The present invention relates to a cover for an eavestrough.
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.
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 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 eave.
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.
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:
Referring to the drawings in greater detail and by reference characters thereto, there is illustrated in
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
It will be understood that the above described embodiment is for purposes of illustration only and changes and modifications may be made thereto without departing from the spirit and scope of the invention.
