Slide rail assembly

Abstract

The invention relates to a sliding rail assembly. The sliding rail assembly comprises a first rail, a second rail, an auxiliary piece, a blocking piece and an operating piece. The auxiliary member is arranged on the second rail. The blocking piece is movably installed on the second rail. When the second rail is located at an extending position relative to the first rail, a blocking feature of the first rail can block the blocking piece in a first state, and the blocking piece is used for preventing the second rail from moving from the extending position to a folding direction. When the operating piece is operated to be at a position, the blocking piece can be driven to be converted from the first state to a second state, so that the blocking characteristic cannot block the blocking piece in the second state; and the operating piece is clamped at a preset part of the auxiliary piece to be kept at the position.

Description

Technical Field

[0001] The present invention relates to a slide rail assembly, and more particularly to a slide rail assembly which can release the blocking relationship between the middle and outer slide rails through an operating member when the slide rails are unfolded, and then retract the middle rail to a predetermined position for temporary positioning, so that only the inner rail can be pulled out separately, so as to facilitate use in a narrow space environment. Background Art

[0002] For example, US Patent Publication No. US10,041,535B2 discloses a slide rail assembly, which includes a first rail, a second rail, a third rail, a locking member, and an operating member. The second rail can move from a first position to a second position relative to the first rail; the third rail can move relative to the second rail; the locking member is installed 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, so that the second rail cannot move from the second position to the first position relative to the first rail; a user can apply a force to the operating member to move the operating member from a first predetermined position to a second predetermined position relative to the second rail, so as to release the locking member from locking the portion of the first rail. When the operating member is displaced from the first predetermined position to the second predetermined position by the user, it can be used to release the lock of the locking member on the portion of the first rail. However, the removal of the third rail from the second rail requires the cooperation of the displacement of the second rail into the first rail. This operation method is obviously not conducive to 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 narrow space. Summary of the invention

[0003] The object of the present invention is to provide a slide rail assembly which can release a blocking mechanism through an operating member so that a slide rail can be retracted 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 stopper, and an operating member. The first rail is provided with a blocking feature; the second rail can be displaced relative to the first rail; the auxiliary member is arranged on the second rail, and the auxiliary member includes an elastic arm and a predetermined portion arranged on the elastic arm; the stopper is movably mounted to the second rail so that the stopper 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 stopper; wherein, when the second rail is in a first extended position relative to the first rail, the blocking feature can block the stopper in the first state to prevent the second rail from moving from the first extended position. The second rail is displaced from the first extended position to a retracted direction; wherein, the operating member can be operably moved from a first operating position to an open direction to a second operating position to drive the blocking member to be converted from the first state to the second state, so that the blocking feature cannot block the blocking member in the second state, so as to allow the second rail to be displaced from the first extended position to the retracted direction; wherein, when the operating member is in the second operating position, the operating member is engaged with the predetermined portion of the auxiliary member through a latch feature to keep the operating member in the second operating position.

The stopper 58 and the positioning member 62 are both movably mounted to the second rail 24. Here, the stopper 58 and the positioning member 62 are pivotally connected to the second side L2 of the longitudinal wall 56 of the second rail 24 through a shaft member 66 as an example, but the implementation is not limited thereto.

The predetermined object 72 is, for example, a spring or a member with elasticity, and the first elastic feature 74 and the second elastic feature 76 are two arms, but the implementation is not limited thereto.

[0037] The operating member 60 is movably mounted to the second rail 24 , and the operating member 60 is used to operate one of the stopper 58 and the positioning member 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 portion 78, a driving portion 80 and an extending portion 82 connected between the operating portion 78 and the driving portion 80. The second rail 24 has a front end portion 24a and a rear end portion 24b. The operating portion 78 is located adjacent to the front end portion 24a of the second rail 24.

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

[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 portion 78 has a corresponding space 83 corresponding to the through hole 81, and the size of the through hole 81 is slightly larger than the corresponding space 83. The corresponding space 83 can be provided for the user's finger to penetrate, so as to facilitate the user to apply force to the operating portion 78, but the implementation is not limited thereto.

[0041] Preferably, the driving portion 80 is located adjacent to the stopper 58 and the positioning member 62 .

[0042] Preferably, the second rail 24 and the operating member 60 have mutually matched structural features, so that the operating member 60 can move longitudinally within a limited range relative to the second rail 24. Here, the second rail 24 and the operating member 60 can be mutually limited by the mutual matching of at least one mounting feature (e.g., the first mounting feature 84a and the second mounting feature 84b) and at least one connecting feature (e.g., the first connecting feature 86a and the second connecting feature 86b). Further, the mounting features 84a, 84b and the connecting features 86a, 86b can be a matching of a connecting member (a nail or a protrusion) and a long hole. For example, the connecting member passes through a portion of the long hole to movably mount the operating member 60 to the longitudinal wall 56 of the second rail 24, and the operating member 60 can only move longitudinally within a limited range relative to the second rail 24, but the implementation is not limited thereto.

[0043] The return elastic member 64 is used to provide a return elastic force to the operating member 60. Here, the two ends of the return elastic member 64 are respectively connected to a first predetermined section 55 of the operating member 60 and a second predetermined section 77 of the second rail 24 as an example (eg Figure 1 ), but is not limited in implementation.

[0044] Preferably, the operating member 60 is provided with a latch feature 88 (this part can be referred to in conjunction with Figure 4 As shown), here, the latch feature 88 is arranged on the driving portion 80 as an example, but the implementation is not limited thereto.

[0045] Preferably, the latch feature 88 is, for example, a hook, and the latch feature 88 has a guide surface 96, such as an inclined surface or an arc surface (this part can be combined with reference to Figure 4 shown).

[0046] like Figures 3 to 5 As shown in FIG. 5 , the stopper 58 and the positioning member 62 are located near the rear end portion 24b of the second rail 24. The driving portion 80 of the operating member 60 and the extending portion 82 of the operating member 60 are respectively located on both sides of the second rail 24. For example, the driving portion 80 of the operating member 60 can be an additional component and located on the second side L2 of the second rail 24 (e.g., Figure 3 and Figure 4 ), and through a fixing member 97 passing from the second side L2 of the second rail 24 to the first side L1 of the second rail 24, the driving portion 80 of the operating member 60 is fixed to the rear end 82b (as shown) of the extension portion 82 of the operating member 60 located on the first side L1 of the second rail 24. Figure 5 As shown), the fixing member 97 corresponds to (or passes through) a portion of a limiting hole 95 of the second rail 24 (as shown Figure 4However, the implementation of the operating member 60 is not limited thereto. The stopper 58 and the positioning member 62 can both be in a first state S1 relative to the second rail 24 (as shown in FIG. 2 ). Figure 4 On the other hand, the operating member 60 can be located at a first operating position P1 relative to the second rail 24 .

[0047] Furthermore, the auxiliary member 57 includes an elastic arm 98 and a predetermined portion 100 disposed on the elastic arm 98. Preferably, the auxiliary member 57 further includes a mounting portion 102 connected to the first side L1 of the second rail 24 (eg, 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 of the second rail 24 from the first side L1 of the second rail 24 to the second side L2 of the second rail 24 (as shown in FIG. Figure 4 and Figure 5 As shown), wherein the predetermined portion 100 is used in conjunction with the latch feature 88 of the operating member 60.

[0048] Preferably, the predetermined portion 100 has another guiding surface 106 (such as an inclined surface or a curved surface) corresponding to the guiding surface 96 of the latching feature 88 .

[0049] Preferably, the stopper 58 further includes a contact portion 108, and the shaft member 66 is located between the stopper portion 68 of the stopper 58 and the contact portion 108. The contact portion 108 corresponds to (or contacts) a first driving section 110 (eg, Figure 4 and the first elastic feature 74 provides elastic force to the stopper 58 (stopper 68), the stopper 58 is maintained in the first state S1 (as shown); Figure 4 As shown), the stopper portion 68 of the stopper 58 is close to (or toward) the first rail 22 (the longitudinal wall 30).

[0050] Preferably, the positioning member 62 further includes a contact section 112, and the shaft member 66 is located between the positioning portion 70 of the positioning member 62 and the contact section 112. The contact section 112 corresponds to (or contacts) a second driving section 114 (such as Figure 4 ), wherein the second drive section 114 corresponds to the first drive section 110 in position and has substantially the same structural configuration; and the second elastic feature 76 provides elastic force to the positioning member 62 (the positioning portion 70), and the positioning member 62 remains in the first state S1 (as shown in FIG. Figure 4 As shown), the positioning portion 70 of the positioning member 62 is close to (or toward) the above-mentioned first rail 22 (the longitudinal wall 30).

[0051] Preferably, one of the contact portion 108 of the stopper 58 and the first driving section 110 of the operating member 60 includes a guiding feature, such as an inclined surface or a curved surface, which helps the operating member 60 drive the stopper 58 through the first driving section 110. Similarly, one of the contact section 112 of the positioning member 62 and the second driving section 114 of the operating member 60 includes another guiding feature, such as an inclined surface or a curved surface, which helps the operating member 60 drive the positioning member 62 through the second driving section 114.

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

[0053] When the operating member 60 is at the second operating position P2, the return elastic member 64 can accumulate the return elastic force F' (eg, Figure 8 ), and the operating member 60 is locked on the predetermined portion 100 (as shown) of the auxiliary member 57 through the locking feature 88. Figure 7 As shown), the operating member 60 is used to maintain the second operating position P2.

[0054] Preferably, when the operating member 60 is moved from the first operating position P1 (eg Figure 4 ) moves toward the opening direction D1 to the second operating position P2 (as shown Figure 7 During the process shown in FIG. 1 , the latching feature 88 can contact another guide surface 106 of the predetermined portion 100 through the guide surface 96, which helps to guide the latching feature 88 of the operating member 60 to a stopper 115 (such as FIG. 115 ) of the predetermined portion 100 that is latched on the auxiliary member 57. Figure 7 shown).

[0055] Preferably, when the operating member 60 is in the second operating position P2, the operating member 60 presses the contact portion 108 of the stopper 58 and the contact segment 112 of the positioning member 62 through the first driving segment 110 and the second driving segment 114, respectively, so as to keep the stopper 58 and the positioning member 62 in the second state S2 (such as Figure 7 shown).

[0056] like Fig. 9 As shown, the slide rail assembly 20 is mounted to a frame 116, and the slide rail assembly 20 is in the fully extended state. The first rail 22 is mounted (fixed) to the frame 116, and the third rail 26 can be used to carry a load (not shown), so that the load can be moved from the inside of the frame 116 to the outside of the frame 116 through the third rail 26. The frame 116 has a front end 116a and a rear end 116b. The operating portion 78 exceeds the front end 116a of the frame 116 by a predetermined longitudinal distance, which can be convenient for the user to operate.

[0057] like Fig.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 mentioning 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, so that there is only a first distance X1 between the front end 26a of the third rail 26 and an object 122 (such as a door or an obstacle). Since the first distance X1 is too narrow, the third rail 26 cannot be removed from the second channel of the second rail 24 in the open 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 blocking portion 68 of the blocking member 58 in the first state S1 to prevent the second rail 24 from moving from the first extended position E1 to the folded direction D2. On the other hand, the positioning member 62 contacts the longitudinal wall 30 of the first rail 22 through the positioning portion 70. In addition, the operating member 60 is in the first operating position P1, and the return elastic member 64 is in a state where the return elastic force has not yet accumulated (this part can be referred to in conjunction with Figure 3 or Figure 5 ), and the latching feature 88 of the operating member 60 has not yet latched to the predetermined portion 100 of the auxiliary member 57 (this part can also be referred to in conjunction with Figure 4 shown).

[0058] like Fig.10 and Fig.11As shown, the user can apply the force F in the opening direction D1 to the operating portion 78 of the operating member 60 to move the operating member 60 from the first operating position P1 to the opening direction D1 to the second operating position P2, and the first driving section 110 of the driving portion 80 can drive the blocking member 58 from the first state S1 (such as Fig.10 as shown) into the second state S2 (as shown Fig.11 As shown in FIG. 1 ), the blocking feature 32 cannot block the blocking portion 68 of the blocking member 58 in the second state S2, so as to allow the second rail 24 to move from the first extended position E1 to the folded direction D2 relative to the first rail 22. On the other hand, when the operating member 60 moves from the first operating position P1 to the second operating position P2, the second driving section 114 of the driving unit 80 (due to the viewing angle, Fig.10 and Fig.11 The second driving section 114 (not shown) contacts the contact section 112 of the positioning member 62 to drive the positioning member 62 from the first state S1 (such as Fig.10 as shown) into the second state S2 (as shown Fig.11 ), so that the positioning portion 70 of the positioning member 62 is lifted by an angle relative to the longitudinal wall 30 of the first rail 22 and is laterally staggered with the positioning feature 36. When the stopper 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 the state of accumulating elastic force (this part can also be referred to in conjunction with Figure 7 In addition, when the operating member 60 is in the second operating position P2, the return elastic member 64 is in a state of accumulating the return elastic force F' (this part can also be referred to in conjunction with Figure 8 As shown), the operating member 60 is locked in the stop section 115 of the predetermined portion 100 of the auxiliary member 57 through the locking feature 88 (this part can be used in conjunction with Figure 7 ), for maintaining the operating member 60 in the second operating position P2 (this part can also be referred to in conjunction with Figure 8 shown).

[0059] like Fig.12 As shown, the operating member 60 is locked to the stop section 115 of the predetermined portion 100 of the auxiliary member 57 through the locking feature 88 to maintain the operating member 60 in the second operating position P2, and the return elastic member 64 is kept in the state of accumulating the return elastic force F' toward the folding direction D2.

[0060] like Fig.12 and Fig.13 As shown, once the latch feature 88 is no longer latched on the predetermined portion 100 (such as Fig.13), the return elastic member 64 provides the return elastic force F' to the operating member 60, so that the operating member 60 can be moved from the second operating position P2 (as shown in FIG. Fig.12 As shown) back to the first operating position P1 (as shown Fig.13 ). Further, when the second rail 24 moves relative to the first rail 22 from the first extended position E1 to the folded direction D2 to a folded position R, since the positioning portion 70 of the positioning member 62 in the second state S2 is lifted relative to the longitudinal wall 30 of the first rail 22 and is 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 folded direction D2 (in other words, the positioning portion 70 of the positioning member 62 will not be caught by the positioning feature 36, as shown in FIG. 2 ). Fig.12 In addition, when the second rail 24 moves to a predetermined stroke in the folding direction D2, the predetermined portion 100 (the guide surface 106) of the auxiliary member 57 comes into contact with the release feature 38 (the guide section 45) of the first rail 22, and the elastic arm 98 of the auxiliary member 57 can be driven in a predetermined direction U (as shown in FIG. Fig.13 ), for releasing the latching feature 88 of the operating member 60 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 force F' released by the return elastic member 64 in the folding direction D2 and can move from the second operating position P2 (as shown in FIG. Fig.12 As shown) back to the first operating position P1 (as shown Fig.13 In addition, when the operating member 60 is in the first operating position P1, the stopper 58 and the positioning member 62 respectively respond to the first elastic feature 74 and the second elastic feature 76 to release the elastic force and return from the second state S2 to the first state S1 (as shown in FIG. Fig.13 This section can also be used in conjunction with Figure 4 ).

[0061] Preferably, the first rail 22 further includes at least one blocking structure 124, and the blocking structure 124 is, for example, a protrusion, but the implementation is not limited thereto. Fig.13 As shown in FIG. 1 , the blocking structure 124 is used to block the rear end portion 24b of the second rail 24 so that the second rail 24 cannot continue to move in the folding direction D2. The folding position R is, for example, a fully folded position.

[0062] like Fig.14 and Fig.15 As shown, when the second rail 24 moves from the folded position R to the opening direction D1 to a second extended position E2, the positioning member 62 in the first state S1 can be engaged with the positioning feature 36 (such as Fig.15), for preventing the second rail 24 from shifting from the second extension position E2 toward the folding direction D2 or the opening direction D1 relative to the first rail 22.

[0063] Furthermore, when the second rail 24 moves from the folded 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 contacts the second guide structure 52 of the second auxiliary portion 48 (eg, Fig.14 ), which helps the positioning portion 70 of the positioning member 62 to be guided to the positioning feature 36 until the second rail 24 reaches the second extended position E2. The positioning portion 70 of the positioning member 62 in the first state S1 is locked to 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 shifting relative to the first rail 22 from the second extended position E2 to the folding direction D2 or the opening direction D1 (as shown in FIG. Fig.15 shown).

[0064] like Fig.15 and Fig.16 As shown, when the second rail 24 is at 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, so that the second distance X2 between the front end 26a of the third rail 26 and the object 122 is larger than the first distance X1, thereby facilitating the third rail 26 to be removed from the second channel of the second rail 24 in the opening direction D1 (such as Fig.16 shown).

[0065] like Fig.17 and Fig.18 As shown, if the second rail 24 is to be displaced from the second extended position E2 to the folded direction D2 to the folded position R relative to the first rail 22, or if the second rail 24 is to be displaced from the second extended position E2 to the open direction D1 to the first extended position E1 relative to the first rail 22, the user can displace the third rail 26 from, for example, the open position K to the folded direction D2 until the third rail 26 (for example, the rear end portion 26b, but not limited thereto) contacts the contact segment 112 of the positioning member 62, as shown in FIG. Fig.17 ), to drive the positioning member 62 so that the positioning portion 70 of the positioning member 62 is no longer in the first state S1, so that the positioning portion 70 of the positioning member 62 is released from the positioning feature 36 (as shown in FIG. Fig.18As shown), the second rail 24 is used to allow the second rail 24 to move relative to the first rail 22 from the second extended position E2 to the folded direction D2 until the slide rail assembly 20 is in a fully folded state; or, the second rail 24 is used to allow the second rail 24 to move relative to the first rail 22 from the second extended position E2 to the open 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 stopper 58, so that the stopper 68 of the stopper 58 is no longer in the first state S1 (such as Fig.18 shown).

[0067] like Figures 19 to 20 As shown, when the second rail 24 is at the second extended position E2 relative to the first rail 22, in addition to releasing the locking relationship between the second rail 24 and the first rail 22 through the third rail 26 (for example Fig.17 and Fig.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. Further, when the second rail 24 is at 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, so that the operating member 60 moves from the first operating position P1 to the opening direction D1 to the second operating position P2, and the second driving section 114 of the driving unit 80 can drive the positioning member 62 to change from the first state S1 to the second state S2, so that the positioning portion 70 of the positioning member 62 is released from the positioning feature 36 of the first rail 22, so as to allow the second rail 24 to move from the second extended position E2 to the folding direction D2 or the opening direction D1 relative to the first rail 22. When the operating member 60 is at the second operating position P2, the operating member 60 is locked to the predetermined portion 100 of the auxiliary member 57 through the locking feature 88, so as to keep the operating member 60 at the second operating position P2 (this part can also be referred to in conjunction with Figure 7 ).

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

[0069] 1. The operating member 60 is locked to the predetermined portion 100 of the elastic arm 98 of the auxiliary member 57 through the locking feature 88 to keep the operating member 60 in the second operating position P2; once the locking feature 88 is no longer locked to the predetermined portion 100 of the auxiliary member 57, the operating member 60 can be returned to the first operating position P1 from the second operating position P2 through the return elastic member 64 to provide a return elastic force F'. In addition, the operating direction of the operating member 60 is toward the opening direction D1, and the user can more intuitively operate (pull forward) the operating member 60 through the operating portion 78.

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

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