Abstract
The present disclosure relates to a stair system (700) for allowing stair movement between building levels while maintaining the structural integrity of the stair system for safe egress passage. The stair system (700) of the present disclosure comprises a first movement system (710) configured to couple with a bottom landing of a first stair set that allows for movement in a first direction, and a second movement system (730) configured for coupling with a top landing of the first stair set that allows for movement in a second direction different from the first direction. The provided stair system (700) allows for independent movement of the surrounding building walls, landings, floor slabs, and/or any other portion of the surrounding building structure or stair system. The present disclosure is configured such to reduce stair damage during building movement whether it is from wind, thermal, or seismic activity, and/or any other type of suitable force or experience, as the present disclosure allows for directional movement, or a combination thereof, including tension and compression, lateral, or vertical movement.
Claims (8)
1. A stair system, comprising: a first movement system, comprising: 5 a first landing connector comprising a first guide rail and at least one first foot coupled with the first guide rail; a first support beam operatively coupled with the first guide rail, such that the first support beam slides along the first guide rail; and a first connection system for coupling the at least one first foot with at least one of a 10 first stair, a first landing, or a first ground location; a second movement system, comprising: a second landing connector comprising a second guide rail and at least one second foot coupled with the second guide rail; a second support beam operatively coupled with the second guide rail, such that the 15 second support beam slides along the second guide rail; and a second connection system for coupling the at least one second foot with at least one of a second stair, a second landing, or a second ground location; wherein the first movement system allows for movement in a first direction, wherein the second movement system allows for movement in a second direction 20 different to the first direction, wherein the first movement system is configured for coupling with a bottom landing of a first stair set and the second movement system is configured for coupling with a top landing of the first stair set.
2. The stair system of claim 1, further comprising: a third movement system, comprising: 25 a third landing connector comprising a third guide rail and at least one third foot coupled with the third guide rail; a third support beam operatively coupled with the third guide rail, such that the third support beam slides along the third guide rail; and a third connection system for coupling the at least one third foot with at least one of a third stair, a third landing, or a third ground location; 5 a fourth movement system, comprising: a fourth landing connector comprising a fourth guide rail and at least one fourth foot coupled with the fourth guide rail; a fourth support beam operatively coupled with the fourth guide rail, such that the fourth support beam slides along the fourth guide rail; and 10 a fourth connection system for coupling the at least one fourth foot with at least one of a fourth stair, a fourth landing, or a fourth ground location; wherein the third movement system allows for movement in the second direction, wherein the fourth movement system allows for movement in the first direction, wherein the third movement system is configured for coupling with the top landing of the first 15 stair set and the fourth movement system is configured for coupling with a top landing of the second stair set.
3. The stair system of claim 2, wherein the second stair set is configured to move in both a tension direction and a compression direction.
4. The stair system of claim 1, wherein the first support beam or the second support 20 beam comprises at least one of a metal, a plastic, or a glass.
5. The stair system of claim 1, wherein the first support beam or the second support beam comprises a square shape, a rectangular shape, an L-shape, or a double-L-shape.
6. The stair system of claim 1, further comprising a lubricant adapted to be utilized with the stair system.
7. The stair system of claim 1, wherein the first stair set is configured to move in both a tension direction and a compression direction.
8. The stair system of claim 1, wherein the second direction is perpendicular to the first direction.
