Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a chair for infants, and in particular, the present invention relates to a chair for infants, and in particular, the backrest and seat part, excluding the supporting legs, can also be used as a cradle, if necessary. The invention relates to a chair for infants.

[Prior art and its problems]

Many infant chairs have been known in the past, but most of them are simply equipped with a so-called reclining mechanism that allows the backrest to move up and down. Even if there is a structure that allows for rocking,
Most of the structures are of the rocking chair type, in which the lower surface of the leg that serves as the support part is formed into an arc shape, and the swing of this arc part causes the entire chair, including the legs, to swing back and forth. Therefore, there was a problem in that troubles associated with rocking between the legs and the floor surface were likely to occur.

Recently, a chair for infants that can also be used as a cradle has been proposed, as described in Publication No. 48-29644, but in this case too, there is a rocking rack (link) between the two legs facing each other. It has a structure in which a basket (bucket seat) for placing the infant is suspended from the suspended rocking rack, and a pair of legs that also serve as armrests and a pair of links ( Or, because the entire bucket seat was not covered by a protective mechanism and was exposed, it would cause the bucket seat to swing accidentally if a child rested their arm on the armrest. Shortcomings were pointed out, such as the risk of fingertips getting caught between the link and the armrest.

[Problem that the invention attempts to solve]

The present invention attempts to deal with the problems of the prior art described above, and the legs supporting the chair body are placed and fixed on the floor, so that only the seat floor including the backrest can swing. In addition, by locating the rocking mechanism including the rocking arm described above inside the side plate constituting the seat floor, it is prevented from being exposed to the outside, and is thereby housed on the chair body. The purpose of this product is to be constructed so that it can be used extremely safely by young children.

[Means and actions for solving problems]

In this invention, in order to achieve the above objectives,
The above-mentioned chair body, in which the chair body and the legs supporting the chair body are constructed separately, is attached to the supporting legs via swinging racks so as to be able to swing freely; The upper half of the script body, which is the attachment part,
By placing it inside the side panels that make up the seat floor, it is prevented from being exposed to the outside,
This completely prevents the arms and fingertips of an infant placed on the chair body from being accidentally pinched by the swinging mechanism. , so that it can be operated as necessary by opening and closing the lock mechanism.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

The infant chair of the present invention is composed of a chair body A, support legs B that suspend and support the chair body, and a hanging rocking rod C that connects the two.

The chair body A is composed of a seat part 1 and a backrest part 2 attached to the rear end of the seat part 1 so as to be able to rise and fall freely. A side plate that also serves as an armrest is attached at a predetermined height, and on the inside of this side plate are support legs B, which will be described later.
The structure is such that the upper half of the figure can be positioned. (See FIG. 4) Further, mounting legs 11 . . . 11 for mounting the hanging swinging rods C are formed protruding from the back surface of the seat floor portion 1. In addition, the mounting legs 11...11 are the seat floor part 1.
It is formed so as to be parallel to the front-rear direction on the back surface of the.

The support leg B is made up of a script body 3 placed on the floor, a leg bar 4 erected in the center thereof, and a hanging plate 5 of the swing bar C attached horizontally to the upper end of the leg bar 4. The hanging plate 5 of the swinging rack C is formed with mounting holes 51, 51 at both ends to fit the end of the swinging rack C and hang it. There is.

The two script bodies 3, 3 attached in parallel positions facing each other are connected by connecting rods 31, 31 so as to maintain the distance therebetween. It goes without saying that the distance between the two script bodies 3, 3 described above must be large enough to allow the chair body A supported by them to swing within the width between them. In the center of the script body 3, there is a chair body A.
A fitting groove 32 in which a stopper 13 for regulating the swinging of the fitting groove 32 is fitted is provided in a vertically elongated recess.

The stopper 13 described above is attached to the inside of the side plate 12 constituting the seat floor 1 so as to be able to swing freely, and the photograph 14 for swinging the stopper is shown for convenience of operation. , are exposed on the surface of the side plate 12 (see FIG. 4). It should be noted that the above-mentioned operation camera 14 should be accurately attached to the back side of the side plate, and a leaf spring or the like should be attached to elastically support it from the back side in order to ensure accurate sliding. It is desirable to provide a stopping mechanism such as a click stopper in order to prevent the stop position from moving unnecessarily.

The swinging arm C is formed by bending a rod-shaped metal into a substantially U-shape from the front, and bending both ends thereof slightly outward to form the locking portion 52. The above-mentioned swinging rod C has the locking parts 52, 52 inserted into the mounting holes 51, 51 formed in the hanging plate 5, and is locked so as to be able to swing freely, and the horizontal rod 53 at the lower end is The seat is mounted by fitting into the ends of mounting legs 11 formed protruding from the back surface of the seat floor part 1. In addition,
Although not particularly shown, it is desirable to provide a mechanism for regulating the swing width of the chair body in order to prevent excessive swinging due to rough handling.

Various methods can be considered for regulating this case, but for example, a stopper is formed at an appropriate position on the side or lower surface of the seat floor 1, and the stopper comes into contact with the end of the mounting plate 5 of the swinging rack. It is effective to have a configuration that does not generate an amplitude higher than that.

Reference numeral 6 denotes a stopper for adjusting the inclination angle of the backrest 2, and is attached to the side plate 12 of the chair body 1. The above-mentioned stopper 6 has a large number of locking grooves 61...61 carved at predetermined intervals on its outer circumferential surface, and a locking groove 61...61 is provided on the back surface of the backrest part 2 so as to be able to swing freely. The end portion of the inclination angle adjusting rod 21 attached in such a manner can be fitted and locked. Reference numeral 33 denotes wheels for movement provided at the rear end of the script body 3. The wheel 33 described above is formed to be slightly lower than the supporting leg protrusion 34 provided immediately before the wheel 33, and when the tip of the script body 3 is lifted and tilted as illustrated in FIG. It is designed so that it can only be grounded.

[Effect of idea]

The features of the present invention configured as described above are as follows.

Since the chair body A is configured to be supported by the rocking levers C and C which are extended to the support legs B and B so as to be able to swing freely, the chair body A on which the infant is placed can be moved to the stopper 13. By releasing the lock, it can easily function as a cradle.

In particular, the present invention is designed to support the upper half of the support legs B and B that support the swinging arms C and C (the leg arm 4 erected in the center of the script body 3 and the hanging plate 5 horizontally attached to the upper end thereof). The cradle mechanism is made to stand up so that it is positioned inside the side plate that makes up the seat, and all the mechanical parts that perform rocking motion are shielded from the outside by this side plate, making it different from the conventional cradle mechanism. Completely avoid the danger caused by exposed parts of the mechanism that performs rocking motion, such as the risk of your arm or fingertips being caught between the rocking mechanism and the armrest to which it is attached. We were able to provide an extremely safe structure.

Stopper 1 attached to the side plate 12 of the chair body
3 is a fitting groove 32 formed in the center of the script body 3.
When fitted, the chair body A and the supporting legs B become fixed, and can be used in exactly the same way as a conventional infant chair. In this case, it is also possible to recline the entire chair by changing the fitting position between the inclination angle adjusting rod 21 and the stopper 6 provided on the side plate 5.

When the engagement between the stopper 13 formed on the side plate described above and the fitting groove 32 of the script body 3 is released, the chair body A can freely swing on the support leg B by the hanging swinging lever C. As a result, if an infant placed on the chair body A swings the chair body A by itself, or if a parent accompanying the child swings the chair body A, the child can easily shake the chair body A. The child will be able to move and function as a cradle.

Even when performing the above-mentioned function as a cradle, the backrest 2 of the chair body A can be reclined freely, so the infant can use the chair in various positions from sitting upright to lying down. You can receive the cradle effect while using it.

Even when performing the function as a cradle, the third part of the screen body is always placed and fixed on the floor, and only the part A of the chair body swings, so the conventional rocking type infant chair is not It does not cause problems such as damage to the floor surface.
