Portable and collapsible table structure
View Patent ↗A portable and collapsible table structure comprises a tabletop, a table frame, and a plurality of folding legs pivotally attached to the table frame. The tabletop is independently collapsed to a bundled condition, for example, by folding or rolling. Similarly, the table frame and the folding legs are collapsed so as to minimize the amount of space taken up by the collapsed and bundled table frame and legs. The bundled tabletop and the collapsed table frame and legs can be further bundled or packed together for transport and/or storage. The table frame comprises adjustable members that permit the size and footprint of the table frame to be expanded to multiple usable table sizes without compromising the size of the collapsed and bundled table. The folding legs may be adjustable to reduce the size taken up by the legs in the compressed and bundled condition of the table.
1. A portable and collapsible table comprising:
a tabletop; and
a supporting structure comprising:
a table frame comprising a pair of parallelly disposed telescoping rail members, wherein each rail member comprises an outer rail member and an inner rail member disposed within the outer rail member for telescoping movement relative thereto such that said table frame is adjustable to varying longitudinal sizes; and
at least two leg assemblies each being pivotally connected to the table frame, wherein each leg assembly comprises a first leg and a second leg pivotally connected together, said leg assembly being movable between an open position and a closed position wherein in said open position, the first and second legs being disposed in a generally X-shaped condition, and wherein in said closed position, the first and second legs being disposed in a generally parallel condition;
wherein said tabletop and said supporting structure are collapsible to a portable condition.
2. The table according to claim 1 , wherein the outer rail member defines an interior cavity substantially extending the entire length of the outer rail member that is not blocked by any structural components of the table along the length of the outer rail member such that the inner rail member may be telescoped within the interior cavity along substantially the entire length of the interior cavity.
3. The table according to claim 1 , wherein each of the first and second legs is extendable so as to adjust the length of each said leg.
4. The table according to claim 3 , wherein each of said first and second legs further comprises a telescoping leg member disposed within the lower portion of each said leg, wherein said telescoping leg member may be moved to adjust the length of each said leg.
5. The table according to claim 1 wherein said at least two leg assemblies comprise a first leg assembly and a second leg assembly pivotally connected at a respective first and second ends of the table frame by connecting elbows such that the first and second leg assemblies may be folded inwardly and under the table frame in alternating sequence during collapsing of the supporting structure so that the table frame and each leg assembly are generally disposed in parallel relationship to one another.
6. The table according to claim 1 wherein said at least two leg assemblies comprise a first leg assembly and a second leg assembly pivotally connected at a respective first and second ends of the table frame by reverse connecting elbows such that the first and second leg assemblies may be folded outwardly and over the table frame in alternating sequence during collapsing of the supporting structure so that the table frame and each leg assembly are generally disposed in parallel relationship to one another.
7. The table according to claim 1 , further comprising at least one locking member attached between the table frame and a leg.
8. The table according to claim 7 , wherein the at least one locking member comprises a locking member is attached between each leg of each leg assembly and the table frame.
9. The table according to claim 8 , wherein each locking member remains attached between the table frame and a corresponding leg during collapsing of the supporting assembly to a portable condition.
10. The table according to claim 8 , wherein each locking member is detachable from at least one of the table frame or the leg to which it is attached for collapsing of the supporting structure to a portable condition.
11. The table according to claim 1 , wherein the tabletop is removable from the supporting structure such that the tabletop is independently collapsible from the supporting structure when the tabletop is removed from the supporting structure.
12. The table according to claim 1 wherein said at least two leg assemblies comprise a first leg assembly pivotally connected at the ends of the outer rail members of the parallelly disposed telescoping rail members and a second leg assembly pivotally connected at the ends of the inner rail members of the parallelly disposed telescoping rail members.
13. A portable and collapsible table comprising:
a tabletop; and
a supporting structure comprising:
a table frame comprising a pair of parallelly disposed telescoping rail members;
at least two leg assemblies each being pivotally connected to the table frame, wherein each leg assembly comprises a first leg and a second leg pivotally connected together, said leg assembly being movable between an open position and a closed position wherein in said open position, the first and second legs being disposed in a generally X-shaped condition, and wherein in said closed position, the first and second legs being disposed in a generally parallel condition; and
a locking member attached between each leg of each leg assembly and the table frame;
wherein said tabletop and said supporting structure are collapsible to a portable condition.
14. The table according to claim 13 , wherein each locking member remains attached between the table frame and a corresponding leg during collapsing of the supporting assembly to a portable condition.
15. The table according to claim 13 , wherein the tabletop is removable from the supporting structure such that the tabletop is independently collapsible from the supporting structure when the tabletop is removed from the supporting structure.
16. The table according to claim 13 , wherein each rail member comprises an outer rail member and an inner rail member disposed within the outer rail member for telescoping movement relative thereto, said outer rail member defining an interior cavity substantially extending the entire length of the outer rail member that is not blocked by a mounting provided on the outer rail member for attaching a respective locking member to the outer rail member such that said mounting does not interfere with the telescoping movement of the respective inner rail member within the interior cavity.
17. The table according to claim 16 , wherein the mounting comprises a rivet boss projecting outwardly from the exterior surface of each outer rail member that receives a rivet connection to attach the locking member to the outer rail member.
