Abstract
Abstract An elongated, tubular, sealing strip or member of resilient, flexible elastomeric material such as neoprene is provided with a top wall having a central portion formed as a V with a wide angle between the arms, and a pair of main reinforcing webs extending longitudinally within said tubular strip and respectively extending diagonally from the top wall of said strip adjacent one side edge thereof to the bottom wall of the strip adjacent the opposite side wall of the strip. Said reinforcing webs intersect and are joined together substantially at the intersection of an imaginary vertical plane equidistant from the side walls and an imaginary horizontal plane cutting the side walls at approximately their midpoints. Additional supplementary, reinforcing webs extend diagonally from approximately the midpoints of the side walls normal to the lower portions of the main webs.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
222 words
A flexible, resilient, sealing strip adaptd for sealing a slot between adjacent faces of rigid bodies and maintaining a sealing relation during changes in width of said slot resulting from expansion and contraction of said bodies which comprises: an elongated, tubular member having spaced side walls that are approximately straight and parallel; a top wall joining the upper edges of said side walls, said top wall having edge portions substantially normal to said side walls and an inner, central portion having in cross-section a downwardly pointed V-shape; a bottom wall joining the lower edges of said side walls; a pair of elongated ,intersecting, main reinforcing webs within said tubular member, each of said main webs extending diagonally from one of said normal portions of said top wall to said bottom wall adjacent the opposite side wall and intersecting substantially at the intersection of a vertical plane equidistant from the side walls of said strip and a horizontal plane cutting said side walls at their mid-points; and a pair of elongated supplementary reinforcing webs within said tubular member, each of said supplementary webs extending diagonally downward from an intermediate point on one of said side walls to the adjacent main web only, said strip being free from webs in the space between said main webs and below the intersection of said main webs.
Claim 2
Dependent Claim
222 words
A flexible, resilient, sealing strip adaptd for sealing a slot between adjacent faces of rigid bodies and maintaining a sealing relation during changes in width of said slot resulting from expansion and contraction of said bodies which comprises: an elongated, tubular member having spaced side walls that are approximately straight and parallel; a top wall joining the upper edges of said side walls, said top wall having edge portions substantially normal to said side walls and an inner, central portion having in cross-section a downwardly pointed V-shape; a bottom wall joining the lower edges of said side walls; a pair of elongated ,intersecting, main reinforcing webs within said tubular member, each of said main webs extending diagonally from one of said normal portions of said top wall to said bottom wall adjacent the opposite side wall and intersecting substantially at the intersection of a vertical plane equidistant from the side walls of said strip and a horizontal plane cutting said side walls at their mid-points; and a pair of elongated supplementary reinforcing webs within said tubular member, each of said supplementary webs extending diagonally downward from an intermediate point on one of said side walls to the adjacent main web only, said strip being free from webs in the space between said main webs and below the intersection of said main webs.
