Abstract

An articulating table can be easily adjusted by meeting participants, thereby suiting a wide range of meeting conditions without lifting, carrying or requiring specialized help. Rollers and/or electric motors make this transition easy. The articulating table includes two or more leaves coupled to each other by a large horizontal pivot. These leaves can be moved to different angles relative to each other, allowing for changes in configuration and capacity. The articulation can be accomplished using a rule joint, wherein the pivoting members are attached with offsets allowing the leaves to be placed in the same plane. The rule joint is divided into two or more parts, each attached to a leaf. These pivot parts are circular and have either a protrusion or depression concentric to their center, which fits into a corresponding part on the other member. This male/female arrangement provides a bearing surface and maintains alignment as the leaves pivot. Intermediate leaves, if filled, have a hole in their pivot member to accommodate the bearing assembly. Connectors and overlapping slots in the inner layers hold the joint together and limit motion as necessary. A split base housing rollers supports the other ends of the leaves.

Claims

1. An articulating table comprising:

a circular section including a horizontal pivot and having a top surface; and

two or more leaves extending outward from the circular section and couplable to each other by rotation via the horizontal pivot to form a common planar surface with the top surface of the circular section when coupled to each other.

2. The table according to claim 1, wherein the two or more leaves can be moved to different angles relative to each other allowing for changes in configuration and capacity.

3. The table according to claim 1, wherein the horizontal pivot comprises a rule joint including a plurality of pivoting members that are attached with offsets allowing the two or more leaves to be placed in a same plane.

4. The table according to claim 3, wherein the rule joint is divided into two or more pivot parts, each attached to one of the two or more leaves.

5. The table according to claim 4, wherein the two or more pivot parts are circular shaped and have either a protrusion or depression concentric to their centers, which fits into a corresponding part on another of the two or more pivot parts, wherein a resulting male/female arrangement provides a bearing surface and maintains alignment as the two or more leaves pivot.

6. The table according to claim 5, further comprising a plurality of intermediate leaves each having a hole in their pivot member to accommodate the bearing assembly.

7. The table according to claim 6, further comprising a plurality of connectors and overlapping slots in inner layers that hold the joint together and limit articulation.

8. The table according to claim 1, further comprising a split base housing two or more rolling members, each of the two or more rolling members supporting one end of the two or more leaves.

9. The table according to claim 1, further comprising a table edge around an exterior of the table, said table edge being coped into an opposite member at a perimeter of a rotary section, allowing for a smooth and unbroken edge profile as the table articulates.

10. An apparatus comprising a horizontal pivot including a plurality of pivot elements stacked vertically on top of each other, a top one of said plurality of pivot elements having a top surface, said plurality of pivot elements being rotatable about the horizontal pivot relative to each other, each of said pivot elements having a substantially circular shape at a first end and a protruding section at a second end, said protruding sections each having a top surface being in a same horizontal plane as all other top surfaces of all other protruding sections, wherein when the plurality of pivot elements are rotated about the horizontal pivot into a first position two or more of said protruding leaves meet to form a common planar surface with the top surface of the top one of the plurality of pivot elements and when rotated about the horizontal pivot into a second position each of said protruding leaves separate to form a plurality of separate horizontal surfaces in a common plane.

12. The apparatus according to claim 10, wherein the plurality of pivot elements comprises two pivot elements.

13. The apparatus according to claim 10, wherein the plurality of pivot elements comprises four pivot elements.

14. The apparatus according to claim 10, further comprising a base in which the horizontal pivot is disposed supporting the stack of pivot elements and a base for each of the protruding sections supporting the protruding sections, wherein in the first position the bases of the protruding sections meet to form a common base and in the second position the bases of the protruding sections split to form a base for its associated protruding section.

11. An apparatus comprising a horizontal pivot including a plurality of pivot elements stacked vertically on top of each other, said plurality of pivot elements being rotatable about the horizontal pivot relative to each other, each of said pivot elements having a substantially circular shape at a first end and a protruding section at a second end, said protruding sections each being in a same horizontal plane as all other protruding sections, wherein when the plurality of pivot elements are rotated about the horizontal pivot into a first position two or more of said protruding leaves meet to form one or more combined horizontal surfaces and when rotated about the horizontal pivot into a second position each of said protruding leaves separating to form a plurality of separate horizontal surfaces;

and

a motor mounted in the horizontal pivot and automatically rotating the plurality of pivot elements with respect to each other from the first position to the second position.

15. An apparatus for creating a plurality of work surfaces comprising:

a plurality of surface elements, each of said plurality of surface elements having two parts, a first part having a first shape and being stackable vertically with all other first parts of the plurality of surface elements all of which are aligned on a common center, a second part having a second shape and being alignable horizontally with all other second parts to form a common planar surface with all other second parts and a top of the stack of first parts; and

a shaft attached to at least one of the plurality of surface elements enabling rotation of the plurality of surface elements with respect to each other around the common center so that in a first position around the common center the plurality of surface elements align to form the common planar surface and in one or more others positions around the common center the plurality of surface elements separate to form two or more separate horizontal surfaces in a common plane.

16. The apparatus according to claim 15, further comprising a common base housing the shaft and supporting the stack of first parts of the plurality of surface elements.

17. The apparatus according to claim 16, further comprising a split base supporting the plurality of second parts of the plurality of surface elements when in the first position and splitting to support each of the plurality of second parts of the plurality of surface elements when in the one or more other positions.

19. The apparatus according to claim 15, wherein the plurality of surface elements comprises two surface elements.

20. The apparatus according to claim 15, wherein the plurality of surface elements comprises four or more surface elements.

18. An apparatus for creating a plurality of work surfaces comprising:

a plurality of surface elements, each of said plurality of surface elements having two parts, a first part having a first shape and being stackable vertically with all other first parts of the plurality of surface elements all of which are aligned on a common center, a second part having a second shape and being alignable horizontally with all other second parts to form a common horizontal surface with all other second parts and a top of the stack of first parts; and

a shaft attached to at least one of the plurality of surface elements enabling rotation of the plurality of surface elements with respect to each other around the common center so that in a first position around the common center the plurality of surface elements align to for the common horizontal surface and in one or more others positions around the common center the plurality of surface elements separate to form two or more separate horizontal surfaces; and

a motor mounted in the common base and coupled to the shaft and automatically rotating the plurality of surface elements with respect to each other from the first position to the one or more other positions.
