  • Patent number: 4047703
    Abstract: A rattle-free rail construction includes a plurality of vertical line posts, each having an H cross-sectional configuration defining vertical channels in the post. Each channel includes a pair of opposed, vertically extending arcuate grooves which are of the correct diameter to properly accept self-tapping screws. Another pair of opposed, vertically extending retention grooves are disposed in each channel, parallel and adjacent to the arcuate grooves. Horizontal bars of the railing construction are secured with the ends thereof in opposed channels of adjacent line posts, the bars being spaced apart in each channel by post inserts which snappingly engage the retention grooves in the channel. Double-sided foam tape is applied to the top and bottom ends of the horizontal bars, and the entire assembly is secured in a channel by joining a top subrail onto top of post by means of screws received into the top openings of the arcuate grooves.

  • Patent number: 4000883
    Abstract: A railing construction comprises a laterally disposed sub rail member which supports a top rail, and a support bracket at either end of the sub rail for securing the sub rail to a wall or post. The bracket includes a generally vertically disposed member which is provided with a bolt hole through the upper end thereof. A pair of generally parallel web members extend normally from the lower end of the vertical member, the lower web member extending farther outward and including an obliquely upwardly extending flange at the distal end thereof. The slot between the two web members is adapted to receive the sub rail therein only when the bracket is canted downwardly toward the sub rail. As a bolt passed through the bolt hole is tightened into a wall or post, the canted bracket approaches vertical, and the flange and the lower surface of the upper web lever the sub rail into rigid engagement.
