[0016] By adopting the technical scheme, the baffle is embedded in the embedding groove to shield the opening of the accommodating cavity of the first support frame, so that the end of the first sofa is closed and flat, thereby improving the appearance of the sofa chair; and when the adjusting assembly is in the second state, one end of the second sofa cushion also overlaps the baffle, so that the adjusting assembly is stably in the second state, thereby improving the stability of the second sofa in use.

[0017] Preferably, the second sofa further comprises a pull belt, the pull belt is arranged at an end of the second sofa cushion close to the baffle.

[0018] By adopting the technical scheme, the pull belt is arranged to facilitate pulling out the second support frame, and facilitate lifting the second sofa cushion upward, thereby facilitating switching the state of the adjusting assembly, and thereby facilitating adjusting the use mode of the second sofa.

[0019] Preferably, the first sofa further comprises a cleaning strip and a first elastic member, the first support frame is provided with a mounting groove at the embedding groove, the cleaning strip and the first elastic member are arranged in the mounting groove, and the first elastic member drives the cleaning strip to protrude out of the mounting groove.

[0020] By adopting the technical scheme, the cleaning strip and the first elastic member are arranged, and during the process of pulling out the second support frame from the accommodating cavity or pushing the second support frame into the accommodating cavity, the first elastic member drives the cleaning strip to protrude out of the mounting groove, so that the cleaning strip abuts against the second sofa cushion to clean dust or dirt on the surface of the second sofa cushion.

[0021] Preferably, the baffle is provided with a fixing groove at an end away from the second support frame, the cleaning strip is inserted into the fixing groove, and a first chamfer is arranged on a side of the cleaning strip away from the embedding groove.

[0022] By adopting the above technical solution, during the process of pushing the second support frame into the receiving cavity, the baffle presses the cleaning strip into the mounting groove through the first chamfer. Then, the baffle is embedded in the groove, so that the cleaning strip corresponds to the fixing groove. The first elastic element drives the cleaning strip to be inserted into the fixing groove to fix the baffle, thereby restricting the movement of the second support frame. This ensures the stability when the first sofa is used alone, and also allows the cleaning strip to be placed in a closed manner, reducing the accumulation of dust at the end of the cleaning strip.

[0023] Preferably, the second sofa further includes a top-mounted plate, a linkage plate, and a second elastic member. The top-mounted plate is slidably connected to the fixed groove and has a second chamfer at one end away from the cleaning strip. The baffle also has a movable groove communicating with the fixed groove on the side near the second support frame. The linkage plate and the second elastic member are both located in the movable groove. The second elastic member drives the linkage plate to protrude from the movable groove, and the linkage plate always abuts against the second chamfer of the top-mounted plate.

[0024] By adopting the above technical solution, when it is necessary to pull out the second support frame from the receiving cavity, the second sofa cushion is pulled by the pull strap. Since the cleaning strip is inserted into the fixing groove to restrict the movement of the first support frame, the end of the second sofa cushion is lifted and abuts against the linkage plate. The linkage plate lifts the ejector plate through the second chamfer and stretches the second elastic member, so that the ejector plate pushes the cleaning strip out of the fixing groove to release the fixation of the second support frame, thereby facilitating the removal of the second sofa.

[0025] Preferably, the first sofa further includes two guide rails, which are respectively disposed on the two inner side walls of the first support frame, and the second sofa further includes two guide wheels, which are disposed on the second support frame and slidably connected to the two guide rails.

[0026] By adopting the above technical solution and setting guide rails and guide wheels, the stability of the second support frame movement can be improved.

[0042] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0043] This application discloses an adjustable sofa chair.

[0044] Example 1:

[0045] Reference Figure 1 and Figure 2 The adjustable sofa chair includes a first sofa 1 and a second sofa 2. The first sofa 1 includes a first support frame 11 and a first sofa cushion 12. The first support frame 11 is in the shape of a rectangular box. A receiving cavity 111 is opened on the lower side of the first support frame 11 and the receiving cavity 111 extends to one end of the first support frame 11, so that one end of the first support frame 11 is open. The first sofa cushion 12 is fixedly connected to the upper side of the first support frame 11.

[0046] The second sofa 2 includes a second support frame 21, adjustment components 22, and a second sofa cushion 23. The second support frame 21 is rectangular and movably disposed within the receiving cavity 111. Multiple casters (not marked in the figure) are provided on the lower side of the second support frame 21 to facilitate its movement. In this embodiment, to improve the support effect on the second sofa cushion 23, two adjustment components 22 are used. The lower ends of the two adjustment components 22 are respectively disposed on the two inner side walls of the second support frame 21. The second sofa cushion 23 is fixedly connected to the upper ends of the two adjustment components 22, and the second sofa cushion 23 rises or falls under the control of the adjustment components 22.

[0047] In practical applications, the adjustable sofa chair has four usage modes. When the sofa chair is in the first usage mode, the second support frame 21 moves into the receiving cavity 111, so that the second sofa 2 is stored in the receiving cavity 111, and the first sofa 1 is used alone to meet the user's basic needs.

[0048] The user pulls the second support frame 21 out of the receiving cavity 111. There is a gap between the first sofa cushion 12 and the second sofa cushion 23, that is, the second sofa cushion 23 is lower than the first sofa cushion 12, so that the sofa chair is in the second use mode. The first sofa 1 and the second sofa 2 can be used at the same time, which can be used for users of different heights, and can also provide more seats. The second sofa 2 can provide a place for the user sitting on the first sofa 1 to put their feet, so as to meet the different needs of the users.

[0049] After the user pulls the second support frame 21 out of the receiving cavity 111, the second sofa cushion 23 is raised by the two adjustment components 22. At this time, the second sofa cushion 23 is flush with the first sofa cushion 12, so that the sofa chair is in the third use mode. The first sofa 1 and the second sofa 2 work together to allow the user to lie down, further meeting the different needs of the user.

[0050] After the user pulls the second support frame 21 out of the receiving cavity 111 and separates the second support frame 21 from the first support frame 11, the first sofa 1 and the second sofa 2 can be used independently, putting the sofa chairs into a fourth usage mode, thus making them suitable for different usage scenarios. It should be noted that when the sofa chairs are in the second, third, and fourth usage modes, the receiving cavity 111 can be used to place items.

[0051] In summary, by pulling out the second support frame 21 and raising or lowering the second sofa cushion 23 via the adjustment component 22, the adjustable sofa chair has multiple usage modes to increase its functionality and meet the different needs of users.

[0052] Reference Figure 3 and Figure 4In some embodiments, the adjustment assembly 22 includes a support plate 221, a first connecting rod 222, a second connecting rod 223, a third connecting rod 224, a fourth connecting rod 225, and an abutment piece 226. The support plate 221 is a right-angled plate and is located above the second support frame 21. The upper ends of the first connecting rod 222 and the second connecting rod 223 are respectively rotatable to the two ends of the support plate 221. The lower end of the second connecting rod 223 is rotatably connected to one end of the third connecting rod 224, and one end of the third connecting rod 224 and the lower end of the first connecting rod 222 are both rotatably connected to the second support frame 21. One end of the fourth connecting rod 225 is rotatably connected to the middle position of the second connecting rod 223 near the second connecting rod 223, and the other end is rotatably connected to the second support frame 21. The center of the circle where the third connecting rod 224 is rotatably connected to the second support frame 21 is located between the center of the circle where the first connecting rod 222 is rotatably connected to the second support frame 21 and the center of the circle where the fourth connecting rod 225 is rotatably connected to the second support frame 21. The abutment piece 226 is located on the side of the second link 223 away from the second link 223, and is located on the side of the second link 223 away from the first link 222 (that is, the side of the second link 223 rotatably connected to the center of the second support frame 21 away from the center of the first link 222).

[0053] The adjustment component 22 has a first state and a second state. Specifically, when the adjustment component 22 is in the first state, the end of the fourth link 225 away from rotation is lower than the abutment piece 226, meaning the abutment piece 226 cannot abut and limit the fourth link 225. This causes the upper ends of the first link 222 and the second link 223 to move downwards after rotation, so that the support plate 221 overlaps the upper side of the second support frame 21, and the second sofa cushion 23 also overlaps the second support frame 21. This allows the adjustment component 22 to drive the second sofa cushion 23 to descend, so that the second sofa 2 can be placed in the receiving cavity 111. When the adjustment component 22 is in the second state, the fourth link 225 abuts against the abutment piece 226, so that the second sofa cushion 23 is flush with the first sofa cushion 12. This allows the adjustment component 22 to drive the second sofa cushion 23 to rise.

[0054] The state switching operation of the adjustment component 22 is as follows: After pulling the second support frame 21 out of the receiving cavity 111, the second sofa cushion 23 is lifted upwards at its outer end (i.e., the end of the second sofa cushion 23 away from the first support frame 11), causing the first connecting rod 222, the second connecting rod 223, the third connecting rod 224, and the fourth connecting rod 225 to rotate. The end of the fourth connecting rod 225 away from rotation is higher than the abutment piece 226. Then, the second sofa cushion 23 is pushed towards the end closer to the first support frame 11, causing the fourth connecting rod 225 to abut against the abutment piece 226, thus completing the switching of the adjustment component 22 from the first state to the second state. Similarly, repeating the above actions can switch the adjustment component 22 from the second state to the first state, thereby facilitating the raising or lowering of the second sofa cushion 23. It should be noted that the adjustment component 22 has a simple structure and is easy to operate for switching states, and the adjustment component 22 can stably maintain the first or second state, thereby improving the stability of the second sofa cushion 2 in use.

[0055] In some embodiments, the adjustment assembly 22 further includes a mounting rod 227, which is fixedly connected to the inner wall of the second support frame 21 by bolts. One end of the first connecting rod 222, the third connecting rod 224, and the fourth connecting rod 225 are all rotatably connected to the mounting rod 227, so that the first connecting rod 222, the third connecting rod 224, and the fourth connecting rod 225 are rotatably connected to the second support frame 21, and the abutment piece 226 is also fixedly connected to the mounting rod 227. During the installation of the adjustment assembly 22, it is only necessary to assemble all the components of the adjustment assembly 22, and finally fix the mounting rod 227 to the second support frame 21 by bolts, thereby facilitating the assembly of the adjustment assembly 22.

[0056] Reference Figure 2 and Figure 5 In some embodiments, the second sofa 2 further includes a baffle 24, which is fixedly connected to the end of the second support frame 21 away from the first support frame 11 and is higher than the second support frame 21. Correspondingly, the end of the first support frame 11 near the second support frame 21 has a groove 112. When the second sofa 2 is placed in the receiving cavity 111, the baffle 24 is embedded in the groove 112 to cover the opening of the receiving cavity 111 of the first support frame 11, so that the end of the first sofa 1 is closed and flat, thereby improving the aesthetics of the sofa chair. Furthermore, when the adjustment component 22 is in the second state, one end of the second sofa cushion 23 also overlaps with the baffle 24, and the end of the second sofa cushion 23 away from the baffle 24 abuts against the first sofa cushion 12 and the first support frame 11, which enables the adjustment component 22 to be stably in the second state, thereby improving the stability of the second sofa 2 in use.

[0057] In some embodiments, the second sofa 2 further includes a pull strap 25, which is fixedly connected to one end of the second sofa cushion 23 near the baffle 24. By pulling the pull strap 25, the second support frame 21 can be pulled out, and the second sofa cushion 23 can be lifted upwards, which facilitates switching the state of the adjustment component 22, thereby raising or lowering the second sofa cushion 23, and thus adjusting the usage mode of the sofa chair.

[0058] Reference Figure 5 In some embodiments, the first sofa 1 further includes two guide rails 13, which are fixedly connected to the two inner side walls of the first support frame 11. The second sofa 2 further includes two guide wheels 26, which are fixedly connected to the two sides of the second support frame 21 away from the baffle 24, and the two guide wheels 26 are slidably connected to the two guide rails 13 to improve the stability of the movement of the second support frame 21.

[0059] In some embodiments, the first sofa 1 further includes two stops 14, which are fixedly connected to the two inner sidewalls of the first support frame 11 and located at one end of the guide rail 13 near the second support frame 21. These stops restrict further movement of the second support frame 21, allowing the user to judge when to lift the second sofa cushion 23, thus facilitating the user to raise the second sofa 2 using the adjustment assembly 22. It should be noted that the second support frame 21 can be separated from the first support frame 11 by lifting the end of the second support frame 21 away from the baffle 24.

[0060] The implementation principle of this embodiment is as follows: In practical applications, the adjustable sofa chair has four usage modes. When the sofa chair is in the first usage mode, the second support frame 21 moves into the receiving cavity 111, so that the second sofa 2 is stored in the receiving cavity 111, and the first sofa 1 is used alone to meet the user's basic needs.

[0061] The user pulls the second support frame 21 out of the receiving cavity 111. There is a gap between the first sofa cushion 12 and the second sofa cushion 23, that is, the second sofa cushion 23 is lower than the first sofa cushion 12, so that the sofa chair is in the second use mode. The first sofa 1 and the second sofa 2 can be used at the same time, which can be used for users of different heights, and can also provide more seats. The second sofa 2 can provide a place for the user sitting on the first sofa 1 to put their feet, so as to meet the different needs of the users.

[0062] After the user pulls the second support frame 21 out of the receiving cavity 111, the second sofa cushion 23 is raised by the two adjustment components 22. At this time, the second sofa cushion 23 is flush with the first sofa cushion 12, so that the sofa chair is in the third use mode. The first sofa 1 and the second sofa 2 work together to allow the user to lie down, further meeting the different needs of the user.

[0063] After the user pulls the second support frame 21 out of the receiving cavity 111 and separates the second support frame 21 from the first support frame 11, the first sofa 1 and the second sofa 2 can be used independently, putting the sofa chairs into a fourth usage mode, thus making them suitable for different usage scenarios. It should be noted that when the sofa chairs are in the second, third, and fourth usage modes, the receiving cavity 111 can be used to place items.

[0064] In summary, by pulling out the second support frame 21 and raising or lowering the second sofa cushion 23 via the adjustment component 22, the adjustable sofa chair has multiple usage modes to increase its functionality and meet the different needs of users.

[0065] Example 2:

[0066] Reference Figure 6 This embodiment is identical to Embodiment 1 in all other structures except that the first sofa 1 further includes a cleaning strip 15 and a first elastic element 16. The first support frame 11 has an installation groove 113 on the top wall of the recess 112. The cleaning strip 15 is a hard board with a brush bristle or brush blade at the lower end. The first elastic element 16 is a spring and there are multiple springs. The cleaning strip 15 and the multiple first elastic elements 16 are all located in the installation groove 113. One end of the multiple first elastic elements 16 is fixedly connected to the upper end of the cleaning strip 15, and the other end is fixedly connected to the top wall of the first support frame 11 located in the installation groove 113, so as to drive the cleaning strip 15 to protrude from the installation groove 113. When the baffle 24 is embedded in the groove 112, the cleaning strip 15 abuts against the upper end of the baffle 24. During the process of pulling the second support frame 21 out of the receiving cavity 111 or pushing the second support frame 21 into the receiving cavity 111, the first elastic member 16 drives the cleaning strip 15 to protrude out of the mounting groove 113, so that the bristles or brush blades at the lower end of the cleaning strip 15 abut against the second sofa cushion 23 to clean the dust or dirt on the surface of the second sofa cushion 23.

[0067] Reference Figure 6 and Figure 7In some embodiments, the upper end of the baffle 24 is provided with a fixing groove 241. When the baffle 24 is embedded in the groove 112, the cleaning strip 15 is inserted into the fixing groove 241 to fix the baffle 24, thereby restricting the movement of the second support frame 21. This ensures the stability when the first sofa 1 is used alone and also allows the cleaning strip 15 to be enclosed, reducing dust accumulation on the bristles or brush blades of the cleaning strip 15. Furthermore, the outer side of the cleaning strip 15 is provided with a first chamfer 151. During the process of pushing the second support frame 21 into the receiving cavity 111, the baffle 24 presses the cleaning strip 15 into the mounting groove 113 through the first chamfer 151. Afterward, the baffle 24 is embedded in the groove 112, so that the cleaning strip 15 corresponds to the fixing groove 241. The first elastic member 16 drives the cleaning strip 15 to be inserted into the fixing groove 241, thereby realizing the automatic insertion of the cleaning strip 15 into the fixing groove 241.

[0068] Reference Figure 7 and Figure 8 In some embodiments, the second sofa 2 further includes a top-mounted plate 27, a linkage plate 28, and a second elastic member 29. The top-mounted plate 27 is slidably connected to the fixed groove 241 in the vertical direction, and the lower end of the top-mounted plate 27 is provided with a second chamfer 271. The baffle 24 has a movable groove 242 on the side near the second support frame 21, and the movable groove 242 is connected to the fixed groove 241. The linkage plate 28 and the second elastic member 29 are both provided in the movable groove 242. The second elastic member 29 is a spring, one end of which is fixedly connected to the baffle 24, and the other end is fixedly connected to the linkage plate 28, so as to drive one end of the linkage plate 28 to protrude out of the movable groove 242, and the other end of the linkage plate 28 always abuts against the second chamfer 271 of the top-mounted plate 27. It should be noted that when the adjustment component 22 is in the first state, there is a gap between the second sofa cushion 23 and the baffle 24, and the two sides of the linkage plate 28 protruding from the movable groove 242 are provided with chamfers.

[0069] When the second support frame 21 needs to be pulled out of the receiving cavity 111, the second sofa cushion 23 is pulled by the pull strap 25. Since the cleaning strip 15 is inserted into the fixing groove 241 to restrict the movement of the first support frame 11, the end of the second sofa cushion 23 is lifted and abuts against the linkage plate 28. The linkage plate 28 lifts the ejector plate 27 through the second chamfer 271 and stretches the second elastic member 29, so that the ejector plate 27 pushes the cleaning strip 15 out of the fixing groove 241 to release the fixation of the second support frame 21. There is no need to set up other structures to make the cleaning strip 15 disengage from the fixing groove 241. While maintaining the original usage method, the fixation of the second support frame 21 can be automatically released, which makes it easy for the sofa chair to change to different usage modes.
