A railing system 110 in accordance with an example of one aspect of the Applicant's teaching can be seen in
Each of the rails 112a, 112b is generally elongate, having opposed ends adapted to be secured to uprights 118. The uprights 118 can be in the form of, for example, but not limited to, walls, columns, or posts. In the example illustrated, the uprights 118 are in the form of newel posts.
Referring now to
Each beam 122a, 122b comprises a proximal face 124 directed towards the balusters 116, and a distal face 126 opposite the proximal face 124. The upper and lower beams 122a, 122b can optionally have a common profile. In the example illustrated, the beams 122a, 122b have a common profile and are interchangeable with each other.
Each baluster 116 in the embodiment illustrated includes a hollow casing 130 and a brace 132 extending lengthwise within the casing 130. The casing 130 can be made of a material that is generally non-structural, and the casings 130 can provide cosmetic or other ancillary benefits to the railing system 110, rather than necessarily satisfying strength and/or other performance requirements. In the example illustrated, the casings 130 are made of polymer, such as an extruded vinyl.
Referring to
In the railing 110, the upper end 132a of each brace 132 is secured to the upper rail 112a and the lower end 132b of each brace 132 is secured to the lower rail 112b. In the example illustrated, the upper ends 132a of each brace 132 are secured to the upper beam 122a of the upper rail 112a, and the lower ends 132b of each brace 132 are secured to the lower beam 122b of the lower rail 112b.
To facilitate securing the braces 132 to the beams 122a, 122b, each brace 132 can have at least two brace screw bosses 134 at each end for anchoring a fastener 136 therein. More particularly, in the example illustrated, each brace 132 has two upper brace screw bosses 134a at the upper end 132a and two lower brace screw bosses 134b at the lower end 132b. The two screw bosses 134 can be spaced apart laterally by a brace screw boss spacing 137.
In the example illustrated, the brace screw bosses 122a, 122b are generally vertical and can comprise vertical channels 138 having open ends 138a, 138b adjacent the proximal surface 124 of the upper and lower beams 122a, 122b, respectively. The vertical channels 138 can extend continuously along the length of each brace 132.
Each beam 122a, 122b can have apertures in registration with the open ends of the brace screw bosses 134 for receiving the fasteners 136 therethrough. In the example illustrated, the upper beam 122a has upper apertures 140a and the lower beam 122b has lower apertures 140b. The apertures 140a, 140b can be spaced apart lengthwise along the length of the beam 122a, 122b by a lengthwise spacing 144, which can be selected to match the desired spacing between adjacent balusters 116. The two apertures in each pair of apertures can be spaced apart transversely by a transverse aperture spacing 147 that can be equal to the brace screw boss spacing 137.
The fasteners 136 can comprise screws with threaded shanks 150 and a head 152 at one end thereof. Upon assembly, the head 152 can bear against the distal face 126 of the beam 122a, 122b, drawing the beam 122a, 122b and baluster 116 securely together.
The rails 112a, 112b can be provided with a cover that can conceal and/or enclose the beam 122a, 122b. In the example illustrated, the upper rail 112a comprises an upper cover 156a generally covering the distal face 126 of the upper beam 122a, and the lower rail 112b comprises a lower cover 156b generally covering the distal face 126 of the lower beam 112b.
The covers 156a, 156b can be made of a material that is generally non-structural, and the covers can provide cosmetic or other ancillary benefits to the railing system 110, rather than necessarily satisfying strength and/or other performance requirements. In the example illustrated, the covers 156a, 156b are made of polymer, such as an extruded vinyl. The vinyl can provide a good gripping surface that remains warmer to the touch than would, for example, a metal cover.
The upper and lower covers 156a, 156b can optionally have a common profile. In the example illustrated, the upper cover 156a has a profile that is distinct from that of the lower cover 156b. The upper cover 156a has an outer surface 158a that is slightly more contoured (rounded) with recesses 160 on either side, which can facilitate being grasped by the hand of a user. The lower cover 156b has an outer surface 158b that is more rectangular (relative to the upper cover 156a).
The covers 156a, 156b can be coupled to the beams 122a, 122b, to the ends of the balusters 116, and/or to other elements of the rails 112a, 112b. In the example illustrated, the rails include retainers to which the covers 156a, 156b can be coupled. The upper rail 112a comprises an upper retainer 162a extending lengthwise of the upper rail 112a and disposed between the upper ends of the balusters 116 and the proximal surface 124 of the upper beam 122a. The lower rail 112b in the example illustrated comprises a lower retainer 162b extending lengthwise of the lower rail 112b and disposed between the lower ends of the balusters 116 and the proximal face 124 of the lower beam 122b.
Further details of the brace 132 will be described, with reference to
Each brace 132 has an outer surface 176, at least a portion of which is configured to engage at least a portion of the inner surface 178 of the casing 130 such that relative lateral movement between the casing 130 and the brace 132 is inhibited. In the example illustrated, the opposed ends 180 of the arms 172 provide a portion of the outer surface 176 of the brace 132 that engages an the inner surface 178 of a first pair of opposed sidewalls 182 of the casing, to inhibit motion in a first lateral direction (up-down direction in
The casing 130 can be provided with optional casing screw bosses 188 at each end, which can be engageable with the fastener 136 (or another fastener) to secure the casings 116 to the rails 112a, 112b. In the example illustrated, each casing 130 has two upper brace screw bosses 188a at the upper end and two lower casing screw bosses 188b at the lower end. The two screw bosses 188 at each end can be spaced apart by a casing screw boss spacing 187. The casing screw boss spacing 187 can be equal to the brace screw boss spacing 137. Providing equal screw boss spacing 137, 187 can facilitate installation of casings 130 without braces 132 in cases where braces are not required (for example, on ground floor railing installations). The casings 130 can then be universal, in the sense that the same extrusion can be used with or without braces 132. Rotating the casing 130 by 90 degrees (or inverting the casing 130 end-over-end by 180 degrees) can provide aligned registration of the casing screw bosses 188 with the apertures 140a, 140b in the beam 122a, 122b.
Referring to
The baluster 216 has a casing 230 and a brace 232. The brace 232 comprises, in the example illustrated, a generally planar central web 274 with brace screw bosses 234 extending along each opposed side edge. The brace 232 is sized to fit snugly within the casing on a diagonal, between opposed first and second corners 231a, 231b. The other two opposed interior corners 231c, 231d of the casing 230 are provided with casing screw bosses 288. The casing screw bosses 288 are spaced apart from each other by a casing screw boss spacing 287 which is equal to the casing boss spacing 237, and which defines a common screw boss diameter centered about a central longitudinal axis of the baluster 216, and about which the four screw bosses are equally spaced at 90 degree increments.
Referring to
In the baluster 316, the casing screw bosses 388 and the brace screw bosses 334 are not spaced equally apart. Installing the balusters 316 with the brace 332 requires a distinct aperture spacing 147 in the beam 122a, 122b to match the spacing 337 between the brace bosses 332. This can provide a failsafe and/or a visual indication as to whether or not a baluster 316 has been installed with or without a brace 332 in the casing 330.
Referring to
In the baluster 416, the casing 430 is provided with interior supports 491 for engaging the outer surface of the brace 432. In the example illustrated, the interior supports 491 have inner surfaces that engage opposing outer surfaces of each of the brace screw bosses 434, to inhibit lateral motion in one direction (left-right in
Referring to
In the baluster 516, the casing 530 is free of any casing screw bosses. The brace 532 has a web structure that is X-shaped in cross section, with four web segments 474a, 474b, 474c and 474d extending from a central axis 475, and a respective brace screw boss 434 provided along the side edge of each web segment. [0055] Another example of a railing system 610 is shown in

The railing system 610 further includes a lower rail 612b extending generally parallel to the upper rail 612a and spaced vertically below the upper rail 612b. The lower rail 612b includes a lower beam 622b constructed of metal. The lower beam 622b is, in the example illustrated, constructed of aluminum.
With reference also to
Each brace 632 has at least two brace screw bosses 634 at each of the upper and lower brace ends 632a, 632b. The upper beam 622a and the lower beam 622b have apertures 640a, 640b therethrough in registration with the brace screw bosses 634. A plurality of brace fasteners 636 are provided for securing the braces 632 to the beams 622a, 622b, each fastener 636 extending through one of the apertures 640a, 640b and into a respective one of the brace screw bosses 634 in registration therewith.
Each brace 632 has transversely spaced apart contact surfaces 676 that engage opposed inner surfaces 678 of the casing 630, wherein lateral movement of the casing 630 relative to the brace 632 is inhibited.
With reference also to
The upper beam 622a comprises an extruded beam lineal including laterally spaced-apart attachment grooves 701 (
The railing system 610 can further include a mounting bracket 707 (
In the example illustrated, and with reference to attachment of the upper rail 612a, one mounting bracket 707 is provided at each end of the upper rail. Each mounting bracket includes a generally planar first flange 711 oriented parallel to the upper rail 612a and secured to the upper beam 622a, and a generally planar second flange 713 joined to the first flange and oriented vertically for securing the mounting bracket 707 to the upright 618.
The extruded beam lineal can include integrally extruded bracket engagement members for engaging the first flange 711 of the mounting bracket 707 in sliding fit. In the example illustrated, bracket engagement members are provided, including a transverse support surface 717 (
A bracket fastener 725 can be passed through an aperture in the first flange 711 and anchored in the transverse support surface 717 for fixing the first flange 711 to the upper rail 612a. The transverse support surface 717 can be provided with an integrally extruded central score line 727 (
In the example illustrated, the bracket engagement members further comprise a pair of top retaining segments 731 extending horizontally inwardly from opposed sides of the upper beam 622a (
The bracket engagement members can further include a pair of sideways retaining segments 735 each extending generally downwardly from respective ones of the top retaining segments 731. Each sideways retaining segment 735 can have a side engagement surface 737 spaced vertically intermediate the bottom surfaces 733 of the top retaining segments 731 and the transverse support surface 717. The side engagement surfaces 737 are, in the example illustrated, configured to engage opposed lateral edges 739 of the first flange 711, and to receive the lateral extent of the first flange 711 between the laterally opposed side engagement surfaces 737 in sliding fit.
