Description

Technical Field

[0001] This utility model relates to drawer slides, and in particular to a control mechanism for drawer slides. Background Technology

[0002] Drawer slides are designed to enhance drawer functionality and user experience. Specifically, these slides ensure drawers open and close smoothly and quietly, improving the user experience. They also provide sufficient support to bear the weight of items inside the drawer. To prevent drawers from accidentally sliding out or falling off, the slides feature a locking mechanism that also provides a push-to-release function, allowing the drawer to be removed from the slide.

[0003] Traditional drawer lock designs secure the drawer to the inner rail of the slide rail, which has springs on it. When the drawer is fully open, the springs on the center rail and the inner rail engage with each other to prevent the drawer from sliding off the rail. Pressing the springs releases the engagement, allowing the drawer to be removed from the slide rail.

[0004] However, due to the design of the spring mechanism, there are issues with elastic fatigue and poor pressing feel. As usage time increases, the spring's elasticity weakens, causing the drawer to not properly lock when fully opened, increasing the risk of the drawer falling out. Utility Model Content

[0005] The purpose of this utility model is to provide a control mechanism for drawer slides, mainly to solve one or more of the problems mentioned above.

[0006] To achieve the aforementioned objective, this utility model discloses a control mechanism for a drawer slide rail, comprising a middle rail; an inner rail slidably disposed on the middle rail and having a top abutment; and a pressing member disposed on the middle rail, having a fixing part fixedly disposed on the middle rail, a stop part located on one side of the fixing part for stopping or disengaging from the top abutment, and a pressing part located on the other side of the fixing part and connected to and driving the stop part. The pressing part is operable between a normal position and a released position. When the pressing part is in the normal position, the stop part stops the top abutment, preventing the inner rail from disengaging from the middle rail. When the pressing part is in the released position, the stop part disengages from the top abutment, allowing the inner rail and the middle rail to disengage from each other.

[0007] The advantage of this invention lies in the combination of the inner rail's abutment structure and the design of the pressing component. When the pressing part of the pressing component is pressed, the stop part of the pressing component will move in tandem, allowing the stop part and the inner rail's abutment to correspond or misalign. This structural design effectively achieves stable engagement or disengagement of the inner rail and the middle rail, preventing accidental detachment. Therefore, this design not only solves the performance degradation problem caused by the pressing component's elasticity fatigue but also improves the pressing feel during operation, enhancing the user experience.

[0008] Preferably, the middle rail has a first outer side and a first inner side opposite to the first outer side; the inner rail has a second outer side facing the first inner side, a second inner side opposite to the second outer side, and a top protruding from the second outer side toward the first inner side.

[0009] Preferably, the middle rail also has a first end and a second end opposite to the first end, the abutment of the inner rail is located between the first end and the second end, the fixing part of the pressing member is fixed to the first end, the stop part of the pressing member is located between the first end and the abutment, and the pressing part of the pressing member is located outside the first end.

[0010] Preferably, the middle rail also has a through hole that passes through the first outer side and the first inner side, the fixing part of the pressing member is fixed to the first outer side of the middle rail, and the stop part of the pressing member passes through the through hole and partially protrudes from the first inner side.

[0011] Preferably, the top of the inner rail has a top surface facing the first end and an arc surface opposite to the top surface, and the stop portion of the pressing member has a stop surface facing the top surface and a guide slope opposite to the stop surface.

[0012] Preferably, the pressing member has two stop portions, each stop portion is connected to the pressing portion by a connecting arm, and the two connecting arms are located on both sides of the fixing portion. The pressing portion is connected to the fixing portion by a connecting portion, and there is a gap between the two connecting arms, the fixing portion, and the connecting portion.

[0013] Preferably, a reinforcing rib is provided between the pressing part and each of the connecting arms. Attached Figure Description

[0055] See Figures 1 to 5 As shown in the figure, the drawer slide control mechanism provided in this embodiment of the present invention is suitable for fixing a drawer body 12 within a cabinet 11. The drawer slide control mechanism mainly consists of an outer rail 20, a middle rail 30, an inner rail 40, and a pressing member 50, wherein:

[0056] The outer rail 20 is fixed to the inner side of the cabinet 11.

[0057] The middle rail 30 is slidably mounted on the outer rail 20 along a sliding direction X and is shaped along the sliding direction X. The middle rail 30 has a first end 31, a second end 32 disposed along the sliding direction X and opposite to the first end 31, a first outer side 33, a first inner side 34 opposite to the first outer side 33, and two through holes 35 passing through the first outer side 33 and the first inner side 34 and adjacent to the first end 31.

[0058] The inner rail 40 slides on the middle rail 30 and is provided for the drawer body 12. The inner rail 40 has a second outer side 41 facing the first inner side 34, a second inner side 42 opposite to the second outer side 41, and a top abutment 43 protruding from the second outer side 41 toward the first inner side 34 and located between the first end 31 and the second end 32. The top abutment 43 has an L-shaped cross section and has a top abutment surface 431 facing the first end 31 and an arc surface 432 opposite to the top abutment surface 431.

[0059] The pressing member 50 is disposed on the central rail 30 and has a fixing part 51 fixed to the central rail 30, a stop part 52 located on one side of the fixing part 51 for stopping or disengaging from the abutment top 43, and a pressing part 53 located on the other side of the fixing part 51 and connected to and driving the stop part 52. The pressing part 53 can be in a normal position (e.g., Figure 5 ) and a release position (such as Figure 6 When the pressing part 53 is in the normal position, the stop part 52 blocks the top 43 of the inner rail 40 (e.g., when the pressing part 53 is in the normal position). Figure 5 This prevents the inner rail 40 from disengaging from the middle rail 30. When the pressing part 53 is in the released position, the stop part 52 disengages from the top 43 of the inner rail 40 (e.g., Figure 6 This allows the inner rail 40 and the middle rail 30 to disengage from each other. In this embodiment, the fixing part 51 of the pressing member 50 is fixed to the first end 31 of the middle rail 30 by a fixing member 60. The stop part 52 of the pressing member 50 is located between the first end 31 of the middle rail 30 and the abutment 43 of the inner rail 40. The stop part 52 passes through the through hole 35 of the middle rail 30 and partially protrudes from the first inner side surface 34 of the middle rail 30. The stop part 52 has a stop surface 521 facing the abutment surface 431 of the inner rail 40 and a guide slope 522 opposite to the stop surface 521. The pressing part 53 of the pressing member 50 is located outside the first end 31 of the middle rail 30. It also has a reset slope 531, which is inclined in the same direction as the guide slope 522, but with a different slope. In addition, the pressing member 50 has two stop portions 52, and each stop portion 52 is connected to the pressing portion 53 by a connecting arm 54. The two connecting arms 54 are located on both sides of the fixing portion 51. The pressing portion 53 is connected to the fixing portion 51 by a connecting portion 55. There is a gap 56 between the two connecting arms 54, the fixing portion 51, and the connecting portion 55. A reinforcing rib 57 is provided between the pressing portion 53 and each connecting arm 54 to increase the connection strength between the pressing portion 53 and each connecting arm 54.

[0060] The above describes the structure and configuration of the main components of this utility model embodiment. The operation and effects of this utility model are explained below.

[0061] See Figure 2A and Figure 5 As shown, when the pressing part 53 of the pressing member 50 is not pressed and is in the normal position, the stop part 52 of the pressing member 50 corresponds to the abutment top 43 of the inner rail 40. That is, the stop surface 521 of the stop part 52 and the abutment surface 431 of the abutment top 43 correspond to each other in the sliding direction X. Therefore, when the inner rail 40 is pulled to the left along the sliding direction X, the abutment top 43 of the inner rail 40 is stopped by the stop part 52 of the pressing member 50 on the middle rail 30, so that the inner rail 40 cannot be separated from the middle rail 30.

[0062] See Figure 2A , Figure 6 and Figure 7 As shown, when the pressing part 53 of the pressing member 50 is pressed and in the released position, the stop part 52 of the pressing member 50 is driven by the pressing part 53, causing the stop part 52 to move from the first inner side 34 of the middle rail 30 toward the first outer side 33. This causes the stop surface 521 of the stop part 52 and the abutment surface 431 of the abutment top 43 to be misaligned in the sliding direction X. Therefore, when the inner rail 40 is pulled to the left along the sliding direction X, the abutment top 43 of the inner rail 40 will not be stopped by the stop part 52 of the pressing member 50 on the middle rail 30, allowing the inner rail 40 to disengage from the middle rail 30, thus completing the removal of the drawer body 12.

[0063] As explained above, by combining the structure of the abutment 43 of the inner rail 40 with the design of the pressing member 50, when the pressing part 53 of the pressing member 50 is pressed, the stop part 52 of the pressing member 50 will move in tandem, allowing the stop part 52 and the abutment 43 of the inner rail 40 to correspond or misalign. This structural design effectively achieves stable engagement or disengagement of the inner rail 40 and the middle rail 30, preventing accidental detachment. Therefore, this design not only solves the performance degradation problem caused by elastic fatigue of the pressing member 50, but also improves the pressing feel during operation and enhances the user experience.

[0064] It is worth mentioning that when the fixing part 51 of the pressing member 50 is fixed to the first end 31 of the middle rail 30, the pressing part 53 of the pressing member 50 is located outside the first end 31 of the middle rail 30 and is suspended. Therefore, the pressing member 50 can be pressed more smoothly and without obstruction, which effectively improves the pressing feel during operation and enhances the user experience.

[0065] In addition, the pressing part 53 of the pressing member 50 is connected to the stop part 52 through the two connecting arms 54. Therefore, the linkage between the pressing part 53 and the stop part 52 is clear and direct, which effectively improves the operating feel. At the same time, the design of having a gap 56 between the two connecting arms 54 and the fixed part 51 and the connecting part 55 reduces the problem of elastic fatigue between the pressing part 53 and the fixed part 51 of the pressing member 50, and effectively improves the service life of the pressing member 50.

[0066] On the other hand, see Figure 6 and Figure 8 As shown, when the pressing part 53 of the pressing member 50 is pressed, in addition to causing the stop part 52 and the abutment part 43 to be misaligned relative to each other in the sliding direction X (e.g. Figure 6 Secondly, the stop part 52 will be rotated outward at an angle from an inward-facing position to an outward-facing position (e.g. Figure 8 This allows the inner rail 40 to be pulled to the left and disengaged from the middle rail 30 (e.g., Figure 7 During the continuous pulling of the inner rail 40, since the top 43 of the inner rail 40 is already located to the left of the stop 52 of the pressing member 50, there is no stop interference between the two. Therefore, it is not necessary to continuously press the pressing part 53 of the pressing member 50. Thus, this utility model only requires a single pressing operation to complete the separation of the inner rail 40 from the middle rail 30, achieving a simple operation effect. It is worth noting that when the inner rail 40 is separated from the middle rail 30 and then reassembled, refer to... Figure 9 As shown, the inner rail 40 slides to the right along the sliding direction X. At this time, the arc surface 432 of the top abutment 43 of the inner rail 40 pushes against the reset slope 531 of the pressing part 53 of the pressing member 50, so that the pressing member 50, with the fixing part 51 as the center, makes the pressing part 53 slightly lower and the stop part 52 slightly higher. As the inner rail 40 continues to slide to the right, the arc surface 432 of the top abutment 43 of the inner rail 40 then pushes against the guide slope 522 of the stop part 52 of the pressing member 50, so that the top abutment 43 of the inner rail 40 is located to the right of the stop part 52 of the pressing member 50 (e.g., Figure 5 This is to complete the reconnection of the inner rail 40 and the middle rail 30.

[0067] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
