DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to FIGS. 1 to 7, this embodiment provides a cabinet 10, which includes a cabinet body 20, a door panel 30, and an opening and closing mechanism 40.

[0020] A slide rail 21 and a first pivoting portion 22 are disposed within the cabinet body 20.

[0021] The door panel 30 has a sliding portion 31 and a second pivoting portion 32, and the sliding portion 31 is rotatably and slidably connected to the slide rail 21.

[0022] The opening and closing mechanism 40 includes a linkage member 41, which has a third pivoting portion 411 pivotally connected to the first pivoting portion 22 and a fourth pivoting portion 412 pivotally connected to the second pivoting portion 32.

[0023] One side of the cabinet body 20 along a horizontal direction is provided with an opening 23. The slide rail 21 extends linearly along the horizontal direction. The slide rail 21 has a front end 211 adjacent to the opening 23 and a rear end 212 away from the opening 23. The first pivoting portion 22 is disposed below the slide rail 21 along a vertical direction. The cabinet body 20 defines a virtual pivoting axis C passing through the first pivoting portion 22 and extending along the horizontal direction. The linkage member 41 is rotatable relative to the cabinet body 20 about the pivoting axis C. The door panel 30 has a top end 33 and a bottom end 34 opposite the top end 33. The sliding portion 31 is adjacent to the top end 33. The second pivoting portion 32 is disposed between the top end 33 and the bottom end 34. The door panel 30 is movable between a closed position and an open position. When the door panel 30 is in the closed position, the top end 33 is moved near the front end 211, and the bottom end 34 is moved near a lower edge of the opening 23 along the vertical direction, thereby closing the opening 23. When the door panel 30 is in the open position, the sliding portion 31 is moved near the rear end 212, and the bottom end 34 is moved near an upper edge of the opening 23 along the vertical direction, thereby not closing the opening 23.

[0024] A fifth pivoting portion 24 is disposed within the cabinet body 20. The linkage member 41 is provided with a sixth pivoting portion 413. The opening and closing mechanism 40 includes a damper 42. The damper 42 is provided with a seventh pivoting portion 421 and an eighth pivoting portion 422. The damper 42 is retractable to change a distance between the seventh pivoting portion 421 and the eighth pivoting portion 422. The seventh pivoting portion 421 is pivotally connected to the fifth pivoting portion 24. The eighth pivoting portion 422 is pivotally connected to the sixth pivoting portion 413.

[0025] The fifth pivoting portion 24 is disposed below the first pivoting portion 22 along the vertical direction. The opening and closing mechanism 40 defines a reference surface P parallel to the pivoting axis C and passing through the seventh pivoting portion 421 and the eighth pivoting portion 422. When the door panel 30 is in the closed position, the third pivoting portion 411 is located on a side of the reference surface P opposite to the opening 23, and the fourth pivoting portion 412 is located on the other side of the reference surface P adjacent to the opening 23. When the door panel 30 is in the open position, both the third pivoting portion 411 and the fourth pivoting portion 412 are located on the side of the reference surface P opposite to the opening 23.

[0026] The sliding portion 31 is provided with a shaft rod 311 and a circular sliding block 312. The sliding block 312 is sleeved around the shaft rod 311 and disposed within the slide rail 21.

[0027] The side of the cabinet body 20 along the horizontal direction is provided with a side plate 25 adjacent to the opening 23. The slide rail 21 is connected to an upper edge of the side plate 25 along the vertical direction. The first pivoting portion 22 is disposed on the side plate 25.

[0028] The cabinet 10, through the aforementioned structure, allows the user to easily lift or close the door panel 30. To lift the door panel 30, the user only needs to pull the bottom end 34 outward in an upward-slanting direction. This action not only lifts the door panel 30 but also, through the linkage of the opening and closing mechanism 40, enables the door panel 30 to be horizontally inserted into the cabinet body 20. Conversely, to close the door panel 30, the user simply pulls the bottom end 34 outward in a downward-slanting direction. This action not only draws the door panel 30 out of the cabinet body 20 but also, through the linkage of the opening and closing mechanism 40, allows the door panel 30 to vertically close the opening 23.

[0029] Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
