2. Description of the Related Art With the aging of people's longevity, individual interest in health care is increasing. Particularly in recent years, self-health check for the purpose of early detection of diseases and health management during or after treatment of diseases has become an important theme. Urine is an important source of personal health information, and quantitative analysis of urinary sugar, urinary protein, urobilinogen, occult blood, and other urinary components enables pancreatic disorders such as diabetes, liver disorders, kidney disorders, and other functions. The disorder can be examined non-invasively. Therefore, various devices have been proposed that can support the individual's health check by sampling and analyzing urine using a toilet at home, workplace or the like.

In the prior art, it has been proposed to form a urine collecting portion on the bowl surface of the toilet bowl and collect the urine excreted on the bowl surface in the urine collecting portion for sampling (eg, Japanese Patent Laid-Open No. 59-217844). , JP 63-184057, JP 63-29096
No. 1 and JP-A-1-178866). The collected urine sample is analyzed by a liquid chromatographic method, a test strip method, or a polarographic method. This urine collection method using the bowl surface of the toilet bowl has the advantage that urine excreted in the toilet bowl can be easily collected, but it has the drawback that it requires a special toilet bowl with a urine collection portion formed on the bowl surface. .

JP-A-7-98660 and WO95
/ 18374 discloses a urine collecting device capable of sampling urine by utilizing a toilet equipped with an existing standard toilet bowl. In one embodiment, the urine collection device includes a frame mounted to the back of the toilet seat, and a swing arm carrying a urine collection container is swingably supported on the frame. Urine is collected by swinging the arm by the motor and moving the urine collection container in the toilet bowl space. After use, the urine collection container and the swing arm are stored under the toilet seat and washed by spraying washing water. This urine collecting device has an advantage that an existing conventional toilet bowl can be used as it is.

However, a drawback of this toilet seat mounted urine collection device is that the seat must be machined to a greater or lesser extent to mount the device on an existing toilet seat. That is, to attach the frame of the urine collection device to the existing toilet seat,
At least part of the existing leg of the toilet seat must be removed. Another difficulty is that there are restrictions on the type of toilet seat to which the urine collection device can be attached. That is, since the device frame is designed to be attached to the flat back surface of the toilet seat, it cannot be attached to a toilet seat of a type that does not have a flat back surface. In that case, it is necessary to replace the toilet seat, resulting in extra expense and trouble.

FIG. 24 of Japanese Unexamined Patent Publication No. 7-198660 discloses a rim-mounted urine collecting device adapted to be hooked on the rim of a toilet bowl. This urine collecting device is provided with a support member extending over the side portion of the rim, and a swing arm having a urine collecting container is swingably supported on the support member. The middle part of the support is curved along the inside of the rim and its front part is adapted to be supported on the toilet rim by a horizontal projection. A storage chamber is formed in the front part of the support, and the urine collection container is stored and washed when not in use. This rim-mounted urine collecting device has an advantage that it can be attached to a toilet bowl very easily regardless of the type and size of the toilet bowl or the toilet seat.

[0007]

However, in order to put this rim-mounted urine collecting device into practical use, some problems must be overcome. That is, since the toilet with this urine collecting device must be used for daily use with the urine collecting device still attached, it is desirable that the daily usability and appearance of the toilet are not impaired as much as possible.

However, since the swing arm of this urine collecting device is exposed from the intermediate portion of the support body and the rim is almost exposed, the swing arm, the support body and the rim are exposed to urine as daily use of the toilet. There is a risk of being contaminated by such things as. Particularly, when a standing man raises urine with the toilet seat flipped up, any one of the swing arm, the support, and the rim is easily polluted by the dropped urine drops. Since the rocking arm and the support have separate three-dimensional outer surfaces, and the two are close to each other, cleaning once takes a lot of time. Furthermore, the rim must be cleaned separately from the urine collector.

Further, when the urine collecting device is attached to a toilet bowl for a male standing urine and the toilet seat is flipped up, the exposed swing arm and the support are visible. As a result, the user feels a lot of discomfort and the usability of the toilet deteriorates.

Further, since the portion for hooking the support on the rim is small, and the support extends only over the quadrant of the rim from the side to the front of the rim, the urine collecting device is firmly fixed to the toilet bowl, It is difficult to stably position the toilet bowl at a proper position. As a result, the position of the urine collection device becomes unstable. If the trajectory of the movement of the urine collection container deviates from the central surface of the toilet bowl due to improper positioning, it is impossible to reliably collect urine. Further, since the intermediate curved portion of the support is elongated, the strength is insufficient.

Still another problem of this urine collecting device is that the user sitting on the toilet seat has a narrow gap between the existing toilet seat and the rim so that the toilet seat interferes with the rotation axis of the swing arm. It means that the rotating shaft of the swing arm may be damaged due to the weight of the.

Therefore, an object of the present invention is to provide a rim-mounted urine collecting device which is convenient for daily use of a toilet. Another object of the present invention is to provide a rim-mounted urine collecting device having a simple outer shape and easy to clean. Still another object of the present invention is to provide a rim-mounted urine collecting device in which the swing arm is less likely to get dirty.

Another object of the present invention is to provide a rim-mounted urine collecting device which has a simple appearance and which does not give a feeling of strangeness during normal use of the toilet. Another object of the present invention is to provide a rim-mounted urine collecting device that can be firmly fixed to a toilet bowl and has excellent strength. In another aspect, an object of the present invention is to provide a mounting method capable of easily mounting a rim-mounted urine collecting device to an existing toilet bowl.

[0014]

According to the present invention, there is provided a support which can be attached to a rim of a toilet bowl, and a swinging shaft which extends in the transverse direction of the toilet bowl and is horizontally pivoted about a horizontal rotation axis which is spaced upward from the upper surface of the rim side portion. A swinging arm supported by the support as much as possible, a urine collecting container carried on a free end of the swinging arm, a resting position close to the inside of the front part of the toilet rim, and a urine collecting located in the toilet bowl space. A rim-attached urine collecting device for collecting urine excreted in a toilet bowl for urine analysis, comprising: a driving unit that swings the swinging arm to move the urine collecting container to and from a position. In the above, the support is formed so as to be curved along the contour of the substantially first half of the rim of the toilet bowl in plan view and to cover the substantially first half of the rim, and the support is placed on the upper surface of the substantially first half of the toilet rim. Characterized by attaching a urine collection device to the rim It is intended to.

Since the support has such a shape, the urine collecting device can be stably and easily attached to the toilet rim. This support covers the front half of the rim and the swing arm, so that the rim and swing arm are not contaminated by men's urine. Only the upper surface of the support is soiled with urine, which can be formed on one continuous surface,
It can be easily cleaned even if it becomes dirty. Further, since the swing arm is hidden by the support, the appearance of the toilet when the toilet seat is flipped up is improved, and the discomfort can be reduced.

In a preferred embodiment, at least a portion of the support has a grooved cross section that spans the top of the rim of the toilet bowl. With such a sectional shape, the attachment to the rim becomes more stable.

Preferably, the support is removably locked to the rim of the toilet by locking means which engages the inner shoulder of the rim, the locking means being removably connected to the rear of the support. The urine collecting device is firmly fixed to the toilet simply by placing the support on the rim and connecting the locking means to the rear part of the support.

The support is preferably substantially hidden by the toilet seat in plan view. With this shape, the toilet seat looks good when the toilet seat is brought to the use position,
There is no obstacle when sitting on the toilet seat and using the toilet.

In a preferred embodiment, the top wall of the support has a lateral region for supporting the front legs of the toilet seat. When the toilet seat is folded down into the use position, these lateral areas are sandwiched between the front legs of the toilet seat and the upper surface of the rim, so that the toilet seat is lifted by the thickness of the lateral area. This increases the gap between the toilet seat and the upper surface of the rim, thus preventing the toilet seat from interfering with the swing arm. Also, the support is securely fixed to the toilet bowl according to the weight of the user. Preferably, these lateral areas have a predetermined front-rear extent and are adapted to fit toilet seats with different leg mounting positions.

The present invention also provides a method for height-adjustably mounting this rim-mounted urine collecting device to an existing toilet bowl. The above-mentioned features and effects of the present invention, as well as other features and advantages, will be made clear by the description of the following embodiments.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, FIG. 1 shows a urine collecting device 10 of the present invention attached to an existing toilet bowl of a toilet. Toilet is a conventional toilet bowl of any type 1
2, the toilet flushing water is supplied from the cistern 14, for example. In the illustrated embodiment, the toilet is equipped with a housing 16 containing a conventional bidet device (not shown), and the toilet seat 18 and toilet lid 20 are pivotally supported on the bidet device housing 16 in a known manner. There is. However, the bidet device can be omitted, in which case the toilet seat and toilet lid can be attached to the toilet bowl in a known manner by a pair of toilet seat stanchions. Toilet seat 18 is of any type conventional and comprises, for example, four legs which are designed to rest on the upper surface of the rim 22 of the toilet bowl. In FIG.
The pair of front legs of the legs of the toilet seat 18 are designated by the reference numeral 24, and the pair of rear legs are designated by the reference numeral 26.

As shown in FIGS. 2 and 3, the urine collection device 10 has a support 28 adapted to be attached to the front half of the rim 22. The support 28 is for pivotally supporting a swing arm 32 (described later) carrying a urine collection container 30, and is formed by injection molding of impact resistant resin or the like. The support body 28 is curved in a semicircular shape or a C shape along the contour of the substantially front half portion of the rim 22, and the upper surface 34 of the substantially front half portion of the rim 22.
Is placed on the rim to cover. As shown in FIG. 3, the support member 28 is provided when the toilet seat 18 is tilted to the use position.
It is formed in a shape that is almost hidden underneath.

As is best seen in FIG. 5, in accordance with a preferred embodiment of the present invention, the support 28 is located above the rim 22 with the top wall 36 extending upward, the outer peripheral wall 38 outside the rim, and the inside rim. It has a groove-shaped cross section defined by the inner peripheral wall 40. With such a groove-shaped cross section, the support 28 can be stably mounted on the rim 22. Further, since the front portion of the rim 22 is covered with the support 28, the front portion of the rim is not contaminated with urine or the like.

The top wall 36 of the support has a crescent-shaped extension 42 in plan view slightly protruding from the inner contour of the toilet seat 18 to the inside of the toilet bowl, as shown in FIG. As can be seen from FIG. 4, a slightly curved wall 44 located further inside the inner peripheral wall 40 hangs from the inner peripheral edge of the extension 42. As best seen in FIG. 5, the inner peripheral wall 40, the top wall extension 42, and the curved wall 44 form a crescent-shaped storage and washing chamber 48 that opens downward toward the toilet bowl space 46 of the toilet bowl 12. . The storage / cleaning chamber 48 is for storing and cleaning the urine collection container 30 and the swing arm 32 when not in use, as described later.

A lateral region 50 of the top wall 36 of the support 28.
(See FIG. 2) respectively support a pair of front leg portions 24 of the toilet seat as shown in FIG. As shown in FIG. 5, a plurality of reinforcing ribs 52 are preferably formed on the back surfaces of the side regions 50 so that these ribs abut the upper surface 34 of the rim 22. Therefore, a part of the weight of the user seated on the toilet seat is transmitted to these ribs 52 via the front leg 24 of the toilet seat, and this load is supported by the rim 22. Also, the support 28 is firmly fixed by the lateral region 50 being clamped between the front leg 24 of the toilet seat and the rim by the load.

However, due to the interposition of the lateral region 50 and the rib 52 between the front leg 24 of the toilet seat and the rim, the rear leg 26 of the toilet seat is slightly lifted, and a small gap is formed between the rear leg 26 and the rim. Will occur. Therefore, as shown in FIG. 4, by mounting a height adjusting spacer 54 having an appropriate thickness for compensating for this gap on each rear leg portion 26, the rear leg portions 26 are evenly supported by the rim. Preferably. Further, it is preferable to dispose a similar height adjusting spacer between the hinge shaft of the toilet seat and its supporting portion (housing 16 in the illustrated embodiment). With this configuration, the load applied to the toilet seat can be evenly supported.

As best seen in FIG. 2, the plane of the arcuate front region 56 of the top wall 36 of the support, which lies in front of the side region 50, is raised above the plane of the side region 50. It is adapted to be close to the outer lower edge 18A (see FIG. 4) of the toilet seat 18. With this configuration, when the toilet seat is tilted to the use position and viewed from the front, the toilet seat and the support 28
The gap between and becomes smaller, and it looks better when viewed from the front. However, even if a part of the top wall 36 is raised in this way, the top wall 36 has one continuous upper surface, and therefore can be extremely easily cleaned even if it is soiled with urine or the like. As described above, since the front portion of the rim 22 is covered with the support 28 and is not contaminated with urine, cleaning is not required. Therefore, only the support 28 needs to be cleaned, which can be done very easily.

There are many types of toilet seats on the market, and the mounting position of the front leg portion 24 differs depending on the type. Therefore, a predetermined front-rear direction expansion is ensured in the lateral region 50 of the support body top wall 36, so that the support body top wall 36 is adapted to the toilet seat where the mounting position of the front leg 24 is different. Therefore, regardless of the type of existing toilet seat, the urine collecting device of the present invention can be easily installed in the toilet without processing or replacing the toilet seat.

As can be seen from FIG. 4, in some commercially available toilet seats, in order to prevent the wash water from splashing to the surroundings from the gap between the rim and the toilet seat when the bidet device is used, The inner lower edge 18B is formed lower than the outer lower edge 18A. Even if the existing toilet seat is of this type, the inner lower edge 18B of the toilet seat does not interfere with the support 28, as shown in FIGS. 2 and 4, inside the front region 56. It is preferable that the region 58 located at the lower side is formed as low as the side region 50.
