Abstract

A slide rail assembly includes a first rail, a second rail, a running carriage, a pushing member and an actuator member. The second rail is longitudinally movable relative to the first rail. The running carriage is movably mounted on the first rail and is used for carrying the second rail. When the second rail is moved, the running carriage is differentially movable relative to the second rail. The pushing member is movably connected to the first rail, and is movable between a horizontal position and an inclined position. The actuator member is connected to the second rail and corresponds to the pushing member while the pushing member is located at the horizontal position. When a differential movement error of the running carriage occurs, the actuator member is able to carry the pushing member and then the pushing member moves from the horizontal position to the inclined position to push the running carriage for correcting the error during the second rail moves from a retracted position to an extended position.

A more detailed understanding of the structure, features, functions and objects of the present invention is provided. The embodiments of the present invention are described in detail below with reference to the drawings.

1 shows a slide rail assembly 20 of an embodiment of the present invention applied to a cabinet 22 having a drawer 24. The drawer 24 can be captured into the cabinet 22 by the rail assembly 20 or pulled out of the cabinet 22.

2 shows a state in which the slide rail assembly 20 is extended and unfolded according to an embodiment of the present invention. The rail assembly 20 includes a first rail 26 that can be mounted to the cabinet 22, a second rail 30, and a third rail 32 by means of a mounting portion 28. The second rail 30 and the third rail 32 can be Vertically opposite The first rail 26 is displaced. The second rail 30 is movably mounted between the first rail 26 and the third rail 32; the third rail 32 is used to carry the drawer 24 described above. A differential correction mechanism 34 is coupled to the first rail 26. Here, the differential correction mechanism 34 is connected to the end portion adjacent to the first rail 26 as an example, but the implementation is not limited thereto. The differential correction mechanism 34 is coupled to the first rail 26 such that the differential correction mechanism 34 can be considered a portion of the first rail 26.

3 and 4 show the exploded state and the assembled state of the first rail 26, the second rail 30, and the third rail 32, respectively. A carriage 36 is slidably mounted to the first rail 26 and can carry the second rail 30. The carriage 36 includes at least one roller 38 (or ball) to carry the second rail 30 and assist in the active displacement of the second rail 30 relative to the first rail 26. In addition, the actuator 40 is coupled to the second rail 30. The actuating member 40 can be a protrusion or a rod, but is not limited thereto. When a deviation occurs between the differential displacement of the carriage 36 and the second rail 30, a portion of the differential correction mechanism 34 can be driven by the actuator 40 to enable the portion of the differential correction mechanism 34 to correct the portion. This deviation of the carriage 36 (described in detail later).

Figure 5 shows that the differential correction mechanism 34 includes a base 42 that can be attached (mounted) to the first rail 26 or integrally formed to the first rail 26; and a pusher 44 that is movably coupled to the base Base 42. Preferably, the base 42 includes a horizontal portion 46 (the direction of the horizontal portion 46 is the same as the longitudinal direction of the first rail 26), an inclined portion 48 is inclined at an angle relative to the horizontal portion 46, and a retaining wall 49. Located on the other side of the base 42 (on a different side than the horizontal portion 46). Preferably, the pushing member 44 includes at least one contact portion, wherein a first contact portion 50a and a second contact portion 50b are exemplified; a blocking portion 51 can be blocked by the retaining wall 49 of the base 42; And an arm portion 53 elastically connects the pusher 44.

As shown in FIG. 6A and FIG. 6B, when the pusher 44 is at a horizontal position (first position) P1 with respect to the base 42, the first contact portion 50a of the pusher 44 is in contact with the second contact portion 50b. a horizontal portion 46 of the base 42; when the pusher 44 is movably displaced from the horizontal position P1 to a tilted position (second position) P2 relative to the base 42, the first contact portion 50a of the pusher 44 is The second contact portion 50b is in contact with and is located at the horizontal portion 46 and the inclined portion 48 of the base 42 such that the pusher 44 is offset from the base 42 by an angle θ. In the inclined position P2, the pusher 44 is blocked by the retaining wall 49 of the base 42 by the blocking portion 51 to restrict the pusher 44 from being in the inclined position P2.

7A to 7C show that the pusher 44 is located at the inclined position P2 with respect to the base 42; and in a normal state, when the second rail 30 is shown (FIG. 7A to FIG. 7C only show the actuating member 40 to represent The movable position of the second rail 30 relative to the first rail 26 is longitudinally displaced relative to the first rail 26 from a retracting position toward a first direction D1 to an extended position, and the carriage 36 is followed by The active displacement of the second rail (the actuator 40) maintains a normal differential slip relative to the second rail (the actuator 40). For example, when the second rail (the actuating member 40) is moved to the first direction D1 by a stroke, the carriage 36 is synchronized and accurately follows the specificity of the second rail (the actuating member 40). Proportional stroke (for example, half of the trip). In addition, it is worth mentioning that when the pushing member 44 is located at the inclined position P2, the actuating member 40 does not correspond to a portion of the pushing member 44 (for example, the arm portion 53), so that the second rail is opposite to the first portion. The actuating member 40 is unable to drive the pusher 44 during the active displacement of the rail 26 from the collapsed position toward the extended position.

8A to 8C show that the pusher 44 is located at the inclined position P2 with respect to the base 42; and in a normal state, when the second rail 30 is shown (FIG. 8A to FIG. 8C only show the actuating member 40 to represent The movable position of the second rail 30 relative to the first rail 26 is longitudinally opposite to the folding direction of the first rail 26 from the extended position toward the second direction D2 to the retracting position, and the carriage 36 is opposite to the second rail. (The actuating member 40) maintains a normal differential displacement.

However, when the second rail (the actuating member 40) passes through the first rail 26 a plurality of times After the first direction D1 or the second direction D2 is moved back and forth, the sliding frame 36 is opposite to the second rail due to the sliding differential between the roller and the sliding rail or other external factors (the actuating member) 40) The specific ratio of differential displacement is not always guaranteed, so that an abnormal state of the differential displacement of the carriage 36 relative to the second rail (the actuator 40) may occur.

9A to 9D show that the pusher 44 is located at the inclined position P2 with respect to the base 42; and when an abnormal state occurs, a differential displacement of the carriage 36 relative to the second rail (the actuating member 40) is generated. The deviation causes a deviation of the position of the carriage 36 relative to the second rail (the actuator 40) during differential displacement, so that the carriage 36 cannot be opposite to the second rail according to a predetermined preset ratio (the actuation) 40) Active displacement. Therefore, in the biased state, when the second rail (the actuating member 40) is folded from the extended position to the second direction D2 relative to the first rail 26, the carriage 36 will touch the push. Piece 44 (Fig. 9C). When the second rail (the actuating member 40) is further folded toward the folded position relative to the first rail 26 toward the second direction D2, the pusher 44 is driven by the carriage 36 to make the pusher 44 The second contact portion 50b is disengaged from the inclined portion 48 of the base 42 to move the pusher 44 relative to the base 42 from the inclined position P2 to the horizontal position P1 (Fig. 9D).

10A to 10C show that the pusher 44 is at the horizontal position P1 with respect to the base 42, and the actuating member 40 is an arm portion 53 corresponding to the pusher 44 at the horizontal position P1. In detail, when the abnormal state is to be released, the displacement of the second rail (the actuating member 40) relative to the first rail 26 from the folded position toward the extended position in the first direction D1 may be The actuating member 40 can drive the pusher 44 by the arm portion 53 according to the corresponding relationship with the pusher 44, and the pusher 44 is movably displaced from the horizontal position P1 to the tilted position P2 with respect to the base 42. The carriage 36. Accordingly, the carriage 36 can be displaced by the pusher 44 to a predetermined position (for example, FIG. 10B) that can be normally differentially displaced relative to the second rail (the actuator 40), so that the sliding can be corrected. Frame 36 relative The deviation of the differential displacement of the two rails (the actuator 40). When the second rail (the actuating member 40) is further displaced relative to the first rail 26 in the first direction D1, since the pushing member 44 is already located at the inclined position P2, the actuating member 40 does not correspond to the The arm portion 53 of the pusher 44 is such that the actuating member 40 releases the pusher 44 at the inclined position P2 and cannot continue to drive the pusher 44. On the other hand, the carriage 36 can again maintain a normal differential displacement relative to the second rail (the actuator 40).

As shown in FIG. 11A and FIG. 11D, when the differential displacement of the carriage 36 is in a normal state, when the second rail 30 is shown (only the actuator 40 is shown in FIGS. 11A to 11D to indicate the second rail). 30 relative to the movable position of the first rail 26) relative to the first rail 26 from the collapsed position to the first direction D1, the carriage 36 is capable of opposing the second rail (the actuator 40) Maintain normal differential displacement. When the pusher 44 is at the horizontal position P1 relative to the base 42, the actuating member 40 drives the pusher 44 from the horizontal position P1 to the inclined position P2 during displacement, and due to the slide 36 has been normally differentially displaced with the second rail (the actuating member 40) by a distance in the first direction D1, so that the pusher 44 does not drive the carriage 36 at the tilted position P2 (ie, The differential displacement of the carriage 36 is not corrected by the pusher 44).

12A to 12C show that the pusher 44 is self-located relative to the base 42 at the horizontal position P1 due to external factors or unintentional factors. In this case, the second rail 30 can be used to indicate the active position of the second rail 30 relative to the first rail 26 by using only the actuator 40 in FIGS. 12A to 12C. When the extended position is displaced in the second direction D2, the arm portion 53 of the pusher 44 is pushed by the actuating member 40 to elastically bend the arm portion 53 (as shown in FIG. 12B), according to which the actuation is performed. After the piece 40 passes over the arm portion 53 (as shown in Fig. 12C), the actuating member 40 can again correspond to the arm portion 53 of the pusher member 44.

13A to 13C show a differential correction mechanism 300 according to another embodiment of the present invention. The implementation type. The difference correction mechanism 300 differs from the foregoing embodiment in that the horizontal portion 302 and the inclined portion 304 are directly formed on the first rail 26.

On the other hand, the pusher 306 can be in contact with the horizontal portion 302 and the inclined portion 304 by at least one contact portion (for example, a first contact portion 308 and a second contact portion 310) during active displacement. One. When the differential displacement of the carriage 312 is deviated, the actuating member 314 drives the pusher during the movable displacement of the second rail (actuator 314) from the collapsed position toward the extended position from the first direction D1. 306, the push member 306 is movably displaced from the horizontal position P1 to the inclined position P2 to drive the carriage 312 to correct the deviation of the differential displacement of the carriage 312, and the actuating member 314 is at the inclined position. P2 releases the pusher 306.

While the present invention has been disclosed in the foregoing preferred embodiments, it is not intended to limit the invention, and the scope of the invention is defined by the scope of the appended claims.
