ABSTRACT:
This invention relates to massagers, and more particularly, to bed massagers which create unique pulse/wave effects using two vibrating units which each contain two motors.
BACKGROUND OF THE INVENTION
Massagers arc available in a variety of configurations. For example, U.S. Pat. No. 5,730,707 discloses a device having two vibrating units which can be placed under a mattress or chair, wherein each motor/unit can be separately and variably controlled. Similarly, U.S. Pat. No. 5,545,125 describes a massaging device having two to sixteen motors which can be individually controlled. U.S. Pat. No. 5,462,515 discloses a massaging device having two vibrating units, and suggests that the motors which cause vibration can have different set powers or speeds. U.S. Pat. Nos. 5,140,976 and 4,559,929 disclose vibratory units having two motors, in which one motor is spaced at 90° relative to the other motor. However, all of these devices are limited in their ability to create unique pulse effects and wave effects, particularly with a simple, inexpensive control system. Accordingly, there is a need for a massaging device which provides unique pulse/wave effects. There is also a need for massaging devices which provide such unique effects with a simple, inexpensive control system.
Accordingly, one object of this invention is to provide new and improved massaging devices.
Another object is to provide new and improved massaging devices which create unique pulse/wave effects.
Still another object is to provide new and improved vibrating devices which create unique pulse/wave effects with a relatively simple, inexpensive control system.
SUMMARY OF THE INVENTION
In keeping with one aspect of the invention, a massaging device includes two vibrating units and a control unit. Each vibrating unit has two motors oriented at 90° relative to each other. The motors preferably have different power ratings, and are capable of operating at different speeds.
The control unit provides individual control of the two vibrating units. In addition, each motor in each vibrating unit can be separately and variably controlled. In at least one mode of operation, the speeds of a selected motor in each vibrating unit are fixed by the control system so that they necessarily operate at different speeds, out of phase with each other. The speeds of the other motors in the vibrating units are variably controlled over a range of speeds.
The vibrating units can easily be placed between a box spring and an upper mattress of a bed, horizontally separated at some distance. The device can also be used with a chair, a pillow or the like.
