The present invention relates to personal care appliances and, more particularly, to portable neck massaging appliances.
Various neck massaging appliances exist in a variety of forms. For example, known neck massaging appliances comprise an elongated, flexible pad or cushion containing one or more vibration elements comprised of an electric motor and a rotating eccentric weight to create vibrations. The pad or cushion may be U-shaped to conveniently be positioned partially around a user's neck.
Other massaging devices, though not specifically configured for or intended to be use for the neck, comprise large pads that are placed on seatbacks of chairs and that have one or more “shiatsu” style massage assemblies. Such assemblies include one or more rotatable, protruding massage members that may have symmetrical shapes or asymmetric shapes to cause a desired massaging effect.
No know appliances exist that provide a shiatsu type massage assembly in a small, portable sized and shaped massage appliance that is suitable to be used around a user's neck.
It is an object of the present invention to provide a portable massaging appliance, suitably sized and shaped for use around a user's neck, that has electrically-powered, motor-driven shiatsu style rotatable massage nodes. It is a further object to provide such a massaging appliance wherein the massage nodes are flexibly mounted to prevent discomfort and injury to the user.
These an other objects are achieved by the present invention disclosed herein.
According to the present invention, a portable neck massaging appliance has an electric motor that is battery-operated or that can be attached to an external electrical power source via an electrical cord. The appliance has a mechanical drive system associated with the motor for rotationally driving two massage nodes. Each massage node is mounted to a drive shaft via a spring that is rigid enough to transfer forces but that yields at a predetermined resistance force to prevent discomfort to the user.
Referring to
In operation, a user places the appliance 1 around his or her neck so that the central portion 3 is in contact with the back of the user's neck. The first and second arms 4, 5 rest on the shoulders pointing toward the front. The user activates the power with the on/off button 34 on the switchplate 33 and uses the control knob 35 to control hi/low/off for massaging function. The switch 34, rotary knob 35 and electronic circuitry for controlling the motor 13 are of a type generally known.
When the motor 13 is activated, its output shaft causes the worm gear 14 to rotate and drive the spur gear 15 which, in turn, drives the gear assembly 36. The gear assembly 36 is of a type generally known to those skilled in the art to convert output from the electric motor 13 into rotational motion being delivered to two output shafts, in this case being the rotating bases 19, 21 and their respective stems 20, 22.
The respective springs 23, 24 are each positioned over one of the respective stems 20, 22. The connector pins 25, 26 and the respective plates 27, 28 connect the nodes 11, 12, respectively, to one of the stems 20, 22. The springs 23, 24 permit some axial play between the stems 20, 22 and the nodes 11, 12.
As the user selects one of the speeds hi or low using the knob 35, the motor 13 causes the nodes 11, 12 to be driven rotationally. Contact is made with the user's neck by the extending section 8, in which the nodes 11, 12 are located and covered with a cloth or fabric that covers the entire appliance 1. The nodes 11, 12 impart massaging rotational and axial forces to the neck of the user. The springs 23, 24 flex if axial force sufficient to overcome them is applied, thus preventing discomfort or pain to the user. A thermostat 37, kapiton paper 38, and thermo cutoff switch 39 comprise a safety circuit. A mounting bracket 40 supports the motor and assembly.
