ABSTRACT:
An apparatus for massaging a person's back of a type including a housing adapted to be positioned beside and above a bed. A back contacting portion is provided for rubbing the back of a person lying on the bed and a reciprocation mechanism is operatively attached to the housing for automatically moving the back contacting structure back and forth over a person's back. The reciprocating structure includes a frame with an endless flexible member thereon, such as a chain. the endless flexible member is joined at both ends thereof to allow it to move in an elliptical path. A cog is attached to the endless flexible member so that when the endless flexible member is driven, the cog will also travel in such elliptical path. A reciprocating member is disposed around the frame and has a first cog engagement portion in one side thereof for engagement with the cog when the cog is moving in one linear direction whereby the reciprocating member will be moved in such one linear direction when the cog is so moving. A second cog engagement portion is provided on the opposite side of the reciprocating member for engagement with the cog when the cog is moving in the second linear direction, opposite the first linear direction, whereby the reciprocating member will be moved in the second linear direction when the cog is moving in such second linear direction.
