Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A speed bump for use on a road for imparting a controlled jar to a vehicle as the tires of said vehicle pass thereover comprising: an elongated flexible housing having a length sufficient to extend across a portion of a road to cover a path traveled by vehicles; an elongated chamber carried in said housing; fluid carried in said elongated chamber; means for securing said elongated flexible housing to said road; said elongated housing projecting vertically above said road and being compressible by a tire of said vehicle as said tire passes thereover for displacing said fluid under said tire from said chamber; and means for retarding the displacement of said fluid from said chamber and the compression of said housing at a controlled rate as said tire of said vehicle passes over said elongated flexible housing.
Claim 2
Dependent Claim
137 words
A speed bump for use on a road for imparting a controlled jar to a vehicle as the tires of said vehicle pass thereover comprising: an elongated flexible housing having a length sufficient to extend across a portion of a road to cover a path traveled by vehicles; an elongated chamber carried in said housing; fluid carried in said elongated chamber; means for securing said elongated flexible housing to said road; said elongated housing projecting vertically above said road and being compressible by a tire of said vehicle as said tire passes thereover for displacing said fluid under said tire from said chamber; and means for retarding the displacement of said fluid from said chamber and the compression of said housing at a controlled rate as said tire of said vehicle passes over said elongated flexible housing.
Claim 3
Dependent Claim
102 words
The speed bump as set forth in claim 1 further comprising: said means for retarding the displacement of said fluid including: an elongated plate carried within said elongated flexible housing dividing said elongated chamber into an upper and lower chamber; said fluid being carried in said lower chamber and air is provided in said upper chamber; openings provided in said elongated plate for permitting said fluid in said lower chamber to flow into said upper chamber at a controlled rate responsive to the pressure of the tire of the vehicle engaging said elongated flexible housing for controlling the compression of said housing.
Claim 4
Dependent Claim
50 words
The speed bump as set forth in claim 1 further comprising: said means for securing said elongated flexible housing to said road including: (i) opposed outwardly extending flanges provided adjacent a lower portion of said housing; and (ii) fastening means extending through said flanges securing said housing to said road.
Claim 5
Dependent Claim
65 words
The apparatus as set forth in claim 1 further comprising: said means for retarding the displacement of said fluid including: (i) a vertically extending housing; (ii) conduit communicating between said elongated flexible housing and said vertically extending housing; and (iii) a piston provided in said vertically extending housing which is raised responsive to fluid being forced from said elongated flexible housing into said vertical housing.
