Description

A prefabricated chair that can be packaged with minimal volume and a packaging method for the prefabricated chair

The present invention relates to a prefabricated chair that can be packaged with minimal volume and a packaging method for the prefabricated chair.

In general, office chairs include personal office chairs used in personal work spaces such as offices or study rooms, and public office chairs used in large spaces such as conference rooms or classrooms. Most of the above personal office chairs provide less fatigue even during long hours of work. Chairs with a tilt function that reclines when the back is leaned against the backrest are widely used, and the shared office chair is a frame chair or seat in which the back and seat are firmly connected to the frame so that it has only a simple seating function in consideration of economic efficiency and sturdiness. This folding chair is widely used.

In general, the legs of a swivel chair are fixed to the lower part of the shock absorber that adjusts the height to support the chair, and the number of split legs is 5 or 6, so they are in a radial form.

Since the legs of these swivel chairs are flat and wide, they were packaged in an assembled state by fastening the seat, backrest, shock absorber, and legs.

In this way, as all the chairs are combined and packaged, the packaging volume becomes too large, which takes up a lot of loading area, and makes it impossible to transport a large amount when transporting, which is a factor that increases the unit price of the chair. It has been like this.

In addition, since the leg is formed as one piece, if the branch leg portion on one side is damaged and a defect occurs, the entire leg is discarded. As a result, a lot of raw materials are consumed due to defects that occur during manufacturing, which is a factor in increasing the production cost.

The chair with the above structure has a complex structure and many unit parts, making it difficult to assemble the chair, significantly reducing workability, and the cost of the finished chair is high, making it difficult to generalize.

In particular, as the sale of products via the Internet has become popular in recent years, a lot of costs have been incurred in packaging and shipping the product. However, in the case of the above-mentioned rotary chair, the size of the rotary chair is large when packaged, so a lot of shipping costs are incurred, and the size of the chair during packaging is high. Problems with packaging being damaged during delivery due to protruding parts frequently occurred.

In addition, in relation to prefabricated chairs, prefabricated chairs with various shapes and configurations are provided in the prior art, but as described above, productivity is low and high cost due to the complex structure, frequent defects occur during use, the product is bulky when packaged, and the product is damaged. There continues to be a problem with the packaging being damaged during delivery due to protruding parts, resulting in low sales of folding chairs.

Therefore, the present invention was devised to solve the above-described conventional problems. According to an embodiment of the present invention, costs are reduced by minimizing the volume when packaging a prefabricated chair, frequent defects occur during use, and packaging is reduced. The purpose is to provide a prefabricated chair that can be packaged with minimal volume to prevent damage to its condition, and a packaging method for the prefabricated chair.

Meanwhile, the technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly apparent to those skilled in the art from the description below. It will be understandable.

First, when packaging begins (S1), all chair parts are reduced to minimum volume (S2). That is, the connecting leg 60 and the height adjustment means 50 are folded in a sliding manner, and the connecting link portion 30 and the armrest portion 40 are folded around the hinge 1 to minimize the volume.

Then, the lower end portion 14 of the seat portion 10 is opened using the detachable member 15, and the rear surface 23 of the backrest portion 20 is opened using the detachable member 24 (S3).

Then, a plurality of chair parts in the volume minimization mode are stored in the open inner space of the seat part 10 and the inner space of the backrest part 20 (S4).

And as shown in FIG. 8A, the lower end of the seat portion 10 is closed by the detachable member 15, and the rear surface 23 of the isotropic portion 20 is closed by the detachable member 24.

And as shown in Figure 8b, the seat part 10 and the backrest part 20 are attached to each other by the attachment and detachment means 80.

At this time, the backrest surface 22 of the backrest portion 20 and the seating cushion portion 12 of the seat portion 10 come into surface contact with each other, and the lower end portion 14 and the rear surface 23 become exposed surfaces.

Therefore, it is packaged in an overall rectangular parallelepiped shape, minimizing the volume during packaging to reduce costs, and preventing frequent defects and damage to the packaging during use.

And Figure 10a shows a perspective view of the seat part with chair parts stored in the inner space stored in the inner space of the backrest part in the second embodiment of the present invention. Additionally, Figure 10b shows a perspective view of the packaging state according to the second embodiment of the present invention.

When packaging begins (S10), as in the first embodiment, all chair parts are placed in a state of minimum volume (S20). That is, the connecting leg 60 and the height adjustment means 50 are folded in a sliding manner, and the connecting link portion 30 and the armrest portion 40 are folded around the hinge 1 to minimize the volume.

Then, the lower end 14 of the seat part 10 is opened by the detachable member 15, and the rear surface 23 of the backrest 20 is opened by the detachable member 24 (S30).

In addition, a plurality of chair parts in volume minimization mode are stored in the inner space of the seat portion 10, the compression cushion portion 21 is stored in the inner space of the backrest portion 20 (S40), and the seat portion ( 10) is stored (S50). At this time, a partition wall 2 may be installed on the seat portion 10 so that a plurality of chair parts can be safely stored.

Finally, the lower end is closed by the detachable member 15, and the rear surface 23 is closed by the detachable member 24.

Therefore, in the second embodiment of the present invention, packaging can be completed only with the volume of the backrest portion 20, thereby minimizing the volume during packaging, reducing costs, and preventing frequent defects and damage to the packaging during use.

In addition, the apparatus and method described above are not limited to the configuration and method of the above-described embodiments, but all or part of each embodiment can be selectively combined so that various modifications can be made. It may be composed.
