Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention is a pine surge machine that can move a treatment element, and in particular, a pine surge machine that can move the treatment element in both a rotating mode and a non-rotating mode at the same time. This relates to a pine surge machine that can be configured.

[Background Art 1 Various devices have been provided that can perform pine surgery on various parts of the back of the human body from the waist to the shoulders by moving the treatment element. If you are using a device that performs pine surgery in different ways depending on when it is moved and when it is moved without rotation, the rotational drive of the treatment element is determined by using the engagement between the pinion and the rack. There are some that do not require a dedicated power source for this purpose. In other words, if a rack is arranged along the movement path of the treatment element and the treatment element is moved with the pinion provided on the treatment element meshed with the rank, the treatment element will be rotationally driven and the above-mentioned engagement will be removed. If the treatment element is moved in this state, the treatment element will move without rotating.

In the conventional example with the above configuration, the engagement member installed at the end of the rack pushes out the pinion in the axial direction, which is the direction perpendicular to the engagement direction, as the treatment element moves. However, in this case, in order to prevent the two from interfering when they engage, the rack must have a low toothed part, and therefore the engagement can only be switched at the end of the rack. can be,
Even if one wanted to switch midway, one had to wait for the treatment element to move to the end of the rack, making it impossible to switch at an arbitrary position.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to switch the rotational movement state and the non-rotation movement state of the treatment element by controlling the engagement between the rack and the pinion. To provide a massage machine which can be switched at any position.

[Disclosure 1 of the Invention] The massager according to the present invention is provided with a massager that is movable, and a pinion that engages with a rack disposed along the movement path. In a device in which the treatment element can be freely switched between a rotationally moving state and a non-rotatingly moving state by controlling the engagement between the rack and the pinion, the engagement is controlled by moving at least one of the rack and the pinion in the direction in which they engage. This device is characterized by the provision of a control member.

The present invention will be described in detail below based on the illustrated embodiment.The pine surge machine shown here is built into the backrest of a chair and has a treatment element 6 that is movable in the vertical direction of the backrest. Starting with the chair, the frame 1 of this chair is made of synthetic resin molded so that the backrest and seat are integrated, and it is a bottomed box with an abbreviated side profile and an open front. It is said that And on both sides of the front side of these 7 frames 1, there are body 2
, 2, a seat body 3 is attached to the upper surface of the seat, and a head support body 4 is attached to the upper end.

These receiver bodies 2t3t4 are formed as synthetic resin molded products and are fixed to the 7-frame 1 plate-shaped core material 10, and foamed urethane tilt arranged on the surface of the core material 10.
The backrest is made up of a cushion 11 made of tilt, etc. In the body 2, the backrest is further covered with a surface material 12 such as cloth or leather on the surface of the cushion 11. Both back supports and the space between the bodies 2.2 are covered by a cover 5.

In addition, the bottom surface of the frame 1 has a grounding part 31 whose front end gently rises toward the front end of the seat, a horizontal grounding part 32 in the middle, and an arc-shaped grounding part 33 which rises in an arc toward the rear. A stopper 14 is attached to the arcuate grounding portion 33 and is slidable back and forth. If the stopper 14 is moved forward, that is, toward the horizontal grounding part 32, the chair cannot be swayed, but if the stopper 14 is moved to the rear end of the arcuate grounding part 33, the chair can be swayed. This is how it is. It can also be used as a rocking chair.

A treatment element 6 for pine surgery and a motor 7 for driving the treatment element 6 are housed inside the chair.

The motor 7 is suspended and attached to the lower plate 20 of a lower plate 20 installed at the lower part of the frame 1 and an upper plate 21 installed at the upper part of the frame 1 by a vibration isolating rubber 70. The treatment element 6 is located approximately in the center of the seat, and the treatment element 6 is used for both of the above-mentioned plays)20.
It is provided on a movable block attached to a drive shaft 8 as a feed screw which is installed between 21 via a bearing, and is located inside the backrest. In addition to the drive shaft 8, a rail 9 located in front of the drive shaft 8 and a reinforcing frame 80 that bends both sides and rear of the drive shaft 8 are installed on the above-mentioned two plays. While both the drive shaft 8 and the reinforcing frame 80 are straight, the rail is bent forward at its upper portion and rearward at its lower portion. Furthermore, this rail 9 has a U-shaped cross section that opens only at the rear, and has a lever 90 fixed to its inner surface, and two controls parallel to the rail 9. Links 91.91 are connected.

Each control link 91 has its upper and lower ends connected to the link 9, respectively.
By being connected to the rail 9 by 2.92,
The rail 9 and both links 92 and 92 constitute a four-bar mechanism, whose upper end is connected to a solenoid 93 fixed to the upper plate 21 by a wire 94, and whose lower end is shown in FIG. It is pulled toward the lower plate 20 by the tension spring 95. In this case, the control link 91 is close to the rail 9 when it is pulled downward, and moves away from the rail 9 when it is pulled upward.

The lower end of the movable block equipped with the treatment element 6 is connected to the motor 7.
By rotating the drive shaft 8 connected by a belt 71, the rack 9 moves up and down along the rail 9.
A feed nut body 60 that is rotationally driven by meshing with the feed screw 8 and screwed with the drive shaft 8 that is a feed screw, a pair of arms 61 whose one end is pivotally supported by the feed nut body 60,
61, consists of a shaft 62 etc. held at the other end of both arms 61.61, and the treatment element 6 is a pair of roller plates welded and fixed to the shaft 62 on both sides of the rail 9) 65.65 and both roller plates 6
A roller 66 is freely rotatably attached to each tip of the radial projection in 5 via a pongee 67 and a roller bearing 68.
It is composed of.

As shown in FIG. 2, the feed nut body 60 further surrounds the outer surface of a reinforcing frame 80, which has a U-shaped cross section and surrounds the drive shaft 8 to which it is screwed, and the inner surface of the reinforcing frame 80. and a guide roller 83 that moves around the rear surface of the reinforcing frame 80. The shaft 62 is provided with a spline or a key in its center, and a pinion 64 is attached to rotate together with the shaft 62, and guide plates are provided on both sides of the pinion 64.
) 74.74 are attached via presser springs 73.73. Further, guide rollers 76 and 76 are attached to both ends of the shaft 62.

The pinion 64 meshes with a rack 90 fixed to the rail 9, and both are id play) 74.
74 rolls on the front surface of the rail 9 to support the load applied to the treatment element 6, and the idle roller 78 is supported by a shaft 77 passed between its tips. The other end of a torsion coil spring 79, which is attached to the outer periphery of the shaft 62 and whose one end is locked to the arm 61, is locked to the id play. Torsion coil spring 7
9 urges the shaft 62 against the feed nut body 60 in a direction to press it against the rail 9 side. As shown in FIG. 3 or FF14, a pair of presser springs 73 and 73 formed of leaf springs are respectively locked at both ends to the idle plate 74 and hold the shaft 62 in the center. This pulls the guide plate 74 against the shaft 62. The guide rollers 76, 76 are located at a distance in front of the rail surface 19 formed on the frame 1.

The pair of control links 91.91 are located on the front side of the shaft 62, that is, on the rail 9 side, on both sides of the control links 91.91.
It is said that it can be transferred or slid into contact with the back side of the body.

The treatment child 6 is, as mentioned above, a pair of roller plays)
65.65, and a roller 66 which is freely rotatably attached to each tip of the radial projection of both roller plates 65 via a shaft 67 and a roller bearing 68! i,
The roller 66 is one roller.
Four to six pieces are provided at equal intervals on the outer circumference of the plate 65.

In this massage machine configured as above,
When the drive shaft 8 is rotated by the motor, the movable block in which the feed nut body 60 is screwed onto the drive shaft 8, which is a feed screw, moves up and down as the drive shaft 8 rotates. At this time, the treatment element 6 also moves up and down, and the torsion fill spring 79 and presser spring 73 (
The pinion 64 is biased so that it moves up and engages with the rack 90, but when the hunt roll link 91 is close to the rail 9, the pinion 64 engages with the rack 90 as shown in FIG. The pitch distance between the pinion 64 and the rack 90 is maintained by the idle roller 78 and the control link 91. However, when the control link 91 is separated from the rail 9, the shaft 62 is pushed against the control link 911 and becomes separated from the rail 9 against the spring bias, as shown in FIG. The pinion 64 and the rack 90 are not engaged with each other.

The movement of the control link 91 moves the pinion 64 in the direction of engagement with the rack 90, thereby controlling the engagement between the pinion 64 and the rack 90.

In the former case, the pinion 64 rotates due to engagement with the rack 90 as the movable block moves up and down,
The treatment element 6 is rotated around the axis of the shaft 62 via the shaft 62. For this purpose, each roller 66 located on the outer periphery of the roller plate 65 sequentially presses the back of the human body through the cover 5, and at this time, two rollers 66 are in contact with the back of the human body. States in which only one roller 66 is in contact with the back of the human body appear alternately, and in the two states, the distance of the roller 66 from the rail 9 at the time of contact with the human body is different, so the difference between the two distances is Differential acupressure pressure is applied to the human body, and this pine surge is performed along the back muscles of the back of the human body, resulting in ``continuous pressure'' pine surge. In the latter case, the treatment element 6 is placed on the rack 90.
Since the treatment element 6 is separated from the rollers 6, it is in a free state, and as a result, the treatment element 6 is separated from the two rollers 6, which are in a stable state.
6 is in contact with the inner surface of the cover 5, only the vertical movement is corrected. Since the two rollers 66 that are in contact with the human body through the cover 5 move while rotating freely, "rolling" pine surgery is performed. The front surface of the rail 9 supports the human body via the cover 5 in areas where the treatment element 6 is not located, and serves to prevent the human body from sinking, but the presence of the cover 5 alone at the opening may cause pain. A cushion portion 58 is provided on the back side of the central portion of the cover 5 in the width direction.

The engagement may be controlled by moving the rack 90 instead of the pinion 64.

Examples in this case are shown in FIGS. 6 and 7. The difference from the above embodiment is that the rack 90 is not fixed to the rail 9, but has the same configuration as the control link 91, so that a state close to the rail 9 or a state separated from the rail 9 can be selected. and that one end of the plate 74 is directly connected to the shaft 62 so as to freely rotate. When the rack 90 is brought close to the rail 9, the pinion 64 and the rack 90 do not mesh, and the rack 90 is separated from the rail 9 and the pinion 6
When approaching 4WI, the rack 90 and pinion 64 engage. Note that the distance between the rail 9 and the shaft 62 is
It is kept constant by providing a portion on the side plate 74 that slides against the back surface of the rail 9.

FIG. 8 shows the control circuit C. This control circuit C, which is formed by a one-chip microcomputer, includes a timer circuit CT and a cutout circuit CC, as well as an operation switch SW installed on the side of the frame 1, a position detection sensor 55, a power supply circuit D, and a motor drive. A circuit MD, a solenoid drive circuit SD, etc. are connected. Position detection sensor 55
As shown in FIG. 1, a belt 50 is stretched between pulleys 53 and 54 attached to a lower plate 20 and an upper plate 21, and is connected to a feed nut body 60 via a tension spring 51. It is designed to optically detect a small hole provided in the sensor.

Note that the small holes provided in the belt 50 are provided corresponding to the positions where the vertical movement direction of the treatment element 6 is to be reversed.

When a command to change the type of pine surge is not received from the operation switch SW, the control circuit C is configured so that the treatment element 6 is
Each time k (XIWX2 in FIG. 9) is reached, a command is given to the motor drive circuit MD to reverse the rotational direction of the motor 7, thereby continuing the rubbing or continuous pressing of the pine surge. When a command to change the pine surge type is received, the control circuit C immediately switches the solenoid drive circuit SD.
By controlling the solenoid 93 via the solenoid 93, the foot roll link 91 or the rack 90 is moved to change from rasping to continuous pushing, or from continuous pushing to rasping pine surge.

[Effect of the invention 1 As described above, in the present invention, since the meshing is controlled by moving either the rack or the pinion in the direction in which they mesh, it is possible to change the type of pine surge. The meshing control can be performed at any position within the movement range of the treatment element, which makes it easy to use and has a good feeling of use.
