Description

Technical Field

[0001] This invention relates to a rebound device, specifically to a synchronous rebound device and drawer for furniture. Background Technology

[0002] Drawers are now widely used in furniture. The drawer's sides are mounted on guide rails, and users manually apply pulling and pushing forces to move the drawer along these rails, thus opening and closing it. With continuous technological advancements, existing drawers offer increasingly more functions. For example, adding damping buffers to the guide rails can prevent the drawer from colliding with the furniture due to inertia when closing, protecting both the drawer and the furniture while also reducing noise. However, because current drawers require manual operation to pull out and push in, this structure cannot achieve an automatic pop-out function when pressed. This makes the drawer's function limited, extremely inconvenient to use, and time-consuming and laborious, severely impacting the user experience and convenience. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a synchronous rebound device for furniture. The synchronous rebound device can make the drawer pop out automatically by pressing the drawer, which is easy to operate and can give users a good user experience.

[0004] A second objective of this invention is to provide a drawer that utilizes the aforementioned synchronous rebound mechanism for furniture.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0006] A synchronized rebound mechanism for furniture includes a housing, a rebound push block disposed within the housing, and a reverse push device for driving the rebound push block to move in the opposite direction to drive a drawer to pop out in the opposite direction.

[0007] The rebound push block is slidably connected inside the housing, and the rebound push block can move along the length direction of the housing; the rebound push block includes a sliding buckle and a hook groove provided on the upper end of the sliding buckle for connecting with the drawer;

[0008] The reverse-push device includes a rack drive block, a reverse drive shaft, and a trigger mechanism for locking and unlocking the reverse drive shaft, all mounted on the housing. The rack drive block is mounted on the housing and is movable along its length. A sliding buckle is rotatably connected to the rack drive block. The rack drive block is connected to the front end of the housing via a tension spring. The reverse drive shaft is rotatably connected to the end of the housing, and a torsion spring is provided between the reverse drive shaft and the housing. The rack drive block has protruding teeth, and the reverse drive shaft has a gear that engages with the protruding teeth; the gear is mounted on the reverse drive shaft. When the drawer is closed, the sliding buckle and the rack drive block drive the reverse drive shaft to rotate until the trigger mechanism locks the reverse drive shaft. When the trigger mechanism is triggered, the reverse drive shaft reverses and resets under the action of the torsion spring, driving the rack drive block to separate from the gear. The rack drive block, along with the sliding buckle, moves in the opposite direction under the drive of the tension spring to open the drawer.

[0009] Preferably, a sliding guide mechanism is provided between the sliding buckle and the housing. The sliding guide mechanism includes a slide groove and a circular slider on the sliding buckle that cooperates with the slide groove. The slide groove includes an arc-shaped segment at the front end of the housing and a horizontal segment at the rear end of the housing. The arc-shaped segment is inclined downwards, and the horizontal segment extends straight along the length of the housing. When the circular slider in the sliding buckle enters the arc-shaped segment, the sliding buckle rotates downwards, allowing the drawer to disengage from the hook groove of the sliding buckle. When the circular slider in the sliding buckle enters the horizontal segment, the sliding buckle rotates upwards, causing the hook groove of the sliding buckle to engage the drawer.

[0010] Preferably, there are two sets of circular sliders, and the two sets of circular sliders are arranged in a straight line.

[0011] Preferably, a guide mechanism is provided between the rack drive block and the housing. The guide mechanism includes guide blocks disposed on the upper and lower sides of the rack drive block and guide grooves disposed on the upper and lower sides of the housing. The guide grooves extend along the length direction of the housing, and the guide blocks on the upper and lower sides are respectively installed in the guide grooves on the upper and lower sides.

[0012] Preferably, the housing includes a mounting base and a mounting cover, the mounting cover is mounted on the mounting base by a bolt connection structure, and a positioning structure is provided between the mounting base and the mounting cover.

[0013] Preferably, the positioning structure includes a positioning post and a positioning hole that mates with the positioning post.

[0014] Preferably, the mounting cover has a clearance groove at the connection between the drawer and the sliding buckle, and the clearance groove extends along the length direction of the housing.

[0015] Preferably, the triggering mechanism includes a trigger block disposed on the reversing drive shaft and a locking block disposed on the housing, wherein the locking block is rotatably connected to the housing and has a locking groove; the trigger block is provided with a first locking part and a second locking part; the outer side of the first locking part is a first arc segment, and its center is located on the axis of the reversing drive shaft; the side of the locking block that contacts the first arc segment is provided with a second arc segment, the curvature of the second arc segment is the same as that of the first arc segment, and its center is also located on the axis of the reversing drive shaft; when the reversing drive shaft rotates to the point where the second arc segment of the locking block contacts the first arc segment of the first locking part... When the arc segment separates, the locking block rotates to a vertical position under its own gravity; when the driving force of the rack drive block disappears, the reverse drive shaft rotates in the opposite direction, and the first locking part hooks into the locking groove of the locking block to lock the reverse drive shaft; when the rack drive block drives the reverse drive shaft to continue rotating, the first locking part leaves the locking groove of the locking block; the second locking part drives the locking block to rotate in the opposite direction to a horizontally upward posture; when the driving force of the rack drive block disappears, the reverse drive shaft rotates in the opposite direction, and the first arc segment outside the first locking part and the second arc segment of the locking block cooperate to release the reverse drive shaft.

[0016] Preferably, the locking block also has a groove with the same structure as the locking groove on the side opposite to the locking groove.

[0017] A drawer including a synchronized rebound mechanism for use with the aforementioned furniture.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The synchronous rebound mechanism for furniture of the present invention, when the drawer is closed, drives the sliding latch and rack and pinion drive block to move through the drawer, thereby causing the teeth on the rack and pinion drive block to engage with the gear, thereby driving the gear and the reverse drive shaft to rotate until the trigger mechanism locks the reverse drive shaft; when it is necessary to open the drawer, it is only necessary to trigger the trigger mechanism. When the trigger mechanism is triggered, the reverse drive shaft reverses and resets under the action of the torsion spring to drive the rack and pinion drive block to separate from the gear, and the rack and pinion drive block together with the sliding latch drive the drawer to move in the opposite direction under the drive of the tension spring to open the drawer.

[0032] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0033] See Figures 1-10 The synchronous rebound device for furniture of the present invention includes a housing 1, a rebound push block disposed in the housing 1, and a reverse push device for driving the rebound push block to move in the opposite direction to drive the drawer to pop out in the opposite direction.

[0034] See Figures 1-10The rebound push block is slidably connected inside the housing 1, and the rebound push block can move along the length direction of the housing 1; the rebound push block includes a sliding buckle 2 and a hook groove 201 for connecting with a drawer disposed on the upper end of the sliding buckle 2; a sliding track changing mechanism is provided between the sliding buckle 2 and the housing 1, the sliding track changing mechanism includes a slide groove 104 and a circular slider 202 disposed on the sliding buckle 2 and cooperating with the slide groove 104, wherein the slide groove 104 includes an arc-shaped segment disposed at the front end of the housing 1 and a horizontal segment disposed at the rear end of the housing 1, wherein the arc-shaped segment is inclined downward; the horizontal segment extends straight along the length direction of the housing 1; when the sliding buckle 2 When the circular slider 202 enters the arc-shaped section (i.e., during the opening of the drawer), the sliding buckle 2 rotates downward, causing the hook groove 201 in the sliding buckle 2 to change from a vertical state to a horizontal state, thereby allowing the drawer to disengage from the hook groove 201 of the sliding buckle 2, and the drawer can continue to open; when the circular slider 202 in the sliding buckle 2 enters the horizontal section (i.e., during the closing of the drawer), the sliding buckle 2 rotates upward, causing the hook groove 201 in the sliding buckle 2 to change from a horizontal state to a vertical state, thereby causing the hook groove 201 of the sliding buckle 2 to hook the drawer, and the drawer continues to close, which pushes the sliding buckle 2 and the rack and pinion drive block 3 to move in the direction of the reverse drive shaft 8.

[0035] In this embodiment, there are two sets of circular sliders 202, and the two sets of circular sliders 202 are arranged in a straight line.

[0036] See Figures 1-10 The reverse thrust device includes a rack drive block 3 mounted on the housing 1, a reverse drive shaft 8, and a trigger mechanism for locking and unlocking the reverse drive shaft 8.

[0037] The rack drive block 3 is mounted on the housing 1 and can move along the length of the housing 1. A guide mechanism is provided between the rack drive block 3 and the housing 1. The guide mechanism includes guide blocks 302 disposed on the upper and lower sides of the rack drive block 3 and guide grooves 103 disposed on the upper and lower sides of the housing 1. The guide grooves 103 extend along the length of the housing 1, and the guide blocks 302 on the upper and lower sides are respectively installed in the guide grooves 103 on the upper and lower sides. By setting the guide mechanism, the movement of the rack drive block 3 is guided, thereby improving its movement accuracy.

[0038] The sliding buckle 2 is rotatably connected to the rack drive block 3; the rack drive block 3 is connected to the front end of the housing 1 via a tension spring 4; the reverse drive shaft 8 is rotatably connected to the end of the housing 1; and a torsion spring 5 is provided between the reverse drive shaft 8 and the housing 1; the rack drive block 3 is provided with a tooth 301, and the reverse drive shaft 8 is provided with a gear 6 that engages with the tooth 301, and the gear 6 is mounted on the reverse drive shaft 8; during the process of closing the drawer, the sliding buckle 2 and the rack drive block 3 drive the reverse drive shaft 8 to rotate until the trigger mechanism locks the reverse drive shaft 8; when it is necessary to open the drawer, it is only necessary to trigger the trigger mechanism. When the trigger mechanism is triggered, the reverse drive shaft 8 reverses and resets under the action of the torsion spring 5 to drive the rack drive block 3 to separate from the gear 6, and the rack drive block 3 together with the sliding buckle 2 drives the drawer to move in the opposite direction under the drive of the tension spring 4 to open the drawer;

[0039] In this embodiment, the triggering mechanism includes a trigger block 9 disposed on the reversing drive shaft 8 and a locking block 7 disposed on the housing 1. The locking block 7 is rotatably connected to the housing 1 and has a locking groove 701. The trigger block 9 is provided with a first locking part 901 and a second locking part 902. The outer side of the first locking part 901 is a first arc segment 904, and its center is located on the axis of the reversing drive shaft 8. The side of the locking block 7 that contacts the first arc segment 904 is provided with a second arc segment 702. The curvature of the second arc segment 702 is the same as that of the first arc segment 904, and its center is also located on the axis of the reversing drive shaft 8. On the axis of the reverse drive shaft 8; during the closing process of the drawer, the rack drive block 3 drives the gear 6 and the reverse drive shaft 8 to rotate until the second arc segment 702 of the locking block 7 separates from the first arc segment 904 of the first locking part 901. At this time, the locking block 7 rotates to a vertical position under its own gravity. The locking groove 701 of the locking block 7 is located within the movement trajectory of the first locking part 901. When the driving force of the rack drive block 3 disappears, under the tension of the tension spring 4, the rack drive block 3 drives the reverse drive shaft 8 to return to its original position by a small distance, causing the reverse drive shaft 8 to rotate in the opposite direction, thereby allowing the drawer to... The first locking part 901 hooks into the locking groove 701 of the locking block 7, thereby locking the reverse drive shaft 8. When the drawer needs to be opened, simply push the drawer inward, causing the rack and pinion drive block 3 to drive the reverse drive shaft 8 to continue rotating. At this time, the second locking part 902 drives the locking block 7 to rotate in the opposite direction, while simultaneously causing the first locking part 901 to leave the locking groove 701 of the locking block 7, and the first arc segment 904 on the outer side of the first locking part 901 to abut against the second arc segment 702 of the locking block 7. As the reverse drive shaft 8 continues to rotate, the second locking part 902 begins to push the locking block 7 to rotate to... The rack and pinion drive block 3 is positioned horizontally upwards to facilitate its entry into the limiting groove 903. When the driving force of the rack and pinion drive block 3 disappears (i.e., the drawer stops being pushed inwards), the reverse drive shaft 8 quickly rotates in the opposite direction under the elastic force of the torsion spring 5. The first locking part 901 slides on the second arc segment 702 of the locking block 7, thereby releasing the reverse drive shaft 8 and allowing the rack and pinion drive block 3 to move outwards until it separates from the gear 6. At this time, the locking block 7 enters the limiting groove 903. Then, under the tension of the tension spring 4, the rack and pinion drive block 3 and the sliding buckle 2 move outwards, thereby driving the drawer to move outwards to open the drawer.

[0040] The locking block 7 also has a groove 703 with the same structure as the locking groove 701 on the side opposite to the locking groove 701; this makes it easier for the second locking part 902 to drive the locking block 7 to rotate in the opposite direction.

[0041] See Figures 1-10 The trigger block 9 is also provided with a limiting groove 903. The limiting groove 903 is located on the outside of the first locking part 901. When the trigger mechanism is triggered, the locking block 7 enters the limiting groove 903, thereby limiting the angle of reverse rotation of the reverse drive shaft 8.

[0042] See Figures 1-10 The housing 1 includes a mounting base 102 and a mounting cover 101. The mounting cover 101 is mounted on the mounting base 102 by a bolt connection structure, and a positioning structure is provided between the mounting base 102 and the mounting cover 101. The positioning structure includes a positioning post and a positioning hole that mates with the positioning post. The positions of the positioning post and the positioning hole can be flexibly set according to actual conditions. For example, the positioning post can be set on the mounting base 102, and the positioning hole can be set on the mounting cover 101. By setting the above positioning structure, the convenience of assembly can be improved.

[0043] See Figures 1-10 The mounting cover 101 has a clearance groove at the connection between the drawer and the sliding buckle 2, and the clearance groove extends along the length of the housing 1. By providing the clearance groove, the drawer can be connected and separated from the hook groove 201 of the sliding buckle 2 through the connector, and the movement of the connector will not be interfered with.

[0044] Example 2

[0045] See Figure 11 The drawer of the present invention includes synchronous rebounders located on both sides of the drawer and a synchronizing element 12 for connecting the synchronous rebounders on both sides so that the synchronous rebounders on both sides are triggered synchronously. The synchronous rebounders are mounted on the furniture via mounting plates 10. The two sides of the synchronizing element 12 are respectively connected to the reverse drive shafts 8 in the synchronous rebounders on both sides via connecting components 11. With the above configuration, when the triggering mechanism in one of the synchronous rebounders is triggered, that is, when the reverse drive shaft 8 rotates, the synchronizing element 12 drives the reverse drive shaft 8 in the synchronous rebounder on the other side to rotate synchronously, thereby realizing that the synchronous rebounders on both sides are triggered at the same time. This ensures that the sliding latches 2 in the synchronous rebounders on both sides move synchronously in opposite directions, so that the rebound speed on both sides of the drawer is equal, ensuring that the drawer is not subjected to torsion or other forces, and allowing the drawer to open or close smoothly.

[0046] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
