In various examples, the present disclosure describes a railing system 10 including a positioning system for limiting movement between a rail and a baluster. Although the present disclosure provides examples, the disclosed methods and devices may be suitable for other purposes, with modification as appropriate.
The balusters are disposed between the rails 100, 200. In some embodiments, for example, the balusters extends from the rail 100 to the rail 200. Although two balusters 200 are shown disposed between the upper and lower horizontal rails 100, 300, it is understood that more balusters may be connected to and disposed between the upper and the lower rails 100, 300. In some embodiments, for example, the number of balusters is at least four (4), such as, for example, at least six (6), such as, for example, at least eight (8), such as, for example, at least ten (10). In some embodiments, for example, the spacing distance between the balusters 200 is the same or substantially the same. In some embodiments, for example, the balusters 200 are spaced apart by varied distances between them. In some embodiments, the balusters 200 extend vertically, or substantially vertically, between the rails 100 and 300.
In some embodiments, for example, each one of the rails 100, 200, independently, is generally elongated. In some embodiments, for example, each one of the rails 100, 200 includes a respective central longitudinal axis.
Referring to
In some embodiments, each one of the rail members 120, 140, independently, is made of plastic, such as high density polyethylene, polypropylene, polycarbonate, acrylonitrile butadiene styrene (ABS). In some embodiments, each one of the balusters, independently, is made of polyvinyl chloride. In some embodiments, each one of the rail members 120, 140, independently, is manufactured with an extrusion process to form a unitary one-piece construction. In some embodiments, for example, each one of the rail members 120, 140, independently, is an extruded plastic lineal. In some embodiments, for example, each one of the first rail member 120 and the second rail member 140, independently, is double-walled for increasing rigidity.
Referring to
In some embodiments, for example, an insert 130 is disposed within the cavity 160, and extends lengthwise of the first and second rail members 120, 140, for reinforcing the first and second rail members 120, 140. In some embodiments, for example, the insert 130 is made of any one of metal, plastic, or composite material. In some embodiments, the insert is made of metal. In some embodiments, for example, the insert 130 is made of steel or aluminum.
In some embodiments, for example, the insert 130 has a channel-shaped interior. The insert 130 includes a horizontal wall 131, a first sidewall 132, and a second sidewall 133. Each one of the sidewalls 132, 133, independently, has a recess 136 in the middle section for receiving the free ends 124 and 125 of the first rail member 120, for effecting coupling of the insert 130 to the rail member 120 (and, therefore, the rail 100) in an interference fit relationship. The sidewalls 132, 133 extend beyond the sidewalls 122, 123. The free ends 134, 135 of the sidewalls 132, 133, respectively, extend toward the channel. In some embodiments, an interference fit relationship is formed between the interior surfaces of the walls 142, 143 and the exterior surfaces of the upper portions of the sidewalls 132, 133, such that the reinforcing insert 130 structurally reinforces the sides of the second rail member 140. In some embodiments, an interference fit relationship is formed between the interior surfaces of the walls 122, 123 and the exterior surfaces of the lower portions of the walls 132, 133, such that the reinforcing insert 130 structurally reinforces the rail piece 120. In some embodiments, an interference fit relationship is formed between the interior surface of the wall 141 and the exterior surfaces of the free ends 134, 135 such that the reinforcing insert 130 structurally reinforces the top of the rail member 140. In some embodiments, an interference fit relationship is formed between the exterior surface of the wall 131 and the interior surface of the wall 121 such that the reinforcing insert 130 reinforces the bottom side of the first rail member 120. An example of the rail members 120, 140 engaging the insert 130 is illustrated in
In some embodiments, for example, the construction of the lower horizontal rail 300 is identical, or substantially identical, to the construction of the upper horizontal rail 100, and, in this respect, includes corresponding first and second rail members 320, 340 and insert 330 (see
The balusters 200 are configured for coupling to the rail 100, and also configured for coupling to the rail 300. In some embodiments, each one of the balusters, independently, is made of plastic, such as high density polyethylene, polypropylene, polycarbonate, acrylonitrile butadiene styrene (ABS). In some embodiments, each one of the balusters, independently, is made of polyvinyl chloride. In some embodiments, each one of the balusters, independently, is preferably manufactured with an extrusion process to form a unitary one-piece construction. In some embodiments, for example, each one of the balusters 200, independently, is an extruded plastic lineal.
For effecting the coupling of the balusters 200 to the rails 100, 300, each one of the rails 100, 300, independently, defines a respective positioning system. In some embodiments, for example, for each one of the rails 100, 300, the positioning system is defined by an elongated projection 110 (310) that extends from the respective rail 100 (300) and is receivable by the balusters 200. In some of these embodiments, for example, the projection 110 (or 310) is continuous and uninterrupted. In other embodiments, for example, the positioning system is defined by a plurality of discrete projections that extend from the respective rail 100 (300) and is receivable by the ballusters.
The first rail member 120 of the upper rail 100 includes an inwardly facing surface 150, and the projection 110 extends from the surface 150. In some embodiments, for example, the surface 150 is planar or substantially planar. In some embodiments, for example, the projection 110 extends longitudinally such that a longitudinal axis of the projection is parallel, or substantially parallel, to the central longitudinal axis of the first rail member 120. In some embodiments, for example, the projection 110 has a height of at least about 1/16 inches. In some embodiments, for example, the projection 110 has a height of between about 1/16 inches and about 2 inches. In some embodiments, for example, the projection 110 has a width of at least about ⅛ inches. In some embodiments, for example, the projection 110 has a width of between about ⅛ inches and about ¼ inches. In some embodiments, for example, the projection 110 has a length of at least about 12 inches. In some embodiments, for example, the projection 110 has a length of between about 12 inches and about 84 inches.
The first rail member 320 of the lower rail 300 includes an inwardly facing surface 350, and the projection 310 extends from the surface 350. In some embodiments, for example, the surface 350 is planar or substantially planar. In some embodiments, for example, the projection 310 is uninterrupted and continuous, and extends longitudinally such that a longitudinal axis of the projection is parallel, or substantially parallel, to the central longitudinal axis of the first rail member 320. In some embodiments, for example, the projection 310 has a height of at least about 1/16 inches. In some embodiments, for example, the projection 310 has a height of between about 1/16 inches and about 2 inches. In some embodiments, for example, the projection 310 has a width of at least about ⅛ inches. In some embodiments, for example, the projection 310 has a width of between about ⅛ inches and about ¼ inches. In some embodiments, for example, the projection 310 has a length of at least about 12 inches. In some embodiments, for example, the projection 310 has a length of between about 12 inches and about 84 inches.
In some embodiments, for example the projections 110, 310 are identical, or substantially identical. In some embodiments, for example, the projection 110 is of a different configuration relative to the projection 310.
Each one of the balusters 200, independently, is configured for receiving the projections 110, 310. In some embodiments, for example, the upper rail 100, the lower rail 300, and the balusters 200 are co-operatively configured such that, for each one of the balusters 200, the baluster 200 is configured to simultaneously receive both of the projections 110, 310. In this respect, in some embodiments, for example, each one of the balusters 200, independently, defines a space at its upper end 210 for receiving the upper projection 110, and also defines a space at its lower end 230 for receiving the lower projection 310.
In some embodiments, for example, for each one of the balusters 200, independently, the baluster 200 is configured to receive the projection 110 with effect that lateral displacement of the baluster 200, relative to the upper rail member 100, is restricted, and is also configured to receive the projection 310 with effect that lateral displacement of the baluster 200, relative to the lower rail member 300, is restricted. In some of these embodiments, for example, the lateral displacement is prevented or substantially prevented.
In some embodiments, for example, for each one of the balusters 200, independently, the baluster 200 is configured to receive the projection 110 with effect that rotation of the baluster 200 about its central longitudinal axis is restricted, and is also configured to receive the projection 310 with effect that rotation of the baluster 200 about its central longitudinal axis is restricted. In some embodiments, for example, the rotation is prevented or substantially prevented.

In some embodiments, for example, when the balusters 200 receive the the projections 110, for each one of the balusters 200, the upper end 210 of the baluster is disposed in contact engagement with the inwardly facing surface 150 of the rail member 120. Similarly, in some embodiments, for example, when the balusters 200 receive the projections 310, for each one of the balusters, independently, the lower end 230 of the baluster is disposed in contact engagement with the inwardly facing surface 350 of the rail member 320.
In some embodiments, for example, for each one of the balusters 200, independently, while: (i) the projection 110 is received by the baluster, and (ii) the projection 310 is received by the baluster 200, vertical displacement of the baluster 200, relative to the upper rail member 120, is restricted (and, in some embodiments, for example, opposed) by the upper rail member 120, and vertical displacement of the baluster 200, relative to the lower rail member 320, is limited (and, in some embodiments, for example, opposed) by the lower rail member 320.
In some embodiments, for example, for each one of the balusters 200, independently, while: (i) the projection 110 is received by the baluster, and (ii) the projection 310 is received by the baluster, the inwardly facing surface of the upper first rail member 120 is opposing the inwardly facing surface of lower first rail member 320.

The securement of one end of the upper rail 100 to the newel post 400, via the mounting bracket 500, will now be described. The mounting bracket 500 includes a generally planar first flange 502 oriented for being slidably received within corresponding channels defined within the upper rail 100. In some embodiments, for example, the upper rail 100 and the flange 502 are co-operatively configured such that the flange 502 is securable to the upper rail 100 with a fastener (such as, for example, a screw). The mounting bracket 500 further includes a generally planar second flange 504, joined to the first flange 502 and oriented vertically for securing the mounting bracket 500 to the newel post 400 via fasteners 506 (for example, screws) extending through apertures 508 defined within the second flange 504.
In some embodiments, for example, to assemble the railing system, each one of the balusters 200 is emplaced over a corresponding location on the projection 110 (or 310) of one of the upper first rail member 120 and the lower rail members 320 and fastened to the rail member 120 (or 320), to obtain an intermediate assembly. The projection 310 (or 110) of the other one of the rail members 320 (or 120) is then emplaced into the other end of the balusters 200 and fastened to balusters. Assembly of the rails 100, 200 is then completed, and this includes coupling the upper second rail member 140 to the upper first rail member 120 by way of snap fit engagement, and coupling the lower second rail member 340 to the lower first rail member 320 by way of snap fit engagement
