Description

[Detailed Description of the Invention] (Technical Field of the Invention) This invention relates to a pine surgery device that can perform pine surgery on a user's entire body.

(Technical background of the invention and its problems) Generally, a pine surge device has a pair of guide rails laid along the longitudinal direction on the top surface of the base.
A holder to which a pine surge roller is attached is provided so as to be freely movable along this guide rail. Further, a drive device is provided at one end in the longitudinal direction of the base, and the pine surge roller is driven to travel by this drive device.

By the way, in the pine surgery device having such a structure, in order to enable the pine surgery roller to perform pine surgery on the user's entire body, the base body must be made longer than the user's height. For this reason, the pine surge device is quite large, which is very intrusive when not in use, and
When storing it, it was difficult to secure a storage space, and it was also inconvenient to carry.

Therefore, in order to eliminate such drawbacks, the applicant of the present invention proposed a pine surge device disclosed in Japanese Patent Application No. 185132/1985 (unpublished). That is, in this pine surge device, the base body and the guide rail can be bent, and the length dimension can be reduced by folding the base body and the guide rail when not in use. However, in such a pine surge device, when the base body and the guide rail are bent, if the holder is located at the bending part, the base body and the guide rail cannot be bent by the holder. The problem is that it disappears.

(Purpose of the invention) This invention was made based on the above-mentioned circumstances, and its purpose is that when the pine surge device is bent, even if the holder is located at the bent part, the holder To provide a pine surge device which is prevented from being unable to be folded and bent and whose thickness is not increased.

(Example of the invention) An example of this invention is shown below in Figures 1 to 16.
This will be explained with reference to the figures. The pine surge device 1 shown in FIG. 1 includes a base 2 in the shape of a rectangular plate. As shown in FIG. 9, this base body 2 includes a rectangular first plate-like body 3 and a second plate-like body bonded and fixed to the lower surface of the first plate-like body 3 except for the approximately central portion in the longitudinal direction. A pair of auxiliary members 5 each having an inclined surface are provided on the upper surface of the first plate-shaped member 3, located on the opposite side of the body 4 and a drive device 56, which will be described later, as shown in FIG. ing.

The first plate member 3 is made of a synthetic resin such as nylon, polypropylene, polyvinyl chloride, or urethane, which is relatively flexible and is not easily compressed under load. This first plate-like body 3 is provided with a large number of cavities 6 having a rectangular cross section that penetrate in the width direction thereof and are provided at regular intervals along the longitudinal direction, and a cavity 6 located approximately at the center in the longitudinal direction. One end of the slit 7 is open to the lower surface of the first plate member 3, and the other end thereof communicates with the slit 7. This slit 7
is provided over the entire length of the first plate-shaped body 3 in the width direction. Therefore, the first plate-shaped body 3 can be easily bent at its substantially central portion in the longitudinal direction by the cavity 6 and the slit 7, as shown in FIG. That is, the substantially central portion in the longitudinal direction of the first plate-like body 3 serves as a first flexible portion 8 that allows the first plate-like body 3 to be bent in two. The second plate-like body 4 is made of a material that is difficult to compress under load, such as synthetic resin or laminated plywood.

A pair of holding members 10 are provided on the upper surface of the base body 2 having such a structure so as to be spaced apart from each other in parallel along the longitudinal direction of the base body 2 . The holding member 10 is made of the same synthetic resin as the base body 2 and has a cross-sectional shape shown in FIG. 3. That is, the holding member 1
0 includes a band-shaped base 12, a substantially L-shaped locking part 14 provided at one end of the base 12 in the width direction, a band-shaped support part 16 provided at the other end, and the base 1
A pair of L-shaped pieces 18 are integrally formed, each protruding from one end side of 2 and the upper and lower surfaces of the middle part in the width direction. Each pair of L-shaped pieces 18 defines an upper passage 20 on the upper surface side of the base 12, and a lower passage 22 on the lower surface side.

Only one longitudinal end of the holding member 10 is fixed with a screw 26 of the base body 2, as shown in FIG.
The other parts are slidably held by supports 28 shown in FIGS. 1 and 3.

This support 28 is attached to the base 2 by a screw (not shown).
The first holding part 34 is slidably engaged with the locking part 14, and the second holding part 36 is slidably engaged with the supporting part 16. Therefore, the other end of the holding member 10 is expandable and retractable with respect to the base body 2.
Further, as shown in FIGS. 10 and 11, a locking portion 14 of the holding member 10 is located at a portion of the holding member 10 corresponding to the first flexible portion 8 of the base body 2, that is, approximately at the center in the longitudinal direction. A large number of slits 38 are formed over the entire length of the support portion 16 and the L-shaped piece 18 in the width direction and at regular intervals in the longitudinal direction. Therefore, the substantially central portion in the longitudinal direction of the holding member 10 becomes a second flexible portion 40 that can be bent together with the first flexible portion 8 by the slit 38, as shown in FIG. ing.

On the other hand, the other end of the holding member 10 is bent upward away from the upper surface of the base 2, and the holding member 10 is bent upwardly on the lower surface of this portion as shown in FIGS. 5 and 6. A pedestal 42 is attached to hold it. A pitching roll 44 is rotatably supported by a support shaft 46 in the middle of this pedestal 42.
A support pulley 48 is rotatably supported by a support shaft 50 at an end protruding from the other end of the holding member 10 . Furthermore, the holding member 10 and the pedestal 42
An opening 52 is formed at a location corresponding to the pitching roll 44.

A drive device 5 is provided on the upper surface of one end in the longitudinal direction of the base body 2.
6 is provided. This drive device 56 has a case 58 fixed to the base body 2. As shown in FIG. 5, this case 58 is provided with a mounting plate 62 whose width is shorter than that of the case 58 and whose both ends are bent into substantially L-shaped support pieces 60.
A drive source 64 in which a speed reducer and a motor are integrated is attached to the mounting plate 62. This driving source 6
The four output shafts 66 protrude toward the outer surface of one of the support pieces 60. A first gear 68 is attached to this output shaft 66.
and the first drive pulley 70 are fitted.
Further, the mounting plate 62 is provided with a first mounting shaft 72 whose both ends are rotatably supported by the support piece 60. Both ends of this mounting shaft 72 are supported by support pieces 60.
The second gear 7 protrudes from the outer surface of the
4, and a second driving pulley 76 that forms a pair with the first driving pulley 70 are fitted. The second gear 74 meshes with the first gear 68. A third gear 78 and a third driving pulley 80 are fitted to the other end of the first mounting shaft 72 . In addition, the mounting plate 62 and the other support piece 6
0 is rotatably provided with a second mounting shaft 81. This second mounting shaft 81 has a fourth gear 82 that meshes with the third gear 78, and a fourth driving pulley 8 that is paired with the third driving pulley 80.
4 is fitted. Therefore, when the output shaft 66 is rotationally driven, the first gear 68 and the second gear
The gear 74 rotates in the opposite direction, and the third gear 78 and the fourth gear 82 rotate in the opposite direction. Note that the first to fourth gears rotate at the same number of rotations.

The first drive pulley 70 and the fourth drive pulley 84 are connected to each other as a power transmission strip 86, for example, a wire, a chain, or a belt formed of a steel plate, a stainless steel plate, cloth, or the like. In this case, one end portion of a pair of belts 86 is wound with the ends thereof being fixed to each other. This belt 86
is passed from the first and fourth drive pulleys 70, 84 to the upper passage of the support member 10, as shown in FIG. The midway portion led out from the upper passage 20 is hung on a support pulley 48 provided on the pedestal 42.

The running direction of the belt 86 is changed approximately 180 degrees by the support pulley 48, and then the belt 86 passes through the opening 52 formed in the holding member 10 to the lower passage 22.
It is passed through. At the location of the opening 52, the running direction of the belt 86 is slightly changed by the pitching roll 44. The other end of the belt 86 led out from the lower passage 22 is wound around the second driving pulley 76 and the third driving pulley 80, respectively.

Therefore, when the first driving pulley 70 and the second driving pulley 76 or the third driving pulley 80 and the fourth driving pulley 84, which are paired with each other, are rotated in opposite directions, the belt is rotated. 86 is wound up on one driving pulley and sent out from the other pulley by the wound length. For example, in FIG.
is in the direction of arrow X, and the second drive pulley 76 is in the direction of arrow Y.
When rotated in the direction, the portion of the belt 86 inserted into the upper passage 20 runs in the direction of arrow Z.

A pair of holders 90 are provided between the pair of holding members 10, as shown in FIG. 1, and spaced apart at a predetermined interval along the longitudinal direction of the holding member 10.
This holder 90 has a hollow shaft 92 as shown in FIG.
It is equipped with A boss portion 9 is formed at one end of a pair of first links 93 at both ends of the hollow shaft 92.
4 is rotatably fitted on the outside. In addition, the hollow shaft 9
2 has a screw shaft 98 inserted therethrough. Both ends of this screw shaft 98 on which male threads 100 are formed protrude from a wall portion 102 formed on the boss portion 94 of one first link 93, and a female thread 104 is screwed into the male thread 100. . In other words, the screw shaft 9
8 holds the boss portions 94 of the pair of first links 93 so that they do not come out from the hollow shaft 92.

At the other end of the first link 93, a wheel 108 is attached to a support shaft 10, as shown in FIGS. 12 to 14.
9, it is rotatably provided. Further, one end of a second link 111 is rotatably connected to the support shaft 109, and the first connecting member 1
12 is attached.

The other end of the pair of second links 111 is a support shaft 113
A second connecting member 114 is attached to the support shaft 113. The first and second connecting members 11
2, 114 has a substantially inverted T-shaped cross section, one vertical side of which is attached to each support shaft 109, 113, and the other horizontal side inserted into the upper passage 20 of the holding member 10 and connected to the belt 86. For example, it is fixed by welding. A pair of first connecting members 112
is fixed to the belt 86 at an interval such that the pair of second links 111 are substantially in a straight line;
This pair of second links 111 and the pair of first links 111
The link 93 forms a substantially triangular shape. Further, a tongue piece 11 is provided at the other end of the second link 111.
5 is formed, and this tongue piece 115 comes into contact with the side surface of the second connecting member 114 when the pair of second links 111 are substantially in a straight line, so that the second link 111 uses the support shaft 113 as a fulcrum. Prevents further downward rotation.

Note that a long hole 117 is formed in one side of the first connecting member 112, and the support shaft 109 is inserted through this long hole 117.

Furthermore, the hollow shaft 92 has four collars 116.
is provided in such a manner that it is rotatable and does not shift in the axial direction. A pine surge roller 118 is attached to each collar 116. This pine surge roller 118 is molded from a relatively hard elastic material such as rubber or synthetic resin, and has a large number of substantially hemispherical protrusions 120 protruding from its outer peripheral surface at predetermined intervals in the circumferential direction. . A stopper 122 is provided on the outer peripheral surface of each collar 116 to prevent the pine surge roller 118 from shifting in the axial direction of the collar 116.

On the other hand, on the upper surface of the base 2, a wall member 160 is provided on the outside of the pair of holding members 10 and at one longitudinal end of the base 2, as shown in FIG. The wall member 160 is made of a bendable elastic material, such as urethane foam. Further, the base body 2 is covered with an exterior material 162 made of a cloth having relatively excellent abrasion resistance, such as canvas or nylon cloth, sewn into a bag shape.

Note that the driving device 56 is controlled by a mechanical or electrical control device (not shown), so that the running direction of the belt 86 can be changed. Further, the drive device 56 can be remotely operated by a switch box (not shown).

Next, a case where the pine surgery device 1 having the above structure is used will be explained. First, when the user lies face up on the pine surgery device 1, the user operates a switch box (not shown) to activate the drive source 64 of the drive device 56. When this drive source 64 operates and the output shaft 66 rotates in the clockwise direction indicated by arrow X in FIG. 6, the first drive pulley 70 and the fourth drive pulley 84 rotate in the same direction, and The second driving pulley 76 and the third driving pulley 80 rotate in opposite directions. Therefore, the pair of belts 86 are wound around the first driving pulley 70 and the fourth driving pulley 84, respectively, and depending on the winding, the pair of belts 86 are wound around the second driving pulley 76 and the third driving pulley 84, respectively. Since the belt 86 is fed out from the pulley 80, the portion of the belt 86 inserted into the upper passage 20 of the holding member 10 runs in the direction shown by arrow Z in FIG. When this belt 86 runs, a pair of holders 90 are interlocked via first and second connecting members 112 and 114 fixed to this belt 86. A plurality of pine surge rollers 118 travel while rotating in the direction shown by arrow S in FIG. 12 due to contact with the inner surface of the exterior fabric 102, and their protrusions 120 pine surge the user's back. And the above pine surge roller 11
When belt 8 reaches a predetermined position, a control device (not shown) causes the portion of belt 86 inserted through upper passage 20 to travel in a direction opposite to the direction of arrow Z shown in FIG.

Therefore, since the pair of holders 90 are interlocked with the running of the belt 86, the pair of holders 90 are reciprocated along the longitudinal direction of the base, and the user is massaged by the massage roller 118.

By the way, when the pine surge device 1 is not in use, it can be folded into two from approximately the center in the longitudinal direction of the base body 2, as shown in FIG. That is, since the substantially central portions in the longitudinal direction of the base body 2 and the holding member 10 are formed into the bendable first flexible portion 8 and the second flexible portion 40, respectively,
The base body 2 and the holding member 10 can be folded into two together with a wall member 160 provided on the upper surface of the base body 2. Therefore, the length of the pine surge device 1 can be reduced to about half when not in use, making it convenient for storage and transportation. In this way, when folding the pine surge device 1, the base 2
The holder 90 may be stopped on the first and second flexible parts 8 and 40, which are the bent portions of the holder 10 and the holder 10. When the base body 2 and the holding member 10 are bent in this state, the pair of first connecting members 112 are pressed by the holding member 10.
As shown by arrows in FIG. 16, the pair of second links 111 rotate about the support shaft 113, and in conjunction with this rotation, the pair of first links 93 rotate around the hollow shaft 113.
2 as a fulcrum and rotates in the direction where the angle formed by these becomes smaller. In other words, the first and second links 9
3, 111 deforms from a triangular shape to a quadrangular shape as the base body 2 and the holding member 10 are bent.
It can be folded without any restrictions.
Further, when the base body 2 and the holding member 10 are unfolded from the folded state, a pair of first connecting members 112
is pulled by the holding member 10, and the first and second links 93, 111 rotate in the opposite direction, so that the shape of the first and second links 93, 111 changes from a quadrangle to a three-dimensional shape. Return to square shape. In other words, the first and second connecting members 112 and 114 connect the holder 90 to the belt 8 when using the pine surge device 1.
6, and when folded when not in use, the connection shape of the first and second links 93, 111 is deformed to enable the base body 2 and the holding member 10 to be bent.

Further, the base body 2 is made of a plate-shaped body, and this base body 2
The driving device 56, the holding member 10, and the wall member 1 are on the top surface of the
60 etc., it is possible to reduce the thickness of the pine surge device. Therefore, since the thickness does not increase even when folded, it is convenient for storage and transportation. Furthermore, the base 2
A wall member 16 made of an elastic material provided on the upper surface of the
0 supports the user flexibly to a certain extent, so compared to a device in which the user is supported only by the pine surge roller, the whole weight is not applied to the pine surge roller, so good pine surge can be obtained.

Note that this invention is not limited to the above-mentioned example,
The number and position of the first and second flexible parts formed on the base body and the holding member may be changed.

For example, by forming two first and second flexible parts each in the middle of the base body and the holding member in the longitudinal direction, the pine surge device can be folded into three parts. Further, the base body 2 and the holding member 10 are provided with first and second
They may also be made of a bendable material, such as nylon, without forming any flexible portions. Furthermore, although a belt is shown as the power transmission strip in this embodiment, it does not necessarily have to be a belt, and may be a wire or chain.

(Effects of the invention) As described above, this invention includes a base made of a plate-shaped body having a flexible part that can be bent, a wall member made of an elastic material on the upper surface of this base, and a pine surge roller attached. a pair of first links each having one end rotatably connected to both ends of the shaft and a wheel connected to the base body at the other end; one end pivotally connected to the other end of these first links; and a pair of second links whose other ends are rotatably connected to each other, and the second links run along a bendable holding member at one end and the other end. It was connected to the belt with a connecting member.

Therefore, the holding body is interlocked with the running of the power transmission strip through the connecting member, and even if the holding body is located at the bent portion when the base body and the holding member are bent, the first, Since the connecting shape of the second link deforms according to the bending state of the holding member, the base body and the holding member can be bent without being restricted by the holding member.

Furthermore, since the thickness of the pine surge device can be reduced, it does not become thick even when folded when not in use, making it convenient for storage and transportation.
In addition, since the wall members support the user to some extent,
A good pine surge can be performed without the user's entire weight being applied to the pine surge roller.
