Description

Audience chair leg assembly}

The present invention relates to a perception for an audience chair, and more particularly, to a perception for an audience chair, which is designed not to require post-processing after a perceptual molding, shortens the perception production process, eliminates various causes of defective products, It is related to the perception of a new audience chair that can be varied design and has many useful functions that can be continuously serviced by different product combinations, if necessary, for existing purchasers.

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- And a pivot support shaft provided at both ends of the support frame is disposed in front of the backrest and supported by two opposite support frames through a seat bracket, The connecting seat of the above structure is structured such that the seat supporting the buttocks of the seated person is normally folded toward the backrest so as to minimize the space occupied by the seat, and when the seat is seated, the seat spreads forward to the backrest, And then sit down.

However, in the case of the conventional connecting chair, many post-processes other than painting are often required after the perceptual molding, and the productivity is decreased due to an increase in the number of production processes due to the addition of various post-processes. In addition, since there are various post-processes in the past, there are problems in that various causes of defective products are caused. In addition, once installed in a chair, there is a problem in that it can not sufficiently satisfy diverse needs (product variation design) because various types of products and textures can not be saved. In addition, since customers who have already purchased the service must replace the service with a new one, there are disadvantages in terms of smoothness of service and flexibility of service.

In addition, in the case of a chair that is installed at the most end of a connected chair, that is, the chair on the left (left) and the chair on the right (right) There is a problem in that the structure of the intermediate crest for the middle chair (middle crest) installed between the chairs of the chair is different, and therefore, the crest must be manufactured in three kinds. The lower footrest of the crust is anchored to the floor of the chair installation place with anchor bolts. In the past, the left crest angle, the right crest angle, and the middle crust angle are different from each other. I have a problem to do. In other words, there has been a problem in that, in the past, there has been a problem that the crest support for the chair should be divided into three types of the left crest, the right crest and the middle crest, and the three types of crests must be manufactured. And further, since the crust is separately manufactured into three kinds, there is a disadvantage in terms of productivity and the like.

In addition, the note stand is installed so that it is supported by one side of each chair. In the past, the note stand occupies one space of the seat by the thickness of the seat. In such a case, The central portion of the seat becomes eccentric. That is, when the center portion of the backrest is the correct position, the center portion of the seat is disposed at a position offset sideways in the center portion of the backrest due to the note space.

Therefore, since the center portion of the seat for supporting the buttocks is in the eccentric position while the seated person is sitting on the seat, the seat occupant feels inconvenience at the time of sitting. In other words, the seat should be installed at a position where the seat is shifted to the side as much as the space occupied by the memo stand. When the seat occupant sits on the seat installed after the center portion is moved sideways, the seat occupant can not be supported by the seat in a balanced manner. It is supported at the eccentric position shifted to one side, so that it does not feel comfortable at sitting and feels uncomfortable. An unbalanced supporting state in which the buttocks of the seated person are supported on one side with respect to the seat and the other on the other side is supported more securely so that a stable and comfortable sitting can not be achieved when the seat occupant is seated and seated in an uncomfortable posture, The problem is that you can not sit down. However, in order to adjust the center of the seat so as not to be eccentric, if the side of the seat which is not provided with the memo stand is reduced by the space of the memo stand, the size of the seat becomes smaller and the area supporting the buttocks of the seated person is reduced. And there is a disadvantage that it is necessary to leave one space of the sheet unnecessary. As described above, various problems due to the center eccentricity of the sheet occur particularly when the memo pad is of the exposed type.

Domestic public utility model 20-2010-0004466 (publicized on April 30, 2010) Korean Registered Utility Model No. 20-0345255 (registered on Mar. 4, 2004) Korean Registered Utility Model No. 20-0375177 (registered on January 28, 2005)

In the present invention, the seat is designed to be empty as much as a space for a note, There is no case where the seat is set to be empty as much as the space for the memo, so that the center of the seat is not eccentric. That is, when the center portion of the backrest is in the correct position, the center portion of the seat is not disposed at a position offset sideways in the center portion of the backrest due to the space of the memo.

Accordingly, the center portion of the seat supporting the buttocks is not in the eccentric position, and is located at the central portion that balances the left and right positions of the buttocks of the seated person in a state in which the seat occupant sits on the seat. Therefore, Allow seating. In other words, in the present invention, the seat is not required to be installed at a position where the seat occupies the space occupied by the note pad, and the seat occupant does not sit on the seat installed after the center portion is moved sideways, So that the user feels comfortable at the time of sitting. In addition, in the present invention, since the center portion of the seat is not eccentric, there is no case in which the side portion of the seat on which the note pad is not provided is not reduced by the space of the note pad, so that the size of the seat is reduced and the area supporting the buttocks of the seated person is reduced There is no work to be done. Therefore, it makes a considerable contribution to making the seat as comfortable as possible, and it also has the effect of eliminating the disadvantage that one side of the seat should be left empty. Particularly, it can be said that the present invention is more effective when the memo group is of the exposure type.

1. The basic (exposed) type is the most basic combination of diecasting crutches, armrests, backrests (9) and seat brackets (6) and emphasizes the metallic texture and shape of the perception itself. There is an effect of breaking the image.

2. The memo stand type is used by attaching the memo stand (20) to the perception, and it can be applied to various environments by attaching various types of memo boards ranging from medium size to large size. The feeling of luxury is emphasized by the design of the note pad 20 integrated with the perception even though it is the exposed type note pad 20.

3. The slide cover type is a combination of the slide cover with the exposed crust, and as described above, it is possible to use it efficiently in all the processes from transportation to installation by a simple method of pushing and fixing toward the center of crust as described above.

4. The memo-to-cover type is a manner in which a pair of plate-shaped memo-to-cover 40 is wrapped and attached on both sides of the memo-to-expose crest. Such a note-to-cover type has a high-quality feeling with a structure capable of covering even the large-size memo stand 20 without requiring additional space.
