Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pine surge machine that performs pine surge using rollers.

In the conventional pine surge machine, as shown in Fig. 1, the cover sheet 6' covers the kneading roller 2' without giving it any slack, so using the inclined roller 2' will shorten the life of the roller 2'. had become shorter due to friction. This tendency is particularly strong when the roller 2 is made of gum. Therefore, a bed-type pine surgery machine that attempts to create slack in the cover sheet 6' has a problem in that the body sinks.

The present invention has been made in view of the above points, and its object is to provide a pine surgery machine that can reduce the friction between the roller and the cover sheet and prevent the body from sinking.

The gist of the present invention is to provide a rotating ring 47 eccentrically inclined in the same direction as the rollers 2, 2 between a pair of rollers 2, 2 which are eccentrically inclined on the rotationally driven shaft 1;
The roller 2 is covered with a double cover sheet 6, the outer sheet 6a is stretched, and the inner sheet 6b is loosened along the roller 2, and the slack portion of the inner sheet is formed of a material with a small coefficient of friction. This relates to a pine surge machine. Hereinafter, the present invention will be explained in detail based on illustrated embodiments. In the illustrated example, a mattress member is arranged in a bed on which the whole body can be laid down.
This bed has legs 42 with Rails 7 with openings facing each other are provided on the inner surface of the
Furthermore, a rack 8 is fixed to each rail 7 along its longitudinal direction, and a pillow 45 is provided on the upper surface of one longitudinal end, and a handle bar 46 is provided from this one end. The pillow 45 is detachable or can be pivoted at one end to the bed so that it can be removed from the top surface of the bed and hung below the handle bar 46, and the handle bar 46 can be placed horizontally on the bed. It is designed so that it can be grasped in a sagging position, and is designed to prevent the pine surge member of the body from twisting as it moves when performing the pine surge, so that the pine surge effect can be effectively obtained. This is what we do.

Now, between the pair of rails 7, 7, there are three types of pine surge rollers 2 as pine surge members.
A mechanism section equipped with 4 and 5 is installed. This mechanism section has a motor M that can freely rotate in the forward and backward directions, and is self-propelled along the rail 7, and is composed of a main block equipped with rollers 2 and 5, and a sub-block equipped with a roller 4. A motor block 9 is arranged at one end of the main shaft 1 with the rollers 2, 2 mounted in the center, and a gear box 10 is arranged at the other end.
Side rollers 5, 5 are arranged on the upper surfaces of the main block and the gearbox 10, respectively, so as to freely rotate with shafts 59, 59 parallel to the main shaft 1, and are arranged at intervals in the longitudinal direction of the main block and the bed. The sub-block is connected to the main block by a pair of connecting plates 51, and a total of four sub-rollers 4 are attached to a shaft 50 parallel to the main shaft 1.

Guide rollers 1 are provided on cylindrical bodies 16, 16 which are freely rotatably attached to both ends of the main shaft 1, respectively.
7, 17, and guide rollers 17, 17 attached to both ends of a shaft 58 parallel to the main shaft 1 supported by the motor block 9 and gearbox 10 are arranged so as to be able to run freely within the rails 7, 7, so that the main block is A sub-block is constructed between the rails 7, 7 by the guide rollers 17, 17 attached to both ends of the shaft 50 being arranged so as to be able to run freely on the rails 7, 7. As shown in FIG. 4, the main shaft 1 is hollow, and a drive shaft 3 to which the cylinders 16, 16 are fixed at both ends is inserted into the main shaft 1, and a pinion 15 provided in each cylinder 16 is inserted into the main shaft 1. is engaged with the rack 8 attached to the rail 7, so that when the drive shaft 3 is driven to rotate, the main block and the sub-block connected thereto, that is, the entire mechanism runs along the rails 7, 7. do.

The motor M is connected to the main shaft 1 and the drive shaft 3 by a gear group and a planetary part in a gearbox 10.

As is clear from FIG. 4, the roller 2 attached to the main shaft 1 includes an eccentric inclined shaft portion 21 fixed to the main shaft 1, and a rubber outer ring arranged freely around the outer circumference of the eccentric inclined portion 21. 22, the outer ring 2
A steel ball 24 and a retainer 23 are disposed between the shaft 2 and the eccentric inclined shaft portion 21. Spindle 1 at a predetermined interval
This pair of rollers 2, 2 attached to the main shaft 1
However, both rollers 2, 2 rotate together.
are both eccentric by the same amount in the same direction and are inclined line-symmetrically. Therefore, when the main shaft 1 rotates, the amount of protrusion of the roller 2 toward the cover sheet 6 side changes, and at the same time, both rollers 2, 2 The distance between each contact portion with the cover sheet 6 is changed. The cover sheet 6 is a double sheet consisting of an outer sheet 6a and an inner sheet 6b. As shown in FIG. 4, the outer sheet 6a is stretched, and the inner sheet 6b is made wider than the outer sheet 6a and is loosened along the roller 2 on both sides of the roller 2.
Both sheets 6a and 6b are stacked and fixed to a frame 40. The inner sheet 6b is made of a material with a low coefficient of friction, such as nylon, polyester, or polypropylene, and the outer sheet 6a is made of Teflon or the like, which is comfortable to the skin and has high strength. However, even if the roller 2 operates as shown in FIGS. 5a and 5b, it becomes one with the roller 2,
The inner sheet 6b moves, and the roller 2 and the inner sheet 6
When b and b rub against each other, it disappears.

FIG. 6 shows another example of the cover sheet 6,
The inner sheet 6b is arranged only in the operating range of the roller 2. Both sides of the inner sheet 6b are welded to the outer sheet 6a.

However, in the case of a lever, the person lies down with the whole body on the cover sheet 6 and places the head on the pillow 45 at one end.
If the drive shaft 3 is rotated without rotating the main shaft 1, the mechanical part will be moved along the rail 7 below the cover sheet 6, that is, by the engagement between the pinion 15 of the drive shaft 3 and the rack 8. self-propelled along the longitudinal direction of the During this running, the outer ring 22 of the roller 2 located on the head side presses both sides of the spine on the back of the human body along the spine via the cover sheet 6, and also presses the back of the human body along the spine. The sub-rollers 4 located on the sides, particularly the rollers 4 at both ends, keep a constant distance from the roller 2 and press the calves of the feet. This is how we perform sasuri pine surge. Further, since the roller 2 is eccentric and inclined with respect to the main shaft 1, as it rotates, the amount of protrusion towards the cover sheet 6 side is large and the distance between the upper ends of both rollers 2 is small, and the cover sheet 6 side A state in which the amount of protrusion is small and the distance between the upper ends of both rollers 2 is large alternately occurs, and this causes the twisting and pine surge. Furthermore, as shown in FIG. 3, between the pair of rollers 2, 2, there is provided a rotating ring 47 which is eccentrically placed like the roller 2, and this rotating ring 47 rotates the roller 2 to perform twisting and pine surge. When the part with a wide gap between both rollers 2, 2 is located on the cover sheet 6 side, the body may be too close to both rollers 2, 2.
The body is pushed out from between the rollers 2, 2, and the body is pushed out from between the rollers 2, 2 when the narrow part of the rollers 2, 2 comes to the cover sheet 6 side. This was provided to prevent people from getting their necks caught between the two.

In the present invention, a rotating ring is provided between a pair of rollers that are eccentrically inclined in the same direction as these rollers, so that the rollers can be rotated by the rotating ring. When performing twisting and pushing pine surge, when the part with a wide gap between both rollers is located on the cover sheet side, the body can fully fit between both rollers and the kneading effect of twisting and pushing is good. When the rollers come to a narrow part, it is possible to prevent your body from being pushed out from between the rollers and getting your neck caught between the two rollers. In this case, there is an advantage that the kneading effect can be enhanced by using a rotating ring that is eccentric in the same direction as the roller. Moreover, since the outer sheet is stretched and the inner sheet is loosened along the rollers, and the slack portion of the inner sheet is made of a material with a small coefficient of friction, the loosened inner sheet and the rollers move as one. Therefore, the roller does not rub against the inner sheet and the roller wears out, and the inner sheet and outer sheet rub, but since the inner sheet is made of a material with a small coefficient of friction, the inner and outer sheets do not rub against each other and the sheet wears out. The advantage is that there is nothing to do.
