Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chair that can be compactly stored.

[0002]

[Prior art]

 When it is possible to store a chair in a narrow space, it is possible to fold and store the legs like a pipe folding chair, or to stack the fixed legs vertically. Stacking chairs and the like, which are configured in a shape and can be stacked one after another, are known.

As described above, the conventional chair has to be lifted up when it is stored. Therefore, if the pipe is made thick or the seat frame and the backrest are made thick, the chair becomes heavy and cannot be handled easily. . Therefore, in order to reduce the weight of conventional stacking chairs, a relatively thin pipe material with a diameter of about 13 mm is often used. For example, a relatively thick pipe material with a straight diameter of 22.2 mm or more is not used. Almost never used.

Therefore, the chair made of the relatively thin pipe material as described above is flexible as a whole as compared with the chair made of the thick pipe material, and lacks stable rigidity.

Further, among the chairs as described above, there are known chairs provided with a memo board, but it often becomes an obstacle when storing.

[0006]

[Problems to be solved]

 An object of the present invention is to provide a chair which is easy to handle even if it is made of a thick pipe material and can be compactly stored even if a memo board is provided.

[0007]

[Means for solving problems]

 According to the present invention, a seat frame frame having a seat frame that is widened forward and connected to the seat frame and a connecting rod that connects the rear side of the seat frame, and casters provided at the front and rear ends of the seat frame are provided. Front and rear legs, and a seat plate placed on the seat frame and hinged to the connecting rod so as to be reversible.The seat plate of the other chair is placed between the seat frames with the seat plate inverted. A chair characterized by being able to store a frame is provided, and the above object is achieved.

Further, according to the present invention, the front legs of the chair are formed in series through an armrest frame connecting the upper ends of the backrest frame portions formed above the rear legs, and the armrest frame is formed on the armrest frame. A chair is provided in which a memo board is rotatably attached to a standing memo board stand so as to be rotatable in the left-right direction and the front-rear direction, and the above object is achieved.

【Example】

 A description will be given below with examples. Referring to FIGS. 1 and 2, a seat frame frame (1) has seat frames (2) and (2) provided so as to be opposed to each other such that a facing space is widened from a rear side to a front side. The rear ends of the frames (2) and (2) are connected by a connecting rod (3). The front ends of the seat frames (2) and (2) are bent outward and extend, and the front ends thereof are fixed to the front legs (5) and (5) having the casters (4).

The rear ends of the seat frames (2) and (2) are fixed to rear legs (6) and (6) having casters (4). As shown in FIG. 2 (b), the rear legs (6) and (6) have a narrow interval between the fixed portions of the rear legs (6) and (6), which are fixed to the seat frames (2) and (2), and the spines extending above the rear legs. The sagging frame (7) and the lower facing interval are widened, respectively, but these intervals are formed to be narrower than the facing interval of the front legs. A backrest (8) is formed on the backrest frame (7) above the rear legs (6), (6).

The upper ends of the backrest frame portions (7) and (7) are fixed to the armrest frame (9), and the armrest frame (9) extends to both sides to extend the front legs (5) and (). It is formed in a series with 5).

The seat plate (10) is sized to be placed on the seat frames (2) and (2), and the rear end portion (11) is located between the seat frames (2) and (2). The width is narrower than the interval. On the back surface of the seat plate (10), a fastening plate (12) having a cross section of approximately Ω is attached so as to hold a part of the connecting rod (3). It is hinged to the connecting rod (3) so that it can be reversed. A stopper such as a screw (not shown) is provided on the connecting rod (3) so as to project to both sides of the fastening plate (12), or a protrusion is provided on the connecting rod in the circumferential direction of the fastening plate. A groove for engaging the protrusion is provided to prevent the seat plate from moving left and right (not shown). Further, a contact piece (13) is provided on the back surface of the seat plate so as to contact the seat frames (2), (2).

The chair of the present invention is constructed as described above, but as shown below, the chair stands upright at the front of the armrest frame (9) with its tip facing diagonally forward of the armrest frame (9). The memo board stand (14) may be formed to provide the memo board (15). The memo board stand (14) is fixed to the two leg pieces (16) and (16) and the upper ends of the leg pieces (16) and (16) as shown in FIGS. 4 (a) and 4 (b). It has a mount (17), and the mount (17) is provided with a nut (18).

The top plate portion (20) of the arm bracket (19) is placed on the mounting base (17) and fixed by screws, and the vertical plate portion of the arm bracket (19) is fixed. A hinge plate (22) is pivotally attached (23) to the (21) so as to be rotatable in the front-rear direction (Fig. 5). For rotation of the hinge plate (22), an arc-shaped guide groove (24) is provided in the arm bracket (19), a guide pin (25) is projectingly provided in the hinge plate (22), and the guide pin ( By engaging 25) with the guide groove (24), the memo plate (15) is restricted so as to rotate between a standing position and a position in which the memo plate (15) rotates in the front-rear direction and hangs down. The guide groove may be provided on the hinge plate side and the guide pin may be provided on the arm bracket side.

A mounting plate (26) to which the memo plate (15) is mounted is pivotally attached to the hinge plate (22) so as to be rotatable in the left-right direction. In the figure, sleeve plates (27), (27) protruding laterally are provided on the front and rear parts of the hinge plate (22), while the sleeve plates (27), 27 are formed on the front and rear parts of the mounting plate (26). The sleeve plates (28), (28) are provided along (27), and the sleeve plates (27), (27) and the sleeve plates (28), (28) are rotatably pivoted by rivets or the like. Wearing (29) (Figs. 6 (a) and 6 (b)). Further, an engaging piece (30) is formed on one side of the mounting plate (26), and when the memo plate (15) is erected and slightly tilted outward as shown in FIG. An engaging groove (31) is formed in the arm bracket (19) so that the engaging piece (30) is engaged (FIG. 7 (b)).

The memo plate portion is configured as described above, and the mounting plate (26) for mounting the memo plate (15), the hinge plate (22), the arm bracket (19), etc. are connected as described above. Since the arm bracket (19) is attached to the chair by screwing it onto the mount (17), the memo board is independent, making it easy to manufacture, repair and replace the memo board. Is.

Thus, the chair can be used as a chair with a memo board in the state shown in FIGS. 1 and 2, and if the memo board (15) is sequentially rotated in the directions of arrows (A) and (B), 8 (a), the memo plate (15) can be hung so as to be obliquely directed to the side of the front leg (5). Then, if the seat plate (10) is inverted in the direction of the arrow (C), a space is formed between the seat frames (2) and (2) as shown in FIG. The seat frame part of the can be stored from the front, and at this time, the memo boards do not collide. In the same manner, chairs can be stowed forward one after another. Note that the memo boards (15) can be stored one after another so as not to hit other memo boards in the same manner as described above even when they are erected as shown in FIG. 7 (a).

At the time of use, the seat plate (10) may be tilted and the memo plate (15) may be rotated by a reverse operation to the above. The same can be applied to a chair without a memo board.

[0019]

[Effects of the Invention] The present invention is configured as described above, and it is possible to store a chair by stacking the chair in the front-rear direction with the seat plate inverted, and moving the caster without moving the chair. Since it can be stored, it is convenient to handle, and even if the legs and other members are made of thick pipe material or heavy members, they can be handled easily, and even if a memo board is provided, it does not interfere with storage and is compact. Can be stored in.
