The present invention pertains to rain gutters for homes and buildings with sloped roofs.
The rain gutter system is an essential component for any home or building. The rain gutter system collects rain runoff from the entire surface area of the building's roof and transfers the runoff to a drainage system. Without a properly functioning rain gutter system, that same runoff is forced to the edge of the roof where it then falls onto the grounds adjacent to the building. This can obstruct visibility through windows underneath the roof edge and also produce excessive noise as the rain runoff aggregates into larger droplets or flows of water that drop from the roof to the ground adjacent to the building. Worse yet, rain runoff that is not properly redirected to drainage systems can result in flooding as the aggregate rain from the surface area of the roof is pooled to a much smaller area in the grounds adjacent to the building. This can cause damage to the foundation of the building and ruin landscaping. Beyond these functional roles, rain gutter systems also serve an aesthetic purpose to some by providing a bordering to the roof.
Rain gutter systems for homes and other buildings with sloped roofs have not changed for several decades. The standard rain gutter system involves U-shaped channels that overhang from the edge of the roof and that collect the rain runoff. The channels are interconnected at a slope so as to force the collected rain runoff to one end of the channel where the rain runoff is funneled into an enclosed channel that spans the vertical height of the home or building. The enclosed channel then redirects the rain runoff into a drainage system or other plumbing that moves the water away from the home.
While effective in their roles, these systems are in need of radical redesign to lower the cost of goods, reduce installation time and cost, and provide an alternative in building aesthetics. With regards to the cost of goods, standard overhanging rain gutter systems are produced with an unnecessary amount of raw materials. Specifically, the U-shaped channels that funnel the rain runoff from the roof are three-sided segments. Each three-sided segment includes material for a right lateral side, a left lateral side, and a bottom side with the material comprising either metal, aluminum, or hardened plastic. Therefore, one way to lower the cost of goods associated with standard rain gutter systems is to provide a redesigned system that does not need as many raw materials or, more specifically, provide a redesigned system that performs the same functional roles with a two-sided or single-sided channel In so doing, the cost of the raw materials needed for a gutter system is effectively reduced by a half or two-thirds.
With regards to installation time and cost, installation of a standard overhanging rain gutter is normally beyond the capabilities of the typical do-it-yourselfer and requires a contractor or one or more handymen to perform the installation. This is because of the danger that is involved in installing any structure to the edge of a roof irrespective of the fact that the channels are heavy and require one person to hold the channel in place while another secures the channel to the roof. Installation is also time-consuming because several brackets must be drilled, nailed, or otherwise secured to the roof in order to support the weight of the channels spanning the entire width of the roof. Moreover, overhanging rain gutters can damage the roof itself as water can enter through the mounting points of the brackets and thereby seep into and damage the underlying wood framework for the roof. Also, the brackets must be precisely installed so as to support the channels at an appropriate angle, thereby producing the slope by which gravity pulls the collected rain runoff to one end of the channel. An unforeseen cost is also the time or money needed to clear these systems from leaf and other debris buildup that could otherwise clog or render such systems ineffective. Every so often, someone has to remove such blockages from the channels. This can be done by the building owner with a ladder, but the time required to do so is nevertheless a cost.
As architecture has evolved, the standard rain gutter system has not. With regards to aesthetics, the look of the overhanging gutter system has become so commonplace that it is either ignored or viewed as an eyesore by some. Consequently, the standard rain gutter system simply does not conform aesthetically with the architecture or other design elements of some homes or buildings.
Accordingly, there is a need for an entirely new and improved rain gutter system. Such a system should be cheaper to manufacture, easier to install, and provide a different aesthetic on the home or building that is installed with such a system. Moreover, these advantages should be achieved without other tradeoffs with respect to effectiveness in removing rain runoff from the roof and without the introduction of other costs in maintenance, repair, or damage caused to the home or building that is installed with the rain gutter system.
It is an objective of the present invention to provide an alternative to standard overhanging rain gutter systems found on nearly every home and building with a sloped roof. It is further an objective to provide an alternative rain gutter system that is cheaper to manufacture, easier and less time consuming to install, and one that provides a different aesthetic to the standard overhanging rain gutter system. Moreover, it is an objective to provide these and other benefits without detrimentally affecting the functionality of the rain gutter system in effectively redirecting and removing rain runoff from a roof.
To achieve these and other objectives, a new rain gutter system is provided that takes advantage of the existing configuration of a sloped roof in order to minimize the raw materials that are needed to create a channel to redirect rain runoff, simplify the installation, and provide a new aesthetic to the building that is different than that provided by any overhanging rain gutter system. The system includes a set of interlocked segments that are placed about perpendicular to the roof atop the roof. The segments create a horizontal channel that is slightly angled from one edge of the roof to the other. The segments also create a non-permeable barrier at the intersection of the segments with the slope of the roof which causes the rain runoff running down the slope of the roof to be redirected into the channel and passed to one edge of the roof where it is deposited into a drain. The end segment may include a receptacle and a spigot that collects the runoff and redirects the runoff into a vertical drain.
The non-permeable barrier is established by laying a water-proof skirt that extends from the bottom of each segment upwards against the slope of the roof. The skirt can be inserted underneath the shingles or sealed with a sealant to establish the non-permeable barrier. Alternatively, some embodiments create the end of the skirt thin enough such that it may be allowed to rest bare atop the roof and still provide a sufficient non-permeable barrier.
Installation for such a system is simplified because only the end segments at either edge of the roof need to be secured to the roof. The intermediary segments are held in place by interlocking with one another and with the end segments using a male-female coupling mechanism. As such, the roof is only modified when securing the two end segments to the roof using nail, screws, clamps, or other securing mechanisms. Cost is also reduced when compared to traditional overhanging gutter systems. The system described herein requires fewer raw materials as it foregoes the need for a three sided “U” shaped channel to redirect the rain runoff. Instead, the system leverages a two sided “V” shaped channel, wherein one of the sides is the roof itself.
In order to achieve a better understanding of the nature of the present invention, various embodiments of the new rain gutter system will now be described, by way of example only, with reference to the accompanying drawings in which:
In the following detailed description, numerous details, examples, and embodiments of the new rain gutter system are set forth and described. As one skilled in the art would understand in light of the present description, the system is not limited to the embodiments set forth, and the system may be practiced without some of the specific details and examples discussed. Also, reference is made to accompanying figures, which illustrate specific embodiments in which the invention can be practiced. It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the embodiments herein described.
The rain gutter system advocated herein does away with the traditional overhanging rain gutter and replaces this effective but costly and time consuming standard with a simple, minimalistic, and unobtrusive design. This new design takes advantage of the existing configuration of a sloped roof in order to minimize the raw materials that are needed to create a channel to redirect rain runoff, simplify the installation, and provide a new aesthetic to the building that is different than that provided by any overhanging rain gutter system. In summary, the design integrates the roof as part of the rain gutter system.
This design provides several benefits over the traditional overhanging rain gutter systems of the prior art. Firstly, cost of materials is reduced. The parts of the new system include single-sided or inverted “V” shaped segments in contrast to the three-sided U-shaped channels of an overhanging rain gutter system. Accordingly, the parts for the new rain gutter system are easier to manufacture and constitute fewer raw materials, making them far cheaper to mass produce. Secondly, installation of the new rain gutter system is greatly simplified relative to traditional overhanging rain gutter system. This new system requires only two points of installation at a minimum. The first installation point is at one edge of the roof where a first end segment is anchored to the roof and the second installation point is at the opposite edge of the roof where a last end segment is anchored to the roof. All segments in between are supported by interlocking directly or indirectly with these two anchor segments. In other words, an installer need only drill holes, nail, or otherwise secure the anchoring end segments to the roof. The rest of system is interconnected without further modification to the roof. Thirdly, the new rain gutter system provides an entirely different aesthetic to the building. The height of the segments can be as low as one inch so that the entire system is almost imperceptible from a distance. In this manner, the new gutter system does not interfere with the architecture of the building or other design elements of the building as would a traditional overhanging rain gutter system. Fourthly, the new gutter system is less susceptible to clogging and the cleaning of the new gutter system is far simpler than traditional overhanging gutter systems. In fact, the new gutter system effectively cleans itself by using the rain the runoff to channel fallen leaves and other debris away from the channel and over a side of the roof.
The new rain gutter system is comprised of a start anchor segment, a plurality of intermediary segments, and an end anchor segment. The segments (i.e., start, intermediary, and end) interlock with one another in order to form a channel of sufficient width to accommodate roofs of different sizes.
The start anchor segment and the end anchor segment are the end pieces of the gutter system. As such, these segments are located at either the right edge or the left edge of the roof. These segments establish the position and angle of the entire gutter system and may be the only two segments that are physically secured to the roof, thus making installation of the entire rain gutter system easy and efficient. Additional anchor blocks may be used for added support when the roof is excessively wide or as will be discussed below, some of the intermediary segments may include an anchor block for additional support. The start anchor segment is vertically offset and positioned higher on the roof than the end anchor segment. The intermediary segments interlock in between the start and end anchor segments to create the angle for the gravity assisted channel that leads rain runoff to drainage. An installer will typically secure the position of the end anchor segment first before securing the start anchor segment and before interlocking the intermediary segments. The installer will want the end anchor segment to align with the vertical drain so that the collected rain runoff is directed from the gutter system into the vertical drain.
As shown in
The start anchor segment should be elevated with at least a three degree angle from the position of the end anchor segment. The steepness of the angle determines the rate at which rain runoff is channeled off the roof. Accordingly, a larger angle may be used for locations that receive greater amounts of sustained rainfall and where faster drainage is desired. However, there is no hard and fast rule for this angle or the offset between the start and end anchor segments. This further simplifies the installation as the installer can proceed with the installation quickly without the need for measuring.
The anchor blocks 210 and 215 provide the means by which to secure either a start anchor segment or end anchor segment to the roof. As shown, the first anchor block 210 is located behind the segment at a proximal end and the second anchor block 215 is located behind the segment at a distal end. The anchor blocks 210 and 215 are solid structures containing a receptacle (see reference markers 240 and 250). Each anchor block 210 and 215 can be made from hardened rubber or plastic. Each receptacle 240 and 250 may include an unthreaded hole through which a nail passes or a threaded hole through which a screw passes. The two nails or screws are longer in length than the length of the anchor blocks 210 and 215 so as to pass through the entire length of the segment and penetrate into the roof. The two nails or screws establish and maintain the position and angle at which the start or end anchor segment is secured to the roof.
Installation is therefore as simple as positioning the anchor segment at an end of the roof at a desired angle and hammering in two nails or driving in two screws into the roof to affix the position of the anchor segment to the roof. This results in much quicker installation time, much easier installation, and far less physical modification to the roof than required for the installation of traditional overhanging gutter systems.
Some embodiments provide start and end anchor segments with different anchor blocks than those described above. For example,
In still some other embodiments, the anchor block can be an adjustable bracket that can be resized to clamp to an outer beam below the surface of the roof. Nails or screws can be used to secure the clamp to the beam. In some such embodiments, the bracket includes an inner shaft that slides in to and out from an outer shaft to adjust a height of the bracket. The inner shaft contains a series of holes that align with a hole on the outer shaft when the inner shaft is slid in and out of the outer shaft. A pin or screw mechanism inserted through a hole along the inner shaft that is aligned with the hole of the outer shaft sets the height of the bracket. A similar inner shaft and outer shaft combination can be used to set the width of the bracket. These adjustments allow the anchor block to clamp to beams of varying sizes that run underneath the roof surface. Receptacles along the bracket receive nails or screws in order to secure the position and angle of the start or end anchor segment to the roof.
With reference back to
In some embodiments, the body 220 rises one inch vertically. At one inch in height, the segments of the gutter system are nearly imperceptible from a distance. However, other embodiments provide for a body 220 that rises anywhere from half an inch to six inches in height. The height of the body 220 determines the amount of rain runoff that can be carried by the channel at any given moment. Therefore, a body 220 having a height greater than one inch would be better suited for locations that receive heavy sustained rainfall, wherein at such locations, the aggregate rain runoff collected at any position along the channel may reach over one inch in height. In other words, the height of the body 220 acts as a dam that holds the rain runoff from reaching the roof ledge, with the angle of the segments creating the necessary force to redirect the rain runoff to the roof edge where a drainage system removes the water from the roof. In some embodiments, the body 220 of each segment is one to five feet in width. Though, shorter and greater widths can be manufactured to allow the gutter system to fit the width of any roof segment by up to one foot.
In order to interlock the segments, the body 220 of a start or end anchor segment includes interlocking element 235 at one end, while the intermediary segments include an interlocking element 235 at either end of the segment. In the case of a start anchor segment, the interlocking element 235 can be a male coupler with the end anchor segment having the complimentary female coupler or vice versa. In the case of the intermediary segment, the segment includes a male coupler at one end and a female coupler at the other end. Any number of male-female coupling mechanisms can be used to interlock the segments. Some examples will now be given. However, these examples are not intended to be exhaustive or limiting and it should be apparent to one of ordinary skill in the art that other interlocking mechanisms can be used.

With reference back to
The outer membrane 230 is wedge shaped and is a singular piece at the apex. Some distance below the apex, the outer membrane 230 splits to provide a central cavity within which the rigid frame of the body 220 is housed. The outer membrane 230 extends below the body for some distance and forms two skirts.
When a segment is placed perpendicular to a roof, each skirt flexes outward from the center of the segment. A first skirt flexes outward toward the apex of the roof and a second skirt flexes outward towards the ledge of the roof.
The first skirt sits flush against the roof and causes rain runoff to flow from the roof shingles over to the skirt and collect in the channel of the corresponding segment. The first skirt thereby creates a barrier that prevents rain runoff from running underneath and past the segments. In some embodiments and as shown in
The second skirt also sits flush against the roof. The primary purpose of the second skirt is to buttress the position of the segment and provide friction to prevent movement of the segment along the roof. Secondarily, the second skirt acts as a second seal to prevent any rain runoff that passes under the first skirt from passing past the segment. Instead, an unseen second channel is formed in between the inverted “V” frame of the body.
In some embodiments, the second skirt is omitted such that only the side of the segment that points towards the roof apex is housed with the non-permeable membrane. In some such embodiments, the entire body of the segment is not shrouded by the non-permeable membrane.
In some embodiments, the width of each of the first and second skirts is greater than the width of the body so as to provide overlap when one segment interlocks with another. This provides a continuous channel over which rain runoff will flow until it reaches the drain at the end anchor segment. Specifically, when the interconnection of the segments is achieved by placing one segment over an extruding male coupler of another segment, the skirts for the top segment will overlap and partially cover the skirts of the underlying segment. When the top segment is up-channel and the underlying segment is down-channel, that rain runoff will flow from the top segment to the underlying segment and the overlap of the skirts will retain the rain runoff wholly within the channel without the need of any additional sealant or waterproofing.
As noted above, one enhancement that can be made to the design includes providing different length intermediary segments to allow installers to easily adjust the length of the gutter to the roof width. Another enhancement includes providing one set of intermediary segments that have an anchor block behind and in the middle of the segment and another set of intermediary segments that do not have an anchor block. The intermediary segments with the anchor block can be secured to the roof in the same manner as the anchor segments. These enhanced intermediary segments are intended to be interspersed between other intermediary segments that do not include the anchor block as a means of providing additional rigidity to the gutter if desired. The intermediary segments with the anchor blocks may be desired in areas that experience heavy rainfall, wherein the additional rigidity afforded by these segments can offset the force and weight of the aggregate rainfall against the segments.
In some embodiments of the rain gutter system, the non-permeable membrane is disassociated or detached from connecting segments that include intermediary connecting segments and anchor connecting segments. In some such embodiments, the non-permeable membrane is divided into sections, each section spanning some length and having opposite lateral ends. Each end of a non-permeable membrane section couples to a different connecting segment. Each connecting segment couples together two sections of the non-permeable membrane. In some embodiments, adjacent membrane sections that are attached by one connecting segment are provided some degree of overlap so as to create a continuous channel with the two adjacent sections. In addition to coupling together two sections of the non-permeable membrane, each connecting segment also acts to retain a position of the non-permeable membrane sections over the roof. The position of at least two anchor segments is secured to the roof by nailing or screwing those segments to the roof. Other intermediary segments are held in place by interconnecting with the anchor segments using the non-permeable membrane sections.
Each non-permeable membrane section 1410 has an upward rising section and a skirt extending below the upward rising section. The skirt thickness narrows at the outermost tip. This allows the skirt to slide underneath roof shingles or to abut the roof shingles such that water flowing over the roof shingles continues over the skirt until contacting the upward rising section where it is then redirected horizontally across the width of non-permeable membrane section 1410. In some embodiments, the skirt bends from the upward rising section so to provide flexion in order to accommodate roofs with different pitches. In some embodiments, the width of the skirt, or more generally, the membrane section 1410 is elongated at one end so as to overlap with an adjacent membrane section when the two sections are coupled by a connecting segment 1420. In
A special drain section is provided as an end piece for the gutter system. The drain section also couples to any of the connecting segments 1420.
Formed over the front leg of the framework is the connecting segment face 1730. The connecting segment face 1730 is shaped complimentary to the shape of the non-permeable membrane sections 1410. Accordingly, the connecting segments face 1730 is typically concave in shape. About the face 1730 is a coupling groove 1740.
The coupling groove 1740 along with the lateral ends of the non-permeable membrane sections 1410 are parts of a male-female coupling mechanism used to couple two membrane sections 1410 to the connecting segment. In some embodiments, the coupling groove 1740 comprises at least top lip, though some embodiments further provide a bottom lip. The top and bottom lips extend over the connecting segment face 1730 and extend towards the center by some distance, thus providing the female coupler of the male-female coupling mechanism. The lateral ends of the non-permeable membrane sections 1410 are the male couplers of the male-female coupling mechanism. Specifically, the lateral ends slide into the opening between the lips and the connecting segment face 1730 where they are then held in place. To create the continuous channel over which the collected rain runoff flows, the coupling groove 1740 may be sized to allow one end of a first non-permeable membrane section to slide underneath the inserted end of a second non-permeable membrane section. The overlap causes the collected rain runoff to flow from the second non-permeable membrane section to the first non-permeable membrane section without any break in the channel Some embodiments allow for less of an overlap by allowing the coupled membrane sections 1410 to abut within the coupling groove 1740 with some amount of the skirt of one membrane section overlapping with that of the other.
The coupling groove 1740 can provide force or other coupling means to lock the position of the inserted membrane sections 1410. The force can stem from spring-like properties that are manufactured into the coupling groove 1740. The spring-like properties cause the outer lip of the groove 1740 to press against the face 1730 of the connecting segment 1420. With some counter-force, the outer lip can be displaced from the connecting segment face 1730 to allow for insertion of the membrane section 1410 ends. Once the ends have been positioned, the counter-force can be removed, causing the outer lip to press the inserted ends of the membrane sections 1410 against the connecting segment face 1730, thereby holding them in place. Thus, the coupling groove 1740 provides a clamping force to hold the membrane sections 1410 in place.
In some other embodiments, the coupling groove 1740 does not exert any force on the ends of inserted non-permeable membrane sections 1410. Rather, the inserted sections 1410 are held in place based on their resting position within the coupling groove 1740.
An alternative nub and hole male-female coupling mechanism is illustrated in
Some embodiments of the connecting segments 1420 forego the coupling groove 1740 altogether, instead providing the male-female coupling assembly as the sole means for coupling the non-permeable membrane sections 1410 to the connecting segment 1420. Any male-female coupling including the aforementioned nub and hole mechanism can be used.
In still some other embodiments, holes are provided on the connecting segment face 1730 and upward rising section of the non-permeable membrane sections 1410. To couple the pieces, a hole of one membrane section 1410 is aligned over a hole along the connecting segment face 1730, a bolt is slid through both holes, and a nut is tightened at the end of the bolt.
In some embodiments, the top lip and the bottom lip of coupling groove 1740 are one piece extending over the full length and curvature of the connecting segment face 1730.
As shown in
Some embodiments include capsules within each of receptacles. The capsules hold a sealant. When a nail or screw is driven through the capsule, the capsule ruptures and the sealant flows into and around the hole that is made into the roof surface by the nail or screw. When the sealant cures, the hole is waterproofed, preventing any water from entering into those holes.
