The present invention relates to a prefabricated chair, and more particularly, to a prefabricated chair which is simple to assemble and disassemble by being provided with a frame at the back of the bench and the end of the seat plate, and which can be firmly assembled during assembly.

 Conventionally, benches installed in a park are often bulky and integral, and thus, when carrying a large amount of benches, there is a problem that a small amount of benches must be repeatedly carried several times in a vehicle having a limited load.

Therefore, the present invention has been made to secure and solve the drawbacks of the prior art,

It is an object of the present invention to provide a lightweight and prefabricated chair having a small volume by providing an upper horizontal frame and a lower horizontal frame at each end of the backrest and seat of the bench, and firmly fixing the frame and the auxiliary frame with fixing bolts. It relates to a bench used in parks and rest areas that are not easily broken.

In order to achieve the above object, the present invention provides a plurality of seats comprising a backrest and a seat plate and at least one connection frame in which a plurality of seats are arranged side by side and each seat side end portion is fitted into a fitting groove; An upper horizontal frame having a second fitting groove in which the upper end portion of the backrest portion is fitted in a length direction; It is to provide a prefabricated chair characterized in that the lower horizontal frame is formed in the longitudinal direction of the third fitting groove is fitted to the end of the seat plate portion.

(Example)

Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of a prefabricated chair according to the present invention, FIG. 2 is an exploded perspective view of a chair part according to the present invention, and FIG. 3 is an exploded perspective view of a leg part according to the present invention. 4 is an enlarged cross-sectional view of a portion according to the present invention, Figures 5a, 5b is an enlarged cross-sectional view of a portion showing a seat and the connection frame according to the invention, Figure 6 is a cross-sectional view taken along line A-A 'in accordance with the present invention. 7 is an enlarged cross-sectional view illustrating a cross-sectional view of another embodiment of a portion AA ′ according to the present invention.

First, as shown in Figure 1, a plurality of seats 100 consisting of the backrest 120 and the seat plate 110 are continuously coupled to the connection frame 130, the armrest 140 in the seat located at the left and right ends of the bench Is coupled, the upper horizontal frame 200 is coupled to the upper end of the plurality of backrest portion 120, and the lower horizontal frame 300 is coupled to the end of the seat plate 110 is shown.

2 shows a coupling state of the upper horizontal frame 200 coupled to the backrest 120 according to the present invention, and shows a coupling state of the seat plate 110 and the lower horizontal frame 300, the upper horizontal The frame 200 has a plurality of circular frame holes 220 and fixing bolts 10, and also has a plurality of circular frame holes 320 and fixing bolts 10 in the lower horizontal frame 300.

At this time, as shown in Figure 3, the lower side of the bench is provided with a reinforcing beam 410 is fastened to the lower portion of the connecting frame 130 with a fixing bolt 10, the reinforcing beam 410 is fixed bolt 10 It is shown that the supporting leg 400 is fastened to.

Here, as shown in FIG. 4, the fixing bolt 10 penetrates the through hole 211 and the coupling hole 122 formed in the connecting frame in the frame hole 210 to fix the fixing nut ( 20) are combined.

Here, as shown in Figure 5a, the fitting groove 201 formed in the upper horizontal frame 200 is fitted to the upper end of the backrest portion 100.

At this time, as shown in Figure 5b, the fitting groove 301 is formed in the lower horizontal frame 300 is fitted to the end of the seat plate 110.

Here, Figure 6 is a cross-sectional view taken along the line A-A 'shown in Figure 1, the side end portion of the seat 100 is fitted into the fitting groove 131 formed in the connecting frame 130.

Here, FIG. 7 illustrates a connection frame 400 having an elliptical shape without the fitting groove 131 as another embodiment of a cross-sectional view taken along line A-A '.

Referring to the assembly process of the present invention made of the above configuration as follows.

The connecting frame 120 is continuously fitted to the required number of seats at the side end of the seat 100, the upper horizontal frame 200 is fitted to the upper end of the backrest portion 120 formed in the seat 100, the seat plate The lower horizontal frame 300 is fitted to the end of the 110, the armrest 140 is coupled to both end seats of the bench.

At this time, the fixing bolt 10 is inserted into the frame hole 210 and penetrates the through hole 211 and the coupling hole 121 to be coupled with the fixing nut 20 fixed inside the connection frame 120. do.

Then, after the coupling is completed, the cover 220 is inserted into the frame hole 210 in the upper horizontal frame 200 and the finishing material 230 is inserted into both ends, and the lower horizontal frame 300 is frame hole 310. Insert the cover 320 and the finisher 330 is fitted at both ends.

Here, the reinforcing beam 410 and the support leg 400 provided on the lower side of the connecting frame 130 is fixed with a fixing bolt (10).

As described above, the present invention is firmly provided with an upper horizontal frame and a lower horizontal frame at the upper and lower portions of the backrest and the seat plate of the bench, and provide a small and lightweight prefabricated chair, and the upper and lower horizontals. Since the frame and the connecting frame are fixed firmly with fixing bolts and are not easily damaged, they are suitable for use in parks and rest areas, and are easy to assemble and disassemble, thereby improving convenience and efficiency.

Although the present invention has been shown and described with reference to certain preferred embodiments, the present invention is not limited to the above-described embodiments, and the general knowledge in the art to which the present invention pertains falls within the scope of the present invention.
