Fence Safety and Anti-Theft System
Patent Number: US 11002038 Grant Date: 2021-05-11 Filing Date: 2017-10-30
Overview
Filed on October 30, 2017 and granted on May 11, 2021, this patented perimeter enhancement protects existing fence segments by adding horizontal beveled rails that eliminate grab points and discourage climbing. Inventors based in Lubbock, TX devised a solution that mounts to standard horizontal rails and pickets: the bottom of the beveled rail seats on the horizontal rail while the back attaches to the pickets, and the sloped face is intentionally neither horizontal nor vertical to prevent easy hand- or footholds. The claims capture both unibody and segmented constructions, modular tab-and-slot joinery for field-adjustable lengths, and multiple manufacturing routes—carved wood, extrusion, injection molding, or composite—preserving functionality across materials and production methods.
The firm’s patent drafting emphasizes practical installability and manufacturing breadth: prosecution secured language covering bevel angles, planar relationships (bottom as a horizontal plane; back as a vertical plane), and segment-level features (horizontal and vertical apertures, mating tabs/slots) to maximize enforceability and retrofit applicability for residential and commercial fences.
Key Features
- Retrofit-compatible beveled rail that mounts to existing rails and pickets
- Beveled face geometry engineered to inhibit climbing
- Modular segments with tab-and-slot assembly for standard lengths
- Multiple material and manufacturing embodiments (wood, extrusion, injection-mold)
- Claims covering unibody and segmented constructions
By protecting a design that is both manufacturable and straightforward to install, this patent supports improved perimeter security across landscaping, building materials, and fence-manufacturing industries.
Invention Details
Abstract: Safety rail assemblies comprise horizontal beveled rails having a beveled face, a width, a height, a bottom, a back, and a bevel angle. The safety rail assemblies are configured to selectively attach to horizontal rails and pickets of one or more fence segments. The bottom of the safety rail assemblies attaches to a top of the horizontal rails. The back of the horizontal beveled rails attaches to the pickets. The bottom is a horizontal plane. The back is a vertical plane. The beveled face comprises the bevel angle and represents a face of the horizontal beveled rails being non-horizontal and non-vertical between the back and the bottom.
Summary of the Invention: A safety rail assemblies for improving a one or more fence segments. Said safety rail assemblies comprising a beveled face, a width, a height, a bottom, a back, a bevel angle. Said safety rail assemblies configured to selectively attach to a horizontal rails and a pickets of said one or more fence segments. Said bottom of said safety rail assemblies attaches to a top of said horizontal rails. Said back of a horizontal beveled rails attaches to said pickets. Said bottom is a horizontal plane. Said back is a vertical plane. A beveled face comprises said bevel angle and represents a face of said horizontal beveled rails being non-horizontal and non-vertical between said back and said bottom.

A beveled face comprises said bevel angle and represents a face of said horizontal beveled rails being non-horizontal and non-vertical between said back and said bottom. Said safety rail assemblies is attached to said pickets with said beveled face facing upward to prevent easy climbing of said one or more fence segments. Said safety rail assemblies comprise a one or more segments. Each among said one or more segments are configured to selectively break apart into separate and similar parts. Said one or more segments comprise at least a first segment and a second segment.
