Description

Technical Field

[0001] This utility model relates to a slide rail assembly with a dual unlocking mechanism, specifically adapted to server cabinets, tool cabinets, and furniture. Background Technology

[0002] The slide rail assembly mainly comprises a two-section (composed of an inner frame and an outer frame) or a three-section (composed of an inner frame, a middle frame, and an outer frame) slide rail structure. The slide rail structure usually consists of one of the inner frame, middle frame, and outer frame, or each of these frames is equipped with multiple operating components to control multiple locking components, so that the inner frame is relative to the middle frame, or the middle frame is relative to the outer frame, at the end of the unfolding and closing ends. However, when the inner frame, middle frame, and outer frame slide together, the internal space available for adding functional components is extremely limited. When these frames are stacked, the remaining space in the middle cannot effectively accommodate more complex functional components. Therefore, how to avoid the problem of not being able to add functional components due to the extremely limited internal space when the inner frame, middle frame, and outer frame slide together or are stacked, and how to avoid the problem of multiple operating components controlling multiple locking components, are the directions that relevant manufacturers in this industry are eager to research and improve.

[0003] In the existing technology, the three-section slide rail structure (composed of an inner frame, a middle frame, and an outer frame) uses multiple operating components to control multiple locking components to lock the frames at their respective unfolding and retracting endpoints. However, since the multiple operating components and locking components are installed separately on the frames, when the operator unlocks the frames at their unfolding and retracting endpoints, the operator has to apply force to multiple operating components to unlock them. Therefore, how to avoid the problem of the operator having to apply force to multiple operating components when the frames are at their respective unfolding and retracting endpoints is the direction that industry professionals urgently want to research and improve. Summary of the Invention

[0004] The main purpose of this utility model is to provide a slide rail assembly with a dual unlocking mechanism. By concentrating the locking component and the operating component on the first rail, the first locking component and the second locking component can be sequentially controlled to unlock the first rail and the second rail respectively through a single operation.

[0005] To achieve the above objectives, the present invention includes a first rail, a second rail, and an operating member. The second rail is displaced relative to the first rail. A locking member is movably provided on one side of the first rail. The operating member is installed on the first rail and can drive the locking member to lock the second rail in an extended position. When the second rail is in the extended position and locked by the locking member, a force is applied to the operating member in the same direction to generate a first segment movement and a second segment movement. The first segment movement allows the locking member to enter a preparatory state, and the second segment movement allows the locking member to change from the preparatory state to an unlocked state, thereby releasing the second rail from being locked in the extended position.

This utility model is a slide rail assembly with a dual unlocking mechanism, comprising: a slide rail 1, a locking component 2, an operating component 3, a positioning component 4, a positioning feature 5, a first locking element 6, and a second locking element 7. The slide rail 1 is composed of a first rail 11, a second rail 12, and a third rail 13. The first rail 11 moves relative to the second rail 12, and the second rail 12 moves relative to the third rail 13. The second rail 12 extends the moving distance of the first rail 11 relative to the third rail 13. A locking component 2 is movably provided on one side of the first rail 11. The operating component 3 is mounted on the first rail 11. The first rail 11 has a horizontal extension... A first longitudinal wall 111 extends outwards, and a first side wall 112 bends outwards in the same direction relative to the outer side of the first longitudinal wall 111. The two first side walls 112 and the first longitudinal wall 111 form a preset space 110. The second rail 12 has a horizontally extending second longitudinal wall 122, and the second longitudinal wall 122 bends outwards in the same direction relative to the outer side of the second longitudinal wall 122 to form two second side walls 123.

Part 211, the third rail 13 has a second stop 131 protruding from one end of the first bearing part 211, the second locking member 22 has a positioning feature 5 protruding below it, the rear end of the second locking member 22 is bent away from the positioning feature 5 and extends to a limiting part 221, the elastic member 24 connects the limiting part 221 and the two first sidewalls 112 of the first rail 11, the limiting part 221 has a notch 221a on its lower side to accommodate one end of the elastic member 24, the limiting part 221 is bent away from the second rail 12 and extends to a second bearing part 221b on its upper side, the second rail 12 has a first stop 121 protruding from one end of the second bearing part 221b, and the guide member 23 is away from the first locking member. The other end of the guide member 23 is bent and extended to a third abutment 232 relative to the second locking member 22. The third abutment 232 forms a gap G with the positioning feature 5 on the second locking member 22. The guide member 23 is disposed at the end of the operating member 3. The third abutment 232 and the positioning feature 5 are in a mutually matching structure. The two ends of the elastic member 24 abut against the two first side walls 112 respectively. One end of the elastic member 24 is bent and extended to a positioning part 241 disposed on the second locking member 22. The structure, displacement, unfolding and retraction of the first rail 11, the second rail 12 and the third rail 13 are well known technologies and will not be described in detail here for the sake of simplicity.

[0084] This utility model is described using the positioning feature 5 as a pre-processed part, which is then assembled to the second locking member 22 as an example. When the positioning feature 5 is a pre-processed part, it can also be a rivet of equal height, a bolt, or other locking element, and should not be limited thereto. The positioning member 4, the first locking member 6, and the second locking member 7 can be rivets of equal height, bolts, or other locking elements, respectively. In this embodiment, the positioning member 4, the first locking member 6, and the second locking member 7 are all rivets of equal height. This embodiment is not intended to limit the patent scope of this utility model.

[0085] Please refer to Figures 3 to 5. The operating component 3 has a first sheet metal 31, a second sheet metal 32, and a displacement component 33. The displacement component 33 is disposed between the first sheet metal 31 and the second sheet metal 32. The first sheet metal 31 is fixedly arranged at one end of the first rail 11. The first sheet metal 31 is provided with a first locking component 21. A first notch 311 is opened above the rear end of the first sheet metal 31. A first fixing part 312 is bent and extended from the lower rear end of the first sheet metal 31 toward the second sheet metal 32. The second sheet metal 32 is further... A second notch 322 corresponding to the first fixing part 312 is provided below the base. One end of the displacement member 33 engages with the first fixing part 312, and the other end of the displacement member 33 engages with a third fixing part 323 of the second sheet metal 32 located in front of the second notch 322. A second fixing part 321 corresponding to the first notch 311 is bent and extended from the upper rear base of the second sheet metal 32 toward the first sheet metal 31. One end of the guide member 23 is bent and extended with a supporting part 231 inserted into the first notch 311. The supporting part 231 engages with the second fixing part 322. The fixing part 321, the rear end of the first sheet metal 31 and the rear base of the second sheet metal 32 extend outwards with a first part 313 and a second part 324, respectively. The first part 313 and the second part 324 are respectively provided with a first opening 314 and a second opening 325. The edge of the first opening 314 bends and extends horizontally toward the first rail 11 to form a first bent part 314a. The edge of the second opening 325 bends and extends horizontally toward the second rail 12 to form a second bent part 325a. 24 has a long groove 326 on the front side of the second opening 325 for a positioning member 4 to be inserted and moved. The positioning member 4 is then assembled to the first part 313 of the first sheet metal 31. The second sheet metal 32 has a first stop part 327, a second stop part 328 and a relief groove 329 on one side adjacent to the first locking member 21. The first stop part 327 and the second stop part 328 are located on opposite sides of the relief groove 329 and are misaligned. The upper end of the first locking member 21 has a protrusion 212 for the first stop part 327 to abut against.

[0086] The elastic element 24 of this utility model can be a wire spring, or a torsion spring, bending spring, or compression spring, or other element that can return to its original position after being compressed, but is not limited thereto; the displacement element 33 can be a spring, hydraulic rod, or pneumatic rod, or other element that can return to its original position after being stretched. The displacement element 33 is described using a spring (e.g., a tension spring) as an example. The example is not intended to limit the patent scope of this utility model.

[0087] Please refer to Figures 2 to 3 and Figures 6 to 7. When the operator applies force to the operating member 3 in a first direction D1, the second sheet metal 32 of the operating member 3 is subjected to force and drives the guide 23 of the locking member 2. At this time, the other abutting part 232 of the guide 23 aligns with the positioning feature 5 on the second locking member 22 of the locking member 2, forming a gap G, to generate a first movement LA. The displacement member 33 allows the second sheet metal 32 of the operating member 3 to move relative to the first sheet metal 31 in the same direction. The second part 324 of the second sheet metal 32 moves in the same direction relative to the first part 313 of the first sheet metal 31. The second sheet metal 32 disengages from the end face of the first rail 11. The second fixing part 321 of the second sheet metal 32 drives the guide 23. The guide 23, in conjunction with the supporting part 231, moves in the same direction, causing the guide 23, in conjunction with another supporting part 232, to abut against the positioning feature 5 located on the second locking member 22 to form a preparatory state. The third fixing part 323 of the second sheet metal 32 drives the other end of the displacement member 33, causing the displacement... Part 33 extends, and the second opening 325 of the second sheet metal 32 aligns with the first opening 314 of the first sheet metal 31. One end of the long groove 326 of the second sheet metal 32 disengages from the positioning member 4, one end of the other long groove 320 of the second sheet metal 32 disengages from the first locking member 6, and one end of the clearance groove 329 of the second sheet metal 32 disengages from the second locking member 7. The inclined wall 328a of the second stop portion 328 of the second sheet metal 32 pushes against the upper end of the first locking member 21, and the first stop portion 327 of the second sheet metal 32 disengages from the first locking member 21. The protrusion 212 of the component 21 causes the first locking member 21 of the locking member 2 to pivot in the opposite direction to form a first angle θ1, and the first bearing part 211 of the first locking member 21 disengages from the second stop part 131 of the third rail 13, so that the first rail 11 can be separated from a retracted position P0. When the operator applies force to the first plate 31, the first plate 31 drives the first rail 11 to move in the same direction, and the second rail 12 moves in the same direction relative to the first rail 11, so that the second rail 12 moves in the same direction relative to the third rail 13.

[0088] Please refer to Figures 3 and 11. When the second rail 12 is moved in the first direction D1 by the first rail 11, its elastic member 24 is elastically extended. The second locking member 22, located at the second bearing portion 221b of the limiting portion 221, moves in the same direction to abut against one end of the first stop portion 121 of the second rail 12. The second bearing portion 221b guides one end of the first stop portion 121, and the notch 221a of the limiting portion 221 presses against the positioning portion 241 of the elastic member 24. At this time, the elastic member 24 is elastically compressed, causing the second locking member 22 to pivot in the opposite direction to form a second angle θ2. When the second bearing portion 221b passes the first stop portion 121, the elastic member 24 elastically extends, allowing the second locking member 22 to pivot in the forward direction. The second bearing portion 221b abuts against the other end of the first stop portion 121, so that the second rail 12 is locked by the second locking member 22 at an extended position P1.

[0089] Please refer to Figures 12 and 13. When the operator stops applying force to the operating component 3 in the first direction D1, its displacement member 33 resets. The displacement member 33 drives the second sheet metal 32, causing the second sheet metal 32 to reset relative to the first sheet metal 31. The first fixing part 312 of the first sheet metal 31 drives one end of the displacement member 33, and the other end of the displacement member 33 drives the third fixing part 323 of the second sheet metal 32. The second part 324 of the second sheet metal 32 resets relative to the first part 313 of the first sheet metal 31, and the second fixing part 321 of the second sheet metal 32 drives the guide member 23 again. The guide member 23, in conjunction with the supporting part 231, moves in a second direction D2 opposite to the first direction D1. At this time, the other supporting part 232 of the guide member 23 is moved in the same direction by the guide member 23. As the second plate moves, the other supporting part 232 disengages from the positioning feature 5 and transitions from a ready state to a released ready state. The other supporting part 232 and the positioning feature 5 form a distance G again, and one end of the long groove 326 of the second plate 32 abuts against the positioning member 4 again. One end of the other long groove 320 of the second plate 32 abuts against the first locking member 6 again, and one end of the clearance groove 329 of the second plate 32 abuts against the second locking member 7 again. The inclined wall 328a of the second stop part 328 of the second plate 32 disengages from the upper end of the first locking member 21. The first stop part 327 of the second plate 32 pushes against the protrusion 212 of the first locking member 21, causing the first locking member 21 to pivot in the forward direction. The outer edge of the second part 324 of the second plate 32 abuts against the end face of the first rail 11 adjacent to the first locking member 21.

[0090] Please refer to Figures 2, 6 to 14. When the second rail 12 is in the extended position P1 and locked by the locking member 2, when the operator applies force to the operating member 3 again in the first direction D1, the second sheet metal 32 of the operating member 3 is again subjected to force and drives the locking member 2 to produce a first segment movement LA and a second segment movement LB. The components or structures and actions that cooperate with the first segment movement LA have been described in detail in the above paragraphs and will not be repeated here. At this time, the first segment movement LA provides the locking member 2 with... The guide member 23 and the positioning feature 5 located on the second locking member 22 enter the ready state. Simultaneously, the other abutting part 232 of the guide member 23 abuts against the positioning feature 5, and the first locking member 21 again forms the first angle θ1. When the second sheet metal 32 is subjected to force and moves in the second stage LB, the other end of the long groove 326 of the second sheet metal 32 abuts against the positioning member 4, and the other end of the other long groove 320 of the second sheet metal 32 abuts against the first locking member 6. The other abutting part 232 of the guide member 23 drives the positioning feature 5 located on the second locking member 22, causing... The second locking member 22 of the locking component 2 rotates in the reverse direction and changes from the ready state to an unlocked state. The second locking member 22 forms the second angle θ2 again, and the notch 221a of the limiting part 221 of the second locking member 22 presses against the positioning part 241 of the elastic member 24 again. The second bearing part 221b of the second locking member 22 disengages from the other end of the first stop 121 of the second rail 12. At this time, the elastic member 24 is elastically compressed, and the other end of the relief groove 329 of the second sheet metal 32 abuts against the second locking fastener 7 to release the second rail 12 from being locked. When the first sheet metal part 31 of the operating component 3 is positioned at the extended position P1, and the operator applies force to the first sheet metal part 31 in the second direction D2, its second bearing part 221b passes over the first stop part 121. At the same time, the first sheet metal part 31 sequentially drives the first rail 11 and the second rail 12 to continue moving in the same direction to the retracted position P0, and the force on the second sheet metal part 32 stops. The elastic member 24 elastically resets, and the second sheet metal part 32 resets in the same direction relative to the first sheet metal part 31. Other cooperating components or structures have been described in detail in the above paragraphs, and for the sake of brevity, they will not be described again here.

[0091] Please refer to Figures 5 and 15 to 17. The second plate 32 of the operating component 3 of this utility model can be linked to the first locking member 21 and the second locking member 22 respectively, so that the first locking member 21 and the second locking member 22 can pivot respectively. At this time, the first locking member 21 and the second locking member 22 respectively form a first angle θ1 and a second angle θ2, which can increase the effectiveness of the first locking member 21 and the second locking member 22 being movable in the preset space 110. The relationship between the first angle θ1 and the second angle θ2 can be designed such that the first angle θ1 is equal to the second angle θ2 (as shown in the first embodiment in Figure 15), or it can be designed such that the first angle θ1 is greater than the second angle θ2 (as shown in the second embodiment in Figure 16), so as to meet the effectiveness of different design or operation requirements. The implementation method is not intended to limit the scope of the patent.

[0092] The operating component 3 disclosed in this utility model applies force in the same direction, causing its second sheet metal 32 to sequentially move in the first segment LA and the second segment LB, and linking the first locking component 21 and the second locking component 22 to form a first angle θ1 and a second angle θ2 respectively. The relationship between the first angle θ1 and the second angle θ2 can be adjusted according to actual operational needs. Furthermore, the first locking component 21 and the second locking component 22 are pivotally connected to one side of the first rail 11, thereby simplifying the internal configuration of the first rail 11, the second rail 12, and the third rail 13. The locking component 2 and the operating component 3 are concentrated on the first rail 11. This allows for the sequential control of the first locking member 21 and the second locking member 22 to unlock the first rail 11 and the second rail 12 respectively through a single operation. Furthermore, the relationship between the first angle θ1 and the second angle θ2 expands the range of the preset space 110 of the first rail 11, thereby creating sufficient space for the addition of other complex components. This optimizes the overall structural design, enabling the slide rail assembly 1 to effectively accommodate and accommodate various and complex functional components, such as anti-deformation components, buffer components, and composite locking units, thereby maximizing the functionality of the slide rail assembly and its adaptability to complex functional products.
