The articulated legless chair 11 according to the present invention is largely divided into an upper body support part 12 supporting a person's upper body and a lower body support part 13 supporting a lower body. The upper torso support part 12 is divided into two parts, the head support part 15 supporting the head and the waist support part 14 supporting the waist part. The lower part support part is a buttock support part 16 supporting the hip part and the knee part. It is divided into a knee support (17) supporting the calf and the calf support (18) supporting the foot portion.

Each part of the articulated legless chair 11 of the present invention is configured to be mutually refracted, and may be refracted in the form of a sitting chair as shown in FIG. 1, and as illustrated in FIG. 2A, the upper body support part 12 is referred to as a lower body support part ( It can also be used in bed form by lying down.

FIG. 2A is a perspective view of an unfolded seated chair 11 of FIG. 1 in an unfolded state, FIG. 2B is a cross sectional view from above, and FIG. 2C is a sectional view from a side.

In the following, when the person is in the form of Fig. 2A, the side where the human head is located in the longitudinal direction of the articulated legless chair 11 is called the head side direction, and the side where the human leg is located is the leg direction. This is called.

As shown in FIG. 2B, the articulated legless chair 11 of the present invention can distinguish each part of the upper body support 12 and the lower body support 13 in the longitudinal direction.

Specifically, the upper body support 12 is mainly divided into a waist support 14 for supporting the waist portion and a head support 15 for mainly supporting the head. In addition, the lower body support part 13 includes a hip support part 16 mainly supporting the buttocks, a knee support part 17 mainly supporting the upper part of the knee such as the thigh, and a calf support part 18 mainly supporting the calf and the foot. Separated by.

Looking at the length of each section of the articulated legless chair 11, the length of the knee support 17 is the shortest, next the length of the waist support 14 is short, then the calf support 18, The hip support part 16 and the head support part 15 are comprised in order.

As a preferable example of the present invention, the length of each support constituting the articulated legless chair 11 is determined as follows.

The calf support 18 corresponds to the length corresponding to the lower part of the user (the part from the tip of the toe to the back of the knee), and the knee support part 17 is the upper part of the knee (that is, the thigh). The buttock support portion 10 is a length corresponding to a hip portion or a portion including the thigh and the waist portion in the buttocks, and the waist support portion 14 corresponds to the back portion from the waist or the waist portion. The length of the head support 15 is composed of a length corresponding to the head from the head or shoulders from the back portion.

Referring to FIG. 2B, the frames constituting the skeletons of the respective support parts are installed in the articulated seated chair 11. That is, the head support frame 15a constituting the skeleton of the head support 15, the waist support 14a constituting the skeleton of the waist support 14, the hip support frame 13a constituting the skeleton of the hip support 14, the knee A hip support frame 17a constituting the skeleton of the support 17, and a calf support frame 18a constituting the skeleton of the calf support 18. The frames are preferably configured as steel pipes.

Among these frames, the head support frame 15a, the waist support frame 14a, the hip support frame 16a, and the knee support frame 17a are angle adjustments composed of ratchet-type rotating mechanisms 20a, 20b, and 20c, respectively. It is rotatably connected to each other by parts 26, 27, 28, but the calf support frame 18a is not directly connected to the knee support frame 17a and is separated from the mat member 22 filled over the frames. It is connected by the flexible urethane foam 23 and the cover member 25. Accordingly, the calf support frame 18a can be refracted at an angle of approximately 150 to 160 ° or more with respect to the knee support frame 17a, as shown in FIG. 2C.

In FIG. 2B, reference numeral 12a is an upper body support frame, 13a is a lower body support frame, 26 is a waist side angle adjuster, 27 is a head side angle adjuster, and 28 is a leg side angle adjuster.

As described above, each of the frames 14a, 15a, 16a, and 17a except for the calf support frame 18a are connected to each other via the angle adjusters 26, 27, 28, and the calf support frame 18a. After being separated from the knee support frame 17a by a predetermined distance, a mat member 22 made of an elastic material is covered up and down, and a soft urethane foam 23 is placed above the mat member 22. Then, the refractory legless chair 11 composed of the frames, the mat member and the soft urethane foam is placed in the bag-shaped cover member 25. The cover member 25 is preferably made of polyester.

Referring to FIG. 2B, referring to the relative length distribution of each support constituting the articulated legless chair 11, the knee support frame 17a is the thickness of the articulated legless chair 11 in the form of a "mattress". For example, the length of about 1.5 to 2 times the length of the 80-100mm), the waist support frame 14a is about 4 times the thickness of the articulated legless chair 11 (the knee support) About twice the length of the frame 17a). In addition, the calf support 18, the butt support 16 and the head support 15 is composed of approximately the same length, preferably about three times the length of the waist support (14).

When the articulated legless chair 11 is folded into a “compact” form, the head support 15, the waist support 14, and the buttock support 15 are bent in a c-shape as shown in FIG. 4A. The calf support 18, the knee support 16, and the hip support 15 are refracted in a c-shape to form a second refractive form. In this case, the second refraction form formed by the lower body support 13 enters into the first refraction form formed by the upper body support 12, and thus, the second refraction form may be folded as small as the length of the hip support 15.

That is, the waist support portion 14 to the knee support portion 17 are substantially upright with respect to the buttock support portion 16, and the waist support portion 14 and the knee support portion 17 are in such a shape (second refractive form). The calf support 18 can be accommodated between the head support 15 and the buttock support 16 until the tip is approximately in contact with the waist support 14.

When the articulated legless chair 11 is in the form of a "mattress", its total length is preferably about 1950 mm and its width is about 550 mm.

And cross-sectional configuration diagram in which the coupling between the teeth 224 is released.

The ratchet rotary mechanism 20 rotates the frame 221 in a counterclockwise direction so that the teeth 224 are pushed and moved each time the first toenail 212a of the ratchet 212 is pushed and moved at an angle. If the force of the spring 227 is overcome and pushed further after the full movement by 90 °, the pushing part 228 pushes the first jaw 225a of the ratchet fixing member 225 to fix the ratchet. The projection 225c is placed between the second toenails 212b and the third toenails 212c of the ratchet 212, thereby separating the first toenails 212a from the teeth 222 (FIG. 3C, FIG. 3). 3e and 3f). In this state, the frame 221 naturally rotates clockwise due to the restoring force of the spring 227, and the articulated sitting chair 11 is unfolded in the form of a bed. After the frame 221 is rotated to a position parallel to the frame 211, the pushing portion 228 pushes the third jaw 225d of the ratchet fixing member 225, thereby securing the ratchet fixing protrusion 225c. Is separated from the ratchet 212, and again the first toenail 212a of the ratchet 212 is engaged with the teeth 224.
