Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a multifunctional sofa. Background Art

[0002] The sofa is a common piece of furniture, usually placed in places such as the living room, providing people with a comfortable place to rest and sit. The design of sofas is becoming more and more diverse, with simple modern style, European classical style, Chinese style, etc., which can meet the aesthetic needs and home decoration styles of different people. It is not only a practical piece of furniture, but also an indispensable part of family life, adding a warm and comfortable atmosphere to the home space.

[0003] When a user wants to lie flat on the sofa to sleep, the sofa backboard is designed to take up a certain space, and the sofa seat is usually limited in width to facilitate the user to bend his knees. Therefore, the sofa provides limited space for lying flat when the user wants to sleep on the sofa. For this reason, we propose a multifunctional sofa. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a multifunctional sofa.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows: a multifunctional sofa includes a base and also includes:

[0006] Two armrest plates, the two armrest plates are fixedly connected to the left and right end surfaces of the base respectively;

[0007] An L-shaped seat plate, wherein the lower end surface of the L-shaped seat plate is fixedly connected to two sliders, the upper end surface of the base is carved with a receiving groove, the lower inner wall of the receiving groove is fixedly connected to two slide rails, and the two sliders are slidably connected to the two slide rails respectively;

[0008] The back plate has circular grooves on both left and right end surfaces of the back plate, and rotating rods are fixedly connected in the two circular grooves. The circumferential surfaces of the two rotating rods are fixedly connected to limiting rods. The rear parts of the adjacent end surfaces of the two armrest plates are fixedly connected to circular tubes, and the adjacent end surfaces of the two circular tubes are carved with notches. The two rotating rods are respectively rotatably connected in the two circular tubes, and the two limiting rods are respectively movably connected in the two notches.

[0009] Preferably, two second rollers are fixedly connected to the front portion of the lower end surface of the L-shaped seat plate.

[0010] Preferably, two first rollers are fixedly connected to the rear portion of the lower end surface of the L-shaped seat plate, and the two first rollers are respectively rollingly connected to the lower inner wall of the accommodating groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this solution, the rotation of the back panel and the forward and backward translation of the L-shaped seat panel cooperate with each other to provide the user with a larger lying space when he needs to lie down to sleep, and the user can lean on the back panel when sitting to rest. This product is simple and convenient to operate and extremely practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] like Figure 1-Figure 4 The multifunctional sofa shown includes a base 1 and further includes:

[0020] Two armrest plates 2, the two armrest plates 2 are fixedly connected to the left and right end surfaces of the base 1 respectively;

[0021] An L-shaped seat plate 8 is fixedly connected to the lower end surface of the L-shaped seat plate 8 with two sliders 5. The upper end surface of the base 1 is carved with a receiving groove 3. The lower inner wall of the receiving groove 3 is fixedly connected to two slide rails 4. The two sliders 5 are slidably connected to the two slide rails 4 respectively.

[0022] The back plate 9 has circular grooves 10 on both left and right end surfaces of the back plate 9, and rotating rods 14 are fixedly connected in the two circular grooves 10. The circumferential surfaces of the two rotating rods 14 are fixedly connected to limit rods 13. The rear parts of the adjacent end surfaces of the two armrest plates 2 are fixedly connected to circular tubes 11, and the adjacent end surfaces of the two circular tubes 11 are carved with notches 12. The two rotating rods 14 are respectively rotatably connected in the two circular tubes 11, and the two limit rods 13 are respectively movably connected in the two notches 12.

[0023] During operation, when it is necessary to lie down and sleep on this device, the L-shaped seat plate 8 is pulled forward, and the L-shaped seat plate 8 drives the slider 5 to slide in the slide rail 4. Since the front end surface of the back plate 9 is no longer blocked by the L-shaped seat plate 8, the back plate 9 is rotated so that the front end surface of the back plate 9 is in contact with the upper end surface of the base 1. The rotation of the back plate 9 drives the rotating rod 14 to rotate, and the rotation of the rotating rod 14 drives the limiting rod 13 to move in the notch 12 until the back plate 9 and the base 1 are completely in contact with each other. Then, the L-shaped seat plate 8 is moved backward so that the rear end surface of the L-shaped seat plate 8 is in contact with the back plate 9. At this time, the upper end surfaces of the L-shaped seat plate 8 and the back plate 9 are in the same plane, and the user can lie on the L-shaped seat plate 8 and the back plate 9 to sleep.

[0024] In this solution, the rotation of the back panel 9 cooperates with the front and rear translation of the L-shaped seat panel 8 to provide the user with a larger lying space when lying flat to sleep, and the user can lean on the back panel 9 when sitting to rest. This product is simple and convenient to operate and extremely practical.

[0025] Specifically, two second rollers 7 are fixedly connected to the front portion of the lower end surface of the L-shaped seat plate 8 .

[0026] During operation, by setting two second rollers 7, the second rollers 7 can roll on the ground when the L-shaped seat plate 8 moves forward and backward, thereby reducing the friction between the L-shaped seat plate 8 and the ground, and facilitating the push-pull movement of the L-shaped seat plate 8.

[0027] Specifically, two first rollers 6 are fixedly connected to the rear portion of the lower end surface of the L-shaped seat plate 8 , and the two first rollers 6 are respectively rollingly connected to the lower inner wall of the accommodating groove 3 .

[0028] During operation, the two first rollers 6 are provided to reduce the friction between the slider 5 and the slide rail 4 and the L-shaped seat plate 8 and the base 1 , thereby further facilitating the push-pull movement of the L-shaped seat plate 8 .

[0029] Working principle of this utility model:

[0030] When it is necessary to lie down and sleep on this device, the L-shaped seat plate 8 is pulled forward, and the L-shaped seat plate 8 drives the slider 5 to slide in the slide rail 4. Since the front end surface of the back plate 9 is no longer blocked by the L-shaped seat plate 8, the back plate 9 is rotated so that the front end surface of the back plate 9 is in contact with the upper end surface of the base 1. The rotation of the back plate 9 drives the rotating rod 14 to rotate, and the rotation of the rotating rod 14 drives the limiting rod 13 to move in the notch 12 until the back plate 9 and the base 1 are completely in contact with each other. Then, the L-shaped seat plate 8 is moved backward so that the rear end surface of the L-shaped seat plate 8 is in contact with the back plate 9. At this time, the upper end surfaces of the L-shaped seat plate 8 and the back plate 9 are in the same plane, and the user can lie on the L-shaped seat plate 8 and the back plate 9 to sleep.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention as claimed, and the scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
