Description

Technical Field

[0001] The invention relates to the technical field of modular furniture, in particular to a multifunctional modular wear-resistant sofa. Background Art

[0002] The origin of sofas can be traced back to ancient Egypt around 2000 BC, but the real soft-covered sofa appeared in the late 16th century and early 17th century. At that time, sofas were mainly filled with natural elastic materials such as horsehair, bird feathers, and plant fluff, and covered with fabrics such as velvet and embroidery to form a soft surface for human contact. For example, the Huaxingger chair, which was popular in Europe at that time and used by the public, was one of the earliest sofa chairs. With the advancement of technology, there are more and more types of sofas, such as functional sofas, fixed-back sofas, infinitely controlled sofas, pneumatic sofas, electric sofas, and sofas with TVs. However, the existing sofas are all used in a single way and cannot provide users with a variety of use effects. At the same time, the existing sofas have poor wear resistance. Once damaged, the service life of the sofa will be greatly reduced, which will seriously increase the user's use cost.

[0003] Patent application number CN201110115155.6 provides a kind of multifunctional combination furniture that combines sofa, coffee table and bed into one, which comprises a sofa, a movable bed assembled on the sofa and the coffee table; wherein:

[0004] The sofa comprises a base, a backrest, an armrest and a sofa cushion, the upper part of the base is provided with a plurality of first rails, the lower part of the base is provided with a storage cabinet with a storage function, the backrest is provided with a plurality of second rails, a third rail is provided on the top side of the backrest, and the armrest is provided with a storage cabinet with a storage function;

[0005] The movable bed comprises a sliding bottom plate, a sliding back plate, a hinge connecting the sliding bottom plate and the sliding back plate, and a supporting foot. The sliding bottom plate is provided with a plurality of first sliding grooves, and the sliding back plate is provided with a plurality of second sliding grooves. The first sliding grooves cooperate with the first guide rails, and the second sliding grooves cooperate with the second guide rails, so as to facilitate the opening or folding of the movable bed.

[0006] The coffee table comprises a coffee table surface, a coffee table cabinet, and a connecting part connected to a sofa backrest. One end of the coffee table surface is assembled on the coffee table cabinet, and the other end is assembled with the connecting part; wherein: the coffee table surface comprises a main panel, an auxiliary panel sliding with the main panel, a first folding panel assembled on one side of the main panel, and a second folding panel assembled on the first folding panel. One end of the first folding panel close to the coffee table cabinet is connected to the second folding panel by a hinge. A groove is provided at the bottom of the main panel, and the groove is used to assemble the auxiliary panel; the connecting part comprises a connecting body and a rolling mechanism, one end of the connecting part is connected to the main panel of the coffee table, and the other end is assembled with the third slide rail of the sofa backrest.

[0007] This technical solution combines the functions of a sofa, a coffee table and a bed into one. It has a novel structure and is easy to use during conversion, which increases practicality while reducing indoor space occupation. It is especially suitable for indoor use in small apartments and small apartments.

[0008] Although this technical solution increases the functions of the sofa and makes the sofa have multiple use effects, it is cumbersome to operate and has low use efficiency. Although it occupies a small space, the operation space when folding and expanding each structure is large. This device is not suitable for indoor use in small apartments and apartments with small indoor space. At the same time, each structural device in this technical solution does not improve its own wear resistance, so it cannot be used for a long time and cannot reduce the user's use cost.

[0009] The patent with application number CN201721773493.8 provides a highly wear-resistant sofa cover, including a cushion cover, a backrest cover and an armrest cover, wherein the cushion cover includes a cushion fabric body, the backrest cover includes a backrest fabric body, the armrest cover includes an armrest fabric body, the cushion fabric body, the backrest fabric body and the armrest fabric body are all cut and made of sofa fabric, the sofa fabric includes a base fabric layer, and the base fabric layer is interwoven into a plain weave by warp yarn and weft yarn. The upper surface of the base fabric layer is coated with a wear-resistant layer; the cushion cover also includes a cool mat cushion, which is fixed to the back of the cushion fabric body, and a wear-resistant fabric strip one is sewn on the back of the cushion fabric body, which protrudes from the back of the cushion fabric body, and the wear-resistant fabric strip one defines a seating area, and the cool mat cushion is covered and fixed on the seating area; the backrest cover also includes a cool mat cushion, which is fixed to the back of the backrest fabric body, and the backrest fabric body includes a front backrest and a back chair part, and a wear-resistant fabric strip two is sewn on the back of the front backrest, which protrudes from the back of the front backrest, and the wear-resistant fabric strip two defines a backrest area, and the cool mat cushion is covered and fixed on the backrest area; the armrest cover also includes a cool mat armrest pad, which is fixed to the back of the armrest fabric body, and a wear-resistant fabric strip three is sewn on the back of the armrest fabric body, which protrudes from the back of the armrest fabric body, and the wear-resistant fabric strip three defines an armrest area, and the cool mat armrest pad is covered and fixed on the armrest area.

[0010] The technical solution is that a sofa cover is sleeved on the outer side of the sofa, and the sofa cover can be used on both sides. In autumn and winter, the front side of the sofa cover is used with the wear-resistant layer of the sofa cover facing upwards, which can resist friction during use and has high wear resistance, and the front side of the sofa cover will not be easily worn out; in spring and summer, the back side of the sofa cover is used with the cool mat seat cushion, cool mat back cushion and cool mat armrest pad facing upwards, which is relatively cool. The direct contact between the user and the sofa fabric is reduced, thereby reducing the wear of the fabric of the sofa cover, thereby increasing the service life of the sofa cover, and when the back side is used, the wear-resistant layer of the sofa cover is in direct contact with the sofa, which also makes the sofa cover and the sofa wear-resistant.

[0011] Although this technical solution improves the wear resistance of the sofa, it has a relatively simple structure and is relatively single in use. It cannot provide users with an experience of multiple use effects and cannot be widely promoted.

[0012] In view of this, it is very necessary to invent a multifunctional combined wear-resistant sofa. Summary of the invention
