MOBILE HOME AWNING

Abrégé anglais

ABSTRACT OF THE DISCLOSURE
A demountable awning for recreational vehicles
fabricated of two layers of air impermeable material. A leading
a leading edge of the awning is secured to the vehicle and a
trailing edge is supported by poles. The edges of the material
are sealed and at least one gutter extends from the leading edge
to the trailing edge so as to divide the awning into two or more
separate airtight compartments, each having air inlet means.
The gutter is formed by sealing the two layers together so as to
provide a gutter of sufficient width to be relatively unclogable.

Revendications

The embodiments of the invention in which an exclusive property
or privilege is claimed are defined as follows:
1. A demountable awning for use on recreational vehicles, said
awning comprising an upper and a lower layer of flexible air impermeable
material, said layers of material being sealed at their edges so as to be
air tight, a leading edge of said awning being provided with means to secure
said awning to a side wall of said vehicle, a trailing edge of said awning
being provided with spaced apart reinforcing rings adapted to receive upper
ends of supporting poles and at least one gutter extending from said leading
edge to said trailing edge, each said gutter being formed by sealing said
upper and lower layers together thereby providing an air chamber on each
side of said gutter and spaced apart by said gutter, each said air chamber
being provided with a sealable tube to permit inflow and outflow of air.
2. An awning as claimed in claim 1 wherein the flexible material
is vinyl heat sealed at the edges and along said gutters.
3. An awning as claimed in claim 1 wherein tabs are provided
along and extended from said trailing edge and are provided with said
reinforcing rings.
4. An awning as claimed in claim 1 wherein the flexible material

fabric.

Description

~q.~8~
This invention relates to portable shelters and more particularly
to a demountable awning for recreational vehicles such as trailers capable
of being rol led up and stored therein when not in use.
The awnings presently in use are fabricated of canvas or synthetic
cloth coated with a waterproof plastic. A leading edge of the awning is
removably secured to the wall of the trailer or the like and the trailing edge
is supported by poles and guy ropes so as to provide the desired slope.
The disadvantage of such an awning is that during a rainstorm
rainwater tends to collect adjacent the trailing edge and if allowed to accum~-
10 i ~ late cauSes the awning to sag. It is therefore advisable for the occupant togo out in the rain to tip the water out of the awning. I F this is not done
the awning will probably develop a permanent bulge and its replacement will
be i ndi c at ed .
One of the solutions devised by the campers havirig such awning
Is that of supporting the awning with sheets of plywood. However, removing
the plywood sheets and storing them in the trailer when travelling is awkward
and Inconvenient.
The present invention is designed to overcome the disadvantages
described above by the provision of an inflatable awning having a plurality
20 of convex air chambers. Rain therefore tends to col lect in the narrower
gutter rather than along the leading edge of the awning. Furthermore the
awnlng is more rigid than those commonly in use due to the provision oF the
alr chamber.
It is therefore an object of this invention to provide an inflatable
aWning adapted to prevent build up of rainwater in amounts capable of
causlng sagging oF the awning.
A further advantage of the present invention is that it can be
Polded or rolled for storage or travel.
A stlll further object is the provision of an awning requiring no
30 addltional metal braces or rigid stiffening means.
Accordingly the present invention provides a demountable awning
for use on recreational vehicles, the awning comprising an upper and a lower
layer of flexible air impermeable material, said layers of material being
sealed at theiredges so as to be air tight, a leading edge of the awning

~ eing provided with means to secure the awning to a side wall of the
vehicle, a trailing edge of said awning being prov7ded with spaced apart
reinforcing rings adapted to receive upper ends of supportin9 poles and at
least one gUtter extending from said leading edge to the trailing edge, each
gutter being formed by sealing the upper and lower layers together thereby
providing an air chamber on the side of the gutter and spaced apart by the
gutter, each air chamber being provided with a sealable tube to permit inflow
and outflow of air.
In the drawings which illustrate embodiments of the invention
Figure 1 is a perspective view of the awning of this invention
; in position on the house trai ler,
Figure 2 is a top plan view of the awning of Figure 1,
Figure 3 is an end elevational view of the awning of Figure 2
and
Figure 4 is a part sectional side elevatjonal view of the
, attaching means on the awning and the mating portion on the trai ler.
` Referring now in detai I to the drawings in Figure 1 the awning
10 is shown in position on a trailer 12. As shown more clearly in Figure
3 the awning 10 comprises an upper layer 14 and a lower layer 16 of
flexible air impermeable material in this case a suitable plastic such as
vinyl. The lower layer 16 may also comprise vinyl coated polyester fabric.
The upper and lower layers are preferably heat sealed along a leading edge
20, a trailing edge 22 and both side edges 24. Further lines of heat sealing
28 define gutters 30 and 32 which divide the awning 10 into three air
chambers 33, 34 and 36. It will be appreciated that this is an example and
that the number of chambers may be varied to suit the size of the awning or
t other considerations.
Each of the chambers 33, 34 and 36 is provided with an air inlet
. tube 38 having a suitable plug or cap. The tubes 38 are conveniently
arranged adjacent the trailing edge 22 of the awning so they can be reached
to blow air into the chambers using an air pump or the like.
A number of tabs 40, in this case four, are provided on each
of the trailing edge of the awning 10. The tabs 40 extend beyond the
trailing edge 22 and each has an aperture therein provided with a reinforcing
2-

7~
"_ ing 42 to receive an end of one of the supporting poles 46 7n a conven-
tional manner,
The leading edge of the awning is folded over and fastened so as
to receive and retain a rope 50. As shown more clearly in Figure 4 the
leading edge 20 of the awning 10 is slid into a channel member 52 which is
in turn secured to a wall 54 of the trailer 12 by screws 56.
In use the awning is secured to the side of the trailer as
described above and the supporting poles and guy ropes are positioned in
the usual manner. Before and after erecting the awning, however, the
10 chambers 33, 34 and 36 are inflated. When inflated the chambers provide
some resistance to bending along their lengths and the curved upper portions
tend to direct rain into the gutters 30 and 32 thus discouraging bui Id up of
water adjacent the trai ling edge of the awning 10. In addition the gutters
30 and 32 having been made sufficiently wide thus making it less likely
that leaves~ pine needles and the like will be trapped in them and restrict
run off of the rainwater.
