Abstract

An auto cycling multi-functional massaging device having two to sixteen motor assemblies each of which is provided with an eccentric wheel and is retained in a housing, each of the housings is placed respectively in a space in a belt-shaped soft pad, and secured by a cover and a belt. The back of the belt-shaped soft pad is attached to a piece of sponge tape, the belt and the tape being sewn together. The ends of the belt-shaped soft pad are respectively provided with latching band for attachment to the waist. the motors are controlled by a control box, having a circuit board for controlling the time and the cycling vibration of the motors, and for controlling whether the motors are operated individually or all at the same time. The operating mode of the device can be changed by pressing switches on the control box.

Claims

1. An auto cycling multi-functional massaging device comprising:

a belt-shaped soft pad having opposite ends, a plurality of spaced apart protrusions opening outward on one side and a plurality of protruding strips between adjacent spaced apart protrusions;

a plurality of motor assemblies, each including a motor driven eccentric wheel to produce a vibration when rotated, a motor assembly attached to the belt shaped soft pad in each spaced apart protrusion;

a sponge tape having the same size as the belt-shaped soft pad attached to the belt shaped soft pad on a side opposite of the plurality of spaced apart protrusions;

a latching band at each opposite end of the belt shaped pad thereby enabling the belt-shaped soft pad to be attached to the body of a user and function as a massager;

an electrical circuit means connecting each of the plurality of motor assemblies to a circuit board of a control box having an integrated circuit and a plurality of control switches for controlling the operation of all the motors whereby the motors may be actuated in a predetermined sequence or simultaneously and whereby the time of operation of the motors may be controlled by the user.

2. The auto cycling multi-functional massaging device of claim 1 wherein each said motor assembly comprises:

a housing;

a motor and eccentric wheel in the housing;

a cover attached to the housing so as to enclose the motor and eccentric wheel;

an elliptical opening formed in a top of the housing;

a pair of screw posts on, two opposite sides of the housing having a center post and two side posts, each having elliptical arc-shaped surfaces, front and rear protruding semi-circular rings, and an intermediate protruding ring;

the cover having an extended portion extending beyond a periphery of the housing, with four corners of the extended portion having a substantially circular-arc-shaped portion, a bottom surface of the cover is provided with an elliptical protruding member having screw holes on an inner side of the protruding member aligned with the screw posts front and rear protruded plates extending between the screw holes, a top of each of the protruded plates formed as a concave are surface, a front portion of the cover is provided with a hole for feeding the electrical wiring through, whereby the motor is retained at the center post, and the rear side surfaces of the two side posts an end of the motor is retained by the rear protruded ring of the body and the rear protruded plate of the cover, the motor being secured in place by the front protruded ring, the intermediate protruded ring, the front protruded plate and the intermediate protruded plate, and the cover is secured to the housing by screws passing through the screw holes and the screw posts.

3. The auto cycling multi-functional massaging device of claim 1 wherein the electrical circuit means comprises a rectifying diode, a resistor, a capacitor and a zener diode connected between a power supply and a power switch for providing a stable voltage to the circuit board, the motors being connected to the integrated circuit through a plurality of resisters and a transistor, such that the motors are connected in parallel with each other, the integrated circuit providing a function selection, a time period selection and a motor selection, the control box being connected with the integrated circuit having a power switch to turn on the power supply, a function switch for selecting one of a plurality of predetermined functions, a time switch for selecting different operating time periods of the motors and a motor switch for selecting different motors to operate, whereby the electrical circuit comprises means to control the operation of the device such that, when power is turned on, each of the motors operate in a predetermined sequence and the operation recycles, when the function switch is pressed once, the motors operate sequentially in pairs in a clockwise direction for predetermined cycles for a predetermined period of time, after which the motors automatically rotate in a counter-clockwise direction for another predetermined cycle for a predetermined period of time before returning to rotate in the clockwise direction;

by pressing on the function switch twice, all of the motors start at the same time and the cycle feature is disabled;

by pressing on the motor switch, only one of the motors will operate;

pressing on the time switch for an incremental time, the motor operation time period will be increased gradually.
