Please refer to Fig. 2 and Fig. 3, the plurality of through-holes 317 arranged on the second backboard 312 can circulate air to prevent the back of the occupant from being stuffy, and the headrest setting part 318 arranged on the first backboard 311 can provide a headrest Set, use the chair to support the head of the occupant, the second handle 319 that is arranged on the first backboard 311 is a perforation that is arranged on the first backboard 311, and the second handle 319 can be folded When the chair 3 is folded into a seat, people hold it by hand, so that the folding chair 3 can be moved.

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 on the chair is designed. Not only can it be flattened in an all-round way, but also a three-dimensional seat can be formed without any hardware accessories after being assembled. The structure of the buckle is designed on the supporting parts on both sides of the chair. The buckles on both sides of the back and the buckles on both sides of the seat are interlocked to support the weight of the person falling backward.

Utilizing the elasticity and toughness of the PP plastic board, when people sit on it, it will naturally form an ergonomic recliner angle of 105~120 degrees, and the back and spine can achieve a comfortable fit, and can completely cover the buttocks to achieve leisure , comfort and health purposes.

The heightening board 331 raises the front end of the sitting board 322 and has a design for supporting the legs, so that when the user is resting, the legs will not feel uncomfortable due to vacating. The structural design of the raising board 331 is based on two Folding the folding lines outwards, and folding the last one below inwards, will make the riser 331 form a radian, allowing the user's legs to be more relaxed, and the main design of the two reflexed folding lines is an arc, so that they will not bend when folded. It is so sharp, and it also utilizes the elastic properties of PP plastic. When the weight of a person is pressed down, the place near the feet will not be flattened. In addition, the fixing method of the seventh combination part 335 and the eighth combination part 336 is the same. The way of buckling is also used to buckle each other up and down to make the structure of the tilting unit 33 more stable and prevent it from being bounced apart due to the elastic force of PP plastic.

The assembly method of the folding chair 3 can be completed in only 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 324 are interlocked, and finally the fifth combination part 325 and the sixth combination part 334 of the lower support leg, and the seventh combination part 335 and the eighth combination part 336 are interlocked to complete the form of the seat.

In addition, in the folding step, firstly, the third combination part 316 and the fourth combination part 324, the fifth combination part 325 and the sixth combination part 334, the seventh combination part 335 and the eighth combination part After 336 is untied and the plates are flattened, the upper side panels 315 and the lower side panels 323 on both sides are folded inwardly, and then folded from top to bottom according to the fold line, so that the folding chair 3 is folded 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 form, which can provide support for the back of the occupant. , making passengers more comfortable.

Two, easy to carry:

When the folding chair 3 is folded, it can form the appearance of a handbag, and the user can use the first hand portion 337 to pick up and move the folding chair 3 , which is convenient for carrying it outdoors.

Three, not easy to deform:

When the third combination part 316 and the fourth combination part 324 are combined with each other, the relative angles of the first backboard 311, the second backboard 312, the third backboard 313 and the seat board 322 can be fixed, and the The two upper side panels 315 and the two lower side panels 323 are interlocked to effectively support the downward pressure on the back of the occupant, prevent the folding chair 3 from deforming, and form an ergonomic recliner angle of 105-120°, and the back and spine can reach The fit effect can completely cover the buttocks.

To sum up, when the folding chair 3 is folded, it can be fixed into the appearance of a handbag by using the first combination part 314 and the second combination part 333, and can be carried outdoors by using the first hand part 337. The folding chair 3 When folded into a seat, the third combination part 316 and the fourth combination part 324 are interlocked to fix the angles of the first backboard 311, the second backboard 312 and the third backboard 313, thereby providing seating The support of the back, the seventh combination part 335 and the eighth combination part 336 can fix the inclination angle of the seat board 322, so that when the user is resting, the legs will not feel uncomfortable due to vacating, so the present invention can indeed be achieved. purpose.

But what is described above is only a preferred embodiment of the present invention, and should not limit the scope of the present invention with this, that is, all simple equivalent changes and modifications made according to the patent scope of the present invention and the description of the invention , all still belong to the scope covered by the patent of the present invention.
