Abstract

PROBLEM TO BE SOLVED: To attain an ideal body center of gravity balance by supporting a waist mounting base section tiltably in all directions, naturally dropping it with only the body weight of a patient, and making the drop width and the elevation angle of a back mounting base variable or fixable. SOLUTION: A pressure receiving plate 19 is inclined by a posture changing pneumatic cylinder 21 to set a waist mounting base 2 to the inclination suitable for correction. The elevation angle of a back mounting base section is adjusted so that a drop shock is accurately applied to the bone portion to be corrected. The receiving tool 24 of a natural drop mechanism is moved to the position where the required drop size is obtained by the belt 27 of a drive source 26. The air in the pneumatic cylinder 20 is discharged at once, and the waist mounting base 2 is naturally dropped in the inclined posture together with a patient and a support frame 18. When the waist mounting base 2 is dropped by the prescribed size and is received by the receiving tool 24, a shock is applied to the patient. The balance of the whole body and health can be recovered by this constitution.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of correcting the pelvis, iliac and sacrum of a human body to achieve ideal recovery of the center of gravity of the body, and to correct the position of the center of gravity of the body for the purpose of balancing the center of gravity of the body and recovering health. For beds.

[0002]

2. Description of the Related Art Hitherto, as a bed for correcting the position of the center of gravity of the body, a bed for correcting the sacrum has been proposed, and has been commercialized and marketed. In this conventional product, the lumbar support base for supporting the pelvis portion has two left and right sides.
It is configured so that it can be tilted only in the direction, and the human body is fixed horizontally at least above the waist, and the width of natural fall is also fixed at 15 mm, so only the sacrum and iliac The joints, that is, the sacrum, as a single bone, could be corrected as a single bone, and only the first and second parts could be corrected as desired observations. See Japanese Patent Application Laid-Open No. 3-184664). In other words, as a result, only the linear portion of the spine of the sacrum, which is an extension of the vertebra, is regarded as an object of treatment.

Due to the structure of the human body, the weight of the upper body is
As shown in (A), it has been found that the sacrum S is located at the center of the pelvis K and has a base of an inverted triangular sacrum S. The reaction force from the foot supporting the weight also acts on the isosceles triangle of the sacrum from the femur D through the hip joint M. That is, all the emphasis points of the body weight are on the sacrum S. However, as shown in FIG. 15A, the sacrum S has a spherical shape with a lordosis, and the position of the center of gravity of the sacrum is located near the center of the sphere. When the human body is viewed from the side, as shown in FIG. 14 (B) or FIG. 16 (A), the center L of the head (skull), the center of the sacral frontal sphere, and the ankle of the foot are on a straight line L which is vertical. When you are above your body, you are ideally balanced.

If the position of the center of gravity deviates from the original ideal position of the center of gravity, it affects the curvature of the spine based on the sacrum S, as shown in FIGS. 16 (B) to 16 (D). It can cause physical balance and impair health. In addition, as shown in FIG.
K, that is, 1st to 5th in order from the spine to the coccyx, and especially the 3rd to 5th and coccyx B greatly affect not only the physical surface but also the mental surface. It turns out to be a very important part. FIG. 16 (A)
The state shown in (1) is when the body is ideally balanced.

[0005]

The above-described conventional sacral correction bed is manufactured without performing the above detailed analysis of the body structure. Because only the first and second parts of the sacrum could be corrected, the lower SK of the sacrum S (No. 3 to 5), which greatly affects not only the physical surface but also the mental surface of the human body
Correction of the site over coccyx B was not possible. Since all normal vertebrae, including the sacrum, are moving infinitely infinitely, a means of recovering this infinite movement is desired.

Therefore, the present invention was devised as a result of various studies in order to solve the drawbacks of the conventional means, and it was proposed that the pelvis, iliac and sacrum, especially the lower part of the sacrum (No. 3 to 5) be used.
It is an object of the present invention to achieve the ideal recovery of the position of the center of gravity of the body by also correcting the portion ranging from No. 1 to the tail bone, and to achieve the ideal balance of the center of gravity of the body.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a lumbar support table which can be tilted in at least three or more arbitrary directions. Although the platform falls naturally only with the patient's weight, the width of the fall can be changed, and the elevation angle of the backrest can be changed and fixed freely.Specifically, the waist The mounting table is supported by the support frame so as to be tiltable in all directions with respect to a horizontal plane, and a posture changing mechanism and a posture returning mechanism of the waist mounting table are disposed on the support frame. The posture changing mechanism is located below the waist placing base and pushes up the waist placing base only at the time of the pushing-up operation, and the lower side of the waist placing base is turned downward on the side opposite to the pushed-up portion. To maintain the tilted posture, and Mechanism, the time was pushed up operating below the waist mounting base part only contacts the 置用 stand part this lumbar mounting serves to return the posture to its original horizontal position,
The support frame is supported via a natural drop mechanism, and the back mounting base is configured to be capable of changing and fixing an elevation angle.

[0008] According to this means, the waist placing table is supported by the support frame so that it can be inclined in all directions.
Since the inclination direction can be freely changed via the posture changing mechanism, the inclination direction can be changed only in two directions. Therefore, the conventional sacrum is effective when the inclination is roughly corrected as a single bone. Unlike the means, even if the inclination of the sacrum is in any direction, the direction to be corrected can be accurately displayed in correspondence with this.

[0009] In addition, the size of the natural drop of the waist placing table can be freely adjusted and changed, so that the impact of the natural fall is large and small, unlike the conventional means in which the fall width of the natural fall is constant. Can be adjusted. Therefore, an ideal impact can be given according to each symptom regardless of severe or mild.

The elevation angle of the back mounting table can be freely changed, so that the first to fifth sacral sacral vertebrae and the coccyx, as well as the pelvis,
The impact of natural fall in the correct direction can be properly applied to each part of the iliac bone. In other words, it is possible to accurately apply a drop impact to a desired location corresponding to the sphere from the sacrum to the tailbone.

Therefore, the present invention has the following effects. Including the sacral vertebrae of the sacrum requiring treatment, the tailbone, iliac bone,
In addition, the pelvis can be accurately grasped, and the lumbar mounting base can be freely tilted in the correction direction according to the misalignment regardless of the direction of the misalignment. Optimal impact can be given according to the symptoms up to the basic side,
The iliac and even the pelvis, not to mention the lower sacrum (3rd
From the sacral vertebra to the 5th sacral vertebra), the tail bone can be corrected accurately. Therefore, the balance of the center of gravity of the body is shown in FIGS.
Further, the head (skull) as shown in FIG.
The center of the anterior sacrum, the center of the anterior sacral sphere, and the ankle of the foot can be drawn vertically. It is promising, can adjust even the subtle and subtle energy aspects, and can make mental improvements.

In the present invention, the support mechanism of the lumbar support table may be such that the lumbar support table is supported by a support frame at a central portion thereof via a universal bearing, or the lumbar support table is supported. A central support plate continuously provided below the center portion, an X axis for swingably supporting the central support plate, an outer support plate for supporting the central support plate via the X axis, and an outer support plate And a Y-axis that rotates about an axis in a direction orthogonal to the X-axis on the same plane as the X-axis, and the outer support plate is supported by the support frame via the Y-axis. desirable. In any case, it is easy to adopt a structure controlled by a remotely controllable device such as a fluid pressure cylinder, and it is easy to manufacture, and at the same time, the posture changing operation of the waist placing base by the posture changing mechanism, and This is because the posture returning action by the posture returning mechanism can be easily performed by a simple operation such as simply giving a pushing-up action force by the fluid pressure cylinder. In particular, by adopting a universal bearing, the support structure is simplified, and it is easy to manufacture and can be provided at low cost.

The posture changing mechanism is arranged so that, on a concentric circle centered on the central portion of the waist placing table, a virtual line connecting the posture changing mechanisms becomes a polygon including a triangle or more. Or a plurality of the central support plate and the outer support plate are arranged in the form of a fluid pressure cylinder arranged on the support frame in a manner distributed to the left and right with respect to the respective rotation axes. It is desirable to adopt a configuration that performs the following. By setting the arrangement position on a concentric circle centering on the central part of the waist placing table or by arranging the support plate on the left and right around the rotation axis of each support plate, setting the arrangement position of the posture changing mechanism Is significantly easier, and the production is simplified. In particular, in the configuration of being arranged on the concentric circle, the posture changing mechanism, for example, increasing the number of hydraulic cylinders to be installed and further giving variety to the inclination direction of the waist mounting table portion. Since the installation work of the mechanism can be performed mechanically, it is convenient because diversity can be easily exhibited in the inclination direction of the lumbar mounting table.

It is preferable that one posture return mechanism is provided below the center of the waist placing table. By separating the operation from the attitude changing mechanism, the control of the fluid pressure cylinder can be easily performed, and the entire structure of the apparatus including the control mechanism can be simplified.

Preferably, a double-acting hydraulic cylinder is used for each of the attitude changing mechanism and the attitude returning mechanism.
This is because posture change and return operation can be performed easily and quickly as compared with a mechanical structure such as a combination of gears or a link. In the case where a pneumatic cylinder is used as the fluid pressure cylinder, since the contamination of the equipment and the installation location can be significantly reduced as compared with, for example, a hydraulic cylinder, it is particularly used in a bed for correcting the position of the center of gravity of the body. Is preferred.

The lumbar mounting table is composed of a lumbar mounting table, a spherical seat that is provided below the lumbar mounting table and controls self-alignment as a universal bearing, and a pressure receiving plate that is further provided below the lumbar mounting table. It is desirable. This is because the structure is simple and easy to manufacture.

The spontaneous drop mechanism of the support frame is provided on a double-acting fluid pressure cylinder and machine frames on both lower sides of the support frame. Desirably, it comprises a catch that can be changed. This is because the adoption of the fluid pressure cylinder can achieve the natural fall smoothly and promptly as described above. In particular, it is desirable to employ a pneumatic cylinder. This is because, as described above, the contamination of the equipment and the installation location can be remarkably reduced, so that it is particularly suitable for use in this kind of bed for correcting the position of the center of gravity of the body. It is also important to change the size of the natural drop in the vertical direction. In addition to being able to tilt in all directions as described above, it is possible to apply subtle impacts, large and small, so it is possible to make adjustments to more subtle and subtle energetic aspects, from the spiritual aspect Is also possible.

By providing a pair of right and left catches of the natural fall mechanism and synchronizing them to change the position, automatic control of the natural fall can be easily performed, and a means such as microcomputer control can be easily taken. is there. In addition, it is desirable to employ a receiving device as a unit formed with a plurality of drop dimensions set in advance and formed on the upper surface of the receiving device. This is because the automatic control of the natural fall is further simplified. Further, it is preferable that the plurality of horizontal receiving surfaces of the receiving tool are arranged in order from the next receiving surface along the driving direction of the receiving tool with the uppermost center as the center. When a large number of receiving surfaces formed on the upper surface of the receiving device are moved while forcibly driving the receiving device to obtain a desired natural fall size, and when appropriately selected, the moving size of the receiving device is substantially Halved,
This is because the device can be reduced in size and energy can be saved.

By adopting a structure in which the receiving member is provided with a plurality of receiving plates having vertical dimensions equal to the size of the large and small drops, and the receiving plates are mounted and replaced on machine frames on both lower sides of the support frame. Although it is inevitable that the work efficiency is reduced as compared with the automatic control, it is preferable because the bed for correcting the position of the center of gravity of the body can be provided at a significantly lower cost.

If the receiving member is configured to be able to change its vertical position via a drive mechanism, it is advantageous in that the receiving surface can be widened and the support frame can be stably supported.
At the same time, it is easy to adjust to automatic control.

The posture returning mechanism controls the double-acting type fluid pressure cylinders so as to equalize the pushing amount and pushes them up at once, so that they come into contact with the pressure receiving plate of the waist placing table, and The position change mechanism is also used to return the mounting table to the horizontal position, or the pair of fluid pressure cylinders provided in correspondence with the respective support plates are controlled so that the lifting amounts are equalized and are lifted at once. With this configuration, it is possible to adopt a configuration in which an attitude changing mechanism is also used so as to come into contact with each support plate and return the main part mounting table to a horizontal attitude. This is because there is no need to provide a separate posture changing mechanism, the structure of the bed for correcting the position of the center of gravity of the body is simplified, and the bed can be provided at a low cost.

Further, the bed for correcting the position of the center of gravity of the body according to the present invention can freely rotate about the vertical axis with respect to the waist placing table, and rotate about the horizontal axis. A rotatable support having a horizontal shaft that is freely held, and a rotatable support that fixedly holds a rotation about an axis of the horizontal shaft in a horizontal direction; The base is supported by the support frame so that it can be tilted in any direction with respect to the horizontal plane by being held rotatably and fixedly on the vertical support shaft provided on the support frame with the axis line facing up and down, The support frame is supported via a natural drop mechanism capable of changing the size of a drop, and a configuration can be adopted in which the elevation angle of the back mounting table can be freely changed and fixed.

By changing the direction of the rotary base support in all directions around the vertical support axis by 360 degrees and then rotating the horizontal axis appropriately, the waist mounting base can be oriented in all directions with respect to the horizontal plane, that is, The sacrum can be tilted freely within a 360-degree infinite range, and the sacrum can be tilted in any direction with high precision and accuracy, and the direction to be corrected is accurate. This is because, in particular, as shown in the embodiment, when a rotating handle is employed, it is easy for a skilled doctor to accurately show the intuition, so to speak. In addition, it is possible to provide an operation for obtaining the inclination of the waist placing table as a structure that can be easily performed by a manual operation, and to reduce the size and energy consumption of the device,
In addition, the structure is simplified, and it can be provided at a low cost.

[0024]

Embodiments of the present invention will be described with reference to the drawings. 1 to 11 show a first embodiment of a bed for correcting the position of the center of gravity of the body according to the present invention. FIG. 1 is an enlarged front view of a main part with a partial cutaway, and FIG. FIG. 7 is an overall schematic plan view thereof. The bed for correcting the position of the center of gravity of the body according to the present invention, in FIGS. 6 and 7,
From the right side to the left side in the figure, first, a back mounting base 1, a waist mounting base 2, and a leg mounting base 3 are arranged on a machine frame 4.

In the back mounting base 1, a pair of cushion bases 5 made of a material having an elongated cushioning property are fixedly arranged on a frame 6 in parallel at appropriate intervals. . The pillow 7 is provided so as to be freely changeable in position within a predetermined range from the tip of the bed toward the foot of the bed by utilizing a gap between the cushion bases 5. The back mounting base 1 has a foot fixedly attached to a horizontal shaft 9 rotatably supported at both ends on a machine frame 4 via brackets 8 on a machine frame 4. 9 is rotatably connected to an electric cylinder 10 provided below the frame 6, so that the elevation angle of the back mounting table 1 can be changed and fixed.

As shown in FIG. 12, the back mounting table 1 is configured so that the elevation angle can be freely changed and fixed. As shown in FIG. 12, the upper body is raised at an arbitrary angle by changing the elevation angle. In this way, it is possible to appropriately apply a natural fall impact to any part from the sacral lower part SK to the tail bone B. Unlike the conventional structure (FIG. 26), which only affects the first and second sacrum, the lower sacrum SK, that is, the third to fifth, and any part of the coccyge B can be accurately dropped. Can be given.

As shown in FIG. 1, FIG. 3, and FIG. 7, the waist placing table 2 includes a pair of cushion table sections 11 formed of a pair of flat trapezoidal cushioning materials. The cushion support portion 12 has a cushion support portion 12 integrally attached to a lower portion thereof. As shown in FIGS. 1 and 3, the pair of cushion support portions 12
2 provided on the support frame 13 disposed below
Each of the two parallel bars 14 is slidably attached to each other, and the two waist-folding links 15 are operated by a handle 16 to adjust the distance between the two. That is, as shown in FIG. 13, the sacrum S and the ilium T connected via the sacroiliac joint C are pressed and supported in the direction toward the sacroiliac joint C (the direction indicated by the arrow in the figure). .

As shown in FIGS. 1, 4 and 5, the waist placing table 2 is integrally attached to the lower portion of the support frame 13 so as to be able to incline in all directions with respect to the horizontal plane. Is supported by a support frame 18 via a universal bearing 17 which is an example of a support mechanism. A pressure receiving plate 19 made of a disk is integrally attached to a lower portion of the universal bearing 17.

Next, the posture changing mechanism will be described. As shown in FIG. 1, FIG. 4 and FIG.
Below the support frame 18, the waist placing table 2
, Ie, on a concentric circle centered on the longitudinal axis of the universal bearing 17, eight double-acting pneumatic cylinders 20 are arranged at equal intervals. These pneumatic cylinders 20 constitute a posture changing mechanism. Only when the pneumatic cylinder 20 moves upward, the rod 21 is pushed up by pneumatic pressure, and the upper end of the rod 21 comes into contact with the pressure receiving plate 19. Therefore, when one of the pneumatic cylinders 20 is operated to push up the rod 21, the pressure receiving plate 1 is in a horizontal posture.
9, the pressure receiving plate 19 is tilted to one side around the universal bearing 17, and the lumbar portion is mounted via the support frame 13 integrated with the universal bearing 17. The mounting table 2 is inclined to one side. In this manner, the pressure receiving plate 19, that is, the waist placing table 2 is configured to be tiltable in eight directions in the structure shown.

In the illustrated example, eight pneumatic cylinders 20 are employed, but this is merely an example. However, at least three or more pneumatic cylinders 20 are required in addition to the required minimum performance, form, size, and economy in addition to the bed for correcting the position of the center of gravity of the body according to the present invention. Although it is necessary to adopt the number, the number is selected as needed in the range of about 3 to 12 to 15 pieces. The reason why the number of 3 to 15 is selected is that if the number is less than 3, there is no difference from the conventional structure as described above, so that a remarkable effect on treatment cannot be expected. This is because it is considered to be the limit number of installations from the condition of space.

Next, the posture returning mechanism will be described. As shown in FIG. 1, FIG. 4 and FIG.
A single pneumatic cylinder 22 is disposed on the support frame 18 below the support frame 18 so as to be coaxial with the central portion of the waist placing table 2, that is, the longitudinal axis of the universal bearing 17. . The pneumatic cylinder 22 constitutes a posture returning mechanism.
The pneumatic cylinder 22 pushes up the rod 23 by pneumatic pressure only when moving upward, and its upper end is brought into contact with the center of the pressure receiving plate 19 to return the pressure receiving plate 19 in the inclined posture to the horizontal posture. It is configured to do. The distal end (upper end) of the rod 23 of the pneumatic cylinder 22 is desirably configured to have a larger diameter than the distal end of the rod 21 of the pneumatic cylinder 20 constituting the attitude changing mechanism. This is because the pressure receiving plate 19 can be more reliably returned to the horizontal posture.

Next, the natural drop mechanism will be described. As shown in FIGS. 1, 9, and 10, the natural drop mechanism basically includes the support frame 18 and the support frame 1 as shown in FIGS.
And a receiving member 24 fixedly disposed on the frame 4 at the lower left and right sides of the frame 8. The support frame 18 is connected to a cylinder rod 25A of a pneumatic cylinder 25 fixedly mounted on the machine frame 4 at a lower portion of a central portion thereof, and is supported by the operation of the pneumatic cylinder 25 so as to be vertically movable. In other words, when moving up,
It is forcibly lifted by air pressure, but when moving down,
By exhausting the air from the cylinder 25 to the atmosphere, the cylinder 25 is naturally dropped by its own weight and the weight of the patient lying on the bed.

More specifically, as shown in a partially cut-away enlarged side view of a main part of FIG. 10, the bottom of the support frame 18 is supported by the tip of a cylinder rod 25A of the pneumatic cylinder 25. With the upward movement of the rod 25A, a pin 25C having a push-up plate 25B that pushes up the support frame 18 upward is screwed. Also, this pin 25
C is a through hole 18b formed in the bottom plate 18a of the support plate 18.
The upper end is integrally provided with a slightly large-diameter plate 25D for retaining, and the pin 25C and the insertion hole 18b function as a guide.

The support frame 18 is provided with the push-up plate 25.
After being pushed upward by the upward movement of B, the downward movement of the cylinder rod 25A of the pneumatic cylinder 25 works in advance, and the support frame 18 is configured to fall along with this.

The lower four corners of the support frame 18 are vertically movably supported by a guide mechanism 4A installed on the machine frame 4. This guide mechanism 4A is shown in FIG.
As shown in FIG. 5, a guide rod 4a integrally projecting downward from the four corners of the support frame 18 and the guide rod 4a are fitted inside and a bush 4b arranged inside the guide rod 4a. And a guide cylinder 4c for smoothly moving up and down.
By A, it is configured so that a smooth vertical movement is possible without inclination.

[0036] The bushing 4b, as shown in FIG. 2, with the retainer having a guide groove 4b ₂ that allows infinite linear motion of the load ball group 4b ₁ of the plurality of rows in the circumferential direction at equal intervals, the guide rod Reference numeral 4a denotes a point contact, which is a linear movement with a minimum frictional resistance, and a highly accurate and light movement is obtained. Generally, what is called a linear bush and a slide bush (both are trade names) are employed, but it goes without saying that a conventional general bush may be employed.

The receiving member 24 is shown in FIGS.
As shown in FIG. 2, the driving source 26 held by the machine frame 4
(Electric motor as an example) is integrally connected to an endless belt-shaped belt 27 that is linked to the motor, and is configured to be repositioned by reciprocating right and left synchronously. The lower portion of the receiving member 24 is supported on a guide rail R provided on the machine frame 4 and reciprocates while being guided by the guide rail R.

The upper surface of the receiving member 24 is provided with horizontal receiving surfaces 24a to 24n, and is formed in a step-like manner from the uppermost position to the lowermost position. 24 are sequentially arranged in a distributing manner from the next receiving surface along the moving direction of 24. The level difference between the receiving surfaces 24a to 24n is as follows.
In the example shown in the figure, six steps are formed between a minimum of 0.5 mm and a maximum of 5 mm.
m, the distance between the second and sixth places is 1 mm
It is formed with a unit step. A contact piece 28 of a size sufficient to contact the receiving surfaces 24a to 24n is provided at the left and right central portions of the lower surface of the support frame 18, respectively.
(FIGS. 10 and 11) are provided.

0.5 mm, which is the minimum of the steps,
Is selected when a light impact is obtained, and is particularly useful for improving subtle and subtle energy aspects and for mental improvement. The maximum of 5 mm is selected when the greatest impact is obtained. In particular, severe cases, that is, improvement of symptoms such as extremely large displacement of the sacrum and coccyx,
Effective for healing.

It is to be noted that the step is not limited to the above-mentioned number and dimensions, but may be increased or decreased as necessary. .1 mm steps can also be employed.

Accordingly, the drive source 26 is operated to drive the belt 2
7 is rotated in the forward / reverse direction as appropriate to move the stopper 24 in the forward / reverse direction along the rail R in the plan area (FIG. 1).
In FIG. 10 and FIG. 11, the receiving surface which can obtain a dimension matching the required drop size of the support frame 18 is moved to the contact piece 28 of the support frame 18 (FIGS. 10 and 11).
Be located directly below. When the required position of the receiving surface is correctly located directly below the contact piece 28, the operation of the drive source 26 is stopped.

Next, the pneumatic pressure in the pneumatic cylinder 25 supporting the support frame 18 is exhausted at once. Then, the support frame 18 falls naturally and quickly due to its own weight and the weight of the patient on the bed, and the contact piece 28 impacts on a predetermined receiving surface having a predetermined drop size. It is accepted. In this way, the support frame 18 falls down to the required vertical dimension and is impactfully received on the receiving surface, and this impact is transmitted to the patient.

As shown in FIG. 6, the leg mounting base 3 is configured so that the vertical position can be changed and fixed via a jack-up mechanism 29. In this way, the vertical position can be changed and fixed to relax the patient as much as possible,
When the lumbar support table 2 is naturally dropped in the weakened state, the weight of the patient can be more effectively contributed to the natural fall of the lumbar support table 2 so that the patient can be turned upside down. It is configured so that the foot can be bent from the knee and supported. As a drive source of the jack-up mechanism 29, an electric cylinder (not shown) is employed. The X-shaped link pivotally connected to the intermediate portion is expanded and contracted by the operation of the electric cylinder.
The vertical position of is changed and adjusted.

In the first embodiment of the bed for correcting the position of the center of gravity of the body according to the present invention constructed as described above, the bed according to various symptoms such as the degree and direction of bending of the sacrum obtained by palpation in advance. As shown in FIG. 11, the waist placing table 2 (imaginary line portion in the figure) in a horizontal posture is firstly a posture changing mechanism in order to obtain a tilt in a direction suitable for correcting this symptom. One of the eight pneumatic cylinders 21 is selected and moved upward, whereby the waist placing table 2 is tilted around the universal bearing 17 via the pressure receiving plate 19 (solid line in the figure).

Next, as shown in FIG. 12, it is desired to correct the elevation angle of the back mounting table 1 according to the position to be corrected, that is, the order of the sacrum S or the tail bone B. The size is adjusted so that the sacrum S and the coccyx B are located right below. By adjusting the elevation angle of the back-mounting base 1, the drop impact described below can be applied to the bone portion to be accurately corrected. Further, the position of the leg mounting base 3 is also adjusted up and down as needed via the jack-up mechanism 29.

Further, the stopper 24 of the natural fall mechanism is appropriately moved so as to bring out the most preferable drop size according to the symptom, and the receiving surface for obtaining the required drop size is brought into contact with the support frame 18. It is positioned directly below the piece.

When the above-mentioned preparation work is completed, the waist placing table 2 is finally dropped naturally. As described above, the air in the pneumatic cylinder 25 supporting the support frame 18 is discharged at a stroke. . Then, the lumbar placing table 2 places the patient while keeping its inclined posture, and falls naturally and quickly together with the support frame 18 together with its own weight and the weight of the patient on the bed. . Until the contact piece 28 comes into contact with the selected receiving surface, the waist placing table 2 falls together with the support frame 18 and is received. In this way, the support frame 18 falls down to the required vertical dimension and is impactfully received on the receiving surface (FIG. 11), and this impact is transmitted to the patient. At this time, since the sacral portion or the coccyx to be corrected is at the lowest position, the drop impact is accurately transmitted to this portion, and ideal impact can be applied.

In FIG. 1, reference numeral 19A denotes the waist-mounting base 2;
A pin for preventing rotation around the universal bearing 17. The pin 19A is integrally formed with a rotation preventing plate 19B provided on the support frame 18 in a state where the operation of the cylinder rods 21 and 23 of each pneumatic cylinder constituting the posture changing mechanism 20 and the posture returning mechanism 22 is permitted. And is engaged with the pressure receiving plate 19.

With such a configuration,
The waist placing table 2 can be inclined in any direction with respect to a horizontal plane.

In the second embodiment,
The attitude changing mechanism includes the center support plate 30 and the outer support plate 32.
, That is, the axis of the X-axis 31 and the axis of the Y-axis 33 are centered, and the support frame 1
8 is formed by a hydraulic cylinder 34 disposed on the upper surface of the hydraulic cylinder 8.

Therefore, in order to incline the waist placing table 2 in the second embodiment, the following procedure is performed. That is, first, one of the hydraulic cylinders 34 arranged right and left around the X-axis 31 which is a support shaft of the central support plate 30 is operated, and the cylinder rod 35 is moved upward. While being brought into contact with the back surface of the central support plate 30, it is further pushed up. By this pushing up, the center support plate 30 is changed to the inclined posture with the cylinder rod 35 in contact with the cylinder rod 35 in the upper position and the opposite side in the lower position with the X axis as the center. In this manner, the posture of the waist placing table 2 can be changed in the left and right directions about the X axis 31 first.

Further, by operating one of the hydraulic cylinders 34 which are arranged back and forth around the Y axis 33 which is the support shaft of the outer support plate 32, the cylinder rod 35 is moved upward, While being in contact with the back surface of the outer support plate 32, it is further pushed upward. By this pushing up, the outer support plate 32 moves around the Y axis 33,
The side where the cylinder rod 35 abuts becomes higher and the opposite side becomes lower, and the cylinder rod 35 is changed to the inclined posture. In this manner, the posture of the waist placing table 2 can be further changed in the left and right directions about the Y axis 33.

As described above, in the second embodiment, first, the inclination of the center support plate 30 in the left and right directions around the X axis 31 and the left and right inclinations of the outer support plate 32 around the Y axis 33 are described.

Further, it is preferable that the tip of each cylinder rod 35 is formed in an arc surface that is convex upward. When only one of the center support plate 30 and the outer support plate 32 is inclined independently, the followability of the other support plate, which is maintained in a horizontal posture with respect to one inclined support plate, is improved. is there.

The above-mentioned posture returning mechanism can adopt the following alternative structure. That is, in the first embodiment, the pneumatic cylinder 22 is adopted for returning the posture, but this is omitted.
Only the surrounding attitude changing cylinder 20 is adopted. Then, in returning the waist placing table 2 from the inclined posture to the horizontal posture, all the cylinders 20 responsible for this posture change are moved up all at once. However, this upward movement amount is smaller than when controlling the posture change, and the pressure receiving plate 1
9 is adjusted so that all cylinder rods 21 abut against the lower surface of the pressure receiving plate 9 at a height enough to return the pressure receiving plate 19 to the horizontal position. As the cylinder used in this alternative structure, a hydraulic cylinder or an electric cylinder is employed.

Further, in the second embodiment, as partially described above, the cylinder corresponding to the central support plate 30 or the cylinder corresponding to the outer support plate 32 is at a glance.
Alternatively, if both are used, all the cylinders are moved up at once. However, the amount of upward movement is smaller than when controlling the posture change, and the cylinder rod 35 evenly contacts the lower surfaces of the support plates 30 and 32 to return the support plates 30 and 32 to the horizontal posture. It is adjusted to be a sufficient height position. In this case, a hydraulic cylinder or an electric cylinder is used as the cylinder.
