Description

[Detailed Description of the Invention] This invention relates to a roller treatment machine equipped with a shoulder kneading mechanism.

Conventionally known roller therapy machines have not been equipped with a mechanism for directly kneading the patient's shoulders. This seems to be because it was thought to be quite difficult to massage the patient's shoulders while the patient was lying on a base.

This device allows patients to rub their shoulders even when they are completely lying down.

This will be explained below with reference to the illustrated embodiment.

The treatment machine shown in Fig. 1 has a movable frame 2 on a base 1.
This base 1 is equipped with various rollers 3 that can be moved up and down.

A desired roller 3 is raised above the upper surface of the base 1 to press the patient lying on the movable frame 3 using its own weight.

The moving frame 2 reciprocates in conjunction with a motor (not shown), and each frame member 4
A canvas or the like is stretched between 7 and 7.

Among the above-mentioned frame members, the front frame member 4 has a raised casing 8 that houses the shoulder massaging drive mechanism, and casings 9 and 10 that house the traction force generation mechanism on the rear sides of both frames 6 and 7. is raised.

The traction force generating mechanism housed in the casings 9 and 10 has the following configuration.

That is, as is clear from FIGS. 2 to 6, installation plates 11 and 12 are fixed to the rear sides of the frame members 6 and 7 on both sides.

A screw shaft 15 is rotatably installed between the support pieces 13 and 14 on the installation plate 11, and a pulley holding body 16 is engaged with the screw shaft 15. A guide rod 17 is installed below the screw shaft 15, and this guide rod 17 passes through the pulley holding body 16. Therefore, when the screw shaft 15 rotates, the pulley holding member 16 is prevented from rotating by the guide rod 17, so that it moves in the axial direction of the screw shaft 15. A driving source for rotating this screw shaft 15 is a motor 18. That is, a chain 21 is wound between a chain wheel 19 directly connected to the motor shaft and a chain wheel 20 provided on the screw shaft 15, so that the rotational force of the motor 18 is transmitted to the screw shaft 15.

Pulleys 22 and 23 are provided on both sides of the pulley holding body 16 which is movable along the screw shaft 15 as described above.

On the other hand, a supporting piece 2 is attached to the other installation plate 12.
2 screw shafts between 4 and 25 26, 2
7 is rotatably installed, and pulley holding portion bodies 28 and 29 are engaged with these screw shafts 26 and 27, respectively.

As is clear from FIG. 5, guide rods 30 and 31 pass through the holding bodies 28 and 29, and when the screw shafts 26 and 27 rotate, the pulley holding bodies 28 and 29 move. , the same as in the case of the pulley holding body 16.

And the three screw shafts 1 mentioned above.
5, 26, and 27 rotate integrally using the motor 18 as a driving source, and the linkage mechanism thereof is as shown in FIG.

That is, the endless chain 33 is wound around the chain wheel 32 on the outside of the support piece 13 which is the rear end of the screw shaft 15 connected to the motor 18 as described above, and the chain wheels of the other screw shafts 26 and 27 are 34, 35
The endless chain 33 is wound around and connected to the chain. Note that numerals 36 to 40 in the figure are guide wheels.

However, when the motor 18 rotates, the screw shaft 15 rotates and the chain wheel 32 also rotates. chain wheel 32
When the endless chain 33 rotates, the endless chain 33 runs, simultaneously turning the chain wheels 34 and 35, and rotating the screw shafts 26 and 27.

Although pulleys 41, 42 and 43, 44 are provided on both sides of the pulley holding bodies 28 and 29, the pulley 43 is only shown in FIG. 6, which schematically shows the mechanism. This FIG. 6 schematically shows the entire assembly on the side of the installation plate 12, with the pulley holding parts 28, 29, etc., which are stacked one on top of the other, separated into left and right sides.

A mechanism related to the pulley holding body 16 on the installation plate 11 side and a mechanism related to the pulley holding body 28 on the installation plate 12 side are for pulling the lumbar vertebrae.

That is, wires 45, 46 are wound around the pulleys of both pulley holding parts 16, 28, and one ends of these wires 45, 46 are fixed to ends of rods 49, 50 of traction force generating mechanisms 47, 48. There is.

The rods 49, 50 are connected to support pieces 51, 52, 53, 54 that stand up in front of the support pieces 14, 25.
Stoppers 55 and 56 are provided on the rods 49 and 50 so as to be movable in the axial direction between them.
Coil springs 59 and 60 are interposed between the bearings 57 and 58.

However, when the wires 45, 46 are pulled in the direction of the arrow in FIG. 6, the rods 49, 50 are drawn in the direction of the arrow, causing the coil springs 59, 60 to deflect. When the coil springs 59, 60 are bent, the reaction force acts on the wires 45, 46, and this reaction force of the coil springs 59, 60 acts as a traction force.

And one rod 49 has a traction force sensor 6
This traction force sensor 61 electrically detects the amount of movement of the rod 49 and controls the motor 18.

The wires 45, 46, whose one ends are fixed to the rods 49, 50, are wound around one of the pulleys 22, 41 of the pulley holding parts 16, 28 and made a U-turn. It is wrapped around pulleys 65 and 66.

Wire 4 wrapped around fulcrum pulleys 65 and 66
5 and 46 are now wound around the other pulleys 23 and 42, and further led out from the guide arch member 67 onto the movable frame 2. The wires 45 and 46 led out onto the movable frame 2 are wound around movable pulleys 70 and 71 provided with hooks 68 and 69 specifically shown in FIG. 7, and returned to the guide arch member 67 again.
Further, the ends thereof are wound around drums 72 and 73.

Electromagnetic clutches 63, 64 are integrally connected to the drums 72, 73. These drums 72 and 73 are given a force in the direction of winding the wire by a spring force, but when the electromagnetic clutches 63 and 64 are actuated, they are fixed at the winding position.

With the hooks 68, 69 fixed to the waist of the patient lying on the moving frame, the electromagnetic clutches 63, 64 are operated, the motor 18 is rotated, and the pulley holding bodies 16, 28 are moved in the direction of the arrow. When the rods 49 and 50 are moved, reaction forces of the coil springs 59 and 60 are generated. As mentioned above, this reaction force becomes a traction force.

The mechanism related to the above-mentioned pulley holding body 29 is as follows:
It provides traction to the cervical vertebrae.

This mechanism is exactly the same as the mechanism on the installation plate 11 side, and 74 is a wire, 75 is a traction force generation mechanism, 76 is a traction force sensor, 77 is a fulcrum pulley, 78 is a hook, 79 is a movable pulley, and 80 is a drum. , 81 is an electromagnetic clutch.

However, in this mechanism, in order to lead out the hook 78 from the front side of the movable frame 2, the hook 78 is first passed under the frame member 6, and the guide roller 82,
I am using 83.

Next, the shoulder massaging mechanism will be explained based on FIGS. 8 and 9. This mechanism uses a motor 84 installed on the front frame member 4 as a driving source. This motor 84
When the transmission chain wheel 87 rotates, the transmission chain wheel 87 rotates through the bevel gears 85 and 86, and the chain wheel 89, which is connected to the transmission chain wheel 87 through the chain 88, rotates, and the winding drum 90 rotates.

One end of a wire 91 is wound around the winding drum 90. This wire 91 is wound around one movable pulley 93 provided on a floating body 92 to make a U-turn, and the other end is wrapped around a hooking piece 94. It is fixed at

Further, another wire 96 is wound around the other movable pulley 95 of the floating body 92, and both ends of this wire 96 are connected to a drive lever 97 shown in FIG.
is connected to.

This drive lever 97 is attached to the lower side of each of the frame members 6 and 7 on both sides,
Only one drive lever is shown in the drawing. That is, this drive lever 97 is fixed to a rotating shaft 98 rotatably supported by the frame members 6 and 7.

Shoulder massage levers 99 and 100 are fixed to the upper end of the rotating shaft 98.

When the motor 84 is driven, the floating body 92
is drawn toward the motor 84, and the wire 96 is pulled accordingly. When the wire 96 is pulled, the drive lever 97 and the shoulder massage lever 9
9 and 100 rotate to press the shoulders of the patient lying on the moving frame 2.

As is clear from the above description, according to the treatment machine of this invention, a patient lying on the movable frame can perform shoulder massage while receiving pressure treatment by the rollers. Therefore, the combination of pressure treatment and shoulder massaging can greatly improve the therapeutic effect.
