[0036] An embodiment of the present application provides a furniture product having a telescopic structure. Under the action of the telescopic structure, the furniture product can achieve multi-level telescopic adjustment. The telescopic adjustment can be the load-bearing area adjustment in the length direction of the furniture product or the load-bearing area adjustment in the width direction of the furniture product to meet the telescopic needs of different users.

[0037] In the embodiment of the present application, the furniture product may be a sofa, a bed, a table or a chair. In particular, when the sofa uses the telescopic structure of the present application, the extension of the length direction of the sofa can achieve multi-level length adjustment, which can not only meet the user's usage needs in different scenarios, but also when the extended length of the sofa reaches the maximum, the sofa can be adjusted into a sofa bed so that the user can lie flat vertically.

[0038] Reference Figure 1 and Figure 2 The present application provides a telescopic structure, which includes a frame 100, a first frame 200, at least one second frame 300 and a linkage mechanism.

[0039] The frame 100 is the main part of the entire telescopic structure. Figure 3 As shown, the frame 100 has a bearing area, a portion of the frame 100 is hollowed out to form the bearing area, and other components are arranged on the frame 100 and are in the bearing area.

[0040] The first frame 200 is slidably disposed on the frame 100, and the first frame 200 fills the vacant position of the bearing area to form a bearing surface. When the telescopic structure of the present application is used for a sofa, a seat bag or a cushion can be placed on the bearing surface. The first frame 200 can be extended or retracted from the frame 100, and the telescopic direction of the first frame 200 is parallel to the bearing surface. The extended portion of the first frame 200 can be used as an extension of the bearing surface.

[0041] There is at least one second frame 300 , and the second frame 300 is hidden in the frame 100 . The second frame 300 can slide in a direction perpendicular to the carrying surface, that is, the second frame 300 can also fill the empty position of the carrying area.

[0042] In the embodiment of the present application, the first frame 200 is connected to the second frame 300 through a linkage mechanism, and the linkage structure is set on the frame 100. During the extension of the first frame 200, the first frame 200 drives the second frame 300 to adjust to a vacant position filling the load-bearing area through the linkage mechanism. During the retraction of the first frame 200, the first frame 200 drives the second frame 300 through the linkage mechanism to be hidden in the frame 100.

[0043] Specifically, in a normal state, the first frame 200 is in the load-bearing area, the first frame 200 fills the vacant position of the load-bearing area to form a load-bearing surface, and the second frame 300 is hidden in the frame 100, and the overall structure is compact and ingenious.

[0044] When it is necessary to extend and expand the bearing surface, the first frame 200 extends out of the frame 100. When the first frame 200 is extended, the second frame 300 is driven to move through the linkage mechanism. The linkage mechanism converts the horizontal extension and contraction of the first frame 200 into the vertical sliding adjustment of the second frame 300. After the first frame 200 is extended to a preset position, the part of the first frame 200 extending out of the frame 100 serves as an extension of the bearing surface, and the second frame 300 also slides from the frame 100 to the bearing area, and the second frame 300 fills the vacant position in the bearing area due to the extension of the first frame 200 to complete the expansion and extension of the bearing surface.

[0045] It should be noted that, during the extension adjustment, after the first frame 200 is extended to the proper position, the second frame 300 also slides to the proper position.

[0046] When the bearing surface needs to be retracted, the first frame 200 is retracted and drives the second frame 300 to slide and be hidden in the frame 100 through the linkage mechanism.

[0047] It should be noted that, during the retraction adjustment, the second frame 300 is adjusted to the correct position before the first frame 200 to avoid movement interference between the second frame 300 and the first frame 200.

[0048] When multiple second frames 300 are provided, each second frame 300 is connected to the frame 100 through a linkage mechanism. As the first frame 200 is continuously extended and adjusted, multiple second frames 300 sequentially fill the positions of the load-bearing area that are vacant due to the extension of the first frame 200, so that the telescopic structure of the present application can achieve multi-stage telescopic adjustment and extension to meet different telescopic requirements. When performing multi-stage retraction adjustment, the second frame 300 that slides to fill the load-bearing area last slides to be hidden in the frame 100 first, and the second frame 300 that slides to fill the load-bearing area first slides to be hidden in the frame 100 last, so that during the adjustment process, the adjustment of the entire load-bearing surface is relatively continuous.

[0049] Due to the existence of the linkage mechanism, the first frame 200 and the second frame 300 can be adjusted in linkage, which is convenient. When applied to a sofa, the user can perform multi-level adjustment according to the needs to meet the needs of lying flat.

[0050] In some specific embodiments, Figure 3 As shown, the frame 100 includes a base frame 110, and enclosures 120 are arranged on both sides of the base frame 110 in the vertical direction, so that the frame 100 is U-shaped, and the two sides of the first frame body 200 are respectively connected to the inner sides of the two enclosures 120 by sliding through the first slide rails 710, and the first slide is arranged in the horizontal direction. The enclosure 120 is provided with a connecting portion 150, and the side of the second frame body 300 is slidably connected to the connecting portion 150 of the enclosure 120 through the second slide rail 720, and the second slide rail 720 is arranged in the vertical direction. The overall structure is simple, and subsequent assembly and maintenance are convenient.

[0051] In some embodiments, the linkage mechanism includes a first trigger assembly 500 and a second trigger assembly 600. The second trigger assembly 600 is connected between the second frame 300 and the frame 100. The first trigger assembly 500 is disposed on the frame 100. When the first trigger assembly 500 follows the movement of the first frame 200, the first trigger assembly 500 pushes against the second trigger assembly 600 so that the second trigger assembly 600 can be expanded or contracted in a direction perpendicular to the bearing surface. The expansion of the second trigger assembly 600 drives the second frame 300 to slide to the filling bearing area, and the contraction of the second trigger assembly 600 drives the second frame 300 to slide to hide in the frame 100. The sliding distance of the second frame 300 can be controlled by controlling the expansion distance of the second trigger assembly 600.

[0052] In some examples, the telescopic structure further includes a sliding member 440, the sliding member 440 includes a first connecting arm 420 and a second connecting arm 430, and the sliding member 440 is slidably disposed on the frame 100, specifically, as Figure 3 As shown, the frame 100 is provided with a guide column 140, and the sliding member 440 is sleeved on the guide column 140, and the sliding direction of the sliding member 440 is parallel to the extension direction of the first frame 200, the first connecting arm 420 is connected to the first frame 200, and the second connecting arm 430 is used for the installation of the first trigger assembly 500, so that when the first frame 200 extends and retracts, the sliding member 440 can follow the sliding action.

[0053] Furthermore, the frame 100 is also provided with an inner support member 130 for installing the second trigger assembly 600 .

[0054] Some examples include Figure 4 and Figure 5 As shown, the first trigger assembly 500 includes a first trigger member 510 capable of rebounding, and the second trigger assembly 600 includes a second trigger member 630 , and a portion of the second trigger member 630 is located on the movement path of the first trigger member 510 .

[0055] In some specific embodiments, the first trigger member 510 can be made of an elastic material, which can be rubber, springs or elastomeric. Therefore, when an external force acts on the first trigger member 510, the first trigger member 510 can be deformed, and after the external force disappears, the second trigger member 630 can be restored. When the first frame 200 is extended or retracted, when the first trigger member 510 passes the position where the second trigger member 630 is located, the first trigger member 510 pushes against the part of the second trigger member 630. Since the first trigger member 510 can be elastically deformed, when the second trigger assembly 600 is fully extended or retracted, the second trigger member 630 will no longer move with the movement of the first trigger member 510. Therefore, the first trigger member 510 is deformed when the pushing force is large enough to make the first trigger member 510 and the second trigger member 630 slip off, so that the first frame 200 can continue to extend or retract, and the second trigger assembly 600 is also extended or retracted.

[0056] Of course, in some embodiments, the first trigger member 510 mentioned here being able to rebound may also mean that the position state of the first trigger member 510 can be changed when the external force is large enough, and the rebound of the first trigger member 510 needs to be achieved through a rebound structure. Therefore, when the second trigger member 630 is pushed into place, the first trigger member 510 overcomes the force provided by the rebound structure under the action of external force and produces a change in position state, so that the first trigger member 510 is no longer pushed against the second trigger member 630, so that the first frame 200 can continue to extend or retract, and at the same time, the expansion or contraction of the second trigger component 600 is also achieved.

[0057] In some embodiments shown in this application, Figure 4 As shown, the first trigger component 500 also includes a rebound member 520, and the first trigger member 510 is configured to be rotatable. The first trigger member 510 is used to pull one end of the first trigger member 510 so that the length direction of the first trigger member 510 is perpendicular to the bearing surface, wherein the rotation center of the first trigger member 510 is close to the middle of the first trigger member 510, the rotation center axis of the first trigger member 510 is parallel to the bearing surface, and the rotation center axis of the first trigger member 510 is perpendicular to the extension direction of the first frame 200.

[0058] Specifically, the rebound member 520 is a spring, and the first trigger member 510 is hinged to the second connecting arm 430 so that the first trigger member 510 can rotate. The second connecting arm 430 is provided with a limit plate 530 for limiting the rotation angle of the first trigger member 510. One end of the spring is fixed to the second connecting arm 430, and the other end is connected to the end of the first trigger member 510 so that the first trigger member 510 is in a vertical state. Therefore, no matter whether the second trigger assembly 600 is in an expanded state or a contracted state, the second trigger member 630 is in the movement path of the first trigger member 510. Therefore, no matter whether the first frame 200 is extended or retracted, the second trigger member 630 can be driven to move through the first trigger member 510, and then the second frame 300 can be driven to move.

[0059] When the second trigger assembly 600 is in a retracted state, the second trigger member 630 is located between the rotation center axis of the first trigger member 510 and the rebound member 520; when the second trigger assembly 600 is in an expanded state, the second trigger member 630 is located between the rotation center axis of the first trigger member 510 and the bearing surface.

[0060] When the first frame 200 is extended or retracted, after the second frame 300 slides into place, the second trigger member 630 cannot be pushed, and the resulting pushing force causes the first trigger member 510 to overcome the tensile force of the spring to rotate and slip off the second trigger member 630. After the first trigger member 510 and the second trigger member 630 slip off, they can be restored to a vertical state under the action of the spring, so that the next second trigger member 630 can still be pushed by the first trigger member 510, without affecting the subsequent multi-stage telescopic adjustment.

[0061] In some embodiments, Figure 5 As shown, the second trigger assembly 600 includes a first connecting member 610 and a second connecting member 620 which are rotatably connected to each other, one end of the first connecting member 610 is rotatably connected to the second frame 300, and one end of the second connecting member 620 is rotatably connected to the frame 100. A limiting component is provided on the frame 100, and the limiting component is used to limit the rotation angle of the second connecting member 620.

[0062] In the embodiment of the present application, the second trigger member 630 is disposed on the second connecting member 620, and the first connecting member 610 and the second connecting member 620 that are rotatably connected to each other form a connecting rod structure, and the second frame 300 is configured to be able to slide in the vertical direction, so when the first trigger member 510 pushes against the second trigger member 630, the horizontal movement of the first trigger member 510 can be converted into the vertical sliding of the second frame 300. The rotation angle of the second connecting member 620 is limited by the limiting member, and under the deadweight of the second frame 300 itself, the second trigger assembly 600 can be maintained in an expanded or contracted state.

[0063] In some embodiments, Figure 5 As shown, the limiting component includes a first limiting component 640 and a second limiting component 650, and the second connecting component 620 is located between the first limiting component 640 and the second limiting component 650. When the second connecting component 620 abuts against the first limiting component 640, the second trigger assembly 600 is in an expanded state, and when the second connecting component 620 abuts against the second limiting component 650, the second trigger assembly 600 is in a contracted state.

[0064] Among them, in the expanded state, the angle between the first connecting member 610 and the second connecting member 620 is an obtuse angle, which, together with the weight of the second frame 300 itself and the restriction of the first limiting member 640, can achieve self-locking, ensuring that the second trigger assembly 600 can be maintained in the expanded state and the second frame 300 is in a state of filling the load-bearing area; in the retracted state, the angle between the first connecting member 610 and the second connecting member 620 is an acute angle, which, together with the weight of the second frame 300 itself and the restriction of the second limiting member 650, can achieve self-locking, ensuring that the second trigger assembly 600 can be maintained in the retracted state and the second frame 300 is in a state hidden in the frame 100.

[0065] In some embodiments, Figure 6 As shown, the first frame 200 includes a support leg 220, which is used to support the first frame 200 after the first frame 200 extends out of the frame 100. In order to reduce the friction between the support leg 220 and the ground when the first frame 200 is extended, a roller 230 is provided on the support leg 220 to facilitate the extension and retraction of the first frame 200.

[0066] In some examples, the first frame 200 includes two connecting bars 210, and the connecting bars 210 are slidably connected to the enclosure 120 of the frame 100 through the first slide rail 710. In order to enable the first frame 200 to be used for bearing, a support bar can be provided between the two connecting bars 210 to improve the rigidity of the first frame 200.

[0067] In some embodiments, the telescopic structure of the present application may be provided with a driving assembly 400, which may be an electric push rod 410, a cylinder or an oil cylinder. In the embodiment shown in the present application, the driving assembly 400 is an electric push rod 410, which is fixed to the guide column 140, and the driving end of the electric push rod 410 is connected to the sliding member 440.

[0068] In some specific embodiments, three second frames 300 are provided in the present application, and the number of second trigger components 600 of the linkage mechanism is consistent with the number of second frames 300, so that multiple second frames 300 can be linked through a group of first trigger components 500, and the first frame 200 can also achieve three-level telescopic adjustment.

[0069] like Figures 7 to 9 As shown, during the first-level adjustment, the first frame 200 is extended to the preset first position under the action of the driving component 400. At this time, the first trigger member 510 drives the first second trigger member 630, and the second trigger member 630 adjusts the first group of second trigger components 600 to the unfolded state, thereby being able to drive the first second frame 300 to slide to fill the vacant position of the load-bearing area and make up for the missing position of the load-bearing surface of the load-bearing area.

[0070] like Fig.10 As shown, during the secondary adjustment, the first frame 200 is extended to the preset second position under the action of the driving component 400. At this time, the first trigger member 510 drives the second trigger member 630, and the second trigger member 630 adjusts the second group of second trigger components 600 to the unfolded state, thereby being able to drive the second second frame 300 to slide to fill the vacant position of the load-bearing area and make up for the missing position of the load-bearing surface of the load-bearing area.

[0071] like Fig.11As shown, during the third-level adjustment, the first frame 200 is extended to the preset third position under the action of the driving component 400. At this time, the first trigger member 510 drives the third second trigger member 630, and the second trigger member 630 adjusts the third group of second trigger components 600 to the unfolded state, thereby being able to drive the third second frame 300 to slide to fill the vacant position of the load-bearing area and make up for the missing position of the load-bearing surface of the load-bearing area.

[0072] Fig.12 and Fig.13 It is a schematic diagram of the retraction process of the telescopic structure, wherein, during retraction adjustment, the first frame 200 retracts to the preset second position under the action of the driving component 400, and the first trigger member 510 drives the third second trigger member 630, and the second trigger member 630 adjusts the third group of second trigger components 600 from the expanded state to the retracted state, thereby being able to drive the third second frame 300 to be hidden in the frame 100, and the subsequent retraction is also the same, which will not be elaborated again. It should be noted that when performing multi-level retraction adjustment, the second frame 300 that slides to the filling load-bearing area last slides to be hidden in the frame 100 first, and the second frame 300 that slides to the filling load-bearing area first slides to be hidden in the frame 100 last, so that the adjustment of the entire load-bearing surface is relatively continuous during the adjustment process.

[0073] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
