Technical Field

[0001] The utility model relates to the technical field of sofas, and particularly relates to a sofa capable of storing items. Background Art

[0002] A sofa capable of storing items is a design that combines furniture and storage functions, aiming to maximize the use of space. This type of sofa is more suitable for small-sized apartments. By means of the storage function, household items can be stored, occupying less indoor space. Such sofas usually have hidden storage spaces where items such as quilts, clothes, and toys can be stored, helping to keep the home environment tidy. The storage function space of sofas capable of storing items mostly adopts drawer, push-pull, flip, and rotation function designs.

[0003] For a sofa capable of storing items designed with a push-pull mechanism, most of the storage space is extended under the seat cushion. When in use, the seat cushion is manually moved to expose the storage space. However, sofas capable of storing items come in various sizes, including four-person or three-person sofas in a row. When using a larger-sized sofa capable of storing items, it is very laborious to pull the seat cushion, especially inconvenient for women with less strength. To solve this technical problem, the utility model proposes a sofa capable of storing items. Summary of the Utility Model

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a sofa capable of accommodating items includes a frame 1, a backrest 2 and a cushion 3. The backrest 2 is hinged to the frame 1. By the hinged connection between the backrest 2 and the frame 1, when it is necessary to convert the sofa into a temporary bed, by moving out the cushion 3 and then putting down the backrest 2 to be flush with the cushion 3, it can be used as a temporary bed. The cushion 3 is arranged above the frame 1. The inner bottom wall of the frame 1 is connected with a support frame 4. The inner side of the support frame 4 is rotatably connected with a first lead screw 5. One side of the support frame 4 is provided with a motor 6. The output shaft of the motor 6 is connected with one end of the lead screw. The lower surface of the cushion 3 is connected with a threaded seat 7. The inner side of the threaded seat 7 is threadedly connected with the outer surface of the lead screw. The support frame 4 provides a supporting force for the first lead screw 5. Taking the motor 6 as the power, after the motor 6 rotates, it drives the first lead screw 5 to rotate. The cushion 3 receives the power through the threaded seat 7. After the lead screw rotates, it pushes the threaded seat 7 to move, and the threaded seat 7 drives the cushion 3 to move.

[0024] Two rollers 8 are installed on the lower surface of the cushion 3. The two rollers 8 are symmetrical. When the cushion 3 moves outwards, through the contact between the rollers 8 and the ground, it is convenient for the cushion 3 to move.

[0025] Two threaded sleeves 9 are connected to the lower surface of the cushion 3. The inner walls of the two threaded sleeves 9 are both threadedly connected with a second lead screw 10. One end of the second lead screw 10 located outside the threaded sleeve 9 is rotatably connected with a bottom plate 11. The outer surface of the second lead screw 10 is connected with a force - adding disc 12. The threaded sleeve 9 supports the second lead screw 10 to make the second lead screw 10 stable. Through the position movement generated by rotating the second lead screw 10, it can perform the function of supporting the cushion 3. The bottom plate 11 is in contact with the ground to facilitate the rotation of the second lead screw 10. The force - adding disc 12 increases the contact area with the hand to facilitate the rotation of the second lead screw 10. Through the support of the second lead screw 10 for the cushion 3, the force on the rollers 8 is reduced.

[0026] The outer surface of the frame 1 is connected with a support base 13. A third lead screw 14 is connected to the inner side of the support base 13 in a threaded manner. One end of the third lead screw 14 is rotatably connected with a top plate 15, and the other end of the third lead screw 14 is connected with a runner 16. The support base 13 supports the third lead screw 14 to make the lead screw have stability. The position is moved by the rotation of the lead screw to provide power for the movement of the top plate 15. Through the support of the top plate 15 on the backrest 2, the backrest 2 has an angle adjustment function to meet the needs of different people for the use angle of the sofa.

[0027] The inner wall of the frame 1 is connected with a storage rack 17, and the lower surface of the frame 1 is connected with a plurality of support legs 18. The plurality of support legs 18 are located at the four corners of the frame 1. The storage rack 17 is used to store small parts that are often needed, which is convenient for taking when in use. The frame 1 is supported by the support legs 18 to keep the frame 1 away from contact with the ground and prevent the sofa from being corroded by damp ground.

[0028] Electric heating wires 19 are installed inside both the seat cushion 3 and the backrest 2. The backrest 2 and the seat cushion 3 are heated by the electric heating wires 19. It is relatively cold in winter in the north. To improve the comfort of the sofa, the seat cushion 3 and the backrest 2 of the sofa are heated to make people sit more comfortably on it.

[0029] A storage bin 20 is opened inside the frame 1. A plurality of partition boards 21 are detachably connected to the inner wall of the storage bin 20, and the plurality of partition boards 21 are staggered with each other. The storage bin 20 is used to hold items. The storage bin 20 is divided into multiple areas by the partition boards 21. Different items are placed in the small spaces separated by the partition boards 21 to prevent various items from being mixed up and inconvenient to take when in use.

[0030] It should be noted that in actual use of this device, first start the motor 6 to rotate. After the motor 6 rotates, it drives the first lead screw 5 to rotate. After the first lead screw 5 rotates, it pushes the threaded seat 7 to move. The threaded seat 7 drives the seat cushion 3 to move. While the seat cushion 3 is moving, it pushes the roller 8 to rotate. The roller 8 supports in front of the seat cushion 3 to facilitate the movement of the seat cushion 3. Subsequently, the items to be stored are placed inside the storage bin 20, and then the motor 6 is started to rotate in the reverse direction to retract the seat cushion 3.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
