## Background
FIELD OF THE INVENTION
The present invention relates to a rotatable and positionable bathing seat, in particular to an improved structure of a bathing seat that is installed at a selected position of a bath tub and used for assisting a physically disabled person to take a bath.
BACKGROUND OF THE INVENTION
As patients or the elderly have difficulties to enter and exit a bath tub, they usually rely on the assistance of a bathing seat and a nursing assistant for taking a bath, and the bathing seat has become one of the necessary nursing equipments. However, a traditional bathing seat is generally a fixed seat or a foldable stand with a size matched with the bath tub, wherein a cushion is coupled to the top of the stand, and the cushion comes with many drainage holes. The bathing seat is placed or fixed in the bath tub, so that the nursing assistant can help a patient or an elderly people to sit on the cushion in order to take a bath. The design of helping the patient or elderly to enter and exit the bath tub is still not taken into consideration in the traditional bathing seat, and thus patients and the elderly to rely on the nursing assistant's support or holding. Obviously, the use of such traditional bathing seat is inconvenient, and may even result in a serious consequence in a slippery bath room. As to other traditional bathing seats, some may come with a mechanical design to assist the patients or elderly to enter and exit the bath tub, yet the design is still not good enough or safe, and the traditional bath seats require improvements.
Therefore, it is a main subject of the present invention to design a bathing seat for assisting the patients or elderly to enter and exit the bath tub, so that the patients or elderly can take baths on their own or allow the nursing assistant to assist them to take a bath.
SUMMARY OF THE INVENTION
In view of the aforementioned shortcomings of the conventional bathing seat structure, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a rotatable and positionable bathing seat, so that the patients or the elderly can enter and exit the bath tub on their own or the nursing assistant can assist them to enter and exit bath tub more easily.
Therefore, it is a primary objective of the present invention to provide a rotatable and positionable bathing seat having an improved design with a rotating device and a positioning device installed between the bathing seat cushion and a base, such that the cushion can be rotated and positioned on the base, and the patient or the elderly person can sit on the cushion and turn into or out of the bath tub to achieve the effect of entering or exiting the bath tub, or allowing the nursing assistant to help them to enter and exit the bath tub more easily.
To achieve the foregoing objectives, the present invention provides a rotatable and positionable bathing seat comprising a cushion, a rotating device coupled to the bottom of the bathing seat, and a positioning device fixed onto a base for limiting the turning rotating device, characterized in that the rotating device includes an upper turntable coupled to the bottom of the cushion and a lower turntable coupled to the base, a spindle coupled between the upper turntable and the lower turntable, and a plurality of circularly arranged balls, and the lower turntable includes a plurality of circularly arranged positioning holes; and the positioning device includes a fixing plate coupled to the bottom of the cushion, and a press plate pivotally coupled to the fixing plate, and having a pivoting portion at the middle of the press plate, and an end of the pivoting portion forms a force applying portion, and another end of the pivoting portion forms a trigger portion, and the trigger portion is coupled to a positioning pin that can be passed into or separated from the positioning hole of the lower turntable, and an elastic element is coupled between the force applying portion and the fixing plate.
Therefore, a rotatable and positionable bathing seat of the present invention allows the patient or the elderly to sit on the cushion by fixing the base at a selected position of the bath tub and use the rotating device to enter into the bath tub for taking a bath or exit the bath tub after taking a bath. The positioning device is provided for fixing the cushion at a specific position, such that the patient or the elderly can take a bath, sit on the bathing seat or stand up from the bathing seat more safely.
