Description

Sofa cover improved structure

The present invention relates to a sofa cover, and more particularly to an improved structure of a sofa cover.

Conventional sofas, because of various types, there are many kinds of sofa covers that are used to cover the outside of the sofa to change the appearance or cover the damaged surface, but the main structure completely needs to compare the actual size. Customized to cover; also use a large piece of cloth, can also be implemented with the pressure bar; but these structures are designed with the special or non-specific design of the sofa, which is not a good application concept, but also affects It is inconvenient to replace the user, because the learner is mainly not easy to get rid of it; in order to provide more suitable items, the creator conducts research and development to solve the problems that are easy to use in the conventional use.

In order to provide an item that is more in line with actual needs, the creator conducts research and development to solve the problems that are easy to use in the conventional use.

The main purpose of this creation is to provide a modified structure of the sofa cover, which is a general-purpose structure, which basically meets the needs of most sofas, and only needs to be changed in size, and can be pre-quantized for production, cost and price. They are all Lido. The most important thing is that the car system is easier, and the user's detachment is more convenient, so that users can change the color and material at any time, just like the function of a bed cover.

In order to achieve the above objectives, the structure of the creation is: one main piece and two side pieces, which can be applied to sofas of various types of single seat, the main piece has a wide section and a narrow section, and the main piece has a wide section length. The height of the back of the sofa is increased by the height of the front back and is formed by the width of the sofa. The length of the main piece is the depth of the sofa cushion plus the height of the seat cushion, and the width difference of the wide section is a quarter arc on both sides; the side piece is composed of Seat depth plus sofa back thickness to form side panel depth, armrest width plus armrest height plus seat cushion height Forming a side panel height, a side angle between the side panel depth and the side panel height to form an arc corresponding to the aforementioned quarter arc; the main segment narrow section cushion height on both sides of the corresponding outer side panel height bottom point up the seam After that, the remaining side panel heights are folded in half, and the main panel wide section back height is reduced from the front side height of the corresponding inner side panel height bottom point to the upper seam, and then the main section wide section is left to the folding car Sew and align the side panels and the side panel depth to the corresponding main piece arc and the remaining part of the narrow section of the main piece.

In order to enable your review committee to further understand the techniques, means and functions of this creation for the purpose of achieving the intended purpose, a better and feasible embodiment is presented, and the detailed description of the drawings is followed, and the purpose and characteristics of the creation are believed. And the advantages, when you can get a deep and specific understanding.
