades are formed preferably of steel and
which are covered with a decorative material of lesser strength
than steel which, by itself, in a member of the same size and shape
as steel, could not form the main structure of the register because
of its inability to support the required weight.
A further object of the invention is to provide a floor register
comprising a frame having opposed marginal side and end members,
two of such opposing members supporting a plurality of spaced steel
blades each covered with a sheath of material such as aluminum,
together with means on the register itself to hold the covering
sheath in place on each of the blades.
Other objects and advantages of the invention will become apparent
upon reading the following description, taken in conjunction with
the accompanying drawing, in which:
FIG. 1 is an elevational view of a floor register embodying the
present invention;
FIG. 2 is a longitudinal sectional view of the floor register taken

DETAILED DESCRIPTION
Referring now more particularly to the drawing, and especially to
FIGS. 1 and 2 thereof, the register of the present invention
includes a frame member generally indicated by the numeral 1 and
which consists of the opposed side marginal members 2 and 3, and
the opposed end marginal members 4 and 5.
These end and side marginal frame members may be secured together
in any suitable and well-known manner to provide the substantially
rectangular frame 1 of the floor register. As will appear more
fully hereinafter, the invention is particularly applicable for
registers wherein the blades thereof extend longitudinally between
the end members of the frame as shown in FIG. 1. It will be
understood, however, that if desired, the invention would be
equally applicable if the blades were to extend transversely of the
frame between the side members 2 and 3. Thus, the invention is not
intended to be limited to any particular direction in which the
blades extend and the claims herein are not intended to be so
construed.
Since aluminum makes a much more attractive appearance than does
steel, the present invention will be specifically described herein
as referring to the blades as being formed of steel and the
covering for the blades being made of aluminum. Other materials,
however, may occur to those skilled in the art which may be used as
coverings for the blades to enhance the appearance of the register.
If it were desired to form the entire register of aluminum,
including the blades thereof, and particularly where the blades
extend lengthwise of the register frame, in order to provide
strength equivalent to that obtained by steel blades, it would
require a blade depth, which would restrict its application in many
instances. In place of increasing the blade depth, additional
crossbraces could be utilized, although these would detract from
the linear appearance and increase the cost. It has thus been
determined that in order to give strength, as well as improved
esthetic appearance to such a floor register, the blades should be
formed of steel and then covered with a material of pleasing
appearance, such as aluminum.
The numeral 6 represents the floor of a room and 7 illustrates an
air duct through such floor. The register is adapted to fit such
air duct opening and the marginal portions of the frame 2, 3, 4 and
5 are adapted to overlie the portions of the floor 6 immediately
surrounding the opening 7 of the duct.
The end members of the frame 4 and 5 are provided with flange
portions 8 and 9 respectively, which are adapted to extend inwardly
of the air duct as shown in FIG. 2. A plurality of blade members 10
are spaced apart transversely of the register frame and extend
lengthwise thereof and are supported at their ends by the flanges 8
and 9. Each end of each blade 10 is suitably formed into a hooklike
member 11 adapted to be received within an opening in the adjacent
flange 8 and 9, as more clearly shown in FIG. 4. As illustrated,
the blades 10 are also supported by one or more cross braces
12.
The marginal side frame members 2 and 3 are provided with similar
flanges 13 and 14 which also extend into the air duct. Each flange
is suitably cut and bent as shown more clearly in FIGS. 3 and 6 to
provide an opening for the reception of the down-turned ends 15 of
the cross brace 12. Each of the blades 10 is welded or otherwise
suitably secured to the crossbrace 12 and thus this lends
additional support to such blades.
The side and end marginal portions of the frame are preferably
formed of extruded aluminum, although this fact is not intended to
form any part of the present invention. Each of the blades 10 is
provided with a covering or sheath generally indicated by the
numeral 16. Each sheath preferably takes the form of an inverted U
and thus comprises the spaced sides 17 and 18 and the cross piece
19 at the top thereof.
Each of these sheaths or coverings 16 may snugly receive a blade 10
as more clearly shown in FIG. 5. It is desirable, however, to
provide additional means for holding these coverings in place and
for that reason each of the marginal end members of the frame 4 and
5 is provided with an inturned lip 20 which overlies the ends of
the blades and the coverings thereon as may be clearly seen in FIG.
4.
The aluminum coverings may be extruded or formed from aluminum
sheet. In either event, it will be quite evident that the blades
themselves being formed of steel or other suitable metal having
sufficient strength, will support sufficient weight to make them
suitable for use in a floor register. The esthetic appearance of
the register may be considerably enhanced by the use of the
aluminum coverings. As mentioned above, these blades extending
longitudinally of the register could not be formed entirely of
aluminum and still have the required strength unless they were to
be made of such depth as to restrict its application in many
instances. Thus, the present invention provides a floor register
which not only has the required strength characteristics but also
the highly desirable improved esthetic appearance of an aluminum
register.
FIGS. 7 and 8 illustrate a modified form of the invention which has
certain advantages in addition to those mentioned above with
respect to the structure shown in FIGS. 1--6. In this modification
a channel member is added to the cross brace 12.
This channel member is indicated generally by the numeral 21 and
has the spaced sides 22 and 23. The channel is inverted to receive
the brace 12, as shown in FIG. 7, and is interposed between the
brace and the blades 10. In fact, the channel 21 is preferably
aluminum coated and is welded to the blades 10. When the structure
is assembled, the channel forms a unit with the register to receive
the wire brace.
It has been found that this channel, because of its greater width,
not only enhances the appearance of the entire assembly, but also
enables the register to support greater weight than is possible by
use of the wire brace alone.
Changes may be made in the form, construction and arrangement of
parts from those disclosed herein without in any way departing from
the spirit of the invention or sacrificing any of the attendant
advantages thereof, provided, however, that such changes fall
within the scope of the claims appended hereto.
