Description

Technical Field

[0001] The present invention relates to a slide rail mechanism, and in particular to a slide rail assembly which can release the locking relationship between two slide rails when they are in a predetermined position relative to each other by operating one of two operating parts. Background Art

[0002] US invention patent publication number US 6,883,884B2 discloses a latch assembly for a slide rail device, the slide rail device comprising a first rail and a second rail that can be relatively displaced. The first rail is provided with a latch assembly, and the second rail is provided with a latch seat. When the first rail is in a retracted position relative to the second rail, the latch assembly is engaged with the latch seat, so that the first rail is maintained in the retracted position. When unlocking, the user must simultaneously press the two actuating members of the latch assembly so that the hooks of the two corresponding unlocking members are no longer engaged with the latch seat, so as to allow the first rail to leave the retracted position relative to the second rail.

[0003] However, in order to meet the diverse needs of the market, how to develop a slide rail product that does not require simultaneous operation of two actuating members (or operating members) to release the locking or blocking relationship between the two slide rails has become an issue that cannot be ignored. Summary of the invention

[0004] The object of the present invention is to provide a slide rail assembly which can release the locking relationship between two slide rails when they are in a predetermined position relative to each other by operating one of two operating members.

[0005] According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a blocking feature, two operating members, and a locking member. The second rail and the first rail are displaceable relative to each other; the blocking feature is arranged on one of the first rail and the second rail; the two operating members are movably located on the other of the first rail and the second rail; the locking member is movably located on the other of the first rail and the second rail; wherein, when the second rail is in a predetermined position relative to the first rail, the locking member is in a locked state and can block the blocking feature to prevent the second rail from leaving the predetermined position; wherein, when one of the two operating members is operated, the locking member can be driven to move from the locked state to an unlocked state to allow the second rail to leave the predetermined position.

[0006] According to another aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a blocking feature, two operating members, and a locking member. The second rail is displaceable relative to the first rail; the blocking feature is arranged on the first rail; the two operating members are movably located on the second rail; the locking member is movably located on the second rail; wherein, when the second rail is in a predetermined position relative to the first rail, the locking member is in a locked state and can block the blocking feature to prevent the second rail from leaving the predetermined position; wherein, the slide rail assembly also includes a handle that is movable relative to the second rail; when the second rail is in the predetermined position relative to the first rail, the handle is used to operate one of the two operating members during the process of moving from a first operating position to a second operating position, and can drive the locking member to move from the locked state to an unlocked state to allow the second rail to leave the predetermined position.

[0019] like Figures 1 to 3 As shown, a slide rail assembly 20 of an embodiment of the present invention includes a first rail 22 and a second rail 24 that can be longitudinally displaced relative to each other. Preferably, the slide rail assembly 20 further includes a third rail 26 that is movably installed between the first rail 22 and the second rail 24. The third rail 26 includes a channel 27 that can be used to provide movably installed second rail 24. Here, the X axis is the longitudinal direction (or the length direction of the slide rail), the Y axis is the transverse direction (or the lateral direction of the slide rail), and the Z axis is the vertical direction (or the height direction of the slide rail) as an example.

[0020] Furthermore, the slide rail assembly 20 further includes a blocking feature 28, a locking member 30 and two operating members. The locking member 30 is used in conjunction with the blocking feature 28. The two operating members are, for example, a first operating member 31 and a second operating member 32.

[0021] The blocking feature 28 is arranged on one of the first rail 22 and the second rail 24. Here, the blocking feature 28 is arranged on the first rail 22 as an example (eg, Figure 2 ), but the implementation is not limited. The blocking feature 28 can be directly or indirectly configured on the first rail 22. Here, the blocking feature 28 is taken as a groove wall or a hole wall; or, in an alternative embodiment, the blocking feature 28 can be a protrusion. Therefore, the implementation form of the blocking feature 28 is not limited. Preferably, 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, and the blocking feature 28 is arranged adjacent to the first end 22a of the first rail 22.

[0022] The lock member 30, the first operating member 31 and the second operating member 32 are movably located on the other of the first rail 22 and the second rail 24. Here, the lock member 30, the first operating member 31 and the second operating member 32 are movably located on the second rail 24 as an example. Preferably, 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, and the lock member 30, the first operating member 31 and the second operating member 32 are movably installed on the first end 24a adjacent to the second rail 24.

[0023] Preferably, the slide rail assembly 20 further includes a driving member 33 movably located at the other of the first rail 22 and the second rail 24. Further, the driving member 33 is movably located at the second rail 24, for example, movably installed at the first end 24a adjacent to the second rail 24 (for example, Figure 3 shown).

[0024] Preferably, the second rail 24 is provided with a housing 34 (eg Figure 2 As shown in FIG. 1 , the housing 34 is connected (for example, fixed) to and adjacent to the first end 24a of the second rail 24 and can be regarded as a part of the second rail 24. The housing 34 includes a first housing portion 34a and a second housing portion 34b (as shown in FIG. 1 ) connected to each other. Figure 2 As shown, Figure 3 Only the first shell 34a is shown to represent the housing 34). Preferably, the first shell 34a and the second shell 34b are detachably mounted to each other, and a receiving space is defined between the first shell 34a and the second shell 34b. The lock member 30, the first operating member 31, the second operating member 32 and the driving member 33 are movably arranged on the first shell 34a of the first end 24a of the second rail 24 (such as Figure 3 ). Further, the first shell 34a and the second shell 34b can accommodate and / or cover a portion of the lock 30, the first operating member 31, the second operating member 32 and the driving member 33, thereby providing protection; or, in other alternative embodiments, the lock 30, the first operating member 31, the second operating member 32 and the driving member 33 can be directly arranged on the second rail 24 and adjacent to the first end 24a of the second rail 24 without passing through the shell 34, and therefore, the implementation is not limited thereto.

[0025] like Figure 3 and Figure 4 As shown ( Figure 4Only the first shell portion 34a is shown to represent the housing 34), the driving member 33 includes a first contact portion 36, a second contact portion 38 and an intermediate portion 40 located between the first contact portion 36 and the second contact portion 38, and the intermediate portion 40 is pivotally connected to the second rail 24 through a first axis 42, for example, pivotally connected to the first shell portion 34a on the second rail 24.

[0026] Preferably, the lock 30 is pivotally connected to the second rail 24 via a second shaft 44, such as the first housing 34a on the second rail 24. The second shaft 44 and the first shaft 42 have substantially the same direction in the horizontal direction (or lateral direction, i.e., Y-axis direction) of the second rail 24.

[0027] Preferably, the first operating member 31 has a first corresponding feature 46 facing the first contact portion 36 of the driving member 33, and the second operating member 32 has a second corresponding feature 48 facing the second contact portion 38 of the driving member 33. According to this configuration, when one of the first operating member 31 and the second operating member 32 is operated (for example, when the first operating member 31 or the second operating member 32 is operated), the driving member 33 can be linked.

[0028] Preferably, the slide rail assembly 20 further includes an elastic member 50. The lock member 30 can be maintained in a locked state K1 in response to the elastic force of the elastic member 50. The lock member 30 in the locked state K1 is used to support one of the first contact portion 36 and the second contact portion 38, so that the driving member 33 supports the first operating member 31 and the second operating member 32 in a first state S1. Specifically, the lock member 30 includes a lock portion 52, an auxiliary portion 54, and an intermediate section 56 located between the lock portion 52 and the auxiliary portion 54. The intermediate section 56 is pivotally connected to the first shell portion 34a on the second rail 24 through the second shaft 44. The lock member 30 in the locked state K1 is used to support (for example, abut) the first contact portion 36 (for example, the auxiliary portion 54) through the auxiliary portion 54. Figure 4 ), the driving member 33 can support the first operating member 31 and the second operating member 32 in the first state S1 (this part can also be referred to in conjunction with FIG. 5 ), so that the driving member 33 can contact the first corresponding feature 46 of the first operating member 31 and the second corresponding feature 48 of the second operating member 32 through the first contact portion 36 and the second contact portion 38 respectively. Figure 5 ).

[0029] Preferably, the elastic member 50 includes a first elastic portion 51a, a second elastic portion 51b and a mounting portion 53 connected between the first elastic portion 51a and the second elastic portion 51b; the first elastic portion 51a contacts the first shell portion 34a on the second rail 24, the second elastic portion 51b contacts the lock member 30, and the mounting portion 53 is mounted to the second shaft 44.

[0030] Preferably, the second rail 24 includes at least one blocking portion, and here, a first blocking portion 58 and a second blocking portion 60 are taken as an example, and the first blocking portion 58 and the second blocking portion 60 are used to respectively keep the first operating member 31 and the second operating member 32 in the first state S1 (such as Figure 3 shown).

[0031] Preferably, the first operating member 31 and the second operating member 32 include a first guide structure 62 and a second guide structure 64 that match each other. The directions of the first guide structure 62 and the second guide structure 64 are substantially the same as the height direction (i.e., the Z-axis direction) of the second rail 24. Here, the first guide structure 62 and the second guide structure 64 are taken as an example to be a rib and a groove respectively, but the implementation is not limited thereto.

[0032] Preferably, the first operating member 31 and the second operating member 32 further include a third guide structure 66 and a fourth guide structure 68 that match each other. The directions of the third guide structure 66 and the fourth guide structure 68 are substantially the same as the height direction (i.e., the Z-axis direction) of the second rail 24. Here, the third guide structure 66 and the fourth guide structure 68 are respectively a groove and a rib for example, but the implementation is not limited thereto.

[0033] Preferably, the first corresponding feature 46 of the first operating member 31 is located adjacent to the end of the first guiding structure 62, and the second corresponding feature 48 of the second operating member 32 is located adjacent to the end of the fourth guiding structure 68 (this part can also be referred to in conjunction with Figure 5 ).

[0034] Preferably, the first operating member 31 and the second operating member 32 respectively include a first operating portion 70 and a second operating portion 72 that can be operated by a user by pressing. The first operating portion 70 and the second operating portion 72 are located at opposite positions. Specifically, the first operating portion 70 is located at a first height position (e.g., a lower position) close to the second rail 24, and the second operating portion 72 is located at a second height position (e.g., an upper position) close to the second rail 24.

[0035] Preferably, the first guide structure 62 and the third guide structure 66 extend from the first operating portion 70 of the first operating member 31, and the first guide structure 62 and the third guide structure 66 are spaced apart from each other; similarly, the second guide structure 64 and the fourth guide structure 68 extend from the second operating portion 72 of the second operating member 32, and the second guide structure 64 and the fourth guide structure 68 are spaced apart from each other.

[0036] Preferably, the driving member 33 is located between the first operating member 31 and the second operating member 32 .

[0037] like Figure 5 As shown, when the second rail 24 is at a predetermined position P (e.g., a folded position) relative to the first rail 22, the lock 30 is in the locked state K1, so that the lock portion 52 of the lock 30 can block the blocking feature 28 of the first rail 22 to prevent the second rail 24 from leaving the predetermined position P. The lock 30 is in the locked state K1, so that the lock portion 52 and the blocking feature 28 correspond to each other in the longitudinal direction, so that the lock portion 52 and the blocking feature 28 can block each other.

[0038] like Figure 5 and Figure 6 As shown, when one of the first operating member 31 and the second operating member 32, for example, the first operating member 31 is operated, the lock member 30 can be driven from the locked state K1 (eg Figure 5 As shown) moves to an unlocked state K2 (as shown Figure 6 ), for allowing the second rail 24 to leave the predetermined position P, for example, for allowing the second rail 24 to move from the predetermined position P to a predetermined direction D1.

[0039] Preferably, when the first operating member 31 is operated, the driving member 33 can be linked (for example, the driving member 33 can be pivoted to a predetermined angle), thereby enabling the driving member 33 to drive the lock member 30 from the locked state K1 (for example, Figure 5 As shown) moves to the unlocked state K2 (as shown Figure 6 As shown), to allow the second rail 24 to leave the predetermined position P.

[0040] Preferably, the first corresponding feature 46 of the first operating member 31 is oriented toward the first contact portion 36 of the driving member 33 in a first predetermined direction (for example, upward); on the other hand, the second corresponding feature 48 of the second operating member 32 is oriented toward the second contact portion 38 of the driving member 33 in a second predetermined direction (for example, downward) opposite to the first predetermined direction.

[0041] Further, the user applies a first force F1 to one of the first operating member 31 (the first operating portion 70) and the second operating member 32 (the second operating portion 72). For example, when the first force F1 is applied to the first operating member 31 (the first operating portion 70), the first operating member 31 can be pressed from the first state S1 (such as Figure 5 As shown) moves to a second state S2 (as shown Figure 6 In this process, the first corresponding feature 46 of the first operating member 31 contacts (e.g., pushes against) the first contact portion 36 of the driving member 33, so that the driving member 33 is movable, and the driving member 33 can be used to drive the lock member 30 from the locked state K1 (e.g., Figure 5As shown) moves to the unlocked state K2 (as shown Figure 6 ), so as to allow the second rail 24 to move from the predetermined position P to the predetermined direction D1. The locking member 30 is in the unlocked state K2, so that the locking portion 52 and the blocking feature 28 no longer correspond to each other in the longitudinal direction, for example, the locking portion 52 and the blocking feature 28 are staggered (as shown in FIG. Figure 6 ), so that the locking portion 52 cannot block the blocking feature 28, so as to allow the second rail 24 to move from the predetermined position P to the predetermined direction D1. In addition, when the lock member 30 is in the unlocked state K2 (as shown in FIG. Figure 6 As shown in FIG. 5 , the elastic member 50 is in a state of accumulating an elastic force.

[0042] When the first operating member 31 is applied with the first force F1 from the first state S1 (such as Figure 5 As shown) moves to the second state S2 (as shown Figure 6 In the process of the first operating member 31 being moved from the first state S1 (as shown in FIG. 1 ), the first guiding structure 62 of the first operating member 31 and the second guiding structure 64 of the second operating member 32 can avoid each other; and the third guiding structure 66 of the first operating member 31 and the fourth guiding structure 68 of the second operating member 32 can avoid each other. In short, the first operating member 31 is moved from the first state S1 (as shown in FIG. 1 ) to the second state S2 (as shown in FIG. 1 ). Figure 5 As shown) moves to the second state S2 (as shown Figure 6 As shown in FIG. 1 , the second operating member 32 will not be linked.

[0043] It is worth mentioning that when the lock element 30 is in the unlocked state K2 (eg Figure 6 ), the second rail 24 can move relative to the first rail 22 from the predetermined position P to the predetermined direction D1 to another predetermined position (e.g., an open position, not shown), wherein, once the user stops applying the first force F1 to the first operating member 31 (the first operating portion 70), the lock member 30 responds to the elastic member 50 releasing the elastic force from the unlocked state K2 (e.g., Figure 6 As shown) returns to the locked state K1 (as shown Figure 5 As shown), and the lock member 30 in the locked state K1 is used to support the first contact portion 36, so that the driving member 33 can contact the first corresponding feature 46 through the first contact portion 36 and the first operating member 31 can be kept in the first state S1 again (as shown Figure 5 shown).

[0044] like Figure 5 and Figure 7 As shown, when the second operating member 32 is operated, the lock member 30 can also be driven from the locked state K1 (as shown in FIG. Figure 5 As shown) moves to the unlocked state K2 (as shown Figure 7As shown), to allow the second rail 24 to leave the predetermined position P, for example, to allow the second rail 24 to move from the predetermined position P to the predetermined direction D1.

[0045] Preferably, when the second operating member 32 is operated, the driving member 33 can be linked (for example, the driving member 33 can be pivoted to a predetermined angle), thereby enabling the driving member 33 to drive the lock member 30 from the locked state K1 (for example, Figure 5 As shown) moves to the unlocked state K2 (as shown Figure 7 As shown), to allow the second rail 24 to leave the predetermined position P.

[0046] Furthermore, the user may apply a second force F2 in a direction opposite to the first force F1 to the second operating member 32 (the second operating portion 72) to press the second operating member 32 from the first state S1 (eg Figure 5 As shown) moves to the second state S2 (as shown Figure 7 In this process, the second corresponding feature 48 of the second operating member 32 contacts (e.g., pushes against) the second contact portion 38 of the driving member 33, so that the driving member 33 is movable, and the driving member 33 can be used to drive the lock member 30 from the locked state K1 (e.g., Figure 5 As shown) moves to the unlocked state K2 (as shown Figure 7 ), so as to allow the second rail 24 to move from the predetermined position P to the predetermined direction D1. The locking member 30 is in the unlocked state K2, so that the locking portion 52 and the blocking feature 28 no longer correspond to each other in the longitudinal direction, for example, the locking portion 52 and the blocking feature 28 are staggered (as shown in FIG. Figure 7 ), so that the locking portion 52 cannot block the blocking feature 28, so as to allow the second rail 24 to move from the predetermined position P to the predetermined direction D1. In addition, when the lock member 30 is in the unlocked state K2 (as shown in FIG. Figure 7 As shown in FIG. 5 , the elastic member 50 is in a state of accumulating an elastic force.

[0047] When the second operating member 32 is applied with the second force F2 from the first state S1 (such as Figure 5 As shown) moves to the second state S2 (as shown Figure 7 In the process of the first state S1 (as shown in FIG. 1 ), the first guide structure 62 of the first operating member 31 and the second guide structure 64 of the second operating member 32 can avoid each other; and the third guide structure 66 of the first operating member 31 and the fourth guide structure 68 of the second operating member 32 can avoid each other. In short, the second operating member 32 is changed from the first state S1 (as shown in FIG. 1 ) to the second state S2 (as shown in FIG. 1 ). Figure 5 As shown) moves to the second state S2 (as shown Figure 7 As shown), the first operating member 31 will not be linked.

[0048] It is worth mentioning that when the lock element 30 is in the unlocked state K2 (eg Figure 7 ), the second rail 24 can move relative to the first rail 22 from the predetermined position P to the predetermined direction D1 to another predetermined position (e.g., the open position, not shown), wherein, once the user stops applying the second force F2 to the second operating member 32 (the second operating portion 72), the lock member 30 responds to the elastic member 50 releasing the elastic force from the unlocked state K2 (e.g., Figure 7 As shown) returns to the locked state K1 (as shown Figure 5 As shown), and the lock member 30 in the locked state K1 is used to support the first contact portion 36, so that the driving member 33 can contact the second corresponding feature 48 through the second contact portion 38 and the second operating member 32 can be kept in the first state S1 again (as shown Figure 5 shown).

[0049] It can be seen that the user can release the locking (blocking) relationship between the second rail 24 and the first rail 22 when they are in the predetermined position P relative to each other by operating the first operating member 31 or the second operating member 32, so as to allow the second rail 24 to leave the predetermined position P.

[0050] like Figure 8 As shown, a plurality of slide rail assemblies 20 can be installed on a rack 74 (or cabinet) along a height direction (e.g., Z-axis direction), and these slide rail assemblies 20 have substantially the same structural configuration. Further, taking the example of the second rail 24 of the slide rail assembly 20 installed at the highest position of the rack 74 being locked at the predetermined position P relative to the first rail 22, the slide rail assembly 20 at the highest position may not be easy for the user's hand H to touch and operate the second operating member 32 (the second operating portion 72), so the user can choose to operate the first operating member 31 (the first operating portion 70) to drive the lock member 30 from the locked state K1 (this part can be referred to in conjunction with Figure 5 As shown) to the unlocked state K2 (this part can be referred to in conjunction with Figure 6 As shown in FIG. 1 , the second rail 24 of the slide rail assembly 20 at the highest position is allowed to move from the predetermined position P to the predetermined direction D1. As the technical principle of this part has been disclosed above, it will not be repeated here for the sake of simplicity.

[0051] like Fig. 9As shown in FIG. 1 , taking the second rail 24 of the slide rail assembly 20 installed at the lowest position of the frame 74 being locked at the predetermined position P relative to the first rail 22 as an example, the slide rail assembly 20 at the lowest position may not be easy for the user's hand H to touch and operate the first operating member 31 (the first operating portion 70), so the user may choose to operate the second operating member 32 (the second operating portion 72) to drive the lock member 30 from the locked state K1 (this part can be referred to in conjunction with Figure 5 As shown) to the unlocked state K2 (this part can be referred to in conjunction with Figure 7 As shown in FIG. 1 , the second rail 24 of the slide rail assembly 20 at the lowest position is allowed to move from the predetermined position P to the predetermined direction D1. As the technical principle of this part has been disclosed above, it will not be repeated here for the sake of simplicity.

[0052] like Fig.10 As shown, the first rail 22 is provided with a bracket 76 (or a support), and the bracket 76 and the first rail 22 are interconnected and can be regarded as a whole. Preferably, the first rail 22 can be mounted to the frame 74 through the bracket 76; the second rail 24 is locked at the predetermined position P relative to the first rail 22, and the second rail 24 can be used to carry a carrier 77 (such as a chassis or a drawer or the like). Further, the carrier 77 is installed (such as fixed) to the second rail 24 and can be regarded as a part of the second rail 24. 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.

[0053] The slide rail assembly 20 further includes a handle 78. The handle 78 can move relative to the second rail 24. Here, the handle 78 is pivotally connected to the carrier 77 (at the bottom) through an auxiliary shaft 80, so that the handle 78 can pivot relative to the second rail 24; or, the second rail 24 includes a predetermined structure, and the handle 78 can be directly pivotally connected to the predetermined structure of the second rail 24, so that the handle 78 can also pivot relative to the second rail 24. Therefore, the implementation is not limited.

[0054] like Figure 10 to Figure 11 As shown, when the second rail 24 is at the predetermined position P relative to the first rail 22, the handle 78 can be operated by the user from a first operating position M1 (eg, Fig.10 ) moves (e.g. pivots) to a second operating position M2 (e.g. Fig.11 In this process, the handle 78 can operate one of the first operating member 31 and the second operating member 32. For example, the handle 78 can apply the first force F1 to the first operating member 31 (as shown in FIG. Fig.11 As shown), the lock member 30 can be driven from the locked state K1 (this part can be used in conjunction with Figure 5) to the unlocked state K2 (this part can be referred to in conjunction with Figure 6 ) to allow the second rail 24 to leave the predetermined position P.

[0055] Preferably, one of the handle 78 and the first operating member 31 (the first operating portion 70) includes a guide feature 82, and the guide feature 82 is, for example, an inclined surface or an arc surface. Here, the handle 78 is taken as an example including the guide feature 82, but the implementation is not limited thereto. The handle 78 can more easily apply the first force F1 to the first operating member 31 through the guide feature 82, thereby driving the lock member 30 from the locked state K1 (this part can cooperate with Figure 5 ) to the unlocked state K2 (this part can be coordinated with Figure 6 ) to allow the second rail 24 to leave the predetermined position P.

[0056] Preferably, the handle 78 further includes a predetermined portion 83, and the predetermined portion 83 is configured with the guide feature 82; the first rail 22 includes a fulcrum feature 84; when the handle 78 moves from the first operating position M1 to the second operating position M2, the predetermined portion 83 of the handle 78 and one end 84a of the fulcrum feature 84 contact each other to generate a force (such as Fig.11 As shown), the second rail 24 is used to move toward the predetermined direction D1 by a predetermined distance and leave the predetermined position P.

[0057] Therefore, in addition to releasing the lock of the second rail 24 at the predetermined position P relative to the first rail 22 through the handle 78, the contact between the handle 78 and the fulcrum feature 84 can generate a force, which can conveniently or labor-savingly pull the second rail 24 (carrier 77) relative to the first rail 22 (frame 74) from the predetermined position P to the predetermined direction D1 for the user.

[0058] It can be seen that the slide rail assembly 20 provided in the embodiment of the present invention includes the following features:

[0059] 1. Different from the prior art in which the user must press the two actuating members of the latch assembly at the same time, in the present embodiment, when the second rail 24 is in the predetermined position P relative to the first rail 22, the lock member 30 is in the locked state K1 and can block the blocking feature 28. The user only needs to operate (for example, press or push) one of the first operating member 31 and the second operating member 32 to drive the lock member 30 from the locked state K1 to the unlocked state K2, so that the lock member 30 (the locking portion 52) no longer blocks the blocking feature 28, so as to allow the second rail 24 to leave the predetermined position P relative to the first rail 22.

[0060] 2. The first operating portion 70 of the first operating member 31 can provide the user with a first force F1 in a first direction to press, and the second operating portion 72 of the second operating member 32 can provide the user with a second force F2 in a second direction opposite to the first direction, wherein the first operating member 31 or the second operating member 32 can be used to drive the lock member 30 to move from the locked state K1 to the unlocked state K2.

[0061] 3. The first operating portion 70 of the first operating member 31 is located at a first height position (eg, a lower position) close to the second rail 24 , and the second operating portion 72 of the second operating member 32 is located at a second height position (eg, an upper position) close to the second rail 24 .

[0062] 4. The handle 78 is movable relative to the second rail 24 ; the user can operate one of the first operating member 31 and the second operating member 32 through the handle 78 to release the lock of the second rail 24 at the predetermined position P relative to the first rail 22 .

[0063] 5. During the operation of the handle 78, the handle 78 can contact the fulcrum feature 84 to generate a force, which can conveniently or labor-savingly pull the second rail 24 (carrier 77) relative to the first rail 22 (frame 74) from the predetermined position P to the predetermined direction D1.

[0064] 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.
