Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a movable headrest structure of a zero-wall-attached sofa. Background Art

[0002] A sofa is a multi-seat chair equipped with cushions, a backrest chair equipped with springs or thick foam plastics, etc., with armrests on both sides and a headrest on the top. It is a kind of soft furniture. The existing zero-wall-attached sofa refers to a sofa design that can be placed closely against the wall without gaps when placed. This design can save more space in a limited space, especially suitable for small-sized residential houses. The zero-wall-attached sofa usually has special treatments in terms of structure, such as an internal spring hinge function, so that the sofa can smoothly approach or leave the wall when unfolded or folded up. Such a design not only optimizes space utilization but also may provide a more flexible and comfortable sitting and lying experience.

[0003] After retrieval, the patent No. CN212853023U discloses a headrest structure for a sofa, including a sofa body. A height adjustment mechanism is connected to the top of the sofa body, and a headrest is connected to the top of the height adjustment mechanism. The height adjustment mechanism includes a fixed column, a connecting rod, a movable disc, a partition board, a return spring, a connecting plate, a positioning pin, a positioning ball and a positioning groove. The other side of the positioning ball penetrates through a hole opened on the side surface of the movable disc and is inserted into the positioning groove opened on the inner wall of the fixed column. By slightly rotating the headrest to separate the positioning ball from the positioning groove, pulling up or pressing down the headrest can adjust the height of the headrest, which is convenient for people of different heights to use. After the adjustment is completed, rotating the headrest in the reverse direction to insert the positioning ball into the positioning groove at the corresponding position can position the height of the headrest, increasing the comfort of using the headrest.

[0004] However, in the above scheme, the adjustment effect of the headrest structure is not ideal. Its disadvantages are as follows: the inclination angle of the headrest is inconvenient to adjust, and it is difficult to further bend and adjust so that the headrest can contact the user's back neck, resulting in a great reduction in the comfort of the sofa.

[0005] Therefore, a movable headrest structure of a zero-wall-attached sofa is proposed, which has the advantages of convenient adjustment of the headrest inclination angle and increased comfort, thereby solving the problems in the above background art. Summary of the Utility Model

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] According to an embodiment of the utility model, a movable headrest structure of a zero-wall sofa is provided.

[0022] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figures 1-3As shown in the figure, the movable headrest structure of the zero-wall sofa according to the embodiment of the present utility model includes a sofa body 1. A trapezoidal groove 5 is formed at the top of the sofa body 1, and a base 7 is fixed in the trapezoidal groove 5 by bolts. Two arc-shaped rods 6 are welded to the top surface of the base 7, and a support block 8 is arranged between the two arc-shaped rods 6. Connecting sleeves 9 sleeved with the two arc-shaped rods 6 are respectively welded to both ends of the support block 8, and a first plum blossom knob 10 abutted against the arc-shaped rod 6 is screwed on the outer surface of the connecting sleeve 9. A soft headrest 2 is arranged above the sofa body 1, and a telescopic leather sleeve 3 is sewn between the soft headrest 2 and the sofa body 1. A rotating shell 4 is fixedly connected to the bottom of the soft headrest 2, and a rotating column 11 is installed in the cylindrical cavity of the rotating shell 4. A second plum blossom knob 12 is screwed at both ends of the rotating shell 4, and a rubber disc 14 is bonded to one end of the second plum blossom knob 12, and the rubber disc 14 of the second plum blossom knob 12 abuts against the end face of the rotating column 11. A connecting column 16 is welded to the bottom of the rotating shell 4, and the bottom of the connecting column 16 is fixedly connected to the top surface of the support block 8 by screws. Among them, the height of the connecting column 16 is suitable for the soft headrest 2 to tilt to the left or right. In order to facilitate the operation of the first plum blossom knob 10, a zipper is sewn on the cover of the sofa body 1, which is convenient to penetrate into the trapezoidal groove 5, and the second plum blossom knob 12 can be directly rotated and adjusted through the telescopic leather sleeve 3;

[0023] In one embodiment, two anti-slip pads 15 are bonded in the cylindrical cavity of the rotating shell 4, and both anti-slip pads 15 are in contact with the outer surface of the rotating column 11. The anti-slip pads 15 arranged on the inner wall surface of the rotating shell 4 are in close contact with the outer surface of the rotating column 11, maintaining the tight connection between the rotating shell 4 and the rotating column 11 and increasing the friction between the two, so as to maintain the stability of the soft headrest 2 in any inclined angle state.

[0024] In one embodiment, the telescopic leather sleeve 3 is integrally rectangular in structure, and a plurality of pleated parts in the shape of rectangular frames are equidistantly arranged on the surface of the telescopic leather sleeve 3. Through the setting of the telescopic leather sleeve 3, the gap between the soft headrest 2 and the sofa body 1 can be filled, and it is easy to adaptively "telescope" during the inclination adjustment stage of the soft headrest 2, with good aesthetics.

[0025] In one embodiment, a vertical surface is arranged on the left side wall of the sofa body 1, and a slope surface is arranged on the right side wall of the sofa body 1, and the vertical surface of the sofa body 1 faces the wall. In the present utility model, the sofa body 1 is specifically a zero-wall sofa. A zero-wall sofa refers to a sofa design that can be placed close to the wall without leaving a gap when placed. This design can make the sofa save more space in a limited space, especially suitable for small-sized houses. There are mature products, so no further explanation is made on its structure and principle.

[0026] In one embodiment, the upper end surfaces of the two arc rods 6 of the base 7 are welded with limiting disks 13. The limiting disks 13 can limit the connection sleeve 9 to prevent the connection sleeve 9 from detaching from the arc rods 6.

[0027] In one embodiment, the support block 8 is composed of a steel rectangular frame and a scissor-shaped connecting rod welded inside the frame. This structure is helpful to reduce the material used in the support block 8, increase the lightness, and save costs.

[0028] Working principle:

[0029] When in use, firstly, the vertical surface of the sofa body 1 is pressed against the wall to meet the installation requirements of the zero-wall sofa. When the inclination angle of the headrest needs to be adjusted, the soft-packed headrest 2 is moved in the left and right directions to cause the rotating shell 4 at the bottom of the soft-packed headrest 2 to rotate about the rotating column 11 inside it, and the soft-packed headrest 2 is tilted to the left or right according to the bending direction of the soft-packed headrest 2. The second plum blossom knobs 12 arranged at both ends of the rotating shell 4 can maintain the stability of the soft-packed headrest 2 in any inclination state. The anti-slip pad 15 arranged on the inner wall of the rotating shell 4 is in close contact with the outer surface of the rotating column 11 to keep the rotating shell 4 and the rotating column 11 stable. The tightness of the connection of the rotating column 11 increases the friction between the two. On this basis, by pulling the soft-packed headrest 2, the support block 8 fixed below the soft-packed headrest 2 is prompted to move on the surface of the arc rod 6 through the connecting sleeve 9, so that the soft-packed headrest 2 can rotate with the center of the circle corresponding to the arc rod 6 as the origin. Combined with the first plum blossom knob 10 screwed on the surface of the connecting sleeve 9 and the arc rod 6, it is easy to maintain the overall stability of the soft-packed headrest 2 after rotation adjustment, so as to achieve the effect of the soft-packed headrest 2 contacting the back of the user's neck, while facilitating the adjustment of the inclination angle of the soft-packed headrest 2 and improving the comfort.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
