Description

[Detailed description of the invention] This invention relates to a dining table chair for infants.

Conventionally, children's dining chairs, which are composed of a pair of left and right side frames, a seat material and footrest installed between the side frames, and a backrest that stands up from the rear edge of the seat material, generally cannot be folded. Therefore, it had the disadvantage that it could not be stored at a low volume when it was not needed.

The purpose of this invention is to eliminate the above-mentioned drawbacks by making it less bulky when folded and by eliminating the need for a lock to maintain the unfolded state via metal fittings when unfolded.

This idea forms a pair of left and right side frames with an elbow rest and the rear and front legs that extend from the front end of the arm rest, and connects both sides of the front end of the seat material with a pin at the top of the front leg and links. Both sides of the rear end of the seat material are attached to the upper part of the rear legs through the seat material, and the lower end of the backrest is rotatably attached to the rear edge of the seat material, and both sides of the backrest are rotatably attached to the end of the arm rest. Furthermore, the end of the side rod extending from both ends of the footrest is rotatably attached to the rear leg, and the stop rod for the footrest is installed on the front leg, and a side link is interposed between the stop rod and the side rod. To provide a dining table chair for infants which can be folded up by pulling up the footrest and unfolded by lowering the footrest.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, 1 and 1' are a pair of left and right side frames, and these side frames 1 and 1' are attached to an elbow rest 2 and an upper end rotatably attached to the front end of this elbow rest 2 via a pin 3. It is composed of legs 4 and front legs 5.

Reference numeral 6 denotes a seat material, and the seat material 6 has both sides of its front end pivotally supported on the upper part of the front leg 5 via a pin 7, and its upper and lower ends are pivotally supported via a pin 8 between the upper part of the rear leg 4 and the middle of both sides. It is attached via link 9.

Reference numeral 10 denotes a backrest that is provided on the rear edge of the seat 6 and rotates up and down.
2 is attached so that it can be raised and rotated.

Furthermore, the ends of armrests 2 are attached to both sides of the backrest 10 via pins 13.

Reference numeral 14 denotes a footrest, and the ends of side rods 15 projecting rearward from both sides of the footrest 14 are rotatably attached to a rod member 16 connecting both rear legs 4 below the seat member 6.

Reference numeral 17 denotes a stopper lever installed on the front leg 5 so as to stop the footrest 14 when the side lever 15 is lowered to a horizontal position.

A side link 18 has one end rotatably attached to the stopper rod 17, and the other end of the side link 18 is rotatably attached to the side rod 15 via a pin 19.

Note that the auxiliary table is omitted in the illustration, but
Both side rods of the auxiliary table may be rotatably attached to both sides of the backrest.

The dining chair for infants according to this invention has the above-mentioned structure, and the side link 18 rotates in the standing direction (counterclockwise in FIG. 2) by pulling up the footrest 14 as shown in FIG. through the hind legs 4
The front leg 5 is rotated counterclockwise in FIG. 2 so as to approach.

At this time, since the link 9 is rotated in the direction that occurs as the front leg 5 is rotated, the seat member 6 is pushed back.

Thus, the front legs 5 and side rods 15 are made parallel to the rear legs 4.

At this time, the backrest 10 is bent and folded toward the seat material 6 so as to overlap (as shown in FIG. 4).

Next, when the backrest 10 is pulled up, the front legs 5 are pushed open while pushing out the seat material 6.

When the side lever 15 of the footrest 14 is rotated in the direction of falling down, the rear legs 4 and front legs 5 are opened in an inverted V-shape via the links 9 and side links 18 that rotate in the direction of falling down, and the stopper lever 17 is opened. Foot rest 14
to maintain the expanded state.

As described above, according to the infant dining chair of this invention, by pulling up the footrest, the front legs are attracted to the rear legs via the side links that rotate in the rising direction, and the links are rotated in the falling direction. The backrest is folded onto the seat, and at the same time, the front legs and side beams of the footrest are made parallel to the rear legs, so that the seat can be folded automatically.

In addition, when the backrest is pulled up and the side levers on which the foot rests are rotated in the direction of falling down, the front and rear legs are opened in an inverted V-shape, and the backrest is erected on the rear edge of the seat that has been returned to the horizontal position. So it can be expanded automatically.

In particular, the stopper lever and the side lever for the footrest are connected by a side link, and the seat material is attached to the rear leg via the link, and when deployed, the footrest is supported by the stopper lever, and the side link is in a collapsed state. Therefore, it cannot be folded unless the footrest is pulled up.

This eliminates the need for locking metal fittings or the like to maintain the unfolded state of the chair.
