[0025] A railing system 110 in accordance with an example of one aspect of the Applicants teaching can be seen In Figure 1. The railing system 110 comprises an upper rail 112, a lower rail 114, and a plurality of balusters each extending generally vertically between the upper and lower rails 112, 114.
In the example illustrated, the railing system is shown in a horizontal configuration, with horizontal upper and lower rails 112, 114. The railing system I '1'

-6-110 can also be configured for inclined applications, such as along a staircase, with inclined rails 112, 114 and vertical balusters 116.
[0026] Each of the upper and lower rails 112, 114 are 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 119.
[0027] Referring now to Figures 2 and 3, the upper rail 112 comprises a proximal member 122, a reinforcement member 124, and a cover member 126, each extending generally along the length of the upper rail 112. The proximal member 122 is securable to the upper ends of the balusters 116.
[0028] In the example illustrated, the cover member 126 is disposed in generally facing relation to the proximal member 122, and the reinforcing member 124 is disposed between the proximal and cover members 122, 126. A
first and a second connection means can be provided to secure together the members 122, 124, and 126. The first connection means can couple together the reinforcing member 124 with a first one of the proximal or cover members 122, 126. The second connection means can couple together the other (second) one of proximal or cover members 122, 126 with either the first one of the proximal or cover members or with the reinforcement member 124 or with both the reinforcement member 124 and the first one of the proximal or cover members 122, 126.
[0029] In the example illustrated, the first connection means is adapted to couple together the reinforcing member 124 with the proximal member 122, and the second connection means is adapted to couple together the cover member 126 with the reinforcement member 124.
[0030] As best seen in Figure 3, the reinforcement member 124 is, in the example illustrated, provided with first attachment elements 130 for securing together the reinforcement member 124 and the proximal member '122. The

- 7 -reinforcement member 124 can have second attachment elements 132 for securing together the reinforcement member 124 and the cover member 126.
Either one or both of the first and second attachment elements 130, 132 can be Unitary With the reinforcement member 124.
[0031] In the example illustrated, the reinforcement member 124 comprises a pair of sidewalls 134 that are disposed generally in a vertical orientation, between the proximal member 122 and the cover member 126, when viewing the rail 112 in cross-section (Fig. 3). Each sidewall 134 has a proximal edge 136 adjacent the proximal member 122, and a distal edge 138 adjacent the cover member 126. A transverse web 140 can join together the opposed sidewalls. The transverse web 140 can extend generally between the sidewalls 134, adjacent the proximal edges 136 of the sidewalls 134.
[0032] In the example illustrated, the first attachment element 130 comprises a pair of first lugs 142, each of the first lugs 142 projecting laterally outwardly from a respective sidewall 134, and adjacent the proximal edge 136 thereof. In the example illustrated, the second attachment element 132 comprises a pair of second lugs 144, each Of the second lugs 144 projecting laterally outwardly from a respective sidewall 134, and adjacent the distal edge 138 thereof. The reinforcement member 124 can be constructed of a strong, tough material. In the example illustrated, the reinforcement member 124 is a roll-formed profile of about 14-gauge structural steel, and can be galvanized_ [0033] With reference to Figures 3 and 4, the proximal member 122 can comprise a base 150 having an outer surface 152 directed towards the ends of the balusters 116 of the assembled railing system 110, and an inner surface directed towards the reinforoement member 124. At mounting locations where the balusters 116 meet the rail 112, at least a portion of the outer surface 152 of the base 122 can bear against the end face 155 (Fig. 4) of the respective balusters 116. The proximal member 122 can be secured to the balusters 116 by passing fasteners 156 through the base 150 and into the balusters 116. In the I "7

- 8 -example illustrated, the fasteners 156 comprise screws having threaded shanks 158 engaged within screw bosses 160 provided in the balusters 116, and heads 162 that bear against the inner surface 154 of the base 150. The base 150 can be provided with apertures 164 for registration with the screw bosses 160 to receive the shanks 158 therethrough. The upper surface 154 of the base 150 can be provided with depressions 168 for receiving the heads 162 of the fasteners 156 In a countersunk manner_ [0034] Referring again to Figure 3, the proximal member 122 can further comprise a first coupling element 172 for inter-engaging with the first attachment element 130 of the reinforcernent member 124. In the example illustrated, the first coupling element 172 comprises a pair of first arms 174, the first arms spaced laterally apart from each other to receive the first lugs 142 between the first arms 174. Each of the first arms 174 is, in the example Illustrated, directed generally vertically towards the reinforcement member 124, and comprises a laterally inwardly directed barb 176. Each barb 176 has an underside surface 178 spaced vertically apart from the inner surface 154 of the base 150, and configured to bear against a distal surface 180 of a respective one of the first lugs 142. The opposing underside surface 178 of the barb and inner surface 154 of the base 150, and an inner surface 182 of the arm 174 disposed therebetween and laterally offset therefrom defines a recess 184 for receiving a respective one of the lugs 142 in the assembled rail 112.
[0035] The proximal member 122 can be constructed of plastic, and, in the example illustrated, comprises an extruded vinyl lineal. The base 150 and first arms 174 are, in the example illustrated, integral with each other_ The proximal member 122 can be cut to length after extrusion, The optional holes 164 can be provided using, for example, a jig and drill press to facilitate locating the balusters 116 at a desired position and spacing along the length of the proximal member .122 when securing the balusters 110 to the proximal member 122.

- 9 -[0036] Referring again to Figures 3 and 4, the cover member 126 is, in the example illustrated, secured over the reinforcing member 124, in a vertically inverted orientation relative to the proximal member 122. The cover member 126 can be similar in structure to the proximal Member 122. Like features of the cover member 126 (compared to the proximal member 122) are identified by like reference characters, incremented by 50.
[0037] In the example illustrated, the cover member 126 comprises a base 200 having an outer surface 202 directed away from the reinforcement member 124, and an inner surface 204 directed towards the reinforcement member 124.
The outer surface 202 can have a convex shape (when viewed in cross-section) to provide a comfortable surface when the upper rail 112 is grasped by the hand of a user.
[0038] The cover member 126 can further comprise a second coupling element 222 for inter-engaging with the second attachment element 132 of the reinforcement member 124. In the example illustrated, the second coupling element 222 comprises a pair of second arms 224, the second arms 224 spaced laterally apart from each other to receive the second lugs 144 of the second attachment element 132 of the reinforcement member 124 between the second arms 224.
[0039] Each of the second arms 224 is, in the example illustrated, directed generally vertically towards the reinforcement member 124, and comprises a laterally inwardly directed second barb 226. Each second barb 226 has an underside surface 228 spaced vertically apart from the inner surface 204 of the base 200, and configured to bear against a distal surface 230 of a respective one of the second lugs 144. The opposing underside surfaee 228 of the second barb 226 and inner surface 204 of the second base 200, and an inner surface 232 of the arm 224 disposed therebetween and laterally offset therefrom defines a second recess 234 for receiving a respective one of the second lugs 144 in the assembled upper rail 112.

- 10 -[00401 Further details of the lower rail 114 will now be described, with reference to Figures 5 and 6. The lower rail 114 can be of similar structure to that of the upper rail 112. In the example illustrated, like features of the lower rail 114 (Compared to the upper rail 112) are identified by like reference characters, incremented by 200.
[0041] The lower rail 114 comprises a proximal member 322, a reinforcement member 324, and a cover member 326, each extending generally along the length of the lower rail 114. In the example illustrated, the cover member 326 is disposed in generally facing relation to the proximal member 322, and the reinforcing member 324 is disposed between the proximal and cover members 322, 326. As for the upper rail 114, the members 322, 324, and 326 of the lower rail can be secured together by a first and a second connection means.
The first connection means can couple together the reinforcing member 324 with a first one of the proximal or cover members 322, 326, The second connection means can couple together the other (second) one of proximal or cover members 322, 326 with either the first one of the proximal or cover members 322, 326 or with the reinforcement member 324 or with both.
[0042] In the example illustrated, the first connection means associated with the lower rail 114 is adapted to couple together the reinforcement member 324 with the proximal member 322, and the second connection means associated with the lower rail 114 is adapted to couple together the cover member 326 with the reinforcement member 324.
[0043] In the example illustrated, the reinforcement member 324 of the lower rail 114 is of identical construction to the reinforcement member 124 of the upper rail 112, and mounted to the lower rail 114 in a vertically inverted orientation relative to the reinforcement member 124 of the upper rail 112.
The reinforcement member 324 thus includes first attachment elements 330 comprising a pair of first lugs 342, and second attachment elements 332 I

- 11 -comprising a pair of second lugs 344, each corresponding identically to the features 130, 142 and 132, 144 of the upper rail 112.
[0044] The proximal member 322 of the lower rail 114 can have similar structure as the proximal member 122 of the upper rail 112. In the example illustrated, the proximal member 322 of the lower rail 114 and the proximal member 122 of the upper rail 112 are of identical profile in cross-section, and can be cut from lineals extruded through the same die. The proximal member 322 of the lower rail 114 in the example illustrated accordingly comprises a base 350 having outer and inner surfaces 352, 354, each of which correspond identically to the base 150 and outer and inner surfaces 152, 154 thereof. The proximal member 322 is, in the illustrated example of a railing system 110, mounted in a vertically inverted orientation relative to the proximal member 112, with the outer surface 352 of the proximal member 322 bearing against the lower ends of the balusters 116 at mounting locations where the balusters 116 meet the lower rail 114.
[0045) Referring again to Figures 5 and 6, the cover member 320 is, in the example illustrated, secured over the reinforcing member 324, in a vertically inverted orientation relative to the proximal member 322. The cover member 326 can be similar in structure to the cover member 126 of the upper rail, and can be, but need not be, identical to the cover member 126. In the example illustrated, the cover member 326 of the lower rail 114 comprises generally the same features as the cover member 126 of the upper rail, with some distinctions as set out below. Like reference characters of the cover member 326 in comparison to the cover member 126 are identified by like reference characters, incremented by 200.
(0046) In the example illustrated, the cover member 326 comprises a base 400 having an outer surface 402 directed away from the reinforcement member 324, and an inner surface 404 directed towards the reinforcement member 324.

- 12 -The outer surface 402 is, in the example illustrated, of a flatter profile than the corresponding outer surface 202 of the cover member 126 of the upper rail 112.
[0047] The cover member 326 further comprises a second coupling element 422 in the form of a pair of second arms 424 for inter-engaging with the second attachment element 332 of the reinforcement member 324. Each of the second arms 424, in the example illustrated, comprises a laterally inwardly directed second barb 426, each having an underside surface 428 spaced vertically apart from the inner surface 404 of the base 400, and configured to bear against a distal surface 430 of a respective one of the second lugs 344.
The opposing underside surface 428 of the second barb 426 and inner surface 404 of the second base 400, and an inner surface 432 of the arm 424 disposed therebetween and laterally offset therefrom defines a second recess 434 for receiving a respective one of the second lugs 344 in the assembled lower rail 314.
[0048] To assemble the railing system 110, the opposing proximal members 122 and 322 of the respective upper and lower rails 112, 114 can be secured to the respective upper and lower ands of the balusters 116. In the example illustrated, this can be accomplished by positioning the ends of the balusters at the desired mounting locations along the proximal members 122, 322 (aligning the screw bosses 160 with the optional apertures 164, 364, if provided). The screws 156 can then be inserted through the respective bases 150, 350, and into the balusters 116, with the heads 162 of the screws 156 bearing against the inner surfaces 154, 354 of the respective bases 150, 360.
[0049] The reinforcing members 124, 324 can then, in the example illustrated, be coupled to the respective proximal members 122, 322, by aligning the reinforcing members with the proximal members end-to-end with the first lugs 130, 330 in registration with the respective first recesses 184, 384, and sliding the members 124, 324 into the members 122, 322 in telescoping fashion.
Alternatively, the reinforcing members 124, 324 can be coupled with the I """

- 13 -respective proximal members 122, 322 by snap fit, aligning the members 122 and 124 in facing relation, and the members 322 and 324 in facing relation, with the respective first lugs 130, 330 adjacent the distal ends of the respective first arms 174, 374, and then pressing the lugs 130, 330 past the barbs 176, 376 and into the corresponding recesses 184, 384.
[0050] Next, in the illustrated embodiment, the reinforcing members 124, 324 can be secured to the uprights 118. The railing system 110 can include brackets 460 (Figs. 4 and 6) provided at either end of each of the upper and lower rails 112, 114 to facilitate securing the reinforcing members 124, 324 to the uprights 118. Each bracket 460 can include a first flange 462 and a second flange 464. The first flange 462 can be adapted to slide into a groove or keyway 466 formed by hollow interiors 468 of the opposing lugs 142, 342 (Figs. 3 and 5).
When inserted into the keyways 466, the brackets 460 are constrained from moving relative to the reinforcement members 124, 324 in any direction other than along the length of the members.
[0051] The second flange 464 is adapted to be secured to the uprights 118. Referring to Figure 7, the uprights 118 can comprise newel posts 119 having an extruded vinyl tube or sleeve 470 installed over a central core 472 of steel or wood. The second flange 464 can include an aperture 474 therethrough, and can be secured to the newel post 119 by a fastener 476 extending through the aperture 474 in the second flange 464, through the sleeve 470 and into the core 472. The sleeve 470 can have integrally formed score lines 478 along one or more faces to indicate proper lateral positioning of the bracket 460 (and hence fastener 476) relative to the upright 118.
[0052] After the reinforcement members 124, 324 have been mounted to the uprights 118, the cover members 126, 326 can be installed over the reinforcement members 124, 324 of the respective upper and lower rails 112, 114. The cover members 126, 326 can be assembled by aligning each cover member 126, 326 between the uprights 118, with the Second arms 224, 424 in

- 14 -vertical registration with the second lugs 144, 344 of the respective reinforcement member 124, 324. The cover member 126, 326 can then be pressed towards the reinforcement member 124, 324, urging apart the second arms 224, 424 and the lugs 144. 344 past the barbs 226, 426 and into the recesses 234, 434.
[0053] In the example illustrated, the first and second arms of the proximal and cover members of each rail are long enough (in a vertical direction) to generally abut or overlap, thereby generally concealing the reinforcement member 124, 324. The first arms are shorter than the second arms, in the example illustrated, and the first arms can be of single-walled construction to facilitate bending or pivoting of the first arms about the point of connection between the first arms and the base when urging the first lugs past the first barbs 176, 376.
[0054] In some examples, the members 322, 324, and 326 of the lower rail 114 can each be different than the corresponding members 122, 124, and 126 of the upper rail. In some examples, the members 322, 324, 326 of the lower rail 114 can each be identical to the corresponding members 122, 124, 126 of the upper rail 112. In some examples, the proximal members 122, 322 of the upper and lower rails 112, 114 can be identical to the cover members 126, 326 of the upper and lower rails, respectively.
[0055] Referring now to Figures 8 and 9, an alternative example of a rail is illustrated. The rail of Figures 8 and 9 is identified at reference character 512, and for clarity is described for use as an upper rail 512, although use of the rail 512 or elements thereof as a lower rail is also comprehended by the applicant's teaching. The upper rail 512 is similar to the upper rail 112, and like features are identified by like reference characters, incremented by 400.
[0056] The upper rail 512 comprises a proximal member 522, a reinforcement member 524, and a cover member 526, each extending generally along the length of the upper rail 512. First and second connection means are

- 15 -provided for coupling together the members 622, 524, and 526. in the example illustrated, the first connection means is adapted to couple together the reinforcing member 524 with the proximal member 522, and the second connection means is adapted to couple together the cover member 526 with the proximal member 522.
[0057] The first connection means associated with the upper rail 512 is similar to that of the upper rail 112. The reinforcement member 524 is, in the example illustrated, provided with first attachment elements 530 for securing together the reinforcement member 524 and the proximal member 622. The first attachment elements 530 can comprise a pair of first lugs 542, each of the first lugs 542 projecting laterally outwardly from a respective sidewall 534 of the reinforcement member 524, and adjacent the proximal edge 536 thereof.
[0058] The proximal member 522 can comprise a first coupling element 572 for inter-engaging with the first attachment element 530 of the reinforcement member 524. In the example illustrated, the first coupling element 572 comprises a pair of first arms 574, the first arms 574 spaced laterally apart from each other to receive the first lugs 542 between the first arms 574. Each of the first arms 574 is, in the example illustrated, directed generally vertically towards the reinforcement member 524, and comprises a laterally inwardly directed barb 576. The opposing underside surface 578 of each barb 576 and inner surface 554 of the base 550, and an inner surface 582 of the arm 574 disposed therebetween and laterally offset therefrom define a recess 584 for receiving a respective one of the lugs 542 in the assembled rail 512.
[0059] In the example illustrated, the second connection means associated with the upper rail 512 is different in some respects than that of the upper rail 122. Rather than providing second attachment elements on the reinforcement member, the proximal member 522 comprises the second attachment elements 532, the second attachment elements adapted to secure together the proximal member 522 and the cover member 526. In the example

- 16 -illustrated, the second attachment element 532 comprises a pair of catches 544, each of the catches 544 projecting laterally inwardly from a respective one of the first arms 574, and adjacent a distal edge thereof.
