ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to an electric back scrubbing body brush, in general. More particularly, the invention relates to a back brush which employs an elongated arm, a soap reservoir within the elongated arm, and a rotating brush head coupled to an electric motor, designed for dispensing controlled amounts of liquid soap while providing an invigorating back scrub to hard to reach portions of the user's back.
Various references uncovered in the prior art provide hand-held electric devices for massaging or cleaning the skin of a user. For example, U.S. Pat. No. 3,699,952 to Waters discloses a skin treating appliance having a motor enclosed within a power handle which is arranged to drive a skin treating brush or massaging instrument through an elliptical orbit in a single plane. U.S. Pat. No. 4,027,348 to Flowers discloses another skin treatment appliance for use in the care of facial skin that drives an attachment piece in an orbital path to enhance massaging action to the skin. Likewise, U.S. Pat. No. 3,968,789 to Simoncini discloses an apparatus that moves a skin massaging element in rotary oscillation for massaging the skin.
However, most of these prior art devices have small hand-held casings specifically intended for use on the facial skin or the scalp for cleaning, massaging or applying creams thereto. Therefore, there is still a further need to provide a new and improved electric brush that is specifically designed for the back. Such an electric back brush should employ an electric motor to drive a brush head in rotary oscillation to facilitate a clean and invigorating back scrub. Moreover, such an electric back brush should permit self-administration of a scrub to various portions of the back, including hard-to-reach areas such as between one's shoulder blades.
While these units mentioned above may be suitable for the particular purpose employed, or for general use, they would not be as suitable for the purposes of the present invention as disclosed hereafter.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an electric back brush which is capable of reducing the amount of time necessary to clean the user's body, and yet is capable of providing an enhanced cleaning action to various portions of the back.
It is another object of the invention to provide an electric back brush which employs an electric motor for driving a brush head in a circular path to facilitate a clean and invigorating back scrub.
It is yet another object of the invention to provide an electric back brush with a speed control switch to allow a user to manually select the speed at which the brush head is to be rotated.
It is a further object of the invention to provide an electric back brush which utilizes an elongated arm to permit self-administration of a scrub to normally hard to reach areas of the back, including the hard-to-reach areas such as the upper center of the back.
It is a still further object of the invention to provide an electric back brush to facilitate the efforts of some physically challenged users to independently scrub their backs.
It is a still further object of the invention to provide an electric back brush which has a reservoir within its casing and a soap dispensing mechanism for selectively dispensing controlled amounts of liquid soap.
The invention is an electric back brush for providing a clean and invigorating back scrub comprising an elongated arm having one end attached to a handle and the other end attached to a head assembly. The length and shape of the elongated arm is designed to permit self-administration of the scrubbing action to various portions of the body, including the back. The head assembly includes an electric motor and a brush head attached thereto via a flexible drive shaft for driving the brush head in rotary oscillation while permitting the brush head to pivot freely with respect to the head assembly. The brush head is detachably mounted to the motor so that it can be removed therefrom and fitted with another brush head with different textures whenever desired. A soap reservoir is formed within the elongated arm for storing liquid soap so as to allow the user to selectively dispense soap while scrubbing his or her back with the brush head.
To the accomplishment of the above and related objects, the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.
