EAVESTROUGH COVER
FIELD OF THE INVENTION
The present invention relates to a cover for an eavestrough.
BACKGROUND OF THE INVENTION
The use of covers for gutters or eavestroughs is well known in the art and
there have
been many proposals for different types of covers. The purpose of the cover is
essentially to
permit the passage of rainwater from the roof to the eavestrough while
protecting the same
from extraneous foreign matters such as leaves, twigs and the like.
There have been several different approaches which have been proposed in the
prior
art with respect to the design of covers. A first approach which is widely
used is a cover
which is foraminous and permits passage of rainwater while attempting to bar
the passage of
extraneous matter. There are many different designs with some of these not
functioning as
well as might be desired. In order to overcome problems, it has also been
proposed that the
eavestrough itself be mounted for pivotal movement such that it may be emptied
at desired
intervals.
A still further approach which has been taken is utilizing a design wherein a
cover
has an outer edge which fills downwardly and the water follows a curved
portion due to
surface tension and thereafter cascades into the eavestrough. While this
structure works
under certain conditions, when the volume of water becomes sufficiently large,
the surface
tension is insufficient to direct all the water into the eavestrough.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a cover for an eavestrough
which
can handle relatively high flows of water while preventing the entry of
extraneous material.

According to one aspect of the present invention, there is provided a cover
for an
eavestrough comprising a first side structure and a second side structure, a
central planar
portion intermediate the first side structure and the second side structure,
the central portion
having a plurality of longitudinally extending sections, each of the
longitudinally extending
sections being separated from each other by a rollback member, each of the
rollback
members extending longitudinally and having one face thereof of a C-shaped
configuration,
each of the faces having a C-shaped configuration facing the same direction
towards the
second side structure, and each of the longitudinally extending sections
having a plurality of
apertures formed therein.
According to a further aspect of the present invention, there is also provided
in
combination, an eavestrough having a rear wall, a bottom wall, a front wall,
and an inwardly
extending top wall section joining the front wall, and a cover for the
eavestrough, the cover
comprising a first side structure and a second side structure, a central
planar portion
intermediate the first side structure and the second side structure, the
central portion having
a plurality of longitudinally extending sections, each of the longitudinally
extending sections
being separated from each other by a rollback member, each of the rollback
members
extending longitudinally and having one face thereof of a C-shaped
configuration, each of
the faces having a C-shaped configuration facing the same direction towards
the second side
structure, and each of the longitudinally extending sections having a
plurality of apertures
formed therein.
The cover of the present invention utilizes a plurality of "rollbacks" which
are
structures designed to redirect the flow of water to prevent overflow of the
eavestrough.
These rollbacks extend longitudinally of the cover and prevent a rush of water
from running
_ 2 _

CA 02783834 2012-07-26
to the side and then overflowing.
The device of the present invention may be formed of any suitable material and
is
conveniently formed either of metallic or plastic material. As is known in the
art, metallic
materials such as aluminum may conveniently be used. However, it is within the
scope of
the present invention for one to use other materials and they may either be
similar or
dissimilar.
The device of the present invention prevents foreign matter from entering into
the
eavestrough. In order to do so, there are provided a plurality of apertures to
permit the
passage of rainwater through the cover while still preventing extraneous
matter from
entering the eavestrough. Sizing of the apertures is well known in the art and
generally they
will have a size of between 2.5 and 10 mm.
The first side structure may be adjacent the front wall of an eavestrough and
may be
secured to a top wall of a K type eavestrough. The cover is also provided with
a channel
adjacent to the front wall of the eavestrough. The channel is defined by a
pair of walls and
at the bottom of which, there is provided an opening to aid in drainage of the
water. The
second side structure will preferably include a sealing strip which is
retained by the second
side structure. The sealing strip is preferably of a flexible material and is
designed to abut
the eaves to prevent water from going between the second side structure and
the cave.
The number of rollbacks formed in the cover may vary. Any number between two
and six are preferred. Each rollback preferably extends a height above the
planar portions of
between 1 mm and 6 mm.
BRIEF DESCRIPTION OF THE DRAWINGS

accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a perspective view of a cover for an eavestrough according to one
embodiment of the present invention;
Figure 2 is an end elevational view thereof; and
Figure 3 is a sectional view illustrating placement of the cover on an
eavestrough.
DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings in greater detail and by reference characters
thereto, there
is illustrated in Figure 1 a cover generally designated by reference numeral
10 which can be
utilized with a conventional K type eavestrough. Naturally, it can also be
utilized with
other types of eavestrough with or without modifications.
Cover 10 includes a first side structure generally designated by reference
numeral 12
and a second side structure generally designated by reference numeral 14.
Intermediate first
side structure 12 and second side structure 14 is a central portion generally
designated by
reference numeral 16.
Central portion 16 includes a plurality of longitudinally extending sections
18, 20, 22
and 24. Each of sections 18, 20, 22 and 24 has apertures 26 therein to permit
the passage of
water therethrough. Separating the longitudinally extending sections 18, 20,
22 and 24 are
rollbacks 28, 30, 32 and 34. Each rollback has a substantially identical
configuration and
thus only one will be described herein. Rollback 28 has a wall 36 having a C-
shaped or
concave configuration. Rollback 28 also includes a second back wall 38. It
will be noted
that there are provided apertures 40 in wall 36.
Adjacent first side structure 12 is a trough 42 defined by first trough wall
44 and a
second trough wall 46. Again, it will be seen that apertures 47 are provided
at the bottom of

trough 42. A flange 48 extends outwardly from second trough wall 46. Flange 48
includes
a doubled under segment 50. Flange 48 is designed to be secured to the
eavestrough by
suitable mechanical fasteners.
Second side structure 14 includes a doubled back segment 52 which then merges
with
an upwardly extending wall 54 and a downwardly extending wall 56. The
structure
terminates with an upwardly extending wall 58. A sealing strip 60 is retained
between
downwardly extending wall 56 and upwardly extending wall 58.
The provision of rollbacks 28, 30, 32, and 34 assist in preventing the
overflow of
excess water over the edge and which would tend to stain the front wall of the
eavestrough.
As may be seen in Figure 3, cover 10 is installed on an eavestrough having a
rear
wall 80, a bottom wall 82, a front wall 84 and a top wall segment 86. Flange
48 is secured
to top wall segment 86 by means of mechanical fasteners (screws) 88. The
eavestrough may
be supported by a hanger shown in dash dot lines. A screw 90 may extend
through wall 58
and the hanger into an adjoining eave.
