slide rail assembly

Abstract

This invention relates to a slide rail assembly, comprising a first rail, a second rail, an auxiliary component, a stop, and an operating component. The auxiliary component is arranged on the second rail. The stop is movably mounted to the second rail; when the second rail is in an extended position relative to the first rail, a blocking feature of the first rail can block the stop in a first state to prevent the second rail from displacing from the extended position in a retracting direction; the operating component, when operated to a position, can cause the stop to change from the first state to a second state, so that the blocking feature can no longer block the stop in the second state; the operating component is engaged with a predetermined portion of the auxiliary component to hold it in that position.

Description

Technical Field

[0001] This invention relates to a slide rail assembly, specifically an assembly in which, when the slide rail is unfolded, the obstruction between the middle and outer slide rails can be released first through an operating member, and the middle rail can be temporarily positioned to a predetermined location, while only the inner rail can be pulled out separately, thus facilitating use in confined spaces. Background Technology

[0002] For example, US Patent Publication No. 10,041,535B2 discloses a slide rail assembly comprising a first rail, a second rail, a third rail, a locking member, and an operating member. The second rail is movable relative to the first rail from a first position to a second position; the third rail is movable relative to the second rail; the locking member is mounted on the second rail and, when the second rail is in the second position, the locking member can lock a portion of the first rail, preventing the second rail from moving relative to the first rail from the second position to the first position; a user can apply a force to the operating member, causing the operating member to move relative to the second rail from a first predetermined position to a second predetermined position, thereby releasing the locking member from locking that portion of the first rail. When the operating component is moved from the first predetermined position to the second predetermined position by the user's application of force, it can be used to release the locking component from the first rail. However, the removal of the third rail from the second rail depends on the displacement of the second rail into the first rail. This method of operation is obviously not suitable for single-person operation, and even requires the use of a trolley to remove the chassis equipped with the third rail from the second rail in a confined space. Summary of the Invention

[0003] The purpose of this invention is to provide a slide rail assembly in which an obstruction mechanism is released by an operating element, allowing a slide rail to retract from an extended position relative to another slide rail.

[0004] According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, an auxiliary member, a stop member, and an operating member. The first rail is provided with a blocking feature; the second rail is displaceable relative to the first rail; the auxiliary member is arranged on the second rail, and the auxiliary member includes a resilient arm and a predetermined portion disposed on the resilient arm; the stop member is movably mounted to the second rail, such that the stop member can be in one of a first state and a second state relative to the second rail; the operating member is used to operate the stop member; wherein, when the second rail is in a first extended position relative to the first rail, the blocking feature can block the stop member in the first state to prevent the second rail from extending from the first extended position. The extension position is displaced in a retracting direction; wherein, the operation member can be operably moved from a first operating position to an opening direction to a second operating position, which can drive the stop member to change from the first state to the second state, so that the blocking feature cannot block the stop member in the second state, thereby allowing the second rail to be displaced from the first extension position to the retracting direction; wherein, when the operation member is in the second operating position, the operation member is locked onto the predetermined part of the auxiliary member by a locking feature, thereby holding the operation member in the second operating position.

[0026] like Figure 1 and Figure 2 As shown, a slide rail assembly 20 according to an embodiment of the present invention includes a first rail 22 and a second rail 24, and preferably, a third rail 26. The second rail 24 is movably mounted between the first rail 22 and the third rail 26. The first rail 22 (e.g., outer rail), the second rail 24 (e.g., middle rail), and the third rail 26 (e.g., inner rail) are longitudinally displaced relative to each other. When the slide rail assembly 20 is in a fully extended state, the second rail 24 is in a first extended position E1 relative to the first rail 22, and the third rail 26 is in an open position K relative to the second rail 24. It is worth mentioning that in this embodiment, the X-axis direction is longitudinal (or the length direction or displacement direction of the slide rail), the Y-axis direction is transverse (or the side direction of the slide rail), and the Z-axis direction is vertical (or the height direction of the slide rail).

[0027] The first track 22 includes a first wall 28a, a second wall 28b, and a longitudinal wall 30 connected between the first wall 28a and the second wall 28b of the first track 22. The first wall 28a, the second wall 28b, and the longitudinal wall 30 of the first track 22 together define a first channel for accommodating the second track 24. The first track 22 is provided with a blocking feature 32 (e.g., Figure 2 (As shown). Preferably, the first track 22 is further provided with a positioning feature 36 and a release feature 38.

[0028] Preferably, the first rail 22 has a front end portion 22a and a rear end portion 22b, and the release feature 38 is located adjacent to the rear end portion 22b of the first rail 22.

[0029] Preferably, the slide rail assembly 20 further includes a predetermined structure 40 arranged to the longitudinal wall 30 of the first rail 22. The predetermined structure 40 includes the blocking feature 32, a longitudinal portion 42 and a guide portion 44.

The longitudinal portion 42 is located between the blocking feature 32 and the guide portion 44, and the guide portion 44 is, for example, an inclined surface or an arc surface.

[0030] Preferably, the release feature 38 is, for example, a protrusion that protrudes laterally (or laterally) relative to the longitudinal wall 30 of the first track 22, and the release feature 38 includes a guide section 45, which is a slope (or an arc surface), but is not limited in implementation.

[0031] Preferably, the first track 22 further includes a first auxiliary portion 46 and a second auxiliary portion 48, and the positioning feature 36 is defined between the first auxiliary portion 46 and the second auxiliary portion 48. The first auxiliary portion 46 and the second auxiliary portion 48 are spaced apart from each other and are symmetrical to each other. The first auxiliary portion 46 and the second auxiliary portion 48 have substantially the same structural configuration. Taking the first auxiliary portion 46 as an example, the first auxiliary portion 46 is, for example, a protrusion that protrudes laterally (or transversely) relative to the longitudinal wall 30 of the first track 22.

[0032] Preferably, the first auxiliary part 46 and the second auxiliary part 48 each have a first guide structure 50 and a second guide structure 52, and the first guide structure 50 and the second guide structure 52 are inclined surfaces (or curved surfaces), but the implementation is not limited.

[0033] The second track 24 includes a first wall 54a, a second wall 54b, and a longitudinal wall 56 connected between the first wall 54a and the second wall 54b of the second track 24. The first wall 54a, the second wall 54b, and the longitudinal wall 56 of the second track 24 together define a second channel for accommodating the third track 26. The second track 24 has a first side L1 and a second side L2 that are opposite to each other. The first side L1 is adjacent to the first track 22, and the second side L2 is adjacent to the third track 26.

[0034] The slide rail assembly 20 also includes an auxiliary component 57, a stop component 58, and an operating component 60. Preferably, it also includes a positioning component 62 and a return elastic component 64. The stop component 58 and the positioning component 62 are both movably mounted to the second rail 24. Here, it is taken as an example that the stop component 58 and the positioning component 62 are pivotally connected to the second side L2 of the longitudinal wall 56 of the second rail 24 through a shaft 66, but the implementation is not limited to this.

[0035] Preferably, the second rail 24 includes at least one hole connecting a first side L1 and a second side L2 of the longitudinal wall 56 of the second rail 24. Here, a first hole H1 and a second hole H2 are used as an example. Furthermore, the auxiliary member 57 is arranged on the second rail 24 and is used in conjunction with the operating member 60; the stop member 58 includes a stop portion 68 that passes through the first hole H1, the stop portion 68 facing the longitudinal wall 30 of the first rail 22, and the stop portion 68 is used in conjunction with the blocking feature 32 of the first rail 22; on the other hand, the positioning member 62 includes a positioning portion 70 that passes through the second hole H2, the positioning portion 70 facing the longitudinal wall 30 of the first rail 22, and the positioning portion 70 is used in conjunction with the positioning feature 36 of the first rail 22.

[0036] Preferably, the slide rail assembly 20 further includes a predetermined element 72 connected to the longitudinal wall 56 of the second rail 24, and the predetermined element 72 includes a first elastic feature 74 and a second elastic feature 76 for providing elastic force to the stop 58 and the positioning member 62, respectively. The predetermined element 72 is, for example, a spring sheet or a component with elastic capacity, and the first elastic feature 74 and the second elastic feature 76 are two arms, but the implementation is not limited.

[0037] The operating element 60 is movably mounted to the second rail 24, and the operating element 60 is used to operate one of the stop 58 and the positioning element 62.

[0038] Preferably, the operating member 60 is arranged on the longitudinal wall 56 of the second rail 24, and the operating member 60 includes an operating part 78, a driving part 80, and an extension part 82 connected between the operating part 78 and the driving part 80. The second rail 24 has a front end portion 24a and a rear end portion 24b. The operating part 78 is located adjacent to the front end portion 24a of the second rail 24.

[0039] Preferably, the operating part 78 and the driving part 80 are located at a front end 82a and a rear end 82b adjacent to the extension 82, respectively.

[0040] Preferably, the second rail 24 includes a through hole 81 connecting the first side L1 and the second side L2 of the second rail 24, and the operating part 78 has a corresponding space 83 corresponding to the through hole 81, the through hole 81 being slightly larger than the corresponding space 83. The corresponding space 83 may, for example, allow a user's finger to be inserted to facilitate the user applying force to the operating part 78, but the implementation is not limited to this.

[0041] Preferably, the drive unit 80 is located adjacent to the stop 58 and the positioning member 62.

[0042] Preferably, the second rail 24 and the operating member 60, through their mutually matching structural features, allow the operating member 60 to move longitudinally relative to the second rail 24 within a limited range. Here, the second rail 24 and the operating member 60 are mutually restrained through the mutual matching of at least one mounting feature (e.g., first mounting feature 84a and second mounting feature 84b) and at least one connecting feature (e.g., first connecting feature 86a and second connecting feature 86b). Furthermore, the mounting features 84a and 84b and the connecting features 86a and 86b can be a combination of a connector (a nail-like object or protrusion) and an elongated hole. For example, the connector passes through a portion of the elongated hole to movably mount the operating member 60 to the longitudinal wall 56 of the second rail 24, allowing the operating member 60 to move longitudinally only within a limited range relative to the second rail 24, but the implementation is not limited.

[0043] The restoring elastic element 64 is used to provide a restoring elastic force to the operating element 60. Here, taking as an example a first predetermined segment 55 of the operating element 60 and a second predetermined segment 77 of the second rail 24 connected at both ends of the restoring elastic element 64 (e.g., Figure 1 (as shown), but its implementation is not limited.

[0044] Preferably, the operating element 60 is provided with a latching feature 88 (this part can be referred to in conjunction with other information). Figure 4 As shown, the latch feature 88 is arranged in the drive unit 80 as an example, but the implementation is not limited to this.

[0045] Preferably, the latching feature 88 is, for example, a hook, and the latching feature 88 has a guide surface 96, such as a bevel or an arc surface (this part can be referred to in conjunction with the previous text). Figure 4 (As shown).

[0046] like Figures 3 to 5 As shown, the stop 58 and the positioning member 62 are located near the rear end 24b of the second rail 24. The drive portion 80 and the extension portion 82 of the operating member 60 are located on opposite sides of the second rail 24. For example, the drive portion 80 of the operating member 60 can be an additional component located on the second side L2 of the second rail 24 (e.g., Figure 3 and Figure 4 As shown), and a fastener 97 passes from the second side L2 of the second rail 24 to the first side L1 of the second rail 24 to fix the drive part 80 of the operating member 60 to the rear end 82b of the extension 82 of the operating member 60 located on the first side L1 of the second rail 24 (as shown). Figure 5 As shown), and the fastener 97 corresponds to (or passes through) a portion of a limiting hole 95 in the second rail 24 (as shown). Figure 4(As shown), however, the implementation of the operating member 60 is not limited to this. Both the stop member 58 and the positioning member 62 can be in a first state S1 relative to the second rail 24 (as shown). Figure 4 (As shown). On the other hand, the operating element 60 can be in a first operating position P1 relative to the second rail 24.

[0047] Furthermore, the auxiliary component 57 includes a flexible arm 98 and a predetermined portion 100 disposed on the flexible arm 98. Preferably, the auxiliary component 57 also includes a mounting portion 102 connected to the first side L1 of the second rail 24 (e.g., Figure 5 As shown), the elastic arm 98 extends from the mounting portion 102, and the predetermined portion 100 passes through a predetermined hole 104 in the second rail 24 from the first side L1 to the second side L2 of the second rail 24 (as shown). Figure 4 and Figure 5 As shown), the predetermined part 100 is used in conjunction with the latching feature 88 of the operating member 60.

[0048] Preferably, the predetermined part 100 has another guide surface 106 (e.g., a slope or an arc surface) corresponding to the guide surface 96 of the latching feature 88.

[0049] Preferably, the stop 58 further includes a contact portion 108, and the shaft 66 is located between the stop portion 68 and the contact portion 108 of the stop 58. The contact portion 108 corresponds to (or contacts) a first drive segment 110 of the drive portion 80 of the operating member 60 (e.g., ...). Figure 4 (as shown); and the first elastic feature 74 provides elastic force to the stop 58 (the stop portion 68), the stop 58 being held in the first state S1 (as shown). Figure 4 As shown), the stop portion 68 of the stop 58 is brought close to (or toward) the longitudinal wall 30 of the first rail 22.

[0050] Preferably, the positioning member 62 further includes a contact segment 112, and the shaft member 66 is located between the positioning portion 70 of the positioning member 62 and the contact segment 112. The contact segment 112 corresponds to (or contacts) a second drive segment 114 of the drive portion 80 of the operating member 60 (e.g., ...). Figure 4 As shown), the second drive segment 114 and the first drive segment 110 are positioned correspondingly and have substantially the same structural configuration; and the second elastic feature 76 provides elastic force to the positioning member 62 (positioning portion 70), the positioning member 62 being held in the first state S1 (as shown). Figure 4 As shown), the positioning part 70 of the positioning member 62 is brought close to (or toward) the longitudinal wall 30 of the first track 22.

[0051] Preferably, the contact portion 108 of the stop 58 and one of the first drive segment 110 of the operating member 60 include a guiding feature, such as a ramp or arc surface, which facilitates the operating member 60 to drive the stop 58 through the first drive segment 110. Similarly, the contact portion 112 of the positioning member 62 and one of the second drive segment 114 of the operating member 60 include another guiding feature, such as a ramp or arc surface, which facilitates the operating member 60 to drive the positioning member 62 through the second drive segment 114.

[0052] like Figures 6 to 8 As shown, the user can apply a force F in an opening direction D1 to the operating part 78 of the operating member 60, such as... Figure 8 As shown), the operating member 60 can move relative to the second rail 24 from the first operating position P1 to the opening direction D1 to a second operating position P2. During this process, the operating member 60 contacts the contact portion 108 of the stop member 58 through the first driving section 110 of the driving part 80, thereby driving the stop member 58 to move from the first state S1 (e.g., lateral or sideways pivoting) to a second state S2, so that the stop portion 68 of the stop member 58 overcomes the elastic force of the first elastic feature 74 and moves away from the longitudinal wall 30 of the first rail 22 (e.g., as shown). Figure 7 (as shown); On the other hand, the operating member 60 contacts the contact section 112 of the positioning member 62 through the second driving section 114 of the driving part 80, so as to drive the positioning member 62 from the first state S1 (e.g., lateral or sideways pivoting) to a second state S2, so that the positioning part 70 of the positioning member 62 overcomes the elastic force of the second elastic feature 76 and moves away from the first track 22 (longitudinal wall 30) (as shown); Figure 7 (As shown).

[0053] When the operating member 60 is in the second operating position P2, the restoring elastic member 64 can accumulate the restoring elastic force F' to return to the first operating position P1 in a contraction direction D2 (e.g., Figure 8 As shown), and the operating member 60 is engaged with the predetermined portion 100 of the auxiliary member 57 via the locking feature 88 (as shown). Figure 7 As shown), it is used to hold the operating element 60 in the second operating position P2.

[0054] Preferably, when the operating element 60 is in the first operating position P1 (e.g., ... Figure 4 As shown) Move in the opening direction D1 to the second operating position P2 (as shown) Figure 7 During the process (as shown), the locking feature 88 can contact another guide surface 106 of the predetermined part 100 through the guide surface 96, which helps to guide the locking feature 88 of the operating member 60 to a stop section 115 that locks onto the predetermined part 100 of the auxiliary member 57 (as shown). Figure 7 (As shown).

[0055] Preferably, when the operating member 60 is in the second operating position P2, the operating member 60 presses against the contact portion 108 of the stop member 58 and the contact portion 112 of the positioning member 62 through the first drive section 110 and the second drive section 114 respectively, so as to hold the stop member 58 and the positioning member 62 in the second state S2 (e.g., Figure 7 (As shown).

[0056] like Figure 9 As shown, the slide rail assembly 20 is mounted to a frame 116, and the slide rail assembly 20 is in its fully extended state. The first rail 22 is mounted (fixed) to the frame 116, and the third rail 26 can be used to support a load (not shown), allowing the load to be moved from inside the frame 116 to outside the frame 116 via the third rail 26. The frame 116 has a front end 116a and a rear end 116b. The operating part 78 extends beyond the front end 116a of the frame 116 by a predetermined longitudinal distance for easy user operation.

[0057] like Figure 10 As shown, the slide rail assembly 20 is in the fully extended state. The second rail 24 is in the first extended position E1 relative to the first rail 22, and the third rail 26 is in the open position K relative to the second rail 24. It is worth noting that when the second rail 24 is in the first extended position E1 relative to the first rail 22, the slide rail assembly 20 has a first length J1, such that the front end 26a of the third rail 26 has only a first distance X1 between it and an object 122 (e.g., a door or obstacle). Because this first distance X1 is too narrow, the third rail 26 cannot be unloaded from the second channel of the second rail 24 in the opening direction D1. When the second rail 24 is in the first extended position E1 relative to the first rail 22, the blocking feature 32 can block the stop portion 68 of the stop member 58 in the first state S1, preventing the second rail 24 from displacing from the first extended position E1 towards the closing direction D2. On the other hand, the positioning member 62 contacts the longitudinal wall 30 of the first rail 22 through the positioning part 70. Furthermore, the operating member 60 is in the first operating position P1, and the restoring elastic member 64 is in a state where the restoring elastic force has not yet accumulated (this part can be referred to in conjunction with...). Figure 3 or Figure 5 Furthermore, the locking feature 88 of the operating component 60 has not yet locked onto the predetermined portion 100 of the auxiliary component 57 (this part can also be referred to in conjunction with this). Figure 4 (As shown).

[0058] like Figure 10 and Figure 11As shown, the user can apply the force F in the opening direction D1 to the operating part 78 of the operating member 60, causing the operating member 60 to move from the first operating position P1 to the second operating position P2 in the opening direction D1. Furthermore, the first driving section 110 of the driving part 80 can drive the stop 58 from the first state S1 (e.g., ...). Figure 10 As shown, it transforms into the second state S2 (as shown). Figure 11 As shown), the blocking feature 32 prevents the stop portion 68 of the stop member 58 in the second state S2 from obstructing it, thereby allowing the second rail 24 to move relative to the first rail 22 from the first extension position E1 toward the retraction direction D2. On the other hand, during the process of the operating member 60 moving from the first operating position P1 to the second operating position P2, the second driving section 114 of the driving part 80 (due to the viewing angle) Figure 10 and Figure 11 The second drive segment 114 (not shown) contacts the contact segment 112 of the positioning member 62 to drive the positioning member 62 from the first state S1 (e.g., Figure 10 As shown, it transforms into the second state S2 (as shown). Figure 11 As shown), the positioning part 70 of the positioning member 62 is raised at an angle relative to the longitudinal wall 30 of the first rail 22, thus laterally offset from the positioning feature 36. When the stop member 58 and the positioning member 62 are in the second state S2, the first elastic feature 74 and the second elastic feature 76 are respectively in a state of accumulated elastic force (this part can also be referred to in conjunction with the previous section). Figure 7 (As shown). Furthermore, when the operating member 60 is in the second operating position P2, the restoring elastic member 64 is in a state of accumulating the restoring elastic force F' (this part can also be referred to). Figure 8 As shown), the operating member 60 is engaged with the stop section 115 of the predetermined part 100 of the auxiliary member 57 via the locking feature 88 (this part can be referred to in conjunction with the reference). Figure 7 As shown), this is used to hold the operating element 60 in the second operating position P2 (this part can also be referred to in conjunction with the following). Figure 8 (As shown).

[0059] like Figure 12 As shown, the operating member 60 is engaged with the stop section 115 of the predetermined part 100 of the auxiliary member 57 by the locking feature 88, so as to keep the operating member 60 in the second operating position P2, and the restoring elastic member 64 is kept in the state of accumulating the restoring elastic force F' in the closing direction D2.

[0060] like Figure 12 and Figure 13 As shown, once the latching feature 88 is no longer latched onto the predetermined portion 100 of the auxiliary member 57 (e.g., Figure 13As shown), the restoring elasticity 64 provides the restoring elastic force F' to the operating member 60, enabling the operating member 60 to move from the second operating position P2 (as shown). Figure 12 (As shown) Return to the first operation position P1 (as shown) Figure 13 (As shown). Furthermore, during the process of the second rail 24 moving relative to the first rail 22 from the first extension position E1 towards the retraction direction D2 to a retraction position R, because the positioning part 70 of the positioning member 62 in the second state S2 is raised relative to the longitudinal wall 30 of the first rail 22 and laterally offset from the positioning feature 36, the positioning member 62 can directly pass over the positioning feature 36 of the first rail 22 in the retraction direction D2 (in other words, the positioning part 70 of the positioning member 62 will not be stuck to the positioning feature 36, as shown). Figure 12 As shown), furthermore, when the second rail 24 is displaced in the retraction direction D2 to a predetermined stroke, the predetermined portion 100 (guide surface 106) of the auxiliary member 57 comes into contact with the release feature 38 (guide section 45) of the first rail 22, thereby allowing the elastic arm 98 of the auxiliary member 57 to be driven in a predetermined direction U (e.g., Figure 13 As shown), the locking feature 88 of the operating member 60 is disengaged from the stop section 115 of the predetermined portion 100 of the auxiliary member 57, so that the operating member 60 can respond to the return elastic member 64 releasing the return elastic force F' in the retraction direction D2 and can move from the second operating position P2 (as shown). Figure 12 (As shown) Return to the first operation position P1 (as shown) Figure 13 (As shown). Furthermore, when the operating member 60 is in the first operating position P1, the stop member 58 and the positioning member 62 respond to the first elastic feature 74 and the second elastic feature 76 respectively, releasing elastic force to return from the second state S2 to the first state S1 (as shown). Figure 13 As shown, this section can also be consulted. Figure 4 ).

[0061] Preferably, the first rail 22 further includes at least one blocking structure 124, which is, for example, a protrusion, but is not limited in implementation. When the second rail 24 is in the retracted position R relative to the first rail 22 (e.g. Figure 13 As shown, the blocking structure 124 is used to block the rear end 24b of the second rail 24, preventing the second rail 24 from continuing to displace in the retracting direction D2. The retracting position R is, for example, the fully retracted position.

[0062] like Figure 14 and Figure 15 As shown, when the second rail 24 moves from the retracted position R to the opening direction D1 to a second extended position E2, the positioning member 62, which is in the first state S1, can engage the positioning feature 36 (e.g., Figure 15As shown), it is used to prevent the second rail 24 from shifting relative to the first rail 22 from the second extension position E2 toward the closing direction D2 or the opening direction D1.

[0063] Furthermore, as the second rail 24 moves from the retracted position R to the opening direction D1 to the second extended position E2, the positioning portion 70 of the positioning member 62 in the first state S1 will contact the second guide structure 52 of the second auxiliary portion 48 (e.g., Figure 14 As shown), this helps guide the positioning portion 70 of the positioning member 62 to the positioning feature 36 until the second rail 24 reaches the second extended position E2. In the first state S1, the positioning portion 70 of the positioning member 62 is engaged with the positioning feature 36 of the first rail 22. For example, the positioning portion 70 of the positioning member 62 is blocked between the first auxiliary portion 46 and the second auxiliary portion 48 to prevent the second rail 24 from displacing relative to the first rail 22 from the second extended position E2 toward the retracting direction D2 or the opening direction D1 (e.g.). Figure 15 (As shown).

[0064] like Figure 15 and Figure 16 As shown, when the second rail 24 is in the second extended position E2 relative to the first rail 22, the slide rail assembly 20 has a second length J2 that is smaller than the first length J1, such that the front end 26a of the third rail 26 has a second distance X2 that is greater than the first distance X1 between it and the object 122. Therefore, it is advantageous for the third rail 26 to be unloaded from the second channel of the second rail 24 in the opening direction D1 (e.g., Figure 16 (As shown).

[0065] like Figure 17 and Figure 18 As shown, if the user wishes to move the second rail 24 relative to the first rail 22 from the second extension position E2 toward the retracting direction D2 to the retracting position R, or to move the second rail 24 relative to the first rail 22 from the second extension position E2 toward the opening direction D1 to the first extension position E1, the user can move the third rail 26 from, for example, the opening position K toward the retracting direction D2 until the third rail 26 (for example, the rear end 26b, but not limited to) contacts the contact segment 112 of the positioning member 62, such as... Figure 17 As shown), this is used to drive the positioning member 62, so that the positioning part 70 of the positioning member 62 is no longer in the first state S1, causing the positioning part 70 of the positioning member 62 to disengage from the positioning feature 36 (as shown). Figure 18As shown), it is used to allow the second rail 24 to move relative to the first rail 22 from the second extension position E2 toward the retracting direction D2 until the slide rail assembly 20 is in a fully retracted state; or, to allow the second rail 24 to move relative to the first rail 22 from the second extension position E2 toward the opening direction D1.

[0066] Preferably, the third rail 26 (or a predetermined feature on the third rail 26, such as a protrusion) contacts the contact portion 108 of the stop 58, so that the stop portion 68 of the stop 58 is no longer in the first state S1 (e.g., Figure 18 (As shown).

[0067] like Figures 19 to 20 As shown, when the second rail 24 is in the second extended position E2 relative to the first rail 22, in addition to the third rail 26 being used to release the locking relationship between the second rail 24 and the first rail 22 (for example...), Figure 17 and Figure 18 In this embodiment, the user can also directly release the locking relationship between the second rail 24 and the first rail 22 through the operating member 60. Furthermore, when the second rail 24 is in the second extended position E2 relative to the first rail 22, the user can apply the force F in the opening direction D1 to the operating member 60, causing the operating member 60 to move from the first operating position P1 to the second operating position P2 in the opening direction D1. The second driving section 114 of the driving part 80 can drive the positioning member 62 to change from the first state S1 to the second state S2, so that the positioning part 70 of the positioning member 62 is released from the positioning feature 36 of the first rail 22, thereby allowing the second rail 24 to move relative to the first rail 22 from the second extended position E2 in the closing direction D2 or the opening direction D1. When the operating member 60 is in the second operating position P2, the operating member 60 is engaged with the predetermined portion 100 of the auxiliary member 57 by the locking feature 88, thereby holding the operating member 60 in the second operating position P2 (this part can also be referred to). Figure 7 ).

[0068] The slide rail assembly 20 of this invention includes the following features:

[0069] 1. The operating member 60 is engaged with the predetermined portion 100 of the elastic arm 98 of the auxiliary member 57 via the locking feature 88, thereby holding the operating member 60 in the second operating position P2; once the locking feature 88 is no longer engaged with the predetermined portion 100 of the auxiliary member 57, the return elastic member 64 provides a return elastic force F' to allow the operating member 60 to return from the second operating position P2 to the first operating position P1. Furthermore, the operating direction of the operating member 60 is towards the opening direction D1, allowing the user to operate (pull forward) the operating member 60 more intuitively via the operating part 78.

[0070] 2. The stop 58 and the positioning member 62 share the same shaft 66, and the shaft 66 is configured in the height direction of the slide rail, so that the pivoting direction of the stop 58 and the positioning member 62 is lateral (or sideways).

[0071] Although the present invention has been described with reference to specific embodiments, those skilled in the art should recognize that the above embodiments are merely illustrative of the invention, and various equivalent changes and modifications can be made without departing from the spirit of the invention. Therefore, any changes or modifications to the above embodiments within the scope of the essential spirit of the invention will fall within the scope of the claims of this application.
