The detachment sensor 61s of the present embodiment uses a distance sensor (infrared sensor) for medium and long distances in consideration of the degree of freedom of installation, but uses at least one of electromagnetic waves and ultrasonic waves, not limited to infrared rays. It may be a distance sensor.
In this way, by detecting the separation by at least one of electromagnetic waves and ultrasonic waves, the measurement distance can be lengthened, and the degree of freedom in installing the separation sensor 61s is increased.

Further, the detachment sensor 61s is a sensor having directivity. As a result, the detection range is limited and the possibility of false detection can be reduced.

Next, an example of the configuration of the front board 61 will be described.
2 (a) and 2 (b) are schematic perspective views illustrating a part of the seating detection system according to the embodiment.
As shown in FIG. 2A, the front board 61 has a grip portion 62a and a fixing portion 62h. The fixing portion 62h is fixed to the wall surface 50RF of the toilet room 50R (see FIGS. 3A and 3B). As shown in FIG. 2B, the grip portion 62a is attached to the fixing portion 62h so as to be rotatable in the horizontal direction about the rotation shaft 62p provided on the fixing portion 62h. The grip portion 62a has a rotating arm portion 62b connected to the rotating shaft 62p, and a board portion 62c which is mounted on the rotating arm portion 62b and has a substantially semicircular shape in a plan view.

Further, an operation lever 62L (fixing mechanism, releasing mechanism) is provided on the portion of the rotating arm portion 62b of the front board 61 on the fixing portion 62h side. By moving the operating lever 62L away from the fixed portion 62h, the rotation (rotation) position of the grip portion 62a is released.

FIG. 2A illustrates a fixed state (locked state) of the operating lever 62L. In this state, the rotation of the grip portion 62a is fixed (locked). The position of the grip portion 62a is substantially fixed.

FIG. 2B illustrates the released state of the operating lever 62L. In this state, the grip portion 62a is rotatable. In the embodiment, it can be fixed at a plurality of positions. In the embodiment, the number of fixed positions is 4, but if it is 2 or more, this number is arbitrary.

Further, since the grip portion 62a of the front board 61 can be fixed in the rotational direction, it can swing within a predetermined range in the fixed state. The swing range at the fixed position is an angle of about 2 degrees plus or minus from the fixed position.

As shown in FIG. 2B, when the operating lever 62L is in the released state, the display 62D (for example, a display such as red) indicating that the operating lever 62L is in the released state may be visible. As a result, forgetting to lock can be suppressed, and the front board 61 can be used more safely.

One specific example of the position (rotational position) of the grip portion 62a will be described.
3 (a) to 3 (d) are schematic top views illustrating the seating detection system according to the embodiment.
FIG. 3A illustrates the first set position (use position) P1. 3 (b) to 3 (d) exemplify "other positions" (for example, the second set position (separation operation preparation position) P2, the third set position P3, and the fourth set position P4). There is.

At the first set position P1 illustrated in FIG. 3A, the user (assisted person) uses the toilet device 50. At the first set position P1, the sitting position of the user is held. In addition, the user's buttocks are washed at the first set position P1.

At the second set position P2 illustrated in FIG. 3B, the user stands up or keeps the user standing.

At the third set position P3 illustrated in FIG. 3C, the user may be transferred to a wheelchair or the like.

At the fourth set position P4 illustrated in FIG. 3D, the caregiver 82 assists the person being assisted who cannot be seated by himself / herself. The front board 61 and the toilet room 50R may be cleaned at the fourth set position P4.

At these a plurality of set positions, the grip portion 62a may be fixed. For example, the grip portion 62a can be fixed by a fixing mechanism (for example, the operation lever 62L) at a seating operation preparation position (second set position P2) different from the use position (first set position P1).

As shown in these figures, the distance between the grip portion 62a at the first set position P1 and the Western-style toilet bowl 50A is the grip portion at the "other position" (second set position P2 to P4, etc.). It is shorter than the distance between 62a and the Western-style toilet bowl 50A. At the first set position P1, the distance between the grip portion 62a and the Western-style toilet bowl 50A is the shortest. The grip portion 62a does not rotate in the direction approaching the Western-style toilet bowl 50A from the front of the Western-style toilet bowl 50A of the toilet device 50.

In the embodiment, the seating sensor 61s detects "leaving" (a state in which there is a possibility of leaving, a state before leaving) when the grip portion 62a is not in the first set position P1.
The separation sensor 61s is provided on the wall surface 50RF of the toilet room 50R, and the installation position of the separation sensor 61s in the height direction is substantially the same horizontal position as the front board 61. Here, the separation sensor 61s measures the distance between itself and the side surface of the front board 61 (actually, the rotating arm portion 62b).

In this way, the grip portion 62a can be set to the first set position P1 including the above-mentioned swing error and the "other position" by rotating. The position where the separation sensor 61s detects the separation is set to this "other position". That is, at the first set position P1 including the swing range, it is not determined to be "separation". When the grip portion 62a deviates from the swing range of the first set position P1, it is determined to be "separated". This "other position" is a position farther than the first set position P1 with reference to the Western-style toilet bowl 50A.

By setting the separation detection position to such a position (range), it is possible to suppress erroneous determination (false detection) regarding separation even when the grip portion 62a swings due to the movement of the user's body.

As described with respect to FIGS. 3A to 3D, the front board 61 is installed in front of the Western-style toilet bowl 50A. The separation sensor 61s detects the user's separation from the Western-style toilet bowl 50A by detecting the position of the grip portion 62a of the front board 61.

The fixing mechanism (operation lever 62L) of the front board 61 holds the grip portion 62a at a position (first set position P1) in which at least the longitudinal direction of the grip portion 62a is substantially parallel to the width direction of the Western-style toilet bowl 50A. Fix it. The grip portion 62a of the front board 61 is oscillatingly fixed within a predetermined range around the use position in a state of being fixed at the above-mentioned use position (first set position P1) by a fixing mechanism (FIG. 3). See (a)). The detection position of the separation sensor 61s is provided outside the swing range centered on this use position. As a result, even when the grip portion 62a moves due to the movement of the user's body, it is possible to suppress an erroneous determination (erroneous detection) of leaving the seat.

In the embodiment, the detection position is a position farther than the first set position P1 with respect to the toilet device 50. As a result, it is possible to prevent the movement of the user's hand or body during use from being erroneously detected as the movement of the grip portion 62a.

4 (a) to 4 (c) are schematic views showing a usage example of the separation detection system according to the embodiment.
4 (a) and 4 (b) are top views. FIG. 4C is a side view. In these figures, some components are seen through. 4 (a) and 4 (b) show a plurality of states to be detected by the separation detection system 110. 4 (a) and 4 (c) correspond to a state in which the user 81 (the person being assisted) is using the toilet device 50. FIG. 4B corresponds to the state after the user 81 uses the toilet device 50 and before leaving the seat.

Hereinafter, an example of using the toilet device 50 by the user 81 will be described.
As shown in FIGS. 4A to 4C, the toilet device 50 is provided in the toilet room 50R. The toilet device 50 includes a Western-style toilet bowl 50A and a toilet seat 51 mounted on the Western-style toilet bowl 50A. The toilet seat 51 is, for example, a warm water washing toilet seat.

An operation switch 50SW (button or the like) for various operations of the toilet device 50 may be provided on the wall surface 50RF of the toilet room 50R. By operating the operation switch 50SW, the buttocks of the user 81 (the person being assisted) are washed. In addition, the toilet bowl of the toilet device 50 may be cleaned by operating the operation switch 50SW.

The user 81 (assisted person) of the toilet device 50 enters the toilet room 50R with the assistance of the caregiver 82. The user 81 is assisted by the caregiver 82 and transfers to the toilet seat 51 of the toilet device 50. When the user 81 sits on the toilet seat 51, the caregiver 82 goes out of the toilet room 50R and closes the doorway 50E of the toilet room 50R.

By operating the on / off means 11 of the on / off means 10 by the caregiver 82, the on / off means 10 is set to the on state. As a result, the detection of the leaving of the user 81 sitting on the toilet seat 51 begins. A case where the user 81 tries to leave the toilet seat 51 is detected. At this time, the departure prediction information I is transmitted from the transmission means 20 based on the detection result of the departure via the on / off means 10. The caregiver 82 who received the departure prediction information I enters the toilet room 50R and provides necessary assistance.

In this example, a calling means 31 (for example, a calling button) is provided inside the toilet room 50R. The user 81 (for example, the person being assisted) can call the caregiver 82 by using the calling means 31 (calling button). The user 81 operates the calling means 31 (for example, presses the calling button) before using the toilet device 50 and getting up from the toilet device 50. Depending on the calling means 31, the caregiver 82 enters the toilet room 50R, and the caregiver 82 assists the user 81 in safely standing up. Then, with the assistance of the caregiver 82, the user 81 leaves the toilet room 50R.

In addition, the calling means 31 may be operated when the user 81 feels sick while using the toilet device 50. Necessary measures are taken by the caregiver 82 called by the calling means 31.

As shown in FIG. 4C, in this example, the above-mentioned on / off means 10 is provided on the outer wall of the toilet room 50R. As shown in FIG. 4C, in this example, the notification stop means 32 (for example, a recovery button), the corridor light 33, and the like are further provided on the outer wall of the toilet room 50R. By operating the notification means 32, various notifications from the notification means 85 can be manually stopped. By turning on the corridor light 33, for example, which of the plurality of toilet rooms 50R is in need of assistance is displayed in conjunction with various notifications. The on / off means 10 and the notification / stopping means 32 may be provided inside the toilet room 50R as long as the user 81 is seated on the toilet seat and is out of the reach of the user 81.

As shown in FIGS. 4A and 4C, when the user 81 uses the toilet device 50, the user 81 sits on the toilet seat 51.

When the user 81 sits on the toilet device 50, the grip portion 62a is set close to the front of the user 81 (see FIGS. 4 (a) and 4 (c)). In this state, the user 81 (the person being assisted) uses the toilet device 50. On the other hand, the grip portion 62a can be rotated to move to a position far from the user 81 (see FIG. 4B). This state is the state before the user 81 (the person being assisted) leaves the seat.

As shown in FIGS. 4A and 4C, when the user 81 uses the toilet device 50, the front board 61 is located near the front of the user 81. As a result, the user 81 can stably support the body while using the toilet device 50. The toilet device 50 can be used safely and conveniently.

On the other hand, as shown in FIG. 4B, when the user 81 leaves the toilet seat 51 after using the toilet device 50, the grip portion 62a is rotated toward a position far from the user 81. This facilitates separation from the toilet seat 51.

In this way, based on the difference in the positions of the grip portions 62a, it is possible to determine whether the toilet device 50 is in use or the toilet device 50 has been used and is in a state before leaving the seat.

In the embodiment, in addition to the detection of the disengagement based on the position of the grip portion 62a by the disengagement sensor 61s, the disengagement may be detected by the seating sensor provided in the toilet seat 51.

FIG. 4A illustrates the first set position P1. At the first set position P1, the user 81 uses the toilet device 50. FIG. 4B shows one example of the “other position” (second set position P2 in this example). At such an "other position", the user 81 stands up or the user 81 is held in a standing position.

Hereinafter, some examples of the detection position (detection area) will be described.

FIG. 5 is a schematic top view illustrating the separation detection system according to the embodiment.
As shown in FIG. 5, the detection position SP of the detachment sensor 61s is provided inside the front space region Rf in front of the use position (first set position P1) when viewed from the Western-style toilet bowl 50A. A straight line passing through the rotation shaft 62p along the direction from the rotation shaft 62p of the grip portion 62a toward the grip portion 62a at the first set position P1 is defined as a straight line L1. The straight line L1 is substantially parallel to the width direction of the Western-style toilet bowl 50A. The distance between the grip portion 62a and the Western-style toilet bowl 50A at the first set position P1 is shorter than the distance between an arbitrary point in the front space region Rf and the Western-style toilet bowl 50A.

If the detection position SP is located closer to the Western-style toilet bowl 50A than the first set position P1, erroneous detection is likely to occur due to the detection of the body of the user 81 or the like. Since the detection position SP is in the front space region Rf farther than the first set position P1, erroneous detection can be suppressed.

FIG. 6 is a schematic top view illustrating another seating detection system according to the embodiment. In this embodiment, the detachment sensor is provided not on the wall surface of the toilet room 50R but on the ceiling of the toilet room 50R (not shown). Here, the detachment sensor installed on the ceiling determines the movement from the first set position P1 to the "other position" by detecting the presence or absence of the grip portion 62a (rotating arm portion 62b and board portion 62c). And detect the departure.
As shown in FIG. 6, the seating detection position SP (detection range) by the seating sensor is large, sandwiched between virtual straight lines extending both ends of the Western-style toilet bowl 50A in the width direction toward the front side of the Western-style toilet bowl. It is provided inside the outside of the toilet bowl anterior region (at least one of the first region R1 and the third region R3).
In the second region R2 sandwiched between virtual straight lines extending both ends of the Western-style toilet bowl 50A in the width direction toward the front side of the Western-style toilet bowl 50A, erroneous detection due to the movement of the body of the user 81 or the like is likely to occur. By providing the detection position SP in the first region R1 or the third region R3, erroneous detection can be suppressed.

The detection position SP is formed in front of the Western-style toilet bowl 50A, has a width W of 35 cm or more and 50 cm or less, and has a large virtual center line in the width direction that substantially coincides with the virtual center line in the width direction of the Western-style toilet bowl 50A. It may be provided outside the front area of the toilet bowl. This width W (35 cm or more and 50 cm or less) corresponds to a standard shoulder width (see, for example, "Modification of Architectural Design Material-Human", Editor: Architectural Institute of Japan, Publisher: Maruzen Publishing Co., Ltd., etc.).

By providing the detection position SP outside the region having such a width W, it is possible to suppress false detection caused by, for example, the movement of the user's hand (including the arm).

FIG. 7 is a schematic top view illustrating another seating detection system according to the embodiment.
As shown in FIG. 7, in this example, the detection position SP (detection region) is the front of the outside of the toilet bowl front region (the first region R1 and the third region R3 illustrated in FIG. 6 or FIG. 7). It is provided on the rotation shaft 62p side (side space region Rs indicated by dots) of the grip portion 62a of the board 61.

For example, when viewed from the toilet device 50, the caregiver 82 approaches the user and assists the user from the side opposite to the wall surface 50RF. When the caregiver 82 performs detection in the area to be assisted, it is easy to detect the body of the caregiver 82 or the like. By performing the detection in the side space region Rs as described above, the possibility of erroneous detection of the body of the caregiver 82, for example, can be reduced.

FIG. 8 is a schematic top view illustrating another seating detection system according to the embodiment.
As shown in FIG. 8, in this example, the seating detection position SP (detection range) by the seating sensor 61s is Western-style at both ends of the board portion 62c in the used position (first set position P1) in the width direction. Of the outer region of the toilet bowl front region sandwiched by the virtual straight line extended to the front side of the toilet bowl 50A, it is provided on the rotation shaft 62p side (side space region Rs indicated by dots) of the grip portion 62a of the front board 61. To be done.

In this way, by providing the detection position SP in the side space region Rs, it is possible to reduce the possibility of erroneous detection of, for example, the body of the caregiver 82.

The center of the toilet device 50 in the width direction and the center of the board portion 62c in the width direction (left-right direction) do not have to be located on the same straight line.

FIG. 9 is a schematic top view illustrating another seating detection system according to the embodiment.
As shown in FIG. 9, in this example, the detection position SP (detection region) is the front of the outside of the toilet bowl front region (the first region R1 and the third region R3 illustrated in FIG. 6 or FIG. 7). It is provided on the rotation shaft 62p side of the grip portion 62a of the board 61 and in front of the Western-style toilet bowl 50A (side space front region Rsf indicated by dots).
The side space front region Rsf may be defined by the width of the front board 61 as in the embodiment shown in FIG.

The side space front region Rsf is a region where the front space region Rf shown in FIG. 5 and the side space region Rs shown in FIG. 7 or FIG. 8 overlap, and is used by detecting in this side space front region Rsf. In addition to the movement of the body of the person, the possibility of erroneous detection of the body of the caregiver 82 can be reduced.

FIG. 10 is a schematic top view illustrating another seating detection system according to the embodiment.
As shown in FIG. 10, in this example, the grip portion 62a of the front board 61 can be set to the second set position P2, which is one of the above-mentioned "other positions". Then, the direction from the fixed portion 62h at the first set position P1 toward the grip portion 62a is the first direction (direction of the straight line L1), and the direction from the fixed portion 62h at the second set position P2 toward the grip portion 62a is the second direction (the direction of the straight line L1). Assuming the direction of the straight line L2), the angle θ between these two directions is about 24 degrees.
In the present embodiment, the separation sensor 61s detects that the front board 61 has rotated to the second set position P2. The detection position SP is on the surface closest to the separation sensor 61s when the front board 61 is rotated to the second set position P2.

In this way, the detection position SP is separated from the first set position P1. By adopting such a detection position SP, for example, the initial setting of the detection position becomes easy.
The detection position SP is preferably set to the root side (rotating shaft 62p side) of the grip portion 62a of the front board 61 as much as possible.

Further, another seating detection system according to the embodiment will be described. As described above, the front board 61 may be provided with an operation lever 62L for fixing or releasing the rotation of the grip portion 62a. The separation sensor 61s may detect the separation by detecting the position of the operation lever 62L. For example, by detecting that the operating lever 62L has changed from the fixed position to the released position, the possibility of leaving the seat can be detected quickly.

Hereinafter, an example of the installation position of the separation sensor 61s will be described.
In the embodiment, the seating sensor 61s is preferably installed on the wall surface 50RF where the fixing portion 62h of the front board 61 is installed. Further, the separation sensor 61s is preferably arranged outside the rotation range of the grip portion 62a of the assistance device (front board 61). As a result, the grip portion 62a does not come into contact with the separation sensor 61s. Further, even when the grip portion 62a rotates at the largest angle (see FIG. 3D), it is preferable that a certain gap is provided between the grip portion 62a and the seating sensor 61s. As a result, it is possible to prevent a hand or the like from being pinched between the grip portion 62a and the separation sensor 61s. The width of this gap is, for example, 25 mm or more.

Further, the seating sensor 61s is preferably arranged in the front space region Rf (see FIG. 5) in front of the used position when viewed from the Western-style toilet bowl 50A. As a result, it is possible to suppress erroneous detection of the user's body or the like in the detection of leaving by the leaving sensor 61s.

Further, the detachment sensor may be provided in the first region R1 shown in FIGS. 6 and 7. In this case, the detachment sensor is installed on the ceiling, floor, or the like of the toilet room 50R. As a result, it is possible to suppress erroneous detection of the user's body or the like in the detection of leaving by the leaving sensor 61s.
Further, the separation sensor may be provided in the third region R3. In this case, the detachment sensor is installed on the wall surface 50RF in the third region R3 shown in FIG. 6, the ceiling, the floor, or the like in the third region R3. As a result, it is possible to suppress erroneous detection of a cane or the like placed in the first region R1.

As shown in FIG. 4C, it is preferable that the height of the seating sensor 61s is substantially equal to the height of the front board 61. For example, the seating sensor 61s overlaps at least a part of the assisting device (front board 61) in the vertical direction. For example, by making the distance between the grip portion 62a and the separation sensor 61s the shortest, the possibility of erroneous detection can be reduced.
