The fifteenth embodiment is a perspective view of the child's chair of the third embodiment from the oblique front side, and the sixteenth figure is a perspective view of the child's chair from the rear of the oblique direction. In addition, the configuration of the third embodiment is substantially the same as the configuration of the second embodiment except for the case where it is specifically described, and the configuration substantially the same as that of the second embodiment is also required to be the same as that of the user in the second embodiment. The symbol and/or name of the component, and the description thereof is omitted.

(Configuration of Child's Chair) First, the configuration of the child's chair 1 according to the third embodiment will be described. As shown in the fifteenth and sixteenth aspects, the child chair 1 of the third embodiment includes a chair body 10, a seat portion 20, a backrest portion 30, and a connecting belt 40. The chair body 10 includes a leg portion 11 , an armrest 12 , a jig 13 , and a jig coupling portion 15 .

(Construction of Child Chair - Seat 20) As shown in Fig. 16, the seat portion 20 of the third embodiment is the same as the seat portion 20 of the first embodiment, and is passed through the seat portion near the front edge of the seat portion 20. The shaft 21 is rotated and supported by the chair body 10 in a rotatable manner.

(Construction of Child Chair - Connecting Belt 40) As shown in Fig. 16, both end portions of the connecting belt 40 of the third embodiment are fixed to the center portion of the clamp connecting portion 15 and the rear edge portion of the seat portion 20.

(Installation and Removal of Child Chair) Next, the installation and removal of the child chair 1 of the third embodiment will be described. The seventeenth and eighteenth drawings are side views of the child's chair, the seventeenth figure shows the state of setting or unloading, and the eighteenth figure shows the set state. The child chair 1 of the third embodiment is similar to the child chair 1 of the first embodiment, and is placed on the seat 3 after being transported to the vicinity of the seat 3 disposed near the table 2.

As shown in FIG. 17, the chair body 10 is suspended and supported by the armrest 12 abutting against the upper surface of the table 2 and the leg portion 11 abutting the upper surface of the seat 3, and by the chair body 10 After the seat portion 20 is hollowly supported by the seat 3, when the child is seated on the seat portion 20, the downward load is applied near the center of the seat portion 20 by the weight of the child. Thereby, the rear edge portion of the seat portion 20 is rotated downward with the seat portion rotating shaft 21 as the center. As the seat portion 20 is rotated, the connecting belt 40 fixed to the rear edge portion of the seat portion 20 is pulled downward, and the clamp connecting portion 15 fixed to the upper end of the connecting belt 40 is also rotated downward. Further, in conjunction with the operation of the jig coupling portion 15, the jig 13 is rotated about the jig shaft 14, and the tip end portion of the jig 13 is rotated upward to abut against the lower surface of the table 2. As a result, as shown in FIG. 18, the child's chair 1 is in a state in which the table 2 is held by the front end portion of the armrest 12 and the front end portion of the jig 13.

When the child chair 1 is removed from the seat 3, the jig coupling portion 15 is lifted upward. When the jig coupling portion 15 is rotated upward, the front end portion of the jig 13 that is in contact with the table 2 in conjunction therewith is rotated downward to be separated from the lower surface of the table 2. Therefore, as shown in Fig. 17, the child's chair 1 is in a state in which the table 2 is not held, and the child's chair 1 can be removed.

(Effect of the third embodiment) As described above, according to the third embodiment, a load is applied to the seat portion 20 by the weight of the child, and the jig 13 is moved in conjunction with the seat portion 20 to hold the table 2. That is, the child's chair 1 is automatically fixed to the table 2 by sitting the child, so that the setting work is extremely easy.

[III] Modification of each embodiment

The embodiments of the present invention have been described above, but the specific configurations and means of the present invention can be arbitrarily changed and improved within the scope of the technical spirit of the invention described in the claims. Modifications as described above will be described below.

(Problems to be solved and effects of the invention) First, the problems to be solved by the present invention and the effects of the invention are not limited to the contents, and the unresolved problems can be solved by the present invention, and the undocumented problems can be achieved. The effect may be that only a part of the problems described may be solved, and only a part of the described effects may be achieved.

(Relationship between Embodiments) Each of the embodiments described above can be combined with each other by any combination. For example, the length adjusting mechanism 41 of the second embodiment may be combined with the connecting belt 40 of the first embodiment or the third embodiment. Thereby, the relative position of the seat portion 20 and the backrest portion 30 can be adjusted in accordance with the body shape of the child, and the seat comfort can be improved.

(Seat Belt) In the first to third embodiments, a mechanism for holding a child's chair for a child is not provided, but a seat belt for preventing the child from falling may be provided in the child's chair. For example, as shown in Fig. 19, a three-point fixed seat belt 60 fixed by the seat portion 20 and the backrest portion 30 may be provided. When the child is seated on the child's chair 1, the seat belt 60 is used to hold the child, thereby preventing the child from falling.

(End cap) The end cap 16 can also be formed by a structure different from that of the first embodiment. For example, as shown in the twentieth figure, the outer shape of the end cover 16 may be formed into a substantially rectangular parallelepiped shape, and three or more types may be obtained (in the twentieth aspect, four types of H1, H2, H5, and H6 are available). The distance (wall thickness) is the distance (wall thickness) from the attachment position of the end cover 16 (the center position of the upper, lower, left and right of the insertion hole 16a) to each of the peripheral edges (side surfaces). Further, the end cover 16 may be formed in a polygonal shape of a pentagon or more, and formed into a deformed spherical shape to take a larger distance (wall thickness). In this case, the distance between the end cover 16 and the table can be finely adjusted. Further, by forming the end portion of the jig 13 (not shown in the twentieth diagram) into a cylindrical shape and forming the insertion hole 16a into a cylindrical shape, only the end cap 16 can be mounted. By directly rotating in the case of the end portion of the jig 13, the direction of the wall thickness can be adjusted, and the adjustment thereof can be performed more easily.
