As described in the patent literature, many sofas have a thick backrest and are splendid. On the other hand, the backrest may be made of a thin plate from the viewpoint of weight reduction and space saving. In addition, considering the development of variations, it is conceivable to make it an assembly type so that it is possible to select whether or not to attach a backrest or the like.

When multiple thin plate-shaped backrests are retrofitted, it is practically difficult to manufacture the backrests with exactly the same dimensions and shape, so their upper ends may not be aligned. When the backrest is thick as in Patent Documents 2 and 3, it is not so noticeable even if it is displaced by several millimeters, but in the case of a thin plate-shaped backrest, the disorder of arrangement can be recognized with the naked eye even with an error of several millimeters, and the product quality. (See Fig. 13, the discrepancy in the backrest can be recognized). As mentioned above, it is difficult to completely eliminate the manufacturing error of the backrest, and increasing the machining accuracy leads to an increase in cost.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a sofa capable of improving the aesthetic appearance by arranging a plurality of backrest portions in an arrangement while facilitating variation development.

The present invention relates to a sofa in which a plurality of backrest portions having a back region in contact with the back of one person are arranged on a seat portion having a seating surface area for seating for a plurality of people.
Each of the plurality of backrest portions has a plate shape and is divided into a back surface area and a mounting area that intersect each other.
Each of the plurality of backrest portions is fixed to the seat portion at the portion of the mounting region and is erected, and the ends of the back surface region are arranged so as to be substantially aligned.
It is characterized in that the side surfaces of two adjacent back surface regions are connected to each other by a connecting member.

Constrictions are provided at the same positions on the opposite edges of the two adjacent back regions, and an opening is formed by the constrictions in the arranged state.
The connecting member may be configured to connect the side surfaces of the adjacent backrest portions by sandwiching the periphery of the opening from the front surface and the back surface.

An armrest portion that is plate-shaped and is divided into a back surface region and a mounting region that intersect each other is erected on a portion of the edge of the seat surface region where the backrest portion is not provided. You may.

Further, a seat cushion placed on the seat surface region of the seat portion and a back cushion placed on the back surface region of the backrest portion are provided.
The back cushion is provided with a band-shaped member, and the band-shaped member may be configured to be sandwiched between the seat cushion and the backrest portion.

According to the present invention, since the side surfaces of the two adjacent back regions are connected to each other by a connecting member, the arrangement of the plurality of backrest portions can be aligned to improve the aesthetic appearance.

FIG. 10 is a cross-sectional view taken along the line CC of FIG. The figure showing the back of the back cushion (photo), the connecting member is not attached. The figure (photograph) showing the attached state of the backrest cushion, the connecting member is not attached. It is sectional drawing (hidden line display) which shows the attachment state of the backrest cushion.

An embodiment of the invention will be described with reference to the drawings.

1 to 6 are views showing the sofa. The cushion of the sofa is removable, and FIGS. 1 to 3 show a state in which the cushion is placed or attached, and FIGS. 4 to 6 show a state in which the cushion is removed. 1 to 3 are the same as FIGS. 4 to 6 except for the presence or absence of a cushion. Although FIGS. 1 to 6 show a high-back sofa for three people, the sofa can be applied to a sofa for one person or two people (see FIG. 7).

As shown in FIGS. 1 to 6, the sofa has a seat portion 1 having a seating surface area for seating for a plurality of people, and a plurality of (three) backrest portions 2 having a back area in contact with the backs of each person. , The armrest portion 3 is provided. The backrest portion 2 and the armrest portion 3 can be selected at the time of assembly, and if necessary, a part or all of the backrest portion 2 and the armrest portion 3 can be prevented from being attached (see FIG. 7).

A frame 11 composed of two square pipes is attached to the lower surface (back surface) of the seat portion 1. Two short square pipes intersecting at about 90 degrees are connected to both ends of the two square pipes. Legs 4 are attached to the ends of the short square pipes.

A seat cushion C1 is placed on the seat portion 1, and a backrest cushion C2 and an armrest cushion C3 are placed on the front side of the backrest portion 2 and the armrest portion 3 (FIGS. 1 to 3).

The backrest portion 2 is divided into a back surface region (long portion) 2a and a mounting region (short portion) 2b by bending a plate-shaped member such as plywood by about 90 degrees (about 80 degrees in the example of the figure). Will be created. In other words, the back surface area 2a and the mounting area 2b are created so as to intersect each other. The backrest portion 2 is fixed to and erected on the seat portion 1 at the portion of the mounting region 2b (see FIG. 5, reference numeral 12 indicates a mounting hole). The three backrest portions 2 are arranged so that the upper ends of their back surface regions 2a are substantially aligned (see the plan view and the front view of FIG. 5).

FIG. 7 is an explanatory diagram of the variation development of the sofa. The seat 1 is prepared as a small one for one person, a medium one for two people, and a large one for three people. The same applies to the seat cushion C1. An arbitrary number of backrest portions 2 and armrest portions 3 can be attached to each seat portion 1. No backrest, no elbows, no armrests, no cushions and a part of the seat 1 is table-shaped, with one elbow, one elbow with one armrest, table-shaped with armrests There are variations such as a couch with one elbow and an armrest with no backrest attached to one side. It can also encourage social distance by not attaching a backrest in the middle.

The backrest 2 of the sofa is made of wood made by bending plywood for weight reduction, but it is also made of synthetic resin made of resin as a molded product or made of metal made by bending a metal plate. It is also possible. Since the backrest portion 2 has a curved plate shape, some distortion may occur in any of the manufacturing methods, and the angles may not be aligned on the left and right sides thereof. For this reason, in general, simply attaching the backrest portion 2 to the seat portion 1 does not make the upper ends of the backrest portion 2 line up in a substantially straight line. Disordered arrangement may spoil the aesthetics.

In order to eliminate the disorder of the arrangement, in the present sofa, the backrest portions 2 adjacent to each other by the connecting member 5, specifically, the facing side surfaces of the back surface region 2a are connected so as to sandwich the surfaces without looseness. The connecting member 5 itself is also configured so as not to play. Even if there is a slight discrepancy between the side surfaces of the adjacent back surface region 2a, the connecting member 5 corrects the difference by sandwiching the side surface of the back surface region 2a.

The connecting member 5 will be described with reference to FIGS. 8 to 12.
The connecting member 5 is composed of, for example, a synthetic resin connecting member front surface portion 51 and a connecting member back surface portion 52 made of a resin as a molded product (see FIG. 8). The connecting member front surface portion 51 includes a set screw or bolt through hole 51a (not shown), a protrusion portion 51b that engages with the connecting member back surface portion 52, and a front flange portion 51c that presses the backrest portion 2 at a portion wider than the protrusion portion 51b. To prepare for. The back surface portion 52 of the connecting member includes a set screw or bolt through hole 52a (not shown), a recess 52b for receiving the protrusion 51b of the front surface portion 51 of the connecting member, and a constricted portion engaging portion 52d that engages with the constricted portion 21 of the backrest portion 2. It is provided with a back flange portion 52c that is wider than the constricted portion engaging portion 52d and presses the backrest portion 2 at that portion. The side surface of the adjacent back region 2a is sandwiched between the front flange portion 51c and the back flange portion 52c (see FIGS. 10 and 11).

A constricted portion 21 is provided at the edge of the back surface region 2a of the backrest portion 2 (see the upper view of FIG. 9). The constricted portions 21 are all provided at the same position. An opening (through hole) H is formed by the constricted portions 21 of the two adjacent back surface regions 2a in a state where the backrest portions 2 are attached and arranged. The connecting member 5 is fitted into this opening H (see the lower view of FIG. 9). As a result, the backrest portions 2 are connected to each other, and the three backrest portions 2 are arranged in a substantially straight line (see the plan view of FIG. 5 and FIG. 11).

The outer circumference of the constricted portion engaging portion 52d corresponds to the shape of the opening H formed by the constricted portion 21 of the back surface region 2a (see FIG. 12). The back surface portion 52 of the connecting member is inserted into the opening H from the back surface, the front surface portion 51 of the connecting member is inserted from the front surface, and the protrusion 51b is fitted into the recess 52b of the back surface portion 52 of the connecting member (see FIG. 11). The connecting member 5 sandwiches the backrest portion 2 by inserting a set screw or a bolt (not shown) into the through holes 51a and 52a and tightening the holes.

According to the above configuration, the connecting member 5 has an adjacent backrest by sandwiching the periphery of the opening H formed by the constricted portion 21 of the back surface region 2a from the front surface by the connecting member front surface portion 51 and from the back surface by the connecting member back surface portion 52. The side surfaces of the portions 2 are connected to each other so that the backrest portions 2 are lined up in a substantially straight line.

All the cushions on the sofa are removable. The backrest cushion C2 is provided with a member for avoiding an unintentional dropout. A description will be added with reference to FIGS. 13 to 15.

A band-shaped member 6 is attached to the backrest cushion C2 (see FIG. 13). The strip-shaped member 6 is made of cloth, for example. The tip portion 61 is thicker than the portion of the band-shaped member 6. The tip portion 61 is sandwiched between the backrest portion 2 and the seat cushion C1 (see FIGS. 14 and 15), and the backrest cushion C2 is difficult to come off.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, it is.
