Abstract
Abstract Balusters and rails are angularly adjustable after their assembly to fit the different pitches of stairways. To this end a rail is characterized by: (a) the rail having an elongated recess sunk in one lateral side thereof, and having at least one interior socket laterally intersecting said recess, (b) the socket configured to pivotally receive the baluster pivot with the baluster projecting from the rail, the socket having an interior laterally facing wall defined by the rail, (c) the recess configured to receive a moulding attached to the rail to laterally confine the pivot in the socket between the moulding and said interior wall, for pivoting in said so

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
For use in a connection between a one-piece rail and at least one baluster having a pivot at an end thereof, the improvement comprising (a) the rail having an elongated recess sunk in one exterior lateral side thereof, and having at least one interior socket laterally intersecting said recess, (b) the socket having a curved wall that pivotally receives the baluster pivot with the baluster projecting from the rail, the socket having an interior laterally facing wall defined by the rail, said curved wall and said laterally facing wall being of one-piece with the rail, (c) the recess having L-shaped interior sides that receive and confine an exterior moulding fitting to the rail which laterally confines the pivot in the socket between the moulding and said interior wall, that providing pivoting in said socket, said L-shaped interior sides being laterally exposed to the exterior.
Claim 2
Dependent Claim
144 words
For use in a connection between a one-piece rail and at least one baluster having a pivot at an end thereof, the improvement comprising (a) the rail having an elongated recess sunk in one exterior lateral side thereof, and having at least one interior socket laterally intersecting said recess, (b) the socket having a curved wall that pivotally receives the baluster pivot with the baluster projecting from the rail, the socket having an interior laterally facing wall defined by the rail, said curved wall and said laterally facing wall being of one-piece with the rail, (c) the recess having L-shaped interior sides that receive and confine an exterior moulding fitting to the rail which laterally confines the pivot in the socket between the moulding and said interior wall, that providing pivoting in said socket, said L-shaped interior sides being laterally exposed to the exterior.
Claim 3
Dependent Claim
24 words
The improvement of claim 1 wherein said socket is generally cylindrical and defines a lateral axis generally normal to a plane bisecting the rail.
Claim 4
Dependent Claim
23 words
The improvement of claim 1 wherein said rail has an elongated notch formed therein adjacent a corner formed by said L-shaped interior sides.
Claim 5
Dependent Claim
29 words
The combination that includes the rail of claim 1 and said moulding received in said recess and attached to the rail for laterally confining the pivot in the socket.
Claim 6
Dependent Claim
34 words
The combination that includes the rail of claim 3 and said moulding received in said recess and attached to said L-shaped interior sides of the rail thereby laterally confining the pivot in the socket.
Claim 7
Dependent Claim
32 words
The combination of any one of claims 4 or 5 wherein the moulding has a laterally facing outer side configured to match a corresponding laterally oppositely facing side portion of the rail.
Claim 8
Dependent Claim
29 words
The combination of any one of claims 4 or 5 including sad baluster with said pivot confined in said socket to pivot therein, the pivot having a spherical surface.
Claim 9
Dependent Claim
125 words
The combination of claim 6 including said baluster with said pivot in said socket, and wherein the baluster has another pivot at the opposite end thereof and there being a second rail, and including (d) the second rail having an elongated recess sunk in one lateral side thereof, and having at least one interior socket laterally intersecting said recess, (e) the socket in the second rail configured to pivotally receive the baluster other pivot with the baluster projecting from the rail, the socket having an interior laterally facing wall defined by the rail, (f) and a second moulding received in said recess in the second rail and attached to the second rail to pivotally confine said other pivot in the socket in the second rail.
