Description

Technical Field

[0001] The utility model relates to an improvement of a household furniture product, in particular to an improvement of a sofa. Background Art

[0002] Sofas have become essential furniture for many families and offices. There are generally three types of sofas sold on the market: low-back sofas, high-back sofas, and ordinary sofas between the first two. Sofas are widely welcomed by people as a tool for rest and relaxation.

[0003] The most important thing about a sofa is the elasticity of the lower part of the seat cushion, which is generally achieved through springs, bandages or fillers. Spring sofas are prone to fatigue, breakage and damage after long-term use, especially under the support of heavy objects, which will greatly shorten the service life of spring sofas; and the elastic bandages used in bandage sofas are very easy to loosen and break. After a period of use, the elastic effect of bandage sofas will be greatly reduced and appear loose and lose elasticity, which will bring a very poor user experience. Stuffed sofas also have many problems due to the fillers themselves, such as poor elasticity, easy deterioration, and easy insects. Utility Model Content

[0004] The purpose of the utility model is to provide a sofa with self-adjusting softness and hardness in view of the defects and shortcomings of the prior art. The sofa has the advantages of long service life, good elasticity and directionality, and can bring good user experience to users. It does not have the risk of spring fatigue, breakage, and damage of spring sofas, nor the risk of looseness and breakage of bandage sofas. There is no risk of inferior filling.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: it includes a sofa seat 1, a plurality of frame bars 2 are arranged in the sofa seat 1, a plurality of connecting seats 3 are evenly arranged on the frame bars 2, and an elastic seat 4 is plugged into each connecting seat 3; the elastic seat 4 is composed of an upper panel 5, two sockets 6, and a plug-in seat 7, the two sockets 6 are cross-arranged and fixed on the bottom surface of the upper panel 5, and the plug-in seat 7 is arranged between the two sockets 6 and plugged into the hole groove of the socket 6.

[0006] Both ends of the upper panel 5 are arc-shaped, four plug holes 51 are evenly distributed in the middle of the upper panel 5, a snap buckle 52 is provided on one side of the lower surface of the upper panel 5 close to the plug holes 51, and arc hole grooves 53 are respectively provided at both ends of the upper panel 5.

[0007] The outer side of the plug hole 51 is provided with four expansion holes 54 , and the expansion holes 54 are provided with expansion heads 55 extending downward.

[0008] The socket 6 includes a socket base 61, two support beams 62, and two connecting columns 63. The base 61, the support beam 62, and the connecting columns 63 are an integrated structure. The two connecting columns 63 are arranged on both sides of the bottom of the base 61. The support beam 62 is composed of two arc-shaped support plates 621. The top of the support beam 62 is provided with a socket fixing hole 622.

[0009] The sleeve connector 6 is divided into an upper sleeve connector 6A and a lower sleeve connector 6B. A groove 9 is provided in the middle of the upper sleeve connector 6A and is stacked with the lower sleeve connector 6B.

[0010] The socket 7 includes an intermediate connector 71, and four circular plug-in columns 72 are arranged on the periphery of the intermediate connector 71. The circular plug-in columns 72 are connected to the intermediate connector 71 through a connecting piece 73; a plug-in slot 711 is arranged in the intermediate connector 71, and the plug-in slot 711 matches the connector 3. When in use, the socket 7 is arranged between two sockets 6, and the four circular plug-in columns 72 of the socket 7 are respectively inserted into the socket fixing holes 622 of the two sockets 6 to be fixed.

[0011] The connecting seat 3 is fixed on the frame cross bar 2 by fixing screws 31. The connection is fixed by fixing screws 31, which is convenient for adjusting the position and can also be replaced in time and conveniently after the connecting seat 3 is damaged.

[0012] The bottom surface of the sofa seat 1 is provided with an observation window 11, which is closed by a zipper 12 and fixed on the bottom surface 13 of the sofa seat 1. The observation window 11 can facilitate users to understand the internal structure when purchasing, let users understand the internal structure and material, and increase user trust; at the same time, adding the observation window 11 can also facilitate users to understand the use of the interior of the sofa, and when a component is damaged, the damage can be timely understood.

[0013] The working principle of the utility model: in actual use, after the two sockets 6 are stacked, the four connecting columns 63 are inserted into the plug-in holes 51 of the upper panel 5, and the sockets 6 are fixed and connected by the snap buckles 52; the socket 7 is arranged between the two sockets 6, and the four circular plug-in columns 72 of the socket 7 are respectively inserted into the socket fixing holes 622 of the two sockets 6 to form fixation; the mechanism formed in this way can bend and swing downward when different points on the upper surface of the upper panel 5 are stressed, forming elastic contraction and swing back. When a person sits on the sofa, multiple upper panels 5 will be stressed to tilt and elastically contract, thereby forming a good elastic effect. Due to the contraction and upward swing at multiple points, the overall deformation is more in line with the ergonomic characteristics, allowing users to have a better use experience.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are as follows: it eliminates the spring and bandage, has the advantages of long service life, good elasticity and directionality, can bring users a good user experience and also prolong the service life; there is no risk of spring fatigue, breakage, and damage of spring sofas, nor the risk of looseness and breakage of bandage sofas; there is no risk of inferior fillings; even if the middle connecting seat 3 and elastic seat 4 are damaged, it only needs to simply and quickly replace the corresponding connecting seat 3 and elastic seat 4 to restore the overall effect, and it will not collapse due to weakened elasticity like spring sofas and bandage sofas due to long-term use, and replacement is also very troublesome. The overall use effect is good, the service life is long, and maintenance is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
