Abstract
A deck and stair railing has top and bottom rails joined to upright posts and upright tubes extended between the rails. Ball knobs mounted on plates or the rails are secured with deck screws to the rails to retain the tubes in assembled relation with the rails. The ball knobs have circumferential ribs located in force fit relation with inside surfaces of the tubes. The tubes have projections that engage the ball connectors to prevent the tubes from rotating relative to the ball connectors.
Claims17
A railing comprising:
- laterally spaced upright posts,
- a top rail extended between said posts,
- first means connecting the top rail to said posts,
- a bottom rail located below the top rail and extended between said posts,
- second means connecting the bottom rail to said posts,
- a plurality of laterally spaced upright spindles extend between said top and bottom rails,
- first ball knobs,
- first fasteners attaching the first ball knobs to the top rail,
- second ball knobs,
- second fasteners attaching the second ball knobs to the bottom rail in general vertical alignment with the first ball knobs,
- said spindles having opposite first and second ends with inside walls located in telescopic relation with the first and second ball knobs thereby anchoring the spindles on the rails,
- a first spacer located between the first ball knobs and the top rail,
- said first spacer comprising a flat first plate extended along the length of the top rail between said posts and located in engagement with the top rail,
- the first end of each spindle being located in engagement with said first plate,
- said first fasteners retaining the first plate in engagement with the top rail and connecting the first ball knobs to the top rail, and
- a second spacer located between the second ball knobs and the bottom rail,
- said second spacer comprising a flat second plate extended along the length of the bottom rail between said posts and located in engagement with the bottom rail,
- the second end of each spindle being located in engagement with said second plate,
- said second fasteners retaining the second plate in engagement with the bottom rail and connecting the second ball knobs to the bottom rail,
- said first and second plates having laterally spaced and centered holes for the first and second fasteners thereby laterally spacing the adjacent first ball knobs and the adjacent second ball knobs and the adjacent spindles.
