DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower apparatus which is mainly installed in a bathroom and which can be used in a sitting state.

[0002]

2. Description of the Related Art A conventional shower apparatus has a seat having a seating member attached below a backrest member, and the left and right sides of the left and right sides of the backrest member are pivotally supported at the base ends thereof. The left and right lateral bars are rotatably supported in a vertical direction between a forward position and an upward position, and the left and right lateral bars are provided with spray nozzles for spraying water toward a seat. It is known (for example, International Publication WO97-30619).

Therefore, in use, the left lateral bar and the right lateral bar are rotated from the upward position to the forward position in a sitting posture in which the user sits down on the sitting member of the sitting portion, and in this state, the left lateral bar and the right lateral bar are rotated. Hot water (water) was sprayed from a spray nozzle provided to take a shower.

[0004]

When such a shower device is used, when the user sits down on the seating member of the sitting portion, or conversely, stands up from the seating member, the handrail is used to ensure safety. Is desirably provided. However, in the conventional shower device, both left and right horizontal bars are:
Since the base end is supported in a cantilevered state only supported by a shaft, there is concern about the stability and support strength of the horizontal bar when using this horizontal bar as a handrail. In particular, for elderly people and people with physical disabilities, they tend to grasp the horizontal bar that is in hand, and if the stability and support strength of this horizontal bar is low, it may lead to accidents such as falls. Occurs.

Further, conventionally, since the horizontal bar provided with the spray nozzle is used by rotating it to the forward position, the distance from the spray nozzle to the foot is long, and the spray cannot be sufficiently sprayed to the foot. There is also a problem that the use in a standing posture cannot be performed because the use is intended in a sitting posture.

The present invention has been made in order to solve the above-mentioned conventional problems. By combining a horizontal bar with a vertical bar, a bar frame structure having high stability and high supporting strength is constructed. Can be sufficiently used as a handrail. In addition, another object of the present invention is to provide a shower device that can be showered on the feet and can be used not only in a sitting posture but also in a standing posture.

[0007]

In order to solve the above-mentioned problems, in the shower device of the present invention (claim 1), a seating member is foldably attached to a lower end of a backrest member.
Or, a seating member can be installed below the backrest member,
A left side bar and a right side bar are respectively provided at at least two positions above and below the backrest member so as to extend forward, and each side bar extends in the vertical direction around a shaft attachment portion on the base end side. A left vertical bar and a right vertical bar are rotatably mounted, and are rotatably mounted between the upper and lower left horizontal bars and between the upper and lower right horizontal bars, respectively. The bar is supported so that it can move up and down between the front side position of the stool and the upper side position, and when the vertical bar is moved to the front side position, the lower end of the vertical bar is on the floor surface. And a plurality of shower nozzles formed on the left vertical bar and the right vertical bar to spray water toward the seat.

[0008] In the shower apparatus of the present invention, a bar frame structure in which a horizontal bar and a vertical bar are combined on the left and right sides of the seat portion is configured. In this bar frame structure, a vertical bar is pivotally mounted between the ends of upper and lower horizontal bars that can rotate in the vertical direction, and the vertical bar is seated with the vertical rotation of the upper and lower horizontal bars. The vertical bar is formed so as to move up and down between a side front position and a side upper position of the part, and at the side front position, the lower end of the vertical bar abuts on the floor surface.

As described above, since the vertical bar is supported by the upper and lower horizontal bars, and the lower end of the vertical bar abuts on the floor surface at the side front position, the vertical bar can be stably supported. Yes, and the load applied to the vertical bar can be supported by the floor. Therefore, even when the vertical bar is used as a handrail when the user sits down on the seating member of the stool or stands up from the seating member, the load can be sufficiently supported by the bar frame structure, and is used as a handrail. Can be improved in reliability.

[0010] In the shower apparatus of the present invention, there is a mode (claim 2) in which a shower nozzle is provided at a lower portion of the vertical bar. In the shower device of the present invention, since the vertical bar is provided, if the shower nozzle is provided in a lower portion of the vertical bar, in a use state in which the vertical bar is positioned in front of the side, the shower nozzle is used by the user. Located at your feet,
You can shower at your feet.

Further, in the shower device of the present invention, there is a mode in which the shower nozzle is rotatably provided around the axis of the vertical bar. In the shower device of the present invention, when used in a sitting posture in which the user sits on the seating member of the seat, the vertical bar is positioned at the front side of the seat.
As described above, since the vertical bar is located at the front of the side of the stool, the shower nozzle provided on the vertical bar must face the stool with the rearward inward direction. In addition, when the user uses the standing member in a standing posture in front of the backrest member without sitting on the seating member of the stool, the vertical bar is positioned above the side of the stool. As described above, since the vertical bar is located above the side of the seat, it is necessary to face the front of the backrest member with the shower nozzle provided on the vertical bar facing inward. Therefore, if the shower nozzle is provided rotatably around the axis of the vertical bar, the orientation of the shower nozzle can be set freely, so that it can be used in a sitting posture and in a standing posture, and can be used only in a sitting posture. And it can be used in a standing position.

Further, in the shower apparatus of the present invention, the base ends of the upper left and right horizontal bars and / or the base ends of the lower left and right horizontal bars are integrated with both ends of the middle bar extended in the left and right direction of the backrest member. There is an embodiment in which a U-shaped bar member is provided, and the middle bar is pivotally mounted on the middle bar so that the left and right horizontal bars can be turned up and down. Each of the horizontal bars provided in the shower device of the present invention is configured to rotate vertically around the base-side shaft-attached portion. In this case, the horizontal bar is directly attached to the base end of the horizontal bar. When a force is applied to the horizontal bar, the load concentrates on the shaft attachment portion, and the shaft attachment portion is easily damaged. Therefore, by forming a U-shaped bar member in which the base ends of the left and right horizontal bars are integrally connected to both ends of the middle bar, and supporting the middle bar, the horizontal bar can be connected to the base shaft. While having the structure of rotating vertically about the attachment portion, the strength can be improved by the U-shaped bar member, and trouble such as breakage of the shaft attachment portion can be prevented.
