Chinese patent application number 202020221384.0 and Chinese patent application number 202022199246.X are incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to a folding table.

BACKGROUND OF THE DISCLOSURE

Existing folding tables mainly comprise a table board and a pair of X-shaped cross legs. The table board is hinged on the X-shaped cross legs. The X-shaped cross legs are folded while the table board is turned over. Although the structure of folding tables with X-shaped cross legs is very simple, the table board is simply and rotatably connected to the X-shaped cross legs without any positioning, which enables the folding table to be unfolded and folded at will, and the structure is very weak.

In order to enhance the stability of the folding table, people have added a support frame between the table board and table legs. The table board and the table legs are respectively and rotatably connected to the support frame. The table board and the support frame, as well as the table legs and the support frame, are connected by support poles. This structure relies on the support poles, which are usually diagonally situated, to maintain a structural stability of the table when the table is in an unfolded state, which greatly improves a rigidity of the folding table. However, there are multiple, diagonally situated support poles arranged under the table board. The diagonally situated support poles limit a utilization rate of space under the table board. The space able to receive feet under the folding table is reduced, the comfort of people sitting at the folding table is not very good, and usage of the folding table is inconvenient. In addition, in order to further improve the stability of the folding table when the folding table is unfolded, some folding tables also have a locking mechanism between the table board and the support frame. For example, an elastic buckle on the support frame snaps into a locking hole of the table board. When the locking mechanism is unlocked, the elastic buckle needs to be forced opened. Fingers of a user can be easily pinched, and the operation is very inconvenient.

BRIEF SUMMARY OF THE DISCLOSURE

The present disclosure provides a folding table. The folding structure of the folding table is firm and simple, and the folding structure is convenient to use.

In order to solve the technical problems, a technical solution of the present disclosure is as follows.

A folding table comprises a table board, a support leg, and a bracket connected between the table board and the support leg. A top portion of the bracket is disposed with an upper crossbar, the upper crossbar is positioned on a rear portion of a bottom surface of the table board, the table board is configured to rotate about the upper crossbar, a bottom portion of the table board is disposed with one or more pawls, the upper crossbar is disposed with one or more lock plates, edges of the one or more lock plates comprise at least one ratchet wheel groove. When the one or more pawls are disposed in the at least one ratchet wheel groove, the table board is configured to rotate upward. When the folding table is in a folded state, the one or more pawls are separated from the at least one ratchet wheel groove, and the table board rotates downward to be vertically disposed. When the folding table is in an unfolded state, the table board rotates upward. When the one or more pawls are disposed in the at least one ratchet wheel groove, the table board is locked to prevent the table board from rotating downward. When the table board needs to be folded, the table board firstly rotates upward to enable the one or more pawls to be separated from the at least one ratchet wheel groove, and the table board then rotates downward to be folded.

Compared with the existing techniques, the technical solution has the following advantages.

The top of the bracket is disposed with an upper crossbar to rotatably connect with the table board, so that the table board can be rotated around the upper crossbar to realize folding and unfolding. Moreover, the bottom of the table board is disposed with pawl, and the upper crossbar is equipped with ratchet wheel grooves. The pawl and the ratchet wheel groove define a ratchet and pawl mechanism to limit the position of the table board. The table board cannot be turned down when in use, and the table board can bear weight well. The structure is firm, and the structure under the table board is simple. When the table board needs to be folded, the table board can be turned upward to separate the pawl from the ratchet wheel groove to realize unlocking. After unlocking, the table board can be turned down to a folded state, which is very convenient to operate

DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiment 1

Referring to FIGS. 1-9, a folding table comprises a table board 10, a support leg 20, and a bracket 30 connected between the table board 10 and the support leg 20. The table board 10 is configured to be folded or unfolded for use using a folding structure.

A top portion of the bracket 30 is disposed with an upper crossbar 32, and the upper crossbar 32 is positioned on a rear portion of a bottom surface of the table board 10. The table board 10 is configured to rotate (i.e., rotates 90 degrees) about the upper crossbar 32. A bottom portion of the table board 10 is disposed with one or more pawls 40. The upper crossbar 32 is disposed with one or more lock plates 321. Edges of the one or more lock plates 321 comprise at least one ratchet wheel groove 322, and the one or more pawls 40 and the at least one ratchet wheel groove 322 define one or more ratchet and pawl mechanisms. That is, when the one or more pawls 40 are snapped to the ratchet wheel groove 322, the table board 10 is restricted to rotate in a single direction (i.e., rotate 90 degrees in a single direction). In this embodiment, the table board 10 is configured to rotate upward when the one or more pawls 40 are disposed in the at least one ratchet wheel groove 322.

In a folded state (as shown in FIG. 4), the one or more pawls 40 are separated from the at least one ratchet wheel groove 322, and the table board 10 rotates downward to be vertically disposed. In an unfolded state (i.e., a use state) (as shown in FIGS. 5 to 7), the table board 10 rotates upward, when the one or more pawls 40 are disposed in the at least one ratchet wheel groove 322, and the table board 10 is locked to prevent the table board 10 from rotating downward. When the table board 10 needs to be folded, the table board 10 firstly rotates upward to enable the one or more pawls 40 to be separated from the at least one ratchet wheel groove 322 (as shown in FIG. 8). That is, the table board 10 is firstly unlocked, and then the table board 10 rotates downward again to be folded and returns to the state shown in FIG. 4.

The one or more pawls 40 of the table board 10 and the at least one ratchet wheel groove 322 of the bracket 30 define the one or more ratchet and pawl mechanisms to position the table board 10 during use in the unfolded state, and the table board 10 only needs to rotate upward to release the positioning to fold the table board 10. The operation is very convenient. In some embodiments, the one or more lock plates 321 are fan-shaped plate structures, and the one or more pawls 40 are disposed in the at least one ratchet wheel groove 322 to limit a rotation direction of the table board 10. Mating relationships between the one or more pawls 40 and the at least one ratchet wheel groove 322 are conventional and will not be described further herein.

In some embodiments, the folding table further comprises one or more snapping torsion springs 50, and the one or more snapping torsion springs 50 apply upward elastic forces to the one or more pawls 40 to enable the one or more pawls 40 to be fastened to the at least one ratchet wheel groove 322. In this way, when the one or more pawls 40 rotate with the table board 10 to align with the at least one ratchet wheel groove 322, the one or more pawls 40 are completely automatically fastened to the at least one ratchet wheel groove 322 without manual intervention. The operation is therefore more convenient.

In some embodiments, one or more mounting bases 60 are disposed on a lower side (i.e., the bottom surface) of the table board 10, and the one or more mounting bases 60 are locked to the lower side of the table board 10 by screws. The one or more pawls 40 are disposed on the one or more mounting bases 60, first ends of the one or more snapping torsion springs 50 are tensioned to abut the one or more mounting bases 60, and second ends of the one or more snapping torsion springs 50 are secured to the one or more pawls 40. The one or more pawls 40 are disposed on the one or more mounting bases 60, so that an internal structure of the table board 10 will not be occupied. The internal structure of the table board 10 does not need to be changed, and the table board 10 can be made to be thin.

In some embodiments, each of the edges of the one or more lock plates 321 comprise a plurality of ratchet wheel grooves 322 disposed along an arc track at intervals. Referring to FIG. 5, the one or more pawls 40 are separated from the plurality of ratchet wheel grooves 322, and the one or more snapping torsion springs 50 are in released states. Referring to FIGS. 6 and 7, when the table board 10 rotates upward, the one or more pawls 40 are disposed in one ratchet wheel groove of the plurality of ratchet wheel grooves 322, and the one or more snapping torsion springs 50 are pressed to sides of the one or more mounting bases 60. Referring to FIGS. 8 and 9, after the one or more pawls 40 slide over one or more uppermost ratchet wheel grooves 322 of the plurality of ratchet wheel grooves 322, the upward elastic forces of the one or more snapping torsion springs 50 are released to drive the one or more pawls 40 to rotate upward, so that arc end surfaces of the one or more pawls 40 face the plurality of ratchet wheel grooves 322 and the one or more pawls 40 are separated from the plurality of ratchet wheel grooves 322. The table board 10 is configured to rotate downward. When the table board 10 rotates downward to be vertically disposed (i.e., rotated downward to the folded state), the one or more pawls 40 are separated from one or more lowermost ratchet wheel grooves 322 of the plurality of ratchet wheel grooves 322. Since the number of ratchet wheel grooves 322 is multiple, when the one or more pawls 40 are engaged with different ratchet wheel grooves 322, an opening angle of the table board 10 is different, so that a work angle of the table board 10 can be adjusted. In some embodiments, the table board 10 is in a horizontal state when the one or more pawls 40 are disposed in the one or more uppermost ratchet wheel grooves 322 (as shown in FIG. 7).

In some embodiments, the folding table further comprises one or more reset torsion springs 80, and the one or more reset torsion springs 80 apply elastic forces to the table board 10 to enable the table board 10 to have a tendency to rotate downward (e.g., to the folded state). After the table board 10 rotates upward (e.g., to the unfolded state), the one or more pawls 40 slide over the uppermost ratchet wheel groove 322 (as shown in FIG. 8), the user releases two hands, and the table board 10 automatically rotates downward to be folded due to the one or more reset torsion springs 80, so that the table board 10 can be automatically folded.
