Description

[Detailed description of the invention] The present invention is a pine surge device that performs a rubbing action on the back etc. by the reciprocating motion of the rubbing roller, and is equipped with a massage roller that massages the neck etc. using the movement of the rubbing roller. related to things.

A pine surge device that performs a rubbing operation on the back by obtaining reciprocating motion of a rubbing roller by, for example, propulsion of a rotating screw shaft is well known, and is disclosed in Utility Model Application No. 53-7645 filed by the applicant of the present application.
The No. 1 pine surge device is one example.

Such a reroller moves the back in the vertical direction, that is, moves along the pillar on both sides, and cannot move in the direction perpendicular to this.

In addition, when it comes to the neck, etc., it lifts up when lying on your back, making it difficult for the reroller to work on it.

The present invention is intended to eliminate the above-mentioned drawbacks, and the details of the structure and operation are as follows.

FIG. 1 shows the kneading mechanism of the present invention viewed from the front.

10 is a reroller to be inserted, 12 is a support for the reroller to be inserted, 14 is a guide rail, 16 is a rotating screw shaft that propels the supporter 12, 18 is a roller that allows the supporter 12 to slide smoothly on the guide rail 14, Reference numeral 20 denotes a lip that projects from the lower part of the support body 12 in order to eliminate the torque generated by the rotating screw shaft 16, and is slidably inserted between the guide rails 14 and 14.

That is, the reroller 10 reciprocates along the guide rail 14 depending on the direction of rotation of the rotating screw shaft 16.

Reference numeral 22 denotes a frame of the kneading mechanism, and leg portions 24 extending downward from both left and right sides are fixed to the guide rail 14.

In this embodiment, the frame 22 includes the guide rail 1
4, that is, near the turning point of the rubbing roller 10.

A swing arm 26 is pivotally connected to the frame 22 by a pivot 28.

The direction of rotation of this swing arm 26 is
4 (the moving direction of the rubbing roller).

30 is a torsion coil spring wound around the pivot 28, one end of which is inserted into a hole drilled in the frame 22, and the other end is locked to the swing arm 26 so that the swing arm 26 falls outward. It is energizing.

The kneading roller 32 is located at the tip (upper end) of the swing arm 26
It is rotatably mounted on the

An intermediate position between the pivot 28 and the kneading roller 32 is a bent portion of the swing arm 26, and the swing arm 26 is formed by connecting plates 26' and 26'' with a connecting shaft 34 so as to be flexible.

However, a stopper 36 that abuts the plate 26'' is provided at the lower inner side so that the plate 26' is only bent outward.

Further, a torsion coil spring 38 is wound around the connecting shaft 34 to press the plate 26' inward.

That is, if a predetermined amount of pressure is applied to the massaging roller 32, the plate 26' will fall outward and the swing arm 26 will fall.
The spring 38 maintains the straightness of the swing arm 26 until it is bent and stopped by the stopper 36 if the pressure is below a predetermined value.

In this embodiment, the connecting shaft 34 is fixed to the plate 26'', one end of the spring is locked in a slot provided in the connecting shaft 34, and the other end is locked to the plate 26'. .

However, it is also possible to make the swing arm 26 unbendable.

The lower end of the swing arm 26 is bent into an L-shape, and a roller 42 that slides on a pivot shaft 40 parallel to the axial direction of the swing arm 26 is attached.

The configuration of such a kneading mechanism is symmetrical,
Axis C is an additional axis of symmetry, but it would also be possible to configure it only on one side.

Next, FIG. 2 is a side view showing a part of the pine surge device including the kneading mechanism.

A movable piece 44 is fixed to the support 12 and moves into and out of contact with the sliding roller 42 as the support 12 reciprocates.

As shown in Figure 3, the width is narrow at the front and gradually widens at the rear.

46 is a contact wall with the underroller 42.

The operation of this first embodiment will be explained.

When the rotary screw shaft 16 is rotated by the motor and the support body 12 works, the rubbing reroller 10 approaches the kneading mechanism while performing a rubbing motion on the back.

When approaching a certain point, the vicinity of the tip of the moving piece 44 comes into contact with the sliding roller fat.

As the support body 12 further advances, the moving pieces strongly push the sliding rollers 42 outward without resisting the spring 30, so the swing arm 26 rotates around the pivot 28, and the massaging rollers 32 move inward.

This pushes, for example, the nape of the neck inward from both sides.

At this time, if too much force is applied to the neck muscles (when the reaction from the body is excessive), swing arm 2
6 is bent outward at the connection shaft 34, preventing the kneading rollers 32 from moving any further.

When the movable piece 44 pushes the bottom roller 42 to the outermost side, the support body 12 switches to a limit switch (not shown).
The rotating screw shaft 16 starts rotating in reverse.

Therefore, the support 12 begins to retreat (move in the opposite direction),
The width of the contact portion between the moving pieces with the full roller 42 changes from the maximum to the minimum.

Therefore, when the swing arm 26 was bent, it returns to its original position, and the massaging rollers 32 are slowly moved outward by the springs 30.

In this way, between the approach and the retreat of the reroller 10, the kneading rollers 32 move inward and return to the outside again due to the action of the moving piece 44 and the spring 30, and the direction is the same as the reciprocation of the reroller 10. At right angles to the direction, the neck or the like is inserted with or without the upper sheet of the pine surgery device.

As is already clear from the above description, the kneading action of the kneading rollers 32 is determined by the shape of the movable piece 44.

For example, when the movable piece 144 is formed into a gourd shape as shown in FIG. conduct.

If the front side of the dashed line is removed, there will be two reciprocating movements.

By employing this movable piece 144, the kneading mechanism can be provided at an intermediate position instead of being provided at the end of the guide rail 14 (that is, near the turning point of the reroller 10).

When provided in the middle in this way, the moving piece passes between the bevel rollers 42 and 42 and then enters between the bevel rollers on the opposite side again, so the contact walls of the movable piece must be symmetrical in front and back. Dew.

The one in Figure 4 is an example. FIG. 5 shows another example of the moving piece 244, in which the width of the moving piece 244 repeatedly widens and narrows and becomes wider as a whole as it goes toward the rear.

The contact wall 246 therefore describes a serpentine line.

It will be understood that this moving piece 244 can be employed only in an embodiment in which the moving piece 244 is provided near the turning point of the reroller 10 that the kneading mechanism points to.

In this case, the kneading rollers 32 move inward while swinging from side to side, and return to the outside while swinging as the moving piece 244 moves away, thereby providing an ideal kneading action.

It is clear that if this movable piece 244 is made into a front-back symmetrical shape so that the width narrows at the rear while repeating widening and narrowing, the kneading mechanism can be provided in the middle of the guide rail.

Incidentally, in the above-mentioned embodiment, the flat roller 42 is provided at the portion that contacts the movable piece 44, 144, or 244, but the roller 42 may not be provided and the roller 42 may directly contact the swing arm 26.

Furthermore, it would also be possible to have the contact portion of the moving piece not at the lower end of the swing arm 26 but at an intermediate point between the pivot shaft 28 and the kneading roller 32.

In this case, since the kneading rollers 32 open outward when the wide portion of the moving piece acts, the spring 30 of the pivot 28 must push the swing arm 26 inward.

As described above, in the present invention, the kneading roller acts in a direction perpendicular to the direction of action of the reroller, resulting in a variety of operations, and the synergistic pine surge effect of both rollers can be obtained on the neck, back, legs, etc. It will be done.

The operation of this kneading roller utilizes the reciprocating motion of the reroller without using an independent drive mechanism, so it has the advantage of a simple structure and low power consumption.
