ABSTRACT:
TECHNICAL FIELD
The present invention relates to anti-clog devices for building gutters and downspouts and more particularly to an adjustable downspout screening device that includes a two-part, adjustable width, screening cage having a forward screen cage portion and a back screen cage portion; the forward screen cage portion including a tubular shaped downspout insert cage secured to a bottom edge thereof and a number of insertion fingers; one insertion finger extending concentrically outward from each of every forward portion end cross members and forward portion top cross members; the back screen cage portion including two securing screws and a number of insertion finger receiving tubes equal to the number of insertion fingers forming an end of each of the back portion end cross members and back portion top cross members; each insertion finger receiving tube being sized and positioned to slidingly receiving therein the entire length of one of the insertion fingers simultaneously with the remainder of the insertion finger receiving tubes; each of the two securing screws threadably engaging one of insertion finger receiving tubes for providing a securing force against the side of an insertion finger sufficient to maintain the insertion finger within the insertion finger receiving tube at a desired user selected position such that the width of the two-part, adjustable width, screening cage is adjustable to the required width for insertion into the gutter section positioned above a downspout gutter connecting opening.
BACKGROUND ART
Gutter and downspouts often become clogged with leaves and other debris preventing them from working to channel the water off of a roof or the like to a desired drainage location. It would be a benefit, therefore, to have an adjustable downspout screening device that was width adjustable to allow the adjustable downspout screening device to be used with a variety of gutter and downspout sizes.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide an adjustable downspout screening device that includes a two-part, adjustable width, screening cage having a forward screen cage portion and a back screen cage portion; the forward screen cage portion including a tubular shaped downspout insert cage secured to a bottom edge thereof and a number of insertion fingers; one insertion finger extending concentrically outward from each of every forward portion end cross members and forward portion top cross members; the back screen cage portion including two securing screws and a number of insertion finger receiving tubes equal to the number of insertion fingers forming an end of each of the back portion end cross members and back portion top cross members; each insertion finger receiving tube being sized and positioned to slidingly receiving therein the entire length of one of the insertion fingers simultaneously with the remainder of the insertion finger receiving tubes; each of the two securing screws threadably engaging one of insertion finger receiving tubes for providing a securing force against the side of an insertion finger sufficient to maintain the insertion finger within the insertion finger receiving tube at a desired user selected position such that the width of the two-part, adjustable width, screening cage is adjustable to the required width for insertion into the gutter section positioned above a downspout gutter connecting opening.
Accordingly, an adjustable downspout screening device is provided. The adjustable downspout screening device includes a two-part, adjustable width, screening cage having a forward screen cage portion and a back screen cage portion; the forward screen cage portion including a tubular shaped downspout insert cage secured to a bottom edge thereof and a number of insertion fingers; one insertion finger extending concentrically outward from each of every forward portion end cross members and forward portion top cross members; the back screen cage portion including two securing screws and a number of insertion finger receiving tubes equal to the number of insertion fingers forming an end of each of the back portion end cross members and back portion top cross members; each insertion finger receiving tube being sized and positioned to slidingly receiving therein the entire length of one of the insertion fingers simultaneously with the remainder of the insertion finger receiving tubes; each of the two securing screws threadably engaging one of insertion finger receiving tubes for providing a securing force against the side of an insertion finger sufficient to maintain the insertion finger within the insertion finger receiving tube at a desired user selected position such that the width of the two-part, adjustable width, screening cage is adjustable to the required width for insertion into the gutter section positioned above a downspout gutter connecting opening.
