JP 2006-187534 A

  By the way, for example, when such a chair is installed in a waiting room of a hospital, an appropriate seating depth varies depending on a medical subject, a patient's disease, and the like. However, since chairs having a conventional configuration such as that described in Patent Document 1 cannot change the seating depth of the seat, when such chairs are installed in the waiting room of a hospital, the seats having different shapes are used. It is necessary to install chairs having different seating depths at necessary locations. In other words, it is necessary to prepare a plurality of types of chairs in advance and to arrange a chair having a seat having a shape corresponding to each necessary portion. Moreover, not only in the waiting room of a hospital, but also in the case where such a chair is installed in a place where it is necessary to install a chair having a different seating depth depending on the use and the nature of the space, Even when a chair where only a name can be seated is installed, such effort is similarly required.

  Therefore, the present invention focuses on the above-described problems, and an object thereof is to reduce the labor described above by realizing a seating depth of a plurality of types of seats with a common component configuration.

  That is, in order to solve the problems as described above, a chair according to the present invention includes a chair body and a first mounting posture in which one edge is located in front of the chair body or a second edge in which the other edge is located in front. A seat that is detachably mounted by selecting one of the mounting postures, and the relative position in the front-rear direction differs between the first mounting posture and the second mounting posture between the chair body and the seat. A positioning mechanism for positioning the seat with respect to the chair body is provided.

  If it is such, since the relative position in the front-rear direction of the seat with respect to the chair main body is different between the state in which the seat is mounted in the first mounting posture and the state in which the seat is mounted in the second mounting posture, The seating depth can be changed by changing the mounting posture of the seat while using the seat.

  In order to realize the effect described in the previous stage with a simple configuration, the chair body is provided with a column standing on the front side of the seat receiving portion, and the positioning mechanism includes the column, the seat, When the seat is mounted on the seat receiving portion in the first mounting posture, the depth of the first recess is different from that of the first recess. It is desirable to have a second recess that is formed on the other edge of the seat and fits into the column later when the seat is mounted on the seat receiving portion in the second mounting posture. If it is such, since the depth of the said 1st recessed part or the 2nd recessed part differs, the relative position with respect to the chair main body of a seat is set by fitting either of these 1st recessed parts or a 2nd recessed part to a pillar. This is because it can be changed.

  Further, a plurality of persons can be seated in parallel on the seat, and each seated person sits between the pillars or between the pillars and the side edge of the chair body. If it is a thing, the function which partitions the seating space for one person can also be provided to this pillar.

  In particular, if the pillar supports the armrest member, the appearance can be made similar to a lobby chair having a normal armrest, so that the seating depth can be changed while keeping the appearance natural.

  In order to solve the above-described problem with a simple configuration, the seat can be provided at a position displaced inward by a first predetermined distance from the other edge, and can hit the back surface of the seat receiving portion. A first standing wall, and a second standing wall provided at a position displaced inward from the one edge by a second predetermined distance different from the first predetermined distance and capable of striking against a back surface of the seat receiving portion. It is preferable that the positioning mechanism includes an upright wall, and the positioning mechanism includes the seat receiving portion, the first upright wall, and the second upright wall. In such a case, since the first predetermined distance and the second predetermined distance are different, the orientation of the seat is changed, and either the first standing wall or the second standing wall is received by the seat. This is because the relative position of the seat with respect to the chair body can be changed by striking against the back of the section.

  According to the present invention, the seat relative to the chair main body is changed by selecting either the first mounting posture or the second mounting posture as the mounting posture of the seat on the chair main body, The seating depth can be changed. That is, while preparing a chair body and a seat having the same shape, the seating depth can be changed only by changing the mounting posture of the seat. Accordingly, a plurality of types of chairs having seats with different seating depths are prepared. Without using, a chair with an appropriate seating depth can be installed at each location while using a common chair body and seat.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The chair 1 according to the present embodiment is mainly installed in a waiting room of a hospital. FIG. 1 is an overall perspective view, FIG. 2 is an exploded perspective view, and FIG. 3 and FIG.
