Technical Field
[0001] This invention belongs to the technical field of door and window hardware accessories, specifically relating to synchronous sliding mechanisms, furniture pocket doors, and wardrobes. Background Technology
[0002] Doors are an important component in modern architecture. With the advancement of people's aesthetic tastes and the development of technology, many doors that combine new technologies and designs have emerged, including pocket doors. Pocket doors are a type of sliding door with a concealed design that can be hidden in the building during application. They are not only aesthetically pleasing but also save space.
[0003] Currently, pocket doors require the assistance of sliding rails and rollers during application. For specific details, please refer to the concealed sliding rail for hinged doors disclosed in authorization announcement number CN209115002U. This concealed sliding rail for hinged doors has sliding door devices installed on the inner sides of the left and right sides of the cabinet, one above the other. The left and right ends of the sliding door devices are equipped with high and low guide rollers. The pull rod of the sliding door device is parallel to and opposite to the low guide roller at one end of the sliding door device. The pull rod and the terminal block between the upper and lower sliding door devices are then guided in an X-shape by the sliding line, so that the terminal block of the sliding door device can obtain a greater lateral sliding force on the sliding rail, thereby overcoming the friction force generated by the weight of the large cabinet door on the sliding rail. However, because the two sliding lines in the concealed sliding rail of the hinged door are X-shaped, the angle between the sliding lines winding in and out of the guide rollers will change with the size of the cabinet door. If the cabinet door is too large, the sliding lines will rub too much on the guide rollers, resulting in very unsmooth sliding. Therefore, this winding structure will limit the size of the cabinet. If the size is not within the design range, the sliding action will be unsmooth.
[0004] To address the aforementioned issues, the applicant's Chinese Patent Publication No. CN117072031B discloses a synchronous sliding mechanism and a furniture pocket door. The synchronous sliding mechanism includes: two guide rope wheel sets for installation within a cabinet and arranged vertically; two connecting members for installation on the cabinet door and arranged vertically; and a sliding rope member wound around the two guide rope wheel sets. The sliding rope member itself forms two parallel sliding rope segments that move synchronously in the same direction. The two connecting members are correspondingly arranged on the two parallel sliding rope segments. At least one of the parallel sliding rope segments is a portion of the sliding rope segment formed by the sliding rope member winding around one of the guide rope wheel sets once. The two guide rope wheel sets... The system comprises a first guide rope wheel group and a second guide rope wheel group. The second guide rope wheel group includes a first guide wheel and a fourth guide wheel arranged in the front-back direction. The first guide rope wheel group includes a second guide wheel and a third guide wheel arranged in the front-back direction. The two connecting components are a first connecting component and a second connecting component. The sliding rope component sequentially winds around the first guide wheel, the second guide wheel, the third guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel, forming a closed loop winding structure. The two unidirectional sliding rope segments are a first unidirectional sliding rope segment and a second unidirectional sliding rope segment. The second unidirectional sliding rope segment is the sliding rope segment between the first guide wheel and the fourth guide wheel and is connected to the second connecting component. The first unidirectional sliding rope segment is the sliding rope segment between the second guide wheel and the third guide wheel and is connected to the first connecting component.
[0005] However, the applicant discovered the following shortcomings in this synchronous sliding mechanism during actual production: 1. Because the sliding rope needs to be wound once between the second and third guide wheels before being wound again between the second and third guide wheels, in order to avoid the rope segments of the sliding rope from interfering with each other on the second and third guide wheels, the rope segments wound on the second and third guide wheels need to be staggered. This results in the rope segment of the sliding rope between the second and third guide wheels being slightly tilted with the sliding direction of the door, thus making the sliding of the door less smooth.
[0006] 2. The sliding rope needs to be wound between the first guide wheel and the second guide wheel. The first guide wheel and the second guide wheel are located at the front of the cabinet. The rope segment between the first guide wheel and the second guide wheel occupies the space at the front of the cabinet, which makes the functional expandability of this area poor and makes it difficult to meet the user's needs for diversified furniture functions. Summary of the Invention
[0007] In order to overcome at least one of the defects mentioned above in the prior art, the present invention provides a synchronous sliding mechanism, a furniture pocket door, and a wardrobe to solve the problems of insufficient smooth sliding of pocket doors and poor functional expandability of the front space of the cabinet in the prior art, so as to achieve the effect of smoother door sliding and more space in the front of the cabinet for expanding other functional components.
[0008] The technical solution adopted by this invention to solve its problem is: A synchronous sliding mechanism includes: a guide wheel assembly comprising a first guide wheel, a second guide wheel, a third guide wheel, and a fourth guide wheel for fixing to a cabinet, wherein the first guide wheel and the fourth guide wheel are front-to-back facing each other, and the second guide wheel and the third guide wheel are front-to-back facing each other, with the first guide wheel located below the second guide wheel; a pulley assembly comprising a first pulley and a second pulley positioned vertically opposite each other, wherein the first pulley is located below the second pulley, and the fourth guide wheel is located below the third guide wheel, both the first pulley and the second pulley being used to slide along a track provided on the cabinet; a first sliding rope, wherein a first end of the first sliding rope is connected to the first pulley, and a second end of the first sliding rope is sequentially wound around the fourth guide wheel, the third guide wheel, and the second guide wheel before being connected to the second pulley; the rope segment of the first sliding rope connecting the first pulley and the fourth guide wheel is the first sliding rope segment, and the rope segment of the first sliding rope connecting the second pulley and the second guide wheel is the second sliding rope segment. The first sliding rope is connected between the second guide wheel and the third guide wheel as the third sliding rope segment. The second sliding rope segment and the first sliding rope segment move synchronously and in the same direction through the transmission of the third sliding rope segment. The second sliding rope has its first end connected to the second pulley, and its second end sequentially wound around the third guide wheel, the fourth guide wheel, and the first guide wheel before being connected to the first pulley. The second sliding rope is connected between the second pulley and the third guide wheel as the fourth sliding rope segment. The second sliding rope is connected between the first pulley and the first guide wheel as the fifth sliding rope segment. The second sliding rope segment and the fifth sliding rope segment move synchronously and in the same direction through the transmission of the sixth sliding rope segment. The movement direction of the second sliding rope segment is parallel to the track of the cabinet.
[0009] As an optional implementation, the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel are all provided with a first rope groove and a second rope groove. The projections of all the first rope grooves onto the ground are on the same straight line, and the projections of all the second rope grooves onto the ground are on the same straight line. The second end of the first sliding rope is sequentially wound around the first rope grooves of the fourth guide wheel, the third guide wheel, and the second guide wheel, and then connected to the second pulley. The second end of the second sliding rope is sequentially wound around the second rope grooves of the third guide wheel, the fourth guide wheel, and the first guide wheel, and then connected to the first pulley.
[0010] As an optional implementation, the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel are each composed of a single wheel body; or, the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel are each composed of two coaxial wheel bodies with the same diameter, wherein the first rope groove and the second rope groove of the first guide wheel are located on the two wheel bodies respectively, the first rope groove and the second rope groove of the second guide wheel are located on the two wheel bodies respectively, the first rope groove and the second rope groove of the third guide wheel are located on the two wheel bodies respectively, and the first rope groove and the second rope groove of the fourth guide wheel are located on the two wheel bodies respectively.
[0011] As an optional implementation, the first pulley is provided with a first tensioning structure, and the first end of the first sliding rope is connected to the first tensioning structure, the first tensioning structure being used to adjust the tension of the first sliding rope; and / or, the second pulley is provided with a second tensioning structure, and the first end of the second sliding rope is connected to the second tensioning structure, the second tensioning structure being used to adjust the tension of the second sliding rope.
[0012] As an optional implementation, the first pulley is provided with a first tensioning structure, which includes a first connecting block and a first screw. The first pulley has a first wheel seat, the first screw is rotatably disposed on the first wheel seat, the first connecting block is slidably disposed on the first wheel seat, the first connecting block and the first screw are threadedly connected, and the first end of the first sliding rope is fixedly connected to the first connecting block. Rotating the first screw can drive the first connecting block to slide relative to the first wheel seat in the front-back direction.
[0013] As an optional implementation, the first wheel seat is provided with a first groove, and the first connecting block is slidably disposed in the first groove.
[0014] As an optional implementation, the first guide wheel and the second guide wheel are positioned vertically opposite each other, and the third guide wheel and the fourth guide wheel are positioned vertically opposite each other.
[0015] As an optional implementation, the vertical sections of the first and second sliding ropes are parallel to each other and both perpendicular to the ground.
[0016] As an optional implementation, the positions of the first guide wheel, the second guide wheel, the third guide wheel, and the fourth guide wheel are adjustable relative to the cabinet in the front-to-back direction.
[0017] In addition, the present invention also provides a furniture pocket door, including a synchronous sliding mechanism as described in any of the above embodiments, and further including a door body, a connecting plate and a hinge, wherein the connecting plate is connected between the first pulley and the second pulley, and the door body is connected to the connecting plate via the hinge.
[0018] In addition, the present invention also provides a wardrobe, including a furniture pocket door as described in the above embodiment, and a cabinet body, wherein the first guide wheel, the second guide wheel, the third guide wheel and the fourth guide wheel are fixed to the cabinet body, and the first pulley and the second pulley are slidably disposed on the track of the cabinet body.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: Both a first sliding rope and a second sliding rope were used, and the winding method was improved. The first end of the first sliding rope was directly connected to the first pulley and did not need to be wound around the first guide wheel. The first end of the second sliding rope was directly connected to the second pulley and did not need to be wound around the second guide wheel.
[0020] In this way, firstly, the first, second, third, fourth, fifth, and sixth sliding rope segments are always parallel to the cabinet's track, eliminating the problem of rope segment tilting relative to the door's sliding direction. This significantly reduces friction and resistance during sliding, resulting in smoother door sliding and improved user experience. Secondly, since both the first and second pulleys slide synchronously with the door, when the door is pushed, the force on the second pulley first pulls the second sliding rope segment, then quickly transmits it through the third sliding rope segment to the first sliding rope segment, thus pulling the first pulley. The force on the first pulley then pulls the fifth sliding rope segment, and then promptly transmits it through the sixth sliding rope segment to the fourth sliding rope segment, thus pulling the second pulley. This force transmission mechanism creates a synergistic effect between the two pulleys, automatically tending towards balance even if the direction of the pushing force on the door deviates, effectively ensuring the synchronous sliding of the first and second pulleys, further improving the stability and reliability of the door's sliding. Thirdly, the elimination of the need for ropes between the first and second guide wheels allows the front of the cabinet to be freed from the space occupied by the sliding ropes, thus providing more usable space in the front of the cabinet to expand other functional components.

[0035] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.
[0036] Please see Figures 1 to 7 This application provides a synchronous sliding mechanism, including a guide wheel assembly 1, a pulley assembly 2, a first sliding rope 3, and a second sliding rope 4. The guide wheel assembly 1 includes a first guide wheel 11, a second guide wheel 12, a third guide wheel 13, and a fourth guide wheel 14 for fixing to a cabinet 8. The first guide wheel 11 and the fourth guide wheel 14 are opposite each other, and the second guide wheel 12 and the third guide wheel 13 are opposite each other. The first guide wheel 11 is located below the second guide wheel 12, and the fourth guide wheel 14 is located below the third guide wheel 13. The pulley assembly 2 includes a first pulley 21 and a second pulley 22 that are opposite each other. The first pulley 21 is located below the second pulley 22. Both the first pulley 21 and the second pulley 22 are used to slide on a track 83 provided on the cabinet 8. like Figure 2 , Figure 3 ,and Figure 5As shown, the first end of the first sliding rope 3 is connected to the first pulley 21, and the second end of the first sliding rope 3 is sequentially wound around the fourth guide wheel 14, the third guide wheel 13, and the second guide wheel 12 before being connected to the second pulley 22. The rope segment of the first sliding rope 3 connected between the first pulley 21 and the fourth guide wheel 14 is the first sliding rope segment 31, the rope segment of the first sliding rope 3 connected between the second pulley 22 and the second guide wheel 12 is the second sliding rope segment 32, and the rope segment of the first sliding rope 3 connected between the second guide wheel 12 and the third guide wheel 13 is the third sliding rope segment 33. The second sliding rope segment 32 and the first sliding rope segment 31 move synchronously and in the same direction through the transmission of the third sliding rope segment 33. like Figure 2 , Figure 4 and Figure 6 As shown, the first end of the second sliding rope 4 is connected to the second pulley 22, and the second end of the second sliding rope 4 is sequentially wound around the third guide wheel 13, the fourth guide wheel 14 and the first guide wheel 11 before being connected to the first pulley 21; the rope segment of the second sliding rope 4 connected between the second pulley 22 and the third guide wheel 13 is the fourth sliding rope segment 41, the rope segment of the second sliding rope 4 connected between the first pulley 21 and the first guide wheel 11 is the fifth sliding rope segment 42, and the rope segment of the second sliding rope 4 connected between the first guide wheel 11 and the fourth guide wheel 14 is the sixth sliding rope segment 43. The fifth sliding rope segment 42 and the fourth sliding rope segment 41 move synchronously and in the same direction through the transmission of the sixth sliding rope segment 43; the second sliding rope segment 32 and the fifth sliding rope segment 42 move synchronously and in the same direction; the direction of movement of the second sliding rope segment 32 is parallel to the track of the cabinet 8.
[0037] It should be noted that, as Figure 3 and Figure 5 As shown, the third sliding rope segment 33 is not directly connected to the second pulley 22; the third sliding rope segment 33 is indirectly connected to the second pulley 22 through the second sliding rope segment 32. Figure 4 and Figure 6 As shown, the sixth sliding rope segment 43 is not directly connected to the first pulley 21; the sixth sliding rope segment 43 is indirectly connected to the first pulley 21 through the fifth sliding rope segment 42. The synchronous sliding mechanism provided in this application embodiment uses both a first sliding rope 3 and a second sliding rope 4, and improves the winding method. The first end of the first sliding rope 3 is directly connected to the first pulley 21 and does not need to be wound around the first guide wheel 11. The first end of the second sliding rope 4 is directly connected to the second pulley 22 and does not need to be wound around the second guide wheel 12. Thus, firstly, the first sliding rope segment 31, the second sliding rope segment 32, the third sliding rope segment 33, the fourth sliding rope segment 41, the fifth sliding rope segment 42, and the sixth sliding rope segment 43 are always parallel to the track of the cabinet 8, eliminating the problem of rope segment tilting relative to the sliding direction of the door 5, greatly reducing friction and resistance during the sliding process, thereby making the sliding of the door 5 smoother and improving the user experience. Secondly, since both the first pulley 21 and the second pulley 22 slide synchronously with the door 5, when the pulley group 2 is in the initial position and the door 5 is pushed (see reference...), Figure 3 and Figure 4 The force on the second pulley 22 first pulls the second sliding rope segment 32, and then quickly transmits it through the third sliding rope segment 33 to the first sliding rope segment 31, thereby pulling the first pulley 21. The force on the first pulley 21 then pulls the fifth sliding rope segment 42, and then timely transmits it through the sixth sliding rope segment 43 to the fourth sliding rope segment 41, thereby pulling the second pulley 22. This force transmission mechanism enables the two pulleys to work together, and even if there is a deviation in the direction of the pushing force on the door 5, it can automatically tend to balance, effectively ensuring the synchronous sliding of the first pulley 21 and the second pulley 22, and further improving the stability and reliability of the sliding of the door 5. Thirdly, there is no need to wrap the rope between the first guide wheel 11 and the second guide wheel 12. This improvement means that the front of the cabinet 8 is no longer occupied by the sliding rope, thus providing more usable space in the front of the cabinet 8 to expand other functional components.
[0038] More specifically, when pulley block 2 is at its end position and door 5 is pulled (see reference) Figure 5 and Figure 6 The force on the second pulley 22 will first pull the fourth sliding rope segment 41, and then quickly transmit it to the fifth sliding rope segment 42 through the sixth sliding rope segment 43, thereby pulling the first pulley 21. The force on the first pulley 21 will then pull the first sliding rope segment 31, and then timely transmit it to the second sliding rope segment 32 through the third sliding rope segment 33, thereby pulling the second pulley 22. This force transmission mechanism enables the two pulleys to work together.
[0039] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, more specifically, in this embodiment, the first sliding rope 3 is connected between the third guide wheel 13 and the fourth guide wheel 14 by the rope segment of the first sliding rope 3, which is the seventh sliding rope segment 34. The first sliding rope segment 31, the seventh sliding rope segment 34, the third sliding rope segment 33, and the second sliding rope segment 32 are connected in sequence. The second sliding rope 4 is connected between the third guide wheel 13 and the fourth guide wheel 14 by the rope segment of the second sliding rope 4, which is the eighth sliding rope segment 44. The fourth sliding rope segment 41, the eighth sliding rope segment 44, the sixth sliding rope segment 43, and the fifth sliding rope segment 42 are connected in sequence. The seventh sliding rope segment 34 and the eighth sliding rope segment 44 are parallel to each other.
[0040] like Figure 2 As shown, in one embodiment, the first guide wheel 11, the second guide wheel 12, the third guide wheel 13, and the fourth guide wheel 14 are all provided with a first rope groove 15 and a second rope groove 16. The projections of all the first rope grooves 15 onto the ground are on the same straight line, and the projections of all the second rope grooves 16 onto the ground are on the same straight line. The second end of the first sliding rope 3 is sequentially wound around the first rope grooves 15 of the fourth guide wheel 14, the third guide wheel 13, and the second guide wheel 12, and then connected to the second pulley 22. The second end of the second sliding rope 4 is sequentially wound around the second rope grooves 16 of the third guide wheel 13, the fourth guide wheel 14, and the first guide wheel 11, and then connected to the first pulley 21. In this way, each first sliding rope 3 and second sliding rope 4 has an independent and clear running path, avoiding the first sliding rope 3 and the second sliding rope 4 from tangling and rubbing against each other during operation due to path intersection or overlap.
[0041] like Figure 2 As shown, in one embodiment, the first guide wheel 11, the second guide wheel 12, the third guide wheel 13 and the fourth guide wheel 14 are each composed of a wheel body.
[0042] It should be noted that in some other embodiments, the first guide wheel 11, the second guide wheel 12, the third guide wheel 13, and the fourth guide wheel 14 are each composed of two coaxial wheel bodies with the same diameter. The first rope groove 15 and the second rope groove 16 of the first guide wheel 11 are located on the two wheel bodies respectively. The first rope groove 15 and the second rope groove 16 of the second guide wheel 12 are located on the two wheel bodies respectively. The first rope groove 15 and the second rope groove 16 of the third guide wheel 13 are located on the two wheel bodies respectively. The first rope groove 15 and the second rope groove 16 of the fourth guide wheel 14 are located on the two wheel bodies respectively.
[0043] like Figure 7 As shown, in one embodiment, the first pulley 21 is provided with a first tensioning structure 212, and the first end of the first sliding rope 3 is connected to the first tensioning structure 212. The first tensioning structure 212 is used to adjust the tension of the first sliding rope 3. In this way, the operator can precisely adjust the tension of the first sliding rope 3 according to actual needs. Whether it is due to the loosening of the sliding rope after long-term use or the need for a specific tension during initial installation, it can be easily achieved through the tensioning structure, ensuring that the first sliding rope 3 is always in the best working condition.
[0044] like Figure 7 As shown, in one embodiment, the first pulley 21 is provided with a first tensioning structure 212, which includes a first connecting block 2121 and a first screw 2122. The first pulley 21 has a first wheel seat 211, the first screw 2122 is rotatably disposed on the first wheel seat 211, and the first connecting block 2121 is slidably disposed on the first wheel seat 211. The first connecting block 2121 and the first screw 2122 are threadedly connected, and the first end of the first sliding rope 3 is fixedly connected to the first connecting block 2121. Rotating the first screw 2122 can drive the first connecting block 2121 to slide relative to the first wheel seat 211 in the front-back direction. Thus, in a first aspect, this threaded connection method has self-locking properties, which can automatically lock the position of the first connecting block 2121 after it moves to a suitable position, preventing loosening due to vibration or other external forces during equipment operation, and ensuring the stability and reliability of the first tensioning structure 212. Secondly, by rotating the first screw 2122 to drive the first connecting block 2121 to slide relative to the first wheel seat 211 in the front-back direction, the operator can precisely control the moving distance of the first connecting block 2121 according to actual needs, thereby achieving fine adjustment of the tension of the first sliding rope 3. Whether it is a slight tension adjustment or a larger relaxation adjustment, it can be easily achieved, meeting the requirements of the tension of the first sliding rope 3 under different working conditions.
[0045] like Figure 7 As shown, in one embodiment, the first wheel seat 211 is provided with a first sliding groove 2111, and the first connecting block 2121 is slidably disposed in the first sliding groove 2111. This ensures that the first connecting block 2121, driven by the first screw 2122, can only move linearly along the direction (front-back direction) set by the first sliding groove 2111, avoiding deviation, shaking, or jamming during sliding, thus ensuring the stability and accuracy of the sliding and laying the foundation for subsequent precise adjustment of the tension of the first sliding rope 3. Furthermore, by setting the first sliding groove 2111 on the first wheel seat 211, the space of the first wheel seat 211 is fully utilized without adding excessive structural components, making the entire first tensioning structure 212 more compact. This compact structural design not only saves installation space but also reduces mutual interference between components, improving the overall reliability and stability of the device.
[0046] In one embodiment, the second pulley 22 is provided with a second tensioning structure (not shown in the figure), and the first end of the second sliding rope 4 is connected to the second tensioning structure, which is used to adjust the tension of the second sliding rope 4. This allows the operator to precisely adjust the tension of the second sliding rope 4 according to actual needs. Whether it's due to slackness after long-term use or the need for specific tension during initial installation, this tensioning structure can easily achieve the desired result, ensuring that the second sliding rope 4 is always in optimal working condition.
[0047] In one embodiment, the second tensioning structure is substantially the same as the first tensioning structure 212.
[0048] It should be noted that the first and second tensioning structures mentioned above can be set together or set separately, depending on the actual needs.
[0049] It should be noted that in some other embodiments, the first tensioning structure 212 and the second tensioning structure may be, but are not limited to, a gear and rack structure or a telescopic rod structure, whichever is selected according to actual needs.
[0050] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the first guide wheel 11 and the second guide wheel 12 are positioned vertically opposite each other, and the third guide wheel 13 and the fourth guide wheel 14 are also positioned vertically opposite each other. This arrangement ensures that the closed line connecting the first guide wheel 11, the second guide wheel 12, the third guide wheel 13, the fourth guide wheel 14, and the first guide wheel 11 forms a rectangle. This avoids the formation of sharp angles between the first sliding rope 3 and the second sliding rope 4 during winding, resulting in smoother and more fluid sliding.
[0051] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the vertical segments of the first sliding rope 3 and the second sliding rope 4 are parallel to each other and both perpendicular to the ground. This reduces the additional friction caused by tilting or bending, resulting in less resistance during the sliding of the cabinet door, making the sliding smoother and more fluid, and effectively improving the user experience when using the pocket door. Specifically, the vertical segment of the first sliding rope 3 refers to the seventh sliding rope segment 34, and the vertical segment of the second sliding rope 4 refers to the eighth sliding rope segment 44.
[0052] Admittedly, in some other embodiments, the first guide wheel 11 and the second guide wheel 12 may also be staggered in the vertical direction, and the third guide wheel 13 and the fourth guide wheel 14 may also be staggered in the vertical direction. In this way, the closed line connecting the first guide wheel 11, the second guide wheel 12, the third guide wheel 13, the fourth guide wheel 14 and the first guide wheel 11 will form a parallelogram or a trapezoid. The choice can be made according to the actual needs, and no unique limitation is made here.
[0053] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the positions of the first guide wheel 11, the second guide wheel 12, the third guide wheel 13, and the fourth guide wheel 14 are adjustable relative to the cabinet 8 in the front-to-back direction, thereby adjusting the tension of the first sliding rope 3 and the second sliding rope 4. Firstly, in actual installation, factors such as manufacturing errors in the cabinet 8 and uneven installation surfaces may lead to an unsatisfactory initial sliding rope state. The adjustable guide wheel position design allows for fine-tuning for different installation environments. By flexibly adjusting the guide wheel position to control the sliding rope tension, it ensures that the sliding rope is always at a suitable tension. When the sliding rope is too loose, the cabinet door may wobble or jam; when it is too tight, it will increase sliding resistance. This design effectively avoids these problems, allowing the cabinet door to slide smoothly and steadily, improving the user experience. Secondly, after long-term use, the sliding rope may loosen due to wear and aging. In this case, no complicated operation is required; simply adjusting the guide wheel position is sufficient to re-tension the sliding rope, reducing maintenance difficulty and cost, and extending the service life of the entire synchronous sliding mechanism and the pocket door.
[0054] like Figure 2 As shown, in one embodiment, the first guide wheel 11, the second guide wheel 12, the third guide wheel 13, and the fourth guide wheel 14 have the same radius. This identical guide wheel radius ensures that the sliding rope's trajectory and speed characteristics are consistent across all guide wheels. During the sliding of the cabinet door, the first sliding rope 3 and the second sliding rope 4 can transmit power in a more coordinated manner, keeping the sliding speed and displacement of the first pulley 21 and the second pulley 22 highly synchronized. This ensures smooth and stable opening and closing of the cabinet door, avoiding problems such as jamming and shaking caused by asynchronous sliding, and improving the user experience of using the pocket door.
[0055] like Figure 1 As shown, this embodiment also provides a furniture pocket door, including the synchronous sliding mechanism described in any of the above embodiments, and further including a door body 5, a connecting plate 6, and a hinge 7. The connecting plate 6 is connected between the first pulley 21 and the second pulley 22, and the door body 5 is connected to the connecting plate 6 via the hinge 7. When the door body 5 rotates relative to the cabinet 8 to the open position, the pulley assembly 2 is in the following position: Figure 3 and Figure 4As shown in the initial position, then guided by the synchronous sliding mechanism, the door 5 can slide to one side of the cabinet 8 to achieve concealment, at which point the pulley block 2 is in position. Figure 5 and Figure 6 The endpoint position is shown.
[0056] like Figure 1 As shown, this embodiment also provides a wardrobe, including the furniture pocket door as described above, and a cabinet body 8. The upper and lower parts of the cabinet body 8 are respectively provided with tracks 83. The first guide wheel 11, the second guide wheel 12, the third guide wheel 13 and the fourth guide wheel 14 are fixed to the cabinet body 8. The first pulley 21 slides on the track 83 at the lower part of the cabinet body 8, and the second pulley 22 slides on the track 83 at the upper part of the cabinet body 8.
[0057] like Figure 1 and Figure 2 As shown, in one embodiment, the cabinet 8 is provided with a parallel first mounting groove 81 and a second mounting groove 82, both extending in the front-to-back direction. The first mounting groove 81 and the second mounting groove 82 are vertically opposite each other, with the first mounting groove 81 located below the second mounting groove 82. A first guide wheel 11 and a fourth guide wheel 14 are connected to the first mounting groove 81, and a second guide wheel 12 and a third guide wheel 13 are connected to the second mounting groove 82. When the position of the guide wheels needs to be adjusted, the first guide wheel 11 and the fourth guide wheel 14 can be moved relative to the first mounting groove 81, and the second guide wheel 12 and the third guide wheel 13 can be moved relative to the second mounting groove 82. Since the first guide wheel 11 and the fourth guide wheel 14 can move in the first mounting groove 81, and the second guide wheel 12 and the third guide wheel 13 can move in the second mounting groove 82, when the first sliding rope 3 and the second sliding rope 4 become slack or too tight, the winding length of the sliding rope can be changed by precisely moving the guide wheel positions. This allows for fine adjustment of the sliding rope tension, ensuring that the sliding rope is always in the optimal tension state and guaranteeing smooth and unobstructed sliding of the cabinet door. Furthermore, during installation, the guide wheel positions can be roughly fixed first, and then fine-tuned according to the actual sliding effect, reducing installation difficulty and precision requirements, and improving installation efficiency. In later use, if the sliding rope needs to be readjusted due to wear or other reasons, it can be done simply by moving the guide wheel, without disassembling the entire mechanism, making maintenance more convenient and efficient.
[0058] like Figure 1 and Figure 2 As shown, in one embodiment, the first guide wheel 11 includes a base 111 and a guide wheel body 112. The guide wheel body 112 is rotatably mounted on the base 111. The second sliding rope 4 is wound around the guide wheel body 112. The base 111 is provided with a plug-in block 113, which is inserted into the first mounting groove 81. After the position of the base 111 is adjusted, the base 111 and the first mounting groove 81 can be fixed by fasteners.
[0059] It should be noted that in this embodiment, the assembly structure of the second guide wheel 12, the third guide wheel 13, and the fourth guide wheel 14 in the cabinet 8 is basically the same as the assembly structure of the first guide wheel 11 in the cabinet 8, and will not be described again here. Of course, in some other embodiments, the assembly structure of the second guide wheel 12, the third guide wheel 13, and the fourth guide wheel 14 in the cabinet 8 may also be different from the assembly structure of the first guide wheel 11 in the cabinet 8, and can be selected according to actual needs.
[0060] Specifically, in this embodiment, the up and down direction can be referred to as Figure 3 and Figure 5 The direction of e1 in the figure, the forward and backward directions can be referenced. Figure 3 and Figure 5 In the e2 direction.
[0061] In summary, the synchronous sliding mechanism, furniture pocket door, and wardrobe disclosed in this invention can bring at least the following beneficial technical effects: (1) The first sliding rope segment 31, the second sliding rope segment 32, the third sliding rope segment 33, the fourth sliding rope segment 41, the fifth sliding rope segment 42 and the sixth sliding rope segment 43 are always parallel to the track of the cabinet 8, eliminating the problem of the rope segment tilting in the sliding direction of the door 5, greatly reducing the friction and resistance during the sliding process, thus making the sliding of the door 5 smoother and improving the user experience.
[0062] (2) Since the first pulley 21 and the second pulley 22 slide synchronously with the door body 5, when the upper part of the door body 5 is pushed, the force on the second pulley 22 will be quickly transmitted to the first pulley 21 through the second sliding rope 4, and the force on the first pulley 21 will be transmitted to the second pulley 22 in time through the first sliding rope 3. This force transmission mechanism enables the two pulleys to form a synergistic effect. Even if there is a deviation in the direction of the pushing force on the door body 5, it can automatically tend to balance, effectively ensuring the synchronous sliding of the first pulley 21 and the second pulley 22.
[0063] (3) No rope needs to be wound between the first guide wheel 11 and the second guide wheel 12. This improvement means that the front of the cabinet 8 is no longer occupied by the sliding rope, thus providing more usable space for the front of the cabinet 8 to expand other functional components.
[0064] (4) The design of the first rope groove 15 and the second rope groove 16 ensures that each first sliding rope 3 and the second sliding rope 4 has an independent and clear running route, avoiding the first sliding rope 3 and the second sliding rope 4 from getting tangled and rubbing against each other during operation due to path intersection or overlap.
[0065] (5) The first tensioning structure 212 is used to adjust the tension of the first slide rope 3. This allows the operator to precisely adjust the tension of the first slide rope 3 according to actual needs. Whether it is due to the loosening of the slide rope after long-term use or the need for specific tension during initial installation, it can be easily achieved through this tensioning structure, ensuring that the first slide rope 3 is always in the best working condition.
[0066] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
