Abstract
Abstract An elongated bumper or curbing unit fabricated from poured concrete or the like for installation in multiples to provide a wall or border consisting of a series of individual units arranged and interconnected in an end-to-end relationship. Each curbing unit includes a vertically disposed cylindrical aperture formed adjacent each end thereof and a vertical slot connecting each of the apertures with its adjacent end. The curbing units are securely anchored to the ground and interconnected to each other by elongated generally U-shaped channel members which are inserted into the slots and apertures of adjacent curbing units and have a portion driven into the ground.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
260 words
A parking lot barrier comprising a plurality of curbing units joined in an end-to-end fashion, each of said curbing units comprising: an elongated member having a base and parallel end walls projecting upwardly therefrom to the upper surface of said member, each end wall of said member being identical and having a first vertically disposed slot extending through said member from the upper surface to the base thereof, said first slot opeNing to said end wall throughout its entire length, and a second vertically disposed slot inwardly spaced from said end wall and extending downwardly from said member upper surface, second slot, having a vertical surface offset from said first slot, said second slot communicating with said end wall through said first slot; each of said units being positioned on its base with its end walls facing the end walls of adjacent units such that said units are aligned in and end-to-end fashion; elongated anchoring members, one such anchoring member engaging said first and second slot in each of said adjacent units to secure said adjacent units in said end-to-end fashion, said anchoring members each comprising a metal, channel shaped member having a medial portion and flanged side portions, said medial portion extending through said first slots of adjacent units and said flanged side portions being disposed in said second slots of said adjacent units, said channel shaped member being longer than the height of said units and having its lower end pointed to penetrate the ground and thereby attach said units one to the other and to the ground.
Claim 2
Dependent Claim
260 words
A parking lot barrier comprising a plurality of curbing units joined in an end-to-end fashion, each of said curbing units comprising: an elongated member having a base and parallel end walls projecting upwardly therefrom to the upper surface of said member, each end wall of said member being identical and having a first vertically disposed slot extending through said member from the upper surface to the base thereof, said first slot opeNing to said end wall throughout its entire length, and a second vertically disposed slot inwardly spaced from said end wall and extending downwardly from said member upper surface, second slot, having a vertical surface offset from said first slot, said second slot communicating with said end wall through said first slot; each of said units being positioned on its base with its end walls facing the end walls of adjacent units such that said units are aligned in and end-to-end fashion; elongated anchoring members, one such anchoring member engaging said first and second slot in each of said adjacent units to secure said adjacent units in said end-to-end fashion, said anchoring members each comprising a metal, channel shaped member having a medial portion and flanged side portions, said medial portion extending through said first slots of adjacent units and said flanged side portions being disposed in said second slots of said adjacent units, said channel shaped member being longer than the height of said units and having its lower end pointed to penetrate the ground and thereby attach said units one to the other and to the ground.
Claim 3
Dependent Claim
97 words
The parking lot barrier defined in claim 1, wherein said second slot extends through said member from the upper surface of said member to the base thereof, the cross-sectional area of said first and second slots at said upper surface being at least equal to, but not less than the cross-sectional area of said first and second slots at said base such that said elongated anchoring members are adapted to be inserted in the first and second slots at the upper surfaces of said adjacent units and extend downwardly therethrough to join said units to one another.
Claim 4
Dependent Claim
21 words
The unit as defined in claim 1, wherein said second slot includes a vertically disposed cylindrical aperture extending through said member.
