Hand held massaging tool
First Claim
1. A hand held massager comprisinga housing having an opening and a contact member provided with a contact surface portion lying in a first plane wherein the contact surface is configured to massage a portion of a human body;
- a handle enabling manual gripping of the tool;
an electric motor located inside the housing, the electric motor having;
a stator and an armature which, upon an electric current flowing through the armature, together produce a plurality of transverse linear forces facilitating a non-rotary translational motion of the armature in a second plane relative to the stator, the stator having;
on each of opposite sides of the armature, magnets and a backing plate to which the magnets are attached; and
, one or more spacing members that extend perpendicular to the armature and space the magnets from the opposite sides of the armature thereby creating a gap within which the armature moves;
wherein the handle is attached to one of the stator and the armature through the opening in the housing, and the contact member is attached to another of the stator and the armature, and wherein the first plane is parallel to the second plane, whereby the relative motion between the armature and the stator produces corresponding motion of the contact member relative to the handle; and
a resilient coupling coupled between the handle and the contact member and applying a bias against the motion of the contact member relative to the handle.

Abstract
A hand held tool 10 has a handle 14, a contact member 16, and an electric motor 12. The contact member has a contact surface portion 17 lying in a first plane. The motor 12 has a stator 23 and an armature 19. The armature 19 is able to move with non-rotary translational motion relative to the stator 23 in a second plane which is parallel to the first plane. One of the stator 23 and the armature 19 is attached to the handle 14, while the other is attached to the contact member 16. Relative motion of the stator 23 and armature 19 imparts relative motion between the handle 14 and the contact member 16. A resilient coupling 18 is coupled between the handle 14 and the contact member 16 and applies a bias against the relative motion between the handle 14 and contact member 16.
