Please refer to FIG. 2 and FIG. 3 , the plurality of through holes 317 disposed on the second back plate 312 can circulate air to prevent the occupant's back from being stuffy, and the headrest setting portion 318 disposed on the first back plate 311 can be used for headrests The seat is used to support the head of the occupant, and the second handle portion 319 provided on the first back plate 311 is a perforation provided on the first back plate 311, and the second handle portion 319 can be folded in the When the chair 3 is folded into a seat, the folding chair 3 is moved by being held by a person's hand.

Among them, the material of the folding chair 3 is a single piece of plastic PP board, which can have better supporting force. Through the concept of origami, the structure of the chair is designed. Not only can it be fully flattened, but also a three-dimensional seat can be formed without any hardware accessories after being erected. The structure of the buckle is designed on the support parts on both sides of the chair, and the buckles on both sides of the back and the buckles on both sides of the seat are fastened to each other, so as to support the weight of the person falling back.

Using the elasticity and toughness of the PP plastic board, when people ride on it, it will naturally form an ergonomic recliner angle of 105~120, and the back and spine can achieve the effect of obedience, and can completely cover the buttocks to achieve leisure. , comfort and health purposes.

The height support plate 331 supports the front end of the seat plate 322, and has a design for supporting the legs, so that when the user rests, the legs will not feel uncomfortable due to the air. The structure design of the height support plate 331 is two The folding line is folded outward, and the last one below is folded inward, which will make the support plate 331 form an arc, so that the user's legs can be more relaxed, and the main design of the two reversed folding lines is an arc, which will not be folded when folded. It is so sharp, and it also uses the elastic properties of PP plastic. When the weight of the person is pressed, the place on the foot will not be flattened. In addition, the seventh assembly part 335 and the eighth assembly part 336 are fixed in the same way. The method of snapping is also used, and the method of interlocking up and down makes the structure of the tilting unit 33 more stable and prevents it from being opened due to the elastic force of the PP plastic.

The assembly method of the folding chair 3 can be completed in five steps to form a chair. First, the folding chair 3 with the appearance of a handbag is opened and flattened, and then the third assembly part 316 and the fourth assembly part on both sides are assembled. 324 are interlocked with each other, and finally the fifth combination part 325 and the sixth combination part 334, and the seventh combination part 335 and the eighth combination part 336, which support the legs below, are buckled with each other to complete the seat form.

In addition, in the folding step, first the third assembly part 316 and the fourth assembly part 324 , the fifth assembly part 325 and the sixth assembly part 334 , the seventh assembly part 335 and the eighth assembly part After the 336 is removed and the panels are flattened, the upper side panels 315 and the lower side panels 323 on both sides are folded inward, and then folded from top to bottom according to the fold line, thereby folding the folding chair 3 into the appearance of a handbag.

As can be seen from the above description, a folding chair 3 of the present invention does have the following effects:

1. Ride comfort:

When the folding chair 3 is folded into a seat, the two upper side panels 315 can support the first back panel 311 , the second back panel 312 and the third back panel 313 in a flat shape, which can provide support for the back of the occupant , so that the occupants are more comfortable.

2. Easy to carry:

When the folding chair 3 is folded, the appearance of a handbag can be formed, and the user can use the first hand part 337 to extract and move the folding chair 3, which is convenient to carry to the outdoors.

Three, not easy to deform:

When the third assembly part 316 and the fourth assembly part 324 are combined with each other, the relative angles of the first back plate 311 , the second back plate 312 and the third back plate 313 and the seat plate 322 can be fixed, and the The two upper side plates 315 and the two lower side plates 323 are mutually buckled, which effectively supports the downward pressure on the back of the occupant, prevents the folding chair 3 from being deformed, and forms an ergonomic recliner angle of 105-120, and the back and the spine can reach Obedient effect, more complete coverage of the buttocks.

To sum up, when the folding chair 3 is folded, the first assembly part 314 and the second assembly part 333 can be used to fix the appearance of a handbag, and the first hand part 337 can be used to carry it for outdoor use. 3. When folded into a seat, the third assembly portion 316 and the fourth assembly portion 324 are fastened to each other to fix the angles of the first back panel 311, the second back panel 312 and the third back panel 313, thereby providing seating The seventh assembly part 335 and the eighth assembly part 336 can fix the inclination angle of the seat plate 322, so that when the user is resting, the legs will not feel uncomfortable because of the air, so the present invention can indeed be achieved. purpose.

However, the above is only a preferred embodiment of the present invention, and should not limit the scope of implementation of the present invention, that is, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the description of the invention. , are still within the scope of the patent of the present invention.
