【Example】

 Example 1 FIG. 1 is an overall perspective view of a baby chair of this example. The upper arm 2 is manufactured by bending a pipe into a U-shape having an opening, a tip end is covered with a cushion material 2a, and a rear part is attached with a seat 3 on which a baby sits. The pair of support arms 4 are bent into a U-shape having a hanging portion 4a, and the tip end portion is covered with a cushion material 4b and fixed to the upper arm 3. Reference numeral 5 denotes a fixture, which is fixed to the hanging portion 4a of the support arm 4 and extends in the same direction as the support arm 4 (opening of the upper arm 2), and a support member 6 which is fixed to the support member 6. The rotary body 8 is movably supported, and the elastic body 9 urges the rotary body 8 to rotate. That is, as shown in FIG. 2 which is a cross-sectional view, the rotating body 8 having the groove 8a formed in the peripheral edge thereof is rotatably attached to the rotating shaft 6a fixed to the supporting member 6. Further, an elastic body 9 using a torsion coil is inserted into the rotary shaft 6a, and an end portion is supported by a recess 8b formed in the rotary body 8 and the other end portion is supported by a support member 6, and the rotary body is supported. 8 is biased counterclockwise as shown in FIG.

Next, a method of attaching the baby chair having the above-described configuration to the table will be described. First, FIG. 3 shows a cross section of the state in which the rotary body 8 is rotated clockwise and a gap is formed between the rotary body 8 and the upper arm 2 and is inserted from the end of the table 1, and then inserted. As is clear from FIG. 3, the upper arm 2 is placed on the surface of the table 1, and the cushion material 4b at the tip of the support arm 4 contacts the back surface of the table 1. Further, since the rotating body 8 is biased counterclockwise by the elastic body 9, it is in a state of pressing the back surface of the table 1. Therefore, even if the upper arm 2 is pressed, it does not move due to the frictional resistance of the groove 8a formed on the peripheral edge of the rotating body 8. When removing the baby chair, the rotating body 8 is rotated in the clockwise direction and is pulled out while forming a gap with the back surface of the table 1. In this way, the baby chair of this embodiment can be mounted on the table by operating the rotating body 8, and after mounting, the rotating body is released and fixed by the action of the elastic body. . Therefore, you can attach it without forgetting to fix it, and it will not move due to the resistance of the groove when attached. Note that FIG. 4 is an improved version of the baby chair shown in FIG. 1, in which the shape of the support arm 4 is different. That is, the difference is that the support arms 4 projecting from both ends of the upper arm 2 are formed in a U-shaped connection, and a cushion material 4c is attached to the central portion. By forming the support arm 4 in this manner, the support arm 4 can be more stably attached to the table or the like via the fixture 5, and can be firmly attached without moving even when pushed from the horizontal direction. In addition, as described above, the support arm 4 is connected in a U-shape, a circle, an ellipse, a square shape, a triangular shape, or the like. In addition, the present invention is also effective for a baby chair having a fixture of Example 2 (FIG. 5) described later, and further for a baby chair having a conventional fixture (fixed with nuts) shown in FIG.

Example 2 FIGS. 5 to 7 show a baby chair having another configuration. The upper arm 2 is manufactured by bending a pipe into a U-shape having an opening, a cushion material 2a is covered at the tip, and a seat 3 (not shown) on which a baby sits is attached to the rear. The pair of support arms 4 are bent in a U shape having a hanging portion 4a, and the tip end portion is covered with a cushion material 4b and fixed to the upper arm 3. Further, a sandwiching body 11 which is rotatable around a rotary shaft 10 fixed to the hanging portion 4a of the support arm is attached. A groove 11b is formed at an end portion of the sandwiching body 11 so that the upper arm 2 can be engaged therewith, and in this example, a groove 11b is formed so as to be received. A rotary member adjuster 12 that can adapt to the thickness is rotatably attached. As shown in FIG. 6, the rotation adjusting tool 12 rotatable by the rotating shaft 13 is formed so that three kinds of different distances a between the rotating shaft 13 and the edge of the rotating adjusting tool 13 can be selected. Next, the mounting of the baby chair having the above-described structure will be described. The rotation adjusting tool 12 is rotated to a position corresponding to the thickness of the table 1 and inserted from the end of the table 1 (FIG. 7). When the baby is seated in the seat 3 in such a state, the weight of the baby pushes the clamp 12 downward through the upper arm 2, and the clamp 12 rotates about the rotary shaft 10. Receives a clockwise moment. On the contrary, the rotation adjusting tool 12 at the other end of the pinching tool 12 receives a counterclockwise moment, that is, a moment that pushes the back surface of the table 1 upward. As a result, the baby chair is clamped and fixed to the table 1. This way, the baby is fixed by the weight it sits on, so it is safe and easy to remove. As described above, the rotation adjusting tool is not always necessary, but by attaching it, it can be applied to tables of various thicknesses, which is more convenient. Also in the present embodiment, the support arm 4 can be made more stable by connecting it as shown in FIG.
