Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a pine-surge chair in which a pine-surge mechanism is incorporated in the backrest of a rocking-chair type chair that is capable of swinging.

[Background Art 1 There is a device in which a pine surge mechanism is incorporated into the backrest of a 0-tuking chair, as shown in Japanese Utility Model Application No. 57-142538, but the pine surge mechanism here is of a non-vibration type, and the massager Simply move the light up and down inside the backrest to illuminate the back of the human body and perform a massage. By the way, pine surge is more effective when its strength varies, and it is said that it is best to perform a very light pine surge, especially in the early and final stages of pine surge. However, with the method disclosed in the above publication, only a single pine surge operation could be performed, and therefore, effective pine surge could not be obtained.

[Objective of the Invention] The present invention has been made in view of the above points, and has the following objectives: 1. In addition to the non-vibration type pine surge operation of the pine surge fihN, the present invention can also provide mild stimulation by vibration. You can also get a pine serge chair on offer.

[Disclosure of the Invention] Accordingly, the present invention provides a pine surge chair in which a non-vibration type pine surge m structure is disposed on the backrest of the chair that can be swung. The gist is that the pine surge mechanism is provided with a motor for driving both the vibrator and the pine surge PIi structure, and a power transmission switching means for selectively transmitting the motor output to the pine surge mechanism and the vibrator. non-vibrating pine surge,
The feature is that a vibrating pine surge can be obtained using a vibrator.

The present invention will be described in detail below based on the illustrated embodiments.The chair herein includes a frame 1 in which a backrest portion and a seat portion are constructed as an integrally molded synthetic resin product having a recess on the front surface.
The back support bodies 2, 2 are attached to the front sides of the frame 1, the seat body 3 is attached to the upper surface of the seat, and the head support body 4 is attached to the upper end. There is. Each of these ukes are body 2
, 3.4 are composed of a plate-shaped core material 10 which is a synthetic resin molded product and is fixed to the 7-frame 1, and a cushion 11 made of foamed urethane resin or the like arranged on the surface of the core material 10. As shown in FIGS. 5 and 6 in the case of the body 2, the surface of the cushion 11 is further covered with a surface material 12 such as cloth or leather.
3.4 The entire body and both backrests are covered between the body 2.2 and the cover 5.
covered by. Here, both sides of the frame 1 and both back supports attached thereto are shaped into a substantially S-shape to conform to the shape of the back of the human body. The lower back is supported, allowing you to maintain a natural and comfortable posture.

In this chair, whose outer shell is shaped as described above, the bottom surface of the frame 1 itself serves as the ground surface.

In other words, the bottom of the frame 1, which is the back of the seat, is divided into three parts from its front end to the back of the joint between the backrest and the seat, with the front end facing towards the front end of the seat. An inclined surface 31 rising diagonally upward, a horizontal ground surface 32 in the middle,
The rear end portion is an arc-shaped ground plane 33 that rises in an arc backwards, and a stopper 14 that is slidable back and forth is attached to the arc-shaped ground plane 33. Move the stopper 14 forward, that is, towards the horizontal ground plane 32
If you move it to the side, you will no longer be able to rock the chair, and if you move the stopper 14 to the rear end of the arcuate ground plane 33, you will be able to rock the chair, in other words, you can use it as a rocking chair. At this time, the stopper 14 regulates the maximum angle at which the chair can be swung backwards to prevent it from falling backwards. The horizontal ground plane 32 is connected to the above-mentioned stop bar 14.
This will stabilize the chair in an upright position, and
When rocking as a rocking chair, the forward swing angle is restricted to prevent the body from floating off the backrest.

Now, inside the chair, there is a pine surge mechanism equipped with a treatment element 6 for performing acupressure and rubbing pine surgery, which are non-vibrating pine surges, an exciter 40 for vibrating pine surge, and a motor 7 for driving these. is stored. The motor 7 is connected to a lower plate 2 installed at the lower part of the frame 1.
0 and the upper plate 2 installed at the top inside the frame 1
It is suspended and attached to the lower plate 20 of 1 and 2 by vibration isolating rubber 70, and is located in the seat part, and the treatment element 6 is installed between the above two plates 20 and 21 via a bearing. It is provided on a movable block attached to the drive@8 as a hollow feed screw, and is located inside the backrest part. Both plays above) 20.21
In addition to the drive shaft 8, the opening includes a rotating ring 42 that passes through the inside of the drive shaft 8, a rail 9 located in front of the drive shaft 8, and a shape with a large section modulus that surrounds both sides and the rear of the drive shaft 8. A reinforcing frame 80 is constructed. Drive shaft 8 and rotating wheel 42
While both the reinforcing frame 80 and the reinforcing frame 80 are linear,
The rail 9 is bent forward at the upper part and rearward at the lower part, and the back support approaches the cover 5 at the waist and shoulders due to the relationship with the shape of the body 2.
It is separated from the cover 5 at the back part between this time. Moreover, this rail 9 has a double-shaped cross section that opens only at the rear, and has a rack 90 on its inner surface.
is fixed.

The movable block to which the treatment element 6 in the Pine Surge W1m is attached is rotated by the rotation of the drive shaft 8 whose lower end is connected to the motor 7 by a belt 71 and a clutch 72.
While moving up and down along the rail 9, the rack 90
The treatment element 6 is rotationally driven by engagement with the feed nut body 60, which is threadedly engaged with the drive shaft 8, which is a feed screw. It consists of a pair of arms 61, 61 whose one end is pivotally supported by the feed nut body 60, a shaft 62 held at the other end of both arms 61, 61, etc., and the treatment element 6 is mounted on both sides of the rail 9. A pair of rotating plates 65 and 65 are welded and fixed to the shaft 62, and a roller 66 is freely rotatably attached to each tip of the radial projection of both rotating plates 65 via a shaft 67 and a roller bearing 68. It is configured.

To explain the movable block in more detail, the feed nut body 60 further surrounds the outer surface of a reinforcing frame 80 that has a U-shaped cross section and surrounds the drive shaft 8 to which it is screwed. It is provided with a sliding portion and an idler roller 83 that moves on the rear back surface of the reinforcing frame 80. The shaft 62 is provided with a spline 63 or a key at its center, and a pinion 64 is attached to the shaft 62 so as to be slidable in the axial direction and rotate integrally with the shaft 62. Guide disks 13, 13 are freely rotatable, and guide rollers 74, 74 are attached to both sides of the disks via bearings 75, and guide rollers 76, 76 are attached to both ends of the shaft 62. There is. The above-mentioned pinion 64 meshes with the rack 90 fixed to the rail 9, and the idle roller 74 and 74 roll on the front surface of the rail 9 to support the load applied to the treatment element 6. 78 is supported by a shaft 77 passed between its tips. Also, this is the ID plate 74.
The other end of a torsion coil spring 79, which is attached to the outer periphery of the shaft 62 and has one end locked to the arm 61, is locked to 74. The torsion fill spring 79 biases the feed nut body 60 in a direction to press the shaft 62 toward the rail 9 side. The above-mentioned double-sided disks 73° 73 are located along the opposing inner surfaces of both sides of the rail 9, and by bringing the outer peripheral edge into contact with the rail 9,
This prevents interference in meshing between the binion 64 and the rack 90, and also prevents interference between the rack 90 and the binion 6, which will be described later.
When the engagement with 4 is released, the torsion coil spring 7
9 prevents the pinion 64 from coming into contact with the bottom surface of the rail 9. Guide rollers 76 at both ends of the shaft 62
76 is located at a distance in front of the rail surface 19 formed on the frame 1, and although it does not normally come into contact with this rail surface 19, it is possible that abnormal shellfish may be added to the treatment element 6. When the treatment element 6 tries to move backward, the rail surface 1
9, the idle roller 78 and the pinion 64
This prevents the rail 9 sandwiched between the idle disk 73 and the rail 9 from being deformed.

Next is the treatment element 6, which, as mentioned above, is made up of the rotating plates 65 and 65 of the lamp, and the tips of the radial protrusions on both rotating plates 65, which are freely rotated through the shaft 67 and roller bearings 68. 4 to 6 rollers 66 (in the illustrated example, 5 rollers 66 are provided at equal intervals on the outer periphery of one rotating plate 65) are freely attached rollers 66. Further, the roller 66 is a blow-molded product of synthetic resin or a soft material made of rubber or the like.

The vibrator 40 for vibration pine surge has an eccentric weight attached to the upper end of a rotating wheel 42 that is fitted into the drive shaft 8 and supported by bearings 85, 85 arranged on the inner surface of both ends of the drive shaft 8. 41, and is installed above the upper plate 21, that is, in the upper part of the backrest part. The lower end of the rotating wheel 42 is connected to the motor via a clutch 43 and a belt 71.

The power transmission switching means having the clutch 72 and the clutch 43 as main components will be explained. As shown in FIG. 2, boobies 17-48 and 49 are rotatably attached to the lower end of the drive shaft 8 and the lower end of the rotary wheel 42, respectively, and between each pulley 48, 49 and the motor 7. The belt 71 is hooked up. Both clutches 43, 72 are each composed of a clutch core 91, a fill 92, and a first yoke 93. The clutch 43 has its clutch core 91 fixed to the rotating wheel 42, and the clutch 72 has its clutch core 91 fixed to the rotary wheel 42. It is fixed to the drive shaft 8. and pulley 4
8 has a clutch spring 47 on the surface on the clutch 72 side.
A clutch shoe 46 is attached to the surface of the pulley 49 on the clutch 43 side via a clutch spring 45, and a clutch shoe 44 is attached to the surface of the pulley 49 on the clutch 43 side. Both of these clutch shoes 46 and 44 are Boo I7-48,
At the same time, the clutch spring 47.4 rotates together with the clutch spring 47.4.
5, each can be moved slightly in the thrust direction.

In this Pine Surge chair configured as described above, if the coil 92 of the clutch 43 is energized and the motor 7 is rotated with the clutch shoe 44 attracted to the clutch core 91 as shown in FIG. The rotation of the motor 7 is transmitted to the rotating ring 42, and rotates the eccentric weight 41 attached to the other end of the rotating ring 42. As a result, vibrations are applied to the backrest assembly, and a vibrating surge can be obtained. In particular, an exciter 40 is installed at the upper end of the 7 frame 1 whose lower end serves as a ground plane that enables rocking.
Because the chair is installed in the chair, it is possible to obtain vibrations with a large amplitude, and the chair also rocks along with the vibrations, creating a gentle rocking effect. The user can feel relaxed without having to swing the chair.

Next, when the coil 92 of the clutch 72 is energized and the motor 7 is rotated with the clutch shoe 46 attracted to the clutch core 91 as shown in FIG. The movable block to which the feed nut body 60 is screwed onto the drive shaft 8 moves up and down as the drive shaft 8 rotates. At this time, the treatment element 〇 also moves up and down, but the torsion coil spring 7
The pinion 64 is biased to mesh with the rack 90 by the id roller 78 and the id disk 73 so as to maintain a pitch distance, and the pinion 64 slides in the axial direction with respect to the shaft 62. So, tJS
As shown in Figure 5, the state in which it is engaged with the rack 90 and
As shown in the figure, there are two states: a state in which the movable block is not engaged, and a state in which the pinion 64 is not engaged. The child 6 is rotated around the shaft 62. In the latter case, since the treatment element 6 is separated from the rack 90, it is in a free state,
As a result, the treatment element 6 only moves up and down with the two rollers 66 in a stable state in contact with the inner surface of the cover 5.

When the treatment element 6 is rotated and moved up and down, each roller 66 located on the outer periphery of the rotating plate 65 sequentially presses the back of the human body via the cover 5. At this time, two rollers 66 are in contact with the back of the human body, and one roller 66 is in contact with the back of the human body.
Since the distance of the roller 66 from the rail 9 at the time of contact with the human body is different in the two states, the difference in the two distances can be suppressed by acupressure. It is applied to the human body, and this pine surge is applied along the back muscles of the human body. When the treatment element 6 is moved up and down without rotating, the two adjacent rollers 66 rub the back of the human body. 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.
If only the cover 5 is interposed in the opening, it will cause pain, so a cushion part 58 is provided on the back side of the center part in the width direction of the cover 5.

The engagement between the rack 90 and the pinion 64 is controlled by switching members (
(not shown) presses the pinion 64 in the sleeve direction to change the axial position of the pinion 64.

Further, such a switching operation is performed only when a switching command is given by an operation switch, etc., and normally the rotational direction of the motor 7 is changed by the time the pinion 64 reaches the part where the switching member is installed. is controlled in reverse, and the binion 6
4 and the rack 90 are maintained in an engaged state or in a non-engaged state. A position detection mechanism for detecting the vertical position of the treatment element 6 necessary for performing such control includes a boot 953 attached to the lower plate 20 and the upper plate 21.
a bell) 50 which is stretched across 54 and connected to a feed nut body 60 via a tension spring 51;
The detection unit 55 optically detects the small hole drilled in the bell) 50.

Furthermore, in this embodiment, not only can non-vibrating pine surge and vibrating pine surge be selectively performed depending on which of the clutches 72 or 43 is connected, but also the clutch 72 or 43 can be selectively operated in response to each pine surge. 72 and 43, both clutches 72 and 43 are provided, as shown in FIG.
．． By connecting 43 at the same time, it is possible to obtain both vibrating pine surge and non-vibrating pine surge at the same time.

[Effects of the Invention] As described above, in the present invention, in addition to the non-vibrating pine surge produced by the pine surge mechanism, it is possible to obtain the vibrating pine surge produced by the vibrator.
In particular, the vibration pine surge using a vibrator not only applies vibrations to the human body, but also applies a shaking effect to the entire chair that can be rocked, so it creates a more relaxing feeling. At the same time, since the vibrator is installed at the top of the backrest, it is possible to generate large vibrations. Furthermore, different lI
In addition to being able to obtain H pine surgery, there is a wide range of treatments available, and it is an effective treatment that involves relaxing the body with mild pine surgery, followed by strong pine surgery, and finally, another mild pine surgery to calm the body. Although it is possible to take different courses and to obtain different types of pine surges, since it is equipped with a power transmission switching means, only one motor is used as the power source.
It is a good thing.
