Description

Technical Field

[0001] This invention relates to a slide rail, and more particularly to a slide rail assembly in which a blocking mechanism is activated by an operating element to allow the user to select whether to activate when two slide rails are displaced relative to each other to a working position. Background Technology

[0002] Generally, slide rail assemblies are applied to racks or cabinets to support a load (such as electronic equipment or drawers). The slide rail assembly typically includes an outer rail and an inner rail that are movable relative to each other. Preferably, it also includes a middle rail movably mounted between the outer and inner rails, extending the travel of the inner rail relative to the outer rail. Typically, the inner rail can displace relative to the outer rail between a retracted position and an extended position.

[0003] With the development of the slide rail industry, the ability of any two slide rails (such as inner rail and middle rail or middle rail and outer rail) to block or position each other when they are moved to a predetermined position has gradually become more common.

[0004] For example, US Patent Publication No. 6,935,710B2 discloses a slide rail assembly including a first rail (inner rail), a second rail (middle rail) and a third rail (outer rail), wherein when the first rail moves to an extended position relative to the second rail, the first rail and the second rail can be stopped relative to each other in the extended position by two retaining arms. However, this stopping mechanism is mandatory. More specifically, whenever the first rail moves to the extended position relative to the second rail, the first rail is preset to be stopped and positioned in the extended position by the two retaining arms.

[0005] For example, US Patent Publication No. 10,743,660B2 discloses a slide rail assembly comprising a first rail (middle rail), a second rail (inner rail), and a third rail (outer rail). When the second rail moves relative to the first rail to a first extended position, it is stopped relative to the first rail at that first extended position by two components (a first component and a second component); when the second rail moves relative to the first rail to a second extended position, it is stopped relative to the first rail at that second extended position by two additional components (a third component and a fourth component). However, the stopping mechanism is mandatory; more specifically, whenever the second rail moves relative to the first rail to the first extended position (or the second extended position), the second rail is pre-set to be stopped and positioned at that first extended position (or the second extended position) by the two components (or the two additional components).

[0006] Although the aforementioned patent has revealed that two slide rails displace relative to each other to the extended position, they will inevitably be stopped at the extended position, however, with different market demands, how to develop a different slide rail product has become an issue that cannot be ignored. Summary of the Invention

[0007] The purpose of this invention is to provide a slide rail assembly in which a user can select whether to activate a blocking mechanism when two slide rails are displaced relative to each other to a working position via an operating element.

[0008] According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, an elastic element, and an operating element. The first rail includes a predetermined feature; the second rail is longitudinally displaceable relative to the first rail; the elastic element is disposed on the second rail; the operating element is movable relative to the second rail between a first operating position and a second operating position; wherein, when the operating element is in the first operating position, the operating element abuts against the elastic element, and during the displacement of the second rail relative to the first rail in a first direction, the elastic element fails to block the predetermined feature, thereby allowing the second rail to directly pass over the predetermined feature; wherein, when the operating element is in the second operating position, the operating element no longer abuts against the elastic element, and during the displacement of the second rail relative to the first rail in the first direction, the elastic element can block the predetermined feature, thereby stopping the second rail in a working position.

[0009] According to another aspect of the present invention, a slide rail assembly includes a first rail, a second rail, an elastic element, and an operating element. The first track includes a predetermined feature, and the predetermined feature includes a first wall segment; the second track is longitudinally displaceable relative to the first track; an elastic member is arranged on the second track, and the elastic member includes an auxiliary portion; the operating member is movable relative to the second track between a first operating position and a second operating position; wherein, when the operating member is in the first operating position, the operating member supports the elastic member, causing the elastic member to accumulate a spring force in a predetermined state, thereby providing the second track to displace relative to the first track from a first predetermined position in a first direction and directly pass over the predetermined feature; wherein, when the operating member is in the second operating position, the operating member no longer supports the elastic member, causing the elastic member to leave the predetermined state in response to the spring force, thereby providing the second track to displace relative to the first track from the first predetermined position in the first direction to a working position, and the auxiliary portion and the first wall segment of the predetermined feature block each other, causing the second track to remain in the working position to prevent the second track from displacing from the working position in the first direction.

[0010] According to another aspect of the present invention, a slide rail assembly includes a first rail, a second rail, an elastic member, and an operating member. The first rail includes a predetermined feature, and the predetermined feature includes a first wall segment; the second rail is longitudinally displaceable relative to the first rail; the elastic member is disposed on the second rail and includes an auxiliary portion; the operating member is movable relative to the second rail between a first operating position and a second operating position, the operating member includes a protrusion, and the protrusion of the operating member and one of the elastic members have a guide segment; wherein, when the operating member is in the first operating position, the protrusion of the operating member supports the elastic member, causing the elastic member to accumulate a spring force in a predetermined state, providing that during the displacement of the second rail relative to the first rail from a first predetermined position to a second predetermined position, the elastic member is in the predetermined state, and the auxiliary portion and the first wall segment of the predetermined feature do not obstruct each other; wherein, when the operating member is in the second operating position... The protrusion of the operating member no longer supports the elastic member, allowing the elastic member to leave the predetermined state in response to the elastic force. This is to provide that during the process of the second rail relative to the first rail moving from the first predetermined position to the second predetermined position in the first direction, the auxiliary part and the first wall segment of the predetermined feature mutually block each other, causing the second rail to remain in a working position to prevent the second rail from moving from the working position to the second predetermined position in the first direction. When the second rail is in the working position relative to the first rail, and the operating member returns from the second operating position to the first operating position, the operating member can drive the elastic member through the guide section, so that the protrusion of the operating member can support the elastic member again, and the auxiliary part of the elastic member no longer blocks each other with the first wall segment of the predetermined feature, allowing the second rail to move from the working position to the second predetermined position in the first direction.

[0011] Overall, the operating device allows the user to choose whether to activate the blocking mechanism when the second rail is displaced relative to the first rail to a working position. Attached Figure Description

[0031] like Figure 1 and Figure 2 As shown, a slide rail assembly 20 according to a first embodiment of the present invention includes a first rail 22 and a second rail 24. Preferably, it also includes a third rail 26 movably mounted between the first rail 22 and the second rail 24, and the first rail 22, the second rail 24, and the third rail 26 are longitudinally displaceable relative to each other. 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). Preferably, the first rail 22 is, for example, an outer rail, the second rail 24 is, for example, an inner rail, and the third rail 26 is, for example, a middle rail, but the implementation is not limited.

[0032] The first track 22 includes a first wall 28a, a second wall 28b, and a longitudinal wall 30 connecting the first wall 28a and the second wall 28b of the first track 22. The first wall 28a, the second wall 28b, and the longitudinal wall 30 of the first track 22 together define a first channel 32 for accommodating the third track 26 and a portion of the second track 24. The first track 22 has a first end 22a and a second end 22b (e.g., a front end and a rear end) positioned opposite each other. Furthermore, the longitudinal wall 30 of the first track 22 includes a predetermined feature 34, preferably adjacent to the first end 22a of the first track 22. Here, the predetermined feature 34 serves as an opening, and the opening is defined by a plurality of wall segments, but the implementation is not limited.

[0033] The third track 26 includes a first wall 36a, a second wall 36b, and a longitudinal wall 38 connecting the first wall 36a and the second wall 36b of the third track 26. The first wall 36a, the second wall 36b, and the longitudinal wall 38 of the third track 26 together define a second channel 40 for accommodating the second track 24. The third track 26 has a first end 26a and a second end 26b (e.g., a front end and a rear end) positioned opposite each other. Preferably, the third track 26 includes an auxiliary feature 42, which is a protrusion adjacent to the first end 26a of the third track 26. The auxiliary feature 42 can be arranged directly or indirectly on the longitudinal wall 38 of the third track 26.

[0034] The second track 24 includes a first wall 44a, a second wall 44b, and a longitudinal wall 46 connecting the first wall 44a and the second wall 44b of the second track 24.

[0035] like Figure 3 and Figure 4 As shown, a mechanical control device is arranged on the second rail 24 to allow the user to control the second rail 24 when it is in a first predetermined position P1 relative to the first rail 22 (e.g., a retracted position). Figure 9 As shown), the control device of the first embodiment of the present invention can pre-select whether to activate or not, and the blocking relationship between the first rail 22 and the second rail 24 in an extended default position. The control device includes an elastic member 48 and an operating member 50. The elastic member 48 is connected to the second rail 24, and the operating member 50 is movable relative to the second rail 24. The second rail 24 has a first end 24a and a second end 24b (e.g., front end and rear end) opposite to each other, and a first side L1 and a second side L2 (e.g., inner side and outer side) opposite to each other, wherein the first side L1 faces the first rail 22 (or the third rail 26).

[0036] Preferably, the elastic element 48 is, for example, a spring sheet, but the implementation is not limited thereto. The second rail 24 includes a predetermined hole 52 connecting a first side L1 and a second side L2 of the second rail 24. The elastic element 48 includes a connecting portion 54 and an elastic arm 56 extending from the connecting portion 54. The connecting portion 54 is connected (e.g., fixed) to the first side L1 of the second rail 24. The position of the elastic arm 56 corresponds to the predetermined hole 52 of the second rail 24, and the elastic arm 56 is provided with an auxiliary portion 58, which is, for example, a protrusion or a projecting structure, but the implementation is not limited thereto.

[0037] Preferably, the second rail 24 is provided with an extension 60. More specifically, the extension 60 is connected (e.g., fixed) to the first side L1 of the second rail 24 and can be considered as part of the second rail 24. The extension 60 is adjacent to the first end 24a of the second rail 24. The extension 60 includes a first extension 62 and a second extension 64, and a mounting space 66 is defined between the first extension 62 and the second extension 64. Furthermore, the first extension 62 and the second extension 64 have a lateral spacing to form the mounting space 66. In addition, the first extension 62 has a corresponding hole 68. The mounting space 66 is used for the longitudinal insertion of the elastic arm 56 of the elastic member 48, and the auxiliary part 58 is laterally aligned with the corresponding hole 68. The first extension 62 and the second extension 64 can be used to limit the elastic range of motion of the elastic arm 56 of the elastic member 48. The operating element 50 is movably mounted on the extension 60 of the second rail 24.

[0038] Preferably, the operating member 50 is longitudinally movable relative to the second rail 24. Furthermore, one of the operating member 50 and one of the extensions 60 of the second rail 24 are provided with a plurality of longitudinal holes 70, and the other of the operating member 50 and the extension 60 of the second rail 24 pass through a portion of these longitudinal holes 70 through a plurality of protrusions 72, such that the operating member 50 can only move relative to the second rail 24 within a limited range. Each protrusion 72 is, for example, connected to the extension 60 of the second rail 24.

[0039] Preferably, the slide rail assembly 20 also includes a restoring elastic element 74 for providing elasticity to the operating element 50.

[0040] Preferably, the slide rail assembly 20 also includes an extension 60 on which a button 76 is movably mounted on the second rail 24, and an auxiliary elastic member 78 for providing elastic force to the button 76.

[0041] Preferably, the slide rail assembly 20 further includes a first housing 80 and a second housing 82, which can, for example, help improve the stability or reliability of the operating member 50 and / or the button 76 when mounted to the extension 60 of the second rail 24. The first housing 80 includes a first mounting feature 84 for connecting (e.g., by riveting or screwing, but not limited to) a second mounting feature 86 to the extension 60 of the second rail 24. The first housing 80 and the second housing 82 are detachably connected to each other via a first mounting portion 88 and a second mounting portion 90, which, for example, have a convex-concave structure, but are not limited to. Furthermore, the operating member 50 also includes a first predetermined portion 92 that can correspondingly insert into a predetermined space 93 of the second housing 82, and the first predetermined portion 92 of the operating member 50 can be used in conjunction with a second predetermined portion 94 of the button 76. On the other hand, the second housing 82 also includes an auxiliary hole 96 through which the button 76 can pass (this part can be referred to in conjunction with the previous section). Figure 1 Furthermore, the second pre-positioned part 94 abuts against an inner wall of the second housing 82 to limit the range of motion of the button 76.

[0042] like Figure 5 and Figure 6As shown, the first housing 80 and the second housing 82 are omitted from the drawing. The operating member 50 has a first end 50a and a second end 50b (e.g., a front end and a rear end). The operating member 50 also includes an operating portion 98 and a protrusion 100. The operating portion 98 is connected to and adjacent to the first end 50a of the operating member 50, and the protrusion 100 is connected to and adjacent to the second end 50b of the operating member 50. One of the protrusion 100 and the elastic member 48 has a guide section 102. Here, it is assumed that the protrusion 100 has the guide section 102, and the guide section 102 is, for example, a slope or an arc surface, but the implementation is not limited to this.

[0043] Furthermore, the operating member 50 can be in a first operating position K1 relative to the second rail 24. When the operating member 50 is in the first operating position K1, the protrusion 100 of the operating member 50 is used to support the elastic member 48 (for example, the protrusion 100 of the operating member 50 abuts against the elastic arm 56 of the elastic member 48), so that the elastic arm 56 of the elastic member 48 can be kept in a predetermined state S1 and accumulate an elastic force F1 towards the longitudinal wall 30 of the first rail 22 (e.g., Figure 6 As shown), at this time, the auxiliary part 58 is partially located in the corresponding hole 68 (e.g. Figure 5 (As shown).

[0044] Preferably, the first predetermined portion 92 of the operating member 50 extends from the operating portion 98; when the operating member 50 is in the first operating position K1, the operating member 50 presses the button 76, so that the button 76 is in an unobstructed state B1. For example, the first predetermined portion 92 of the operating member 50 can press the second predetermined portion 94 of the button 76, so that the button 76 is in the unobstructed state B1. At this time, the auxiliary elastic member 78 is in a state of accumulating an auxiliary elastic force F2 (e.g., Figure 6 (As shown). The direction of the auxiliary elastic force F2 is opposite to the direction of the elastic force F1.

[0045] like Figure 7 and Figure 8 As shown, the operating element 50 can be in a second operating position K2 relative to the second rail 24. For example, the user can apply a predetermined force M in a predetermined operating direction to the operating part 98 of the operating element 50 (this part can be referred to in conjunction with the description of the second operating position K2). Figure 6 This causes the operating member 50 to move longitudinally from the first operating position K1 to the second operating position K2. At this time, the restoring elastic member 74 accumulates a restoring elastic force F3 (e.g., ...). Figure 8(As shown). When the operating member 50 is in the second operating position K2, the protrusion 100 of the operating member 50 no longer supports the elastic member 48 (for example, the protrusion 100 of the operating member 50 and the elastic arm 56 of the elastic member 48 are longitudinally misaligned and no longer abut against each other), so that the elastic arm 56 of the elastic member 48 can leave the predetermined state S1 in response to the elastic force F1. For example, at this time, the elastic arm 56 of the elastic member 48 moves to another predetermined state S2 in response to the elastic force F1 (as shown). Figure 8 As shown), at this time, the auxiliary part 58 protrudes through the corresponding hole 68 (as shown). Figure 7 (As shown).

[0046] Preferably, when the operating member 50 is in the second operating position K2, the first predetermined portion 92 of the operating member 50 no longer presses against the second predetermined portion 94 of the button 76, causing the button 76 to respond to the auxiliary elastic member 78 by releasing the auxiliary elastic force F2 and moving laterally from the unblocked state B1 to a blocked state B2 (e.g., Figure 8 (As shown). When the operating member 50 is in the second operating position K2 and the button 76 is in the blocking state B2, the second predetermined part 94 of the button 76 blocks the first predetermined part 92 of the operating member 50, so that the operating member 50 is held in the second operating position K2, and the return elastic member 74 accumulates the return elastic force F3.

[0047] like Figure 9 As shown, the slide rail assembly 20 is in a retracted state. The second rail 24 is in a first predetermined position P1 (e.g., a retracted position) relative to the first rail 22 (and the third rail 26). Furthermore, when the operating member 50 is in the first operating position K1, the protrusion 100 of the operating member 50 supports the elastic member 48 (e.g., the protrusion 100 of the operating member 50 abuts against the elastic arm 56 of the elastic member 48), allowing the elastic arm 56 of the elastic member 48 to remain in the predetermined state S1 and accumulate the elastic force F1 (e.g., the elastic force F1) against the longitudinal wall 30 of the first rail 22. Figure 9 As shown, or may be consulted in conjunction with other resources. Figure 6 ).

[0048] It is worth mentioning that if the user needs to move the second track 24 away from the first predetermined position P1 relative to the first track 22 and to a working position W (for details on the working position W, please refer to...), Figure 12 When the second rail 24 is blocked at the working position W, this function can be activated through the operating element 50.

[0049] like Figure 9 , Figure 10 and Figure 11As shown, when the second rail 24 is in the first predetermined position P1 relative to the first rail 22, and the operating member 50 is in the first operating position K1, the control device is in a state where it has not yet been activated, and therefore does not form a working relationship with the longitudinal wall 30 of the first rail 22 (no obstruction). At this time, the user can choose to apply the predetermined force M to the operating part 98 of the operating member 50 (e.g., ...). Figure 9 As shown), the operating member 50 moves longitudinally from the first operating position K1 to the second operating position K2, and the restoring elastic member 74 accumulates the restoring elastic force F3 (as shown). Figure 10 As shown, or may be consulted in conjunction with other resources. Figure 8 When the operating member 50 is in the second operating position K2, the protrusion 100 of the operating member 50 no longer supports the elastic member 48 (for example, the protrusion 100 of the operating member 50 and the elastic arm 56 of the elastic member 48 are longitudinally misaligned and no longer abut against each other), so that the elastic arm 56 of the elastic member 48 can leave the predetermined state S1 in response to a portion of the elastic force F1, and the auxiliary part 58 on the elastic arm 56 of the elastic member 48 abuts against the wall surface of the longitudinal wall 30 of the first rail 22 (e.g. Figure 11 (As shown).

[0050] like Figure 12 and Figure 13 As shown, when the operating element 50 is in the second operating position K2, the control device is in an activated state and can form a working association (with an obstruction relationship) with the predetermined features of the default position of the longitudinal wall 30 of the first rail 22. Specifically, when the second rail 24 is displaced relative to the first rail 22 from the first predetermined position P1 in a first direction D1 to a second predetermined position P2 (e.g., a fully extended position, this part can be referred to in conjunction with the previous text)... Figure 16 During the process, the auxiliary part 58 of the elastic member 48 can block each other with a first wall segment 104 of the predetermined feature 34 to stop the second rail 24 at the working position W (that is, the second rail 24 stays at the working position W), so as to prevent the second rail 24 from displacing from the working position W to the first direction D1 to the second predetermined position P2 (e.g., Figure 12 (As shown). Specifically, the elastic arm 56 of the elastic member 48 moves to the other predetermined state S2 in response to the elastic force F1 of the other parts, causing the auxiliary part 58 to pass through the corresponding hole 68 and extend into the predetermined feature 34 of the longitudinal wall 30 of the first rail 22, and the auxiliary part 58 can block each other with the first wall segment 104 of the predetermined feature 34 (as shown). Figure 12 As shown), it is used to stop the second rail 24 in the working position W (as shown). Figure 12 and Figure 13 (As shown).

[0051] Preferably, the predetermined feature 34 further includes a second wall segment 106 positioned relative to the first wall segment 104; when the second rail 24 is in the working position W relative to the first rail 22, and the operating member 50 is in the second operating position K2, the protrusion 100 of the operating member 50 no longer supports the elastic arm 56 of the elastic member 48 (e.g., Figure 13 As shown), the elastic member 48 moves to the other predetermined state S2 in response to the elastic force F1 of the other parts, and the auxiliary part 58 and the second wall section 106 of the predetermined feature 34 block each other (as shown). Figure 12 (as shown), to prevent the second rail 24 from shifting from the working position W to a second direction D2 opposite to the first direction D1 to the aforementioned first predetermined position P1 (as shown). Figure 12 and Figure 13 (As shown).

[0052] like Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, when it is desired to release the mutual obstruction between the auxiliary part 58 of the elastic member 48 and the predetermined feature 34 of the first rail 22 in the other predetermined state S2, and to cause the second rail 24 to leave the working position W, the user can apply a pressing force Q (such as...). Figure 13 (As shown) Press the button 76 and overcome the aforementioned auxiliary spring force F2, causing the button 76 to move from the blocking state B2 (as shown) Figure 12 and Figure 13 (As shown) Returning to the unobstructed state B1, the second predetermined part 94 of the button 76 no longer obstructs the first predetermined part 92 of the operating member 50 (as shown). Figure 14 and Figure 15 As shown), the operating member 50 responds to the return elastic member 74 by releasing the return elastic force F3 from the second operating position K2 (as shown). Figure 13 (As shown) Return to the first operation position K1 (as shown) Figure 14 and Figure 15 As shown), during this process, the operating member 50 can drive the elastic arm 56 of the elastic member 48 through the guide section 102, so that the protrusion 100 of the operating member 50 can support the elastic arm 56 of the elastic member 48 again, so that the elastic arm 56 of the elastic member 48 is in the predetermined state S1 and the elastic force F1 is accumulated again (as shown). Figure 14 As shown), and the auxiliary part 58 moves away from the predetermined feature 34 of the first track 22 and fails to block the first wall segment 104 and the second wall segment 106 of the predetermined feature 34 (as shown). Figure 15As shown), to allow the second rail 24 to leave the working position W, for example, the second rail 24 may be allowed to move from the working position W to the first direction D1 to the second predetermined position P2; or, the second rail 24 may be allowed to move from the working position W to the second direction D2 to the first predetermined position P1.

[0053] like Figure 16 As shown, the slide rail assembly 20 further includes a first predetermined member 108 and a second predetermined member 110 movably mounted (e.g., pivotally connected) to the second rail 24. Preferably, it also includes at least one elastic segment, such as a first elastic segment 112 and a second elastic segment 114, for providing elastic force to the first predetermined member 108 and the second predetermined member 110, respectively. Furthermore, the operating member 50 is in the first operating position K1.

[0054] It is worth mentioning that if the user does not need the second rail 24 to be blocked in the aforementioned working position W, then the operating member 50 does not need to be operated to the second operating position K2. Furthermore, when the operating member 50 is in the first operating position K1, the protrusion 100 of the operating member 50 supports (e.g., abuts against) the elastic arm 56 of the elastic member 48, placing the elastic member 48 in the predetermined state S1. This ensures that during the displacement of the second rail 24 relative to the first rail 22 from the aforementioned first predetermined position P1 towards the first direction D1, the auxiliary portion 58 of the elastic member 48 and the first wall segment 104 of the predetermined feature 34 of the first rail 22 will not obstruct each other, allowing the second rail 24 to directly cross the predetermined feature 34 in the first direction D1 to reach the second predetermined position P2. At this time, the slide rail assembly 20 is in a fully extended state. When the slide rail assembly 20 is in the fully extended state, the second rail 24 can be engaged with the auxiliary feature 42 of the third rail 26 via the first predetermined member 108 and the second predetermined member 110, so that the second rail 24 can be held in the second predetermined position P2; in addition, the first predetermined member 108 and the second predetermined member 110 can be operated respectively via a first link 116 and a second link 118, so that the first predetermined member 108 and the second predetermined member 110 are disengaged from the auxiliary feature 42. Since this part is a technical scope that can be understood by those skilled in the art, it will not be described in detail here.

[0055] Preferably, when the second rail 24 is in the working position W relative to the first rail 22, the first end 24a of the second rail 24 extends beyond the first end 22a of the first rail 22 by a first predetermined distance X1 (e.g., ...). Figure 12 (as shown); when the second rail 24 is at the second predetermined position P2 relative to the first rail 22, the first end 24a of the second rail 24 extends beyond the first end 22a of the first rail 22 by a second predetermined distance X2 (as shown). Figure 16As shown), and the second predetermined distance X2 is greater than the first predetermined distance X1.

[0056] like Figure 17 The diagram illustrates a slide rail assembly 200 according to a second embodiment of the present invention. The difference between this second embodiment and the first embodiment is substantially that the slide rail assembly 200 does not include the aforementioned button 76 and return elastic member 74. Furthermore, when the operating member 202 is in the first operating position K1', the protrusion 204 of the operating member 202 supports the elastic arm 208 of the elastic member 206, allowing the elastic arm 208 of the elastic member 206 to remain in a predetermined state S1' and accumulate a spring force F1' towards the longitudinal wall 209 of the first rail 208.

[0057] like Figure 17 and Figure 18 As shown, the user can apply a predetermined force M1' in a predetermined operating direction to the operating part 210 of the operating member 202, causing the operating member 202 to move from the first operating position K1' (e.g., Figure 17 (As shown) move longitudinally to the second operating position K2' (e.g.) Figure 18 As shown), the protrusion 204 of the operating member 202 no longer supports the elastic arm 208 of the elastic member 206, so that the elastic arm 208 of the elastic member 206 can leave the predetermined state S1' in response to the elastic force F1'. When the second rail 212 is displaced from the first predetermined position P1 to the above-mentioned working position, the auxiliary part 207 of the elastic member 206 can be used to block each other with the predetermined feature of the first rail 208 (since this principle has been disclosed above, it will not be repeated here).

[0058] Furthermore, unlike the first embodiment where the user must press the button 76, and the operating member 50 responds to the return elastic member 74 by releasing the return elastic force F3 to return from the second operating position K2 to the first operating position K1, thereby causing the elastic arm 56 of the elastic member 48 to return from another predetermined state S2 to the predetermined state S1; in contrast, in this second embodiment, when the operating member 202 is in the second operating position K2' (e.g. Figure 18 As shown), the user can manually apply another predetermined force M2' in the opposite direction of the predetermined operation, causing the operating member 202 to move from the second operating position K2' (as shown). Figure 18 (As shown) Return to the first operation position K1' (as shown) Figure 17 (As shown).

[0059] Therefore, in the two embodiments of the present invention, taking the first embodiment as an example, the working position W is located between the first predetermined position P1 (e.g., the retracted position) and the second predetermined position P2 (e.g., the fully extended position). Specifically, when the operating member 50 is in the first operating position K1, the blocking mechanism of the second rail 24 relative to the first rail 22 in the working position W cannot be activated; when the operating member 50 is in the second operating position K2, the blocking mechanism of the second rail 24 relative to the first rail 22 in the working position W can be activated. For example, when the second rail 24 is in the first predetermined position P1 relative to the first rail 22, the user can apply a predetermined force M to the operating member 50, causing the operating member 50 to move from the first operating position K1 to the second operating position K2. The operating member 50 no longer supports the elastic member 48, causing the elastic member 48 to respond. The elastic force F1 can leave the predetermined state S1, providing a means for the second rail 24 to move relative to the first rail 22 from the first predetermined position P1 to the second predetermined position P2. During this process, the auxiliary part 58 of the elastic member 48 and the predetermined feature 34 of the first rail 22 mutually block each other, causing the second rail 24 to remain in the working position W, preventing the second rail 24 from moving from the working position W to the second predetermined position P2 in the first direction D1. This facilitates the user in performing predetermined related work procedures or maintenance operations on the second rail 24 and its supported load (e.g., electronic equipment) in the working position W. Therefore, the operating member 50 allows the user to decide whether to activate the blocking mechanism of the second rail 24 relative to the first rail 22 in the working position W as needed, providing operational selectivity.

[0060] During the process of the operating member 50 returning from the second operating position K2 to the first operating position K1, the operating member 50 can drive the elastic arm 56 of the elastic member 48 through the guide section 102, so that the protrusion 100 of the operating member 50 supports the elastic arm 56 of the elastic member 48, so that the elastic arm 56 of the elastic member 48 is in the predetermined state S1, so that the auxiliary part 58 moves away from the predetermined feature 34 of the first track 22 and fails to block each other with the predetermined feature 34 (e.g., Figure 15 As shown), this allows the second rail 24 to move away from the working position W relative to the first rail 22.

[0061] Based on the above description, it can be seen that the improved efficacy and advantages of the present invention are: it can provide users with the ability to pre-select whether to start or not start the blocking relationship between the first track 22 and the track in an extended default position, so as to make corresponding matching adjustments in response to changes in different usage scenarios.

[0062] Although the present invention has been described with reference to specific embodiments, those skilled in the art should recognize that the above embodiments are merely illustrative of the invention, and various equivalent changes and modifications can be made without departing from the spirit of the invention. Therefore, any changes or modifications to the above embodiments within the scope of the essential spirit of the invention will fall within the scope of the claims of this application.
