Description

  The present invention relates to a bathtub device, and more particularly, to a bathtub device that allows a bather to exercise.

  In recent years, the health-consciousness has increased, and there has been an increasing demand for health management through exercise such as fitness and exercise. There is also a desire to exercise easily while taking a bath.

  For example, Patent Document 1 discloses a technique for providing a step that can be stepped into a bathtub. A stepping load is applied to the step board by a spring, and the bather can exercise by stepping on the step board with one foot while sitting. However, a person who does not usually have exercise habits needs considerable will power to exercise. In particular, when taking a bath, it is difficult to exert the power of the will because it is in a relaxed mental state. For this reason, even if exercise equipment is installed in the bathtub, it is expected that the exercise will not last long. In addition, the apparatus described in Patent Document 1 can exercise only the lower limbs of bathers, but in recent years, it has been known that the effect of exercise is improved by the whole body exercise, particularly the coordinated exercise of the lower limb and the upper limb.

And a grasping unit.

  ADVANTAGE OF THE INVENTION According to this invention, the bathtub apparatus which can make a bather continuously exercise the whole body is realizable.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, a first embodiment of the present invention will be described.
FIG. 1 is a schematic view illustrating a bathtub device according to this embodiment.
FIG. 2 is a side view illustrating the upper limb swinging means in the present embodiment.

  As shown in FIG. 1, in the bathtub apparatus 11 which concerns on this embodiment, the bathtub 12 is provided. The shape of the bathtub 12 is, for example, a substantially rectangular parallelepiped shape, and the inner side surface of one end portion in the longitudinal direction is a foot side surface 12a that the sole m1 faces when the bather M takes a bathing posture. The inner side surface of the other end is a back side surface 12b with which the back m2 of the bather M contacts. The back side surface 12b, which is the second inner side surface, faces the foot side surface 12a, which is the first inner side surface. That is, the foot side surface 12a and the back side surface 12b are opposed to each other with the bottom surface 12c interposed therebetween. Moreover, in the bathtub 12, the inner surface of the both ends of the width direction orthogonal to a longitudinal direction becomes a pair of side surface 12d. That is, the pair of lateral side surfaces 12d that are the third inner side surfaces are provided between the foot side surface 12a and the back side surface 12b and face each other. And the inner surface of the bathtub 12 is comprised from the foot side surface 12a, the back side surface 12b, and a pair of side surface 12d.

  An ejection portion 13 is provided on the foot side surface 12 a of the bathtub 12. The ejection part 13 injects a water flow intermittently toward the inside of the bathtub 12, and the direction of this water flow is a direction from the foot side surface 12a to the back side surface 12b. For example, two ejection portions 13 are provided and are arranged in the horizontal direction. The ejection part 13 is, for example, a nozzle, and the interval is about the interval between human feet.

  In addition, a pump 14 is provided outside the bathtub 12 in the bathtub apparatus 11. Piping on the water absorption side of the pump 14 is communicated with the inside of the bathtub 12. Thereby, the pump 14 draws water out of the bathtub 12, produces | generates and discharges a water flow. Furthermore, the water discharge control means 15 which supplies the water flow produced | generated by the pump 14 intermittently with respect to the ejection part 13 in the exterior of the bathtub 12 in the bathtub apparatus 11 is provided. The water discharge control means 15 is provided with a mechanism unit 15a for switching the water flow and a switching control unit 15b for controlling the operation of the mechanism unit 15a, which are interposed in the water channel between the pump 14 and the ejection unit 13. The mechanism unit 15a is a mechanical device, and the switching control unit 15b is an electronic device.

  The magnitude of the water flow ejected from the ejection part 13 is such that when the bather M brings the back m2 into contact with the back side surface 12b and the sole m1 faces the ejection part 13, the ankle a1 and the knee of the bather M The size is such that the joint a2 and the hip joint a3 can be bent at the same time, for example, 80 to 300 liters / minute. In addition, when the magnitude | size of a water flow is less than 80 liters / minute, it is difficult to bend the ankle joint a1, the knee joint a2, and the hip joint a3 simultaneously, and when it exceeds 300 liters / minute, water may jump out of the bathtub 12. is there. The preferred water flow size is 120 to 270 liters / minute, more preferably 150 to 250 liters / minute.

  Furthermore, the bathtub device 11 is provided with upper limb swinging means 16. The upper limb swinging means 16 is provided with a pair of support portions 17 and a pair of grasping portions 18. Each support portion 17 is attached to each lateral side surface 12 d of the bathtub 12, and is thereby fixed to the bathtub 12. Further, each grasping portion 18 is swingably connected to each support portion 17. In this specification, “oscillation” refers to a movement in which at least one of position, velocity, and angle changes within a certain range, and is at least in a rotational motion, a reciprocating linear motion, and a partial area of a spherical surface. Including free movement in The grasping part 18 is arranged at a position where the bather M can grasp with both hands when taking a bathing posture.

  Specifically, as shown in FIG. 2, in the support portion 17, a rail 17 a extending in the longitudinal direction of the bathtub 12 is laid on the lateral side surface 12 d of the bathtub 12. Each grasping portion 18 is provided with a gantry 18a and a lever 18b. The gantry 18a is a plate-like member that is movable along the rail 17a in the longitudinal direction of the bathtub 12, that is, in the direction connecting the foot side surface 12a and the back side surface 12b. The lever 18b is a rod-like member extending from the gantry 18a in the width direction of the bathtub 12. In the present embodiment, the left and right grasping portions 18 can move independently of each other.

  A stopper 19 is provided on the gantry 18 a of the grasping unit 18. The stopper 19 is movable within a certain range with respect to the gantry 18a. When the stopper 19 is pushed into the gantry 18a, the tip of the stopper 19 comes into contact with the rail 17a and fixes the gantry 18a to the rail 17a. On the other hand, when the stopper 19 is pulled out with respect to the gantry 18a, the stopper 19 is separated from the rail 17a and does not obstruct the movement of the gantry 18a. Thus, the stopper 19 functions as a lock mechanism unit that fixes the grasping unit 18 to the support unit 17.

Next, the operation of this embodiment will be described.
In the present embodiment, the upper limbs of the bather each translate along the longitudinal direction of the bathtub.
In a state where water (hot water) is put in the bathtub 12, the bather M enters the bathtub 12 and takes a bathing posture. The bathing posture refers to a posture in which the bather M brings the buttocks into contact with the bottom surface 12c of the bathtub 12, the back m2 contacts the back side surface 12b of the bathtub 12, and the sole m1 faces the foot side surface 12a. And the bather M opposes the right and left soles to the right and left ejection parts 13, respectively. Moreover, the lever 18b of the grasping part 18 is grasped with both hands. At this time, the stopper 19 is pulled out from the gantry 18 a, and the grasping part 18 is movable with respect to the support part 17. Furthermore, it is assumed that the bather M is in a relaxed state and the ankle joint a1, the knee joint a2, and the hip joint a3 are weakened.

  In this state, the pump 14 pumps up the water in the bathtub 12 to generate a water flow and supplies it to the water discharge control means 15. In addition, the switching controller 15 a of the water discharge controller 15 controls the mechanism 15 b to supply water flow intermittently to the ejection unit 13. For example, the water discharge control means 15 supplies a water flow to the left and right ejection parts 13 alternately. Thereby, a water flow is alternately ejected from the right and left ejection parts 13. That is, the water flow is intermittently ejected from each ejection portion 13, but the phases are opposite to each other between the left and right ejection portions 13.

  When a water flow is jetted from the ejection part 13, this water flow presses the sole m1 of the bather M. As a result, the ankle joint a1, the knee joint a2 and the hip joint a3 of the bather M are bent at the same time, and the foot moves toward the back side surface 12b. On the other hand, when the water flow is no longer ejected from the ejection portion 13, the pressure that presses the sole disappears, so that the ankle joint a1, the knee joint a2 and the hip joint a3 naturally stretch, and the foot moves toward the foot side surface 12a, It returns to the vicinity of the ejection part 13. Therefore, the bather's feet reciprocate along the longitudinal direction of the bathtub 12 by the jetting unit 13 ejecting the water flow intermittently. Further, by alternately ejecting water flow from the left and right ejection parts 13, the left and right feet reciprocate in opposite phases, and a movement simulating walking is possible. At this time, the water flow that presses the sole m1 of the bather M flows around the foot and flows toward the back side surface 12b. As a result, since the foot is in a state of being surrounded by a water flow, it is difficult to come off from the path of the water flow, and a trajectory along the water flow is taken.

  And when one foot sole of the bather M is pressed and a leg part is bent, a waist | hip | lumbar will rotate and the other arm will try to move ahead. For example, in the example shown in FIG. 1, when the sole of the right foot of the bather is pressed by a water flow, the right ankle joint, knee joint, and hip joint are bent. As a result, the bather's waist rotates clockwise as viewed from above, and the left leg and left arm naturally move forward, and the right arm descends backward. At this time, both hands of the bather are holding the lever 18b of the grasping portion 18, but since the lever 18b is movable along the rail 17a, both arms of the bather are not restrained. For this reason, when the bather's left arm tries to move forward, the movement is not blocked and the left arm moves forward. When the right arm tries to move backward, the movement is not blocked and the right arm moves backward. On the other hand, when the bather's left sole is pressed by water, the left ankle, knee, and hip are bent, the hips rotate counterclockwise when viewed from above, and the right leg and right arm are in front And the left arm goes back.

  In this way, when the water flow is alternately ejected from the left and right ejection portions 13, the bather's left and right feet reciprocate in opposite phases, and accordingly, the bather's waist reciprocally rotates. The left and right arms reciprocate in opposite phases. As a result, it is possible to cause the bather M to perform whole body exercise in which the lower limb (leg) and the upper limb (arm) are coordinated.

  On the other hand, when the bather moves only the lower limb and does not want to move the upper limb, the grasping portion 18 can be fixed to the support portion 17 by pushing the stopper 19 into the gantry 18a. Thereby, only the lower limbs (legs) can be exercised while the upper limbs (arms) are fixed to the bathtub.

Next, the effect of this embodiment will be described.
As described above, according to the present embodiment, the jet part 13 intermittently jets the water flow, so that the foot joint a1, the knee joint a2, and the hip joint a3 of the bather M are bent and stretched. At this time, both hands of the bather are grasping the lever 18b and can move freely in the longitudinal direction of the bathtub 12, so that the water flow presses the soles of the bathers and turns the waist. Can move and exercise arms. Thereby, the bather M can be made to exercise the whole body in which the lower limb and the upper limb are coordinated. At this time, the right and left jetting parts 3 alternately jet water, thereby alternately bending and stretching the left and right legs of the bather, reciprocating the hips, and reciprocating the left and right arms back and forth alternately. Can do. As a result, the water flow ejected from the ejection portion 13 swings the bather's leg, and the lever 18b can activate the muscles associated with the upper limb, the forearm, and the upper arm. In this way, by activating the muscle groups such as the upper limbs, it is possible to increase the number of muscle groups that are active compared to the case where only the legs are exercised, the energy consumption is increased, and the exercise effect is further improved. .

  In recent studies, it has been reported that the active level of the leg muscles unrelated to the arm muscles increases by actively moving the arms. Therefore, by exercising the upper and lower limbs in a coordinated manner, the exercise effect is improved more than simply increasing the amount of active muscles. Further, by providing the lever 18b, the upper limb exercise becomes more rhythmic, and the bather M can be made to perform an exercise simulating walking. Furthermore, since the balance of posture is lost by this exercise, the bather M performs the compensation operation by unconsciously using the muscles of the whole body, but can also exercise by this.

  Thus, according to this embodiment, the bather M can be exercised. Since this exercise is a passive movement exercised from the outside and is not an automatic exercise performed according to the will of the bather, there are few parts depending on the will of the bather, and it tends to last for a long time. Further, since this exercise can be performed while taking a bathing posture, the bather can exercise in a relaxed state. As a result, it is easy to continue exercise. The “passive motion” refers to a motion performed by a person using an external force instead of his / her own muscular strength, and in this specification, it includes a compensation operation when the posture is lost as described above.

  In addition, according to the present embodiment, from the viewpoint of expanding the movable range of the passive movement by the water flow, the operation of the upper limb swinging means 16 can cause the bather to perform the whole body movement in which the lower limb and the upper limb are coordinated. it can. As a result, a dynamic exercise can be performed as compared with a case where only the lower limbs are exercised, and a higher exercise effect can be obtained.

  Further, in the present embodiment, the stopper 19 is provided as the lock mechanism portion, so that the bather selects whether the grasping portion 18 is movable or fixed depending on the purpose of exercise or the physical condition of the bather. can do.

  Furthermore, the exercise effect is further improved by the thermal effect of bathing. Furthermore, since the temperature boundary layer around the bather is always destroyed by the water flow, the bather is easily warmed, and the exercise effect is further improved. As described above, by performing the above-described exercise in the bathtub, a higher exercise effect can be obtained as compared with the case of performing the exercise outside the bathtub.

Next, a second embodiment of the present invention will be described.
In the present embodiment, the bather's upper limb rotates.
FIG. 3 is a schematic view illustrating the bathtub device according to this embodiment.
FIG. 4 is a side view illustrating the upper limb swinging means in the present embodiment.
As shown in FIGS. 3 and 4, the present embodiment is different from the first embodiment in the configuration of the upper limb swinging means. Also in the bathtub device 21 according to the present embodiment, the upper limb swinging means 26 is provided with a pair of support portions 27 and grasping portions 28 as in the first embodiment described above. Is attached to the lateral side surface 12 d of the bathtub 12, and the grasping portion 28 is swingably connected to the support portion 27.

  Hereinafter, the configuration of the upper limb swinging means 26 will be described. As shown in FIG. 4, the support 27 is provided with a base 27a attached to the lateral surface 12d of the bathtub 12, and a shaft 27b stands from the base 27a. The direction in which the shaft 27b extends is a direction perpendicular to the lateral side surface 12d. A screw thread (not shown) is formed on the outer peripheral surface of the tip portion of the shaft 27b, and an annular stopper 29 is screwed so as to surround the tip portion of the shaft 27b.

  On the other hand, the grasping portion 28 is provided with a rod-like rotation lever 28a, and an annular portion 28b is provided at one end of the rotation lever 28a. The shaft 27b of the support portion 27 is fitted into the opening of the annular portion 28b, whereby one end of the grasping portion 28 is pivotally supported by the shaft 27b. At this time, the annular portion 28 b is disposed between the base 27 a and the stopper 29.

  And if the stopper 29 is loosened and a clearance is provided between the annular portion 28b, the grasping portion 28 is rotatable with respect to the shaft 27b. That is, the tip of the rotary lever 28a can move circularly about the shaft 27b, and can move in the longitudinal direction and the vertical direction of the bathtub 12. On the other hand, when the stopper 29 is tightened and the annular portion 28b is sandwiched between the stopper 27 and the base 27a, the grasping portion 28 is fixed to the support portion 27. Thus, the stopper 29 functions as a lock mechanism unit that fixes the grasping unit 28 to the support unit 27. Moreover, the grasping part 28 has a rotating lever 28a whose one end is pivotally supported by the shaft 27b so as to be rotatable or rotatable. Other configurations in the present embodiment are the same as those in the first embodiment.

Next, the operation of this embodiment will be described.
The bather M takes a bathing posture in the bathtub 12 and holds the rotating lever 28a of the grasping unit 28 with both hands. At this time, the stopper 29 is in a loosened state, and the rotation lever 28a is rotatable with respect to the shaft 27b. In this state, the pump 14 and the water discharge control device 15 are operated, and the left and right soles of the bather M are alternately pressed by alternately injecting the water flow from the left and right injection units 13, and the left and right legs are alternately switched. Bend and stretch. At this time, both hands of the bather are holding the rotation lever 28a, but the rotation lever 28a is rotatable about the shaft 27b, so both arms of the bather are not restrained and synchronize with the movement of the legs. Move.

  Then, by alternately ejecting water flow from the left and right ejection parts 13, when the bather's left and right feet reciprocate in opposite phases, the bather's waist reciprocates and revolves, The left and right arms reciprocate in opposite phases. As a result, it is possible to cause the bather M to perform whole body exercise in which the lower limb (leg) and the upper limb (arm) are coordinated. On the other hand, when the bather moves only the lower limbs and does not want to move the upper limbs, the grasping portion 28 can be fixed to the support portion 27 by tightening the stopper 29. Thereby, only the lower limbs (legs) can be exercised while the upper limbs (arms) are fixed to the bathtub.

  Thus, also in the present embodiment, the bather M can be caused to exercise the whole body as in the first embodiment described above. In addition, since this exercise is a passive exercise, it tends to last long. Furthermore, according to the present embodiment, as shown in FIG. 3, the direction in which the rotation shaft 27b of the rotation lever 28b extends and the direction in which the rotation shaft of the joint connecting the forearm portion and the upper arm portion of the bather's upper limb extend are defined. It will be the same. And by such a rotational movement of the upper limb, the muscle group of the upper limb can be activated more effectively than the translational movement of the upper limb along the longitudinal direction of the bathtub as in the first embodiment. As a result, the overall energy consumption can be improved, and the exercise effect can be increased.

  Operations and effects other than those described above in the present embodiment are the same as those in the first embodiment described above. In the present embodiment, an example in which the grasping portion 28 is rotatable with respect to the support portion 27 has been described. However, the present invention is not limited to this, and a certain restriction is imposed on the movable angle of the grasping portion 28. Also good. In this case, the grasping part 28 is rotatable within a certain angle range set with respect to the support part 27.

Next, a third embodiment of the present invention will be described.
In the present embodiment, the upper limb of the bather is caused to perform a rotational motion and a translational motion simultaneously.
FIG. 5 is a schematic view illustrating the bathtub device according to this embodiment.
FIG. 6 is a cross-sectional view illustrating the upper limb swinging means in the present embodiment.
As shown in FIGS. 5 and 6, the present embodiment differs from the first and second embodiments described above in the configuration of the upper limb swinging means. Also in the bathtub apparatus 31 according to the present embodiment, as in the first and second embodiments described above, the upper limb swinging means 36 is provided with a pair of support portions 37 and a grasping portion 38. The support portion 37 is attached to the lateral side surface 12 d of the bathtub 12, and the grasping portion 38 is swingably connected to the support portion 37 by a ball joint 35.

  Hereinafter, the configuration of the upper limb swinging means 36 will be described. As shown in FIG. 6, the support portion 37 is provided with a base 37 a and is attached to the lateral side surface 12 d of the bathtub 12. A spherical cavity 37b is formed in the base 37a. The hollow portion 37b communicates with the outside of the base 37a, that is, the inside of the bathtub 12, through an opening 37c formed in the base 37a. On the other hand, the grasping portion 38 is provided with a rod-shaped lever 38a, and a spherical spherical portion 38b is provided at one end of the lever 38a. The diameter of the spherical portion 38b is slightly smaller than the inner diameter of the hollow portion 37b. The spherical portion 38b of the grasping portion 38 is fitted into the hollow portion 37b of the support portion 37, and the lever 38a is inserted from the hollow portion 37b to the outside of the base 37a, that is, inside the bathtub 12 through the opening portion 37c. Has been pulled out. The ball joint 35 is configured by the hollow portion 37b and the spherical portion 38b.

  The upper limb swinging means 36 is provided with a stopper 39. The stopper 39 is slidable with respect to the outer surface of the base 37a. When the stopper 39 is positioned at one end of the movable range, the tip end portion extends over the opening 37c, and the lever 38a is sandwiched between the end edge of the opening 37c. Thereby, the lever 38 a can be fixed to the support portion 37. On the other hand, when the stopper 39 is positioned at the other end of the movable range, the tip portion is retracted to the outside of the opening 37c, and the stopper 39 is not interposed in the moving range of the lever 38a. As a result, the end portion of the lever 38a on the side where the spherical portion 38b is not attached can freely move within the curved surface region forming a part of the sphere. Other configurations in the present embodiment are the same as those in the first embodiment.

  In the present embodiment, since the lever 38a freely moves around the spherical portion 38b, the bather M grasps the lever 38a with both hands when taking a bath, so that the bather M realized in the first embodiment is used. Both the translational movement of the upper limbs (upper arm, forearm) and the rotational movement of the upper limb (upper arm, forearm) of the bather M realized in the above-described second embodiment can be realized. Thereby, both the muscle group which works positively in translational movement, and the muscle group which works positively by rotational movement can be activated. As a result, the amount of energy consumption is greater than in the first or second embodiment, and the bather M can perform more effective exercise. Operations and effects other than those described above in the present embodiment are the same as those in the first embodiment described above.

Next, a fourth embodiment of the present invention will be described.
FIG. 7 is a schematic view illustrating the bathtub device according to this embodiment.
As shown in FIG. 7, in the bathtub apparatus 41 according to the present embodiment, in addition to the configuration of the bathtub apparatus 11 (see FIG. 1) according to the first embodiment described above, the interlock that links the left and right grasping units 18. Means are provided. For this reason, in the present embodiment, the right and left grasping units 18 do not operate independently of each other, but are interlocked.

  In the interlocking means, a tube (not shown) is laid so as to pass the outside of the bathtub 12, for example, the outer peripheral portion on the back side surface 12b side, and the wire 42 is inserted into the inside of the tube. Both ends of the wire 42 are connected to the left and right grasping portions 18 respectively. Thereby, as shown in FIG. 7, when one grasping portion 18 of the left and right grasping portions 18 is pulled and moved rearward (back side surface 12 b side), the grasping portion 18 presses the wire 42, The wire 42 presses the other grasping portion 18, and the other grasping portion 18 moves forward (to the side of the foot side surface 12a). When one grasping part 18 is pushed forward and moves, the grasping part 18 pulls the wire 42, the wire 42 pulls the other grasping part 18, and the other grasping part 18 moves rearward. Thereby, the right-and-left grasping part 18 always moves in an opposite phase, and the bather M can be made to perform dynamic exercise including rotation of the waist. That is, by using a reciprocating structure in which the upper limb swinging means moves the other grasping portion 18 by using the movement of one grasping portion 18 as a power, it is possible to give a stable rocking to the bather's upper limb and consequently to the whole body. It becomes. Other configurations, operations, and effects of the present embodiment are the same as those of the first embodiment.

  In addition, the laying position of the wire is not limited to the side of the back side surface 12b, and may be laid on the side of the foot side surface 12a. Also, in the second and third embodiments described above, interlocking means can be provided as in this embodiment. For example, in the second embodiment described above (see FIGS. 3 and 4), the rotation angle of the grasping unit 28 is regulated so that the grasping unit 28 rotates within a certain angle range. The wire may be wound or unwound with movement. In this case, the wire may pass below the bathtub 12.

  While the features of the present invention have been described above with reference to the embodiments, the present invention is not limited to these embodiments. That is, even if a person skilled in the art adds, omits, or changes a design to the bathtub device according to any one of the embodiments and any combination of the embodiments described above, Any device having the gist of the invention is included in the scope of the present invention. For example, in each of the above-described embodiments, an example in which the upper limb swinging means is provided with a stopper as a lock mechanism portion is shown, but the present invention is not limited to this, and the stopper may be omitted. Further, the upper limb swinging means may be provided with an adjusting means for adjusting a load and an operating range when the grasping unit operates. Further, in each of the above-described embodiments, an example in which two ejection portions are provided has been described. However, the present invention is not limited to this, and the number of ejection portions may be one or three or more. Furthermore, in each of the above-described embodiments, the example in which the support portion of the upper limb swinging means is attached to the lateral side surface of the bathtub is shown, but the present invention is not limited to this, for example, a bathroom wall or ceiling For example, a rope-like member may be suspended from the ceiling of the bathroom.
