AND THE LIKE
Abstract
A structure to be used in buildings or the like for supporting
ceiling tiles as well as for supporting window curtains, shades, or
the like. An elongated extrusion has at its upper surface structure
for supporting the extrusion in a horizontal attitude from a
suitable beam or the like with the extrusion having an inner side
edge region adapted to support ceiling tiles and an outer side edge
region adapted to be located next to an upper frame member situated
over a window. Between its side edge regions the extrusion is
provided with a downwardly directed hollow channel defined by
vertical wall portions of the extrusion and an upper horizontal
wall portion extending between the vertical wall portions. These
vertical wall portions are respectively formed with grooves
extending parallel to each other longitudinally of the extrusion
and communicating with the interior of the channel. These grooves
are adapted to receive opposed side edges of a carrier structure
situated in the channel for carrying units such as window curtains,
Venetian blinds, or the like. This carrier structure is supported
exclusively by the location of its opposed side edges in the
grooves, so that there is no necessity of fastening the carrier
structure to the extrusion.

Description
BACKGROUND OF THE INVENTION
The present invention relates to structures to be used in buildings
and the like for supporting ceiling tiles.
For example, such structures are used to support ceiling tiles at a
given distance below a floor situated over the tiles so that the
floor forms with the tiles a hollow space into which recessed
lighting fixtures may extend and which may also form a plenum
chamber for air-conditioning purposes, for example.
With that part of the structure of this type which is located
adjacent windows, it becomes necessary to provide for attachment to
the structure of components to be used in connection with carrying
window curtains, Venetian blinds, and the like. At the present time
considerable problems are encountered in fastening to suitable
elements the structures which are required to carry the Venetian
blinds, curtains, or the like, and in addition problems are
encountered in providing for flow of air for air-conditioning
purposes. Thus, a considerable amount of labor and time is required
to fasten brackets or other elements which are to carry window
shades, curtains, or the like, and also considerable time and labor
is involved in providing for air-flow from a room to the plenum
chamber over the ceiling tiles.
SUMMARY OF THE INVENTION
It is accordingly a primary object of the present invention to
provide a structure which will greatly reduce the time and labor
required in connection with provision of suitable supports for
window shades, Venetian blinds, or the like, as well as in
connection with provision of openings through which air can flow to
the plenum chamber from a room beneath the ceiling tiles.
In particular, it is an object of the present invention to provide
a relatively inexpensive extrusion which can readily be mounted for
the purpose not only of supporting ceiling tiles but also of
accommodating components which carry Venetian blinds, curtains, or
the like, as well as to provide for flow of air into the plenum
chamber.
In particular, it is an object of the invention to provide a
structure which will enable components which carry curtains, window
shades, or the like to be readily placed in position with an
extremely small amount of labor in an extremely short time while
requiring no fasteners to be used.
It is also an object of the present invention to provide an
extrusion of this type which can be readily mounted in its position
of use. Also, it is an object of the present invention to provide
simple components to be used with the extrusion and which are
readily assembled therewith, without the use of any fasteners, for
the purposes of supporting window shades, Venetian blinds, or the
like, as well as for supporting the extrusion itself and aligning a
series of extrusions.
According to the invention the extrusion has an inner side edge
region which is adapted to support ceiling tiles and an outer side
edge region which is adapted to be located next to a frame member
over a window. The extrusion has an upper surface provided with a
means for supporting the extrusion from a building element. The
extrusion is formed with a downwardly directed hollow channel
extending longitudinally of the extrusion and defined between a
pair of vertical wall portions of the extrusion and an upper
horizontal wall portion extending between the vertical wall
portions. These vertical wall portions are respectively formed with
grooves which are parallel to each other and extend longitudinally
of the extrusion, these grooves being horizontal and communicating
with the interior of the channel. A carrier means is provided for
carrying units such as Venetian blinds, window curtains, or the
like. This carrier means has a pair of opposed side edges
respectively located in these extrusion grooves and supported
exclusively by location of the side edges of the carrier means in
the grooves, so that no fasteners are required with the structure
of the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, there is illustrated in FIG. 1 an
extrusion 10 according to the invention. This extrusion 10 is
continuously extruded through a suitable extrusion die and is cut
into any desired lengths. The extrusion is made preferably of a
metal which has a certain amount of springiness for a purpose
referred to below. The extrusion 10 may be made from aluminum, for
example, and, if desired, it may be coated as with a suitable
covering of paint of any desired color.
The extrusion 10 of the invention has an inner side edge region 12
which is adapted to support ceiling tiles 14 in the manner shown
schematically at the lower right portion of FIG. 1. The extrusion
also has an outer side edge region 16 adapted to be located next to
a frame member 18 located over a window and forming for example, a
window closure component. At its outer side edge region 16 the
extrusion 10 may have an upwardly directed flange 20 to be fastened
by suitable rivets 22 to a downwardly extending flange 24 of the
frame member 18 which in turn may be fastened by suitable rivets or
the like to a stationary structural component 26.
At its upper surface, the extrusion 10 is provided with a means 28
for supporting the extrusion from any suitable structural element
such as the beam 30 which may be a black iron channel. As is
apparent particularly from FIG. 2, the means 28 is in the form of a
web of the extrusion which extends vertically and is formed with
openings 32. These openings 32 are adapted to receive legs 34 of
suspending elements 36 in the form of plates adapted to extend
around the beams 30 and having angled legs 34 which respectively
pass through the openings 32. Through this simple structure it
becomes possible to support the extrusions 10 at the required
elevation in a horizontal attitude, and the rivets 22 will fixedly
hold the extrusions at their proper horizontal attitude and
elevation.
The web 28 extends upwardly from a downwardly directed hollow
channel 38 of the extrusion. This channel 38 is defined between a
pair of vertical wall portions 40 and 42 of the extrusion 10. These
vertical wall portions are interconnected by an upper horizontal
wall portion 44. The vertical wall portions 40 and 42 are
respectively formed with grooves 46 and 48 which are parallel to
each other and extend horizontally, longitudinally of the
extrusion. These grooves 46 and 48 communicate with the interior of
the channel 38, with the groove 48 being an upper groove situated
next to the horizontal wall 44 while the groove 46 is a lower
groove situated adjacent the lower surface of the extrusion 10. The
lower groove 46 is limited at its lower region by an inwardly
extending rib 50 which is formed with a downwardly directed
inclined surface 52 forming a bevel for a purpose referred to
below.
In the example shown in FIGS. 1 and 2, the channel 38 is adapted to
support in its interior a carrier means 54 for carrying vertically
extending curtains which can be horizontally shifted for covering
and uncovering a window. The carrier means 54 is itself in the form
of an extrusion which may be made of the same material as the
extrusion 10. This carrier means 54 has a pair of opposed side
edges 56 and 58 which are respectively located in the grooves 48
and 46. Thus it will be seen that the side edges 56 and 58 are
upper and lower side edges of the carrier means 54. This carrier
means is supported only and exclusively by the location of the side
edges 56 and 58 respectively in the grooves 48 and 46.
As is apparent from FIGS. 1 and 2, the carrier means 54 is itself
formed with a pair of channels 60 and 62. The channel 62 is adapted
to support glides which are adapted to slide along the interior of
the channel 62. These glides will have upper portions situated
within the channel 62 and will be formed with grooves or the like
for receiving the ribs 64. These glides have lower eyes adapted to
receive hooks or the like from which a curtain is suspended. Thus
the glides in a well known manner will simply slip along the
channel 62 in order to close or open a curtain, and suitable
strings, wires, cords, or the like, may be used to interconnect
this series of glides with each other.
The channel 60 will accommodate control cords guided over suitable
rollers and actuating suitable pushing or pulling elements which
are connected with the end glides in the channel 62 so that through
manipulation of these cords it is possible to open and close the
curtains. This structure located in the channel 60 and 62 for
supporting the curtain is conventional and forms no part of the
invention.
As is apparent from FIGS. 1 and 2, the side edge 58 of the carrier
means 54 is in the form of a rib having a convexly curved
configuration while the side edge 56 simply forms an extension of
the upper wall of the carrier means 54. With this construction it
is only necessary, in order to mount the carrier means 54 in the
channel 38, for the operator first to place the edge 56 in the
groove 48, and then to snap the rib 58 past the rib 50. For this
purpose the rib 58 will first slide along the bevel 52, with the
extrusion 10 yielding sufficiently so that the side edge 58 will
snap into the groove 46. Through this exceedingly simple rapid
operation it becomes possible to reliably mount the carrier means
54 in the channel 38 without the use of any fasteners. An
exceedingly small amount of time and labor is required for this
purpose. Once the extrusions 10 are mounted in position in
end-to-end relation, it is a simple matter to snap the extrusions
which form the carrier means 54 one after the other in position so
that curtains for windows of any desired width can be readily
accommodated. Thus, without the use of any fasteners such as
screws, bolts and nuts, rivets, or the like, it is possible with
the invention to quickly snap the carrier means 54 in its operative
position, greatly reducing the time and labor conventionally
required for this purpose.
The space above the ceiling tiles 14 and the extrusions 10, between
the latter and the next-upper floor will usually form a plenum
chamber 66 into which air is directed through suitable blowers or
the like from the room beneath the ceiling tiles 14 and extrusions
10. From the plenum chamber 66 as is well known, the air is either
recirculated or simply discharged to the outer atmosphere.
According to a further feature of the invention, the extrusion 10
is formed between the channel 38 and its inner side edge region 12
with suitable openings 68 (FIG. 2) through which the air can
readily flow into the plenum chamber 16. For this purpose it is
preferred to form the extrusion 10 with a second channel 70 defined
between the vertical walls 72 and the horizontal wall 74 which is
formed with the opening 68. These openings 68 are simply punched
through the wall 74 after the extrusion is formed. In this way the
extrusion forms a recess 70 for receiving the returning air and
serving to recess the openings 68 upwardly beyond the bottom
surface of the ceiling tiles and the extrusion 10. Thus, dust or
other particles which are like to collect along the edges of the
openings 68 will not be exposed at the lowest surface area of the
extrusion 10.
In order to align successive extrusions and to further support the
extrusions, they are provided with elongated angle portions 76
forming extensions of the walls 72 and defining a pair of grooves
which are directed toward each other and located directly over the
wall 74. These grooves 78 are adapted to receive opposed side edges
of a horizontal web 80 of a plurality of T-shaped support members
82 which have upwardly directed webs 84 formed with openings 86
corresponding to the openings 32 and coacting with the hangar
elements 36 in the manner described above. These members 82 are of
sufficiently short length and are distributed in such a way as to
provide for the required flow of air through the openings 68. Also
the members 82 will be arranged across the butting edges of a pair
of successive extrusions 10 extending into the grooves 78 of both
extrusions so as to accurately align successive extrusions with
each other.
It is not essential to provide the extrusions of the invention with
the additional channels 70 and with the capability of providing for
flow of air into a plenum chamber 66. In certain buildings where
such plenum chambers are not provided, it is possible to use an
extrusion 90 as shown in FIG. 3. This extrusion 90 is identical
with the extrusion 10 in all respects except that it does not have
the channel 70. However, for alignment purposes the extrusion 90 is
formed with the elongated angle portions 92 defining at the upper
surface of the extrusion 90 a pair of grooves 94 directed toward
each other. These grooves are adapted to receive simple alignment
bars whose opposite side edges are located in the grooves 94. These
bars will extend across the adjoining edges of successive
extrusions 90 for the purpose of aligning them with each other. The
extrusion 90 will accommodate a carrier means 54 in precisely the
same way as described above in connection with FIGS. 1 and 2.
When it is desired to support, in front of the windows, Venetian
blinds rather than curtains, the structure of FIGS. 4 and 5 may be
used. Referring to FIG. 4, there is illustrated therein an
extrusion 100 which is identical with the extrusion 10 except that
the extrusion 100 is formed with a downwardly directed hollow
channel 102 which is deeper than the channel 38. This channel 102
is defined between a pair of vertical walls 104 and 106
interconnected by a wall 108 provided with a means for supporting
the extrusion from a structural element such as the beam 30. Thus,
the extrusion may include an upwardly directed web 110 formed with
openings 112 to coact with the hangar elements 36 in the manner
described above.
The walls 104 and 106 are respectively formed with grooves 114 and
116 located adjacent the lower surface of the extrusion and
situated at the same elevation, these grooves extending parallel to
each other in a horizontal direction, longitudinally of the
extrusion. It will be noted that the grooves 114 and 116 also
communicate with the interior of the channel 102.
In order to support Venetian blind units 118, a carrier means 120
is provided. This carrier means 120 takes the form of simple bars
or plates made of any suitable metal and having opposed side edges
122 and 124 respectively situated in the grooves 114 and 116, so
that the carrier means 120 is also supported only and exclusively
by location of its opposed side edges in the grooves of the
downwardly directed channel of the extrusion.
When each extrusion 100 is mounted in its position of use, a given
number of the plates or bars 120 are slipped into the grooves 114
and 116. These plates can be easily shifted along the grooves 114
and 116. FIG. 5 shows a pair of such plates 120 in one of the
extrusions 100, FIG. 5 also illustrating openings 112 of the web
110. When an extremely wide window is encountered it is necessary
to situate a series of Venetian blinds next to each other. Thus,
FIG. 5 shows three Venetian blind units 118a, 118b, and 118c
situated next to each other. In order to mount these units in
position, the several carrier means 120 are shifted along the
grooves 114 and 116. When the left unit 118a is mounted in the
channel 102, with a suitable plate 120 beneath the unillustrated
left end thereof, the left plate 120 can be slipped beneath the
right end of the unit 118a, which is shown in FIG. 5. Then the left
end of the unit 118b can be slipped into the channel 102 over the
left plate 120 of FIG. 5, and then right plate 120 of FIG. 5 can be
moved beneath the right end of the unit 118b. Then the next unit
118c can be mounted in the same way. The tapes and cords of the
Venetian blind units are sufficiently flexible so that when
mounting the last of the series of Venetian blinds the supports or
carriers 120 therefor can readily be shifted to first permit the
last unit to be inserted and then the carrier means 120 can be
shifted beneath the ends of the last Venetian blind unit. As is
apparent from FIG. 5, the several carrier means 120 are short
enough so that the operating cords 122 for tilting and raising or
lowering the slats 124 can be free to operate without engaging the
plates 120. Moreover it will be noted that with this arrangement
the slats 124 of the successive Venetian blinds will be located
directly next to each other forming the effect of one continuous
Venetian blind for an extremely wide window.
Except for the above differences the embodiment of FIGS. 4 and 5 is
identical with that of FIG. 1, as is apparent from a comparison of
FIG. 4 with FIG. 1. However, where a plenum chamber and air
conditioning is not provided it is possible to eliminate a second
channel 126 of the extrusion 100 and instead to provide it only
with a pair of angle portions similar to the angle portions 92 of
FIG. 3, to receive alignment bars for aligning successive
extrusions 100 with respect to each other in a manner described
above in connection with FIG. 3.
Thus, it is apparent that with the invention relatively simple
inexpensive extrusions can be readily mounted in position for
accommodating, without the use of fasteners, suitable carrier means
for carrying curtains, Venetian blinds, or the like, and in
addition it is a simple matter to provide the extrusions with the
possibility of accommodating the air flow into the plenum chamber
over the extrusion and ceiling tiles.
