Claims
- 1. A ladder system for positioning a ladder between two spaced storage areas which are positioned on a floor, a longitudinal direction being defined as extending parallel to the spaced storage areas, a lateral direction being defined as extending between said spaced storage areas, the ladder system comprising:
- a ladder adapted to contact the floor;
- a track system adapted to be attached to at least one storage area, said ladder being mounted on said track system for selective movement along said longitudinal direction only, along said lateral direction only, and along both said longitudinal direction and said lateral direction simultaneously, said track system including a first guide track and a second guide track, said guide tracks each extending along a longitudinal axis, said track system further including a first rod extending along a lateral axis between said guide tracks, said first rod being coupled to said first and second guide tracks for longitudinal movement along said guide tracks;
- a pair of spaced rollers attached to said ladder for coupling said ladder to said first rod, said rollers being spaced apart at a distance that is generally the diameter of said first rod, said first rod being interposed between said pair of rollers, said rollers cooperatively gripping said first rod and guiding said ladder for lateral and pivoting movement relative to said first rod, said ladder being movable laterally between said first and second guide tracks, and said ladder being adapted to pivot about said lateral axis of said first rod; a pair of laterally spaced sidewalls, one of said guide tracks being associated with one of said sidewalls, said first rod being rigidly secured to said sidewalls and extending between said sidewalls; and
- a second rod rigidly secured to said sidewalls and extending between said sidewalls for providing increased stability.
- 2. A ladder system as recited in claim 1, wherein a second pair of said rollers are spaced along said first rod in said lateral direction for guiding said ladder.
- 3. A ladder system as recited in claim 1, wherein said pair of rollers have curved surfaces received on said first rod corresponding to the outer periphery of a cross section of said first rod such that said rollers may pivot about said first rod.
- 4. A ladder system for use with a pair of laterally spaced storage areas, a longitudinal direction being defined as extending parallel to the spaced storage areas and a lateral direction being defined as extending between the spaced storage areas, the ladder system comprising:
- a pair of spaced storage areas with a central aisle laterally between said storage areas, said central aisle having a floor;
- a ladder received in said aisle and adapted to contact the floor;
- a first guide track and a second guide track, one of said guide tracks extending longitudinally along each of said spaced storage areas, said ladder being mounted for longitudinal movement along both of said guide tracks and for stopping at any location along said guide tracks, said ladder being also mounted for lateral movement between said spaced storage areas at said any location;
- a first rod extending along a lateral axis, said first rod being coupled to said first and second guide tracks for longitudinal movement along said guide tracks;
- a pair of spaced rollers attached to said ladder for coupling said ladder to said first rod, said ladder being movable laterally along said first rod between said first and second guide tracks, said rollers being spaced apart at a distance that is generally the diameter of said first rod, said first rod being interposed between said pair of rollers, said rollers cooperatively gripping said first rod and guiding said ladder for lateral and pivoting movement;
- a pair of laterally spaced sidewalls, one of said guide tracks being associated with one of said sidewalls, said first rod being rigidly secured to said sidewalls and extending between said sidewalls; and
- a second rod rigidly secured to said sidewalls and extending between said sidewalls providing increased stability.
- 5. A ladder system as recited in claim 4, wherein said pair of rollers have curved surfaces received on said first rod corresponding to the outer periphery of a cross section of said first rod such that said rollers may pivot about said first rod.
