Abstract
A ladder platform and safety rail device is provided for mounting on one or more ladders and includes a U-shaped bracket with an insert leg for extending through a hollow ladder rung. The bracket also includes a rail leg, which is releasably connected to a rail. The bracket legs extend through a bracket leg plate, which secures their ends together with the device mounted on one or more ladders. A working deck is formed by a plank supported on a ladder jack attached to each ladder. A rail support strut extends between the rail and the plank.
Claims15
A platform support and safety rail device for connection to a ladder, which device comprises:
- a rail assembly including a bracket with a first leg adapted for connection to the ladder and a second leg connected to and located in spaced relation from said first leg;
- said rail assembly further including a rail with an end connected to the bracket second leg;
- and
- a platform assembly comprising a platform having a working deck and being located below said rail with said ladder in a generally upright position;
- said platform assembly further including a ladder jack connected to said platform and said ladder and supporting said platform on said ladder.
A ladder platform and safety rail device for a pair of ladders each including a pair of ladder side members and multiple, hollow, tubular ladder rungs extending between and open at said side members, which device includes:
- a rail assembly including a pair of brackets each having an insert leg adapted for placement generally within a rung of said ladder and a rail leg connected to and located in spaced relation from said insert leg;
- said rail assembly further including a rail with opposite ends each connected to a respective bracket rail leg;
- said rail assembly further including a pair of bracket leg plates each including a pair of receivers each receiving a respective bracket leg with said brackets mounted on said ladders;
- a platform assembly comprising a platform having a working deck and being located below said rail with said ladders in generally upright positions;
- said platform assembly further including a pair of ladder jacks each connected to a respective ladder and supporting said platform thereon;
- and
- a strut with an upper end connected to said rail and a lower end connected to said platform.
A ladder platform and safety rail device for a pair of ladders each including a pair of ladder side members and multiple, hollow, tubular ladder rungs extending between and open at said side members, which device includes:
- a rail assembly including a pair of U-shaped brackets each having an insert leg adapted for placement generally within a rung of said ladder and a rail leg connected to and located in spaced relation from said insert leg;
- each said bracket including an approximately 180° curved return connected to and extending between said bracket legs;
- said rail assembly further including a rail with opposite ends each connected to a respective bracket rail leg;
- said rail assembly further including a pair of bracket leg plates, each bracket leg plate including a pair of receivers and each receiver receiving a respective bracket leg with said brackets mounted on said ladders;
- each said rail end being adapted for telescopic interconnection with a respective bracket rail leg end;
- multiple retaining pins each removably receivable in a respective telescopic interconnection;
- a platform assembly comprising a plank with a working deck and being located below said rail with said ladders in generally upright positions;
- said platform assembly further including a pair of ladder jacks each connected to a respective ladder and supporting said plank thereon;
- a generally tubular strut with a flattened upper end connected to said rail and a flattened lower end connected to said plank;
- said strut upper end forming a hook configured for placement over said rail;
- an upper strut mechanical fastener extending through said strut upper end and said rail;
- said strut lower end forming a foot configured for placement on said platform;
- and
- a lower strut mechanical faster extending through said strut lower end and into said plank.
