Abstract

Abstract An improved shock absorbing bumper is provided for use on automobiles and the like in which, in one form, a backing plate supports an elastomeric body or pad having at its front a plurality of longitudinally extending elastomeric tubes. The tubes nest within corrugations of a corrugated panel which, upon being struck, compresses the tubes and elastomeric body during movement of the panel toward the back or support plate. Preferably, an elastomeric cover substantially encompasses the body, tubes, and corrugated panels and has terminal portions secured to the support plate. The tubes are preferably closed at their ends and may contain rubber pellets, liquids, compressed gas, and the like.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 98 words
A bumper construction comprising a longitudinally extending support plate, a resilient compressible elastomeric body secured with respect to said plate and extending lengthwise thereof, a plurality of hollow, compressible members fixed with respect to said elastomeric body and extending lengthwise thereof in substantially parallel relation, a corrugated panel overlying the hollow members and having corrugations to engage said members and to compress said members and elastomeric body upon movemEnt of the panel toward said support plate, and an elastomeric cover substantially encompassing said body, hollow members, and corrugated panel and having terminal portions secured to said support plate.
Claim 2
Dependent Claim 98 words
A bumper construction comprising a longitudinally extending support plate, a resilient compressible elastomeric body secured with respect to said plate and extending lengthwise thereof, a plurality of hollow, compressible members fixed with respect to said elastomeric body and extending lengthwise thereof in substantially parallel relation, a corrugated panel overlying the hollow members and having corrugations to engage said members and to compress said members and elastomeric body upon movemEnt of the panel toward said support plate, and an elastomeric cover substantially encompassing said body, hollow members, and corrugated panel and having terminal portions secured to said support plate.
Claim 3
Dependent Claim 23 words
The bumper construction of claim 1 in which said support plate has outwardly extending flanges which engage the sides os said elastomeric body.
Claim 4
Dependent Claim 15 words
The bumper construction of claim 2 in which said flanges abut against the corrugated panel.
Claim 5
Dependent Claim 39 words
The bumper construction of claim 2 in which the outer ends of said flanges are turned toward one another and overlie adjacent edges of the corrugated panel to retain said panel, hollow members, and elastomeric body between said flanges.
Claim 6
Dependent Claim 44 words
The bumper construction of claim 1 including bolt means extending from the corrugated panel through said support plate, said bolt means accommodating movement of said panel, hollow members, and elastomeric body toward the support plate while restricting movement thereof away from the support plate.
Claim 7
Dependent Claim 22 words
The bumper construction of claim 1 in which said hollow members are elastomeric tubes sealed at their ends and containing elastomeric pellets.
Claim 8
Dependent Claim 24 words
The bumper construction of claim 1 in which said hollow members are elastomeric tubes sealed at their ends and incompletely filled with a liquid.
Claim 9
Dependent Claim 24 words
The bumper construction of claim 1 in which said hollow members are elastomeric tubes sealed at their ends and containing a gas under pressure.
Claim 10
Dependent Claim 18 words
The bumper construction of claim 8 in which said tubes have valve means to admit gas under pressure.
Claim 11
Dependent Claim 19 words
The bumper construction of claim 1 in which said hollow members are elastomeric tubes adhered to said elastomeric body.
Claim 12
Dependent Claim 21 words
The bumper construction of claim 1 including a second corrugated panel interleaved between said elastomeric body and said hollow compressible members.
Claim 13
Dependent Claim 25 words
The bumper construction of claim 1 in which said hollow, compressible members are tubes, and one tube has a diameter greater than the other tubes.
Claim 14
Dependent Claim 15 words
The bumper construction of claim 1 in which said compressible elastomeric body comprises foamed rubber.
Claim 15
Dependent Claim 33 words
The bumper construction of claim 1 in which said hollow members are elastomeric, and the elastomer of said cover has a hardness exceeding that of the elastomers of said body and hollow members.
Claim 16
Dependent Claim 19 words
The bumper construction of claim 1 in which said elastomeric body has grooves to receive said hollow compressible members.
