Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pair of main rollers that perform a pressing operation in parallel with the back vertebrae, and an auxiliary roller separate from the main rollers, and the auxiliary rollers move together with the main rollers while independently moving. This invention relates to a rolling pine surge machine that performs a pressing operation.

In order to perform pine surgery on the neck of a human body in this type of conventional pine surge machine, an auxiliary roller is separately provided at the neck position of the bed, and a drive mechanism separate from the main roller is used to press or perform pine surgery on the neck. I made it. This is because when a human body lies supine on a bed, the human neck is curved upwards, so the main rollers formed to press both sides of the back vertebrae are large and spaced widely, making it difficult to apply appropriate pressure. This was because it was unable to function. Therefore, as mentioned above, there are some devices that separately install an auxiliary roller to perform the pressing operation, but the conventional auxiliary roller not only requires a complicated drive mechanism for pressing, but also causes damage to other parts. Since it cannot be used for other purposes, if necessary, it is necessary to provide a large number of rollers facing each body part.

In view of the above-mentioned current situation, it is an object of the present invention to provide a pine surge machine that has a simple structure and is efficient. A pair of support arms are swingably supported on the support shafts of a pair of main rollers, and a pair of auxiliary rollers are mounted on the support arms. It is characterized by being able to move,
The undulating state of the auxiliary rail is changed as necessary, and the auxiliary roller is configured to be raised higher than the main roller at the required location, and the desired pressing action is applied to the main roller by the small and narrow auxiliary roller. This makes it possible to do this instead. The gist of the present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a plan view showing the main parts of the pine surge machine of the present invention, with the half including the drive motor removed. Figure 2 is a side view of the same essential parts, Figure 3 is Figure 1A
- It is a sectional view of the A line part.

In the drawings, reference numeral 1 denotes a pair of main rollers supported by a support shaft 2, which moves as a pair of rollers 3 mounted on both ends of the support shaft 2 move on the main rail 4. 5 is a drive motor (not shown)
The support shaft 2 is held elastically in the guide groove 7 of the movable frame 6 screwed into the drive screw shaft by the groove bottom 7a via the spring 8, and is rotated by the undulations of the main rail 4. Therefore, the spring 8 is made to expand and contract. These are similar to those used in known rollers of this type. Reference numeral 10 denotes a pair of auxiliary rollers according to the present invention, whose base end 11b is connected to the support shaft 2.
It is supported via a shaft 12 on a support arm 11 which is mounted on a shaft, and its vertical movement is restricted along an auxiliary rail 15 which is held between a roller 13 and a rotation guide 14 provided at the bent end 11a. Therefore, the auxiliary roller 1
0 is simultaneously moved horizontally by the horizontal movement of the main roller 1, and is also moved vertically in response to the ups and downs of the auxiliary rail 15. Furthermore, as is clear from the drawings, the auxiliary roller 10 is smaller and thinner than the main roller 1, and is assembled with narrower spacing between them. Therefore, it is easy to insert into a curved part of the human neck, and an effective pressing operation can be performed.

Next, the main rail 4 and the auxiliary rail 15 are formed from a single plate 20, as shown in FIG. In the embodiment, the auxiliary rail 1
5, as shown in the second figure, is provided with an inclined part 15a so that the auxiliary roller 10 is raised higher than the main roller 1 at the neck position, but if necessary, the auxiliary roller 10 is provided with a sharp part at a vital point on the back of the human body. It goes without saying that the undulations of the auxiliary rail 15 can be taken into consideration so that the pressing force can be applied appropriately.

In the pine surge machine of the present invention having the above configuration, the normal pressing pine surge is performed by the main roller 1.
However, in places such as the human neck where the main roller cannot apply appropriate pressure, the auxiliary roller 10 is moved along the inclined portion 15a.
The main roller 1 can automatically push up the body and apply an appropriate pine surge to the human neck using its narrow and thin roller periphery. Considering the undulations of both rails as desired, such as leaving a slight pressing force,
Various aspects can be varied. Therefore, if the combination of the undulations of the auxiliary rail 15 and the main rail 4 is taken into account as necessary, it is possible to perform extremely excellent pine surgery not only on the neck but also on other parts of the human body, thereby improving the treatment of the human body. Not only can it exhibit excellent characteristics that can further enhance the effect, but since only two sets of rollers are used, the structure is simple and it can be provided at a low price.
