12 Claim. (C1. 156—-15)
This invention relates to awnings for windows,
doors, and other ventilating openings of build
ings or vehicles, and more particularly to the
mounting or supporting means therefor.
An object of the invention is to provide an
awning which when mounted is at all times
maintained in fully lowered operative position
under continuous spring tension resisting any
tendency of the awning web to ?ex or collapse.
Another object is to provide an improved
mounting for awnings in which the tensile
strength of the awning web constitutes an im
portant part of the means by which the web
frame is operatively ?xed to the framework
15 forming a part of the window or other opening
10
to which the awning is applied.
A further object is to provide an awning hav
ing a web adapted for detachable connection at
its top to the framework of the Window or other
20 opening and having a base frame detachably
engageable with the framework under positive
spring tension imparted thereto by the act of
attaching the web at its top.
Still another object is to provide a top attach
25 able awning having a base frame inherently ca
pable of maintaining the awning web in a taut,
fully opened state through pressure contact
against a portion of the frame surrounding the
window or other opening with which the awning
.30 is associated.
Other objects and advantages will be apparent
during the course of the following description.
In the accompanying drawings wherein like
characters of reference designate like parts
35 throughout the several views,
Figure 1 is a perspective view of an awning
as mounted on a window frame in accordance
with the invention.
Figure 2 is a perspective view of the base frame
'40 by which the awning web is carried.
Figure 3 is substantially a vertical section
through Figure 1 illustrating in dotted lines the
mounted position of the awning- and in full lines
the manner of mounting the same.

Figure 4 is a perspective view illustrating an
alternative form of base frame.
Figure 5 is substantially a fragmentary verti
cal section through Figure 4 illustrating in full
lines the position of the base frame and web
50 prior to attaching the web at its top and in dot
ted lines the positions assumed‘ by the same
parts following attachment.
Figure 7 is a fragmentary section, partly in
end elevation, of the base frame assembly of
Figure 6.
As shown, the awning is associated with the
frame 8 of a window or other ventilating open 5
ing and comprises a fabric web 9 having along
its top’ edge a series of grommets l0 adapted to
take over headed securing elements ll, prefer
ably of the turn button type, anchored in the
top of the window frame, wherebythe awning 10
web may be detachably secured at its top directly
against the outer top face of the window frame.
At its lower edge the awning web is mounted
over the bight portion of a substantially U-shaped
base frame I2 of durable spring steel wire stock, .
the two arms [3 of which extend in parallel
spaced relation for a distance su?icient to pro
vide the requisite lateral spacing of the bottom
of the awning web from the Window frame. Pref
erably the arms I3 and bight portion 12 occupy ~
a common plane but either or all may be curved
or bowed longitudinally as desired.
The arms I3 have terminalportions l4 bent
at obtuse angles, and in parallelism, the angled
terminals being relatively short in length as
compared to the length of their respective arms.
Aside from the securing elements II, the sole
?ttings for mounting the awning comprise a pair
of screw eyes [5 screwed in the window frame
at each side at the desired horizontal level.
In mounting the awning, the terminal portions
M of the ‘base frame are inserted upwardly in
and through the eyes l5 preferably until arrested
‘by the bend of the arms and the web 9 is then
pulled upwardly and secured over the fasteners -
II. This act of pulling up on the web bows the
spring arms l3 and places the same under a posi
tive tension which constantly urges the arms
downwardly, thus maintaining the web in a taut
state.
It should here be stated that the over-all length
of the web is always too short to permit of its
being fastened at the top without placing the
40
arms l3 of the base frame under tension.
An important feature of the invention resides
in the fact that as the arms 13 are pulled up
wardly under tension, as shown by dotted lines
in Figure 3, their terminal portions M are rocked
inwardly on the fulorums provided by the eyes
l5 and also under tension so that they are forced 1 50
tightly against the window frame. , The pressure
of their, contact against the window frame is so
great that the terminals M are frictionally bound

to the extent which would permit them to drop _.

down through the eyes I5. Thus the base frame
is ?rmly secured in position without the aid of
independent securing elements. The tensile
strength of the web, being greater than the bias
ing force of the spring tension on the arms, thus
constitutes the means by which the base frame
is operatively ?xed in relation to the window
frame.
_
In the ‘embodiment shown in Figures 4 and 5
10 all parts are identical to the form previously
described except that the use of eyes on the
window frame is dispensed with and the terminal
portions M’ of the spring arms l3 are continued
in the axis of their respective arms, being re
15 ceived in sockets l5’ bored or otherwise provided
in or on the window frame at each ‘side thereof.
In this embodiment, as the web 9 is pulled up to
fasten it at its top, the spring arms l3 are bowed
upwardly under tension so that the web is main
20 tained taut and the tension of the terminal por
tions l4’ against the walls of the sockets I5’ is
greatenough to preclude the possibility of acci
dental
dislodgment.
‘
__
The embodiment illustrated in Figures 6 and '7
25 is identical with the form shown in the preced
ing views except that the substantially U-shaped
base frame consists of a bight portion Hiv and
arms ll formed of pipe lengths joined by elbows
l8. Lengths of spring steel wire I 3 are inserted
30 axially in the ends of the arms I‘! and may be
adjusted therein by means of set screws V2!] to
provide for rigidity of the assembly and for varia
tion in the space of the bight portion l6 laterally
from the window frame. The inner end portions
35
2| of the wire lengths l9 are obtusely angled so
that they may be passed upwardly through the
eyes l5 when mounting the awning as in the man
ner of the terminals ll! of the spring arms l3
embodied in the form. of invention shown in Fig
40 ures 1 to 3.
.
In this embodiment, when the web 9 is pulled
upwardly to be fastened at its top, the major ten
sion of the spring vwire lengths l9 occurs in their
terminal portions 2| which rock on the fulcrums
45
provided by the eyes l5 and bear tightly against
the face of the window frame with a pressure
sufficiently great to preclude the possibility of ac
cidental dislodgment by dropping down through
the
50
eyes.
The tension constantly ’ urges the
lengths l9 downwardly and thus maintains the
web in a taut condition or state.
In all embodiments of the invention it is the
upward pull on the awning in attaching it at its
top to the window frame that places the spring
means under tension and the tension thus im
65 parted is maintained constant until the web is
detached, resulting in a constant bias on the awn.
ing web by which it is kept taut and restrained
against ?exing or collapse.
The determining factor which assures proper
60 tension of the spring means effecting tautness
of the awning web and anchorage of the base
frame to the window or other opening frame is,
in all embodiments of the invention, the fact
65 that prior to the connection of the web to the
upper part of the window frame the straight line
distance between the horizontal plane of that
point of connection and the bight‘ of the U-shaped
base frame is greater than‘ the all-over length of
70 ‘the web so that the web must be pulled up to ef
fect its connection, thereby placing the resilient
angle of their terminal portions. As the angle is
increased the tension will be greater and vice
versa.
The screw eyes l5 and the sockets l5’ comprise
guide and retaining sockets detachably receiving
the terminal portions of the base frame arms.
However, it is within the province of this inven
tion that the retaining or securing means may
take other forms. If found desirable or expedient
the terminal portions of the base frame ‘arms may 10
be ?xedly secured to the window frame or other
supporting structure. The structural arrange
ment of the base frame and its resilient arms may
also be varied. It is, therefore, to be understood
that within the limits imposed by the scope of 15
the invention as claimed the structure may be
varied as desired.
