Abstract
Abstract A structure, useful as a balustrade or fence, comprising a rail attached to a plurality of pickets. The rail has first and second longitudinal members that are pressed together to form the rail. There are spaced openings formed in one longitudinal member with an open edge for each opening at an edge of the longitudinal member. Channels are formed in each side of the picket member, adjacent an end of the picket member. There are projections on the first and second members, adjacent to each opening. Each projection is received in a channel of a picket. The arrangement of channels and projections provides a rattle-free structure. The structure can be further improved by the incorporation of a settable compound to assist in the pressing together of the first and second members.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
266 words
A rail structure having a rail attached to a plurality of pickets, the rail comprising first and second longitudinal members that are pressed together to form the rail; a plurality of spaced openings formed in the first longitudinal member with an open edge for each opening at an edge of the first longitudinal member; an opposed pair of spaced channels formed in each side of each picket adjacent and end of the picket, a first channel of each pair being closer to the end of the picket than the second channel of each pair; first projections in the interior of each first and second longitudinal member to fit closely into the opposed first channels on a picket; second projections on each first and second longitudinal member to fit closely into opposed second channels on a picket; a pair of male members formed at a pair of side edges of the first longitudinal member; a pair of female members formed at a pair of side edges of the second longitudinal member to receive the male members of the first longitudinal member with a press fit to form the rail; whereby pressing together of the first and second longitudinal members, with pickets located between the first and second longitudinal members in the plurality of spaced openings formed in the first longitudinal member, to engage the male members of the first longitudinal member with a female members of the second longitudinal member engages the first and second projections respectively in the first and second channels with a press fit that prevents movement of the pickets relative to the rail.
Claim 2
Dependent Claim
266 words
A rail structure having a rail attached to a plurality of pickets, the rail comprising first and second longitudinal members that are pressed together to form the rail; a plurality of spaced openings formed in the first longitudinal member with an open edge for each opening at an edge of the first longitudinal member; an opposed pair of spaced channels formed in each side of each picket adjacent and end of the picket, a first channel of each pair being closer to the end of the picket than the second channel of each pair; first projections in the interior of each first and second longitudinal member to fit closely into the opposed first channels on a picket; second projections on each first and second longitudinal member to fit closely into opposed second channels on a picket; a pair of male members formed at a pair of side edges of the first longitudinal member; a pair of female members formed at a pair of side edges of the second longitudinal member to receive the male members of the first longitudinal member with a press fit to form the rail; whereby pressing together of the first and second longitudinal members, with pickets located between the first and second longitudinal members in the plurality of spaced openings formed in the first longitudinal member, to engage the male members of the first longitudinal member with a female members of the second longitudinal member engages the first and second projections respectively in the first and second channels with a press fit that prevents movement of the pickets relative to the rail.
Claim 3
Dependent Claim
25 words
