Description

[Detailed Description of the Invention] (Industrial Application Field) This invention uses a chair to create the same state as a handstand, and to improve the health benefits of standing on your head. This invention relates to a chair device that can be easily obtained.

(Conventional Technique) It has already been recognized that performing a traditional handstand is extremely effective for improving your health.

However, in a normal household, the reality is that even if one attempts to perform a handstand, the location and surrounding conditions are not suitable for performing the handstand. It is especially difficult for elderly people, women, and dwarfs to perform a handstand.
In general, it is not easy to perform a handstand at home.

(Problem to be solved by the invention) This invention can be used as a chair during normal times,
It is an object of the present invention to obtain a chair that can easily create the same state as a handstand by using the chair as necessary (means for solving the problem). The explanation based on this is as follows.

FIG. 1 shows an example of a plan view of the invention, and FIG. 2 shows an example of a side view of the invention.

1 is the mandrel, 2 is the frame of the seat, 3 is the board of the seat, 4
numeral 5 indicates the frame of the backrest, numeral 5 indicates the backrest plate, 6 indicates a portion of the backrest extending further downward from the point through which the shaft 1 of the frame 4 passes, and 7 indicates a part that fixes the backrest and is removable.

8 is a horizontal bar in the middle of the outer frame of the chair, 9 is an outer frame of the chair, 10 is a horizontal bar that supports the seat part, and 11 is a shoulder rest that can be moved up and down.

The mandrel 1 is made by penetrating the middle horizontal bar 8 of the outer frame, the frame 2 of the seat part, and the frame 4 of the backrest part with one mandrel. The frame 2 of the seat part and the frame 4 of the backrest part are both designed to be able to rotate around this shaft 1.

(Function) Therefore, under normal conditions, it can be used as a chair in the shape shown in Figure 2. If necessary for the purposes of the invention, the part 7 fixing the backrest can then be removed to allow the part 4 of the backrest to be moved backwards.

When the backrest part 4 is tilted backwards to a horizontal position, it rotates around the shaft 1 and becomes the position shown in Figure 3. In this case, the downwardly extending portion 6 of the backrest frame 4 is attached to the back surface of the plate 3 of the seat part, and the seat part 2 and the backrest part 4 are in a straight line.

And one corner hanging part 2 and backrest part 4 are 1 centerpiece 1
Since it rotates around , it becomes a seesaw state. A person lies on a horizontal surface. When the backrest part 4 is further lowered, it rotates about the shaft 1 and becomes in the state shown in FIG. 4 of the drawings.

In this case, the seat part 2 and the backrest part 4 can rotate about the same axis 1.

Furthermore, the part 6 which is the downward extension of the frame 4 of the backrest part is,
While densely layered on the back side of the seat plate 3, it acts to lift the seat part 2 upward together, and allows the seat part 2 and the backrest part 4 to be lowered downward while keeping the seat part 2 and the backrest part 4 in a straight line. I can do it. A person sitting down will be in a position with their head down and their legs and hips up, which is the same state as if they were doing a handstand.

The shoulder rest 11 functions to prevent the person from falling downward when the backrest portion 4 is placed downward. It can also be moved up and down and fixed according to the person's height.

In addition, when the backrest part 4 is lowered downward (Fig. 4) from the horizontal state (Fig. 3), the seat part 2 and the backrest part 4 are in a straight line as described above. Since the seat can rotate around the same axis 1 and form a seesaw state, the backrest portion 4 can be easily lowered by slightly shifting the center of gravity of the body. Also, when moving from the state shown in Figure 4 to the state shown in Figure 3, it is possible to easily return to the horizontal state by slightly shifting the center of gravity of the body in the opposite direction.

Since it is easy to operate and use, even elderly people, women, and small people can easily use it.

(Effects of the Invention) As explained above, this invention can be used as a chair in normal times, and if necessary, by removing the parts to which the backrest is fixed, the backrest can be rotated backwards. , you can easily create the same state as doing a handstand, and you can get the same health benefits as doing a handstand.

(Prior Art and its Problems) Conventionally, this type of chair has been of the seat type, and when a person is seated on the seat and leans his or her upper body against the backrest, The seat and backrest, which had an approximately oval shape, are bent into an oval shape, and the body is curved and curved. however. This type of chair has the problem that it is rarely used as a chair, and its range of use is extremely limited. Therefore, the present invention aims to provide a versatile small chair or armrest for promoting health, and it has already been recognized that performing a handstand is extremely effective for health. This is where I am. However, the reality is that even if one tries to perform handstand in a general household or '1411A, the place or surrounding situation is not suitable for performing handstand 15. It is difficult for some people to perform a handstand. Therefore, the present invention allows the small chair or the armrest to be used as a chair at all times, and allows elderly people, women, and children to use the chair as needed without easily creating the same situation as doing a handstand. The purpose is to provide a chair that can be used for The seat part J3 and the back part I are rotatably provided on a shaft member horizontally mounted on the leg part, and are configured to be linearly connected to the seat part by rotating the front rest part. This is the summary. (Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, 1 is the entire chair (in this example, the armrest is a chair); It is composed of a leg portion 2, a seat portion 11, and a backrest portion 15. Reference numeral 2 denotes the above-mentioned leg portion, and the leg portion 2 is formed mainly of a leg rod 3 framed in a left-right symmetrical shape. This leg bar 3 has an armrest member 6 suspended horizontally between the upper ends of the front and rear leg members 4 and 5, and a position at a predetermined height H of the leg members 4.5 below. In addition, a support member 7 is horizontally suspended at a position where the seat portion 11 is held horizontally. A connecting member 8 is attached to the lower part between the front leg members 4 and the lower part between the rear leg members 5 of the left and right leg bars 3 that are framed in this way, and the im part leg part 4 and the support member A reinforcing support member 9 that supports the seat portion 11 is horizontally suspended between the lower corner portions of the attachment portion 7 and the seat portion 11 . Further, a shaft member 10 that rotatably supports the seat portion 11 and the backrest portion 15 is attached at a predetermined position between the support members 7 near the rear. Reference numeral 11 denotes the above-mentioned seat part, and the seat part 11 has left and right supporting members 12 having a predetermined length, and a seat plate 13 is attached between the supporting members 12, so that the seat part 11 is arranged between the inner legs of the leg rods 3. It is formed to a width that can be rotatably housed, and the mounting of both supports is done with a shaft member 10 on the side.
A hole 14 is provided therethrough and is rotatably taken out, and the front side thereof is held horizontally by a reinforcing support member 9. 15 is the above-mentioned backrest portion;
is rotatably attached to the shaft member 10 like the seat part 11, and a backrest plate is provided in a predetermined range in the upper part of the figure between the support arm member 16 having a predetermined length' and the support arm member 16. 17 is fixedly fixed and formed to a width that can be accommodated between the inner diameters of the support member 12 of the outer part 11, and a hole 18 through which the shaft member 10 is inserted is provided at a predetermined position of the support arm member 16. , peripheral hole 18J: When the front rest portion 18 is rotated rearward in the drawings around the shaft member 10, the extension arm portion 19 extending from the circumferential hole 18J is in a horizontal position and the extension arm portion 19 is in the seat portion 11.
The front rest part 15 and the seat part 11 are connected and supported in a straight line so that they can rotate as a unit. In addition, shoulder rest members 20 are provided on the upper left and right sides of the backrest plate 17.
With this shoulder rest, the member 20 is provided so that it can be moved up and down according to the height of the user. In addition, 21 is a removably attached member near the rear of the armrest member 6. This is the backrest fixing member that has been pulled in.Next, the operation and effect of this embodiment configured as described above will be explained. 15, the seat part 11J3 and the backrest part 15 are rotatably installed on a shaft member 10 horizontally suspended on the leg part 2, and the backrest part 15 has an extension arm part 19. and configured on the extension arm. Therefore, at normal times, the armrest can be used as a normal chair by leaning the backrest part 15 against the backrest part fixing member 21 which is suspended between the members 6, as shown in FIG. Next, when using the chair 1 of this example for handstand,
When the fixing member 21 is removed, the backrest portion 15 is attached to the shaft member 10.
It is possible to rotate backwards around the center. Therefore, when the backrest portion 15 is rotated rearward and placed in a horizontal state as shown in FIG. ,
It is housed between the supporting members 12, and the backrest portion 15 and the seat portion 11 form a straight line. In this state, the user holds the armrest member 6 and aligns his or her upper body backwards, so that the user lies horizontally. When the backrest part 15 is lowered from this horizontal state, the seat part 11 is extended by the arm part 19 and is lifted upward, and the user's head is moved upward. The legs and hips should be placed upwards (see Figure 4).In this case,
Part of the human body hits the member 20 with the shoulder rest and is prevented from sliding downward. As described above, according to the chair 1 of this example, when the backrest portion 15 in FIG. 4 is lowered in the horizontal position rr4 shown in FIG. Since it covers a seesaw shape that is connected and supported by the shaft member 10 and is rotatable about the same shaft member 10, the center of gravity of the body is moved slightly toward the backrest portion 15, so that the backrest portion 15 can be easily moved. In addition, if the state shown in Fig. 3 is changed from the state shown in Fig. 4, the center of gravity of the human body is
