This invention relates to barriers for rain gutters and similar structures for keeping leaves and other debris out of the rain gutters. More particularly, this invention relates to rain gutter debris preclusion barriers, which utilize a conformed screen to allow water to pass into the gutter, but preclude debris from passing through the screen and into the gutter.
Prior art gutter debris preclusion devices are known to have difficulty in addressing excessive flow of rainwater coming off the roof of a house into the gutter. With excessive water flow, debris often accumulates on the device, clogging or impeding the effectiveness of the devise. Many complicated designs have been contemplated by others in the industry, each with their advantages and disadvantages. Of particular difficulty, is the need to support the “guard” over the gutter, wherein complicated and diverse support and bridging systems have been devised. These support systems add to the complexity, weight, and most importantly the cost of these guards. The industry was in need of a new system to support the guard over the gutter with easy installation, little or no increased weight, and without increasing the cost of the guard.
The present invention overcomes the deficiencies in the art by creating various systems and devices of screened gutter debris preclusion.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
Various embodiments describe a covering that goes over a roof gutter for the purpose of keeping leaves, pine needles and small debris out of the gutter and for allowing rainwater to pass through a permeable material and into the gutter.

In the various embodiments described herein, the mesh's corrugations 112 can be patterned to be rectangular, square, of various shapes, etc., and oriented substantial orthogonal (perpendicular) to the orientation of the lip of the gutter. The perpendicular orientation provides for linear or planar stiffness along the roof-togutter lip line, resulting in a self-supporting mesh. The mesh's corrugations can be formed from stamping the mesh, pressing the mesh, or weaving the mesh in a corrugated form, and so forth.
The connectors 115 and 125 are similar to the lower and upper strips described in published application US 20110056145, published on Mar. 10, 2011, which is incorporated herein by reference in its entirety.
The corrugations 112 formed in the mesh 135 are formed similar to the corrugations formed in the mesh in published application US 20110056145, published on Mar. 10, 2011, which is incorporated herein by reference in its entirety.
The mesh 135 provides the function of allowing water to pass into the gutter while precluding debris from passing into the gutter. This corrugated mesh 135 is preferably formed as a woven screen of stainless steel wire or other wire-thread of suitable material. Important characteristics of the material forming the mesh include sufficiently high strength and inelasticity to function structurally, as well as resistance to corrosion in the gutter environment. Furthermore, it is advantageous that material forming the corrugated mesh 135 can be readily bent sufficient to cause the material to be readily corrugated into one of a variety of different cross-sections and hold that configuration after being so bent. Most preferably, the wire forming the corrugated mesh 135 extends in a pattern with some threads extending parallel with an upper edge (extending substantially parallel to the roof, when in use) of the overall corrugated mesh 135 and some of the wire/thread extending perpendicular to the upper edge. In such a configuration, the corrugation can occur to create the crests and valleys with only the threads, which run parallel with the upper edge needing to be bent. In such a configuration the corrugating of the fine mesh material forming the corrugated mesh 135 can more readily occur and this material formulating the corrugated mesh can more readily maintain this corrugated configuration during installation and use.
The corrugations 112 in the corrugated mesh 135 preferably have an amplitude between crests and valleys between one-fourth and one-tenth of the length of the corrugated mesh 135 between the upper edge and a lower edge (extending substantially parallel to the gutter lip when in use) of the mesh 135 and similar to a width of the opening in the gutter. Preferably, the corrugations 112 are in a repeating pattern. This pattern is most preferably a sinusoidal pattern with a curving crest and curving valley. Other configurations can also be provided for the corrugated mesh 135.
It should be apparent that the mesh may be of any material that is weather resistant, has apertures for drainage, and is of sufficient stiffness to bridge the gutter without the need for an auxiliary support. Therefore, the gutter cover can be constructed of other materials such as plastic, expanded metal, perforated metal, slotted metal or louvered metal slits, and so forth. Furthermore, the mesh, with its associated corrugations does not need to completely span the gutter. That is, the mesh's corrugations can be limited to certain portions, according to design preference, and may not need span the entirety of the gutter. For example, the trough may be corrugation free. It should also be apparent that the front strip connector and the rear strip connector can be formed from metal, plastic, or any other suitable material. As a matter of convention, the front strip connector may alternately be referred to as a gutter lip rail that is connected to the gutter lip side of the mesh, and the rear strip connector alternately referred to as a roof side rail that is connected to the roof side of the mesh.
It is understood that in various other embodiments, the trough 145 (shown in the various embodiments as adjacent to the front strip connector and parallel to the longitudinal axis), can be angled to the front strip connector as well as be oriented at an angle to the mesh's corrugations. Therefore, it is understood that mesh corrugation shapes can be modified as well as the trough's angles without departing from the spirit and scope of this disclosure. For example, the trough can have repeating angles, such as a zigzag, or turns, or smooth gradual turns and so forth, wherein the corrugations may conform to the frough angles.
In addition to assisting in stiffening the mesh, the corrugations may result in an non-smooth or uneven mesh surface, which naturally allows collected debris to dry quicker (due to separation between the debris and the mesh surface) and blow off more easily when there is ambient wind.
In various embodiments, it has been discovered that the cross sectional “crease” forming trough 245 also can operate to increase the structural integrity of the surface area of the mesh 235 over the gutter 220. It is understood for a large spanning mesh 235, the placement of trough 245 in the middle of mesh 235 may lessen its ability to independently support mesh 235. For example, if the mesh 235 is composed of a steel mesh having a wire diameter that is less than 0.01″ thick, with a weave count of more than 32 wires per linear inch (See
If the wire diameter decreases, then the wire count per inch increases—this will make the mesh 235 less stiff and unable to sustain itself over a gutter 220 when a cross sectional crease (e.g., trough 245 or similar trough) is formed. For wire diameters that are between 0.009″ and 0.01″ (thicker wire applied to the lessor wire count per inch), with wire counts of 32 to 60 per inch, the trough 245 can be displaced from the front strip connector 215 by up to 1.5.″
For wire diameters that are between 0.007″ and 0.089,″ with wire counts of 36 to 56 per inch, the trough 245 can be placed up to 0.75″′ from the front strip connector 225. For wire diameters that are between 0.005″ and 0.069, “with wire counts of 40 to 50 per inch, the trough 245 can be placed up to 0.25″ from the front strip cormector 225.
However, the trough 245 could be formed on the mesh 235 between the rear and front strip connectors (215 and 225) on a standard 5 inch gutter top opening, if the wire diameter is between 0.011″ and 0.015″ and the wire count is between 20 and 31 per inch. If a lower wire count per inch of between 10 and 19 is needed, then the wire diameter would need to be between 0.016″ and 0.02.″ However, with the wider mesh hole openings, as in the latter example, pine needles and small leafy debris may penetrate into the mesh 235 and into the gutter 220, potentially clogging the gutter 220 to cause rainwater to spill out of the gutter 220. Accordingly, while a lower wire count per inch for mesh 235, such as 20 wires per inch or less, can be used, it will be less effective in debris preclusion.
Having the mesh-clinging rainwater drop in to the middle of the gutter 220 rather than near the front lip 230 of the gutter 220 reduces the possibility that rainwater will run out of the gutter 220. However, because a higher wire count per inch functions to keep out leaves, pine needles and roof sand grit, etc. from entering the gutter 220, the mesh 235 will be stiffer and accordingly trough 245 can be close to or adjacent to the front strip connector 225.
The trough 245 can be, for example, V-shaped to provide stability, strength and rigidity for supporting the back bend 246 of the trough 245, as shown in
The corrugations 212 on the mesh 235 of this embodiment 200, include at least one corrugation 213 that extends from an upper edge of the mesh 235 (near connector 215) into a portion of the trough 245. The corrugation 213 does not extend all the way through the through 245 to the lower edge of the mesh 235 (near connector 225). The corrugations 212 further include at least one corrugation 214 that extends from the lower edge of the mesh 235 through the trough 245. The corrugation 214 in this embodiment does not extend all the across the surface of the mesh 235 to the upper edge. In other exemplary embodiments, the corrugations do not extend into the trough.
As shown in the cross-sectional illustration of
Understanding that additional and/or varied shaped troughs can also be formed,
It should be apparent that the V-shaped troughs in
Both trough designs shown in
The reason the snowmelt exits over the side of a mesh gutter cover is because the mesh is not wet since there is no rain. Moreover, it is possible the mesh is frozen, preventing penetration of the snowmelt into the mesh. In either instance, the snowmelt coming down the roof tends to not penetrate the permeable mesh material and consequently runs along the top of the mesh and then over the front of the gutter. It should be understood that snowmelt can occur in below freezing weather, wherein the roof under the snow is warmed by the home's heat, causing the snowmelt.
In contrast, when it is raining (which means the temperature is above freezing), snowmelt will come off the roof and with the mesh wet from the rain, the snowmelt will drop through the mesh and into the gutter. The warming rain droplets striking any snowmelt on the mesh will also help force the snowmelt through the mesh.
Because of the snowmelt issue, the downward trough designs illustrated in

Also, in various embodiments, the trough(s) shown may be composed of the mesh material with or without corrugations. That is, one or more of the trough surfaces H and/or G (seen in
