  The present invention relates to an improved armchair removable sofa, and more particularly to an armchair removable sofa that can be attached and detached with a simple structure and can maintain the interior decoration of the sofa.

  As is well known, recently, sofas in which an armrest is made as a separate member from the sofa body and can be attached and detached according to the purpose of use are frequently used.

  Conventionally, with respect to such a sofa, a rail member is mounted on the side of the seat base of the sofa body, a hook member for the rail member is attached to the side surface of the armrest, and the hook member is placed on the rail member. There has been proposed a sofa having a structure in which an armrest is detachable by fixing with a fastening tool in a state (see, for example, Patent Document 1).

  However, the conventional sofa structure described above requires a coupling mechanism such as a rail member or a hooking member having a complicated form, which not only increases the manufacturing cost but also repairs the coupling mechanism when it fails. There were also dissatisfaction points for the user, such as having to ask a contractor to replace the parts.

  In addition, conventionally, a sofa having an L-shaped insertion fitting attached to the side surface of the armrest and a socket fitting for the insertion fitting attached to the side surface of the sofa body so that the armrest can be attached and detached. It is publicly known (see, for example, Patent Document 2).

However, in the conventional sofa, when the armrest is removed from the sofa body, the side fittings are exposed and the interior decoration of the sofa is extremely impaired.

In addition, since the sofa of the present invention can be made compact by removing the armrest, it is easy to carry and carry in and out of a small room, etc. Furthermore, when the sofa body and part of the armrest are dirty or damaged Furthermore, since it is very convenient that only the parts can be cleaned, repaired, or replaced, it can be said that the practical utility value is very high.

  The embodiment of the present invention will be described in more detail with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a sofa body, and what is indicated by reference numeral 2 is a bracket base. In the present embodiment, block-shaped wood is used so that the sofa body 1 can be supported gently at a predetermined height on the floor surface. Next, what is indicated by reference numeral 3 is an armrest, and what is indicated by reference numeral 4 is an engaging member.

  Next, the configuration of the embodiment will be described below. First, when the armrest 3 is not used, the bracket base 2 having insertion holes 21 a and 21 b at both ends is provided to the four corners of the lower surface of the sofa body 1, and the engaging member 4 that matches the diameter of the insertion hole 21 is provided. Use and fix (see FIGS. 1 and 2).

  At this time, for example, the locking hole 11a is screwed in the bottom plate of the sofa body 1, and a bolt member is used as the engaging member 4, and the bracket base 2 can be fixed by screwing to these. In the present embodiment, the sofa body 1 is provided with an inner locking hole 11b so that the bracket base 2 can be stably fixed to the locking hole 11a and the inner locking hole 11b when the armrest 3 is not used. In addition, the engaging member 4 used when the armrest is connected is accommodated in the inner locking hole 11b to prevent the engaging member 4 from being lost.

  And when using the armrest 3, after removing the engaging member 4 and taking out the bracket base 2 to the side, the bracket base 2 is engaged with one insertion hole 21a and the locking hole 11a. Then, the bracket base 2 is fixed in a state protruding from the sofa body 1 (see FIG. 3).

  Furthermore, after the bracket base 2 was taken out to the side, the portion protruding from the sofa body 1 of the bracket base 2 and the lower surface of the armrest 3 were connected, and the sofa body 1 and the armrest 3 were configured to be connectable ( (See FIGS. 4 and 5). As with the sofa body 1, the armrest 3 is also provided with a connecting hole 31 in the bottom plate, and the bracket base 2 can be fixed using the connecting hole 31 and the unused insertion hole 21b.

  By configuring as described above, the connecting mechanism of the armrest 3 can be made a simpler structure. Further, the interior decoration of the sofa can be maintained because the appearance of the sofa is not impaired by the bracket base 2 regardless of the presence or absence of the armrest 3.

  In the present embodiment, the groove 22 along the adjacent line between the sofa body 1 and the armrest 3 is provided in the upper part of the bracket base 2. As a result, it is possible to avoid a situation in which the edge of the sofa cover C is sandwiched between the bottom surface of the sofa body 1 or the armrest 3 and the bracket base 2 and the sofa is rattled or the cover is damaged.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of the “Practical model registration claims”. As long as the bracket base 2 has a certain hardness to support the sofa, the bracket base 2 may adopt a metal material or a synthetic resin material instead of wood, and the shape is not a block shape but a plate shape. It does not matter.

  In addition, a dowel-shaped bar material is used for the engaging member 4 instead of a bolt material, and fitting holes are formed in the bottom surfaces of the sofa body 1 and the armrest 3 so that the sofa body 1 and the armrest 3 and the bracket base 2 May be connected.

  Further, the number and arrangement of the locking holes 11a of the sofa body 1 and the connecting holes 31 of the armrest 3 may be changed as necessary, and both belong to the technical scope of the present invention.

  Recently, importance has been given to the flexibility of the sofa shape, and a sofa that can accommodate various designs and uses is desired by the user selecting an armrest having a different shape and function. However, the conventional armrest attachment / detachment structure is complicated and unsatisfactory for both manufacturers and users. In addition, there are many cases where the interior decoration of the sofa is impaired when the armrest is removed, and this is a fatal defect in view of the decorative values of the sofa at present.

  Under such circumstances, the armchair removable sofa of the present invention combines a simple armrest connection structure and excellent interior decoration, so there is no doubt that it is a sofa that can eliminate the above dissatisfaction, It can be said that the industrial utility value of the present invention is very high.
