  An object of the present invention is to provide a folding chair for children that can be easily folded and unfolded.

According to a first aspect of the present invention, there is provided a folding chair for a child, wherein an upward bent portion provided at the upper ends of a pair of left and right rear legs is pivotally attached to the outside of a rearward bent portion provided at the upper ends of a pair of left and right front legs. A pair of front legs' rear bent parts are connected by backrest, and the left and right ends of the support frame with the front table attached to the upper ends of the upper bent parts of the left and right rear legs projecting upward from the rear bent parts. And a base portion of the support frame is held by a horizontal holding portion formed on the rearward bent portion, and a rear end of a seat plate disposed between a pair of left and right front legs and rear legs is provided. The left and right rear legs are held on the connecting rod and hinged so that the hinge shaft is on the front side, and the front end of the seat plate is held on the connecting rod connecting the left and right front legs. Before and after forming on both sides The direction of the long groove, is characterized in that fitted the connecting pin projecting from the front leg slidably.

  The folding chair for a child of claim 1 according to the present invention is such that the front leg and the rear leg are opened, and the table and the seat plate are horizontally opened. When lifted with one hand, the front legs and rear legs rotate inward about the pivot axis, and the seat plate is folded with the upper surface facing forward, and the support frame is also pivoted on the rear bent part. It turns to the inside as a center, and the whole is in a folded state. In this folded state, when the seat plate is pulled forward while the end of the table supported by the support frame is in contact with the floor surface, the front and rear legs open, and the seat plate expands horizontally. Therefore, when the support frame of the table is rotated to the front side, the base portion of the support frame is supported by the horizontal holding portion formed on the rear bent portion of the front leg, and the table is used in a state of being held horizontally.

  Since the folding chair for children of claim 1 according to the present invention can be easily converted from the use state to the folded state and from the folded state to the use state by lifting the backrest with one hand as described above, many It is very convenient in a nursery school that handles chairs.

  In addition, since the base of the support frame that is pivotally attached to the upward bent part of the rear leg is supported by the horizontal holding part that is long in the front and rear, even if a large load is accidentally applied to the front of the table, The shaft attachment is not damaged.

In addition, the rear end of the seat plate is held on the connecting rod connecting the left and right rear legs , and the hinge shaft is hinged so that it is on the front side, and the front end of the seat plate is placed on the connecting rod connecting the left and right front legs. together it is held by a coupling pin which projects from the front leg back and forth to form the right and left sides directions in the long groove of the seat plate fitted slidably, because omit conventional connecting links such as, fingers during handling There is no risk of pinching.

It is a perspective view of the unfolded state in the actual form of the folding chair for children which concerns on this invention. It is a perspective view of the folded state in the same embodiment. It is a front view of the expansion | deployment state in embodiment same as the above. It is a side view of the expansion | deployment state in embodiment same as the above. It is AA sectional drawing shown in FIG. It is explanatory drawing which shows the folding order of embodiment same as the above.

  Hereinafter, embodiments of the folding chair for children of claims 1 and 2 according to the present invention will be described in detail with reference to FIGS.

  Reference numeral 1 denotes a pair of left and right front legs having a rear bent portion 1 a at the upper end, the rear ends of the pair of rear bent portions 1 a are connected by a backrest 2, and the middle portion of the pair of front legs 1 is connected by a connecting rod 3. ing.

  Reference numeral 4 denotes a pair of left and right rear legs provided with an upper bent portion 4a at the upper end. The pair of upper bent portions 4b are overlapped on the outer side of the rear bent portion 1a, and the lower ends of the front legs 1 and the rear legs 4 are opened and closed forward and backward. As can be done, it is pivotally attached to the support shaft 5, and the middle part of the pair of rear legs 4 is connected by a connecting rod 6.

Reference numeral 7 is inserted between the pair of front legs 1 and the right and left pair of rear legs 4, a seat plate 7 placed on the the connecting rod 3 and the connecting rod 6, the connecting rod 6 to its rear end, the hinge 8 The connecting pin 10 protruding from the inner side of the front leg is slidably fitted in the longitudinal groove 9 which is engraved on both sides of the front side.

  Reference numeral 11 denotes a support frame of the table 12 formed by a pair of left and right arms 11a and an arm 11b connecting the front ends thereof. The rear ends of the left and right arms 11a are upwardly projecting upward from the rearward bent portion 1a. When the support frame 11 is pivotally attached to the upper end of the bent portion 4a by a support shaft 13 so as to be able to rotate back and forth, the base portions of the left and right arms 11a in the support frame 11 are bent backward. The table 12 is formed so as to be held in a horizontal state by being held on a horizontal holding portion 14 that is long on the front and rear sides formed on the upper surface of 1a. A long groove 15 is provided inside the left and right arms 11a of the support frame 11, and a protruding piece 16 protruding from the lower surface of the table 12 is slidably fitted back and forth in the long groove 15.

Reference numeral 17 denotes a belt having one end connected to the connecting rod 6, the other end connected to the support frame 11, and a removable connecting tool 18 provided in the middle portion.
