DETAILED DESCRIPTION OF THE INVENTION Technical Field 1 The present invention relates to a pine surgery chair in which a treatment member for pine surgery is housed within the backrest of the chair.

[Background Art] In a pine surgery chair in which a treatment member for pine surgery is arranged in the backrest, after storing the treatment member and the driving member for driving the treatment member in the casing,
However, in conventional Matusage chairs, the backrest and seat, which support the body, are formed separately and attached to the casing individually. Since there are many parts, assembly and disassembly work is very time-consuming, which makes after-sales service particularly difficult.

[Object of the Invention J] The present invention has been made in view of the above points, and its object is to provide a pine-surge chair that can be easily assembled and disassembled.

[Disclosure 1 of the Invention] The present invention provides a bottomed casing that is open on one side and houses a treatment member and a driving member for the treatment member, and a backrest surface and a seat surface that are integrally provided. The backrest surface and the seat surface are integrally formed as a cover that closes the opening surface of the bottomed casing, so that it can be assembled by simply attaching and detaching the cover to the casing. and disassembly.

The present invention will be described in detail below based on the illustrated embodiment.The outer shell of this Matusage chair is made of synthetic resin so that the side surface shape is an abbreviated letter shape, and the front side is open and has a bottomed box shape. It consists of a casing 1 formed by molding, and a cover 2 that covers the front opening of the casing 1. As will be described later, a treatment element 6 and a drive member for moving the treatment element 6 up and down are housed in four places on the front surface of the casing 1, and these treatment elements 6 and The drive member is covered, but the cover 2 here covers the pair of back supports arranged on both sides of the front of the casing 1, the seat supports forming the seat surface, and the head support. The four receivers are equipped with parts, and each of these parts is made of a plate-shaped core material 10 as a synthetic resin molded product, and foamed urethane resin etc. arranged on the surface of the core material 10. Cushion 11
and a surface material 5 stretched on the surface, and a plate-shaped core material 10 in each receiver part is formed as an integrally molded product. In other words, the cover 2 is the plate-like core material 1
After attaching the cover plate 11 to the key points of the headrest, by applying the surface material 5 over the entire surface, the headrest, which is a headrest, is formed into a head rest part, a back rest part, and a seat support part. As shown in FIG. 6, the plate-shaped core material 10 is screwed into a screw-fastening portion 55 formed at the edge of the opening of the casing 1. By being fixed, the cover 2 is fixed to the casing 1.

Inside a casing 1 whose front opening is closed by a cover 2, a treatment element 6 for pine surgery and a motor 7 for driving the treatment element 6 are housed. The motor 7 is suspended and attached to a 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 7 frame 1 by a vibration isolating rubber 70. The treatment element 6 is attached to a drive shaft 8 as a feed screw installed between the two plates 20 and 21 via a bearing. It is provided on the movable block and 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 surrounding both sides and rear of the drive shaft 8 are installed between the above-mentioned play shafts 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. The rail 9 has a U-shaped cross section that opens only toward the rear, and has a rack 90 fixed to its inner surface.

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.
The feed nut body 60 is rotatably driven by meshing with the feed nut body 60, which is hinged to the drive shaft 8 which is a feed screw. a pair of arms 61, one end of which 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 shaft 67 and a single roller bearing 68.
It is composed of.

As shown in FIG. 4, 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 an idle roller 83 that rolls on the rear surface of the reinforcing frame 80. The shaft 62 is provided with a spline 63 or a key in its center,
The pinion 64 is slidable in the axial direction and the shaft 6
2, and on both sides of this spline 63 there are id disks 73.7.
3 can freely rotate, and there are guide plays on both sides of this)
74, 74 are attached via a bearing 75.

The above-mentioned pinion 64 meshes with a rack 90 fixed to the rail 9, and is attached to both sides (id brake) 74.
An idle roller 78, which rolls on the front surface of the rail 9 and supports the load applied to the treatment element 6, is supported by a sleeve 77 passed between its tips. Also this
The other end of a torsion fill 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 the idle plate 74,74. The torsion coil spring 79 urges the feed nut body 60 in a direction to press the shaft 62 against the rail 991m.

Both γ-id disks 73 located on both sides of the binion 64.
73 is 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,
The meshing pitch between the pinion 64 and the rack 90 is determined to prevent interference between the two meshes, and when the rack 90 and pinion 64 are disengaged, which will be described later, the torsion coil spring 79 is applied. This prevents the pinion 64 from coming into contact with the bottom surface of the rail 9 due to force.

Next is the treatment element 6, which, as mentioned above, consists of a pair of roller plates 65, 65 and both roller plates 65.
A roller 66 is attached to each tip of the radial protrusion through a roller bearing 67 and a roller bearing 68 so as to be rotatable.
Four to six rollers 66 are provided at equal intervals on the outer circumference of one roller plate 65.

In this Matusano machine configured as 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.
The pinion 64, which is guided by the guide disk 73 so as to maintain the pitch distance, slides in the axial direction with respect to the shaft 62, and has two states: one in which it is engaged with the rack 90, and the other in which it is not engaged. In the former case, the pinion 64 rotates due to engagement with the rack 90 as the movable block moves up and down, and the treatment element 6 is rotated around the shaft 62 via the shaft 62. . For this purpose, each roller 66 located on the outer periphery of the roller plate 65 presses the back of the human body through the cover 5 in sequence, and at this time, the two rollers 66
A state in which the roller 66 is in contact with the back of the human body and a state 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 Since the distances are different, acupressure pressure is applied to the human body at a difference in distance between the two, and this pine surge is applied along the back muscles of the back of the human body, and pine surge is a ``continuous press''. This is the result. In the latter case, the treatment element 6 is separated from the rack 90 and becomes free, and as a result, the treatment element 6 moves up and down with the two rollers 66 in a stable state in contact with the inner surface of the cover 5. Rolling is performed because the two rollers 66 that are in contact with the human body through the cover 5 move while rotating freely. 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. 27217 portion 58 is provided on the back side of the central portion of the cover 5 in the width direction. *A control member that controls the engagement with the rack 90 by moving the pinion 64 in the axial direction of the shaft 62 is installed at the upper and lower ends of the rail 9, but this control member will not be explained here. Omitted.

Now, the bottom of the casing 1 here is a ground plane that directly contacts the floor surface, and this ground plane draws a smooth arc from front to back.
The chair can be rocked back and forth. It is now a rocking chair. A stopper 13 is protruded from the rear end of this ground plane to prevent the chair from falling backwards, and the stopper 13 can be freely moved in and out of the front position and is biased by a spring in the protruding direction. A stopper 14 is attached. When the stopper 7 bar 14 is protruding, the chair does not fall backwards (although the user is in a stable posture, the user sits on the seat and leans against the backrest, causing the chair to fall slightly backwards). If you do,
Since the stopper 14 sinks into the casing 1 against the bias of the spring, it is in a so-called locking state. Further, on the back side of the casing 1, a recessed storage part 41 for storing a power cord 40 is formed, which can be opened and closed.

Furthermore, a pair of parallel ribs 4.4 are integrally provided on the bottom of the inner surface of the casing 1, which are located on both sides of the motor. These ribs 4, 4 to which the lower plate 20 is fixed have a box-shaped cross section that forms a groove on the lower surface of the casing 1, as is clear from the cross section shown in FIG. In addition to improving the strength of the casing 1, the upper surface of the casing 1 receives the inner surface of the seat portion of the cover 2, thereby reinforcing the strength of the cover 2 against the human body load. Also, a ventilation hole 46 is provided on the side of the motor 2@l of this rib 4.
is opened to allow heat from the motor 7, which does not have a fan for forced cooling, to escape to the outside. In terms of cooling the motor 7, ventilation holes 47, 48 are provided at the front end of the casing 1 and at the upper rear end.

Cooling air enters the casing 1 through the ventilation hole 47 at the front end, cools the motor 7 by passing between the two pumps 4, and is then discharged through the ventilation hole 48 at the upper rear end. It is. In addition, a control circuit block 50 for controlling the operation of the motor 7, etc. is disposed outside the rib 4, as shown in FIG. 5, in order to eliminate the influence of heat discharged from the motor 7. There is.

In the embodiments described above, a cover is shown in which the headrest is integrated with the backrest surface and the seat surface, but it goes without saying that the cover may have no headrest.
