Railing system

Claim 2

A railing system adapted for use adjacent the edge of a masonry floor, said railing system comprising: (a) at least one L-shaped post means having a vertical section and a horizontal section at the lower end thereof extending perpendicular to said vertical section, said horizontal section adapted to extend a distance beneath said masonry floor, (b) means adapted to secure said horizontal section to said masonry floor, (c) an elongated top rail secured intermediate the ends thereof to said vertical section, (d) an elongated bottom rail secured intermediate the ends thereof to said vertical section, said top and bottom rails being spaced apart and parallel to each other, and (e) a plurality of spaced apart picketts extending between and secured at the ends thereof to said top and bottom rails.

Claim 3

A railing system as set forth in claim 1 wherein said top and bottom rails each include a central member substantially I-shaped in cross-section for increased rigidity.

Claim 4

A railing system adapted for use adjacent the edge of a masonry floor, said railing system comprising: (a) at least one L-shaped post means having a vertical section and a horizontal section at the lower end thereof extending perpendicular to said vertical section, said horizontal section adapted to extend a distance beneath said masonry floor, and secured thereto, (b) elongated top and bottom rails secured to said vertical section in parallel, spaced apart relationship to each other, said top and bottom rails each comprising an inner plate member attached to said post, said inner plate member including a pair of parallel, spaced apart arms extending therefrom each arm of which has a lip defining a longitudinally extending recess, a central member being substantially I-shaped in cross-section, said central member having first and second oppositely disposed, spaced apart pairs of projections, each of said projections further having a pair of ribs extending from the ends thereof forming a longitudinally extending slot therebetween, said slots of said ribs of said first pair of projections being adapted to receive said lips of said inner plate member in sliding engagement therewith, and an outer plate member having parallel spaced-apart legs extending therefrom including a shoulder for and engaging said ribs on said second pair for locking same, and (c) a plurality of spaced apart picketts extending between and secured at the ends thereof to said top and bottom rails.

Claim 5

A railing system adapted for use adjacent the edge of a masonry floor, said railing system comprising: (a) at least one L-shaped post means having a vertical section and a horizontal section at the lower end thereof extending perpendicular to said vertical section, said horizontal section adapted to extend a distance beneath said masonry floor, and secured thereto, (b) elongated top and bottom rails secured to said vertical section in parallel, spaced apart relationship to each other, said top and bottom rails each comprising an inner plate member attached to said post, said inner plate member including a pair of parallel, spaced apart arms extending therefrom each arm of which has a lip defining a longitudinally extending recess, a central member being substantially I-shaped in cross-section, said central member having first and second oppositely disposed, spaced apart pairs of projections, each of said projections further having a pair of ribs extending from the ends thereof forming a longitudinally extending slot therebetween, said slots of said ribs of said first pair of projections being adapted to receive said lips of said inner plate member in sliding engagement therewith, and an outer plate member having parallel spaced-apart legs extending therefrom including a shoulder for and engaging said ribs on said second pair for locking same, and (c) a plurality of spaced apart picketts extending between and secured at the ends thereof to said top and bottom rails.

Claim 6

A railing system as set forth in claim 3 wherein said pickets extend between and are attached to said inner plate members of said top and bottom rails.

Claim 7

A railing system as set forth in claim 3 wherein said top and bottom rails are secured to said post means by support arms connected at one end thereof to said inner plate members and at the other end thereof to said post means.

Claim 8

A railing system as set forth in claim 5 wherein said post means is made of steel and said support arms are made of aluminum and said system further comprises insulation means between said support arms and said post means to eliminate the occurence of electrolysis.

Claim 9

A railing comprising: (a) a central member substantially I-shaped in cross-section, said central member having an inner portion with ends terminating at flange portions extending transverse to said inner portion, each of said flange portions having first and second oppositely disposed, spaced apart pairs of projections on the ends thereof forming longitudinally extending recesses therebetween, (b) a lower plate member including oppositely disposed arms extending therefrom, each of said arms having a lip for insertion into said recesses formed by said projections of said first pair, and (c) an upper plate member having parallel, spaced apart legs including a shoulder for engaging said second pair of projections.

Claim 10

A railing comprising: (a) a central member substantially I-shaped in cross-section, said central member having an inner portion with ends terminating at flange portions extending transverse to said inner portion, each of said flange portions having first and second oppositely disposed, spaced apart pairs of projections on the ends thereof forming longitudinally extending recesses therebetween, (b) a lower plate member including oppositely disposed arms extending therefrom, each of said arms having a lip for insertion into said recesses formed by said projections of said first pair, and (c) an upper plate member having parallel, spaced apart legs including a shoulder for engaging said second pair of projections.
