Claims
- 1. A surface bearing, comprising a plate made of resilient elastomer material interspersed with a plurality of hollow channels and cavities intersected by said channels, all of said hollow channels and cavities in said plate lying in a single plane extending at least essentially parallel to a principal load bearing surface of the plate or complementary in shape to the principal surface, each said cavity intersected by only one of said hollow channels, wherein none of the hollow channels intersect each other and said hollow channels are open at least at one end thereof, wherein a plurality of groups of said hollow channels are aligned so as to extend in each group parallel to one another in the elastomer matrix, wherein the imaginary extensions of the central axes of said hollow channels of different groups intersect one another without the hollow channels themselves intersecting.
- 2. The surface bearing of claim 1, wherein said channels have a cross-section which is at least about 1/4 of the size of the largest cross-sectional area of the nearest cavity intersected by said associated hollow channel.
- 3. A surface bearing, comprising a plate made of resilient elastomer material interspersed with a plurality of hollow channels and cavities intersected by said channels, all of said hollow channels and cavities in said plate lying in a single plane extending at least essentially parallel to a principal load bearing surface of the plate or complementary in shape to the principal surface, each said cavity intersected by only one of said hollow channels, wherein none of the hollow channels intersect each other and said hollow channels are open at least at one end thereof, wherein said plate is regular polygonal or circular in plan view, and at least some of said hollow channels are formed so as to be open at only one end and are aligned so as to extend radially towards the center of the sheet material without intersecting or touching in the center, wherein an opening, which can be formed like a through opening or closed on one side in the manner of a blind hole or a groove, extends in the center of the plate sheet material in a direction normal to the principal surface.
- 4. The surface bearing of claim 3, wherein all said hollow channels are formed so as to extend radially towards the center of the sheet material without intersecting or touching in the center.
- 5. The surface bearing of claim 3, wherein said channels have a cross-section which is at least about 1/4 of the size of the largest cross-sectional area of the nearest cavity intersected by said associated hollow channel.
