DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention is based on a brush suitable for the care of the human body.
A brush of this type which is preferably intended for the cleansing or scrubbing of finger-nails and toe-nails within the area of the nail beds has become known from the prior published German patent specification DE 37 27 649 C1. This type of embodiment, however, is unsuitable for being utilized as a hand scrubbing brush, because there is only provided one plate-shaped brush member with the aid of which the cleansing or scrubbing of the whole hand is rather strenuous and time-consuming.
SUMMARY OF THE INVENTION
It is the object of the invention, therefore, to provide a hand-scrubbing brush which has a mains-independent motor drive and permits a cleansing or scrubbing of the entire surface of the hand inclusive of the finger-nails. The brush, of course, is also suitable for the cleansing or scrubbing of dirty feet and toe-nails.
In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a hand-scrubbing brush, in which the housing is formed as a kidney-shaped profile with one narrow side provided with a plurality of rotational bodies arranged rotatably along an arcuate or curved line adapted to the kidney shape, and a gear mechanism is provided for driving the rotational bodies by a motor in a form-and-force-locking manner.
In accordance with another feature of the present invention, the narrow side of the housing is formed as a bearing plate and a gar mechanism with the motor drive is mounted on it so that together with a removable, water tightly sealed grip sleeve, to form the housing.
In accordance with still another feature of the present invention, the grip sleeve and the bearing plate have a shape adapted to the natural arching of the palm of the human hand.
The rotational bodies can be formed so that they are pluggable into their positions.
The rotational bodies can be provided with bushings distributed in the bearing plate along two circular arc lines having different radii.
The gear mechanism can be designed so that the rotational bodies all rotate in the same direction of rotation, and the direction of rotation of the motor is reversible.
The rotational bodies can be equipped with clusters of bristles, and the clusters of bristles can be associated with neighboring brush rollers and also staggered and positioned so as to fill gaps.
The rotational bodies can be toothed or sprocket rollers which are circulated by an endless gear belt provided with bristles on the outer side.
The brush can be provided with the operational switch formed as a solenoid-operated switch with a switching magnet formed as a sliding contact.
Finally, the brush can be provided with a splash-proof enclosure which can slipped onto the grip sleeve.
The advantages which can be achieved when employing the invention are to be seen above all in the fact that there is provided a plurality of preferably cylindrical brush members disposed parallel in relation to one another both rotatably and interchangeably on a circular arc within the bearing plate of a kidney-shaped housing. The shape of the housing is adapted to the natural arching of the palm of the human hand. A gear mechanism is disposed between the driving motor and the brush members, and so designed that all brush members will rotate in the same direction. The brush rollers may be replaced by toothed or sprocket rollers via which an endless gear belt which, on its outside, is provided with bristles, is put into circulation.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
