Description

  The present invention is an improvement of an assembly-type sofa, more specifically, it is possible to increase design variations by combining parts, and the sofa form can be changed according to how to relax, and the carrying-in work can be easily performed. The present invention relates to a sofa structure that can be assembled and reconfigured.

  As is well known, sofas are often installed in the room as furniture to relax, and the types of single sofas can be changed to multi-seats with multiple seats. There are various types such as a corner sofa placed in the corner.

  However, the size of the sofa is basically large even if it is a single sofa. Therefore, when purchasing a sofa, you must first consider whether it is a size that can be carried into the room. The sofa that can be purchased may be limited depending on the shape of the passage and whether or not it can be lifted and loaded.

  Also, even if the sofa is the size that can be carried in, it is necessary to move the sofa while turning it sideways or tilting it while changing the angle. It took a lot of time and effort to carry in, because it was necessary to take care not to damage it.

  On the other hand, because sofas have a strong interior aspect, it is desirable to have as many design types as possible. However, conventional integrated sofas have problems in manufacturing costs and inventory management, so the number of variations must be limited. It was. Also, it was difficult to attach and detach the cover, and it was not easy to use.

  Therefore, in the past, in order to solve the above problems, the backrest, armrest, seat cushion, etc. should be parts that can be attached to and detached from the sofa base, and these parts can be assembled at the installation location to obtain a finished product. Assembling-type sofas have been proposed and already known (see, for example, Patent Documents 1 and 2).

  However, since the conventional assembly type sofa has a uniform position for attaching the backrest and the armrest, there is only one pattern of the completed sofa. For example, the arrangement of the armrest and the backrest of the multi-sofa is changed to sleep. It was not possible to give the sofa a degree of freedom, such as a chair.
