BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic handstand which can automatically perform a handstand when a person lies on a table.

[0002]

2. Description of the Related Art Generally, humans live with their heads up and their legs down except when they sleep at night. Therefore, the flow of blood around the body is affected by gravity, and the blood that flows into the head tends to run short, making it difficult for the blood that came to the legs to return to the heart. In particular, when sports, hiking, standing work, etc. are performed for a long time, not only the legs are clogged with blood and tired, but also the legs are easily swollen. In such cases, it is said that it is sufficient to raise the legs to sleep in order to get rid of tiredness and swelling of the legs, and donut-shaped foot pillows etc. that fit on the ankles are also sold. In addition, a handstand health method that reverses the usual posture is also recommended, and the handstand pose is also important in yoga,
Emphasis is placed on the excellent effects such as activation of brain cells by facilitating blood flow to the head, and various excellent effects on various internal organs due to the reversed body position.

[0003]

However, even if the handstand is good for health, in order to carry out the handstand on its own, it is necessary to have training and substantial physical strength. Therefore, it is difficult for a person who does not exercise daily, a person who is not physically fit after illness, or a person who has a physical disability to perform a handstand on his own.

The present invention has been made in view of these problems. First, it does not require training, and a person without physical strength or a physically handicapped person can determine the degree, time, etc. of handstand. The purpose is to provide an automatic handstand that can be freely selected and can perform an appropriate handstand suitable for the person. Secondly, it is an object of the present invention to provide a suitable automatic handstand that automatically stops when the handstand reaches a predetermined position in order to avoid getting on and off and danger. Thirdly, it's easy to put on
It is an object of the present invention to provide an automatic handstand that can start a handstand immediately by lying on the handstand after foot rest.

[0005]

In order to achieve the above-mentioned object, in the automatic handstand according to the first object of the present invention, one end of the handstand on which the body is laid and which is in contact with the head side is the center of rotation of the handstand.

In the figure, 10 is an automatic handstand, 12 is a bet section thereof, and 14 is an installation section. The bed portion 12 has a rectangular flat plate-shaped upright stand 16 made of a crosspiece, a frame, a flat plate, a cushioning material and the like as a main part. Then, the handrails 18 projecting upward are installed along the left and right edges of the handstand 16. However, a handrail is not provided at the front end portion 20 in consideration of getting on and off the handstand 16.

A shaft 22 serving as a center of rotation of the upright table 16 is disposed below the front end portion 20 of the upright table 16,
A connecting member 24 in which the front ends 20 are arranged in parallel.
It is fixed to the shaft 22 via (24a, 24b). Then, the front end portion 20 and the shaft 22 are separated from each other by the connecting members 24 so as not to hinder the rotation of the handstand 16 in the forward and reverse directions, and the maximum inclination angle θ of the handstand 16 from the horizontal direction is set. It can be set to 70 degrees, for example. It should be noted that both coupling members 24 are vertically projected from the vicinity of the left and right edges of the upright table 16, and their tips are coupled near both ends of the shaft 22.

A stopper 28 is installed below the rear end 26 of the upright stand 16 so as to keep the upright stand 16 horizontally and to stop it. The stopper 28 hits the rear leg of the upright stand 16, and includes two members vertically projecting from the left and right edges of the upright stand 16 and a lateral side for connection that is hung over the tip ends of the two members. It is composed of members. It should be noted that the front leg of the handstand 16 hits both connecting members 2
It is 4 mag.

Further, the footrest 30 is installed on the upright stand 16 so as to project from the rear end thereof. This footrest 30
Is composed of a horizontal bar 32 on which the foot is hung and two left and right support bars 34 which are arranged substantially in parallel with each other so as to hang and support the foot hang bar 32 between the front end portions. Then, the base end portions of the left and right support rods 34 are fixed near the left and right edge portions of the upright table 16, and the respective support rods 34 are held downward and rearward, for example, inclined by 60 degrees from the horizontal direction and held. It should be noted that if a recess is formed on the upper surface of the upright table 16 near the rear end portion 26 to allow the buttocks to lie, it will be easier to lie on the upright table 16 and will be stable, so that it will not easily slip even when it is upright.

The mounting portion 14 has a rectangular flat plate-shaped mounting base 36 including a crosspiece, a frame and a flat plate as a main part. Then, the shaft 2 of the upright stand 16 is attached to the center of the upper surface of the stand 36.
2 is provided with a shaft drive device 38 for giving a driving force for rotation and a shaft control device 40 with an operating device for giving the shaft drive device 38 a signal for controlling the rotation direction, rotation and stop of the shaft 22. The shaft drive device 38 includes a DC motor 42, a reduction gear train 44, and the like. Then, the power generated in the DC motor 42 is fixed to the shaft 46 of the DC motor 42,
It is transmitted to the pulley 52 via the belt 50 and is transmitted to the shaft 56 of the small diameter gear 54 at the rear end of the reduction gear train 44. Next, the power is gradually reduced through four combined gears 64 having a large-diameter gear 60 and a small-diameter gear 62 on the shaft 58 and one having a large-diameter gear 68 on the shaft 66. Radial gear 70
To the shaft 22 via.

In this way, when the rotation speed of the motor 42 is reduced and transmitted to the shaft 22 of the upright table 16, even if the rotation speed of the motor 42 is, for example, 1800 rotations / minute, the rotation speed of the shaft 22 is reduced to 1 The tilt angle (position) of the upright table 16 can be slowly changed by rotating / minute. Therefore, it takes about 12 seconds for the stand 16 to rotate from the horizontal position to the maximum tilt angle of 70 degrees. All of these shafts 56, 58, 66 and the like are left and right vertical side plates 72 (72a, 7a) fixed to the central portion of the upper surface of the mounting base 36.
2b) and rotatably support it. Also, shaft 2
The reference numeral 2 is rotatably supported by being hung on vertical side plates 74 (74a, 74b) fixed to the left and right edges of the upper surface of the mounting base 36 and also corresponding to columns. In the reduction gear train 44, from the small diameter gear 54 to the adjacent large diameter gear 60, the small diameter gear 6 is further added.
Power is transmitted from the small diameter gear to the large diameter gear in sequence from 2 to the adjacent large diameter gear.

Further, a main part including a control circuit and the like of the shaft control device 40 is installed near the pulley 52. Then, the main part thereof is connected to an operating device for controlling the upright table 16 and first and second limit switches 76 and 78 for detecting that the upright table 16 has reached a predetermined position. The operating device 80 is provided with stop, up, and down push buttons 82, 84, as shown in FIG.
The switch 86 is provided at an arbitrary position such as the upper surface of the handstand 16 so that the operator can hold the operator 80 and lie down. Alternatively, after the body is laid down, the handrail 18 is grasped by one hand and fixed to the front end portion or the like of the right handrail 18 so that the other hand can be easily operated.
Further, the first limit switch 76 is a horizontal position detector, and is installed near the left rear end portion of the mounting table 36 in order to detect that the upright table 16 has reached the horizontal position and issue a stop signal. Then, it is operated by the stopper 28 of the upright table 16. Also, the second limit switch 78
Is a maximum tilt position detector, which detects that the inverted stand 16 has reached the maximum tilt position (angle) set and issues a stop signal.
Install in the vicinity of. Then, it is operated by the right connecting member 24b.

In such an upright machine 10, since the upright stand 16 on which the body is laid rotates in the forward direction about the shaft 22 and rises, or rotates in the opposite direction and descends, it is prevented from falling sideways. You have to secure safety. Therefore, as a fall prevention device 88 for the mounting base 36, a cylindrical crosspiece 90 is installed at the front end portion of the mounting base 36, and the rod-shaped members 92 (92a, 92b) are housed inside and can be pulled out to the left and right respectively. To use. Furthermore, when a screw (not shown) is attached to the tip of these drawer members 92,
Each of the drawer members 92 is screwed to the floor so that the handstand 10
It is possible to prevent rattling due to left and right swings. Further, the vicinity of the reduction gear train 44 and the like is covered with a cover, and a safety net is attached around the lower side of the upright stand 16 so that limbs and the like can be supported.
Do not enter underneath. Furthermore, a mat (not shown) is laid on the floor so as to partially cover the tip of the mounting table 36 to ensure safety. The mounting table 36
A caster (not shown) for moving the handstand 10 may be attached under the.

When in use, ride on the handstand 16 and
As shown in, the front side of both ankles is hung on the horizontal bar 32 of the footrest 30 and the body is laid down. Then
You can easily rest your legs, and when you lie down, both knees stand upright.
It comes near the rear end and the head comes to the front end 20. Then, when the up button 84 of the operation unit 80 is pressed, the motor 4
2 starts and starts rotating in the forward direction. Then, the power is immediately transmitted to the shaft 22, and the upright stand 16 starts to rotate in the forward direction around the shaft 22, the rear end side largely rises, the front end side slightly descends, and the inclination angle of the upright stand 16 gradually increases. Go. At that time, since the leg 94 is bent from the leg 96 and the ankle thereof is hung on the horizontal bar 32, and the leg 96 is further bent to hang the rear side of the knee near the rear end of the handstand 16, the rear end of the handstand 16 The body is well fixed in the vicinity of the part so that it does not easily slip off, and the body naturally enters an upright state with the inclination of the handstand 16. Therefore, even a person who does not exercise everyday, a person who is not physically fit after illness, or a person who has a physical disability and who has difficulty performing handstand on his / her own can easily carry out the handstand.

Then, when the handstand 16 reaches an inclination angle suitable for its physical condition, that is, the degree of handstand, the stop button 82 is pushed. Then, the handstand can be continued while maintaining the degree of the handstand. When the down button 86 is pressed after standing up for a necessary time, the motor 42 starts rotating in the opposite direction this time, and the rear end side of the upright stand 16 largely descends,
The front end side slightly rises and the inclination angle of the handstand 16 gradually decreases. Naturally, when the stop button 82 is pushed even during the descending, the erecting stand 16 can be held at the inclination angle during the descending and the erecting can be continued. Therefore, an appropriate handstand can be performed by freely selecting the degree and time of handstand.

If the stop button 82 is not pressed when the upright table 16 is raised by increasing the tilt angle, the tilt angle increases, but when the set maximum tilt angle of 70 degrees is reached, the second tilt angle is increased. The limit switch 78 detects the position. Therefore, it is possible to automatically stop the handstand 16 at that position and avoid the risk of the body slipping off. Further, if the stop button 82 is not pressed when the upright table 16 is lowered due to the decrease in the tilt angle, the tilt angle becomes smaller, and when the horizontal position, that is, the tilt angle reaches 0 degree,
The first limit switch 76 detects its position. Therefore, the handstand 16 can be automatically stopped at the horizontal position to facilitate getting on and off.

In the above-described embodiment, since the body is laid on the upright stand 16 with the body facing upward, the support bars 34 of the footrest 30 installed at the rear end of the upright stand 16 are held in a downwardly inclined rearward direction. I explained about the case,
When lying down with the body facing downward, each support rod of such a foot hanger may be held by tilting it upward and rearward. In the latter case, the horizontal bar of the footrest should be hung around the back of the ankle. The foot hanger may be rotatable about an axis so that it can be appropriately fixed at a required inclination angle.

In the above embodiment, the shaft drive unit 38 is composed of the DC motor 42, the reduction gear train 44, etc., but the shaft drive unit is a combination of a hydraulic pump with a DC motor and a single power cylinder. Alternatively, the piston rod may be made to project by pushing out the oil by driving the direct current motor to raise the upright stand, and the return of the oil due to its own weight of the upright stand or the like may be used to lower the upstand stand. By the way, since the hydraulic pump has a built-in relief valve, it is possible to stop the handstand by freely selecting its inclination angle when the handstand is raised and lowered.
