Description

[Detailed description of the invention] The present invention is configured so that rolling pine surge and vibration pine surge are applied at the same time during pine surge, and the presence of the rolling pine surge roller and the vibrating pine surge child is controlled by the backrest while the pine surge operation is paused. It can be used as a regular easy chair without feeling stiff, and while using it as an easy chair, you can listen to your favorite music not only during pine surgery, but also during pine surgery.It relieves mental tension, allows pine surgery to be performed in a relaxed state, and reduces fatigue. The purpose is to provide a pine surge machine that is effective for recovery.

In recent years, a chair-type electric pine surger has been developed in which a pine surge roller is reciprocated inside the backrest along the height of the backrest, and the pine surge roller performs pine surge on the back of the human body from the lumbar region to the back of the head. Machines have come to be preferred and used for general purposes. However, in this type of pine surge machine, the pine surge roller moves substantially along the inner surface of the top sheet of the backrest,
Since the pine surge is applied to the human body through the surface sheet, the position of the pine surge roller will be felt by the human body no matter which position it is at rest. This has the disadvantage that it hinders the comfortable cushioning of the backrest.

The present invention improves the above-mentioned disadvantages by lowering the pine surge roller to the lowest position when the pine surge action is at rest, and moving the pine surge roller away from the top sheet of the backrest, thereby increasing the presence of the pine surge roller when used as an easy chair. The present invention provides a pine surge machine that can be used without any problems.

Another purpose of this invention is to listen to your favorite music from your preferred direction while undergoing pine surgery to relieve tension in your mind and body, thereby increasing the effect of pine surgery. To provide a chair-type electric pine surge that allows you to enjoy a comfortable rest while listening to music in a chair that does not make you feel the presence of the pine surge roller.

The drawings showing embodiments of the present invention will be described below.

Figure 1 is a perspective view of a chair-type electric pine surgery machine, and Figures 2 and 3 are schematic illustrations of the main parts of the pine surgery device inside the backrest of the pine surgery machine. Pulleys 3 and 4 are rotatably supported in the upper and lower parts of the backrest 2, and an endless belt 5 is spanned between the pulleys 3 and 4, and a reversible motor 6 and a deceleration machine 7
It is configured to be rotationally driven through the
8 is a plate fixed to the belt 5;
Reference numerals 9 and 9 denote arms whose one end is rotatably supported by the plate, and between the other ends of the arms 9 and 9, rolling pine surge rollers 10 and 10 are connected to a roller shaft 11.
This rolling pine surge roller 1
0 is elastically biased by a tension spring 13 so as to move up and down along the guide rail 12. 1
4 is a guide roller that is in sliding contact with the guide rail 12; 15 is an arm whose one end is rotatably supported on the shaft 11; a vibrator 16 is mounted at the lower end of the arms 15, 15; A spring 18 is mounted between the vibrator 16 and the plate 8 on the roller shaft 11, which biases the vibrator 16 toward the backrest cloth 17. As is already well known, the vibrator 16 has a small motor built into the case and an eccentric weight attached to the rotating shaft of the motor.

Next, the upper and lower horizontal plate portions 2 of the U-shaped support fittings 19 are fixed to both sides of the upper end portion of the backrest portion 2.
Between 0 and 21, upper and lower horizontal plate parts 24 of U-shaped rotating fittings 23, 23 fixed to movable plates 22, 22,
25 is inserted into the rotating metal fitting 2 through a shaft 26 that can pass through the upper and lower horizontal plate parts 20, 21 of the support metal fitting 19 and the upper and lower horizontal plate parts 24, 25 of the rotating metal fitting 23.
3 and 23 are rotatably supported, and a plurality of recessed holes 27 are provided on the circular locus of the horizontal plate part 21 under the support fitting 19 centered on the shaft 26, A protrusion 2 that engages with and disengages from the recessed hole 27 on the horizontal plate portion 25
8, and a spring washer 29 is interposed between the horizontal plate portion 20 on the support metal fitting 19 and the horizontal plate portion 24 on the rotation metal fitting 23 to bias the rotation metal fitting 23 downward. The horizontal plate portion 24 above the rotating fitting 23 is provided with a female thread 31 that is screwed into the threaded portion 30 of the shaft 26, and by rotating the shaft 26, the fitting state of the protrusion 28 in the recessed hole 27 and the support The contact state of the horizontal plate part 25 under the rotating metal fitting 23 with the horizontal plate part 21 under the metal fitting 19 can be adjusted to be strong or weak. Note that the female screw 31 may be provided on the upper and lower horizontal plate sections, or on either one of them, and the lead angle of the screw is preferably a small lead angle so that the rotation of the rotating fitting can be easily adjusted. . Reference numeral 32 represents a speaker attached to opposing surfaces of the movable plates 22, 22, and reference numeral 33 represents a recording/reproducing apparatus main body into which a cartridge type or cassette type pack containing a recording medium is inserted in a replaceable manner.

Since the present invention has such a structure, by appropriately switching the rotation of the reversible motor 6 between forward and reverse directions, the belt 5, which is endlessly installed between the upper pulley 3 and the lower pulley 4, is rotated clockwise. Alternatively, it rotates counterclockwise, whereby the rolling pine surge roller 10 reciprocates from below to above and from above to below, applying rolling pine surge to the back of the body. In the present invention, at the same time as the pine surge by the rolling pine surge roller, vibration pine surge is simultaneously applied by the vibrator 16 connected to the roller shaft 11 of the rolling pine surge roller via the arm 15. Furthermore, the rolling pine surge by the rolling pine surge roller does not simply involve rolling pine surge of the back by the roller, but also involves the vibrator 16 being connected to the roller shaft 11 of the rolling pine surge roller 10 via the arm as described above. Therefore, the vibration of vibrator 16 is caused by arm 1.
5. It is transmitted to the rolling pine surge roller 10 via the roller shaft 11, furthermore, the spring 18, etc., and the roller 10 performs rolling pine surge while vibrating slightly, resulting in better pine surge than ever before. In addition, since the lower end of the guide rail 12 is bent backward, the rolling pine surge roller 10 and the vibrator 16 can be comfortably used as an easy chair because they do not come into contact with the human body, as shown by the two-dot chain line in FIG. be able to. In the drawings of the first embodiment, the rolling pine surge roller and the vibrator are attached to a belt and moved up and down, but they may be moved up and down using a chain. Furthermore, when the movable plate 22 is rotated with the shaft 26 tightened to an appropriate state that allows the movable plate 22 to rotate, the protrusion 28 protruding from the horizontal plate portion 25 below the rotation bracket 23 will move to the support bracket 19. The three recesses 27 provided in the lower horizontal plate portion 21 are engaged with and disengaged to move the speaker 32 from an inward position perpendicular to the backrest (shown by the chain line in FIG. 4) to an outward position ( Fourth
The opening angle of the movable plate can be changed in stages to (shown by the solid line in the figure). Therefore, while sitting on a chair, each person can adjust the opening angle of both movable plates 22, 22 at the upper end of the backrest relative to the backrest in three steps, and each person can adjust the direction in which the sound comes from the speakers, such as from both sides of the ear or diagonally behind the ear. Adjust to suit your tastes,
It is extremely effective in terms of the effect of pine surgery because it can relax the mental state and apply pine surgery to areas of the body that have stiffness. Further, the shaft 26 is tightened to move the rotating fitting 23 downward via the female threaded portion 31 screwed into the threaded portion 30 of the shaft 26, and the protrusion 28 is firmly fitted into the specific recessed hole 27. At the same time, when the lower surface of the horizontal plate part 25 under the rotating metal fitting 23 is pressed against the upper surface of the horizontal plate part 21 below the supporting metal fitting 19, the rotating metal fitting 23 becomes fixed, so that the movable plate 22 is moved into a predetermined position with the backrest part 2. You can set the device to listen to your favorite music only from a specific direction that suits your preference, and receive a relaxing massage that is effective for recovering from fatigue. .
