Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
94 words
An electrically pressure sensitive edge structure adapted for a door, said structure comprising a channel extending along a door facing outwardly therefrom, internal projections in said channel, and an entirely resiliently compressible pressure sensitive assembly of foam material snugly engaged longitudinally in said channel, said assembly including a base portion substantially completely occupying said channel, said base portion being sufficiently laterally compressible for edgewise engagement into and withdrawal from said channel past said internal projections, and an active portion extending outwardly from said channel, said assembly being formed with recesses releasably receiving said projections.
Claim 2
Dependent Claim
94 words
An electrically pressure sensitive edge structure adapted for a door, said structure comprising a channel extending along a door facing outwardly therefrom, internal projections in said channel, and an entirely resiliently compressible pressure sensitive assembly of foam material snugly engaged longitudinally in said channel, said assembly including a base portion substantially completely occupying said channel, said base portion being sufficiently laterally compressible for edgewise engagement into and withdrawal from said channel past said internal projections, and an active portion extending outwardly from said channel, said assembly being formed with recesses releasably receiving said projections.
Claim 3
Dependent Claim
78 words
A pressure sensitive edge structure according to claim 1, said internal projections comprising longitudinally extending ribs, said base portion comprising an elongate body of resiliently compressible foam material substantially completely occupying said channel compressible to pass transversely across and between said ribs, said recesses being defined by longitudinally extending grooves in opposite sides of said body, and said active portion comprising a pair of longitudinally extending flexible contact strips in facing spaced relation and depressible into contacting engagement.
Claim 4
Dependent Claim
36 words
A pressure sensitive edge structure according to claim 2, in combination with a cover of sheet material flexible to permit engagement of said projections in said grooves and depression of said strips into said contacting engagement.
