Description

Portable folding chair with backrest

The present invention relates to a portable folding chair, and more particularly to a portable folding chair having a seat back to effectively avoid a fall when riding.

At present, the fixed type of chair, such as a conventional traditional bench or a low chair, cannot be folded, so it is inconvenient to carry or store.

Furthermore, at present, in order to facilitate carrying the chair for use outside, the Scooter Chair (A) shown in Figure 8 is mostly a chair made of canvas and poles. The scout chair (A) is formed by pivoting the two sets of straight tubes (A1) in the middle. And the two horizontal tubes (A2) connected to the straight pipe (A1) are connected with a seat cushion (A3). Among them, the Scout Chair (A) has the advantages of simple manufacture, quick opening and closing operation and no space occupation. However, the scout chair (A) is liable to cause insufficient support force due to incomplete deployment during the opening and closing operation, thereby causing the scouting chair (A) to collapse. Moreover, the scout chair (A) cannot withstand too much weight, and thus it is easy for the occupant to fall accidentally. If the user does not aim the buttocks on the seat cushion (A3) of the scout chair (A) while riding, it may also cause a fall accident.

In order to improve the above-mentioned Scout Chair's lack of support and the inability to withstand too much weight, the user is less secure in riding. In other words, the Republic of China's new patent announcement No. M330795 "Folding Chair" is mainly made of plastic. The folding chair with the two-legged footboard, the four-folding board and the two-seat cushion board pivoted together, wherein the two-legged board and the four-folded board and the second seat cushion board are respectively connected to form a pivot, and two adjacent folds The plate and the two seat cushions are also connected to form a pivot; the user can easily and easily fold the folding chair into a plane by simply holding the handle on the seat cushion plate for convenient carrying and collecting.

In summary, the above conventional ones still have the following disadvantages to be improved:

1. At present, the general fixed type of chair cannot be folded, so it is inconvenient to carry or store.

2. At present, although the chair and leisure chair can be easily folded and carried out, but because the supporting force is insufficient, it can not bear too much weight, and it is easy to cause the occupant to fall, so there are safety concerns.

3. Although the "folding chair" is easy to fold and carry out, and has better supporting power, the user may easily fall off due to an unattended strength when riding, so there is a safety concern.

Therefore, in order to improve the current general fixed type of chair, it is impossible to fold, so it is inconvenient to carry or store. Moreover, in order to improve the current scout chair and leisure chair, it is convenient to fold to carry out the use, but the support force is insufficient, and the weight cannot be tolerated, and the occupant is easily injured. In addition, in order to improve the conventional "folding chair", it is convenient to fold and carry out, and has better supporting force, but the user may easily suffer from a fall injury due to an unattended strength when riding. Therefore, the present invention provides a portable folding chair having a seat back, comprising: a chair body comprising two support plates, four folded side plates and two folding seat plates, wherein the support plate, the The folding side plate and the folding seat plate are pivotally connected to each other, wherein one of the folding seat plates comprises a grip portion, wherein one of the support plates is connected with a back plate; The lifting portion, after the folding side plate and the folding seat plate are pivotally folded, the two supporting plates are brought closer to each other, thereby being converted from a solid state to a planar state.

Wherein, the back plate is slightly curved.

The pivoting manner is extended by the support plate and is provided with a plurality of bumps, and the bumps are respectively pivoted corresponding to the plurality of axle holes provided in the folding seat plate.

Wherein, the back plate and the support plate are integrally formed.

The effect of this creation is:

1. This creation is connected with a back plate on one of the support plates of the chair body, which is mainly for the occupant to lean on when riding, and does not cause a fall due to the strength of the reclining. Therefore, this creation is safer to use.

2. The creative chair system can be folded and conveniently carried out. Therefore, it is convenient to use.

3. The back plate to which one of the support plates is attached is slightly curved and can be flexed to conform to the back of the human body. This ensures a comfortable and safe ride.

4. The back panel disclosed in the present invention is slightly curved, and when the chair body is folded into a near-flat state, the back panel can be adapted to the leg of the human body, so that it is less troublesome when carried.

This creation is a portable folding chair with a seat back. The main technical features, objects and effects of the present invention will be apparent from the following examples.

First of all, please refer to the first to third figures. The creative department includes:

A chair body (1), the chair body (1) comprises two corresponding supporting plates (10), four two corresponding folding side plates (11) and two folding seat plates (12). Wherein, the support plate (10), the folded side plate (11) and the folding seat plate (12) are connected to each other in a pivotal manner. In this embodiment, one of the folding seat panels (12) includes a grip portion (120) for the user to grasp for convenient carrying. One of the support plates (10) is connected to a back plate (13). In this embodiment, the back plate (13) is integrally formed with the support plate (10), and the back plate (13) is mainly for the back of the occupant. In turn, it is possible to avoid a fall caused by a force that does not pay attention to the back.

The support plate (10), the folded side plate (11) and the folding seat plate (12) are pivotally connected to each other.
