Description

How to change the sofa {VERIFYING METHOD OF SOFA}

The present invention relates to a sofa, and more particularly, to a multi-variable sofa that can freely and conveniently deform the overall design of the sofa and increase space utilization, and to a method of changing the sofa.

In general, the sofa (Sofa) is largely composed of a back portion and a seat portion. At this time, the backrest part is composed of a backrest frame and a backrest cushion as a configuration for supporting the user's back, and the seat part is composed of a seat frame and a seat cushion as a configuration for supporting the user's buttocks (lower body). In addition, separate from this, the sofa may further include armrests on both sides depending on the type.

These sofas are classified in a variety of lengths and shapes, and are divided into single, double, or 3,4 seat sofas according to their length, and are used by being divided into ordinary sofas or couch sofas according to their shape.

In particular, the couch sofa has a structure in which the functions of a sofa and a bed are combined, and it is a structure in which a seat sofa and a bed sofa are combined, and the bed sofa is formed in a separate type and can be selectively assembled on the left or right side of the seat sofa. Shape, etc.

However, since the above-described conventional sofa or couch sofa cannot be transformed with each other, a general sofa or couch sofa must be selected and purchased according to a sofa installation space or consumer preference at the time of initial purchase. Therefore, in the case of changing to a regular sofa or a couch sofa, it has to be repurchased, and thus there is an inefficient and inefficient problem.

In order to solve this problem, a variable type couch sofa is disclosed. This is a single sofa with a backrest, a sofa for two, and a square sofa for one without a back, respectively, and the sofas for 1 and 2 and the square sofas are arranged in a row to become a long sofa for 3 or 4 people. , After arranging the sofas for 1 and 2 persons in a row, the square sofas were arranged in the front so that they could be used in a variable form to become a couch sofa.

However, since the above-described variable sofa sofa is divided into a single sofa, a double sofa, and a square sofa for one without a backrest, there is a disadvantage that the overall aesthetic is deteriorated if the sofas are not arranged neatly by moving each sofa.

In particular, since the three sofas must be moved and rearranged as a whole in order to change the flexible couch sofa, there is a disadvantage in that it is not easy to use the entire variable in the case of a powerless user such as children or the elderly, and thus improvement measures are required.

In particular, when it is not transformed into a couch sofa and is not used, there is also a need for improvement measures to increase space utilization by minimizing space restrictions.

The above-described technical configuration is a background technology for aiding understanding of the present invention, and does not mean a conventional technology widely known in the art to which the present invention belongs.
