Pull-out table with single slide rail

Abstract

A pull-out table with a single slide rail including a table frame, first and second table boards symmetrically disposed on the table frame, an extended table board disposed between the first and second table boards, and a sliding rail assembly, is provided. The sliding rail assembly including rope winding wheels is disposed on an inner frame on one side of the table frame along a length of the table frame. The rope winding wheel on one end of the inner frame is cooperatively linked to the rope winding wheel on the other end of the inner frame through a synchronously wound steel rope. The first and second table boards are respectively connected to an upper part and a lower part of the steel rope through respective slider seats. When one of the table boards is pulled, the other table board is driven to move in an opposite direction.

DETAILED DESCRIPTION OF THE INVENTION

(7) A pull-out table with a single slide rail of the present invention is further described below with reference to the drawings.

(8) As shown in FIG. 1 to FIG. 4, the pull-out table 100 with the single slide rail comprises a table frame 1, two sliding table boards 2 and 3, an extended table board 4, and a sliding rail assembly 7. The bottom of the table frame 1 is provided with table legs 9 as shown in FIG. 1 and FIG. 2. 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 sliding rail assembly 7 is disposed on an inner frame 1a on one side of the table frame 1 along a length of the table frame 1. The sliding rail assembly 7 comprises a rope winding wheel 72 disposed on each of the two ends of the inner frame 1a. The rope winding wheel 72 on one end 1c of the inner frame 1a shown in FIG. 4, is cooperatively linked to the rope winding wheel 72 on the other end of the inner frame 1a through a synchronously wound steel rope 71 as shown in FIG. 5. The steel rope 71 is connected to the first table board 2 or the second table board 3 through a slider seat 73. The slider seat 73 is disposed on a bottom surface 2a of the first table board 2 shown in FIG. 4, and to a bottom surface 3a of the second table board 3 as shown in FIG. 3. One slider seat 73 is fixed to the upper part 71a of the steel rope 71 and the other slider seat 73 is fixed to the lower part 71b of the steel rope 71 as shown in FIG. 5. The first table board 2 and the second table board 3 are respectively connected to the upper part 71a and the lower part 71b of the steel rope 71. The second table board 3 is driven to move in the opposite direction when the first table board 2 is pulled, or the first table board 2 is driven to move in the opposite direction when the second table board 3 is pulled. In an embodiment, the sliding rail assembly 7 further comprises a guide rail disposed on the inner frame 1a on the one side of the table frame 1. The slider seat 73 at the bottom of each of the first table board 2 and the second table board 3 is configured to move within the guide rail.

(9) The pull-out table 100 further comprises a chute 5 disposed on an inner frame 1b on the other side relative to the sliding rail assembly 7. That is, the chute 5 is disposed on the inner frame 1b on the other side of the table frame 1 opposite to the sliding rail assembly 7. The pull-out table 100 further comprises a slider 6 disposed on each of the bottom surfaces 2a and 3a of the first table board 2 and the second table board 3, respectively, as shown in FIG. 1 and FIG. 4. The slider 6 is configured to move back and forth to match movement of the sliding rail assembly 7 along the chute 5, to drive the first table board 2 and the second table board 3 to be joined or separated. As shown in FIG. 4, the pull-out table 100 further comprises a stopper 8 disposed on each of the two ends of the chute 5. The stopper 8 is configured to limit a stroke of the slider 6. When sliding in the chute 5, the slider 6 assists in linear sliding of the first table board 2 and the second table board 3, so that the cost and manufacturing difficulty are reduced and the pulling smoothness of the pull-out table 100 is improved.

(10) In an embodiment, the extended table board 4 is configured as a turnover table board comprising a first turnover table board 41 and a second turnover table board 42 as shown in FIG. 4. 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. 4. The first turnover table board 41 and the second turnover table board 42 are fixed to the table frame 1 through hinges 12. The hinges 12 are disposed on corresponding crosspieces 11 in the table frame 1 as shown in FIG. 4. The crosspieces 11 are arranged along a width of the table frame 1.

(11) As shown in FIG. 5, for a specific use, to expand the usable area of the 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 steel rope 71 drives the slider seat 73 to move in the opposite direction, and further drives the first table board 2 to be separated from 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, 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 steel rope 71 drives the slider seat 73 to move in the opposite direction until the first table board 2 and the second table board 3 are joined.

(12) 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 pull-out table 100.

(13) When cost is not a concern, the sliding rail assembly 7 can be arranged on the two inner frames 1a and 1b of the table frame 1 along the length of the table frame 1, without the chute 5 and the slider 6.

(14) 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.
