Description

TECHNICAL FIELD The present invention relates to a balance training apparatus suitable for automatic training of balance sensation for persons with cerebral palsy.

BACKGROUND ART As a method for stimulating the vestibular and deep sensations that is effective as a training method for persons with cerebral palsy, for example, a swing or a seesaw,
Alternatively, there is known a method of utilizing "sway" using a therapeutic ball, a scooter board, and a hammock. A prototype of a balance training device capable of arbitrarily generating this type of shaking by mechanical force can be seen in a vehicle device for children installed in an amusement park or the like. This type of vehicle device is configured such that an animal-shaped vehicle such as a horse is supported by a pedestal, and the pedestal is driven by a swing-type lifting mechanism.

However, since this swing-type lifting mechanism uses a single motor and converts the rotational output of this motor into swing and lift of the pedestal, the swing and lift operating speeds or operating ranges are different. Can not be adjusted to. Therefore, the balance training device in which the above-described vehicle device is diverted as it is has a drawback that the training content is limited and it is difficult for the trainee to carry out a suitable balance training.

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned drawbacks, and controls the movements of the pedestal in the front-rear direction, the left-right direction, and the upper-lower direction by separate driving sources to separately determine the operating speed or operating range of the pedestal in each direction. It is an object of the present invention to provide a balance training device that can be arbitrarily variably adjusted, and can thereby effectively perform balance training for a person with cerebral palsy and a posture correction patient.

In order to achieve this object, the present invention provides a pedestal on which a trainee to whom balance training is applied by applying a forced vibration from the outside, and a lift for supporting the pedestal so that the pedestal can be raised and lowered and can be swung back and forth and left and right. A swinging mechanism, a reciprocating mechanism that reciprocally supports the lifting / lowering mechanism in the left-right direction or the front-back direction, and a reciprocating mechanism and the lifting / swinging mechanism respectively provided with lifting power. The gist is that it is composed of a swinging power and a driving force for supplying a reciprocating power.

According to this invention, the pedestal on which the trainee is placed is stacked and supported by the elevating / swinging mechanism and the front / rear or left / right reciprocating mechanism,
Since the reciprocating mechanism of these lifting / oscillating mechanisms is configured to be driven by separate driving sources, the vertical displacement of the pedestal and the lateral or longitudinal displacement of the pedestal can be controlled separately. By separately adjusting the drive timing, drive speed, drive range, etc., complex vibration modes can be set arbitrarily, which allows people with cerebral palsy or postures to sit or sleep on a pedestal. Various vibrations, which are considered to be suitable for balance training for orthodontic persons, can be easily generated and can also be applied to healthy persons. Therefore, vibrations for children's vehicles and rough horses installed in amusement parks, etc. It has an excellent effect that it can be incorporated in a generator or the like.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 are a schematic perspective view, a perspective view of a main part and a partially enlarged perspective view showing an embodiment of a balance training apparatus of the present invention, respectively.

In the case of the present embodiment, the vehicle 2a is adapted to perform reciprocating motions in the three axial directions up and down, front and rear, and left and right and swing motions around these three axial directions, for a total of six types of motion. Therefore, in addition to the main power switch 6, the start switch 7 and the stop switch 8, the control box 1a, which is a control unit for independently controlling each motion, includes six speed change switches 9 corresponding to six motions. And a sub power switch 9a for individual exercise is provided.

By the way, as shown in FIG. 2, the base 2 is supported by an elevating / swinging mechanism 3 in which a pair of links 10 and 11 intersecting in an X shape are arranged in front and rear, and one of the links 10 is supported. A connecting rod 12 is connected to a drive motor 13 via a lifting crankshaft 13a. The other end of the link 11 is pivotally supported on the front and rear of the 8-shaped frame 14 that supports the drive motor 13. At the center of the rear end of the frame 14, a crankshaft 15 for swinging the front and rear of the pedestal 2 up and down.
The drive motor 15 is connected via a, and the drive motor 16 is connected to a substantially left center of the frame 14 via a crank shaft 16a for vertically swinging the left and right of the pedestal 2. The central portion of the frame 14 is supported by a stretchable center post 17 that is planted on the base 5.

The drive motors 15 and 16 are fixed to the center and the left side of the rear end of the rectangular frame 18, respectively. Then, in the center of the front end of the frame 18, a crankshaft for driving in the front-rear direction is provided.
A drive motor 19 is connected via 19a. The drive motor 19 is fixed to another rectangular frame 20 that supports the frame 18 from below. A drive motor 21 having a crankshaft 21a for left-right driving is fixed to the left side portion of the frame 20, and the tip end portion of the crankshaft 21a is pivotally supported on the left side portion of the frame 18. Further, one end of a swing lever 22b is connected to substantially the center of the front end of the frame 20, and the other end of the swing lever 22b is a crank for swinging the front and rear of the pedestal 2 left and right. A swing motor 22 is connected via a shaft 22a. This drive motor 22 has a base 5
However, another frame 23 is interposed between the frame 20 and the base 5, and this frame 23
However, they are supported by the columns 24 that are planted at four locations on the base 5 so as to be horizontally movable.

In the balance training apparatus 1 having the above structure, the frame 14, the crankshafts 13a and 15a, the 16a, the drive motors 13 and 1
5, 16 and the like constitute the lifting / swinging mechanism 3. Also the frame
18, the crankshaft 19a, the drive motor 19 and the like configure the reciprocating mechanism 4 in the front-rear direction, and the frame 20, the crankshaft 21a, the drive motor 21 and the like configure the reciprocating mechanism 4 in the left-right direction.

Here, the six drive motors 13,15,16,19,21,22 are
In each case, the strokes of the crankshafts 13a, 15a, 16a, 19a, 21a, 22a can be variably adjusted. The variable adjustment mechanism will be described with reference to FIG. 3 by taking the drive motor 15 as an example. As shown in FIG. 3, the end portion of the crankshaft 15a is on a disc 31 attached to the output shaft 30 of the drive motor 15,
It can be positioned arbitrarily. That is, the screw shaft 32 is supported at both ends on one diameter of the disc 31, and the end of the crank 15a is pivotally supported by the nut 33 screw-fed on the screw shaft 32. Then, the tool 34 is fitted to the boss 32a having a rectangular cross section formed on one end side of the screw shaft 32, and the screw shaft 32 is normally or reversely rotated, whereby the position of the nut 33 can be arbitrarily moved. ing. Therefore, as the distance from the center of the disc 31a to the nut 33 is increased while looking at the scale plate 31a on the disc 31, the crankshaft 15a
The stroke of can be made large, and after screwing the nut 33 to the desired position, tighten the stopper thumbscrew 35 for the stopper that locks to the screw shaft 32, and fix the screw shaft 32 non-rotatably. Good.

Now, it is assumed that the trainee is placed on the vehicle 2a and the main power switch 6 is turned on and then the start switch 7 is turned on by the control box 1a. At the same time when the start switch 7 is turned on, all drive motors 13,15,16,19,
21 and 22 are energized, and rotate at the rotational speeds set by the corresponding shift switches 9. Therefore, by rotating all the drive motors 13, 15, 16, 19, 19, 21, 22 at the same time, the vehicle 2a reciprocates in the up-down, front-rear, and left-right three-axis directions, and in each of the three-axis directions. Performs a swinging motion around an axis. Therefore, the trainee on the vehicle 2a can undergo the balance training by the forced vibration given from the outside.

Here, the forced vibration given to the trainee is the shift switch 9
Can be arbitrarily changed by turning on and off, for example, the shift switch 9 of the drive motor 13 related to vertical movement (elevation).
When the power is turned off and the power supply to the drive motor 13 is stopped, the pedestal 2 stops moving up and down, and the combined operation of the other five types of operations is performed at a certain height. Since there are a number of composite actions obtained by combining the actions selected from the six types of actions, various action modes are possible. Further, even if the vertical movement position is fixed, it can be easily fixed at an arbitrary height as described below.

That is, for example, when fixing the vertical movement position of the pedestal 2,
The stop switch 8 is turned on to temporarily stop energizing all the drive motors 13, 15, 16, 19, 21, 22. next,
The sub-power switch 9a paired with the speed change switch 9 of the drive motor 13 related to the vertical movement is turned on, and only the drive motor 13 is energized. Then, when the pedestal 2 is displaced to a predetermined height position, by turning off the sub power switch 9a,
The height of the pedestal 2 can be arbitrarily adjusted within the stroke of the crankshaft 13a.

As described above, the balance training apparatus 1 is capable of various operations that combine six types of basic operations, and each drive motor
By appropriately setting the operation speeds of 13, 15, 16, 19, 21, and 22, the operation mode of the composite operation can be changed by changing the cycle of the basic operation. Furthermore, each crankshaft 13a, 15a, 16
By changing the strokes of a, 19a, 21a, 22a, it is possible to change the movement range of the pedestal 2, and the crankshaft 13a,
By stopping 15a, 16a, 19a, 21a, 22a at any position, it is possible to fix the position of the pedestal 2 in the height direction, the front-rear direction, or the left-right direction, as well as the inclination angle of the pedestal 2. Similarly, it can be fixed at any angle.

In the above embodiment, by incorporating a micro computer (not shown) in the control box 1a, the rotation speed of the drive motors 13, 15, 16, 19, 21, 22, etc.
It can be varied according to a pre-determined program, which allows, for example, normal walking in exercise training,
Accurate simulation of quick walking and driving.

Further, the vehicle 2a on the pedestal 2 is not limited to a horse shape, and may be in the shape of another animal. In addition to the animal, a vehicle such as a rocket or an airplane or a traveling object such as a train, train, or automobile may be used. It may be shaped.

As described above, according to the balance training apparatus 1, the pedestal 2 on which the trainee is placed is stacked and supported by the elevating / oscillating mechanism 3 and the front / rear or left / right reciprocating mechanism 4, and the elevating / oscillating mechanism 3 is used. Since the reciprocating mechanism 4 and the reciprocating mechanism 4 are driven by different driving sources, the vertical displacement of the pedestal 2 and the lateral or longitudinal displacement of the pedestal 2 can be controlled separately, and the drive motors 13, 19, 21 can be controlled. It is possible to set complex vibration modes arbitrarily by separately adjusting the drive timing and drive speed, etc. or the drive range of the crankshafts 13a, 19a, 21a, etc., which allows you to sit on the pedestal or sleep. Various vibrations, which are considered to be preferable for balance training of cerebral palsy persons and posture correctors, etc., can be easily generated and can be applied to healthy people as well, so it is installed in amusement parks etc. Children's vehicles and wild horses It can also be incorporated in a riding vibration generator or the like.
