Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an infant chair that doubles as a cradle, with a seated body that can be rocked as needed. This article relates to an infant chair that doubles as a cradle.

[Conventional technology]

Separately constitutes a landing leg body with fixed side support parts provided at left and right places on the front side and left and right places on the rear side, and a sitting body with movable side support parts provided at left and right places on the front side and left and right places on the rear side, Front left fixed side support part and front left movable side support part, front right fixed side support part and front right movable side support part, rear left fixed side support part and rear left movable side support part, rear right fixed side support part and rear An infant chair that also functions as a cradle, in which the right movable side support part is connected by left, right, front, and rear links of equal length, and a seated body with a backrest is supported on the landing legs so as to be able to swing back and forth. is the distance between the upper connection points of the left front and rear links, the distance between the upper connection points of the right front and rear links, the distance between the lower connection points of the left front and rear links, and the distance between the right front and rear links. The distance between the lower connecting points of the link was the same length.

[The problem that the idea aims to solve]

If you observe a mother holding and rocking an infant, you will notice that at one end of the rocking motion, the infant's head is up, and at the other end, the infant's feet are up. In other words, an infant being rocked is not moving up and down parallel to the horizon during the rocking motion, but his head and feet are also moving up and down in an intersecting manner.

In the infant chair that also serves as a cradle, as described in the prior art, the seated body swings back and forth through left and right parallel crank devices formed by front and rear links. 7.8
As can be seen from the line a' connecting the front and rear movable side supports shown in the figure, the infant's head and feet do not move up and down alternately, but move in parallel, and the rocking motion is simple. The movements were not similar to those of a mother when she holds her infant and rocks her infant to comfort her or put her to sleep.

The object of this invention is to provide a new chair for a child that also doubles as a cradle, in which the rocking motion of the seat is designed to mimic the motion of a mother's arms.

[Means to solve the problem]

In order to achieve the above purpose, the chair for cutting infants according to the present invention, which also serves as a cradle, has fixed support parts 1, 1', 2, and 2' on the left and right parts of the front side and the left and right parts of the rear side. The leg body 3 and the seat body 7, which has movable support parts 4, 4', 5, and 5' on the left and right parts of the front side and the left and right parts of the rear side, are configured separately, and the front left fixed side support part 1 and Front left movable side support part 4, front right fixed side support part 1' and front right movable side support part 4', rear left fixed side support part 2 and rear left movable side support part 5
And the rear right fixed side support part 2' and the rear right movable side support part 5' are connected to left, right, front and rear links 8 of equal length, respectively.
8', 9, 9' to connect the seating body 7 to the landing leg body 3.
In an infant chair that doubles as a cradle and is supported so as to be able to swing back and forth, the distance between the upper connection points of the left front and rear links 8 and 9 and the upper connection of the right front and rear links 8' and 9' The distance between the lower connection points of the front and rear links 8 and 9 on the left side and the front and rear links 8' on the right side,
The distance between the lower connection points of 9' is longer.

〔Example〕

In the embodiment shown in the figure, fixed side supports 1, 1', 2, 2' are provided on the upper surfaces of the left and right parts of the front side and the left and right parts of the rear side via upward pillar parts 10, and the front and rear sides of the left side are fixed. The landing leg body 3 having a concave space 11 between the side support parts 1 and 2 and the right front and rear fixed side support parts 1' and 2' is connected to the right and left leg members 12 and 12' by the horizontal bar 13,
13' and a horizontal rod 14, and has stoppers (not shown) on the lower surfaces of both the front and rear ends of the left and right leg members 12, 12'.
5, 15', and separately from the landing leg body 3, movable support parts 4, 4', 5,
A reclining type backrest 6 provided with a seat 5' and a seat 7 with a table 6' are constructed.

Next, a seat 7 with a backrest 6 is placed in the concave space 11.
Invaginate the lower half of the front left fixed side support part 1
and front left movable side support part 4, front right fixed side support part 1', front right movable side support part 4', rear left fixed side support part 2, rear left movable side support part 5, and rear right fixed side support part 2. ' and rear right movable side support part 5' of equal length left, right,
The front and rear links 8, 8', 9, 9' connect the lower ends of the left and right links 8, 8' on the front side and the lower ends of the left and right links 9, 9' on the rear side with the horizontal rod 18, 1
By connecting at 8', the seating body 7 with the backrest 6 is assembled.
is supported on the landing leg body 3 so as to be swingable back and forth to obtain an infant chair body A which also serves as a cradle.

When obtaining this main body A, the front and rear parts on the left side are smaller than the distance between the upper connecting points of the left front and rear links 8 and 9 and the distance between the upper connecting points of the right front and rear links 8' and 9'. The distance between the lower connecting points of the links 8 and 9 and the distance between the lower connecting points of the right front and rear links 8' and 9' are made longer.

Further, an engaging hole 19 is provided above the intermediate portion of the left and right leg members 12, 12', and vertical monkeys 22 are provided in the left and right walls 20 of the seated body 7, respectively. When the seat member 22 is engaged with the engagement hole 19, the seating body 7 is prevented from swinging, and when the engagement is released, the seat body 7 is allowed to swing freely.

Further, elastic members 23 and 23' are fixed to the front and rear surfaces of the horizontal rod 14 so that the pillar portions 17 abut against each other downward, so that the range of swinging movement of the seated body 7 is restricted by the abutment.

The reclining type backrest 6 has a stopper 25 having a plurality of engagement notches 24 at predetermined intervals on the outer periphery, and a stopper 25 that is slidable on the back surface of the backrest 6 and has an engagement notch at the lower end. 24 and an inclination angle adjusting rod 26 which can be selectively fitted and locked.

[Effect]

When the seated body 7 is swung in a state in which the vertical monkey 22 is removed from the locking hole 19, the seated body 7 moves as shown in FIGS. As can be seen from the line a connecting ``, when the vehicle swings forward, the front end side rises, and when the vehicle swings backwards, the rear end side rises.

In other words, the seat 7 of the infant chair that also serves as a cradle according to the present invention swings in a manner that is not parallel to the horizontal line.

[Effect of idea]

Since the present invention has the above-mentioned configuration, when an infant is seated on the seat 7 and is rocked, the head and legs alternately move up and down during the rocking motion, and the baby is held in the mother's arms. It moves in a manner similar to that of , and is effective in achieving the intended purpose.
