Abstract

PURPOSE:To decrease a friction resistance between a bed face and a human body and to obtain a sufficient drawing gravity force under a small inclined angle by constituting dividedly a bed of a leg part, a bed of a waist part and a bed of a head part and vibrating only the bed of the waist part in the direction perpendicular to the longer direction of the bed. CONSTITUTION:A bed part is constituted of a bed of a leg part 9, a bed of a waist part 10 and a bed of a head part 11. A waist part vibration mechanism is constituted in such a way that rotation of a motor 12 is transmitted to a speed reducer 14 by means of a V belt 13 and a driving plate 15 fixed on an output shaft 14a thereof is rotated in the arrow mark direction B. As one end of a rod end 16 is fixed on an eccentric position of the driving plate 15 and another end is connected with a vibration plate 18, a rotational movement of the driving plate 15 is transformed to a reciprocating motion (in the arrow mark C direction) and a vibrational amplitude movement of the bed of a waist 10 is performed. In case of drawing of the lumber vertebra, after a body is fixed by making a side part fixing band 20 pass through from both sides and both ends are fixed on supporting arms 21, the surface of the bed is gradually inclined through a bed standing mechanism to obtain a pull-up gravity force. In addition, by performing the vibrational amplitude movement of the bed of a waist by means of a waist part vibrating mechanism friction is reduced and a stable drawing gravity force is obtd.

The above-mentioned traction is performed by performing a g-drop. Furthermore, in the case of cervical traction, the cervical ◆ff brace is fixed to the jaw (7
, the bed surface is gradually tilted to reduce the suspension gravity t7 to obtain a traction effect.

[5 Problems to be Solved by the Invention] However, since the bed of the traction platform is composed of a single plate, it is difficult to obtain traction gravity by gradually tilting the bed surface. , I between the bed surface and the human body
There was a drawback that the friction resistance generated in the N was large, and if the angle of inclination was increased, it was not possible to generate a sufficient traction force.

SUMMARY OF THE INVENTION The object of the present invention was to provide a slope traction device in which the frictional resistance between the bed surface and the human body is reduced when obtaining traction gravity, and a sufficient traction gravity of 1q can be obtained with a small inclination angle. is to provide.

The bed is divided into a lumbar bed and a head bed, and is provided with a lumbar rocking mechanism that swings only the lumbar bed independently in a direction orthogonal to the longitudinal direction of the bed.

[Function] As described above, in the present invention, the lower back oscillation [11
By swinging one part of the bed from side to side, the friction generated between the bed surface and the human body can be reduced, so it is possible to obtain stable traction gravity with a small inclination angle.

[Example] Hereinafter, details of the present invention will be explained using examples shown in the drawings.

As shown in FIGS. 1 and 2, a first bracket 2 having an inverted trapezoidal shape in side view is fixed to the bottom side of the central part in the longitudinal direction of the bed frame 1, and a main body frame 3 A second bracket 4 having a trapezoidal shape in side view is fixed opposite to the first bracket 22, and these first and second brackets 2, 4 are connected to each other via a shaft 5. The second bracket 4 is rotatably supported.
The IF unit rotor is pivotally supported by the motor vehicle through a support bracket 7, and the tip of the 0-motion rod 6a of the ACADEMY 6 is provided at the lower part of the first bracket 2. It is rotatably supported by the connecting member 8. Therefore, the head side of the bed frame 1 moves up and down with respect to the horizontal state via the first bracket 2 due to the forward and backward movement of the actuator 6'1'.',1'' as shown by I! ? It is structured so that In addition to the bed upright mechanism configured as described above, the main body frame 3 houses an electric RI circuit (not shown), and an operation panel 3o is disposed on the front.

On the other hand, the bed part is # as shown in Figures 1 and 5.
It is composed of a lower back bed 9, a lower back bed 1o, and a head N+ bed 11, and is made strong enough to withstand the bodies #θ of two people in consideration of the case where it is used as a body surge table. The WI section bed 1o is provided with a swinging mechanism that swings the M section in a direction orthogonal to the longitudinal direction of the bed, that is, from side to side, with a human body lying on its back. That is, the J
l/' The JS swing mechanism is as shown in Figures M3 to 6.
A motor 12 attached to the mounting plate 31, a reducer 14 to which rotation of the motor 12 is transmitted via the V-belt 13, and a reducer 14 attached to the output 14a of the reducer 14.
As is clear from FIG. From the rocking plate 18 attached via @17
I6 has been completed.

Therefore, with such a configuration, the waist 1 rotary mechanism controls the rotation of the motor 12 by using the V-belt 13 to control the speed reducer 1.

・One end is attached to the GJ, and the other end is attached to the swing plate 18 by i!
[! As shown in FIG. 6, the rotational movement of the driving plate 15 is converted into a reciprocating movement 1FIJ (in the direction of arrow C), thereby causing an oscillating movement of the lumbar bed 10.

The lumbar bed 10 is provided with a positioning stop circuit so that the bed always remains stationary at the center of the bed when time is up. One magnet shown in Fig. 4 [This is a sentry for the outside.

Although not shown in the drawings, a thermal heater is built into the lumbar bed 10 to warm the lumbar region. The thermal heater employs a planar photothermal body with self-temperature control, and the surface temperature is set at 70°C.

This heating element is made of a polyester IB board printed with a resistive film made of a special plus book and a conductive material. When a voltage is applied between the two terminals, the temperature of the resistive film rises and at the same time the resistance between the two poles increases. Since the current increases and the current decreases, the temperature rise is controlled, making the heater highly safe.

Next, the operation of the traction device configured as described above will be explained. In the case of lumbar traction, as shown in FIG. 7, armpit fixing bands 20 are passed through both sides to fix the body, and both ends are fixed to support arms 21. After this, the bed surface is gradually tilted using the bed raising mechanism. !
! Heavy) 1 is set to 19. At this time, since gravity is proportional to the body weight and the inclination angle and inversely proportional to the frictional resistance between the bed surface and the human body 22, Wa8I! By vibrating the lumbar bed 10 using the vibration mechanism, friction is reduced.
This allows a stable traction force.

Further, by applying the principle of handstand, the ankle fixing band 23 is fixed to the hook fitting 24 on the side of the leg bed 9, and the bed surface is set in a predetermined direction at 31 as shown in FIG. The angle is rotated U, and the state is reversely suspended. This makes it possible to perform traction on both lower limbs and the lower back. In addition,
At this time, the armpit fixing band 20 is removed.

In the case of cervical traction, as shown in FIG. 9, the traction effect can be obtained by fixing the cervical brace 25 to the jaw and performing the same operations as described above. In addition, this lumbar region swinging mechanism can reduce the pine surge effect by keeping the bed in a horizontal state and only swinging the lumbar region, and can also be used independently in addition to the traction device.

[Effects of the Invention] As described in detail above, according to the slope traction device according to the present invention, the bed is divided into a leg bed, a lumbar bed, and a head bed, and only the lumbar bed is independently moved in the longitudinal direction of the bed. Since the structure is equipped with a lumbar rocking mechanism that swings from side to side in a direction perpendicular to By swinging only the lumbar bed to the left and right using the lumbar rocking mechanism, it is possible to reduce the traction force by 1q, which is stable compared to the conventional method.
It creates an overwhelming effect of being able to do things.
