Surface positioning for compressible seal arrangement

摘要

A mechanical assembly including a pair of members each having a planar surface and a displacing structure can be designed to engage a compressible seal, and thereby reduce or eliminate shear force exerted on the seal, keeping the seal intact during compression. Each displacing structure can have a displacing surface and a latching surface. A compressible seal can be affixed to one of the planar surfaces. Contact between the displacing surfaces during parallel movement of the planar surfaces relative to each other may create a separation between the planar surfaces greater than the compressible seal height. Positioning of the displacing surfaces past each other during parallel movement of the planar surfaces relative to each other may initiate the compression of the compressible seal between the planar surfaces.

1. An apparatus comprising:
a first member with a first planar surface and a first displacing structure with a first displacing surface and a first latching surface; a second member with a second planar surface a second displacing structure with a second displacing surface and a second latching surface; a compressible seal affixed to the second planar surface; wherein the first and second displacing structures are adapted so that contact between the first and second displacing surfaces during a parallel movement of the first planar surface relative to the second planar surface creates a separation between the first and second planar surfaces greater than a height of the compressible seal, and so that positioning of the first and second displacing surfaces past each other during parallel movement of the first planar surface relative to the second planar surface initiates the compression of the compressible seal between the first and second planar surfaces.
