The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to
The sole assembly 10 further comprises a first compartment 15 in the heel portion. A battery 2 is located in the first compartment 15. A plurality of second compartments 16 smaller than the first compartment 15 are formed between the insole 11 and the outsole and located in the instep and the forepart. Two vibrating devices 3 are located in the second compartments 16. A first switch 41 is electrically interconnected the battery 2 and the vibrating devices 3. The first switch 41 is exposed on a periphery of the sole assembly 10 for ease of operation. The first switch 41 is provided on an edge of a circuit board 40. The vibrating device 3 comprises a DC motor (not shown) and a cam shaft (not shown) driven by the motor for slightly vertically vibrating a bottom of the insole 11 when the vibrating device 3 is activating.
The sole assembly 10 further comprises a plurality of perforations 18 through the insole 11, a plurality of channels 17 formed between the insole 11 and the outsole, a heating element 5 fastened in the channels 17 and electrically connected to both the circuit board 40 and the battery 2, and a second switch 42 electrically interconnected the battery 2 and the heating element 5 and exposed on the periphery of the sole assembly 10 for ease of operation, the second switch 42 served as a switch for enabling the heating element 5 to heat the sole assembly 10 or not, and the second switch 42 provided on the edge of the circuit board 40 adjacent the first switch 1. The second switch 42 is implemented as a high and low selection so as to heat the sole assembly 10 to, for example either 150° C. or 50° C.
In use, a wearer may turn on the first switch 41 to activate the vibrating devices 3 to perform a first operation to massage the sole in cooperation with the projections 13. Further or alternatively, the wearer may turn on the second switch 42 to activate the heating element 5 to perform a second operation to warm the cold foot in either first temperature of 150° C. or second temperature of 50° C. The second operation is particularly applicable to cold weather. In either operation, air is drawn into the internal space including the grooves 12 of the sole assembly 10 through the perforations 18 prior to expelling out of same through a plurality of openings (not shown) formed on a periphery of the sole assembly 10. In brief, the provision of grooves 12 and perforations 18 aims at facilitating ventilation.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention has been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
