Description

[Detailed Description of the Invention] The present invention relates to an improvement of a chair-type electric pine surgery machine.

The parts of the back of the human body, excluding the eyebrows and waist, have skeletons close to the skin surface, so it hurts when pressure is applied, but the shoulders and lower back are covered with muscles, so you don't feel much pain when you apply pressure. When the pine surge pressure from the massage ball is kept constant, the shoulders and lower back do not feel much pine surge force.

Therefore, the same pine surge pressure is applied to the backrest area, that is, the massage ball acts strongly on the skin and waist area, and the massage ball acts weakly on other areas, providing a comfortable pine surge effect for the user. The present invention is intended to provide a pine surge machine with a simple configuration.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.
Fig. 1 is a partially sectional side view of the pine surge machine according to the present invention, in which 1 is a backrest, 2 is an armrest, and the backrest 1 is provided on the left and right armrests 2, 2. It is tiltably supported on reclining fulcrum shafts 3, 3.

Reference numeral 4 designates a seat portion, and this seat portion 4 is placed on support plates 5, 5 attached to each of the armrest portions 2, 2.

Inside the backrest portion 1, as shown in FIG. 2, one screw shaft 6 and two pillars 7, 7 curved in a curve matching the shape of the dorsal vertebrae of the back of the human body are erected and fixed. ing.

These screw shafts 6 and pillars 7 extend in the vertical direction of the internal space 8 of the backrest, and are erected between a flat metal plate 9 attached to the upper inner surface of the backrest 1 and a gate-shaped frame 10 provided on the lower inner surface. ing.

A reversible motor 11 for lifting and lowering is attached to this portal frame 10, and a driving pulley 12 is fixed to the rotating shaft 11a of the motor 11, while a driven V pulley 13 is fixed to the lower end of the screw shaft 6. , V between each of these V boos 912 and 13
The rotational force of the motor 11 is applied to the rotation shaft 11 by stretching the belt 14.
a, V pulley 12, V belt 14 and V pulley 13
The signal is transmitted to the screw shaft 6 in this order.

Further, an elevating bracket 15 is screwed onto the screw shaft 6, and a movable flat plate 16 is screwed onto the front surface of the bracket 15.

Therefore, the movable flat plate 16 together with the lifting bracket moves up and down reciprocally as the screw shaft 6 rotates.

This movable flat plate 16 has two protruding rods 17.1 at the top.
7 and two protruding rods 18, 18 are also provided protruding from the lower part.

Reference numeral 19 denotes a kneading ball drive device for kneading and beating the pair of kneading balls 29, and since this drive device is already known, it is not shown.

A support plate 20 is attached to the rear side of the drive device 19, and bearing portions 21, 21, 22, 22 of the rods 17, 18 are provided on this support plate 20.

The drive device 19 is driven by a pine surge motor 23.

Reference numerals 24 and 24 denote rotary plates which are pivotally connected to the driving device 19, respectively, and a pair of support supporting rollers 25 and 25 are rotatably supported on the outside of these rotary plates 24 and 24, respectively.

The driving device 19 and the support plate 20 are configured to move up and down along the left and right supports 7, 7 while the respective pairs of rollers 25, 25 sandwich the support posts 7.

As shown in FIG. 2, an upper limit switch 26 and a lower limit switch 27 are installed in the interior space 8 of the backrest, and a drive device 19 and massage balls 29, 29
The upper and lower limit positions are set.

Further, on the front surface of the backrest 1, a double-structured seat 28 is provided with a slippery and abrasion-resistant synthetic resin cloth on the inside and leather on the outside.

The present invention is constructed as described above, and its operation will be explained below.

Now, when driven together with the two motors 11 and 23, the lifting bracket 15 and the movable flat plate 16 move up and down in either direction due to the rotation of the screw shaft 6, so that the flat plate 16 has four protruding rods 17, 17, 18, 18. Support plate 2 connected via
0 and the drive device 19 attached to this support plate 20 move up and down in the same direction as the movable flat plate 16, and apply a pine surge effect of kneading or pounding to the user's back via the seat 28.

Here, the support plate 20 and the drive device 19 are raised and lowered with the support column 7 held between a pair of left and right rollers 25 and 25 having a force of 5.

Therefore, when the massage ball 29 moves from the user's back to the shoulder or waist, the support plate 20 moves from the protrusion attached to the movable flat plate 16 to the front together with the drive device in the horizontal direction. , the support plate 20 and the drive device 19 are pushed forward along the support column 7, and the massaging balls 29 act strongly on the shoulders and waist of the user.

Conversely, when the kneading ball 29 moves from the user's shoulders or waist to the back, the support plate and drive device retreat in the opposite direction along the protrusion to provide support. Since the plate 20 and the drive device 19 are retracted inwardly into the backrest 1 along the support column 7, the massaging balls 29 are placed on the user's back.
It acts weakly.

Furthermore, since the rollers 25, 25 are rotatably supported by the rotary plate 24, they smoothly move up and down along the curved support 7 while maintaining a state in which it is elastically held therebetween.

That is, it moves up and down smoothly along the support column 7 by the rotation of the rotating plate 24, the rotation of the roller 25, and the elasticity of the roller 25.

Next, when the pine surge motor 23 is stopped and only the elevating motor 11 is driven, the massaging balls 29 do not perform kneading or tapping, so the massaging balls 29 move up and down while rotating, allowing the user to massage the back. A rotating rubbing effect is given by the ball.

Moreover, as described above, the rubbing effect of the massaging balls 29 is strong on the shoulders and waist of the user, and weak on the back.

The backrest part 1 uses the reclining fulcrum shaft 3 as a fulcrum.
When the massage ball 29 is tilted backward as shown by the imaginary line in FIG. 1, the weight of the user is applied to the massaging balls 29, so that an even stronger pine surge effect can be obtained.

As described in detail above, the present invention allows the drive device to move up and down along the column smoothly, and the massaging balls act strongly on the shoulders and waist, while acting weakly on the back, making it comfortable for the user. It can give a pine surge effect.
