Abstract

An electrically driven, hand operated and portable device for massaging the body. The device includes a pair of reciprocating patters which are timed so as to alternately pat the body. The drive is directly from the electric motor shaft, through a pair of gears, each of which have an eccentric pin mounted therein and which pins are each connected to their respective reciprocating patter through a follower member. The drive is easily assembled.

Claims

1. In an electrically driven, hand operated massager, the combination comprising;

a housing, an electric motor having a drive shaft journaled in said housing, said shaft having a spur gear at one of its ends, a pair of spur gears rotatably mounted in said housing and rotatable about axes which are parallel to said shaft, said pair of gears being in constant mesh with said shaft gear, each of said pairs of gears having eccentric pins extending from one side thereof, a pair of pistons reciprocably mounted in said housing and in a direction normal to the axis of rotation of said gears, said pistons having an inner end within the housing and having an outer end extending from the housing, a generally U-shaped follower fixed to said inner ends of said pistons for slideable embracing engagement with the respective eccentric pins of said gears, and a patter fixed to said outer end of each of said pistons whereby rotation of said gears by said motor causes reciprocating of said pistons and their associated patters, the relative positioning of said eccentric pins being such that said patters are reciprocated in opposite directions.

2. The massager set forth in claim 1 further characterized in that said housing has a removable front portion, and said pistons are reciprocably mounted in said removable portion whereby said pistons and patters are removed along with said front portion as a unit.
