Description

Technical Field

[0001] This application relates to the field of sofa technology, and in particular to a modular sofa that is easy to move. Background Technology

[0002] With the continuous development of modern home life and people's increasing demands for the functionality and aesthetics of living spaces, sectional sofas have emerged. As the core furniture in leisure areas such as the living room, they accommodate various activities including rest, socializing, and entertainment. A sectional sofa typically consists of several independent single or double sofas that can be arranged relatively independently yet side-by-side, adapting to various scenarios, whether for large gatherings or dispersed use.

[0003] In existing technologies, the bottom support structure of modular sofas is mostly made of wood or metal legs.

[0004] Regarding the aforementioned technologies, the inventors believe that if modular sofas need to be frequently rearranged, users need to expend considerable effort to lift and push them. This is not only laborious and time-consuming, but long-term operation may also cause wear and deformation of the sofa legs, affecting the overall stability and lifespan of the sofa. Utility Model Content

[0005] The purpose of this application is to provide a modular sofa that is easy to move, so as to improve the problem that users have to exert a lot of effort to lift and push modular sofas when they need to be frequently rearranged.

[0006] This application provides a modular sofa for easy movement, employing the following technical solution:

[0007] A movable modular sofa includes a sofa body with legs on both sides of its bottom surface. A driving component is invertedly mounted on the bottom surface of the sofa body between the two legs. A cavity plate is slidably mounted on the output end of the driving component. A trapezoidal plate is mounted on one end of the output end of the driving component within the cavity plate. Slide plates are slidably mounted on both sides of the trapezoidal plate within the cavity plate. An inclined abutment is mounted on the end of the slide plate near the trapezoidal plate. An elastic element is connected between the inclined abutment surfaces on both sides of the trapezoidal plate. An insert plate is mounted on the side of the slide plate away from the trapezoidal plate. Through holes are provided on both sides of the cavity plate corresponding to the insert plate. Slots for the insert plates are provided on the inner sidewalls of the legs. Several casters are mounted on the bottom surface of the cavity plate.

[0008] By adopting the above technical solution, the trapezoidal plate is moved by the driving component, and the trapezoidal plate moves the cavity plate downward, so that the pulley touches the ground and supports the sofa body. As the trapezoidal plate moves downward, its inclined surface abuts against the inclined surface of the sliding plate and works with the elastic component to realize the insertion of the insert plate. The pulley abuts against the ground and supports the sofa body, which facilitates the movement of the sofa body. At the same time, the insert plate works stably with the driving component to fix the cavity plate, which improves the stability of the cavity plate during movement and helps to improve the movement stability of the sofa body.

[0009] Optionally, the trapezoidal plate is provided with a telescopic rod in the vertical direction, and the end of the telescopic rod away from the trapezoidal plate is connected to the inner top surface of the cavity plate.

[0010] By adopting the above technical solutions, it is helpful to improve the stability of the trapezoidal plate during the up-and-down movement, reduce its swaying or deviation, and thus improve the stability and reliability of the sofa body's movement function.

[0011] Optionally, several insert plates are evenly arranged.

[0012] By adopting the above technical solution, multiple inserts can increase the connection points between the hollow panel and the legs, making the connection between the two more stable and helping to improve the stability and safety of the sofa body movement.

[0013] Optionally, the end of the insert plate away from the trapezoidal plate is provided with a beveled surface.

[0014] By adopting the above technical solution, after the sofa has moved, when the driving component retracts, the combined action of gravity and the inclined plane helps the insert plate to automatically disengage from the slot, making it easy for the sofa to return to a fixed, immobile state without the need for additional manual operation, thus improving the convenience of use.

[0015] Optionally, a locking plate is provided inside the cavity plate and on both sides of the slide plate, and the locking plate is in contact with the sides of the slide plate.

[0016] By adopting the above technical solution, the locking plate limits the movement of the skateboard, allowing the skateboard to slide within a specified trajectory. This helps reduce the skateboard's deviation or wobbling during movement and improves the stability and accuracy of the insertion of the locking plate.

[0017] Optionally, the top surface of the locking plate is bent to form a bonding plate that fits against the top surface of the sliding plate.

[0018] By adopting the above technical solution, the bonding plate further increases the constraint on the skateboard, limiting the skateboard from the top and sides in all directions, making the movement of the skateboard more stable and precise, and further improving the stability and accuracy of the entire drive mechanism.

[0019] Optionally, the bottom surface of the support leg is provided with a limiting plate that can abut against the bottom surface of the cavity plate.

[0020] By adopting the above technical solution, the limiting plate restricts the downward movement distance of the cavity plate, preventing the cavity plate from moving too far downward and causing damage to the sofa. At the same time, it also helps the pulleys to contact the ground in the right position and support the sofa body.

[0021] Optionally, an elastic pad is provided on the side of the limiting plate near the cavity plate.

[0022] By adopting the above technical solution, when the cavity plate moves down and abuts against the limiting plate, the elastic pad can play a buffering role, reduce the impact force generated by the collision, reduce noise, help protect the cavity plate and the limiting plate, and extend the service life of the sofa.

[0023] In summary, this application includes at least one of the following beneficial technical effects of a movable modular sofa:

[0024] 1. The trapezoidal plate is moved by the driving component, which in turn moves the hollow plate downward, causing the pulley to touch the ground and support the sofa body. As the trapezoidal plate moves downward, its inclined surface abuts against the inclined surface of the sliding plate and works in conjunction with the elastic component to insert the insert plate. The pulley abuts against the ground to support the sofa body, making it easy to move the sofa body. At the same time, the insert plate, in conjunction with the driving component, stably fixes the hollow plate, improving the stability of the hollow plate during movement and helping to improve the movement stability of the sofa body.

[0025] 2. After the sofa has moved, when the drive mechanism retracts, the combined effect of gravity and the inclined plane helps the insert plate automatically disengage from the slot, making it easy for the sofa to return to a fixed, immobile state without requiring any additional manual operation, thus improving ease of use.

[0026] 3. The interlocking plate limits the movement of the skateboard, allowing it to slide within a specified trajectory. This helps reduce the skateboard's deviation or wobbling during movement and improves the stability and accuracy of the interlocking plate connection. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0032] A modular sofa that is easy to move, as shown in Figure 1, includes a sofa body 1, and legs 11 are provided on both sides of the bottom surface of the sofa body 1. The legs 11 are fixed to the bottom surfaces of the sofa body 1 in an integrated manner to support the sofa body 1.

[0033] Referring to Figure 1, a drive component 2, which is a cylinder, is invertedly installed on the bottom surface of the sofa body 1 between the two side legs 11. The bottom surface of the sofa body 1 has a mounting groove (not shown in the figure). The drive component 2 is bolted into the mounting groove. The inverted arrangement is to ensure that the output end of the drive component 2 faces downwards. A hollow plate 3 is slidably installed through the output end of the drive component 2. The hollow plate 3 is a plate-like structure with a hollow interior, providing installation space for subsequent components.

[0034] Referring to Figure 1, a limiting plate 7 is provided on the bottom surface of the support leg 11, which can abut against the bottom surface of the cavity plate 3. The limiting plate 7 and the support leg 11 are integrally connected to limit the downward movement distance of the cavity plate 3 and prevent the cavity plate 3 from moving downward excessively. An elastic pad 71 is provided on the side of the limiting plate 7 near the cavity plate 3. The elastic pad 71 is fixed to the limiting plate 7 by adhesive and is made of rubber material.

[0035] Refer to Figure 2. Figure 3 A trapezoidal plate 21 is provided at the output end of the drive component 2 and at one end located inside the cavity plate 3. The trapezoidal plate 21 is fixed to the output end of the drive component 2 by welding and has a trapezoidal structure. A telescopic rod 211 is provided along the vertical direction of the trapezoidal plate 21. The telescopic rod 211 includes a cylindrical part and a rod that is slidably inserted into the cylindrical part. The end of the telescopic rod 211 away from the trapezoidal plate 21 is connected to the top surface inside the cavity plate 3. Both ends of the telescopic rod 211 are connected by welding.

[0036] Refer to Figure 2. Figure 3Slide plates 4 are slidably mounted on both sides of trapezoidal plate 21 inside cavity plate 3. Slide plates 4 are slidably connected to cavity plate 3. An inclined abutment surface 41 is provided at the end of slide plate 4 near trapezoidal plate 21. The inclined abutment surface 41 cooperates with the inclined surface of trapezoidal plate 21. When trapezoidal plate 21 moves up and down, the inclined abutment surface 41 can push slide plate 4 to move left and right. An elastic element 42 is provided between the inclined abutment surfaces 41 on both sides of trapezoidal plate 21. The elastic element 42 is a spring. The two ends of the spring are respectively connected to the inclined abutment surfaces 41 of the two slide plates 4 through hooks. When trapezoidal plate 21 moves upward, the spring can make the two slide plates 4 return to their original position.

[0037] Refer to Figure 2. Figure 3 A locking plate 6 is provided inside the cavity plate 3 and on both sides of the slide plate 4. The locking plate 6 is integrally set inside the cavity plate 3 and fits against both sides of the slide plate 4. The top surface of the locking plate 6 is bent to provide a bonding plate 61 that fits against the top surface of the slide plate 4. The bonding plate 61 and the locking plate 6 are an integral structure. The locking plate 6 and the bonding plate 61 limit the slide plate 4 and ensure that the slide plate 4 can only slide within a specific track.

[0038] Refer to Figure 2. Figure 3 A plate 43 is provided on the side of the slide plate 4 away from the trapezoidal plate 21. The plate 43 is integrally connected to the slide plate 4. Several plates 43 are evenly distributed, preferably three in this embodiment. Through holes 31 are provided on both sides of the cavity plate 3 corresponding to the plate 43. The plate 43 can move inside and outside the cavity plate 3 through the through holes 31. The inner side wall of the support leg 11 is provided with a slot 111 that is adapted to the plate 43. When the plate 43 is inserted into the slot 111, the cavity plate 3 and the support leg 11 can be fixed together.

[0039] Reference Figure 3 The end of the insert plate 43 away from the trapezoidal plate 21 is provided with a beveled surface 431. The inner wall of the slot 111 abuts against the beveled surface 431 and under the action of gravity, the insert plate 43 is driven away from the slot 111. The design of the beveled surface 431 makes it easy for the insert plate 43 to be smoothly removed from the slot 111 when subjected to gravity and other forces.

[0040] Reference Figure 1 Figure 2 Figure 3 The bottom surface of the cavity plate 3 is provided with a number of pulleys 5. In this embodiment, four pulleys 5 are preferred. The pulleys 5 are fixed to the bottom surface of the cavity plate 3 by bolt connection.

[0041] The implementation principle of this application embodiment is as follows:

[0042] In actual use, when normally placed, the drive unit 2 retracts, the trapezoidal plate 21 is positioned higher, and the weight of the sofa body 1 is borne by the support leg 11, with the pulley 5 off the ground to ensure stability. When movement is required, the drive unit 2 is activated to extend its output end, causing the trapezoidal plate 21 to move downwards. At the same time, the cavity plate 3 moves downwards, and the inclined surface of the trapezoidal plate 21 opens the sliding plate 4, allowing the insert plate 43 to be inserted into the slot 111. At this time, the cavity plate 3 abuts against the elastic pad 71 of the limiting plate 7, and the pulley 5 touches the ground. The weight of the sofa body 1 is then borne by the pulley 5 to facilitate movement. This facilitates the movement and rearrangement of the sofa body 1.
