Lateral displacement shock absorbing material
View Patent ↗A lateral displacement shock absorbing material includes a material consisting of elongated tubular impact absorbing members, each having an axis of elongation. The axes of elongation are parallel to one another by virtue of lateral webbing interconnecting them together. Each of the tubular members has an outer surface made up of two frustoconical surfaces with their larger diameter ends abutting one another and their smaller diameter ends facing away from one another. Each tubular member includes a passageway defined by two frustoconical shapes with the smaller diameter ends abutting one another, and the larger diameter ends facing away from one another and defining the openings of each passageway. Upon impact, the side walls of the tubular members bulge or displace laterally to absorb impacts.
1. A shock absorbing material, comprising:
a) a plurality of tubular members spaced apart, each tubular member including:
i) an axis of elongation;
ii) an internal passageway having an inner surface and extending through a said tubular member from a first end of said tubular member to a second end thereof, said inner surface comprising two abutting frustoconical surfaces with relatively smaller first terminations abutting;
iii) an outer surface having varying cross-sectional dimensions from said first end to said second end, said outer surface comprising two abutting frustoconical surfaces with relatively larger diameter first terminations abutting one another; and
b) means for maintaining said axes of elongation of said tubular members in substantially parallel alignment.
2. The material of claim 1 , wherein said frustoconical surfaces of said outer surface have relatively smaller diameter second terminations coinciding with said first and second ends, respectively.
3. The material of claim 1 , wherein said frustoconical surfaces of said internal passageway have relatively larger diameter second terminations coinciding with said first and second ends, respectively.
4. The material of claim 1 , wherein said means for maintaining comprises webbing laterally interconnecting adjacent tubular members.
5. The material of claim 4 , wherein each tubular member has a plurality of webbings extending laterally therefrom.
6. The material of claim 4 , comprising at least five tubular members including a central tubular member, four peripheral tubular members and webbing interconnecting said central tubular member to each peripheral tubular member.
7. The material of claim 1 , made of molded plastic.
8. The material of claim 1 , made of rubber.
9. The material of claim 1 , wherein said frustoconical surfaces define with an axis of elongation a taper of 1-45°.
10. A shock absorbing material, comprising:
a) a plurality of tubular members spaced apart, each tubular member including:
i) an axis of elongation;
ii) an internal passageway having an inner surface and extending through a said tubular member from a first end of said tubular member to a second end thereof, said inner surface comprising two abutting frustoconical surfaces with relatively smaller first terminations abutting;
iii) an outer surface extending from said first end to said second end; and
b) means for maintaining said axes of elongation of said tubular members in substantially parallel alignment, said means for maintaining comprising webbing laterally interconnecting adjacent tubular members.
11. The material of claim 10 , wherein said two abutting frustoconical surfaces have relatively larger diameter terminations coinciding with said first and second ends, respectively.
12. The material of claim 10 , wherein each tubular member has a plurality of webbing extending laterally therefrom.
