Abstract
Abstract A vibratory therapeutic pad has an armature lying in a central plane, composed of a plurality of resilient ferrous metal strips each overlapping the next and encased in a body of foam-type material attached to the armature strips by adhesive. The overlapped parts of adjacent strips are also adherent to each other. This assembly of the armature embedded in the compliant foam body is inserted within an outer assembly comprising a sheet over which a coil is wound with foam material around the outside of the coil. Adhesive holds the coil conductors to the sheet and to the foam body. The pad can be bent or shaped to fit various parts of the human body and the vibration of the armature is substantially noiseless. Application of alternating current to the coil produces an alternating magnetic field through the armature which causes the armature strips to vibrate, and heat is produced to an extent permitted by thermostats in the circuit of the coil.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
101 words
A pad comprising: an electrically conductive coil for conducting alternating electrical current; an armature lying generally in a plane within said coil, said armature comprising a plurality of strips of magnetic material, each of which overlaps the next and generally lies in a plane oblique to the plane of the armature; and a body of compliant material covering and in contact with each side of said armature between the coil and the armature, the compliant material being adherent to the sides of the armature, whereby flow of alternating electrical current through the coil creates an alternating magnetic field surrounding said pad.
Claim 2
Dependent Claim
101 words
A pad comprising: an electrically conductive coil for conducting alternating electrical current; an armature lying generally in a plane within said coil, said armature comprising a plurality of strips of magnetic material, each of which overlaps the next and generally lies in a plane oblique to the plane of the armature; and a body of compliant material covering and in contact with each side of said armature between the coil and the armature, the compliant material being adherent to the sides of the armature, whereby flow of alternating electrical current through the coil creates an alternating magnetic field surrounding said pad.
Claim 3
Dependent Claim
14 words
A pad according to claim 1 in which the compliant material is a foam.
Claim 4
Dependent Claim
19 words
A pad according to claim 1 in which the overlapped parts of adjacent strips are adherent to each other.
Claim 5
Dependent Claim
24 words
