Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to completely self-storing awnings, and more
particularly to an awning and frame which remains on the building
all year, and in which the fabric awning is completely concealable
and protected by the hood of the frame when not in use, thus
eliminating the labor and expense of yearly put up, take down, and
storage.
2. Description of the Prior Art
Applicants are not aware of any prior constructions of self-storing
awnings excepting one previously made by their assignee, The Astrup
Company, which did not disclose the features of their self-storing
awning frame hereinafter described and claimed.
SUMMARY OF THE INVENTION
The invention may be briefly described as a self-storing awning for
windows and the like, including an elongated hood for mounting
above a window or the like. The hood is entirely closed upon its
top and back. The forward edge of its bottom wall is spaced
inwardly from the front of the hood. The front wall of the hood
terminates at a point spaced above the bottom wall.
End brackets close opposite ends of the hood. A roller is
journalled in these end brackets upon ball bearings or the like. At
one end of the roller is formed a spool upon which an operating
rope is coiled.
A flexible awning is rolled upon the roller, having one edge
attached thereto by any suitable means, the other edge of the
awning extending through the opening in the hood between the lower
edge of the front wall and the forward edge of the bottom wall
thereof.
This other edge of the awning is attached to a front bar carried by
a pair of spaced awning arms, the lower or inner ends of which are
hingedly connected to the wall of the building at opposite sides of
the window. Spring means is provided for swinging the arms
outwardly and downwardly upon the hinge joints, so as to keep the
awning under tension at all times.
The operating rope extends downwardly from the spool, through a
rope guide at the adjacent end of the hood, and is adapted to be
attached to a rope cleat of conventional design upon this side of
the building for holding the awning in adjusted position.
The parts are so constructed and arranged that when the awning is
entirely rolled up upon the roller for self-storing as in winter,
the front bar will be completely received within the hood so as to
completely conceal and protect the fabric awning during winter
storage or inclement weather.
It is an object of the invention to provide a self-storing awning
including an elongated hood with means for mounting the same above
a window or the like, the hood having an opening at its lower front
corner, a roller journalled in said hood, a flexible awning having
one edge portion connected to the roller, the other edge portion
thereof extending through the opening in the hood, and means for
extending the awning downwardly and outwardly from the hood to any
desired adjustment or for rolling the awning entirely upon the
roller so that it is completely concealed and protected around the
hood.
Another object of the invention is to provide such a self-storing
awning in which a front bar is attached to the outer edge of the
awning and is adapted to be received through the opening in the
front lower corner of the hood when the awning is not in use.
A further object of the invention is to provide a self-storing
awning of this type in which the front bar is carried by a spaced
pair of awning arms hingedly connected at their rear ends to the
building on opposite sides of the window.
A still further object of the invention is to provide such a
self-storing awning in which spring means urges the arms outward
and downward so as to always keep the flexible awning taut.
Another object of the invention is to provide a self-storing awning
of the character referred to in which the flexible awning may be
rolled up to any desired adjustment by rope means upon the
roller.
A further object of the invention is the horizontal adjustability
of the awning arms on the front bar, allowing easy placement on the
building.
A still further object of the invention is the provision of hanger
brackets designed to allow placement on the building studs, and
also allow the hood to be centered after the brackets are
installed.
The above objects together with others which will be apparent from
the drawings and following description, or which may be later
referred to, may be attained by constructing the improved
self-storing awning, in the manner hereinafter described in detail
and illustrated in the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Reference is now made more particularly to the embodiment of the
invention illustrated in which similar numerals refer to similar
parts throughout. The frame for the self-storing awning comprises
the hood indicated generally at 1, the hanger brackets 2 therefor,
the roller 3 journalled within the hood, the front bar indicated
generally at 4, the awning arms 5, the spring loaded hinges
therefor indicated generally at 6; and the flexible awning 7
attached at one end to the roller 3 as by a piece of double
adhesive tape, and at its other end to the front bar 4.
The front bar 4 as best shown in FIGS. 1, 2 and 4 may be an
extruded structural member having a substantially horizontal bottom
wall with central longitudinal slots 70 therein, substantially
vertical side walls extending about halfway from the bottom to the
top and inwardly upwardly disposed angular walls extending from
this point to the top, the upper edges of said angular walls being
slightly separated to form a longitudinal groove. As best seen in
the FIGS. referred to, the cross-sectional shape of this front bar
resembles generally a triangle superimposed upon a rectangle.
The hood 1 is formed of two aluminum members, namely, the rear hood
8 and the front hood 9, both of which may be in the form of
extrusions. The rear hood 8 forms the back wall 10, the bottom wall
11 and approximately half of the top wall 12 of the hood, while the
front hood 9 forms the abbreviated front wall 13 and the other half
14 of the top wall of the hood.
Upper and lower longitudinal ribs 15 and 16 respectively are formed
upon the hood 1 adjacent the back wall 10 thereof. Each of the
brackets 2 has an outwardly disposed, substantially horizontal
lower flange 17 with screw threaded aperture 18 therein and a
forwardly and downwardly disposed upper flange 19. Apertures 20 are
formed in each bracket 2 for attaching the same to a wall or the
like as indicated at 21 as by screws 22.
To mount the hood 1 above a window or the like, the brackets 2 are
attached at building studs in the wall or top of the window frame
by the screws 22 and the upper rib 15 of the hood is inserted
beneath the upper flanges 19 of the brackets while the lower rib 16
is seated upon the horizontal lower flange 17 thereof. The hood 1
may be centered on the window after the brackets are installed.
A screw 23 is located through the threaded aperture 18 of each
lower flange and engaged with the bottom wall of the hood to hold
the same rigidly in position upon the brackets. The forward edge of
the top wall portion 12 of the rear hood 8 is bent upwardly and
backwardly, forming the hooked edge 24, and the rear portion of the
top wall of the front hood 9 is offset upwardly as at 25 and then
bent downwardly and forwardly, forming the hooked rear edge 26
which interlocks with the hooked front edge 24 of the rear hood.
The forward edge of the bottom wall 11 is bent downwardly and
backwardly forming the rearwardly hooked front edge 27.
An outwardly disposed horizontal flange 28 is formed at the lower
edge of the abbreviated front wall 13 of the hood and terminates in
the upwardly disposed reinforcing flange 29. A rope guide,
indicated generally at 30, is located at each end of the hood 1.
Each rope guide is of angular shape comprising the front vertical
portion 31 and the lower horizontal portion 32.
An outwardly disposed horizontal flange 33 is formed at the upper
edge of the front vertical portion 31 and terminates in a
downwardly turned reinforcing flange 34. A screw 35 connects the
flange 33 of each rope guide 30 to the flange 28 of the front wall
13. The rear edge of the lower horizontal portion 32 of each rope
guide 30 is downwardly offset as at 36 and upwardly and forwardly
bent forming the forwardly hooked edge 37 which is interlocked with
the rearwardly hooked edge 27 of the bottom wall 11.
A grommet 38 is located in the lower horizontal portion 32 of each
rope guide. Although the rope is located at only one end of the
roller 3, the rope guides 30 are located at opposite ends of the
hood for connecting the edges of the abbreviated front wall 13 and
bottom wall 11 so that the same item may be used at each end of the
hood.
The ends of the hood are closed by end brackets 39, each of which
is rectangular in shape and provided with inturned flanges 40 at
its top, bottom and side edges. An end plate 41 has an angular
flange 42 at its outer end connected to the adjacent end bracket 39
by bolt and nut 43 and 44 respectively.
The flanges 40 at the top, bottom and front edges of the end
brackets 39 are located within the corresponding walls of the hood
while the flange 40 at the rear edge of the end bracket is located
outside of the back wall 10 of the hood. Screws 45 connect the
bottom wall 11, top wall 12 and front wall 13 of the hood to the
corresponding flanges 40.
A spool 46 is located on one end of the roller 3, and an operating
rope 47 has one end connected to the spool by any conventional
means, the rope being coiled upon the spool and the other end
thereof being threaded through the rope guide grommet 38 and
attached to a conventional rope cleat 47' as shown in FIG. 2. A
rope stop 47.sup.a if fixed upon the rope 47 to prevent the awning
from unrolling beyond the desired projection.
The lower end of each awning arm 5 has a hinge attachment,
indicated generally at 48, connected thereto. This attachment
comprises the cup portion 49, into which the lower end of the
awning arm 5 may be received and fixed therein by any conventional
means, and an ear 50 having an aperture 51 therein.
The ear 50 is received between the spaced ears 52 upon the hinge
bracket 53. A hinge pin 54 is located through the apertures 55 in
the bracket ears 50 and the aperture 51 in the hinge attachment 48.
The hinge brackets 53 are attached to the sides of the window frame
or to the wall, at each side of the window as by screws 56.
An arm spring, indicated generally at 57, is associated with the
hinge joint of each awning arm 5. Each arm spring includes the
spring arms 58, each having a hooked upper end 59 which engages the
rear or inner side of the corresponding awning arm 5. The spring
arms 58 converge upwardly from the outer ends of the coils 60 which
are located around opposite end portions of the hinge pin 54
between the hinge bracket ears 52 and the washers 61 on the hinge
pin.
One washer 61 is stopped by the head 62 of the hinge pin and the
other washer by the cotter pin 63. The inner ends of the spring
coils 60 are joined by an upwardly and rearwardly disposed U-shaped
portion 64 of the spring, the closed end of which contacts the
upper edges of the ears 52 on the hinge bracket 53.
Each of the awning arms 5 is preferably an aluminum tube, to the
upper end of which is connected an adapter 65, preferably of
hexagonal shape. The adapter has a depending, rounded shank 66
received in the upper open end of the tubular awning arm 5. A
carriage bolt 67 is threaded into the upper end of the adapter 65
and is located through a central aperture 68 in the arm adjusting
channel 69.
The upper end of the bolt 67 is received in the longitudinal slot
70 in the extruded front bar 4, the head 71 of the bolt overlaying
the side edges of the slot 70. When the bolt 67 is tightened it
draws the upper edges of the channel member 69 into the
longitudinal grooves 72 in the front bar 4. The upper ends of the
awning arms 5 may be adjusted longitudinally of the front bar 4 to
desired position and the bolts 67 tightened to hold them in
adjusted position. This horizontal adjustability of the awning arms
5 upon the front bar 4 allows easy placement of the awning on a
building.
A longitudinal groove 73, of circular cross-section, is formed in
the top of the front bar 5, as best shown in FIG. 4, to receive the
outer edge of the flexible awning 7, which is formed into a tubular
casing as indicated at 74. A rope 75 is located within the tubular
casing 74, whereby the rope filled casing may be longitudinally
slidably received in the rounded groove 73 in order to attach the
front bar to the front edge of the awning 7.
The ends of the roller 3 are journalled upon the end brackets 39 as
best shown in FIG. 6. An aluminum rivet 76 is located through a
central aperture 77 in the end bracket 39. A plastic bushing 78 is
located around the rivet 76 and within a hollow trunnion 79. The
inner race 80 of a flanged ball bearing is mounted upon the hollow
trunnion 79 and the outer race 81 of the ball bearing is located
within the end of the hollow roller 3.
All parts of the improved awning frame are preferably constructed
of aluminum excepting the awning arm springs 57, the plastic
bushings 78 and the ball bearings 80-81, in order that it will not
rust in any kind of weather.
OPERATION
The improved self-storing awning eliminates winter storage expense
as it remains on the building throughout the entire year. The
awning arm springs 57 urge the awning arms 5 outward and downward
as far as the adjustment of the awning rope 47 will permit. By
loosening the awning rope 47 sufficiently, the awning 7 can be
lowered to below center position for added protection to carpets,
drapes and other interior furnishings from damaging sun rays even
on bright winter days.
By manipulation of the awning rope 47, the awning may be easily
rolled up to let in light on dark dreary days. When completely
rolled up for winter storage, or protection against heavy rain, the
fabric awning 7 is completely concealed and protected within the
aluminum hood, as shown in FIG. 4.
The horizontal adjustment of the awning arms upon the front bar 4
allows easy alignment of the awning frame on a building. The awning
fabric will have long life because there are no ropes to wear on
the fabric awning as in conventional awnings.
After the awning has been stored for the winter, as shown in FIG.
4, no labor or expense is required for putting up the awning in the
spring or summer. All that is necessary is that the awning rope 47
be untied from the the cleat 47' and the arm springs 57 permitted
to swing the awning arms 5 outwardly and downwardly to the desired
position when the awning rope may again be tied upon the cleat 47'
and the awning is ready for use.
Instead of placing the hood 1 on the building face as shown in the
drawings, the hood may be inverted and placed on an overhang at a
window.
