Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chair-type pine surge machine, which enables two types of reclining forms for pine surge, and is configured so that each form can be used properly as necessary. This relates to a chair-type pine surge machine.

[Background of the invention]

The reclining form of the conventional chair-type pine-surgery machine was such that only the backrest part was reclined and used almost like a bed, as shown in Fig. 6, which will be described later. You can relieve tension and feel relaxed during the treatment, and since your weight is applied to the massaging area on the backrest, even stronger pine surge force is added, especially,
While it has the advantage of effectively acting on the back and shoulders, in order to shift to this form, you have to change your body posture from the normal sitting position, which is accompanied by a certain degree of resistance. When the backrest is in contact with the backrest and the back of the torso that comes into contact with it, a certain amount of relative positional deviation occurs, so the position of the body must be corrected. Although it brings about the effective treatment effect on the lower back area as described above, it has various drawbacks such as the lower back area being relatively easy to evacuate and therefore not being very effective in the pine surge effect around the lower back area.

[Purpose of the invention]

In view of the above-mentioned drawbacks of the reclining form of the prior art, the present invention adds a new reclining form that solves these problems, and provides a chair-type pine surgery machine that can be used for different purposes as needed. The purpose of this invention is to provide a reclining mechanism.

The main point of the present invention is that although the reclining form of the conventional chair-type pine-surge machine has various drawbacks as mentioned above, it has irreplaceable advantages that cannot be replaced by anything else. Accordingly, in the present invention, as an ideal chair-type pine surger, the reclining mechanism has a configuration that allows the conventional reclining form to remain as is, and a new form that solves the drawbacks, that is, the backrest part and This is a chair-type pine surge machine that has a structure that allows a new reclining form to be added in which the seat part can be reclined integrally to a certain angle, and that these two types of reclining forms can be used separately as necessary. It's in the reclining mechanism.

〔Example〕

Next, embodiments according to the present invention will be described with reference to the respective figures.

Here, FIG. 1 is a perspective view of a roller pine surgery machine as a specific example of a chair-type pine surgery machine equipped with a reclining mechanism according to an embodiment of the present invention, and FIG. 2 is a perspective view of the reclining mechanism of the chair-type pine surgery machine. 3 and 3 are enlarged perspective views of the main parts, FIGS. 4 and 5 are perspective views showing respective reclining forms, and FIGS. 6 and 7 are views of the treatment state using the chair-type pine massage machine.

First, the chair-type pine surge machine shown in Fig. 1 has a backrest part 1, which is built into the backrest part 1 and has functions such as vertical movement, massaging, and pushing.
2 pairs of massage balls 2 for performing pine surgery on the shoulders, lower back, etc.
a, 2b, a seat part 3, seat parts 4a, 4b, a leg frame 5, a reclining operation lever (hereinafter simply referred to as the operation lever) 6, a reclining switching operation part (hereinafter simply referred to as the switching operation part) 7, etc. It is something.

The reclining mechanism is as shown in FIG.

That is, first, the backrest frame 8, which forms the skeleton on which the backrest part 1 to be subjected to the roller pine surge is to be attached, the seat frame 9, on which the seat part 3 is to be placed;
It is formed by a connecting rod 10 that integrally connects the backrest frame 8 and the seat frame 9, a shock absorber 11 that performs reclining, and the like.

The backrest frame 8 and the seat frame 9 are each rotatably connected to a pin 12a,
12b etc., it is integrally supported by supports 13a and 13b provided on both sides of the leg part consisting of the leg frame 5, and the connecting rod 10 is provided with one end supported by the seat frame 9. The other end is rotatably supported on the transfer beam A14, and the other end is connected to the transfer beam B provided below the backrest frame 8.
15 so that it can be connected to and removed from it.

As clearly shown in FIG. 3, the engagement portion of the connecting rod 10 can be attached and detached by attaching one end to a bearing plate 17 provided on the bridge beam C16 bridged by the leg frame 5, and attaching the other end to the leg frame 5. This is carried out using L-shaped operating rods 19 that are each pivotally supported by an operating panel 18 provided on the outside of the control panel.

That is, as shown in FIG. 3, when the operating rod 20, which is integrally provided at the tip of the operating rod 19, is manually rotated as shown by the solid arrow in the figure, the operating rod 19 rotates as the operating rod 19 moves, and the tip of the operating rod 19 rotates. The portion 21 abuts and lifts the connecting rod 10, and the engaging portion of the connecting rod 10 is disengaged from the transfer beam B15, as shown by the two-dot chain line in the figure.

Conversely, when the operating shaft 20 is pushed down in the direction opposite to the direction of the arrow above from this state, the tip 21 also rotates in the direction opposite to the direction of the arrow and separates from the connecting rod 10, and the connecting rod 10 rotates due to its own weight. It falls down and is engaged with the transfer beam B15.

The operating rod 20 is provided with a lock knob 22 that moves in the direction of the dotted line arrow shown in the figure, and at the same time, the shaft thereof faces the guide groove 23 of the operating panel 18 so as to be movable. The connecting rod 10 is configured to be locked by hooking the shaft to the stopper portion 24 of the connecting rod 10, so that the connecting rod 10 can be held in the disengaged state, that is, the state shown by the two-dot chain line in the figure. It is.

As described above, the above-mentioned engagement between the connecting rod 10 and the connecting beam B15 is performed when the backrest frame 8 is normally upright, that is, when it is not reclined and the position of the connecting beam B15 matches the engagement part of the connecting rod 10. In other cases, the abdomen of the connecting rod 10 is simply placed on the transfer beam B15 without being engaged.

Further, the shock absorber 11 is installed between the transfer beam B15 and the transfer beam C16,
By pushing down the operating lever 6 mentioned earlier, the lock by the normal locking mechanism is released.
The backrest frame 8 is designed to be freely rotatable around the support portion mentioned above. In other words, this has a general configuration and always acts in the direction of raising the backrest frame 8, but if you release the lock and add your weight, you can resist the spring force and tilt the backrest frame 8, and the weight will rise. If you remove it, it will automatically return to its original state.

Note that the operation panel 18, operation rod 19, operation rod 20, etc. described above form an operation section.

Next, the operation of the reclining mechanism configured as described above will be explained.

First, as shown in FIG. 4, rotate the operating rod 20 to lock the lock knob 22, and then
When you press down, the transition beam B15 of the connecting rod 10
At the same time, the lock of the shock absorber 11 is released, and the backrest frame 8 can be tilted to an angle commensurate with the stroke of the shock absorber 11.

This is the operation corresponding to the conventional reclining configuration.

On the other hand, as shown in FIG. 5, when the operating rod 20 is unlocked and the operating lever 6 is pushed down, the shock absorber 11 is unlocked and the backrest frame 8 can be folded down. The seat frame 9 is connected to the connecting rod 10.
Moreover, the connecting rod 10 serves as a pillar, and the seat frame 9 can be rotated at the same time.

This is the operation according to the new reclining configuration according to the present invention.

Therefore, FIGS. 6 and 7 show the state of treatment by the chair-type roller pine surgery machine using the above-mentioned reclining mechanism, that is, the one shown in FIG. 1. In addition, in each figure, the armrest part 4
A and 4b are omitted from illustration.

That is, FIG. 6 shows the treatment state of the human body in the reclining mode of operation A described above, and FIG. 7 similarly shows the treatment condition of the human body in the reclining mode of operation B.

First, in FIG. 6, the inclination angle θ ₁ of the backrest portion 1 is generally about 10 degrees. Therefore, the stroke of the shock absorber 11 mentioned earlier is determined to be a stroke commensurate with this.

Furthermore, the inclination angle θ ₂ of the backrest portion 1 in FIG. 7 is approximately 40° when considering the balance of the center of gravity of the human body.
Although not shown in the drawings because it is desirable that the height is higher than that, a stopper for regulating the inclination of the backrest 1 can be used to prevent it from falling below that range.

In addition, the reclining form in Fig. 6 is as follows.
The reclining state shown in FIG. 7 is performed by forcing the upper body to fall down by stretching the right arm on the armrest 4b mentioned earlier, but in both cases, the reclining state shown in FIG. The return to the normal original state is automatically performed by the repulsive force of the shock absorber 11 mentioned above.

[Effect]

In the chair-type roller pine serge machine using the reclining mechanism described above, in particular, according to the new reclining method as shown in FIG. Like a rocking chair, the user can move straight from the sitting position, and can perform reclining pine surges smoothly and without any trouble. At the same time, this can be done without any relative displacement between the backrest portion 1 and the back surface of the upper body.

In addition, since the weight of the whole body in this state is almost concentrated in the lower back, the lower back is strongly contacted by the massaging balls 2a and 2b, and is also pushed deeply into the valley between the backrest part 1 and the seat part 3. The lumbar region does not escape during treatment, and therefore, a strong and effective pine surge effect can be expected especially when the lumbar region is to be concentrated.

Furthermore, the integral reclining of the backrest part 1 and the seat part 3 can be performed steplessly from the normal sitting position to θ ₂ ≒40 degrees in the case of the above-mentioned embodiment. This inclination angle θ ₂ can be arbitrarily selected to change the weight applied to the lower back, adjust the degree of bite of the lower back, and adjust the pine surge force in that area, which is not achieved with conventional technology. It can bring about many effects.

In addition to the above, the device using the above-mentioned embodiment can be used in a conventional almost bed-type reclining mode by using the switching operation section 7, and each can be used in a reclining mode according to the user's preference. It has extremely remarkable effects, such as being able to effectively select and utilize the characteristics possessed by people.

Taking all the above into account, the present invention provides a chair-type pine massage machine that can arbitrarily select between two reclining modes: the conventional reclining mode and a new reclining mode in which the sitting posture is transferred as it is. This invention can provide a reclining mechanism, and can be said to greatly contribute to pine surgery treatment for the human body.
