Description

Technical Field

[0001] This invention relates to the field of press-and-return devices, and more specifically to a highly integrated drawer guide rail press-and-return device. Background Technology

[0002] Currently, drawers are connected to the cabinet via guide rails. Some high-end furniture also features a push-to-rebound mechanism. This mechanism requires force to overcome the spring's elasticity when closing the drawer, engaging the mechanism and locking the drawer in the closed position. To open the drawer, press it backward to release the mechanism, allowing the spring to push the drawer forward. Examples include Chinese invention patents CN214258594U ("A Rebound Damper for Three-Section Rails") and CN215820268U ("A Push-to-Rebound Drawer Device"). Existing technologies... The existing spring-loaded mechanism requires the drawer to be pushed to its final position and then released (the back of the drawer's front panel will contact the front of the cabinet) before it can lock. During the locking process, the spring deforms elastically, and its elastic potential energy gradually increases as the drawer moves further in the closing direction. Therefore, if the user accidentally does not push the drawer to its final position, or if a child pushes the drawer backward haphazardly, causing the spring-loaded mechanism to fail to lock, the drawer will spring back with considerable force, potentially hitting a person or other object and causing pain. As a result, the user experience of the existing spring-loaded mechanism is poor and needs to be improved. Summary of the Invention

Detailed Implementation

[0029] The present invention will now be further described with reference to the accompanying drawings.

[0030] The highly integrated drawer slide press-and-return device of the present invention, such as Figures 1 to 4 , Figure 11 and Figure 12 As shown (it should be noted that, Figure 1 An example is shown of the push-back mechanism on the right side of drawer 96, including a spring 9 for ejecting drawer 96 forward, a slide plate 2 for moving synchronously with drawer 96, and a connecting bar 3 that can be blocked by trigger 97; the connecting bar 3 and the slide plate 2 are slidably connected back and forth, specifically, as shown in... Figure 3 As shown, the connecting strip 3 is placed inside the slide plate 2, as... Figure 4 As shown, a spring housing is formed on the upper part of the connecting strip 3, such as... Figure 6 As shown, a first hook 2041 is formed in the upper part of the slide plate 2. The first hook 2041 hooks the upper edge of the spring housing of the connecting strip 3 to prevent the connecting strip 3 from detaching from the slide plate 2 in the left and right directions. In addition, the lower part of the connecting strip 3 is provided with a flat surface for abutting against the lower inner wall of the connecting slide plate 2, so that the connecting strip 3 can move back and forth relative to the slide plate 2. Figure 3 As shown, spring 9 is a tension spring. One end of spring 9 is connected to slide plate 2, and the other end of spring 9 is connected to connecting strip 3. Specifically, as shown... Figure 6 As shown, a first slot 205 is formed on the slide plate 2, such as Figure 4As shown, a second slot 35 is formed on the connecting strip 3, and the front and rear ends of the spring 9 are respectively engaged in the second slot 35 and the first slot 205. Figure 3 Spring 9 is in a state of elastic tension. For example... Figure 5 As shown, the connecting bar 3 is connected to a hook 32 that can clamp or release the trigger 97 by the relative back-and-forth movement of the slide plate 2 and the connecting bar 3. For example, such as Figure 5 As shown, a stop 31 is formed at the rear of the connecting strip 3. The stop 31 is used to block the contact of the trigger 97. The connecting strip 3 is hinged with a hook 32. Specifically, one end of the hook 32 is hinged to the connecting strip 3, and the corresponding other end of the hook 32 forms a sliding post 321, as shown. Figure 6 As shown, a hook guide groove 209 is formed on one side of the slide plate 2. The sliding column 321 is adapted to slide within the hook guide groove 209. The hook guide groove 209 includes a ramp guide groove. When the connecting bar 3 slides back and forth relative to the slide plate 2, the sliding column 321 can cause the hook 32 to swing relative to the connecting bar 3 during the process of sliding up or down the ramp guide groove. Figure 11 and Figure 12 As shown, the trigger 97 is fixed on the fixed rail 98 of the guide rail, and the movable rail 99 of the guide rail slides back and forth on the fixed rail 98. The drawer 96 is fixed relative to the movable rail 99, and the slide plate 2 is disposed on the movable rail 99. Thus, the slide plate 2 and the drawer 96 move back and forth synchronously. When the drawer 96 moves backward, the slide plate 2 and the connecting bar 3 move backward together. When the stop 31 of the connecting bar 3 contacts the trigger 97, the connecting bar 3 can no longer move backward, while the slide plate 2 continues to move backward. This causes the sliding column 321 to slide into the aforementioned inclined guide groove. Correspondingly, the clamp 32 swings downward to clamp the trigger 97 between the clamp 32 and the stop 31. In this way, the connecting bar 3 is temporarily fixed. Figure 6 and Figure 7 As shown, an upper unhooking slide 201 is formed on one side of the slide plate 2. The upper unhooking slide 201 includes a fork groove 2011, an inlet track 2012, and a retraction track 2013, as shown. Figure 5 As shown, the connecting strip 3 is hinged with a locking hook 4. One end of the locking hook 4 has a locking post 401 for sliding within the upper unlocking slide 201, and the corresponding other end of the locking hook 4 has a ring portion 402, as shown. Figure 5 As shown, the ring 402 is fitted onto the hinge pin 34 on one side of the connecting bar 3, allowing the locking hook 4 to swing, as... Figure 6 and Figure 7As shown, the front end of the inlet 2012 and the front end of the outlet 2013 are respectively connected to the fork groove 2011. The corresponding front side of the fork groove 2011 is formed with an unlocking guide block 208 for guiding the buckle 401 into the outlet 2013. The upper unlocking slide 201 includes an elastic clamp 2014 for elastically blocking the buckle 401 from rebounding backward relative to the slide plate 2. The elastic clamp 2014 is located behind the fork groove 2011. The entrance of the elastic clamp 2014 is connected to the inlet 2012, and the exit of the elastic clamp 2014 is connected to the outlet 2013. A retraction guide block 207 is formed on the inlet 2012 for guiding the buckle 401 to move to the corresponding position of the entrance of the elastic clamp 2014. The retraction guide block 207 is triangular in shape. The rear end of the upper unlocking slide 201 is formed with a starting position 2015. The rear end of the inlet 2012 and the rear end of the outlet 2013 converge and connect to the starting position 2015.

[0031] The sliding plate 2 has a first upper latch position relative to the connecting strip 3 and a second upper latch position corresponding to the closed state of the drawer 96. In the first upper latch position, the latch post 401 is located at the entrance of the elastic clamping channel 2014, such as... Figure 7 As shown, in the second upper buckle position, the buckle post 401 is located in the fork groove 2011.

[0032] like Figure 3 and Figure 12 As shown, the hook 32 has a working position for clamping the trigger 97 relative to the connecting bar 3. That is, in the above working position, the hook 32 holds the trigger 97. In the first upper latch position and the second upper latch position, the hook 32 remains in the working position. In other words, during the process of the slide plate 2 moving backward relative to the connecting bar 3, the hook 32 first swings downward to clamp the trigger 97, and then the latch 401 reaches the entrance position of the corresponding elastic channel 2014. Therefore, when the slide plate 2 is in the above first upper latch position or the above second upper latch position relative to the connecting bar 3, the hook 32 has already held the trigger 97.

[0033] The following is a brief explanation of the working principle of the press-and-return device of the present invention: When the user pushes the drawer 96 backward, the drawer 96 moves backward. Initially, the entire press-and-return device moves backward along with the drawer 96. However, when the drawer 96 is closed to a certain extent, the stop block 31 will collide with the trigger 97, so the connecting bar 3 can no longer move backward, while the slide plate 2 continues to move backward, causing the spring 9 to stretch and deform elastically. The slide column 321 moves forward relative to the hook guide groove 209. Then, the slide column 321 slides down the inclined guide groove of the hook guide groove 209, and the hook 32 is forced to swing downward to clamp the trigger 97 between the hook 32 and the stop block 31. Afterward, because the slide column 321 is guided horizontally forward by the hook guide groove 209, the hook 32 can then hold the trigger 97. At the same time, the latch 401 of the locking hook 4 also moves forward relative to the hook within the upper unlocking slide 201. Figure 7 As shown, specifically, the latch 401 moves forward relative to the guide rail 2012. After the latch 401 contacts the rear slope of the retraction guide block 207, it continues to move forward relative to the guide rail 207. When the front panel 961 of the drawer 96 contacts the front end of the cabinet, the drawer 96 can no longer move backward. The latch 401 is also guided to the corresponding position of the fork groove 2011 by the upper release slide 201. When the user releases the drawer, the elastic restoring force of the spring 9 pulls the slide plate 2 and the drawer 96 forward together, causing the latch 401 to move backward slightly relative to the guide rail 2011. The latch 401 then slides into the fork groove 2011, causing the press-back device to engage. At this time, the slide plate 2 is in the second engaged position relative to the connecting strip 3. Since the hook 32 still holds the trigger 97, the drawer 96 is locked in the closed position. When the user needs to open drawer 96, the user presses the front panel 961 of drawer 96 backward, causing the latch 401 to move forward slightly. The latch 401 contacts the release guide block 208. Guided by the release guide block 208, the latch 401 moves to the corresponding position of the retraction path 2013. The user releases drawer 96, and the slide plate 2 moves forward due to the elastic restoring force of spring 9. The latch 401 then enters the retraction path 2013. As drawer 96 and slide plate 2 move forward, when the slide 321 slides onto the ramp guide groove of the hook guide groove 209, the hook 32 is forced to swing upward to release the trigger 97, allowing drawer 96 to continue to be pulled forward by hand. The latch 401 also returns to the initial position 2015. When a user mistakenly prevents drawer 96 from moving backward sufficiently to engage the latch 401 with the fork groove 2011 (i.e., drawer 96 fails to close), or when a child pushes drawer 96 backward haphazardly, the latch 401, after passing the return guide block 207, rebounds backward relative to the slide plate 2 due to the elastic restoring force of the spring 9. When the latch 401 contacts the front inclined surface of the return guide block 207, as... Figure 7As indicated by the arrow, the retraction guide block 207 guides the latch 401 to the corresponding position at the entrance of the elastic channel 2014. Because the width of the elastic channel 2014 is smaller than the diameter of the latch 401, the latch 401 is elastically blocked by the elastic channel 2014 and cannot continue to move backward relative to the slide plate 2. At this time, the slide plate 2 is in the first upper latch position relative to the connecting strip 3, which prevents the drawer 96 from continuing to move forward and further prevents the drawer 96 from moving forward significantly due to inertia. This greatly reduces the possibility of the drawer 96 hitting a person or surrounding objects. Moreover, since the drawer 96 only has an initial forward velocity, even if it hits a person, it will not cause a significant impact (it will not cause pain). This improves the user experience of the press-and-return device of the present invention and makes the press-and-return device of the present invention more tolerant of errors. When the user needs to close the drawer 96 correctly, the user... Pushing the drawer 96 backward causes the latch 401 to move forward relative to the entrance of the elastic clamp 2014, and the latch 401 returns to the inlet 2012 and then moves to the fork slot 2011. When the latch 401 is in the first latched position, if the user pulls the drawer 96 forward, the latch 401 will push open the entrance of the elastic clamp 2014 and move backward relative to the slide plate 2, so that the latch 401 passes through the elastic clamp 2014 and returns to the retraction 2013 through the outlet of the elastic clamp 2014, thereby enabling the drawer 96 to open normally. Since the elastic clamp 2014 is elastically deformed and opened when the user pulls the latch 401 relative to it, the elastic clamp 2014 can be reset normally. In other words, since the blocking effect of the elastic clamp 2014 on the latch 401 is elastic (i.e., non-rigid), the elastic clamp 2014 is not damaged.

[0034] Furthermore, such as Figure 6 and Figure 7 As shown, the slide 2 has an elastic arm 206 and an island block 210 formed between the inlet 2012 and the outlet 2013. The rear end of the elastic arm 206 is suspended, meaning that the front end of the elastic arm 206 is integrated with the slide 2 body. The elastic channel 2014 is located between the elastic arm 206 and the island block 210. When the latch 401 enters the elastic channel 2014, the elastic arm 206 will be pushed and elastically bent by the latch 401. In some cases, if the latch 401 fails to close due to the user pushing the drawer 96 very forcefully and quickly, the drawer 96 will move forward quickly due to the rebound effect of the cabinet. The latch 401 may directly push open and pass through the elastic channel 2014. However, the elastic channel 2014 significantly hinders the relative backward movement of the latch 401, greatly reducing the kinetic energy of the drawer 96 rebounding forward due to the failure to close.

[0035] Furthermore, such as Figures 1 to 4As shown, the press-and-rebound device of the present invention also includes a housing 1 for fixing and connecting the movable rail 99, specifically, as Figure 2 As shown, a mounting hook 101, a rear positioning block 102, and a front positioning block 103 are formed on the outer wall of the outer casing 1. The mounting hook 101 hooks into a through groove on the movable rail 99. The rear positioning block 102 and the front positioning block 103 are respectively inserted into positioning holes on the movable rail 99. Thus, in the vertical direction, the rear positioning block 102 and the front positioning block 103 prevent the movable rail 99 from moving relative to the outer casing 1. In the front-back direction, the mounting hook 101 engages with the rear end of the rear positioning block 102 and the rear end of the front positioning block 103 to position the movable rail 99. Furthermore, the side of the outer casing 1 rests against one side of the movable rail 99, thus preventing the outer casing 1 from rotating relative to the movable rail 99. Figure 9 As shown, a mounting groove 100 is formed inside the outer casing 1, and the opening of the mounting groove 100 is oriented downwards, as... Figures 1 to 3 As shown, the slide plate 2 is fitted into the mounting groove 100, so that the slide plate 2 is restricted by the inner wall of the mounting groove 100 to move only in a straight line relative to the outer shell 1. More specifically, as shown... Figure 2 As shown, a snap hole 105 is formed on the side wall of the outer casing 1, as... Figure 6 As shown, a second hook 2042 is formed on the side of the skateboard 2, as... Figure 2 As shown, the second hook 2042 slides to engage with the corresponding buckle hole 105, preventing the slide plate 2 from detaching downwards from the outer casing 1. Figure 6 As shown, the front end of the slide plate 2 has a screw portion 202, as... Figure 3 As shown, the outer casing 1 is rotatably connected to a front and rear adjusting member 6, such as... Figure 10 As shown, a sleeve portion 601 is formed at the rear of the front and rear adjusting member 6, and an internal thread 6011 is formed inside the sleeve portion 601, as... Figure 3 As shown, the screw part 202 is connected to the internal thread 6011. Therefore, when the user rotates the front-to-back adjustment part 6 by hand, since the slide plate 2 cannot rotate relative to the outer shell 1, the front-to-back adjustment part 6 can drive the slide plate 2 to move back and forth relative to the outer shell 1 for adjustment. When the drawer 96 is in the closed state, since the slide plate 2 is already fixed relative to the connecting strip 3 (and the fixing rail 98), rotating the front-to-back adjustment part 6 can move the outer shell 1 and the drawer 96 back and forth together for adjustment, thereby adjusting the front and back position of the drawer 96 when it is in the closed state, so as to align the front panel 961 of the drawer 96 with the relevant structure of the furniture, and as... Figure 11 As shown, since guide rails and push-back mechanisms need to be installed on both the left and right sides of drawer 96, the front panel 961 can be adjusted to be balanced left and right by adjusting the front and rear adjustment parts 6 of the two push-back mechanisms respectively.

[0036] Furthermore, such as Figure 3 and Figure 4As shown, the press-and-rebound device of the present invention also includes a spring piece 7. One end of the spring piece 7 is connected to the outer shell 1, and the other end of the spring piece 7 is connected to the front and rear adjustment member 6. The front and rear adjustment member 6 and the outer shell 1 can move back and forth relative to each other, so that the spring piece 7 can bend and deform elastically. When the user closes the drawer 96 with great force and quickly, the drawer 96 bounces back after colliding with the cabinet. The latch 401 hooks the fork groove 2011, causing the slide plate 2 to lock. At this time, since the slide plate 2 has been positioned, the drawer 96 still has a large forward rebound kinetic energy due to the rebound effect of the cabinet. Therefore, the drawer 96 drives the outer shell 1 to push one end of the spring piece 7 forward, so that the spring piece 7 bends and deforms elastically to absorb the aforementioned forward rebound kinetic energy, thereby playing a buffering effect. This avoids damage to the locking hook 4, the fork groove 2011 and the front and rear adjustment member 6 and other related structures, which is conducive to the stable and durable function of the press-and-rebound device. It also avoids the phenomenon of the latch 401 hitting the fork groove 2011 and causing the latch 401 to fail to lock due to the strong rebound effect of the cabinet on the drawer 96.

[0037] Furthermore, such as Figure 9 As shown, a slot 104 is formed within the mounting groove 100, such as Figure 3 As shown, the upper end of the spring piece 7 is fitted into the slot 104, as... Figure 10 As shown, the front end of the front and rear adjusting member 6 has a handwheel 602 and a recessed neck 6021. The handwheel 602 protrudes downward from the outer casing 1, as shown. Figure 3 As shown, the lower end of the spring piece 7 is fitted into the recessed neck 6021. Specifically, the lower end of the spring piece 7 has a fork, which is fitted into the recessed neck 6021. The lower end of the spring piece 7 is against the inner wall of the recessed neck 6021, so the recessed neck 6021 can rotate within the fork. However, the recessed neck 6021 is axially positioned by the spring piece 7. Because the sleeve part 601 has been radially positioned by the screw part 202, but the parts are inevitably deformed and have inaccurate dimensions, by setting the above-mentioned locking structure, the spring piece 7 is prevented from repeatedly radially positioning the front and rear adjusting parts 6, the front and rear adjusting parts 6 are prevented from being subjected to excessive bending moment, and the front and rear adjusting parts 6 are also conducive to flexible rotation.

[0038] Furthermore, such as Figure 10 As shown, a notch 6012 is formed on the sleeve portion 601. The notch 6012 connects to the internal thread 6011. The notches 6012 are axially spaced and are staggered on both sides of the axis of the sleeve portion 601. By setting the notch 6012, the rigidity of the sleeve portion 601 is reduced, so that the sleeve portion 601 has a certain degree of flexibility and elasticity. This avoids the sleeve portion 601 and the screw portion 202 from being unable to be properly coaxial due to manufacturing and assembly errors, which would cause the screw portion 202 to break due to bending moment.

[0039] Furthermore, such as Figure 5 As shown, the front part of the connecting strip 3 has a rack portion 33, as... Figure 6 As shown, a rotating support hole 203 is formed on the slide plate 2, such as... Figure 3 As shown, a synchronous connector 5 is rotatably connected to the rotating support hole 203, such as... Figure 5 As shown, one end of the synchronizing connector 5 has a gear portion 51, and the corresponding other end of the synchronizing connector 5 has a rotating shaft portion 52, as shown. Figure 3 As shown, the gear section 51 and the rack section 33 are meshed and connected; as Figure 11 and Figure 12 As shown, the press-and-return device of the present invention also includes left and right synchronous connecting rods 8. The ends of the left and right synchronous connecting rods 8 are connected to the pivot parts 52. The left and right ends of the drawer bottom plate 962 of the drawer 96 are respectively connected to the corresponding movable rails 99. Accordingly, two sets of press-and-return devices of the present invention, which are symmetrical to each other, are respectively installed on the left and right movable rails 99. A left and right synchronous connecting rod 8 is set to connect the pivot parts 52 of the left and right sets of press-and-return devices. So when the slide plate 2 moves back and forth relative to the connecting strip 3, the left and right slide plates 2 can move synchronously through the transmission action of the left and right synchronous connecting rods 8, which is beneficial to make the drawer 96 close or pop out smoothly (especially when the user pushes the front panel 961 of the drawer 96 backward on one side).

[0040] Furthermore, such as Figure 12 As shown, the left and right synchronous connecting rods 8 have transmission grooves 801. These grooves 801 can be axially continuous (filling) the left and right synchronous connecting rods 8, allowing them to be manufactured using existing extrusion processes, which helps reduce costs. Figure 5 As shown, the rotating shaft 52 is a square shaft, and the rotating shaft 52 is adapted to be disposed within the transmission groove 801. In other words, the cross-section of the transmission groove 801 is rectangular, as shown in the figure. Figure 8 As shown, the slide plate 2 has a positioning groove 2031, such as Figure 12 As shown, the positioning groove 2031 is adapted to connect with one side outer wall of the left and right synchronous connecting rods 8. Specifically, the left and right synchronous connecting rods 8 are cylindrical in shape, so the positioning groove 2031 is a semi-circular groove, as shown. Figure 1 As shown, a cover 22 is installed on the skateboard 2, such as Figure 12As shown, the cover 22 is adapted to the outer wall of the corresponding side of the left and right synchronous connecting rods 8. The cover 22 can be opened to allow the left and right synchronous connecting rods 8 to disengage from the positioning groove 2031. Specifically, the positioning groove 2031 can support the left and right synchronous connecting rods 8 from below, making it convenient to put the ends of the left and right synchronous connecting rods 8 into the positioning groove 2031 when the cover 22 is opened, preventing the left and right synchronous connecting rods 8 from falling downwards. During the assembly process, the transmission groove 801 of the left and right synchronous connecting rods 8 is aligned downwards with the rotating shaft part 52, and then the transmission groove 801 is fitted onto the rotating shaft part 52. At this time, the left and right synchronous connecting rods 8 and the rotating shaft part 52 are coaxial. Then close the cover 22. The cover 22 and the positioning groove 2031 are combined to radially position the left and right synchronous connecting rods 8, and the slide plate 2 body is axially positioned for the left and right synchronous connecting rods 8. Since the rotating shaft 52 is a square shaft, the rotating shaft 52 and the left and right synchronous connecting rods 8 are circumferentially positioned, so that the left and right synchronous connecting rods 8 can work normally and stably. The rotating shaft 52 can drive the left and right synchronous connecting rods 8 to rotate synchronously. The above-mentioned installation structure of the rotating shaft 52 and the left and right synchronous connecting rods 8 makes it convenient and quick to install and remove the left and right synchronous connecting rods 8.

[0041] Furthermore, such as Figure 1 and Figure 12 As shown, one end of the cover 22 is hinged to the slide plate 2, and the corresponding other end of the cover 22 has a fastening groove 221. The fastening groove 221 can be a wall that penetrates the cover 22, such as... Figure 8 As shown, a protrusion 2032 is formed on the skateboard 2, such as Figure 1 and Figure 12 As shown, the buckle groove 221 and the protrusion buckle 2032 are adapted to fasten together. Therefore, when the buckle groove 221 and the protrusion buckle 2032 are unfastened, the cover 22 can swing open. After the cover 22 is opened, it is still connected to the slide plate 2 to prevent the cover 22 from falling off and being lost, and also to facilitate the cover 22 to close.

[0042] Furthermore, such as Figure 8 As shown, the slide plate 2 has a hinged protrusion 21, as... Figure 1 and Figure 12 As shown, the cover 22 is adapted to be mounted on the hinged protrusion 21, as follows: Figure 8As shown, the end of the hinge protrusion 21 has a flange 211 for preventing the cover 22 from axially disengaging from the hinge protrusion 21. An elastic groove 212 is formed on the hinge protrusion 21, which radially penetrates the flange 211. By setting the elastic groove 212, the end of the hinge protrusion 21 forms a fork-shaped structure. During the assembly of the cover 22, the hinge through hole on the cover 22 is fitted onto the end of the hinge protrusion 21, causing the fork-shaped structure to be elastically compressed. This allows the flange 211 to pass over the hinge through hole of the cover 22. Afterward, the fork-shaped structure elastically returns to its original position and opens, and the cover 22 is axially positioned on the hinge protrusion 21. This mounting structure avoids the need for screws, reduces the number of parts, and lowers costs.

[0043] In summary, the highly integrated drawer slide press-and-rebound device of the present invention integrates press-and-rebound, adjustable front and rear position, gear linkage, two-stage locking position, and energy absorption buffer function. The various functions are organically combined, which significantly improves the product's completeness and user experience.
