Abstract

<P>PROBLEM TO BE SOLVED: To take a bath in a relaxed posture, and to easily shampoo hair. <P>SOLUTION: A seat part 4 provided on the chair frame 26 of a chair unit 8 separable freely from a carriage unit 3 is respectively provided with the seat back part 5 and a footrest part 6 in a state where they can freely be reclined and locked at a plurality of angles, and the seat back part 5 is provided with a head support part 7 in a state where the head support part 7 can freely be reclined and locked at plurality of angles. Thus, the relaxed posture is kept sitting on the chair unit 8 in a reclined state where the angle of the seat back part 5 is adjusted, and the head support part 7 is inclined toward a rear side being an opposite side in an inclining direction at the seat back part 5 to prevent flowing water for shampoo from flowing to the side of the body of a person to be cared for. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a care wheelchair that can be moved in a sitting state by a cared person who uses a care chair mainly in daily life, and more particularly to a bathing care wheelchair that is convenient for washing hair during bathing.

Conventionally, generally, a physically handicapped person often spends sitting on a wheelchair in daily life.
In a care wheelchair, a care wheelchair is used in which the angle of the backrest portion is adjustable and tiltable with respect to the seat portion in order to make the care recipient's sitting posture comfortable.

However, when a care recipient takes a bath, the care recipient is placed on a sling seat or a simple chair having only a seat and a backrest, and is carried to a bathtub by a lift or the like for bathing.
However, in the sling seat, the cared person's body is curled up, and in the case of only the seat part and the dorsal part, the posture is fixed and cramped.
In addition, since there is no mechanism suitable for shampooing at the time of bathing, it is not easy to shampoo due to posture problems, or the running water for shampooing flows to the care recipient side. Had.

We do not conduct prior art searches at the research and development stage or application stage, and do not know the prior art documents to be described.

The problem to be solved is to provide a bathing care wheelchair that makes it possible to take a bath in an elongated posture or to easily wash the hair.

In view of the problem that bathing, in particular, hair washing, cannot be performed comfortably based on the above-described conventional technology, the present invention provides a backrest portion and a footrest portion that can be tilted and fixed at a plurality of angles, respectively, on a seat portion provided on a chair frame. At the same time, by providing the head support part on the dorsal part so that it can be tilted and fixed at multiple angles, the head support part can be maintained in a stretched position while sitting on a reclining chair whose angle is adjusted. The above-mentioned problem is solved by inclining to the back side, which is the opposite side of the inclining direction in the buttocks, so that the washing water does not flow to the body side.

In short, the present invention is a bathing care wheelchair in which a chair unit is detachably placed on a cart unit with casters, so that the care recipient can be easily moved to the vicinity of the bathtub and the caregiver sitting on the chair unit. The person can be bathed in the bathtub together with the chair unit.
In addition, since the back and footrests can be tilted and fixed at multiple angles on the seat provided on the chair frame, respectively, the backrest can be reclined or the footrest can be elevated,
It is possible to bathe in a relaxed and easy posture, and the head support part can be tilted and fixed at multiple angles on the dorsal part, so the head of the cared person is slightly behind the back part It is supported in a hung state, and the washing water does not touch the cared person, and the hair can be washed cleanly and easily.

Since the tilting and fixing mechanism of the tilting member of the chair frame and the backrest and the tilting member of the backrest and the head support is provided with an operating means, the tilting state can be easily adjusted, and the tilting member can be gripped. Since the holding material is provided, the cared person can grasp the holding material and perform the tilting and fixing work reliably, and the operation means and the holding material are arranged in a proximity position where the operation means and the holding material can be operated and held with one hand. Therefore, tilting and fixing can be operated in the best state while supporting with one hand, and stability and operability are further improved by supporting the back and head support portions with the other hand.

Since the base of the tilting rod is pivotally attached to the tilted member, a connecting member is provided in the middle of the tilting rod so as to be slidable and fixable at a plurality of positions, and the connecting member is pivotally attached to the tilting member. Because it can be tilted and fixed with a separate member that is substantially parallel to the angle, etc., the angle can be easily adjusted even when the cared person is seated. Since it is biased in the opposite direction, it can be securely fixed at a desired tilt angle when not operated, and an operation wire is provided between the pair of fitting pins on both sides as an operation means. It is possible to engage and disengage at the same time, and since a bar-shaped gripping material is provided in parallel with the operation wire, it is operated by operating the operation wire while gripping the bar-shaped gripping material that is easy to adjust to the hand. Can be disengaged from the tilting rod.

Since the guide frame is provided inside the chair frame mounting portion of the carriage frame, the chair frame can be easily placed on the carriage frame. Since it is provided, it can be positioned in all directions when descending from above.

The base end of the tilting rod is pivotally attached to the tilting member of the chair frame, and a connecting material is provided in the middle of the tilting body so as to be slidable and fixed at a plurality of positions, and the connecting material is pivoted to the tilting member of the footrest. Since it was worn, it was easy to adjust the tilt while the cared person was seated, and because the wheel was provided at the tip of the tilt bar, the wheel was grounded even when the chair unit was separated from the cart unit. The chair unit can be easily moved in the state.

The trolley unit can be folded by connecting the left and right frames of the trolley unit with a link mechanism, so that the trolley unit can be folded when bathing, ensuring a wide working space for bathing assistance and facilitating assistance. It can be done and its practical effect is great.
