Abstract
A plastic modular fence system having posts, a first rail, a second rail, and upright picket boards extending between the rails. A plurality of mounting brackets each have a T-shaped opening for receiving an end of one of the rails therein and an edge of a picket therein. The bracket opening extends through the peripheral wall in places to allow the edge of the picket to extend out of the bracket on opposite sides. Also, the rails have openings configured to receive the generally vertical picket boards when the rails are positioned either horizontally or at an angle to the horizon. For example, the openings in the intermediate rail have a generally trapezoidal shape with one opening end longer than the other opening end.
Claims28
A modular fence system comprising:
- a pair of upright posts;
- a first upper rail, a second lower rail, and a third intermediate rail, each of the rails having a plurality of openings defined therein;
- and
- a plurality of upright picket boards extending from the second lower rail to the third intermediate rail to the first upper rail and received into the openings in the rails, wherein each of the rail openings has a length sufficiently greater than a width of the picket boards such that the picket boards can be received into the rail openings with the rails being disposed either horizontally or at an angle relative to horizontal and the picket boards maintained generally vertical, wherein each of the openings in the intermediate rail has a generally trapezoidal shape defined in part by a first opening end and a second opening end that is longer than the first opening end by a distance of about (a) (tangent θ) where (a) is the thickness of the rail and (θ) is the maximum angle of the rail relative to horizontal, wherein the openings in the intermediate rail include a first or last opening at an end portion of the rail and the second end of the first or last opening extends through the end portion of the rail;
- and
- a plurality of mounting brackets secured to the posts to receive and secure end portions of the rails therein, each of the brackets also being adapted to receive an edge of one of the upright picket boards therein to secure the edge of the upright picket board near one of the upright posts, wherein the brackets each include peripheral walls defining an opening, wherein the bracket opening is generally T-shaped and formed by a first generally rectangular opening portion and a second generally rectangular opening portion, the first generally rectangular opening portion being about twice as wide as the second generally rectangular opening portion, wherein the bracket opening extends through the peripheral wall in places to allow the edge of the upright picket board to extend out of the bracket on opposite sides.

A modular shadow box style fence system comprising:
- a first upper rail and a second lower rail;
- a plurality of upright picket boards positionable extending from the second lower rail to the first upper rail and alternating front and back;
- and
- a plurality of mounting brackets each having peripheral walls defining an opening with a rail opening portion adapted to receive and secure end portions of the rails therein and with a picket opening portion adapted to at the same time receive an edge of one of the upright picket boards therein, wherein said picket opening portion is positioned off-center of said rail opening portion so that the picket received in said off-center picket opening portion can be a front or back one.

- a plurality of upright picket boards positionable extending from the second lower rail to the first upper rail;
- and
- a plurality of mounting brackets each including peripheral walls defining a generally T-shaped opening adapted to receive and secure end portions of the rails therein and to also receive an edge of one of the upright picket boards therein, wherein the generally T-shaped opening includes a first generally rectangular opening portion and a second generally rectangular opening portion.
1 more element
A modular fence system comprising:
- a first upper rail and a second lower rail;
- a plurality of upright picket boards positionable extending from the second lower rail to the first upper rail;
- and
- a plurality of mounting brackets each including peripheral walls defining a generally T-shaped opening adapted to receive and secure end portions of the rails therein and to also receive an edge of one of the upright picket boards therein, wherein an interior of the bracket opening is wider than an end of the opening at a front surface of the bracket.
1 more element
A modular fence system comprising:
- at least two rails, each one of the rails having a plurality of openings defined therein;
- and
- a plurality of upright picket boards each positionable extending between the rails and through the corresponding openings of at least one of the rails, wherein each rail opening receives only one of the picket boards,
- wherein each of the rail openings has a length sufficiently greater than a width of the picket boards such that the picket boards can be received into the rail openings with the rails being disposed either horizontally or at an angle relative to horizontal, and the picket boards maintained generally vertical.
