  Conventionally, in a liquid tank in which liquid is stored, a movable carriage is provided so as to be movable along the direction of one side of the liquid tank, and then a jet liquid is ejected from an ejection section provided on the movable carriage toward the opening. There is a hydraulic massage device that massages a treatment site of a massage recipient who has entered a flexible sheet covering a liquid tank opening in a sitting posture with a jet liquid (see, for example, Patent Document 1).

JP2003-052782 JP-A-2005-261824

  During massage treatment using a hydraulic massage device, a massage recipient may perform an operation of lifting the lower limb from the floor or the seat to change the body orientation when getting on and off the seat. At the time of this operation, the entire weight may be applied to a part of the flexible sheet only through the collar portion, and the flexible sheet may be bent excessively. If such excessive sheet deflection occurs, it is considered that the massage recipient loses balance and falls. In order to prevent such excessive bending of the flexible sheet, it is conceivable to slightly weaken the flexibility of the flexible sheet or slightly increase the rigidity. However, when such a change is added, the flexible sheet is difficult to be deformed, and the massage effect by the jetting liquid jet is weakened. Therefore, this measure is not effective.

  In addition, Patent Document 2 includes an auxiliary support net or sheet fixed to the water tank so as to be spanned in the width direction of the liquid tank below the flexible waterproof sheet in the middle portion in the long side direction of the liquid tank. A hydraulic massage device is disclosed. According to this configuration, even if the flexible sheet covering the opening of the liquid tub is thin, the massage recipient can stably get on and off the flexible sheet.

Also, a natural rubber is adopted as a material of the flexible sheet of the hydraulic massage device, and a flexible sheet in which a special rubber layer is processed and formed on one surface of the natural rubber layer (a surface on which a massage recipient gets on and off) is formed. It is commercially available. However, when an auxiliary support net or the like is placed under the flexible sheet in the width direction of the liquid tank, the natural rubber layer and the auxiliary support net or the like are rubbed gradually due to repeated operations such as getting on and off the massage recipient. There was a problem that the natural rubber layer was worn.

  Therefore, the present invention has been made in view of the above-described problems, and suppresses excessive bending of the flexible sheet and prevents wear of the flexible sheet without causing any trouble in the massage effect. The main purpose is to provide a hydraulic massage device that can be used.

  The present invention includes a liquid tank having an opening on the upper surface and storing a liquid, a movable carriage provided in the liquid tank so as to be movable along one side of the liquid tank, and the movable carriage. An injection part that injects an injection liquid toward the opening, an injection liquid supply part that supplies the injection liquid to the injection part, and a massage recipient that is provided in the liquid tank so as to cover the opening. A flexible sheet that can be brought into contact with the upper surface of the sheet and can be carried on a seat, and a flexible reinforcing band, and the flexible reinforcing band is on the upper side of the flexible sheet, and the liquid tank It extends between the opening both ends of the said liquid tank along the direction which cross | intersects one side direction.

  A massage recipient may perform an action of lifting the lower limbs from the floor or the sheet to change the direction of the body when getting on and off the seat, etc., but during these actions, the overall weight is only part of the flexible sheet through the buttocks. It may be applied and the flexible sheet may be bent excessively. If such excessive sheet deflection occurs, it is considered that the massage recipient loses balance and falls. In the present invention having the above configuration, since the flexible sheet is reinforced by the flexible reinforcing band, excessive bending of the flexible sheet is prevented, so that the flexible sheet is excessively bent and the massage recipient Is prevented from falling out of balance. Furthermore, excessive bending of the flexible sheet is prevented by adding a flexible reinforcing band, and it is not necessary to modify the flexibility and rigidity of the flexible sheet. Therefore, it hardly affects the massage effect.

  In the present invention, the flexible reinforcing band is provided at a portion where the massage recipient's buttocks abuts when the massage recipient gets on and off the flexible sheet. . Usually, the fall of a massage recipient often occurs during the act of bringing only the buttocks into contact with the flexible sheet when getting on and off. Therefore, by providing a flexible reinforcing band at the part where the buttocks of massage massagers who get on and off come into contact, the excessive bending of the flexible sheet caused by the action of bringing the hips into contact with the flexible sheet at the time of getting on and off is ensured. It is possible to prevent the massage recipient from falling, and the massage recipient can easily get on and off the hydraulic massage device.

  Moreover, in this invention, there exists an aspect of setting to the minimum dimension of the extent which the buttocks of the said massage recipient who gets on and off the said dimension of the said liquid reinforcement one side direction of the said flexible reinforcement band does not protrude. According to this aspect, when the massage recipient lies down on the flexible sheet, the end of the flexible reinforcement band does not come into contact with the back portion of the massage recipient, and the massage recipient can flex to the back portion. A comfortable massage can be received without feeling uncomfortable due to the contact of the end portions of the elastic reinforcing band.

  In the present invention, a mouth portion having a mouth shape in cross section is formed at an end portion of the flexible reinforcing band, a press fitting is inserted into the mouth portion, and an edge of the liquid tank is inserted through the press fitting. There is an aspect in which the upper end is connected and fixed. According to this aspect, the end of the flexible reinforcement band is directly connected to the upper edge of the liquid tank without connecting the holding metal fitting to the upper edge of the liquid tank. Since the fixing work can be easily performed, the work efficiency can be improved. Further, since the part where the flexible reinforcement band is provided is a part where the massage recipient actually repeats getting on and off, the displacement of the flexible reinforcement band is most likely to occur. According to the above, since it is connected and fixed through the presser fitting, the flexible reinforcing band can be firmly connected and fixed to the upper edge of the edge, and the flexible reinforcing band is not easily displaced even when repeatedly getting on and off. It becomes.

  In the present invention, a female member or a male member of a double-sided fastener is provided on the flexible reinforcing band, and a female member or a male member of the flexible reinforcing band is provided on a sheet member laid on the flexible sheet. There is a mode in which a male member or a female member corresponding to is provided. According to this aspect, when the sheet member is laid on the flexible sheet surface from above the flexible reinforcing band, the female member or male member of the sheet member and the male member or female member of the flexible reinforcing band It becomes possible to fix a part of the sheet member to the flexible reinforcing band by coupling to the flexible reinforcing band.

  Further, the present invention has an aspect in which the flexible reinforcing band is made of high-performance and high-function fibers. According to this aspect, high-performance and high-performance fibers such as para-aramid fibers have a high elastic modulus, so that they do not interfere with massage and also have high strength characteristics. Even if a large and heavy massage recipient gets on and off, it can fully withstand. In addition, high-performance and high-performance fibers have impact resistance and wear resistance, and since there is little elongation due to aging deterioration with use, they can be used for a long time compared to other fibers. It is possible to avoid frequent replacement of the flexible reinforcing band, and it is economical because the running cost can be reduced.

  According to the present invention, it is possible to suppress excessive bending of the flexible sheet without causing any trouble in the massage effect. In addition, for example, natural rubber is used as the material of the flexible sheet, and a special rubber layer processed and formed on one side of this natural rubber layer (the surface on which the massage recipient gets on and off) is used as the flexible sheet. Even in this case, since the flexible reinforcement band is installed on the upper side of the flexible sheet, the natural rubber layer and the flexible reinforcement band are gradually rubbed due to repetition of the getting on and off operation of the massage recipient. There is no need to worry about the natural rubber layer being worn away.

As shown in FIG. 6, the massage recipient C sits on the upper surface of the flexible sheet 5 of the hydraulic massage apparatus 100 with the treatment site in contact with the upper surface of the sheet (for example, lying down). In this state, the massage recipient C or the massage treatment attendant D turns on the switch for starting the operation of the device 100. Then, the water absorption pump unit 13 is driven to absorb the liquid A from the liquid tank 1, pressurize the absorbed liquid A into the injection liquid B, and further generate the injection liquid B thus generated via the bent pipe 14. Then, it is pumped to the bogie passage 26 of the moving carriage 2. The injection liquid B pumped to the bogie internal flow path 26 passes through the in-axis flow paths 20Aa to 20Da and the injection section internal flow paths 21Aa to 21Da, and the first to fourth injection sections 3A to 3D. Further pressure is fed to the injection nozzles 22A to 22D. Each of the spray nozzles 22A to 22D sprays the spray liquid B that has been fed into the liquid A in the liquid tank 1 toward the opening 1a. The jetted liquid B is abutted against the back surface of the flexible sheet 5 and then diffuses into the liquid A in the liquid tank 1. At that time, the flexible sheet 5 is partially bent and deformed upward by the injection of the spray liquid B, and massages the body surface part of the massage recipient C located at the bent sheet part.

  While the jet liquid B is being jetted as described above, the drive motor 10a of the chain drive unit 10 arbitrarily rotates forward and backward, whereby the movable carriage 2 repeatedly moves linearly along the one-side direction 1b. At this time, the moving carriage 2 is guided by the linear movement of the connecting holes 25Aa and 25Ba of the first and second screw gears 25A and 25B through the shaft 9 having a rectangular cross section. Thereby, the 1st-4th injection nozzle 22A-22D of the 1st-4th injection part main bodies 21A-21D with which the mobile trolley 2 was mounted | worn repeats linear movement.

  Further, in this state, the rotation driving unit 11 drives the shaft 9 to rotate forward and backward, whereby the first and second screw gears 25A and 25B are rotated forward and backward by the shaft 9. Then, the first and second passive gears 24A and 24B interlocked with the first and second screw gears 25A and 25B are rotationally driven, whereby the first and third rotary cylinders 18A and 18C and the first The first and third connection gears 23A and 23C and the first and third injection unit main bodies 21A and 21C rotate. Further, the second and fourth connection gears 23B and 23D meshing with the first and third connection gears 23A and 23C rotate, and the second and fourth injection unit main bodies 21B and 21D rotate accordingly. . At this time, the first and third injection unit main bodies 21A and 21C and the second and fourth injection unit main bodies 21B and 21D rotate in directions opposite to each other. Thereby, the 1st-4th injection nozzles 22A-22D with which the 1st-4th injection part main bodies 21A-21D are equipped are centered on the axial center of the 1st-4th injection shaft parts 20A-20D. Rotate.

  The first to fourth injection nozzles 22A to 22D that have received the above repetitive linear movement / repetitive rotation movement move in the liquid tank 1 while drawing a complicated movement locus along the one-side direction 1b. As a result, the massage recipient C is carefully and carefully massaged by the jet liquid B ejected by the first to fourth jet nozzles 22A to 22D that move while drawing a complicated movement trajectory.

  In the hydraulic massage device 100, the flexible reinforcing band 6 is provided, and thereby the flexible sheet 5 is reinforced, so that excessive bending of the flexible sheet 5 is prevented as shown in FIG. Further, it is prevented that the flexible sheet 5 is excessively bent and the massage recipient C loses balance and falls. In FIG. 7, the shape of the flexible sheet 5 indicated by a solid line indicates the bending state of the flexible sheet 5 in the hydraulic massage device 100 of the present embodiment provided with the flexible auxiliary band 6. The shape of the flexible sheet 5 indicated by the phantom line indicates the bending state of the flexible sheet 5 in the conventional example in which the flexible auxiliary band 6 is not provided.

  In general, the fall of the massage recipient C often occurs during the act of bringing only the buttocks into contact with the flexible sheet C when getting on and off. Therefore, in the hydraulic massage device 100, the flexible reinforcing band 6 is provided at a site where the massage recipient C contacts the buttocks when the massage recipient C gets on and off the flexible sheet 5. Therefore, excessive bending of the flexible sheet 5 caused by the action of bringing only the buttocks into contact with the flexible sheet 5 when getting on and off can be surely prevented, and the massage recipient C can be prevented from falling over. Furthermore, excessive bending of the flexible sheet 5 is prevented by the addition of the flexible reinforcing band 6, and the flexibility and rigidity of the flexible sheet 5 are not modified. Therefore, excessive bending of the flexible sheet 5 is prevented without substantially affecting the massage effect.

  Moreover, in the hydraulic massage apparatus 100, since the hollow 8a is provided in the bottom part of the casing 8, the following effects are acquired. That is, at the time of getting on and off, the massage recipient C drops his / her waist on the flexible sheet 5 from the floor surface (device mounting surface) E located on the liquid tank side surface 1d along the one-side direction 1b. Stands up from the flexible sheet 5. At that time, when the massage recipient C brings the heel Ca or the toe as close as possible to the bottom of the casing 8 located on the liquid tank side surface 1d, the posture becomes stable and the operation becomes easy. In the hydraulic massage apparatus 100, the size of the massage recipient C who gets on and off the flexible sheet 5 and the toe Da of the massage treatment assistant D or the toe Da of the massage treatment attendant D enter the bottom of the casing 8 located on the liquid tank side surface 1d. The depression 8a having the above is provided. As a result, the massage recipient C can easily bring the heel Ca and the toes close to the casing 8, stabilize the posture, and easily perform the getting-on / off operation.

  Moreover, the massage treatment attendant D may approach the hydraulic massage apparatus 100 during the massage operation, and the hydraulic massage apparatus 100 may be operated or the massage recipient C may be accompanied. At that time, the toe Da of the massage treatment attendant D also enters the recess 8a, so that the massage treatment attendant D can easily approach the hydraulic massage device 100, and operation and assistance are facilitated. Furthermore, since the heel Ca and the toe of the massage recipient C or the toe Da of the massage treatment attendant D are less likely to contact the casing 8 by providing the depression 8a, the wound of the heel Ca and the toe Da caused by the casing contact. In addition, it is possible to prevent the casing 8 from being contaminated due to the contact between the heel Ca and the toe Da.

  Furthermore, in the hydraulic massage device 100, the position opposite to the heel Ca or the toe of the massage recipient C who gets on and off the flexible reinforcing band 6 from the liquid tank mounting surface E on the liquid tank side surface 1d side, and the vicinity thereof Since the dent degree of the dent 8a is larger than the dent degree of the dent at other positions, it is possible to bring the heel Ca and the toe of the massage recipient C closer to the casing 8 more reliably.

  3 shows the shape of the recess 8a in the portion where the flexible reinforcing band 6 is provided, and FIG. 4 shows the shape of the recess 8a in the portion where the flexible reinforcing band 6 is not provided.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. For example, the method of connecting and fixing the band ends 6a of the flexible reinforcing band 6 to the edge upper end 1c of the liquid tank 1 is not limited to the above-described embodiment. You may comprise so that the flexible reinforcement band 6 can be attached or detached freely with the slide type fastener etc. which were provided in 6a. This makes it easier to attach and detach the flexible reinforcing band 6, and makes it easier to care for the flexible reinforcing band 6 and to clean the flexible sheet 5 after the attachment and detachment.
