Description

[Detailed Description of the Invention] The present invention relates to a chair for infants, particularly a chair for infants that can also be used as a rocking chair.

The purpose of this invention is to provide a chair for infants that can be used as a rocking chair or baby rack when the legs are folded, and as a so-called Haiti Air when the legs are assembled and erected. .

Another purpose of this invention is that when used as a rocking chair air, the back rest can freely change its inclination angle, and when used as a Haiti air, the back rest can be raised to a certain level. To provide a chair for infants that maintains a stable angle and prevents an infant seated on the seat from accidentally falling off the seat when the seat is a Haiti Air chair.

Conventional chairs for infants whose height can be changed by adjusting the legs, and chairs for infants whose seat and legs are separable so that the height of the seat can be adjusted by attaching and detaching the legs. The chair was well known. However, all of the above-mentioned known chairs are constructed so that they can be used for the sole purpose of freely adjusting the height, and the legs can be folded (leg folding and leg extension). It was completely unknown that the function would be completely changed from Rocking Cheer Air to Haiti Air.

The present invention attempts to address these problems, and has been able to completely achieve its purpose by completing the invention described below.

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

The basic structure of the chair of the present invention is that front leg levers 3 and rear leg levers 4 are foldably attached to the lower surface of a chair body consisting of a seat portion 1 and a backrest portion 2. The seat part 1 is molded from hard synthetic resin or the like, and elbow rests 12, 12 of an appropriate height are integrally formed on both sides of the seat floor part 11. The backrest part 2 is made of the same material as the seat part 1. Armpit parts 22, 22 are formed on both sides of the backrest surface 21 so as to have a U-shaped cross section, and the lower end thereof is attached to the back of the seat part 1. It is pivotally attached to the end so that it can be undulated freely. 23
is an upright holding plate formed at the lower end of the back rest part 2, and as shown in detail in FIGS. 3 and 4, the back rest part 2
It is molded by extending the lower end to the back side. The extension width of the upright holding plate 23 is not particularly limited, but it must be wide enough to support at least the rear leg lever 4 on its lower surface. ), the rear leg rod 4 may be fitted into the fitting groove 13 of the rear leg rod 4 formed on the lower surface of the rear end of the seat portion 1 so as to cross this groove 13 to close the fitting groove 13 of the rear leg rod. A size that can be used is required. Reference numeral 24 denotes an elevation adjustment rod, and inserts both ends of the rod provided near the lower end of the back of the back rest part 2 into the guide grooves 14 for adjusting the inclination angle provided in the elbow rest parts 12, 12, and inserts the ends of the rod into A tightening knob 25 is attached to keep the inclination angle constant. Reference numeral 5 denotes a footrest attached to the tip of the seat floor portion 11, and is pivoted around a pivot 51 so as to be rotatable. The front leg rod 3 is formed into a planar U-shape, and the rear leg rod 4 is formed into a front square shape by extending a grounding rod 41 through the open part of the planar U-shape. are pivotally connected 6 in an X-shape at the intermediate portion in the length direction to form a so-called cross member structure. The front leg rod 3 has an open end pivotally attached to the bottom surface of the tip of the seat part 1 so as to be able to rotate freely, and when used as a chair, the parallel rod part bent into a U-shape is attached to the ground rod 31. I am trying to make it so that
The rear leg rod 4 has a U-shaped parallel rod 42 portion bent at the top, and the parallel rod 42 is fitted into a fitting groove 13 formed on the lower surface of the rear end of the seat portion 1. I'm trying to get it to stop. rear leg rod 4
As mentioned above, the fitting groove 13 is connected to the parallel rod 42 of the rear leg rod.
It is formed as a groove deep enough to fit the two parts, and the upright holding plate 23 of the backrest part 2 can pivot across the groove 13. Reference numeral 7 denotes a link plate whose base end is rotatably pivoted to the rear leg lever 4, and locking notches 71...71 are formed on the lower surface of the tip and at appropriate positions on the inner side thereof, and the front leg lever 3 is connected to the link plate 7. When the rear leg levers 4 are assembled in an X-shape, they are engaged with locking pins 33 protruding from the front leg levers 3, thereby adjusting the leg spacing (height of the chair). 8
is a support rod attached to the rear leg rod 4, and when the chair body is used as a easy or rocking chair, it can be stood up and the lower surface of the rear end of the seat portion 1 can be used instead of the parallel rod 42 of the rear leg rod 4. I support it. In addition, when using a rocking chair, this support rod 8
Since the use of is well known, a detailed explanation will be omitted. Further, the front leg lever 3 and the rear leg lever 4 are shaped with appropriate curvature in order to provide a locking function, and this point is also known.

The present invention configured as described above has the following features.

Combine the front leg lever 3 and the rear leg lever 4 so that they form an X-shape on the side, open the two leg levers, and then open the rear leg lever 4.
It can be easily used as a chair (Haiti Air) by simply fitting and locking the parallel rods 42 that appear at the upper end onto the underside of the seat 1, and it can be easily used by closing (folding) the opening of the leg rods. Can be easily changed to Rock King Cheer.

Even when the chair is used as a Haiti Air, the height of the chair can be easily adjusted by changing the distance between the front leg levers 3 and the rear leg levers 4.

An upright holding plate 23 of the rear leg lever 4 is provided with an appropriate width to protrude from the lower end of the backrest part 2 toward the back side, and this upright holding plate 23 is connected to a fitting groove 13 formed on the lower surface of the seat part 1.
Since it is configured to pivot while crossing the rear leg lever, if the back rest part 2 is not raised when used as a Haiti Air, the fitting groove 13 will be blocked by the upright holding plate 23 of the back rest part 2, and the rear leg lever will be closed. The parallel rods 42 of 4 cannot be fitted, so if the backrest 2 remains tilted (reclined), it cannot be assembled as a Haiti Air, but safety is guaranteed if it can be assembled. It is expected to be done. In addition, once assembled as Haiti Air, the upright holding plate 23 formed at the lower end of the back of the backrest 2 is attached to the parallel rod 4 of the rear leg rod 4.
Since it is supported by two parts, even if the tightening knob 25 is loosened, the standing angle of the back rest part 2 can always be maintained at a constant angle, and the angle of the back rest part 2 can be unexpectedly changed. It is a highly safe structure that can completely prevent the dangers caused by this.

Whether it is used as a chair (Haiti Air) or as a rack (Rocking Chair Air), it is constructed so that the components for the other function do not get in the way at all. .
