Abstract
Abstract A resilient traffic standard or bumper includes a dome of resilient material having a central tubular section oriented orthogonally to the support surface and within which tubular section is disposable any one of a number of different types of standards. The outside of the central tubular section is surrounded by a compression spring which helps to restore the resilient dome to its undeformed shape after it has been impacted by a vehicle. The entire structure is anchored to the support surface through the bottom of the central tubular sections. A plurality of resilient domes are stackable and securable together for anchoring to a wall to function as a resilient bumper.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A resilient dome device comprising in combination, (a) a hollow dome made of resilient material, said dome having a top and a base, (b) a central tubular formation of resilient material secured to and extending vertically centrally downward from the top of the dome substantially to the base of the dome, said tubular formation being open at its upper end and through the top of the dome and downward through at least most of its vertical extent, whereby said tubular formation is adapted to receive within it a cylindrical member projected thereinto, (c) a spring disposed about the outer surface of and extending substantially the full length of the said central tubular formation thereby helping to restore the resilient dome to its undeformed shape, and (d) means for connecting said device to a supporting surface against which said dome base is disposable.
Claim 2
Dependent Claim
142 words
A resilient dome device comprising in combination, (a) a hollow dome made of resilient material, said dome having a top and a base, (b) a central tubular formation of resilient material secured to and extending vertically centrally downward from the top of the dome substantially to the base of the dome, said tubular formation being open at its upper end and through the top of the dome and downward through at least most of its vertical extent, whereby said tubular formation is adapted to receive within it a cylindrical member projected thereinto, (c) a spring disposed about the outer surface of and extending substantially the full length of the said central tubular formation thereby helping to restore the resilient dome to its undeformed shape, and (d) means for connecting said device to a supporting surface against which said dome base is disposable.
Claim 3
Dependent Claim
17 words
A resilient dome device as described in claim 1 wherein said hollow dome is hemisphere-like in shape.
Claim 4
Dependent Claim
24 words
A resilient dome device as described in claim 1 wherein said spring is a helical compression spring disposed closely about said central tubular formation.
Claim 5
Dependent Claim
39 words
A resilient dome device as described in claims 1, 2 or 3 wherein said connecting means comprises means for anchoring the lower end of said central tubular formation to a supporting surface against which said dome base is disposable.
Claim 6
Dependent Claim
34 words
At least two resilient dome devices as described in claim 1 arranged in a dome-to-base stacked array further including coupling means for operatively securing said resilient domes to one another in said stacked array.
Claim 7
Dependent Claim
42 words
A stacked array of resilient domes as described in claim 5 wherein said coupling means comprises means disposed within and translatable within the central tubular formation of each resilient dome device which has its dome secured to the base of another dome.
Claim 8
Dependent Claim
40 words
A stacked array of resilient domes as described in claim 5 wherein said coupling means comprises reciprocatable means disposed within the central tubular formation of each resilient dome device which has its dome secured to the base of another dome.
Claim 9
Dependent Claim
34 words
At least two resilient dome devices as described in claim 3 arranged in a dome-to-base stacked array further including coupling means for operatively securing said resilient domes to one another in said stacked array.
Claim 10
Dependent Claim
45 words
A stacked array of resilient domes as described in claims 5, 6, 7 or 8 further including support surface means secured to and interposing each adjacent pair of resilient dome devices and against which said surface the base of one of said domes is disposed.
Claim 11
Dependent Claim
36 words
A resilient dome device as described in claims 1 or 3 wherein said spring includes means at its lower end for fixedly securing said spring to a supporting surface against which said dome base is disposable.
