Slide rail assembly

Abstract

The invention relates to a sliding rail assembly which comprises a first rail, a second rail, a third rail, a first working piece, a second working piece, an operating piece and a handle. When the handle moves from a first state to a second state, the operating piece is linked, and the second working piece moves from a first working state to a second working state accordingly. When the second rail moves to an extending position in an opening direction relative to the third rail, a first working piece in a first working state and a first retaining wall with a retaining characteristic on the third rail can be mutually blocked so as to prevent the second rail from continuously moving from the extending position to the opening direction; and on the other hand, the second working piece is in the second working state and cannot be mutually blocked with a second blocking wall with the blocking characteristic, so that the second rail is allowed to move from the extending position to a folding direction.

[0019] like Figure 1 and Figure 2 As shown, a slide rail assembly 20 of an embodiment of the present invention includes a first rail 22 (e.g., an outer rail), a second rail 24 (e.g., an inner rail), and a handle 26, and preferably, further includes a third rail 28 (e.g., a middle rail) movably installed between the first rail 22 and the second rail 24. The second rail 24 can be in a retracted position R relative to the first rail 22, and the second rail 24, the third rail 28 and the first rail 22 can be longitudinally displaced relative to each other. In this embodiment, the X-axis direction is the longitudinal direction (or the length direction or displacement direction of the slide rail), the Y-axis direction is the transverse direction (or the lateral direction of the slide rail), and the Z-axis direction is the vertical direction (or the height direction of the slide rail).

[0020] The first rail 22 has a first end 22a and a second end 22b that are opposite to each other, such as a front end and a rear end, but the implementation is not limited thereto; the first rail 22 includes a first wall 30a, a second wall 30b and a longitudinal wall 32 connected between the first wall 30a and the second wall 30b of the first rail 22. Preferably, the first rail 22 also includes a stopper 34, and here, the stopper 34 is taken as a protrusion protruding relative to the longitudinal wall 32 of the first rail 22, but the implementation is not limited thereto. The stopper 34 is arranged adjacent to the first end 22a of the first rail 22, wherein the stopper 34 has a stopper section 36 and a guide section 38 that are opposite to each other, the stopper section 36 is located at the rear end of the stopper section 34, the guide section 38 is located at the front end of the stopper section 34, and the guide section 38 is, for example, an inclined surface or an arc surface.

[0021] The third rail 28 has a first end 28a and a second end 28b opposite to each other, such as a front end and a rear end, but the implementation is not limited thereto; the third rail 28 includes a first wall 40a, a second wall 40b and a longitudinal wall 42 connected between the first wall 40a and the second wall 40b of the third rail 28. Preferably, the third rail 28 further includes a blocking feature 44, and here, the blocking feature 44 is taken as a protrusion protruding relative to the longitudinal wall 42 of the third rail 28, but the implementation is not limited thereto. The blocking feature 44 is arranged adjacent to the first end 28a of the third rail 28, wherein the blocking feature 44 has a first blocking wall 46 and a second blocking wall 48 opposite to each other, for example, the first blocking wall 46 is located at the rear end of the blocking feature 44, and the second blocking wall 48 is located at the front end of the blocking feature 44.

[0022] The second rail 24 has a first end 24a and a second end 24b that are opposite to each other, such as a front end and a rear end, but the implementation is not limited thereto; the second rail 24 includes a first wall 50a, a second wall 50b, and a longitudinal wall 52 connected between the first wall 50a and the second wall 50b of the second rail 24. Preferably, a shell 54 is connected (e.g., fixedly connected) to the second rail 24, so that the shell 54 can be regarded as a part of the second rail 24. The shell 54 includes a first shell portion 54a and a second shell portion 54b, which can be used to cover most of the related components and have a protective effect. Preferably, the shell 54 is adjacent to the first end 24a of the second rail 24.

[0023] like Figure 3 As shown, Figure 3 The shell 54 is omitted from illustration, and the related components arranged in the shell 54 include, for example, the handle 26 , an auxiliary component 56 , and an elastic feature 58 . Preferably, the related components further include a gear row component 60 , an actuator component 62 , and a shaft component 64 .

[0024] The handle 26 is pivotally connected to the second rail 24 via the shaft 64. Here, the shaft 64 is used to pivotally connect the handle 26 to the housing 54, but the implementation is not limited thereto. The configuration direction of the shaft 64 is substantially the same as the length direction of the second rail 24 or the displacement direction of the second rail 24 relative to the first rail 22, for example, both are longitudinal.

[0025] like Figure 2 and Figure 4 As shown, the auxiliary member 56 is arranged on the second rail 24, for example, the auxiliary member 56 is arranged on the housing 54 on the second rail 24. Preferably, the shaft member 64 is inserted into the auxiliary member 56 so that the auxiliary member 56 can move relative to the shaft member 64 (longitudinally), and the elastic feature 58 is used to provide elastic force to the auxiliary member 56; the elastic feature 58 is between the auxiliary member 56 and the housing 54.

[0026] Preferably, the gear row 60 is movable relative to the second rail 24, for example, the gear row 60 is movably mounted to the housing 54 on the second rail 24. Further, the gear row 60 is movable relative to the second rail 24 (housing 54) in the height direction. The handle 26 is provided with a gear feature 66 for intermeshing with the gear row 60.

[0027] Preferably, the actuator 62 is movable relative to the second rail 24 . For example, the actuator 62 is pivotally connected to the housing 54 on the second rail 24 via an axis 68 . The configuration direction of the axis 68 is substantially the same as the lateral direction of the second rail 24 .

[0028] Preferably, the slide rail assembly 20 further includes a driving member 70 that can move relative to the second rail 24, wherein the driving member 70 and the second rail 24 can move relative to each other within a limited range through the cooperation of a first limiting feature 72 and a second limiting feature 74. The first limiting feature 72 is, for example, a longitudinal long hole (or a long groove), and the second limiting feature 74 is, for example, a portion of a connecting member (or a connecting pin) passing through the longitudinal long hole.

[0029] Preferably, the slide rail assembly further includes an elastic member 76. Here, the elastic member 76 is connected between the driving member 70 and the second rail 24 as an example, but the implementation is not limited thereto. Further, two ends of the elastic member 76 are respectively connected to a mounting section 78 on the driving member 70 and the second limiting feature 74 on the second rail 24.

[0030] Preferably, the slide rail assembly 20 further includes a lock 80 movably mounted on the second rail 24. For example, the lock 80 is pivotally connected to at least one lug 84 on the second rail 24 through an auxiliary shaft 82. The configuration direction of the auxiliary shaft 82 is substantially the same as the height direction of the second rail 24.

[0031] Preferably, the lock element 80 and the drive element 70 have a first corresponding feature 86 and a second corresponding feature 88 that can match each other, and at least one of the first corresponding feature 86 and the second corresponding feature 88 is an inclined surface or an arc surface to facilitate relative displacement to generate an actuation relationship.

[0032] Preferably, the slide rail assembly 20 further comprises a first working piece 90, a second working piece 92 and an operating piece 94 movably mounted on the second rail 24. The first working piece 90 and the second working piece 92 are respectively pivotally connected to the second rail 24 (the longitudinal wall 52) through a first mounting shaft 96 and a second mounting shaft 98, wherein the slide rail assembly 20 further comprises at least one auxiliary elastic portion 99, wherein the first working piece 90 and the second working piece 92 can be maintained in a first working state S1 in response to the elastic force of a first elastic section 99a and a second elastic section 99b of the auxiliary elastic portion 99, respectively; the operating piece 94 is used to operate the second working piece 92; further, the operating piece 94 comprises a driving section 100, an operating section 102 and a longitudinal section 104 connected between the driving section 100 and the operating section 102. The driving section 100 corresponds to the second working member 92 . For example, the driving section 100 is used to operably connect to or drive the second working member 92 . On the other hand, the operating section 102 is connected to the driving member 70 , and the two have a linkage control relationship.

[0033] like Figure 3 and Figure 4 As shown, the auxiliary member 56 includes a latching feature 106, such as a protrusion or an extension, but the implementation is not limited thereto; the handle 26 is in a first state K1 relative to the second rail 24. On the other hand, when a force F is applied to the auxiliary member 56 or it is pressed against an object, such as the first rail 22, and is in a first auxiliary position C1, the elastic feature 58 accumulates a predetermined elastic force J. When the auxiliary member 56 is in the first auxiliary position C1, the position of the latching feature 106 of the auxiliary member 56 is a predetermined space M (such as 1 / 4 of the handle 26) corresponding to the first state K1. Figure 4 As shown), at this time, the handle 26 can be operated by the user to leave the first state K1.

[0034] like Figure 5 and Figure 6As shown, the handle 26 is operated (e.g., pulled) by the user and moves (e.g., pivots 90 degrees substantially) from the first state K1 to a second state K2. On the other hand, when the force F is no longer applied to the auxiliary member 56 or leaves the object it originally abuts, such as leaving the first rail 22, the elastic feature 58 releases the predetermined elastic force J to the auxiliary member 56, so that the auxiliary member 56 moves from the first auxiliary position C1 to a second auxiliary position C2 (e.g., the auxiliary member 56 moves toward the second end 24b of the second rail 24 to the second auxiliary position C2, but the implementation is not limited thereto), and the latching feature 106 of the auxiliary member 56 leaves the predetermined space M of the handle 26 and latches (or blocks) with a predetermined portion 108 of the handle 26. In other words, the latching feature 106 of the auxiliary member 56 blocks the moving path of the handle 26 from the second state K2 back to the first state K1, so as to keep the handle 26 in the second state K2.

[0035] For further information, please refer to Figure 3 and Figure 5 When the handle 26 is operated from the first state K1 (such as Figure 3 As shown) moves to the second state K2 (as shown Figure 5 During the process of the gear feature 66 of the handle 26 and the gear member 60, the handle 26 drives the actuating member 62 to pivot by an angle through the gear member 60, so that the actuating member 62 can push the driving member 70 from a first driving position N1 (as shown in FIG. Figure 3 The second rail 24 moves longitudinally (or linearly) toward the second end 24b of the second rail 24 to a second driving position N2 (as shown in FIG. Figure 5 As shown), the driving member 70 generates a force through the mutual contact between the first corresponding feature 86 and the second corresponding feature 88 to drive the lock member 80 from a locked state L1 (as shown in FIG. Figure 3 ) moves (e.g. pivots) to an unlocked state L2 (e.g. Figure 5 shown).

[0036] In addition, when the driving member 70 moves from the first driving position N1 to the second driving position N2, the driving member 70 drives the operating member 94 from a first operating position B1 (eg Figure 3 As shown) moves to a second operating position B2 (as shown Figure 5 ), for operating the second working member 92 from the first working state S1 (as shown Figure 3 As shown) moves to the second working state S2 (as shown Figure 5 As shown), the second elastic section 99b accumulates an elastic force (as shown Figure 5 shown).

[0037] It is worth mentioning that, since the handle 26, the gear member 60, the actuating member 62, the driving member 70, the locking member 80, the operating member 94 and the second working member 92 are in a linkage relationship, when the auxiliary member 56 is in the second auxiliary position C2, the handle 26 is kept in the second state K2 (such as when the auxiliary member 56 is in the second auxiliary position C2) by the locking feature 106 of the auxiliary member 56 and the predetermined portion 108 of the handle 26. Figure 6 As shown in FIG. 1 , the positions or states of the tooth row member 60, the actuating member 62, the driving member 70, the locking member 80, the operating member 94 and the second working member 92 are all maintained, and the elastic member 76 accumulates an elastic force Q (as shown in FIG. 1 ) in response to the driving member 70 being maintained at the second driving position N2. Figure 5 In other words, when the auxiliary member 56 is moved from the second auxiliary position C2 (as shown in FIG. Figure 5 As shown) back to the first auxiliary position C1 (as shown Figure 3 ), so that the latching feature 106 of the auxiliary member 56 is no longer latched with the predetermined portion 108 of the handle 26 (for example, the latching feature 106 of the auxiliary member 56 corresponds to the predetermined space M of the handle 26 again), the elastic member 76 releases the elastic force Q to allow the handle 26, the tooth row member 60, the actuating member 62, the driving member 70, the locking member 80, the operating member 94 and the second working member 92 to return to the initial position or state (as shown in FIG. Figure 3 shown).

[0038] like Figure 7 and Figure 8 As shown ( Figure 7 and Figure 8 The housing 54 is omitted from illustration. Preferably, the slide rail assembly 20 further includes an auxiliary elastic member 110, and the lock member 80 can be kept in the locked state L1 in response to the elastic force of an extension section 112 of the auxiliary elastic member 110. The slide rail assembly 20 is in a folded state, wherein the first rail 22 can be installed on a rack (or cabinet), and the second rail 24 can be used to carry a load. Since this part is a technical scope that can be understood by ordinary knowledgeable people familiar with the field, it is not further described here for the sake of simplicity.

[0039] Preferably, when the second rail 24 is in the retracted position R relative to the first rail 22, the locking portion 90 of the locking member 80 in the locked state L1 is used to lock (for example, abut) the blocking section 36 of the blocking portion 34 of the first rail 22 (see Figure 2), so as to prevent the second rail 24 from moving from the folded position R to an opening direction D1. In addition, the auxiliary member 56 abuts against a portion of the first rail 22 (for example, against the first end 22a of the first rail 22, but not limited thereto) to generate a force as the force F applied to the auxiliary member 56, so that the auxiliary member 56 is in the first auxiliary position C1, and the elastic feature 58 accumulates the predetermined elastic force J.

[0040] like Figures 7 to 10 As shown, when the handle 26 is operated by the user to move from the first state K1 to the second state K2, the second rail 24 is allowed to move from the retracted position R (as shown in FIG. Figure 7 and Figure 8 ) moves toward the opening direction D1 to a predetermined extended position P1 (as shown Fig. 9 and Fig.10 When the second rail 24 is at the predetermined extended position P1 relative to the first rail 22, the elastic feature 58 releases the predetermined elastic force J to the auxiliary member 56, so that the auxiliary member 56 moves from the first auxiliary position C1 (as shown in FIG. Figure 8 As shown) moves to the second auxiliary position C2 (as shown Fig.10 As shown), the latching feature 106 of the auxiliary member 56 can latch with (the predetermined portion 108 of) the handle 26 to maintain the handle 26 in the second state K2 (as shown). Fig. 9 and Fig.10 shown).

[0041] Preferably, in this embodiment, since the locking member 80 can lock the blocking portion 34 (the blocking section 36) in the locked state L1, if the second rail 24 is to be moved away from the retracted position R relative to the first rail 22, the user can operate (for example, pull) the handle 26 from the first state K1 (for example, Figure 7 and Figure 8 (as shown) moves (pivots) to the second state K2 (as shown) Fig. 9 and Fig.10 As shown in FIG. 1 , when the handle 26 moves from the first state K1 to the second state K2, the handle 26, the gear member 60, the actuator 62 and the drive member 70 have a linkage relationship (as the technical principle of this part has been disclosed in the above Figures 3 to 6 and its description, for the sake of simplicity, are not repeated here), so that the driving member 70 drives the lock member 80 and overcomes the elastic force of the extension section 112 of the auxiliary elastic member 110, so that the lock member 80 is from the locked state L1 (such as Figure 7 and Figure 8 As shown) moves to the unlocked state L2 (as shown Fig. 9 and Fig.1036), for example, the lock member 80 (the lock portion 90) is laterally (laterally) offset from the stop portion 34 (stop portion 36) to allow the second rail 24 to move relative to the first rail 22 from the folded position R to the opening direction D1, for example, to the predetermined extended position P1 (as shown in FIG. Fig. 9 and Fig.10 shown).

[0042] Furthermore, when the second rail 24 is at the predetermined extended position P1 relative to the first rail 22 (eg Fig. 9 and Fig.10 ), the auxiliary member 56 no longer abuts against the first rail 22 (the first end 22a), that is, the force F has stopped being applied to the auxiliary member 56, so that the auxiliary member 56 responds to the elastic feature 58 releasing the predetermined elastic force J and moves from the first auxiliary position C1 to the second auxiliary position C2, so that the latching feature 106 of the auxiliary member 56 can latch with the handle 26 (the predetermined portion 108) to keep the handle 26 in the second state K2 (as shown in FIG. Fig. 9 and Fig.10 As shown), the positions or states of the tooth row member 60, the actuating member 62, the driving member 70, the locking member 80, the operating member 94 and the second working member 92 are all maintained. For example, the driving member 70 is maintained in the second driving position N2, the locking member 80 is maintained in the unlocking state L2, the operating member 94 is maintained in the second operating position B2, and the second working member 92 is maintained in the second working state S2 (as shown). Fig. 9 and Fig.10 As shown), at this time, the elastic member 76 accumulates the elastic force Q (this part can be used in conjunction with Figure 5 ).

[0043] like Fig.11 As shown, the third rail 28 is in a predetermined open position E relative to the first rail 22, so that the first end 28a of the third rail 28 exceeds the first end 22a of the first rail 22 by a predetermined distance, and the third rail 28 can be maintained at the predetermined open position E relative to the first rail 22 through a positioning mechanism (since this part is a technical scope that can be understood by ordinary knowledgeable people familiar with the field, it will not be further elaborated here for the sake of simplicity).

[0044] Further, when the second rail 24 moves in the opening direction D1 relative to the third rail 28 (or the first rail 22) to a fully extended position P2 with a longer stroke, the first working member 90 in the first working state S1 can block the first blocking wall 46 of the blocking feature 44 to prevent the second rail 24 from continuing to move in the opening direction D1 from the fully extended position P2. However, since the second working member 92 is maintained in the second working state S2 and cannot block the second blocking wall 48 of the blocking feature 44, the second rail 24 can still move in a folding direction D2 from the fully extended position P2. When the second rail 24 is in the fully extended position P2 relative to the third rail 28 (or the first rail 22), the first end 24a of the second rail 24 exceeds the first end 28a of the third rail 28 by a predetermined distance.

[0045] like Fig.11 and Fig.12 As shown, when the second rail 24 is in the fully extended position P2 relative to the third rail 28, if the second rail 24 is to be positioned relative to the third rail 28 at the fully extended position P2, the auxiliary member 56 can be moved from the second auxiliary position C2 (such as when the user presses the auxiliary member 56) by applying the force F. Fig.11 As shown) back to the first auxiliary position C1 (as shown Fig.12 As shown), the auxiliary member 56 cannot engage with the handle 26. For example, the position of the engaging feature 106 of the auxiliary member 56 corresponds to the predetermined space M of the handle 26 (this part can be used in conjunction with Figure 4 and its description), so that the handle 26 can change from the second state K2 (such as Fig.11 As shown) returns to the first state K1 (as shown Fig.12 As shown), the driving member 70 responds to the elastic member 76 releasing the elastic force Q to drive the operating member 94 from the second operating position B2 (as shown). Fig.11 As shown) back to the first operating position B1 (as shown Fig.12 ), to allow the second working member 92 to change from the second working state S2 (as shown in Fig.11 As shown) moves to the first working state S1 (as shown Fig.12 Preferably, the second working member 92 can move from the second working state S2 to the first working state S1 in response to the second elastic section 99b releasing the elastic force. The second working member 92 in the first working state S1 and the second blocking wall 48 of the blocking feature 44 block each other to prevent the second rail 24 from moving from the fully extended position P2 to the folded direction D2 (as shown in FIG. Fig.12In short, the first working member 90 and the second working member 92 in the first working state S1 respectively block the first blocking wall 46 and the second blocking wall 48 of the blocking feature 44, thereby preventing the second rail 24 from leaving the fully extended position P2 (as shown in FIG. Fig.12 shown).

[0046] It is worth mentioning that if the second rail 24 is to be moved away from the fully extended position P2, the user can, for example, operate the second working member 92 through the operating member 94 to move the second working member 92 from the first working state S1 (eg, Fig.12 As shown) moves to the second working state S2 (as shown Fig.11 As shown), the second rail 24 is allowed to move from the fully extended position P2 to the folded direction D2; or, the first working member 90 is operated through another operating member 95 to move the first working member 90 from the first working state S1 to the second working state S2, so as to allow the second rail 24 to move from the fully extended position P2 to the open direction D1, so that the second rail 24 can be removed from the third rail 28.

[0047] In addition, when the second rail 24 is extended from an extended position (eg, the predetermined extended position P1, as shown in FIG. Fig. 9 and Fig.10 or, for example, the fully extended position P2, but the auxiliary member 56 is not applied to the force F) to the folding direction D2 back to the folded position R, the auxiliary member 56 again against the first rail 22 from the second auxiliary position C2 (such as Fig. 9 and Fig.10 ) returns to the first auxiliary position C1 (such as Figure 7 and Figure 8 ), so that the elastic feature 58 accumulates the predetermined elastic force J again, and the auxiliary member 56 is no longer engaged with the handle 26, so as to allow the handle 26 to return from the second state K2 to the first state K1. Preferably, the handle 26 can return from the second state K2 to the first state K1 in response to the elastic member 76 releasing the elastic force Q, and the locking member 80 locks the blocking portion 34 again to prevent the second rail 24 from leaving the folded position R (such as Figure 7 and Figure 8 ).

[0048] Preferably, the second rail 24 has an outer side and an inner side opposite to each other; the outer side of the second rail 24 is adjacent to or faces the first rail 22; the handle 26 includes a first end 27a, a second end 27b and an operating section 27c connected between the first end 27a and the second end 27b (such as Figure 8 or Fig.10When the handle 26 is in the second state K2, the operating section 27c of the handle 26 exceeds the inner side of the second rail 24 by a predetermined distance W (as shown in FIG. 24 ). Fig. 9 and Fig.10 As shown in FIG. 1 , the user can conveniently hold the second rail 24 and pull it out in the opening direction D1 relative to the first rail 22 .

[0049] Preferably, when the handle 26 is in the first state K1 (eg Figure 7 ), the configuration direction of the handle 26 is substantially the same as a height direction (eg, Z-axis direction) of the second rail 24; when the handle 26 is in the second state K2 (eg, Fig. 9 As shown in FIG. 2 , the configuration direction of the handle 26 is substantially the same as a side direction (eg, the Y-axis direction) of the second rail 24 .

[0050] Preferably, the displacement direction of the second rail 24 relative to the first rail 22 , the height direction and the lateral direction of the second rail 24 are perpendicular to each other.

[0051] It can be seen that the slide rail assembly 20 provided in the embodiment of the present invention includes the following features:

[0052] 1. The operating member 94 and the handle 26 are linked to each other, which helps to increase the convenience and functionality of the slide rail of the slide rail assembly 20 in use.

[0053] 2. When the second rail 24 is in the fully extended position P2 relative to the third rail 28, the user can apply the force F to press the auxiliary member 56, so that the auxiliary member 56 moves from the second auxiliary position C2 to the first auxiliary position C1, so that the auxiliary member 56 cannot be locked with the handle 26, and the handle 26 can return from the second state K2 to the first state K1 in response to the elastic force Q of the elastic member 76, and the driving member 70 can drive the operating member 94 to move from the second operating position B2 to the first operating position B1 in response to the elastic force Q of the elastic member 76, so as to allow the second working member 92 to move from the second working state S2 to the first working state S1, and the second working member 92 in the first working state S1 blocks each other with the second blocking wall 48 of the blocking feature 44, so as to prevent the second rail 24 from moving from the fully extended position P2 to the folding direction D2.

[0054] 3. When the second rail 24 is in the folded position R relative to the first rail 22, the auxiliary member 56 abuts against the first rail 22 and is in the first auxiliary position C1, so that the elastic feature 58 accumulates a predetermined elastic force J; when the handle 26 is operated and moves from the first state K1 to the second state K2, it is used to allow the second rail 24 to move from the folded position R to the opening direction D1 to the predetermined extended position P1; when the second rail 24 is in an extended position (for example, the predetermined extended position P1) relative to the first rail 22, the elastic feature 58 releases the predetermined elastic force J to the auxiliary member 56, so that the auxiliary member 56 moves from the first auxiliary position C1 to the second auxiliary position C2 and can engage with the handle 26 to keep the handle 26 in the second state K2.

[0055] 4. When the second rail 24 returns to the folded position R from an extended position (for example, the predetermined extended position P1 or the fully extended position P2) in the folded direction D2, the auxiliary member 56 again abuts against the first rail 22 and returns from the second auxiliary position C2 to the first auxiliary position C1, so that the elastic feature 58 accumulates the predetermined elastic force J, and the auxiliary member 56 is no longer engaged with the handle 26, so as to allow the handle 26 to return from the second state K2 to the first state K1. Preferably, the handle 26 can return from the second state K2 to the first state K1 in response to the elastic force Q of the elastic member 76.

[0056] 5. When the second rail 24 is at the folded position R relative to the first rail 22 , the lock 80 is used to lock the blocking portion 34 to prevent the second rail 24 from moving from the folded position R to the opening direction D1 .
