Description

  The present invention relates to a toilet seat cushion (also referred to as a “toilet seat cover”) that covers an upper part of a toilet seat of a Western-style toilet.

Conventionally, in order to avoid a cold feeling or a hard feeling when sitting directly on a synthetic resin toilet seat, a cover that covers the toilet seat has been used. In particular, due to the recent increase in power saving awareness, an increasing number of people wear toilet seat covers instead of warming the toilet seat or lowering the set temperature, so the demand for toilet seat covers is great.

As such a cover, a knitted bag-like one or a single knitted piece with a fastener was initially used. This is also called “first generation” and is generally called “toilet seat cover”. When this toilet seat cover is used for a U-type toilet seat, there is no problem, but in the case of an O-type toilet seat and a toilet seat with a washing and heating device, there is a drawback that the installation is very troublesome.

Recently, a pair of crescent-shaped base fabric type covers that are attached to the toilet seat surface are increasing. This is also called "second generation" and is often called "toilet seat". As a method of attaching the toilet seat sheet to the toilet seat surface, a method of laminating a self-adhesive resin on a base fabric (for example, JP-A-2002-233476) is common. The toilet seat has the advantage that it is easy to wash and install, but because it is flat, it is inevitable that the human body and the toilet seat may be in direct contact with each other at the edge of the seat. It was not a thing. There was also a problem of turning up at the tip during use.

Furthermore, there were few toilet seat covers and toilet seat sheets that could be used for all three types of toilet seats, including the O-type, U-type, and others with washing and heating devices.

JP 2002-233476 A

  The present invention provides a so-called third generation cover (herein referred to as a “toilet seat cushion” for the sake of convenience in order to distinguish it from the former two), which overcomes the above-described problems of the toilet seat cover and toilet seat. Objective. In particular, the main object of the toilet seat is to eliminate the greatest problem in the toilet seat, that is, the discomfort given to the user by direct contact between the human body and the toilet seat at the edge of the planar seat.

  The present inventor considered that the investigation from the human body side and the investigation from the toilet seat side are indispensable for removing this discomfort.

The basic standard human body dimensions required for investigation from the human body side are as follows ("Human Data for Design", edited by Biotechnology Research Institute, published by Human Life Engineering Research Center).

As data necessary for the investigation from the toilet seat side, the following maximum value and minimum value were obtained by measuring the dimensions of 11 types of toilet seats currently sold in Japan at the following three locations a, b, and c. The rear side where the toilet seat center line and the toilet seat opening intersect is defined as “0 point”.

<Significance of 0 points>
From experience, a horizontal line passing through the zero point of the toilet seat may be regarded as a buttock trailing edge.
<Significance of point a>
Since the average distance between the sitting position and the trochanter is 104.6 mm, it can be regarded as a distance from almost 0 point to point a (from 0 point to 100 mm forward).
The seating surface width is in the direction perpendicular to the distance between the sitting position and the trochanter point.
In the measurement results of various toilet seats, the maximum toilet seat width is about 370 mm, and substantially coincides with the lateral width at the position of point a (see the illustration in Table 2). The above-mentioned human body seating surface width (average 348.1 mm) is also the maximum at point a, but the maximum toilet seat width of about 370 mm is considered to be a distance that a person can naturally sit with a sufficient margin.
<Significance of point b>
It is a substantially intermediate position between points a and c. It was provided to increase the measuring position.
<Significance of point c>
At the time of urination / excretion, the kneecap cannot be brought into close contact with the seated state as shown in the figure showing the seating surface width. As the posture of opening the knee, the c-point (position shifted by 40 mm parallel to the center line) was determined with reference to the tip crack size (65 mm to 75 mm) of the U-shaped toilet seat.
<Thigh diameter>
Assuming that the thigh is cylindrical, the thigh diameter D is 528.4 mm / π = 168 mm. Actually, the thigh is not a cylinder, and when you sit down, it is close to an ellipse whose shape has collapsed.

Based on these data, it was considered necessary to improve the area where the thighs and toilet seat contacted (“cold sensing range”).

  It can be seen that the thighs (average diameter 168 mm) are within the plane range (T). Even if the user sits down and fully opens the kneecap or opens to the point c, it is still within the plane range (T). In addition, regarding the three-dimensional range (S), the thigh diameter of 168mm is larger than the maximum measured value of 115mm at point a, but experience shows that the thigh protrudes into the air above the toilet seat, so it does not contact the toilet seat. It is enough.

It has been found that the object of the present invention can be achieved if it can cover at least the cold sensing range and does not hinder the operation of the washing nozzle. Note that this cold sensing range needs to be covered at least, and does not exclude the range exceeding this cold sensing range. For example, as illustrated in the following embodiments, the toilet seat cushion may extend backward beyond the plane range (T), and it is preferable.

The toilet seat cushion of the present invention is a toilet seat cushion having a pair of symmetrical left and right main bodies, and each cover covers at least a range (T and S) where the thigh and the toilet seat come into contact with each other and hinders the operation of the washing nozzle. It has a size and shape sufficient to prevent it. That is, it has a size and shape that has the width of the maximum value at the points a to c and can cover the minimum value.

Specific dimensions of the toilet seat are as follows: in FIG. 6 attached, H is 380 mm to 450 mm, W is 170 mm to 210 mm, W1 is 100 to 140 mm, W2 is 110 to 140 mm, W3 is 100 to 130 mm, preferably H Is 390 mm to 420 mm, W is 180 mm to 200 mm, W1 is 110 to 130 mm, W2 is 120 to 140 mm, W3 is 110 to 130 mm, and most preferably H ≒ 405mm, W ≒ 185mm, W1 ≒ 120mm, W2 ≒ 130mm, W3 ≒ 115mm. Where H is the length in the vertical direction, W is the length in the horizontal direction, W1 is the toilet seat width at the point of 100mm forward from 0 point, W2 is the width of the toilet seat at the point of 200mm forward from point 0, W3 is from the center line It is the toilet seat width at a point shifted by 40 mm in parallel (Claim 1).

Preferably, an anti-slip process is applied to the back side of the main body (Claim 2).

  Preferably, at least two attachment strings are attached to the main body, one of which is near the point c (Claim 3).

Preferably, the attachment string is a combination of a rubber belt and a hook-and-loop fastener.

  Preferably, the surface fastener is a combination of male and female surface fasteners, and the female side is preferably wider than the male side (Claim 5), but may have the same width.

The toilet seat cushion of each claim of the present invention covers the toilet seat plane and the side that the user's buttocks and thighs may touch in various toilet seats sold by the toilet seat manufacturer in the past or currently sold, Does not interfere with the operation of the cleaning nozzle. Therefore, since the user's buttocks and thighs do not touch the toilet seat directly, a cold touch or a hard touch can be avoided. Moreover, the toilet seat cushion of each claim of the present invention can be applied to all three types of toilet seats of the O type, the U type, and those equipped with a washing and heating device.

According to the toilet seat cushion of claims 2 to 5, the ease of attachment to the toilet seat and the stability after the attachment are improved.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view of a state in which a toilet seat cushion according to one embodiment of the present invention is mounted on a toilet seat. It is a top view of the toilet seat cushion. It is a side view of the toilet seat cushion. It is a rear view of the toilet seat cushion. FIG. 5 is a VV cross-sectional view of FIG. 2. It is a toilet seat cushion top view which shows the dimension measurement reference | standard of the same toilet seat cushion.

  As shown in FIG. 1, the toilet seat cushion 1 is a pair of left and right symmetry and is used by being attached on the toilet seat 5 at the upper end of the toilet 4. An exposed portion 6 is provided so as not to hinder the operation of a cleaning nozzle (not shown) that appears and disappears from around the zero point.

  2-5, the toilet seat cushion 1 consists of the deformation | transformation ellipse-shaped main body 2 and the attachment string 3 for mounting | wearing with a toilet seat.

Since the surface 21 of the main body 2 is a portion that is in direct contact with the human body, it is preferable that the surface 21 is piled or shirred so as not to cause discomfort. The main body edge 23 is edged.

The back surface 22 of the main body 2 is preferably subjected to anti-slip processing. Examples of the anti-slip process include a method in which a large number of small protrusions 14 are provided on a front surface polyurethane resin sheet, a method in which silicone particles are sprayed and heated, a method in which silicone particles and polyurethane particles are kneaded and heat-molded.

The attachment cord 3 needs to be provided at two or more places. In the illustrated embodiment, it is provided at two locations. The attachment cord 3 includes an elastic rubber belt 31 on the side close to the main body and a surface fastener 32 on the far side. The thickness of the attachment cord 3 depends on the length of a leg (not shown) on the back of the toilet seat, but is preferably 5 mm or less in order to support all models.

As for the setting position of the attachment string 3, when there are two attachment strings, one is preferably between a and b, and the other is near c. The reason why it is arranged in the vicinity of c is to prevent the tip of the toilet seat cushion from turning up.

As shown in Table 2, the length of the attachment string 3 is determined in consideration of the dimensional difference of 25 mm at the maximum through the ac seat width of each manufacturer.

The male and female surface fasteners of the attachment cord 3 are preferably set so that the female side 33 is wider than the male side 34. If the male and female fasteners are attached to each other at the time of washing, the male hook will not be caught on other laundry, but if the male hook is partially exposed, there is a risk . Therefore, it is preferable to make the male hook small to eliminate the exposed portion, and even if doing so, the adhesive force is not greatly affected. However, it is also possible to use male and female face fasteners of the same width when no such consideration is required.

Further, the toilet seat cushion has a mark (not shown) because it is difficult to understand the rear end. The mark is a display such as “front” or “front”, and is printed on the back side or sewed with a label.

When this toilet seat cushion 1 is attached to the toilet seat 5, as shown in FIG. 6, it is used in various toilet seats sold by the toilet seat manufacturer in the past and currently sold (the outline is expressed by thin lines in FIG. 6). It is possible to completely cover the toilet seat plane and side surface (cold sensing range) that can be touched by a person's buttocks and thighs, and does not hinder the operation of the washing nozzle.
