Abstract
Abstract A protective traffic barrier designed to divert motor vehicle traffic away from an object or roadway is disclosed. A base with wedge-shaped projections extending vertically from the base impedes the movement of a motor vehicle across the barrier. The shape of the base may be designed to fulfill a particular function including an opening to allow the barrier to fit over an object to be protected. A resilient, preferably plastic, cover encapsulating the base protects people or animals from contact injury with the wedge-shaped projections while allowing the projections to penetrate a vehicle tire. The cover may be coated with various materials to enhance visibility of the barrier by motor vehicle operators.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
97 words
A protective traffic barrier comprising: (a) a generally square planar base having a top and a bottom; (b) a generally circular opening proximate said base center, said circular opening having a radius generally two-thirds the distance from center to base outer edge; and, (c) a plurality of wedge-shaped projections concentrically arranged between said opening's perimeter and said base outer edge and extending upward from said top, whereby when said barrier bottom is placed on a ground surface with said opening over an object projecting up from the ground, said barrier protects said object from vehicular tire damage.
Claim 2
Dependent Claim
97 words
A protective traffic barrier comprising: (a) a generally square planar base having a top and a bottom; (b) a generally circular opening proximate said base center, said circular opening having a radius generally two-thirds the distance from center to base outer edge; and, (c) a plurality of wedge-shaped projections concentrically arranged between said opening's perimeter and said base outer edge and extending upward from said top, whereby when said barrier bottom is placed on a ground surface with said opening over an object projecting up from the ground, said barrier protects said object from vehicular tire damage.
Claim 3
Dependent Claim
41 words
The protective traffic barrier according to claim 1 including, additionally, a resilient, high visibility cover, said cover having a top to encapsulate said projections and a bottom with a plurality of feet to hold said traffic barrier onto the ground surface.
Claim 4
Dependent Claim
86 words
A protective traffic barrier comprising: (a) a generally planar unitary base having an upperside and a lower side and an opening proximate said base center; and, (b) a plurality of triangular wedge-shaped projections concentrically arranged between said base outer edge and said opening perimeter, said projections extending upward from said base's upper side, whereby, when said base is placed on a ground surface with said opening placed over an object projecting upward from said ground surface, said traffic barrier protects said object from vehicular tire damage.
Claim 5
Dependent Claim
86 words
A protective traffic barrier comprising: (a) a generally planar unitary base having an upperside and a lower side and an opening proximate said base center; and, (b) a plurality of triangular wedge-shaped projections concentrically arranged between said base outer edge and said opening perimeter, said projections extending upward from said base's upper side, whereby, when said base is placed on a ground surface with said opening placed over an object projecting upward from said ground surface, said traffic barrier protects said object from vehicular tire damage.
Claim 6
Dependent Claim
15 words
A protective traffic barrier according to claim 3 wherein said planar base is generally square.
Claim 7
Dependent Claim
14 words
A protective traffic barrier according to claim 3 wherein said opening is generally circular.
Claim 8
Dependent Claim
25 words
A protective traffic barrier according to claim 5 wherein said opening has a radius generally two-thirds the distance from center to said base outer edge.
Claim 9
Dependent Claim
50 words
A protective traffic barrier according to claim 3 including, additionally, a resilient cover of an overall size and shape so that it encapsulates said base overfitting said wedge-shaped projections and the edge of said opening, thereby protecting people and animals from potential injury inflicted by contact with said wedge-shaped projections.
Claim 10
Dependent Claim
27 words
A protective traffic barrier according to claim 7 wherein said resilient cover includes high visibility color coating to enhance visual detection of said barrier by vehicle operators.
Claim 11
Dependent Claim
26 words
A protective traffic barrier according to claim 7 wherein said cover includes photoreflective coating to enhance visual detection at night of said barrier by vehicle operators.
Claim 12
Dependent Claim
31 words
A protective traffic barrier according to claim 7 wherein said cover includes a bottom, said cover bottom including a plurality of feet to hold said traffic barrier on the ground surface.
Claim 13
Dependent Claim
28 words
A protective traffic barrier according to claim 10 wherein said base is recessed to permit said resilient cover to rest on said cover bottom, thereby encapsulating said base.
Claim 14
Dependent Claim
16 words
A protective traffic barrier according to claim 3 wherein said base is fabricated from steel plate.
Claim 15
Dependent Claim
26 words
A protective traffic barrier according to claim 3 wherein said wedge-shaped projections are formed from V-shaped cuts from said base bent transversely to project vertically upward.
