Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bathtub formed by integral molding using FRP or the like.
[0002]
[Prior art]
Various types of conventional bathtubs have been developed and used, for example, plastic resin integrally formed with FRP or the like, or metal made of stainless steel or the like.
[0003]
In addition, in such a bathtub, for example, a part provided with a stool that is formed higher on a part of the bottom surface has been developed, and a half-body bath that sits on a shallow stool surface and warms from the waist down can be performed It is like that. Also, using this stool, even a small child can take a bath safely.
[0004]
[Problems to be solved by the invention]
However, in such a type of bathtub, an edge where the standing surface and the seating surface, which rises almost vertically from the bottom surface, forms a substantially right-angled edge, for example, a bather for half-body bathing. If you sit on the stool surface, the back side of the thigh may come into contact with the edge part, and you may feel pain, impairing comfort.
[0005]
In addition, when hot water is poured so that the water surface is lower than the seating surface, water tends to accumulate on the seating surface, resulting in the risk of slipping when seated and also causing problems such as water splashing. ing.
[0006]
Furthermore, in order to maintain a lying position while taking a bath, or to stand up from a lying position and get up from the lying side, if a grip or handrail is retrofitted on the side of the bathtub or the wall adjacent to the bathtub, the parts cost will be high. It may be difficult to harmonize with the design and may be uncomfortable. Also, the grips and handrails often jump out to the outside, and there is a risk that the bather will accidentally catch the limbs.
[0007]
Also, if you want to relax and immerse yourself in hot water, you will be fully satisfied as you will lie down on your body and try to extend your spine by tilting your neck and head backwards, as there is nothing to support your neck and head. In many cases, you cannot feel relaxed.
[0008]
Therefore, in view of the above-mentioned drawbacks, the present invention aims to improve the feeling of use and safety when sitting on a seating surface, and to keep the body posture during bathing and a clue when standing up. The object of the present invention is to provide a bathtub that is provided with ease of use and can provide a high level of relaxation.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a bathtub according to the present invention. In this bathtub, a seating surface 3 that is one step higher than the bottom surface 2 of the bathtub body 1 is partially formed on the bottom surface 2 side, and intersects with the seating surface 3. The bathtub side surfaces 5 and 6 substantially orthogonal to the bathtub side surface 4 are provided with armrest-like projections 51 and 61 (see FIG. 2 for the projection 61 on the bathtub side surface 6 side) and grip-like projections 52 and 62 ( As for the projection part 62 by the side of the bathtub side surface 6, see FIG. Furthermore, in this bathtub, a pillow-like protrusion 8 is formed on the upper part of the bathtub side 7 facing the bathtub side 4.
[001 1 ]
In the bottom surface 2 shown in FIG. 2, a drain outlet 21 is formed at the lowest position, and a large number of protrusions 22 having a substantially circular shape are formed over almost the entire bottom surface 2. It prevents slipping and falling when it is hung. Note that the non-slip processing of the bottom surface 2 is not particularly limited to this protrusion, and appropriate processing such as embossing the surface of the bottom surface itself or increasing the frictional resistance can be applied.
[001 2 ]
The seating surface 3 is provided with a slope (hereinafter referred to as a drainage gradient) so as to be lowered toward the bathtub side surface 4, and corner portions in three directions (three sides) of the seating surface 3 in contact with the bathtub side surface 4 Is formed with a substantially U-shaped drainage groove 31. Furthermore, the edge where the seating surface 3 and the standing wall 9 that rises from the bottom surface 2 and reaches the seating surface 3 intersects with the back of the thigh of the sitting bather, so that there is no discomfort or pain. Thus, a pair of left and right portions (chamfered portions) 32 chamfered in a state close to the shape of the back of the thigh are formed. In addition to the chamfered portion, for example, a curved shape may be used.
[001 3 ]
The armrest-like projection 51 protrudes slightly inward (inside the bathtub) in the horizontal direction by a specific height from the bottom surface 2 on the bathtub side surface 5 and lies on its back (with the back against the bathtub side surface 7). In order to maintain a posture in which the bather during bathing tilts the upper body, the elbow and hands can be hung. The armrest-shaped protrusion 61 is also formed symmetrically with the protrusion 51 and protrudes inward (inside the bathtub) from the bottom surface 2 by a specific height on the bathtub side 6.
[001 4 ]
Further, the grip-like protrusion 52 serves as a clue to support the body when a bather standing or standing while standing in the bath tub or bathing, and has a substantially chevron-shaped chevron shape and has a bottom surface on the bathtub side surface 5. 2 protrudes inwardly (in the bathtub) by substantially the same amount as the protrusion 51. Further, as shown in FIG. 3, the shape of the protrusion 52 corresponds to the direction when the bather bathes or lies, and the mountain-shaped slope 52A faces the seating surface 3 (in the foot direction during bathing). The slope 52B on the opposite side has a gentle slope, which makes it easier for a bather in a lying position to get up by grabbing the protrusion 52 by hand. The shape of the grip-like protrusion is not limited to this shape, for example, and may be any shape as long as it is easily gripped by hand.
[00 15 ]
Further, the protrusion 52 of this embodiment is continuous and integrated with the protrusion 51 (molded integrally with the bathtub). However, the protrusions 52 can be separated and separated without particularly connecting both protrusions. Good. The grip-like protrusion 62 is also formed symmetrically with the protrusion 61 and protrudes inward (in the bathtub) from the bathtub side 6 by the same amount. However, as shown in FIG. The upper side of the outer wall surface of the bathtub bulges by the protruding amount of the protrusions 51, 52 and 61, 62 (the lower side of the outer wall surface of the bathtub is depressed).
[00 16 ]
The pillow-like protrusion 8 supports the head and neck of a lying bather, and is integrated with the bathtub body 1 at the upper part of the opposite bathtub side face 7 facing and facing the bathtub side face 4 provided with the seating surface. It is shaped so that the bather in the hot water can lean on the neck or head backward while lying down. Further, as shown in FIG. 3, the inclination angle of the inner surface 81 that supports the neck and head of the protrusion 8 is formed at an angle θ2 (however, θ1> θ2) that is gentler than the inclination angle θ1 of the bathtub side surface 7. This is preferable because the feeling of relaxation is further enhanced.
In addition, as shown in FIG. 5, if the horizontal part 71 is provided in the upper part of the bathtub side surface 7 which has protruded the protrusion part 8, and the edge part of a bathtub lid is locked to this horizontal part 71, a bathtub will be shown. It is possible to prevent the hot water from cooling by keeping the inside sealing.
[00 17 ]
Moreover, the bathtub side surface 7 provided with a pillow-like protrusion 8 on the upper side allows the bather to relax by stretching the spine, that is, as shown in FIG. It has a convex part 72 whose shape is inclined and curved convexly. That is, an edge-like protrusion is formed by changing the inclination according to the level position where the protrusions 51 and 52 are formed (a shape where the lower part is a steep slope and the upper part is a gentle slope). In addition, as the convex shape of this bathtub side surface 7, you may form in a convex surface as a whole, and what formed it combining several divided planes in convex shape.
[00 18 ]
Therefore, according to this embodiment, in addition to using the seating surface 3 as a half-body bath, when a small child or an elderly person enters the bathtub, for example, the user sits on the seating surface 3 first and uses it instead of a step. However, since the drainage gradient and drainage groove 31 effectively drain the water (a structure in which water does not easily accumulate on the seating surface 3), there is little risk of slipping the foot, which is convenient in terms of safety. Good. Further, even when sitting for half-body bathing, it is possible to prevent the seat from sliding down from the seating surface 3 to the bottom surface 2.
[00 19 ]
【The invention's effect】
As described above, according to the present invention, it is composed of an integrally formed bathtub in which a seating surface that is one step higher than the bottom surface is provided on a part of the bottom surface. It is possible to warm the lower body, and it is possible to use it as a step if a small child or an elderly person puts his / her foot on the stool and enters the bathtub, and a highly safe bathtub is provided so that even a child, elderly person or disabled person can take a bath alone it can.
[002 0 ]
Moreover, according to the present invention, a pair of chamfered portions chamfered in a state close to the shape of the back surface of the thigh is formed on the edge where the standing wall surface extending from the bottom surface to the seating surface and the seating surface are in contact, and the seating surface is formed. On the edge where the stool surface and the bathtub side are in contact with each other so as to form a drainage slope that is slanted toward the side of the bathtub and drain the hot water flowing toward the side of the bathtub with the drainage slope toward the drain outlet provided on the bottom Since the drainage groove is provided, a comfortable half-body bathing that does not cause discomfort such as pain and poor usability when the back of the thighs of the bather sitting on the seating surface comes in contact with the seating surface, and the drainage performance is enhanced. Since water does not collect in the water, it is possible to avoid the danger of slipping when the user sits on the stool or slipping down when sitting. In addition, the posture during bathing can be performed without causing pain or discomfort to the feet even if the bather puts his feet on (holds) and stands on the standing wall that connects the seating surface and the bottom surface. Even when a bather with a small body takes a bath in a large bathtub, this operation can be performed and the safety of the bather can be ensured.
[002 1 ]
Further, according to the present invention, the armrest-shaped protrusions for holding a recumbent posture over the hand during bathing in lying state, a hill-shaped shape to the cue for supporting the body when rising from a lying state Because the shape of the tub has a grip-shaped protrusion on the side of the bathtub that protrudes inward from the bottom by the same amount as the protrusion on the side of the bathtub, bathing in either direction for half-body bathing or whole body bathing However, by grasping these protrusions by hand or supporting them with arms, the posture at the time of bathing can be reliably held, and not only the safety can be improved, but also a relaxed feeling of relaxation can be brought about. Moreover, since these protrusions are integrally formed on the side surface of the bathtub, the manufacturing cost can be reduced, the appearance is good, and the design is enhanced. In addition, since the protruding portion does not protrude so much as compared to a conventional handrail-type handrail, it is possible to prevent an accident such as a fall by catching a foot or a hand.
[002 2 ]
In addition, according to the present invention, a pillow-like protrusion for allowing a bather during bathing to lean on the neck or head backward on the opposite side of the bathtub side facing and facing the side of the bathtub provided with a seating surface Since the body is integrally molded, the neck and head can freely and naturally lean against the protrusions (fall back) while the body is lying on the side, so great relaxation can be obtained.
[002 3 ]
Further, according to the present invention, in the bathtub side surface on the side having the pillow-shaped protrusion, the shape in the vertical direction from the bottom surface to the upper portion is formed into a convex portion that is inclined or curved in a convex shape toward the inside of the bathtub. because there, together with the pillow-like projections, such as relaxed posture extending the back comes to take a large relaxed feeling is obtained more.
