GUTTER GUARD
FIELD OF THE INVENTION
The present invention relates to an eavestrough or rain gutter and more particularly,
relates to improvement in such structures.
BACKGROUND OF THE INVENTION
Various types of gutters or eavestroughs are well known in the art as is the use of
shields or gutter guards therewith. The purpose of the gutter guard is essentially to permit
passage of rainwater from the roof to the eavestrough while protecting the same from
extraneous foreign matter such as leaves and the like.
The art has taken many different approaches to the design of eavestroughs which
utilize such gutter guards. Indeed, in order to prevent the use of such gutter guards, a
commercially available eavestrough utilizes a device on the roof eave which has an outer
edge which curls downwardly and the water flow follows the curved portion due to surface
tension and thereafter cascades into the eavestroughs. Leaves and other extraneous matter
are supposed to fall exteriorly of the eavestroughs. However, when a large volume of water
flows, the surface tension is generally insufficient to direct all the water to flow into the
eavestroughs.
The art is also replete with examples of different types of gutter guards which
constitute a physical barrier across the top of the eavestrough with apertures formed therein
to permit the passage of rainwater while supposedly barring the passage of extraneous
material. However, the connection of the gutter guard to the eavestrough is often a time
consuming step and accordingly not always well accepted in the art.
In order to overcome the above disadvantages, there have also been proposals in the
art for the fabrication of one piece eavestroughs which are secured to clips fastened under the
roof shingles. One such arrangement is shown in U.S. 4,727,689 to Bosler. Problems
associated with this particular design is that in some instances, depending on overhangs and
the like, one cannot attach the clips in the desired position. Furthermore, snow loads as are
frequently encountered in Northern climates, could cause the gutter to fall from its mounting
arrangement with the clip.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an integrated eavestrough and gutter
guard and which integrated eavestrough overcomes the disadvantages of the prior art.
According to one aspect of the present invention, there is provided an eavestrough
formed from a single piece of material, the eavestrough comprising, a rear wall, a front wall,
a bottom wall extending between the rear wall and the front wall, the rear, front and bottom
walls defining a trough therebetween, a perforated top wall extending between the rear wall
and front wall over the trough, and the top wall engaging a rear surface of the rear wall in a
locking relationship.
According to a further aspect of the present invention, in a building structure having
an eavestrough, the improvement comprising an eavestrough formed from a single piece of
material, the eavestrough comprising a rear wall, a front wall, a bottom wall extending
between the rear wall and front wall, the rear, front and bottom walls defining a trough
therebetween, a perforated top wall extending between the rear wall and the front wall over
the trough, and the top wall engaging a rear surface of the rear wall in a locking relationship.
The one piece eavestrough of the present invention may be formed from any suitable
material with a preferred material being aluminum. The eavestrough may be manufactured
using roll forming techniques.
As previously mentioned, the eavestrough of the present invention prevents foreign
matter from entering therein. In order to do so, there are provided a plurality of apertures to
permit the passage of rainwater while preventing extraneous matter from entering the
eavestrough. In general, it is desirable that the apertures be sized large enough to permit
passage of rainwater while preventing the entry of extraneous material into the trough.
Generally, apertures having a range of between 3 and 4 mm. in diameter have been found to
be suitable.
The eavestrough of the present invention is known in the art as a half round
eavestrough as the bottom portion has a rounded configuration. Preferably, the eavestrough
is connected to the adjacent building structure by fastening members such as screws. While
this arrangement functions well from the support point of view, the aesthetic appearance is
not always what could be desired. Accordingly, the eavestrough of the present invention
provides for the use of decorative members which may be secured thereto to provide the
appearance of an eavestrough which is supported by a bracket or the like.
The decorative members secured to the eavestrough may be of any design or
configuration desired. As aforementioned one particular design is intended to give the
impression that the eavestrough is supported by brackets. Such brackets may in turn carry
various decorative effects.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings in a greater detail and by reference characters thereto, there
is illustrated in the drawings an eavestrough which is generally designated by reference
numeral 10.
Eavestrough 10 is comprised of a rear wall 12, a rounded bottom wall 14, and a front
wall 16. A top wall extends across the trough 17 which is defined by walls 12, 14 and 16.
Top wall 18 includes a plurality of apertures 20 formed therein.
As may be seen in Figure 2, rear wall 12 includes an upper recess 22 and a lower
recess 15 for purposes which will be discussed hereinbelow. Also, as may be seen in Figure
2, between front wall 16 and top wall 18, there is provided a nose generally designated by
reference numeral 24.
Nose 24 has a first semispherical portion 26 extending outwardly from front wall 16
and there is provided a groove 28 in an upper portion thereof.
From nose 24, there is provided a vertical wall 30 which functions to prevent
overflow of water from the top wall 18 during periods of heavy rain. Similarly, at the other
side of top wall 18, there is provided a retaining wall 32 which has a first vertical portion 34
and a rearwardly directed portion 36.
From rearwardly directed section 36, there is provided a downwardly extending
section 38 which terminates in an inwardly extending locking segment 40. As may be seen
in Figure 3, locking segment 40 is designed to engage recess 22 to maintain the eavestrough
10 in an assembled condition. The eavestrough can then be attached by means of fastening
members 33 passing through wall section 34, the upper portion of rear wall 12, and
downwardly extending section 38.
As previously mentioned, the eavestrough 10 is designed to be used with a plurality of
decorative members 42. Each member 42 has a rounded body portion 44 configured to
match that of rounded bottom wall 12 and front wall 16. Member 42 is also provided with a
nose section 46 at either end thereof, with inwardly extending locking segments 48 and 50.
Locking segments 48 and 50 are designed to engaged recesses 15 and 28 respectively.
