Description

{Single pedestal style audience chair}

[0001] The present invention relates to a single-seated-style seating chair, and more particularly, to a single-seated-style seating chair, which is different from a symmetrical type of seating structure, It is about a single perceptual style seat (stand-alone chair) that supports it.

In general, the seat is installed in a performance hall, an auditorium, a movie theater, etc., and includes a backrest fixing portion mounted on the frame, a seat mounted on the front of the backrest fixing portion and rotated up by its own weight to be reversed, (Legs) mounted on both sides of the fixing part and equipped with an armrest on the upper part thereof. The backrest fixing part, the legs, and the like are supported and supported on the floor of the room through a pedestal fixed through the anchor bolts. Therefore, when the chair is not used, the seat is automatically pivoted and reversed, so that the space occupied by the seat can be minimized. On the other hand, in a theater, a lecture hall, a lecture hall, a training hall, a hall, etc., the chairs are often arranged continuously in the side so as to be installed in a narrow space. In this case, the chair connected to the side of the theater or the lecture room may be referred to as a connected chair. The connecting chair defines a seating space for supporting the seat occupant, and a lower end of a panel- A seat back shaft and an arm rest are installed on the support frame, and a seat rotation shaft provided at both ends of the seat back is fixed to two opposite support frames via a shaft bracket Wherein a seat supporting the buttocks of the seated person is normally folded toward the backrest so as to minimize a space occupied by the seat, and when the seat is seated, the seat is folded forward to the backrest so that the buttocks I will put it on my desk.

However, in the case of a conventional connected chair, it is necessary to be connected to a neighboring chair, so that there is a disadvantage that installation constraints are imposed, and in addition, Which is cumbersome and time-consuming. In the case of a conventional seat, it is a structure of a symmetrical perception that two seated lairs (chair legs) are arranged side by side around a seat on which a seated person sits on a hip. Therefore, up to now, a chair is installed in a connection type which is installed adjacent to a theater side, but the means that each chair can be installed independently is not disclosed.

In addition, conventionally, there is no serious problem when a connected chair is installed in a straight shape. However, a difficult problem arises when the connected chair is installed in a curved shape instead of a straight shape. In the case of installing a plurality of connecting chairs in a theater, a theater hall, a lecture hall or the like, there may be a case where a plurality of connecting chairs are curved (that is, the adjacent connecting chairs face each other When the connecting chair is curved, the seat rotation shaft on both ends of the seating seat of the chair is in the form of a straight shaft, while each of the connecting chairs is provided with a leg function (Cushion bracket) on both sides for supporting the crankshaft supporting the crankshaft and a shaft support hole in which the seat rotation shaft of the seat (the seat itself is also referred to as a cushion because it has a cushion) is inclined at a constant angle (That is, a state in which the angle is not changed, not the straight shape). In this case, The sheet rotating shaft of both ends of the sheet extends linearly (straight), whereas the shaft engaging hole in which the sheet rotating shaft of the shaft bracket is inserted is not linear, Not only is it difficult to engage with the support hole but also the angle of the shaft support hole of the shaft bracket with respect to the seat rotation axis is changed even if the seat rotation shaft of the chair seat is coupled to the shaft bracket, The sheet rotating shaft is brought into contact with the outer circumferential surface in a wide plane so that the sheet rotating shaft rotates about the shaft due to the high frictional force between the shaft supporting hole of the shaft bracket and the sheet rotating shaft of the chair seat (that is, the high rotational disturbance frictional force between the shaft- When it does not turn properly in the support hole There is a problem that the seat of the chair can not be properly rotated on the door. The seat rotation axis of the seat is in the form of a straight bar and the shaft support holes of the shaft bracket are angled at a linear position so that the frictional surfaces of the seat rotation shaft and the shaft bracket are shifted without being arranged on the same axial line, And there is a problem that it is difficult to install the connecting chair in a curved shape. That is, in the past, it is difficult to install a connecting chair in a curved shape because each seat is commonly connected to each other based on the perception, except that the connecting chair is not an independent structure for each connected chair Or it can not be installed in a curved shape at all.
