Abstract:
A modular fence assembly, comprising:a. a pair of vertical four-sided tubular posts being adaptable to be secured to a support surface; b. a plurality of spaced apart horizontal four-sided tubular rails, each rail extending transversely to and secured between said pair of vertical tubular posts, each rail having a plurality of equally spaced apart four-sided through apertures therein centered on a longitudinal axis of said each rail where the respective apertures of the plurality of horizontal rails are aligned; c. a plurality of vertically disposed four-sided tubular pickets arranged in mutually parallel relationship between and extending through respectively aligned ones of said plurality of apertures of said plurality of horizontal tubular rails, each picket having at least two locations along the length of said each picket corresponding to a respective two of said plurality of horizontal tubular rails, a respective transverse slotted aperture extending therethrough perpendicularly to the longitudinal axis of the picket; d. a one-piece flat generally H-shaped locking means having a middle section and two leg sections located on opposite sides of the middle section, a respective H-shaped locking means inserted into said each transverse slotted aperture of said picket such that the middle section is located within an interior of said each transverse slotted aperture of said picket and the two leg sections are extending outside of said each transverse slotted aperture; and e. said plurality of vertically tubular pickets being respectively in said plurality of apertures of said plurality of horizontal tubular rails wherein said plurality of tubular pickets are axially movable in said plurality of apertures of said horizontal rails to a locking position at which said leg sections of said respective H-shaped locking means in said each transverse slotted aperture of said picket engage said respective two of said plurality of horizontal tubular rails and further axial movement of said plurality of tubular pickets relative to said plurality of horizontal tubular rails is prevented.
