Description

DETAILED DESCRIPTION OF THE INVENTION The present invention includes a pair of rotationally driven, eccentrically inclined kneading wheels arranged on the back surface of a sheet-like cover, and the kneading wheels are movable along the back surface of the cover. This relates to a pine surge machine that transmits the movement of a massage ring to the human body.

In this type of pine surge machine, by rotationally driving an eccentrically inclined kneading wheel, the pine surge can be performed by pushing and pushing through the cover, and by moving the kneading wheel, the pine surge position can be changed, and the pine surge can be performed through the cover by moving the kneading wheel. This makes it possible to straighten the back, but if this pine surge machine is one that can bear a large amount of human body weight, for example, if it is configured in a bed shape as shown in Figure 1, the following problems may occur: .

In other words, if the cover 6 is left slack as shown by the broken line in FIGS. 1 and 2, the body will sink and the massaging ring 2 will
When moving, the amount of correction A by the massaging ring 2 is small,
There is a risk of damaging the pillar.

On the other hand, if tension is applied to the cover 6, as shown in FIG.
The movement at the contact portion with the cover 6 only causes the material to slip between the material and the cover 6, and does not provide a sufficient kneading sensation to the human body.

The present invention has been made in view of these points, and its purpose is to provide a cover with slack so that the massaging wheel is rotated and a sufficient amount of massage is applied to the human body. To provide a pine surge machine which prevents the human body from sinking due to the sagging of the cover and impairs the safety of the human body when moving the kneading wheel.

The present invention will be described below.The present invention provides slack in the cover, and at the same time, supports means for receiving the human body load through the cover are disposed forward and backward in the moving direction of the kneading wheels so as to move in conjunction with the kneading wheels. The support means lifts up the human body which has sunk due to the sagging of the cover when moving the ring, and the amount of correction is made smaller than the amount of sagging due to the sagging of the cover. The present invention will be described in detail based on the illustrated embodiment. FIG. 4 shows the appearance of one embodiment, and FIG. 5 shows the state of use.
This pine surge machine configured in a bench shape has legs 41 at both ends.
A cushion section 42 is provided on the top surface of both ends, a side frame 43 is provided on both sides, and a sheet-like cover 6 is provided on the top surface.As shown in FIG. A pair of legs 41 whose upper portions serve as cushion portions 42 are bolted to a frame constructed by connecting both ends of 4 with a horizontal sill 44 and a bottom plate 45, respectively, and a cover 6 and a side frame 43 are attached. There is.

Each frame 4 has a rail 7 with openings facing each other.
7 is fixed to the rail 7, and a hook protrusion 46 is provided on the upper surface of the rail 7.

On the other hand, a core frame 47 is attached to both ends of the fabric cover 6, and a hook hole 48 is provided on both sides. The core frames 47 at both ends are passed through the core frame 44, and the hooking protrusions 46 of the rail 7 are passed through the hooking hole 48, and the core frames 47 on both sides are engaged with the hooking protrusions 46.

At this time, install it with some slack.

The side frame 43 is made by covering the outer surface of a core material 50 with foamed urethane resin 51 and cloth 52, and is fixed to the frame 4 with screws.

A mechanism section provided with kneading wheels 2, 2 for performing pine surge is installed on a pair of rails 7.7 to which racks 8 are respectively fixed along the longitudinal direction.

This mechanism section has a motor and is self-propelled along a rail 7. A motor block 9 is disposed at one end of the main shaft 1 on which the kneading wheels 2, 2 are mounted in the center, and a gear box 10 is disposed at the other end. It is configured as follows.

Guide rollers 17 are freely rotatably mounted on both ends of the main shaft 1, and the guide rollers 17 run within the rails 7.

Further, guide rollers (not shown) that run within the rail T are attached to the gear box 10 and the motor block 9, and the mechanism section is constructed between the rails 7 and 7 by these four guide rollers 17. .

The main shaft 1 is hollow and has a drive shaft mounted therein, and pinions 15 are formed at both ends of the drive shaft to mesh with the rack 8 attached to the rail γ, which drives the drive shaft to rotate. Then, the mechanism section runs along the rail 7.

The main shaft 1 and the drive shaft are selectively driven by a motor in a motor block 9 which is capable of forward and reverse rotation.

5 in FIG. 6 is a side roller.

A pair of kneading wheels 2 are attached to the main shaft 1 at intervals, as shown in FIG. It is configured to be freely rotatable relative to the inner peripheral portion fixed to the main shaft 1.

A U-shaped plate spring 3 made of metal or synthetic resin is connected to a gear box 10 and a motor block 9 at both ends, at the front and rear of the longitudinal direction of movement of the cover 6 by the drive shaft of the kneading wheel 2. By fixing them to each other, they can be placed as a cantilever support.

Each leaf spring 3 serving as a support means is arranged at a lower position than the upper end of the kneading wheel 2, and its free end is curved downward to provide cantilever support and to create a deflection that fits the curve of the human body. I have to.

Therefore, as described above, the cover 6 is slack in the direction perpendicular to the direction of movement of the kneading wheel 2, and for this reason, when the person lies on the cover 6, the human body sinks due to the slack of the cover 6.

However, before and after the massaging process 2, the leaf spring 3 supports the human body load and suppresses the amount of sinking, so that the cover 6 maintains a slack state.

Therefore, when kneading and pine surge is performed by rotationally driving the kneading wheel 2, the slack cover 6 follows the movement of the kneading wheel 2 due to its eccentric inclination as shown in FIG. It directly transmits the movement of the kneading wheel 2 and enhances the pine surge effect, and when moving the kneading wheel 2 to stretch the back, the kneading wheel 2 is positioned at the front and rear of the direction of movement, and the kneading wheel 2 The leaf springs 3, 3, which move in conjunction with the cover 6, first lift the human body, which has sunk down due to the slackness of the cover 6, a little, and then the massaging wheel 2 comes into contact with the human body to push the human body up further. Since the amount of correction is small compared to the amount of insertion, the pillar will not be damaged.

The amount of deflection of the plate springs 3 due to the human body load depends on the load, so even at the waist of the waist, one of the plate springs 3 deflects greatly due to the large load of the buttocks, causing the position of the buttocks and the waist of the waist to change. Since it is set low, sufficient pine surge can be obtained.

The pair of front and rear leaf springs 3 serving as support members may be further divided into a plurality of parts in a direction orthogonal to the moving direction, as shown in FIG.

In this case, as shown in Fig. 10, each leaf spring 3 is deflected to fit the curve of the back of the human body.
This allows you to receive pine surgery in a more comfortable position.

In the above embodiments, a bed-type device is shown, but it goes without saying that a pine surge device built into the backrest of a chair may also be used.

As described above, in the present invention, the support members, which are located at the front and back of the kneading machine in the moving direction and move in conjunction with the kneading wheels, lift the human body by receiving the load of the human body sinking due to the slack in the cover. For this reason, there is slack in the cover near the massaging wheel, and the movement caused by the rotation of the eccentrically inclined massaging wheel is reliably transmitted to the human body through the cover, resulting in pine surge that has the feeling of pushing and squeezing. Moreover, even when stretching the back by moving the massage wheel, the amount of correction by the massage wheel is small because the support member is used to lift the human body in advance, and even though the cover is made to have some slack. , it is safe and does not cause any damage to the human body.
