[0029] Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.

[0030] It should be noted herein that for clarity of description, spatially relative terms such as “top,”“bottom,”“upper,”“lower,”“on,”“above,”“over,”“downwardly,”“upwardly” and the like may be used throughout the disclosure while making reference to the features as illustrated in the drawings. The features may be oriented differently (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein may be interpreted accordingly.

[0031] Referring to FIGS. 1 to 6, an embodiment of a slide rail assembly 20 according to the disclosure includes a lock device 10, a first rail 21, and a second rail 22. The lock device 10 includes a seat body 11, a movement member 12, and a lock member 13. In this embodiment, the seat body 11 is configured to be a bent plate, and has a fixation portion 111 and a positioning portion 112. The fixation portion 111 extends in a longitudinal direction. The positioning portion 112 is formed at an edge of the fixation portion 111, and extends in a transverse direction that is transverse to the longitudinal direction. The fixation portion 111 and the positioning portion 112 of the seat body 11 may be formed by bending the seat body 11 such that the fixation portion 111 and the positioning portion 112 are connected to each other and cooperatively form an L-shaped structure (i.e., the positioning portion 112 is bent relative to the fixation portion 111). The fixation portion 111 has at least one first hole (H1). The positioning portion 112 has a second hole (H2). The seat body 11 further has a groove 113 that is located between the fixation portion 111 and the positioning portion 112 thereof. In this embodiment, the fixation portion 111 has two first holes (H1). In this embodiment, the groove 113 may be configured to be a gap that is recessed from a bottom of a junction between the fixation portion 111 and the positioning portion 112, but may not be limited thereto.

[0032] The movement member 12 is movably connected to the seat body 11. In this embodiment, the movement member 12 has an operation portion 121 and an abutment portion 122 that is formed at an edge of the operation portion 121. The operation portion 121 is configured to be plate-shaped. The abutment portion 122 extends from the edge of the operation portion 121, and is bent relative to the operation portion 121 (i.e., the operation portion 121 and the abutment portion 122 of the movement member 12 may be formed by bending the movement member 12). The operation portion 121 has a third hole (H3) and a fourth hole (H4). The third hole (H3) is closer to the abutment portion 122 than the fourth hole (H4) is, and is aligned with the second hole (H2) of the positioning portion 112 of the seat body 11. A connection member 123 extends through the third hole (H3) and the second hole (H2) and defines a rotation axis (R) so that the operation portion 121 of the movement member 12 is rotatably connected to the positioning portion 112 of the seat body 11. The movement member 12 is operable to move relative to the seat body 11 between a first position (D1) and a second position (D2). Referring to FIGS. 5 and 7, when the movement member 12 is in the first position (D1), the abutment portion 122 of the movement member 12 is located at one side of the positioning portion 112 of the seat body 11, and is spaced apart from the fixation portion 111 of the seat body 11. Referring to FIGS. 6 and 8, when the movement member 12 is in the second position (D2), the abutment portion 122 of the movement member 12 is located at another side of the positioning portion 112 of the seat body 11, and at least partially engages the groove 113 of the seat body 11 so that the movement member 12 is positioned. Referring to FIGS. 3 and 5 to 8, a thickness (T) of the positioning portion 112 of the seat body 11 may serve as a positioning feature (A), and the abutment portion 122 of the movement member 12 has a rotation feature (B). The rotation feature (B) corresponds in position to the positioning feature (A), and moves along the positioning feature (A) when the movement member 12 moves relative to the seat body 11 (i.e., the abutment portion 122 of the movement member 12 moves along the positioning portion 112 of the seat body 11 when the movement member 12 moves relative to the seat body 11). Specifically, the positioning feature (A) may be configured to be an edge of the positioning portion 112 of the seat body 11, and the rotation feature (B) may be configured to be a surface of the abutment portion 122 of the movement member 12 that faces the positioning portion 112. In this embodiment, the movement member 12 is operable to rotate relative to the seat body 11 (i.e., the movement member 12 and the seat body 11 are rotatably connected), but may not be limited thereto. In one embodiment, the movement member 12 and the seat body 11 may be movably coupled to each other such that the movement member 12 is movable but not rotatable relative to the seat body 11.

[0033] The lock member 13 is disposed on the movement member 12 so that the lock member 13 moves together with the movement member 12. Referring to FIGS. 5 and 7, when the movement member 12 is in the first position (D1), the lock member 13 is in a lock position (K1), and the lock device 10 is in a closed state. Referring to FIGS. 6 and 8, when the movement member 12 is in the second position (D2), the lock member 13 is in an unlock position (K2), and the lock device 10 is in an open state. In this embodiment, the lock member 13 has a head portion 131, a lock portion 132, and a neck portion 133 that is located between the head portion 131 and the lock portion 132. The neck portion 133 corresponds in position to the fourth hole (H4) of the operation portion 121 of the movement member 12. Specifically, the neck portion 133 of the lock member 13 extends through the fourth hole (H4) of the operation portion 121 of the movement member 12 so that the lock member 13 is disposed on the movement member 12. The lock portion 132 of the lock member 13 and the seat body 11 are located at a same side of the operation portion 121 of the movement member 12. In this embodiment, when the movement member 12 is in the first position (D1), the abutment portion 122 of the movement member 12 is located at the one side of the positioning portion 112 of the seat body 11, and the lock member 13 is in the lock position (K1). When the movement member 12 is in the second position (D2), the lock member 13 is in the unlock position (K2), and the abutment portion 122 of the movement member 12 is located at the another side of the positioning portion 112 of the seat body 11, and at least partially engages the groove 113 of the seat body 11 so that the movement member 12 is positioned. In one embodiment, when the movement member 12 moves but does not rotate relative to the seat body 11, the abutment portion 122 of the movement member 12 may move along the positioning portion 112 of the seat body 11 to engage the groove 113.

[0034] Referring to FIGS. 7 and 8, in this embodiment, the rotation axis (R) that is defined by the connection member 123 defines an imaginary vertical plane (P). When the lock member 13 is in the lock position (K1), the lock member 13 is located at one side of the imaginary vertical plane (P). When the lock member 13 is in the unlock position (K2), the lock member 13 is located at another side of the imaginary vertical plane (P). When a center of gravity of a combination of the movement member 12 and the lock member 13 is located at the one side of the imaginary vertical plane (P), the movement member 12 is urged to move to the first position (D1) by gravity such that the lock member 13 is urged to move to the lock position (K1). When the center of gravity of the combination of the movement member 12 and the lock member 13 is located at the another side of the imaginary vertical plane (P), the movement member 12 is urged to move to the second position (D2) by the gravity such that the lock member 13 is urged to move to the unlock position (K2). It is noted that, in one embodiment, the movement member 12 may be movable but not rotatable relative to the seat body 11 (i.e., the rotation axis (R) is omitted), and the imaginary vertical plane (P) may be an imaginary vertical plane that is adjacent to a junction between the seat body 11 and the movement member 12.

[0035] Referring to FIGS. 1 and 2 again, the first rail 21 may be configured to be an inner frame. The first rail 21 has a first lateral surface 211 that faces the second rail 22, and a second lateral surface 212 that is opposite to the first lateral surface 211. The seat body 11 of the lock device 10 is disposed on the first rail 21. The first lateral surface 211 of the first rail 21 has at least one protrusion 213 that engages the at least one first hole (H1) of the fixation portion 111 of the seat body 11 so that the seat body 11 is fixedly mounted to the first lateral surface 211 of the first rail 21. In this embodiment, the first rail 21 has two protrusions 213 that respectively engage the first holes (H1) of the fixation portion 111 of the seat body 11. The second lateral surface 212 may be adapted to be mounted to a server chassis (not shown), but may not be limited thereto. Referring to FIGS. 9 to 12, when the lock member 13 is in the lock position (K1), the lock member 13 is located at one side of the first lateral surface 211 opposite to the second lateral surface 212. Referring to FIGS. 13 to 16, when the lock member 13 is in the unlock position (K2), the lock member 13 is located at one side of the second lateral surface 212 opposite to the first lateral surface 211.

[0036] The second rail 22 has a first end surface 221 and a second end surface 222. The first rail 21 is operable to move relative to the second rail 22 in a front-rear direction. In this embodiment, the front-rear direction is parallel to the longitudinal direction. The second rail 22 includes an intermediate frame 223 and an outer frame 224. Each of the intermediate frame 223 and the outer frame 224 has two opposite end surfaces. One of the end surfaces of the intermediate frame 223 and one of the end surfaces of the outer frame 224 that is adjacent to the one of the end surfaces of the intermediate frame 223 cooperatively serve as the first end surface 221. Another one of the end surfaces of the intermediate frame 223 and another one of the end surfaces of the outer frame 224 that is adjacent to the another one of the end surfaces of the intermediate frame 223 cooperatively serve as the second end surface 222. Referring to FIGS. 11 to 14, when the movement member 12 is located in front of the first end surface 221 of the second rail 22, the movement member 12 is operable to move between the first position (D1) and the second position (D2). At this time, when the movement member 12 is in the first position (D1) and when the first rail 21 retracts (i.e., when the first rail 21 is urged to move toward the second end surface 222 of the second rail 22), the movement member 12 is blocked by the intermediate frame 223 and the outer frame 224 such that the movement member 12 is not allowed to move past the first end surface 221 of the second rail 22 toward the second end surface 222. Referring to FIGS. 15 and 16, when the movement member 12 is in the second position (D2), the movement member 12 is allowed to move past the first end surface 221 toward the second end surface 222 while the first rail 21 is urged to move toward the second end surface 222, and is allowed to move past the first end surface 221 away from the second end surface 222 while the first rail 21 is urged to move away from the second end surface 222. That is to say, when the movement member 12 is in the second position (D2), the movement member 12 and the lock member 13 are not blocked by the second rail 22 while the first rail 21 retracts so that the movement member 12, the lock member 13 and the server chassis are allowed to retract with the first rail 21. When the lock device 10 is in the open state, the lock device 10 and the inner frame (i.e., the first rail 21) are allowed to retract into the intermediate frame 223.

[0037] The slide rail assembly 20 may further includes a lock seat 23 that serves as a supporting frame. The lock seat 23 is disposed on one end of the second rail 22 that has the first end surface 221. When the movement member 12 is in the first position (D1), the lock member 13 is aligned with the lock seat 23 along the front-rear direction. When the movement member 12 is located in front of the first end surface 221 of the second rail 22 and is in the second position (D2), the lock member 13 and the lock seat 23 are misaligned with each other. In this embodiment, the lock seat 23 has a lock hole 231 that has an internal thread, and the lock portion 132 of the lock member 13 has an external thread so that the lock portion 132 of the lock member 13 is operable to threadedly engage the lock hole 231. In this embodiment, the lock device 10 may be locked at the lock seat 23 when the lock device 10 is in the closed state, but may not be limited thereto.

[0038] Referring to FIG. 17, the first rail 21 further has a rail end surface 214. The positioning portion 112 of the seat body 11 is spaced apart from the rail end surface 214 in the front-rear direction, and cooperates with the rail end surface 214 to define a first adjustment distance (L1) therebetween in the front-rear direction. When the first rail 21 is not long enough for required operations of the slide rail assembly 20, the seat body 11 may be replaced with another seat body that has a longer fixation portion to increase the first adjustment distance (L1). Therefore, without replacement of the first rail 21, an overall length of the slide rail assembly 20 in the front-rear direction is still adjustable. The lock member 13 cooperates with another edge of the operation portion 121 of the movement member 12 opposite to the abutment portion 122 of the movement member 12 to define a second adjustment distance (L2) therebewteen. When the movement member 12 is in the first position (D1) but the lock member 13 is deviated from the lock hole 231 of the lock seat 23 in the transverse direction, a user of the slide rail assembly 20 may replace the movement member 12 with another movement member according to a length of deviation of the lock member 13 in the transverse direction so that the lock member 13 may be aligned with the lock hole 231 when the movement member 12 is in the first position (D1). Therefore, without replacement of the lock seat 23 or replacement of the entire lock device 10, the deviation of the lock member 13 may still be corrected.

[0039] Referring to FIG. 18, a method for operating the slide rail assembly 20 includes a first providing step (S1), a second providing step (S2), a first operating step (S3), and a second operating step (S4). In the first providing step (S1) of the method, the first rail 21 and the lock device 10 are provided. The lock device 10 is disposed on the first rail 21. The lock device 10 includes the seat body 11, the movement member 12, and the lock member 13. The movement member 12 is movably connected to the seat body 11, and the lock member 13 is disposed on the movement member 12. In the second providing step (S2), the second rail 22 and the lock seat 23 are provided. The second rail 22 has the first end surface 221 and the second end surface 222. The lock seat 23 is disposed on the second rail 22. The first rail 21 is operable to move relative to the second rail 22 in the front-rear direction. In the first operating step (S3), the movement member 12 is operable to move between the first position (D1) and the second position (D2) when the movement member 12 is located in front of the first end surface 221 of the second rail 22. In the second operating step (S4), when the movement member 12 is moved relative to the seat body 11 to the first position (D1), the lock member 13 moves together with the movement member 12 to the lock position (K1). When the movement member 12 is in the first position (D1) (i.e., when the lock member 13 is in the lock position (K1)), the lock member 13 is aligned with the lock seat 23 along the front-rear direction. When the movement member 12 is moved relative to the seat body 11 to the second position (D2), the lock member 13 moves together with the movement member 12 to the unlock position (K2). When the movement member 12 is located in front of the first end surface 221 of the second rail 22 and is in the second position (D2) (i.e., when the lock member 13 is in the unlock position (K2)), the lock member 13 and the lock seat 23 are misaligned with each other so that the movement member 12 is allowed to move past the first end surface 221 toward the second end surface 222 while the first rail 21 is urged to move toward the second end surface 222.

[0040] Referring to FIGS. 19 and 20, a fixation member 30 is disposed on the lock seat 23, and the slide rail assembly 20 is adapted to be mounted to a column of a machine (e.g., a piece of server equipment, or a server rack) (not shown) via the fixation member 30. The movement member 12 and the fixation member 30 cooperatively define an imaginary point (I). When the movement member 12 is located at the imaginary point (I), the movement member 12 is operable to move between the first position (D1) and the second position (D2), and the movement member 12 is in front of and closest to the fixation member 30. It is noted that the imaginary point (I) is deviated in the transverse direction in FIG. 19 for clear illustration of the fixation member 30 and the slide rail assembly 20. When the movement member 12 moves past the first end surface 221 away from the second end surface 222 and reaches the imaginary point (I) while the first rail 21 extends (i.e., while the first rail 21 is urged to move away from the second end surface 222), the movement member 12 is operable to move from second position (D2) to the first position (D1) so that the lock member 13 may be aligned with and locked at the lock seat 23. When the movement member 12 is in front of the imaginary point (I) and then is urged to reach the imaginary point (I) while the first rail 21 retracts, if the movement member 12 is in the second position (D2), the movement member 12 and the lock member 13 are not blocked by any one of the second rail 22, the lock seat 23, the column of the machine and the fixation member 30, and are allowed to retract with the first rail 21 so that the server chassis may retract. A distance that the movement member 12 has to travel from a location at which the first rail 21 retracts into the second rail 22 to the imaginary point (I) in the front-rear direction is defined to be a journey distance (L). The journey distance (L) equals to a distance that the rail end surface 214 of the first rail 21 has to travel from the location at which the first rail 21 retracts into the second rail 22 to a location at which the first rail 21 and the second rail 22 engage each other. It is noted that, because the movement member 12 is spaced apart from the rail end surface 214 in the front-rear direction, the journey distance (L) is longer than a distance that, when the lock device 10 is omitted, the rail end surface 214 of the first rail 21 has to travel from the location at which the first rail 21 retracts into the second rail 22 to the location at which the first rail 21 and the second rail 22 engage each other.

[0041] In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,”“an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects; such does not mean that every one of these features needs to be practiced with the presence of all the other features. In other words, in any described embodiment, when implementation of one or more features or specific details does not affect implementation of another one or more features or specific details, said one or more features may be singled out and practiced alone without said another one or more features or specific details. It should be further noted that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.

[0042] While the disclosure has been described in connection with what is(are) considered the exemplary embodiment(s), it is understood that this disclosure is not limited to the disclosed embodiment(s) but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.

[0029] Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.

[0030] It should be noted herein that for clarity of description, spatially relative terms such as “top,”“bottom,”“upper,”“lower,”“on,”“above,”“over,”“downwardly,”“upwardly” and the like may be used throughout the disclosure while making reference to the features as illustrated in the drawings. The features may be oriented differently (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein may be interpreted accordingly.

[0031] Referring to FIGS. 1 to 6, an embodiment of a slide rail assembly 20 according to the disclosure includes a lock device 10, a first rail 21, and a second rail 22. The lock device 10 includes a seat body 11, a movement member 12, and a lock member 13. In this embodiment, the seat body 11 is configured to be a bent plate, and has a fixation portion 111 and a positioning portion 112. The fixation portion 111 extends in a longitudinal direction. The positioning portion 112 is formed at an edge of the fixation portion 111, and extends in a transverse direction that is transverse to the longitudinal direction. The fixation portion 111 and the positioning portion 112 of the seat body 11 may be formed by bending the seat body 11 such that the fixation portion 111 and the positioning portion 112 are connected to each other and cooperatively form an L-shaped structure (i.e., the positioning portion 112 is bent relative to the fixation portion 111). The fixation portion 111 has at least one first hole (H1). The positioning portion 112 has a second hole (H2). The seat body 11 further has a groove 113 that is located between the fixation portion 111 and the positioning portion 112 thereof. In this embodiment, the fixation portion 111 has two first holes (H1). In this embodiment, the groove 113 may be configured to be a gap that is recessed from a bottom of a junction between the fixation portion 111 and the positioning portion 112, but may not be limited thereto.

[0032] The movement member 12 is movably connected to the seat body 11. In this embodiment, the movement member 12 has an operation portion 121 and an abutment portion 122 that is formed at an edge of the operation portion 121. The operation portion 121 is configured to be plate-shaped. The abutment portion 122 extends from the edge of the operation portion 121, and is bent relative to the operation portion 121 (i.e., the operation portion 121 and the abutment portion 122 of the movement member 12 may be formed by bending the movement member 12). The operation portion 121 has a third hole (H3) and a fourth hole (H4). The third hole (H3) is closer to the abutment portion 122 than the fourth hole (H4) is, and is aligned with the second hole (H2) of the positioning portion 112 of the seat body 11. A connection member 123 extends through the third hole (H3) and the second hole (H2) and defines a rotation axis (R) so that the operation portion 121 of the movement member 12 is rotatably connected to the positioning portion 112 of the seat body 11. The movement member 12 is operable to move relative to the seat body 11 between a first position (D1) and a second position (D2). Referring to FIGS. 5 and 7, when the movement member 12 is in the first position (D1), the abutment portion 122 of the movement member 12 is located at one side of the positioning portion 112 of the seat body 11, and is spaced apart from the fixation portion 111 of the seat body 11. Referring to FIGS. 6 and 8, when the movement member 12 is in the second position (D2), the abutment portion 122 of the movement member 12 is located at another side of the positioning portion 112 of the seat body 11, and at least partially engages the groove 113 of the seat body 11 so that the movement member 12 is positioned. Referring to FIGS. 3 and 5 to 8, a thickness (T) of the positioning portion 112 of the seat body 11 may serve as a positioning feature (A), and the abutment portion 122 of the movement member 12 has a rotation feature (B). The rotation feature (B) corresponds in position to the positioning feature (A), and moves along the positioning feature (A) when the movement member 12 moves relative to the seat body 11 (i.e., the abutment portion 122 of the movement member 12 moves along the positioning portion 112 of the seat body 11 when the movement member 12 moves relative to the seat body 11). Specifically, the positioning feature (A) may be configured to be an edge of the positioning portion 112 of the seat body 11, and the rotation feature (B) may be configured to be a surface of the abutment portion 122 of the movement member 12 that faces the positioning portion 112. In this embodiment, the movement member 12 is operable to rotate relative to the seat body 11 (i.e., the movement member 12 and the seat body 11 are rotatably connected), but may not be limited thereto. In one embodiment, the movement member 12 and the seat body 11 may be movably coupled to each other such that the movement member 12 is movable but not rotatable relative to the seat body 11.

[0033] The lock member 13 is disposed on the movement member 12 so that the lock member 13 moves together with the movement member 12. Referring to FIGS. 5 and 7, when the movement member 12 is in the first position (D1), the lock member 13 is in a lock position (K1), and the lock device 10 is in a closed state. Referring to FIGS. 6 and 8, when the movement member 12 is in the second position (D2), the lock member 13 is in an unlock position (K2), and the lock device 10 is in an open state. In this embodiment, the lock member 13 has a head portion 131, a lock portion 132, and a neck portion 133 that is located between the head portion 131 and the lock portion 132. The neck portion 133 corresponds in position to the fourth hole (H4) of the operation portion 121 of the movement member 12. Specifically, the neck portion 133 of the lock member 13 extends through the fourth hole (H4) of the operation portion 121 of the movement member 12 so that the lock member 13 is disposed on the movement member 12. The lock portion 132 of the lock member 13 and the seat body 11 are located at a same side of the operation portion 121 of the movement member 12. In this embodiment, when the movement member 12 is in the first position (D1), the abutment portion 122 of the movement member 12 is located at the one side of the positioning portion 112 of the seat body 11, and the lock member 13 is in the lock position (K1). When the movement member 12 is in the second position (D2), the lock member 13 is in the unlock position (K2), and the abutment portion 122 of the movement member 12 is located at the another side of the positioning portion 112 of the seat body 11, and at least partially engages the groove 113 of the seat body 11 so that the movement member 12 is positioned. In one embodiment, when the movement member 12 moves but does not rotate relative to the seat body 11, the abutment portion 122 of the movement member 12 may move along the positioning portion 112 of the seat body 11 to engage the groove 113.

[0034] Referring to FIGS. 7 and 8, in this embodiment, the rotation axis (R) that is defined by the connection member 123 defines an imaginary vertical plane (P). When the lock member 13 is in the lock position (K1), the lock member 13 is located at one side of the imaginary vertical plane (P). When the lock member 13 is in the unlock position (K2), the lock member 13 is located at another side of the imaginary vertical plane (P). When a center of gravity of a combination of the movement member 12 and the lock member 13 is located at the one side of the imaginary vertical plane (P), the movement member 12 is urged to move to the first position (D1) by gravity such that the lock member 13 is urged to move to the lock position (K1). When the center of gravity of the combination of the movement member 12 and the lock member 13 is located at the another side of the imaginary vertical plane (P), the movement member 12 is urged to move to the second position (D2) by the gravity such that the lock member 13 is urged to move to the unlock position (K2). It is noted that, in one embodiment, the movement member 12 may be movable but not rotatable relative to the seat body 11 (i.e., the rotation axis (R) is omitted), and the imaginary vertical plane (P) may be an imaginary vertical plane that is adjacent to a junction between the seat body 11 and the movement member 12.

[0035] Referring to FIGS. 1 and 2 again, the first rail 21 may be configured to be an inner frame. The first rail 21 has a first lateral surface 211 that faces the second rail 22, and a second lateral surface 212 that is opposite to the first lateral surface 211. The seat body 11 of the lock device 10 is disposed on the first rail 21. The first lateral surface 211 of the first rail 21 has at least one protrusion 213 that engages the at least one first hole (H1) of the fixation portion 111 of the seat body 11 so that the seat body 11 is fixedly mounted to the first lateral surface 211 of the first rail 21. In this embodiment, the first rail 21 has two protrusions 213 that respectively engage the first holes (H1) of the fixation portion 111 of the seat body 11. The second lateral surface 212 may be adapted to be mounted to a server chassis (not shown), but may not be limited thereto. Referring to FIGS. 9 to 12, when the lock member 13 is in the lock position (K1), the lock member 13 is located at one side of the first lateral surface 211 opposite to the second lateral surface 212. Referring to FIGS. 13 to 16, when the lock member 13 is in the unlock position (K2), the lock member 13 is located at one side of the second lateral surface 212 opposite to the first lateral surface 211.

[0036] The second rail 22 has a first end surface 221 and a second end surface 222. The first rail 21 is operable to move relative to the second rail 22 in a front-rear direction. In this embodiment, the front-rear direction is parallel to the longitudinal direction. The second rail 22 includes an intermediate frame 223 and an outer frame 224. Each of the intermediate frame 223 and the outer frame 224 has two opposite end surfaces. One of the end surfaces of the intermediate frame 223 and one of the end surfaces of the outer frame 224 that is adjacent to the one of the end surfaces of the intermediate frame 223 cooperatively serve as the first end surface 221. Another one of the end surfaces of the intermediate frame 223 and another one of the end surfaces of the outer frame 224 that is adjacent to the another one of the end surfaces of the intermediate frame 223 cooperatively serve as the second end surface 222. Referring to FIGS. 11 to 14, when the movement member 12 is located in front of the first end surface 221 of the second rail 22, the movement member 12 is operable to move between the first position (D1) and the second position (D2). At this time, when the movement member 12 is in the first position (D1) and when the first rail 21 retracts (i.e., when the first rail 21 is urged to move toward the second end surface 222 of the second rail 22), the movement member 12 is blocked by the intermediate frame 223 and the outer frame 224 such that the movement member 12 is not allowed to move past the first end surface 221 of the second rail 22 toward the second end surface 222. Referring to FIGS. 15 and 16, when the movement member 12 is in the second position (D2), the movement member 12 is allowed to move past the first end surface 221 toward the second end surface 222 while the first rail 21 is urged to move toward the second end surface 222, and is allowed to move past the first end surface 221 away from the second end surface 222 while the first rail 21 is urged to move away from the second end surface 222. That is to say, when the movement member 12 is in the second position (D2), the movement member 12 and the lock member 13 are not blocked by the second rail 22 while the first rail 21 retracts so that the movement member 12, the lock member 13 and the server chassis are allowed to retract with the first rail 21. When the lock device 10 is in the open state, the lock device 10 and the inner frame (i.e., the first rail 21) are allowed to retract into the intermediate frame 223.

[0037] The slide rail assembly 20 may further includes a lock seat 23 that serves as a supporting frame. The lock seat 23 is disposed on one end of the second rail 22 that has the first end surface 221. When the movement member 12 is in the first position (D1), the lock member 13 is aligned with the lock seat 23 along the front-rear direction. When the movement member 12 is located in front of the first end surface 221 of the second rail 22 and is in the second position (D2), the lock member 13 and the lock seat 23 are misaligned with each other. In this embodiment, the lock seat 23 has a lock hole 231 that has an internal thread, and the lock portion 132 of the lock member 13 has an external thread so that the lock portion 132 of the lock member 13 is operable to threadedly engage the lock hole 231. In this embodiment, the lock device 10 may be locked at the lock seat 23 when the lock device 10 is in the closed state, but may not be limited thereto.

[0038] Referring to FIG. 17, the first rail 21 further has a rail end surface 214. The positioning portion 112 of the seat body 11 is spaced apart from the rail end surface 214 in the front-rear direction, and cooperates with the rail end surface 214 to define a first adjustment distance (L1) therebetween in the front-rear direction. When the first rail 21 is not long enough for required operations of the slide rail assembly 20, the seat body 11 may be replaced with another seat body that has a longer fixation portion to increase the first adjustment distance (L1). Therefore, without replacement of the first rail 21, an overall length of the slide rail assembly 20 in the front-rear direction is still adjustable. The lock member 13 cooperates with another edge of the operation portion 121 of the movement member 12 opposite to the abutment portion 122 of the movement member 12 to define a second adjustment distance (L2) therebewteen. When the movement member 12 is in the first position (D1) but the lock member 13 is deviated from the lock hole 231 of the lock seat 23 in the transverse direction, a user of the slide rail assembly 20 may replace the movement member 12 with another movement member according to a length of deviation of the lock member 13 in the transverse direction so that the lock member 13 may be aligned with the lock hole 231 when the movement member 12 is in the first position (D1). Therefore, without replacement of the lock seat 23 or replacement of the entire lock device 10, the deviation of the lock member 13 may still be corrected.

[0039] Referring to FIG. 18, a method for operating the slide rail assembly 20 includes a first providing step (S1), a second providing step (S2), a first operating step (S3), and a second operating step (S4). In the first providing step (S1) of the method, the first rail 21 and the lock device 10 are provided. The lock device 10 is disposed on the first rail 21. The lock device 10 includes the seat body 11, the movement member 12, and the lock member 13. The movement member 12 is movably connected to the seat body 11, and the lock member 13 is disposed on the movement member 12. In the second providing step (S2), the second rail 22 and the lock seat 23 are provided. The second rail 22 has the first end surface 221 and the second end surface 222. The lock seat 23 is disposed on the second rail 22. The first rail 21 is operable to move relative to the second rail 22 in the front-rear direction. In the first operating step (S3), the movement member 12 is operable to move between the first position (D1) and the second position (D2) when the movement member 12 is located in front of the first end surface 221 of the second rail 22. In the second operating step (S4), when the movement member 12 is moved relative to the seat body 11 to the first position (D1), the lock member 13 moves together with the movement member 12 to the lock position (K1). When the movement member 12 is in the first position (D1) (i.e., when the lock member 13 is in the lock position (K1)), the lock member 13 is aligned with the lock seat 23 along the front-rear direction. When the movement member 12 is moved relative to the seat body 11 to the second position (D2), the lock member 13 moves together with the movement member 12 to the unlock position (K2). When the movement member 12 is located in front of the first end surface 221 of the second rail 22 and is in the second position (D2) (i.e., when the lock member 13 is in the unlock position (K2)), the lock member 13 and the lock seat 23 are misaligned with each other so that the movement member 12 is allowed to move past the first end surface 221 toward the second end surface 222 while the first rail 21 is urged to move toward the second end surface 222.

[0040] Referring to FIGS. 19 and 20, a fixation member 30 is disposed on the lock seat 23, and the slide rail assembly 20 is adapted to be mounted to a column of a machine (e.g., a piece of server equipment, or a server rack) (not shown) via the fixation member 30. The movement member 12 and the fixation member 30 cooperatively define an imaginary point (I). When the movement member 12 is located at the imaginary point (I), the movement member 12 is operable to move between the first position (D1) and the second position (D2), and the movement member 12 is in front of and closest to the fixation member 30. It is noted that the imaginary point (I) is deviated in the transverse direction in FIG. 19 for clear illustration of the fixation member 30 and the slide rail assembly 20. When the movement member 12 moves past the first end surface 221 away from the second end surface 222 and reaches the imaginary point (I) while the first rail 21 extends (i.e., while the first rail 21 is urged to move away from the second end surface 222), the movement member 12 is operable to move from second position (D2) to the first position (D1) so that the lock member 13 may be aligned with and locked at the lock seat 23. When the movement member 12 is in front of the imaginary point (I) and then is urged to reach the imaginary point (I) while the first rail 21 retracts, if the movement member 12 is in the second position (D2), the movement member 12 and the lock member 13 are not blocked by any one of the second rail 22, the lock seat 23, the column of the machine and the fixation member 30, and are allowed to retract with the first rail 21 so that the server chassis may retract. A distance that the movement member 12 has to travel from a location at which the first rail 21 retracts into the second rail 22 to the imaginary point (I) in the front-rear direction is defined to be a journey distance (L). The journey distance (L) equals to a distance that the rail end surface 214 of the first rail 21 has to travel from the location at which the first rail 21 retracts into the second rail 22 to a location at which the first rail 21 and the second rail 22 engage each other. It is noted that, because the movement member 12 is spaced apart from the rail end surface 214 in the front-rear direction, the journey distance (L) is longer than a distance that, when the lock device 10 is omitted, the rail end surface 214 of the first rail 21 has to travel from the location at which the first rail 21 retracts into the second rail 22 to the location at which the first rail 21 and the second rail 22 engage each other.

[0041] In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment(s). It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,”“an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects; such does not mean that every one of these features needs to be practiced with the presence of all the other features. In other words, in any described embodiment, when implementation of one or more features or specific details does not affect implementation of another one or more features or specific details, said one or more features may be singled out and practiced alone without said another one or more features or specific details.
