Description

[Detailed explanation of the invention] (a) Purpose of the invention (industrial application field) This invention relates to a chair that can be used not only as an easy chair but also as a seat when folded, and that can also be used for stretching exercises. .

(Conventional Known Technology) In the conventional chairs of this kind, the easy chair functions only as an easy chair, and the seat chair functions only as a seat chair, but there is no chair that has both functions.

(Problem to be solved by the present invention) In order to solve the problem with the present invention, the easy chair can be moved into a seated position by simply changing the locking position of the connecting rod that connects the crossed front and rear leg rods. It can be used as a chair.

(b) Structure of the present invention (means for solving problems) The vertically long U-shaped front leg rod 1 has a rising portion 2 at the upper portion and a plurality of locking holes 3 for connecting rods at the lower portion. The rear side of a U-shaped connecting rod 5 is connected to the lower part of a vertically long U-shaped rear leg rod 4 that intersects with the front leg rod so that it can be opened and closed, and the tip of the connecting rod is bent outward. Then, a locking portion 6 is formed to engage with the locking hole. Next, an oblong inverted U-shaped support rod 7 is installed on the upper surface of the front leg lever near the lower stage, and supports the tip of the rear leg lever when folded. The lower parts of the rising parts on both sides of the front leg rod are connected by connecting rods 8, the upper ends of both sides of the rear leg rod are connected by connecting rods 9, and the seat cloth 10 is stretched between both connecting rods. A chair main body is formed by attaching an inverted U-shaped backrest frame 11 to the upper stage of part 2 so that it can be expanded freely by a pivot 12, and a mat having a backrest part 13, a seat part 14, and a footrest part 15 formed in series is attached. It is.

Next, explaining another embodiment, the rear leg rod 4
A U-shaped footrest frame 17 is attached to the tip of the frame via a ratchet part 16 so that the unfolding angle can be adjusted.

(Function) As shown in FIGS. 1 and 2, when the locking portion 6 of the connecting rod 5 is engaged with the lowest hole of the locking hole 3 provided in the front leg rod, it will stand up as shown in the figure. It becomes an easy chair that rocks back and forth. When the user sits on the seat 14 and extends the backrest 13 rearward as shown in FIG. 3, the user can stretch his or her back. Also, when the connecting rod 5 and the locking hole 3 are disengaged, the leg rods 1 and 4 are folded, and the connecting rod is engaged with the upper hole 3', the lower surface of the tip of the rear leg rod is supported by the support rod 7. It becomes a seat as shown in Figure 4.

Next, in the case of another embodiment, since the unfolding angle of the footrest frame 17 is adjustable, the user can sit on the footrest 15 with the footrest 15 in the horizontal direction and stretch out his/her legs as shown in FIG.

(Example) To describe an example with reference to the drawings, reference numeral 1 is a vertically long U-shaped front leg rod, with a rising part 2 provided at the upper part, and a plurality of locking holes 3,... provided on the inner surface of the lower part, for connection as described later. By changing the engagement position of the rod, the easy chair can be used as a seat, and the inclination angle of the seat part of the seat can also be adjusted. Reference numeral 4 denotes a vertically elongated U-shaped rear leg lever that intersects with the front leg lever so as to be openable and closable. are bent 6 outward, respectively, and the bent portions are engaged with the locking holes 3. Support rods 7 are formed in an inverted U shape and are installed on the upper surfaces of both sides near the bottom of the front leg lever, and support the upper end of the rear leg lever when folded. Connecting rods 8 are installed on both sides of the lower end of the rising section, and connecting rods 9 are installed on both sides of the upper ends of the rear leg rods, a seat cloth 10 is stretched between the connecting rods, and an inverted U is installed on the upper end of the rising section. backrest frame 1
1 is pivotally extended with a pivot 12 to form the main body of the chair, which includes a backrest part 13, a seat part 14, and a footrest part 15.
A series of mats 15' are attached to the main body of the chair.

In another embodiment (FIGS. 5 and 6), a U-shaped footrest frame 17 is attached to the tip of the rear leg lever 4 via a ratchet portion 16 so as to be adjustable in angle.

(c) Effects As mentioned above, the present invention is very convenient because it allows the user to freely choose whether to use it as an easy chair or a seat. Moreover, changing from an easy chair to a seat chair is very simple, just by changing the engagement position of the connecting rod.

The fact that you can stretch your back whether you use an easy chair or a seated chair is consistent with the purpose of promoting health.
