Description

[Detailed explanation of the idea]

【0001】

[Industrial Application Field] The present invention relates to a lightweight folding all-purpose chair.

【0002】

[Prior Art] Conventionally, for this type of product,
It looks like the following. 1. Bath chairs are made for use in washing areas, showers, etc. with wheels or a backrest. 2. Those used for toilets and urinals are chair-shaped and have a container underneath to catch waste. Others are made of plastic and are designed to be fixed to a conventional toilet bowl for the purpose of heightening the toilet bowl. 3. General chairs and folding pipe chairs are made for the purpose of sitting.

【0003】

[Problems to be solved by the invention] The conventional techniques described in the prior art had the following problems. 1. Because they are made for individual purposes such as baths, toilets, and indoor use, it would be expensive and uneconomical for elderly people and people with physical disabilities to purchase products that fit their bodies by purpose. 2. Conventional chairs with fixed standards place a great burden on people with ankle, knee, and hip problems (arthritis, rheumatoid arthritis) when bending and stretching their bodies. 3. Due to differences in individual heights and disabilities, it is not possible to easily adjust the height etc. to suit each person's body.

[0004] The present application was made in view of such problems with the conventional technology, and its purpose is to provide something that can do the following. Due to differences in individual heights and disabilities, the objective is to provide a device that can easily adjust the height, etc., to suit each person's body at different times.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows. That is, the present invention is a lightweight folding universal chair in which a toilet seat part 3 is disposed within a frame 2 having a U-shape in plan, and the frame 2 and toilet seat part 3 are configured to be freely bendable in the vertical direction from the center. be.

[Example] An example will be described with reference to the drawings. 1 is a lightweight folding universal chair of the present invention, which is composed of a frame 2 and a toilet seat part 3. The frame 2 consists of left and right frame units 4 and 5 that are symmetrically constructed. Therefore, the left frame single body 4 is the left front and rear frame 4A.
A front leg 4B and a rear leg 4C are connected downward to the front and rear ends of the left front and rear frames, and a reinforcing frame 4D is stretched parallel to the left front and rear frame in the upper part between these front and rear legs. and a left upper connecting arm 4 rotatably connected to the rear end of the left front and rear frame 4A toward the right.
It is composed of E. In addition, the right frame unit 5 includes a right front and rear frame 5A,
A front leg 5B and a rear leg 5C are connected downward to the front and rear ends of the right front and rear frames, and a reinforcing frame 5D is stretched parallel to the right front and rear frame in the upper part between these front and rear legs. It is comprised of a right upper connecting arm 5E rotatably connected to the rear end of the right front and rear frame 5A toward the left. The tip of the left upper connecting arm 4E of the left frame unit 4 and the tip of the right upper connecting arm 5E of the right frame unit 5 are connected to the vertical operation plate 2A with a longitudinal pin 2A1, and both They are connected by a coil spring 2B that acts inward.

[0007] Below the vertical operation plate 2A, a support shaft 2A2 is protruded in parallel with the reinforcement frame 4D with the support height of the reinforcement frame 4D, and left and right shafts rotatably connected to the support shaft 2A2 are provided. The tips of the undulating rods 4F and 5F are rotatably connected to the reinforcing frames 4D and 5D, respectively. In addition, a vertical hole 2A3 is formed in the center of the vertical operation panel 2A, and left and right diagonal undulating rods 4G and 5G are rotatably connected to a pin 2A4 that is loosely fitted in the vertical hole 2A3 so that it can be raised and lowered. The distal end is rotatably connected to the rear leg 4C and the rear leg 5C at the support height of the reinforcing frame 4D. 2A5 is a handle installed on the top of the vertical operation plate 2A. Right and left toilet seat supports 4H and 5H are provided inwardly protruding near the tips of the reinforcing frame 4D and the reinforcing frame 5D, respectively.

[0008] The toilet seat portion 3 has a horseshoe-shaped planar shape as a whole like a known toilet seat, but consists of left and right toilet seat units 6 and 7 that are symmetrically divided from the center. Therefore, the root portion of the left toilet seat unit 6 is rotatably connected to the left undulating rod 4F, and the tip portion is configured to abut the left toilet seat support 4H from above. In addition, the base of the single toilet seat 7 on the right is the 5th floor of the right undulating rod.
It is rotatably connected to the toilet seat holder 5H, and its tip is configured to abut the right toilet seat support 5H from above. 6A and 7A are reinforcing rods suspended between the toilet seat and the undulating rod. The heights of the front legs 4B and the rear legs 4C, and the front legs 5B and the rear legs 5C are adjustable as shown in FIG. That is, to explain this adjustment mechanism 4I using the front leg 4B as an example, in the lower pipe part 4B2 and the upper rod part 4B3 fitted into the lower pipe part 4B2 so as to be able to move up and down, an appropriate number of adjustment holes are formed in the upper rod part 4B3. 4B4, and on the other hand, a pin 4B5 and a pressing bolt 4B inserted into the adjustment hole 4B4 are inserted into the lower pipe part 4B2.
6 is installed. 4B1 is a suction cup provided at the lower end of the front leg 4B, 5B1
is a suction cup provided at the lower end of the front leg 5B, 4C1 is a disc-shaped plate provided at the lower end of the rear leg 4C, and 5C1 is a disc-shaped plate provided at the lower end of the rear leg 5C.

[0008] The invention works as follows. 1. Referring to FIG. 3, when the handle 2A5 is supported and pulled upward, it will be folded as shown in FIG. 2 In the folded state as shown in Figure 2, if you support the handle 2A5 and push it down, it will open as shown in Figure 1.
It becomes ready for use as shown below. 3 In the state shown in Figure 1, the left and right toilet seats 6, 7
can be made undulating as shown in FIG.

【0010】

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects. 1 The folding mechanism is mounted on the backrest, so
Can deal with the environment under the seat. 2. Place a plate-shaped cushion with a core on top of the toilet seat and use it as a conventional chair. 3. The user can fold it with one hand while standing. As a result, 4. It can be used for both Western-style and Japanese-style toilets, bathrooms, indoors, and outdoor rest areas. 5. As mentioned above, it can be easily folded up and down with one hand, and can be carried around when going out or carried in a passenger car, and can also be used in Japanese-style public toilets and train toilets. 6.As we move towards an aging society, this is a chair that can be used for multiple purposes and kept close at hand like a walking stick.
