Abstract
Abstract This invention consists of a method and components for the construction of railing in general, and balcony railing, in particular. The railing which is of the usual type, having an upper hand rail and a bottom base or footrail with equally spaced baluster bars in between, is constructed so that all parts are joined and held together by means of pressure applied to these parts, which causes them to snap into one another. This is possible to accomplish due to the resilient character of the materials or metals used in the construction of the railing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
224 words
The construction of railing for use on balconies and other similar installations, by means of components which snap and hold together by the application of pressure, comprising a handrail which consists of a slightly convex handrail cover, of a width to provide a hand grip, the ends of said cover being bent downwardly and at a small angle inwardly, into two opposite handrail walls, which are further bent inwardly into short horizontal bends; a handrail base which attaches to said handrail cover, consisting of a flat plate, a pair of short, vertical, cover-holding hooks attached to the upper face of said plate, facing away from each other, and each hook being located near each of the sides of said baseplate; a pair of spaced, vertical, inwardly facing hooks also attached to the upper face of said base plate, located symmetrically between the said cover-holding hooks, and extending slightly above them; a plurality of uniformly spaced holes provided in said baseplate for the passage therethrough of the upper end of each baluster; a footrail constructed substantially the same as the said handrail, with the exception that the baluster penetration holes are provided in the cover plate instead of the baseplate; and a plurality of vertical balusters, each having two opposite flat walls, provided with horizontal channels into which hook the baluster hooks of the baseplate.
Claim 2
Dependent Claim
224 words
The construction of railing for use on balconies and other similar installations, by means of components which snap and hold together by the application of pressure, comprising a handrail which consists of a slightly convex handrail cover, of a width to provide a hand grip, the ends of said cover being bent downwardly and at a small angle inwardly, into two opposite handrail walls, which are further bent inwardly into short horizontal bends; a handrail base which attaches to said handrail cover, consisting of a flat plate, a pair of short, vertical, cover-holding hooks attached to the upper face of said plate, facing away from each other, and each hook being located near each of the sides of said baseplate; a pair of spaced, vertical, inwardly facing hooks also attached to the upper face of said base plate, located symmetrically between the said cover-holding hooks, and extending slightly above them; a plurality of uniformly spaced holes provided in said baseplate for the passage therethrough of the upper end of each baluster; a footrail constructed substantially the same as the said handrail, with the exception that the baluster penetration holes are provided in the cover plate instead of the baseplate; and a plurality of vertical balusters, each having two opposite flat walls, provided with horizontal channels into which hook the baluster hooks of the baseplate.
Claim 3
Dependent Claim
180 words
The construction and components of railing such as described in claim 1, with the addition of panelling to said railing, comprising in combination a handrail such as described in claim 1; a panel-holding bracket consisting of a U-shaped channel, for inserting therein one of the edges of a rectangular panel; an open top and bottom box attached to one side of said U-shaped channel, for containing therein the upper or lower end of each baluster; some of said baluster containing boxes being provided with a closed top by means of which said U-shaped bracket is attached to the baseplate of the handrail, with the said U-shaped channel of the bracket pointing downwardly; a similar bracket, located where the footrail would normally be, and replacing said footrail, and having its U-shaped channel pointing upwardly; a U-shaped filler fitting tightly into each of said bracket channels; a U-shaped rubber insert located and held within each of said fillers; and a rectangular panel of glass or an opaque material whose upper and lower edges are located within and held by said rubber inserts.
