DETAILED DESCRIPTION

FIG. 1 is a diagram showing a carried object 10 mounted to a rack 14 through a pair of slide rail assemblies 12 according to an embodiment of the present invention. Specifically, the carried object 10 can be an electronic device or a chassis.
As shown in FIG. 1 and FIG. 2, each of the slide rail assemblies 12 comprises a support rail 16, a first rail 18 and a second rail 20. Wherein, the support rail 16 is mounted between a first post 22 a and a second post 22 b of the rack 14. The second rail 20 is configured to carry the carried object 10. The first rail 18 and the second rail 20 are movable relative to the support rail 16, such as being moved to switch from a retracted state to an extending state, so as to allow the carried object 10 to be moved from the inside of the rack 14 to the outside of the rack 14.
As shown in FIG. 3, the support rail 16 comprises a supporting passage 24 configured to accommodate the first rail 18. The first rail 18 comprises a passage 26. Specifically, the first rail 18 comprises a first wall 28 a, a second wall 28 b and a longitudinal wall 30 connected between the first wall 28 a and the second wall 28 b. The passage 26 is defined by the first wall 28 a, the second wall 28 b and the longitudinal wall 30, and configured to accommodate the second rail 20.
The second rail 20 comprises a main body part 32 and an extension part 34. Specifically, the main body part 32 of the second rail 20 comprises a first wall 36 a, a second wall 36 b and a longitudinal wall 38 connected between the first wall 36 a and the second wall 36 b.
As shown in FIG. 4, the first rail 18 is movably mounted to the support rail 16. The passage 26 of the first rail 18 has a first height H1. The main body part 32 of the second rail 20 has a second height H2. An end of the extension part 34 has a third height H3. Wherein, the first height H1 of the passage 26 of the first rail 18 is greater than the second height H2 of the main body part 32 of the second rail 20. The second height H2 of the main body part 32 of the second rail 20 is greater than the third height H3 of the end of the extension part 34. The first wall 36 a of the second rail 20 extends beyond the second wall 36 b of the second rail 20 a predetermined distance L along with the extension part 34. In other words, the first wall 36 a of the second rail 20 is longer than the second wall 36 b of the second rail 20.
As shown in FIG. 4 and FIG. 5, during a mounting process, a user can mount the second rail 20 into the passage 26 of the first rail 18 along a direction D. In such process, the extension part 34 is configured to be operatively placed into the passage 26 of the first rail 18 and supported by the first wall 28 a of the first rail 18. Therefore, the second rail 20 can be rapidly aligned to the passage 26 of the first rail 18, in order to facilitate mounting the second rail 20 into the passage 26 of the first rail 18. Preferably, the slide rail assembly 12 further comprises a first supporting member 40 and a second supporting member 42 respectively arranged on the first wall 28 a and the second wall 28 b within the passage 26 of the first rail 18. The first supporting member 40 and the second supporting member 42 are configured to guide or support the second rail 20. In the present embodiment, the extension part 34 of the second rail 20 can be supported by the first supporting member 40 on the first wall 28 a of the first rail 18.
As shown in FIG. 5 and FIG. 6, when the second rail 20 is further moved relative to the first rail 18 along the direction D, the main body part 32 of the second rail 20 enters into the passage 26 of the first rail 18. Wherein, when the main body part 32 of the second rail 20 enters into the passage 26 of the first rail 18, the first wall 36 a and the second wall 36 b of the main body part 32 of the second rail 20 respectively correspond to the first wall 28 a and the second wall 28 b of the first rail 18.
As shown in FIG. 7 and FIG. 8, the extension part 34 of the second rail 20 further comprises a guiding surface 44 located between the first wall 36 a and the second wall 36 b of the second rail 20. The guiding surface 44 can be an inclined surface or a curved surface. In the process of mounting the second rail 20 into the passage 26 of the first rail 18, if the second rail 20 is tilted relative to the first rail 18, the second rail 20 can be guided by the guiding surface 44 to enter the passage 26 of the first rail 18.
FIG. 9 is a diagram showing another embodiment of the second rail 200. A difference between the present embodiment and the previous embodiment is that the second rail 200 has an L shaped end portion. For example, the extension part 202 evenly extends beyond the second wall 206 of the second rail 200 a predetermined distance as well as the first wall 204 of the second rail 200, such that the first wall 204 of the second rail 200 is longer than the second wall 206 of the second rail 200. Therefore, during a mounting process, the second rail 200 can be supported by the first wall 210 of the first rail 208 through the extension part 202.
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.
