Description

[Detailed explanation of the invention] [Industrial application field] The health chair of this invention can be used at home, school, office,
This is applicable to hotels, meeting places, etc.

[Conventional technology]

Conventionally, the applicant of the present application has developed and implemented a method in which a seat plate having a groove in the front-rear direction in the center is tilted slightly upward in the left-right direction and rearward direction, and a base is integrated at the center of the lower surface of the seat plate. A straight seat tool formed by the following is known. (Utility Model Registration No. 999963) [Problems that the invention attempts to solve] There are no particular problems with the above-mentioned conventional product, but
In short, this is done by correcting the posture of the upper body by correctly touching the buttocks on the seat board using the groove as a guide, and by rotating both legs backwards and hugging the base. The correct posture of the body is maintained by the autonomic balance nervous system. Therefore, for example, a person with a lordotic curvature of the spine due to a job that requires a lot of forward leaning, or a person with a lordotic curvature of the spine or a side curvature of the spine due to habit when sitting in a chair and facing a desk. etc. cannot be applied.

[Means for solving problems]

This invention has a backrest with sideboards on the left and right sides that can move up and down with respect to the underseat and maintain the desired vertical movement position.The backrest also has a cervical vertebrae, multiple parts of the vertebrae, and the boundary between the vertebrae and sacrum. A rear rod that abuts on the vicinity of the chest, abdomen, and waist is provided so as to be able to move forward and backward and maintain a desired forward and backward position, and a side rod that abuts on the left and right sides of the chest, abdomen, and waist is provided on the sideboard so that it can move forward and backward as desired. The rear rod and the side rod come into contact with the respective parts at appropriate positions, which differ depending on the height difference and whether the body is thin or obese. This allows the user to maintain correct posture for the lower back and upper body.

[Example 1] Fig. 1 is a front view, Fig. 2 is a sectional view taken along the same line as above, Fig. 3 is a plan view, and Fig. 4 is a backrest and sideboard, rear rod and side rod. FIG. 2 is a cross-sectional view showing related structures. (Note, 1st
In Figures 1 to 3, the related structures described above are omitted. ) 1 is an underseat with a footnote 1a, 2 is a backrest integrally constructed with sideboards 3 on the left and right sides, 4 is a plurality of rear rods, and 5 is a plurality of side rods. The rear rod 4 includes, in order from the top, a rod 41 for the vicinity of the boundary between the parietal bone and the occipital bone, a rod 42 for the cervical vertebrae, and a plurality of rods 4 for the vertebrae.
3. It consists of a rod 44 for the vicinity of the boundary between the spine and the sacrum, and the side rods 5 are sequentially arranged from the top: a rod 51 for the temporal region, a rod 52 for the thoracic side, a rod 53 for the abdominal side, and a rod 53 for the lumbar region. It consists of a side rod 54.

The rear rod 4, side rod 5, backrest 2, and sideboard 3 in this embodiment are constructed as shown in FIG. 4. That is, the rear rod 4 and the side rod 5 have male screws 4a and 5a.
is carved into the backrest 2 and the sideboard 3, and is screwed into a female threaded pipe 6 fixed to the outer surface of the holes 2a and 3a, and is also fitted into the holes 2a and 3a. Cushion materials 4b and 5b are fitted at the tips of both rods, and a handle 4 is fitted at the rear end.
c, 5c are fixed.

In Figures 1 and 2, 2b is a vertically moving plate formed at the bottom of the backrest 2, 1b is a hanging plate formed on the back side of the undersheet 1, 1c is a guide groove bored in the undersheet 1, and 7 is a hanging plate. A female threaded pipe fixed to a plate 2a is shown, and the vertically movable plate 2a is fitted into the guide groove 1c, and the relationship between the male thread 8 screwed into the female threaded pipe 7 and the hanging plate 1b with which the tip of the male thread 8 comes into contact. The structure is such that a desired vertical movement position is maintained.

In Figures 1 to 3, reference numeral 9 indicates an armrest having a vertically movable rod 9a at the rear of the back surface.
a is moved up and down along the support plate 10 fixed to the left and right front parts of the underseat 1, and the tip of the screw 11 screwed into the vertical movement rod 9a is moved up and down along the support plate 10.
0, the vertical movement position is maintained. Reference numeral 1d indicates a protrusion formed at the center of the upper surface of the underseat 1 and extending in the front-rear direction for indicating the center of the body.

In the configuration described above, with the rear rod 4 and the side rods 5 moved backwards, the employee sits down with his or her anus aligned with the protrusion 1d of the underseat 1, and extends both hands forward to rest on the armrest. 9 so that both sides of the chest are exposed, and then, with the body in a straight position, advance the cervical vertebrae rod 42 appropriately so that its tip can come into contact with the cervical vertebrae. The backrest 2 is raised or lowered according to the height of the employee to determine the abutting position, and the backrest 2 is fixed with the male screw 8, and the cervical rod 42 is placed against the cervical vertebrae in the correct posture. Next, the rod body 43 for the spine, the rod body 44 for the vicinity of the boundary between the spine and the sacrum, the rod body 41 for the vicinity of the boundary between the parietal bone and the occipital bone, and the rod body for the temporal region The rod 51, the chest side rod 52, the abdominal side rod 53, and the lumbar side rod 54 are advanced and come into contact with their respective parts, and the armrest 9 is moved up and down to place the arm on top of it. It is used by lightly placing the material on the surface and maintaining this state for an appropriate period of time, for example, 10 to 20 minutes.

[Embodiment 2] Fig. 5 is an explanatory diagram when the backrest 2 having the sideboard 3, the rear rod 4, and the side rod 5 are operated by a computer system. Photographs of the left and right side shapes, etc., and the positions and protrusions of the rear rod 4 and side rods 5 are input into the computer 12, and when the employee sits on the underseat 1, the side The backrest 2 with the board 3 moves up and down to an appropriate position and stops,
In addition, as the rear rod 4 and the side rods 5 move forward and backward, the pressure sensor 14 detects when pressure is applied to various parts of the body during advancement, and the prime mover 15 driven by an electric signal from the pressure moves the rear rod 4 and the side rod 5 forward and backward, as well as the appropriate degree of advancement. 16 is an AC100V power supply, 17 is a manual/automatic switch, 18 is a speed reducer,
19 is a pinion, 20 is a rack, 21 is a switch solenoid, and 22 is a power source for the solenoid.

Although two embodiments of the present invention have been described above, the present invention is not limited thereto, and the design may be modified as follows.

(a) The protrusion 1d for indicating the center of the body may be a U-shaped groove.

(b) The rear rod 4 and the side rods 5 may be configured so that they are locked by a hook means in the retreated state, and can be moved forward by a coil spring at the same time as the lock is released.

(c) The armrest 9 may be configured to be interlocked with the backrest 2.

(d) Rod body 41 for the vicinity of the boundary between the parietal bone and the occipital bone
However, the temporal region rod 51 does not necessarily require this.
