There is a disadvantage that the chair should be cleaned on the surface of the chair, and the surface of the chair is exposed to ultraviolet rays, which causes discoloration and aging quickly. Fold the backrest so that it is in close contact with the bottom of the chair, and then turn it upside down to prevent rain and dust from entering the interior and improve cleaning obstacle structure to make cleaning easier. It is a chair that has dramatically increased efficiency.

Description

Stadium Stand Clean Chair {stadium's clean-seat}

The present invention relates to a chair structure fixed outdoors such as a stadium viewing stand, and the existing fixed open-air chairs are always exposed when the seat surface and the back of a person sit.

After rain or when cleaning the water, the seat gets dirty and contaminates the seat.

There is a drawback that the dust that is scattered when cleaning the broom is accumulated on the seat and that it needs to be cleaned every day with a mop.

The surface of the chair is exposed to ultraviolet rays, causing discoloration and aging quickly.

Can not be used to attach to the chair as a cushion due to rain

Narrow front and rear aisles make transportation and cleaning difficult.

It is inconvenient because the seat back is blocked at the back of the bottom stand, so it is not possible to sweep the garbage from the top stand to the bottom.

Brooms and garbage (cans, newspapers, etc.) are caught in the seat support hardware under the stand,

Since the plastic chair is completely fixed to the steel frame, there is no cushion in the bottom direction, making it hard to sit long and hard

In the present invention, the plastic chair back is shown in Fig. 2a 1 as the main body of the back, 2 is a plastic attached to the side of the main body and fixedly coupled with 1, and the bottom of the plastic chair is in the form of a hollow plastic box as shown in Fig. 2a. The steel rod is fixed to 6, and there is a hole right behind it, and the hole of the plastic chair is rotated. The plastic chair can be rotated around the axis 11, and the chair back and the floor are hinged around the right 4 axis. It is connected in the form so that the backrest can be folded and removed on the floor, and the waterproof cover 3 is semi-circular, and it is fixed to the floor to cover the hinge structure like an umbrella when standing upside down to prevent rainwater from entering the gap between the hinges. In Figure 2, the moment by the left steel weight and the plastic weight on the right about the 11 axis of rotation The moment on the right side acts as the center of gravity of the backrest moves to the left side when the backrest is folded on the floor, so the moment is the smallest and the greatest when the backrest is removed.The moment value is calculated by calculating the weight of the left steel weight. When the backrest is extended after installing the steel weight so that it is larger than the moment value when the backrest is folded and less than the moment value when the backrest is folded, the right moment is large. The chair's bottom touches the pad and stops, and the backrest touches the steel frame so that it can't be flipped anymore so that a person can sit on it. Falls forward by its own weight and adheres to the floor surface. The moment on the left side is greater than the moment on the right side, and the left steel weight begins to descend. Eventually, the plastic chair stands upside down and stops. To raise the chair upside down, hold the front part of the chair back and raise the bottom back. When the chair is not in use, the chair back is slightly pushed forward when the chair is not in use. As shown in Figure 2c, the center of gravity of the backrest is moved forward, and the moment about the 11th axis of Figure 2d is reduced so that it stands upside down as shown in Figure 1b by the steel weight built into the seat. As shown in 2c, the chair is standing with its back into the c-shaped backrest and the upper surface is in room 3 of Fig. 2a. As it is closed by sukaba

Completely prevents water from entering during rain and water cleaning

It also prevents dust from scattering while cleaning the broom, keeping the bottom and back of the chair clean at all times.

When exposed to the sun and the back of the chair to prevent UV discoloration and aging quickly

Since the bottom and back of the chair are protected from rain and dust, it is possible to use cloth-type cushions on the floor and back.

As the chair is standing, the passage between the front and rear seats is widened, and it is narrow during passage and cleaning, eliminating the inconvenient action.

The upside down position is more than 20 centimeters away from the wall of the stand, which makes it possible to sweep the trash from the top stand directly to the bottom stand for efficient cleaning.

The seat fixing hardware is more than 15cm away from the floor, so it doesn't catch the broom, and the garbage such as cans and newspapers can get caught in the seat supporting hardware.

It is a structure that can be conveniently used with one touch when folding or extending the chair.

The seat is moved up and down about the 11th axis of Fig. 2d, and the rubber pad No. 9 of Fig. 2d absorbs the shock of sitting and acts as a cushion while sitting in a chair, so the user's comfort is good and the inconvenience of sitting for a long time is small.

When the backrest is raised with the rubber-coated iron rod of Figure 2d, it does not make a shock sound and has a function of preventing the plastic chair back from being broken even when the chair is folded back by giving power to the back.

The design consists of a wall-mounted steel frame, a rubber pad for chair cushions, a plastic chair bottom plate and a hinged plastic backrest.

As it prevents infiltration of water during rain and water and dust scattering during cleaning, it is always kept clean so there is no problem of wiping with rags and various detergents at any time.

As it is not exposed to the ultraviolet rays of the chair use surface (bottom and the back), discoloration and the aging progress slowly and can use it for a long time like a new article

As it is protected from rain and dust, various types of cushions including cloth can be attached.

As the chair is erected, the passage between the front and back chairs is wider for convenient passage and cleaning.

The upper stand and the bottom stand are broken, so it is possible to sweep the trash from the upper stand to the lower stand, thus increasing the efficiency of cleaning.

Seat fixing hardware is more than 15cm away from the floor to prevent cleaning

Up and down cushion features of high-end chairs make it comfortable to use and less discomfort
