Abstract
The present disclosure relates to stair systems and methods for allowing stair movement, including rotational movement, between building levels while maintaining the structural integrity of the stair system for safe egress passage and ingress passage. 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. 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 can reduce stair damage during building movement whether it is from wind, thermal, explosive, or seismic activity, and/or any other type of suitable force or experience, as the present disclosure allows for rotational movement, longitudinal movement, or a combination thereof. A landing system is provided with a single-point connection device allowing rotation around a vertical axis, i.e rotational movement in a horizontal XY plane.
Claims (25)
1. A stair system, comprising: a first landing connection system comprising a single-point connection device configured for rotational movement in a combination of an X-direction and a Y-direction; a second landing connection system comprising at least one secondary movement connection device configured for longitudinal movement in at least one of the X-direction and the Y-direction.
2. The stair system of claim 1, wherein the single-point connection device is centrally located within the first landing connection system.
3. The stair system of claim 1, wherein the single-point connection device includes at least one of a shaft configuration, a pin-type configuration, a nut-and-bolt configuration, a ball-and-socket configuration, a hitch-type configuration, a ball-joint-rod-end configuration, a swivel joint configuration, or a configuration in which one or more structural shapes fit together.
4. The stair system of claim 3, wherein the single-point connection device further includes a coupler and a cross channel.
5. The stair system of claim 1, wherein the at least one secondary movement connection device includes a slotted connector, a track system connector, a guide rail connector, a wheeled connector, a roller connector, a slide connector, or a plate connector.
6. A stair system, comprising: a first landing connection system comprising: a single-point connection device configured for rotational movement in a combination of an X-direction and a Y-direction; and a secondary movement connection device operatively connected with the single-point connection device and configured for longitudinal movement in at least one of the X-direction and the Y-direction.
7. The stair system of claim 6, wherein the single-point connection device includes at least one of a shaft configuration, a pin-type configuration, a nut-and-bolt configuration, a ball-and-socket configuration, a hitch-type configuration, a ball-joint-rod-end configuration, a swivel joint configuration, or a configuration in which one or more structural shapes fit together.
8. The stair system of claim 7, wherein the secondary movement connection device comprises a first face having a slot therein, and wherein the single-point connection device is at least partially disposed through the slot to operatively connect the secondary movement connection device with the single-point connection device.
9. The stair system of claim 8, wherein the single-point connection device is centrally located within the first face.
10. A moveable stair system, comprising: a staircase having one or more stairs; a first landing connection system disposed at a first end of the staircase; and a second landing connection system disposed at a second end of the staircase, wherein the first end is opposite the second end, wherein the first landing connection system includes a single-point connection device configured for movement of the staircase in a rotational direction, wherein the movement in the rotational direction is movement in the X- direction and in the Y-direction, wherein the second landing connection system comprises a secondary movement connection device configured for movement of the staircase in a longitudinal direction, and wherein the movement in the longitudinal direction includes movement in at least one of the X-direction and the Y-direction.
11. The moveable stair system of claim 10, wherein the single-point connection device is centrally located within the first landing connection system.
12. The moveable stair system of claim 10, wherein the single-point connection device includes at least one of a shaft configuration, a pin-type configuration, a nut-and-bolt configuration, a ball-and-socket configuration, a hitch-type configuration, a ball-joint-rod- end configuration, a swivel joint configuration, or a configuration in which one or more structural shapes fit together.
13. The moveable stair system of claim 12, wherein the single-point connection device further includes a coupler and a cross channel.
14. The moveable stair system of claim 10, wherein the secondary movement connection device includes a slotted connector, a track system connector, a guide rail connector, a wheeled connector, a roller connector, a slide connector, or a plate connector.
15. The moveable stair system of claim 10, wherein the first landing connection system is further operatively connected to a first landing, and wherein the second landing connection system is further operatively connected to a second landing.
16. The moveable stair system of claim 10, further comprising a landing plate operatively connected to the first landing connection system and configured to cover a gap disposed between the staircase and a first landing.
17. A moveable stair system, comprising: a staircase having one or more stairs; and a first landing connection system disposed at a first end of the staircase, wherein the first end is opposite a second end of the staircase, and wherein the first landing connection system comprises: a single-point connection device configured for rotational movement in a combination of an X-direction and a Y-direction; and a secondary movement connection device operatively connected with the single-point connection device and configured for longitudinal movement in at least one of the X-direction and the Y-direction.
18. The moveable stair system of claim 17, wherein the single-point connection device includes at least one of a shaft configuration, a pin-type configuration, a nut-and-bolt configuration, a ball-and-socket configuration, a hitch-type configuration, a ball-joint-rod- end configuration, a swivel joint configuration, or a configuration in which one or more structural shapes fit together.
19. The moveable stair system of claim 18, wherein the secondary movement connection device comprises a first face having a slot therein, and wherein the single-point connection device is at least partially disposed through the slot to operatively connect the secondary movement connection device with the single-point connection device.
20. The moveable stair system of claim 19, wherein the single-point connection device is centrally located within the first face.
21. The moveable stair system of claim 17, wherein the secondary movement connection device includes a slotted connector, a track system connector, a guide rail connector, a wheeled connector, a roller connector, a slide connector, or a plate connector.
22. The moveable stair system of claim 17, further comprising a landing plate configured to cover a gap disposed between the staircase and a first landing.
23. The moveable stair system of claim 17, wherein the first landing connection system is further operatively connected to a first landing.
24. The stair system of claim 1 or claim 6, the stair system being substantially as hereinbefore described with reference to the accompanying drawings.
25. The moveable stair system of claim 10 or claim 17, the moveable stair system being substantially as hereinbefore described with reference to the accompanying drawings.
