The present invention relates to a folding chair, and in particular, to improve the shortcomings of the pedestal installed in my own application Utility Model No. 88-11 "folding chair" that is supported in three directions and easy to fold and carry.

As shown in FIGS. 1 and 2, the pedestal installed in the first application No. 88-11 has the same configuration in which the bridge connecting piece 10 and the link connecting piece 20 are formed inside and outside, and are connected in a pair of left and right pairs. The two legs (B) (B '), which serve as the support in the folding chair (A), are connected to the left and right leg connecting pieces (10), and the lower end of the scissors link (C). When the folding operation is connected to the left and right link connecting pieces 20, the flow between each leg (B) (B ') and the link (C) left and right is limited, so the folding function is difficult and noise is generated. I had a downside.

The present invention has been devised to improve such a disadvantage, the right two legs (hereinafter referred to as "left, right support legs") and the support is connected to each of the lower ends of the link separately configured, but each The earth is constructed so that it can respond appropriately to the support, support and folding functions of the support legs and links.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

On the back, two legs (B ') (B'), which serve as supports, are erected and supported in three directions by the front left and right supports (D) (D ') and the rear supports (E), and the scissors In the folding chair which can be folded by the type | mold link (C), the back support (E) is provided in the upper part for the support leg connection (1), respectively, and the curved groove (3) is arranged side by side on the one side. And form a downward inclined surface (3 ') at both ends toward the central portion of the curved groove, and a link connecting device (2) is recommended, and a support bridge connecting device (1) and a link connecting device (2) are formed. The pin hole 4 penetrating to be formed to be formed on the side is configured to be separately installed on the support legs (B) (B ') and the lower end of both scissors link (C).

Reference numeral 5 is a connecting pin.

The present invention configured as described above has two rear supports (E) separately configured as shown in FIGS. 4 and 5, respectively, on the bottom of the right support leg (B) (B ') of the folding chair (A) and the scissors on both sides. It is installed at the lower end of the type link (C), and each of these connection configurations is fitted with the lower end of the supporting leg (B) (B ') in the supporting leg connection request (1) as shown in FIG. The lower end of the support link (B) (B ') is installed at the same time by connecting the lower end of the scissors-type link (C) in the request (2) through the pin hole (4) through the pin hole (4). Is able to flow back and forth in its connecting groove 1, and in particular above the connecting groove 2 to which the lower end of the scissors link C is connected from the curved groove 3 and its both ends. Since the inclined surface 3 'is formed downward toward the center, the front and rear flow of the link C is not restricted, so the front and rear bows of the link C It is larger in a range supporting leg and the link is connected, even if installed, as in the one component holder is not a folding operation when a bunch, it is not a concern of noise generation.

Claims (1)

Two legs (B ') serving as supporters at the rear are erected and supported in three directions by the front left and right supports (D) (D') and the rear supports (E), and the scissors In the folding chair which can be folded by the type | mold link (C), the back support (E) is provided in the upper part for the support leg connection respectively, and the curved groove (3) is arranged side by side on the one side. It forms a downwardly inclined surface (3 ') at both ends toward the central portion of the curved groove, and the link connecting device (2) is recommended, and the support leg connecting device (1) and the link connecting device (2) coincide with each other. The folding chair characterized in that the pin hole (4) penetrates so as to be formed on the side so as to be separately installed at the lower ends of the supporting legs (B) and both scissors link (C).
