Abstract
The present disclosure relates to stair systems (100) and methods for allowing stair movement between building levels while maintaining the structural integrity of the stair system for safe egress passage. The provided stair system comprises a first connector (106), and a sliding body (118) operatively connected with the first connector. The sliding body comprises a first end and a second end, an upper connector (126) operatively connected with the sliding body, and a lower connector (128). The upper connector is operatively connected and telescopically disposed within the lower connector, and a second connector (140) operatively connected with the lower connector at a first connection point (142). The systems and methods of the present disclosure allow 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 embodiments of the present disclosure are suitable for use in both new constructions as well as in existing constructions for retrofit applications to allow for movement between levels, landings, or within stairwell structures. The present disclosure reduces 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 (16)
1. A stair system, comprising: a first connector; a sliding body operatively connected with the first connector, wherein the sliding body comprises a first end and a second end, wherein the second end is opposite the first end; an upper connector operatively connected with the sliding body; a lower connector, wherein the upper connector is operatively connected and telescopically disposed within the lower connector; and a second connector operatively connected with the lower connector at a first connection point.
2. The stair system of claim 1, wherein the second connector comprises a shoe and a mounting portion connected with the shoe.
3. The stair system of claim 1, wherein the first connector is a landing connector and the second connector is a stair connector.
4. The stair system of claim 1, wherein the sliding body is cylindrical.
5. The stair system of claim 1, wherein the first connector comprises a first body having a base for connection with a stair or a landing, a first arm, and a second arm, wherein each of the first arm and the second arm extend outward from the base.
6. The stair system of claim 5, wherein a first length between the first end of the sliding body and the second end of the sliding body is greater than a second length between the first arm of the first body and the second arm of the first body.
7. The stair system of claim 6, wherein the upper connector is operatively connected with the sliding body at an approximate midpoint of the sliding body.
8. The stair system of claim 5, wherein the sliding body extends through each of the first arm and the second arm such that the first arm and the second arm support the sliding body.
9. The stair system of claim 8, wherein the upper connector is operatively coupled with the sliding body between the first arm and the second arm.
10. The stair system of claim 8, wherein each of the first arm and the second arm comprise a circular cut-out therethrough allowing sliding movement and rotational movement of the sliding body therein.
11. The stair system of claim 1, further comprising a first restriction body operatively disposed through each of the upper connector and the lower connector.
12. The stair system of claim 11, wherein the first restriction body comprises a pin.
13. The stair system of claim 12, wherein the upper connector comprises a first slot therethrough and the lower connector comprises a second slot therethrough, wherein the pin is disposed through each of the first slot and the second slot to allow for telescopic movement of the upper connector with respect to the lower connector.
14. The stair system of claim 1, further comprising a pad coupled with the second connector, wherein the pad comprises a low friction material, and wherein the pad is configured to be disposed between the second connector and a stair support.
15. The stair system of claim 1, further comprising a pad disposed between the upper connector and the lower connector, wherein the pad comprises a low friction material.
16. The stair system of claim 1, wherein the sliding body is configured for movement in a first lateral direction along a longitudinal axis of the sliding body and rolling movement about the longitudinal axis of the sliding body, wherein the lower connector is configured for rotational movement about the first connection point, and wherein the lower connector and the second connector are configured for movement relative to the upper connector in a second lateral direction perpendicular to the first lateral direction.
