DETAILED DESCRIPTION
• Referring now to FIGS.[0009]1-3, there is shown agutter11 on amounting structure12, typically a fascia board, positioning the gutter just below the edge of aroof13 at the eave. Ashield14 is supported in thegutter11 by afastening device15 that fits in the gutter under theshield14.
• The[0010]gutter11 shown has abottom wall16, a front wall17 and aback wall18 forming a U-shaped channel or trough. The front wall17 has a channel shapedcoupling portion17aat the top that opens toward the rear and terminates in a back turnedlip17b.Thegutter11 functions in the conventional way collecting runoff water from theroof13.
• The[0011]shield14 extends forwardly and downwardly away from the back wall17 with agap19 between the front of the shield and front wall17. Theshield14 is made from a flat, flexible sheet metal, shaped preferably by roll forming to have anintermediate section21, arear section23 and afront section24. Theintermediate section21 shown is essentially flat, but typically may have a slightly upwardly bowed curve. Thefront section24 is formed along a selected radius R1. Therear section23 is formed along a selected radius R2. A shieldfront coupling portion27 is made by extending the material down from thefront section24 and rearwardly and back along a radius to form a female socket with an opening facing toward the front. A shield rear coupling portion28 is made by extending the material down from therear section23 and rearwardly along a radius to form a female socket with an opening facing toward the rear. Theshield14 will flex so that upon applying inwardly directed compression forces to the shield front andrear coupling portions27 and28 the material will flex so couplingportions27 and28 move inwardly toward one another to fit inside and bear against associated outside complementary shaped coupling portions on thefastening device15 described hereinafter. This provides a clip in fastening arrangement for fastening the shield to the second and third coupling portions of the fastening device. Theshield14 prevents debris from entering the gutter and facilitates water drainage into the gutter.
• The[0012]gutter11 andshield14 are maintained in rigid or fixed predetermined positions relative to one another by thefastening device15. Thefastening device15 integrates the gutter and shield into a shielded gutter system. Thefastening device15 includes an intermediate body portion31 for extending between the back wall and front wall of the gutter, abase portion32 at the rear of the intermediate body portion31 for attaching to amounting structure12 behind theback wall18 of the gutter to support the front wall of the gutter against movement. The intermediate body portion31 includes abase wall31aand aside wall31bextending transversely up from one side of the base wall. Theside wall31bhas a top edge that is angled upward from thesecond coupling portion38 to thethird coupling portion39 at the rear, providing a ramping surface for the rear of the shield to ride across while installing the shield from the front side of the gutter. In addition, the intermediate body portion31 may be configured such as with a notch in the top edge to hold the shield in an intermediate resting position prior to installation. This allows bulk placement of shields which can be installed at a later time.
• The[0013]fastening device15 has afirst coupling portion33 at the front that rigidly inter-fits with afemale coupling portion17aon the upper portion of the front wall17 of the gutter. The intermediate body portion31 extends substantially perpendicular from thefirst coupling portion33 rearwardly to thebase portion32. It is understood that the connection between thefirst coupling portion33 and the gutter front wall may be accomplished through other means, including snap-in, physical interference, inter-fitting, interlocking, rotational engagement, use of a fastener, or use of adhesives.
• The[0014]fastening device15 both locates and directs an attachment fastener34, such as a screw, that extends through ahole35 inbase portion32 and a hole in thegutter back wall18. This function is accomplished by thehole35, a circular or linear detent in the base portion of the fastening device, a longitudinal channel (either open or closed) through which the fastener must pass, or simply a target marked on the base portion. This feature may direct thefastener34 perpendicular to the gutter back wall, or at some predetermined angle to thegutter back wall18.
• The[0015]fastening device15 is located in a preselected position relative to thegutter back wall18. Thebase portion32 abuts against the gutter back wall at a selected vertical location. The fastening device may be located relative to the gutter back wall in a variety of ways. Thefastening device15 shown has a groove or detent36 in the rear face that inter-fits with a forwardly protrudingridge37 formed in thegutter back wall18. Single or multiple grooves may be used. The lower edge of thefastener34, or a downward extension of the base portion may rest at the bottom of the gutter. The upper edge of thefastener34, or an extension of the base portion may rest on or be aligned with the top of thegutter back wall18. These variations may be used individually and in any combination to locate thefastening device15 relative to thegutter back wall18.
• The[0016]fastening device15 rigidly positions the shield front portion, thereby locating the shield front portion relative to the gutter front wall17. This relative positioning of the shield front portion and the gutter front wall upper portion facilitates both the drainage of water off the shield into the gutter and the blocking of debris from entry into the gutter.
• The[0017]fastening device15 has asecond coupling portion38 that rigidly inter-fits with the shield front coupling portion29. The connection betweensecond coupling portion38 and the shieldfront coupling portion27 may be accomplished through any of the following means: snap-in, physical interference, inter-fitting, inter-locking, rotational engagement, use of a fastener, or use of adhesives.
• The[0018]fastening device15 rigidly positions the shield rear coupling portion28, locating the shield rear coupling portion relative to both the gutter back wall and the shield front coupling portion. The relative positioning of the convexly curved shield rear coupling portion and the convexly curved shield front portion orients the shield to receive water run-off from the roof, directing the water towards either the front or rear portion of the shield. The relative positioning of the shield rear portion and the gutter back wall facilitates both the drainage of water off the shield into the gutter and the blocking of debris from entry into the gutter. More particularly the rear drainage feature is provided by the convexly curvedrear section23 along radius R2 and the coupling portion28 of the shield, together to the location relative to the back of the gutter and the shield rear portion and construction of thethird coupling portion39 that fits in coupling portion28. This facilitates having water runoff from the roof striking the shield, drain past the rear of the shield, and over the rear of thethird coupling portion39 of the fastening device.
• The[0019]fastening device15 has athird coupling portion39 that rigidly inter-fits with the shield rear coupling portion28. The connection between the fastening devicethird coupling portion39 and the shield rear coupling portion may be accomplished through any of the following means: snap-in, physical interference, inter-fitting, inter-locking, rotational engagement, use of a fastener, or use of adhesives.
• The[0020]second coupling portion38 andthird coupling portion39 shown are configured to provide a clip-in fit in the shield into the fastening device. As shown,coupling portions38 and39 have a circular cross section that are complimentary in shape to a socket of a circular cross section on the shield. In an alternative embodiment, the shield front and rear portions could fit outside the fastening device second and third coupling portions as was shown in U.S. Pat. No. 5,845,435 above marked. In this case, the shield front and rear portions would be flexed outward to engage the fastening device second and third coupling portions.
• The above discussed[0021]fastening device15 has a rigid intermediate body portion31 to which thebase portion32,first coupling portion33,second coupling portion38, andthird coupling portion39 are rigidly attached. Thefastening device15 is preferably made as a rigid one-piece integral body from a molded plastic material. Thefastening device15 has coupling portions that are configured to maximize its load bearing capacity. An alternate embodiment may be configured to provide angled or leveraged support for the upper portion of the gutter front wall. Conventional gutter hangars and spikes and ferrules rely on the gutter itself for any kind of angled support or bracing of the gutter front wall.
• Referring now to FIG[0022]4. an alternative embodiment of afastening device45 shown has abase portion52 and anintermediate body portion51 angled downward and rearward from the front orfirst coupling portion35 to the bottom of thebase portion52 to provide increased support for the gutter front wall. Thedetent56 and thehole55 in thebase portion52 are a greater a distance below thethird coupling portion39 than that described in thefastening devie15 above described. Theintermediate body portion51 provides the same body type of support for thesecond coupling portion38 and the shield front portion. This embodiment of the fastening device makes the system less prone to load-induced failures. Thehole55 for locating thefastener34 may be arranged as far up as thethird coupling portion39, maximizing the structural leverage of the fastening device.
• The[0023]base portion52 may be further configured to assist a user in the installation of flashing or drip edge at the eave. The base portion abuts against the gutter back wall, and may lie against the gutter back wall as high as thethird coupling portion39. However, thebase portion52 need only abut against the gutter back wall as high as the fastener location. Although some structural leverage may be sacrificed, thehole55 and screw fastener may be located substantially lower that thethird coupling portion39. In this case, a gap between the rear portion and the gutter back wall may exist above the hole and fastener. This gap would allow flashing and/or drip edge to be installed behind part of the fastening device. This offers much more flexibility in correctly pitching the gutter for water flow by providing additional space for flashing and/or drip edge.
• Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example and that changes in details of structure may be made without departing from the spirit thereof.[0024]
