Lock and key bonding system

Abstract

Interlocking bonding surfaces for use with bonding agents are disclosed having unique lock and key geometries that may be matched to each other in one or more ways. One part may have holes in a specific configuration while the matched part has protrusions or alternatively, one part may have both protrusions and holes that interlock with those of the other matching part. Such configurations provide a one way fit between parts in addition to providing authentication and control of specific components.

Claims

1. An interlocking bonding construction for providing a one way fit between two bonding surfaces comprising: a first bonding surface and a second bonding surface;said first bonding surface having a pattern of protrusions extending in an outward direction from said surface toward said second bonding surface and;said second bonding surface having holes;said holes of said second bonding surface being arranged in a matching pattern to said protrusions extending in an outward direction from said first bonding surface thereby providing a one way fit between said holes of said second bonding surface and said protrusions extending in an outward direction from said first bonding surface;a bonding agent such as epoxy;said protrusions extending in an outward direction from said first bonding surface having contact with said bonding agent and;said bonding agent having contact with said holes of said second bonding surface;wherein said protrusions extending outward from said first bonding surface extend into said holes of said second bonding surface.

2. An interlocking bonding construction for providing a one way fit between two bonding surfaces comprising: a first bonding surface and a second bonding surface;said first bonding surface having a pattern of protrusions extending in an outward direction from said surface toward said second bonding surface and;said second bonding surface having protrusions extending in an outward direction toward said first bonding surface;said protrusions extending in an outward direction from said second bonding surface being arranged and spaced in such a manner as to provide spaces between said protrusions extending in an outward direction from said second bonding surface in a matching pattern to said protrusions extending in an outward direction from said first bonding surface thereby providing a one way fit between said spaces between said protrusions of said second bonding surface and said protrusions extending in an outward direction from said first bonding surface;a bonding agent such as epoxy;said protrusions extending in an outward direction from said first bonding surface having contact with said bonding agent and;said bonding agent having contact with said spaces between said protrusions extending in an outward direction from said second bonding surface;wherein said protrusions extending outward from said first bonding surface extend into said spaces between said protrusions of said second bonding surface.
