Abstract
A starter strip for anchoring, to a wall, the bottom margins of the lowermost course of an array of horizontally elongated siding panels each secured to the wall along its top margin and each having an inwardly projecting, upwardly opening channel flange along its bottom margin. The starter strip includes a leg mountable on the wall, a locking flange arranged to be received within the channel flanges of the panels, and resilient biasing means such as a spring leg for acting against the inner surfaces of the panels to urge the bottom margins of the panels outwardly and thereby to hold the inner legs of their channel flanges against the inner edge of the locking flange.
Claims6
For use with a wall-mounted array of overlapping parallel courses of horizontally elongated siding panels mounted one above another on a wall, each of said panels having outwardly and inwardly facing major surfaces, a top margin securable to the wall, and a bottom margin bent inwardly and upwardly to form an inwardly projecting, upwardly opening longitudinal channel flange with an upstanding inner leg, a starter strip for anchoring the bottom margin of at least one panel of the lowermost of the courses to the wall, said starter strip comprising:
- (a) a leg mountable on the wall;
- (b) a locking flange connected to the starter strip leg, positioned and dimensioned to be received in the channel flange of said one panel and having an inner dge, spaced from the starter strip leg, for bearing against the upstanding leg of the channel flange;
- and
- (c) resilient biasing means, receivable with the locking flange in the panel channel flange and disposed to act against the inwardly-facing surface of said one panel adjacent the bottom of the channel flange of the panel, for urging the last-mentioned panel surface outwardly, thereby to hold the upstanding leg of the panel chanel flange against said locking flange inner edge when the locking flange is received in the channel flange;
- (c) said biasing means comprising a depending spring leg having a free, outwardly projecting lower end for engaging the aforesaid inwardly-facing panel surface, said lower end of said spring leg being so disposed that said spring leg is compressed inwardly by the panel when said spring leg and said locking flange are received in the panel channel flange.
The combination, with at least one horizontally elongated siding panel mounted on a wall and having inwardly and outwardly facing major surfaces, a top margin secured to the wall, and a bottom margin bent inwardly and upwardly to form an inwardly projecting, upwardly opening longitudinal channel flange with an upstanding inner leg, of a starter strip anchoring the bottom margin of the panel to the wall, said starter strip comprising:
- (a) a leg mounted on the wall;
- (b) a locking flange connected to the starter strip leg, disposed in said panel channel flange and having an inner edge, spaced from the starter strip leg and from the wall, bearing against the upstanding leg of the channel flange, the width of said locking flange being less than the width of the channel flange;
- and
- (c) resilient biasing means, disposed under compression in the channel flange outwardly of the locking flange and acting against said inwardly-facing panel surface adjacent the bottom of the channel flange for urging the last-mentioned panel surface outwardly, thereby to hold the upstanding leg of the panel channel flange against said locking flange inner edge;
- (d) said biasing means cpmprising a depending spring leg having a free, outwardly projecting lower end for engaging the aforesaid inwardly-facing panel surface, said lower end of said spring leg being so disposed that said spring leg is compressed inwardly by the panel when said spring leg and said locking flange are received in the panel channel flange.
