  • Patent number: 4986513
    Abstract: A fence and connector assembly having connector brackets mounted near the top and bottom of the fence posts, each bracket having a vertical sleeve and side flange members spaced to receive the ends of rails therebetween, and L-shaped bracket securing and rail mounting studs between the flange members. The rails have limited pivotal movement on the distal ends of these studs to accommodate uneven terrain, and are secured thereon by spring retainers within the rails.Between the vertically spaced, generally horizontal rails are vertical rungs, each having its lower end in an aperture in the lower hollow rail and its upper end in an aperture into the upper hollow rail. Locking rods extend through the rails and through these transverse apertures adjacent the ends of the rungs, securing the rungs to the rails.

  • Patent number: 4982933
    Abstract: A fence adapted for mounting on level or uneven terrain includes generally vertical posts, generally horizontal hollow rails, and connector clips for attaching the rails to the posts. The connector clips are received within the inner cavity of the hollow rails and include an elongated opening which is adapted to receive therethrough a stud attached to the vertical post. About the opening and within the rail is provided a retaining structure which facilitates easy insertion of the stud, at various angles, but securely resists withdrawal thereof. The length of the opening is substantially greater than the width of the stud received therethrough, so that deviations of the post from a true vertical position and/or deviations of the rail from a true horizontal position in the erection of the fence on an uneven terrain may be accommodated.
