Description

A foldable seat

technical field

The utility model belongs to the technical field of daily necessities, in particular to a foldable seat.

Background technique

Seats are essential supplies in daily life. With the improvement of people's living standards, people have put forward higher and higher requirements for the structural design of seats. In addition to the traditional riding function, people require that the seat is easy to store, so that when the seat is not in use, it can be stored to save space in the home. Therefore, in the prior art, there are many kinds of seats that can be changed in structure, through which the volume can be reduced and the convenience of storage can be improved. Existing variable-structure seats are usually equipped with relatively complex deformation structures, which not only lead to complex overall structure of the seat, increased cost, reduced structural strength and service life, but also lead to cumbersome deformation operations, and there may be a risk of injury during the operation .

Utility model content

The utility model provides a foldable seat with simple structure, convenient folding and storage, high structural strength and long service life in order to solve the technical problems existing in the known technology.

The technical solution adopted by the utility model to solve the technical problems existing in the known technology is: a foldable seat includes four uprights with universal rollers at the bottom, and between the tops of two adjacent uprights There is a lower folding device between the upper folding device and the bottom, and a vertical insertion rod is provided at the top center of each column, and a rectangular canvas cushion with jacks at the four corners, each insertion rod is respectively Insert it into a socket of the canvas cushion; the upper folding device includes an upper end in the middle and an upper connecting rod hingedly connected to both sides of the upper end, and the other ends of the two upper connecting rods are respectively hinged to the top of the corresponding side column On the side wall, the lower folding device includes a lower end in the middle and lower connecting rods hingedly connected to both sides of the lower end, and the other ends of the two lower connecting rods are respectively hingedly connected to the bottom side walls of the corresponding side columns.

The advantages and positive effects of the utility model are: the utility model provides a foldable seat with a simple and reasonable structural design. Compared with the existing structure convertible seat, the technical solution provides a new foldable design and folding structures. The tops and bottoms of the four columns are respectively connected by an upper folding device and a lower folding device. After pulling each column outward to fully expand each folding device horizontally, the canvas cushion is also unfolded to form a seat with a complete structure. Chair, push each column inward to gather them, each folding device shrinks into a V shape, the canvas seat cushion hangs down into the space between each column, the folding storage operation is very convenient, the volume of the whole seat after folding is small, only It is about one-fifth of the expanded volume and does not take up storage space. Compared with the existing deformation structure, the folding device composed of the upper and lower ends and the upper and lower connecting rods adopted in this technical solution has a simple structure, high strength, reliable connection, and will not be damaged or damaged during long-term use. Wear and lose function, long service life.

Preferably: a group of universal rollers at diagonal positions are brake rollers.

In the figure: 1. Inserting rod; 2. Canvas cushion; 3. Upper connecting rod; 4. Upper end; 5. Column; 6. Lower connecting rod; 7. Lower end; 8. Universal roller.

Detailed ways

In order to further understand the content of the invention, features and effects of the present utility model, the following examples are described in detail as follows:

Please refer to the unfolded state of the seat shown in Fig. 1. The utility model includes four uprights 5 with universal rollers 8 at the bottom, an upper folding device between the tops of two adjacent uprights 5, and an upper folding device between the bottoms. There is a lower folding device, and a vertical insertion rod 1 is provided at the top center of each column 5, and a rectangular canvas cushion 2 with jacks at the four corners is also included, and each insertion rod 1 is inserted into the canvas cushion respectively 2 in one jack. Universal roller 8 is set to facilitate the movement of the folded seat. In this embodiment, a group of universal rollers 8 at diagonal positions are selected as brake rollers, and the user can step on the brake after the seat position is adjusted. Brake pads on rollers.

The upper folding device includes an upper end 4 located in the middle and an upper connecting rod 3 hingedly connected to both sides of the upper end 4, and the other ends of the two upper connecting rods 3 are respectively hinged on the top side wall of the corresponding side column 5; The device includes a lower end 7 located in the middle and lower connecting rods 6 hingedly connected to both sides of the lower end 7. The other ends of the two lower connecting rods 6 are respectively hingedly connected to the bottom side walls of the corresponding side columns 5.

After pulling each column 5 to the outside to make each folding device fully expand horizontally, the canvas cushion 2 also unfolds thereupon to form a seat with a complete structure.

Figure 2 is a schematic diagram of the folded structure of the seat. It can be seen that the way of storage and folding is as follows: push each column 5 inward to gather them, and each folding device shrinks into a V shape (the upper folding device shrinks downward to form a positive V shape, and the lower folding device The device shrinks upwards to form an inverted V shape), the canvas cushion 2 hangs down and enters the space between each column 5, and the canvas cushion 2 can also be directly taken off.
