Abstract
Abstract A safety edge construction for a door including an edge plate coextensive with a door edge and having one surface facing away from the door, the edge plate being formed in its outer surface with an undercut longitudinal groove, a pressure sensitive inner body extending along the groove, and a stiff flexible attachment member secured to the body and having a rib conformably engaged in the groove for retention of the body against separation from the plate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
183 words
A door safety edge comprising a door edge plate for longitudinal extension along a door edge and having an outer surface facing away from the door, said door edge plate having its outer surface generally flat, there being at least one longitudinally extending groove in said outer edge plate surface, said groove having opposite internal undercuts, a resiliently compressible preSsure sensitive inner body extending longitudinally along said edge plate adjacent to said groove, a casing of flexible sheet material covering said inner body, an attachment member of relatively stiff flexible material secured to said body adjacent to the door, and at least one relatively stiff rib on said attachment member and located in said groove, said rib including lateral extensions engaged in said undercuts for retention against separation from said plate, said attachment member being generally flat and secured in facing relation with said inner body interposed between the latter and said edge plate, said outer edge plate surface having an access passageway communicating with said groove adjacent to and spaced inwardly from one groove end for passing said rib into said groove.
Claim 2
Dependent Claim
183 words
A door safety edge comprising a door edge plate for longitudinal extension along a door edge and having an outer surface facing away from the door, said door edge plate having its outer surface generally flat, there being at least one longitudinally extending groove in said outer edge plate surface, said groove having opposite internal undercuts, a resiliently compressible preSsure sensitive inner body extending longitudinally along said edge plate adjacent to said groove, a casing of flexible sheet material covering said inner body, an attachment member of relatively stiff flexible material secured to said body adjacent to the door, and at least one relatively stiff rib on said attachment member and located in said groove, said rib including lateral extensions engaged in said undercuts for retention against separation from said plate, said attachment member being generally flat and secured in facing relation with said inner body interposed between the latter and said edge plate, said outer edge plate surface having an access passageway communicating with said groove adjacent to and spaced inwardly from one groove end for passing said rib into said groove.
Claim 3
Dependent Claim
38 words
A door safety edge construction according to claim 1, said casing completely encompassing said body in sealing relation therewith, and said attachment member being secured to said casing in sealing relation with the latter about a closed configuration.
Claim 4
Dependent Claim
180 words
A door safety edge construction comprising a door edge plate for longitudinal coextension along a door edge and having an outer surface facing away from the door, said door edge plate having its outer surface generally flat, there being at least one longitudinally extending groove in said outer edge plate surface, said groove having opposite internal undercuts, a resiliently compressible pressure sensitive inner body extending longitudinally along said edge plate adjacent to said groove, a casing of flexible sheet material covering said inner body, an attachment member of relatively stiff flexible material secured to said body adjacent to said door, and at least one relatively stiff rib on said attachment member and located in said groove, said rib including lateral extensions engaged in said undercuts for retention against separation from said plate, said inner body, casing, attachment member and rib being a longitudinally flexible unit, and said outer edge plate surface having an access passageway communicating with said groove adjacent to and spaced inwardly from one groove end for passing said rib into said groove upon flexure of said unit.
Claim 5
Dependent Claim
180 words
A door safety edge construction comprising a door edge plate for longitudinal coextension along a door edge and having an outer surface facing away from the door, said door edge plate having its outer surface generally flat, there being at least one longitudinally extending groove in said outer edge plate surface, said groove having opposite internal undercuts, a resiliently compressible pressure sensitive inner body extending longitudinally along said edge plate adjacent to said groove, a casing of flexible sheet material covering said inner body, an attachment member of relatively stiff flexible material secured to said body adjacent to said door, and at least one relatively stiff rib on said attachment member and located in said groove, said rib including lateral extensions engaged in said undercuts for retention against separation from said plate, said inner body, casing, attachment member and rib being a longitudinally flexible unit, and said outer edge plate surface having an access passageway communicating with said groove adjacent to and spaced inwardly from one groove end for passing said rib into said groove upon flexure of said unit.
Claim 6
Dependent Claim
77 words
A door safety edge construction according to claim 3, there being an additional longitudinally extending undercut groove in said outer edge plate surface parallel to and spaced from said first mentioned groove, and an additional relatively stiff flexible rib on said attachment member parallel to and spaced from said frist mentioned rib and located in said additional groove, said first rib including lateral extensions engaged in said undercut additional groove for retention against separation from said plate.
Claim 7
Dependent Claim
32 words
A door safety edge construction according to claim 3, said attachment member being generally flat and secured in facing relation with said inner body interposed between the latter and said edge plate.
Claim 8
Dependent Claim
38 words
A door safety edge construction according to claim 3, said casing completely encompassing said body in sealing relation therewith, and said attachment member being secured to said casing in sealing relation with the latter about a closed configuration.
