Abstract
The present invention relates to a rake head for a lawn or garden rake having plural rows of tines. The rake head includes a support member having a first and second edge. The rake head has a first and a second row of tines to be retained such that they have a substantially equal degree and range of movement and stress in a generally upward direction. Further, a first plurality of tines attached to a substantially planar support member defines a first plane that is intersected by a second plurality of tines attached to the support member and defines a second plane. Each of the tines of the second plurality of tines extends between and adjacent the tines of the first plurality of tines outside of the second edge. A separation of the tines is provided, thus forming two substantially identical rows of raking tines.
