Description of the Related Art As a so-called stacking mode in which chairs are superimposed on each other for storage, there are a horizontal stack in which the chairs are approached from the front and back, and a vertical stack in which the chairs are approached from the top and bottom. Of these, the horizontal stack is generally configured to be retracted to a position where it does not interfere with the seats of other chairs by raising the seats, so there is a different mechanism such as a locking mechanism between the legs and the seats. In a chair provided with the above mechanism, the weight of the mechanical portion easily interferes with the writhing function of the seat, and the stacking state is generally realized by a vertical stack which does not generally require the writhing of the seat.

態になる。In such a configuration, when the user sits on the seat and leans on the back, the back leans backward against the elastic body according to the load. Along with this, a seat pivotally supported at the front end by the leg and supported at the back by the rear induces a turning operation rearward and downward about the pivot point. As a result, the whole chair is in a state where the occupant takes a comfortable posture. On the other hand, when the occupant removes the load on the back, the elastic body emits a repulsive force, which urges the back to rotate forward, and conversely, the seat rotates around the pivot point. Then, a pivoting operation is caused to move forward and upward, and the whole chair is brought into a state where the occupant takes a normal posture.

ることが可能になる。As described above, the chair of the present invention utilizes the structure in which the seat is supported on the front end by the leg and swingably supported on the rear end by the back. The locking function can be imparted to the entire chair simply by adding a configuration that introduces an elastic body that accumulates a repulsive force by utilizing the backward tilt, while slightly devising the connecting structure of the chair. For this reason, the weight is greatly reduced as compared with the case where a locking mechanism is separately formed, bulkiness around the seat does not occur, and a smooth operation and high stack pitch at the time of stacking can be realized.

め、ロッキング機構部等との両立が容易となる。The present invention is embodied in the form described above and has the following effects. In other words, the chair of the present invention allows the seat to move on the legs in the front-rear direction.
Supported and swingable to the back via link member
Press and supported, the rear end of the seat is from I Ri lower surface side to the front edge to the upper surface of the seat of another chair entering from the rear during horizontal stack
And it is one that is configured to be lifted to a position where it does not interfere with the seat of the other chair I'm in it are raised. For this reason, even when the weight of the entire chair is increased, the work efficiency relating to the stacking work is greatly improved, and the restriction on the number of stacks can be eliminated. In addition, compared with the conventional horizontal stack, the amount of movement of the seat is kept to the minimum necessary, so that compatibility with the locking mechanism and the like can be easily achieved.

を実現することが可能になる。In the case where the seat is supported by the leg at the front end so as to be movable in the front-rear direction and the rear end is swingably supported by the back via the link member, the space below the seat can be easily formed. When opened, the front edge of the chair seat located at the rear can be guided without difficulty into the lower surface of the seat located at the front.
In this case, using a structure in which the seat is supported at the front end by the leg and swingably connected at the rear end to the back, while slightly devising the connection structure between the base end of the back and the leg, By using an elastic body that accumulates repulsive force by using the back of the back, it is possible to demonstrate the locking function of the entire chair, compared to the case where the locking mechanism is separately configured. Significant weight reduction can be achieved, bulkiness around the seat does not occur, and smooth operation during stacking and high stack pitch can be realized.
