Filed Oct. 12, 1964, Ser. No. 403,100 2 Claims. (Cl. 256-22) This invention relates to an ornamental metal railing construction, and more particularly relates to an adjustable railing, extruded from metal such as aluminum, which can be shipped in knockdown folded sections for later assembly at the site from selected lengths and there automatically oriented to accommodate for any slope of steps or pitch of ground.
In the past, ornamental railing constructions did not lend themselves to convenient shipment and handling because either the sections from which the ultimate railing was to be assembled could not be collapsed into an eflicient size or the elements were so disassembled as to require an expert for erection at the site. Furthermore, the hitherto prefabricated metal railing sections were not easily adapted to allow adjustability for various angles of pitch or inclination of steps and ground contour at the erection site. Finally, these prior railing systems required so much erector hardware, such as nuts, bolts, screws, as to give them a most unsightly external appearance rather than desirable smooth, free-flowing ornamental lines.
It is therefore an object of this invention to provide a prefabricated, knockdown, ornamental metal railing construction which may be conveniently shipped in a package of small girth, and which may be readily and quickly assembled by an unskilled person at the site.
Another object of this invention is to provide an ornamental metal railing construction in which the pickets are securely fastened to the rails by concealed means, and in which there are no exposed bolts, rivets, screws or other parts to obstruct the smoothness of the erected railing.
Another object of this invention is to provide an ornamental metal railing construction which is fabricated from interchangeable fully-collapsible modular folding sections whereby the assembled railing may be adjustably pivoted to enable its erection upon variable ground inclinations or step slopes.
Still another object of this invention is to provide an ornamental railing construction in which all rail stringer elements have longitudinally slidable caps to conceal the picket pivotal connections and also to permit adjacent modular sections to be adjoined telescopically without seams.
Other objects of this invention are to provide an improved device of the character described which is easily and economically produced, which is sturdy in construction, and highly eflicient and effective in operation.
With the above and related objects in view, this invention consists of details of construction and combination of parts as will be more fully understood from the following detailed description when read in conjunction with the accompanying drawings, in which:

FIGURE 10 is a fragmentary side elevational view of a modified form of this invention.
FIGURE 11 is a sectional view taken along lines 1111 of FIGURE 10.
Referring now in greater detail to the drawings in which similar reference characters refer to similar parts, I show an adjustable knockdown railing construction comprising a plurality of pickets or spindles A which are pivotally connected at their upper and lower ends to a longitudinally-extending top rail member B and a bottom rail member C thereby defining a modular section which is free to assume any parallelogram configuration. Each modular folding section may thus be assembled at the site, as shown in FIGURE 1, intermediate vertical posts 12 and 14 to provide a horizontally extending portion above patio 17 or intermediate posts 14 and 16 to yield an inclined portion over steps 15. 7 As is also readily apparent, each section can be prefabricated at the plant and shipped in fully collapsed position within cartons of minimal girth.
The pickets A are extruded tubular aluminum elements, preferably of rectangular cross-section, having aligned pairs of openings 18 in opposed side walls adjacent each end. In the embodiment shown in FIGURES 1 to 9, the rail members B and C include pairs of inner stringers 20 which are longitudinally-extending extruded angles of L- As best illustrated in FIGURES 2 and 9, each stringer 20 has a vertical flange portion 21 with longitudinally-spaced dimpled or countersunk holes 22 which register with the openings 18 in the side walls of the pickets A and a horizontal flange portion 23 which projects outwardly when the top and bottom ends of pickets are sandwiched between opposing stringer pairs. Rivets 24 are passed through the respective aligned openings 18 and inwardly dimpled holes 22 and have upset heads 25 which seat within the countersunk dimples so as to be substantially flush with the outer faces of the stringer vertical flanges 21. The rivets 24 thereby provide a plurality of pivot points about which the pickets A are hingedly constrained in a parallelogram linkage.
Referring now to FIGURES 2 and 8, the bottom rail member C also includes a longitudinally-extending cap 28 of generally U-shaped section which is slidably received upon the lower pair of stringers 20 so as to conceal the rivet heads 25. The cap 28 is normally of a length coextensive with that of the stringers 20 of a prefabricated section although it may be equal to two or more sections and telescopically couple longitudinally abutting stringers and cover the abutment line. Cap member 28 is also an extruded aluminum component and comprises a pair of vertical side flanges 30 interconnected by a bight web 32. The ends of the side flanges 30 have outwardly formed decorative projections 34 with interior opposed longitudinally-extending slots 36. See FIGURE 8. When the cap 28 is inserted over the lower stringers 20, the slots 36 slidably embrace the oppositely disposed horizontal flanges 23 while the side flanges 3% are guided over the outer faces of the stringers vertical flanges 21 and encapsulate the rivet heads from view.
In a similar manner, the upper rail member B includes a handrail cap extrusion 38 of generally inverted U-shaped cross-section wherein a pair of laterally spaced flanks 40 downwardly project from a fluted baluster web 42. As is best illustrated in FIGURES 2 and 9, the handrail cap 38 has a pair of opposed interior longitudinallyextending recesses 44 which are slidably received upon the complementary outwardly-extending horizontal flanges 23 of the upper pair of stringers 20. The flanks 40 embrace the outer faces of the stringers vertical flanges 21 to hide the pivot joints 24 from view while the baluster web portion 42 eflectively conceals the upper ends of the pickets A themselves. It is also to be noted that the length of the handrail cap 38 may be co-extensive with that of the stringer 20 of a single modular section or it may be of suflicient length to support and combine two or more abutting sections without exhibiting the abutting seams. See FIGURE 9.
The posts 12, 14 and 16 are also preferably of rec-- tangular tubular extrusions and are mounted upon complementary bases 46 which are secured to steps or the patio 17 by suitable bolts 48. See FIGURES 6 and 7. Detachable end caps 50 telescopically interfit within the upper portions of the posts and may be of various ornamental configuration to suit the taste of the user. Finally, end brackets D are employed to assemble the sections of the railing to the posts.
The end brackets D comprise a cylindrical portion 52 which is received in the channel between the pairs of spaced stringers 20 at the ends of the rail members B and C and a flat tall 54 which is secured to the posts by self-threading screws 56. See FIGURES 4 and 5. Selfthreading screws 58 which extend through aligned apertures in the respective rail members and the cylindrical portion 52 couple the modular sections to the brackets D and hence to the various posts. Note the modular sections are free to orient themselves about their parallelogram pivots so as to assume the angle of inclination desired.
In FIGURES 10 and 11, there is shown a modified railing construction comprising a medial rail member E and the bottom rail C between which the pickets A are pivotally supported in a parallelogram linkage, and design scroll means F affixed between the medial rail E and a top or handrail member G.
The construction of the bottom rail C is exactly the same as that described under the two-rail modular section, and the lower end of each of the pickets A is embraced by a pair of stringers 20 through the dimpled holes 22 of which the rivets 24 provided the pivotal joints. Once again, the lower cap 28 is slidably received upon the lower stringer pair to cover the rivet heads 25. However, the medial rail E, while it includes a pair of stringers 20 which sandwich the upper ends of the pickets A with pivotal rivet joints 24, the stringers 20 are now inverted so that their laterally-extending horizontal flanges 23 project from the lower portion of the vertical flanges 21. The rivet heads 25 are still recessed within the inwardly dimpled holes 22 of the vertical flanges 21, and the pivotal mounting is as before.
Instead of a handrail cap 38 being slidably received on the upper stringers Ztl, a second cap member 28 is employed except that the U-channel is inverted and the bight web 32 now overlies the top of the pickets A. However, the slots 36 still telescopically embrace the horizontal flanges 23, and the side flanges 30 cover the vertical flanges 21 to conceal the rivet heads 25. The bight web 32 is now adapted to support the scroll means F as will now be described.
The scroll means F generally comprises lengths of aluminum bar stock which is formed into designs of various convolutions. Such scroll work is well known in the art, but in the instant application the height at the maximal portions is retained relatively constant, perhaps six inches as an example. In the embodiment illustrated, the scroll F takes the form of a rather elaborate M whose legs 59 are curled inwardly to provide a base for support. Sheet metal screws 60 pass through apertures in the legs 59 and threadedly engage longitudinally-spaced registering apertures in the bight web 32 of cap member 28. The screws 60 project downwardly into the space between the upper pair of stringers 20 without intruding with the tops of pickets A or their pivotal connections.
In a similar manner, the mantles 62 of the scroll F are secured by sheet metal screws 60 to the bight portion 65 of U-shaped channel member 64- through respective aligned apertures therein. The channel member 64 includes a pair of laterally-spaced sides 66 upwardly extending from the bight portion 65. Outwardly turned horizontal lips 68 are formed on the sides 66 and define horizontal tracks for slidably receiving the recesses 44 in handrail cap 38 of top handrail member G. It is to be observed that the baluster web 42 now overlies the channel member 64 and conceals the screws 60 upwardly projecting therein.
The scroll means F may either be prefabricated upon the medial cap 28 and the upper channel member 64- at the plant and then slidably incorporated as a unitary assembly over the upper stringers 241 at the site of installation, or they may be mounted individually upon the medial rail E after the lower pivotally coupled railing section is in place. As before, the three-rail modular sections, which include the scroll means F, are secured to the vertical posts 12, 14 and 16 by coupling the end brackets D to the terminals of the handrail member G, the medial rail member E and the bottom rail member C.
It is thus evident that the railing construction of the instant invention is well adapted for convenient shipment of modular sections in packages of small size, and thereafter easily asembled at the site to suit the inclination of the ground or slope of the steps. Furthermore, the telescoping cap members 28 and 38 fully conceal all seams and rivet, bolt and screw connections, which would otherwise present an unsightly appearance, so as to provide a smooth design that does not detract from the overall ornamental configuration.
Although this invention has been described in considerable detail, such description is intended as being illustrative rather than limiting since the invention may be variously embodied and the scope of the invention is to be determined as claimed.
