DETAILED DESCRIPTION OF THE INVENTION

(15) To facilitate understanding of the purpose, characteristics and effects of the present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided as below.

(16) Referring to FIG. 1, FIG. 1 is a preferable embodiment of a folding table of the present disclosure, the folding table includes a table frame 1, a table plate 2 and at least one gravity lock 3, the table plate 2 is detachably disposed at the table frame 1, and the gravity lock 3 is disposed at the table frame 1.

(17) In detail, the table frame 1 has a first crossbar 11a and a second crossbar 11b spaced apart in a Y direction in an unfolded state, the first crossbar 11a and the second crossbar 11b can each extend along a X direction, and the first crossbar 11a and the second crossbar 11b each have a folding portion 111. Two first side stands 12a are respectively pivoted to first ends of the first crossbar 11a and the second crossbar 11b, and two second side stands 12b are respectively pivoted to second ends of the first crossbar 11a and the second crossbar 11b; the two first side stands 12a and the two second side stands 12b can each extend along a Z direction. The table frame 1 also has a first side support set 13a and a second side support set 13b spaced apart in the X direction, and the first side support set 13a is respectively pivoted to the two first side stands 12a by two upper junctions 131 and two lower junctions 132; the second side support set 13b is respectively pivoted to the two second side stands 12b by two upper junctions 131 and two lower junctions 132.

(18) The table plate 2 is detachably mounted on the first crossbar 11a and the second crossbar 11b, and covers a space between the first crossbar 11a and the second crossbar 11b. The gravity lock 3 is disposed at the folding portion 111 of the first crossbar 11a and/or the folding portion 111 of the second crossbar 11b, so that the first crossbar 11a and the second crossbar 11b are controlled not to be folded when locked, but can be folded when unlocked.

(19) Referring to FIG. 2 to FIG. 5, the gravity lock 3 has a body 31, a lock lever 32 and two side sheets 33. The body 31 is provided with two longitudinal long grooves 311 spaced apart in the Y direction, and the two longitudinal long grooves 311 each extend along the Z direction. The lock lever 32 is penetratingly disposed in the two longitudinal long grooves 311, and two ends of the lock lever 32 respectively penetrate and extend out of the corresponding longitudinal long grooves 311. The two side sheets 33 are respectively located at two sides of the body 31 in the Y direction, one end of the two side sheets 33 is combined with the first crossbar 11a or the second crossbar 11b, and the other end is pivoted to the body 31 by a pivot portion 331. The two side sheets 33 are each provided with a slot 332, and a first end 332a of the slot 332 is closer to the pivot portion 331 than a second end 332b; the two side sheets 33 each have a hook portion 333 extending from the first end 332a to the second end 332b of the slot 332, so as to shade a partial opening of the slot 332 by the hook portion 333.

(20) The gravity lock 3 is in the locked state as shown in FIG. 4, the slots 332 of the two side sheets 33 are respectively aligned with the two longitudinal long grooves 311 of the body 31, and the two ends of the lock lever 32 can respectively penetrate the slots 332 of the two side sheets 33; at this time, the lock lever 32 is located at the first end 332a of the slot 332 by gravity, and is located within the scope of the hook portion 333, so that the lock lever 32 is clamped by the hook portion 333, and the two side sheets 33 are limited from pivoting relative to the body 31.

(21) The gravity lock 3 can be inverted to switch the gravity lock 3 to the unlocked state as shown in FIG. 5. That is, at this time, the lock lever 32 can be affected by gravity and fall towards the second end 332b of the slot 332, thereby detaching from the scope of the hook portion 333, so that the two side sheets 33 can pivot relative to the body 31.

(22) Referring to FIG. 1 and FIG. 2, in the unfolded state of the folding table, because the two side sheets 33 of the gravity lock 3 are facing downwards with the first end 332a of the slot 332, the gravity lock 3 can automatically appear locked, so that the folding parts 111 of the first crossbar 11a and the second crossbar 11b are limited by the gravity lock 3 and cannot be folded, and the unfold state can be remained in a straight line, so that the situation that the folding table is accidentally deformed in use can be avoided.

(23) Referring to FIG. 1, FIG. 6 and FIG. 7, to fold the folding table, the table plate 2 may be detached from the first crossbar 11a and the second crossbar 11b. Then, as shown in FIG. 6, the first side support set 13a and the second side support set 13b are folded, so that the first crossbar 11a and the second crossbar 11b can be brought together to form the state shown in FIG. 7, and the volume of the folding table in the Y direction is reduced. At this time, the gravity lock 3 remains in the locked state.

(24) Referring to FIG. 8, continuously, the folding table is inverted, the first crossbar 11a and the second crossbar 11b are placed on the ground, and the two first side stands 12a and the two second side stands 12b are facing upwards. At this time, referring to FIG. 5 together, the gravity lock 3 can be automatically switched to the unlocked state because of inversion.

(25) Referring to FIG. 9, continuously, the second first side post 12a and the two second side stands 12b are folded inward to reduce the volume of the folding table in the Z direction.

(26) Referring to FIG. 5 and FIG. 10, because the gravity lock 3 has been switched to the unlocked state, the first crossbar 11a and the second crossbar 11b can be folded successively according to their respective folding portions 111, so as to reduce the volume of the folding table in the X direction, so that the table frame 1 can be converted into a folded state as shown in FIG. 11.

(27) Conversely, to switch the table frame 1 from the folded state back to the unfolded state, the user only needs to reverse the preceding steps. Among them, when the table frame 1 changes to the state shown in FIG. 7, the gravity lock 3 can automatically switch back to the locked state.

(28) Therefore, regarding the folding table of the present embodiment, in the process of switching the table frame 1 from the unfolded state to the folded state, it has undergone a volume reduction of three dimensions, so that the volume of the overall table frame 1 can be greatly reduced, so that it can be easily placed in a narrow space (such as the rear compartment of a car), and the convenience of storage or movement is improved, so it is very suitable for being used in the occasion that the table needs to be carried frequently and used outdoors. In addition, in the process of switching to the unfolded or folded state of the table frame 1, the gravity lock 3 can be automatically locked or unlocked, so that it can further improve the convenience and efficiency of operation, as well as the safety of use.

The body 31 has an intermediate sheet 31a connecting two opposite sheets 31b, and the two opposite sheets 31b can be opposite in the Y direction, so that the cross-section of the lower half of the body 31 on the XY plane may be approximately U-shaped, and the two longitudinal long grooves 311 may be respectively disposed at the two opposite sheets 31b. In the locked state of the gravity lock 3, the clamping plates 33a of the two side sheets 33 can be respectively located at the opposite outer sides of the two opposite sheets 31b, and the slots 332 of the two side sheets 33 can be respectively aligned at the two longitudinal long grooves 311, and the inclined portions 334 of the two side sheets 33 can be aligned at rear end faces 312 of the adjacent opposite sheets 31b. In this way, the gravity lock 3 of the present embodiment can be firmly combined to the two sides of the first crossbar 11a or the second crossbar 11b by the two side sheets 33 and the two opposite sheets 31b of the body 31 respectively, and has the effect of improving the convenience of assembly.
