Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a handrail for a bathtub, and more particularly, to a handrail that is detachably attached to an upper end portion of a thick side wall plate (also referred to as an apron) of the bathtub.
[0002]
[Prior art]
A variety of welfare tools are now on the market, as the “Welfare Tool Law” was enacted in 1993.
[0003]
Handrails for bathrooms are also widely used as easy and convenient welfare tools, and are useful for bathing people with physical disabilities, the elderly and children of lower grades (hereinafter referred to as bathers).
[0004]
Of these handrails for bathrooms, when the handrails are fixed directly to the bathroom wall, especially when an amateur fixes them to an existing wall, some wall materials may not have sufficient fixing force, so an unexpected peeling accident May occur.
[0005]
Therefore, handrails for bathtubs that are easy to check the strength (according to the JIS standard bath apron surface deformation test) and can be easily installed even by an amateur have come to be widely used.
[0006]
Various proposals have been made regarding handrails for bathtubs. For example, Japanese Utility Model Publication No. 3-39482, Japanese Utility Model Publication No. 3-60590, Japanese Utility Model Publication No. 4-4630, Japanese Utility Model Publication No. 4-43189, Japanese Utility Model Publication No. 4-4889, Japanese Utility Model Application Publication No. 4-54290, Japanese Various proposals have been made by Kaihei 6-48490, JP-A-11-47016, and the like.
[0007]
The present applicant has also proposed the handrail for bathtubs shown in FIG.
[0008]
This will be described. This bathtub handrail 100 includes a downward U-shaped extending member 2 and a pressing plate 5 with a handle 104 in the bathtub for fixing the extending member 2 to the apron 3 (see FIG. 2) of the bathtub. The gripping member and a downward U-shaped vertical gripping portion (also referred to as a grip) 6 for a bather standing outside the bathtub of the straddling member 2, etc., and the pressing plate 5 is a stainless steel plate. The elastic protective plate 7 is attached to one surface thereof, and one end of a screw rod 108 is connected to the central portion of the other surface via a pin coupling mechanism.
[0009]
The screw rod 108 is screwed to a nut loosely fitted to one foot plate 2a of the straddling member 2.
[0010]
The handle 104 is fitted on the other end side of the screw rod 108 via the nut.
[0011]
In addition, the handle 104 is formed with a cavity portion in which the other end side of the screw rod 108 can be screwed back and forth in the axial direction.
[0012]
Therefore, if the handle 104 is rotated, the nut rotates integrally. Therefore, even if the other end of the screw rod 108 is screwed back and forth in the cavity, and the handle 104 is rotated, the handle is not moved in the bathtub. The position is not changed.
[0013]
Therefore, the handrail 100 for a bathtub is convenient for a bather or the like that can be comfortably provided with some support when the bather enters and leaves the bathtub, and the position of the handle 104 in the bathtub does not change. Therefore, it does not get in the way, and it has a feature that the bath lid can be formed with the handrail 100 attached.
[0014]
By the way, not only the handrail 100 for bathtubs but also most handrails for bathtubs are composed of a single grip 6 parallel or orthogonal to the apron 3 of the bathtub in plan view. Conceivable.
[0015]
That is, a person who takes a bath by gripping the handrail 100 for the bathtub enters the bathtub while moving the hips horizontally, turns 90 degrees around the hips, or just enters the apron 3 Even more, when entering the bathtub with both hands (see Japanese Utility Model Publication No. 4-4630), enter the bathtub in the way you want, but in either case, hold the grip with both hands and enter the bathtub. In order to do so, there is a problem that this grip is enlarged, and as a result, an excessive moment acts on the handrail attachment portion (pressing plate 5), which may lead to an unexpected situation.
[0016]
On the other hand, two grips, so-called twin-grip type handrails, are disclosed in the utility model registration No. 2547487, JP-A-1-320306, JP-A-8-140880, and the above-mentioned facts proposed by the applicant. As already known in Japanese Laid-Open Patent Publication No. 4-4889, in such a handgrip of a twin grip type, for example, two downward U-shaped grips are substantially orthogonal or C-shaped in plan view on the apron of the bathtub. If you try to take a bath using both of these grips one at a time and using both hands almost simultaneously, the gripping position will not be parallel to your shoulders and your body will be extremely unnatural. As a result, there was a problem that it was difficult to use. Therefore, there was no idea of using both hands in the conventional twin-grip handrail.
[0017]
[Problems to be solved by the invention]
Therefore, the present invention is mainly intended to solve the above problems, and if necessary, a caregiver can grip one grip and a bather can grasp the other grip to facilitate care. .
[0018]
[Means for Solving the Problems]
In order to achieve such an object, the present invention comprises: 1) a bather's grip provided lower in the vicinity of the upper part of the apron of the bathtub; The two grips having substantially the same shape in outline view are erected substantially parallel to the inner and outer surfaces of the apron, so that the gripping positions of the grips with both hands of the bather are parallel to both shoulders. The bathing handrail is characterized in that the body of the bather is leaned forward to make it easy to raise its feet, and 2) used in a manner straddling the apron of the bathtub In the bathtub handrail comprising a downward U-shaped sheet metal straddling member and a bather grip erected on the straddling member, the grip is provided lower in the vicinity of the upper part of the apron of the bathtub. In the shape of a letter or a semicircle In addition, the two grips, which are configured by a vertical gripping body and are substantially the same in external view, are erected substantially parallel to the inner and outer surfaces of the apron so that the bather can grip with both hands. The gist is a handrail for bathtubs according to claim 1 or 2 in which one of the two grips is fixed up and down freely.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
The invention will be described in more detail by means of an embodiment shown in the accompanying drawings.
FIG. 1 is a schematic perspective view of a first embodiment of the present invention, FIG. 2 is a schematic perspective view of a second embodiment of the present invention, FIG. 3 is a detailed partially cutaway side view of FIG. 1, and FIG. FIG. 5 is a plan view of FIG. 3, and the description of the same or common parts as in FIG. 6 is simplified or omitted.
[0020]
Both the handrails 1 and 1A for the bathtubs of the first and second embodiments of the present invention employ a screw-type pressing plate tightening mechanism, that is, a gripping member, and the tightening stroke is the thickness of the apron 3. On the other hand, the adjustment range is large from the minimum value to approximately twice the value or to the value of 1/3 times the minimum value, such as a range that can be adjusted from 45 mm to 80 mm or a range that can be adjusted from 80 mm to 115 mm. It can be expanded to a wide width, and it is generalized to cope with the diversification of the thickness of the apron 3.
[0021]
In addition, the screw retraction stroke range of the screw rod 8 is restricted to be reduced so that the screwing operation is facilitated, and as a result, the tightening force can be made uniform.
[0022]
The feature of the handrail 1 for a bathtub according to the first embodiment of the present invention is, as shown in FIG. 1, in particular, a so-called twin grip type, and these twin first and second (both main and auxiliary) are configured. The grips 6 and 6a are erected on the straddling member 2 made of a metal such as a downward U-shaped stainless steel.
[0023]
This straddling member 2 is provided with a pressing plate 5 with a handle provided inside the bathtub so as to be detachably fixed to the apron 3 of the bathtub, that is, a screw type pressing plate tightening mechanism is provided. Yes.
[0024]
Here, the first and second grips 6 and 6a having a downward U-shape (including a substantially semicircular shape) have substantially the same shape, in particular, the same height in external view, and moreover than the conventional example described above. The bather, such as an elderly person, holds both the first and second grips 6 and 6a with one hand in each hand, with the height being lowered to about half or less, and in parallel with the upper part of the apron 3 near the inner and outer surfaces. At the same time, it is gripped to enter the bathtub. Of course, only one grip may be used.
[0025]
Therefore, it is not only convenient for bathers with weak grip and strength, but using both hands makes the body lean forward and naturally lowers its posture, which makes it easier to lift up the apron 3 Easy to get over safety.
[0026]
As a result, at the tightening point where the handrail 1 is attached to the apron 3, even if these grips (6, 6a) are used with both hands, the bather can be configured to be low by gripping the two grips. It is possible to suppress an excessive moment due to the arm strength, weight, etc., and thus to obtain the reliability of handrail attachment.
[0027]
In particular, if the 2nd grip 6a inside the bathtub is configured to be able to rise and fall, when entering the bathtub, this is raised and fixed, while lying and fixed horizontally during bathing, the body during bathing It can be held stably.
[0028]
Of course, the bath lid can be closed without a gap if it is laid down horizontally.
[0029]
If necessary, if the bather holds the second grip 6a of the two standing grips (6, 6a) and the caregiver (caregiver or adult) holds the first grip 6, slipping will occur. Easy care in the bathroom is safe, and when taking a bath in the bather's habit, when taking a bath by lifting the handrail 1 so that the caregiver does not come off by pressing the first grip 6 Various effects of twin grip type can be achieved.
[0030]

The grip handle 4 with the potch 10 is fitted on the nut.
[0032]
The nut with flange is rotatably supported by a foot plate 2a located in the bathtub of the straddling member 2. When the grip handle 4 is rotated forward and backward, the nut with flange rotates integrally with the screw rod. As a result, the pressing plate 5 is pressed against the inner surface of the apron 3 or released.
[0033]
The grip handle 4 is an injection molded product made of foamed PP (synthetic resin), and its shape is composed of a disc-shaped grip portion 9 and a small cylindrical base portion 9A. Two (plural) small hemispherical pots 10, 10,... Are integrally formed.
[0034]
The diameter of the disc-shaped gripping portion 9 is about 65 to 70 mmφ as a convenient dimension for an eagle gripping by an adult, the virtual outer diameter composed of these small hemispherical potches 10 is about 75 mmφ, and the thickness of the disc is about 30 mm is set so that even a user with a weak fingertip can conveniently grasp the eagle, and the pressing force required for the pressing plate 5 is generated. The length of the grip handle 4 in the horizontal direction, that is, the amount of protrusion at the bathtub is suppressed to about 50 mm so that it does not protrude so much.
[0035]
