(13) Now referring to FIG. 1, which shows an exemplary embodiment of a gutter section 100 according to the present invention. As depicted in FIG. 1, the gutter section 100 comprises a rear wall 105, a front wall 110 and a base 115 forming a body of the gutter section 100. The top of the gutter section 100 is open. A keyway 120 is disposed on the front wall 110 and runs along the length of the body of the gutter section 100. Second keyway 125 is disposed on the rear wall 105 and runs along the length of the gutter section 100. A third keyway 130 is disposed at an intersection of the rear wall 105 and the base 115, and the keyway 130 runs along the length of the gutter section 100. Further can be seen a screw boss 135 disposed on the front wall 110 and the screw boss 135 running along the length of the gutter section 100. A groove 140 is disposed on the upper portion of the front wall 110 and runs along the length of the gutter section 100. The groove 140 and the keyway 125 are configured to hold a gutter guard 145 as shown in FIG. 1. Another groove 150 is provided on the top portion of the rear wall 105 and the groove 150 runs along the length of the gutter section 100. The groove 150 is configured to secure a metal flashing (not shown). An angled shelf 155 configured on rear wall 105 directs the screws for mounting the gutter section 100 to a supporting surface.

(14) The base 115 of the gutter section 100 is curved to provide an aesthetic appearance to the gutter section. It is to be noted that the gutter section can be made in any other shape without departing from the scope of the present invention. For example, FIG. 2 shows a square-shaped gutter body. The body of the gutter sections can be made of commercially available metals. Heavy-gauge aluminum has been found suitable for gutter sections, in accordance with an embodiment of the present invention, but it is within the contemplation of this invention that other materials, such as galvanized steel, copper or cuprous alloys, or even plastic might also be utilized. Preferably the gutter section in the form of a flat continuum made from metal which is strong, durable, weather-resistant, easily formed, and substantially rigid, yet susceptible to some bending without breakage. According to a preferred embodiment, an elongated gutter can be made by extrusion process and the gutter sections of the desired length can be cut from the elongated gutter. The gutters of the present invention made by the extrusion process are durable, thicker and stiffer than the gutters made by the roll forming process. Such extruded gutters can easily withstand external shocks, such as damage from a foreign object. For example, in case a ladder is supported on the installed gutter, the durable gutter of the present invention could withstand any dents that may be caused by the weight of the ladder. In one case, the thickness of the body of the gutter section can range from 0.10 inches to 0.20 inches.

(15) The gutter section 100 shown in FIG. 1 is mounted over a supporting surface at the rear wall 105. The supporting surface in one exemplary embodiment is fascia. The term fascia herein connotes a vertical frieze or band under a roof edge. Rainwater gutters are typically installed over the fascia. The rear wall of the gutter sections is shaped according to the surface of the fascia. Shown in FIG. 1 is the flat upper portion of the rear wall 105, which can be supported over a flat supporting surface. The front wall 110 and the base 115 could be shaped to provide aesthetic appearance in the gutter section 100. For example, the front wall and the base could be shaped like ornamental wood moldings used in the buildings. It is to be understood that the terms rear wall, front wall, and the base does not limit the invention in any way. These are used to explain the structure of the gutter and does not denote any structural limitations. Moreover, the gutter could be produced in any shape as desirable, for example, a single wall U-shaped gutter or a rectangular-shaped gutter.

(16) The keyways are used to connect two gutter sections. Elongated keys shaped to be received in the keyways are partially inserted in the keyway of the first gutter section. The second gutter section having the similar keyway is mounted over the protruding portion of the keyway, thus joining the two gutter sections. FIG. 3 shows two gutter sections connected through elongated keys. As shown in FIG. 3, the gutter section 100 of FIG. 1 is connected to second gutter section 300 through three elongated keys 160. The keyways 120, 125 and 130 shown in FIG. 1 are square-shaped, so the square-shaped keys 160 are can be used. The square-shaped elongated keys 160 is half inserted in the gutter section 100, wherein the gutter section is already mounted on the fascia. Second gutter section 300 is moved in the remaining half portion of the elongated keys 160 and then coupled to the fascia. Alternatively, the gutter can be assembled separately and then mounted on the supporting surface. Basically, the gutter sections can be joined to get the gutter of desired length and the gutter can then be mounted over the supporting surface. The gutter sections are joined similarly as described above i.e. through the keyways. It is to be understood that the figures show the keyways and the elongated keys to be square-shaped, however, the keyways and the elongated keys could be of any other shape without departing from the scope of the present invention. For example, keyway can be of a shape such as rounded, prismatic, rectangular and like. Moreover, FIG. 3 show the gutter sections connected through three keyways. It is to be understood that only one keyway can connect the two gutter sections and the other keyways are optional. Thus, the present invention can contemplate one or more keyways.

(17) The elongated key could be bonded to the keyways using an adhesive. Alternatively, any other method obvious to a skilled person for bonding the key to the keyway is within the scope of the present invention. In one case, the keyways are positioned such as they do not obstruct in cleaning the inside of the gutter sections. For example, in FIG. 1 the keyways 120 and 125 are disposed on upper portions of the front wall 115 and the rear wall 125. The third keyway 130 is disposed in the outer portion of the intersection, thus the inner portion of the gutter section is plain that could be easily cleaned.

(18) The gutter guard is used to keep out debris, such as leaves and twigs, without restricting the flow of water into the gutter. Structure and functions of the gutter guards are known in the prior art and any variety of different types of gutter guards can be embodied in the present invention. For example, imperforate styles, expanded metal panels, etc. can be used without any limitations. The keyway 125 in FIG. 1 is shown holding the gutter guard 145 at one side. The gutter guard 145 has ribs on the opposite side running along the length of the gutter guard 145. The ribs are configured to be slidably received into the grove 140 and the keyway 125 for mounting the gutter guard 145 over the gutter section 100. Alternatively, the gutter guard 145 can be snapped into the groove 140 and the keyway 125. It is to be noted that the gutter guard 145 and the groove 140 are optional i.e. the gutter section 100 can be contemplated without the gutter guard 145.

(19) An optional screw boss 135 is shown in FIG. 1. The screw boss 135 runs parallel to the keyways and end-to-end along the length of the gutter section 100. The screw boss 135 includes a central aperture in which a fastener (not shown) is received. The fasteners like the keyways can be elongated pins used to connect two gutter sections, but at an angle other than 180 degrees. The elongated pins can be bent to the desired angle for connected the two sections in the desired angle. For example, two gutter section can be coupled perpendicularly by bending the elongated pins 90 degrees. Thus, the gutter section can be coupled at odd angles through the screw bosses, wherein the alignment pins are bent accordingly. It is to be noted that the screw bosses are optional the gutter section according to the present invention can be embodied without the screw bosses. FIG. 6 is shows two gutter sections 610 and 620 being coupled at an odd angle. The gutter sections 610 and 620 are shows at separated so that the elongated pins 630 and 640 are visible clearly. The elongated pins 630 and 640 are shown to be bended and received into the screw bosses 625 of each gutter sections 610 and 620. The gutter section further having the keyway 650 behind the front wall 660. FIG. 6 is for showing the gutter section coupled through elongated pin at an odd angle, however the end part of the gutter section be cut at an angle such that the two gutter sections can be joined.

(20) The gutter sections are mounted over a supporting surface, such as fascia using screws. In operation, the gutter section is placed over the supporting surface and mounting screw are drilled through the wall of the gutter section into the supporting surface. Considering the shape of the gutter, and, because the screws need to be about 4 long, they have to be installed at a downward angle in order to not hit the face of the gutter as they are being installed. The wall of the gutter body is modified with an angles shelf for indexing the mounting screws. FIG. 1 shows the angles shelf 155 disposed on the rear wall 105 of the gutter section 100. The angled shelf 155 assist in drilling for the mounting screws and to prevent the drill bit from moving on the slippery surface of the gutter body wall. Furthermore, the shape (angle) of angled shelf 155 ensures that the head of the mounting screws sits flat against the inside of the gutter body wall. The present invention is advantageous that, being durable and rigid, no internal supports or external hangers may be required for installation.

(21) Metal flashing can be used to provide a pathway for the water from the roof into the gutter. Metal flashing can be an elongated sheet extending from the roof and secured into a groove providing pathway for the water, such that water does not leak into the supporting surface. In FIG. 1 the groove 150 is provided to secure the metal flashing to the gutter section 100.

(22) FIG. 4 shows an embodiment of an end cap 400. The end cap 400 has 3 three screws 410. The endcap is used to close the open ends of the rainwater gutter. The endcap 400 is shaped according to the gutter section of FIG. 1. The endcap 400 through the three holes 410 is screwed into the three keyways 120, 125 and 130 of the gutter section 100.

(23) FIG. 5 shows an exemplary embodiment of gutter section 500. The gutter section 500 is like the gutter section 200 shown in FIG. 2 but having a hole 510 in the base 215 for receiving a downspout connector. Downspout channelizes the water from the gutter into a drain. Section 500 can be connected to the other section through the keyways as explained above.
