Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a pine massage machine, particularly a treatment element which is driven to run along a human body support table and which can be freely selected between two states: a rotating running state and a non-rotating running state. This relates to a pine surge machine equipped with.

[Background technology] There are many massage machines that massage the body along the spine by moving a treatment element along the back of a chair or a bed to support the body. If only, the operation will be monotonous and the pine surge effect will be weak. For this purpose, the treatment element is made of a radial arm with rollers attached to each end, and two states are selected: a state in which the treatment element travels while rotating, and a state in which it travels without rotation. It has been proposed that this can be done. In this case, by running the treatment element while rotating, you can obtain a "continuous push" pine surge in which each roller presses the human body in turn, and by rotating the massager
5 songs in the middle line 3+nwa 1. Since it is possible to obtain Pak-no and different types of pine surgery, it is possible to obtain more effective pine surgery, and it is also possible to perform this with a single treatment device. It has become. However, when the user is not aware of the switching between the two types of pine surge, the user may get muscle pain or get surprised due to the switching between the types of pine surge.

[Object of the Invention] The present invention was made in view of such fish, and its purpose is to enable the user to reliably recognize the change in type of pine serge; The goal is to provide a pine surger that will not cause muscle pain or shock.

[Disclosure of the Invention] The present invention provides a pine surgery machine equipped with a treatment element that is driven to run along a human body support table and that can be freely selected between two states: a rotating running state and a non-rotating running state. The device is characterized in that means for switching between the two states of the treatment element are provided at both ends of the movement stroke of the treatment element, and a control means is provided for repeatedly moving the treatment element within a small range at both ends of the movement stroke. When the type of pine surge is changed, the treatment element moves repeatedly within a small range to suggest to the user that the type of pine surge should be changed.

The present invention will be described in detail below based on the illustrated embodiment.The massage device here has a treatment element built into the backrest of a rocking chair type chair. The 7-frame chair 1 has a backrest and a seat that are formed by molding synthetic resin into one body, with a recess in the front, and backrests on both sides of the front. 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 of the seat. The bodies 2, 3.4 of each of these supports include a plate-shaped core material 10 which is a synthetic resin molded product and is fixed to the frame 1, and a cushion IJ made of foamed urethane resin or the like arranged on the surface of the core material 10. The backrest is made up of a cushion 11 on the body 2.
The surface is further covered with a surface material 12 such as cloth or leather, and the entire body 2, 3.4 of each of these supports and the opening of the body 2.2 of both back supports are covered with a cover 5. . The bottom surface of the frame 1 has an arcuate grounding section 31 whose front end rises toward the front end of the seat, and a horizontal grounding section 32 at its middle.
The rear end portion is an arcuate grounding portion 33 that rises in an arc backwards, and a stopper 14 that is slidable back and forth is attached to the arcuate grounding portion 33. Move the stopper 14 forward, that is, the horizontal grounding part 3
If you move it to the second side, you will no longer be able to rock the chair.
If the stopper 14 is moved to the rear end of the arcuate grounding portion 33,
The chair can be rocked, in other words, it can 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 a lower plate 2O of a lower plate 20 installed at the lower part of the 7-frame 1 and an upper plate 21 installed at the upper part of the 7-frame 1 by a vibration-proof rubber 70. 20. The treatment element 6 is located approximately in the center of the seat.
It is provided in a movable block attached to a drive shaft 8, which serves as a feed screw, and is located within the backrest portion, which is installed between the two parts 21 through a bearing. In addition to the drive shaft 8, a rail 9 located in front of the drive shaft 8 and a reinforcing frame 80 surrounding both sides and rear of the drive shaft 8 are installed between the two plates 20 and 21.

While the drive shaft 8 and the reinforcing frame 80 are both linear, the rail 9 is bent forward at its upper portion and rearward at its lower portion. Further, some of the rails 9 have a U-shaped cross section that opens only toward the rear, and a rack 90 is fixed to the inner surface of the rail 9.

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. It consists of a shaft 62 held at the other end of both arms 61.61, and the treatment element 6 is a pair of roller plates (65, 65) welded and fixed to the shaft 62 on both sides of the rail 9. and both roller plates 6
A roller 66 is freely rotatably attached to each tip of the radial projection in 5 via a shaft 67 and a roller bearing 68.
It is composed of.

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. It is equipped with an idler roller 83, which moves the rear of the vehicle. The shaft 62 has a spline 63 in its center.
Alternatively, a key or the like is provided, and the pinion 64 is attached to be slidable in the axial direction and rotated together with the shaft 62, and guide disks 73 and 73 are freely rotatable on both sides of the spline 63. Furthermore, guide plates 74 and 74 are attached to both sides of the shaft 62 via bearings 75, and narrow rollers 76 and 76 are attached to both ends of the shaft 62.

The above-mentioned pinion 64 meshes with a rack 90 fixed to the rail 9, so that it can be used on both sides.74.
Reference numeral 74 supports an idle roller 78, which rolls on the front surface of the rail 9 and supports the load applied to the treatment element 6, by a shaft 77 passed between its tips. Further, 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 latched to the arm 61, is latched to the guide plate 74.74. The torsion coil spring 79 biases the feed nut body 60 in a direction to press the shaft 62 toward the rail 9 side. Said double id discs 73.7 located on both sides of the binion 64
3 is located along the opposing inner surfaces of both side pieces of the rail 9, and by bringing the outer peripheral edge into contact with the rail 9, determines the engagement pitch between the binion 64 and the rack 90,
This prevents interference between the two meshes, and also prevents the binion 64 from coming into contact with the bottom surface of the rail 9 due to the bias caused by the torsion coil spring 79 when the rack 90 and the binion 64 are disengaged, which will be described later. . Guide rollers 76 and 76 at both ends of the shaft 62 are located at intervals in front of the rail surface 19 formed on the seven frames 1.

Next is the treatment element 6, which, as mentioned above, consists of a pair of roller plates 65, 65 and both roller plates 65.
It is composed of a pongee 67 and a roller 66 freely rotatably attached to each tip of the radial protrusion through a roller bearing 68, and the roller 66 is attached to the outer part of one roller plate 65. 4 to 6 are provided at intervals.

In this Pine Sage Iso configured as described above,
When the drive shaft 8 is rotated by the motor 7, 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 is urged by the torsion coil spring 79 to engage with the rack 90, and at the same time, the treatment element 6 also moves up and down.
The pinion 64, which is guided by the j-id disk 73 to maintain the pitch distance, slides in the axial direction with respect to the shaft 62, and is engaged with the rack 90 as shown in FIG. As shown in FIG. 7, there are two states, a state in which the movable block is not engaged and a state in which it is not engaged. Treatment child 6
is rotated around the axis of 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 twelve states, the distance of the roller 66 from the rail 9 at the time of contact with the human body is different, so the two distances are different. Acupressure pressure is applied to the human body, and this pine surge is applied along the spine on the back of the human body.
It is a pine surge of "continuous press". In the latter case, since the treatment element 6 is separated from the rack 90, the
As a result, the treatment element 6 moves only up and down with the two rollers 66 in a stable state in contact with the inner surface of the cover 5. 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 through 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 in between only prevents pain. A cushion portion 58 is provided on the back side of the central portion of the cover 5 in the width direction.

Now, the switching means for controlling the engagement between the rack 90 and the pinion 64 is an id bone 15 formed of a leaf spring that contacts the side surface of the pinion 64 and urges the pinion 64 in the axial direction. 16, and as mentioned above, the pinion 64 is made freely movable in the axial direction. The switching means here are provided at both upper and lower ends of the rail 9, respectively. Arranged at the upper end of the rail 9
As shown in FIGS. 3 and 5, the id spring 15 presses and urges the pinion 64, which is in a position where it is not engaged with the rack 90, in the direction of engagement with the rack 90 as it moves upward. , when the teeth are aligned with the rack 90, the pinion 6
4 in the ring direction to the meshing position,
As shown in FIG. 4, the id spring 16 disposed at the lower end of the rail 9 moves the pinion 64 to a position where it does not engage with the rack 90 as it moves downward. In order to facilitate the control of the engagement with the rack 90 due to the movement of the pinion 64, the teeth of the upper and lower layers of the rack 90 are ground down to a height up to the reference pitch line, as is clear from the drawing. In addition, at the upper end of the rack 90, which is the side where the pinion 64 moves and engages, the teeth are crowned. Further, at the lower end of the rack 90, the teeth are not only lowered, but are also removed from the middle. There may be a positional deviation between the position of the id spring 16 and the toothless portion of the rack 90.

Furthermore, since the binion 64 is movable in the axial direction of the shaft 62, care is taken to prevent the binion 64 and the rack 90 from becoming disengaged during vertical movement.
A side plate 91 with a radius larger than the dedendum circle and smaller than the tip circle of the binion 64, that is, approximately equal to the pitch circle radius, is welded to one side of the binion 64, and when the two are engaged, the side plate 91 64 is in contact with the side plate 73, and the side plate 91
is located on the side of the rack 90, so that the binion 64
The gears are designed to prevent them from moving in the axial direction, or in other words, to prevent them from becoming disengaged. Also,
In the disengaged state, the binion 64 and rack 90
Since the side plate 91 is located in the open position, the pinion 64 will not move and hit the teeth of the rack 90.

Furthermore, backlash between the rack 90 and the pinion 64 will cause the movement of the treatment element 6 to wobble and cause physical harm if the load fluctuation is large, such as when the treatment element 6 is being rotated and moved up and down. In order to provide pleasure, twist the binion 64 and attach it to the rack 9 with the spring 79 as described above.
It is biased toward the 0 side to reduce backlash.

By the way, in this pine surge machine, the engagement between the binion 64 and the rack 90 is controlled by the switching means as described above, but the switching operation does not occur when the id springs 15 and 16 are installed. This is done only when the control circuit C gives a switching command in response to an input from the operation switch SW, etc., and normally only within the operating range shown in Figure 9, that is, at both ends of the 27790. By the time the binion 64 reaches the switching area where the id springs 15 and 16 are installed, the rotational direction of the motor 7 is controlled to be reversed, and the binion 64 and the rack 90 are maintained in an engaged state or a non-engaged state. It is now possible to do so. A position detection sensor 55 for detecting the vertical position of the treatment element 0 necessary for performing such control is stretched between pulleys 53 and 54 attached to the lower plate 20 and the upper plate 21. It is configured to optically detect a small hole bored in a belt 50 connected to a feed nut body 60 via a tensile spring 51. The small hole provided in the belt 50 is
The position at which the vertical movement direction of the treatment element 6 should be reversed, that is, the position at which it should be reversed ×1 without changing the engagement state between the binion 64 and the rack 90. ×2 and the position Xo* that should be reversed immediately after the meshing state changes
Xi, the treatment element 6 storage position x 2 at the lowest end of the rail 9, and the position where the treatment element 6 should be reversed during its vertical movement.

Next, a description will be given of the control circuit C that receives input from the operation switch and supports switching operations.

This control circuit C is formed by a one-chip microcomputer, and includes a timer circuit CT and a count circuit CC, an operation switch SW installed on the side of one of the seven cells, and the above-mentioned position detection circuit. A sensor 55, a power supply circuit, etc. are connected, and a motor drive circuit M
It is connected to the motor 7 via. Operation switch SW
In a state where no instruction to change the type of pine surge is received from
Each time the same position of x2 is reached, a command is given to the motor drive circuit M to reverse the rotational direction of the motor 7, thereby continuing the continuous pressing or rasping pine surge. When a command to change to continuous press pine surge is input from the operation switch SW, the control circuit C controls the upward movement of the treatment element 6 from the pinion 64.
The rotation is continued even when the pinion 64 is far from the x1 position, and the direction of rotation of the motor 7 is reversed only when the pinion 64 reaches the x0 position. At the same time, the timer circuit CT
is activated, and by this timer circuit CT output, the rotational direction of the motor 7 is reversed again until the pinion 64 exits the switching area, and furthermore, the pinion 64 is turned to X. When the position is reached, the counter circuit C
After repeating this several times while counting at C, the treatment element 6 is moved downward. The treatment element 6 repeatedly runs within a small range before moving from the rubbing pine surge to the continuous pushing pine surge. Similarly, during continuous press pine surge, press the operation switch SW to
When a command to change to surge is input, U・Nku 9
Within the switching region at the lower end of 0, the treatment element 6 repeatedly travels within a small range.

Continuous pressing from wasasuwa, or stroking from continuous pressing・＼
When the type of pine surge is switched, the switching is not done immediately, but the treatment element 6 repeatedly travels within a small range, so that the user will be able to switch the type of pine surge. It is possible to clearly recognize what is being done. Ma again
In this pine surge machine, the switching operation of the surge type is performed by the meshing of the binion 64 and the rack 90 as described above, and the above-mentioned repetitive running within the switching area is performed by the engagement between the binion 64 and the rack 90. This ensures control of the engagement with the rack 90. , that is,
If the pinion 64 and the rack 90 mesh even slightly, a force will be applied to the tooth surfaces to transmit torque, which will hinder the movement of the pinion 64 in the thrust direction, that is, the switching operation. Binion 64 and rack 9
0 and 0, the switching operation is reliably performed because the above-mentioned pressing is reversed multiple times, which is the time when no force is generated.

[Effects of the Invention] As described above, in the present invention, when switching the type of pine surge depending on the rotational movement and non-rotation movement of the treatment element, the treatment element can be used to repeatedly travel within a small range. By being clearly aware that a change in the type of pine surge is about to occur, a person can prepare for this and therefore be able to obtain a comfortable pine surge without causing muscle pain or surprise. In addition, when the clothes are stretched and tense due to being pulled by the treatment child, this will be released.
In this respect as well, a comfortable pine surge can be obtained.
