Description

  The present invention relates to a bathtub with a handrail.

In recent years, bathtubs that can enjoy bathing more safely by providing a grip bar on the bathroom wall surface have become widespread as a response to an aging society. There is also known a bathtub in which a grip bar is provided on the bathtub wall instead of the bathroom wall. (For example, see Patent Document 1)
In a bathtub with a handrail made of such a grip bar, not only for bathers who do not need a handrail, but also for bathers who need a handrail, a hand made of a grip bar when not using a handrail. Disadvantages are that sliding is obstructing and part of the body such as limbs, towels, bathing equipment, etc. get caught in the gap between the bathtub and the gripping bar and get caught.

Accordingly, a bathtub has been developed in which the inner surface and the outer surface near the upper end of the bathtub wall are recessed to form a constricted portion, and the upper portion of the constricted portion is used as a grip portion. (For example, see Patent Document 2)
In a bathtub with a handrail provided with such a grip portion, the grip portion is gripped in the same manner as the grip bar described above. The grip bar could not be gripped firmly, and the function as a handrail was not fully fulfilled.

  The present invention has been made in view of the above points, and the object of the present invention is to provide a bather with a weak grip force, such as a handrail made of a grip portion such as a grip bar, to firmly hold the grip portion. An object of the present invention is to provide a bathtub with a handrail that cannot be gripped and does not sufficiently function as a handrail.

  In order to solve the above-mentioned problems, in the invention according to claim 1, a part of the inner surface of the bathtub 1 is recessed to form a recessed part 2 as a handrail, and the lower end of the recessed part 2 is substantially omitted. It is characterized by comprising a handle surface 3 on which a human hand can be placed facing upward.

  By adopting such a configuration, even when the bather has a weak gripping force, when standing up in the bathtub 1, it is not necessary to hold the grip part or the grip bar firmly to put on the weight, and the hand is placed on the handle surface 3. Thus, the weight can be applied, and the function as a handrail is sufficiently fulfilled.

  Moreover, in the invention which concerns on Claim 2, in the invention which concerns on Claim 1, it forms the dent part 2 as a handrail in the inner surface of the bathtub 1 over the perimeter, It is characterized by the above-mentioned. is there.

  By adopting such a configuration, it is possible to place a hand on the handle surface 3 of the recessed portion 2 at any position on the entire circumference, improving usability.

  In the invention according to claim 3, in the invention according to claim 1 or 2, the recessed portion 2 is an upper recessed portion 2 a and the lower portion of the upper recessed portion 2 a is recessed. A concave portion 2b on the side is formed, and a convex portion between the upper concave portion 2a and the lower concave portion 2b is formed as a grip portion 4.

  By adopting such a configuration, it is possible to place the hand on the handle surface 3 of the upper concave portion 2a and insert the fingertip into the lower concave portion 2b so as to grasp the grip portion 4, thereby further stabilizing. It can be a handrail.

  In the present invention, a handrail is formed as a handgrip surface on which a part of the inner surface of the bathtub is recessed to form a recessed portion, and the lower end portion of the recessed portion faces substantially upward, and a human hand can be placed thereon. With this configuration, even if you are a bather with weak grip, when you stand up in the bathtub, you do not need to hold the grip part or grip bar firmly and put your weight on it. Thus, it becomes possible to stand up easily, and the function as a handrail is sufficiently fulfilled.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The bathtub 1 is formed of, for example, a synthetic resin such as FRP or other material, and is placed on a floor pan. Although not shown, the floor pan may be a floor pan provided separately with a bathtub floor pan and a washing floor floor pan, or an integrated floor pan including a bathtub installation section and a washing section, and is not particularly limited. Moreover, what is called a half floor pan which has only a wash floor floor pan may be sufficient, and in this case, it is mounted on the floor slab of the bathroom. Moreover, the bathtub 1 and the floor pan may be integrally formed, and are not particularly limited.

  The bathtub 1 is not particularly limited as long as it has a concave portion that opens upward in which bath water accumulates. The shape of the flange portion 11 of the bathtub 1 is generally rectangular in shape in plan view. However, it is not particularly limited, and the shape of the concave portion that opens upward in which bath water accumulates is not particularly limited, such as a substantially elliptical shape or a substantially rectangular shape.

  And in the inner surface (inner surface) of the bathtub 1, a part is dented and the recessed part 2 as a handrail is formed. In the present embodiment, the recessed portion 2 having a substantially constant vertical width is formed horizontally over the entire circumference of the inner surface of the bathtub 1, but may be a part of the entire circumference of the inner surface of the bathtub 1.

  In this embodiment, the cross-sectional shape of the dent part 2 is a substantially rectangular shape with Rs formed at the corners, and the surface of the lower end part of the dent part 2 is a handle surface 3 made of a flat surface facing upward. .

  The vertical width of the recessed portion 2 is a width that allows an average human hand to be easily inserted, and is, for example, about 5 cm to 20 cm, preferably about 10 cm to 15 cm.

  Moreover, the depth width of the recessed part 2 shall be 5 cm-20 cm, for example, Preferably it is about 10 cm-15 cm.

  The upper and lower positions forming the dent portion 2 may be any position between the upper end portion and the lower end portion of the inner surface of the bathtub 1. When the weight is placed and the weight is put on, the arm can stand up by sticking to the handle surface 3, and it becomes easy to stand up.

  As described above, a part of the inner surface of the bathtub 1 is recessed to form the recessed portion 2, and the hand as the handle surface 3 on which the human hand can be placed with the lower end portion of the recessed portion 2 facing substantially upward. By configuring the sliding, even when the bather is weak in gripping force, when standing up in the bathtub 1, it is not necessary to hold the grip part or grip bar firmly to put on the weight and place the hand on the handle surface 3. The weight can be applied, it is possible to stand up easily, and the function as a handrail is sufficiently fulfilled.

  Moreover, since the recessed part 2 was provided in the inner surface of the bathtub 1, the back bottom face 21 of the recessed part 2 becomes a slip prevention of a hand, and a hand is just like what hands a hand on the upper end surface of the bathtub 1. The upper end surface of the bathtub 1 is not slid sideways.

  In addition, like a grip bar, there is of course no part of the body such as limbs, towels, bathing tools, or the like that get caught or caught in the gap between the bathtub 1 and the grip bar.

  Moreover, by forming the dent part 2 over the entire circumference on the inner surface of the bathtub 1, it is possible to place the hand on the handle surface 3 of the dent part 2 at any position on the entire circumference, and the usability is improved. is there.

  Further, as shown in FIG. 3, the recessed portion 2 having the handle surface 3 is used as an upper recessed portion 2a, and another lower recessed portion 2b is formed below the upper recessed portion 2a. Also good. The lower recess 2b is not particularly required to form the handle surface 3 at the lower end.

  In this way, the lower dent 2b is formed below the upper dent 2a, and the convex portion between the upper dent 2a and the lower dent 2b is defined as the grip 4. Thus, it is possible to hold the grip portion 4 by putting the hand on the handle surface 3 of the upper recess portion 2a and inserting the fingertip into the lower recess portion 2b.

It is a sectional side view of the principal part of one Embodiment of this invention. An embodiment same as the above is shown, (a) is a plan view, and (b) is a side view. It is a sectional side view of the principal part of other embodiment.
