Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of furniture, and in particular, to a synchronous sliding mechanism and a furniture pocket door.BACKGROUND

[0002] In modern architecture, doors are an important component. With the advancement of aesthetic preferences and technological development, many doors incorporating new technologies and designs have emerged, including pocket doors. A pocket door is a type of sliding door employing a hidden design, which may be concealed within the structure during application, offering not only an aesthetically pleasing and elegant design but also space-saving benefits.

[0003] In current applications, pocket doors require the coordinated assistance of slide rails and rollers. For specific reference, one may consider the concealed sliding track for a flat-opening door disclosed in the utility model with grant publication no. CN209115002U. This concealed sliding track for a flat-opening door is installed on the inner left and right side surfaces inside a cabinet body, with upper and lower sliding door devices respectively. The left and right ends of the sliding door device are equipped with an upper and a lower guide pulley arranged at different heights. The pull rope rod of the sliding door device is positioned parallel and opposite to the lower guide pulley at one end of the sliding door device. Then, a sliding rope is used to form an X-shaped guide between the pull rope rod and the connection post of the upper and lower sliding door devices, enabling the connection plate of the sliding door device to obtain greater lateral sliding force in the slide rail, thereby overcoming the friction force generated by the gravity of a large cabinet door on the slide rail.

[0004] However, as the two sliding ropes in this concealed sliding track for a flat-opening door are arranged in an X-shape, the angle at which the sliding ropes wind into and out of the guide pulleys varies with the size of the cabinet door. If the cabinet door size is too large, excessive friction of the sliding ropes on the guide pulleys may lead to very unsmooth sliding. Therefore, this winding structure limits the size of the cabinet body. When the size is outside the designed adaptation range, the sliding action becomes unsmooth, leaving room for improvement.SUMMARY

It is only intended to facilitate description of the present disclosure and simplify description, but not to indicate or imply that the referred device or element has a specific orientation, or is constructed and operated in a specific orientation. Therefore, they should not be construed as a limitation of the present disclosure.

[0022] Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are used only to describe specific embodiments and are not intended as a limitation of the disclosure.

[0023] With reference to FIGS. 1-12, an embodiment of the present invention discloses a synchronous sliding mechanism and a furniture pocket door equipped with the synchronous sliding mechanism. The synchronous sliding mechanism is assembled between an accommodating groove 11 of a cabinet body 1 and a cabinet door 2 of the furniture pocket door, and is configured to retract the cabinet door 2 into the cabinet body 1. In the illustrated embodiment, the cabinet body 1 is provided with accommodating grooves 11 on both sides along a length direction thereof, that is, the cabinet body 1 is provided with accommodating grooves 11 on both left and right sides, and two cabinet doors 2 are correspondingly provided. The two cabinet doors 2 are respectively retracted into the two accommodating grooves 11. In the illustrated embodiment, the left-right direction refers to the length direction of the cabinet body 1 in the figures.Embodiment 1 Structure of the Synchronous Sliding Mechanism

[0024] With reference to FIGS. 1-12, the synchronous sliding mechanism includes: two guide pulley assemblies configured to be arranged in the cabinet body 1 and extending in an up-down direction; in the illustrated embodiment, the up-down direction refers to the height direction of the cabinet body 1. two connection members configured to be arranged on the cabinet door 2 and extending in the up-down direction; a sliding rope member 3, where the sliding rope member 3 is wound around the two guide pulley assemblies, the sliding rope member 3 itself forms two synchronous rope segments that are arranged parallel to each other in the up-down direction and move synchronously in the same direction, and the two connection members are respectively arranged on the two synchronous rope segments; at least one of the two synchronous rope segments of the sliding rope member 3 is at least a part of a rope segment formed by the sliding rope member 3 being wound around one of the guide pulley assemblies for one circle.

[0025] In view of the issues in the prior art that the winding structure may cause the sliding action of the cabinet door 2 become unsmooth when the size of the cabinet body 1 is outside the designed adaptation range, the synchronous sliding mechanism of the present embodiment improves the structure of the sliding rope member 3, enabling adaptation to cabinet bodies 1 of various sizes, ensuring smooth sliding of the cabinet door 2, and improving sliding smoothness. The specific working principle is as follows: The sliding rope member 3 itself forms two synchronous rope segments arranged up and down, driving the two connection members to move synchronously in the same direction, ensuring smooth movement of the cabinet door 2; moreover, one of the synchronous rope segments of the sliding rope member 3 is formed by winding around one guide pulley assembly for one circle, causing that synchronous rope segment to wind around the guide pulley at a circumferential angle of approximately 180°. Thus, the sliding rope member 3 as a whole may form a substantially square winding structure, which is different from the X-shaped winding in the prior art. The angle at which the sliding rope member 3 winds into and out of the guide pulleys 4 does not change with the size of the cabinet body 1, thereby enabling adaptation to cabinet bodies 1 of various sizes, ensuring smooth sliding of the cabinet door 2, and improving sliding smoothness.

[0026] Preferably, the other rope segments of the sliding rope member 3 are formed by winding around the two guide pulley assemblies for one circle, causing the other rope segments of the sliding rope member 3 to wind around the guide pulleys at a circumferential angle of approximately 90°, which also enables the sliding rope member 3 as a whole to form a substantially square winding structure, adapting to cabinet bodies 1 of various sizes, ensuring smooth sliding of the cabinet door 2, and improving sliding smoothness.

[0027] It should be noted that the circumferential angle at which one synchronous rope segment of the sliding rope member 3 winds around the guide pulleys in the guide pulley assembly is 180°±Y, and the circumferential angle at which the other rope segments of the sliding rope member 3 wind around the guide pulleys in the guide pulley assembly is 90°±X, where X and Y are tolerances.

[0028] Preferably, the two guide pulley assemblies are a first guide pulley assembly and a second guide pulley assembly, the second guide pulley assembly comprises a first guide pulley 41 and a fourth guide pulley 44 arranged in a front-rear direction, and the first guide pulley assembly comprises a second guide pulley 42 and a third guide pulley 43 arranged in the front-rear direction; in the illustrated embodiment, the front-rear direction is the width direction of the cabinet body 1. In the illustrated embodiment, the first guide pulley assembly is arranged at the upper side, and the second guide pulley assembly is arranged at the lower side. Certainly, in other embodiments, the first guide pulley assembly may be arranged at the lower side, and the second guide pulley assembly may be arranged at the upper side.

[0029] The two connection members are a first connection member 51a and a second connection member 51b, one end of the sliding rope member 3 is connected to the second connection member 51b, and the other end of the sliding rope member 3 is successively wound around the first guide pulley 41, the second guide pulley 42, the third guide pulley 43, the second guide pulley 42, the third guide pulley 43, and the fourth guide pulley 44, and is then arranged on the second connection member 51b. In the illustrated embodiment, the first connection member 51a is arranged at the upper side, and the second connection member 51b is arranged at the lower side. Certainly, in other embodiments, the first connection member 51a may be arranged at the lower side, and the second connection member 51b may be arranged at the upper side.

[0030] The two synchronous rope segments are a first synchronous rope segment 31a and a second synchronous rope segment 31b, the second synchronous rope segment 31b is a rope segment between the first guide pulley 41 and the fourth guide pulley 44 and is connected to the second connection member 51b, and the first synchronous rope segment 31a is a rope segment between the second guide pulley 42 and the third guide pulley 43 and is connected to the first connection member 51a. In the illustrated embodiment, the first synchronous rope segment 31a is arranged at the upper side, and the second synchronous rope segment 31b is arranged at the lower side. Certainly, in other embodiments, the first synchronous rope segment 31a may be arranged at the lower side, and the second synchronous rope segment 31b may be arranged at the upper side.

[0031] The winding structure of the synchronous sliding mechanism in the present embodiment forms a substantially square winding structure by winding around the first guide pulley 41, the second guide pulley 42, the third guide pulley 43, and the fourth guide pulley 44. The specific winding sequence is: an end of the sliding rope member 3 is connected to the second connection member 51b, and an opposite end of the sliding rope member 3 is successively wound around the first guide pulley 41, the second guide pulley 42, the third guide pulley 43, the second guide pulley 42, the third guide pulley 43, and the fourth guide pulley 44, and is then connected to the second connection member 51b, forming a closed-loop winding structure.

[0032] It should be noted that the portion of the sliding rope member 3 wound from the third guide pulley 43 toward the second guide pulley 42 forms the first synchronous rope segment 31a, and the first synchronous rope segment 31a is part of a rope segment formed by the sliding rope member 3 being wound around one of the guide pulley assemblies for one circle.

[0033] Simultaneously, the sliding rope member 3 itself forms the first synchronous rope segment 31a between the second guide pulley 42 and the third guide pulley 43, and forms the second synchronous rope segment 31b between the first guide pulley 41 and the fourth guide pulley 44. Since the first synchronous rope segment 31a and the second synchronous rope segment 31b may move synchronously in the same direction, the two connection members are caused to move synchronously in the same direction, thereby ensuring smooth movement of the cabinet door 2.

[0034] Preferably, the first guide pulley 41 and the second guide pulley 42 are aligned in the up-down direction, the third guide pulley 43 and the fourth guide pulley 44 are aligned in the up-down direction, and the first connection member 51a and the second connection member 51b are aligned in the up-down direction. In such an arrangement, the sliding rope member 3 may better form a square winding structure at the guide pulleys, better ensuring smooth sliding of the cabinet door 2 and further improving sliding smoothness.

[0035] In the illustrated embodiment, the second guide pulley 42 is located above the first guide pulley 41, and the third guide pulley 43 is located above the fourth guide pulley 44. Certainly, in other embodiments, the first guide pulley 41 may also be located above the second guide pulley 42, and the fourth guide pulley 44 may also be located above the third guide pulley 43.

[0037] Preferably, the sliding rope member 3 comprises two segments, namely a first sliding rope segment and a second sliding rope segment, and the two connection members are a first connection member 51a and a second connection member 51b; an end of the first sliding rope segment is connected to the second connection member 51b, and an opposite end of the first sliding rope segment is successively wound around the first guide pulley 41, the second guide pulley 42, and the third guide pulley 43, and is then connected to the first connection member 51a; an end of the second sliding rope segment is connected to the first connection member 51a, and an opposite end of the second sliding rope segment is successively wound around the second guide pulley 42, the third guide pulley 43, and the fourth guide pulley 44, and is then connected to the first connection member 51a. In such an arrangement, by providing the sliding rope member 3 in two segments, the tensioning and assembly of the sliding rope member 3 is facilitated, improving assembly efficiency. It should be understood that the synchronous sliding mechanism of this embodiment may achieve movement of the cabinet door 2 specifically through one sliding rope member 3, or specifically through the sliding rope member 3 in two segments.

[0038] Preferably, the connection member is provided with a first mounting through hole 512 and a second mounting through hole 515 arranged in the up-down direction; an end of the sliding rope member 3 is mounted in the second mounting through hole 515 of the second connection member 51b, and an opposite end of the sliding rope member 3 is successively wound around the first guide pulley 41, the second guide pulley 42, the third guide pulley 43, the second guide pulley 42, the third guide pulley 43, and the fourth guide pulley 44, and is then mounted in the first mounting through hole 512 of the second connection member 51b; the first synchronous rope segment 31a is mounted in the second mounting through hole 515 of the first connection member 51a; a spacing between the first mounting through hole 512 and the second mounting through hole 515 is equal to a diameter of a pulley in the guide pulley assembly.

[0039] The synchronous sliding mechanism of the present embodiment facilitates the assembly and installation of the sliding rope member 3 with the first connection member 51a and the second connection member 51b by providing the first mounting through hole 512 and the second mounting through hole 515 on the connection member. Moreover, the spacing between the first mounting through hole 512 and the second mounting through hole 515 is equal to the diameter of the guide pulley, allowing both the first connection member 51a and the second connection member 51b to be interchangeable, thereby improving the versatility of components.

[0040] Specifically, an end of the sliding rope member 3 is connected to the second mounting through hole 515 of the second connection member 51b, and an opposite end of the sliding rope member 3 is successively wound around the first guide pulley 41, the second guide pulley 42, the first mounting through hole 512 of the first connection member 51a, the third guide pulley 43, the second mounting through hole 515 of the first connection member 51a, the second guide pulley 42, the first mounting through hole 512 of the first connection member 51a, the third guide pulley 43, and the fourth guide pulley 44, and is then arranged on the second connection member 51b.

To prevent unnecessary interference between the reverse rope segment 31c and the first connection member 51a, the reverse rope segment 31c passes through the first mounting through hole 512 of the first connection member 51a, improving the sliding smoothness of the sliding rope member 3 while also making the structure more compact.

Thus, the synchronous sliding mechanism of the present embodiment, by providing the connector 513 and the threaded adjustment member 514, allows the threaded adjustment member 514 to abut against the outer side of the second connection member 51b. When it is necessary to adjust the tension of the sliding rope member 3, the user may rotate the threaded adjustment member 514 to adjust the spacing between the threaded adjustment member 514 and the connector 513, indirectly adjusting the tension of the sliding rope member 3 to suit the actual application environment or cabinet bodies 1 of different sizes.

[0045] The two connection plates 511 in the second connection member 51b are a front connection plate 511a and a rear connection plate 511b; the connector 513 passes through the second mounting through hole 515 of the rear connection plate 511b of the second connection member 51b, and one end of the threaded adjustment member 514 extends out of the second mounting through hole 515 of the front connection plate 511a of the second connection member 51b and is clamped to the front connection plate 511a. In such an arrangement, the threaded adjustment member 514 abuts against the outer side of the front connection plate 511a of the second connection member 51b, allowing adjustment of the spacing between the threaded adjustment member 514 and the connector 513, thereby indirectly adjusting the tension of the sliding rope member 3 to suit the actual application environment or cabinet bodies 1 of different sizes.
