In the present embodiment, the first furniture part 22 is a cabinet, and the second furniture part 24 is a drawer. FIG. 1 shows that the furniture system 20 comprises three drawers, but the quantity of the drawer is not limited in the present invention.

(16) As shown in FIG. 2, the furniture system 20 further comprises a slide rail assembly 21 having a first rail 26 and a second rail 28 longitudinally movable relative to the first rail 26. Preferably, the slide rail assembly 21 further comprises a third rail 30 movably mounted between the first rail 26 and the second rail 28 for extending a longitudinal traveling distance of the second rail 28 relative to the first rail 26. Wherein, the second furniture part 24 comprises a bottom wall 32, a side wall 34, a front panel 36 and a rear wall 38 for defining a drawer space. Wherein, the second rail 28 is configured to carry the second furniture part 24. In the present embodiment, the side wall 34 of the second furniture part 24 can be mounted to the second rail 28 in advance, and the front panel 36 of the second furniture part 24 is detachably fixed to a front end part of the side wall 34. On the other hand, the first rail 26 is fixed to the first furniture part 22. According to such arrangement, the second furniture part 24 is movable relative to the first rail 26 (or the first furniture part 22) through the second rail 28. Such configuration is well known to those skilled in the art, for simplification, no further illustration is provided.

(17) As shown in FIG. 3 and FIG. 4, the slide rail assembly 21 further comprises a blocking structure 40 arranged on one of the first rail 26 (fixed member) and the second rail 28 (movable member). In the present embodiment, the blocking structure 40 is arranged on the first rail 26, but the present invention is not limited thereto. When the blocking structure 40 is configured to be arranged on the fixed member of the furniture system 20, the blocking structure 40 can be arranged on one of the first rail 26 and the first furniture part 22. Preferably, the blocking structure 40 is fixed to the first rail 26, and the blocking structure 40 comprises a base 42 and a blocking member 44. The base 42 has a connecting part 42a, a vertical part 42b, a first bending part 42c and a second bending part 42d. Wherein, the connecting part 42a is fixedly connected to a bottom part of the first rail 26 and laterally extended from the bottom part of the first rail 26. The vertical part 42b is substantially perpendicularly connected to the connecting part 42a. The first bending part 42c is connected between the vertical part 42b and the second bending part 42d. Wherein, a room 46 is defined by the vertical part 42b, the first bending part 42c and the second bending part 42d; and the blocking member 44 is accommodated in the room 46. In the present embodiment, the blocking member 44 is fixed to the base 42 by engaging, and the blocking member 44 is partially exposed outside the room 46.

(18) Furthermore, the slide rail assembly 21 further comprises an adjusting device 48 arranged on the other one of the first rail 26 (fixed member) and the second rail 28 (movable member). In the present embodiment, the adjusting device 48 is arranged on a lateral side of the second rail 28 between a front part 28a and a rear part 28b of the second rail 28, but the present invention is not limited thereto. When the adjusting device 48 is configured to be arranged on the movable member of the furniture system 40, the adjusting device 48 can be arranged one of the second rail 28 and the second furniture part 24. The adjusting device 48 comprises an adjusting member 50, a working member 52 and a fixing frame 54.

(19) As shown in FIG. 4, FIG. 5 and FIG. 6, the fixing frame 54 comprises a first wall 56 and a second wall 58. Preferably, a middle wall 60 is arranged between the first wall 56 and the second wall 58. The first wall 56 and the second wall 58 are substantially perpendicularly connected to the middle wall 60. Wherein, the middle wall 60 is fixed to the second rail 28. For example, the middle wall 60 can be fixed to the second rail 28 by screwing, riveting, engaging or welding (please refer to FIG. 4). On the other hand, when the adjusting device 48 is configured to be arranged on the fixed member of the furniture system 20, the middle wall 60 can be fixed to the first rail 26 or the first furniture part 22. As shown in FIG. 4a, in other embodiments, the first wall 56 and the second wall 58 of the fixing frame can be integrated with the second rail 28 and arranged on the lateral side of the second rail 28. Therefore, the present invention is not limited thereto. On the other hand, when the adjusting device 48 is configured to be arranged on the fixed member of the furniture system 20, the first wall 56 and the second wall 58 of the fixing frame 54 can be integrated with the first rail 26 or the first furniture part 22.

(20) As shown in FIG. 5 and FIG. 6, a space S is defined between the first wall 56 and the second wall 58 of the fixing frame 54. The adjusting member 50 is accommodated in the space S. The adjusting member 50 has a first side L1 and a second side L2 opposite to the first side L1, and the first side L1 and the second side L2 respectively correspond to the first wall 56 and the second wall 58, such that the adjusting member 50 can be limited between the first wall 56 and the second wall 58. The first side L1 has a shaft part 62 pivoted to the first wall.

(21) The working member 52 comprises a screwing part 52a, a contact part 52b and a middle part 52c. The middle part 52c is connected between the screwing part 52a and the contact part 52b. The middle part 52c and the screwing part 52a of the working member 52 are configured to pass through a hole H of the second wall 58 and the second side L2 of the adjusting member 50 to be inserted into the adjusting member 50. The screwing part 52a is screwed to a Corresponding thread part 50a of the adjusting member 50. Wherein, the contact part 52b of the working member 52 is located outside the space S of the fixing frame 54. Therefore, the adjusting member 50 and the working member 52 are screwed to each other. Wherein, the working member 52 is located at an initial position P0 before the adjusting member 50 is rotated.

(22) As shown in FIG. 7 and FIG. 8, the adjusting device 48 is configured to convert a rotational movement of the adjusting member 50 into a linear movement of the working member 52 relative to the fixing frame 54 along a linear direction X. For example, when the adjusting member 50 is rotated along a first rotational direction R1, the working member 52 is linearly moved relative to the fixing frame 54 along a first direction D1 to a first position P1 in response to the rotation of the adjusting member 50. Moreover, the hole H of the second wall 58 allows the middle part 52c of the working member 52 to penetrate through. In the present embodiment, a contour of the middle part 52c is substantially identical to a shape of the hole H. Preferably, the hole H is a non-circular hole. In other words, the hole H and the middle part 52c have non-circular contours corresponding to each other.

(23) On the other hand, as shown in FIG. 9 and FIG. 10, when the adjusting member 50 is rotated along a second rotational direction R2, the working member 52 is linearly moved relative to the fixing frame 54 along a second direction D2 to a second position P2 in response to the rotation of the adjusting member 50. Wherein, the second rotational direction R2 is opposite to the first rotational direction R1, and the second direction D2 is opposite to the first direction D1.

(24) As shown in FIG. 11, the adjusting member 50 has not been rotated and the working member 52 is located at the initial position P0. In such state, when the second rail 28 (or the second furniture part 24) is retracted (such as completely retracted) relative to the first rail 26 (or the first furniture part 22), the working member 52 at the initial position P0 is configured to abut against the blocking structure 40. For example, the contact part 52b of the working member 52 abuts against the blocking member 44 of the blocking structure 40, such that the second rail 28 is located at an initial longitudinal position Y0 relative to the first rail 26. Meanwhile, an initial distance K0 is defined between the front part 28a of the second rail 28 and the blocking structure 40. On the other hand, an initial longitudinal distance Z0 is defined between the front panel 36 of the second furniture part 24 and the blocking structure 40.

(25) As shown in FIG. 12, the adjusting member 50 can be rotated along the first rotational direction R1, to drive the working member 52 to move to the first position P1. In such state, when the second rail 28 (or the second furniture part 24) is retracted (such as completely retracted) relative to the first rail 26 (or the first furniture part 22), the working member 52 at the first position P1 is configured to abut against the blocking structure 40. For example, the contact part 52b of the working member 52 abuts against the blocking member 44 of the blocking structure 40, such that the second rail 28 is located at a first longitudinal position Y1 relative to the first rail 26. Meanwhile, a first distance K1 is defined between the front part 28a of the second rail 28 and the blocking structure 40. On the other hand, a first longitudinal distance Z1 is defined between the front panel 36 of the second furniture part 24 and the blocking structure 40.

(26) As shown in FIG. 13, the adjusting member 50 can be rotated along the second rotational direction R2, to drive the working member 52 to move to the second position P2. In such state, when the second rail 28 (or the second furniture part 24) is retracted (such as completely retracted) relative to the first rail 26 (or the first furniture part 22), the working member 52 at the second position P2 is configured to abut against the blocking structure 40. For example, the contact part 52b of the working member 52 abuts against the blocking member 44 of the blocking structure 40, such that the second rail 28 is located at a second longitudinal position Y2 relative to the first rail 26. Meanwhile, a second distance K2 is defined between the front part 28a of the second rail 28 and the blocking structure 40. On the other hand, a second longitudinal distance Z2 is defined between the front panel 36 of the second furniture and the blocking structure 40. Wherein, the second longitudinal position Y2 is different from the first longitudinal position Y1, the second distance K2 is different from the first distance K1, and the second longitudinal distance Z2 is different from the first longitudinal distance Z1.

(27) Therefore, the furniture system and the slide rail assembly of the present invention are characterized in that:

(28) 1. Through adjusting the adjusting member 50, the position of the working member 52 along the linear direction X can be changed (the linear direction X is substantially identical to a longitudinal direction of the first rail 26 or the second rail 28, or a moving direction of the second rail 28 relative to the first rail 26), and the working member 52 is configured to abut against the blocking structure 40, such that the second rail 28 can be located at different longitudinal positions relative to the first rail 26 when the second rail 28 (or the second furniture part 24) is retracted (such as completely retracted) relative to the first rail 26 (or the first furniture part 22). As such, requirement of matching longitudinal depths (or lengths) or mounting tolerances for the first furniture part 22 and the second furniture part 24 can be satisfied.

(29) 2. Through arranging the adjusting device 48 and the blocking structure 40 respectively on the movable member and the fixed member of the furniture system, the movable member (such as the second rail 28 or the second furniture part 24) can be located at different longitudinal positions relative to the fixed member (such as the first rail 26 or the first furniture part 22) when the movable member is retracted. Therefore, structural arrangement of the present invention is simpler than that of the prior art, in order to meet specific operation requirements in the market.

(30) Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
