Railing assembly with detachable and upgradeable components
A railing system includes an upper core member having a cap connector. In a first embodiment, a railing system includes a cap member having a cap flange that detachably couples with the cap connector on the upper core member. The cap member forms an enclosed conduit between the cap member and the upper core member. In a second embodiment, a kit for fabricating a railing span is contained in a packaging. The kit includes an upper core member and lower core member having selected lengths and a plurality of balusters for connection between the upper and lower core members. In a third aspect of the invention, a method of routing an opening for a baluster used in an inclined railing structure includes the step of plunging a router bit into a side of a component at an angle based on the installed angle of the inclined railing structure.
1. A railing system comprising:
an elongated upper rail;
an elongated lower rail; and
a plurality of balusters extending between the upper rail and the lower rail;
the upper rail comprising:
an elongated upper core member comprising an upper portion and a lower portion, the upper portion comprising an upper flange having opposing longitudinal edges each comprising a cap connector, and the lower portion comprising a lower flange having opposing longitudinal edges each comprising a base connector, and a pair of opposing sidewalls extending from the lower flange and forming an elongated inverted channel in the core member;
a cap member comprising an elongated central body having a pair of opposing sidewalls defining a channel receiving the upper portion of the core member, each sidewall of the cap member having a cap flange adjacent the central body of the cap member and in interlocking engagement with a respective one of the cap connectors of the core member such that the central body of the cap member engages the longitudinal edges of the upper flange;
wherein an upper surface of the upper flange of the core member and an inner surface of the central body of the cap member face each other and diverge away from one another to form at least one conduit adapted to carry one or more utility lines inside the railing system; and
a base member comprising an elongated central body having a pair of opposing sidewalls defining a channel receiving the lower portion of the core member, each sidewall of the base member having a base flange in interlocking engagement with a respective one of the base connectors of the core member, the central body of the base member comprising a plurality of openings aligned with the inverted channel of the core member;
wherein the plurality of balusters extend through the plurality of openings in the base member and into the inverted channel in the core member to connect the plurality of balusters with the upper rail; and
wherein the sidewalls of the cap member and the sidewalls of the base member engage one another in an overlapping relationship such that the cap member and the base member substantially enclose and conceal the core member.
2. The railing system of claim 1 comprising a utility line extending through said conduit between said core member and said cap member, wherein said utility line is concealed beneath said cap member.
3. The railing system of claim 2 , wherein the utility line comprises a line associated with a light fixture, an audio component, a video component, a computer, a telephone, a plumbing fixture, a grill, or a device powered by compressed air.
4. The railing system of claim 1 , wherein each of said plurality of balusters comprises an upper end and a lower end, said upper end engaging with the base member.
5. The railing system of claim 4 , wherein the plurality of openings in the base member comprise routed openings.
6. The railing system of claim 5 , wherein the base member extends along a longitudinal axis, and the routed openings extend through the base member at an acute angle with respect to the longitudinal axis of the base member.
7. The railing system of claim 6 , wherein the angle is between about 29 and about 41 degrees.
8. The railing system of claim 1 comprising a lower core member extending generally parallel with said upper core member, said lower core member comprising a channel facing the lower portion of the upper core member.
9. The railing system of claim 8 , the lower rail comprising a cover extending over the lower core member, said cover comprising a routed opening generally aligned with the channel in the lower core member, said channel adapted to receive a lower end of one of said plurality of balusters, said lower end extending through the routed opening in the cover and engaging with the lower core member.
10. The railing system of claim 9 , comprising a surface treatment on at least one of said cap member, base member and cover.
11. The railing system of claim 10 , wherein the surface treatment comprises a metallic jacket.
12. The railing system of claim 9 , wherein said railing system has a load bearing capacity operable to resist deflection of the railing, said upper and lower core members being mounted to a support structure to provide said load bearing capacity, said cap member, base member and cover member comprising decorative components that are detachable from said core members without reducing the load bearing capacity of the railing system.
13. The railing system of claim 1 , comprising a bracket and mounting hardware connected with said upper core member, said bracket and mounting hardware being disposed within and completely concealed by said cap member and said base member.
14. The railing system of claim 13 , wherein the bracket comprises one or more inwardly facing ribs configured for connection with the upper core member in a press fit.
15. The railing system of claim 14 , wherein the bracket comprises a socket for receiving an end of the upper core member, the socket forming a clearance gap between the bracket and the end of the upper core member to accommodate expansion of the upper core member.
16. The railing system of claim 1 , wherein one of the upper core member and the cap member is concavely shaped at a location adjacent the other of the upper core member and the cap member to form said at least one conduit.
17. The railing system of claim 1 , wherein the upper core member and the cap member each comprise concave shapes forming opposing sides of said conduit.
