Modular walls with seismic-shiftability

1. A shiftable frame for accommodating movement of structural portions of a building that secure the shiftable frame, the shiftable frame comprising:

a first frame section including a plurality of first vertical supports and one or more first horizontal supports;

a second frame section including a plurality of second vertical supports and one or more second horizontal supports;

one or more brackets, each of the one or more brackets having a first end thereof pivotally connected to the first frame section and a second end thereof pivotally connected to the second frame section;

a connector rod disposed between the first frame section and the second frame section and extending between opposing ends of the shiftable frame, wherein the connector rod limits lateral movement of the first frame section and the second frames section while allowing the first frame section and the section frame section to move vertically relative to one another and relative to the connector rod; and

one or more knuckle brackets movably connected to the connector rod, the one or more knuckle brackets being connectable to one or more support structures or other shiftable frames, wherein the movable connection between the one or more knuckle brackets and the connector rod enables the one or more knuckle brackets and the connector rod to move independent of one another.

2. A shiftable frame as recited in claim 1 , wherein the first frame section at least partially defines a first side of a wall module and the second frame section at least partially defines an opposing second side of the wall module.

3. A shiftable frame as recited in claim 1 , wherein the one or more first horizontal supports comprise one or more stringers.

4. A shiftable frame as recited in claim 3 , wherein the one or more stringers comprise the connection features.

5. A shiftable frame as recited in claim 1 , wherein the one or more first horizontal supports comprise one or more torsion bars connected between the adjacent vertical supports of the plurality of first vertical supports.

6. A shiftable frame as recited in claim 1 , wherein the shiftable frame is selectively reconfigurable between a collapsed configuration and an expanded configuration.

7. A shiftable frame as recited in claim 1 , further comprising one or more yokes connected between the first frame section and the second frame section, wherein the one or more yokes are configured to rotate upon relative movement between the first frame section and the second frame section.

8. A shiftable frame as recited in claim 1 , further comprising one or more fasteners that connect the one or more brackets to the first and second frame sections of the shiftable frame, wherein one or more of the first frame section and the second frame section includes connection features connectable to corresponding features of a panel, and wherein the one or more fasteners press the one or more brackets against the first and second frame sections with a frictional force that restrains relative movement between the first and second frame sections, such that the frictional force between the brackets and the first and second frame sections dictates the amount force required to pivot the first and second frame sections relative to the brackets.

9. A shiftable frame as recited in claim 7 , wherein the connector rod is disposed at least partially within the one or more yokes to limit lateral movement of the shiftable frame.

10. A shiftable frame as recited in claim 1 , wherein each of the one or more knuckle brackets includes a protrusion having an approximately spherical shape.

11. A shiftable wall module for at least partially defining one or more individual spaces within a building, the shiftable wall module comprising:

a first frame section including a first vertical support and a first stringer;

a second frame section including a second vertical support;

a bracket pivotally connected to the first vertical support and the second vertical support in a manner that the first frame section and the second frame section are movable relative to each other;

at least one panel removably connected to the stringer;

one or more yokes connected between the first frame section and the second frame section, each of the one or more yokes having an opening or cutout, wherein the one or more yokes are configured to rotate upon relative movement between the first frame section and the second frame section;

a connector rod disposed between the first frame section and the second frame section and extending between opposing ends of the shiftable frame, the connector being disposed within the opening or cutout of the one or more yokes, wherein the connector rod limits lateral movement of the first frame section and the second frames section while allowing for relative movement between the first frame section and the section frame section; and

one or more knuckle brackets movably connected to the connector rod, the one or more knuckle brackets being connectable to one or more support structures or other shiftable frames, wherein the movable connection between the one or more knuckle brackets and the connector rod enables the one or more knuckle brackets and the connector rod to move independent of one another.

12. A shiftable wall module as recited in claim 11 , wherein the bracket comprises a hole and a slot therethrough.

13. A shiftable wall module as recited in claim 12 , wherein the bracket is pivotally connected to the first frame section via the hole.

14. A shiftable wall module as recited in claim 12 , wherein the bracket is pivotally connected to the second frame section via the slot.

15. A shiftable wall module as recited in claim 14 , wherein the second frame second is connectable to the bracket at multiple positions along the length of the slot to adjust the distance between the first frame section and the second frame section.

16. A shiftable wall module as recited in claim 11 , wherein the at least one panel comprises (i) one or more panels removably connected to the first frame section to at least partially define a first side of the shiftable wall module, and (ii) one or more panels removably connected to the second frame section to at least partially define an opposing second side of the shiftable wall module.

17. A method of installing a wall module in a building, the method comprising:

positioning a bottom end of a first frame section of a frame on a floor of the building;

tilting the frame toward an upright orientation;

pressing a second section of the frame against the floor, the second section being movably connected to the first section;

moving the second section in a direction generally parallel to the first section;

positioning the frame in the upright orientation

securing a connector rod between the first frame section and the second frame section such that the connector rod extends between opposing ends of the wall module and such that the connector rod limits lateral movement of the first frame section and the second frames section while allowing the first frame section and the section frame section to move vertically relative to one another and relative to the connector rod; and

securing one or more knuckle brackets between the connector rod and one or more support structures or other wall modules, wherein the one or more knuckle brackets and the connector rod are movably secured together to enable the one or more knuckle brackets and the connector rod to move independent of one another.

18. The method as recited in claim 17 , wherein moving the second frame section in a direction generally parallel to the first frame section results in the first frame section and the second frame section moving away from one another.

19. The method as recited in claim 17 , further comprising securing the frame to a support structure.

20. The method as recited in claim 17 , further comprising securing one or more panels to the frame.
