2. Description of the Related Art Among exercise load devices, for example, a treadmill is a medical / training load device for walking load.
It is widely used as a medical examination device, a rehabilitation device, or an exercise device in hospitals, schools, athletic facilities, research laboratories, and the like. Conventionally, treadmills that are widely used are only one-dimensional loads for walking on a constant plane, or for example,
Only by applying a two-dimensional load on a surface that can be tilted in the front-rear direction as shown in Japanese Utility Model Publication No. 7-17322, a load is applied on a three-dimensional surface that is tilted in the front-rear and left-right directions, such as when walking the human body. Movement and motor skills have not yet been analyzed and quantified.

Also, for example, a road surface frame supporting a belt as a road surface is supported by a ball bearing so as to be three-dimensionally swingable, and is driven by two inclined cylinders (Japanese Patent Application Laid-Open No. H9-1990). No. 233364), or a balance training device in which the pedestal can swing back and forth and left and right by independently driving the first drive source to the sixth drive source (Japanese Patent Publication No. 6-6530). Has been
These are complicated, require a plurality of motor control mechanisms separately, are expensive, and themselves constitute a treadmill or balance training device. Absent.

Recently, in the diagnosis or rehabilitation of diseases,
Diagnostic methods have been proposed to accurately grasp the physical characteristics of a patient by applying various three-dimensional loads to the patient, collecting the data, and analyzing and quantifying the data. However, none of these medical and training load devices can apply a three-dimensional load, and is not satisfactory in terms of structure, control, cost, etc., which is a factor that hinders its spread.

[0005]

At present, treadmills with one-dimensional or two-dimensional loads and various types of exercise loads for medical and training use have become widespread. Introducing a loadable medical / training exercise load device has a problem that a more expensive device must be newly introduced in place of the existing medical / training exercise load device. Conventionally, as described above, a single-structured exercise load device capable of three-dimensional loading has been proposed, but a currently popular one-dimensional or two-dimensional load type exercise load device is changed to a three-dimensional load type as it is. There is no technical idea to do so, and no technical means have been proposed.

The present invention has been made in view of the above circumstances, and can be easily applied to an existing one-dimensional or two-dimensional load type treadmill or other medical / training exercise load device. A tilting platform for exercise load devices that can easily and inexpensively convert a load device to a two-dimensional load type or a three-dimensional load type, has a simple structure, is inexpensive, and can statically and dynamically tilt two-dimensionally or three-dimensionally. It is intended to provide a device.

According to the present invention, there is provided a tilting table for an exercise load device which achieves the above object, a fixed frame, a tilting table supported so as to be tiltable about one axis with respect to the fixed frame, and a tilting table. And a mounting device provided on the inclined table so as to mount and fix the medical / training load device thereon, and a single actuator that inclines and holds the inclined table at an arbitrary angle. Thus, the conventional one-dimensional exercise load device can be easily converted to a two-dimensional exercise load device, and the two-dimensional exercise load device can be easily converted to a three-dimensional exercise load device.

[0008] Further, the tilting table for an exercise load device of the present invention, which is capable of converting a conventional one-dimensional exercise load device to a three-dimensional exercise load device, has a tiltable tilt drive in the front-rear direction (X-axis direction). An X-axis tilting table assembly having a table, and a Y-axis tilting table assembly having a tilting table that can be driven to tilt in the left-right direction (Y-axis direction).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a three-dimensional tilt table apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings. 1 to 3 show the overall configuration of a three-dimensional tilt table apparatus according to an embodiment of the present invention, and FIG. 4 shows a state in which a treadmill is mounted on the three-dimensional tilt table apparatus.

The three-dimensional inclined table apparatus 1 of the present embodiment comprises a lower table assembly 2 and an upper table assembly 3 each having a single-axis swingable tilt table. The upper base assembly 3 is detachably fixed, and the upper base assembly 3
As shown in FIG. 4, an existing treadmill 4 and the like can be removably mounted and fixed on the inclined table.

[0012] The three-dimensional tilting table apparatus of the present embodiment is used to move the traveling direction of the running vector of the treadmill mounted thereon,
That is, FIG. 1 shows a state viewed from the front-back direction (hereinafter referred to as X direction).
2 and FIG. 3 shows a state viewed from the right and left direction (hereinafter, referred to as a Y-axis direction) orthogonal to the direction. In the present embodiment, the tilt base of the lower base assembly 2 is the X-axis tilt base 5 provided to be swingable in the X-axis direction, and the tilt base of the upper base assembly 3 is provided to be swingable in the Y-axis direction. Y-axis tilt table 6
It has become.

The lower base assembly 2 has a rectangular parallelepiped fixed frame 7, and a pair of shaft support plates 8 for connecting the upper frame and the lower frame are fixed to the center of the lower base assembly in the longitudinal direction. An X rotation shaft 10 is rotatably supported on a bearing 9 fixed to the support plate 8. A pair of brackets 12 are fixed to a central portion in the longitudinal direction of the X-axis tilt table 5 supported by the X rotation shaft 10 as shown in an enlarged view in FIG. Are keyed and fixed to the X rotation shaft 10. Therefore, the X-axis tilting table 5 rotates integrally with the X-rotation axis 10 when the X-rotation axis 10 rotates at a predetermined angle (usually within ± 10 ° from the horizontal plane) with respect to the fixed frame, and the tilt angle can be arbitrarily changed. I have. In FIG. 1, reference numerals 13 and 13 denote stoppers that regulate the maximum tilt angle of the X rotation axis, and are provided near both ends of the fixed frame in the X axis direction. However, the stopper 13 is not always required.

On the other hand, although the size of the upper base assembly 3 is slightly smaller than that of the lower base assembly 2, the structure thereof is almost the same as that of the lower base assembly except that the inclination direction is different. That is, the upper base assembly 3
Is the Y rotation axis 1 perpendicular to the X rotation axis 10 of the lower base assembly.
1, the Y-axis tilt table 6 is fixed to the Y-rotation axis, and the Y-rotation axis 11 is driven to rotate so that the Y-axis tilt table 6 is tilted at a predetermined angle in the Y-axis direction. It has become.

Since the tilt mechanism of the X-axis tilt table 5 and the Y-axis tilt table 6 are the same, the tilt mechanism of the Y-axis tilt table 6 shown in FIGS. 8 to 9 will be described. Are denoted by the same reference numerals, and description thereof is omitted.

A lever 15 is keyed at an appropriate position of the Y rotation shaft 11 (in this embodiment, near one shaft end), and is fixed to the rotation shaft. Drive rod 17 of a linear actuator 16 such as a linear motor, an electric cylinder, or a hydraulic / pneumatic cylinder having a power mechanism (position holding mechanism) capable of holding a position.
Are connected. As shown in FIG. 9, the linear motion actuator 16 includes a base 18 provided on a lower frame of the fixed frame.
Is supported via a shaft 20 so as to be swingable. The tip of the drive rod and the lower end of the lever 15 are also pivotally fixed to each other.

Accordingly, when the linear motion actuator 16 is driven to move the drive rod 17 by a predetermined stroke, the lever 1 is moved by an angle corresponding to the stroke.
5 is swung, and as a result, the Y rotation axis also rotates, and the Y-axis tilting table 6 fixed thereto is tilted by a predetermined angle. that time,
The linear actuator is pivoted on the shaft 20 and the lever 1
5 can swing about the Y-rotation axis 11, respectively, so that the linear motion of the drive rod 17 by the linear motion actuator 16 can be smoothly converted to the tilt motion of the Y-axis tilting table, and the linear motion after the stop. As long as the dynamic actuator acts as a brake and the linear actuator is not driven, the Y-axis tilt table 6 can continue to maintain its angle.

Therefore, the Y-axis tilt table is supported by only one axis, and can be maintained at an arbitrary predetermined angle without requiring a special brake mechanism or an angle holding mechanism or a plurality of actuators. Therefore, the structure is very simple, and the manufacturing cost can be reduced. With a similar mechanism, the X-axis tilt table 5 can also be tilted at an arbitrary angle independently of the Y-axis tilt table.

Stoppers are provided on the X-axis tilt table 5 for mounting and fixing the upper table assembly 3 and on the Y-axis tilt table 6 for mounting and fixing the treadmill 4 and the like. .
The stopper is arbitrarily adjustable according to the size of the treadmill to be mounted thereon, so that existing treadmills having different sizes can be easily mounted and fixed. FIG. 10 shows an embodiment of the stopper. The stopper 25 of the present embodiment comprises an angle-shaped metal fitting having a rising wall 28 on one side of a bottom wall 27 in which a long groove 26 is formed, and an inclined metal fitting. It consists of bolts 29 that are fixed to the table. As shown in FIGS. 5 and 6, a plurality of the stoppers are installed near the periphery of the inclined table, and are displaced such that the rising wall 28 abuts on the fixed frame of the upper stand assembly or the treadmill mounted thereon. Then, by tightening the fixing bolt at that position, the object placed thereon can be fixed.

The stopper 25 may serve as a stopper so that the object mounted on the X-axis inclined table or the Y-axis inclined table does not slide down due to the inclination. It is only necessary to move the upright wall 28 by hand until it comes into contact with the upper frame assembly or the fixing frame 7 of the treadmill at the time of mounting, and tighten and fix the bolt 29 at that position. An ornament can be attached. In addition, since the size of the conventional treadmill is almost constant, if the adjusting range of the stopper can be moved by about 25 cm, practically there is almost no problem, but the moving range may be selected as necessary.

The three-dimensional inclined table apparatus 1 of the present embodiment is configured as described above, and as shown in FIGS. 1 to 3, the upper table assembly 3 is mounted on the X-axis inclined table 5 of the lower table assembly 1. By appropriately contacting and fixing the rising walls 28 of the stoppers 25 to the four sides of the fixed frame, the upper base assembly 3 is driven to tilt around the X axis. Also, as shown in FIG. 4, an existing treadmill 4 is attached and fixed on the Y-axis inclined table 6 of the upper table assembly 3 in the same manner. Therefore, the treadmill 4 can be arbitrarily tilted independently around the Y axis and the X axis,
The tread surface can be tilted to any three-dimensional position.

Further, the three-dimensional tilting table apparatus of the present embodiment is configured by separately and independently drivably superimposing two tables, a table tilting back and forth and a table tilting left and right. Since the three-dimensional tilt can be realized by two actuators and asynchronously by operating them separately or simultaneously, the structure is very simple, and a complicated control mechanism for tilting in three axes is not required. Can be provided at low cost. Moreover, according to the three-dimensional tilting table apparatus of the present invention, an existing treadmill that has already been introduced can be easily mounted, and an existing treadmill that can only perform one-dimensional load or two-dimensional load can be replaced with an extremely treadmill. It can be converted to a three-dimensional load treadmill at very low cost.

In addition to the load in the static state in which each of the tilt tables is held at a desired angle, the two actuators can be driven separately and continuously.
Since the X-axis tilt table and the Y-axis tilt table swing independently, Y
A treadmill or other object placed on a shaft tilt table can be moved very complicatedly, making it possible to perform inspections and training under complicated dynamic load conditions that could not be done with conventional treadmills etc. Become. Thereby, for example, the treadmill, which could only be diagnosed by walking analysis on a flat surface or an inclined surface in the X-axis direction in the past, can be changed in the front, rear, left, and right directions to perform walking analysis in a static state or a dynamic state, By quantifying the result, it is possible to diagnose the disease.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various design changes can be made within the scope of the technical idea. For example, in the above embodiment, the lower base assembly has the X-axis tilt base and the upper base assembly has the Y-axis tilt base. However, the reverse is also possible. In addition, since the lower base assembly and the upper base assembly of the present invention can be freely separated, they can be used alone as a tilting table apparatus for an exercise load device. For example, when converting a conventional one-dimensional exercise load device to a two-dimensional exercise load device, if a tilt in the front-rear direction is required, a lower base assembly having an X-axis tilt base is used alone, When the tilt in the direction is required, the upper base assembly having the Y-axis tilt base may be used alone. Similarly, when converting a conventional two-dimensional exercise load device to a three-dimensional exercise load device,
What is necessary is just to select one having an insufficient axially inclined table.

Further, the tilt drive mechanism of the tilt table is preferably a linear motion actuator as in the above embodiment. However, the present invention is not limited to this. For example, a gear is fixed to a rotating shaft and the gear is directly driven by an output gear of a motor. It is also possible to do so. In addition, the exercise load device to be mounted on the tilting table device of the present invention is not limited to a treadmill, and various exercise load devices used for diagnosis, rehabilitation, body training, and athletic can be mounted. it can.

[0026]

As described above, according to the tilting table device for exercise load device of the present invention, the conventionally introduced one-dimensional or two-dimensional exercise load device can be easily and inexpensively converted to two-dimensional or tertiary one-dimensional exercise load device by a simple mechanism. The original exercise load can be converted into a medical / training exercise load device.

In particular, the X-axis tilt table and the Y-axis tilt table can be tilted and driven only by a single actuator, respectively, and do not require a special holding mechanism such as a brake mechanism, so that the structure is very simple. Since the X-axis tilt table and the Y-axis tilt table can be tilted independently and freely, no special control mechanism is required and the control mechanism is very simple. It is possible to obtain an inexpensive tilt table device for an exercise load device capable of performing a primary load. In addition, by providing an adjustable stopper on the inclined base, it can be easily mounted regardless of the type of exercise load device such as a treadmill that has already been introduced.
