Abstract

A foldable table includes first and second panels, first and second mounting assemblies coupled respectively with the first and second panels, and first and second leg assemblies coupled respective with the first and second mounting assemblies. Each of the first and second panels is formed with upper and lower panel surfaces spaced apart at a first distance. Each of the first and second panels is also formed with a ridge or protrusions or both of the ridge and protrusions. A lower surface of the ridge is spaced apart from the upper panel surface at a second distance equal to or less than two times the first distance. A lower surface of each protrusion is spaced apart from the upper panel surface at a third distance equal to or less than 1.5 times the first distance. Thus, when folded, the table has a minimized thickness.

First claim

What is claimed is:

1. A foldable table comprising:
a first panel and a second panel, each respective panel in the first and second panels comprising:
an upper panel surface;
a lower panel surface spaced apart from the upper panel surface at a first distance; and
a plurality of protrusions, a plurality of depressions, and a plurality of ribs monolithically formed with the respective panel across at least a portion of the respective panel, each of the plurality of protrusions protruding downward from the lower panel surface and comprising a lower protrusion surface below the lower panel surface and spaced apart from the upper panel surface at a third distance, wherein the third distance is equal to or less than 1.5 times the first distance, wherein each of the plurality of depressions recesses from the lower panel surface toward the upper panel surface, and wherein each respective protrusion in at least a subset of the plurality of protrusions is adjacent to at least two corresponding protrusions in the plurality of protrusions, adjacent to at least two corresponding depressions in the plurality of depressions, and connected to the adjacent corresponding protrusions by at least two ribs in the plurality of ribs;

a first mounting assembly and a second mounting assembly pivotally coupled with each other at proximal sides of the first and second mounting assemblies, wherein the first mounting assembly is disposed below the lower panel surface of the first panel and coupled with the first panel, and the second mounting assembly is disposed below the lower panel surface of the second panel and coupled with the second panel; and
a first leg assembly and a second leg assembly, wherein the first leg assembly is pivotally coupled with the first mounting assembly at a distal side of the first mounting assembly, and the second leg assembly is pivotally coupled with the second mounting assembly at a distal side of the second mounting assembly.

2. The foldable table of claim 1 , wherein each respective panel further comprises:
a ridge monolithically formed with the respective panel at or adjacent to an edge of the respective panel, the ridge extending downward beyond the lower panel surface and comprising a lower ridge surface spaced apart from the upper panel surface at a second distance, wherein the second distance is equal to or less than two times the first distance.

3. The foldable table of claim 1 , wherein the lower panel surface is substantially parallel to the upper panel surface.

4. The foldable table of claim 1 , further comprising:
a first supporting assembly coupled with the first leg assembly and first mounting assembly and configured to control rotation of the first leg assembly with respect to the first mounting assembly; and
a second supporting assembly coupled with the second leg assembly and second mounting assembly and configured to control rotation of the second leg assembly with respect to the second mounting assembly.

5. The foldable table of claim 1 , wherein the lower protrusion surface of a protrusion in the plurality of protrusions is substantially flat, arched, or dome-shaped.

6. The foldable table of claim 1 , wherein the plurality of protrusions is formed across at least a majority portion of the respective panel.

7. The foldable table of claim 1 , wherein protrusions in the of the plurality of protrusions are arranged substantially uniformly across the portion of the respective panel.

8. The foldable table of claim 1 , wherein depressions in the of the plurality of depressions are arranged alternately with protrusions in the of the plurality of protrusions across the portion of the respective panel, and wherein the plurality of depressions and the plurality of protrusions collectively enhance the strength of the respective panel.

9. The foldable table of claim 1 , wherein
each of the plurality of ribs protrudes downward from the lower panel surface of the respective panel.

10. The foldable table of claim 9 , wherein each of the plurality of ribs comprises a lower rib surface or rim spaced apart from the upper panel surface at a fourth distance that is substantially the same as the third distance.

11. The foldable table of claim 9 , wherein each of the plurality of ribs comprises a lower rib surface or rim spaced apart from the upper panel surface at a fourth distance that is substantially the same as the third distance.

12. The foldable table of claim 1 , wherein each respective protrusion in at least the subset of the plurality of protrusions is adjacent to at least three corresponding protrusions in the plurality of protrusions, adjacent to at least three corresponding depressions in the plurality of depressions, and connected to the adjacent corresponding protrusions by at least three ribs in the plurality of ribs.
