Abstract

A collapsible table includes upper and lower pole members, a hub, and a tabletop. The upper and lower pole members are pivotally attached to the hub. The upper pole members extend upward and apart from each other from the hub when in their operable configuration and extend downward from the hub and generally parallel to each other when in their stowage configuration. The lower pole members extend downward and apart from each other from the hub when in their operable configuration and extend downward from the hub and generally parallel to each other when in their stowage configuration. The tabletop is removably attachable to the upper pole members and can be suspended by and between the upper pole members when the upper and lower pole members are in their operable configurations.

First claim

What is claimed is:

1. A collapsible table comprising:
at least three upper pole members;
at least three lower pole members;
a hub comprising an upper hub piece and a lower hub piece, the upper hub piece and the lower hub piece being fixed in position relative to each other and secured to each other via a plurality of resilient locking tabs that extend from at least one of the upper and lower hub pieces, each of the upper pole members being pivotally attached to the upper hub piece in a manner such that the upper pole members can be adjusted from an operable configuration to a stowage configuration, the upper pole members extending upward and diverging apart from each other from the hub when the upper pole members are in their operable configuration, the hub preventing the upper pole members from pivoting upward beyond their operable configuration, the upper pole members extending downward from the hub and generally parallel to each other when the upper pole members are in their stowage configuration, the lower pole members being pivotally attached to the lower hub piece in a manner such that the lower pole members can be adjusted from an operable configuration to a stowage configuration, the lower pole members extending downward and diverging apart from each other from the hub when the lower pole members are in their operable configuration, the hub preventing the lower pole members from pivoting upward beyond their operable configuration, the lower pole members extending downward from the hub and generally parallel to each other when the lower pole members are in their stowage configuration;
a tabletop, the tabletop being removably attachable to the upper pole members and being adapted to be suspended by and between the upper pole members when the upper and lower pole members are in their operable configuration.

2. A table in accordance with claim 1 wherein the tabletop is pliable and is stretched taut between the upper pole members when the upper pole members are in their operable configuration.

3. A table in accordance with claim 2 wherein the tabletop is adapted to prevent the upper pole members from pivoting down from their operable configuration when the tabletop is attached to the upper pole members.

4. A table in accordance with claim 1 wherein the hub comprises a plurality of detents that are configured to releaseably secure the upper and lower pole members in their operable configuration.

5. A table in accordance with claim 4 wherein the detents are configured to releaseably secure the upper and lower pole members in their stowage configuration.

6. A table in accordance with claim 1 wherein the hub defines a vertical center axis and the upper and lower pole members are circumferentially spaced about the center axis in a manner such that the upper pole members alternate with the lower pole members circumferentially about the center axis.

7. A table in accordance with claim 1 wherein the table comprises four and only four of the upper pole members and four and only four of the lower pole members.

8. A table in accordance with claim 1 wherein the resilient locking tabs are part of the upper hub piece and extend down therefrom over exterior surfaces of the lower hub piece.

9. A table in accordance with claim 1 wherein the upper hub piece comprises a plurality of detents that are configured to releaseably secure the upper pole members in their operable configuration, and the lower hub piece comprises a plurality of detents that are configured to releaseably secure the upper pole members in their stowage configuration.

10. A method of collapsing a table from an operable configuration to a stowage configuration, the table comprising at least three upper pole members, at least three lower pole members, a hub, and a tabletop, the hub comprising an upper hub piece and a lower hub piece, each of the upper pole members being pivotally attached to the upper hub piece, each of the lower members being pivotally attached to the lower hub piece, the upper hub piece and the lower hub piece being fixed in position relative to each other and secured to each other via a plurality of resilient locking tabs that extend from at least one of the upper and lower hub pieces, the tabletop being suspended by and between the upper pole members, the method comprising:
detaching the tabletop from the upper pole members;
pivoting the upper pole members downward relative to the hub from an operable configuration to a stowage configuration, the upper pole members extending upward and diverging apart from each other from the hub when the upper pole members are in their operable configuration, the upper pole members extending downward from the hub and generally parallel to each other when the upper pole members are in their stowage configuration; and
pivoting the lower pole members downward relative to the hub from an operable configuration to a stowage configuration, the lower pole members extending downward and diverging apart from each other from the hub when the lower pole members are in their operable configuration, the lower pole members extending downward and generally parallel to each other from the hub when the lower pole members are in their stowage configuration.

11. A method in accordance with claim 10 wherein the detaching of the tabletop from the upper pole members allows the upper pole members to be pivoted downward.

12. A method in accordance with claim 11 wherein the hub comprises detents that releaseably secure the upper and lower pole members in their operable configurations, and the pivoting of the upper and lower pole members requires overcoming torques sufficient to overcome the detents.

13. A method in accordance with claim 12 wherein the detents automatically releaseably secure the upper and lower pole members in their stowage configurations after the upper and lower pole members have been pivoted.

14. A method in accordance with claim 10 wherein the tabletop is pliable and the detaching of the tabletop from the upper pole members includes at least one of resiliently bending the upper pole members and stretching the tabletop.

15. A method in accordance with claim 10 wherein the resilient locking tabs are part of the upper hub piece and extend down therefrom over exterior surfaces of the lower hub piece.
