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.

JP 2003-236014 A

  The objective of this invention is providing the bathtub apparatus which can make a bather exercise continuously.

  According to one aspect of the present invention, a bathtub, a jet section that is provided on the first inner surface of the bathtub, and intermittently injects a water flow toward the inside of the bathtub, and the first in the bathtub. Leg stabilizing means provided on the inner side surface portion, and the size of the water flow is such that the bather makes the back abut the second inner side surface facing the first inner side surface, When the sole of the foot is opposed to the ejection part, the bather's ankle joint, knee joint and hip joint are sized to bend, and the leg stabilizing means is intermittently ejected. There is provided a bathtub device that guides the foot so that it does not deviate from the path of the water flow when the foot of the bather moves by the water flow.

  ADVANTAGE OF THE INVENTION According to this invention, the bathtub apparatus which can make a bather exercise continuously can be implement | achieved.

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 apparatus according to this embodiment.

  As shown in FIG. 1, in the bathtub apparatus 1 which concerns on this embodiment, the bathtub 2 is provided. The shape of the bathtub 2 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 2a 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 2b with which the back m2 of the bather M contacts. The foot side surface 2a and the back side surface 2b face each other across the bottom surface 2c. On the foot side surface 2 a of the bathtub 2, an ejection part 3 is provided. The ejection part 3 ejects a water flow intermittently toward the inside of the bathtub 2, and the direction of this water flow is a direction from the foot side surface 2a to the back side surface 2b. For example, two ejection parts 3 are provided and arranged in the horizontal direction.

  A pump 4 is provided outside the bathtub 2 in the bathtub device 1. The water absorption side pipe of the pump 4 communicates with the inside of the bathtub 2. Thereby, the pump 4 draws water out of the bathtub 2, produces | generates a water flow, and discharges it. Furthermore, the water discharge control means 5 which supplies the water flow produced | generated by the pump 4 intermittently with respect to the ejection part 3 in the exterior of the bathtub 2 in the bathtub apparatus 1 is provided. The water discharge control means 5 is provided with a mechanism unit 5a for switching the water flow and a switching control unit 5b for controlling the operation of the mechanism unit 5a, which are interposed in the water channel between the pump 4 and the ejection unit 3. The mechanism unit 5a is a mechanical device, and the switching control unit 5b is an electronic device.

  The magnitude of the water flow ejected from the ejection part 3 is such that when the bather M brings the back m2 into contact with the back side surface 2b and the sole m1 faces the ejection part 3, the bather M's ankle a1, knee 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 2. is there. The preferred water flow size is 120 to 270 liters / minute, more preferably 150 to 250 liters / minute.

  Furthermore, a leg stabilization means 6 is provided at the foot side 2 a side in the bathtub 2. The leg stabilizing means 6 regulates the foot not to move below the path of the water flow ejected from the ejection portion 3 when the bather M makes the sole m1 face the foot side surface 2a. . Moreover, as will be described later, the stepping motion of the bather M is stepped by the water flow intermittently ejected from the ejection portion 3 so as to step on the foot. At this time, in order to induce the stepping motion to the bather M efficiently, the ejection portion 3 may be disposed at a height of, for example, 30 cm (centimeter) from the bottom surface 2c of the bathtub 2. As a result, an optimal stepping exercise is induced on the foot of the bather M. In consideration of this stepping exercise and the size of the leg of a healthy adult male, the height from the bottom surface 2c of the leg stabilizing means 6 is preferably 12 to 15 cm.

Next, the operation of this embodiment will be described.
With the water (hot water) W in the bathtub 2, the bather M enters the bathtub 2 and takes a bathing posture. The bathing posture refers to a posture in which the bather M makes the buttocks contact the bottom surface 2c of the bathtub 2, the back m2 abuts the back side surface 2b of the bathtub 2, and the sole m1 faces the foot side surface 2a. At this time, the leg stabilizing means 6 restricts the bather's feet from being lowered, and the bather M is easily positioned at a position facing the spouting portion 3 by holding the foot at a certain height or higher. Can be made. For example, the bather M causes the left and right soles to face the left and right ejection parts 3, respectively. At this time, 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 4 draws up the water in the bathtub 2 to generate a water flow and supplies it to the water discharge control means 5. Further, the switching control unit 5 a of the water discharge control device 5 controls the mechanism unit 5 b to supply water flow intermittently to the ejection unit 3. For example, the water discharge control means 5 supplies a water flow to the left and right ejection parts 3 alternately. Thereby, a water flow is alternately ejected from the right and left ejection parts 3. That is, water flow is intermittently ejected from each ejection part 3, but the phases are opposite to each other between the left and right ejection parts 3.

  When a water flow is jetted from the ejection part 3, this water flow presses the sole of the bather M. Accordingly, 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 2b. On the other hand, when the water flow is no longer ejected from the ejection portion 3, the pressure that presses the sole disappears, so that the ankle joint a1, the knee joint a2 and the hip joint a3 naturally extend, and the foot moves toward the foot side surface 2a, It returns to the vicinity of the ejection part 3. Therefore, the foot of the bather reciprocates along the longitudinal direction of the bathtub 2 by the jetting unit 3 ejecting the water flow intermittently. In addition, by alternately ejecting water flows from the left and right ejection parts 3, the left and right feet reciprocate in opposite phases, and a movement simulating walking is possible.

  At this time, since the leg stabilization means 6 restricts the downward movement of the foot, the range of motion of the foot in the vertical direction is restricted to the range R, so that the foot is unlikely to come off the water flow path. Thus, the foot reciprocates along the water flow path. That is, the leg stabilizing means 6 can guide the foot of the bather M so that it does not deviate from the path of the water flow when the foot of the bather M moves due to the water flow intermittently ejected from the ejection portion 3. That is, by the leg stabilizing means 6 along the water flow path, the water flow ejected from the ejection portion 3 can be accurately grasped by the sole even during the continuous reciprocating motion, and the stepping motion is continuously performed. be able to.

Next, the effect of this embodiment will be described.
As described above, according to the present embodiment, the ejection part 3 intermittently ejects 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 to cause the bather M to exercise. be able to. At this time, the bathing person M can be made to perform the exercise | movement imitating walk by injecting a water flow by the right and left ejection part 3 alternately. Also, the bather M is disturbed and disturbed by alternately discharging water to the right and left soles, by touching the limbs to the back side surface 2b, bottom surface 2c and foot side surface 2a of the bathtub. By taking a compensating action to stabilize the bathing posture, the muscles of the whole body are activated, but this can also be exercised. At that time, water discharge to the sole works as a direct disturbance, and the inertia and viscosity force of the hot water in the bathtub generated by the disturbed body movement works as an indirect disturbance. You can exercise your whole body more efficiently than you do.

  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.

  Furthermore, according to the present embodiment, the leg stabilizing means 6 regulates the downward movement of the foot, so that the foot is unlikely to come off the water flow path, and the reciprocating motion of the foot is stabilized. As a result, the bather does not need to use nerves to keep the foot in the water flow path, and can continue to exercise comfortably for a long time in a more relaxed state.

  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 specific example embodying the first embodiment will be described.
First, a first specific example of the first embodiment will be described.
FIG. 2 is a perspective view schematically illustrating the bathtub device according to this example.
In FIG. 2, the back side surface 2b (see FIG. 1) and one side surface of the bathtub 2 are not shown, and the pump 4 (see FIG. 1) is also not shown. The same applies to FIGS. 3 to 7 and FIGS. 9 to 11 described later.

  As shown in FIG. 2, in the bathtub apparatus 11a which concerns on this example, the nozzle 13 is provided as an ejection part. Two nozzles 13 are arranged in the horizontal direction, and the distance between them is about the distance between both feet of a person. Moreover, the overhang | projection part 16a is formed as a leg part stabilization means. The overhanging portion 16 a protrudes toward the inside of the bathtub 2 at a corner portion between the foot side surface 2 a and the bottom surface 2 c of the bathtub 2 and below the nozzle 13. The shape of the overhanging portion 16a is a quadrangular prism shape extending in the width direction of the bathtub 2, that is, in a direction orthogonal to the longitudinal direction. Accordingly, the upper surface 17a of the overhang portion 16a is flat. The position of the end on the back side 2b side of the overhanging portion 16a is the position where the bather's sole is positioned when the bather bends the ankle joint, knee joint and hip joint by the water flow sprayed from the nozzle 13 It is the back side 2b side rather than.

  In this specific example, the bather puts his / her foot on the upper surface 17a of the overhanging portion 16a so that the sole can be positioned at the same height as the nozzle 13. Further, when the water flow is jetted from the nozzle 13 and the bather's foot moves to the back side, the bather's foot is on the upper surface 17a and does not sink. Thus, when the water flow is intermittently ejected from the nozzle 13 and the foot reciprocates, the foot is restricted from moving below the upper surface 17a and is guided so that the foot does not deviate from the water flow path. Can do. Configurations, operations, and effects other than those described above in this specific example are the same as those in the first embodiment described above.

Next, a second specific example of the first embodiment will be described.
FIG. 3 is a perspective view schematically illustrating a bathtub device according to this example.
FIG. 4 is a perspective view illustrating the exercise state of the bather when the bathtub apparatus according to this example is activated. FIG. 4 shows the lower body of the bather M.

  As shown in FIG. 3, in the bathtub apparatus 11b which concerns on a specific example, compared with the above-mentioned 1st specific example, the shape of the overhang | projection part differs. That is, also in this specific example, as in the first specific example described above, an overhanging portion 16b extending in the width direction is formed below the nozzle 13 and at the corner portion of the foot side surface 2a and the bottom surface 2c. However, in the upper surface 17b of the overhanging portion 16b, a concave portion 18b is formed in a region corresponding to a region immediately below the path of the water flow ejected from the nozzle 13. That is, two concave portions 18b are formed on the upper surface 17b. Each recessed part 18b is extended along the longitudinal direction of the bathtub 2, and the shape of the cross section orthogonal to the longitudinal direction is a trapezoid shape whose upper side is wide and whose lower side is narrow. Therefore, the bottom surface of each recess 18b is a horizontal surface, and the side surface is an inclined surface. The configuration of the present example other than the above is the same as that of the first example described above.

  As shown in FIG. 4, also in this specific example, similarly to the first specific example described above, the water flow is intermittently ejected from the nozzle 13, so that the ankle joint a <b> 1, knee joint a <b> 2, and hip joint of the bather M are obtained. a3 can bend and stretch to allow the bather to make a passive movement. In this specific example, when the bather M places his / her foot on the upper surface 17b of the overhanging portion 16b, the downward movement of the bather's foot is regulated by positioning the foot within the recess 18b. At the same time, movement in the width direction is also restricted, and the foot can be more reliably positioned in the water flow path. Moreover, in this specific example, the recessed part 18b which is a trapezoidal groove | channel is formed in the overhang | projection part 16b as a leg part stabilization means, and it guides so that the water flow discharged from the nozzle 13 may go to a fixed direction. can do. Accordingly, even when the bather M is performing a stepping exercise and the sole is far from or close to the nozzle 13, the water flow is stably jetted against the bather M's sole. can do. As a result, the bather M can perform a smooth stepping exercise. The operations and effects other than those described above in this specific example are the same as those in the first specific example described above.

Next, a third specific example of the first embodiment will be described.
FIG. 5 is a perspective view schematically illustrating the bathtub device according to this example.
As shown in FIG. 5, in this specific example, the upper surface of the overhanging portion is a smooth curved surface as compared with the second specific example described above. That is, in the bathtub apparatus 11c according to this specific example, the overhang portion 16c is provided, and the upper surface 17c of the overhang portion 16c is curved along the width direction of the bathtub 2, and is ejected from the nozzle 13. A recess 18c is formed immediately below the water flow path. The upper surface 17 c is not curved along the longitudinal direction of the bathtub 2. According to this specific example, as compared with the second specific example described above, the bather's legs do not hit the corners on the upper surface of the overhanging portion, and can exercise more comfortably. Moreover, the mortar-shaped recessed part 18c does not restrict | limit the opening angle of both feet at the time of a bather making a sole face the nozzle 13 rather than the rectangular-shaped recessed part 18b shown in FIG. For this reason, the bather can take a more relaxed posture when the sole of the foot is opposed to the nozzle 13 and can perform the stepping exercise more comfortably. Configurations, operations, and effects other than those described above in the present specific example are the same as those in the second specific example described above.

Next, a fourth specific example of the first embodiment will be described.
FIG. 6 is a perspective view schematically illustrating the bathtub device according to this example.
As shown in FIG. 6, in this specific example, the shape of the recess formed on the upper surface of the overhanging portion is different from that of the second specific example described above. That is, also in the bathtub apparatus 11d according to this specific example, a recess 18d extending in the longitudinal direction of the bathtub apparatus 2 is formed on the upper surface 17d of the overhang portion 16d, as in the above-described second specific example. However, in this specific example, the depth of the recess 18d from the upper surface 17d is deeper than the depth from the upper surface 17c (see FIG. 3) of the recess 18c in the second specific example described above. Moreover, the shape of the cross section of the concave portion 18d in the longitudinal direction is a rectangle.

  According to this specific example, it is possible to more reliably prevent the bather's legs from moving in the width direction of the bathtub 2 as compared to the second specific example described above. That is, since the recess 18d shown in FIG. 6 is deeper than the recess 18c shown in FIG. 3, the adduction and abduction of the bather M's feet can be more effectively suppressed, and the stepping exercise can be more stably performed. Can be done continuously. Moreover, when not exercising, it is possible to take a bathing posture with the legs lowered. Configurations, operations, and effects other than those described above in the present specific example are the same as those in the second specific example described above.

Next, a fifth specific example of the first embodiment will be described.
FIG. 7 is a perspective view schematically illustrating the bathtub device according to this example.
As shown in FIG. 7, in this specific example, the concave portion 18e formed on the upper surface 17e of the overhang portion 16e is deeper than the fourth specific example described above. The height is equal to the height of the bottom surface 2 c of the bathtub 2. Thereby, while the movement of the bather's leg part of the width direction can be controlled more reliably, when not exercising, it is possible to take a bathing posture with the sole at the same height as the buttocks. Configurations, operations, and effects other than those described above in the present specific example are the same as in the above-described fourth specific example.

Next, a second embodiment of the present invention will be described.
FIG. 8 is a schematic view illustrating the bathtub apparatus according to this embodiment.
As shown in FIG. 8, in the present embodiment, the structure of the leg stabilizing means is different from that in the first embodiment described above. That is, in the bathtub apparatus 21 according to the present embodiment, the leg stabilizing means 26 is provided in the portion on the foot side surface 2a side in the bathtub 2, as in the first embodiment described above. The means 26 regulates that the foot moves in the width direction of the bathtub 2 when the bather M makes the sole m1 face the foot side surface 2a. Other configurations in the present embodiment are the same as those in the first embodiment.

Next, the operation of this embodiment will be described.
In this embodiment, when the bather's feet reciprocate along the longitudinal direction of the bathtub 2 due to the water flow intermittently ejected from the ejection portion 3, the leg stabilizing means 26 is used to move both feet of the bather M. Restricts movement in the width direction. This makes it difficult for the foot to come off the water flow path and stabilizes the reciprocating motion of the foot. Moreover, in order to induce the stepping motion of the whole leg part efficiently by the water flow discharged from the ejection part 3, it is necessary to transmit the force of the water flow discharged from the injection part 3 efficiently to the whole leg part. At this time, if a bather's leg part remove | deviates from the extension line of the ejection part 13, the loss of the pressing force produced | generated by a water flow will become large. Therefore, in the present embodiment, the leg stabilizing means 26 holds the entire leg portion on the extension line of the injection section 3 to thereby provide the leg stabilizing means for guiding only the foot shown in the first embodiment. In comparison, the force of the water flow can be used for the stepping motion more efficiently. 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 specific example embodying the second embodiment will be described.
First, a first specific example of the second embodiment will be described.
FIG. 9 is a perspective view schematically illustrating a bathtub device according to this example.

  As shown in FIG. 9, in the bathtub device 31 a according to this specific example, a pair of overhangs are provided on both sides of the bathtub 2 in the width direction as the leg stabilization means, which are in contact with the foot side surface 2 a of the bathtub 2. A portion 36a is formed. The overhang portions 36a are formed on both sides of the region where the two nozzles 13 are formed, and overhang so as to approach each other. For example, the overhang portions 36a are formed over the entire length of the bathtub 2 in the height direction. The position of the end on the back side 2b side of the overhanging portion 16a is the position where the bather's sole is positioned when the bather bends the ankle joint, knee joint and hip joint by the water flow sprayed from the nozzle 13 It is the back side 2b side rather than.

  In this specific example, the bather puts both feet in the space between the overhanging portions 36 a, so that the sole can be easily disposed at a position facing the nozzle 13. Also, when the water flow is jetted from the nozzle 13 and the bather's foot moves to the back side, the bather's foot is still in the overhanging portion 36a. That is, a pair of overhang | projection parts 36a restrict | limit that both the legs of the bather M are enclosed in the space between the overhang | projection parts 36a, and move to the width direction outer side. Accordingly, when the water flow is intermittently ejected from the nozzle 13 and the foot reciprocates, it is possible to guide the foot so that it does not come off the water flow path. Configurations, operations, and effects other than those described above in this specific example are the same as those in the second embodiment described above.

Next, a second specific example of the second embodiment will be described.
FIG. 10 is a perspective view schematically illustrating a bathtub device according to this example.
As shown in FIG. 10, in the bathtub apparatus 31b according to this specific example, compared to the bathtub apparatus 31a according to the first specific example described above (see FIG. 9), between the pair of overhang portions 36a, An overhang portion 36b is provided. The overhang portion 36 b is formed between the two nozzles 13 and projects toward the inside of the bathtub 2. More specifically, the overhang portion 36b is, for example, the same distance as the overhang portion 36a in the direction from the region between the nozzles 13 on the foot side surface 2a and the region formed directly above and below the region to the back side surface 2b. It is extended. Thus, gaps 37a are formed between the one overhanging portion 36a and the overhanging portion 36b and between the other overhanging portion 36a and the overhanging portion 36b, respectively. The configuration other than the above in this specific example is the same as that of the first specific example of the second embodiment described above.

  According to this specific example, the bather takes a bathing posture and makes both feet enter the gap 37 a, so that the sole can be easily disposed at a position facing the nozzle 13. Moreover, it can control about each of both feet that a bather's both feet move to the width direction of a bathtub. That is, it is possible to restrict the bather's left foot from moving to the right side of the left water flow path and the right foot from moving to the left side from the right water flow path. Thereby, it can prevent that a bather's both legs are entangled, can make a motion of a foot more stable, and can be exercised more comfortably by a bather. Operations and effects other than those described above in this specific example are the same as those in the first specific example of the second embodiment described above.

Next, a third specific example of the second embodiment will be described.
FIG. 11 is a perspective view schematically illustrating a bathtub device according to this example.
As shown in FIG. 11, this specific example is a specific example in which the first embodiment and the second embodiment described above are combined. That is, in the bathtub apparatus 31 c according to this specific example, the overhanging portion 36 c is formed on the foot side surface 2 a of the bathtub 2, and the overhanging portion 36 c is disposed below and on the side of the nozzle 13. Specifically, the shape of the overhanging portion 36c is E-shaped when viewed from the back side surface 2b (see FIG. 8), so that the path of water flow ejected from the nozzle 13 and the region immediately above it are exposed. Two gaps 37b having openings on the upper side and the back side are formed.

  According to this specific example, the bather takes a bathing posture and places both feet in the gap 37b, whereby the sole can be easily disposed at a position facing the nozzle 13. Further, even when the foot is reciprocating, the foot is restricted from deviating downward and laterally from the water flow path, so that the motion of the foot can be further stabilized. Configurations, operations, and effects other than those described above in this specific example are the same as those in the second specific example of the second embodiment described above.

  In the first to third specific examples of the second embodiment described above, the example in which the overhanging portion is formed over the entire length in the height direction of the bathtub is shown, but the second embodiment is based on this. It does not limit, The overhang | projection part should just be formed in the side of the nozzle at least.
