DETAILED DESCRIPTION
(30) The following description is presented to enable any person skilled in the art to make and use the disclosed device, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the disclosed device. Thus, the disclosed device is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
(31) FIGS. 1-4 are photographs of prior art conventional intersections of downspouts and PVC downspout adapters, all of which were photographed at a residential property. FIGS. 1-4 illustrate the significant damage caused by string trimmers to both downspouts and adapters, as well as the disparity in the extension of drainpipes as to the soil level. The photographs illustrate the disruption to the functionality of residential and commercial drainage systems as a result of string trimmer and edger damage. The photographs further illustrate the destructive impact to the aesthetic appearance of residential and commercial drainage systems as a result of string trimmer and edger damage.
(32) FIG. 1 illustrates a downspout 20 severely damaged by a string trimmer to the point of reducing its internal cross-sectional area and fluid carrying capacity above a downspout adapter 10. Such damage increases the probability that downspout 20 will clog with debris and cease to function as designed. FIG. 1 further illustrates damage to downspout adapter 10 caused by the use of string trimmers. The damage impairs the aesthetic value of the residence, and risks damage to the residence from a nonfunctioning gutter system.
(33) FIG. 2 is a second photograph of the prior art. In FIG. 2, drainpipe 4 has been damaged and displaced by a string trimmer to disengage downspout 20 from adapter 10. Adapter 10 is mounted slightly above the soil line so as to be visible. Corrective realignment of either downspout 20 or adapter 10 is difficult. Surface debris may enter drainpipe 4 and drain water will flow externally of drainpipe 4. The damage impairs the aesthetic value of the residence, and risks damage to the foundation and the drainage system. An angled lower portion of downspout 20 would be a visible indicator of misalignment.
(34) FIG. 3 is a third photograph of the prior art. The damage to downspout 20 is clearly visible. In this example, downspout 20 has been separated from adapter 10, allowing surface debris to enter drainpipe 4 and drain water to spread externally of drainpipe 4. The damage impairs the aesthetic value of the residence, and risks damage to the foundation and the drainage system.
(35) FIG. 4 is a fourth photograph of the prior art. FIG. 4 illustrates the variance in height of mounting PVC downspout adapter 10 in relation to a soil surface 2. Drainpipe 4, on top of which downspout adapter 10 is mounted, extends far above soil surface 2. Downspout adapter 10 comprises a cylindrical coupling portion 12 and a rectilinear coupling portion 14 for receiving downspout 20. While the height of this drainpipe is unusually significant, variations in height of one to three inches above the surface are common.
(36) FIG. 5 is an isometric front view of an embodiment of drainage junction shield 100, illustrating various elements of that embodiment. The embodiment illustrated has five sections. Drainage junction shield 100 has a base 110. Base 110 comprises a plurality of base sections including a base right 112, a base right chamfer 114, a base front 116, a base left chamfer 118, and a base left 120 (see FIG. 6).
(37) As best seen in FIG. 11, a base access 122 is formed between a back edge of base right 112 and a back edge of base left 120. Base 100 and base access 122 form a hexagonal base perimeter 126 which defines an adapter chamber 124. Adapter chamber 124 is receivable of downspout adapter 10, which is a sewer and drain connector provided for flow enabled connection between downspout 20 and drainpipe 4.
(38) Referring back to FIG. 5, drainage junction shield 100 has an extension 150. Extension 150 comprises a plurality of extension sections including an extension right 152, an extension right chamfer 154, an extension front 156, an extension left chamfer 158, and an extension left 160 (see FIG. 6).
(39) As seen in FIG. 5, an extension access 162 is formed between a back edge of extension right 152 and a back edge of extension left 160. The uppermost extent of extension 150 and extension access 162 forms a rectangular entry perimeter 168. The volume between extension right 152, extension right chamfer 154, extension front 156, extension left chamfer 158, and extension left 160 defines a downspout chamber 164. Downspout chamber 164 is receivable of downspout 20 for flow enabled connection between adapter 10 and drainpipe 4.
(40) As seen in FIGS. 24 and 25, a flange right 132 extends perpendicularly outward from base right 112. A flange right chamfer 134 extends perpendicularly outward from base right chamfer 114. A flange front 136 extends perpendicularly outward from base front 116. A flange left chamfer 138 extends perpendicularly outward from base left chamfer 118. A flange left 140 extends perpendicularly outward from base left 120.
(41) Flange right 132, flange right chamfer 134, flange front 136, flange left chamfer 138, and flange left 140, each have a plurality of anchor holes 142 for receiving soil pins 144 (see FIG. 14).
(42) FIG. 6 is a left side view of the embodiment of the drainage junction shield 100 of FIG. 5. As seen in FIG. 6, extension left 160 extends above and is contiguous with base left 120. Extension left chamfer 158 extends above and is contiguous with base left chamfer 118. Base left 120 is contiguous with base left chamfer 118. In the embodiment illustrated, decorative element 170 is located on base left 120. Extension left 160 is located in alignment with extension left chamfer 158.
(43) FIG. 7 is a right side view of the embodiment of the drainage junction shield 100 of FIG. 5. As seen in FIG. 7, extension right 152 extends above and is contiguous with base right 112. Extension right chamfer 154 extends above and is contiguous with base right chamfer 114. Base right 112 is contiguous with base right chamfer 114. In the embodiment illustrated, decorative element 170 is located on base right 112. Extension right 152 is located in alignment with extension right chamfer 154.
(44) FIG. 8 is a front view of the embodiment of the drainage junction shield 100 of FIG. 5. Base front 116 is contiguous with base left chamfer 118 and base right chamfer 114. Extension front 156 extends above and is contiguous with base front 116. In the embodiment illustrated, extension front 156 is located in adjacent alignment with extension left chamfer 158 and extension right chamfer 154.
(45) FIG. 9 is a rear view of the embodiment of the drainage junction shield 100 of FIG. 5. As seen in FIG. 9 and also FIG. 11, adapter chamber 124 is the volume within the confines of base 110. As also seen in FIG. 9, downspout chamber 164 is the volume within the confines of extension 150.
(46) FIG. 10 is a top view of the embodiment of the drainage junction shield 100 of FIG. 5. FIG. 10 illustrates entry perimeter 168 of downspout chamber 164. Entry perimeter 168 extends from extension right 152, to extension right chamfer 154, to extension front 156, to extension left chamfer 158, to extension left 160 and across extension access 162. Extension right 152, extension right chamfer 154, extension front 156, extension left chamfer 158, and extension left 160 are inclined inward to form a converging surface structure above and over downspout chamber 164.
(47) FIG. 11 is a bottom view of the embodiment of the drainage junction shield of FIG. 5. FIG. 11 illustrates base perimeter 126 of adapter chamber 124. Base perimeter 126 extends from base right 112 to base right chamfer 114, to base front 116, to base left chamfer 118, to base left 120, and across base access 122.
(48) FIG. 12 is an isometric view of the embodiment of drainage junction shield 100, illustrated installed on a soil surface 2 adjacent to a wall 6 and protecting the intersection of downspout 20, adapter 10, and drainpipe 4. As seen in this view, downspout 20 passes through entry perimeter 168. Downspout 20, adapter junction 10, and drainpipe 4 are no longer visible and are protected from landscape machinery such as string trimmers and edgers. Wall 6 provides a plane of closure across base access 122 and extension access 162. Soil pins 144 extend through anchor holes 142 of a flange system 130 (see FIG. 10). As seen below soil surface 2, soil pins 144 are positioned to avoid contact with drainpipe 4.
(49) FIG. 13 is a rear isometric view of the embodiment illustrated in FIG. 12 with wall 6 removed for visibility. As seen from this view, downspout 20, adapter junction 10, and drainpipe 4 are no longer visible and are protected from landscape machinery such as string trimmers and edgers. In conventional stormwater assemblies, downspout 20 may be attached to wall 6 and transitions adapter 10, and drainpipe 4 will be located approximate to wall 6. Extension access 162 and base access 122 permit sliding engagement of drainage junction shield 100 into position before inserting soil pins 144 in anchor holes 142.
(50) FIG. 14 is a front subsurface view of the embodiment of the drainage junction shield installation 100 illustrated in FIGS. 12 and 13. In FIG. 14, drainpipe 4 is oriented 180 degrees away from the wall. Soil pins 144 are inserted in anchor holes 142 located in flange right 132 and flange left 140 as to avoid conflict with drainpipe 4.
(51) FIG. 15 is a side subsurface view of the embodiment of the drainage junction shield installation 100 illustrated in FIG. 12, illustrating again the absence of conflict between soil pins 144 and drainpipe 4.
(52) FIG. 16 is a top view of the embodiment of the drainage junction shield installation 100 illustrated in FIG. 12. As seen in this view, adapter 10 and downspout 20 are shielded within adapter chamber 124 and downspout chamber 164 of drainage junction shield 100.
(53) FIG. 17 is an isometric view of the embodiment of the drainage junction shield 100 of FIG. 5, illustrated installed on soil surface 2 adjacent to wall 6 and protecting the intersection of downspout 20, adapter 10, and drainpipe 4. In this view, drainpipe 4 is angled at approximately 45 degrees away from wall 6. In this view, soil pins 144 are relocated to anchor holes 142 in alternative flanges such as flange left chamfer 138 and flange front 136 to secure drainage junction shield 100 to soil surface 2.
(54) FIG. 18 is an isometric view of the embodiment of the drainage junction shield 100 of FIG. 5, illustrated installed on soil surface 2 adjacent to wall 6 and protecting the intersection of downspout 20, adapter 10, and drainpipe 4. In this view, drainpipe 4 is angled approximately parallel to wall 6. As with FIG. 17, in this configuration, soil pins 144 may be relocated to anchor holes in alternative flanges to secure drainage junction shield 100 to soil surface 2.
(55) FIG. 19 is an isometric view of an alternative embodiment of the drainage junction shield 100, designed for compatibility with downspout 20 that does not connect to drainpipe 4, but is for redirection of storm water away from wall 6 onto soil surface 2. This permits compatibility of the aesthetic appearance of downspout 20 to drainpipe 4 connections in buildings where some downspouts 20 are connected to drainpipes 4 and others are not. In this embodiment, drainage junction shield 100 includes a drain portal 210 for accommodating a downspout drain 22.
(56) FIG. 20 is an isometric view of the embodiment of FIG. 19 illustrated installed on soil surface 2 adjacent to wall 6 and protecting downspout 20. This embodiment illustrates the advantage of the cooperative configuration between base access 122, extension access 162 and downspout portal 210 in that drainage junction shield 100 may be slid into place against wall 6 without disruption of the assembly of downspout 20 and downspout drain 22.
(57) FIG. 21 is a rear isometric view of the embodiment illustrated in FIG. 20 with wall 6 removed for visibility. As seen in this view, the embodiment continues to benefit from the arrangement of soil pins 144 through flange system 130 through anchor holes 142. This permits a similar appearance to this embodiment as to the embodiment in which downspout 20 is not connected to drainpipe 4. While access to anchor holes 142 under flange front 136 may be restricted by downspout drain 22, there are several alternative anchor holes 142 in flange system 130 accessible for securing drainage junction shield 100 to soil surface 2.
(58) FIG. 22 is an isometric view of an alternative embodiment for a drainage junction shield 200 having three sides. This embodiment lacks certain benefits of the embodiment of drainage junction shield 100 shown in FIG. 5, such as superior aesthetic value, ability to enclose the round geometry of a conventional drainpipe 4 in closer proximity, and ability to better deflect, without rupturing, rotating strings of a string trimmer. However, drainage junction shield 200 may be less expensive to manufacture, depending on the method used.
(59) In this embodiment, base right 112 is contiguous with base front 116 and extension right 152. Similarly, base left 120 is contiguous with base front 116 and extension left 160. Extension front 156 is located in adjacent alignment with extension right 152 and extension left 160.
(60) Extension right 152, extension front 156 and extension left 160 are inclined inwards to form rectangular entry perimeter 168 for receiving downspout 20. The convergence of base right 112, base front 116, and base left 120 with extension right 152, extension front 156 and extension left 160, defines rectangular base perimeter 126 that outlines adapter chamber 124, which is sufficiently large to receive adapter 10 and drainpipe 4. Base perimeter 126 is larger than entry perimeter 168.
(61) Flanges 130 extend perpendicularly outward from base right 112, base front 116, and base left 120. Anchor holes 142 are provided on flanges 130 for receiving soil pins 144.
(62) FIG. 23 is an isometric view of another alternative embodiment of the drainage junction shield 300 in a four-sided form. In each embodiment 100, 200, and 300, placement of drainage junction shield (100, 200, 300) against wall 6 creates a complete enclosure of adapter chamber 124 and downspout chamber 164. This occurs because wall 6 provides an additional side by covering base access 122 and extension access 162.
(63) In drainage junction shield 300, base right 112 is contiguous with base right chamfer 114, base left chamfer 118, and base left 120. Base right 112 is contiguous with extension right 152. Base right chamfer 114 is contiguous with extension right chamfer 154. Base left chamfer 118 is contiguous with extension left chamfer 158. Base left 120 is contiguous with the extension left 160.
(64) Extension right 152, extension right chamfer 154, extension left chamfer 158 and extension left 160 are inclined inwards to form rectangular entry perimeter 168 for receiving downspout 20. The convergence of base right 112, base right chamfer 114, base left chamfer 118, and base left 120 with extension right 152, extension right chamfer 154, extension left chamfer 158 and extension left 160, defines a pentagonal base perimeter 126 that outlines adapter chamber 124, which is sufficiently large to receive adapter 10 and drainpipe 4. Base perimeter 126 is larger than entry perimeter 168.
(65) Flanges 130 extend perpendicularly outward from base right 112, base right chamfer 114, base left chamfer 118, and base left 120. Anchor holes 142 are provided on flanges 130 for receiving soil pins 144.
(66) It is readily understandable that base right 112 and extension right 152 may be a unitary structure in this embodiment, along with base left 120 and extension left 160. Thus, with no bend between the base 110 and extension 150 elements. In that configuration, only base front 116 is inwardly inclined.
(67) FIG. 24 is a bottom view of the embodiment of drainage junction shield 100 illustrated in FIG. 5, illustrating the various radial distances between anchor holes 142 and the proximate center of drainpipe 4. These distances were measured in one application of the embodiment and are provided in Table 1 below:
(68) TABLE-US-00001 TABLE 1 Line Inches 180 (x2) 3.92 182 (x2) 3.25 184 (x2) 3.40 186 (x2) 3.38 188 (x2) 3.41 190 3.49
(69) The data set of 11 points from Table 1 produces an average of 3.47, a standard deviation of 0.23 and the variance 0.05. This data set represents a close pattern of distances between a center point of drainpipe 4 and locations for placement soil pins 144. This advantageously provides even force resistance to displacement of drainage junction shield 100 in response to impact from string trimmers and other items associated with work and play in a landscape environment.
(70) FIG. 25 is a bottom view of the embodiment of drainage junction shield 200 illustrated in FIG. 22, illustrating the various radial distances between anchor holes 142 and the proximate center of drainpipe 4. These distances were measured in one application of the embodiment and are provided in Table 2 below:
(71) TABLE-US-00002 TABLE 2 Line Inches 280 (x2) 3.78 282 (x2) 3.28 284 (x2) 3.78 286 (x2) 3.66 288 2.71
(72) The data set of 9 points from Table 2 produces an average of 3.78, a standard deviation of 0.37 and the variance 0.14. This data set represents a less close and less even pattern of distances between a center point of drainpipe 4 and locations for placement soil pins 144. This pattern thus provides less even force resistance to displacement of drainage junction shield 200 in response to impact from string trimmers and other items associated with work and play in a landscape environment.
(73) FIG. 26 illustrates an embodiment for a method for manufacturing the 5-sided drainage junction shield 100 as illustrated in FIG. 5. In this method, a sheet metal template is provided by stamping or metal cutting process, and then folded to produce the 3-dimensional drainage junction shield 100. The metal template is preferably between 12 and 16 gauge steel. The method disclosed is advantageous because it does not require welding or fastening. The method comprises the steps of: a) providing a flat sheet metal template for drainage junction shield 100 similar to the example illustrated in FIG. 26; b) bend forming at 192 flanges 130 outward about 90 degrees to the template plane; c) bend forming at 193 extension left chamfer 158 and extension right chamfer 114 inward between 6 and 10 degrees to the template plane; d) bend forming at 194 extension left 160 and extension right 152 inward between 2 and 6 degrees to the template plane; e) bend forming at 195 extension front 156 inward between 20 and 24 degrees to the template plane; f) bend forming at 196 base left chamfer 118 and the base right chamfer 114 inward between 37 and 41 degrees to the template plane; and, g) bend forming at 197 base left 120 and base right 112 inward between 85 and 90 degrees to the template plane.
(74) FIG. 27 illustrates a manufacturing pattern for folding 3-sided drainage junction shield 200 as illustrated in FIG. 22. In this method, a sheet metal template is provided by stamping or metal cutting process, and then folded to produce the 3-dimensional drainage junction shield 200. The metal template is preferably between 12 and 16 gauge steel. The method disclosed is advantageous because it does not require welding or fastening. The method comprises the steps of: a) providing a flat sheet metal template for drainage junction shield 200 similar to the example illustrated in FIG. 27; b) bend forming at 292 flanges 130 outward about 90 degrees to the template plane; c) (optionally) bend forming at 293 extension left 160 and extension right 152 inward between 0 and 20 degrees to the template plane; d) bend forming at 294 extension front 156 inward between 5 and 40 degrees to the template plane; and, e) bend forming at 295 base left 120 and base right 112 inward between 85 and 90 degrees to the template plane.
(75) FIG. 28 illustrates a manufacturing pattern for folding a 4-sided drainage junction shield 300 as illustrated in FIG. 23. In this method, a sheet metal template is provided by stamping or metal cutting process, and then folded to produce the 3-dimensional drainage junction shield 300. The metal template is preferably between 12 and 16 gauge steel. The method disclosed is advantageous because it does not require welding or fastening. The method comprises the steps of: a) providing a flat sheet metal template for drainage junction shield 300 similar to the example illustrated in FIG. 28; b) bend forming at 392 flanges 130 outward about 90 degrees to the template plane; c) bend forming at 393 extension left 160 and extension right 152 inward between 0 and 15 degrees to the template plane; d) bend forming at 394 extension left chamfer 158 and extension right chamfer 154 inward between 5 and 40 degrees to the template plane; e) bend forming at 395 base left chamfer 118 and base right chamfer 114 inward between 5 and 30 degrees to the template plane; and, f) bend forming at 396 base left 120 and base right 112 inward between 85 and 90 degrees to the template plane.
(76) Drainage junction shields 100, 200, and 300 are impervious to deformation from engagement with a string trimmer, and thus protect the integrity of the connections between downspout 20, downspout adapter 10, and drainpipe 4.
(77) While this invention has been described in connection with a limited number of embodiments, it is not intended to limit the scope of the disclosed device to the particular form set forth, but, on the contrary, is intended to cover such alternatives, modifications and equivalents as may be included within the spirit and scope of disclosed device as defined by the appended claims.
