Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically to a highly comfortable sofa with integrated seat and backrest. Background Technology

[0002] A sofa is a multi-seat chair with cushions, a backrest made of springs or thick foam, and armrests on both sides. It is a type of soft furniture. Sofas can be classified by function into functional sofas, fixed-back sofas, infinitely adjustable sofas, pneumatic sofas, electric sofas, and sofas with built-in TVs, etc. When the backrest rises or falls, the person's position on the seat cushion changes. For example, when the backrest falls, the person moves their buttocks backward, and vice versa. The rise and fall of the sofa backrest can be controlled by buttons on the buttons. When a person is sitting, the backrest of the sofa not only rises, but two pillows can also be raised in the waist and head areas to support the head and waist, which makes it much more comfortable. When the backrest falls flat, the person can lie down and rest. The backrest is flat, and only the headrest is there.

[0003] While existing electric sofas can be unfolded and have a backrest and front support, people of different heights have different needs. Therefore, when the electric sofa is unfolded, taller users' feet are dangling in the air, and the fixed size of the front support cannot be adapted to users of different heights. As a result, the comfort of existing electric sofas needs to be improved. Utility Model Content

[0004] This utility model provides a highly comfortable seat-back linkage sofa, which has the beneficial effect of high comfort and solves the problem mentioned in the background art that it cannot adapt to users of different heights, thus causing existing electric sofas to have insufficient comfort.

[0008] A support component is mounted on one end of a sliding board, the upper surface of which is flush with the upper surface of a sofa footstool, and the sliding board is used to support the human foot.

[0009] An airbag is mounted on the upper end of a support component and is used to support the human ankle.

[0010] As an optional solution for the highly comfortable seat-back linkage sofa described in this utility model, it further includes:

[0011] A through groove is provided at one end of the slide plate, and a base plate is slidably connected inside the through groove. The lower end of the support component is installed on the upper surface of the base plate.

[0012] A spring, one end of which is connected to the lower end of the base plate, and the other end of which is connected to the inner wall of the slide plate.

[0013] As an optional solution for the highly comfortable seat-back linkage sofa of this utility model, the supporting component includes a bracket and fabric;

[0014] The bracket is installed on the upper surface of the base plate;

[0015] The fabric covers the outer surface of the support frame, and the space between the fabric and the support frame is filled with sponge for supporting the human foot.

[0016] As an optional solution for the highly comfortable seat-back linkage sofa of this utility model, the lower end of the sofa footstool is equipped with an electric push rod for pushing the sliding plate, and one end of the electric push rod is connected to the other end of the sliding plate.

[0017] As an optional solution for the highly comfortable seat-back linkage sofa described in this utility model, the supporting component further includes a pressure relief valve and a button;

[0018] The pressure relief valve and button are located at the upper end of the fabric, between the airbag and the fabric, with the pressure relief valve above the button and the lower end of the pressure relief valve abutting against the upper surface of the button.

[0019] The button is electrically connected to the electric push rod.

[0020] As an optional solution for the highly comfortable seat-back linkage sofa of this utility model, one end of the fabric is provided with a first arc surface, and one end of the sofa footstool is also provided with a second arc surface, wherein the first arc surface is used to abut against the second arc surface.

[0022] This utility model has the following beneficial effects:

[0023] 1. This highly comfortable seat-back linkage sofa moves the support components via a sliding plate. When the support components rest against the user's feet, the sliding plate stops moving, and the support components support the user's feet. By adjusting the extension length of the support components to match the user's leg length, it can accommodate users of different heights.

[0024] 2. This highly comfortable seat-back linkage sofa adapts to users of different heights through a sliding skateboard. As the skateboard slides, it also drives the support components and airbags to slide, so the airbags can accurately support the user's ankles.

[0025] 3. This highly comfortable seat-back linkage sofa uses a pressure relief valve and a return spring to push the piston rod away from the button. At this time, the button sends a power-off signal to the electric push rod, which stops the electric push rod from pushing the sliding plate. This achieves automatic adaptation to different user heights, thereby improving the overall comfort of the sofa. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1-2 One type of highly comfortable sofa with integrated seat and backrest includes:

[0034] Sofa footstool 1;

[0035] The skateboard 3 is slidably connected to the lower end of the sofa footstool 1, and the extension distance of one end of the skateboard 3 is equal to the length of the human foot.

[0036] Support component 4 is installed at one end of the slide plate 3. The upper surface of the support component 4 is flush with the upper surface of the sofa footstool 1. The slide plate 3 is used to support the human feet.

[0037] Airbag 5 is installed on the upper end of support component 4 and is used to support the human ankle.

[0038] While existing electric sofas can be unfolded and have a backrest and front support, people of different heights have different needs. Therefore, when the electric sofa is unfolded, taller users' feet are dangling in the air, and the fixed size of the front support cannot be adapted to users of different heights. This results in the problem that the comfort of existing electric sofas needs to be improved.

[0039] The other end of the sofa footstool 1 is equipped with a hinge 2, and the sofa footstool 1 is installed on one side of the sofa through the hinge 2;

[0040] Preferably, hinge 2 is selected as a hinge;

[0041] according to Figure 1 As shown, the sofa footstool 1 is connected to the front of the sofa seat cushion via the hinge 2. Then, the electric hardware frame of the sofa is connected to the lower end of the sofa footstool 1, so that the sofa footstool 1 can rotate when the electric hardware frame is unfolded.

[0042] After the sofa footstool 1 has rotated, slide the slide plate 3 to one end so that the slide plate 3 is pulled out from the bottom of the sofa footstool 1. The slide plate 3 drives the support component 4 to move. When the support component 4 passes the human foot, stop pulling the slide plate 3. At this time, the support component 4 supports the human foot. By adjusting the extension length of the support component 4 to match the human leg length, it can be adapted to users of different heights.

[0043] Furthermore, since when a person leans back on a sofa, they generally support their feet with their heels, resulting in the ankles being suspended in the air, which would cause low comfort for the user, an airbag 5 is installed at the upper end of the support component 4 to support the user's ankles. The airbag 5 is filled with air, so it is highly malleable and can be adapted to a wide range of people.

[0044] It should be noted that the sliding skateboard 3 is adapted to users of different heights. When the skateboard 3 slides, it will drive the support component 4 and the airbag 5 to slide, so the airbag 5 can accurately support the user's ankle.

[0045] A through groove is provided at one end of the slide plate 3. The bottom plate 7 is slidably connected inside the through groove, and the lower end of the support component 4 is installed on the upper surface of the bottom plate 7.

[0046] Spring 8, one end of spring 8 is connected to the lower end of base plate 7, and the other end of spring 8 is connected to the inner wall of slide plate 3.

[0047] When the sofa footstool 1 is not unfolded, its support component 4 is retracted at the lower end of the slide plate 3, and the upper end surface of the support component 4 abuts against the lower end surface of the sofa footstool 1.

[0048] according to Figure 2 As shown, when the sofa footstool 1 is unfolded, the sliding plate 3 drives the support component 4 to slide to one end. When the upper surface of the support component 4 is no longer in contact with the lower surface of the sofa footstool 1, the spring 8 pushes the base plate 7 and the support component 4 to slide upward, so that the upper surface of the support component 4 is flush with the upper surface of the sofa footstool 1, thereby enabling the support component 4 to better support the user's feet.

[0049] Support component 4 includes bracket 41 and fabric 42;

[0050] The bracket 41 is installed on the upper surface of the base plate 7;

[0051] Fabric 42 covers the outer surface of support 41, and sponge for supporting human feet is filled between fabric 42 and support 41.

[0052] Example 2

[0053] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 1-4 The lower end of the sofa footstool 1 is equipped with an electric push rod 6 that pushes the skateboard 3 to slide, and one end of the electric push rod 6 is connected to the other end of the skateboard 3;

[0054] Support component 4 also includes a pressure relief valve 44 and a button 43;

[0055] The pressure relief valve 44 and the button 43 are located at the upper end of the fabric 42. The pressure relief valve 44 and the button 43 are located between the airbag 5 and the fabric 42, and the pressure relief valve 44 is located above the button 43. The lower end of the pressure relief valve 44 is used to abut against the upper surface of the button 43.

[0056] Button 43 is electrically connected to electric push rod 6;

[0057] The pressure relief valve 44 includes a piston groove, a piston rod, and a return spring. The piston groove is located at the upper end of the fabric 42, and the piston rod is slidably connected inside the piston groove. The piston rod and the fabric 42 are connected by a return spring.

[0058] The piston rod is used to abut against the upper surface of button 43;

[0059] One end of the fabric 42 is provided with a first arc surface 9, and one end of the sofa footstool 1 is also provided with a second arc surface 10. The first arc surface 9 is used to abut against the second arc surface 10.

[0060] according to Figure 3 and Figure 4As shown, the electric push rod 6 pushes the slide plate 3 to one end. When the upper end of the support component 4 is no longer in contact with the lower end of the sofa footstool 1, the spring 8 pushes the base plate 7 and the support component 4 to slide upward, so that the upper end of the support component 4 is flush with the upper end of the sofa footstool 1. At this time, the airbag 5 on the upper end of the support component 4 will be in contact with the user's calf. The airbag 5 is in a compressed state. At this time, the pressure relief valve 44 is squeezed downward by the high pressure air of the airbag 5 and slides against 45. In this way, the electric push rod 6 is transmitted to the electric push rod 6 through 45, so that the electric push rod 6 continues to push the slide plate 3 to one end.

[0061] When the airbag 5 moves to the user's ankle, the air pressure inside the airbag 5 will decrease because the ankle is suspended in the air. This will push the piston rod away from the button 43 through the return spring of the pressure relief valve 44. At this time, the button 43 sends an electrical signal to the electric push rod 6 to stop the electric push rod 6 from pushing the slide plate 3 to slide. This achieves automatic adaptation to different user heights, thereby improving the overall comfort of the sofa.

[0062] It should be noted that when the electric push rod 6 is reset, the electric push rod 6 pulls the first arc surface 9 to abut against the second arc surface 10, thereby squeezing the support component 4 downward through the second arc surface 10, so that the upper end of the support component 4 retracts to the lower end of the sofa footstool 1.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0064] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
