The table boards 20 and the bench boards 30 are horizontally positioned when disposed in an unfolded state.

(15) The frame 10 comprises two supporting rods 12 vertically disposed side by side and back and forth, and two sides of the table boards 20 are respectively and pivotally connected to top portions of the two supporting rods 12. The frame 10 is disposed with a pair of crossbars 14 corresponding to each of the table boards 20. The crossbars 14 corresponding to each of the table boards 20 are respectively and rotatably connected to the top portions of the two supporting rods 12, and the crossbars 14 are configured to rotate in a horizontal plane. The crossbars 14 support lower sides of the table boards 20 to enable the table boards 20 to be maintained in a horizontal position.

(16) The frame 10 is disposed with a pair of link rod mechanisms 16 corresponding to each of the bench boards 30, and the link rod mechanisms 16 corresponding to each of the bench boards 30 are respectively connected to bottom portions of the two supporting rods 12 configured to support the bench boards 30. The link rod mechanisms 16 comprise swing arms 162 and connecting arms 164 rotatably connected together. The swing arms 162 are supported on the ground, and the connecting arms 164 are configured to rotate toward the swing arms 162 to abut upper sides of the swing arms 162. Outer ends of the swing arms 162 are rotatably connected to the connecting arms 164, and inner ends of the swing arms 162 are pivotally connected to the two supporting rods 12 to rotate toward an inner side of the frame 10 in a horizontal plane. Outer ends of the connecting arms 164 are disposed with connecting shafts 166. The connecting shafts 166 are configured to support bottom portions of the bench boards 30, and the connecting shafts 166 are disposed along width directions of the bench boards 30 and are rotatably connected to the bench boards 30. The link rod mechanisms 16 support lower sides of the bench boards 30, and the bench boards 30 are maintained in the horizontal position.

(17) Referring to FIGS. 3 and 4, in a folded state, the crossbars 14 rotate toward the inner side of the frame 10 to abut inner sides of the table boards 20, and the table boards 20 are configured to rotate downward to be vertically positioned.

(18) Referring to FIGS. 5 and 6, in the folded state, the connecting arms 164 and a first bench board 30 rotate toward the side of the supporting rod 12 to switch the first bench board 30 to a vertical position. The connecting shaft 166 is also switched to the vertical position, and the swing arm 162 and the connecting arm 164 can rotate toward the inner side of the first bench board 30 and together lean against a bottom of the bench board 30.

(19) Referring to FIG. 7, a second table board 20 and a second bench board 30 are folded in the same way.

(20) In some embodiments, in the folded state, a rotation axis between the swing arm 162 and the supporting rod 12 is aligned with the connecting shaft 166, so that the swing arm 162 and the connecting arm 164 rotate inward more smoothly. Further, the bottom portion of the supporting rod 12 is disposed with a C-shaped frame 122, and the inner end of the swing arm 162 is disposed in the C-shaped frame 122 to be rotatably connected to the C-shaped frame 122. In the folded state, the bench board 30 stands on the C-shaped frame 122 and abuts an outer side of the supporting rod 12. Therefore, the structure is more compact in the folded state.

(21) In some embodiments, the connecting arm 164 defines a C-shape with an opening toward the frame 10 to have better bearing capacity.

(22) Referring to FIGS. 5 and 6, in some embodiments, a middle portion of a bottom surface of the bench board 30 is longitudinally disposed with a reinforcing rod 32, and a connecting rod 40 is connected between the connecting arm 164 and the reinforcing rod 32. One end of the connecting rod 40 is pivotally connected to the connecting arm 164, the other end of the connecting rod 40 is pivotally connected to a sliding sleeve 50, and the sliding sleeve 50 is slidably disposed on the reinforcing rod 32. In the unfolded state, the connecting rod 40 is configured to provide a supporting force to a middle portion of the bench board 30 to enhance a bearing capacity of the bench board 30. In some embodiments, the reinforcing rod 32 comprises an insertion hole 52, and the sliding sleeve 50 is disposed with a movable pin 51. In the unfolded state, the movable pin 51 is disposed in the insertion hole 52.

(23) Referring to FIGS. 2 and 3, in some embodiments, an outer end of the crossbar 14 comprises a convex point 142, and the bottom surface of the table board 20 is disposed with a snapping block 22 corresponding to the crossbar 14. The snapping block 22 is disposed with a sliding groove 221 defining an arc-shape corresponding to the convex point 142, and an end of the sliding groove 221 defines a positioning hole 222. In the unfolded state, the convex point 142 is maintained in the positioning hole 222. When the convex point 142 and the sliding groove 221 begin to relatively slide, a frictional force is needed to ensure that the convex point 142 is better maintained in the positioning hole 222. The crossbar 14 is driven to rotate only under an external force. Further, a handle 144 is disposed on an outer end of the crossbar 14.

(24) In some embodiments, left sides and right sides of top ends of the two supporting rods 12 are respectively disposed with connecting pieces 124, and the connecting pieces 124 are pivotally connected to the table boards 20. Sides of the table boards 20 are disposed with baffles 24 configured to cover the connecting pieces 124 from outer sides. The frame 10 further comprises a fixed rod 18 connected between the two supporting rods 12.

(25) It is understandable that with respect to the foldable table bench of the present disclosure, the table boards 20 disposed on the left side and the right side are independent, and the bench boards 30 disposed on the left side and the right side also are independent. Therefore, the foldable table bench can also be designed into a structure comprising a single table board and a single bench board. That is, a table board 20 and a bench board 30 are merely disposed on a single side of the frame 10, which also has a foldable function, as illustrated in Embodiment 2 shown in FIG. 8.

(26) Referring to FIG. 9, a foldable table bench of Embodiment 3 of the present disclosure is illustrated. This embodiment differs from Embodiment 1 in that the table boards 20 are not pivotally connected to the two supporting rods 12 of the frame 10, and the frame 10 is further disposed with a middle board 19. The middle board 19 is horizontally disposed back and forth and is connected to the top portions of the two supporting rods 12. Two sides of the table boards 20 are pivotally connected to the middle board 19, and the table boards 20 are configured to rotate relative to the middle board 19. In the unfolded state, the table boards 20 are horizontally disposed in a plane disposed with the middle board 19, and the middle board 19 is positioned between the table boards 20. In the folded state, the table boards 20 rotate downward to be vertically positioned. The middle board 19 is disposed between the table boards 20, and the middle board 19 is configured to fill a gap between the table boards 20 and prevent fingers from being inserted between the table boards 20 that might result in safety accidents. Similarly, the frame 10 is further disposed with the crossbars 14 to support the table boards 20. In the folded state, the crossbars 14 rotate to be stored under the middle board 19, and the table boards 20 rotate downward to be vertically positioned.

(27) Referring to FIGS. 10 and 11, a foldable table bench of Embodiment 4 of the present disclosure differs from Embodiment 1 in that the two sides of the bottom portion of the table board 20 (i.e., the first table board 20 or the second table board 20 of the pair of table boards 20) are disposed with two guide rods 26 corresponding to the two supporting rods 12. The two guide rods 26 are disposed with sliding bases 262, and the sliding bases 262 are configured to slide along the two guide rods 26. The two guide rods 26 comprise lock holes 261, and the sliding bases 262 are disposed with movable pins 263. The movable pins 263 are disposed in the lock holes 261 to enable positions of the sliding bases 262 to be limited and to enable the table board 20 to be maintained in a horizontal state. When the table board 20 needs to be folded, the movable pins are configured to be separated from the lock holes. That is, the movable pins of the two guide rods 26 disposed on the two sides are operated by two hands from a lower side of the table board 20. Bearing rods 27 are disposed between the sliding bases 262 and the two supporting rods 12, and two ends of the bearing rods 27 are pivotally and respectively connected to the sliding bases 262 and the two supporting rods 12. In the unfolded state, the movable pins are disposed in the lock holes, the bearing rods 27 support the lower side of the table board 20 to enable the table board 20 be maintained in the horizontal position. In the folded state, the movable pins are pulled out from the lock holes, and the table board 20 is configured to rotate downward to be vertically positioned. Top surfaces of the bench boards 30 comprise space-giving grooves 34 corresponding to the two supporting rods 12. In the folded state, the space-giving grooves 34 are buckled on the two supporting rods 12. Middle portions of inner sides of top surfaces of the table boards 20 comprise handle grooves 28 to facilitate the foldable table bench being lifted.

(28) Referring to FIG. 12, a foldable table bench of Embodiment 5 of the present disclosure differs from Embodiment 4 in that a pull rod 29 is connected between the two guide rods 26 disposed below the table board 20. Two ends of the pull rod 29 are respectively rotatably connected to the two guide rods 26, and the pull rod 29 is operatively connected to the movable pins of two sliding bases 262. That is, the pull rod 29 rotates to enable buttons disposed on the two sliding bases 262 to be simultaneously pressed to drive the movable pins of the two sliding bases 262 to be pulled out from the lock holes, and it is more convenient to fold the table board 20.

(29) The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
