  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, the configuration of the health sitting tool 10 will be described in detail with reference to FIGS. The health sitting tool 10 according to the present embodiment includes a seat 12, a base 14, a connecting member 16, an inner rail 18, and an outer rail 20. In addition, although a detailed usage mode will be described later, the health sitting tool 10 according to the present embodiment is used by being submerged in a bathtub during bathing.

  The configuration of the sheet 12 will be described in detail with reference to FIGS. FIG. 1 is a plan side perspective view showing a configuration of a health sitting tool 10 according to an embodiment of the present invention, and FIG. 2 is a bottom side perspective view showing a configuration of the health sitting tool 10 according to an embodiment of the present invention. 3 is an enlarged sectional view taken along line AA of the health sitting tool 10 in FIG. 1, and FIG. 4 is an enlarged sectional view taken along line BB of the healthy sitting tool 10 in FIG.

  The seat 12 has a substantially rectangular parallelepiped shape as a whole, and is connected to a seat surface 12a on the top surface of the seat 12 that is curved inward so that a user can easily sit on the seat 12 and a peripheral portion of the seat surface 12a that forms the side surface of the seat 12. And a pair of gripping portions 12c provided on the short side of the peripheral wall 12b. The size of the sheet 12 excluding the grip portion 12c is 300 mm wide (long side), 150 mm long (short side), and 30 mm high. The grip part 12c protrudes 30 mm from the peripheral wall 12b in the long side direction.

  An opening 12d having a diameter of 45 mm is formed at the center of the seating surface 12a of the seat 12. In addition, an annular mounting surface 12e for mounting a flange 16a of the connecting member 16 to be described later and a cylindrical peripheral surface 12f perpendicular to the mounting surface 12e are provided therein.

  On the back surface (inner surface) side of the sheet 12, a cylindrical insertion wall 12g (inner diameter 66 mm) in which the upper half of the base 14 is accommodated is formed. Also, on the inner surface side of the sheet 12, between the outer peripheral surface of the insertion wall 12g and the inner peripheral surface of the peripheral wall 12b, ribs 12h are formed in a lattice shape for the purpose of increasing the rigidity of the sheet 12 and reducing the weight. Is formed. The end of the rib 12h on the side of the seating surface 12a is formed with a communication hole 12i for communicating adjacent spaces partitioned by the rib 12h and the seating surface 12a (and the peripheral wall 12b and the insertion wall 12g). . Therefore, the air and water in each space partitioned by the rib 12h can move to the adjacent space through the communication hole 12i.

  Further, on the back surface of the seat 12a of the seat 12 and on the inner side of the insertion wall 12g, an annular outer sliding surface 12k that abuts on a sliding surface 20b of the outer rail 20 described later, and an inner rail 18 described later. An annular inner sliding surface 12j is formed which is in contact with the sliding surface 18b and located further inside the outer sliding surface 12k.

  The seat surface 12a around the opening 12d of the seat 12 has a round hole 12l along the circumferential direction for communicating the space on the outside (upper) side and the space on the inner (lower) side of the seat surface 12a. Four are formed. Therefore, between the space inside the healthy sitting device 10 surrounded by the seat surface 12a, the insertion wall 12g, and the peripheral surface 12f of the opening 12d, and the space outside the healthy sitting device 10 through these round holes 12l, Water and air can move between each other.

  Similarly, the connecting portion between the seat surface 12a of the seat 12 and the peripheral wall 12b on the short side has six square holes 12m for communicating the space outside the seat surface 12a and the peripheral wall 12b with the inner space. Is formed. Therefore, water and air are mutually exchanged between the space inside the health sitting device 10 surrounded by the seating surface 12a, the peripheral wall 12b, and the rib 12h and the space outside the health sitting device 10 through these square holes 12m. Can be moved to.

  Next, the configuration of the base 14 will be described in detail with reference to FIG. 5 in addition to FIGS. FIG. 5 is a perspective view showing the base 14 of the health sitting tool 10 according to the present embodiment. As shown in the figure, the base 14 as a whole has a substantially disk shape (diameter 130 mm, height 35 mm). The base 14 has an arcuate lower surface 14a (see FIGS. 3 and 4) and four locking claws 14b that engage with locking holes 16c of the connecting member 16 described later. Further, the base 14 has an inner insertion portion 14c in which an annular groove into which an inner rail 18 described later is fitted is formed on the outer side of the locking claw 14b, and further on the outer side of the inner insertion portion 14c, It has the outer insertion part 14d in which the annular groove into which the outer rail 20 mentioned later is fitted was formed.

  As shown in FIG. 5, a rib 14e is formed on the lower surface 14a between the inner insertion portion 14c and the outer insertion portion 14d of the base 14 for the purpose of increasing the rigidity of the base 14 and reducing the weight. A plurality of ribs 14e are formed radially at a constant interval with the central portion of the base 14 as the center. Therefore, the space partitioned by the lower surface 14a, the inner insertion portion 14c, and the outer insertion portion 14d is further partitioned into a plurality of spaces by the ribs 14e.

  An opening 14f having a diameter of 10 mm is formed at the center of the lower surface 14a of the base 14 (see FIGS. 2 to 4). Further, as shown in FIG. 2, four long holes 14g are formed around the opening 14f. Further, a plurality of round holes 14h are formed around the long hole 14g. Air and water can move between the inside and the outside of the base 14 through the openings 14f, the long holes 14g, and the round holes 14h.

  As described above, the lower surface 14a of the base 14 has an arc shape. Therefore, the lower surface 14a of the base 14 can freely swing back and forth and right and left, for example, in a state of being placed on and in contact with the floor of the bathtub. As will be described later, the health sitting tool 10 according to the present embodiment is used in a state where the user is seated. Since the user can sit on the health sitting tool 10 and easily swing the body back and forth and right and left, the user can easily perform stretching by swinging in addition to the twisting of the waist described later.

  Next, the structure of the connecting member 16 will be described in detail with reference to FIG. 6 in addition to FIGS. FIG. 6 is a perspective view showing the connecting member 16 of the health sitting tool 10 according to the present embodiment. As shown in the figure, the connecting member 16 has an overall shape in which a disc having a diameter of 40 mm and a thickness of 2 mm is placed on a cylinder having a diameter of 30 mm and a height of 20 mm. And the connection member 16 has the flange 16a mounted in the mounting surface 12e of the sheet | seat 12, and the surrounding wall 16b perpendicular | vertical with respect to the flange 16a.

  The peripheral wall 16b is formed with four locking holes 16c in the circumferential direction at the joint with the flange 16a, and the flange 16a is formed with four holes 16d on the same circumference. As shown in FIGS. 3 and 4, with the flange 16a of the connecting member 16 mounted on the mounting surface 12e of the sheet 12, the locking hole 16c of the solid member 16 and the locking claw 14b of the base 14 are engaged. By combining, the seat 12 and the base 14 are integrally combined so as to be relatively rotatable with an inner rail 18 and an outer rail 20 described later interposed therebetween.

  Next, the configuration of the inner rail 18 and the outer rail 20 will be described in detail with reference to FIGS. 7 and 8. FIG. 7 is a perspective view showing the inner rail 18 of the health sitting tool 10 according to the present embodiment. As shown in the figure, the inner rail 18 has a ring shape with an inner diameter of 60 mm and a band width of 5 mm. On the upper surface 18a, concave portions (thickness 2 mm) and convex portions (thickness 4 mm) are alternately formed along the circumferential direction. As described above, the inner rail 18 is placed in the annular groove of the inner insertion portion 14c of the base 14, and when the seat 12 and the base 14 are combined, the upper surface 18a of the inner rail 18 contacts the inner sliding surface 12j of the seat 12. The bottom surface 18b comes into contact with the inner insertion portion 14c of the base 14 and is sandwiched.

  FIG. 8 is a perspective view showing the outer rail 20. As shown in FIG. 8, the outer rail 20 has a ring shape with an inner diameter of 114 mm and a band width of 5 mm. On the upper surface 20a, concave portions (thickness 2 mm) and convex portions (thickness 4 mm) are alternately formed along the circumferential direction. As described above, the outer rail 20 is placed in the annular groove of the outer insertion portion 14d of the base 14, and when the seat 12 and the base 14 are combined, the upper surface 20a of the outer rail 20 contacts the outer sliding surface 12k of the seat 12. The bottom surface 20b comes into contact with the outer insertion portion 14d of the base 14 and is sandwiched therebetween.

  The inner rail 18 and the outer rail 20 are both in contact with the sliding surfaces 12j, 12k and the insertion portions 14c, 14d so as to be relatively rotatable, but the upper surface 18a having the uneven portions of the rails 18, 20 is provided. 20a and the sliding surfaces 12j and 12k are smaller than the contact areas between the lower surfaces 18b and 20b and the insertion portions 14c and 14d. Therefore, when the seat 12 and the base 14 are relatively rotated, the rails 18 and 20 and the seat 12 having a smaller friction when sliding are more effective than the rails 18 and 20 and the base 14. Many relatively rotate.

  Although the structure of the health sitting tool 10 according to the present embodiment has been described above, the members of the seat 12, the base 14, the connecting member 16, the inner rail 18, and the outer rail 20 constituting the health sitting tool 10 are each made of plastic. It is molded integrally with the material. Since the health sitting tool 10 is intended for use in water such as in a bathtub, a material that easily rusts in water such as metal is not used.

  Specifically, the plastic material forming the sheet 12, the base 14, and the connecting member 16 is a material that is hard and resistant to bending, has high heat resistance, and has a slightly lower specific gravity than water. Polypropylene (specific gravity ≈ 0.91, heat resistance ≈ 110 ° C) is used.

  Further, the plastic material forming the inner rail 18 and the outer rail 20 has heat resistance and cold resistance, can withstand repeated loads, has low hygroscopicity, does not decrease mechanical strength even at high temperature and high humidity, and has friction. Polyacetal (specific gravity ≒ 1.41) is used which has a low coefficient and excellent wear resistance.

  The specific gravity of the health sitting tool 10 as a whole is 1 which is almost the specific gravity of water. The specific gravity of hot water of about 40 ° C in the bathtub is about 0.01 smaller than the specific gravity of water (= 1). The specific gravity of hot water is the same as the specific gravity of water. Moreover, the water described in this specification means a broad concept including hot water, hot water in which a bath agent is dissolved, and the like.

  As described above, since the specific gravity of the health sitting device 10 as a whole is substantially the same as that of water, when the health sitting device is submerged in water, almost all the air inside the health sitting device 10 escapes as described later. The buoyancy hardly acts on the health sitting tool 10, and it does not float or sink.

  In addition, the material of each member which comprises a healthy sitting tool is not limited to the said material, It can change suitably. For example, as the seat 12, the base 14, the connecting member 16, the inner rail 18, and the outer rail 20, high density polyethylene (HDPE, specific gravity≈0.96) having the same properties as polypropylene can be used. However, it is preferable that the specific gravity of the health sitting tool 10 as a whole is substantially equal to the specific gravity of water. Here, the specific gravity substantially equal to the specific gravity of water means that it is larger than 0.9 and smaller than 1.1.

  The configuration of the health sitting tool 10 according to the present embodiment has been described above. Next, the operation state of the health sitting tool 10 will be described in detail. FIG. 9 is a diagram showing an operating state of the health sitting tool 10 according to the present embodiment. As shown in FIG. 9, the health sitting tool 10 is configured so that the seat 12 can be rotated in the circumferential direction (the direction of the arrow in FIG. 9) with respect to the base 14 around the connecting member 16. Moreover, it is comprised so that it can rotate also to a reverse direction.

  As described above, since the user sits on the seat 12 and uses the health sitting tool 10 after sinking in the bottom of the bathtub, the health sitting tool 10 is rotated relative to the base 14 to which the seat 12 is connected. Will move. At this time, as described above, the inner sliding surface 12j and the outer sliding surface 12k of the seat 12 slide on the upper surface 18a of the inner rail 18 and the upper surface 20a of the outer rail 20 attached to the base 14. Rotate.

  The health sitting device 10 according to the present embodiment is configured such that the seat 12 is rotated 360 ° to the left and right with respect to the base 14, but the usage mode in which the user sits and twists the waist. In view of the above, for example, it may be configured so that it can be rotated within a range where the waist is twisted, such as rotating about 60 ° to the left and right.

  Next, the usage aspect of the health sitting tool 10 comprised in this way is demonstrated in detail with reference to FIG.10 and FIG.11. FIG. 10 is a schematic cross-sectional view showing how the health sitting tool 10 according to the present embodiment is used, and FIG. 10 (a) is a diagram showing a state where the health sitting tool 10 is floated inside the bathtub 30. 10 (b) is a view showing a state where the inside of the bathtub 30 has been sunk. Here, in order to explain the state in which the air in the health sitting tool 10 goes out to the outside, the user can keep the health sitting tool 10 horizontal with the upper surface of the seat 12 facing upward, The case where it sinks in will be described as an example.

  As shown in FIG. 10A, the user puts the health sitting tool 10 in the bathtub 30 with the grip portion 12 c so that the seating surface 12 a of the seat 12 faces up. Next, as shown in FIG.10 (b), a user sinks the healthy sitting tool 10 toward the bottom face part 30a of the bathtub 30 (direction of arrow S of FIG. 10). When the health sitting tool 10 is initially submerged in the water, air accumulates in the space partitioned by the ribs 12h inside the seat 12, the space partitioned by the ribs 14e inside the base 14, and the like. Has a large buoyancy. Therefore, the user needs to sink the health sitting tool 10 against this buoyancy.

  However, the health sitting tool 10 according to the present embodiment includes an opening 12d, a communication hole 12i, a round hole 12l, a square hole 12m, an opening as air holes for extracting the air accumulated in the health sitting tool 10 to the outside. 14f, a long hole 14g, a round hole 14h, a hole 16d, and the like are provided, and water flows into the health sitting tool 10 and the air in the health sitting tool 10 escapes to the outside through any of the air holes.

  Here, the effect | action which the air collected in the space partitioned off by the rib 12h of the sheet | seat 12 escapes outside is demonstrated in detail. The air accumulated in the space partitioned by the ribs 12h passes through the communication holes 12i formed in the ribs 12h of the sheet 12 and moves to the endmost space (in the direction of arrow N in FIG. 10). This is because the back side of the seating surface 12 a of the seat 12 is curved so that both end portions are higher than the center portion of the seat 12. The air that has moved to the endmost space, that is, the space surrounded by the seating surface 12a, the rib 12h, and the peripheral wall 12b of the seat 12 escapes from the square hole 12m to the outside of the seat member (arrow N in FIG. 10). Direction).

  Thus, since the buoyancy hardly acts on the healthy sitting tool 10 from which the air has escaped, the user can easily sink to a position (not shown) in contact with the bottom surface portion 30a of the bathtub 30. In addition, when large buoyancy acts on the health seat, after sinking in the bathtub, when the user sits on the health seat or when the user stretches the waist using the health seat In some cases, the health sitting device may be very difficult to use, but with the health sitting device according to the present embodiment, the buoyancy that acts on the health sitting device after the air inside is removed. This problem can be solved since almost all of the problem is eliminated.

  Further, in order to reduce the weight while maintaining the strength of the seat 12, the air in the space partitioned by the rib 12h provided on the back side of the seating surface 12a is transferred to the end of the seat 12 by the communication hole 12i provided in the rib 12h. Since it is configured to be pulled out through the square holes 12m at the end after being collected, it is necessary to provide a number of holes for allowing air to escape in the seating surface 12a for each space partitioned by the ribs 12h. Absent. That is, the number of air holes formed in the seating surface 12a of the seat 12 is small, the design is neat, and the user's seating comfort can be remarkably improved.

  Subsequently, FIG. 11 is a diagram schematically showing a use state of the health sitting tool 10 according to the present embodiment. As shown in FIG. 11, the user extends his leg with his knees slightly bent and sits on the seating surface 12 a of the seat 12 of the health sitting tool 10. When the knee is swung left and right in this posture, the seat 12 rotates in the circumferential direction while the base 14 of the health sitting tool 10 is fixed to the bottom of the bathtub. Thereby, the waist is also rotated left and right, so that a stretching effect can be obtained.

  As described above, according to the health sitting tool 10 according to the present embodiment described in detail, the user simply puts the health sitting tool 10 in the hot water of the bathtub 30 and presses it with a little force, so that the bottom of the bathtub can be easily obtained. You can sink towards.

  In addition, the health sitting tool 10 according to the present embodiment is formed with a number of air holes for extracting air accumulated inside when the health sitting tool 10 is submerged in the bathtub. A large buoyancy can be prevented from acting on the health sitting tool 10. Therefore, the user forcibly presses down on a healthy sitting tool that is about to rise due to a large buoyancy, or when the user sits and twists the waist, the healthy sitting tool rises when the buttocks float slightly. Without using it, it is possible to use a healthy seat.

  Furthermore, the health sitting tool 10 according to the present embodiment is configured such that the specific gravity as a whole is substantially the same as the specific gravity of water. Therefore, when the healthy sitting tool 10 is submerged in a predetermined position in the bathtub 30, the buoyancy applied to the healthy sitting tool 10 becomes almost zero after the air in the interior is almost removed from the air hole, and the vicinity of the submerged place. It can be left behind. Therefore, the user can use the health sitting tool 10 more stably. In addition, when hot water is cloudy particularly with a bath agent or the like, it is possible to prevent the body from sinking to the bottom of the bathtub and being difficult to find when trying to take out a healthy sitting tool.

  In the present embodiment, it goes without saying that various modifications can be made without departing from the spirit of the present invention. For example, in the present embodiment, the case where the health sitting tool is submerged in a bathtub and used in water has been described, but of course, the use is not limited to the use in water, and the user may select an appropriate place for use.

  In the present embodiment, the grid-like ribs 12h are formed on the back side of the sheet 12. However, the ribs are not limited to the grid shape, and may be annular or radial ribs.

  In the present embodiment, the air accumulated in the seat 12 is guided to both ends of the seat 12 using the curved surface on the back side of the seat 12a. However, the thickness of the seat 12a is not limited. The air may be moved to the central portion of the seating surface 12a or another predetermined location by changing the position depending on the location. Then, an air hole for guiding the air that has moved to the predetermined location to the outside of the sheet 12 may be formed in the sheet 12 at the predetermined location.

  In addition, an opening 12d, a communication hole 12i, a round hole 12l, a square hole 12m, an opening 14f, a long hole 14g, a round hole 14h, a hole 16d, and the like as air holes for extracting the air accumulated in the health seat 10 to the outside The position, number, shape, etc. can be changed as appropriate. For example, in the present embodiment, the air accumulated in the space partitioned by the ribs 12h of the sheet 12 is configured to be guided to the outside after being moved to the space at the extreme end of the sheet 12, You may comprise so that an air hole may be provided in the position of the seat surface 12a corresponding to the partitioned space, respectively, and air may be directly extracted from each space to the exterior. However, it is necessary to install air holes of a position, shape, and number that can efficiently extract the air accumulated in the health sitting tool 10 to the outside.

  In addition, although the air hole for extracting air is not provided in the grip portion 12c of the sheet 12, an air hole may be provided on the upper surface of the grip portion or the like. Moreover, although it becomes difficult for a user to carry the health sitting tool 10, it is good also as a structure which does not provide the holding part 12c itself.

  Moreover, although the health sitting tool 10 which concerns on this Embodiment comprised from the sheet | seat 12, the base 14, the connection member 16, the inner rail 18, and the outer rail 20, it is limited to such a structure. Rather, it is a health seat that has a base that is fixed to a fixed surface such as a bathtub bottom or a floor, and a seat that a user sits on, and even a seat that is rotatably held relative to the base. It ’s fine. However, when the health sitting tool is submerged in water, it is necessary to appropriately form air holes in the base and the seat for extracting the air accumulated in the base and the seat to the outside. More preferably, it is necessary to appropriately select the material of the members constituting the health sitting device so that the specific gravity of the whole health sitting device is approximately the same as that of water.
