Abstract

A stairway system. The stairway system includes a plurality of spaced apart treads, a handrail and a baluster assembly. The baluster assembly includes at least one baluster per tread. The baluster includes at least one rake anchor adapted to abut the angled support surface of the handrail adjacent to one end of the baluster, a rake shoe adapted for concealing the interface between the rake anchor and the angled support surface of the handrail and an anchor assembly including an anchor adapted for receiving the other end of the baluster. The stairway system further includes a handrail support for supporting the handrail.

Claims (15)

1. A kit for a baluster assembly for a stairway system having a plurality of spaced apart treads, at least one one-piece baluster per tread and a handrail, said kit comprising:

(a) a rake anchor attached to said one-piece baluster and adapted to abut an angled support surface of said handrail adjacent to one end of said baluster; said rake anchor including:

(i) a generally inverted cup-shape adapter inserted into a hole in the bottom of said handrail, said adapter receiving one end of said one-piece baluster, wherein said one end of said one-piece baluster extends through said rake anchor and into said adapter, whereby said one end of said one-piece baluster is directly secured by said adapter in the hole in the bottom of said handrail without an additional fastener;

(ii) a rake shoe adapted for concealing the interface between said rake anchor and the angled support surface of said handrail, said rake shoe fastened to said rake anchor such that said rake shoe pivots about the rake anchor to match with the angled pitch of said support surface of said handrail; and

(b) an anchor assembly including an anchor having at least one open side face adapted to be attached to the top surface of a tread for receiving the other end of said one-piece baluster.

2. The baluster assembly according to claim 1 , wherein said anchor is adapted to receive the other end of said baluster on its installation face.

3. The baluster assembly according to claim 2 , wherein said anchor is generally U-shaped.

4. The baluster assembly according to claim 3 , wherein said anchor is an open boxed shaped cross-section.

5. The baluster assembly according to claim 1 , wherein said anchor further includes a base and a fastener for attaching said base to the top surface of a tread.

6. The baluster assembly according to claim 5 , wherein said base is convex-shaped to be received by a pre-existing plughole in said tread thereby self-aligning within said pre-existing plughole.

7. The baluster assembly according to claim 5 , wherein said anchor assembly further includes a shoe adapted for concealing the interface between said anchor and said other end of said baluster attached to said tread.

8. The baluster assembly according to claim 1 , wherein the upper surface of said rake anchor forming the interface between said rake anchor and the angled support surface of said handrail is French curve-shaped for pivoting with respect to the angled support surface of said handrail.

9. The baluster assembly according to claim 1 , wherein said anchor further includes an angled base and a fastener for attaching said angled base to the top surface of a kneewall.

10. The baluster assembly according to claim 9 , wherein said angled base further includes at least one relief to allow said angled base to bend to conform to the angle of the top surface of said kneewall.

11. The baluster assembly according to claim 9 , wherein said anchor assembly further includes (i) at least one rake anchor adapted to abut said kneewall adjacent to said other end of said baluster and (ii) a rake shoe adapted for concealing the interface between said rake anchor and said other end of said baluster attached to said kneewall.
