However, in the former chair, the inclination angle of the backrest can be adjusted and fixed by attaching the backrest to a horizontal hole connected to the side of the sliding frame on which the seat is placed and fixed, so that it can freely appear and retract from the side of the frame. Fixation is achieved by engaging and releasing the knob from the side, but in this fixing method, the knob for fixing or releasing the seat plate is provided on the outside of the frame as a separate member from the seat. Therefore, when adjusting the inclination angle of the backrest, especially when the seat plate and backrest are wide, large, and heavy, such as a chaise longue, it is necessary to release the lock of the knob and hold the seat near the center. This required multiple operations, such as locking and fixing with the knob again after changing, which was time-consuming. In addition, since the knob as a locking member is a single movable member, its strength is relatively weak, and furthermore, when in use, external forces such as the weight of the seated person are Since a force is applied in the vertical direction, the engagement portion between the knob and the hole is likely to be damaged.

ら、座枠の移動は一層困難である。 In addition, in the latter chair, by lifting the front free end of the seat frame and moving the seat frame back and forth, the inclination angle of the back support frame connected to the seat frame with a hinge can be changed. Since the frame is mounted on the guide rod at the connection part with the back support frame at the rear end, it is difficult to move the seat frame forward and backward or move the back support frame smoothly, making it difficult to move the seat frame forward. When the seat frame is moved, the connecting part will float upward from the guide rod, and when the front free end of the seat frame is pushed and the seat frame is moved rearward, the rear end of the seat frame will slope downward. In some cases, it may become difficult to move the seat by hitting the guide rod of the seat.In particular, in the case of a chaise longue, the seat frame and back support frame are long and heavy, making it even more difficult to move the seat frame. be.

A locking rod 22 with a plurality of locking recesses 23 connected in the front and back direction is installed in the space as one of the locking members that locks by fitting the concave and convex portions. Stop rod 2
At a position corresponding to the second locking recess 23, there is a locking protrusion that can be fitted into the second locking recess 23 when the seat plate 3 is superimposed on the sliding plate 20 as the other locking member. The part 24 is protruded, and the seat plate 3 is connected to the sliding plate 20.
In the state in which the seat plate 3 is placed on top of one another, that is, in the use state in which the seat plate 3 is in the seated position, the locking recess 23 and the locking protrusion 24 engage with each other in a concave-convex manner, so that the seat plate 3 moves in the front-rear direction. The inclination angle of the backrest 4 is also fixed. To change the inclination angle of the backrest 4 from this state, lift the front end of the seat plate 3 upwards and rotate it around the rear end hinged to the sliding plate 20 to engage it as a locking member. By releasing the engagement between the locking recess 23 of the locking rod 22 and the locking convex portion 24 on the lower surface of the seat plate 3, the seat plate 3 can be slid in the front-rear direction, and in this state, the seat plate 3 can be moved back and forth. If force is applied to move the seat plate 3 back and forth, the lower end position of the backrest 4 will move in accordance with the movement of the seat plate 3, and the inclination angle of the backrest 4 will change. When the backrest 4 reaches the desired inclination angle, the seat plate 3 is rotated downward and placed on the sliding plate 20 again, and the locking convex portion 24 on the lower surface of the seat plate 3 is locked. Original locking recess 2 in rod 22
The position of the seat plate 3 and the inclination angle of the backrest 4 are fixed by fitting and locking the seat plate 3 again into the locking recess 23 at a position shifted by the amount of movement of the seat plate 3 from the position of the seat plate 3.

ないのである。 As mentioned above, according to the chair 1 according to the present invention,
The locking recess 23 of the locking rod 22 and the lower surface of the seat plate 3 serve as engagement members that regulate the movement of the seat plate 3 in the front-rear direction with an extremely simple operation of lifting the front part of the seat plate 3 upward. The inclination angle of the backrest 4 can be adjusted by simply moving the seat plate 3 back and forth. Not only can the inclination angle be easily adjusted, but especially in the case of a chaise longue as in the above embodiment, the operation can be performed by holding any part of the seat plate 3, and the operation can be performed to release the lock of the seat plate 3. By simultaneously performing the operations of moving the position of the seat plate 3 and adjusting the inclination angle of the backrest 4, not only is the inclination angle adjustment operation extremely easy, but also the locking rod 2 acts as a locking member.
Since the direction of the fitting and locking between the locking recess 23 and the locking protrusion 24 of 2 is the same as the direction of the load applied to the seat plate 3 due to the weight of the person sitting on the chair 1, a strong fitted state is achieved. As a result, the seat plate 3 can be securely fixed without the risk of the seat plate 3 becoming unlatched and moving during use, and the locking rod 22 and the locking protrusion 24 as locking members are respectively attached to the bottom plate. 13 and the seat plate 3, the strength is high and there is little risk of damage.
