Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic washbasin for a bathroom which can be used as a welfare tool for pumping hot water.

[0002]

2. Description of the Related Art At present, the aging of the population is accelerating the aging of the population, and the need for self-help tools (meaning tools devised and devised to make the activities around us independent) is increasing. ing.

[0003] For example, elderly people who have crippled fingers or hands,
In other words, there is a demand for the emergence of tools that are easy to use, even for elderly people who have weakened hands and fingers or whose fingers do not move well.

By the way, as shown in FIG. 6, a plastic one-pail (also referred to as a pail, for example, see Japanese Patent Laid-Open No. 9-37984) 20 as a bathroom appliance has a handle 21.
Has a maximum diameter of 7.5 cm, a minimum diameter of 2.5 cm, and an axial length of 7.5 cm, which are easy to grasp, and
Even if the strength of the fingers is weakened, the handle 21 extends the upper limbs to allow the wrist to move freely, and also makes it easy to fit the hand firmly, and as a result, it is difficult to slip and the ability of the hand can be fully exerted. , It has become an easy-to-use tool for pumping and pouring water for the elderly.

However, a general plastic one-cage 20
Because of its large depth and small opening area, it is difficult to use for other purposes such as washing, hand washing or towel washing like a washbasin with a morning glory opening.

Therefore, both the plastic one-basket 20 and the plastic washbasin may be provided in the bathroom, but it is common because the space of the bathroom and the use of the one-basket and the washbasin are troublesome. The bathroom wash basin, which is slightly shallower than the wash basin and has a small opening area, is generally used.

On the other hand, in a general wash basin, particularly in a bathroom plastic wash basin, for example, as pointed out in Japanese Utility Model Laid-Open No. 19384/1990, the flange of the wash basin is slightly folded back and has a fingertip. There was a problem that even if an adult does not enter deeply and fills the basin with hot water, even one adult is heavy with one hand and difficult to hold.

[0008]

Therefore, the conventional general plastic basin cannot be used as a self-help tool for the elderly at all. By the way, grip strength is 2
The maximum is 0 to 40 years old, and 10% reduction at 60 years old,
Since females are about two-thirds of males, ordinary washbasins, which are difficult for adult males to draw hot water and pour water, do not serve as self-help tools for the elderly.

[0009] Therefore, the present inventors ergonomically analyze the handling of the washbasin in order to make the plastic washbasin for bathrooms as easy to use as a plastic one-handed pail.
By investigating the actual condition of handling patterns,
The aim was to provide a plastic washbasin for bathrooms that can be easily used by care recipients and women and women, and tried hard development efforts.

That is, in terms of ergonomics, generally, the easiness of the "grasping" or "grasping" operation (grasping operation) is mainly due to the shape, size and weight of the article to be grasped. It is said that the ease of movement and the amount of force that can be exerted are determined by the balance with the ability of the hand.

In other words, it is said that the output of the hand increases as the easiness of movement such as grasping increases.

On the other hand, when the basin was held and the operation of pumping out hot water and pouring water was investigated, it was found that it was roughly divided into the following three patterns.

That is, a person who holds only the flange portion of the washbasin to pump out hot water, a person who holds his / her finger on the flange portion and the bottom ring to hold hot water, and drains hot water, and the like. It turned out that it was roughly divided into the patterns of people who hung their fingers on the side and grabbed them to draw hot water.

Therefore, the present inventors have made an earnest effort to develop a plastic wash basin that is easy to handle, from the viewpoints of the above ergonomics and the pattern of the actual handling survey.

[0015]

In order to achieve the above object, the present invention has the following features: 1) A hot water having a flange portion in which a curved portion and a folded portion are smoothly connected and a downward facing finger recess is formed on the back surface thereof. In a pumpable plastic washbasin, at a pair of facing portions of the flange portion,
By expanding the flange width to form a one-handed gripping portion, the flange portion is formed into an elliptical shape in plan view, and a large diameter is formed at a pair of facing portions of the flange portion on the short diameter side of the elliptical shape. A plastic washbasin for a bathroom, characterized in that by forming an arcuate notch, it is possible to easily grip the flange and the bottom ring by putting a finger on the flange, and 2) a curved portion and a folded portion. In a plastic washbasin that is smoothly connected and has a flange portion on the back surface of which a downward facing finger recess is formed, the width of the flange can be expanded at a pair of facing portions of the flange portion. By forming the one-handed holding portion, the flange portion is formed into an elliptical shape in a plan view, and the flange portion on the minor diameter side of the elliptical shape is opposed to one another.
By forming a large-diameter arc-shaped cutout portion at the paired portion, it becomes difficult to hold only the flange portion by the cutout portion, and as the gripping is facilitated by hanging the finger on the flange portion and the bottom ring, A plastic basin for a bathroom, characterized in that it is guided to grip the one-handed gripping part, and 3) A plastic for a bathroom in which the one-handed gripping part according to claim 2 is formed with a non-slip welfare tool It is in a wash basin, and 4) is a plastic wash basin for a bathroom in which the slanted outer surface of the wash basin according to claim 2 or 3 has a satin finish to prevent the fingertips from slipping.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 is a schematic perspective view of an embodiment of the present invention, FIG. 2 is a partial sectional side view (left side sectional view, right side side view) of FIG. 1, and FIG. 3 is a plan view (lower figure) and bottom view of FIG. (Upper diagram), FIG. 4 is an enlarged cross-sectional view of the main part of FIG.
5A is a cross section of the grip portion, FIG. 5B is a cross section of the arcuate cutout portion, and FIG.
Is an explanatory diagram.

The plastic washbasin according to the embodiment of the present invention, more specifically, the plastic washbasin for bathroom is suitable as a welfare tool for facilitating the operation of pumping hot water and pouring water and washing the washbasin, hand wash and towel etc. Is as usual.

The plastic wash basin of this specification (refer to the synthetic resin processed product wash basin in the appendix of the Ordinance for Enforcement of the Household Goods Quality Control Act) includes general wash basins, but particularly plastic wash basins for bathrooms ( (Also called a bathtub).

This plastic basin for bathroom (hereinafter referred to simply as "basin") 1 will be outlined in accordance with the pattern of the actual handling survey.

In FIG. 5, (A) shows only the flange portion (generally, the protrusion portion extending over the entire circumference) of the washbasin 1, the thumb (first finger) and the other second to second portions. 5 shows the case of a person performing an operation of pumping out or pouring hot water in a bathtub by grasping it with five fingers. In this case, in order to make it easy to grasp, the protrusion length of the flange portion 2 (also called the flange width) ) Is increased so that the fingertips of the second to fifth fingers other than the thumb, particularly the fingertips of the second and third fingers, can be deeply inserted into the downward finger-holding concave portion 3 formed on the back surface of the flange portion 2,
It becomes easy to grip, and as a result, the gripping force of the hand is exhibited well.

In particular, the flange portion 2 having a large flange width
Since only one of the plastic tubs 20 is gripped by the user, the user can easily grasp the grip, smooth the rotation of the wrist, and more effectively output the hand.

In this case, even for an elderly person whose fingertips do not move properly, if four fingers are aligned and bent, one of the fingers easily catches on the finger-holding concave portion 3 and is easily grasped.

Therefore, in this washbasin 1, the flange portion 2
One pair of facing portions having a large flange width are provided to face each other to form a one-handed gripping portion 12 for the washbasin 1 (see FIG. 1), and when smoothly connected to the conventional flange width portion, a plan view is obtained. Thus, only the flange portion 2 is formed into an elliptical shape, which is a preferable design and prevents the flange portion 2 from cracking. For example, the major axis has an elliptical shape with an increase of about 5 percent with respect to the minor axis.

Therefore, the basin 1 becomes slender as a whole and becomes a tool extended from the upper limb like the plastic one-cage 20 as described above, which is easy to use.

Of course, the body 4 of the washbasin 1 (see FIG. 1) is
Since it is circular in plan view as before, it can be used without any problems when it is used for washrooms, etc., and there is no problem with stacking at the time of factory / warehouse shipment.

If the main body 4 of the washbasin 1 has an elliptical shape having a major axis in the direction of the major axis of the flange 2 in plan view, even if the work such as washing is slightly sacrificed The same operation becomes easier.

Next, the same (B) shows the flange portion 2 of the washbasin 1.
The bottom ring 5 (see FIG. 2) and the bottom ring 5 (see FIG. 2) are hung on the flange portion 2 side, and the third to fourth fingers are hung on the bottom ring 5, respectively. In this case, the distance between the top of the flange portion 2 and the tip of the bottom ring 5 is shortened to facilitate gripping.

Therefore, if the washbasin 1 is made shallow, the bottom of the washbasin 1 is widened to increase the diameter of the bottom ring 5, or the bottom ring 5 is formed with a toku-bale-shaped convex portion, it is easy to grasp. As a result, the gripping force can be satisfactorily exhibited.

In this case, the distance that the third to fourth fingers reach the first finger (105 mm or less in the case of a woman) is shortened even in a person with a small hand (for example, a woman or a woman) or an elderly person whose fingers are bent. It will be easier to grasp.

Therefore, in the washbasin 1, the bottom portion 15 (see FIG.
(See) is formed in the shallow bottom. In particular, if the third finger, which exerts the most force of the finger, is sufficiently caught by the bottom ring 5, it does not have to be so shallow.

As in the case of (A) above, in the washbasin 1 in which the flange portion 2 has an elliptical shape, this (B)
In the case of applying the shortening of the reach of the finger as in the case of, the pair of large diameters are opposed to the portion of the folded portion 11 (see FIG. 4) of the flange 2 on the short diameter side of the ellipse. If the arcuate notch 6 is formed, the flange width of the flange portion 2 at this portion is originally small, and since it is notched by the arcuate notch 6, the reach of the finger is further shortened, and conversely. The position of the one-handed gripping portion 12 having a large flange width is also specified, and the use of the one-handed gripping portion 12 is guided or guided.

Of course, the arcuate notch 6 is formed by the folded-back portion 1.
It may be formed over 1 and the curved portion 10.

Next, in the same (C), the flange portion 2 of the washbasin 1 and the inclined outer side surface 7 (see FIG. 1) having a bulge outward are hooked on the flange portion 2 side with the first finger, and the The case of a person performing an operation of drawing hot water by bringing the second to fifth fingers into close contact with the inclined outer side surface 7 is shown. In this case, in order to make it easy to grasp, the inclined outer side surface 7 is textured (also called satin finish). , By providing a fine uneven pattern on the surface, for example, to prevent the fingertips from slipping) 8 (see FIG. 3), the fingertips of the second to fifth fingers are brought into close contact with each other to fit the hand well, It reduces grip strength and makes it easier to grab. As a result, the gripping force can be satisfactorily exerted and the washbasin 1 can be easily used.

In this case, even a person with a small hand can easily grasp it, which is convenient for an elderly person who has difficulty applying force to his fingertips.

As in the case of (B) above, in the washbasin 1 in which the pair of arcuate notches 6 are formed, the second to fifth parts are provided.
The fingers can be naturally aligned and fitted to the inclined outer side surface 7 to be in close contact.

Therefore, if the washbasin 1 as a welfare tool is to be constructed, various self-help tools can be provided by appropriately combining the patterns.

Next, the washbasin 1 will be described in detail. 1 to 4, the washbasin 1 is a PP resin (also referred to as synthetic resin or thermoplastic resin) injection-molded product, and the weight of the washbasin alone is 230 g (about 10% reduction compared to the conventional washbasin),
The maximum hot water capacity is 3.1 liters, and the total height is about 90 m.
m, the height of the main body 4 is 76 mm, the opening diameter of the main body 4 is about 230 m
mφ, the diameter of the bottom portion 15 of the body 4 is about 160 mmφ, and the thickness of the body 4 is about 2.2 mm. Of course, this number is preferred, but the invention is not so limited.

The flange portion 2 is smoothly connected in a folded shape from the trumpet-shaped inclined portion 9 and at least the curved portion 10 and the folded portion 11 in its cross section, and has a finger-holding concave portion 3 facing downward on the back surface thereof. .

The wall thickness of the folded-back portion 11 is set to 4 mm to increase the volume so as not to cause an undercut at the time of injection molding, to prevent deformation of the opening of the washbasin 1 and, in the case of the pattern (A), Good hooking of the second to fifth fingers in gripping.

Further, in the case of gripping the pattern of (A), the flange width a of the flange portion 2 for gripping, that is, the one-hand gripping portion 12 is about 20 mm at maximum,
In the portion of the flange portion 2 that is not gripped, that is, in the arcuate notch portion 6, the flange width b is about 14 mm at maximum.

Therefore, in order to prevent the selection of the one-handed gripping portion 12 to be gripped from being confused, one or both top faces are provided with two rows of a large number of independent potches 14, 14 (slip prevention).
Is integrally projected to clearly indicate the gripping position and prevents the first finger from slipping.

The arcuate notch 6 used for gripping the pattern of (B) is formed by an arc having a circle radius R = 500 mm, which does not impair aesthetics and naturally causes the second to fifth fingers. Are arranged.

The embossing 8 used for gripping the pattern (C) is performed from the trumpet-shaped inclined portion 9 of the flange portion 2 through the inclined outer side surface 7 to the outer diameter base side of the bottom wheel 5. To prevent slipping on your fingertips. Of course, texture processing 8
In some cases, the processing cost can be reduced.

Further, the embossing 8 is performed by the bottom portion 15 of the washbasin 1.
It is also installed on the outer surface of the inner ring of the bottom ring 5 to prevent the third finger from slipping in the pattern (B).

[0045]

According to the present invention, a pair of hand-holding portions for a washbasin is provided at a pair of opposing portions of a flange portion to widen the flange width and hold only the flange portion to perform hot water pumping operation. Therefore, there is no hindrance to the work such as washing, and the third to
Not only the catching of the fourth finger becomes good, but the operation is smooth and the output of the hand can be exerted by handling one hand tub. As a result, it is possible to provide a welfare tool that is preferable as a self-help tool for the elderly and the like.

In addition, an arcuate notch is provided on the minor diameter side of the elliptical flange to make it difficult to grip only the flange, and to guide the grip to the one-hand grip to prevent mishandling.

Particularly, since the pair of one-handed gripping portions is formed,
The handle is easier to handle than a single-handed tub, and since the operation can be performed by placing a finger on the arcuate notch and the bottom ring, the basin can be handled in various ways.
