DETAILED DESCRIPTION
FIG. 1 shows a pair of slide rail assemblies 10 applied to a system 12 according to an embodiment of the present invention. The system 12 can be furniture or a cabinet. In the present embodiment, the system comprises a first furniture part 14 and at least one second furniture part 16. The at least one second furniture part 16 can be two drawers for example. The pair of the slide rail assemblies 10 is mounted between the first furniture part 14 and the second furniture part 16. In the present embodiment, the slide rail assemblies 10 are undermount drawer slides, and are respectively mounted to the second furniture part 16 to be adjacent to two sides of a bottom of the second furniture part 16. According to the above arrangement, the second furniture part 16 can be easily opened or closed relative to the first furniture part 14 through the pair of slide rail assemblies 10.
As shown in FIG. 2, the slide rail assembly 10 comprises a first rail 18 and a second rail 20. Preferably, the slide rail assembly further comprises a third rail 22. The first rail 18 is longitudinally and fixedly mounted to the first furniture part 14. The second rail 20 and the third rail 22 are longitudinally movable relative to the first rail 18. The third rail 22 is movably mounted between the first rail 18 and the second rail 20. The third rail 22 is configured to extend a traveling distance of the second rail 20 relative to the first rail 18.
As shown in FIG. 3 and FIG. 4, the second rail 20 of the slide rail assembly 10 comprises an adjusting hole 24 adjacent to a front end of the second rail 20 and a plurality of protruded connection features 26. The slide rail assembly 10 further comprises a carrying member 28, a plurality of fixing members 30 and an adjusting member 32. The carrying member 28 is movably mounted to the second rail 20. The carrying member 28 has a plurality of connection holes 34 and a through hole 36. The connection holes 34 correspond to the connection features 26 of the second rail 20, and the through hole 36 corresponds to the adjusting hole 24 of the second rail 20. Each of the fixing members 30 passes through a corresponding connection hole 34 of the carrying member 28 to connect to the second rail 20. Preferably, the slide rail assembly 10 further comprises a plurality of connection bases 38. Each of the fixing members 30 sequentially connects a corresponding connection base 38 and the carrying member 28 to a corresponding connection feature 26. The adjusting member 32 comprises an adjusting part 40 and an eccentric part 42 connected to the adjusting part 40. The adjusting part 40 is rotatably mounted to the carrying member 28. The eccentric part 42 passes through the through hole 36 of the carrying member 28 and the adjusting hole 24 of the second rail 20.
As shown in FIG. 5 to FIG. 8, a longitudinal dimension L1 of each connection hole 34 of the carrying member 28 is greater than an outer dimension of a portion of each fixing member 30 connected to the connection feature 26 of the second rail 20, such that the carrying member 28 is longitudinally movable relative to the second rail 20. The eccentric part 42 of the adjusting member 32 is deviated from a center position of the adjusting part 40 of the adjusting member 32. The eccentric part 42 is correspondingly arranged to pass through the through hole 36 of the carrying member 28 and the adjusting hole 24 of the second rail 20. A longitudinal dimension L2 of the adjusting hole 24 is greater than an outer dimension of the eccentric part 42 of the adjusting member 32. A longitudinal direction of the connection hole 34 is different from a longitudinal direction of the adjusting hole 24. Through utilizing the fixing members 30 to connect the carrying member 28 to the connection features 26 of the second rail 20 during assembly, the carrying member 28 can be mounted to the second rail 20 . Through rotating the adjusting part 40 of the adjusting member 32 to adjust the carrying member 28, the eccentric part 42 abuts against the second rail 20, such that the carrying member 28 can be moved relative to the second rail 20 along a longitudinal direction of the second rail 20. In other words, the carrying member 28 can be longitudinally moved relative to the second rail 20 along the longitudinal direction of the connection holes 34. Preferably, the carrying member 28 has a protruded stopping feature 44 configured to contact the adjusting member 32 in a proper tightness, such that the adjusting member 32 can be stably fixed after being adjusted.
As shown in FIG. 9, the slide rail assembly 10 further comprises a first sliding auxiliary device 46 and a second sliding auxiliary device 48. The first sliding auxiliary device 46 is movably arranged between the first rail 18 and the third rail 22, and the second sliding auxiliary device 48 is movably arranged between the third rail 22 and the second rail 20.
As shown in FIG. 10, the first sliding auxiliary device 46 comprises at least two parts mutually engaged. In the present embodiment, the first sliding auxiliary device 46 comprises a first part 50, a second part 52 and a third part 54 detachably connected to each other in an end to end manner. At least one first rolling member 56 is mounted to one of the first part 50, the second part 52 and the third part 54. The least one first rolling member 56 is configured to facilitate the third rail 22 to move relative to the first rail 18. Briefly, the least one first rolling member 56 is configured to facilitate the third rail 22 to move and capable of increasing smoothness of movement of the third rail 22 relative to the first rail 18. The second sliding auxiliary device 48 comprises at least two parts mutually engaged. In the present embodiment, the second sliding auxiliary device 48 comprises a first part 58, a second part 60 and a third part 62 detachably connected to each other in an end to end manner. At least one second rolling member 64 is mounted to one of the first part 58, the second part 60 and the third part 62. The least one second rolling member 64 is configured to facilitate the second rail 20 to move relative to the third rail 22. Briefly, the least one second rolling member 64 is configured to facilitate the second rail 20 to move and capable of increasing smoothness of movement of the second rail 20 relative to the third rail 22. According to the above arrangement, since the first sliding auxiliary device 46 and the second sliding auxiliary device 48 are formed by mutually engaging a plurality of parts, the user can adjust lengths of the sliding auxiliary devices by engaging a specific number of parts to correspond to a real length of the slide rail assembly. Specifically, the first part 50, the second part 52 and the third part 54 of the first sliding auxiliary device 46 have corresponding first hook parts 66 and first recessed parts 68 to be detachably engaged with each other. On the other hand, the first part 58, the second part 60 and the third part 62 of the second sliding auxiliary device 48 have corresponding second hook parts 70 and second recessed parts 72 to be detachably engaged with each other.
As shown in FIG. 11, the first part 50 and the second part 52 of the first sliding auxiliary device 46 can be mutually engaged and connected through engagement features of the corresponding first hook part 66 and first recessed part 68. For simplification, engagement between parts of the second sliding auxiliary device 48 is not further provided.
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.
