Description

  The present invention relates to a bathtub apparatus and a bathroom massage apparatus, and more particularly, to a bathtub apparatus and a bathroom massage apparatus that can massage a bather.

  In recent years, bathroom massage devices that massage bathers in a bathtub have been developed. For example, Patent Document 1 discloses a bathroom massage apparatus installed in a bathtub, a back frame supported to be swingable with respect to a side wall of the bathroom, a seat frame connected to the back frame, There is disclosed a bathroom massage device comprising a lower limb frame connected to the seat frame, and a massage bag attached to each frame. Patent Document 1 discloses that the angle of the backrest frame is adjusted to hang down along the side surface of the bathtub so as to reach the vicinity of the bottom surface of the bathtub.

  However, the technique described in Patent Document 1 has the following problems. That is, in the bathroom massage apparatus described in Patent Document 1, the backrest frame is supported so as to be swingable with respect to the side surface of the bathroom, but the backrest frame is simply suspended along the side surface of the bathtub. For this reason, the shape of the entire bathroom massage apparatus is uniquely determined by the shape of the bathtub. For this reason, when a bather sits on this massage apparatus for bathrooms, the posture of the bather is determined to be one posture, and even when massaged in this state, only the same sense of stimulation can be received. For this reason, with the technique described in Patent Document 1, the effect of massage is insufficient.

A headrest 4 is provided around the fixed support portion 3 so as to cover the fixed support portion 3. The headrest 4 has waterproofness and cushioning properties, supports the back head of the bather M, and is configured integrally with the fixed support portion 3. For example, the shape of the headrest 4 is a substantially cylindrical shape, and its central axis extends in the left-right direction of the bathtub 2, and the fixed support portion 3 is disposed on this central axis portion. The shape of the fixed support portion 3 is a substantially cylindrical shape, and the central axis extends in the left-right direction of the bathtub 2. Then, both end portions of the fixed support portion 3 protrude from both end portions of the headrest 4, and the protruding portions are connected to the rim 2 f of the bathtub 2. Thereby, the fixed support portion 3 and the headrest 4 are fixed to the rim 2 f of the bathtub 2.

  A backrest frame 5 is drawn out from both ends of the fixed support portion 3. The backrest frame 5 is formed by a single pipe, and has a substantially U-shaped shape. Both ends of the backrest frame 5 are rotatably connected to both ends of the fixed support portion 3. The backrest frame 5 can be fixed to the fixed support portion 3 at two different angles. Hereinafter, of the two angles to which the back frame 5 is fixed, the angle at which the back frame 5 becomes closer to the vertical is referred to as a “sitting position angle”, and the angle at which the back frame 5 becomes closer to the horizontal is referred to as a “suppression angle”. 1 and 2 show a case where the angle of the back frame 5 is set as a sitting position angle. The sitting angle and the supine angle are preferably in the range of about 110 degrees to about 150 degrees with respect to the horizontal plane.

  Hereinafter, the configuration of the backrest frame 5 will be described in more detail. The backrest frame 5 is composed of a total of nine substantially linear portions including a pair of portions 5a, a pair of portions 5b, a pair of portions 5c, a pair of portions 5d, and a single portion 5e in order from both ends. It is composed of The portion 5 a extends from the end portion of the fixed support portion 3 along the central axis of the fixed support portion 3 in a direction away from the fixed support portion 3. The boundary part between the part 5a and the part 5b is bent at a substantially right angle, and when the angle of the backrest frame 5 is the sitting position angle, the part 5b extends substantially horizontally in the direction toward the foot side of the bathtub 2. The boundary portion between the portion 5b and the portion 5c is bent at an obtuse angle, and the portion 5c extends substantially parallel to the inclined surface 2b downward. The boundary between the part 5c and the part 5d is bent at a substantially right angle, and the part 5d extends in a direction toward the inclined surface 2b. The portion 5 e is a portion that connects the pair of portions 5 d and extends parallel to the central axis of the fixed support portion 3.

  Two base plates 6 are provided between the pair of portions 5 c in the back frame 5. The shape of the base plate 6 is substantially rectangular, the longitudinal direction thereof is parallel to the central axis of the fixed support portion 3, and both longitudinal ends thereof are connected to the portion 5 c of the backrest frame 5. The position of the base plate 6 is a position corresponding to, for example, the waist and the shoulder rib periphery of the bather M when the bather M takes a bathing posture.

  Each base plate 6 is provided with two advancing portions 7 arranged in the horizontal direction. That is, in the bathroom massage apparatus 1, a total of four advancing portions 7 are arranged in a matrix of 2 rows and 2 columns, and are attached to the backrest frame 5 via the base plate 6. The advancing portion 7 has a state in which the surface thereof is substantially flush with the surface of the base plate 6 (hereinafter referred to as “standard state”) and a state in which the advancing portion 7 has advanced in a direction away from the backrest frame 5 and the base plate 6 (hereinafter referred to as “standard state”). , And called “advanced state”). And the advance direction of each advance part 7 is a direction perpendicular | vertical with respect to the surface of the baseplate 6, for example. Further, the amount of advancement of the two lower advancing portions 7 is larger than the amount of advancement of the two upper advancing portions 7.

  In addition, the bathroom massage apparatus 1 is provided with driving means 8 for driving the advancement section 7. The driving means 8 is disposed outside the bathtub 2 and is connected to the advancing portion 7 through the fixed support portion 3, the backrest frame 5 and the base plate 6.

Next, the operation of the bathtub apparatus and bathroom massage apparatus according to this embodiment configured as described above will be described.
First, the operation when the angle of the backrest frame 5 is set as the sitting angle will be described.
FIG. 3 is a perspective cross-sectional view illustrating the bathtub device according to the present embodiment, in which the angle of the backrest frame is a sitting position angle, the upper advancement portion is in a standard state, and the lower advancement portion is in an advancement state. Show the case
FIG. 4 is a perspective cross-sectional view illustrating the bathtub device according to the present embodiment, in which the angle of the backrest frame is the sitting position, the upper advancement portion is in the advanced state, and the lower advancement portion is in the standard state. Show the case.
1 and 2 show a case where the angle of the backrest frame is the sitting position angle and all the advanced parts are in the standard state.

  First, as shown in FIG.1 and FIG.2, let the angle of the backrest frame 5 be a seating-position angle. At this time, the portion 5e of the backrest frame 5 abuts on the inclined surface 2b of the bathtub 2, and further rotation is restricted. Further, the direction in which the portion 5c extends is substantially parallel to the inclined surface 2b, and therefore the surface of the base plate 6 is substantially parallel to the inclined surface 2b. In this state, hot water (not shown) is stored in the bathtub 2, and the bather M enters the bathtub 2. Then, put the buttocks on the bottom surface 2a, lean the back on the base plate 6, and put the foot on the horizontal surface 2d to take a bathing posture. At this time, the posture of the bather M is the sitting posture. That is, since the bather takes a posture in which the body is raised, the back of the head is separated from the headrest 4. Thus, when the bather M takes a sitting posture, the muscles of the back stretch. The head, neck and shoulders are located outside the hot water W, and the weight of these parts is supported mainly by the area in contact with the bottom surface 2a of the buttocks. And the surface of the advance part 7 is located in the position corresponded to the bather's M waist | hip | lumbar part and a shoulder rib periphery.

  In this state, as shown in FIG. 3, the driving means 8 brings the lower advancing portion 7 into the advancing state. That is, the surface of the advancing portion 7 is protruded from the surface of the base plate 6. Thereby, the waist part of the bather M is pressed by the lower advancing part 7. Moreover, as shown in FIG. 4, the drive means 8 makes the upper advancing part 7 into an advancing state. Thereby, the shoulder rib periphery of the bather M is pressed by the upper advancing part 7. At this time, the bather M is in the sitting position and the back muscles are stretched, so that the advancing section 7 can massage the back muscles strongly. At this time, since the weight of the bather M's water surface, that is, the weight of the head, neck and shoulders, is applied to the buttocks of the bather M, the buttocks float from the bottom surface 2a. There is no.

Next, the operation when the angle of the backrest frame 5 is set to the supine angle will be described.
FIG. 5 is a perspective cross-sectional view illustrating the bathtub device according to the present embodiment, and shows a case where the angle of the backrest frame is a supine angle and all the advancing portions are in a standard state,
FIG. 6 is a sectional view thereof.
FIG. 7 is a cross-sectional view illustrating the bathtub device according to the present embodiment, and shows a case where the angle of the backrest frame is the supine angle and all the advancing portions are in the advancing state.

  As shown in FIGS. 5 and 6, the backrest frame 5 is rotated with respect to the fixed support portion 3, and the angle is set as the supine angle. At this time, the portion 5e of the back frame 5 is separated from the inclined surface 2b of the bathtub 2, and the direction in which the portion 5c extends is closer to the horizontal than the inclined surface 2b. Therefore, the surface of the base plate 6 is also more horizontal than the inclined surface 2b. Close to. Then, the bather M enters the bathtub 2, puts the buttocks on the bottom surface 2a, leans the back on the base plate 6, presses the back of the head against the headrest 4, puts the foot on the horizontal surface 2d, and takes a bathing posture. At this time, the posture of the bather M is a supine posture. When the bather M takes a supine posture, the back muscles relax. Also, the bather's head, neck and shoulders are located outside the hot water W, and the weight of these portions is supported mainly by the area of the back in contact with the base plate 6. And the surface of the advance part 7 is located in the position corresponded to the bather's M waist | hip | lumbar part and a shoulder rib periphery.

  In this state, when the driving means 8 sets the lower advancing portion 7 to the advancing state, the lower advancing portion 7 presses the waist of the bather M. Further, when the driving means 8 sets the upper advancement portion 7 to the advancement state, the upper advancement portion 7 presses the shoulder rib periphery of the bather M. At this time, since the bather M is in the supine posture and the muscles of the back are relaxed, the advancement unit 7 mainly pushes the spine of the bather M. Thereby, it is possible to give the bather M a feeling of pressing when the muscles of the back are relaxed and a feeling of stretching that opens the body to both sides.

  Further, only the lower advancing part 7 is set to the advanced state, or all the advanced parts 7 are set to the advanced state as shown in FIG. 7, and the advancing amount of the lower advancing part 7 is set to the advancing amount of the upper advancing part 7. By making it larger than this, the waist part of the bather M is lifted obliquely upward. As a result, the bather M's buttocks are separated from the bottom surface 2a and float in water. As a result, the weights of the part of the bather M coming out from the water surface, that is, the head, neck and shoulders, are mainly applied to the region of the back of the bather M in contact with the advancing part 7. For this reason, the massage effect and the stretch effect by the advance part 7 increase. At this time, since the buttocks of the bather M are free to float from the bottom surface 2a, the upper body of the bather M is stretched in the vertical direction. As a result, the bather M can be given a stretch feeling in the vertical direction. Furthermore, at this time, since it becomes a floating bath in which the buttocks float, it is possible to promote blood circulation in the vicinity of the buttocks together with the thermal effect by bathing.

Next, the effect of this embodiment will be described.
According to the bathtub device according to the present embodiment, the posture of the bather M can be changed by changing the angle of the backrest frame 5 with respect to the fixed support portion 3. And in each attitude | position, the advancing part 7 is driven and massage can be given to the bather M with a different sensory stimulus. In the present embodiment, for example, as described above, the angle of the backrest frame 5 is set to be substantially parallel to the inclined surface 2b of the bathtub 2 (sitting angle), and each time it is closer to the horizontal than the inclined surface 2b (elevation) Angle). Thereby, when the angle of the backrest frame 5 is fixed at the sitting position, the posture of the bather becomes a sitting position, and a feeling of pressing in a state where the muscles of the back are stretched can be given. As a result, a strong massage feeling can be given. On the other hand, when the angle of the backrest frame 5 is fixed at the supine angle, the bather's posture is a supine posture, a feeling of pressing with the muscles of the back relaxed, and a feeling of stretch that stretches the body to both sides and up and down And can give. That is, a stretch feeling can be mainly given.

  Thus, according to the present embodiment, the posture of the massage can be changed by changing the posture, so that the posture does not become cramped even if the bather takes a bath for a long time, and the same posture or press When the user gets tired of feeling, the posture and the feeling of pressing can be changed according to preference. Thereby, the massage effect can be improved.

  Further, if the angle of the backrest frame 5 is set to the supine angle, the bather M is in a supine posture, so that the bather M can be relaxed mentally and physically. And a massage and a stretch can be received with a relaxed supine posture. Thereby, a massage effect and a stretch effect can be improved further.

  Further, in the present embodiment, the amount of advancement of the lower advancement portion is made larger than the advancement amount of the upper advancement portion, so that the upper advancement portion performs massage around the shoulder ribs and bathes in the supine posture. A person's buttocks can be lifted and a stretch effect can be obtained.

  Furthermore, in the present embodiment, since the headrest is provided integrally with the fixed support portion around the fixed support portion, the headrest and the fixed support portion can be configured in a compact manner, and the appearance is clean. Moreover, since the fixed support part is being fixed to the rim of the bathtub, the construction etc. for attaching a fixed support part to the side wall of a bathroom are unnecessary. Furthermore, the bathroom massage device can be retrofitted to the bathtub simply by adding a simple process to the bathtub. Further, the backrest frame can be removed from the fixed support portion later, and only the headrest can be used. On the other hand, if it is attempted to fix the fixed support part to the side wall of the bathroom, a side wall reinforcing work or the like is required in addition to the fixing support part installation work, and the cost increases and the installation property is poor. Moreover, it becomes impossible to freely select the shape and installation position of the bathtub.

  Furthermore, in this embodiment, since the fixed support part is fixed to the rim of the bathtub and the headrest is formed so as to cover the fixed support part, the backrest frame can be rotated around the headrest. . Thus, when the bather is in a supine posture and the head is leaning against the headrest, the chest cavity can be expanded by pressing the back with the bather's head as a fulcrum. As a result, it can be expected to increase the breathing volume of the bather, and when the breathing volume increases, the oxygen intake increases, and accordingly, effects such as fatigue recovery and relaxation can be expected. Conventionally, during bathing, water pressure is applied to the chest and the amount of breathing is reduced, so it is not so relaxing, and in order to avoid this, there is a case where bathing in a half-body bath is forced. However, according to the present embodiment, the bather can be stretched to widen the chest cavity, so that the bather can relax while staying in hot water up to the chest like a normal bath. On the other hand, when the bather is in the sitting position, the load on the head is applied to the buttocks and the pressing portion, so that the pressing feeling can be enhanced and effective massage can be performed.

Next, a second embodiment of the present invention will be described.
FIG. 8 is a perspective cross-sectional view illustrating the bathtub device according to this embodiment, and shows a case where the angle of the backrest frame is a retraction angle,
FIG. 9 is a sectional view thereof.

  As shown in FIGS. 8 and 9, in the bathtub device 21 according to the present embodiment, the backrest frame 5 further rotates beyond the supine angle, and the backrest frame 5 is angled so that the backrest frame 5 faces upward. That is, the backrest frame 5 can be fixed at an angle at which the portion 5e of the backrest frame 5 is positioned above the portion 5a (hereinafter referred to as “retraction angle”). Accordingly, the entire backrest frame 5 is held above the bathtub 2. Other configurations in the present embodiment are the same as those in the first embodiment. That is, the angle of the backrest frame 5 can be fixed not only at the retract angle but also at the sitting position and the supine angle.

  In the present embodiment, by setting the angle of the backrest frame 5 as the retraction angle, the backrest frame 5 can be retracted above the bathtub 2 together with the base plate 6 and the advancing portion 7. Thereby, for example, when the bathroom massage apparatus 1 is not used, the backrest frame 5 can be stored above the rim 2f along the bathroom side wall (not shown). As a result, for example, when the bather performs normal bathing without using the bathroom massage apparatus 1, the inside of the bathtub 2 can be widely used. At this time, since the headrest 4 remains on the rim 2f, the bather can use the headrest 4 even when the bathroom massage apparatus 1 is not used. Further, the backrest frame 5 does not get in the way when the bathtub 2 is cleaned. 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 third embodiment of the present invention will be described.
FIG. 10 is a perspective cross-sectional view illustrating the bathtub device according to this embodiment.
As shown in FIG. 10, in the bathtub device 31 according to the present embodiment, the two base plates 6 move independently from each other with respect to the backrest frame 5 within the region where the portion 5 c is extended. Can do. That is, each base plate 6 is slidable along the longitudinal direction of the portion 5 c of the backrest frame 5. Thereby, the distance between the fixed support part 3 and the advancing part 7 can be adjusted, and the position of the advancing part 7 can be adjusted according to the site | part which wants to receive a bather's physique, a massage, etc. Other configurations, operations, and effects of the present embodiment are the same as those of the first embodiment.

Next, a fourth embodiment of the present invention will be described.
FIG. 11 is a perspective cross-sectional view illustrating the bathtub device according to the present embodiment, showing a state in which the backrest frame is contracted,
FIG. 12 is a perspective cross-sectional view illustrating this bathtub device, showing a state in which the backrest frame is extended,
FIG. 13: is sectional drawing which illustrates this bathtub apparatus, and shows the state which the backrest frame is extended.

  As shown in FIG. 11 thru | or FIG. 13, compared with the bathtub apparatus 11 (refer FIG. 1) which concerns on the bathtub apparatus 11 which concerns on 1st Embodiment mentioned above, the bathtub apparatus 41 which concerns on this embodiment differs in the structure of the backrest frame 45. FIG. Yes. The backrest frame 45 in the present embodiment includes two (one pair) frames 45a and one frame 45b. Each frame 45a corresponds to a portion made up of one portion 5a, 5b and 5c (see FIG. 1) in the back frame 5 of the first embodiment, and is pivotally supported by the fixed support portion 3. Yes. The frame 45b corresponds to a portion composed of the two portions 5c, the two portions 5d, and the one portion 5e in the backrest frame 5 of the first embodiment, and holds the base plate 6 and the advancing portion 7. Yes. The inner diameter of the frame 45b is slightly larger than the outer diameter of the frame 45a, and the portion corresponding to the portion 5c of the frame 45b is slidably fitted into the portion corresponding to the portion 5c of the frame 45a. Therefore, the frame 45b can slide with respect to the frame 45a, whereby the backrest frame 45 is made extendable.

  In this embodiment, as shown in FIG. 11, if the frame 45b is fixed to the frame 45a at a position close to the fixed support portion 3, the backrest frame 45 can be contracted, and the advancement portion 7 is relatively high. Can be held in position. On the other hand, as shown in FIGS. 12 and 13, if the frame 45 b is fixed at a position far from the fixing support portion 3, the backrest frame 45 can be extended, and the advancing portion 7 can be held at a relatively low position. it can. Thus, according to this embodiment, by adjusting the length of the backrest frame 45, the distance between the fixed support part 3 and the advancing part 7 is adjusted, and the position of the advancing part 7 is adjusted to the physique of the bather. And it can be adjusted according to the part you want to receive massage. Other configurations, operations, and effects of the present embodiment are the same as those of the first embodiment.

  In each of the above-described embodiments, the bathroom massage device may be detachable from the bathtub. Thereby, while being able to attach the massage apparatus for bathrooms to a normal bathtub, when it stops using the massage apparatus for bathrooms, it can remove from a bathtub. In this case, a fixing means for fixing the bathroom massage device to the bathtub is provided on the fixing support portion of the bathroom massage device. For example, a suction cup can be used as the fixing means.

  Further, the above-described embodiments can be combined with each other. For example, in a bathtub apparatus in which a backrest frame is extendable like the bathtub apparatus according to the fourth embodiment, the base plate may be movable with respect to the backrest frame as in the third embodiment. Thereby, each base plate can be moved independently of each other within a large range of motion. In this bathtub device, as shown in the second embodiment, the backrest frame may be retractable above the bathtub.

  Further, in each of the above-described embodiments, only one base plate may be provided. In other words, the advancing portion may have a single stage configuration. Furthermore, only one advancing portion may be provided in each base plate, or three or more may be provided. Furthermore, the advance direction of the lower advance portion may be inclined upward with respect to the direction perpendicular to the base plate. Thereby, the recessed part of the S-shaped curve part in a bather's waist | hip | lumbar part can be pressed substantially perpendicularly by this lower advancing part, and the massage effect and the stretch effect can be improved more. Furthermore, three base plates may be provided, and the advancing portion may have a three-stage configuration. Thereby, for example, a waist part of a bather, a shoulder rib circumference, and a shoulder can be massaged simultaneously. At this time, the advancing direction of the upper advancing portion that presses the shoulder may be inclined downward with respect to the direction perpendicular to the surface of the base plate. Thereby, a bather's shoulder can be pressed from upper direction by this upper advancing part, and the massage effect by shoulder massage can be increased further.

  Furthermore, the headrest may be provided separately from the fixed support portion. Moreover, the headrest does not need to be provided. In this case, when the bather takes a supine posture, the back of the head may be supported by a rim of the bathtub or the like. Furthermore, the angle of the backrest frame may be fixed at one or more angles as necessary in addition to the above-mentioned sitting angle, supine angle, and retracted angle. For example, the sitting angle and the supine angle may be set at a plurality of levels, and the most comfortable angle may be selected according to the physique and preference of the bather.
