  Hereinafter, an infant chair (hereinafter simply referred to as “chair”) 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8. The arrow shown in each figure has shown the absolute direction in the space which arrange | positions the chair 10. FIG. The chair 10 in the present embodiment is configured by combining wood such as cypress. In addition, the material of the chair 10 is not limited to wood, and can be configured using other materials such as resin.

  As shown in FIGS. 1 to 4, the chair 10 is configured by combining two side plates (the right side plate 1 and the left side plate 2), the back plate 3, and the seat plate 4. The right side plate 1 and the left side plate 2 are arranged to face each other in parallel so as to be orthogonal to the left-right direction. The back plate 3 is provided in contact with the rear end portions of the right side plate 1 and the left side plate 2 while being orthogonal to the right side plate 1 and the left side plate 2 so as to be orthogonal to the front-rear direction. As shown in FIGS. 2 to 4, the side plates 1 and 2 and the back plate 3 are joined together by four dowels D1. The number of dowels D1 is not limited.

  The seat plate 4 is provided orthogonal to the right side plate 1, the left side plate 2, and the back plate 3 so as to be orthogonal to the vertical direction. The seat plate 4 is inserted into the groove portions 1g, 2g, and 3g formed in the side plates 1 and 2 and the back plate 3, respectively. As shown in FIGS. 2 to 4, the seat plate 4 and the side plates 1 and 2 are joined by two dowels D2. The number of dowels D2 is not limited.

  An infant who is a user of the chair 10 uses the chair 10 by sitting on the seat plate 4. In the seat plate 4, one end side recess 4 a is formed on one end side surface in the vertical direction, and the other end side recess 4 b is formed on the other end side surface. The one-end-side recess 4a and the other-end-side recess 4b improve the sitting comfort when the infant sits on the seat plate 4. A concave portion 4c is formed at the front end of the seat plate 4 so that the length in the front-rear direction of the central portion in the left-right direction is shortened.

  The side plates 1 and 2 are formed with one end 1a and 2a in the vertical direction and the other end 1b and 2b. In FIG. 1, the one end portions 1 a and 2 a are directed upward and the other end portions 1 b and 2 b are directed downward (the other end portions 1 b and 2 b are grounded to the floor surface). In the present embodiment, the posture of the chair 10 in which the one end portions 1a and 2a are arranged upward as shown in FIG. 1 is referred to as “upright posture”.

  As shown in FIG. 5A, the chair 10 can also be used in a posture in which the up-down direction is reversed from the upright posture. That is, the other end portions 1b and 2b are directed upward and the one end portions 1a and 2a are directed downward (the one end portions 1a and 2a are grounded to the floor surface). In the present embodiment, the posture of the chair 10 in which the other end portions 1b and 2b are disposed upward as shown in FIG.

  In the chair 10 according to the present embodiment, the seat plate 4 is provided at a position deviated from the central portion in the vertical direction of the side plates 1 and 2 to one side in the vertical direction (the lower side in FIG. 1) (see FIG. 2). ). In other words, the seat plate 4 is an inverted seat plate that is a distance from the end portion on the one end portion 1a, 2a side, rather than the upright seat plate height h1, which is a distance from the end portion on the other end portion 1b, 2b side. It is provided on the side close to the other end portions 1b and 2b so that the height h2 is increased. For this reason, when the chair 10 is used in an upright posture, the vertical position of the seat plate 4 is lower than the central portion of the chair 10 in the vertical direction. Conversely, when the chair 10 is used in an inverted posture, the vertical position of the seat plate 4 is higher than the central portion of the chair 10 in the vertical direction. As described above, the chair 10 can change the height of the seat plate 4 when using the upright posture and when using the inverted posture. Thereby, the height of the seat board 4 can be changed with the height of the infant who is a user.

  Moreover, as shown in FIG.5 (b), the chair 10 can also be used with the attitude | position which orient | assigned the back surface of the backplate 3 to the upper side. That is, the chair 10 in the upright posture or the inverted posture is rotated by 90 degrees on the opposite side of the back plate 3 and the back plate 3 is arranged facing upward. In the present embodiment, the posture of the chair 10 in FIG. By setting the chair 10 to the desk posture, an infant who is a user can perform learning and painting work on the back plate 3.

  Note that the desk chair 10 may be used as a chair (sitting on the back plate 3). Moreover, it is also possible to use it as a desk or a chair using the other upper surface in the state which earth | grounded either one of the both-sides board 1 * 2 of the chair 10 on the floor surface. Moreover, it is also possible to use one of the two chairs 10 and 10 as an upright posture or an inverted posture, the other as a desk posture, and the chairs 10 and 10 as a set of a chair and a desk.

  As shown in FIGS. 1 and 4, three convex shapes 11 and 21 are formed at one end portions 1 a and 2 a of both side plates 1 and 2. Specifically, three convex shapes 11 and 21 and concave shapes 12 and 22 are alternately formed. In addition, three concave shapes 13 and 23 having the same shape as the convex shapes 11 and 21 are formed on the other end portions 1b and 2b of the both side plates 1 and 2 at the same longitudinal position as the convex shapes 11 and 21. . Specifically, three concave shapes 13 and 23 and convex shapes 14 and 24 are alternately formed. The number of the convex shapes 11 and 21, the concave shapes 12 and 22, the concave shapes 13 and 23, and the convex shapes 14 and 24 is not limited to three. It is also possible.

  By configuring the chair 10 as described above, when the plurality of chairs 10 are adjacent to each other in a desk posture, the convex shapes 11 and 21 formed on the one end portions 1a and 2a as shown in FIG. It can be inserted into the concave shapes 13 and 23 formed in 2b and engaged with each other. For this reason, even if force is applied to one chair 10 in the vertical direction, it is difficult for the other chair 10 to be displaced.
