Abstract

The present disclosure discloses a foldable table comprising a table board and a foot supporting frame. A rear portion of a bottom surface of the table board is rotatably connected to a top portion of the foot supporting frame. The foot supporting frame comprises two supporting rods disposed symmetrically on a left side and a right side of the foldable table and a U-shaped fixed rod. Lower ends of the two supporting rods are respectively rotatably connected to two ends of an opening of the U-shaped fixed rod. When the table board and the foot supporting frame are opened to be in an opened state, the U-shaped fixed rod is supported on ground with the opening of the U-shaped fixed rod facing forward, the two supporting rods are disposed obliquely with respect to the ground, and a side view of the folding table is Z-shaped.

First claim

lower ends of the two supporting rods are respectively rotatably connected to two ends of an opening of the U-shaped fixed rod,
each of the two ends of the opening of the U-shaped fixed rod is disposed with a position-limiting structure,
two oblique linking bars respectively corresponding to the two supporting rods are connected between the table board and the two supporting rods,
an upper end of each of the two oblique linking bars is rotatably connected to a rear portion of a side of the table board,
a lower end of each of the two oblique linking bars is rotatably connected to a sliding sleeve slidably sleeved on each of the two supporting rods,
when the table board and the foot supporting frame are opened to be in an opened state:
the U-shaped fixed rod is supported on ground with the opening of the U-shaped fixed rod facing forward,
the two supporting rods are disposed obliquely with respect to the ground, and
a side view of the folding table is Z-shaped,

when the table board is in a folding process:
the table board is rotated downward around a first connection point at which the table board is connected to the foot supporting frame, and
the table board is folded on the two supporting rods,

when the U-shaped fixed rod is in the folding process:
the U-shaped fixed rod is rotated downward around a second connection point at which the U-shaped fixed rod is connected to the two supporting rods, and
the U-shaped fixed rod is folded on the two supporting rods or on a top surface of the table board,

when the foot supporting frame is opened to be in the opened state, each of the two supporting rods is obliquely disposed on the position-limiting structure with respect to the ground, and
when the table board is opened to be in the opened state, the table board is supported on the two oblique linking bars.

2. The foldable table according to claim 1 , wherein:
when the table board and the foot supporting frame are opened to be in the opened state, a projection surface of a top view of the table board substantially overlaps with the U-shaped fixed rod.

3. The foldable table according to claim 1 , wherein:
the position-limiting structure is a U-shaped block in which an end portion of each of the two supporting rods is disposed, and
the end portion of each of the two supporting rods is rotatably connected to the U-shaped block through a rivet.

4. The foldable table according to claim 3 , wherein:
each of the two ends of the opening of the U-shaped fixed rod is disposed with an outer plastic member,
the outer plastic member is wrapped around the U-shaped block,
each of the lower ends of the two supporting rods is disposed with an inner plastic member, and
the outer plastic member is sleeved outside of the inner plastic member.

5. The foldable table according to claim 4 , wherein:
the foldable table further comprises a table foot locking mechanism connected to at least one of the outer plastic members, and
the U-shaped fixed rod is locked to the table foot locking mechanism when the U-shaped fixed rod is opened to be in the opened state.

6. The foldable table according to claim 1 , wherein:
at least one of the sliding sleeves is disposed with a table board locking mechanism, and
the at least one of the sliding sleeves is locked to the table board locking mechanism when the table board is opened to be in the opened state.

7. The foldable table according to claim 1 , wherein:
the foldable table further comprises a cup holder,
a side of the cup holder is disposed with a C-shaped buckle, and
the C-shaped buckle is buckled to one of the two supporting rods.

8. The foldable table according to claim 7 , wherein:
upper ends of the two supporting rods are connected by a cross rod,
the two supporting rods are telescopic,
at least one buckle member is sleeved on the cross rod and is connected to the bottom surface of the table board,
a side wall of the cup holder comprises a hanging groove,
the at least one buckle member comprises a hanging lug, and
the hanging lug is configured to be locked to the hanging groove.

9. A foldable table, comprising:
a table board, and
a foot supporting frame, wherein:
a rear portion of a bottom surface of the table board is rotatably connected to a top portion of the foot supporting frame,
the foot supporting frame comprises two supporting rods disposed symmetrically on a left side and a right side of the foldable table and a U-shaped fixed rod,
lower ends of the two supporting rods are respectively rotatably connected to two ends of an opening of the U-shaped fixed rod,
each of the two ends of the opening of the U-shaped fixed rod is disposed with an outer hinge,
the lower end of each of the two supporting rods is disposed with an inner hinge,
the outer hinge and the inner hinge are rotatably connected to each other through a rivet,
an inside of the inner hinge is disposed with one or more position-limiting tooth grooves,
an inside of the outer hinge is rotatably connected with a swinging tooth,
the inside of the outer hinge is further disposed with a torsion spring,
when the U-shaped fixed rod is opened to be in an opened state, the swinging tooth is disposed in the one or more position-limiting tooth grooves due to an elastic force of the torsion spring so that the two supporting rods are locked to the U-shaped fixed rod,
when the table board and the foot supporting frame are opened to be in the opened state:
the U-shaped fixed rod is supported on ground with the opening of the U-shaped fixed rod facing forward,
the two supporting rods are disposed obliquely with respect to the ground, and
a side view of the folding table is Z-shaped,

when the table board is in a folding process:
the table board is rotated downward around a first connection point at which the table board is connected to the foot supporting frame, and
the table board is folded on the two supporting rods, and

when the U-shaped fixed rod is in the folding process:
the two supporting rods are rotated rearward around a second connection point at which the U-shaped fixed rod is connected to the two supporting rods, and
the two supporting rods are folded on the U-shaped fixed rod.

10. The foldable table according to claim 9 , wherein:
the foldable table further comprises a pushing piece rotatably sleeved on the rivet,
a first side of the pushing piece facing the swinging tooth comprises a protrusion,
a second side of the pushing piece facing away from the swinging tooth comprises an arc-shaped position-providing groove,
the inner hinge is disposed with a pushing block,
the pushing block is located in the arc-shaped position-providing groove,
the two supporting rods are configured to be rotated frontward to drive the pushing block to rotate about the rivet to correspond to a lower end of the arc-shaped position-providing groove to push the pushing piece to rotate together, so that the swinging tooth is pushed away from the one or more position-limiting tooth grooves, and
the one or more position-limiting tooth grooves are configured to be misaligned with the swinging tooth before the two supporting rods are rotated rearward to drive the pushing block to rotate about the rivet to correspond to an upper end of the arc-shaped position-providing groov
