Description

Technical Field

[0001] This utility model relates to the field of sofa leg technology, specifically to a sofa leg with a cushioning structure. Background Technology

[0002] In the furniture industry, sofa legs are crucial components that support the overall weight of a sofa and maintain its stability. Traditionally, sofa legs are mostly made of wood, plastic, or metal. Wooden sofa legs typically possess a certain aesthetic appeal and natural texture, can be matched with various sofa styles, and have relatively mature processing techniques and controllable costs. Plastic sofa legs, on the other hand, are widely used due to their lightweight, ease of molding, and low cost. They can be manufactured in various shapes and colors through processes such as injection molding to meet different design needs. However, existing technologies have the following problems:

[0003] The existing sofa legs lack cushioning components. When external forces are applied to the sofa, such as when a person sits down and stands up, the impact is directly transmitted to the sofa's support structure. This can easily cause the support structure to bear large instantaneous stress, potentially leading to loosening, deformation, or even damage at the connection points. Over time, this reduces the sofa's structural stability and reliability, shortening its lifespan. Furthermore, the existing system lacks casters and lifting mechanisms, making it very difficult to move the sofa. This causes significant inconvenience when users need to rearrange room layouts or adjust furniture positions to meet new needs (such as replacing new appliances or changing interior decoration styles). Additionally, the lack of a convenient movement mechanism makes cleaning the bottom of the sofa a challenging problem. Dust, hair, and other debris easily accumulate at the bottom, and prolonged neglect can negatively impact indoor hygiene and air quality. Utility Model Content

[0004] This invention provides a sofa leg with a cushioning structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A sofa leg with a cushioning structure includes a sofa body. Hollow support legs are fixedly connected to the four bottom corners of the sofa body. Two sofa cushions are provided on the top of the sofa body. Dampers are fixedly connected to the inner top walls of the four hollow support legs. Liftable sofa legs are fixedly connected to the bottom of the four dampers. The outer walls of the liftable sofa legs are slidably connected to the inner walls of the hollow support legs. Foot pads are fixedly connected to the bottom of the four liftable sofa legs. Cushioning components are provided on the left and right sides of the bottom of the sofa body. A universal wheel lifting component is provided in the middle of the bottom end of the sofa body.

[0007] A further improvement of this utility model is that: the bottom of each of the four foot pads is fixedly connected with an anti-slip pad, and the bottom of each of the four anti-slip pads is provided with a number of raised strips that are equidistantly distributed from left to right.

A connecting rod one is rotatably connected to the front top of the connecting plate, and a connecting rod two is rotatably connected to the rear top of the connecting plate. The connecting rod one and the connecting rod two are arranged crosswise.

[0009] A further improvement of this utility model is that: a sliding rod is fixedly connected to the opposite surfaces of the front and rear side plates, and sliders are slidably connected to both the front and rear sides of the outer wall of the sliding rod; a spring sleeved on the outer wall of the sliding rod is fixedly connected to the opposite surfaces of the front and rear sliders; the end of the connecting rod one away from the connecting plate is rotatably connected to the rear slider; the end of the connecting rod two away from the connecting plate is rotatably connected to the front slider; and the middle parts of the connecting rod one and the connecting rod two are rotatably connected.

[0010] A further improvement of this utility model is that: the universal wheel lifting assembly includes a fixed top plate, the top of which is fixedly connected to the top center of the sofa body; telescopic rods are fixedly connected to the four bottom corners of the fixed top plate; a fixed base plate is fixedly connected to the bottom of the four telescopic rods; a cylinder is fixedly connected to the bottom center of the fixed top plate; the output end of the cylinder is fixedly connected to the top center of the fixed base plate; casters are fixedly connected to the four bottom corners of the fixed base plate; and all four casters are universal wheels.

[0020] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0021] like Figure 1-3As shown, this utility model provides a sofa leg with a cushioning structure, including a sofa body 10. Hollow support legs 11 are fixedly connected to the four corners of the bottom of the sofa body 10. Two sofa cushions 12 are provided on the top of the sofa body 10. Dampers 15 are fixedly connected to the inner top walls of the four hollow support legs 11. Lifting sofa legs 13 are fixedly connected to the bottom of the four dampers 15. The outer walls of the lifting sofa legs 13 are slidably connected to the inner walls of the hollow support legs 11. Foot pads 14 are fixedly connected to the bottom of the four lifting sofa legs 13. Cushioning components 2 are provided on the left and right sides of the bottom of the sofa body 10. A universal wheel lifting component 3 is provided in the middle of the bottom end of the sofa body 10.

[0022] like Figure 1-3 As shown, anti-slip pads 16 are fixedly connected to the bottom of each of the four foot pads 14, and several raised strips are provided on the bottom of each of the four anti-slip pads 16.

[0023] Hollow support legs 11 are fixedly connected to the four corners of the bottom of the sofa body 10. The hollow support legs 11 are hollow columnar structures that provide installation space for internal components. Two sofa cushions 12 are provided on the top of the sofa body 10. The sofa cushions 12 can be made of high-resilience sponge material to provide users with a comfortable sitting experience. Anti-slip pads 16 are fixedly connected to the bottom of the four foot pads 14 through a vulcanization process. Several equidistant ridges are evenly distributed on the bottom of the anti-slip pads 16. These ridges can effectively increase the friction with the ground and prevent the sofa from sliding easily during use.

[0024] When the sofa body 10 is subjected to a vertical external force impact, such as the pressure generated by a person sitting on the sofa or a heavy object placed on the sofa, the damper 15 inside the hollow support leg 11 starts to work. The damper 15 will limit the rapid movement of the lifting sofa leg 13 inside the hollow support leg 11 through its own internal hydraulic or mechanical structure according to the magnitude and direction of the impact force, converting the impact energy into heat energy or other forms of energy for dissipation, thereby reducing the overall vibration amplitude of the sofa, preventing the sofa from swaying or displacing excessively due to sudden force, providing stable support for the user and reducing discomfort. The outer wall of the lifting sofa leg 13 and the inner wall of the hollow support leg 11 are slidably connected through a precision slide rail structure to ensure a smooth and stable lifting process.

[0025] like Figure 4As shown, the buffer assembly 2 includes two side plates 20. The tops of the front and rear side plates 20 are fixedly connected to the bottom of the sofa body 10. Rectangular grooves 24 are provided on the opposite surfaces of the front and rear hollow support legs 11. Connecting plates 25 are fixedly connected to the tops of the opposite surfaces of the front and rear lifting sofa legs 13. The outer walls of the connecting plates 25 are slidably connected to the inner walls of the front and rear rectangular grooves 24 respectively. Connecting rod 1 26 is rotatably connected to the front top of the connecting plate 25, and connecting rod 27 is rotatably connected to the rear top of the connecting plate 25. Connecting rod 1 26 and connecting rod 27 are arranged crosswise.

[0026] like Figure 4 As shown, a sliding rod 21 is fixedly connected to the opposite surfaces of the front and rear side plates 20. Sliding blocks 23 are slidably connected to both the front and rear sides of the outer wall of the sliding rod 21. A spring 22 sleeved on the outer wall of the sliding rod 21 is fixedly connected to the opposite surfaces of the front and rear sliding blocks 23. The end of the connecting rod 1 26 away from the connecting plate 25 is rotatably connected to the rear sliding block 23. The end of the connecting rod 27 away from the connecting plate 25 is rotatably connected to the front sliding block 23. The middle parts of the connecting rod 1 26 and the connecting rod 27 are rotatably connected.

[0027] Simultaneously, the buffer components 2 located on the left and right sides of the bottom of the sofa body 10 also work in coordination. Due to the sliding of the lifting sofa legs 13, the connecting plate 25 on its side will slide upward in the rectangular groove 24 of the hollow support leg 11. The connecting rod 1 26 and connecting rod 27 at the top of the connecting plate 25 will rotate with the movement of the connecting plate 25. Because connecting rod 1 26 is rotatably connected to the rear slider 23 and connecting rod 27 is rotatably connected to the front slider 23, and connecting rod 1 26 and connecting rod 27 cross and are rotatably connected in the middle, they will push the front and rear sliders 23 to slide in opposite directions on the slide rod 21 and stretch the spring 22. The spring 22 is stretched During the process, it absorbs and stores energy, converting external impact into the elastic potential energy of the spring, further buffering the impact force on the sofa and making the sofa's descent process more stable. Through the synergistic effect of the buffer component 2 and the damper 15, the impact force can be effectively absorbed and dispersed, preventing the sofa from vibrating or shaking due to sudden force, making the sofa's response more stable and gentle, preventing damage to the sofa's bottom structure due to large impacts, and extending the sofa's service life. At the same time, this buffering effect can also reduce the reaction force transmitted to the user's body due to the impact, reduce the risk of injury to the user's joints and muscles, and improve the overall user experience.

[0028] like Figure 5As shown, the universal wheel lifting assembly 3 includes a fixed top plate 30, the top of which is fixedly connected to the top center of the sofa body 10. Telescopic rods 31 are fixedly connected to the four bottom corners of the fixed top plate 30. A fixed base plate 33 is fixedly connected to the bottom of the four telescopic rods 31. A cylinder 32 is fixedly connected to the bottom center of the fixed top plate 30. The output end of the cylinder 32 is fixedly connected to the top center of the fixed base plate 33. Casters 34 are fixedly connected to the four bottom corners of the fixed base plate 33. All four casters 34 are universal wheels.

[0029] When the sofa needs to be moved, cylinder 32 is activated, and the piston of cylinder 32 extends, pushing the fixed base plate 33 downward along the telescopic rod 31. This causes the casters 34 at the bottom of the fixed base plate 33 to contact the ground and gradually lift the sofa body 10. At this time, the lifting sofa legs 13 and foot pads 14 are lifted off the ground, and the sofa can be easily moved by the rolling of the casters 34. When the sofa does not need to be moved, the piston of cylinder 32 retracts, the fixed base plate 33 rises, the casters 34 are lifted off the ground, and the sofa is supported again by the lifting sofa legs 13 and foot pads 14, maintaining a stable placement. With the universal wheel lifting assembly 3, the sofa can be easily lifted and moved to the desired position. This design eliminates the need for strenuous lifting or dragging of the sofa, greatly saving physical strength and time. When cleaning the house, the sofa can be easily moved to clean the dust and debris at the bottom. At the same time, when it is necessary to rearrange the room or adjust the furniture position, the movable sofa can adapt to new needs.

[0030] The working principle of this sofa leg with a cushioning structure will be explained in detail below.

[0031] like Figure 1-5 As shown, when the sofa body 10 is impacted by a vertical external force, such as the pressure generated by a person sitting on the sofa or a heavy object placed on the sofa, the damper 15 inside the hollow support leg 11 starts to work. The damper 15 will limit the rapid movement of the lifting sofa leg 13 inside the hollow support leg 11 through its internal hydraulic or mechanical structure according to the magnitude and direction of the impact force, converting the impact energy into heat energy or other forms of energy for dissipation, thereby reducing the overall vibration amplitude of the sofa, preventing the sofa from swaying or displacing excessively due to sudden force, providing stable support for the user and reducing discomfort. The outer wall of the lifting sofa leg 13 and the inner wall of the hollow support leg 11 are slidably connected through a precision slide rail structure to ensure a smooth and stable lifting process.

[0032] Simultaneously, the buffer components 2 located on the left and right sides of the bottom of the sofa body 10 also work in coordination. Due to the sliding of the lifting sofa legs 13, the connecting plate 25 on its side will slide upward in the rectangular groove 24 of the hollow support leg 11. The connecting rod 1 26 and connecting rod 27 at the top of the connecting plate 25 will rotate with the movement of the connecting plate 25. Because connecting rod 1 26 is rotatably connected to the rear slider 23 and connecting rod 27 is rotatably connected to the front slider 23, and connecting rod 1 26 and connecting rod 27 cross and are rotatably connected in the middle, they will push the front and rear sliders 23 to slide in opposite directions on the slide rod 21 and stretch the spring 22. The spring 22 is stretched During the process, it absorbs and stores energy, converting external impact into the elastic potential energy of the spring, further buffering the impact force on the sofa and making the sofa's descent process more stable. Through the synergistic effect of the buffer component 2 and the damper 15, the impact force can be effectively absorbed and dispersed, preventing the sofa from vibrating or shaking due to sudden force, making the sofa's response more stable and gentle, preventing damage to the sofa's bottom structure due to large impacts, and extending the sofa's service life. At the same time, this buffering effect can also reduce the reaction force transmitted to the user's body due to the impact, reduce the risk of injury to the user's joints and muscles, and improve the overall user experience.

[0033] When the sofa needs to be moved, cylinder 32 is activated, and the piston of cylinder 32 extends, pushing the fixed base plate 33 downward along the telescopic rod 31. This causes the casters 34 at the bottom of the fixed base plate 33 to contact the ground and gradually lift the sofa body 10. At this time, the lifting sofa legs 13 and foot pads 14 are lifted off the ground, and the sofa can be easily moved by the rolling of the casters 34. When the sofa does not need to be moved, the piston of cylinder 32 retracts, the fixed base plate 33 rises, the casters 34 are lifted off the ground, and the sofa is supported again by the lifting sofa legs 13 and foot pads 14, maintaining a stable placement. With the universal wheel lifting assembly 3, the sofa can be easily lifted and moved to the desired position. This design eliminates the need for strenuous lifting or dragging of the sofa, greatly saving physical strength and time. When cleaning the house, the sofa can be easily moved to clean the dust and debris at the bottom. At the same time, when it is necessary to rearrange the room or adjust the furniture position, the movable sofa can adapt to new needs.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
