Description

Technical Field

[0001] This invention relates to slide rails, and more particularly to self-closing slide rails and drawers including self-closing slide rails. Background Technology

[0002] Self-closing drawer slides contain springs and dampers. When the drawer is pushed to the almost fully closed position, the self-closing mechanism uses the spring force to automatically close the drawer. This structure allows the drawer to be pushed all the way without effort, and it also avoids the problem of the drawer not closing properly.

[0003] However, with the existing self-closing structure, when the drawer is opened, external force is required to tilt the slider so that the lever can pass over the slider and the slide rail can slide out. This results in a large starting force required to open the drawer, leading to a poor user experience. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a self-closing slide rail that requires less starting force when the slide rail is fully slid out.

[0005] To overcome the shortcomings of the prior art, a second objective of the present invention is to provide a drawer that requires less starting force when fully opened.

[0006] One of the objectives of this invention is achieved through the following technical solution:

[0007] The self-closing slide rail includes a fixed rail, a sliding rail, and a lever. The lever is fixedly connected to the sliding rail. The fixed rail has a guide groove, which includes an extension section and an inclined section. The inclined section communicates with the extension section and is angled to the extension section. The self-closing slide rail also includes a self-closing structure, which includes a first slider and a second slider. The first slider is slidably mounted in the guide groove, and the second slider is movably mounted on the first slider and slidably mounted in the guide groove. The lever drives the first slider and the second slider to slide along the guide groove. When the second slider slides to the inclined section, the inclined section causes the second slider to move relative to the first slider, thereby allowing the lever to pass over the second slider.

[0008] Furthermore, the second slider is rotatably connected to the first slider.

[0009] Furthermore, the second slider or the first slider includes a pivot, and the second slider and the first slider are rotatably connected via the pivot.

[0010] Furthermore, the fixed rail is provided with a sliding groove, the sliding groove is straight, and the rotating shaft is located in the sliding groove.

[0011] Furthermore, the second slider includes a second sliding portion and a stop portion, the stop portion being fixedly connected to the second sliding portion, and when the paddle drives the first slider and the second slider, the paddle is located between the stop portion and the first slider.

[0012] Furthermore, there are two stop portions, and the paddle is located between the two stop portions.

[0013] Furthermore, the fixed rail is also provided with a clearance groove, which is located on the side of the stop portion when the self-closing slide rail is in the closed state. The stop portion is pressed into the clearance groove by the paddle, so that the paddle returns to the position between the stop portion and the first slider.

[0014] Furthermore, the guide groove also includes a corner, which connects the extension section and the inclined section, and the corner is arc-shaped.

[0015] Furthermore, the fixed rail includes a guide rail and a bracket fixedly connected to the guide rail, and both the first slider and the second slider are slidably mounted on the bracket.

[0016] Furthermore, the bracket includes a main body and a rack, the guide rail is fixedly connected to the main body, the main body covers one side of the guide rail, the rack is fixed to the main body, and an installation space is formed between the rack and the main body. The installation space extends along the length direction of the fixed rail, and the first slider and the second slider are both slidably installed in the installation space.

[0017] Furthermore, the guide groove is disposed on the main body and / or the rack.

[0018] Furthermore, the plane containing the guide groove is parallel to the plane containing the guide rail.

[0019] Furthermore, the self-closing slide rail also includes a synchronization structure, which includes a gear and a synchronization shaft rotatably connected to the gear, the gear meshing with the rack.

[0020] Furthermore, the paddle includes a fixing part and paddle teeth. The fixing part is fixedly connected to the sliding rail, and the paddle teeth extend from the fixing part. The paddle teeth and the fixing part are located on the same plane or parallel to each other.

[0021] Furthermore, the bracket is fixed to the bottom or top of the guide rail, the guide groove is disposed on the bracket, and the plane of the guide groove is perpendicular to the plane of the guide rail.

[0022] Furthermore, the paddle includes a fixing part and a paddle tooth. The fixing part is fixedly connected to the sliding rail, and the paddle tooth extends out from the fixing part, forming an angle with the fixing part.

[0023] Furthermore, the teeth are perpendicular to the fixing part.

[0024] Furthermore, the bracket includes a mounting box and a guide member. The mounting box is fixed to the guide rail, the guide member is inserted into the mounting box, and the guide groove is disposed on the guide member.

[0025] Furthermore, the self-closing slide rail also includes an elastic element, one end of which is fixedly connected to the fixed rail, and the other end of which is fixedly connected to the first slider.

[0026] Furthermore, the self-closing slide rail also includes a damper, one end of which is fixedly connected to the fixed rail, and the other end of which is fixedly connected to the first slider.

[0027] Furthermore, the sliding rail includes a first sliding rail and a second sliding rail, the first sliding rail being slidably connected to the fixed rail, the second sliding rail being slidably connected to the first sliding rail, and the paddle being fixedly connected to the second sliding rail.

[0028] The second objective of this invention is achieved by the following technical solution:

[0029] A drawer includes a drawer body and any of the aforementioned self-closing slide rails, wherein the slide rails are fixedly connected to the drawer body.

[0030] Compared with existing technologies, the self-closing slide rail of the present invention has the following advantages:

[0031] (1) By setting the slider assembly as a separate first slider and second slider, the starting force required when the sliding rail is fully slid out is reduced, thereby improving the customer experience.

[0032] (2) The corners between the extension section and the inclined section of the guide groove are set to be arc-shaped to reduce the jamming and noise when the sliding rail is pulled out. Attached Figure Description

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] The self-closing slide rail of the present invention can automatically close the movable rail tightly by the elastic force of the elastic element when the slide rail is closed. By setting the slider as a split structure, the starting force when the slide rail is fully opened is reduced. The present application is described below through two embodiments.

[0051] Appendix Figure 1 To be continued Figure 8 This is the first embodiment of the present application:

[0052] Please see the appendix Figure 1 To be continued Figure 2 In the first embodiment, the self-closing slide rail includes a fixed rail 10, a sliding rail 20, a lever 30, a self-closing structure 40, and a synchronization structure 50. The fixed rail 10 is fixed to the device on which the slide rail is mounted, and the sliding rail 20 is slidably mounted on the fixed rail 10, allowing drawers or other components mounted on the device to slide out. The lever 30 is fixed to the sliding rail 20 and is used to deform the elastic element 42 when the sliding rail 20 is opened, accumulating the power for self-closing. The self-closing structure 40 is mounted on the fixed rail 10 and is used to make the sliding rail 20 self-close. The synchronization structure 50 is mounted on the fixed rail 10 and synchronizes the two slide rails, causing the two sides of the component to be slid out to move synchronously, increasing the smoothness of opening or closing.

[0053] The fixed rail 10 includes a guide rail 11 and a bracket 12, with the guide rail 11 and the bracket 12 fixedly connected. In this embodiment, the guide rail 11 is fixed to the equipment via the bracket 12. The bracket 12 covers one side of the guide rail 11, providing protection for the guide rail 11.

[0054] The bracket 12 includes a main body 120 and a rack 121 fixed to the main body 120. A guide rail 11 is fixed to one side of the main body 120 and located inside the main body 120. The main body 120 has a rectangular cross-section and an open structure on one side, allowing the sliding rail 20, the paddle 30, and the self-closing structure 40 to be accommodated within the main body 120. The rack 121 is fixed to the bottom of the main body 120 and extends along the length of the main body 120. A mounting space 122 is formed between the rack 121 and the main body 120. The mounting space 122 is used to mount the self-closing structure 40, and the slider assembly 41 can slide within the mounting space 122. The rack 121 meshes with the gear 51 of the synchronization structure 50 to achieve synchronization of the two parallel sliding rails. The rack 121 is provided with a clearance groove 1210, which is located at the corresponding position of the stop part 4112 of the second slider 411 when the slide rail is in the closed state. When the slide rail is in the open state, due to vibration and other reasons, the tension of the elastic element 42 causes the slider assembly 41 to disengage from the inclined section 1241 and return to the closed position, pushing the slide rail 20 inward. The paddle 30 presses the stop part 4112 and causes the stop part 4112 to deform towards the clearance groove 1210 (deform to the side), so that the paddle 30 passes over the stop part 4112 and returns to the groove 4113, restoring the closed state and performing self-rescue to avoid failure of the self-closing structure 40.

[0055] Please continue reading. Figure 3 as well as Figure 4The bracket 12 is also provided with a sliding groove 123 and a guide groove 124. The sliding groove 123 and the guide groove 124 are disposed on the rack 121 and / or the main body 120. In this embodiment, both the rack 121 and the main body 120 are provided with sliding grooves 123 and guide grooves 124 to enhance the sliding stability of the slider assembly 41 and prevent the slider assembly 41 from disengaging from the guide groove 124. The plane containing the sliding groove 123 and the guide groove 124 is parallel to the plane containing the guide rail 11. The sliding groove 123 is straight and extends along the length of the bracket 12. The sliding groove 123 is used to install the rotating shaft 4103. When the sliding rail 20 slides, the rotating shaft 4103 slides along the sliding groove 123. When the rotating shaft 4103 slides to the end of the sliding groove 123, the first slider 410 slides to the inclined section 1241. The inclined section 1241 causes the first slider 410 to rotate, and the rotating shaft 4103 rotates at the end of the sliding groove 123. The guide groove 124 includes an extension 1240 and an inclined section 1241. The extension 1240 is straight and parallel to the slide groove 123. The inclined section 1241 extends from the end of the extension 1240 and communicates with it. The inclined section 1241 and the extension 1240 are angled together, allowing the first slider 410 to move relative to the second slider 411. In this embodiment, the inclined section 1241 is perpendicular to the extension 1240, and the first slider 410 rotates relative to the second slider 411. A corner 1243 is formed at the connection between the inclined section 1241 and the extension 1240. The corner 1243 is arc-shaped. The arc design reduces the resistance when the first slider 410 slides from the extension 1240 to the inclined section 1241, avoiding jamming and noise caused by jamming.

[0056] Please continue reading. Figure 2 In this embodiment, the sliding rail 20 has a two-section structure, including a first sliding rail 21 and a second sliding rail 22. The first sliding rail 21 is slidably mounted on the guide rail 11, and the second sliding rail 22 is slidably mounted on the first sliding rail 21.

[0057] Please continue reading. Figure 5 The paddle 30 is fixed to the slide rail 20. In this embodiment, the paddle 30 is fixed to the second slide rail 22. The paddle 30 includes a fixing part 31 and paddle teeth. The paddle teeth extend from the bottom of the fixing part 31, and the paddle teeth and the fixing part 31 are located on the same plane or parallel to each other. There are two paddle teeth, namely a first paddle tooth 32 and a second paddle tooth 33. The first paddle tooth 32 and the second paddle tooth 33 are spaced apart, forming a gap 34 between them. The two-paddle-tooth design can effectively prevent the slider assembly 41 from disengaging from the inclined section 1241 due to vibration or other reasons when the slide rail is in the pulled-out state.

[0058] Please continue reading. Figure 2 as well as Figure 5The self-closing structure 40 includes a slider assembly 41, an elastic element 42, and a damper 43. One end of the elastic element 42 is fixed to the slider assembly 41, and the other end of the elastic element 42 is fixed to the fixed rail 10. The elastic force of the elastic element 42 causes the slider assembly 41 to drive the sliding rail 20 to self-close via the paddle 30.

[0059] The slider assembly 41 is a split structure, comprising a first slider 410 and a second slider 411. The first slider 410 includes a first sliding portion 4101, a first guide post 4102, and a rotating shaft 4103. Both the first guide post 4102 and the rotating shaft 4103 extend from the first sliding portion 4101. The first guide post 4102 is located in the extension 1204 of the guide groove 124, which guides the sliding direction of the first slider 410. The ends of the elastic element 42 and the damper 43 are fixed to the first slider 410. In this embodiment, the first slider 410 only slides linearly and does not rotate.

[0060] The second slider 411 is movably mounted on the first slider 410. In this embodiment, the second slider 411 not only slides together with the first slider 410, but also moves relative to the first slider 410, causing the paddle 30 to pass over the stop portion 4112. In this embodiment, the second slider 411 is rotatably mounted on the first slider 410 via a pivot 4103, and the second slider 411 rotates relative to the first slider 410. The second slider 411 includes a second sliding portion 4110, a second guide post 4111, and a stop portion 4112, both of which extend from the second sliding portion 4110. There are two stops 4112, and a groove 4113 is formed between the two stops 4112, in which the paddle 30 is located. The second guide post 4111 is located in the guide groove 124. When the second guide post 4111 moves along the extension section 1240, the second slider 411 slides in a straight line together with the first slider 410. When the second guide post 4111 moves along the inclined section 1241, the second slider 411 rotates relative to the first slider 410, thereby lowering the height of the stop part 4112 away from the first slider 410. The paddle 30 passes over the stop part 4112, and the sliding rail 20 can be fully opened.

[0061] Please continue reading. Figures 6 to 8 When using self-closing slide rails, such as Figure 6 as well as Figure 7As shown, the slide rail is initially in a closed state, with the paddle 30 located in the groove 4113, and both the first slider 410 and the second slider 411 located in the extension section 1240. When an external force is applied to the slide rail 20, the paddle 30 drives the first slider 410 and the second slider 411 to slide along the extension section 1240. When the first slider 410 slides to the corner 1243, the second slider 411 begins to rotate relative to the first slider 410. At this time, the second slider 411 enters the inclined section 1241 and is locked by the inclined section 1241, as shown. Figure 8 As shown, due to the rotation of the second slider 411, the height of the stop portion 4112, which is away from the first slider 410, decreases, and the paddle 30 passes over the stop portion 4112, allowing the slide rail 20 to be fully extended. During the sliding process of the slider assembly 41, the elastic element 42 (spring) is stretched, and when the second slider 411 is locked by the inclined section 1241, the elastic element 42 remains in a stretched state.

[0062] When the slide rail is closed, the slide rail 20 retracts under the action of external force. When the lever 30 moves to the second slider 411, the lever 30 abuts against the stop part 4112 near the first slider 410, causing the first slider 410 to reverse. The second guide post 4111 disengages from the inclined section 1241. Under the pulling force of the elastic member 42, the first slider 410 and the second slider 411 move along the extension section 1240 to reset. The lever 30 drives the slide rail 20 to close automatically. At this time, the damper 43 works to slow down the self-closing speed of the slide rail 20, preventing hand pinching and impact and noise caused by excessive speed.

[0063] Appendix Figure 9 To be continued Figure 13 This is the second embodiment of the present application:

[0064] In the second embodiment, the structure of the self-closing slide rail is largely the same as that of the first embodiment, except for the structure of the bracket 12 and the lever 30. In the second embodiment, the self-closing slide rail does not include the synchronization structure 50.

[0065] Please continue reading. Figure 9 as well as Figure 10 The bracket 12 is fixed to the top or bottom of the guide rail 11. In this embodiment, the bracket 12 is fixed to the bottom of the guide rail 11. The bracket 12 includes a mounting box 125 and a guide member 126. The mounting box 125 is fixed to the bottom of the guide rail 11, and the guide member 126 is fixed inside the mounting box 125. The mounting box 125 protects the guide member 126. Specifically, the mounting box 125 is provided with a first mounting groove 1250, and the guide member 126 is inserted into the first mounting groove 1250.

[0066] Please continue reading. Figure 10 as well as Figure 11The guide member 125 is provided with a sliding groove 123 and a guide groove 124. The planes of the sliding groove 123 and the guide groove 124 are perpendicular to the plane of the guide rail 11. Specifically, the guide member 126 includes a top plate 1260, a bottom plate 1261, a first side plate 1264, and a second side plate 1265. The slider assembly 41 is installed between the top plate 1260 and the bottom plate 1261, and the sliding groove 123 and the guide groove 124 are disposed on the top plate 1260 and the bottom plate 1261. The top plate 1260 is provided with a clearance groove 1263, which is located at the corresponding position of the stop part 4112 of the second slider 411 when the slide rail is in the closed state. When the slide rail is in the open state, due to vibration and other reasons, the tension of the elastic member 42 causes the slider assembly 41 to disengage from the inclined section 1241 and return to the closed position, pushing the slide rail 20 inward. The paddle 30 presses the stop part 4112, and the paddle 30 causes the stop part 4112 to deform towards the clearance groove 1210 (upward deformation), so that the paddle 30 passes over the stop part 4112 and returns to the groove 4113, restoring the closed state and performing self-rescue to prevent the self-closing structure 40 from failing. A second mounting groove 1266 is formed between the first side plate 1264 and the second side plate 1265. The second mounting groove 1266 is used to install the damper 43. One end of the elastic member 42 is fixed to the end of the second side plate 1265, and the other end of the elastic member 42 is fixed to the first slider 410.

[0067] The paddle 30 includes a fixing part 31 and paddle teeth. The paddle teeth extend from the bottom of the fixing part 31 and form an angle with the fixing part 31. In this embodiment, the paddle teeth are perpendicular to the fixing part 31.

[0068] Please continue reading. Figure 12 as well as Figure 13 The slide rail is initially in a closed state, with the paddle 30 positioned in the groove 4113, and both the first slider 410 and the second slider 411 located in the extension section 1240. When an external force is applied to the slide rail 20, the paddle 30 causes the first slider 410 and the second slider 411 to slide along the extension section 1240. When the first slider 410 slides to the corner 1243, the second slider 411 begins to rotate relative to the first slider 410. At this point, the second slider 411 enters the inclined section 1241 and is locked by it. As the second slider 411 rotates, the stop portion 4112, which is away from the first slider 410, retracts inward, and the paddle 30 passes over the stop portion 4112, allowing the slide rail 20 to be fully opened. During the sliding of the slider assembly 41, the elastic element 42 (spring) is stretched. When the second slider 411 is locked by the inclined section 1241, the elastic element 42 remains stretched.

[0069] When the slide rail is closed, the slide rail 20 retracts under the action of external force. When the lever 30 moves to the second slider 411, the lever 30 abuts against the stop part 4112 near the first slider 410, causing the first slider 410 to reverse. The second guide post 4111 disengages from the inclined section 1241. Under the pulling force of the elastic member 42, the first slider 410 and the second slider 411 move along the extension section 1240 to reset. The lever 30 drives the slide rail 20 to close automatically. At this time, the damper 43 works to slow down the self-closing speed of the slide rail 20, preventing hand pinching and impact and noise caused by excessive speed.

[0070] The self-closing slide rail of the present invention reduces the starting force required when the slide rail 20 is fully extended by setting the slider assembly 41 as a split first slider 410 and second slider 411, thereby improving the customer experience; and sets the corner 1243 between the extension section 1240 and the inclined section 1241 of the guide groove 124 as an arc shape to reduce the jamming and noise when the slide rail 20 is pulled out.

[0071] The present invention also discloses a drawer, which includes a drawer body and the aforementioned self-closing slide rail, wherein the slide rail 20 is fixedly connected to the drawer body.

[0072] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
