DETAILED DESCRIPTION OF THE INVENTION

[0017] A gear type pull-out table 100 of the present invention is further described below with reference to the drawings.

[0018] As shown in FIG. 1 and FIG. 2, the gear type pull-out table 100 comprises a table frame 1, two sliding table boards 2 and 3, an extended table board 4, and a gear assembly 5. The bottom of the table frame 1 is provided with table legs 9. The extended table board 4 is disposed between the two sliding table boards 2 and 3. The sliding table boards comprise a first table board 2 and a second table board 3. The first table board 2 and the second table board 3 are symmetrically disposed on the table frame 1. The gear assembly 5 is positioned in the table frame 1, corresponding to the extended table board 4. The gear assembly 5 is disposed on one side 1b of the table frame 1 along the length direction as shown in FIG. 2. The gear assembly 5 comprises a first toothed rack 51, a second toothed rack 52, and a gear 53 as shown in FIGS. 2-3. The first toothed rack 51 is fixed to the first table board 2. The second toothed rack 52 is fixed to the second table board 3. The gear 53 is in synchronous engagement with the first toothed rack 51 and the second toothed rack 52. The first toothed rack 51 and the second toothed rack 52 are disposed parallel to each other on two sides 53a and 53b of the gear 53, respectively, as shown in FIG. 3. The first table board 2 and the second table board 3 are driven to move in opposite directions through the synchronous engagement of the first toothed rack 51, the second toothed rack 52, and the gear 53 to join or separate the first table board 2 and the second table board 3.

[0019] The gear assembly 5 is fixed to an inner frame 1a of the table frame 1 shown in FIG. 1, using a connecting piece 7 as shown in FIG. 3. In an embodiment, one side 1b of the inner frame 1a with the gear assembly 5 is provided with a chute 11. The chute 11 is disposed on one side 1b of the table frame 1, proximal to the gear assembly 5. In an embodiment, the gear type pull-out table 100 further comprises a slider 8 disposed on a bottom surface, for example, 3a, of each of the first table board 2 and the second table board 3. The slider 8 is configured to move back and forth along the chute 11 to match the movement of the gear assembly 5, thereby driving the first table board 2 and the second table board 3 to be joined or separated.

[0020] When sliding in the chute 11, the slider 8 assists in linear sliding of the first table board 2 and the second table board 3, so that the cost and manufacture difficulty are reduced and the pulling smoothness of the gear type pull-out table 100 is improved.

[0021] In an embodiment, the extended table board 4 is a turnover table board comprising a first turnover table board 41 and a second turnover table board 42 as shown in FIG. 2. The first turnover table board 41 and the second turnover table board 42 are hinged in the middle. That is, the first turnover table board 41 is connected to the second turnover table board 42 via a central hinge 43 as shown in FIG. 2. The first turnover table board 41 and the second turnover table board 42 are fixed to the table frame 1 through a bearing seat 6 or a hinge.

[0022] For a specific use, to expand the usable area of the gear type pull-out table 100, a user can pull the first table board 2 and/or the second table board 3. When the user pulls the first table board 2 and/or the second table board 3, the gear 53 drives the first toothed rack 51 and the second toothed rack 52 to move in opposite directions, thereby separating the first table board 2 and the second table board 3, so that the extended table board 4 can be rotated to a position between the first table board 2 and the second table board 3 from below the table frame 1. The user can then fasten the first table board 2, the extended table board 4, and the second table board 3 mutually together using fasteners. To reduce the usable area of the gear type pull-out table 100, the user can rotate the extended table board 4 to make the extended table board 4 sink below the table frame 1, and can then push the first table board 2 and/or the second table board 3. When the user pushes the first table board 2 and/or the second table board 3, the gear 53 drives the first toothed rack 51 and the second toothed rack 52 to move in opposite directions until the first table board 2 and the second table board 3 are joined.

[0023] The present invention allows the user to conveniently adjust the usable area of the gear type pull-out table 100. The present invention precludes the need to remove the extended table board 4 from the table frame 1 or place another extended table board 4 in the table frame 1, which is convenient when there is a need to expand the usable area of the gear type pull-out table 100.

[0024] It shall be noted that the above embodiments have been provided only for illustrating the technical scheme of the present invention and not to limit the present invention. Although the present invention has been described with reference to the above embodiments, those ordinarily skilled in the art should understand that they can still modify the technical scheme recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; however, such modifications or replacements do not separate the essence of technical schemes from the substance and scope of the technical schemes provided by the embodiments of the present invention.
