[0020] like Figure 1 As shown, a plurality of slide rail assemblies 20 of the first embodiment of the present invention can be used to mount a carrier 22 to a frame 24. Each slide rail assembly 20 has substantially the same structural configuration. For example, the slide rail assembly 20 includes a first rail 26, a second rail 28, and preferably, also includes a third rail 30. The first rail 26 is movably mounted between the third rail 30 and the second rail 28, and the first rail 26 can be used to extend the displacement stroke of the second rail 28 relative to the third rail 30. The third rail 30 (e.g., an outer rail), the first rail 26 (e.g., a middle rail), and the second rail 28 (e.g., an inner rail) can be longitudinally displaced relative to each other. As shown in FIG. Figure 1 In the figure, the X-axis is the longitudinal direction (or the length direction of the slide rail), the Y-axis is the transverse direction (or the lateral direction of the slide rail), and the Z-axis is the vertical direction (or the height direction of the slide rail).

[0021] Furthermore, the third rail 30 is used to be installed on the frame 24, and the second rail 28 is used to carry the load 22, wherein the second rail 28 of each slide rail assembly 20 can be displaced in a first predetermined direction D1 (for example, an opening direction) relative to the first rail 26 to a predetermined position P (for example, an extended position), so that at least a portion of the load 22 is located outside the frame 24.

[0022] like Figure 2As shown, the first rail 26 includes a blocking feature 32. The blocking feature 32 can be directly or indirectly disposed on the first rail 26, and the blocking feature 32 is exemplified by a protrusion, but is not limited in implementation. Preferably, the blocking feature 32 is disposed at an end 26a adjacent to the first rail 26, such as the front end, but is not limited in implementation. The slide rail assembly 20 also includes a working mechanism 34, a latch 36 and an operating member 38. The working mechanism 34, the latch 36 and the operating member 38 are disposed on the second rail 28. The operating member 38 is used to operate the working mechanism 34, and here, the operating member 38 is used to operably connect the working mechanism 34 and the latch 36 as an example. Among them, the second rail 28 (also referred to as a slide rail), the working mechanism 34, the latch 36 and the operating member 38 can together constitute a slide rail kit.

[0023] When the second rail 28 is at the predetermined position P relative to the first rail 26 and the operating member 38 is at a first operating position K1, the working mechanism 34 is in a first state S1 and can block the blocking feature 32 of the first rail 26 to prevent the second rail 28 from moving relative to the first rail 26 from the predetermined position P to the first predetermined direction D1 and / or a second predetermined direction D2 (for example, a folding direction) opposite to the first predetermined direction D1.

[0024] Preferably, the working mechanism 34 includes a pair of working members, such as a first working member 40 and a second working member 42 , which are pivotally connected to the second rail 28 via a first shaft 44 and a second shaft 46 , respectively.

[0025] Preferably, the slide rail assembly 20 further includes at least one elastic feature, such as a first elastic feature 48 and a second elastic feature 50 integrated into a seat 52, and the seat 52 is disposed (e.g., fixed) on the second rail 28. Further, the first working member 40 and the second working member 42 can be maintained in the first state S1 in response to the elastic force of the first elastic feature 48 and the second elastic feature 50, respectively, and the first working member 40 and the second working member 42 respectively block the two opposite ends of the blocking feature 32 of the first rail 26, namely the first end 32a and the second end 32b (e.g., the rear end and the front end), so as to prevent the second rail 28 from moving from the predetermined position P to the first predetermined direction D1 or the second predetermined direction D2.

[0026] like Figure 2 and Figure 3 As shown, when the operating member 38 is in the first operating position K1 (as shown in FIG. Figure 2 ), the working mechanism 34 is in the first state S1 corresponding to the blocking feature 32 of the first rail 26; when the operating member 38 is in a second operating position K2 (as shown in FIG. 1 ), the working mechanism 34 is in the first state S1 corresponding to the blocking feature 32 of the first rail 26; Figure 3As shown), the working mechanism 34 is in a second state S2 and does not correspond to the blocking feature 32 of the first rail 26.

[0027] Furthermore, when the operating member 38 is moved from the first operating position K1 (eg Figure 2 As shown in FIG. 1 , the user applies a force F to operate the second operating position K2 (as shown in FIG. 1 ). Figure 3 ), the working mechanism 34 is driven by the operating member 38 from the first state S1 (as shown in Figure 2 ) moves (e.g. pivots) to the second state S2 (e.g. Figure 3 ), so that the working mechanism 34 cannot block the blocking feature 32 of the first rail 26, so as to allow the second rail 28 to move from the predetermined position P to the first predetermined direction D1 or the second predetermined direction D2. For example, the second rail 28 can be removed from a channel 53 of the first rail 26 from the predetermined position P to the first predetermined direction D1; or, the second rail 28 can be retracted relative to the first rail 26 from the predetermined position P to the second predetermined direction D2. Among them, the first elastic feature 48 and the second elastic feature 50 are in a state of accumulating an elastic force (such as Figure 3 shown).

[0028] It should be noted that when the operating member 38 is in the second operating position K2, the operating member 38 and the latching member 36 can be latched with each other, so that the operating member 38 can still be maintained in the second operating position K2 when the force F is not applied, so as to maintain the working mechanism 34 in the second state S2, so that the working mechanism 34 can be maintained in a state where it cannot be blocked by the blocking feature 32 of the first rail 26 (such as Figure 3 Therefore, it is convenient for users to operate.

[0029] Furthermore, in an application environment where the plurality of slide rail assemblies 20 jointly carry the load 22, through the technical principle of the mutual locking or positioning of the operating member 38 and the locking member 36, the user can keep the operating member 38 of each slide rail assembly 20 at the second operating position K2 when the user stops applying the force F to the operating member 38 (in other words, the user does not need to continuously apply the force F to the operating member 38), so that the working mechanism 34 on the second rail 28 of each slide rail assembly 20 is kept in a state where it cannot block the blocking feature 32 of the first rail 26. Therefore, the user can directly remove the second rail 28 of each slide rail assembly 20 from the predetermined position P to the first predetermined direction D1 from the channel 53 of the first rail 26 (in other words, the load 22 can be directly removed from the rack 24); or, the second rail 28 of each slide rail assembly 20 can be directly retracted relative to the first rail 26 from the predetermined position P to the second predetermined direction D2, which is very convenient for the user in operation.

[0030] Preferably, the slide rail assembly 20 further includes a restoring elastic member 54 for providing elastic force to the operating member 38. When the operating member 38 is in the second operating position K2, the restoring elastic member 54 is in a state of accumulating a restoring elastic force J (eg, Figure 3 shown).

[0031] Preferably, the latching member 36 includes a latching portion 56, and the operating member 38 includes an auxiliary feature 58, wherein the latching portion 56 is, for example, a hole defined by a plurality of wall surfaces W, and the auxiliary feature 58 is, for example, a hook or a hook-shaped object, but the implementation is not limited thereto; when the operating member 38 is in the second operating position K2, the auxiliary feature 58 of the operating member 38 and the latching portion 56 of the latching member 36 are mutually engaged, so that the operating member 38 is maintained in the second operating position K2 (such as Figure 3 shown).

[0032] Preferably, one of the latching member 36 and the operating member 38 includes a guide portion. Here, the latching member 36 and the operating member 38 are respectively provided with a first guide portion 60 and a second guide portion 62, and the first guide portion 60 and the second guide portion 62 are inclined surfaces or arc surfaces. Further, when the operating member 38 moves from the first operating position K1 to the second operating position K2, the operating member 38 contacts the first guide portion 60 of the latching member 36 through the second guide portion 62, which helps to guide the auxiliary feature 58 of the operating member 38 to latch to the latching portion 56 of the latching member 36.

[0033] Preferably, the latching member 36 further includes an elastic arm 64, and the elastic arm 64 is provided with the latching portion 56; when the operating member 38 moves from the first operating position K1 to the second operating position K2, the operating member 38 contacts the first guide portion 60 of the latching member 36 through the second guide portion 62, thereby driving the elastic arm 64 to move in a height direction U (this part can be referred to Figure 2 The height direction U shown in the figure, for example, downward, causes the elastic arm 64 to accumulate an elastic force until the auxiliary feature 58 corresponds to the latching portion 56 of the latching member 36, and the elastic arm 64 releases the elastic force, causing the auxiliary feature 58 to latch to the latching portion 56 of the latching member 36 (such as Figure 3 shown).

[0034] Preferably, the latching member 36 is, for example, a spring. Specifically, the latching member 36 further includes a connecting portion 66 fixed to the second rail 28 , and the elastic arm 64 extends from the connecting portion 66 to a predetermined longitudinal length.

[0035] Preferably, the second rail 28 includes a first wall 25a, a second wall 25b and a longitudinal wall 27 connected between the first wall 25a and the second wall 25b of the second rail 28; the working mechanism 34 is disposed on the longitudinal wall 27 of the second rail 28; when the working mechanism 34 is in the first state S1, the working mechanism 34 approaches the first wall 25a of the second rail 28 (e.g., Figure 2 When the working mechanism 34 is in the second state S2, the working mechanism 34 is away from the first wall 25a of the second rail 28 (as shown); Figure 3 shown).

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the latch 36 further includes a release portion 68 corresponding to the blocking feature 32 of the first rail 26. The release portion 68 is, for example, an inclined surface or an arc surface. Preferably, the elastic arm 64 is provided with the release portion 68. When the second rail 28 is moved relative to the first rail 26 from the predetermined position P (such as Figure 3 When the first rail 26 is displaced in the second predetermined direction D2, the blocking feature 32 (the second end 32b) of the first rail 26 and the release portion 68 of the latch 36 contact each other (as shown in FIG. Figure 4 As shown) can generate a force, so that the elastic arm 64 of the latch 36 can swing to a predetermined angle in the height direction U (this part can refer to Figure 5 As shown, for example, the predetermined angle is deflected downward) to release the locking relationship between the auxiliary feature 58 of the operating member 38 and the locking portion 56 of the locking member 36. At this time, the reset elastic member 54 releases the reset elastic force J in the second predetermined direction D2, so that the operating member 38 can respond to the reset elastic force J from the second operating position K2 (as shown in FIG. Figure 4 As shown) returns to the first operating position K1 (as shown Figure 5 As shown), the first elastic feature 48 and the second elastic feature 50 release the elastic force, and the first working piece 40 and the second working piece 42 respectively respond to the first elastic feature 48 and the second elastic feature 50 releasing the elastic force and can be maintained in the first state S1 again (as shown). Figure 5 shown).

[0037] like Figure 6 and Figure 7 The second rail 200 of the slide rail assembly of the second embodiment of the present invention is shown. Similar to the first embodiment, the operating member 202 of the second embodiment is moved from the first operating position K1' (eg Figure 6 As shown) is moved to the second operating position K2' (as shown) by the user applying force F' Figure 7), the operating member 202 can engage with the latch member 204 to keep the operating member 202 in the second operating position K2', so as to keep the working mechanism 206 in the second state S2' (as shown in FIG. Figure 7 shown).

[0038] The difference between the second embodiment and the first embodiment essentially lies in the structural configuration and interactive relationship between the operating member 202 and the latching member 204 .

[0039] Further, the latching member 204 includes a connecting portion 208, an elastic arm 210, a latching portion 212 and a release portion 214. The connecting portion 208 is fixed to the second rail 200; the elastic arm 210 extends from the connecting portion 208 to a predetermined longitudinal length; the elastic arm 210 is provided with the latching portion 212 and the release portion 214. The latching portion 212 is, for example, a hook or a hook-shaped object, but the implementation is not limited thereto.

[0040] Preferably, the latching portion 212 of the latching member 204 is provided with an auxiliary guiding section 216 , and the auxiliary guiding section 216 is an inclined surface or an arc surface.

[0041] Preferably, the release portion 214 is an inclined surface or a curved surface.

[0042] On the other hand, the operating member 202 includes an auxiliary feature 218, and the auxiliary feature 218 is, for example, a vertical wall, but the implementation is not limited thereto; when the operating member 202 is in the second operating position K2', the auxiliary feature 218 of the operating member 202 is engaged with the engaging portion 212 of the engaging member 204, so that the operating member 202 is maintained in the second operating position K2' (such as Figure 7 shown).

[0043] Preferably, the operating member 202 includes a first space M1, and the latching portion 212 of the latching member 204 passes from a first side L1 of the operating member 202 to a second side L2 of the operating member 202, and the first side L1 and the second side L2 are opposite sides (such as Figure 6 shown).

[0044] The operating member 202 further includes a second space M2. The release portion 214 of the latching member 204 passes from the first side L1 of the operating member 202 to the second side L2 of the operating member 202 (eg, Figure 6 shown).

[0045] When the operating member 202 is moved from the first operating position K1' (eg Figure 6 As shown) is operated by the user applying the force F' to move to the second operating position K2' (as shown Figure 7), the working mechanism 206 (eg, the first working member 220 and the second working member 222) is driven by the operating member 202 to change from the first state S1' (eg, Figure 6 ) moves (eg pivots) to the second state S2' (eg Figure 7 As shown in the figure, according to this configuration, the working mechanism 206 can also be prevented from blocking the blocking feature 32 of the first rail 26, so as to allow the second rail 200 to move from the predetermined position P to the first predetermined direction D1 or the second predetermined direction D2. Since the technical principle of this part is the same as that of the first embodiment, it is not further described here for the sake of simplicity. Among them, the first elastic feature 224 and the second elastic feature 226 are in a state of accumulating an elastic force (such as Figure 7 shown).

[0046] It should be noted that when the operating member 202 is in the second operating position K2', the operating member 202 and the latching member 204 can be latched with each other, so that the operating member 202 can still be maintained in the second operating position K2' when the force F' is not applied, so as to maintain the working mechanism 206 in the second state S2', so that the working mechanism 206 can be maintained in a state where it cannot be blocked by the blocking feature 32 of the first rail 26 (such as Figure 7 Therefore, it is convenient for users to operate.

[0047] Preferably, when the operating member 202 is at the second operating position K2 ′, the auxiliary feature 218 of the operating member 202 and the latching portion 212 of the latching member 204 are latched with each other, so that the operating member 202 is maintained at the second operating position K2 ′.

[0048] Preferably, when the operating member 202 moves from the first operating position K1' to the second operating position K2', the auxiliary guide section 216 of the latch 204 contacts the operating member 202 (the inner wall 228 of the first space M1), thereby driving the elastic arm 210 to move in a lateral direction T (this part can be referred to Figure 6 The elastic arm 210 accumulates an elastic force until the auxiliary feature 218 corresponds to the latching portion 212 of the latching member 204, and the elastic arm 210 releases the elastic force, so that the auxiliary feature 218 of the operating member 202 and the latching portion 212 of the latching member 204 are latched with each other (as shown in FIG. Figure 7 shown).

[0049] It is worth mentioning that, similar to the technical principle of the first embodiment, the release portion 214 of the latching member 204 of the second embodiment is used to correspond to the blocking feature 32 (the second end 32b) of the first rail 26. When the second rail 200 is displaced from the predetermined position P to the second predetermined direction D2 relative to the first rail 26, a force can be generated by the contact between the blocking feature 32 (the second end 32b) of the first rail 26 and the release portion 214 of the latching member 204, so that the elastic arm 210 of the latching member 204 can be deflected to the horizontal direction T by a predetermined angle to release the locking relationship between the auxiliary feature 218 of the operating member 202 and the locking portion 212 of the latching member 204. At this time, the reset elastic member 230 releases the reset elastic force J' to the second predetermined direction D2, so that the operating member 202 can respond to the reset elastic force J' from the second operating position K2' (such as Figure 7 As shown) returns to the first operating position K1' (as shown Figure 6 ), the first elastic feature 224 and the second elastic feature 226 release the elastic force, and the working mechanism 206 (for example, the first working piece 220 and the second working piece 222) responds to the first elastic feature 224 and the second elastic feature 226 releasing the elastic force and can be maintained in the first state S1 (as shown) again. Figure 6 shown).

[0050] like Figure 8 and Fig. 9 The second rail 300 of the slide rail assembly of the third embodiment of the present invention is shown. Similar to the first embodiment, the operating member 302 of the third embodiment is moved from the first operating position K1 (eg, Figure 8 As shown) the user applies force F" to move to the second operating position K2 (as shown Fig. 9 ), the operating member 302 can engage with the latch member 304 to keep the operating member 302 in the second operating position K2", so as to keep the working mechanism 306 in the second state S2" (as shown in FIG. Fig. 9 shown).

[0051] The difference between the third embodiment and the first embodiment essentially lies in the structural configuration and interactive relationship between the operating member 302 and the latching member 304 .

[0052] Further, the latching member 304 includes a connecting portion 308, an elastic arm 310, a latching portion 312 and a release portion 314, and preferably, a supporting portion 315. The connecting portion 308 is movably mounted to the second rail 300. Here, the connecting portion 308 is pivotally connected to the second rail 300 via an auxiliary shaft 313 as an example; the elastic arm 310 extends from the top of the connecting portion 308 by a predetermined longitudinal length; the elastic arm 310 is provided with the latching portion 312 and the release portion 314; the supporting portion 315 extends from the bottom of the connecting portion 308 by a predetermined longitudinal length, and the supporting portion 315 and the elastic arm 310 are substantially parallel to each other. The supporting portion 315 can be used to support the second rail 300, and has the function of stabilizing the position of the latching member 304, and a predetermined spacing G (such as ) is defined between the supporting portion 315 and the connecting portion 308. Figure 8 shown).

[0053] Preferably, the latch portion 312 is, for example, a hole defined by a plurality of wall surfaces W", and the auxiliary feature 318 of the operating member 302 is, for example, a latch or a hook-shaped object, but the implementation is not limited thereto.

[0054] Preferably, the release portion 314 is an inclined surface or a curved surface.

[0055] Preferably, one of the latch member 304 and the operating member 302 includes a guide portion. Here, the latch member 304 and the operating member 302 are respectively provided with a first guide portion 320 and a second guide portion 322, and the first guide portion 320 and the second guide portion 322 are inclined surfaces or curved surfaces.

[0056] When the operating member 302 is in the second operating position K2", the auxiliary feature 318 of the operating member 302 and the latching portion 312 of the latching member 304 are latched with each other, so that the operating member 302 is maintained in the second operating position K2". Fig. 9 shown).

[0057] When the operating member 302 is moved from the first operating position K1" (such as Figure 8 As shown) the user applies the force F" to move to the second operating position K2 (as shown Fig. 9 ), the working mechanism 306 (for example, the first working member 320 and the second working member 322) is driven by the operating member 302 and changes from the first state S1 (as shown in FIG. Figure 8 (as shown) moves (e.g. pivots) to the second state S2" (as shown Fig. 9As shown in the figure, according to this configuration, the working mechanism 306 can also be prevented from blocking the blocking feature 32 of the first rail 26, so as to allow the second rail 300 to move from the predetermined position P to the first predetermined direction D1 or the second predetermined direction D2. Since the technical principle of this part is the same as that of the first embodiment, it is not further described here for the sake of simplicity. Among them, the first elastic feature 324 and the second elastic feature 326 are in a state of accumulating an elastic force (such as Fig. 9 shown).

[0058] It should be noted that when the operating member 302 is in the second operating position K2", the operating member 302 and the latching member 304 can be latched with each other, so that the operating member 302 can still be maintained in the second operating position K2" when the force F" is not applied, so as to maintain the working mechanism 306 in the second state S2", so that the working mechanism 306 can be maintained in a state where it cannot be blocked by the blocking feature 32 of the first rail 26 (such as Fig. 9 Therefore, it is convenient for users to operate.

[0059] Preferably, when the operating member 302 is at the second operating position K2", the auxiliary feature 318 of the operating member 302 and the latching portion 312 of the latching member 304 latch with each other, so that the operating member 302 is maintained at the second operating position K2".

[0060] Preferably, when the operating member 302 moves from the first operating position K1″ to the second operating position K2″, the operating member 302 contacts the first guide portion 320 of the latch member 304 through the second guide portion 322, thereby driving the elastic arm 310 to move in a height direction U” (refer to Figure 8 The auxiliary feature 318 is deflected in the height direction U", such as downward, thereby driving the connecting portion 308 of the latching member 304 to pivot toward the supporting portion 315 in a predetermined movable direction Q, which has a buffering effect and can prevent the latching member 304 from being deformed or damaged due to excessive force. The elastic arm 310 accumulates an elastic force until the auxiliary feature 318 corresponds to the latching portion 312 of the latching member 304. The elastic arm 310 releases the elastic force, so that the auxiliary feature 318 is latched to the latching portion 312 of the latching member 304 (such as Fig. 9 shown).

[0061] It is worth mentioning that, similar to the technical principle of the first embodiment, the release portion 314 of the latch 304 of the third embodiment is used to correspond to the blocking feature 32 (the second end 32b) of the first rail 26. When the second rail 300 is displaced from the predetermined position P to the second predetermined direction D2 relative to the first rail 26, a force can be generated by the contact between the blocking feature 32 (the second end 32b) of the first rail 26 and the release portion 314 of the latch 304, so that the elastic arm 310 of the latch 304 can be deflected to the height direction U" by a predetermined angle to release the locking relationship between the auxiliary feature 318 of the operating member 302 and the locking portion 312 of the latch 304. At this time, the reset elastic member 330 releases the reset elastic force J" toward the second predetermined direction D2, so that the operating member 302 can respond to the reset elastic force J" from the second operating position K2 (such as Fig. 9 (as shown) back to the first operating position K1" (as shown Figure 8 ), the first elastic feature 324 and the second elastic feature 326 release the elastic force, and the working mechanism 306 (for example, the first working piece 320 and the second working piece 322) responds to the first elastic feature 324 and the second elastic feature 326 releasing the elastic force and can be maintained in the first state S1 (as shown) again. Figure 8 shown).

[0062] It can be seen that the slide rail assembly 20 and the slide rail kit thereof according to the embodiment of the present invention include the following features:

[0063] 1. Different from the prior art in which the connecting rod does not have the function of being kept in a predetermined operating position after being operated by the user, when the operating member (38; 202; 302) of the first to third embodiments provided by the present invention is operated by the user from a first operating position (K1; K1'; K1") to a second operating position (K2; K2'; K2"), the latching member (36; 204; 304) and the operating member (38; 202; 302) can be latched with each other, so that the operating member (38; 202; 302) can be kept in the second operating position (K2; K2'; K2") K2; K2'; K2") is used to keep the working mechanism (34; 206; 306) in the second state (S2; S2'; S2"), thereby enabling the working mechanism (34; 206; 306) to be kept in a state where it cannot block the blocking feature 32 of the first rail 26, so that the second rail (28; 200; 300) can be removed from the predetermined position P toward the first predetermined direction D1 or folded toward the second predetermined direction D2 relative to the first rail 26, which is very convenient for a user to operate alone (single person).
