Description
BACKGROUND OF THE INVENTION
The present invention relates to a window drape which combines the
most desirable features of a vertical type window blind and a
conventional window drape.
The use of adjustable louver type vertical blinds is known and such
blinds are exemplified in U.S. Pat. Nos. 2,827,956; 2,828,817;
2,844,199; 3,038,534 and 3,061,005. Correspondingly, draw drapes
have been in use for a great many years and are preferred by many
users over the vertical blinds for esthetic reasons. Manifestly,
vertical window blinds while highly functional lack desired
esthetic qualities inherent in window coverings formed of a soft
fabric capable of being draped in a variety of ways.
SUMMARY OF THE INVENTION
One of the objects of may invention is the provision of a window
drape which combines the desirable characteristics of both a louver
type vertical blind and a conventional window drape, affording the
adjustable light transmission features of a vertical blind while
retaining the highly esthetic characteristics of a soft draped
window covering.
Another object of my invention is the provision of a window drape
of the foregoing character which is simple in construction,
efficient in operation and affords a highly esthetic
appearance.
Other and further objects and advantages of my invention will
become apparent from the following description when considered in
connection with the accompanying drawings.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-4, the drape 15 of the present invention is
shown detached from conventional support means 27 shown in FIGS. 9
and 10 employed with vertical blinds for providing both rotational
and traversing movement of the louvers of the blind. Such support
means are exemplified in U.S. Pat. Nos. 3,038,534 and 3,061,005.
The drape 15 of my invention comprises a fabric panel 16 formed of
a suitable open type weave affording a relatively high degree of
light and air transmission yet providing desired privacy. The upper
end of the panel preferably, is folded over upon itself and
stitched to provide an upper hem 17 which is coextensive with the
width of the panel. Suitably secured to the hem 17, at spaced
intervals, on the surface corresponding to the inner face of the
panel, are a plurality of pairs of snap fastener elements 19. The
lower edge of the panel 16 also is reversely bent and stitched to
provide a lower hem 21 and attached to said hem, at spaced
intervals, are a plurality of fabric tape sections 22 which are
stitched to the hem 21 only at their end portions, with the
intermediate portion of each tape section between the attached ends
being free of the panel. The tape sections 22 are disposed in
vertical registration with corresponding snap fastener elements
19.
A plurality of louvers 23 formed of suitable moderately rigid
opaque or semi translucent material are provided, each having a
length substantially equal to the vertical length of the fabric
panel 16 and having a width sufficient to effect overlapping of
adjacent louvers when the same are rotated to closed position, in a
manner well known in the art. Each louver 23 is provided with a
pair of complementary fastening elements 24 arranged to cooperate
with the fastening elements 19. The lower end of each louver 23 may
be tapered along the side edges to facilitate insertion into the
space between the panel 16 and a tape section 22. Thus, as will be
seen in FIG. 1, when the louvers 23 are assembled with the panel 16
there results a drape having alternately generally rigid opaque
sections A, each pair of adjacent sections A being separated by a
flexible light transmitting section B and C. It will be understood
that this alternating arrangement extends fully across the width of
the drape. Attached to the upper edge of each of the louvers 23 is
a conventional hanger 26 which is adapted to be attached to a
cooperating attaching element depending from each of the carriages
in the conventional traversing support means 27.
By manipulation of conventional control means 50, the drape 15 may
be extended fully across a window opening to assume substantially
the condition illustrated in FIG. 1 in which the louvers 23 are in
spaced parallel relation, with the spacing between adjacent louvers
being at a predetermined maximum for the operation of a particular
traversing support means. Additionally, the panel fabric 16 extends
between adjacent louvers 23 from both the outer and inner edges of
the louvers 23 so that the outer panel sections C are disposed in
coplanar arrangement, with the inner panel sections B also being
coplanar and disposed in parallel relation to the outer panel
sections C. When the drape is arranged as illustrated in FIG. 1,
light and air may pass through the parallel panel sections B and C
to afford maximum light transmission and ventilation.
It will be understood that the drape 15 may be manipulated by
conventional control means 51 to extend the drape or to collapse
it. In the latter position the louvers 23 are disposed in side
stacked relation with the flexible panel sections B and C being
folded, each substantially along a median line. In such condition
the drape occupies a minimum of space along one side of a window
opening to allow the widest possible view.
Each of the louvers 23 is rotatable substantially 180.degree. so
that when the louvers are rotated from the fully open position
illustrated in FIG. 1 to the fully closed position illustrated in
FIG. 3, the edges of adjacent louvers 23 overlap to completely
preclude the transmission of light through the drape. As
illustrated in FIG. 3 in such position only alternate louvers 23
are exposed to view from the rearward side of the drape, there
being alternate sections of panel fabric B exposed to view between
said alternate louvers 23. On the forward side of the drape, as
illustrated in FIG. 4, only the panel fabric is exposed to view.
Preferably, the width of each fabric panel section B or C is
approximately equal to the width of each louver 23 and also
approximates the maximum distance adjacent louvers when in fully
extended condition, as illustrated in FIG. 1.
It will be understood that the louvers 23 may be rotated in either
direction, clockwise or counter clockwise, from a fully open
position and may be arrested at any intermediate position to
regulate the amount of light desired to be transmitted through the
drape.
It will be understood also that conventional sill positioned means
27a substantially identical to the upper traversing support means
27 may be employed to stabilize the lower end of each louver, in a
manner well known in the art.
In the modified embodiment illustrated in FIGS. 5 and 6, the
generally rigid vertically extending louvers are eliminated and
instead a fabric panel 31 having alternate vertical sections of
fine and coarse mesh 32 and 33, respectively is employed, the fine
sections 32 while not generally opaque providing a rather effective
barrier to the transmission of light therethrough. The upper edge
of the panel 31 preferably, is reversely folded and stitched to
form an upper hem 34. Attached to said hem are a plurality of
stiffening members 36, each in registration with a respective fine
mesh section 32. It will be understood that the stiffening members
36 may be permanently or removably attached to the panel.
Preferably, the width of each fine mesh vertical section 32
corresponds substantially to the width of each louver 23 in the
first described embodiment. Also, the width of each coarse mesh
section 32 corresponds substantially to the width of the sections B
and C in the first described embodiment.
The lower edge of the panel 31 is reversely folded and stitched to
provide a lower hem 37. Preferably, a plurality of stiffening
members 38 identical to the members 36 are attached to the lower
hem 37 in vertical registration with the upper members 36. Both the
upper and lower members 36 and 38 are provided with conventional
connecting means 39 for attachment to the carriage assemblies of
the conventional upper and lower support means herinbefore
described.
As in the first described embodiment, the fine mesh sections 32 may
be rotated substantially 180.degree., in both clockwise and counter
clockwise directions. When in open position, as illustrated in FIG.
5, the coarse mesh sections 33 are disposed as shown so as to admit
a maximum of light therethrough. When in closed position the fine
mesh sections 32 are rotated so that the edges thereof, overlap
adjacent fine mesh sections to impede the transmission of light,
exactly as in the first described embodiment.
From the foregoing it will be apparent that I have provided a novel
drape which affords the advantages of vertical louver construction
combined with the esthetic qualities of a conventional drape.
Various changes coming within the spirit of my invention may
suggest themselves to those skilled in the art; hence I do not wish
to be limited to the specific embodiment shown and described or
uses mentioned, but intend the same to be merely exemplary, the
scope of my invention being limited only by the appended
claims.
