FIELD

The present disclosure relates to the technical field of multifunctional furniture, in particular to a folding chair, and specifically to a reversing folding chair.

BACKGROUND

A folding chair is indispensable in modern life. At present, there are kinds of folding chairs in the market, and a consumer may select different products based on different environments, seasons and preferences. For example, a folding chair made of warm cotton cloth or flannel is preferred in winter, and a cool mesh fabric or rattan cloth is preferred in summer. Conventionally, replacements of a seat cushion cover, a backrest cover and an armrest cover are completed generally by disassembly and assembly, resulting in low efficiency and poor operability. In addition, the folding chair in the conventional technology only has a folding function, and cannot realize reversing. Therefore, it is necessary to provide a folding chair which solves the problems.

In order to achieve the above objectives, the following technical solutions are provided according to the present disclosure.

According to the present disclosure, a folding chair is provided, which includes a front support, a rear support, a backrest plate, an armrest support, a backrest support, a seat cushion, an armrest sleeve, and a front-support sliding frame. The front support and the rear support are connected with each other. An end of the armrest support is connected with an end of the backrest support, the other end of the armrest support is connected with the rear support, and the other end of the backrest support is connected with the front-support sliding frame. The backrest support is in a quantity of two, the two backrest supports are respectively arranged on two sides of the front-support sliding frame, and the backrest plate is arranged on the backrest supports. The armrest sleeve is arranged on the armrest support. An end of the seat cushion is in shaft connection with the rear support, and the other end of the seat cushion is in shaft connection with the front-support sliding frame. The front-support sliding frame is sleeved inside the front support and is slidable inside the front support.

In a case that a lower end of the front support is located in front of a lower end of the rear support, a first surface of the seat cushion faces upward, a first surface of the backrest plate is opposite to the first surface of the seat cushion and a first surface of the armrest sleeve, and the backrest plate is located behind the seat cushion. In a relative rotation of the front support and the rear support, the front-support sliding frame is driven to slide upward, the backrest support and the armrest support rotate simultaneously, and thereby the lower end of the rear support is located in front of the lower end of the front support. In this case, a second surface of the seat cushion faces upward, a second surface of the backrest plate is opposite to the second surface of the seat cushion and a second surface of the armrest sleeve, and the backrest plate is located behind the seat cushion.

Further, the rear support includes an external support rod, an internal support rod, a connecting rod, and an intermediate cross rod, which are connected with each another. The external support rod is connected to the armrest support. The external support rod, the internal support rod and the connecting rod are connected in a U-shape. The intermediate cross rod is connected to the seat cushion.

Further, the lower end of the front support is configured to rotate from a front side of the lower end of the rear support to a rear side of the lower end of the rear support.

Further, the external support rod of the rear support is located on an outer side of the internal support rod of the rear support.

Further, the backrest support is located on an inner side of the rear support, and the front support is located on an inner side of the backrest support.

Further, the backrest support includes a backrest support body and a backrest sliding frame, where the backrest sliding frame moves along the backrest support body.

Further, the armrest support includes an armrest support body and an armrest sliding frame, where the armrest sliding frame moves along the armrest support body.

Further, the rear support includes a rear support body and a rear support sliding frame, where the rear support sliding frame moves along the rear support body.

Advantages of the present disclosure are as follows.

The folding chair according to the present disclosure has functions of folding and reversing. Switching of a seat cushion surface, a backrest surface, and an armrest surface can be realized by reversing, without disassembly. Therefore, an efficiency of switching is improved.
